Bleach Movie 4: Jigoku-hen

Masked Sinners escape from Hell and attack Karakura Town, revealing a realm reserved for souls whose crimes were too grave for ordinary reincarnation. Their leader Shuren targets Ichigo Kurosaki's family and abducts Yuzu, forcing Ichigo to enter the forbidden world below.

Guided by a Sinner named Kokutou, Ichigo descends with Rukia, Renji, and Uryuu through layers patrolled by the monstrous Kushanada. Hell amplifies the power Ichigo fears most within himself, and the rescue soon exposes a deeper scheme that could break the chains imprisoning the damned and threaten the balance of every world.
