Gouma is a large strong teenager with an extremely athletic build, he is called the strongest in the school. Carol (a kouhai) called him 'Gorilla-senpai' to his face.
Gouma was the secret weapon of the opposing volleyball team in the tournament, he faced off against Tomo and Jun's team in the third round. After knocking Jun out he started provoking and taunting Tomo who got really angry, Tomo later scored and won the tournament.
Sometime after the tournament, Tomo and Carol spotted Gouma they both call out to him, although Carol still calls him "Gorilla-senpai", her reasoning being that "Gorilla-senpai" is a cute name. Gouma watches on as Tomo got Carol into a headlock to force her to apologise, Gouma seems pretty embarrassed being given a cute-sounding name. It was later revealed that he has a girlfriend of his age but with a short stature who calls him "Take-chan". Jun was quite surprised at the height difference between the two and even called into question the legality of their relationship, Gouma assured him that he was innocent.
