Kappa

Kappa are a reclusive race, hiding away up in the mountains, although this is a fairly silly thing to do, since the majority of them have Humans as their main food source. They can survive without food, of course, and some have become purely reliant on cucumbers to sustain themselves, but there are still the Kappa that like the taste of blood, and they go down to the closest village every now and then and kidnap a Human, or if they accidentally kidnap a Crystal Demon, they're returned the next day. Those that have turned 'Vegetarian' are usually less brutish than their meat eating counterparts, and for some reason they have a major interest in technology. The Kappa are extremely imaginative, and they have been rumored to have created Technology that is far superior to our own, and happens to be eco-friendly too. Not many people see Kappa, but when they do they usually run, or in a humorous turn of events, the Kappa itself flees due to their shyness. They always wear something on their head, whether it be a hat, or a beanie, it must keep the pool of water on top of their head there at all times, or they will be forced to serve the next person they see. They can also manipulate Water and condensation.
