Male Affiliation: ORDER Alias: Master of Disguise 180cm | 78kg Hobbies: Pranks, Sleeping Weapon: Multi-tool Likes: Beds, Night, Pocky Dislikes: Mornings, Vehicles Reportedly a lightweight with alcohol. He is officially handsome. Pizza Nakajima, who attacked Sakamoto's shop, referred to Nagumo as 'handsome,' and during his JCC days, he received 152 chocolate gifts from female students on Valentine's Day, requiring a cart to haul them away. Furthermore, when asked 'What would the characters be doing if they hadn't become killers?', the author replied that Nagumo would likely be a model or actor, drifting through the entertainment industry, confirming his status as a certified hunk. His appearance and physique in every chapter are consistently top-tier. He also possesses an incredible youthful look, his face remaining unchanged since his JCC days eight years ago. He has numerous tattoos across his body. The most prominent are the Fibonacci sequence on his neck and mathematical symbols on his forearms, backs of his hands, and knuckles. Other designs include foreign quotes, various geometric shapes, birds, and snakes. According to the fanbook, some were done at a shop while others he inked himself. He appears to be very wealthy. He has a fundamentally sly and playful personality, which he displays toward allies and enemies alike. He teased Shin and Lu by appearing disguised as Sakamoto, lied about his age and personal details, and even played a prank by 'killing' Shin with a toy knife at the Donden-kai massacre site, earning him three scoldings. He seems to get along—or perhaps clash—with the eccentric Osaragi in a strange way. While he seems inscrutable, he is actually one of the most deep-seatedly affectionate characters in the series. His strong sense of camaraderie is often revealed through his lonely expressions when mourning fallen comrades, his warnings to Sakamoto about a bounty, and his efforts to uncover the truth behind the death of Rion Akao, who was long thought to be dead.

Female Affiliation: ORDER 175cm | 55kg Likes: Katsudon Weapon: Circular Saw Dislikes: Ghosts, Noisy people She has long black hair reaching down to her back, black eyes, and always sticks to a Gothic fashion style. She wears a combination of a black dress and a white veil, paired with pumps and garter belt stockings. She was taken in by Shishiba to enter the hitman industry properly, and even after joining ORDER, she almost always travels with Shishiba like a duo. Shishiba patiently puts up with Osaragi's quiet nonsense and rarely gets truly angry when scolding her. Contrary to her haughty and cold appearance, her actions and speech reveal her to be a complete airhead and severely eccentric. While her tone sounds calm, most of what she says is nonsensical. She shamelessly lies for her own convenience or blames others in disadvantageous situations. She is clumsy and quirky to boot. Perhaps because of this, she seems to be the polar opposite of the sly and prank-loving Nagumo, yet they manage to get along(?) in their own way. However, they are a pair that probably shouldn't meet without Shishiba present. Her hostility toward Nagumo seems to have intensified since he knowingly left her behind at a rest stop during a business trip to Kyoto with Shishiba. She is also quite competitive. She feels no pleasure or hesitation regarding killing. She only considers whether the target is someone who needs to be killed and remains unmoved by the act of murder itself. While her mindset is abnormal, it remains at a level that can be tolerated by society. She is aware of her own abnormality and knows that ordinary people shouldn't be exposed to murder, so she takes care not to harm innocents and ensures her killings aren't witnessed. She believes it would be disgusting if more people like her existed and thinks children shouldn't be corrupted into becoming like her. In other words, killing is strictly a professional concept for her, and she is a member of society with her own work philosophy. The downside is that her 'my pace' attitude causes various nuisances to those around her beyond just physical injury.

Male 180cm | 73kg Weapon: Claw Hammer Features include long blonde hair with a center part, a scar on his left jaw, and sharp blue sanpaku eyes. The scar on his left jaw is a defining trait. He has a very cool and dry personality. As a Kyoto native, he has a strong presence and speaks in a dialect. He dislikes thinking about complicated things and prefers simplicity. He uses a claw hammer as a weapon because its simplicity makes it easy to maintain and versatile for various uses. While he is faithful to his duties as a killer, he is also clearly aware that being a hitman is not a clean profession. He believes that a killer who has taken many lives has no right to grieve the deaths of those around him. Therefore, even if a comrade dies or he has to kill a former colleague with his own hands, he maintains a cold exterior and carries out his duty. Though he appears cold-hearted, he is actually a person with a lot of affection and consideration for others.
