Naruto: I merged with the consciousness of the Naruto world.

Sora,who had just completed the challenge of surviving in the ninja world for five years and earning a billion, unfortunately became the master of a polluted world before he could return. If he fails to destroy the polluted monsters, he will die.
Thus, a reincarnation game suddenly appeared in the ninja world. You can hunt polluted monsters and gain rewards that can bring you back to reality. You can exchange limited ninjutsu inherited from bloodlines and even items from other worlds.
Not only from the ninja world, but also from the World Government, Pirates, Seireitei, Demon Slayer Corps...
