What if Yachiru was really Kenpachi's zanpakutou? Or maybe, she's really a part of Kenpachi's zanpakutou, including Senpo? Please, enlighten me, guys. :)

In chapter 527, Unohana mentions that Zaraki's "partner" had just awakened together with him; referring to his Zanpakuto. Nozarashi then adresses Zaraki and realizes that he can finally hear its voice. It then introduces itself to him.

Now, Zaraki and Yachiru have been friends for a long time, so if she was really his Zanpakuto spirit, then that introduction makes no sense to me. I admit it's strange how Yachiru seemingly vanished into thin air, leaving her Shihakusho and lieutenant badge behind, but from there it's quite a stretch to assume that she's a Zanpakuto spirit.
