Bleach Movie 3: Fade to Black - Kimi no Na wo Yobu

A mysterious pair attacks Rukia Kuchiki inside Seireitei and steals her memories. The effects spread far beyond Rukia herself: the Soul Reapers forget that she ever existed, and even Ichigo briefly loses his memories of the person who first gave him Soul Reaper powers.

With Kon's help, Ichigo remembers and returns to Soul Society in search of Rukia, only to discover that his former allies no longer recognize him. Forced to fight people who once stood beside him, he follows the traces of Rukia's forgotten past toward the two attackers who took her away. The closer he gets, the clearer it becomes that restoring her memories may mean confronting a bond Rukia herself buried long ago.
