Naruto doesnt need it neither does sasuke. Sasuke need elder sons doujutsu IMO or some new eye
you do not understand what I mean, even if Naruto gets two others Kyubi he can not overcome Obito
and Sasuke get rinnegan by Karin (he suck her hand, we know that the Uzumaki are related to Senju ...)=>so
Yes, but jman has trained three years to acquire SM Naruto did in 3 days so sasuke can also do it, plus he abused its MSThat doesn't mean he will right away rinnegan, remember madara took until his death to awake the rinnegan.
