Sorry… I’m a failure as a coach… I didn’t want anybody to say that we ambushed them either. So, lets show them all by our actions rather than words

—Koga, to Kitasumi High


Koga (古賀) is the head coach of Kitasumi High basketball team. His last name has not been revealed in the series. Everyone on the team calls him ‘Koga-ji’ or ‘Old Man’ by Tarou.

Appearance

Koga is about 169 cm. He has medium length grey hair with some wrinkles on his forehead. He wears circular stainless steel glasses and his eyes are usually closed. Koga’s age has not been revealed, he looks to be in his mid to late 70s.

Role as Coach

Koga is the oldest among all coaches in this series. He has been Kitasumi High’s instructor for a while. He is a strategist who can instantly determine player’s habits and weakness. However, due to his age he can make some wrong judgements. As in the beginning of the practice match against Kuzuryu High, Koga underestimated Sora’s team, as he instructed his players not to wear their club’s uniform. Believing that Kuzu-High were not taking this game seriously as they wore their team’s practice jerseys. When Kenji and Sora scored couple of points for their team, Koga apologized to his players and instructed them to change back into their official uniforms as this game will be played by their team’s full strength.

He is very kind and also gives advice to players of other teams. When Kitasumi High won their practice match, Koga approached Kurumatani and gave him some guidance. He informed Sora, if he had kept his cool and drawn a foul during the last play or passed the ball to Kenji, Kuzuryu High would have won the match.      

Previously, Koga had thought of retiring as the team’s instructor. Ever since Taro got enrolled in Kitasumi High, their club has gained some recognition. Koga believes that Taro is the one who can help their team to qualify for the Inter-High tournament. At the Kanto Tournament (winter), Koga upon meeting Tomohisa (Kuzu-High’s coach) informed him that he will retire when Taro’s last Inter-High chance ends.

  • It’s true that it was a bad shot… But the failure was before that. You hesitated whether to shoot or pass right?

  • And that’s where your biggest mistake was… The moment you got the ball you weren’t looking at the goal.
