User blog comment:TheBody84/Ichigos father being the former Kenpachi/@comment-1659217-20091025181110

@Minato88 What .wicket was refering to is when Ryuken asks Isshin if he has his powers back and calls him Kurosaki. That is when Isshin remarks that it is the first time Ryuken calls him that. As far as I can read there is no mention of Isshin being banished. Urahara calls him Isshin-san and asks "how it feel to take the form of a Shinigami that you abandoned 20 years ago" Later in the same conversation it is clear that while Isshin knows about the excistance of Vizards he knows nothing else, but that someone looked for their base of operations and tried to uncover their goals. Isshin also tells the hollow that captain level control the size of their zankutou - And damn near makes it clear that he is at that level himself. Isshin knows about the Hougyoku and Kon thinks "...he´s so strong! it´s crazy! is he really Ichigo´s stupit dad"
