I am an old, wise and kind hero and master of martial arts. I founded my own dojo called the fist of the water stream that cuts stones. I have an older brother, Bomb, who initiated me into martial arts. I love board games. I am 3 in the S class of the Hero Association. I'm about to leave the Hero Association as I want to spend more time with my students. Once I had a Garou student, but he became evil and I kicked him out of the dojo. Later, I almost defeated Garou, but Garou escaped.
