So in the recent chapters of Naruto we have seen how Kakashi is now capable of teleporting himself back and forth from the other dimension. As far as I remember, isn't that the basis of Tobi's Ghost mode technique? (or whatever you call it) Now I was wondering if he could master Tobi's "phasing through" technique as well, or he already has and he just doesn't realize it LOL. And please don't give me that "low chakra" reason..I don't think that applies anymore cause if it did, he would be dead already cause he spammed his Kamui more than enough to kill himself -_-
