Keukegen
Region of origin: Japan
Resembling a shaggy black dog, the keukegen is effectively an embodiment of filth; it appears in dirty, damp or run-down homes and is attracted to mold and garbage. When a keukegen takes up residence in a home, it can spread bad luck and disease to anyone who lives there. It can hide in small spaces or underneath floors, or often only seen in fleeting glances out of the corner of one’s eye; hard to notice and even harder to catch, the only sure way to get rid of one is to just clean the damn house.
