There is a legend in the main timeline.
If a planet meets certain requirements, it will be chosen by the will of the universe and sent into a planetary arena filled with both danger and opportunity. There, it must seek resources to advance its planet and compete for one of the ten spots that will earn it promotion.
On the Ninja Continent, planetary consciousness suddenly awakens, and the sky screen turns into a massive live broadcast. Several people who meet the Six Paths-level requirements are selected: Uchiha Madara, Uchiha Obito, Uzumaki Naruto, Uchiha Sasuke, and Otsutsuki Toneri.
The five of them can also choose two people above the Super Kage level who are connected to them by blood or marriage to join them...
They have become the people who will decide their planet's fate, and are about to represent it in battle.
Either they use the arena's resources to help their planet advance and become officially recognized, or they fail and expose their planet's coordinates, becoming a prize everyone in the universe wants to claim.
A certain spiky-haired guy: Tsk, I got revived again. Who's responsible this time?
A certain white-haired sorcerer: Huh? Something like that exists? I'm the strongest! Leave it to me!
An extra: Huh? Why me? I can't do this!!
A certain bald guy: Are there more strong opponents to fight? I'm already trembling with excitement!
Little skit:
With no one to team up with, Madara from a parallel world is forced by the will of the planet to lend a hand. Looking at the familiar mask in front of him and a woman with the beauty of a goddess whom he doesn't recognize at all, he says, "Tsk..."
Obito: ...
He decides to take out his anger on the old man from the parallel timeline!
A Li: ...
Madara at this point in time should be really fun to tease!!
The two of them grin mischievously...
Madara, watching the big screen in the parallel world: ...
Theme: For the planet! Give it your all!
