Kintan is an upperclassman at Dairin Temple who trains alongside the protagonist. Introduced as a fellow disciple, he forges a close friendship with Chinmi shortly after the young fighter's arrival. Their dynamic anchors a central trio within the temple's rigorous training environment.

Kintan actively engages in martial arts practice and periodically mentors Chinmi. During one documented training session, he instructs Chinmi on maintaining balance against overwhelming forces like ocean waves, particularly when grounded on unstable or confined surfaces.

His character expands upon his original manga role. Though featured in the source material, the anime adaptation elevates him significantly into the central group dynamic, establishing him as a prominent supporting figure throughout the series.
