Osu Says No

I've been randomly doodling - There's one with Eko, but this is the one I've decided to post. Each time, I give the character(s) a certain colored background, then pretty much adjust their color scheme to that background.

Well, this is Osu. Ekon's first major demon he captured. Seems to have disinterest in a number of things, but if you can catch his attention, he's fun. Otherwise, when the other guardians are not around, he's there to protect the boy. Due to the violet background, I ended up letting his skin be as dark as when he's in his humanoid demon form~.
