I don't see how Ichigo's mom could possibly be a Hollow. Unless she became one after dying, and if that's the case, Ichigo couldn't have inherited anything from her then.


Hollow Ichigo comes from one of two places.

1. From when Uruhara dumped him in the hole and Ichigo didn't get out till the last second and almost became a Hollow.

2. When Rukia gave Ichigo her powers, the black orb vaizard maker thing inside her leaked.
