Considering that the bad guys seem to have all the godlike powers in this series, I welcome, even embrace such an unexpected plot twist.

Obviously Kubo wouldn't have kept Nanao's Zanpakuto a mystery for so long if it wasn't something unique/powerful, and useful for situations like this. Seriously, what did you expect? That it could shoot fire or ice. Wow, so unique! :P
