The southern island chain of Okinawa is home to a number of unique yokai which are not found anywhere else in Japan. One of these is the kijimunā: an elfin creature which makes it home in the banyan trees which grow all over the Ryukyu archipelago. Physically, kijimunā are about the same height as a child, with wild and thick bright red hair, and skin tinted red as well. They wear skirts made of grass, and move about by hopping rather than walking. Kijimunā retain the appearance of child-like youthfulness into their adulthood. Males are noted for their large and prominent testicles.

Kijimunā lifestyle mimics that of humans in many ways. They fish along the shores, live in family units, get married, and raise children in much the same way as the native islanders do. On rare occasions they even have been known to marry into human families. The kijimunā diet consists entirely of seafood. They are excellent fishers, and are particular skilled at diving, which they regularly do to catch a favorite dish: fish heads (specifically double-lined fusilier fish heads). They are especially fond of fish eyes (even preferring the left eye over the right). Okinawans attribute eyeless corpses of fish found on the beach to picky kijimunā.

Kijimunā have a number of peculiar fears and prejudices. They despise chickens and cooking pots. They are extremely put off by people passing gas. However, the thing they hate most, above all else, is the octopus. They avoid octopuses at all costs, despising them and fearing them at the same time.

Kijimunā often help fishermen catch fish, or aid humans in other ways in return for a cooked meal. When they form friendships with humans, they can last for a lifetime; such will often return to their human friends many times, even spending holidays with their adopted family.

Kijimunā attacks on humans are very rare. Cutting down the banyan tree in which a one lives is a sure way to earn its wrath. Kijimunā thus wronged have been known to murder livestock, sabotage boats so they sink while their owners are far out at sea, or magically trap people in hollow trees from which they cannot escape. Sometimes they press down on peoples’ chests while they sleep, or snuff out lights during the night. The enmity of a kijimunā, once earned, can never be satisfied for as long as it lives.
