Otsutsuki! Otsutsuki DNA is what's required to gain a doujutsu.. Uzumaki/Senju/Uchiha/Hyuuga, It's all the same an only two have the means of making a doujtsu because of bloodline..
Which means my statement earlier stands, that It's Otsutsuki linege that awaken doujutsu not regular human clans..
What is this eye if not from on1 of the only doujutsu user on earth descendants?..
No it isn't, Hagoromo said so himself that the dojutsu genes went to Indra, the body genes went to Ashura. Of course there are exceptions but if they were the dojutsu would either be Sharingan, Rinnegan or variants of those. But based on the design in that scan the dojutsu comes from neither of those two powers.
You could say the dojutsu came from Hyuga blood being mixed with Ashura blood but again I thought that was the whole point of Kishi introduced Tenseigan before the Hyuga arc.
I like to believe it's possible for a Senju/Uzumaki to be born with Rinnegan, that's what I was really hoping when we first saw Nagato, but that isn't the case in this arc.
This new dojutsu makes no sense based on the design and only hints at an excuse for the author to come up with a new dojutsu the plot line does NOT need. Author should just stick to what Kishi gave us and work around that, there's plenty of untapped material in that already.
