It appears that they have changed some things, but I feel that’s only natural. For instance, it looks like the showdown between Ichigo and Renji and Byakuya will take place during the day. Also, there’s still nothing on Yuzu or Karin (Ichigo’s sisters), but they’re probably the easiest ones to remove from the equation if you can’t put everyone in.
I need a western release of this movie! Come on Warner Bros. Bleach will be in theaters in Japan on July 20, 2018.
