I can sort of understand the theory behind White being Kaien, what with the similarities in hair and disposition, but he's not. From what I can recall, Kaien's body was absorbed by Aaroniero long before the White incident occurred, and the physical similarities come from Isshin being a Shiba (the personality just seems to run in the family).
