Naruto: After Unifying the Ninja World, I Invaded Parallel Ninja Worlds

Hashirama: "I'll distribute the Tailed Beasts to you." After Hashirama bowed his head and begged for mercy, the ninja world barely achieved a brief period of peace, but hidden beneath that peace was an even deeper turmoil.

Uchiha Senju: "I'll distribute the Tailed Beast Bombs to you."

Having transmigrated from the 21st century, he deeply understood that true peace could only be achieved through unification. Possessing the bloodlines of both clans, his Susanoo-clad Great Buddha quickly unified the ninja world. To ensure that the arrival of the Otsutsuki clan would not bring disaster upon himself and this world, he issued an order. The entire nation spent ten years developing spatial cross-dimensional ninjutsu.

As the cross-dimensional expedition began, the people of the ninja world finally realized they had misunderstood their Chairman too deeply.

Kakashi: "Having absolute power, yet still needing to go on missions and be a dog for the powerful, unable to maintain peace? Are ninjas not people, just tools? Was the White Fang of Konoha criticized to the point of suicide just for saving his comrades?"

Obito: "What?! My Uchiha clan was wiped out? Good, good, I'd like to see which audacious beast dared to do that!"

Nagato: "You can only become Hokage if everyone acknowledges you? Poor Naruto was CPU'd from a young age!"

As parallel worlds were conquered one by one, the world channels opened wide, and countless people broke down and wept.

Sasuke: "Itachi Uchiha, I'm so jealous! The me in this world actually has a warm family and a beloved brother!"

Naruto: "Turns out I'm not a dead last, I'm Uzumaki Naruto, one of the Empire's Twin Stars!"

Six Paths Naruto: "Chairman, please send me to Konoha in year 67. Pervy Sage, this time... it's my turn to save you!"

When the Otsutsuki clan finally arrived, they were dumbfounded.

"Hey, you old bastard, there are Super Six Paths everywhere, is this still our home country?!"
