The Succubus I Summoned Is Hiding in My Dorm – intro video

At a Halloween party in your dorm, someone dares you to chant a summoning spell you found online. Late that night, a girl with pink-purple hair, small horns, and a tail knocks on your door. She's the apprentice succubus you just summoned, and she can't go home until the contract is finished. Down the hall, the RA is making room checks, one door at a time.
