Hinomaru Sumo

His goal is to become a professional sumo wrestler! Ushio Hinomaru goes to visit Ishigami High School, famous for its sumo program, but arrives at Odachi High School by mistake. There he meets Ozeki Shinya whose dojo has been overrun by delinquents.

Hinomaru is finally doing sumo in school! However, the club needs five members in order to participate in group tournaments. Ozeki and Hinomaru try to attract new members at club activity day where they meet Kunisaki Chihiro from the wrestling club.

Tsuji Kirihito has joined the club as a supervisor. The club's first step on the road to the national tournament is facing Eiga University High School in a practice match.

Kirihito orders the club members to harvest seaweed and do many other strange things, like standing on an unsteady boat to improve their balance. The club members admire Kirihito's methods, but have doubts about his experience and abilities.

The Dachi High sumo club will be practicing with Ishigami High School, a powerhouse which took second in the Kanto sumo tournament. The former middle school yokozuna, national treasure Mikazuki Munechika, Sada Mitsuki is enrolled there.

Hinomaru goes to practice at the Shibakiyama Stable, but he is so small they do not pay him much attention until he proves his prowess against a wrestler who had recently graduated. The relaxed atmosphere becomes tense as the practice intensifies.
