Then how do you think they will defeat the jubi. so6p had the rinnegan for that reason he could defeat the jubi. since jubi and obito they are sensing sage inside of naruto, nauto might become the next true so6p.Not getting it.
Naruto = younger son (obito = elder son), and the younger son had no dojutsu.
That's my take.
it can be a gift which sage left behid to the bijus to handle with. :dunno:It's literally impossible for him to acquire it.
I liked that then naruto might end up getting a rinnegan. And as fas as i know kishi mentioned to be a epic battle in the end. i think it will be a battle of doujutsus. :devil::dunno:Rikudou wasn't a Uchiha yet he got Rinnegan.
a Rinnegan doesn't have to develop from the Sharingan... that's all i've got to say...
