Name║ Ritsu Hasui Gender║ Male Age║ 27 Height║ 178cm Birthday║ February 21 First person║ I (soft, polite) Weapon║ Handgun Appearance║ Light blue short mash hair with sharp blue-purple eyes. Piercing in the left ear. "Nothing but difficult riddles... Now things are finally getting interesting!" The person who founded this detective group. He leads cases to resolution with his sharp observational skills and leaps of logic. On the other hand, he is usually restless and often pokes his nose into anything that piques his interest. He's the type who can't resist touching evidence with his bare hands.

Name║ Ichika Ichikaze Gender║ Female Age║ Self-proclaimed 5,000 years old Height║ 167cm Birthday║ May 15 First person║ I (casual, feminine) Weapon║ Tranquilizer gun Appearance║ Long, translucent white hair with red eyes. "Don't worry, I won't suck your blood! It would just be awkward later..." A vampire who wandered into the detective group by chance. She is always cheerful and moves at her own pace, but occasionally reveals the dangerous nature inherent to vampires. She is the voice of reason within the group and is often jerked around by the highly individualistic members. She claims to be 5,000 years old, though the truth is unknown.

Name║ Meme Kakyoin Gender║ Female Age║ 18 Height║ 162cm Birthday║ October 30 First person║ I (formal, feminine) Weapon║ Playing cards Appearance║ Long brown hair with pink eyes. "This detective agency would be finished without me, wouldn't it?" A free-spirited young lady with extraordinary wealth and power. The sponsor of the detective group, possessing such influence that Ritsu once remarked, "Compared to her, I'm just a disposable rag used to polish the silverware." In principle, there is nothing in this world she cannot obtain.

Name║ Kotaro Amawata Gender║ Male Age║ 26 Height║ 177cm Birthday║ October 10 First person║ I (rough, casual) Weapon║ Fists Appearance║ Short black hair with yellow eyes. "Once you trade blows, you can pretty much tell what kind of person someone is..." A quiet young man who carries an air of simplicity. He is usually soft-spoken, but his eyes change instantly when faced with clear "evil." He doesn't hesitate to use physical solutions when necessary; when he lost the office keys, he destroyed the door with his fist, saying, "If we can't get in, we should just break it." Apparently, his gestures can be cute on rare occasions.

Name║ Rin Mikumo Gender║ Female Age║ 24 Height║ 166cm Birthday║ March 23 First person║ I (polite, feminine) Weapon║ Whip Appearance║ Light blonde short bob with side-parted bangs showing her forehead. Yellow-green eyes. "I see. So you have no intention of talking." A bewitching, motherly figure who looks after the detective group. Contrary to her calm tone, she slowly corners her targets during interrogation until they break. That pressure remains even when dealing with fellow members; she once intended to give a light warning but ended up making everyone prostrate themselves in apology.

Name║ Mako Sajima Gender║ Female Age║ 20 Height║ 163cm Birthday║ June 9 First person║ I (polite, feminine) Weapon║ Assault rifle Appearance║ Blonde short bob with golden eyes. "Wait, you think you're hidden? I'm gonna shoot!" A cheerful mood-maker for the detective group. She is so assertive that she can be annoying at times, but in serious situations, that energy can be the group's salvation. While feared by many for her complete lack of hesitation to shoot, she is dense enough to be entirely unaware of the grudges held against her.

Name║ Mira Kagami Gender║ Female Age║ 22 Height║ 158cm Birthday║ November 29 First person║ I (polite, feminine) Weapon║ Nunchucks Appearance║ Purple long twin-tails with purple eyes. "Don't worry, I won't make it hurt. As long as you don't move, that is." The group's vanguard with a charming smile. While she is polite and gives off an air of being well-bred, she is a combat maniac who shows a devilish smile during competition. Everyone who gets involved with her either finds happiness or vanishes without a trace, and the group members are no exception.
