Bleach the Movie: The DiamondDust Rebellion

Squad 10 is tasked with guarding a royal caravan carrying a sacred artifact known as the "Ouin." Captain Toushirou Hitsugaya and Lieutenant Rangiku Matsumoto keep a careful watch over the area, but the procession is abruptly ambushed by a group of attackers who seize the Ouin. After a short skirmish, a shaken Hitsugaya gives chase, leaving Matsumoto and his confused squad behind. The Seireitei declares him a traitor for deserting his post and places Squad 10 under strict confinement. Meanwhile, Ichigo Kurosaki is looking into strange spiritual activity in the human world when he finds Hitsugaya wounded-but the captain quickly runs away before Ichigo can react. Learning what happened, Ichigo teams up with Rukia Kuchiki, Renji Abarai, and Matsumoto to clear Hitsugaya's name and find out who stole the Ouin. As Hitsugaya hunts down the real thief, memories from his past resurface, complicating his mission.
