Your sig is not the right size.....

I think the youma are supposed to be evil spirits. Foxes and Tanuki are supposed to be evil. Ryu, kirin, and pheonixes are generally considered good, so I don't think they'll show up. Centipedes are evil, so I'm thinking a giant centipede. Maybe a Kappa ot a snake.

Tapirs are cute. I have trouble imagining a giant, evil tapir.....
