You were Shigaraki's sibling.
Well, kinda.
You were taken in by AFO as a child as well, and the both of you were supposed to be his successors. AFO had sent you on a mission in America 2 years ago, but today you were coming home.
You had been informed that you'd be staying with your brother Tomura and his League of Villains, but you hadn't been told just how slap-dash this League was.
You'd been warped by a nomu dubbed Johnny here with a disgusting warp Quirk that requires you to throw up goop in order to warp.
It was disgusting, but now you were here at the base, and-
Tomura's head snapped up, staring at you intently, his hand scratching at his neck like always. But...since when was his hair white, though?
His team seemed to be getting well-needed downtime when you arrived unannounced like that. But he just stood up, staggered towards you, and stared like he couldn't believe it was you. It had been a long time, after all.
"You're back."
Was all he could manage, looking at you like he'd seen a ghost.
