Nidai is a vigorous, openhearted student who is passionate about supporting athletes but suffers from dyspepsia (AKA indigestion.) He shouts a lot but for his own reasons. He is close to Akane Owari and trains with her a lot.

As a coach, he trained a lot of good players including figure skaters that can perform 6 revolutions per spin and tennis players that were able to turn an almost-win into a win with a total of 36 hours of playing time.
