Synopsis

Zeo, a poor necromancer, receives a request for an exorcism and visits a certain mansion. As he prepares to start his work, the client, a woman named Luca, seems to be plotting something. In reality, she is a vampire who lured Zeo in with a fake request to drink his blood. Thus begins a chaotic and over-the-top gothic romance between the two. (Source: Natalie, translated)
