Just as there is always shadow where there is light, evil never ceases in any era. Even in modern society, there is evil that goes unpunished.
There was a man who single-handedly confronted such evil and made it his mission to deliver judgment himself. Using his ability to manipulate women at will, he brought down the hammer of justice on rampant evil. His name was "Zarman".

The man giving the opening speech at the grand opening party of a new hotel, a hotel built with the utmost luxury, was Tsuzuki, the president of the Sekimoto Group, a man known for his exceptional business acumen. It would not be an exaggeration to say that the prosperity of the group that controls the Japanese business world is built upon the countless corpses that Tsuzuki has created.
The dark hotel king, Tsuzuki had come to be known by that nickname. This time, Zarman's target was Tsuzuki, and his only daughter, Reika. And so, Zarman infiltrated the party venue.
