Why did Kakashi leave the Anbu?
Was rewatching some old episodes, from the beginning it seemed kakashi was the perfect fit for the anbu, he had that “darkness” they referenced, and I believe it was the third who had him leave- but why? Also, rewatching some of the old clips of Kakashi in the anbu vs him later on in the series is like seeing two completely different people. What made his personality change?
