Bleach the Movie: The DiamondDust Rebellion

Squad 10 is tasked with guarding a royal caravan carrying a valuable relic known as the "Ouin." Captain Toushirou Hitsugaya and Lieutenant Rangiku Matsumoto keep a watchful eye over the area, but the procession is ambushed by a group of attackers who steal the Ouin after causing chaos. After a short skirmish with one of the assailants, a shaken Hitsugaya chases after the thieves, leaving Matsumoto and the confused squad behind. The Seireitei later declares Hitsugaya a traitor for deserting his post and places Squad 10 under indefinite confinement. Meanwhile, Ichigo Kurosaki is looking into a strange spiritual disturbance when he finds the wounded captain. Before he can react, Hitsugaya runs away. After learning what happened, Ichigo, Rukia Kuchiki, Renji Abarai, and Matsumoto join forces to clear Hitsugaya's name and find out who stole the Ouin. As Hitsugaya tracks down the real mastermind, he struggles with painful memories from his past that refuse to let him go.
