Has anyone considered it's not actually Kenpachi. Since, Guremi's power is based around imagination, and who is the one person that Yachuri would imagine coming to save her?

It's possible that his power works both ways, in that it's the imagination of both that becomes reality. Improbable yes, but possible. It would explain why he was talking about Yachiru's thought processes when he was turning her into a cookie. In that it bases off of her imagination, and as she is childish, she would be more inclined to think of Kenny coming to the rescue.
