AN: The MC has some parts of their personality based on mine, but not all of it.

Chapter 1:

I never expected to get isekai'd. And certainly not into My Hero Academia. I mean, I guess it's not that bad, could have turned out way worse if I got reincarnated into Naruto, from which I know the most. No point to dwell on the universe choice however, since I got a life to live. Well, I will once my tiny baby body grows a bit.

I should definitely start planning though. Like, the important things: should I involve myself in the life of the protagonist? If anime logic still applies, then probably yes since I think most of the characters from the main class didn't die.

Plus I wanted an adventure. Being given a second chance, I wanted greatness, excitement, and if I was guaranteed to live through, it was even sweeter.

Looking at it like this, it really sucked that I didn't know much about it. I know the general gist of it, perhaps the first couple arcs, but reading villain!Deku means I've got only second hand accounts to draw from, not to mention that I can't even be sure of their truth.

Well, I at least read some wiki pages.

I can't wait to get a quirk though. Back in the previous life, I was always fascinated by the concept of magic, mostly because it gave power without physical exercise, or the need to rely on other people. So yes, I hope I'll get a quirk.

I remembered that I once heard that the younger you were, the easier it was to learn new things. During these last couple of months, this turned out to be true, as I managed to quickly pick up japanese, even though I always struggled with language learning. I toyed with the idea of learning a couple other languages, then realized how lazy I actually am.

It was determined that I was an odd child. I liked it, being special. It was like the best drug in the world, compliments. Especially when they were so easy to get.

I was quiet (when faced with other children), and quoting others "very smart" (since I did everything to appear like that when adults were around).

Loneliness was my only constant companion. It wasn't a new sensation, I was never much of a people person, but being treated as a baby was just the worst.

The parents, honestly they were kind of meh. I'm pretty sure I had some unconscious resentment towards them, which put a dent early in our relationship.

It didn't help that they were workaholics, but I guess you don't have much of a choice about that in Japan.

It was determined that I have a quirk. No one knew what it is however. The doctor said that it'll probably activate in the near future.

I was down in the park. It was close to my fifth birthday, and my quirk hasn't activated yet. Kids on the playground all had theirs, and those who didn't were labeled quirkless. The verbal bullying already began, but they were focusing on some other kid, sometimes throwing mean words at me. They didn't faze me, "I don't really care what other people's meaningless opinions are about me", that's what the logical part of my brain said. That's what I wanted it to say, and not like it was a lie, but, on some level, the words still hurt.

"We should show them who's the boss", was the thing that the emotional part of my brain said, not being helped by the fact that I was in the body of a four year old, and didn't have quite the grip on my emotions.

It was fine, for a while, I just sat on the swing, and I closed my eyes and enjoyed the wind as I moved. I certainly didn't expect to be rocked off by an explosion of all things.

I sat up from where I landed on the ground. There was a blond kid next to the swing, smirking, like he did a great deed. He looked very familiar, but at that moment my mind didn't continue that train of thought. No, it continued another one. One filled with rage.

I just sat there, I wasn't loud, I wasn't shouting back at the bullies (because he was one of them, I could see), and I didn't hurt anybody. And this little piece of shit just had to come here, and blow me off there, just to show it that he has that fancy little quirk. I can't stand these people.

And that was the part where I blacked out.

I woke up later, surprisingly, in the hospital. That was strange, to say the least. I wondered what happened. Maybe a spontaneous villain attack? That theory was quickly abandoned after I saw that I was alone in the room. And the window was locked. It wasn't normal glass, but some kind of stronger one. Okay, maybe it wasn't, but I like to think that I was judged an important enough patient to be put in a room specifically for violent quirks.

A man came in, wearing a doctor's uniform. He asked me if he should start with the good news or bad news. I told him to start with the good.

He told me that I unlocked my quirk. That filled me with joy, and contrary to what he expected, he second sentence did too. I was told that my quirk is very strong. I shapeshifted into some kind of black creature with a white mask, and attacked everything around me, starting with that blond boy. It was only pure luck that a hero was just right around there, or he would have died. I made sure to look shocked at this, but inside I was gleeful. Shapeshifting, I never expected something this great. He told me that my quirk is very dangerous, and I should never attempt to use it alone, since if I attacked someone they might die. I made sure to look scared, and I guess I managed it more or less, after that, they left me alone for a little while.

I immediately started brainstorming. My quirk activated when I was angry, so it's a safe bet to say it's tied to my emotions. This one will be convenient to use as an excuse, to show bullies their place. I wonder if I can control the shapeshifting more, and maybe stay more in control, not just black out and let animalistic insticts, guided by my emotions do the job.

The parents of my new body also visited me, told me that it's not that bad to get a "bad" quirk, and I can find a career in other paths. Everyone acted like my quirk is bad, like I'm the unluckiest person just because I got it.

The next day we did some tests. Before I transformed, my skin started cracking, like porcelaine. If I stopped before it shattered, I wouldn't activate my quirk. They didn't want to test that, so they just told me that whenever I feel angry, I should do breathing exercises, and not let my emotions control me. I nodded, and resolved to practice in private. One thing was clear however: I wanted to use this quirk, and for that I needed a hero-license. Another thought of mine was that it may also be beneficial to get close to the protagonist (looking back, I was a bit too ambitious, but looking back, it was also for the best), so their plot armor would extend to me as well. It looked like I was going to UA then.

AN: I hope I didn't make it too edgy, I just wanted to write a protagonist that isn't like most others.

If you want to imagine the creature he transformed into, then check out No Face from "Spirited Away", when he turned into a giant monster, that's what I had in my mind when I wrote it.

My knowledge about MHA is limited as well, so I'll probably make some mistakes in the future.

Edit: 2022. 02. 07: So, after several revisions, it didn't actually change much. It's still mostly a monologue that sets up the story, and doesn't do much else. There will be quite a lot of this, so if you already hated it in this chapter, then no point in continuining. If you think it's alright, from this point, it only becomes better, so, I hope you'll stick with it.
