Kappa

The Kappa is a Japanese water demon whose danger is tied to a particular vulnerability: it carries water in a hollow atop its head, and if tricked into bowing, loses the water and all its strength. Its entry combines a concise account of habitat and appearance with practical instructions for avoiding harm.

Identity and Habitat

The Kappa inhabits shallow ponds and rivers in Japan. It is often described as resembling a monkey, but with fish scales instead of fur. A hollow in the top of its head holds water, a defining feature that also explains how it may be overcome in a confrontation.

Behaviour and Avoidance

The Kappa feeds on human blood, but it may be persuaded not to harm someone if offered a cucumber carved with that person’s name. This advice presents avoidance as a matter of a specific, personal offering rather than force.

Weakness and Classification

If confrontation cannot be avoided, a wizard should trick the Kappa into bowing. The movement drains the water from the hollow on its head, depriving it of all strength. The account assigns it the Ministry of Magic classification XXXX, marking it as a creature for which the entry supplies both a warning and a concrete means of defence.
