You were a student at U.A., but hated by everyone. The reason? No one knew. From day one, none of your classmates, the other students, or the teachers liked you. Even Principal Nezu and All Might seemed to look down on you. Every day was the same routine: hateful glances, disgusted gestures, comments behind your back, practical jokes that left you humiliated, and blows that, more than once, made you spit blood. It was an endless cycle, and each time it became more intense, more painful, more unbearable.
Little by little, this began to change your way of thinking. Your opinion of heroes, of justice, of what it truly meant to be a hero, transformed. What was the point of being a hero if the villains never received a definitive punishment? What was the point of risking everything only for those same villains to be locked up and then released, returning to cause more chaos? You realized that people didn't care about ugly things, that people were capable of ignoring the grotesque acts of those who claimed to protect them. And if no one cared about you at U.A., if your existence was invisible to them, then everything you did would have no weight. No one would raise their voice, because you were already doomed from the start.
It was in that void that your new ideology was born. A different kind of justice, a vision that others couldn't accept: to show the world what a hero should truly be like, even if it meant getting your hands dirty.
The day arrived. Shigaraki was destroying the city, killing civilians with that sadistic, self-satisfied smile. All the heroes mobilized: the Big Three, Class 1-B, Class 1-A, the professional heroes. The mission was clear: stop him at all costs. But before anyone could react, you threw yourself at him without a second thought.
The battle began with a ferocity no one expected. You, U.A.'s most hated student, against Japan's most hated villain. Punches, explosions, chaos, destruction. The heroes evacuated the civilians while you tore at each other in a fight that seemed endless. For over an hour, you traded blows with Shigaraki until you finally brought him down. You were both covered in wounds, breathing heavily, but the difference was clear: he was lying on the ground, weakened.
Anyone would have expected it to end there. But not you. You took a metal bar in your hands and pointed it at his stomach. Shigaraki, chuckling in pain, looked up and muttered:
Shigaraki: "Heh... Are you really going to do it? Heroes like you don't kill... you don't have the guts. You're just a kid playing at being a vigilante."
His voice was a whisper, a challenge, a final mockery.
You stared at him, gripping the bar so tightly your hands bled. With cold calm, you replied:
You: "I'm not like them. I don't care about their false justice. I do what they never dare to do... eradicate the root of evil once and for all."
And then you did it. Without hesitation, you drove the bar through his stomach, ending his life.
The cameras captured everything. The citizens, the pro heroes, the two U.A. classes, the Big Three... they all saw it. Their gazes were filled with horror, thinking you'd lost your mind, that this wasn't being a hero. But you didn't care. Because that, that act, was your true self. That was what it meant to be a true hero: to do what others didn't dare to do. To show everyone what justice should be.
