LUCIFER

• Proud of himself that he had chosen a competent exchange student
• You were quiet, straight forward, and was excellent in your studies at Devildom, it took only a few days for you to fully adapt into RAD
• You were curious of your surroundings when you first arrived in Devildom, leering more at the architecture and environment than interacting with him or Diavolo
• The first day of RAD, during your classes he was told that you were slightly behind the other students, but that’s to be expected of someone who never even heard of the subjects they taught, and that you would probably catch up within the next few days.
• That night, he saw you take several books from the library and return them the next day, and what was supposed to take a few days of learning took no more than a single day for you.
• You were ahead of practically everyone in class, rivalling Satan in academics, but beat him in Alchemy, much to everyone’s shock
• It was like you were born to be an alchemist- no, born from alchemy itself
• That was when Lucifer found out you were not only an alchemist, but CHIEF alchemist up in the human world AND the captain of the investigation team
• Well that answered the question surrounding your natural curiosity
• The way you studied and held numerous questions about Devildom, RAD, and various other topics, he had to take two days off just to answer your questions.
• Found out about your hobbies in art and drawing when one day you just handed him a sketch of himself, doing paperwork on his desk, and left without another word
• His pride had definitely swollen up to ten times its size, that was until he found out it was just a.. Thing of yours to sketch people and gift them the drawings
• His pride was taken down several notches when he found out Mephistopheles was one of your more favorite subjects to draw, and I quote, “I can take several hours sketching Mephistopheles, it’s quite hard to capture his emotions right.”
• He avoided you the entire day after gaining this knowledge, not that it disturbed you really.

MAMMON

• Mammon was weirded out by you at first, you’re always neutral expression, your calm, smooth, and slightly tired voice expressing your emotions and intentions quite badly
• Didn’t really think about you two getting along and becoming friends because, y’know. He was loud, noisy, and makes his presence known, while you were quiet, observing, and just analytical overall
• Little did he know that opposites indeed attract, especially in this situation
• You two didn’t really have a moment where something just told you, “Hey, try to talk to them.” You and Mammon just.. Hang around each other
• Mainly because he was assigned to be your babysitter and Lucifer had threatened to string him up from the ceiling again
• He could feel Lucifer’s pride swell up when you were adapting to Devildom so well
• Sometimes he would talk and make conversation with random topics, one time it ranged from the car in his room, how he got it inside his room, to ranting about how Lucifer never acknowledged the work he puts in but somehow still trusts him, and then to watching a movie on the projector screen he has.
• After a few times of this, Mammon asked if he was being annoying and if you’d like for him to shut up and leave you alone, to which you shook your head, still with a neutral expression on your voice, and said. “I found you very interesting, Mammon. You’re a great company to have, and despite how much bullying your brothers bestowed on you, you still dote on them and love them unconditionally to the point where it’s slightly concerning. But, that’s besides the point. What I’m saying is that you make a good..friend to have.”
• That was the most Mammon had ever heard you talk, and he had to stop himself from dropping his jaw.
• After that, he came to know that you liked to learn, especially about the world around you.
• The first of all the brothers to find out that you’re a Chief Alchemist and Captain of an investigation team.
• He could ask you one thing and you probably know about it to an extensive degree, and he thinks listening to your voice just ramble on is really nice and relaxing, the amount of times he had accidentally dozed off to the sound of your voice is impeccable
• Loves it when you talk about something to him, it reminds him that you’re comfortable with him enough to talk about mundane things in life or some other things you had come up with.
• First to also find out you were a synthetic human, being created out of ‘chalk’ with no blood relatives. You had some other ‘siblings’ made of the same things, but all were either failed experiments or were simply not up to expectations, and were eaten by Durin, a venomous dragon.
• Your origin was definitely an answer to his question to the diamond on your neck.
• Once you two established enough comfort and trust with one another, he liked to trace the outline of the diamond with his fingertips
• Nearly hit him with a sketchbook once he compared the diamond to a belly button
• Also made it a goal in his life to check if you do have a belly button
• It’s an inside joke between the both of you now
• Also one of your favorite people to draw, you nearly filled a sketchbook with just him
• He makes a good subject, and having already been a model, he’s very attractive and pretty

LEVIATHAN

• Didn’t really care nor pay attention to you
• That until the whole TSL thing happened, and the series had piqued your interest
• Because of this, he told you that it was originally a book series that had been adapted into film and the books are so much better and very well written and that, my folks, is how Levi got you hooked onto TSL
• So much so that you had came to his room and asked of how he envisions these characters to look like
• Levi, not knowing of anything, happily ranted and heavily projected onto the Lord of Shadow
• And before he knew it, he was staring at the seven lords and they were all staring back at him.
• “WOAAAAAAAAAAAAAAAAAAH!!!”
• He had stars in his eyes as he held your work in his hands.
• “MC you could TOTALLY become an animator or mangaka with these skills!”
• “Actually, I have already illustrated a book for a friend.”
  “WOAAAAAAAAAAAAAAH!!!!”
• Definitely added a mental note to himself to read the book you had illustrated, not because he wanted to stare at your drawings, of course not.
• First of the brothers to find out about your hobby in the arts.
• Also has a fairly big dedication section in your sketchbook, because despite him not leaving his room that much, he had one of the more harder to sketch poses, with his baggy clothes, posture, and ways of sitting, it was a challenge that you happily accept
• Blushed so hard when he found out that you drew him.
• Adopted you as his Henry and has tried multiple times to steal you away from Mammon, and while he and Mammon argued you just walked off because you found a certain flower you had never seen before.

SATAN

• Only acknowledged you after you had rivalled him in academics
• Took this as a challenge and easily declared you his rival
• And then you beat him in Alchemy and not only was he confused, he was also kind of angry because you just showed up out of the blue, no knowledge of Devildom whatsoever, and then have the audacity to try and beat him?
• Put a bitter taste in his mouth
• Often sees you in the library with too many books around you and did not know whether you were studying a subject or learning something out of your own pure interest
• Established a competition with you that only existed in his own mind
• In your mind in the other hand, you admired him for his extensive knowledge and sharp tongue
• Would literally stare daggers into your back and you wouldn’t pay him even an ounce of attention
• So you two have very different views on one another
• Asmo asked him about this once and he only nodded, and said you were a great student that he values as his rival.
• Then Asmo asked what you thought of Satan and you said you liked his sharp tongue and wit, not even mentioning him as some sort of rival.
• Asmo found this funny and kept quiet.
• Satan was also one of your favorite subjects to draw, the emotions he keeps inside of him and never let show was.. Complicated to portray
• The first time you managed to sketch his character perfectly, you handed him the drawing and left without another word
• Satan took this as you challenging him or maybe you telling him you see him as an equal?? He was very confused by this
• The only brother to know about your power in geo
• Well, except Mammon because you and Mammon knew everything about each other which was fairly weird but no one ever brings it up
• He found out during one of your numerous experiments that he likes to watch from time to time, he’d give his input and thoughts from time to time but other than that, he was usually just a viewer
• Nearly choked on his drink when you just did MAGIC like it was nothing
• When did you learn magic?? Did you have Solomon teach you when they weren’t looking?? How did you do that?? I’m-
• That was when he learned about the existence of Visions, Archons, and whatnot
• Burst out laughing when he learned that their demon Barbatos shares a name with the Anemo Archon
• He held numerous questions about your Vision, your skills, and so much more. You two became friends as you grew closer day by day.
• Still considers you to be his academic rival though.
• But he happily yields his top spot in Alchemy for you.

ASMODEUS

• Made it his life goal to have to sketch him just as much as Mammon
• Said goal was crushed when you said, “I can simply draw you in three strokes, Asmodeus. One for your face, one for your hair.. Two strokes, actually.”
• Whined and groaned about this to Satan, but he still doesn’t give up.
• Always poses and tries to get his good side to a 100% whenever he sees you carrying some paper and pencils
• Was thrilled and casually held his pose for a full hour when he finds out you were just sketching the flower vase behind him
• After a month of this, Satan obviously grew tired of Asmo’s whining and dragged him towards you and made Asmo tell you everything of what he tried to do the past month
• And you responded, “If you wanted me to draw you so badly, you could have just asked.” And brought out that damned sketchbook that haunted Asmo in his dreams.
• Treasures the sketch of himself and puts it in a picture frame on his bedside table.
• Still very salty and petty about the comment you made about sketching him in two strokes, but he does make several innuendos along the way that you pointedly ignore with all your might
• Can and will shamefully admit that you are very attractive and pretty
• The amount of times this man tries to drag you to Majolish and have to model
• He did it successfully one time and you were promptly banned from ever becoming a model due to all the fan letters, stalkers, and nosebleeds you had caused all around Devildom
• It was a national incident and also the day that an MC Fanclub was established.
• Asmo definitely takes pictures of you doing anything and posts it to Devilgram and it reaches over one hundred thousand likes
• He was in the garden area of the House of Lamentation to take some pictures because the flowers were in full bloom and there he spotted you, crouching down to look at a very vibrant and yellow Devildom-native flower, with some other flowers that shared equal vibrancy in your arms, placed right on top of a flower encyclopedia he didn’t know existed
• Took a sneaky pic of you and posted it to Devilgram of course
• He merely wanted to share your beauty with the others! Especially after you were banned from modelling at Majolish.
• Is very salty about a simple picture of you gaining more attention than a few of his other posts but he knows that he’s still the prettiest in the land, he wasn’t the Avatar of Lust for anything, y’know
• You think of him like how canon Albedo thinks of Kaeya. 

BEELZEBUB

• Loves your cooking so much I swear this guy
• Whenever it was your turn to cook, Beel makes himself in the kitchen and becomes your taste tester
• You liked to experiment with your food too, but now especially in Devildom, your palette and cooking skills increased exponentially and, from Beel’s words, can even rival Ristorante Six
• The way you smiled so genuinely and shyly due to his compliments also made him smile
• Had a few questions about the diamond on your neck but doesn’t bother asking it
• Whenever he was falling behind on a subject, he’d always come to you for help, knowing that the way you explained things kept him hooked and paying attention, that and he loved hearing your normally hidden away voice
• Encourages you to talk more about your interests, what you think of Devildom, and whatever else, even if he doesn’t understand what you’re saying, he would still be an attentive listener.
• You requested to join him whenever he goes to the gym or Fangol Practice
• It was during one of the trips to the gym where you joined when he found out about your skill with a sword
• You were elegant, skilled, and almost looked like you were dancing with the blade. Nothing like a warrior, but instead a graceful knight.
• King of Compliments and has the record of having made you blush the most with Mammon holding the made you smile the most record.

BELPHEGOR

• Found your voice very soothing to listen to if it wasn’t monotonous
• Didn’t like how much you asked questions on his person, why he was up in the attic, and whatever else. It made it hard for him to get you to unlock the door while keeping the lie up.
• Found himself sleeping on too many occasions when he was supposed to be manipulating you and stuff
• And he felt himself being watched while he was asleep and it kind of freaked him out
• You found him easier to sketch because he was always still and didn’t really have that much expressions on his face
• In the time of lesson 16, it was the first time he ever really noticed the diamond on your neck
• How couldn’t he when he was literally choking you to death?

• Lovingly traced the diamond with his fingertips while asking various questions about it, mirroring how you used to ask him questions in your first meeting

• The only difference this time was that you didn’t answer him, you couldn’t. You were busy trying to rip his hands off and take a breath
• Then, you had mustered enough energy to summon a powerful enough geo to push him back, and you began to run away, but he had gotten up and caught you
• You couldn’t summon out your sword, you had left it in your room, not knowing that you were going to fight for your life just a few hours later
• So you relied on your Vision, and soon enough, you two were nearing the Entrance Hall, and you backed up against the railing, and fell.
• Mammon caught you after he tried to see what the commotion was about, and he was shocked to see his little brother attempting to murder the human he cared about so much, and then the other brothers trickled in after Belphie started yelling.
• Things were soon resolved after that, with you passing out from a combination of lack of oxygen, exhaustion, and sleep deprivation
• After that..incident, Belphie didn’t expect you to like him at all, he had half expected you to avoid him or even hate his guts
• Imagine his surprise when you continued your life and relationship with him like he had not just attempted to kill you
• You hang around him, you talked to him, but he couldn’t keep his eyes away from your neck
• The diamond on your neck was alluring, and full of mystery. He knew humans had birthmarks and things related to that, but the one on your neck was just too perfect and symmetrical to be considered one.
• Sometimes finds himself tracing the diamond on your neck too
• Whenever one of the brothers sees him doing this, they couldn’t help but flinch at his hand nearing your neck, especially Mammon.
• He didn't ask about the mark, feeling like it was too personal of a question for your relationship with him, so this was the closest thing he could do regarding the mark.

SCENARIO

• One day, Lucifer came home to see his office wrecked; chairs upturned, lights smashed in, couches and pillows ripped, and his paperwork all strewn and everywhere
• First person to come to mind was Mammon, but he knew his brother won’t even dare to do something like this
• Actually, none of his brothers would do this. Not even Satan or Belphie, the most they’d do is steal his pillows and chairs, not trash everything
• With anger bubbling inside of him, he fixed his study. And while he was arranging his paperwork, he found several important notes missing. Notes regarding the Exchange Student Program, upcoming school and personal events, and MC.
• “Heeeeey! Lucifer dinner’s about to be serve- what the hell happened here?? Did you get in a fight with a pigeon?!”
• Mammon balked at the state of Lucifer’s office, his emotions too genuine to be faked. He wasn’t the one who did this.
• Lucifer sighs, “I did not fight with a pigeon-” “A peacock then?” “MAMMON!” He took a deep breath to calm himself, “No, I did not fight with a pigeon, a peacock, or whatever bird you’re thinking of. I came home to see my study in a much ruined state than this.”
• Mammon furrowed his brows, crossing his arms, “No one was even near yer study while you were gone. Someone coulda broke in??”
• “Just to trash my office and steal documents?”
• “I don’ know, is there anyone who may hold a grudge on you?”
• “None that I remember-.. Mephistopheles is busy with his demonus collection to do this, and if he did all of you could practically hear him from a mile away.”
• “Mammon, Lucifer, dinner’s ready.” Beel appeared in the doorway, eyes widening at the state of the office and about to ask but Lucifer said he was going to explain at dinner.
• They all went downstairs.
• During dinner, Beel kept sending nervous and questioning glances towards Mammon, who gave him a look that said ‘Wait.’
• After Lucifer finished eating, he cleared his throat to gain the attention of his brothers and the lone human.
• “When I left for my meeting with Diavolo, did any of you see someone enter or leave my office?”
• Beel froze as he realizes what had happened, but shook his head, because he was out the whole day for Fangol practice.
• Belphie sighed a no, obviously tired and wanting to go back to sleep. Everyone else shook their heads with a resounding no, making Lucifer groan as he realizes that he may have to take this problem further.
• When Asmo spoke up, “I think I saw MC walk towards your office just this earlier, I told them that you were out and left before I saw what they did next.”
• The tension was thick as everyone looked at you, looking at them with confusion as you put your fork down
• Mammon soon found out what they were implying, and tried putting a stop to it. “MC was with me the entire day! They couldn’t have trashed Lucifer’s office.”
• “Now that I think about it, I did see MC leave your office a couple of hours ago,” Belphie yawned. And Mammon gritted his teeth.
• “MC?” Lucifer frowned, “Yes?” “Is this true? Were you the one who tr-.. Who was in my study?”
• You hummed and shook your head, “No, I was with Mammon the entire day, I have no memory of ever going to your office, let alone the hallway towards it.”
• “No! I totally saw you enter Lucifer’s office,” Asmo gave a sly smirk, “I think you were planning to surprise him, weren’t you, MC? No need to lie~! I know my sin when I see it!”
• Everyone groaned at Asmo’s accusations, and Lucifer merely coughed his away, you looked slightly perturbed by this but didn’t let it show
• “I’m not sure where you got that idea from, but I assure you that I feel no lust towards Lucifer. I have no memory of ever going into his study in the first place, I already said that I was with Mammon the entire day, what else are you asking of me?” You said sharply, sighing at the situation.
• “If Mammon’s your only alibi it’s a lost on your part, MC,” Belphie sighs, resting his head on the table, “We all know that Mammon’s as scummy as it gets, and I have no doubt that he’ll lie for your sake.”
• “Stop calling Mammon scum.”
• Lucifer puts a stop between you and Belphie, “Is there anyone else who can back Asmo’s or MC’s claims?” and Satan recalls, “When I was going to the library I saw MC shuffling around with some papers in their hand, Mammon was nowhere in sight.”
• “I was in the library for a short period of time, but I had no papers in hand.”
• Beel speaks, “While I was out grabbing lunch I saw MC walking around in Devildom, Mammon was nowhere.”
• It was clear that their evidence pile was bigger than you and Mammon’s alibis, with four of the seven brothers agreeing to see you not in the House of Lamentation nor with Mammon, Lucifer was angered.
• Satan snaps his head towards Lucifer, shocked to see the immediate snap of emotions the eldest had. And for once, he was scared for you. And Beel felt something in his gust twist and turn as he asks, “What happened in your study, Lucifer?”
• “I came home to see it trashed and several papers missing.” Lucifer gritted his teeth, “And it seems like our dear MC is the cause of it.”
• Asmo’s face paled as he realizes the mistake he had done, and your face was still neutral, besides the furrowing of your brows.
• “Your punishment will be given tomorrow, only the Demon King knows what I’d do to you in the heat of my anger. Go to your room.”
• And you did, with no other word, with no exclamation of being framed, nothing. You only stood up, gave Beel the rest of your dinner, and left.
• The next day, Mammon didn’t see you in your room, and didn’t see you eat breakfast either. So, before going to RAD, he and the other brothers searched for your whereabouts, fearing that Lucifer might have smited you out of existence.
• That until he saw you hanging upside down above the staircase, where he was usually hanged during his punishments. “MC! Are you ok?!”
• You were slowly spinning and only answered when you two were facing each other, “I’m fine, I ate breakfast before this happened, no need to worry about me starving.”
• “That’s not why I’m worried! Wait, I’ll help you down.”
• “Stop what you’re doing, Mammon.” Lucifer descended from the stairs, pinching the bridge of his nose, and you nodded. “I agreed to this punishment, so if it would be nice, I’d like to finish it by my own terms too.”
• “But you’re innocent! You were with me the entire day-” “Asmo, Belphie, Satan, and Beel’s statements contradict your own. Now let’s get going, we’re going to be late.”
• Mammon glared at Lucifer as he pushes him away from you, giving you a look of pity, to which you didn’t see.
• The entire day, Mammon was bored out of his mind, he missed bothering you, how did he survive RAD before the program?! He groaned as he goes back home, carrying ice cream to gift you.
• Back at the house, you were rubbing your sore wrists and ankles, unbelievably tired and bored from being strung up, enjoying the ice cream Mammon bought you as he recounts what had happened at RAD.
• It was when you two heard commotion originating from downstairs that you stood up.and checked what was going on.
• You didn’t expect to see Simeon, angry as hell, yelling at Lucifer.
• “-They hurt Luke! He was only offering them a treat when they insulted his baking and pushed him into a locker.” “MC was in the House of Lamentation since morning, they couldn’t have attended RAD strung up from the ceiling.” “Strung up? What did they do- you.”
• Simeon’s head snapped towards you, anger radiating in the air as he nearly flew to get on top of the staircase if you and Mammon hadn’t walked down.
• Mammon spoke for you, “I don’t know what happened, but MC was definitely not at RAD, and they can’t really escape from being hanged midair and tie themself back up.”
• Simeon narrows his eyes, grabbing your wrists and see the angry red rope burns before sighing, “After seeing you hurt Luke just this earlier and then these burns, I’m not sure what to believe.” He heals them for you. “But.. stay away from Luke in the meantime, he’s still hurt from what you did.”
• You nodded, and Simeon leaves with no other word. The brothers have all gathered in the entrance to see the commotion, all disturbed to see you in trouble again.
• You went back to your room with Mammon in tow.
• Days had passed from these two incidents, Luke was acting weird around you, but was still nice.
• Then came the announcement for the brothers, the angels, and the two human exchange students to have a small hangout, a get together, at the palace.
• Everyone was obviously excited, but you were skeptical, almost worried, and only Mammon brought it up with you, and was only given an answer that wasn’t related to his question.
• “If I act weird, do something off, or hurt anyone. I give you full permission to hurt and/or knock me out, don’t hold back.”
• Mammon’s eyes widen at this sudden request, “H-hold on, you- are you sure?? I’m the second born, you do realize that- why are you telling me this?!”
• “Because you’re the only one I can trust in this situation, please. It’s for the best, I won’t be mad at you if you do, alright?”
• Mammon reluctantly agrees.
• Things were going well when everyone arrived at the Palace, and you were acting normally all throughout the night, that was until you returned from the bathroom.
• Your movements were off, something was strange about you, your speech wasn’t just… you
• But Mammon kept still and quiet, unsure of what to do. Thinking that just maybe he was just imagining things.
• Then, you two locked eyes. And Mammon’s travels down to your neck, and a whole digs itself in his stomach.

• ‘This diamond on my neck is a birthmark, one that I am proud of. It tells the story of how I was made, how I was created as a synthetic human being. And this imperfection is a sign that I am imperfect, just like everyone else.’ Your words echo into his mind, and he makes a move.

• Transforming into his demon form had caused a ruckus, and everyone was yelling at him to stop. But how could he when you had given him an order through your pact?
• In the eyes of the observer, you two were having a silent conversation, until Mammon transformed and attacked you with a punch, and you pushed yourself away with him with magic.
• Everyone was yelling, trying to stop Mammon from attacking you, and the others trying to stop you from attacking Mammon.
• Luke, who was away from the fight, was humming in the halls, having just went to the bathroom, when he felt something through the door of a supply closet
• He looked down the hallways, unsure of what to do. There was nobody around to help him in the situation, he can’t disturb Simeon and ask for his help, Barbatos was nowhere to be found, and the Little Ds never show themselves.
• He makes a decision, and opens the door.
• Shock rattles in his bones as he sees you, hang up from the ceiling, entire body tied, head near the floor, and a piece of tape on your mouth. You looked relieved to see the little angel.
• “MC! What are you doing here?! Weren’t you in the ballroom??” He says as he unties you, ripping off the tape on your mouth, allowing you to take a deep breath.
• “That’s not me.”
• Back in the ballroom, ‘you’ and Mammon were still fighting, and Lucifer’s patience had already ran out as he tries to chase Mammon down and supplex him. But that proved to be impossible because Mammon was indeed the fastest among all the brothers.
• ‘You’ on the other hand were of no help. As you repeatedly escaped from Beel's capture and attacking everyone on sight, Simeon and Solomon being protected by Barbatos while Diavolo tries to settle things down.
• Things went to an even DEEPER level of shit when you and Luke entered
• Simeon called out Luke’s name, telling him that it wasn’t safe in the ballroom, but his words died in his mouth when his eyes landed on you, right behind Luke, when there was also another you who was busy simultaneously attacking Lucifer and Mammon.
• The real you summoned your sword, and joined in the fray, attacking yourself.
• “Mammon, stop!” You ordered, and he did stop. Panting as he falls in Lucifer’s arms, tired from having to fight someone who held nearly the same looks as someone dear to him.
• Things de-escalated from there, the impostor you had disappeared after you nearly beat it, no one went to try and chase it down, and Mammon stumbled forward towards you.
• “Are ya ok?! Where were you when the impostor showed up? They didn’t hurt you right?!”
• Luke piped up, “I found MC in the supply closet, they were tied up and had tape over their mouth, they looked fine though.” Mammon thanked Luke, and turned back to you.
• “When did they switch with you?” “Right after I went into the bathroom. How did you realize that it wasn’t me?” “The impostor didn’t have the diamond on their neck.”
• It took several hours for everyone else to calm down, and for you to explain your origins, and of the existence of an ‘evil twin’ that was a failed experiment to create a You.
• It was a wild sequence of events.
• And an even wilder time for everyone once they had realized that synthetic humans existed, humans who were born out of Alchemy, and while this answered Satan’s question on how you were so skilled, it unnerved everyone on how enigmatic your entire being was, and how Mammon was the only brother truly close to you to even know about it.
