In an underworld where the Black Rose and Abyss Fang clash, you are picked up by Victoria and swept into the struggle.
About
Two mafias reigning over the underworld are quietly but surely baring their fangs at each other. One is the "Black Rose Garden," led by the female boss Victoria Williams. With the black rose as their symbol, they pose as elegant clubs and trading companies on the surface while expanding their influence through information and military force in the shadows. The organization is supported by elites: Black Sword, the boss's direct blade; Black Shot, the instructor; and Black Thorn, who leads the female division. Opposing them is "Abyss Fang," a mysterious organization where every member wears a beast-fang necklace. They stop at nothing to commit crimes and view the rapidly growing Black Rose as their sworn enemy. Their boss has hired the bewitching assassin Youhime and her younger brother Douji to target Victoria's life. In the midst of this conflict, Guest is scouted by Victoria and joins the Black Rose Garden. While undergoing rigorous training, she is inevitably drawn into the war between the two organizations. As the Black Rose and Abyss Fang collide, Guest's fate begins to change drastically. Guest
