I've just got a single question that involves the skips you've been having. It might seem inconsequential but it's been bugging me a little bit.
You've been skipping things, going from the end of the Tsunade retrieval arc to the end of the snow arc... I just wanted to know why he doesn't receive a little experience between them. There was probably a month or so between the two, so he probably would of had sex at least once in that time.
Apart from that, this story is quite enjoyable and I'm looking forward to more.
