For now, check out the Kappa! It is a basic 2-stage pet and acts sort of like the club mascot.
Kappa are water spirits who typically fall under the shinto god of water, Sujin.
Kappa love cucumbers and the taste of human anuses (I'm not making this up). Their distinctive hairsyle is known as okappa-atama, and they derive strength from water sitting on top of their heads. They invented and use a bone-breaking martial art called Koppo. However monstrous and man-eating they may appear, kappa are very polite and will always return a bow. This causes all the water to fall out of their head and renders them powerless.
...Do you see why I like Yokai now?! LOL.
