User blog comment:Soulreaper1234/So trying to Recap ShinigamIchigoHollow Who created him Urahara, Aizen or Isshin (and Masaki)?/@comment-452405-20100630233429

Umm if your asking how Ichigo was born and who did it, it wasn't Aizen or Urahara it was his parents. Aizen just claims to of known about Ichigo since birth.

If ya asking who created Hollow Ichigo, the answer is he was created in the Shattered Shaft when Ichigo regained his Shinigami powers.

If what your asking is neither of those things, then I'm lost.
