OK this should have stayed dead according to the Bleach Wiki:Discussion Policy. I'm going to close it by those rules.

But alas, In Chapter 540 Nimaiya did state that White entered Ichigo's body. However he also said that it melded with Ichigo's latent Shinigami powers and the result created his Zanpakuto and thus spirit. We know this because Nimaiya didn't state White was his Zanpakuto but the Hollow standing behind ichigo was was Zangetsu. The other Zangetsu confirmed in Chapter 541 that his Zanpakuto IS still called Zangetsu, not white. The result of his own powers being melded with a being created by Aizen from many Shinigami and their own powers. However, it is never confirmed if the entirety of White went into Ichigo or a part of him. He could still have been part of Masaki as well after she gave birth, we do not know that, but we do know that he has the ability to spread like spores or a virus because only part of him needed to enter Masaki in the first place because she destroyed the rest of him. But alas this is going in circles. And it was a dead topic per rules above. Have a nice day all.
