In the cartoon "Slam Dunk", coach Anxi picked up the ball out of bounds and handed it to Mitsui, saying, "The game is not over yet. Don't give up so soon. " Mitsui said to coach Anxi twice, "Coach, I want to play basketball, I want to play basketball." Because Mitsui remembered that he didn't give up in the final, he went to the stadium to watch the basketball game with crutches after being injured.
