She's cute. Not a big fan of the one fang tooth that is pretty common amongst the "feisty" drawings of girls, but it's a love/hate relationship.

The bandages must mean she's some sort of worker, tied together so they don't bounce around. However, her nails contradict this, and plus, from what it looks like, she's on a bed with a box of tissues in the background. So maybe it's a couple? Or, maybe the oni took ahold of the guy's gal,and now she's this demon thing wanting sex?
