"You and your siblings are Lunatics. Why the hell did I want you?" Tsukiko Yonaga's mother yelled at her older brother Asahi.
"Fuck you, Mom. You're a drunk bitch that can't even take car of her children! If we didn't go to dad's every other weekend we'd be dead!" Asahi shot back, louder still than his mother.

Tsukiko had a very powerful quirk, but she never wanted to be a hero. Not until the day a group of notorious villains declared on national television that they would be killing off all quirkless individuals, one by one. Asahi's quirkless twin brother, Nichirin, was seventeen. Tsukiko had no choice but to use a place in Class 1A at UA as an excuse to hone her quirk's power, to avenge Asahi and protect Nichirin from his fate.
Being socially ackward, mute, and depressed as fuck wouldn't have stopped her brothers from doing what they believed was right, so why should it stop her?
