Hinomaru Sumo

His goal is to become a professional sumo wrestler and yokozuna! Ushio Hinomaru is on his way to visit Ishigami High School, famous for it's sumo program, but arrives at Odachi High School by mistake. There he meets Ozeki Shinya, who trains diligently at sumo, but whose dojo has been overrun by delinquents. Angry that they would defile the hallowed practice area, Hinomaru confronts the leader Gojo Yuma and challenges him to a duel.

Hinomaru is finally doing sumo in school! However, they need five members in order to participate in group tournaments. Ozeki and Hinomaru try to attract new members at club activity day. But Hinomaru's chankonabe stew which he planned to use to generate instrest tastes terrible and the plan fails spectacularly! But one other student thinks the stew tastes delicious! The student is Kunisaki Chihiro from the wrestling club, and he and Hinomaru hit it off well, since they are both in fighting sports.

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. The club members don't fully trust Kirihito, but they still go to Eiga High. There, Hinomaru encounters his former rival, National Treasure Kusunagi Sword, Kuze Sosuke.
