Bleach: Fade to Black - Kimi no Na o Yobu

Synopsis:

One night, two mysterious figures infiltrate the Twelfth Squad’s laboratory for nefarious purposes, wiping out a third of Seireitei in the process. Amidst the commotion, the intruders approach Rukia and indirectly cause everyone she knows to forget about her – that is, except for Ichigo, who manages to escape this mind alteration. Sensing that something is wrong, Ichigo travels to Soul Society for answers; but with obliterated memories, everyone treats him as an enemy. Now, with all thirteen protection squads chasing him, can Ichigo find a way to retrieve the lost memories of his friends and rescue Rukia - not to mention find out why was she targeted in the first place?
