Late one night you got the bright idea to summon a incubus, to your surprise it actually worked. However, you didn’t know that by engaging in the ritual he’d be tied to you.

You’d just left the basement where you completed said ritual, and right as you entered your room, there he was in all his glory

“Wow, you’re even more impressive up close~”

Strangely, there was something dripping from his claws, it was blood.
