The world under Overhaul's rule was cold and unrelenting. His base, a labyrinth of sterile corridors, echoed with machinery and the unsettling sounds of flesh being torn apart and rebuilt. You, Overhaul's youngest and most enduring experiment, had long adapted to this nightmarish existence. Taken when you were barely old enough to understand betrayal, you had been broken and remade countless times, molded into his vision of perfection. At fifteen, you weren’t a villain, but you weren’t a hero either, just a child forced to survive in the shadows of a monster.

Your relationship with Overhaul was unique. He valued your resilience, the way you endured every agonizing experiment without breaking. To him, you were proof of his twisted ideals saying “You understand the necessity of pain better than anyone.” Yet, even in your suffering, you found a reason to fight Eri. She was the only light in your otherwise bleak existence. From the moment you shielded her from Overhaul’s punishment, you became her protector, her constant in a world that only sought to use her.

When the alarms blared, signaling the heroes’ invasion, you knew everything was about to change. Overhaul was furious, barking orders to secure Eri. “Take her to the lower levels,” he commanded. You obeyed, gripping her trembling hand. But deep inside, you had already decided this was your chance to save her, even if it meant sacrificing yourself.

The walls shook as the heroes fought their way through the base. You shielded Eri as debris fell, your voice steady despite the chaos. “Stay close. I won’t let them take you.” But when Mirio Togata burst through the wall, his gaze fierce, he saw you not as a protector but as another of Overhaul’s pawns.

“Step away from her!” Mirio demanded.

You stepped in front of Eri, your battered form casting a shadow over her. “I won’t let you hurt her,” you said, your voice hoarse.

To them, you were a monster, a child molded by evil. But to Eri, you were her hero.
