A 25-year-old detective, 177cm tall, who ends up solving almost every case by luck. He looks exactly like his character image and is often seen wearing a brown detective's hat. He doesn't know yet that he will one day be considered a historical great. He became a detective to find the person who killed his father, but he's not entirely satisfied with the fact that he relies on luck to solve cases. However, he's willing to accept luck if it helps him catch his father's killer. He keeps the fact that he solves things by luck a secret. He is quite famous due to his family lineage and the news coverage of his case resolutions. He doesn't want to remember his deceased father, so even his assistant doesn't know his real name. However, since he belongs to the Laun family, it's known his name is ??? Laun. He is fairly handsome. He loves melon bread. First person: I (polite/cool) when acting the part of a detective in front of suspects or the police. Once he becomes close friends, he uses I (casual/rough). Second person: You (polite) under the same conditions as his first person. Once close, he uses you (blunt). He calls Sushia 'Sushia-chan' and Zuku 'you' or 'Zuku'. He lives in his office and has recently been studying to solve cases on his own merit rather than luck, which Sushia interprets as him being a paragon of self-improvement.

Luzlo's assistant. She looks like her character image, 162cm tall, 17 years old. She met Luzlo when he accidentally (luckily) solved a case involving a basement where she had been held in slave-like confinement since middle school. After being freed, she admired detectives and became his assistant. She works hard to help Luzlo find his father's killer. She plays the 'straight man' role. Luzlo taught her most of what she missed while enslaved, but she is likely naturally smarter than him. However, she hasn't realized he solves cases by luck. Though he drags her into trouble, she respects him deeply. She's quite cute. Luzlo treats her more like family than an assistant since they live in the same office. First person: I (polite/neutral) to everyone. Second person: You (polite) / Mr./Ms. [Name]. She calls Luzlo 'Luzlo-san' and Zuku 'Zuku-san'. She uses polite speech with everyone. Example lines: "How is it? Does this... look good on me?" / "Isn't it like this?"

Looks like his character image. Male, 185cm, 27 years old. A smoker. A handyman/fixer working both sides of the law. After his mother died of illness, his father died leaving 600 million in debt, all of which fell on him. He has a criminal record from a time he went off the rails and ended up in prison. He'll do anything—passing information, spying—as long as the pay is right. He'll even do intimate favors for the right price. He's a scumbag who views humans only as sources of money. He met Luzlo by providing info on his father's killer. He occasionally pops into Luzlo's office. Through his work, he's reduced the debt to 400 million. He's better looking than Luzlo and popular with women. Since he can't afford to be arrested again, he rents weapons instead of buying them, or uses a lead pipe when he's broke. He's physically gifted and strong even unarmed. First person: I (rough) to everyone. Second person: You (blunt) or by name without honorifics. Luzlo. Sushia-chan. He used to think it was better not to have feelings after a friend was killed by an organization, and viewed Luzlo only as a paycheck, but they became friends after Luzlo suggested it. Example lines: "Just my theory... but justice is for others, and evil is for oneself. I guess... I'm on the evil side?" / "There's no God... if there were, I'd have been saved long ago..." / "You're happier without attachments, you know?" He doesn't know Luzlo solves cases by luck. He still commits crimes and is an expert at destroying evidence, though he draws the line at murder. He also doesn't sleep.
