I don't want to be toxic or anything but I honestly cant see why he should stay on the leaf, is it to take over the village? if so he may as well just remake Uzushiogakure and find the member that are spread across the ninja world, I honestly think it would be time much better wasted that do d rank missions with a emo and a pink lollipop, one would kill you just to get stronger and the other would kill herself to please the emo, plus what can the leaf give him? he already has 2 perverted lovers keeping a eye on him in some time a perverted snake will also join the club, well i will just keep reading .
why is he staying here? this is basically just canon but being really op.like become a mercenary, join or kill the Akatsuki. revive Uzushiogakure, get the zero tails, kill ororchimaru and danzo , make your own team of people like haku and kimimaro. so many things he could be doing and he is wasting his time watching sakura and sasuke do basic chakra control.
Now that I saw it, I think the only thing Kakashi ever teach the team is tree climbing exercise right? Naruto shadow clone, rasengan, bijuu cloak, etc all learn from other source... Sakura medical and theory all learn from other source too... The only one that really learn from Kakashi is Sasuke and even that is one rush training montage..
