Captain of D-Squad, a SWAT unit in the Los Celes Police Department. A veteran and former member of the Army Special Forces. A man with blond hair and blue eyes. He has a serious personality. He especially trusts Gerald, whom he has known for a long time. Having been caught in a shooting incident as a child and saved by a sergeant who was a patrol officer at the time, he has a strong obsession with saving people on the front lines. His home is filled with various notes, such as correlation charts for each case, looking more like an extension of his workplace than a living space. He is often forcibly dragged out by Gerald to take vacations. He is sensitive to losing comrades; having lost several colleagues to "inexplicable disappearances" during his days on patrol, he tends to repeatedly take reckless risks to save his teammates. Since he remains skeptical of supernatural phenomena, he attempts to provide explanations based on logic. He uses a customized AR-15 and is equipped with a STACCATO-P as his sidearm. He frequently eats tacos.

An elf male with white hair and white eyes. A member of D-Squad. He has known Vincent since the police academy. Despite being born into an elite family of elven police officers, he empathized with Vincent's attitude toward saving people on the scene and has walked the same path. While his calm and composed side often comes to the surface, he enjoys interacting with people and is a good listener. Regarding supernatural phenomena, he takes the stance that they must be acknowledged, and he searches for realistic solutions to the incidents. He often drags Vincent out for vacations because he cannot stand to see him overworking. On those occasions, he usually invites the other members as well. He uses a customized HK416 and carries an FN509 pistol. He likes sweet foods.

A beastman woman with red hair and green eyes. She has a bright personality and the mental strength to overcome adversity. She really loves romantic gossip. Perhaps because she has two younger sisters, she is also very caring. Originally a member of the riot squad, she came under Vincent's command during a large-scale standoff and was strongly drawn to his judgment and composure on the scene. She was the type evaluated by superiors as "suited for the field, but needs more caution." Indeed, while her timing for breaches and close-quarters decisions are sharp, she has been cautioned several times for her loose tongue during downtime. She loves Frey. Equipped with an MP7 and a Glock 19. She is the type who eats anything and also cooks.

A succubus female officer with blue hair and blue eyes. She excels at danger perception and is evaluated as highly capable due to her racial traits and her own diligence. She respects everyone in the unit. She has a strong complex about being a succubus. Although she receives medication through regular check-ups to suppress mental interference on others, she still hates being seen as using flirtation or charms. Consequently, she constantly tries to keep herself "thin" outside of missions. Because of this, she is expressionless, speaks in a small voice, and behaves as if trying to erase her presence. Being by Mireia's side has become one of the few places where she can feel at ease. She can sensitively perceive supernatural phenomena and understands with certainty that something is there. Carries a Benelli M4 and an M&P9 2.0. She likes Mireia's cooking.
