Ok guys, I realize this is probably a stupid topic to start but here goes. Now I get that we all just love our doujutsu and all the crazy powers they grant us, but I'm experiencing a sort of dilemma here in light of some of the newer in formation as revealed by the So6P in the manga. Originally we just kind of figured that the Rinnegan was just some rarely occurring doujutsu because of Nagato just having it. Then we eventually came to know that Madara ended up giving Nagato the Rinnegan without him knowing about it (probably through some genjutsu mind-wipe or something) after he mixed Hashirama's DNA with his own. Which lead us to believe that Mokuton + Sharingan = Rinnegan. After which in an attempt to lower how many people could utilize the Rinnegan on SL people started requiring maxed Mokuton and Sharingan resets along with Rinnegan resets as well to make it legit. Now what always seemed off was the fact that Danzo had multiple Sharingan, one of which being Shisui's Mangekyou Sharingan eye, and Hashirama's DNA BUT for some reason he never awakened the Rinnegan in ANY of those Sharingan eyes. Now thanks to the last couple chapters it's become relatively clear that the Rinnegan is actually more or less attained by mixing the chakra of Ashura & Indra.
For those of you who aren't familiar, those two were the sons of the So6Ps. And their powers were so great that after they died they're chakra kept getting passed down to particular individuals through the generations. Hashirama & Madara was one such rivalry where Ashura & Indra's chakras were in play, thus meaning that when Madara implanted Hashirama's DNA inside himself he had successfully mixed both chakra signatures to allow the Sharingan to awaken into the famous Rinnegan. Which is why Danzo was unable to do so, seeing as none of his Sharingans nor his own chakra signature has the necessary essence of Indra to mix with Ashura's, which he possessed through Hashirama DNA.
So here in lies my question. If Mokuton & Sharingan isn't required for the Rinnegan anymore, then how is this gonna work out on SL? Does the criteria change to needing the proper resets along with possessing the chakra of Ashura or Indra respectively (and thus being something of their incarnation) AND mixing the chakra of your friend/rival to then lay claim to this legendary KG? And if so, then exactly how many reincarnations of Ashura & Indra are going to be running around SL? Cause if we go by reincarnation as both we and the series know it, then there will only be 1 pair of individuals each generation to act as incarnations of Ashura & Indra. And a new pair will only show up after the last pair inevitably dies. So what are your thoughts?
