An early, failed Vaizard experiment by Aizen is left to die in the Dangai. However, at the instance before the Kōtotsu would have ended his existence. A space storm pulled him out of the dangai and into a new world. Once he enters this new world he will have to adapt to the powers that be and figure out a way to get home. I do not own the Bleach Series or the Saint Seiya series they are properties of their respectful authors Tite Kubo and Masami Kurumada.
