so it turns out that the sharingan and the rinnegan are demon bloodline from the jyubi as u can see from it's eye and they r decendants of the rikudo sage who was it's host, but doe's that meen that shodaime hokage's is a demonic bloodline as well because he was a decendant of the rikudo sage. got me wodering where all the other bloodlines came from.
Your theory is wrong because the rinnegan never came from the Juubi. Back to the drawing boards.
I think gazz is trying to say that the Rinnegan came from Gedo Statue or possibly from Juybi's combined Sharingan-ish eye.
Either way, that doesn't make much sense.
The theory already failed with the first line.
