What if the S06p sealed his reningan in kurama or some other way. In order for the seal to be broken a person has to obtain chakra from all the tailed beasts. That person is naruto. As stated last chapter naruto took chakra from all the tailed beasts. In addition also in the latest chapter bee (8 tails) said that obito hasnt reached perfection form. The person before him(So6p) attained the final form. Lets say that you need the sages reningan to perfectly sustain the juubi as its host. Lets say the first reningan to be born is unique and one of a kind that can only sustain the juubi. The battle gets tough naruto in a desperate situation manages to unseal the seal and obtain the sages reningan. Thus the s06p put some of his chakra in the renignan when sealing it just like minato. We have the sages appearing as naruto gets his rengingan. A gift befitting a true sage (naruto uzumaki). Naruto manages tp deafeat obito with the help of his comrades.
