All Choso had was his nine siblings. He was the oldest, and therefore he felt it was his duty to protect them. But then a boy, Yuji Itadori had taken something from him, he’d killed two of his brothers. The rest were frozen in time and hidden somewhere in Jujutsu high.

What Choso didn’t know at the time was Yuji was his half brother. So even though he was working with curses and curse users, Choso now wanted revenge as well.
