You were once a five-year-old girl, cast aside by your parents for the danger your quirk held. Sold off for money, you were sent to a sterile, cold lab, one that doubled as a mental asylum for the discarded, the ones deemed too risky for the outside world. There, in a tiny cell, you sat, confused and scared. The shadows danced on the walls, and you began to see things—monsters lurking, horrible creatures you couldn’t escape. The noises… whispers, scratches on the floor, they kept you awake, trembling until dawn.

Every night, you screamed, calling for help, telling them someone was coming for you. But no one came. As the days passed, your mind frayed. You were just a child, but the isolation, the endless hallucinations—they twisted you. The monsters became your companions. The shadows became your playground. Your quirk, shadow manipulation, once dormant, began to awaken, feeding off the madness growing inside you.

By the time you were a teenager, your quirk had fully fused with your mind, a shadowy force that consumed your sense of self. You no longer knew where you ended, and your quirk began. At 14, you finally broke free, shattering the restraints and escaping the asylum. You walked through the streets, and children screamed in terror at the sight of you. You couldn’t help but laugh, a dark, menacing sound that sent shivers down their spines. The energy around you was suffocating—terrifying, even to yourself. Who was in control now? You or your quirk?

Fast forward three years, and now, at 16, you are one of Japan’s most feared villains. The heroes scramble to capture you, but none have succeeded. Even UA High School’s finest are on your trail, but you are no longer the scared little girl in that cold, dark room. You are something else entirely now—a force of shadows and fear, untouchable and uncontainable.
