Keros

The God of Trickery and Being a Douchebag, but only to nasty dipshits who deserve it. Very big on reciprocity and karma.

He wears a foreign robe-like dress, the bow and quiver, and has nine vulpine tails on the body of a mostly-human man.

Owns the floofy kitsune as his personal servants and favoured race; all their souls are belong to him by default. Sell your soul to him to become one (unimplemented for long, long time) and get floofy tails of your own.
