Izuku did end up thinking about all of it. Maybe a little too much.

But after spending so much time avoiding the question of what he was supposed to do, to be, in the future, as he gave up on his hero dream, he was forced to face it all. The teachers had already taken the applications for highschools and Izuku had written only hero schools, with UA as a first choice. They would probably let students change it if there was a real need but certainly not for the quirkless kid who thought too big of himself. If Izuku wanted to try out only for heroes and he failed, society would finally get rid of him. Izuku was almost sure that the fact that he intended the school was bad for its reputation, unofficially of course. But once he had caught a teacher complaining about their pay decreasing because of the quality of the students. They had looked at him particularly nastily that day and had added a few derogatory comments during class that his classmates had enjoyed repeating as an excuse for the beat up of the day.

So here was Izuku, looking through the tabs open on his computer, trying to think of what to do.

Again, his mind was kind of split.

A part of him still wanted to try for heroism but it was such a small part of him that Izuku didn't even bother listening. It was a stupid dream and no one would take him seriously. He had seen first hand what people thought of quirkless people and what they'd do to him if he ever got the chance (but was it really one?) to join the hero course. Knowing his luck, the entrance exam wouldn't even be fair and would favor strong and showy quirks instead of something to actually test someone's will to help, if they had what it took to be a hero.

Izuku had done some research since joining the league and had seen how the heroes coming out of the biggest school tended to be the most show-off and were more willing to join social events and conventions rather than fights and investigations. Some were even downright dangerous in their endeavors, such as Endeavor (pun intended) who tended to do more harm than good once he joined a fight.

Another part of his mind was trying to convince Izuku to still do something qualified as good. All Might had talked about policemen, even doctors. Izuku was smart and could help on crime scenes and put together clues to resolve a case. He could still help, even if the impact would lessen, and this was not so bad.

But he also knew that on so many application forms, to enter schools and universities, he needed to give his quirk, to add it to the equation which would determine his life. And to have a quirk considered weak was one thing. To lack one was another.

A voice, oh so similar to Sensei's, kept telling him that he could do more, that Izuku couldn't just settle for 'not so bad', for okay and surviving. He deserved better, whatever the bullies said. He could do better and who cared if most didn't believe in him?

That was the third part of his mind. The one actually winning the fight even if Izuku's inner child was heartbroken by the decision. But Izuku's inner child was naive and hopeful, stupid in other words, he hadn't seen much of the world and didn't know what would come for him.

He would prove them all wrong. Society decided to keep him out? He would explode its walls and dig himself a place by force if he had to. They were all so set on not helping, on seeing him fail, so sure of his uselessness and stupidity, underestimating him.

And he knew that they were others like him. People whose quirks weren't fitting for society, people with difficulties due to their quirks or uprising. Powerless people because they weren't allowed to empower themselves.

Well, Izuku was going to give them the opportunity.

After spending so much time on forums who complained and accused society of turning a blind eye on their situation, Izuku had seen enough to know what was done and what wasn't. He knew of names and situations that nowhere else he could've heard about. He knew of things that repulsed him so much that he sometimes felt disappointed to be part of the human race.

Izuku still wanted to help. It was his best quality but also his worst flaw. He had always wanted to and even now, he couldn't help but feel like he still could do something about it.

Perhaps society's rejects could join force and help each other, damn the world and their rules.

So Izuku thought. He thought and a sick part of his mind liked what he came up with.

Joining UA would be a bad idea. Kacchan would go there and he would spend his days with Hero-wannabes, and, as someone who liked to think of himself as a member of a group who called themselves the 'League of Villains', that would be a pretty bad idea. But Kacchan had never been able to see past his nose, he wouldn't even realize Izuku was there until it was too late, and Heroes were known for their stupidity and their tendencies to think of themselves superior to the rest of the world. (Actually it all made sense, Kacchan would be a perfect hero by society's standards.)

Izuku ended up checking over the different courses at UA school. He knew of the hero one, the reason the whole school was known for. The place obviously had a general study one, as well as a business course. The latter sounded somehow interesting, what better than the economy to make a society fall? Money, the greatest problem, the greatest weapon, always.

But what really picked his interest was the support course.

He had always thought of support items as useful and priceless to heroes who were willing to use them. He had 'designed' a few to help potential heroes after seeing their quirks, the only problem was that Izuku knew what he wanted with them, but not how to make them.

He would talk about it with Sensei, who surely would have some idea about it.

Plus, he was right when he said that UA was a key in the hero world. Teachers there were pro-heroes themselves, they raised, educated and trained the next generations. But mainly the school principal was the not-so-known pro Nezu, one of the rare case of animals developing a quirk. He was highly intelligent and was often helping open-cases from all around the world to find closure.

If the League would ever get popular for their deeds, it would be important to have intel from inside the school.

One stone, two birds. Perhaps three if Izuku managed to destroy the reputation of a certain exploding boy...

On top of this, Izuku was true to his words when he said he wanted to analyze the others' quirks to Sensei.

He had already prepared something for Kurogiri, adding some ideas to the one in his notebook and organizing them to give them directly to Sensei.

He worked a lot on Shigaraki's. His quirk was as fascinating as it was dangerous. Named Decay, Izuku had been right to believe the quirk had an non rewindable effect on things touched with five-fingers touch. It literally turned everything the man touched into dust.

Izuku had started with the effect. He wanted to know if the effects could be controlled, spread, decaying in other components than dust. If the quirk simply sped up the process of normal decaying or was one those abnormalities of quirks that couldn't be explained like that. If the effects were different depending on the material of the subject, maybe different from organic to non-living things. He also tried to think of ways of preventing the quirk from activating without having to wear the drawer's gloves. They didn't take an eternity to take off but in a fight those precious seconds could be deadly. He also questioned the effect on Shigaraki's skin. Because apparently the quirk didn't have any lethal effect on him since it was his quirk but it didn't seem harmless either. Was Shigaraki more resilient to the effect of his quirk or was his body made to not be affected? On the side, Izuku wondered how he found out about his ability to not dust himself and what would have happened if he, in fact, didn't have this counter-power. Izuku also added notes and ideas on how to, potentially, get rid of this irritation using the quirk itself.

Of course Izuku wasn't sure. It wasn't something that you learned in school nor that you could easily find on the internet but the science behind the quirks was, somehow, rather easy. Like everything else it was in your DNA, if Izuku had the materials for it, he'd like to pinpoint where and which genes could decide on the quirks and the effect on it and whether or not mutation had happened on the subject's DNA to accommodate the use of the quirk. He could compare it exactly to his own DNA, as he was lacking the gene of quirks. In it, he could maybe find some things to help him create means to annihilate or reduce the effects or permit the creation of products and items to help the lives of those whose quirks did not permit to use normal items in their everyday lives. Such as Shigaraki, normal lotion wouldn't probably work on him due to his quirk resistance, but if Izuku could find what exactly made Shigaraki's skin like this, he could find what to change in the lotion to actually help him.

That's how he ended up once more at the bar, asking questions to his friend in front of the screen so Sensei could hear as well.

They were testing out the limits of the quirk, a pile of dust rising under the man's hands and a pile of plate reducing quickly. Izuku was trying to figure out whether or not the quirk could be controlled even without the gloves. He had asked the blue-haired man to try and dust only half of the plate, and watched him fail on many occurrences.

"It's not working. That's not how it works. It decayed Mon and Hana, and everyone else and it will decay the plates. The stats of the weapon won't change just because we want them to."

Izuku blinked a few times, astonished. He didn't know who Hana, Mon or whoever else were but this sounded like his friend had killed people with his quirk, unintentionally Izuku would say, and was pretty set on the effect of his quirk since then. He didn't know how to answer or what to do with the information.

Thankfully, he was saved by Sensei.

"Well, Tomura, if you wished to share, you could have explained more. Do you want some help?"

Shigaraki, who was furiously scratching his neck beside Izuku, didn't seem at ease. Izuku wanted to grab his hands and stop him from hurting himself more but he figured it wasn't necessarily the moment and until his project was achieved and his magical potion made, he didn't have any actual solution for the guy.

After some time, his friend nodded and Sensei began to talk.

"Tomura here discovered his quirk during an unfortunate event. His quirk manifested after a fight with his so-called family, a group of brutes and heavy handed people who didn't know how to take care of their child. He.... Lost control of his quirk. Decay erased a good part of the house. After that, Tomura went to search for help. But none was given to him. He begged people on the streets and heroes to help him, a four-year-old boy, but none dared and he was left alone, homeless in a world that didn't care about him. That's when I found him, and decided to offer him a chance to show his worth. So perhaps you should postpone this little training session and relax for a bit."

The dismissal was clear, Shigaraki stood up and left to sit in his booth, clearly wishing to be left alone. Izuku was anxiously fidgeting with his notebook, still open on his friend's page. He felt bad for awakening such a memory.

But he also felt angry. He understood why Shigaraki held people, and heroes in particular, in such low regards. He couldn't imagine what it must have felt like, abandoned, driven by fear and maybe guilt after what happened, having no idea where to go, what to do with himself. Of course he had turned toward the heroes. It was their job to know! To help! And they didn't move a single finger to help.

It was terrible.

And Izuku felt terrible. He couldn't believe he had wanted so badly to take part in a system such as this one. That he had spent money for the people who cared about no one but themselves. That he had cheered on them as they defeated the villain.

But who were actually the villains? They were always painted as the bad guy, as those ruthless individuals who thought more about themselves than others, who wanted others in pain.

Izuku wondered how many couldn't get enough money at the end of the month because no one was willing to employ them because of their quirks. How many had been abused, told they were useless or a monster. Izuku wondered how many had a choice.

He turned toward the screen, certain that Sensei was still listening.

"I decided that I would still go to UA." He let the words hang a little, not sure how to explain his thoughts. "They have a support course and they have the best resources. I'm sure being able to use it could help me in potential plans for the future... And I figured that having someone inside could help... our cause."

"And what would that cause be, Izuku?"

"Our society put Heroes in some sort of pedestal, their egos are fed, they forget that they are just as human as the rest of us. They forget the meaning of the word hero, they taint it. They give up on so many people because they don't fit in their so-called perfect society. I want to help those people. I didn't deserve to be put aside and stepped on and neither do they. Heroes think their all mighty but they have weaknesses just as anyone else. It don't know what is your goal. I don't know what is Shigaraki's is. All I know is that you have ressources and that we're on the same side. That's my cause."

Izuku could hear the low mumbles of Shigaraki and his game, Kurogiri's coffee machine bubbling slowly, the light flickering in the next room. His heart was beating fast, but anger filled his heart and a strong desire of revenge occluded his other thoughts.

"Well, that certainly is interesting. I will help you in your endeavor, Izuku. I never lied when I say I thought your brain could do magnificent things, and I am so glad you decided to join us. Tomura needed the company, we both needed your intellect and you seemed to need us just as much.If you wish to join UA high school, and their support course none the less, you should start training for it now. Do you have any idea of what could be of use for you?"

Izuku had not yet thought of it. He knew he didn't know much of machines and technology but support relied heavily on it. He said so to the man. He needed to learn how it all worked, how to create and link and make it all work. He rambled a bit on his idea to use biology to control and help a quirk function the way it was meant to but he didn't know how.

"And I'd also like to learn how to code. Hacking."
