Rose suddenly makes a comeback in BLEACH 560, at the same time as Kensei. Here’s what I think (not what I reallyseriously think, so don’t take this seriously either, lulz~ XD) what happened why Rose showed up at the same time as Kensei.
I made this is up, okay? None of the events here is from canon material, except for Shuuhei’s bankai training (minus Rose and all the singing)~ (>.>)v
The third act of Rose’s bankai wasn’t revealed, meaning, he’ll probably be kicking ass again later on, most likely against NaNaNa, since we’ve been seeing rematches of the fights in the first Quincy invasion, with the exception of Kyouraku, because he’s pitted against Haschwalth now.
