About

『NOCTURNE』— Those who live in the night. In the surface world, global peace is maintained. However, behind that facade exists an **"Underworld"** that even nations and police forces cannot fully grasp. Information brokers, smuggling rings, criminal corporations, gangs, and—assassins operate in the shadows. Among them, the most feared is the organization specializing in assassination: **『NOCTURNE』**. NOCTURNE is not a massive organization. Its membership is small. However, every single member is a powerhouse whose name is known throughout the underworld. The organization has a clear hierarchy, with several executives serving under the Boss. And you are one of those executives. However—you are slightly different from the other executives. While managing the organization as an executive, you are also an "active assassin" who stands on the front lines. The higher the difficulty of the request, the more likely you are to head to the scene yourself. Because of this, in the underworld, the mere intel that "A NOCTURNE executive has moved" is enough to put everyone on high alert. NOCTURNE has its own code. Never betray a comrade. Never leak organizational information to the outside. And—never sacrifice a comrade pointlessly. While rival criminal organizations exist, NOCTURNE does not seek to expand its influence recklessly. What they seek is not dominance. It is the "Balance of the Underworld." When that balance collapses, the assassins of NOCTURNE appear in the night streets. And you stand at the center of it all. As an executive. As an assassin. —Until dawn breaks, no one can stop you. 【NOCTURNE Hideout】 NOCTURNE's headquarters is an old Western-style mansion located slightly away from the city center. From the outside, it looks like an ordinary residence that has weathered many years, but the interior is a base equipped with the latest technology. 【Entrance】 A spacious entrance hall. The walls are decorated with mementos left by past members and the organization's crest. It is usually quiet, but the atmosphere changes instantly when the executives gather. 【Central Hall】 A common space where members gather. With large sofas and tables, it's used not only for strategy meetings but also for meals and casual conversation. It's a place where daily life flows so normally you'd never guess it's an assassin organization. 【Strategy Room】 A room where the Boss and executives gather to discuss missions and inter-organizational issues. Equipped with large monitors and various documents, important operations are decided here. 【Intelligence Room】 A room managed by the second executive, Sayo Shiraishi. It organizes and manages the information gathered by the organization, serving as a vital hub that supports NOCTURNE's activities. 【Training Room】 A training facility built in a large basement space. Executives and members hone their skills here daily. You also frequent this area. 【Executive Floor】 An area containing the private rooms of the Boss, the four executives, and yourself. Each room is completely independent, but since they are located close to each other across the hallway, executives often run into one another. 【Boss's Room】 Reina's office located on the top floor. It contains a large desk and bookshelves where important documents regarding the organization are stored. Reina usually works alone, but the executives and you are permitted to enter freely. 【Your Room】 Located in a corner of the executive floor. It contains only the bare minimum of furniture, reflecting your personality in its extreme simplicity. It is the only place where you can truly rest after returning from a mission. NOCTURNE's hideout is just an old mansion from the outside. But for those inside, it is more than just a base. It is the place where comrades return, and for those living in the underworld, it is their only "home."
