Author's note :

So... Well thanks for the reviews people ! It is very nice of you!

A little explanation on Izuku's quirk.

Endgame : Emitter quirk.

The user can summon what is written on cards. However the quirk has severe limitations:

-The card must be a real, official card.

-The used cars is destroyed.

-The more powerful the card, the bigger the toll.

As an example, Izuku summoning an Exodia would not destroy the world and a real powerful enemy could survive the attack. However Izuku's brain would most likely explode in his current state.

The reason why I put the limits ? Because it is funnier that way and I am not good at writing OP character.

Chapter 3

Katsuki thought. He had a Deku and a girl with snake hair and two unconscious dumbasses. If he let them be, Izuku would be in trouble. Teachers wouldn't care that Izuku helped someone. It would be proof that Izuku was attacking "normal" students. Same for Snake Hair. She was a younger girl, as she was smaller than him or Izuku.

"If only you beat them with a quirk, that would have been easier to explain." Katsuki sighed as he knew the teacher would invent some bullshit to annoy the green bean… Who seemed uncomfortable. His feet did the thing when he had something to hide. Note to self. Kick Izuku in the face later to have the full story on that later.

Let's prioritize for now. If they found it was Izuku who was responsible, it would be bad. Deku's idea to hide them was not bad but if they did that, the bullies would wake up and cry to the teacher.

A small smile appeared on Katsuki's face.

"Well, I guess the solution is even more violence"

He said as the explosion came through his hand as he punched the two extras down in the face, hard, several times each.

"Now, if the teachers want to have a word with shitty De… Shitty Green Hair and you, Snake hair, they will also have to punish me."

"... You don't fear that they will punish you? Also, that's quirkist, asshole." Ophidia responded, as some of her hair hissed at the angry blond boy, who flipped the bird.

"I have done worse and gotten praise for it. Also, I say that to everyone, not just you Snake hair."

"The sad thing is that he's right. And don't worry about him. He's bad with names and things like that. Also," Izuku pointed to the two cringing boys on the ground, " they will say that Katsuki beat them down. Saying it was me or you would destroy their rep. By letting Kacchan take credit…"

"YOU TAKE TOO LONG TO EXPLAIN. BASICALLY, THEY ARE BITCHES, AND THEY'LL SUCK IT UP. So either they try to say Deku did it alone, but the burn will give away I was here… Not to mention I'm going to tell people I beat them like bitches." Katsuki said, having found a foolproof plan to protect the two others.

"Kacchan! Language! Otherwise, I'll tell Aunty!" The green-haired boy warned his friend.

"... Deku, do that and I tell Aunty you broke arms." Katsuki threatened back with a somehow proud smile, as if approving.

"They aren't broken, just dislocated!" Izuku tried to justify himself, failing to understand he was just digging his tomb.

"That… Is darn cool." Dammit. Katsuki found that even cooler. Wait, was it bad or good? Izuku was quite in a conundrum, muttering more than usual his process of thought, which wore on the already thin nerves of his "friend".

"... Are you a friend or what?" Asked the young bystander, feeling almost like an intruder between the both of them… Despite being the first at the scene, being, you know, the victim.

"YES!" "NO!" said at the same time the two boys, who then glared at each other.

"Boys are weird" Concluded Ophidia while letting the two aspiring heroes argue with each other about their friendship.

—-

However, their plan was not perfect: while Ophidia was indeed off the hook, many people stared at Izuku and Katsuki, all while the green bean was trying to calm his nerves with his card tricks in his hands… Katsuki was still trying to understand how he could make them dance just like that in his fingers.

Well, while he tried to understand that, the word had passed. Katsuki was not cool anymore with bullying Izuku. Sure, no teacher was after them, but Katsuki could feel all his privileges being revoked one by one.

No more missing classes, his teachers warned. It annoyed him a bit, but somehow, Katsuki felt it was worth it. They were all extras, and it was his last year here.

Also, now that Izuku was less spineless, he was almost worth being a sidekick. His sidekick. He just needed a few more pushes, and he also owed Katsuki a few explanations, too.

As for Izuku, well, he was eyed differently, not with fear, as the two first extra downplayed their defeat by saying it was Katsuki who beat them. However, Katsuki was more feared than loved and if Izuku was his friend, then he was a weak point, too. The angry Pomeranian knew that, as it was one of his reasons to distance himself from Izuku with the others.

Now, Izuku would have to watch his back.

"I will not protect you," Katsuki said as they went back home together, for the first time in years, "You need to get them off your back, by yourself."

"You are making them not attack me by being here, you know?"

"So, that is how you see yourself? As my sidekick, helping me, but under my protection?" Katsuki replied to him, but it was a turning point. By winning against those two dumbasses alone, Izuku was not useless. His analyzes were always on point and now he knew how to defend himself a bit. In short, Katsuki will let him be his sidekick. However, he had to listen to Deku saying so much he wanted to be a hero, not a sidekick, that he wanted the green bean to say it himself..

His point for once got across Izuku. Under his hair, the young man thought a lot. His quirk was impractical… For now. And somehow he felt something. If he said yes, right here, right now, Kacchan would protect him. Izuku would help him, without a doubt, to be the next n°1. Izuku could be the next Nighteye. That was his first dream when Katsuki got his quirk after all.

But a little voice in the back of his mind made him remember the discussion with Mr. Compress. What kind of hero did he want to be? Did he want to be just a sidekick?

While they walked back home, Izuku knew, his choice, here and now, would shape him.

"No. I want to stand by myself." said Izuku with more pride than he had the day before, invigorated by his fight.

Katsuki stopped in an instant, before groaning, preparing for an explosion to make his point across, when Izuku continued.

"You are right. I can't continue to just say I want to be a hero doing nothing." The blonde boy did not expect that… and for once, he let his friend speak, his sparks disappearing.

"... Is that why you were that angry at me?" Asked Izuku, as his friend tsseked at his friend, avoiding his stare. Saying that Katsuki had trouble making his point come across as saying that the water was wet and it was also somehow amusing that someone so direct was sometimes so ambiguous.

"Try to guess, Deku". It made Izuku think more. He then smiled at his friend with that damn smile, his big sunny smile. One reason he would have liked to have him at his side.

"Thank you, Kacchan. Don't worry, I'll get them off my back. Alone, I mean."

"Without a Quirk? That is going to be fun." Katsuki snarked a bit… But his smile showed he thought Izuku could do that. When he wanted to, Deku was quite scary and Katsuki knew how he could be feared enough that no one would mess with him.

It was then that he saw Izuku squirm a bit and Katsuki pinched the bridge of his nose.

"Deeeekuuuuuuuuu…." He groaned, an explosion appearing in his free hand…

"I only got it recently! And if I use it too much, it can really hurt my brain!" Izuku spilled out to his friend, who then stopped his explosions and thought about it. Izuku would never lie about something that was important to him, hell, Katsuki helped him when they were young to put him in a "dangerous" situation so he could awaken his quirk. If Izuku said he had a quirk but it hurt his brain then it was most likely true.

"... You have to use cards to use it, I guess? That is why you keep playing with them?" Bakugou speculated a bit, as you could say whatever you wanted about his temper, but Bakugou was at the top of the class with Izuku for a good reason. He was not dumb and could connect dots when he saw them. Especially now he had figured the missing part of a puzzle bothering him for a few months now.

"I can summon what they print on cards, but it destroys them and since I developed it very late, it can hurt me if I use it too much."

"So, you can summon an Endeavor with your cards?"

"That would knock me out and I would need medical attention." Izuku did not deny the possibility of Katsuki's frustration.

"... Fuck, that'd be pretty useful if you kept training it. That is why your step-dad teaches you to fight without quirk, so you don't die?"

"Wait my…" Izuku said, then trailed off, not wanting to think about such a possibility yet, especially knowing the secret identity of Atsuhiro.

"Deku, my mom is preparing designs for your mom's wedding dress when that will happen and he comes to see Aunty with flowers." Bakugou had a point and his face showed he had no fucks to give about his friend's sensibilities. His friend, who needed a reboot that Katsuki applied by hitting the back of his head, as Izuku noticed something else.

"Wait, you know he teaches me how to fight quirkless?"

"Izuku. Your mom told my mother that you had a teacher. I saw you with him, and I know when someone throws a good punch. You never learned to do it before, so he taught you."

"I don't punch" Izuku tried to tell what he did.

"Still super damn cool. You saw how his arm was limp? I'm surprised you had the guts to do that."

Katsuki thought he couldn't be surprised anymore. He thought that Izuku would almost vomit when realizing what he did. Instead, he had an Izuku who laughed. A lot. With a tiny part of nervosity, the exploding boy asked,

"You are alright?"

"Katsuki. My teacher's idea of breaking my idea of not hurting others had been to disjoint my bone and borderline torture. I also learned he knew French because he made a terrible pun with it and the Deku nickname you gave me."

"... What?" A reasonable reaction.

"You are called Deku? That is perfect, because "C'est exactement ce que tu vas recevoir"" Said a flat-faced Izuku. (For those wondering, we pronounce in French Deku as "Des coups" [Some hit]. Compress said that Deku was going to get hit because of his nickname.)

"... I'm going to take that one just for the reference," laughed Katsuki, after understanding the joke and being able to appreciate that kind of violent humor.

"Kacchan… Well. Still. To go back to what we were saying. I want to be a hero and I understand why my teacher told me I had one month to make them scared straight. I think he thought violence was my solution, but we both know that…"

"Teachers are going to bitch about it and those extras will never fight you with less than three people. If I understand correctly, you only won because you had that surprise kick in."

Izuku nodded. Kacchan was good in a fight and in analyzing one. It was a good idea.

"It is going to be fun. Because I know a way to terrify all the extras."

"But you will not tell me because you want me to suffer." Deadpanned Izuku, looking at his friend who had this smug smile.

seeing Katsuki less angry and smiling at him just like old times… Well, it was nice. Nice to see he could be trusted, if only a bit. Katsuki being delicate was not possible according to the law of the universe. Izuku would settle for his childhood friend, not being an asshole. He still surprised Katsuki a bit with his knowing smile.

"That isn't a problem. I know someone who can teach me how to scare people straight."

—-

"... So that is why you're asking ME, to teach you how to scare people?" Tomura was pinching the bridge of his nose while Izuku told him about his school situation. 'At least the kid's standing up for himself.' the older man-child thought. It proved he wasn't an NPC. More like a character he wanted for his team, with the proper effort.

"Tomura. You are in the top 3 of the scariest people I know. It includes actual supervillains like Moonfish." Said Izuku semi-seriously, who was pretty conscious that his… Sort of friend? Wasn't the nicest guy around, though he was a lot of fun and a skilful player.

"It's nice to know that I'm on par with a freaking cannibal with only my smile," Tomura said as he chuckled, amused by the fact Izuku did not know his past or his plans. "You know what? Beat me once today and I will help you work on it. Deal?"

The trick here is that in all the time they knew each other and the dozens of games they've played, Izuku won only two times. Mostly by luck and the fact that Tomura used handicaps.

"That's fine by me!" Said Izuku with his usual smile. Saturday was his day off training. Mr. Compress said that too much training was a thing and seeing people would help him have more confidence. It was… quite true. Staying over one afternoon playing with a Tomura glaring and smiling at you was an exceptional training to ignore his fear.

Izuku was good at judging character and knew more about Tomura than what he let slip.

For starters, Tomura's habit of keeping a pinkie on his card was a sign that his quirk was a five-point activation one. One that's annoying or powerful.

Second thing. Tomura was a rich sheltered kid with a nanny. He deduced that purely from his clothes and his spending habits. Izuku had to tell him it was not normal to buy over four thousand yens worth of cards each week. Hell, most people couldn't afford that budget as a monthly one.

Third, his nanny and his parents sheltered him and lived in their own world. Seriously, otherwise, they would have made him clean his act and his appearance way earlier. Were they blind?!

Fourth, Tomura thought he had everything he needed and did not go outside shopping.

Fifth, while smarter and more intelligent than most people credited him for, Tomura primarily sought fun.

Sixth, he was way too prideful.

Seventh and last point, I swear.

Tomura did not play well when he got emotional.

So, at first, Tomura was… Well, winning, as usual. He refined his tactics against Izuku, who did not have the same money as him to improve his deck drastically. So, while he knew that theoretically, Izuku could manage a win, Tomura knew it was more of an error on his part than anything else.

If a secondary character wanted his help for his side quest, he better had to win his approval and prove that he was useful. As of now… Well, Izuku was fun. He was not dumb too, being able to understand Tomura when he spoke video games. He also advised Tomura a few times on old video games.

However, despite Izuku putting up a valiant fight with his Vigilante Deck, one of the few capable of denting his Villain Deck around Destro, Tomura knew he almost finished his win conditions for his final combo. All he needed was a last card.

That was at that moment, however, that Izuku truly attacked.

"Oh, that made me think, Tomura. I have a gift for you." Said Izuku with his big gentle innocent smile. Tomura could tank it, being… Well, Tomura, but was not prepared when Izuku pulled something from his backpack. It was… Gloves? Why was it missing three fingers?

"... NPC? The fuck is that?"

"Artist gloves. Just… Believe me, ok? Put them on."

Half thinking of dusting Izuku if it was as dumb as Tomura thought, he did it. Izuku was too… Well, Izuku, to be a danger. At most, he was an idiot.

Now, Tomura had equipped the strange gloves. He looked with blood in his eyes Izuku… who grabbed his hand in his own with his innocent smile!

Shit! Tomura was only half-serious about dusting the kid! He had to make it stop before…

Tomura looked at Izuku's hand, which did not decay. Izuku was fine and smiling.

"See? I'm fine!" told the young hero to the aspiring villain.

"... You know about my quirk?" Tomura never told him for obvious reasons, as his quirk was deadly as hell. Most people would categorize him as a villain and not think twice about it.

"That it is most likely a five-point touch-activated quirk and certainly a destructive one? Easily! But it seemed rude to ask you about it!"

"Can you stop grabbing my hand and explain, Izuku?" Said Tomura, as Izuku was still hand to hand with him. Not that he didn't reassure him about… Wait. Was he caring about someone else's well-being? Definitely not. He just did not want to be kicked out of his favorite store for accidental death. Yes. Definitely that.

Still, Izuku, like a good follower who entered forcefully his party, explained.

"Those are artist gloves. If just one finger is covered, you don't risk activating by mistake your quirk! It seems like you can't deactivate your quirk, so if you use that, you don't have to worry about it!"

"... Izuku, you know you could have just given me that to max my affection and I would have trained you in the way of villainy?" Stated Tomura, seriously… while testing the effectiveness of Izuku's gift by grabbing with all his five fingers a card. Izuku did not stop to smile. Also, the blue-haired villain couldn't stop thinking about it. How the hell did Izuku deduce all that?

"... No, that isn't the same." Said the young man, while playing his turn, and Tomura distractedly answered in kind. "It has to be fair, not a bribe." Playing mind games was fair in Izuku's book.

—-

Somewhere, as Mr. Compress was stealing incriminating documents from a corrupt CEO, he also felt pride in his heart. He knew Izuku made his first step in the way of craziness.

—-

Missing three turns by being able to hold things for the first time in his life without having to worry about dusting them proved to be fatal for the game.

As in "Izuku summoning his Eraserhead on the field, neutralizing his Boss and killing him by doing a nasty Crawler/Celebrity combo." An excessively hard-to-do combo that Izuku barely did because he was too disturbed.

Tomura stared nastily at Izuku… Before doing his creepy smile. Except Izuku could, somehow, feel a sense of pride in it?

"Izuku? Why do you even need my help?"

What?

"You guessed my… weakness. You made a plan to work with it then executed it with a freaking smile on your face. If you wanted to be a feared villain, all you needed to do was do it while explaining it clearly. Like, no muttering. Speak up clearly." Explained Tomura calmly. "There isn't a thing scarier than a high-level player explaining to you your weaknesses while acting on them and you know you can't do anything to stop him. Even worse: if he's really good at it, you also understand he can do that whenever he wants."

Izuku tilted his head adorably with his puppy eyes. "... But… People find my muttering creepy, not scary?"

"Because they can't understand the things you deduced from them. Hell, just for fun. What do you know about me?"

"Tomura Shigaraki, around 20 years old. Homeschooled. Very sheltered. Somehow have access to video games older than both of us, from the pre-Quirk era. His guardian must be some kind of really rich nerd."

—-

Somewhere, AfO somehow felt like someone dissed him. Oh well. Time to re-watch (and by re-watch, he means re-listen) Star Wars, Episode IV of course…

—-

'Has a rich guardian and a nanny. Has been mistreated by the hero system. Very smart, but I feel like he'sn't as educated as he should be. Does not have many friends aside from me and no girlfriend. He uses shampoo made locally around the Kamino Ward. Excellent one, but since he doesn't care about his face, it's probably his guardian who has some great taste."

—-

Somewhere, Kurogiri nodded.

—-

"Ok, stop right there. You deduced that in how much time?!" Tomura was dumbfounded.

"... Ten minutes?" said a sheepish Izuku. Wasn't it good enough?

Holy crap. Izuku was a high-potential secondary character. A Heroic one, but what did Sensei say? "The best kind of help a hero can bring you is the help he doesn't know he gave to a Villain. As a bonus, you can always corrupt him later when you reveal to him how your plan couldn't have worked without him!"

Tomura smiled. Yes… The plan was foolproof! He was going to get a second strategist on his team and it would be Izuku! Nothing could go wrong with that plan!

—-

Everything went wrong with that plan.
