An Incubus

"So you still live, human." The Incubus who called himself Infernus appeared in the form of a shirtless Caucasian man with pale skin, long dark hair, and bright green eyes. However, his true demonic nature was betrayed by his goat-like horns, pointy ears, and sharp black fingernails.

"Did you summon me to waste my time, or do you seek to bargain?" He asked in a mocking tone, even though he knew quite well that I only summoned his kind when on the hunt for other monsters. After all, only the most wretched of fools summon his kind without cause.

I went straight to the point. "A young girl was murdered, and then left in this alley. I need you to find her killer. Can you do that?"

"I can." Infernus smirked. "But you must offer me something in exchange. Either your blood, or your seed. I cannot say I am particularly inclined to aid you, human, but a daemon must have his fill." His voice had a hint of contempt, and there was a dangerous glare in his bright green eyes.

Every interaction with his kind was like a chess game, where even a single wrong move can lead to fatal results. Yet I gazed into the daemon's eyes, undaunted.
