I actually didn't know a chapter had released until I saw this post, so thanks for that.

Anyway, this predicament Ichigo and Renji are in seems somewhat reminiscent of Ichigo's Bankai training, where he had to find the right blade to win. I'm assuming a similar goal is present here, where they need to prove that they care for their respective Zanpakuto or something along those lines. I guess we'll see.

Also, that comment on the women being Zanpakutos has me wondering if they're all spirits and Kubo just made the Unknown Tales arc possible, or if they were born in a Human form like Senna. Either way, the process that created them might play a vital role in the reforging of Ichigo and Renji's Bankai.
