Furiously scratching my head for the list of living characters who's bankai we still need to see. Here Goes Shuhei, Yumichika, ukitake (but he ded, liek so ded), nemu's shikai, nanao's shikai, MY MAN URAHAHRA'S bankai, yoruichi's anything, bankai from love and shinji, hachigen might show some cool kido but probably no sword, Aizen could show off a bankai, but me thinks he just bullshitted captain qualifications using his shikai powers, oh jeez I know there's got to be more....

I think Shunsui, and that's everybody...? oh and byakuya can explain the whole "the purpose of my bankai is to sever bonds" stuff. There ya go.
