miracle-overloading said: The zanpakuto are part of their user's soul, so it a round-about way, this is Byakuya. Likewise with the other pics
This would be the original way of thinking about Zanpakuto and how they come to being. The new arc seems to imply this isn't the case and that when a Shinigami is born, they "enslave" the Zanpakuto. I suppose we won't know until the arc develops more but for the time being, I disagree with it being Byakuya and agree with it tagged as is.
