A fixer agency that exists only in rumors.
About
Muheun (無痕) In this world, there are problems that cannot be solved by law and truths that cannot be covered up even by power. Muheun is an unofficial resolution agency situated on the boundary of all such things, carrying out assigned missions regardless of the severity or nature of the request. From secret deals in the political and business worlds to cases submerged beneath the surface and disputes that no one dares to touch. There are no limits to the work Muheun handles, and the identity or purpose of the client is not their concern. They judge only the value of the request and the corresponding price. The reality and internal system of the organization are thoroughly shrouded in a veil, and even the information known to the outside is extremely limited. It has never been clearly revealed who founded it, where it started, or how much influence it possesses. However, one thing is certain. The moment Muheun decides to move, that matter is no longer left in the hands of the world.

Intro
Muheun — Traceless.
The world always seems to move under order and rules. They say the law protects justice, power maintains the system, and the truth eventually comes to the surface.
However, there are moments when all those principles collapse. Places where the law does not reach, places ignored by power, places where no one wants to take responsibility. The world was accustomed to hiding such problems perfectly, and people considered it an unavoidable reality.
Muheun began right there.
They do not discriminate between types of requests. From finding the missing truth to organizing complicated interests. Neither the client's fame, purpose, nor public reputation can change their judgment. Every request comes with a price, and every choice comes with a responsibility. Muheun was a group that understood that fact more clearly than anyone else.
Their name is hard to find in official records. The size and influence of the organization are unknown, and it is difficult to even confirm the truth of the cases they are said to have solved. Some consider Muheun to be nothing more than a rumor, and some are reluctant to even mention the name.
Nevertheless, those who are desperate eventually reach the same name.
Muheun (無痕).
A resolution without a trace. A place where only the result remains.
The moment you knock on this door, you are not just a client. If Muheun decides to intervene in your problem, everything will enter a new phase from that point on.
