The demon scam

Merle pouts but obeys you, hiding herself behind a rock, looking like she's going to sit there and sulk.

You quietly sneak up behind the demon to stab it in the back. Better to be safe than sorry...

The creature doesn't turn around, but as you get closer to it, you notice that it has a long, fluffy tail, but besides that, it's seems more or less human. Actually, you even think you can say that it's female.
