I think Rangiku will be the next to get bankai because Rangiku has been a lieutenant a lot longer than Rukia and she's got more capability to do so. But I do also want Rukia to get bankai as well. :)

i dont anyone is gonna show their bankai at the moment because the qunicies will steal their bankai

Just because Rangiku is a lieutenant, it doesn't mean dat she is gonna get a bankai a lot faster than Rukia,
she has a gud relationship with Sode no Shirayuki, rite?

Rukia trains more. Rangiku is lazy.

I think Shuuhei will learn Bankai next, then probably Rukia, since Rangiku is a bit of a slacker... Shuuhei must train a lot, because he is really good at using his Shikai and has probably been a Vice-Captain for quite a while too. XD

I so want Kubo to give her a bankai! that'd be awesome!!

Thanks for response u guys! Rukia is my favorite bleach character and hope she will be next to get bankai but i didn't forget about shuuhei, i wanted to do ladies first, maybe shuuhei could go up with Izuru Kira.
