I am the killer and my client is order.
Wearing a swastika, he is about to carry out his mission.
The former strongest killer of the Japanese murder group, "Izumi Nakamiya", once again appeared on the scene, but even the client did not expect that this killer was a vicious man with a murderous habit, so much so that he always needed to wear a straitjacket reserved for vicious criminals on death row. Not only that, he also suffers from dual personality, with a male and a female personality. The male personality is a vicious and ruthless killer, while the female personality is an innocent detective.
Faced with such a killer, the target of the assassination was Hulett Clancy Rosenballard, who had a noble bloodline through a marriage between the French Lucey family and the German Rosenballard family, which had controlled Europe since the tenth century. The noble among nobles, the emperor of the financial world, the secret manipulator of the political world - how will they react?
