Nekomaru Nidai

Nekomaru is a vigorous, boisterous, openhearted student who is passionate about supporting athletes, but suffers from dyspepsia. He frequently shouts when speaking, being a team manager. He is very optimistic and his willpower is immeasurable, but he isn't very smart and he's very bad at lying. He also really appears to enjoy fighting, often in the form of very serious training.
