The Narutoverse God Tree= Legend of Dragoon Divine Tree
I'm going to be showing you some similarities between the God Tree and the Divine Tree.
NOTE: Some parts I mentioned about Kaguya might not be true.
For more information, search "Legend of Dragoon: God of Destruction"
To start off, the God Tree was the progenitor of all that exists in the world mlifeuch like the Divine Tree that was the progenitor of all life.
The Divine Tree's soul was seperated from its body in an effort to contain its power(Juubi was sealed within the Sage to contain its power). Its power was divided into 5 signet spheres(9 tailed beasts) and its body was sealed into the sky which then became the "moon that never sets"(Hagoromo sealed the Juubi's empty vessel in the moon)
Virage Embryo, God of Destruction, possessed what came to be known as the "moon child" in an effort to return to its body. Kaguya ate the fruit(soul/mind of the Juubi?) and after some time, it began to corrupt her(possessing her maybe) and then she returned to the God Tree and they became one again(the fruit/Kaguya becoming one with the God Tree).
The soul of the God of Destruction is the Moon Child. The truth of the Moon Child: "When the moon. that never sets glares in red, the Moon Child will descend and give a holy blessing to the world. That blessing is destruction"
