The Japanese word that translates as not-person. In Rokugan, a hinin is someone who practices a questionable trade that benefits nobody but themself- charlatans, criminals (including pickpockets and bandits), entertainers (the most notable of whom are the geisha, and some actors/musicians), professional gamblers, and the eta, the corpse-handlers. When they could be caught, the ninja were treated as hinin- but the ninja do not exist, right? At least in Rokugan, they don't.

While a samurai may need a good reason to slay a heimin farmer, killing a hinin is not a crime because they are not protected by the celestial order- however, there can be repercussions for slaying a powerful daimyo's favorite geisha that could well be fatal.
