If there is anything we can take away from this interview its that the entire series was essentially an asspull, as Kishi himself said he didn't know what he was doing half the time, and when he did have an idea was usually superseded by the editor. Which in many cases WAS a good thing, otherwise we'd have an inukusou hokage.
