When Kuze calls him over Kariya notices who he's talking with and tells him not to waste his time with people who couldn't win the District Preliminary. Kuze mentions he doesn't mean it and he was moved by Ushio's match. When Kariya is told to stop acting cool when they weren't picked to compete at their own District Preliminary. Panicking, he says his and Kuze's names will echo in the entire country.[1]

Backstage afterwards, Kariya claims his sumo isn't wrong and he will win next time. Agreeing with him, Kariya throws a lioncloth at him and asks if he will fight. Kuze confirms he will after a moments silence. Asked by Kariya if he's fighting for his revenge. Kuze declines and mentions he wants to fight in a formal match. When Kariya questions if his blood was stirred up by Ushio, Kuze confirms it. Shortly afterwards, Kuze now dressed for competetion heads to the sumo ring and prepares to face Kunisaki Chihiro.[8]

Facing Kunisaki, he enters a gorrila poistion with his hands on the ground. The matches begins with Kunisaki charging at Sōsuke from a distance, and then attempting to grapple him from behind, until Sōsuke turns around.[9] When Sōsuke goes to grab him Kunisaki moves to the edge of the ring. Approaching him to grab ahold of him, Kunisaki prepares an under arm throw until stopped. When Kunisaki slips behind him, Sōsuke gets his arm around his body. Kunisaki attempts go for a neck throw until Sōsuke grabs ahold of his lioncloth and charges out of the ring, winning the match.[10]

In his next match, he defeats his opponent via railroading.

Kuze charges towards Yūma headbutting in the chest which sends him the dege of the ring. When Gojou stops himself, he approaches Kuze and lauches a strike, much to his surprise. Pushed back by his attack, Yūma proceeds to grab him by the throat.[12] As Yūma launches a series of strikes Kuze pushes him back to the edge of the ring. When Yūma steps back to deliver another stirke, Kuze grabs his lioncloth and delivers an outside arm throw. Winning the match he leaves the ring and heads over towards Kariya Shun. As Kariya mentions he were able to advance without any problems.
