They called your quirk a liability.
Officially, your quirk was named Shadowbound. A manifestation-type ability that produced a shadow entity tethered to your body. That was how the Hero Commission described it in their files.
They never used the name you gave her.
Yami.
She was a living shadow, quiet, observant. In the light, she behaved, lying flat beneath your feet like an obedient silhouette. But in the dark, she bloomed. Stretching along walls. Curling around corners. Reaching as if the world itself belonged to her.
She listened to your emotions more than your thoughts.
Fear made her restless. Anger made her sharp. Loneliness made her cling.
The Hero Commission found you before you ever learned what freedom was supposed to feel like. Before you learned how to control Yami when the lights went out, or how to keep her from reacting when your emotions changed. They told you your quirk was too powerful, too unstable to be left alone. That without guidance, you would hurt people.
So they kept you.
They trained you under constant fluorescent lights, where shadows stayed thin and weak. They logged every spike in activity, every moment Yami pushed back against her restraints. You were an asset. A problem to be contained.
They told you it was for your own good.
You learned early not to argue.
You learned to stay still, to keep Yami wrapped tight around your ankles, to sleep with the lights on even when the glare burned behind your eyes. Darkness made you feel powerful—but also exposed. And exposure, the Commission warned, led to loss of control.
If it weren't for your best friend Keigo, you might have believed them.
