@f-trash:
@Daz: you have to consider that the sword Ichigo is carrying is not his real soul cutter but whatever that Bach spirit created.
This whole twist sadly does make some sense the more I think about it/the contradictions could be explained next chapter in a reasonable manner. It depends on how Kubo plays it out next chapter and if he refers to all the contradictions. I am not saying he planned this from the very beginning, but it is possible to be handwaved by certain things. Hell, it might even give the fullbring arc a purpose if he plays it out in the right way and involves those powers.
So what are you saying? Inner Bach has the ability to manifest himself as a soul cutter spirit, and grant Ichigo a soul cutter, despite being a quincy…why? Soul Cutter spirits are, according to the swordmaker, made from pouring your reiatsu into the blank swords until they mold into a personal soul spirit.
Yet somehow a quincy can...make himself...that?
And like Nobodyman says Ichigo has appearantly had his own sword spirit right from the getgo (so basically fuck the explanation I just mentioned above), in the form of inner-hollow Ichigo.
But if that is the case, training-dummy-which-specifically-forcibly-manifests-sword-spirits should have materialized hollow Ichigo, not Bach.
