Ryūhō is a loyal warrior of the Fūma ninja clan, fighting alongside protagonist Kojirō and fellow members Ryōma, Kirikaze, and Shōryū. His primary allegiance lies with his clan and its leaders, driving his participation in clashes against rivals like the Yasha clan. Shaped by lifelong training in Fūma traditions, he stands as a dedicated combatant committed to the clan's cause.

During the initial Fūma-Yasha conflict, Ryūhō battles to defend Hakuō Academy against Seishikan High School and its Yasha allies. He confronts the Yasha Generals, fighting consistently as one unit within the collective Fūma force throughout this conflict.

The live-action adaptation introduces new dynamics for Ryūhō. Temporarily joining Hakuō Academy's judo club, he develops a competitive rivalry with Kurojishi, a Yasha General leading Seishikan's judo club. This subplot offers glimpses of normalcy and their adversarial interaction.

In the Sacred Sword War, Ryūhō continues his steadfast role, fighting with the Fūma clan as they ally with the Cosmo Warriors against the Chaos Warriors, maintaining his position as a supporting combatant.

The Fūma Rebellion arc sees Ryūhō actively opposing the New Fūma Clan insurgents under Shimon. Alongside Shōryū and Kirikaze, he works to crush the rebellion and safeguard the clan's legacy. He participates in key battles against traitors like Raien, Muma, and Raizō, his actions contributing to the group effort.

Across all media, Ryūhō remains a constant presence as a loyal Fūma warrior. His combat skills are noted, particularly his judo proficiency in the live-action version. He operates primarily as a steadfast ally within the ensemble.
