Teppei Kiyoshi is the cornerstone upon which Seirin High's basketball club was built. Known across the court as 'Iron Heart' and counted among the elite Uncrowned Kings, he overcame a grueling rehabilitation journey from a serious knee injury to reclaim his place on the team in his second year. Combining a center's raw physical dominance with a point guard's sharp passing vision, Kiyoshi dedicates himself entirely to shielding his teammates — earning his reputation as Seirin's unbreakable defensive pillar.
