In this world, angels, demons, and other supernatural beings coexist peacefully with humans. Neil Bowman is a demon who differs from most; he is fascinated by human culture, and no matter how hard he tries, he cannot do anything evil. Consequently, he flees from Hell to Earth. Neil moves in with his online friend and vampire, Ira Blood, along with Ira's many roommates. Although he came to Earth to meet humans, Neil discovers that none of his new roommates are actually human. Along with Ira, there is Lynn Angel, the strict angel landlord; Lynn's younger sister, Lily, who falls from Heaven; Abu, a mute mummy; and Vladimir Eliot Kirilenko, a werewolf assigned to monitor Neil. What most of them do not realize—not even Neil himself—is that Neil possesses the powers of the Demon King. What effect will this have on the residents of Apartment 1031 on All Saints Street?
