Synopsis
Squad 10 is deployed to the human world to protect a royal convoy carrying the powerful "Ouin" relic. Captain Toushirou Hitsugaya and Lieutenant Rangiku Matsumoto stay watchful. A group of attackers suddenly strikes the convoy, steals the Ouin, and creates chaos. After a brief fight with one assailant, a troubled Hitsugaya chases after the fleeing thieves, leaving Matsumoto and the rest of the squad shocked. Following this, the Seireitei accuses Hitsugaya of abandoning his post and places Squad 10 under an indefinite lockdown. In the human world, Ichigo Kurosaki investigates a spiritual disturbance and encounters the injured Hitsugaya, only to be surprised when the captain suddenly runs off. After learning what happened, Ichigo, along with Rukia Kuchiki, Renji Abarai, and Matsumoto, sets out to clear Hitsugaya's name and uncover the truth behind the Ouin's theft. Meanwhile, a figure from Hitsugaya's past lingers in his mind as he pursues the real culprit.
