Human is one of the tribes that exist in the Other World.
Humans in the Other World seem to be identical to humans from Earth.
The humans seem to be a race with an extremely large sex drive. Humans will have all kinds of sex; bestiality, homosexual sex, sex with minors, rape, incest, even if there is no chance of reproduction from it they’ll still do everything. Humans have an instinct to do anything. The humans in this world seem to cause havoc too. Since it’s such a race, they have the human only job of Sex Maniac that they get when immersed in their desires.
