Muma no Machi Cornelica

Aru resides in Cornelica, a town inhabited by succubi. He is protected by a succubus named Lily, who shields him from others of her kind that seek to drain him. While assisting the local church, he is administered a drug by its head, Hakura, who informs him that recovery requires him to climax. Later, at a tavern, an accident occurs. The owner, Rosary, and the handyman, Arune, feign caring for him, but instead assault him without mercy during their extraction.
