also being that naruto is a reincarnation of ashura and sasuke is the reincarnation of indra
is anyone else curious of the other half of the chakra of the 10 tails tree beast
because it clearly states that both hagoromo and his brother sealed the beast inside the both of them and i think its safe to say in a time like that, he had children of his own who wouldve adopted powers of the sages and most likely the 10 tail beast
so im kinda thinkin SO6P brother actually might get his own arc (VILLAIN)
