On Earth. All chakra, Doujutsu and other shit came from the Juubi on Earth.Hmm if it true all chakra and dojutsu comes from the juubi, how come Kaguya pre Juubi fruit has Byakugan?
How did all the Ootsutsuki have KKG along with chakra if they received no chakra or no connection from the Juubi fruit? If I am not mistaken their clan KKG are the byakugan like the hyuga.
Kaguya traveled to earth without eating any fruit, so her chakra must be high.
This has nothing to do with the fact that she was choosen as host because of her special chakra.As for Kushina she shown awesome feat without being a Jinchuuriki, although as a Jin she has 0 feat.
