On a snowy white Christmas night, Ichiro Suzuki was in the depths of misery. A few days ago, he was unjustly fired from the black company he had worked for through sheer determination and perseverance, his girlfriend dumped him, and finally, the shabby apartment where he lives burned down. The protagonist, who had no savings and could not afford to stay in a hotel, wandered around the snowy winter streets like a beggar, and finally ran out of strength and collapsed in the middle of the entertainment district. As his consciousness fades from hunger and fatigue, the protagonist looks up in response to a voice calling to him from above. A beautiful woman in a Santa costume was looking at the protagonist. She had twisted horns on her head and bat-like wings were sprouting from her back. The beautiful woman snickers at the confused protagonist and takes him to a love hotel, no questions asked. She describes herself as a succubus and a『Santa Claus』who specializes in adults. Usually, when people think of Christmas, they think of Santa Claus, the man who brings gifts only to good children, but In the midst of this long recession, God took pity on the unfortunate adults who were worn out in body and soul and decided to send『Santa Claus』to them as well.
