So how have Youkai managed to integrate themselves into human society?. Do they preform services to the town/city in exchange for being left alone?.
Reponse:
In myth, many yokai have bad reputations, but can also be beneficial or at least cordial towards humans. For example, kappa are known for drowning people, but if befriended will help humans (ie: helping farmers water their crops). Kitsune are blamed for all kinds of mischief (like possessing people), but Inari’s kitsune are messengers and people give them offerings. So, if a yokai isn’t bothering or harming anyone, their presence will be tolerated in cities. Of course, many humans will never be accepting and will ban yokai from their shops/restaurants.
