I read your latest chapter and I would like to point out that sasugay cannot possibly have enough chakra to train with kagebushins because according to manga not even the sannins and the sandaime hokage were able to use the method simply because they could not maintain the jutsu long enough and the bushins would either dispel forcefully in under an hour of formation and also they were not able to make enough bushin to make a difference so the point is of ex-anbu like kakashi are not able to train with the kagebushin method it would be impossible for sasugay to even try it but never the less nice story and really like the zanpakto please continue writing and updating :). #P.S.-if you want you can refer the manga about the time when kakashi explains the truth about kagebushin to naruto before pawning off naruto to tenzo when naruto begans to start learning about wind chakra
