Madara (Kishis Words) says it is Rinnengan ..... is he lying ? Then he also lied about Naruto Power , or what?
Manga says they both get the half Power of Hagoromo , and that means the Eye from Sasuke is actually the Power from Hagoromo. And not Sasuke's Power or what you thinking
Hagormo says that Kaguya was to storong (with this Eye that she has ) and then he says that nobody should have so much Power.
And then he should after all, give the same Power to Sasuke ( who constantly changing his opinion of the World etc.)
It's just disabled.
Stop dreaming please , maybe Hagoromo could switch from Rinnengan with Tome , to Rinnengan without Tome.
I believe, i am talking here to a stupid wall
