Carrera is a female demon whose job is to create a wish granting contract with a human being in exchange for their soul. Along with her partners/rivals Mercedes and Rati, they carry out this job for the benefit of the demon world. When Carrera is summoned by the nerdy Ogawa, she finds him to be more interesting than her previous clients and develops a crush. Mercedes tries to get involved with Ogawa also to compete with Carrera. However, the female angels are upset by this disturbance and are willing to purify the demons with their precious “holy water” to save Ogawa’s soul.
Carrera, Rati and Mercedes are three succubae demons who will grant any wish in exchange for a soul. Ogawa uses a summoning spell to gain vengeance, but when he sees the sexy Carrera, he gets a better idea for a wish. An army of beautiful angels look on, waiting for an opportunity to descend on the demons. They have a plan to send Carrera and the others to heaven, after a bath in their sacred "holy water."
