Gaining New Sisters Who are Devils!

A young man is seen in his bedroom and at his desk doing a few drawings of people in cool looking costumes like superheroes in the anime shows and manga, with his room being filled of his favorite superhero anime stuff like posters and limited-edition action figures.

"Izuku, sweetie! It's time to go!" A woman called out to him.

"Okay mom, I'll be right down!" The boy named Izuku responded.

"You better come down or else I'm gonna drag you down!" Another woman shouted in rage.

"Yes, mother!" Izuku flinched in fear a bit, but he knew his other mom means well to him.

Izuku is 15-year-old boy though somewhat short for his age, his round face is framed by a short mop of fluffy dark-green hair which curls up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, their irises the same shade of green as his hair. He wears a green jinbei over a white shirt, gray sweatpants, and somewhat big red shoes.

"Mom Raphaeline said she got a big announcement she and Mom Sapphire has; I wonder what it could be?" Izuku asked himself as he leaves the room.

(Later, Burger-Noodle Restaurant)

"WHAT?!" Izuku screamed in shock of the sudden news his two moms told him, and almost dropped his burger.

"I'm getting two new sisters?!" Izuku gasped.

"That's right, we decided it's time to extend our little family into a slightly bigger one!" Raphaeline nodded with a cute smile.

Raphaeline is a beautiful buxom, young woman with long hair and green eyes. She wears a white long sleeve mini dress and donned a brown belt with a gold buckle that's in the shape of wings with a halo above them, and white high heel boots. Breasts size: J-cup.

"Oh man, this is so sudden and you two really decided on doing this now?" Izuku asked shock.

"Well, it wasn't easy, believe me. When you mom brought up the idea of getting you little sisters, I thought she was crazy that we have to let ourselves by fucked by some guy we knew." Sapphire said without shame.

Sapphire is a beautiful buxom, young woman with red hair and red matching eyes. She wears a red tank-top showing the bottom-half of her bosom, black strap panties with an orange skirt-like cloth that allows most of her buttocks to escape, long black stockings, and orange small boots with yellow toes. Breasts size: K-cup.

"But I made it clear that we don't have to go through pregnant process and choose the adopting part." Raphaeline added.

"Okay, so I'm getting my own sisters. How old are they?" Izuku asked, becoming curious about his new little sisters.

"Thought you ask that; one is about a little older than you, probably a year older while the other one is the same age as you though months below you." Sapphire answered.

"So, I'm getting one older sister and one younger sister. This is still crazy for me; I didn't think I'd get any siblings now of all times." Izuku said.

"Izuku, didn't you ever thought about wanting your own siblings. I believe it was years ago when you were younger." Raphaeline mentioned.

"I can't remember some of my childhood, but maybe I felt something like that along the way." Izuku mentioned while finishing his burger.

"Yeah, better late than never. But even so, those two are sure taking so long to get here." Sapphire angered.

"I'm sure they have their reason for being late. Although I do feel worried, they were supposed to be here five minutes ago, maybe we should call the police!" Raphaeline concerned.

"I don't think we need to involve the police; I have a feeling we'll meet them soon." Izuku believed.

"So, that famous Deku instinct. Never fails." Sapphire chuckled.

"If your father and were here, they would be so proud of the young man you have grown to be." Raphaeline smiled at her son.

"Oh, come on, I'm not that special." Izuku stuttered and tried covering his face.

"Hey now, you're making yourself embarrass of the Tojo family name. At least try to make yourself look tough when you meet your new sisters." Sapphire scolded.

"I'm sorry!" Izuku flinched a bit.

"I'm gonna go to the bathroom. Be right back!" Izuku left the table and went onward to the bathroom.

"Hey, don't you think we should tell him?" Sapphire asked.

"About what, beloved?" Raphaeline asked as she moves her hand onto Sapphire's hand.

"You know damn well what I mean, about his two new sisters. Don't you think he should have the right to know about them, about what they really are?" Sapphire asked, with a deep worried expression in those tough eyes of hers.

"I feel bad about not telling Izuku the truth about those girls, but I believe he needs to discover this on his own and I hope that will help him overcome suffering he went through ten years ago." Raphaeline stated, then felt her wife's hand closing onto hers.

"That incident… Can't believe it's gonna come down to that, I sure hope you're right about this." Sapphire turned to press her forehead onto Raphaeline's.

"Oh please, have I ever been wrong before?" Raphaeline asked giggling.

"Well, there was that one time you tried to combine all those hot sauce in boiling water and set the kitchen on fire." Sapphire reminded her wife of that time.

"Hey! I was trying something new! How was I supposed to know that the sauce would suddenly burst into flame?" Raphaeline asked wincing.

"God, you act like such a kid." Sapphire giggled and kissed her on the lips.

Meanwhile with Izuku, he is having some thoughts about the news of gaining two new sisters.

"I'm going to be a brother, a middle brother to be exact though I'm really nervous about this. What if they don't like me and I rest up the relationship my moms are hoping to create? I know things are hard for them since dad died around the time when I was only a baby and I don't know much about him, but still I have to do my best to make those girls feel they are part of the family and…" Izuku mumbled on about how to make this work for everybody in the family.

However, he was too distracted in his thoughts that he didn't realize that there was someone else in the bathroom, it also didn't help that the bathroom was never locked when he opens it and saw a girl inside just about to lift up her underwear.

When both Izuku and the girl met eyes and realize the scene that is happening right now, Izuku's face started to light up like a red Christmas tree and look over at the sign next to the door.

"(The lock is broken. Make sure you knock.)" Izuku thought read the sign.

"(I DIDN'T SEE IT!)" Izuku thought screamed

He and the girl let out a very loud very and threw her hand right at Izuku for a hard slap.

"Izuku! Was that you, honey? We heard screaming!" Raphaeline asked as she and Sapphire came to the bathroom.

"Anyone who hurts my son will get it!" Sapphire angered.

But both mothers look at the scene of their son on the floor groaning in pain with steam coming from his cheek and the red hair girl standing over Izuku, and one other girl standing with the two mothers.

Minutes later, after Izuku regain consciousness and outside started raining, the Tojo family and the two new girls sat together to start with the introduction.

"It's nice to meet you. I'm Maria Naruse." Maria introduced herself.

Maria is a petite beautiful girl with long silver hair and purple eyes in her human form most of the time. She is seen dressed in a black dress that has white frills most of the time and what seemed to be like a functional keyhole on her collar, black leggings, and boots that have a purple heart on them. Breasts size: AA-cup.

"I'm Izuku Tojo. It's n-nice to m-meet you." Izuku greeted nervously and feeling bad about the bathroom thing.

"I'm Mio Naruse." Mio revealed her name.

Mio is a beautiful young woman shorter than Basara with long crimson hair reaching her waist and pink eyes. For someone her age, she has been noted for having a distinctly slender yet curvaceous figure with enormous, bouncy breasts and sizeable buttocks. She wears a purple shirt with a pale blue dress-like shirt on top, thigh-length black socks, and fancy red shoes. Breasts size: G-cup.

"Thank you for coming to see us, I know the first meet wasn't how we planned, but we can promise you that Izuku is a lovely boy and the kindest one you'll ever meet." Raphaeline petted her son's head.

"But he can be a wimp sometimes. So, try and help us toughen him up if you can." Sapphire said.

"Mom Sapphire, please don't make it sound like it's okay to beat me up!" Izuku exclaimed.

"Isn't he cute when he's blushing!" Raphaeline giggled.

"Anyway, let's get going. We have a new house to get settle in." Sapphire smirked.

Izuku looks over to Mio hoping she would at least spare a second to look at him, she did and just turns her head to the side with a huff showing that she is still mad at him about what happened earlier.

"(Earning her trust is gonna hard now.)" Izuku thought sighed.

(The Next Day)

Morning has come and Izuku is sleeping wonderfully on his bed, or at least a second ago until he felt something weighing on his body and groans a bit.

He opens his eyes and the first thing he sees in the morning are a pair of big boobs above his face and his eyes widen with shock.

"Oh! You're finally awake! Good morning!" Mio greeted, revealing herself sitting on top of Izuku.

Izuku screams though only for a second with his face turning completely red and his heart beating like shit crazy.

"Did you sleep well?" Mio asked.

"Y-Yeah, I'm awake! And w-wondering why are y-you in my r-room?" Izuku asked stutter and freaking out.

"I came here to wake you up. I thought that a teenage boy would like to be woken up this way." Mio explained.

"I'm pretty sure I'm not one of those teenage boys who are into things like that. Where did you even get an idea like that?" Izuku asked.

"Just performing service. Also, Mother Raphaeline told me that she used to wake you up by pressing her body onto you." Mio mentioned.

"(Oh, mom! Why did you tell her that?)" Izuku thought exclaimed.

"But was it really necessary to do this sort of thing?" Izuku asked.

"I'm just here to help you get up and get ready, okay?" Mio said as she started rubbing her button onto Izuku causing her breasts to bounce as well.

"M…M… Mio…!" Izuku tried to say she should really get off, but the words wouldn't come out of his mouth for some reason.

But then Mio stop as she felt something from under the sheet.

"Oh? What's this? I think I can feel something hard under the sheets." Mio wondered.

"Okay! I'm awake now, so you should really get off!" Izuku begged as he fears that the arouse is getting to him, and he almost screamed when Mio went under the sheet.

"(Holy Devil! What is going on here? Are we really about to do something incent even though we're siblings now!)" Izuku thought panicked.

"Huh, what's this?" Mio wondered as she is holding a box in her hands, and then she suddenly threw herself back and fell on the floor. She also threw the box that hit on Izuku's face.

"Mio? Are you okay?" Izuku asked, concern for Mio's safety.

"Yeah, I'm fine." Mio answered.

Then Izuku notice the box next to him and picks it up to get a closer look and saw this box to be strange with a picture of a girl sitting on a bed and her underwear expose. The title is also strange that it's called "Me and My Real Stepsister's Youth in an Unmarked Lot".

"Huh, what is this and why is it in my bedroom?" Izuku confused.

"How dare you! We're all living here together under one roof and you're playing games like that?! Gross, I knew it!" Mio disgusted at Izuku as she crosses her arms under her breasts.

"Wait, wait, wait, it's not what it looks like! Even though I don't know what you mean, and I don't even know what this game is!" Izuku tried to declare his innocence.

But as he stands up on his bed, his foot suddenly trips on the sheet causing him to fall over on top of Mio. Now both are on the floor with the boy on top and their faces are very close to each other.

"(Oh no, I'm somehow making it worse!)" Izuku thought panicked.

"Hey! Get off of me, you pervert!" Mio demanded and threw a knee right in Izuku's manhood causing him to gasp and fall over on the side.

Mio gets up and leaves Izuku's room.

"If you ever try something like that again, I'll kill you a hundred times." Mio threatened.

"No wait, I'm innocent! I'm not a pervert!" Izuku tried to reason with Mio while holding onto his manhood, but Mio just left.

Izuku just lays on the floor sighing that his chance to make peace with Mio has been foiled again, and then he thinks about yesterday at this new house they moved in.

"This house isn't so bad, but I still say we could've gotten ourselves a bigger one." Sapphire stated.

(Flashback)

Izuku is standing outside of the house on top of the stairs with his two moms at the bottom of the stairs.

"It's fine, the house is in very good condition even though the price was very cheap for some reason." Raphaeline said.

"The girls have also gone through some tough things in the past including losing their parents not too long ago. In fact, Maria doesn't even want to go to school anymore which saddens me." Raphaaeline explained about the two girls.

"Oh, I'm so sorry for them." Izuku said.

"Hey, Izuku. Are you mad at us?" Sapphire asked, getting the boy's attention.

"I mean we basically just moved out of our old house and bragged you along without giving you any sort of explanation." Sapphire pointed out.

"Well, I am sad that I have to say goodbye to my friends and transfer to another school. But I'm not mad at you guys, I could never do something like that." Izuku answered making the mothers feel relieved.

"Also, I have a feeling there is a big reason why we're all together. Why you decided to adopt them and have them live with us." Izuku said.

"Yeah, you could say there's something big going on." Raphaeline nodded.

"Now the question is, are you prepared to protect them with all your might?" Raphaeline asked.

(Flashback End)

"(Protect them.)" Izuku thought repeated the words in his head as he walked down the stairs to the kitchen.

"(I may not know what this danger that I'm supposed to protect them from, but I swear I will do whatever I can to help them.)" Izuku thought promised.

Izuku walks into the kitchen where Maria is doing some cooking right now and notices him coming in.

"Oh, Izuku! Good morning!" Maria greeted.

"Good morning, Maria." Izuku said as he took out some milk from the fridge.

"Breakfast will be ready soon." Maria informed.

"Oh, thank you! I didn't you could coOOOOOOOOH?!" Izuku gasped in shock.

"Huh, what is it? Is something wrong?" Maria asked. The little girl is shown to be wearing an apron, and it appears that she is only wearing the apron.

"Something… I, huh… Maria, why are you d-dress like that!" Izuku asked with his cheeks blushing again.

Maria was a little confused at first until she looks down at her apron and got an idea in her head.

"I get it. You thought I wasn't wearing anything else. Too bad!" Maria twirled around to reveal her green and white stripe underwear. "I'm actually wearing underwear today!"

This causes Izuku to blush even harder and crushing the cardan of milk in his hand.

"I can see why you got all excited! You are a healthy teenage boy after all! Right?" Maria teased.

"No, no! I wasn't thinking of anything bad! I swear?!" Izuku exclaimed.

And so, Izuku's first day of having two sisters started off with a high note.

KO a new story is born and hope you all enjoy it!

Decided to make a little My Hero Academia and Testament of Sister New Devil crossover with Izuku replacing Basara entirely as the main character, and in this story both mothers of Angels and Demons are here raising him. This is for the final anime airing of the show since we never got season 3.

The Promise to Protect His Family

"Oh yeah!" Maria realized what she wanted to ask her new big brother something.

"How did you like your gift? Did you get my move-in present?" Maria asked.

"Move-present? I think I got something, but could you please tell me what that is?" Izuku asked politely.

"(This boy is so polite and timid a little, it's so cute. It's a shame that we may have to use him for our own purpose.)" Maria thought giggled.

"Me and My Real Stepsisters: Youth in an Unmarked Lot." Maria mentioned the title and that soon clicks very hard in Izuku's head.

"What?! The game box… That was you! But why would you even buy a game like that?" Izuku asked with his face flustering all red.

"I thought you could use it as a guide from now on." Maria answered.

"Guide for what? Becoming a pervert which I hate!" Izuku yelled a bit in shock.

"Oh, come now. Is there anything you want a stepsister to make her to your liking in that head of yours?" Maria giggled and swayed her hips.

"(Unholy Crap! This girl is insane with lust, mostly the opposite of Mio!)" Izuku thought shocked, comparing his two new sisters to each other. Wondering if Maria does this to Mio too in the past.

"Not exciting enough? Oh, you probably think the game is boring, so why not do it with me in real life?" Maria offered as she lifts up the apron just a little to show off her legs.

"No! No! No! No! Please, don't do that?!" Izuku yelled a little loudly while waving his arms side to side in front of his face.

"The fuck is with all the yelling about? It's still so early in the morning?" Sapphire asked, coming in with a yawn followed by Raphaeline and Mio.

"Oh, well, you see, Izuku is about to take me however he wants for the first time." Maria lied as an embarrassing tease to Izuku.

"I promise it is NOT like that!" Izuku stated.

"It looks like Izuku has now found out about Maria being the embarrassing pervert little sister, I wonder how his little heart will take it." Raphaealine giggled, seeing this being a little funny.

"It's not funny at all, Mother!" Izuku screamed with his face going steaming red.

"If you even think about giving in to Maria's silly pervert antics than I'm going to give you a scolding of a lifetime you will never forget!" Mio warned with a scary glare. She knows that Izuku isn't a total pervert thanks to the good words from his moms, but she'll still have her guard up around him.

"Now, now, let's have ourselves some breakfast and we take our family photo together!" Raphaeline suggested with a kind smile.

"Wonderful idea, I just about to finished making breakfast! I hope you're hungry because my cooking is up notch!" Maria winked at Izuku.

"(Oh boy, this girl is going to make me feel crazy…)" Izuku thought sighed.

Everyone ate their breakfast together without any more issues with Maria trying to be all perverted to her new stepbrother, everything went well and the whole family steps outside to have their new and first family photo taken.

"Izuku, try to calm yourself down. You look stiff as a tree." Raphaeline advised while holding the camera.

"Right!" Izuku flinched a bit.

"Come on, son, you're acting like it's the end of the world. Our family is expanding and we're going to make this work however we can." Sapphire stated with a light pat on his back.

"Right." Izuku nodded then puts on a smile.

"That's a cute smile, you got there." Mio complimented, seeing Izuku smile like that.

"You really think so?" Izuku asked, a little surprised that Mio is being a little nice to him now.

"Yeah, you should try wearing that more often. Maybe people would take you seriously from now on." Mio stated.

"(Bold and honest, more than me in a way. Maybe having sisters won't be so bad, it could be fun.)" Izuku thought smiled and face the camera.

"Okay, I'm setting the timer." Raphaeline pressed the button and hurried over to the family.

"(Dad, big brother. I hope you two are watching over us from Heaven, me and moms are doing okay.)" Izuku thought hoped his dead father and big brother knows that the family doing okay.

And then, the picture was taken of the entire family now coming together.

(Later)

Izuku and Mio were sent off to do some grocery shopping upon the request of Raphaeline thinking they might need a little bit more food since they have two new mouths to feed, and to give them a chance to spend time together.

"Okay, we got everything we need." Izuku said, looking over the bags to make sure they got everything from the list.

"I believe so, Mother Raphaeline sure has a lot on the list to make sure we don't go hungry." Mio commented.

"Yeah, she cares a lot to make sure that we have everything we need to get through while also making sure not to spend too much money." Izuku explained.

"I'm gonna go get the bike. You wait here until I get back." Izuku ordered before running off to get the bike.

Mio let out a sigh and looks up at the blue sky, thinking about how her life is like now that she has a little brother and two mothers in her life now which is still quite surprising to her, but it's also warming and joyfully though she looks a bit sad for a second.

"Hey, baby. Are you all alone?" One guy with a baggy red hat asked grinning, he and few of his pals walking up to Mio.

"Wanna go have some fun with us?" One dirty blonde guy asked.

The five punks gang up on Mio seeing how she is so cute and sexy at the same time; one grabs her by the shoulder to "convince" her to come with him but Mio wasn't having any of that.

"Don't touch me. Do that again and I'll kill you a hundred times over." Mio threatened as she smacks the hand away.

"You're gonna kill us?" One dark skin punk chuckled.

"I like to see you try. Come on." The red baggy hat punk dared Mio to try doing that little threat.

Mio was getting really uncomfortable with how these stupid men are trying to have their way with her like a defenseless girl, but she knows that she can't do anything or else she might blow her cover.

"Excuse, but I'm gonna have to ask you to leave my big sister alone." Izuku demanded, coming back with a bike.

"Oh, Izuku!" Mio surprised and relieved to see him back.

"Izuku? What kind of lame-ass name is that?" The red baggy hat punk asked, mocking Izuku's name.

"Better than whatever lame name you got." Izuku mocked back, trying to be brave for Mio.

That got the red baggy hat punk angry from hearing that and wanted to give a punch in that little brat's face, but never got the chance because Izuku thrust the palm of his hand to send the guy back and knock him down along with two of his friends.

"You little shit! You're going to pay for that!" One punk with a candy Jolly Roger angered.

"Oh my, what do we have here?" A girl's voice asked in a giggling tone.

Suddenly all the punks became scared feeling the shiver of fear going down their spines, they look like they're afraid of a ghost coming to them right now, and it's happening right now.

"Don't tell me that you naughty boys are pulling your shits again on an innocent girl." The girl walked up to the scene.

"Oh shit, it's Kimi Aoi!" The dark skin punk gulped in fear.

"Why did she have to come here, of all places!" The blue hoodie punk exclaimed.

"(Kimi Aoi, they're afraid of that girl?)" Izuku thought wondered.

"So, were you boys being naughty because I'll have to give you my Dancing Punishment." Kimi grinned.

Kimi is a girl with dark brown eyes and long wavy light brown hair that is adorned with lengths of white cloth, the length of the hair is all the way down to the legs and just above the feet. She is well-endowed and her figure is mature for someone of her age. She wears a violet color short sleeve shirt with a pink flower symbol on the front, light blue pants, and white shoes with raspberry color flower designs. Breasts sizes: K-cup.

"No, please don't! We weren't looking for any trouble! I swear!" The red baggy hat punk said, freaking out.

"Yeah, we were… Just leaving!" One ran for his lift and soon, the rest followed.

"(Whoa, is this girl like a big boss or something?)" Izuku thought amazed a little.

"I swear, those fools need to better themselves or else they'll find themselves with their cheeks very red. And I don't mean their faces." Kimi swayed her hips while walking toward the new faces.

"You're the new neighbors, it is very nice to meet you for today is your lucky day to be in the presence of Kimi Aoi!" Kimi greeted.

"Nice to meet you. I'm Izuku Midoriya, this here is my older adopted sister Mio Naruse, I guess you could say my stepsister as well." Izuku introduced himself and Mio.

"It is nice to meet you." Mio greeted.

"So, how did you know that we've moved here" Izuku asked.

"I live in the same neighborhood, so I would know about what goes on around here and I actually wanted to greet you all." Kimi answered.

"I'm also out here with a little friend of mine who wanted to get some snacks here." Kimi gestured at the small grocery store.

"Oh, and speak of the devil, here she comes." Kimi looked over to see a short girl coming out of the store.

"Hey Kimi, I'm done." The girl said.

"And just in time too, Philip! These two are the new neighbors, Izuku and Mio." Kimi gestured to the two new friends.

"Hello." Izuku greeted.

"Nice to meet you." Mio smiled.

"Hi, my name is Philip Burgundy, I do hope we can be friends." Philip greeted politely and bow at the two.

Philp is a short girl with white-like skin, short black hair and two bangs on each side longer closer to her shoulders, and brown eyes. She also wears a dark blue headband. Her clothing is consistent of a dark style dress with long and side sleeves, grayish white fur on the neck area, a black bowtie, black and purple pattern from the neck straight down to the skirt and little gold buttons, a three-point short cape with the same fur, brown legging socks with white ones underneath, and dark blue shoes. Breasts sizes: AA-cup.

"That's a cute outfit you're wearing, like a min-goth!" Mio complimented on Philip's outfit, finding her to be really cute.

"Thank you, it's my own style." Philip smiled, blushing a bit from the compliment.

"Anyway, thank you for saving us from those punks. I was thinking about having to make a run for it on the bike with Mio." Izuku thanked Kimi.

"You're very welcome. I always had to deal with those silly boys like them if they don't behave in my territory, otherwise I'd have to punish them." Kimi chuckled.

"Punish them. What are you, a Yazuka?" Mio asked shock.

"Maybe I am, maybe I'm not, that's a mystery you'll have to find out for yourself." Kimi winked.

"Well, what you guys do need to know is that Kimi is strong in her own way." Philip mentioned.

Izuku starts to become curious about this Kimi girl who seems like a very kind and exciting girl along with the beauty that others would go crazy for like her big breasts, but he can tell there is something else about this girl that makes her frightening to those punks to run away at the first sight of her.

And he found himself staring at her big breasts again, which he quickly shook his head.

"You know, you two might end up going to the same school we go to which means you'll be seeing a lot more of us around from now on." Kimi said.

"Okay, we'll look for you two once we get settle in our new house." Izuku nodded.

"Yeah, I would love to get to know you more and learn some things too!" Mio clapped her hands together.

"(Especially with how in the fucking world do you have such giant boobs?!)" Mio thought glared at Kimi's giant boobs. This reminds her of Izuku's mom, Sapphire with her own giant breasts.

"We better get going." Izuku said with a hand on Mio's shoulder.

"Bye." Izuku said as Mio is sitting behind him on the bike, and they ride away while Kimi and Philip waves goodbye to them.

"So, what do you think of them?" Philip asked.

"Those newly arrivals are certainly something. I don't know what that is about those two, but I can say for certain that things are never going to be the same from now on." Kimi smiled.

Izuku rides that bike through the streets taking the route back to the house to finish their grocery shopping, but the dark green hair boy has another idea to make this a special day for Mio.

"Hey Mio, I'm going to take you somewhere that you might like." Izuku said, confusing his older sister.

Izuku turns his bike onto another path while Mio is trying to think of where her new little brother is taking her. She was a little worried at first, but she brushes those worries away upon knowing full well that Izuku won't do anything hurtful to her.

After another few minutes of riding on the bike, Izuku stops and shows Mio a spot where they can see a very high place where they can see almost the entire town from this height.

"Oh wow, it's amazing!" Mio amazed of this place.

"Yeah, I thought of the same thing." Izuku smiled.

"I found this place after my moms showed me the new house, I wanted to know what the town was like so I would know where to go and see what it's like compared to my old home and that's when I found this spot. I don't think anyone else knows, not that I know of anyway." Izuku explained.

"It's a really amazing view, I was hoping to bring you, Maria, and our moms here to have a picnic together." Izuku said.

"Oh, that sounds nice." Mio commented.

"I know things are a little strange right now, being brought to a new place and living together with people you just met so suddenly which may seem scary, but I can promise me, and the moms are going to do whatever we can to make you and Maria happy in life." Izuku said.

"We'll b there for the both of you, always." Izuku said, taking Mio's hand.

"Really? You promise?" Mio asked.

"Of course, what kind of brother would I be if I didn't promise anything serious like family? No matter what happens, no matter the hardships and danger that may come out way, you'll always be important in this family." Izuku smiled strongly.

Hearing those kind and strong words from her new little brother has causes her heart to skip a beat almost like she was stunned; she felt warmth in her heart.

"Believe me when I say that we won't live your side ever!" Izuku promised.

(Nighttime, Home)

"You two are leaving now?" Izuku asked shock.

"I'm very sorry, sweetie. But my agent called in discovering that he mixed up the date for the shoot, we have to start doing it now and tomorrow." Raphaeline apologized.

"The gym called me in requesting to train some of their fighters for a last-minute of Hell training session before their big match. I'm probably gonna be gone for just as long too." Sapphire informed.

"Well, I guess there's nothing that can be done when it comes to the unexpected." Izuku commented.

"Don't worry, we'll be back before you know it. It's probably just gonna be a day, two at the most depending on how it is." Sapphire roughed Izuku's hair before giving him a kiss on the forehead.

"While we're gone, you're in charge of taking care of your big sister and little sister. We're entrusting the safety of this house in your hands." Raphaeline said, giving him a kiss on the forehead too.

The two women went into their car and drove off together as Izuku waves goodbye to them, and Mio watching the two mothers leave with a silent serious look.

KO a new chapter is done and hope you all enjoy it!

Seems like Izuku has gotten to know a little more about his two new sisters on the first day of living together, and even meeting two new friends that he'll definitely see more of them once they get settle in their new school. But something tells me those girls are up to something.

Chapter Text

Heroic Spirit Unleash for Sisterly Love

"They're finally gone." Mio said to Maria who is in the living room.

"Good, now we just have to deal with the boy and we're golden." Maria sounded a little serious.

Izuku walks back into the house while hoping in his head that nothing goes wrong while they have the house to themselves, but then he notices the lights are going out suddenly.

"That's odd, could it be a power outage?" Izuku puzzled a little.

"Girls, are you both okay?" Izuku called out, but he heard no response and decided to head for the living room.

"Oh, there you girls are. I was worried that you would be scared with the lights suddenly being off." Izuku relieved to see his two sisters are alright.

"Aright, as you already know, the moms are gonna be gone from the house for a while. So, do you all have any thoughts on what to eat for dinner?" Izuku asked, offering himself to cook.

But again, no response from either of the girls almost like they're treating him like a stranger to never trust or something.

"(Something is definitely going on with these girls. I have to try and be friendly.)" Izuku thought hoped to get them to open up again.

"If you don't want any home cooking, we can always order takeouts. Maybe some nice steaming katsudon plate would smooth your tummies." Izuku tried to offer them the idea of some tasty katsudon, and maybe have some dessert after.

"Listen, Izuku…" Mio finally spoke.

"Yes?" Izuku responded.

"I have just one request." Mio said.

"Sure, depends on what that is, I can help." Izuku hoped it is something he could do.

"I want you to leave this house." Mio requested.

"Huh, leave the house? What do you want me to leave the house for?" Izuku confused on this.

Suddenly Maria holds out her hand and three glowing circles appear followed by a powerful gust of wind blew Izuku slamming him to a wall, and he fall down to the floor.

"You need to listen. Didn't you hear what Mio just said?" Maria asked sarcastically, sounding a little dark.

"That was… wind magic she just use?" Izuku whispered to himself softly as he struggles to push himself back up.

"Interesting… When a human sees magic for the first time, they usually panic and are terrified by what they've seen." Maria was impressed of how calm Izuku is being.

"I knew it, you did use magic." Izuku looked up.

"Oh my, so it would seem you're already aware of the existence of magic." Maria surprised with a grin as her body starts to glow.

"If you truly know that magic exists, then you must also know that there are other races that are not human." Maria started to transform, showing her true form.

Now Maria has slit purple eyes and small black horns on her head, dressed in a black leather revealing outfit, white leggings with light pink horizontal stripes, and black boots, as well as small black wings located near her waist.

"So, that's what you really look like. Does that mean Mio isn't human as well?" Izuku asked, looking over to Mio.

"You need to learn how to listen and be silent. You're being very disrespectful… to the future Demon Lord." Maria revealed one big thing about Mio.

Izuku's eyes widen with shock upon hearing something that he never thought to hear when his two moms told him about getting two new sisters, now finding out these two are actually demons in disguise as humans.

"So, you two have been demons this whole time. And Mio, she's the one who's going to become the Demon Lord." Izuku said, still in a little shock as he gets back up.

"That's right, and our enemies, the Clan of Gods, exist as well as what you call "heroes". I'm sure you already know those facts given how you already know of magic." Maria pointed out.

"So, what is it you two want exactly?" Izuku asked.

"Mio and I have decided that we're taking over this house to serve as our base here in the human world." Marisa revealed another thing why they're here.

"So, you two being adopted into the family was really…" Izuku started to figure out more of this.

"A ruse. You could say we're orphans, but we never wanted to be part of a weak family of humans. So, we altered both of your mothers' memories accordingly. And, now it's your turn…" Maria revealed as she held out her right hand towards Izuku.

"It's such a shame that you're really a nice boy, so let's have you become our butler and you will have no memories of your former life. We'll keep you around until we don't want you anymore." Maria decided on the fate of Izuku.

"Does that sound like a plan, Mio?" Maria asked her mistress.

"Yes. That'll do." Mio agreed.

"So, it was really a lie. That you two wanted to be part of this family." Izuku felt sad of this sudden revealing.

"Yes. I'm sorry that this has come to it, Izuku. You really did seem like a trustful guy, despite being a weak human, but we have already decided to take this house." Mio said, looking at Izuku in the eyes.

"Be grateful that we're keeping you around, but you won't be yourself." Mio stated.

"Bye-bye, little brother. It wasn't long, but it was fun while it lasted." Mio bid her farewell to Izuku.

Izuku then saw something in Mio's eyes that told him a lot more than what Mio was telling him, something that may have given him the bigger picture.

Maria flashes a bright green glow engulfing the living room with that light for a second and then Izuku just stood there in silence with his eyes being shadowed by his hair.

"Now, get out!" Maria ordered.

But Izuku doesn't move an inch from his spot, he just stands there looking emotionless like a statue which confuses the two sisters.

"Well, that's strange. I'll try it again." Maria said, maybe she'll need to put a little more of her magic.

"I'm afraid that won't work on me." Izuku said, shocking both demon girls.

"What the… What did you just say?" Mio asked.

"That kind of magic can only work on those with magical energy levels weaker than yours or to those with weaker mindsets." Izuku pointed out.

"Hold on, are you saying that a human like you is stronger than me?" Maria asked shock.

"No, you can't be! You don't strike anything off than being an average human." Maria refused to believe that.

But Izuku somehow vanished from their sight with a wind blowing past them and he reappeared right behind them.

"(The fuck just happened? Did he teleport? No, that felt more like speed!)" Maria thought shocked.

"I would advice you to stand down." Izuku said.

"You bitch! You dare to resist us?" Maria asked angrily.

"Only if you want to use force some more." Izuku answered.

"Fine then—you're going to get hurt!" Maria coated her right fist with a white magical glow and charges at Izuku.

But Izuku isn't afraid and doesn't flinch as he gets into a position like he is about to draw out a sword from the sheath, and there was a green glow for a couple of seconds and the magic from Maria's fist was sliced away.

"No, my magic! That's impossible!" Maria shocked as Mio gasp.

"It's not impossible when one belonged to the Hero Clan, such as myself!" Izuku revealed, summoning a silver gauntlet of the right arm and a large silver sword.

"No way! But the Hero Clan should be in their hidden village! So then, what are you doing here?" Mio asked.

"While normally those from the Hero Clan would stay in the hidden village until they were given a mission. However, a tragic incident and since then, my family have been exiled from the village, banished from the Hero Clan." Izuku revealed his own truth.

"What the what?!" Mio shocked.

"A banished hero!" Maria shocked as well.

"That's right, I can't tell you why, but let just say I caught in that incident." Izuku put away his sword and gauntlet.

"Hold on, you said that your family have been exiled by the Hero Clan, that would mean your mothers were also part of the Hero Clan!" Mio realized in utter shock.

"You could say that, but they're a lot more than you know." Izuku stated.

"If you want to know more about us, then you're gonna have to ask our moms when they return from their jobs. I'm still shaken up from the event that I don't wanna talk about it." Izuku grabbed his arm.

"But right now, let just get ourselves dinner together and try to make the most of it." Izuku held out his hand to the two girls.

Both Mio and Maria are very shocked to see that not only Izuku was being honest about formerly being part of the Hero Clan, but also wanting to offer them dinner like he's expecting them to stay.

"Why…?" Mio asked.

"Well, it's because you girls are angry." Izuku answered, oblivious of what she's asking about.

"No! I mean why are you still trying to be our brother even after what we tried to do to you? Mio yelled.

"We lied to you, we manipulated into getting us a house, we were even going to make you into our slave! And yet, you're just going to let all that go and still accept us as our family! Why?" Mio asked with tears coming down from her face.

Izuku can see that Mio is letting out her emotion, probably more than she realizes.

"Because it's the right thing to do." Izuku smiled.

"Not only that, but we're family. I did promise you that me and our moms are always going to be there for the both of you no matter what." Izuku explained some more.

"Damn it, you make no sense at all!" Mio clutched her hands.

"…I'm going outside for a while; I need to clear my head." Mio walked away and headed out of the house.

"And you, Maria? What are you gonna do now?" Izuku asked the younger sister.

"I, huh… I think I'm going outside with Mio." Maria answered and quickly followed Mio.

Izuku watches his two sisters leave the house and go somewhere to clear their heads about everything that has just happened to them, and Izuku feels like he needs some cleaning in his head too as he went up to his bedroom.

"Oh man, that was intense…" Izuku panted a little hard, feeling a bit exhausted.

Izuku didn't think that he would have to use that power at all, not after all these years from that tragic incident five years ago.

He can still remember that big incident that caused his family to be kicked out of the Hero Clan, as well as the monster that was there that was responsible for his dad and big brother's death.

Izuku doesn't exactly remember what happened back then as the rest of the details are all fuzzy, but he does remember that he somehow took the powerful sword and everyone at the village all hated him for what happened afterward.

"(I didn't think I would have to bring out that sword again.)" Izuku thought looked at his hand, shaking from the big fear within.

"(Easy Izuku, that was all in the past. In the past.)" Izuku thought took some deep breathing and calms himself down to stop the shaking.

"But even so, the past will always be something we can never forget." Izuku sighed.

"I better call mom and mother to let them know about what happened?" Izuku picked up his phone and dialed to mom-Sapphire's phone number.

(With Sapphire and Raphaeline)

"I see, figured those two would try and pull something like manipulating us. As if their level of magic would work on us." Sapphire said.

She and Raphaeline are at a little convenient store to pick up a few snacks for themselves for the extra work hours, they also got gas from the gas station too.

"So, did you two already knew about Mio calling herself a Demon Lord?" Izuku asked.

"Ha! So, she's already trying to snatch up the big title! Gotta say, that's some big shoes to fill if she ever wants to be every bit of a Demon Lord her dad ever was." Sapphire laughed a little.

"Her dad? You mean her dad is the Demon Lord?" Izuku asked surprise.

"Before we get to that, you should know that the Hero Clan Village have been watching them and we feared those guys would do something awful to them if we didn't take them in." Raphaeline mentioned.

"What? But why would the village try going after them?" Izuku shocked.

"It's because Mio's dad wasn't just any Demon Lord, he was the Strongest Demon Lord named Wilbert." Sapphire revealed.

"Wilbert was someone very close to me, your mother, and your father during our time together. Believe or not, Wilbert was a very peaceful Demon Lord who got the fucking war-demons to settle down and even stopping the long-ass war with Hero Clan with just his immense power only." Sapphire explained this.

"The two sides became together for a truce, hoping that it would bring peace between humans and demons, but unfortunately, the war-demons were not very fond of the idea and wanted to take the throne by force." Raphaeline mentioned.

"Wilbert was very worried for his child to be caught in the problems that he unintentionally created, so he had two fateful servants take the child to be raise in the human world and that child is Mio." Raphaeline mentioned.

"If that's the case, then why did they try doing what they did?" Izuku asked.

"Because… Wilbert died, around a year ago." Sapphire revealed sadly.

(With Mio and Maria)

The two sisters are standing at the special spot where Izuku took Mio on their outing together.

"I'm sorry, Maria. I just wanted to see this…" Mio apologized.

"Izuku, he still wants us to live together despite knowing that we're demons and him being from a Hero Clan." Mio said.

"He is certainly full of surprises. Maybe… Maybe we should stay with him, things could really turn out better for us." Maria believed.

"Maybe, but I don't want others to be hurt because of me." Mio said, but then she senses something that is covering the entire area.

"It's Warding Magic!" Mio alerted.

"It's the enemy!" Maria cursed, just their luck.

(With Izuku)

"So, the current Demon Lord who took the throne wanted to take Mio by force because she has the destructive power that was passed on to her by Wilbert, and that was also the time when her true nature was revealed. I'm sure you can imagine the shocked on her face when she learned the truth." Sapphire explained.

"Her powers haven't fully awakened yet; she might end up being dead if nothing helps her. But more than that, she is just a little girl who lost a happy family, and she deserves happiness as I'm sure that's what Wilbert wants for her." Raphaeline said sounding sad.

"Which is why you took them in, because they would be safe while trying to help them find peace." Izuku rushed down the stairs.

"That's right, we owe Wilbert that much for trying to do so much good. So, please Izuku, protect them." Raphaeline pleased.

"Don't worry, I will!" Izuku promised as he burst out of the door.

"So, you're his son, huh? You don't look much from being Jin's kid." A woman said, standing at the gate.

"Huh, Jin? That's my father's name. How do you know him?" Izuku asked.

"My name is Ghislaine Dedoldia, and I'm here as a promise to your father." Ghislaine answered.

Ghislaine is a tall muscular woman with chocolate skin, brown eye with a white eyepatch over the right eye, and long gray hair that reaches down the midway of her back. She wears a black leather jacker with fur on the front part though not on her shoulders showing her well-toned abbs with a large scar on the belly, a small red bikini on her large breasts, pale green pants with the front open a little showing her black underwear and strings on her hips, and brown sandal-like shoes. She also wears a red collar on her neck. She got cat-like ears on her head and a long tail that is like tigers, and a gold ring on the tail too. Breasts sizes: I-cup.

"Now, are we going to rescue those two girls or what?" Ghislaine asked.

KO a new chapter is done and hope you all enjoy it!

Chapter Text

Saving Demonic Sisters with Family Comfort

Izuku, accompanied by Ghislaine who just showed up out of nowhere and claims to know his father as well, is running through the streets trying to find Mio and Maria while trying to think where they could be right now.

"(Think, Izuku. Think, there has to be a place the girls went to that I know of.)" Izuku thought tried to think of something.

But then his mind went into a memory, to the moment where Izuku and Mio went to the spot he took her to for that great view of the city. And then it clicks in his head, that's where they are.

"So, where do we start looking?" Ghislaine asked.

"Don't worry, this search will be short because I already have an idea on where they are right now." Izuku said before running faster than before.

"Dang, this kid is already getting ahead of me and all that speed is for finding two girls. He really does have a big heart, huh, Jin?" Ghislaine grinned, now seeing the man she once knew into that little boy.

(With Mio and Maria)

"Take this!" Mio unleashed a lightning magic attack at a monster lion with purple sharp manes destroying it.

Maria killed another monster lion with one punch in the face causing it to literally blow up.

"Is that all you got?" Maria asked mockingly as she lands back on the ground with a smirk.

"Keep struggling uselessly like that. You're just making me more hot and bothered!" Maria smirked, wanting to waste these monsters for wasting their time.

"That's it. This is the end." Mio said, then she senses danger coming at her from behind.

That danger is a creature that resembles the Grimm Reaper with a sharp scythe that was going to be used to cut Mio down.

"Time to die a hundred times!" Mio quickly turned around and fired a magic blast that destroyed the Reaper creature.

"Are you okay, Mio? Are you hurt?" Maria asked, running up to her mistress.

"(They've finally taken action. Fine. If you want a fight, I'll give you one.)" Mio thought decided to show these fuckers who they're messing with.

"Mio!" Maria shouted because a dark mist suddenly appeared out of nowhere when they only had their guards down for a second or two.

The black mist creature attacks with a lightning magic strike at Mio sending her fly through the trees and over edge where she would fall to her death from such a height.

"(No… I can't die here…)" Mio thought feared that this could be the end.

(Flashback)

The scene shows Mio on her knees in total shock of horror to see both her parents, the ones who raised her throughout her entire life, were killed right in front of her eyes by a man with a sword that is stained with their blood on it.

"Daddy… Mommy…" Mio cried.

There was also fire everywhere, the flames burning the house from the inside.

(Flashback End)

Izuku is running on the path to the special viewing spot until he looks up to see Mio is falling.

"Mio!" Izuku shouted.

Even though he had only known these girls for a short time, they are precious to him because how they became a family together and growing closer together as a family too, and he promise to never let anything bad happen to them as he would face them head on.

"Miss Ghislaine, throw me!" Izuku requested the cat woman.

"You can drop the formality, not really my thing." Ghislaine said, then grab him by the back of the shirt.

"Just try not to die on me!" Ghislaine said before she threw him high towards Mio.

"Mio!" Izuku shouted again, this time Mio heard that.

"Izuku?" Mio was shocked to see him here and coming to rescue her too.

Izuku caught her in his arms and was able to land on the ground with his feet though he slips and fell on his butt, but they still managed to land safely.

"Hey! Watch out!" Maria warned.

The Reaper creature came flying at them to kill that Mio girl as it was order to, but it never got close to her as Izuku stood in its way.

"(Please, let me use this sword… To protect the ones, I love! To never lose them again!)" Izuku thought shouted from within his soul and he brought out the sword he used earlier to destroy the Reaper creature.

"That's some power he got there." Ghislaine commented.

"I heard about what happened him and his family in that Hero Clan village five years ago, involve with a big explosion and the Tojo family were expelled from the Hero Clan." Ghislaine remembered hearing about that years ago.

"Mio! Are you okay? Are you hurt anywhere?" Izuku asked, going over and checking on Mio's body.

"Huh, yeah, I'm okay." Mio answered though was still surprised that Izuku came all the way here for her and Maria.

"That's good, I would feel really bad if anything were to happen to my family. I'm so glad you two are safe." Izuku smiled honestly, this shocks Mio and made her heart skip a beat.

"I don't believe it, that guy really does care about us even though we're demons and I'm also surprised to see there's a cat beast race here too." Maria said, looking down to see all of this.

Maria's thoughts on this were interrupted when she heard a roar coming from the woods.

"Shit, probably more of those monsters to kill Mio. Not if I can help it!" Maria stormed off to fight the remaining monsters here.

However, when she arrives at the spot where the roar was coming from, she stop in shock to see that the monsters were already defeated by two figures standing in the middle though their faces are head to see with one having their back turn and the other is wearing a helmet concealing the upper half of their face, but she can tell these two are women.

"(What just happened here? Did those two get out the monsters just now?)" Maria thought puzzled.

"Do not worry, we're not here to hurt you nor your family." The helmet woman said.

"We're here because these monsters dare to try causing trouble in our territory, we already know that you and your family are no threat to us nor the good people of this town. Have a good night." The other woman assured.

"Wait! Who are you?" Maria asked while trying to catch them.

But the two mysterious women vanished from the spot in a slight bright white glow like they just teleported.

"Teleportation magic? I won't be able to follow them." Maria cursed.

"Maria, are you okay?" Izuku called out.

"Guess I can worry about those two later. I have a big brother to ease." Maria sighed, smiling.

(Tojo Home)

After returning home, Mio went upstairs to take a bath while the rest are hanging around in the living room as Izuku serve a drink for the two.

"No booze?" Ghislaine asked, sitting on the couch.

"I rather not have any go drunken when we're having a peaceful moment. But if you still want some, you'll have to ask Mom-Sapphire when she gets back." Izuku said before going to sit at the table with Maria.

"Izuku, I just wanna say thank you for saving from those demonic beasts." Maria thanked.

"You're welcome, just doing what a big brother can do for both his big and little sister." Izuku smiled.

"You still treat us so kindly even though we both deceived you and your mothers; just what kind of human being are you?" Maria asked curiously.

"You could say I'm a special case, maybe a bit more that separates me from the Hero Clan that banished my family." Izuku said.

"(A bunch of fuckers, they are.)" Ghislaine thought angered, blowing from her nose like an angry bull.

"So, I had a talk with my moms before coming to you girls and they told me about the situation that you two are in with Mio being the daughter of a former Demon Lord and you on the run with her." Izuku revealed.

Maria gasp upon hearing this, that she and Mio were the ones being deceived by the two women they had thought they brainwashed into taking us in.

"I see… So, Sapphire and Raphaeline already knew about us from the start." Maria sighed. Now realizing they never had a chance against them.

"Normally, any fuckers that tried to do anything bad to those women then they would show no mercy like sending them to Hell." Ghislaine mentioned before drinking her juice.

"But don't worry, my moms can see that you two are innocent through this whole ordeal." Izuku promised, not wanting Maria to feel scared.

"I have to say, this is actually the first time I've ever met people who have been banished from the Hero Clan. You must've really fucked up if they banished their own." Maria admitted.

"You could say that…" Izuku looked down with his face looking sad and dark, the memories of that day still haunts him today and it hurts every time he thinks about it.

Maria could see that Izuku looks really hurt when mentioning his past with the Hero Clan and knew it was something he doesn't like to talk about it, so she decided to drop the subject until he was ready to talk about it himself.

"It's okay, take as much time as you need before talking about your past." Maria said with her cute smile.

"Thank you." Izuku nodded, glad to see that Maria is understandable for this.

"Ghislaine, you mentioned that you also knew my dad. Is that true?" Izuku asked.

"I'm telling the truth. Why, do you not believe me?" Ghislaine asked with a slight glare.

"No, no, I believe you! I just want to know how you know him and how the two of you were to each other." Izuku clarified the question.

"Oh, okay." Ghislaine nodded.

"I used to live with my village years ago when I was little until I ended up getting lost in a big forest when we went out camping for survival training, I had no idea where I was going though, I kept doing what I can to survive even eating poop." Ghislaine explained.

"Ew! Who in the fucking right mind would even go down to even eat poop?!" Maria was grossed out from hearing that.

"(I'm going to pretend I didn't hear that.)" Izuku thought exclaimed.

"After many days, months, I had a run-in with Jin was out in the woods for his own training." Ghislaine mentioned.

(Flashback)

Young Ghislaine, about in her early teen years is seen running through the woods on all four then stop when she stumbles upon the boy named Jin who was surprised to see a beast girl like her.

"I just attacked him on sight, but I soon realize who outclassed I was in strength and such." Ghislaine said.

Ghislaine charges at Jin to slash him with her claws only for the young man didn't look scared and everything happened so fast that Ghislaine is on her back against the ground and Jin standing over her and try to offer her a hand of friendship.

However, Ghislaine growls with a fierce glare.

(Flashback End)

"I kept on attacking the guy about a dozen times and he would beat me down every single time, that's when I knew he was the kind of strong man I wanna follow." Ghislaine smiled.

"I guess that's one way to make new friends." Izuku commented.

"So, he helped me get back home and he made a powerful impression with the chief of my tribe, so we kept in touch with each other and even going on several adventures together including meeting those two moms of yours." Ghislaine remembered those good and exciting times.

"I heard about what happened, and I'm sorry for your lost." Ghislaine said.

"Yeah, there was also the part about the promise you made to my father." Izuku recalled that part before going out to find Mio and Maria back then.

"Your father had a strong feeling that something bad is going to happen to himself and his oldest son, leaving you behind to handle the struggle on your own. So, he visited me to make a promise if anything were to happen to him, I would go become your knight or something like that to help protect you and anything else you might need." Ghislaine explained the promise.

"(Dad, even in death, you're always thinking about us.)" Izuku thought smiled.

"Of course, he told me I can wait until the right time come to me and then I would go to you. So, here I am." Ghislaine finished her story.

"I can tell you're a really strong cat Beast Race, didn't think I meet one among a human town." Maria said to the cat lady.

"It's not like there are rules in my tribe that we can't go to a human town and live there, I'm just living the moment." Ghislaine shrugged.

"Well, when my moms come back, we'll talk about you living here and see if we can help you get settle in." Izuku said.

"Thanks." Ghislaine smiled.

"Hey, is Mio doing alright?" Izuku asked, feeling a bit concern Mio as it has been a while since she has taken the bath.

"Of course, she just likes to take long baths. Let's just hope that helped her to calm down a little." Maria answered.

"What about you? Are you okay after facing off some monsters?" Izuku asked.

"Don't worry, I'm very strong in my own way too. Those monsters didn't stand a chance against my fists." Maria bragged with a grin.

"Oh, I heard about Succubus having develop their own fighting strength over the years and now you got me curious." Ghislaine said with her ears twitching with excitement.

Maria doesn't know why, but she suddenly feels like she made a big mistake when telling Izuku about her strength.

"I'll just go to my room for a while." Mio said as she leaves.

"I think you scared her." Izuku pointed out.

"Whatever, you got any snacks?" Ghislaine asked, stretching her arms up a little making her breasts bounce a bit.

Izuku gasps with his face turning red and looks around as he wonders if Ghislaine is really okay going around dressing up like that.

(With Mio)

Mio finally finish her bath and came out drying herself with a towel, her mind then went back to how that Reaper creature caught her off guard and sent her flying.

"(Maria taught me how to use my magic for six months, and yet… If it weren't for him… I would be dead.)" Mio thought felt that fear when she was almost killed.

"Thinking about it now… makes me frightened. No… I'm no good." Mio feared that she's useless.

Then she heard knocking coming from outside.

"Mio, are you okay in there?" Izuku asked.

"Oh, Izuku, I'm okay. Just finish with my shower." Mio answered.

"That's good, I was worried that you end up becoming dizzy and fell on the floor." Izuku was relieved to hear that.

"Hey, just letting you know that Ghislaine, the cat woman who came home with us, is going to be living with us since she promised my dad." Izuku informed.

"Oh, I see." Mio said, but more focus on Izuku.

"Tomorrow, we can go hang out at the special spot and may have a picnic for lunch." Izuku offered.

"Are you stupid?" Mio asked which confused Izuku.

"How can you be so calm and casual when we tried to get rid of you and two of your moms from the house. We even tried to use magic to manipulate your memories and take your…" Mio suddenly felt something is wrong with her as the eyes look blurry before falling on the floor.

"Mio, is everything okay in there?" Izuku asked as he heard a thump sound. He doesn't like going in the bathroom and a girl is doing her private thing, but in the case is an emergency.

Izuku braces himself as he goes inside the bathroom to see that Mio just collapsed on the floor.

"Mio! Don't worry, I'm sure you're fine. Maybe I need to get the first-aid kit!" Izuku panicked as he picks her up.

"Seriously, how do you have such a big heart?" Mio asked, looking up at him.

"You could say it runs in the family." Izuku chuckled.

KO a new chapter is done and hope you all enjoy it!

Izuku was able to save his sisters from danger, and it looks like there is a mysterious duo who may already know about the family. Looks like Mio is still trying to adjust with Izuku being so kind to him and maybe feeling something else that strong towards him, that could lead to a certain ritual.

Chapter Text

Start of the Love Contract in the Family

"Now, we just need to give you a checkup to see if anything is wrong with you." Izuku said.

"Oh my…" Maria showed herself leaning on the wall just when Izuku and Mio exited the bathroom.

"It looks like you two are starting to get along pretty well." Maria grinned.

"What?! That's not true at all! What makes you say that?" Mio asked in shock, trying to play it off like nothing had happened between them.

"Besides the fact that Izuku is carrying you in his arms, it's written all over your face. Izuku is a pretty strong guy too!" Maria complimented.

"I'm not sure if I'm really that strong." Izuku proclaimed, a bit nervous with his power.

"Don't be modest. You negated my magic pretty effectively, didn't you?" Maria pointed out the moment in the living room earlier before she and Mio left the house for a while.

"Yeah, I was able to do that, but that was more of a lucky thing that I was able to do it at all since I've haven't really use it much in the years since my family's banishment." Izuku stated.

"Really? It looked like you know what you were doing and you're saying that it was pure luck that it worked out for you? What kind of technique was that?" Maria asked. Shocked to hear that Izuku hasn't used that in years.

"It's not really a technique. Just something that happened…" Izuku looked down, looking sad but he shook it off remembering that he has Mio in his arms.

"Anyway, I'm gong to take Mio to her room and check on her condition." Izuku said before walking away.

Sometime later, Mio is in her bedroom alone in nothing but the towel from the bathroom deep in her thoughts about Izuku with his kindness and the words he said after her failed attempt on taking over this house.

"Because it's the right thing to do. Not only that, but we're family. I did promise you that me and our moms are always going to be there for the both of you no matter what." Izuku's words echoed in her head.

"Family, I guess he's right." Mio started to see that now, the feelings of family when Izuku and the two moms welcomed her and Maria into the family.

Mio goes to a drawer to take out picture frame with the cracked glass and the picture of herself with her adopted parents, all three of them smiling together from the days they were together and unaware of her demon heritage for most of her life.

And she can still remember how her parents died with the father losing both his arms and exploding into flames and the mother being burned alive.

Mio whimpers of the very sad, tragic memories of that day when she lost everything she knew and the two most important people in her life, gone forever.

Her sad thoughts on that day were interrupted when she heard knocking on her door.

"Um. Uh, yes?" Mio asked as she placed the photo frame down on the bed, and the open door revealing that it's Maria.

"How are you feeling? Are you doing a little bit better now?" Maria asked concern.

"Yeah, I'm fine." Mio answered, assuring Maria that she is doing fine right now.

"Oh, good. Would you like some water?" Maria offered to get her some refreshment.

"No thanks, I'm really okay." Mio said.

It does look like Mio is doing okay right now, but Maria could always tell that something is bothering her and got the answer when she saw the photo frame of Mio's former family which is still fresh in her mind.

Mio gasp softly when Maria saw the photo knowing that she couldn't hide what she's really feeling now.

"Do you think… he really intends for us to be a family?" Mio asked as she looks at the old family photo.

Maria didn't say anything at first but instead showed her something on top of the old photo with a new one that shows of her and Mio together with Izuku and the moms, Sapphire and Raphaeline smiling.

"What's this?" Mio asked.

"Izuku printed out a copy for us to have." Maria answered, then started asking a question for Mio to answer.

"Do you think Sapphire ad Raphaeline and Izuku were just faking it, like we were all one big happy family?" Maria asked, Mio shook her head for no as an answer.

"Then why don't we just accept their kindness?" Maria suggested, believing this family is really something where they belong.

"The truth is, right now, you need every ally that you can get." Maria pointed that out as well.

Mio couldn't argue with that after escaping death from the attacker and Izuku showing so much kindness throughout the whole day and she can already tell that he is a wonderful boy who would go through many lengths to protect the ones he loves and do his best to make them feel happy.

She fully knows that everything is going to be alright for them, being in this big family that has started for them and perhaps helping her more than she realizes when Mio found out the truth back then.

"(Izuku, I want to be closer to you now. For us to be a family.)" Mio thought smiled at the photo.

"Great! Then everything's settled!" Maria smiled. Now she can bring out her plan.

"I've got a proposal! A very important proposal in the regards to our future!" Maria said with a grin.

"Proposal?" Mio wondered what Maria has in mind for this proposal and would it also have any effect on Izuku too.

"(Bingo!)" Maria thought smirked.

(Living Room)

Maria has called Izuku over into the living room without telling him the reason why he needed to come down to the living room and why she said to him that it was important, but he figured it wasn't a big deal.

Now he should've known that Maria was up to something when he is now standing on top of a gold magic circle with Mio as well while Ghislaine is just watching this from the sideline sitting on the couch.

"So, what exactly am I looking at?" Ghislaine asked.

"The Master-Servant pact magic." Maria grinned.

"I'm sorry, the what now?" Izuku asked, feeling very nervous about whatever is about to happen.

"Izuku, I would like for you and Mio to form a Master-Servant Testament." Maria requested.

"This is very confusing and so sudden at the same time! Why do me and Mio have to perform this pact?" Izuku asked.

"Oh, it's just a formality. Those whose souls are bound by a pact are able to sense each other better. I think that's something we should take full advantage of, so you'll be able to stay in touch and attuned to Mio's whereabouts." Maria explained the purpose of this ritual.

"Really? Like becoming a living GPS? That would be better in case our modern tech malfunction and probably respond better if she's caught in an enemy's trap." Izuku started to see that in those sorts of ways.

"See, now you're seeing what I'm getting at. I am so glad you could understand with that big head of yours." Maria leaned closer to Izuku, making him blush a little.

"But why are we doing this now?" Izuku asked.

"This magic can only be used on the night of a full moon. Tonight just happens to be a full moon, and we can't afford to miss this chance!" Maria pointed out.

"Oh yeah, there is definitely a full moon." Ghislaine nodded, remembering seeing the moon on her way here.

"(Oh man, this is something I can't just walk away from, can I?)" Izuku thought gulped.

"Huh, Mio, are you really okay with this? Forging a pact with each other?" Izuku asked, wanting to hear Mio's answer if she is really okay with doing this Master-Servant pact.

"Um… Yeah, sure, I'm fine with it, I guess. As long as… you wanna do it too." Mio looked at him with nervous and pleading eyes.

"Looks like she wants you to find her." Ghislaine believed.

"Well, if that's the case then I guess we're really doing it." Izuku decided to go with it.

"Right. So, we'll be able to find each other." Mio said, getting everything she just heard down.

"Great! Then it's all settled!" Maria clapped her hands together.

"This will be the first time you've ever cast magic, and I'll be right here to support you." Maria said, Mio nods with a smile.

"So, how does this pact work, other than just standing on top of the golden magic circle." Ghislaine asked.

"First, a magic circle will be formed on her hand. Then the pact will be complete once Izuku kiss it." Maria answered.

"Sounds simple enough, but me being the slave still feels weird and something else that I can't describe." Izuku commented.

Izuku felt something strange coming from his right hand and saw a glowing green magic circle appearing on the back of his right hand.

"Uh, Maria, there's a magic circle showing up on my hand. Is that suppose to happen?" Izuku asked.

Maria smiles sinisterly as her plan is coming together, something she had been hoping for to happen.

"Maria! What's the meaning of this?!" Mio gasped and demanded to know as she shakes Maria.

"Uh, wow! Well, that's pretty strange. I must have made a mistake—"

"Now what are we gonna do?!" Mio asked in fear and shaking Maria again.

"Let's just focus in on the goal to be aware of each other's whereabouts! So, if you will please, Mio… you can go ahead and kiss Izuku's hand now." Maria said, trying to play this off.

"You have got to be kidding! If you make me do that, then I'm the one who'll end up being his slave!" Mio pointed out in swear making Maria sweat nervously.

"Let's calm down and try to think this through." Izuku said, but he notices the magic circle on his hand is starting to fade.

"Huh, excuse me?" Izuku tried to get their attention.

"Do you mind? This is between us." Mio said.

"But this magic circle on my hand is fading." Izuku alerted.

"(Fuck no! This needs to happen now!)" Maria thought refused to let this opportunity go to waste.

"You better hurry up, Mio, before it's too late! Go smooch it!" Maria encouraged Mio to go kiss that hand and become Izuku's slave.

"But… I don't know—" Mio hesitated to go through with this when it was supposed to be the other way around.

"He can be released on the net full moon!" Maria pointed out.

"That's a whole month away. I don't know…" Mio still hesitated to do it.

"I'm sure we can think of something… Oh wait, it already disappeared." Izuku noticed the magic circle on his backhand is completely gone.

Maria whimpered in horror that her plan has been foiled by Mio's hesitation and fell onto her knees, if only she could've done this a little sooner then she could have had a little more time to make Mio kiss the hand like she wanted her to.

Mio sign in relief that she doesn't have to go through kissing his hand and becoming his slave, that would've been very awkward for her that's for sure.

But suddenly something strange happens to Mio as a magic crest appears around her neck like a magic collar of some sort.

"Hey! Wh-What's this?" Mio asked in shock, starting to feel something strange happening to her.

She whimpers as her body shakes from something that is happening to her on the inside, like there is a force that is starting to grow bigger and bigger with this unusual feeling that is suddenly making her feel hot but not in a way that is like being out in the sun on the hottest day and it's brutal as this hot feeling is different.

"No way… No!" Mio feared of what might be happening to her as she fell on her knees.

"Mio! Is everything okay? You look like you're in pain!" Izuku worried for Mio.

Izuku walked over to her to see if there is anything wrong with Mio, but the moment his hand touches her shoulder, Mio suddenly moans loud in shock.

"Okay, I can see that is not something I was told about!" Izuku gasped.

"Oh no! The curse is already taking effect!" Maria realized.

"Curse! What curse are you talking about?!" Izuku was shocked to hear that this is some kind of curse.

"Kid, I think you better tell us what is going on with Mio or else you might be waking up with thumbs." Ghislaine threatened with her red sword to her throat.

Maria chuckles nervously while fearing for her life on the inside, guess now would be a good time to explain what is going on with Mio and what Izuku has to do.

"The main purpose of a Master-Servant pact is to maintain the subordinate's loyalty. So, when the subordinate takes rebellious or traitorous action, the curse activates. Since Mio refused the kiss of loyalty, then most likely…" Maria paused for them to figure out.

"This curse is making her moan like she's in heat for lust." Ghislaine guessed.

"What? That's the curse right now?!" Izuku gasped.

"Yes, and despite my appearance, I'm a succubus." Maria revealed her true nature with her cheeks blushing.

"Oh, a succubus, that make sense." Izuku nodded and instantly went into complete shock. "You're WHAAAT?!"

"Are you seriously telling me that you're one of those lewd female demons that likes to go get any men they seen and do lots of fucking lewd things with them?!" Izuku asked with his face turning red.

"Huh, so you really didn't know this whole time. I already knew from the smell." Ghislaine tapped her nose, stating that she has a strong sense of smell to know what race a person is.

"How was I supposed to know she's a succubus?" Izuku asked.

"Well, what you said, it's slightly different than that. I sorta used my own magic in the pact, so Mio's suffering a succubus's curse." Maria began explaining while Mio is moaning erotically more.

"You mean you cause this on purpose?!" Izuku exclaimed.

"In other words, powerful aphrodisiac effects. It's a shame." Maria said.

"So, you wanted to have Mio feel pleasure but not with the curse." Ghislaine figured that out.

"How could you?!" Izuku yelled in worry at Maria.

"Help… You gotta try… Please help… There must be something you can do." Mio begged, struggling to keep herself down only for the arouse feeling to grow more.

"Please tell me there is a way to fix this?" Izuku asked.

"Not a problem. Rest assured. The curse is alleviated when the master makes the servant submit." Maria said.

"I have to make Mio submit to me? How?" Izuku was confused.

"That part' simple. All you have to do is touch Mio." Maria answered.

"Touch her? You mean…?!" Izuku gasped upon realizing what Maria meant by having him to touch Mio.

"Right now, the aphrodisiac effects of the curse are making her senses hypersensitive. She's never felt such pleasure. So, if you touch her for a while, she should obediently swear her loyalty to you by her own free will." Maria explained the best way to help ease the curse on Mio.

"Hey! What do you think you're saying?!" Mio asked in shock. This sounds like Izuku is going to do something to make her feel more than what she's already experiencing.

"It's all right. Just try and bear it a little bit longer. I'll have Izuku come and relieve it for you soon." Maria promised.

"It's not like I want to watch your expression when Izuku brings you to the peak of excitement and you just can't take anymore." Maria grinned.

"You're making a face that says exactly what you want." Izuku pointed it out, but Maria chooses to ignore that.

"Well, Izuku, go ahead! Please relieve Mio by touching her in her embarrassing places." Maria gestured to Mio's breasts.

"So, I have to t-t-touch her anywhere to help stop the curse?" Izuku asked, just wanted to make sure.

"You can. However, the longer you take, the more her mind and body will suffer. Mio will ascend to Heaven in both senses of the phrase!" Maria answered while Mio lets out some more moans again.

"I thought devils go to Hell when they die." Ghislaine said.

"Oh man, I can't believe something like this is really happening and I'm the only one who can save Mio…" Izuku gulped with his hands shaking, but he stops them with a clutch knowing what he has to do.

KO a new chapter is done and hope you all enjoy it!

Just when the family were about to have the first night of peace together, Maria decided to do a little magic pact to have Mio become Izuku's slave and suddenly got hit by the curse which Izuku will have to get really physical with Mio in order to save her from the extreme pleasure.

Chapter Text

Forming the Deeper and Physical Connections

"(Okay, so to recap. I'm about to form a master-servant contract with one of my new foster sisters after saving them from an ambush, but now I just found myself having to actually do much more than touching her.)" Izuku thought quickly recounted on what is happening right now.

"Well, Izuku, if your personal preference is to tease her bit-by-bit, I guess that works too. I prefer that as well, myself." Maria smiled sexually.

"You better get to it now or else that Succubus is going to keep on talking like that for a long while." Ghislaine advised Izuku to get on with the contract.

"Oh man…" Izuku gulped as he moves closer to Mio despite his head screaming in fear.

"No. Just… stay back you idiot… If you do anything weird, I'll kill you a hundred times." Mio threatened but the arousing heat feeling in her body is growing more just now.

"I'm really sorry about this, Mio. I wish there were another way, but I promise I'll try to finish this as quickly as possible." Izuku kneeled down and move one hand towards her.

He hopes that this heated feeling that is making Mio feel so sexually from the inside wouldn't have caused her body to be very sensitive to a simple touch, but he was proven wrong when he grabs her arm and she moans even louder.

"AAAAHH?! I only touched her gently!" Izuku panicked.

"You've got to do this, Izuku! It's for Mio's benefit! It's all for her!" Maria encouraged her new brother to keep going.

"…How did I get myself into this?" Izuku asked himself, feeling really nervous and scared a bit.

Izuku started moving his hands around Mio's body on the waist level first causing her to moan some more, he moves up all the way to the chest where he lay his hands on a girl's breasts for the first time in his life and Mio responded more than ever.

"Sounds like you got something." Ghislaine said.

"Yes. By the sound of it, I think you did it. You found Mio's weak spot." Maria grinned; things are now really getting interesting.

(Lemon/Sex Alert: Scroll Down if You're Younger than 16 to Skip it)

Izuku looked more worry than before now that he knows where to place his hands on her body, yet his inner manly instincts are telling him that he must see this through to the end and moved his hands toward the breasts again.

"(Oh no… Wh-What do I do…? At this rate… Brother…)" Mio thought panted, trying to move away but her body refuses to listen.

Then Izuku's hand landed right on her breast.

"No! Not there! No!" Mio gasped, feeling more of the unbearable arouse unlike before. "Izuku! It's more than I can take." She moaned.

Izuku begins groping her breasts moving them in circles while squeezing to feel his fingers sinking into her flesh a bit, this movement causes Mio to moan like crazy from the pleasure that is slowly taking over her body and the magic circle under them turns pink.

Mio had never felt anything like this before, it's like something that came out from a very erotic romance movie or a book, either way, she was not prepared for this when she agreed to form a contract with Izuku.

"No… I can't… I don't think I can do this!" Mio tried to refuse.

"But you have to, Mio. This curse happened because you rejected the Master-Servant pact. If you don't swear your loyalty to Izuku, that feeling won't go away." Maria explained.

"(I wonder if the curse is effecting me too because my body is feeling pretty weird right now.)" Ghislaine thought wondered, feeling her body a little warmer than usual and blushing.

"This boy right in front of you is your new master. Swear your obedience to him." Maria instructed.

"My master… Obedience?" Mio panted, her vision started to get a bit blurry.

"(Izuku… is my… new master…)" Mio thought almost had the idea of letting herself become a pawn for Izuku. To let him do whatever he wants to her, to feel him onto her body and more, but she quickly shook the idea.

"No, I can't!" Mio still refused, making Maria sigh.

"Looks like she's still trying to fight back." Ghislaine pointed out.

"Izuku, you have to fondle Mio's breasts again, all right." Maria said, causing the two to gasp in shock.

"Again? Does that mean… I'll have to go a little harder this time?" Izuku asked, with his face turning a little red.

"That's right. It appears that we won't be able to relieve Mio from the curse if you keep holding back, Izuku." Maria giggled.

"I-If I really have to do this…" Izuku braced himself for more of the breasts fondling.

"Wait. No." Mio begged.

Izuku place his hands on her waist then moving them up to her stomach and her breasts under the skirt, his hands go under the shirt and moving them up which got Mio to be really nervous.

"Hey! Little Brother, don't!" Mio begged, suddenly calling him little brother causes Izuku to pause in shock, and Mio was shocked on what she just said.

"(Wait, why did I…?)" Mio thought wondered why she suddenly called him brother, but a realization soon came to her.

"(I see… I guess I actually wanted to call him that.)" Mio thought felt this way deep down, but this is still so embarrassing to her.

"J-Just hang on a little longer, it'll b-be over soon." Izuku said while trying to keep himself calm as possible.

Mio was surprised that Izuku is still willing to keep on going with the contract ritual, and she gasp when her shift was lifted leaving her boobs exposed for his eyes to gaze on and making him blush a little more and Mio closed her eyes and looking away not wanting to see this.

"Don't look away, Mio." Maria turned Mio's head back to Izuku. "You need to be aware of everything… that's about to happen to you." She said.

And so, Izuku gropes onto Mio's breasts fully feeling the flesh of a girl's round chest in his hands that is making him feel arouse on the inside with some moving around and squeezing them causes Mio to moan even more and feel extra crazy from the pleasure.

"No… No, please! I can't take it!" Mio begged for this to stop, but her plead was deaf to Izuku.

"(I can't believe this is really happening! I'm really groping a woman, and I can't stop myself!)" Izuku thought panted, feeling his body moving by instinct to grope his new sister even more.

Izuku continues groping Mio's breasts and ignoring her please to stop as this sensation is too much for her to bear, each second from these intense feelings grew bigger and bigger making her feel that she released something from her private part and this groping session is not stopping.

Izuku even went for kissing Mio on the neck, just on instinct, to make her feel even more pleasure with some louder moaning sounds coming out of her mouth.

Maria and Ghislaine are both watching the display of a man having his ways with a young woman that is making them feel hot on the inside.

The young man of the house continues groping the breasts from different positions and Mio couldn't fight back against him because her body wants to feel more of it. The pleasure of her breasts being squeezed like this is causing her to release more which is really embarrassing to her, yet she felt enjoyment from it.

"Izuku… Izuku… Izuku!" Mio screamed his name.

(Lemon/Sex End)

Now Mio is resting on the couch with a blanket over her body, feeling really exhausted from having to go through that whole ritual for what felt like almost a lifetime.

"Damn, girl. You really made a mess on the floor back there." Ghislaine commented.

"Yes, our Mio went nine times! So amazing! She held out longer than expected." Maria smiled proudly, and still blushing.

"Say, kid. If you already knew about the curse, then why didn't you say anything about it?" Ghislaine asked curiously.

"Yeah, I have been wondering about that too." Izuku said.

"I was afraid if you knew, you wouldn't cooperate, and I didn't want you to change your mind." Maria explained.

"I see, I guess I would have turn down the whole pact idea if you told me right away, but this pact let me know if anything happens to Mio. So, I would still go for it." Izuku said.

"Really? So, you're not mad at me?" Maria asked in surprise.

"No, you had your reason. But there is someone who is really mad at you." Izuku warned.

Then Mio, having recovered mostly, strongly grabs Maria's head with a tight squeeze making the younger sister shake in fear.

"Maria. You and I need to talk." Mio demanded.

"You're hurting me, Mio, my head! Wait! That hurts! I didn't mean to do it! Stop it!" Maria begged, trying to escape only to fail in vain.

"Oh man, I did not expect my first night with my new sisters to go like that." Izuku signed as he sat on the couch.

"Bet you weren't expecting to get any siblings at all." Ghislaine guessed.

"No, but you know what… I'm really grateful, we all have gone through shit moments in life that took away the family we had, but now we can band together to live a better life." Izuku smiled.

"But you do know that more demonic shit and other things will be coming after Mio because of her position, right? This kind of night won't be the last." Ghislaine pointed out more danger is coming.

"I know, which is why I have to get stronger, and that also means I have overcome the fear of the past and mastering this power." Izuku looked at his hand.

Izuku remembered how he was able to call out to the sword in order to beat that Reaper monster and save Mio from being taken. He really was grateful that the power answered his feelings when it did because it would have been really bad for everyone if he couldn't pull it off.

Not only that, but he also felt the desire to become a strong hero who can save lives with a brave smile for the people to look up to like he always felt back when he used to live with the Hero Clan.

(Flashback)

"And the hero saved the day, everyone was able to live happily ever after." A boy read the hero story to a younger Izuku.

"Wow! Wow! The hero saved the day again!" Little Izuku cheered.

"Big brother, I wanna become a hero like the ones in the story and our clan!" Little Izuku said to his big brother.

"Oh, are you saying you want to be stronger than everyone in the clan?" The big brother asked with a smile.

"Everyone is saying that you could be a greater hero than our dad, Basara. But I wanna become stronger than that and use that power to save people, no matter how scary things get! And I want to be heroes with you and dad together!" Little Izuku explained his dream.

"Well, we are a family of heroes." Basara smiled.

"Let's train really hard so we can heroes together." Basara petted his little brother's head, making him happy.

(Flashback End)

"(Big brother Basara, I'm going to keep the promise we made together. To become a hero.)" Izuku thought clutched his fist with a newfound determination.

"Hey, it's getting really late. So, I think it's about time we hit the hay." Ghislaine pointed out.

"Oh, you're right. I didn't realize it we were up longer than I thought." Izuku realized.

"Come on, I can show you the guest room." Izuku offered to let Ghislaine sleep in the guest room of the house.

"Thanks, though I wouldn't mind sleeping on the couch." Ghislaine said.

(The Next Day, Afternoon)

"Oh! I'm so glad that you girls are safe!" Sapphire hugged Mio and Maria in her arms with tears almost coming out of her eyes.

"You had no idea how worried I was when Izuku told us over the phone about the attack, I thought something bad may have happened and we weren't there to help you. But seeing you two in one piece just makes me so happy!" Sapphire sobbed a little, hugging onto the girls a little tighter.

"Oh, I'm glad you were worried about us." Maria exclaimed in pain.

"Honey, I think the girls have already felt your love enough, now please let them go before their faces turns blue." Raphaeline warned, getting her to let go of the two.

"Ghislaine, I'm really glad to see that you've been doing well since we last saw each other and being here means you have come to fulfill the promise you made with Jin." Raphaeline said to her old cat friend.

"That's right and let me say that your son is Hell strong to defeat a Reaper with one attack." Ghislaine nodded.

"Does that mean you used that sword?" Sapphire asked Izuku.

"I did." Izuku nodded with a smile.

"Oh, I'm so glad you were able to pull it off! I was really worried that you would have been in serious trouble if it ended up backfiring on you by sending you to another dimension where we won't be able to bring you back!" Raphaeline smiled proudly.

"(That's a lot of things that could go wrong.)" Izuku thought sweat dropped.

"So, it looks like you've taken the first step to overcoming yourself, huh?" Sapphire asked with a grin.

"Yes, this is only the start of my origin!" Izuku believed.

"Now, before we get dinner started. Mio, Maria, is there anything else we should know about like what happened in that fight and after?" Raphaeline asked the two girls.

"Well, there were actually two girls who suddenly showed up and saved me from some monsters. They sounded like this town is their territory, but they don't view us as their enemies. In fact, they seem to already know who we are." Maria informed about the two mystery women she encountered.

"Sounds like we should go hunt them down and see for myself." Sapphire said.

"Now, now, they saved our daughter, so we should let them be for now." Raphaeline advised, wanting to see if there is a way to meet them later.

"Not only that, but Izuku and Mio did the most incredible thing that will surely bring them closer than ever before!" Maria mentioned with a sly grin.

"(Oh on, she wouldn't dare tell them about that?)" Mio and Izuku thought feared of what Maria is about to do.

"They performed the Master-Servant pact!" Maria revealed with a cute smile.

"(WHY?!)" Izuku and Mio thought gasped in horror.

At first, Sapphire and Raphaeline were quite for a few seconds until their eyes widen like they're about to pop out of the sockets and their laws drop as they scream at the same time in shock.

"The Master-Servant pact?! As in the ritual where you have to bind your souls together by doing sexual things on one and making them scream in pleasure! That ritual?!" Raphaeline asked, freaking out about this.

"…Yes, we did it." Mio admitted.

"And I'm the master." Izuku said, raising his hand.

"Oh shit! I didn't think something like this would happen to our little green bunny this soon in his life and he's about to be in high school after summer too!" Sapphire screamed a little.

"I'm really sorry, but Maria told me that it would help me be alert in case Mio was ever in danger again and I would respond to that." Izuku explained.

"Yes, but she also left out an important detail on purpose just for her own amusement." Mio glared at Maria, making the Succubus girl whistle innocently.

"If it's already done, then I'm afraid there is nothing we can do about it. But I do get a feeling that we might end up hearing their ritual session in the near future." Raphaeline blushed a bit.

"Yeah, that'll probably make us remember the time Jin had his way with us back in the days." Sapphire chuckled, blushing as well from the memories.

"C-Can we just go have dinner now?" Izuku asked, wanting to leave the subject behind for a long while now.

KO a new chapter is done and hope you all enjoy it!

Well, the pact has officially been done with Izuku becoming the Master and Mio has become the Servant to build their bonds together, and now the moms know about the pact though something tells me that they might get themselves involve with the pact more than they'll realize.
