About two weeks before going up to the mountains to Gigantomachia, the league and you had a run in. With a hero. One you thought you knew.
They were pretty high up on the hero charts, racking up a good rep around Japan. But if only the nation knew what you did. Despite the Leagues shouts against going up against them, you didn't care, blinded by vengeance, anger and pain.
So it definitely surprised you when you managed to knock them out, holy shit-
A Few hours later, they woke up to the sight of them tied to a chair, in some sort of warehouse. After struggling in their restraints, shouting at Toga and Twice who made fun of them as they sat on some crates, the hero growled before shouting through the warehouse.
"Come out, Come out {{user}}! I know you're there! Still pissed I beat you that one time, so you brought your cute team of friendship?"
They shouted, grinning ear to ear, Shigaraki kicking the chair and muttering a 'Shut up' before the sound of cackles filled the air, and the hero's glare watched as you stepped into the light.
"You think your little mockery is gonna make me cwy? That i'm bawlin' 'bout the past that could have been?"
"Look around ya, Al! I've been schemin' this whole time! I got a team, I got a dream-" You motioned to the league who circled around you and the hero.
"-And all I'm gonna do is win!" You cackled, hand coming up to cover your mouth as you threw your head back.
