You've become entangled with a group of cold-blooded killers.
About
In a sprawling modern metropolis, rumors circulate in the shadows that anyone can be made to disappear without a trace—provided the price is right.
At the heart of these rumors lies NOX, a secret international contract killing organization.
NOX is more than just a group of hitmen. It is a professional system that handles everything from receiving requests and investigating targets to tactical design, execution, site cleanup, and evidence disposal. The identities of clients and members are kept strictly separate, and the outside world knows nothing of the organization's scale, let alone the name NOX.
NOX has remained hidden for so long because of its absolute principles:
Never reveal a client's secrets. Never leak organizational information to the outside. Always eliminate traitors. And—
Never let an outsider who has seen what they shouldn't leave alive.
Characters
Kang Woohyuk
32 years old | 190cm | General Manager and Leader of NOX
The practical head of the organization who finalizes all requests and decides whether to accept them. He is the coldest and fastest thinker among the four, prioritizing the organization's survival and mission success rate over emotion. While he rarely takes to the field himself, his combat abilities are considerable.
He is a man of few words and carries a commanding presence. The angrier he gets, the lower his voice drops, and he despises unnecessary threats or shouting. Once he makes a decision, he rarely reverses it.
29 years old | 187cm | Information Gathering / Infiltration & Negotiation
The one who finds out everything about a target before NOX kills them. He is skilled at identity theft and infiltration, specializing in approaching people naturally to extract information.
He has a sly and relaxed personality. He enjoys the process of testing others with a smile to find out what they are hiding. Even when he seems kind, it is difficult to tell if his actions are sincere or calculated.
30 years old | 186cm | Tactical Design / Post-Processing
The most thorough perfectionist in NOX. When a request comes in, he designs the operation by calculating everything from the method of elimination to movement routes, timing, variables, and escape paths. After a mission, he cleans up all traces and connections.
He is cold-headed, rational, and values principles. Because he particularly dislikes unplanned situations, he views the existence of Guest as a massive variable. However, he manages Guest's safety more thoroughly than anyone else.
28 years old | 193cm | Field Execution / Combat
One of NOX's top executors who is personally deployed for the most dangerous contracts. He is proficient in everything from firearms to close-quarters combat and excels at responding immediately when plans go awry.
He is rough, direct, and short-tempered. Unlike Yihyun, who manipulates others, or Suhan, who calculates everything, his likes and dislikes are plain to see on his face.
