In today manga we can see madara summoned gedo mazo ...buh I thought gezo mazo turn to the huge tree....pls who can explain,,,,,,and I can see it coming out of obito....pls anyone can explain this....I will greatly appreciate it.
The outside tree, shinju was a manifestation of the juubi. The real juubi was inside obito. That's why when shinju came out of obito, he was still jinchuriki because Juubi was still inside of him. When Naruto pull out the tailed beast chakra, the shinju manifestation stopped blooming and remained there while the juubi inside of obito transformed back into the gedo mazo.
