BLEACH: The DiamondDust Rebellion - Mou Hitotsu no Hyourinmaru

Amid a heavily guarded transport through the Soul Society, a treasured artifact known as the King's Seal (Ouin) is seized by a mysterious band of assailants. Toshiro Hitsugaya, captain of the Gotei 13's 10th Division and entrusted with escorting the relic, engages the raid's leader in battle—then vanishes without a trace. In the aftermath, the Seireitei brands Hitsugaya a traitor and issues a decree for his capture and execution. Refusing to accept the verdict, Ichigo Kurosaki joins forces with Rangiku Matsumoto, Rukia Kuchiki, and Renji Abarai, vowing to unmask the true mastermind behind the stolen seal, track down the missing captain, and restore his tarnished name. Now a fugitive moving through the shadows, Hitsugaya pursues the perpetrators on his own—and his search draws him toward a dark secret tied to a shinigami long dead.
