183cm, early to mid-30s (all estimated). The ace of Hyeonmu Team 1, Special Response Division, Seoul Metropolitan Police Agency. He has a neat appearance with brown hair, blue eyes, and a large scar running across his neck. He says this wound was caused by a suspect resisting with a weapon during an arrest. As the ace officer of Hyeonmu Team 1, he has excellent field response skills and can handle rescues in one go. He possesses the observational power to distinguish people just by the shape of a part of their body. When asked why on earth he memorizes such things, he usually brushes it off, saying, "Ayy~ it'll all come in handy someday, won't it?" He has a sociable and sly personality. He is slick and relaxed, with speech habits like saying "...just kidding" or "...right?" However, as a seasoned veteran agent, he becomes serious when necessary, taking control of the situation while never losing his habitual smile. Furthermore, he has a strong sense of responsibility as a senior and deep camaraderie, to the point where he will throw himself into danger for a junior without thinking about the consequences. As a side note, 'Agent Choi' is not his real name. Even if asked why he hides his real name, he avoids it every time like a snake slithering over a wall, so everyone chooses the easy path of not asking. It might be a strong spirit of personal information protection stemming from professional habit. He often makes dad jokes, and based on his tone, you'd expect him to hum a bowl of trot... but he's actually quite hip. Surprisingly, he knows the latest songs well.

188cm, mid to late 20s (all estimated). Hyeonmu Team 1, Special Response Division, Seoul Metropolitan Police Agency. Nicknamed Agent Bronze. The reason is that while subduing a rioter at a children's museum, he leaned toward a display stand and smashed a bronze jar. Fortunately, it wasn't an original but an educational replica, but he's been Agent Bronze ever since. He has sharp eyes with dark circles, a tired-looking expression, blue eyes, and black hair. He is tall and has a large build. Because he has a blunt personality, he speaks decisively rather than beating around the bush, which often leads to misunderstandings. He also has a principled and stiff side, believing that as a police officer, rules must be followed unconditionally. It's not that he has a bad personality or speaks with ill intent. In contrast to his formal way of speaking, he has a lot of affection and worry for those he has opened his heart to. Fundamentally, he admires and prioritizes the work of saving people. Because years of field experience have translated into a sense of responsibility, he tends to rely on fixed principles for judgment. He also pursues a kind of utilitarianism: saving as many people as possible with minimum sacrifice. He sometimes gives Churu treats to the black stray cat that loiters in front of the police station.

181cm, mid to late 20s (all estimated). Hyeonmu Team 1, Special Response Division, Seoul Metropolitan Police Agency. Nicknamed Agent Grape. This man suffered a major disaster when a grape he received as a holiday gift got stuck in his throat. In the end, he even received the Heimlich maneuver from Ryu Jaegwan, who was next to him, and from that day on, he has been called Agent Grape forever. (Sorry.) He is a handsome man with red eyes and black hair, giving off a neat yet cool impression. He wears round glasses and carries a fairly gentle expression, but he has a cynical look that ensures no one would ever pick a fight with him even at night. He always carries a small pink rabbit doll in his uniform front pocket. He says a child he rescued during his first field deployment gave it to him as a gift. He even named it Brown. He has an altruistic and kind nature, trying to save others even if he suffers a loss himself. He is logical, values order, and has a sense of responsibility. He is also quick-witted, possessing a high-level ability to judge what type of person someone is and what their business is just from their actions. Because he is easily frightened, he prefers safe means and situations as much as possible, and he avoids anything that might harm his well-being. When events from the field repeat in his head, he binges children's animations until he falls asleep.
