Hijiri Himuro, once a celebrated Prism Star, launched his career at Edel Rose Academy, cultivating fierce rivalries with Rei Kurokawa, an unconventional street dancer, and Jin Norizuki, heir to the academy’s legacy. His skill and drive propelled him to prominence in Prism Shows, though his dynamic with Jin simmered with jealousy and hostility. A turning point arrived during the Prism King Cup when Rei’s disqualification for an illegal maneuver disrupted Hijiri’s rhythm, and a critical misstep in his Prism Jump handed Jin victory.

His fate shifted during a private ice-skating performance for June Amou, whose dance mirrored his late mother’s artistry. Jin’s orchestrated sabotage—damaging the rink—crippled Hijiri’s leg, forcing his retirement. While Jin ascended, Hijiri withdrew, grappling with June’s subsequent memory loss and their fractured bond.

Assuming leadership after Jin’s ousting, Hijiri revitalized Edel Rose as supervisor, prioritizing unity and perseverance amid financial strain and declining enrollment. He recruited Shin Ichijo, a prodigious talent, and guided Over the Rainbow through crises like debt and rivalry with institutions like Schwarz Rose. Drawing from his past, he mentored students to value passion and authenticity, inspiring Shin to adopt "Over the Sunshine!" as an anthem of resilience.

Hijiri countered Jin’s schemes—media smear campaigns and Schwarz Rose’s predatory tactics—with strategic vigilance, shielding his protégés’ careers. His expanded role in later conflicts underscored his advocacy for solidarity against industry pressures. Subtle details, like sharing a birthday with Jin and his name’s duality ("holy, sacred" juxtaposed with "ice room"), echoed his blend of quiet intensity and compassion. His legacy persisted as a mentor balancing ambition, rivalry, and redemption, anchoring narratives of perseverance in the Prism Show world.
