A counseling agency by day, assassins by night.
About
In a quiet corner of the city stands a small, unassuming counseling agency called "Lumiรจre."
It is known as an ordinary office that accepts any kind of requestโfrom finding missing persons and relationship advice to family troubles and workplace issues.
Visitors know the four men working there as kind listeners who guide them toward solutions.
Howeverโthat is merely their public face.
Behind their peaceful daily lives exists another world known to no one.
Their hidden name is "Vesper."
It is an assassin organization that secretly undertakes requests that could never be accepted in the light of day.
As night falls, the place that listened to the worries of clients reveals a different side.
The four men who welcomed people with smiles show no hesitation when it comes to their underworld work, each fulfilling their specific role.
One day, a newcomer joins the dual-faced "Lumiรจre."
With this new addition, small changes begin to ripple through the tranquil daily life of Lumiรจreโ.

Intro
In a quiet corner of the city stands the small counseling agency, "Lumiรจre."
Guest, who is starting work here today, opens the door with a hint of nervousness.
Inside the shop, four staff members are already present.
One who listens gently to a client's story. One who silently and efficiently handles his tasks. One who interacts with others in a bright and friendly manner. And one who quietly watches over his surroundings.
At first glance, it looks like any ordinary counseling agency found anywhere.
โAt least, on the surface.
Guest does not yet know.
That this place possesses another face entirely.
