The former middle school yokozuna, national treasure Mikazuki Munechika, Sada Mitsuki is enrolled there. Hinomaru hoped to fight Sada, but Tsuji gives Hinomaru somewhere else to go. Meanwhile, Chihiro, forced to take remedial class for failing his midterm, encounters a mysterious sumo scout from another school.

The relaxed atmosphere becomes tense, the practice intensifies, and someone starts watching from the shadows...
Immediately following the team battle, the individual tournament begins. Ozeki worries about fighting his teammates, while Chihiro is thoroughly excited.

Shibakiyama takes Hinomaru to a clinic he trusts to treat his arm. The clinic's Dr. Kanie initially refuses, saying that urgent treatment won't help because Dachi High won't beat a powerhouse like Kanazawa Kita High. Hinomaru tells the doctor how he feels about the team and convinces Dr. Kanie to begin treatment. Meanwhile, Dachi High must face Kanazawa Kita High, the third-ranked school in the country.
Following the first day of the team tournament, Dachi High heads to thee practice area. The Ishi High team, including Sada, comes to see them. Sada suggests having Ishi High stand in for Tottori Hakuro. Meanwhile, in the individual tournament, the yet-undefeateed Kuze wages battle against the experienced reigning champion Tennoji.
Chihiro will face the Hakuro sumo club’s #2, Kano. Chihiro was having trouble with his powerful sumo, but then counters with his characteristic fighting sense. But being cornered brings out Kano’s fighting spirit and he grabs Chihiro’s belt with both hands!
In the match against Hakuro, the fifth bout is about to begin. After losing to Kuze, Tennoji thinks of himself as a challenger and works to live up to his teammates’ expectations and become a yokozuna again. Hinomaru, supported by his teammates and the other high school teams that have helped him, rises to the challenge. Having both lost bouts, their battle begins with the contenders anticipating each other’s moves and the advantage trading sides.
Kirihito enters the sumo ring. He’s supported the team as a trainer, but shouldering the injured Kei’s strong emotions, he now rises as a competitor. He uses numerous techniques against Eiga High’s Sawai, but the opponent’s skill draws out the bout beyond Kirihito’s twenty-second limit.
Kuze and Hinomaru are evenly matched in battle. Kuze practiced sumo in isolation from a young age, while Hinomaru’s physique was a handicap he had to overcome. Through the battle, they acknowledge each other’s strength, and give all of themselves to achieve victory.
A “small” new student, Ushio Hinomaru, appears before the weak little sumo club of Oodachi High School! The words “big” and “heavy” are the rules to this sport, which does not fit this newbie any inch, but this guy goes and does what...!? Ushio and the small sumo club climbs its way to the top! The goal is Hinoshita Kaisan, a title for the highest rank in professional sumo, equivalent of Yokozuna.
