The demon scam

You take a firm grip of your sister, pulling her to a stop. "What do you think you're doing!?" you scold, slightly out of breath, and hurting badly from your wound.

Merle keeps struggling half-heartedly, trying to get away, but you are able to hold her.

Suddenly, there are footsteps from behind, and you turn to see a female cat-demon approaching you, licking blood off her claws. She must be the one who jumped into the battle and fought off the hyenas...

You meet her gaze, feeling sick from the the pain in your wound. The cat demon gives a little smirk. "Hey there, cutie," she says. "Having fun, are you?"

Off course, she thinks that you are a demon, and a wound like this is like a scratch to them.
