Betrayal Eye

A demon monster with one big eye. It feeds on the life force of its prey, often appearing out of nowhere. It is said that those who hear the laughing voice of a betrayal eye will lose their luck. As such, many who encounter sudden misfortune or a loss of health are looked upon as being possessed by this demon. The demon avoids well-lit areas, and instead, appears suddenly in darker areas, such as during the night or underground.
