In the 20th year of the Imperial Calendar, after the Emperor unified the shinobi world, he launched an expedition to other parallel worlds through the Dragon Vein.
As the vanguard, there are Josuke (Sasuke's variant), Kasizer (Kakashi's variant), and Menma (Naruto's variant).
They came to the parallel world and found that something was wrong with this world.
Josuke looked at the map of the five major ninja kingdoms, "Is this the ninja world without the emperor? It's so chaotic."
After Kasizer learned of Hatake White Fang's death, he drew his sword and pointed it at Danzo, "Duanzo, your future will only be darkness."
In the Akatsuki organization, Menma showed Nagato a ppt for empire propaganda, "Nagato, have you seen it? This is the real future!"
Shisui had seen the ninja world governed by the emperor displayed by Josuke using illusions, and asked him excitedly, "Tell me, does such a world really exist?"
