demon's or fire people's real magic is not bound to just supernatural powers, it can also appear or effect different belief systems that shape them into whatever fits the narrative of jews, christians or muslims. they're shapeshifters, that's how they survive and remain at large.   idk if it's a fox or a cat but she's holding its tail too aggressively. this is supposed to be a playful scene but instead what you get is cruelty. if it's not demonic influence then why does that girl seems to enjoy the power she holds over something weaker than her?
