Bleach Movie 2: The DiamondDust Rebellion - Mou Hitotsu no Hyourinmaru

While Squad 10 escorts the King's Seal through the human world, a mysterious group attacks the procession and steals the powerful artifact. Captain Toushirou Hitsugaya recognizes one of the attackers and abandons his post to pursue him, causing Soul Society to brand Hitsugaya a traitor.

Ichigo later finds the injured captain and becomes involved in clearing his name. The thief is tied to Soujirou Kusaka, a forgotten figure from Hitsugaya's past whose grudge centers on Hyourinmaru itself. As the King's Seal amplifies Kusaka's revenge, Hitsugaya must confront the history he buried before it destroys Soul Society.
