Kappa
Encyclopedia Entry:
An aquatic type monster that inhabits watery areas like marshes and rivers throughout the land of Zipangu. Its form is close to human, but it has green skin and carries a round, dish-like object on top of their head. They also have a shell, and webbed feet allowing it to swim effortlessly.
Most of them are mischievous and have a strong willed personality, but they aren't very violent. Kappa children often intermingle and play with human children. They especially like playing a game popular in Zipangu called "sumo" which involves pushing one's opponent out of a ring, or pushing one's opponent down. Compared to human girls their bodies are far more robust, and with their mighty strength they can even pin boys down.
But don’t let yourself be fooled, they are monsters and as far as they are concerned, the children they meet are just future marks. Through their socialization with human children, they unconsciously decide who they will have as their husband.
Even when they push boys down and pin them down during sumo, they experience a powerful arousal that they can't quite understand themselves. Once they grow a certain amount, their lust suddenly swells up tremendously. They will go into heat and assault the man they targeted during childhood in an attempt to force intercourse.
Additionally, while their body is wet, their vitality sky rockets, so they are extremely dangerous when found near the water’s edge in this period. If they sight their mark approaching the water’s edge, they will drag him in immediately and try to initiate sexual intercourse. One must be very cautious.
The dishes they carry on their heads are always wet with water. The dish is their weak point. If it dries up, not only will they lose strength, but she’ll also become extremely sensitive to stimulation. Touch the area, and she’ll no longer be able to move.
