now that Itachi has taught sasuke izanami the only person i can think of sasuke using izanami against is tobi because tobi will try to use Izanagi to aviod defeat n izanami will be the perfect counter . so does that mean there is a chance of us seeing naruto n sasuke teaming up to face tobi or sasuke taking out tobi to be the final villain. cos i dont see why itachi would fully explain how it works if its not going to be used again . thoughts?
