User blog comment:TheBody84/Ichigos father being the former Kenpachi/@comment-1624279-20091025000519

The whole 11th squad not using or being good with Kido is something that came about after Kenpachi became captain. Squad 11 formerly knew & used Kido before that. Example, Maki Ichinose knew & was very good with Kido(& yes I know he was an anime only chracter). If & i'm saying if Isshin was a captain the only squad he could have been captain of was 10(cause of the timeline). This in & of itself is doubtful, cause Rangiku would have known him, yet she has never commented on Ichigos surname. Plus we saw a glimpse of the former Kenpachi & he was a little to small & scraggly to be Isshin.
