The day of prophecy (June 30, Konoha Year 94).
Mahā Land. (Using the eye power of his Rinne Tenseigan, Sasuke had transported Earth and humanity into a dimension with an artificial sun. Then, using [Divine Technique: Omnipotence], he created a conceptual land in the spatial void Earth had left behind, a battlefield on which to face Shi Mei. Its terrain was constructed from the hardest minerals in the universe; even Golden Wheel Reincarnation Explosion could not cleave it all the way through.
This was "Mahā Land."
The two great God Ninja and the Ten Celestial Ninja had assembled.
There was no question who the two great God Ninja were.
Ōtsutsuki Sasuke and Ōtsutsuki Naruto.
After Sasuke had become an Ōtsutsuki all those years ago, Naruto had also abandoned his human identity and become an Ōtsutsuki.
However, the way Naruto became an Ōtsutsuki differed from Sasuke's and that of the many Celestial Ninja.
Sasuke and the Celestial Ninja had all followed what could be considered the old method: becoming Ōtsutsuki through the traditional process of thawing a Kāma. The difference was that the density of information their Kāma carried could be worlds apart.
Yet Naruto had become an Ōtsutsuki by following the path Orochimaru had originally prepared for Sasuke: undergoing an "awakening" after acquiring all the necessary Ōtsutsuki elements.
Back when Sasuke acquired his Tenseigan, he would have had to take the "awakening" route if he had not received Ryūshiki's Kāma.
It was worth mentioning that Naruto had acquired the Tenseigan he once lacked with the help of his wife, "Hina-ya."
Who... was Hina-ya?
Hinata Hyuga, who had thawed Kaguya Ōtsutsuki's power... Ahem, we would get to that later.
As an Ōtsutsuki, Naruto also followed a different path of advancement from Sasuke.
Let us first discuss how Sasuke had grown stronger
