Weiss Kreuz (pronounced “vice kroyts”) is the story of four young men—Aya, Youji, Ken and Omi—who work at a flower shop. However, that’s merely their day job. By night, the four of them are an assassin team known as Weiss.

In Japan, things aren’t what they seem. Evil organizations and corrupt politicians are pulling the strings behind some of the most sinful operations the country has ever seen. Innocent people are being used, murdered, and even experimented on. However, the people responsible are out of the reach of the police. They are free to do as they please and to destroy as many lives as they want.

Well, at least they were. With the formation of Weiss, evil has something to fear—itself. Weiss has arrived.

Weiss is a group of four men that will kill without a second thought. They are a necessary evil, who commit the act of murder to prevent suffering.

Weiss receives missions to target and kill certain key members of corrupt organizations, thereby eliminating evil from its roots. Of course, things are not what they seem to be, and sometimes the people calling the shots are merely pawns themselves.
