Seiryoh Tryouts Arc
Jinbo was the coach in charge of the Seiryoh tryouts and was the second-to-final say in who made the team or not. He originally wanted to immediately kick out Akira Honda and Katta Oosawa, but was convinced to let them stay and give them another chance. After the two boys impressed Kaidou, he agreed to offer them a spot on the team, but they rejected it in favor of another school.

Kanto Preliminaries Arc
During the Kanto Meet Preliminaries, Seiryoh played against the team from Johnan Public High School. Jinbo attended the match with his team and observed their game, but was not very involved. He was angry when they lost but soon accepted the loss and moved on.

Takeomi Kaidou
Kaidou was the final say in who made the Seiryoh team or not, suggesting that the coach trusts him to lead the team and allows him to take control. Jinbo is very proud of coaching Kaidou and having him on his team, and they appear to respect each other highly.
