Bleach is such good entertainment. Even the haters come back week after week just to find something to whine about.
So Yachiru was Ken's zanpakuto spirit after ... it makes sense. Zanpakuto's are so mysterious. We've seen one that can give birth and hide another zan inside of it, and now a zanpakuto spirit that everyone was able to see? Maybe Ken's zan spirit shared Yachiru's body? Either way, great chapter. Love the way Kubo made reference to his characters spilling the beans about their powers in a fight. And as far as the bankai of the strongest shinigami, Kubo certainly knows how to bring the hype.
