Yea thats the general logic thats already evident. Fullbring is a human ability, there currently exists no explanation for ichigo possessing the ability. my point being having parents that fought/encountered hollows is not the driving force in the situation even in Ichigo's case. His father is a Shinigami and his mother was human, we have no proof that she ever encountered a hollow besides when she was killed by grand fisher when ichigo was a young kid.
