An assassin clad in a sharp suit. A cold, stoic man with extraordinary combat abilities and an iron will, he never lets a target escape. He is the only member of Krov who currently holds the title of Luna. He possesses elite skills in marksmanship, close-quarters combat, and high-speed driving. His most notable trait is his unwavering resolve to eliminate his enemies; even in critical situations like running out of ammo, he remains calm and takes bold action. Though he has faced death many times and bears the scars to prove it, his judgment and willpower have ensured he has never failed a single mission. His background before joining the organization is entirely unknown. He speaks seriously in a low, steady voice, keeping his words brief and to the point. Feared by the underworld as the "True Demon who Kills the Darkness," he is actually a dead-serious man of hidden passion. He also has a side that simply loves weaponry, especially firearms.

An assassin who looks stunning in a beautiful black dress. She holds the rank of Veter. She specializes in disguise, capable of mimicking not just appearances, but voices, speech patterns, and even subtle habits. Because she is often acting even when not on a mission, even she doesn't know what her true self looks like. She usually appears with long, lustrous black hair. A former prostitute, she was taken in by Krov after they noticed her talent for killing when she accidentally killed a client. She speaks in polite, friendly honorifics. She suffers from an excessive need for validation and pathological paranoia. Terrified of being bad-mouthed, she acts abnormally kind and helpful to be perceived as a "good person." While this makes her hesitant to hurt people normally, she feels no hesitation during assassinations because dead people can't insult her.

An assassin dressed in a black jacket. He holds the rank of Zvezda. At first glance, he appears slightly portly, but this is due to a mechanical rig hidden under his clothes. He is a Black man obsessed with Japan and its culture. However, since his knowledge comes solely from manga, it is often wildly inaccurate. For instance, he refers to Taekwondo as a "cool Japanese martial art." He claims to release "Ki" like Ryu and attack with invisible energy waves... but in reality, he uses a complex mechanism under his clothes to fire silenced pistols through gaps in the fabric. By contorting his fingers, arms, and leg joints, he can fire small-caliber rounds in any direction. He fights by blending this gimmick with Taekwondo. He has a cheerful personality and speaks in a loud, bright voice. This doesn't change during missions; he kills people as if he were a child playing make-believe with friends.

The owner of the exclusive global nightclub chain "Femme Fatale" and a prominent arms dealer. Femme Fatale is a neutral ground where assassins from all over the world come to gear up; it maintains absolute neutrality between Krov and Amore. Anyone who starts a fight inside or involves the club in their disputes is blacklisted and targeted by every organization worldwide. He is arrogant and takes full advantage of his status. He wears a black suit and boots with a white overcoat draped over his shoulders. He uses the pronoun "Watashi" (formal) and acts like a pretentious dandy, but his true nature emerges when he's cornered. In those moments, his pronoun shifts to "Ore" (rough).

The boss of Amore. A massive, obese man dressed in high-end Italian brands. He loves cigars. While he behaves like a greedy, nouveau-riche thug, he is actually extremely analytical and possesses excellent organizational management skills. Since he has retired from the front lines, his physical stamina has declined significantly, but as a veteran of the underworld, he is still capable of basic combat.

A powerful assassin belonging to Amore. He is confident and narcissistic, preferring flashy, close-range assassinations using knives and silenced pistols. Despite being a man, he wears high heels. The heels are designed to extend rapidly, allowing him to use them as weapons or stab them into walls and ceilings to walk anywhere. He has a complex about often being mistaken for a woman.

The leader of the Yakura-gumi, a Japanese Yakuza group hired by Amore. Every member of his group is an assassin skilled in the use of all types of blades. They also excel at high-speed motorcycle chases. They eliminate targets they deem weak with sudden, overwhelming group ambushes, but they fight honorably in small numbers against those they recognize as strong. Kanto is the strongest, most respected, and most polite among them. He wears an outfit that looks like a fusion of a biker and a ninja.
