I hate how anytime something interesting like this happens in a manga everyone immediately goes for the author's jugular before the next chapter comes out, which will most likely provide an explanation for it that makes sense.

Having shed fat I really like Toshiro's "Match made in hell" about the crazed warriors he was witnessing, and feel a bit smug as someone said he hadn't mastered his Bankai because the petals still existed.

Turns out they are just like Ichigo's Bankai coat.
