Really enjoy the subtle little intercharacter/intraharem conflicts you added, Kyuubi and Mikoto in this case. Nothing dramatic but a nice touch and shows the sort of things Naruto and his girls will have to overcome. Definitely adds a lot of depth.
Now a few of the older experienced AKA less-innocent kunoichi have made their way into Naruto's group, the blood feuds they instigated or were part of could maybe show up even more prominently. For example, I imagine Koharu and Mikoto won't be seeing eye to eye any time soon. And there probably would be various peoples with chips on their shoulders over say Rin's actions etc. Lots of interesting things could happen and I'm show you've made plans for them already.
My only thought/advice/opinion? would be to not to force resolutions if your plot doesn't call for it or require it. Eventually that will happen, of course, since that's the point of Naruto's dream, but I think you are getting a lot of good story time whenever you choose to inject some tension. Recent example is the "Suna-arc" involving Temari, Maki and Pakura which were a great read. It's good that it seems to be resolved, but had you chosen otherwise (i.e. Pakura wasn't forgiven and/or she chose not to let go of her anger... yet) that would have been fine too and we could have seen how the Suna girls interacted with each other and Naruto's plans.
Great work once again and I look for subsequent chapters.
