About Ichigo’s heritage. What if Aizen is actually the real father of Ichigo. Isshin is just a step-dad. Juha Bach is Ichigo’s other father, Aizen and Juha Bach being a gay couple. They needed a substitute woman to have a baby, and they chose Ichigo’s mother Masaki. She had the baby but fell in love with it and didn’t want to give it and ran away to the World of the living and found love, Isshin Kurosaki. Aizen and Juha Bach have been planning to get Ichigo, their “should be” son, back and after Aizen’s plan failed, Juha Bach is now trying to get Ichigo back and at the same time destroy SS and free his lover, Aizen.
