I wonder what those girls' abilities are that caused Yachiru to disappear out of her uniform. It reminded me of the failed Hollowification experiments.

At any rate, I assume if Yachiru went back to Isane after Kenpachi told her to then Isane, along with Kensei and Rose's bodies, are gone too even though we didn't see their uniforms. Just an assumption.
