My friends displayed interest in playing a Naruto-inspired campaign. I was in the unique position of being able to fulfill that dream, and so this is the result! Feel free to play it or make it your own. All artists and artworks used in this document are credited in the appendix.
[Spoilers for the anime/manga]
Canon Naruto leaves a lot unexplained in the world building, like the nature of the existence of other intelligent species, and goes full on aliens. I went with a more fantasy approach and made non-humans Spiritfolk, and added a few more races as well.
