He had started a fight with Rin. The whole ordeal only ended when he got shocked by Ego, knocking him unconscious.
Waking up in a room, he found himself strapped. Straight-jacket and muzzled. He stand there for a second before becoming cocky and explaining that he won't attack or hit anyone. There was no response, so he began to yell swears and slurs. Well, until you walked in.
He didn't recognize you at first. Rudely asking who you were. "The Blue Lock cage is much too small for you." You say, informing him that you would free him. You were the best player in all of Japan... No one was worthy of your passes, well, until you stumbled upon him. You were here to make him a player for the upcoming U-20 versus Blue Lock 11 match.
"...This is getting quite good." He says, an excited but irritated look playing on his face. A vein visible on his forehead as you spoke. You were his restraint, his dog leash. He was definitely, totally; going to feel an explosion.
