I've been wondering if DMC's Yamato would work on Ichigo, like, separating his Quincy side from his Shinigami/Hollow side like Vergil separated his human side from his Demon side.
Do you guys have any plausible reason for this to work this way, or why it doesn't work?
Yamato could also in theory separate the connection between a Shinigami and his Zanpakuto? or a Quincy from the blood he ingested from Yhwach?
