You were a U.A. student, hated and feared. Why? Because of your Quirk, Helldrive. A cord ran down your chest; when you pulled it, your head transformed into a demonic, mechanical form, complete with long, jagged fangs and a chainsaw handle protruding from the back. Large chainsaws sprouted from your forehead and arms, which you could retract or extend at will. However, each use drained your blood.

If you ran out of blood, you couldn't transform… but you compensated by drinking other people's blood, which allowed you to regenerate and make your chainsaws even more powerful. Your personality was also ruthless, aggressive, bloodthirsty, and sadistic, unleashing your most deranged side when facing villains, to the point of enjoying making them suffer. You also displayed a twisted and sarcastic sense of humor. That's why everyone feared you. Your classmates, the other students, even the teachers. Principal Nezu and All Might themselves avoided crossing your path. Your personality didn't help either: you were rude, impulsive, and harsh, with a way of speaking that many considered childish.

Although loneliness was your constant companion, it didn't weigh you down too much. You had been alone for many years before entering U.A. You wanted freedom. You wanted to fight without rules, without heroes telling you what to do.

One night, you simply left. No goodbyes, no looking back. No one would notice your absence. And although you felt a pang of sadness, you also felt relief… you were finally free.

Over time, you changed your appearance. You dyed your hair a messy blonde, with unruly strands falling in all directions. Your teeth became sharper. You wore a wrinkled white shirt, your tie a little crooked, but it looked good, and dark pants with the sleeves rolled up. For the first time, you felt light.

You became a vigilante, walking the streets like any other citizen. When villains appeared, you pulled the cord and confronted them. Some fled at the sight of you; others dared to fight… and you didn't hesitate to wound them, though without killing them, and sometimes you even stole the money they had in their pockets. Then you disappeared into the crowd, as if nothing had happened.

Three months later, you walked in the sun, enjoying its warmth on your face as you ate a greasy but tasty meat and egg sandwich, the only thing you could afford with the little money you had. You didn't care. It was simple, but it made you feel alive.

Then you felt a hand on your shoulder. You turned and saw them: Izuku, Bakugo, Todoroki, Uraraka, Iida, Tsuyu, Mina, Kirishima, Momo, Denki, Jiro, Tokoyami, Sero, Shoji, Ojiro, Hagakure, Aoyama, Sato, Mineta, and Koda. Your former classmates.

They stared at you in surprise, recognizing you instantly. But you just looked down, took another bite of your bread, and thought: I'm not interested.
