A number of people with similar base arrangement to wolves' have been discovered in the process of antidoting DNA of mankind of near future.
Many of them are found mainly among people with superb physical performance like athletes or mercenaries and they have prominently shorter life spans than others have.
A multinational medicine-manufacturing conglomerate "Paien", which developed a new medicine "Epoxyn" for a disease "Diewolf syndrome", also develops "Anti-Epoxyn" that has opposite effect in profound secrecy and supplies to the France military. The France military established a special force "WolfTeam", also known as the 2nd foreign legion, and recruits unit aiming worldwide.
The only draft requirement is basic physical test and a blood test in order to see if it suitable to "Anti-Epoxyn". Ages and physical ability of drafted members do not matter and they are free to commit and kind of crimes in their own countries according to the traditional rule of the foreign legion. "WolfTeam" is a super force with greater-than-human performance using power of "Anti-Epoxyn" and nobody is able to stop "WolfTeam" in military tactics and espionage.
The fame of "WolfTeam" gets bigger and bigger but the France military finds "WolfTeam" is going out of control.
They often commit unnecessary murder and devastate the region even after they have completed their mission and once a blood bath starts, they won't listen to any commands. One day, 7 of "WolfTeam" members get killed combating each other outside mission area.
Military police and researchers from Paien who were dispatched to solve this issue get assassinated and every single member of "WolfTeam" burrows out of military's sight. "Wolfteam" members live on as mercenaries for their life and fight against the chase of France military on the other hand.
