Naruto: the Six Paths of the Moon

It doesn't matter if a person from Earth travels back to Naruto, or if he has an artifact on him, it's not outrageous. The most outrageous thing is that the Naruto he traveled through is actually a universe; it would be outrageous if he had countless anime abilities. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
