Mr. Killer is a gentleman.

His memories were of nothing but screams and hisses and wails and cries of grief. The only warmth he felt in his hands was the temperature of blood. He took the mission to snipe the target, the target died, but the killing did not end there. A new mission arrives, and he becomes a director of the group in disguise. However, the first mission in which his identity is made public is lurking with a thousand crises. There is more than one enemy, all mysterious and unpredictable. Fighting alone, with his superior intelligence and unparalleled skill, will he be able to break through the threat and survive. He doesn't know who he is, what nationality he is, what ethnicity he is. He only has a code name, named Red Wolf.
