Big Naruto and his father, Minato Namikaze, had a long heart-to-heart.
Their conversation was much the same as in the original story. Minato Namikaze explained Naruto's origins and revealed the truth behind the Nine-Tails' attack on Konoha, as well as the Masked Man...
Big Naruto also explained where Little Naruto had come from.
Minato Namikaze was shocked to learn that Little Naruto had come from another Shinobi World.
But when he heard that his counterpart and Kushina were still alive in that other world, something stirred in his heart.
If only Kushina and I were still alive and could stay by Naruto's side...
As far as Minato Namikaze knew, his counterpart in the other world had never died in the first place. Resurrection never crossed his mind.
Genius though he was, Minato Namikaze was only a young ninja in his twenties. He knew little of the Shinobi World's secrets-even less than the Third Hokage...
Naturally, he had no idea that techniques capable of bringing people back to life existed in this world.
The only one he might have known about was Impure World Reincarnation, but that technique did not count as true resurrection...
After their conversation, father and son emerged from the other space.
When they returned to the Sealing Space, they saw Chang Wei beating Lai... sorry... wrong scene.
It should have been... fat Kurama thrashing skinny Kurama.
Meanwhile, Little Naruto sat off to the side, drinking Fat Nerd Happy Water and eating popcorn as he enjoyed the show.
Earlier...
After charging out of his cage, skinny Kurama had attacked fat Kurama, whose very appearance rubbed him the wrong way.
The reason?
Of course... the fat Nine-Tails looked plump and prosperous, with a glossy coat. He was clearly living a better life, and skinny Kurama was jealous.
