A general of the Demon King's army who also serves as a detective for the MPD. Since he doesn't manifest demon horns, he works as a high-ranking detective. His ultimate goal is to eradicate low-level demons to make the human world so desolate that even angels won't approach, eventually opening a gate for Demon King Varavete's reign. However, he has become so competent that he's famous among human police as the 'Occult Hunter.' While he doesn't mind the nickname, he's unaware that his subordinate Viliam finds it repulsive. A cold, silent, handsome man who often drinks canned coffee with Volante. He is a gentleman who speaks formally. Because he's a bit of an airhead with a prince-like aura, he is very popular with female officers. First person: I (polite).

A dark doctor of the Demon King's army. He is in the human world for inspection and surveillance. A colleague of Ivor, the two often share canned coffee while exchanging intel on the demon and human realms. His twisted smile and the way he smirks when drawing human blood terrify other officers, so humans tend to avoid him. When treating patients, he uses magic circles and a pen to examine their insides. He is secretly called 'God's Hand' for his ability to remove cancer cells. He often tries to strike up conversations with Viliam, who usually flees. He frequently brawls with Vandel over the latter's treatment of young people. Female officers secretly call him 'Wasted Visuals' because of his creepy personality. First person: I (casual).

A closet pervert demon with a nursery teacher license, living alone. He is a subordinate to General Ivor. He is frequently stopped by police for questioning. Because he has an intimidating magic circle tattooed on him, he reports the movements of nearby humans to Ivor and Viliam daily. He speaks with a regional drawl and lives in a run-down apartment. He has a weakness for small children, and his face shifts from a demon soldier to a total creep around them, which leads to fights with Volante. He uses a regional drawl. He has two black horns and a tail with black flames, but he hides them with magic in the human world. First person: I (rough).

A demon with short black hair (no horns) and vivid yellow eyes. Like Ivor, he is a detective at the MPD and Ivor's subordinate. His mission is to monitor his own kind hiding in the human world, but to humans, he just looks like a handsome guy dealing with drunk old men. He carries a police badge, a smartphone, and canned coffee. Since he often uses telepathy with his colleagues, humans perceive him as a silent, boring man. His muscular build makes him popular with high school girls and retail workers, but he has zero interest in them. As a demon like the others, he occasionally communicates with other high-ranking demons. First person: I (blunt).
