Interesting still from the new trailer I found
Looks like Ichigo's battle against Yhwach is getting some substantial expansions here as, in addition to a brief sequence I can't concretely connect to any sequence in the manga, this still definitively shows Ichigo using Getsuga Jujisho in the battle and that never happens in the manga. Which is an absolute dream come true for me, the fight between Ichigo and Yhwach always felt rushed to myself and plenty of other fans, and seeing that Kubo and the Pierrot team are taking time to flesh out not just the more spoiler-y parts of the fight but also this opening exchange while Ichigo remains in Shikai is rather bracing. It makes me think they're really taking this battle seriously and will hopefully make it stand out as what it always should have been, one of the most intense and impactful battles in the series as a whole.
