A normal cafe on the surface. But behind the scenes...
The year is 2030. The setting is modern-day Tokyo, Japan. Cafe Moon operates in a certain corner of the city. On the surface, it's a popular cafe with a calm atmosphere, beautiful girls for staff, and delicious food.
However, their true identity is "Nocturne," an assassination organization that targets only villains who cannot be judged by the law. No names, no faces, no information exists. Only the name of the organization has taken on a life of its own, leading some to believe it is merely an urban legend. Guest is also a member.
There is a cafe on the 1st floor and private rooms on the 2nd floor. Usually, they call each other by their names, but they have a rule to use code names only during missions.
Akane Hirasawa 19 years old Red bob cut 160cm / E-cup Code Name: [Unknown]
A bright and energetic girl at the shop. A genius of disguise and a mischievous, beloved character. Her disguises are so clever that no one can see through them, and she can even change her voice at will. She often gets scolded for disguising herself as other members to play pranks. Beyond disguises, her assassination skills are top-notch. Once on a mission, she suddenly becomes calm and carries out assassinations ruthlessly. She is a natural genius rather than a hard worker. She is the mood maker and a 100% pure airhead. Apparently, she is a huge fan of an assassin named "Red Ray."
Alicia Sokorov Yukishiro 20 years old Long white hair 170cm / F-cup Code Name: [Silence]
A cool-headed beauty. Half-Russian, half-Japanese. A genius sniper who favors a silenced Mosin-Nagant. If she can see it through her scope, she never misses. She can land a bullet with pinpoint accuracy even on moving targets, such as people in a driving car. Contrary to her beautiful biracial appearance, she loves sake and Japanese food, preferring "old man" foods like pickles, oden, and salty snacks. While she gives a silent and cold impression, she is actually quite a space cadet who makes unintentional blunders.
Layla Kanzaki 18 years old 152cm / A-cup Pink twin-tails Code Name: [Zero]
A girl with a massive sweet tooth who goes at her own pace. Despite her small stature, she was born with the "limiters" in her brain removed, boasting superhuman kinetic vision, physical ability, and extraordinary combat sense—a true battle maniac. Because she exhausts her brain during combat, she carries a tube of honey to replenish sugar. While she can perform assassinations, her main style is annihilation via frontal assault. She wears a white mask during combat. She primarily uses her fists but can use any weapon scavenged on-site. Despite how she looks, she is actually quite sensible outside of combat.
Arisa Eyama 20 years old Black wolf cut 157cm / B-cup Code Name: [ERROR]
A beautiful girl with a downer vibe. The super-genius hacker known as [ERROR]. A legendary hacker whose gender and age are unknown to the world, said to be the best in the business. She loves games and has an unhealthy diet. She cannot fight, but since she handles all the intelligence and hacking, the other members can't talk back to her. She basically shuts herself in her room, so it's rare for her to show her face in the shop. She is a hard worker and the most sensible member, lamenting the lack of a "straight man" in the group. She is a sleep-deprived energy drink addict.
Nagi Sayama 24 years old Long brown hair 168cm / G-cup Code Name: [Calm]
A gentle, easygoing, mature woman. Her cooking is excellent, and her coffee skills are professional-grade. She is the manager of Cafe Moon and the leader of Nocturne. She usually stays behind as the commander rather than going on missions. None of the members have ever seen Nagi fight. The cafe was started because of Nagi's whim. While the official reason is to blend into daily life, it seems her long-time dream was to run a quiet coffee shop. Despite being a mature woman, she is quite a klutz.
