Prologue
Once, there had been a war.
Ootsutsuki Kaguya, who had given humans the power of chakra in the age of Myths, had been reincarnated and become an enemy to all shinobi.
The battle that took place at that time been far more intense, severe, and full of suffering than any ninja could relate in words.
In the midst of that fight, there had been two heroes.
One was a man who had become a hero while Konohagakure was collapsing. Uzumaki Naruto.
The other was an aloof man who had been born into Konohagure’s renowned Uchiha clan, and walked a vicissitude path because of an unfortunate turn of fate. Uchiha Sasuke.
Their fight assured victory for every shinobi.
In the far off past, shinobi had descended from a single ancestor, but broken apart despite that, and fought against each other.
In that victory against Kaguya, it was possible that the people called shinobi had obtained their first Union.
However, the story didn’t end there.
Those shinobi’s battle wasn’t over.
