The one Where Izuku became a Stalker

Summary:

Midoriya Izuku never expected his life to change so drastically when his mother decided to house his second cousin twice removed. But who knows? Living with a genius boy makes life more interesting, he just didn't know he would become a professional stalker after all this, and of course, Katsuki was there for the ride too.

The second of a serie where the characters of Bungou Stray Dogs reincarnate in the world of Boku no Hero because I love crossovers and Bungou Stray Dogs need more of it.

Notes:

The one Where Izuku became a Stalker

 

Edogawa Ranpo was a strange boy, and Izuku didn’t mean it in a bad way! He swears! Izuku was also kind of strange in a good way, Ranpo-kun was just… Stranger. 

The boy that now was living with his family was in many ways similar to him, he also had green eyes (Though his eyes were much brighter than his), had the same age as him (Eight) and was also Quirkless. What was expected, since they were family in some way, he tried to look into the internet but he still couldn't understand very well how they were related. Something about his grandfather being Izuku’s grandfather's cousin?

But the similarities ended there, Ranpo-kun was much more energetic than he ever could be. The boy was quirkless like him, however, somehow he managed to become Kacchan's rival in his first week there.

Izuku remembers that day very well, his mom had asked him to show Ranpo-kun the neighborhood and Izuku, that had passed the last week hiding in his home afraid of what Bakugou would do when he found out that he had a fragile quirkless cousin, was forced to go out.

The trip to the park was very normal and Izuku was even hopeful that Kacchan wasn’t going to be there today. He even managed to talk with Ranpo-kun!

“You’re excited to start studying in that private school?” He had asked, the reason for Ranpo-kun to be living with his family now was that he was accepted in a prestigious school in Musutafu and the little village where he lived was too far away from the school.

Izuku firmly believed that Ranpo was a genius, he didn’t know much about private schools, but Yuga Private School was the most prestigious and expensive school in Musutafu, if Ranpo was able to study there just with his grades he had to be at least smart.

Of course, he didn’t act at all like a genius type of person, but Izuku knew better, Ranpo had to be some kind of super genius behind all the ‘I don’t Know how to walk in the street’ persona. 

“Not much, actually” Ranpo had answered “But I'm excited to eat the dessert that they serve in the school! I heard it is a big cake with ice…”

“OY DEKU! Who's that?!” Izuku shivered a little when he heard Kacchan’s voice, of course he would be in the park! He was always there! 

“-Cream, with chocolate and red fruits, I can’t believe they actually serve a dessert in school, but it was expected from one so prideful like YPS…” And Ranpo just ignored the boy… What made Izuku look at him as if he was crazy, who keeps talking about desserts when an angry boy that makes explosions is yelling at you?!

Of course, that made Kacchan angrier and he walked to them with explosions already forming in his hands

“Don’t think you can ignore me, nerd!” He yelled, his hands going direct to Izuku as usual, at last if Ranpo ran he would be able to escape from Kacchans rage. After all, the blond boy just looked to have something against him and the people that tried to talk with him.

Ranpo would be fine if he runned and stopped talking with him in public…

His tangent of thoughts was interrupted by Kacchan frustrated sound, Izuku opened his eyes to see Kacchan hands and shirt wet, Ranpo had thrown the water in his bottle at Kacchan, stopping the explosions immediately

“WHAT THE-”

“My name is Edogawa Ranpo, I’m the greatest detective in the world!” Ranpo said putting the bottle back in his shoulder bag and staring at Kacchan as if he was just a minor inconvenience “Izukun here was going to take me to the candy shop! So excuse us!” And then he dragged Izuku by his shoulder and passed straight for Kacchan.

“I’M GOING TO KILL YOU!”

 

And like that, Kacchan, Izuku and Ranpo ended up going together to a candy shop, Kacchan yelling at Ranpo whenever possible, and of course, Ranpo didn’t even take it seriously, just ignoring him and buying more candies.

“As soon as my hands are dry I’m going to explode your head off!”

“I can just wet them again”

“I- You can’t!” Kacchan did look to finally realize that Ranpo could and would throw more water at him.

“Even if I couldn’t, there are many other ways to stop your quirk,” Ranpo explained, looking thoughtful at the lollipops flavors.   

Kacchan stopped yelling and his angry face also disappeared, now looking at Ranpo with a raised eyebrow and some confusion, this was the first time in some years that Izuku had seen Kacchan with another expression besides anger.

“How?” Kacchan actually looked interested and for some seconds Izuku actually thought that they could become friends… For a few seconds.

“Ah? Why would I tell you?” Ranpo said with an annoying voice “Maybe if you buy some candies for me…”

“I’M GOING TO KILL YOU, YOUR QUIRKLESS PIECE OF-” And the explosions were back, and again, Ranpo just tossed the water at him, this time wetting all the boy.

 

They were kicked out of the store after that.

 

Izuku could admit that this memorie was a happy one, for the first time Kacchan actually talked with him. After the incident at the store, Ranpo somehow made Kacchan buy him candies in another store and all three of them sat in the park to eat.

They talked, Kacchan yelled, Ranpo ate his candies and after that, Ranpo and Izuku would meet Kacchan at the park every saturday.

Thanks to Ranpo some kind of friendship that he had lost was back, of course, these encounters were more of Kacchan trying to attack Ranpo than actually hanging out, but it still was fun.

 

Obviously, Izuku’s life changed a lot when Edogawa Ranpo came to his house. 

So, it wasn’t that surprising that Izuku started to study his cousin.

And again, not in a bad way, alright! Izuku was just a curious kid and he loved his quirk analysis notebooks, quirks were fascinating and Izuku couldn’t help, he had to write, analyze and study them!

With Ranpo was the same thing. 

He didn’t had a quirk, was the first thing his mother said to him when the boy moved in (What was kind of rude to the boy, but Izuku know that his mother just wanted him to relate with someone of his age), but even being quirkless he was one of the persons Izuku would write a special notebook dedicated to them.

And maybe that notebook had started just as an analysis, where he would write the proof that Ranpo was a genius and try to explain his personality (Without success), but the things kind of… Escalated quickly. 

First, Kacchan found out about the notebook.

“Why the hell do you have a notebook about your cousin?” The blonde boy had asked, picking the object from Izuku’s desk. Both the boys were at school, two months had already passed since Ranpo came to Musutafu and the things between Izuku and Katsuki had change a lot, Kacchan still avoided talking to him, however, if it was to complain or plan the fall of certain Edogawa Ranpo, Katsuki didn’t saw any problem in talking with Izuku.

“Ern… You see… I like to study him?” Izuku moved his hands uncomfortably, avoiding looking at Bakugou eyes.

“He's not some kind of wild animal” Bakugou rolled his eyes and opened the notebook. Leafing through it bluntly.

“I know! But he is an… Interesting person!” Izuku defended himself “There is much to write about him!”

“You have a page about his favorite candies” He mocked and Izuku blushed. Bakugou ignored him and kept reading, humming a little interested. “Here, it says that the bastard is more relaxed when he's eating caramel…”

“Yes! That’s very curious actually, I believe that the crystallized sugar is a much more—”

“SHUT UP!” And Izuku immediately went silent “What I want to know is if eating caramel wold make him more easy to attack”

Izuku, still afraid of speaking, just nodded. 

Bakugou's smile grew as if he was already imagining Ranpo’s defeat.

They tried and as Izuku thought, didn’t work at all.

When he ate caramel, Ranpo was more relaxed and almost sleepy, which would make a surprise attack easy.

However, to work, a surprise attack need to be, well, a surprise 

If Izuku was right, Ranpo probably already knew about Bakugou's intentions the moment he stepped on the playground. It wasn’t like Kacchan was trying to hide it, he was just being too cocky that day.

In the moment that Bakugou tried to sneak into Ranpo, that was chilling in the ground, he just raised his leg a little in the right moment, making Bakugou stumble right into the playground’s sandbox.

Well, it was inevitable, Bakugou would have to train much more years before he was able to successfully attack Ranpo.

So, after that incident, Kacchan decided that he and Izuku would study Ranpo together, and it was kind of simple, they just spent the lunch time writing down everything they knew about Ranpo.

Normal, right? 

Things just got a little more complex a year later, when they threw out the window all the ideas of studying Ranpo and decided to… How do you say “Stalk” without sounding too bad? 

Maybe they had Ranpo’s routine written down, or his sleep pattern, or maybe an entire article about sweets and the possible sweet language that Ranpo (Accidentally? Purposely? Came to him in a dream?) created. But that wasn’t weird at all! Was just a hobby that he and Bakugou had.

And Ranpo probably knew about that already, he always looked to know about everything anyway.

Izuku just acknowledges that the things were going out of control when he and Bakugou used their day off (Their school had been going through a reform at the moment) to search through Ranpo things.





The Book

 

“Are you sure we should be doing this, Kaachan?” Izuku asked while he and Bakugou looked around Ranpo’s room

“Do you have any other ideas? Your Ranpo Analysis book is almost finished and I still didn’t win!” Bakugou complained opening Ranpo’s wardrobe 

“Yes, but this is kind of… Wrong?” Izuku said, but still, he walked around opening the nightstands. Izuku’s curiosity was his worst trait.

“Is your house too, dumbass” Bakugou said, still going through the clothes “Look! This guy doesn't have one hero cloth! He has an awful taste!”

“Ranpo doesn’t like heroes that much,” Izuku said looking at the empty notebooks that Ranpo had. “Why does he have empty notebooks?”

“He’s weird” Bakugou said moving to look below Ranpo’s bed

“Well, yes, but he’s also very smart, I doubt we are going to find something” Izuku signed, already given up on the boring quest. “Let’s go, it is wrong to look at other people's things anyway…”

“Haha! I found something!” Izuku immediately turned around

“What? What did you find?” The boy jumped to look over bakugou’s shoulder

“A book” He said showing what looked to be a pretty book “The Mystery in the Ball’s Room, is the title”

“A Mystery Book? Ranpo doesn't like these, he says it’s boring” Izuku said with a hand on his chin, all the times he talked about books with Ranpo passing on his mind.

“Well, so it has to be good” Bakugou said opening the book

“Wait! We can’t, if it’s below his bed it must be important to him!”

But Bakugou didn’t hear him, the moment he opened the book a bright light blinded them, and in seconds, both the boys disappeared from the room.

 

“A scream was heard from all the mansion, quick steps resound while all the guests runned at the Ballroom, only one drop of blood was on the floor, at the side of the dead poor girl.” 

 

Izuku and Bakugou fell on the ground, in front of them at least ten people looked horrorized to a dead body.

Izuku screamed and Bakugou looked angry at him. The people also looked back at them

“Detectives! Please, help us!” A woman cried “She was my daughter! Por Isabelle!”

“H-hum… Sorry but… W-What exactly… Dead People?” Izuku was shivering, he knew that it wasn’t a good idea to mess with Ranpo things!

“Get out of this, nerd. You are supposed to be the smart one” Bakugou rolled his eyes

“How can you be so calm! Someone is dead and we are at a British party!” Izuku screamed at Bakugou, something that he had never done before.

“Shut Up, Nerd!” Bakugou screamed at him, angry all over his face “We are in the book you stupid quirkless!”

Izuku stopped at that, he looked at Bakugou and realized that in no moment he used his quirk, and even being angry, the boy also looked worried.

“We are in the book” He grumbled with wide eyes

“Yes, I told you that. I Can’t use my quirk and we are in a Ballroom-”

"That 's so Cool!” Izuku's eyes were shining looking around “This quirk is so unique! How many uses it must have…”

“Nerd, we are stuck in a book, some focus would be good, you know?” Bakugou said, rolling his eyes.

“Ah, yes, you’re right” Izuku blushed and looked back at the guests “Sorry, what was happening again?”

Izuku and Bakugou were now sitting in the living room, eating some fake cheese and thinking about their situation

“We can just wait for Ranpo, he probably knows what to do,” Izuku said, hiding his head on the pretty couch.

“Wait for rescue? That the best you can do?” Bakugou mocked “We probably just need to solve the Mystery”

“How can you be sure?” Izuku asked looking at the boy 

“Well, is a quirk, It need to have a weak point, and since is a projector quirk that don’t need of the user, the weak point probably is in the object” Bakugou explained

“Own, you’ve read my notes about quirks” Izuku said, a small smile on his face.

“Shut up” Bakugou blushed, he didn’t want to admit it but Izuku was very smart when the topic was quirks.

Izuku’s smile grew and he jumped out of the couch

"Let 's go then! This can’t be too hard”



“This is impossible” Izuku said, all the energy leaving his body.

Now the boys were at the crime scene, the body was still there, and both Izuku and Bakugou were sitting a little far away from it.

“Don’t give up yet, I thought you were all about helping others, deku” Bakugou complained to him, Izuku was always saying that he wanted to be a hero but now he gave up? He always knew that the nerd was a useless kid. 

“We already talked with the suspects and looked at the crime scene, that is a Rank-A Mystery Book” Izuku said to him, a little of emotion back on his expression “The secret to solve a Mystery is discover the motive and the means, and in Mystery Books the suspects always have one or two of them, in this book? They don’t have any”

“Well, they must have, you just isn’t seeing it” Bakugou said sitting at his side

“We talked to them in the same room, if one of them was lying the others would have snitch on him” Izuku said the obviously 

“So we are doomed!” Bakugou said, throwing his hands in the air, all his patience running out “Trapped for all eternity in an English book!”

They stayed in silence after that. At last it was what Bakugou was planing, one minute after that Izuku jumped out of the floor

“An English Book!” He yelled

“You already lost your sanity? What are you doing?!” Bakugou screamed at him

"It 's in English! We know basic English because of your grandmother!” Izuku turned to look at him like a maniac 

“Yes, if she hadn’t teach us something we would be lost” Bakugou said confused

"At! It’s said that the guests runned <stronger>at</stronger> the Ballroom!” Izuku was now jumping around in happiness

“And?”

“We don’t know everything about English so we didn’t notice at first, what made this the perfect Mystery for us!”

“DEKU! Just tell me what you mean!” Bakugou got up to scream at Izuku’s face

“It was the guests! They all killed her!” Izuku said happy and the bright light was back.

 

In seconds they were back to Ranpo’s room, but this time Ranpo was in his bed looking at his laptop.

“Finally, you guys were taking your time there” Ranpo said without taking his eyes of the screen

“Ranpo! That was amazing! What quir-”

Izuku was pushed to the side by Bakugo, who was with a red face and explosions already going out of his hands

“What the hell! Are you insane?! You knew that we were there and did nothing?!” Bakugou yelled, going straight to Ranpo’s face with his dangerous hands ready to cause some burns.

Ranpo, probably already expecting this, just held his pillow in front of Bakugou, sacrificing his pillow and saving his face.

“I knew you guys would get out, that book was a joke” Ranpo said, using the pillow and his legs to push Bakugou out of the bed.

Before Bakugou could jump back at Ranpo, Izuku held him back by the shirt, his curiosity was almost hitting the roof, he needed to ask his questions and Bakugou wasn’t going to stop him.

“Joke?”

“Yes, I asked my friend to make a easy one to you guys, this was the simplest way to make you busy while I was in School” Ranpo said shrugging

“Easy?!” Bakugou was ready to go back to the attack

“Yes, that book was so easy, I wouldn’t be there for more than one second” Ranpo said as if it was a fact, a simple fact that they already should know. 

“AHRG! You’re unbearable!” Bakugou said and left the room, closing the door hard enough to make Izuku jump

“He is always fun to mess up with” Ranpo chuckled

“So… You said a friend made that?” Izuku sat on the bed, excited to ask his questions about the mysterious quirk.

“Yes, he’s very nice, always send me these books, but they don’t make all this every time, just when he activate his quirk” Ranpo told him

Izuku widened his eyes and opened his mouth in shock.

“Wait! Did you tell him the exact same time we would be messing with the book?!”

Ranpo just smiled at him as if it answered his questions.

 

That day, a new entrance was added to the Ranpo Analizes Book.

 

The Rival

 

“Kaachan, that’s not a good idea” Izuku was already tired of having to say that phrase

“Come on Deku, It’s just a laptop” Bakugou said picking turning the laptop on

“It’s the only thing Ranpo brought with him from home, surely is something we shouldn’t look” Izuku said sitting at Bakugou’s side

It was going to be almost one year since the last time the boys tried to search through  Ranpo things, there weren't many opportunities since then, and the next thing the boys wanted to do was look at Ranpo’s laptop, but he was always with it (What was even more suspect).

Today, however, was Ranpo’s birthday and his grandfather came to visit him, so Ranpo was out of the house probably doing fun things, and while Inko was busy setting up a surprise party, the boys thought it was the perfect time to proceed with their research.

“Exactly for this reason that it is perfect! Imagine the amount of secrets there are in this thing!” Bakugou said almost jumping out of the chair, he was really excited today.

“Well, you have a good point” Izuku shrugged and looked back at the laptop.

While the old laptop turned on, the boys were getting close to the screen, their faces almost sticking to the object.

But all the excitement disappeared like magic when on the screen the words “Password” appeared.

“You said that it didn't have a password!” Bakugou screamed at Izuku

“But it didn’t!” Izuku clearly remembered seeing Ranpo using the laptop, there wasn’t any password.

“Well, clearly there is one now!” Bakugou said, looking away with his arms crossed.

“He must have put it in today” Izuku signed, of course, Ranpo would know what they were planning.

“Damit!” Bakugou pressed the keys angrily, Izuku was certain that he had some kind of angry problem 

“Well, we could try to guess it?” Izuku suggested taking the laptop out of Bakugou's hands before he accidentally destroyed it. 

“That will be hard” Bakugou frowned looking at the screen as if all the world secrets where there

“Try 123” The boys jumped when they heard a voice behind them 

“WHAT THE HECK!” Bakugou, as usually, immediately went for an attack 

“Hey! Watch out where you stick these hands!” The other boy yelled his blue eyes looking at them angrily

He looked to be their age, redhead, angry face, and using an ugly hat.

“W-Who are you?” Izuku asked surprised, did some stranger just enter his house? 

This was the moment his mom joined the room. She was carrying a tray of cookies and looked very cheerful, she loved cooking and Ranpo loved his mom cooking even more, it wasn’t a surprise she was loving to prepare the party food.

“Oh! You boys met!” She put the tray on the table in front of them “This is Chuuya-kun, he is Ranpo’s friend from school!”

Bakugou and Izuku looked at the boy confused, Ranpo had friends?? He never hung out with anyone besides them.

The boy looked at them and snorted

"I’m Nakahara Chuuya” He said crossing his arms

“Hum… Midoriya Izuku, Nice to meet you!” Izuku, always the more polite said with a smile 

“Since when does Ranpo have a shrimp as a friend?!” Bakugou, the less polite, yelled at the boy.

That touched a nerve.

“WHO ARE YOU CALLING A SHRIMP YOU BLONDE PORCUPINE?!”

“AH?! AT LAST I DON’T USE A UGLY PIECE OF CLOTH AS HAT!”

“AHN?????? LET ME SHOW YOU WHO HAS AN UGLY-”

Izuku looked around desperate for help, but his mom had already left to check on the cake, and now he was between two yelling boys

Argh, damn it looked like he had to do something before Bakugou started with the explosions, he was tired of having to clean the destroyed furniture

“Look, Ranpo’s here!” Izuku pointed to the door, immediately both boys stopped to look at the empty space in front of the door

The both looked back at Izuku angrily

“What was that for nerd-”

“You two have to stop shouting!” He said shutting Bakugou up, wow, it actually worked this time! He looked back to the red haired boy “Are you Ranpo’s friend?”

His browns frowned and he snorted again

“Me? Friend of that shit face? No way” Nakahara said, looking at them as if they were stupid.

“Then what the hell are you doing here?!”

“Don’t shout back at me! It was your mother who came to talk with my parents and force me to come here!” 

“But you know Ranpo, right?” Izuku ignored how angry Kacchan was and looked excited at the boy, they didn’t have an idea about how Ranpo was at school since the security there was pretty rigid, this was a chance for information!

“Hum, yeah, he’s my rival” Chuuya said confidently 

Oh, bad choice of words Nakahara-kun…

“I’m Ranpo’s rival!” Bakugou yelled immediately 

Chuuya looked at him unimpressed 

“You? What threat can a boy like you be to Edogawa?” 

“WHAT THE HELL DO YOU-”

Izuku signed and looked back at the laptop, this looked like it would take a while, ignoring the boys he started typing on the keyboard, what did Nakahara-kun suggested again? 123? Yeah, no way that would work…

 

Welcome Great Detective!

 

Fuck, no way that was…

“He would've guessed you guys would have thought it was something hard” Nakahara said behind him, both the boys had stopped shouting and were now looking at the laptop.

“That was unexpected” Izuku said

“No shit” Bakugou huffed, picking the laptop out of Izuku’s hands.

“What are you guys looking for anyway?” Nakahara jumped over the couch sitting at Bakugou’s side.

“Anything that help me to destroy Ranpo” Bakugou said clicking on the folder icon

Nakahara laughed at him

“Yeah, as if you could” 

“SHUT THE-”

“Please, stop cursing!” Izuku yelled at him, his mom probably would start hearing them soon, cake only could distract her for a time.

“Look here brat, it is cute that Edogawa found some stupid puppy, but I’m the only rival he needs” Nakahara said, looking condescending at Bakugou… Yeah, that was bad.

Bakugou launched himself into Nakahara, leaving the poor laptop to fall on the ground

The boys stopped fighting, all three of them looking at the broken laptop on the floor.

“Look what you did!” Both Bakugou and Chuuya yelled at each other

“My mom gonna kill me” Izuku signed

Nakahara crouched down to look at the object

“I think it just cracked the screen” 

“AS IF THIS WAS ANY-”

“Ok!” Nakahara got up, picking the laptop carefully “You two hide this and distract Ranpo, I will buy a new one”

“How are you going to buy a new laptop? This one looks expensive” Izuku asked. He thinks no matter how much he saved, he would never be able to buy one like this using his allowance.

“I will, don’t worry” Nakahara said leaving the house quickly 

“Can’t believe he’s just going to leave like this!” Bakugou yelled angrily “He’s the one who broke it!”

“Well, that was kinda your fault…”

“Shut up deku! No one asked you!” Bakugou pulled the laptop out of Izuku's hands “Let’s hide it!”



It didn’t take too much for Ranpo to come home, His grandpa went to the kitchen looking for Inko while he went immediately to his room carrying a lot of presents and then went back to the living room.

“Hey! What are you guys doing?” Bakugou and Izuku tried to look as unsuspicious as possible, not doing it very successfully. “Better asking, what did you guys do?”

“W-What do you mean, we didn’t do-”

“Izuku ate all the cookies” Bakugou said and Ranpo immediately look at Izuku as if he had killed his dog

“Wait, really?”

“D-Don’t worry, mom is making more!” Why did Bakugou have to toss Izuku under the bus? 

“I hope so!” Ranpo said, throwing himself on the couch.

The boys stayed in silence, Ranpo looked to be just staring at the roof. Chuuya probably would be back soon and the boys could put all this behind them…

“Did you guys break my laptop?” All Izuku’s hope died immediately.

“How the hell can you know it?!” Bakugou yelled

“The laptop charger is there” He pointed to the power plug, and indeed the laptop charger was still there “Nakahara obvious was here, but isn’t anymore, and you guys look really guilty”

Izuku immediately bowed at Ranpo

“S-SORRY RANPO!” He cried “We shouldn’t have picked your laptop in the first place! We are really sorry”

“Yeah, sorry” Bakugou said

For the boys surprise Ranpo actually laught 

“It’s fine! This means Chuuya will have to buy a new one for me!” He said happily “But if you guys are really guilty, you could go pick some sweets for me, yeah?”

“I hate you” Bakugou said and Ranpo laught even more

Izuku would go get the sweets anyway, Chuuya would come back one hour later with the new laptop, and Izuku still doesn't know where he got it. In general, it was a better day than Izuku expected.

And he got something new to put on the notebook… “Nakahara Chuuya” what could be his quirk?



Ranpo’s mentor

Izuku shouldn’t be surprised that Kacchan’s next idea would go from stealing to stalking, today was sunday and normally Izuku would have been organizing his notebooks, maybe researching on a new hero or even reorganizing his All Might merch, but no, Kacchan had to drag him out of his house to the cold streets with the sole purpose of following Ranpo.

Two years ago he would never have thought that his feelings for Kacchan would have gone from afraid to annoyed, but here he was, hiding against a car while Kacchan used his toy binoculars to observe Ranpo.

“He isn’t even that far” Izuku complained, putting his gloved hands back in his pockets “It’s too cold, can’t we do this when summer comes?” 

Kacchan rolled his eyes and put away the binoculars 

“We could have done this years ago if you had told me Ranpo goes out every sunday earlier” 

“I didn’t know! I don’t usually leave my room on sundays- And he usually doens’t even know how to walk to the end of the street!” Izuku defended himself as they moved crouched down so Ranpo wouldn’t spot them.

“If you were my sidekick I would have fired you!” Kacchan said and Izuku huffed annoyed

“If you were my boss I would have resigned” He murmured, shutting up as soon as Kacchan looked back at him with an angry stare “Hey look- Ranpo is entering some place” 

They watched as the boy entered some building, it looked like a business edifice but with an old architecture, very different from the rest of Musutafu.

“Is that a hero agency?” Katsuki raised his eyebrows as they abandoned the hidden place and walked to the building. 

Izuku springed, excited as he picked his notes, he didn’t know there was a hero agency so close to his home. Who it was? Must be a new or underground hero- In this part of the city? Underground for sure, but with a building tall like that it must be someone with money-

“It’s called The Armed Detective Agency” Katsuki said pointing at the stone plate in the building’s wall “That’s an ugly name, who would call a hero agency that?”

“I don’t know, we can google it later” Izuku said, moving to try and see through one of the windows, finding just an empty office. “The lobby must be on the higher floors”

“What is Ranpo doing at a hero agency?” Katsuki put a hand on his chin and then suddenly widened his eyes “You don’t think-”

“Would it be-” Both the boys stared at each other

“He wants to be a hero?!” They yelled at the same time



They went back home after that, sitting in silence in Bakugou's home as they waited for the computer to turn on. Neither of the boys wanted to believe their theory, after all, Ranpo had never shown any interest in heroes. 

“He can’t be one- He is quirkless” Kacchan stated as if a fact and Izuku shifted uncomfortably, this was indeed a very delicate topic for them. Since Katsuki started hanging around him again Izuku tried to not mention his dream, afraid of what his reaction could be.

“If Ranpo wants something I'm sure he would do it” Izuku huffed, with some determination in his eyes. His stomach hurt with anxiety, could Ranpo be a hero? With his intellect, Izuku had no doubt- But again, he was quirkless- If Ranpo could be a hero, does it mean Izuku could too? 

“Not even him can break the laws of the universe” Katsuki murmured, typing on the computer 

“Quirkless discrimination isn’t a law-”

“Shut up” Katsuki said hitting him in the head and then pointing at the computer “Look what I found”

Izuku decided to ignore Katuski’s behavior and read the google results. According to the information, The Armed Detective Agency was an underground agency, owned by a hero called Fukuzawa Yukichi.

“Not even a hero name? This guy must be boring as hell” Kacchan said crossing his arms

Izuku however was excitedly going through the man’s heropedia, there was little information, what was expected from an underground hero, but Izuku almost entered in shock with the next information he read.

“Kacchan!” He yelled and Kacchan almost fell out of his chair

“What are you yelling for?!”

“He studied at the 1-A at the same time as All Might!” He said pointing excitedly at his education years 

“Wow, so there are losers even in UA” Katchan said given a briefly look at the article

“You don’t even know him” Izuku rolled his eyes 

“He isn’t famous is he?”

“Not all good heroes are famous you know” 

“The Hero Ranks are exactly how we know how good are the heroes” 

“Urgh, I can name at lat 20 heroes who aren’t even in the ranks but are strong as-”

“Stop nerding ok, we are here to investigate Ranpo” Kacchan interrupted him and picked up the Ranpo Notebook “Why would he hang out in a hero agency?”

“I don’t know- They are a detective agency right? Ranpo does say he is the best detective in the world” Izuku said resting his head on his hand

“I thought it was just another weird thing he did” Kacchan shrugged 

“I am the greatest detective in the world” Ranpo said and both Both Izuku and Kacchan jumped in fright. 

“WHAT THE HELL ARE YOU DOING HERE?!” Kacchan yelled, his hands immediately starting to make sparkles  

“Calm down” Ranpo said putting a wet cloth in Kacchan’s hands “Your mother let me in”

“Huh- Aren’t you usually busy at sundays?” Izuku asked trying to fish for answers, it was too early for Ranpo to have headed home.

“I saw you guys following me and wondered what you’re up to” He shrugged, opening a lollipop “You guys are really horrible at this stalking thing, you know?”

“Shut up” Kacchan huffed getting up toss the wet cloth away 

“Sorry for that” Izuku said putting a hand on the back of his neck “We were just curious”

“I know” He smiled at Izuku “Do you want to meet him?”

“Huh?”

“Fukuzawa” Ranpo said pointing at the computer screen 



This is how they ended back at that tall building, Izuku with his autograph notebook in hand and Katsuki with an angry stare. 

“Come on! You guys are so slow!” Ranpo complained as they went up the stairs 

“Ah- I’m nervous! I have never met a hero this close!” Izuku couldn’t stop shifting around uncomfortably 

“It’s not even a known one!” Kacchan complained 

“He is the best in the whole world!” Ranpo said proudly as they arrived in the last floor 

“That’s All Might” Both Izuku and Katsuki said at the same time

“Nope! Boss is the best!” Ranpo said, opening the door and carelessly  walking in “Yo! I’m back!”

Inside there was a big office room, practically empty if not for a girl and a man dressed in traditional clothes. Both were looking at something on a computer.

“Hey Ranpo” She smiled and then noticed them “Who are the kids?”

“You’re a kid too!” Katsuki yelled at her, she looked a little older than them but still a kid

“That one pretty brat, isn’t he?” She pointed at Katsuki, which only made him angrier.

“Right? He is so funny, just like a chiwawa!” Ranpo dodged the blow that came in his direction, just laughing in good nature 

Fukuzawa sighed and Izuku looked up to watch the man, he looked like a serious person, his face even being a little scary. He gulped as afraid as he was interested to know his quirk. Trying to be brave he approached the man in small steeps

“Please, could you give me an autograph?!” He bowed down showing the man his notebook

The silence fallowed

“Izuku stop asking for an autograph to such an unknown hero!”’

“HAHAHA You’re famous here boss!” Ranpo laughed

“I have to admit it is pretty funny” The girl said

Izuku face was red from embarrassment 

“Sorry, I didn’t-”

Fukuzawa sighed again

“Don’t mind them” He said, picking the notebook and quickly signing it “Here, dream big and be brave!”

“You even have a catch phrase!” Ranpo laughed hard but Izuku could only smile at the man.

“Thank you!” He said 

“Hey! Give us answers! Why are you coming here every week?!” Kacchan bored with the following events went straight to interrogation 

Ranpo blinked at him

“I work here!”

“BULLSHIT!”

The girl held back a laugh and Izuku sighed, he watched as the boy tried to attack Ranpo who flawlessly dodged him till making him stumble in the carpet and fall down.

Izuku turned to Fukuzawa who was just watching the scene with a small smile, he gulped and moved his feet nervously.

“Fukuzawa-san…” The man turned to him and Izuku had to look away, his heart beating hard “Do- Do you think I can be a hero? Even if I’m quirkless?”

Fukuzawa blinked and Izuku face burned red again, but for his surprise the man patted his head 

“Of course, anyone can strive to help others- Quirks don’t make someone a hero, their willpower do” He said and Izuku could only nod, his eyes burning a little while he held his tears.

 

No one had ever said he could be a hero before.
