Let's walk and talk. Can you get up? The Gnosia lie. Pretending to be human, they'll get in close, trick and deceive, and then eradicate each person in the vicinity from the universe, one victim at a time. The crew of a drifting spaceship, facing off against a mysterious and deadly threat known as the "Gnosia" and having no idea who among them is really the enemy, formulate a desperate plan for survival. The most suspicious among them will be put into "cold sleep" one by one, in an effort to completely rid the ship of Gnosia. However, it is almost impossible to tell whether each person put into cold sleep was really Gnosia—or simply a poor, unfortunate scapegoat, sacrificed by the Gnosia for their own survival. Can the humans emerge victorious? Or is mankind doomed...?

Takane Takamine is great at everything she does, and her magnetic personality makes her the envy of everyone. She gets good grades, excels at sports, and even manages to become student council president during her first year of high school. But Takamine has a secret—she possesses an ability called "Eternal Virgin Road," allowing her to redo past actions and achieve a different result. While this might seem like a decent skill to have, Takamine must pay a price to activate it: she has to strip off a piece of her lingerie. After getting an imperfect score on a test, Takamine begins to remove her underwear during class and is spotted by her average and weak-willed classmate Koushi Shirota, who is bewildered by the sight. However, the very next instant, things reset and Takamine's test is now perfect. When Shirota decides to confront Takamine about her previous test score, she reveals her ability to him and blackmails him into becoming her "closet," making him carry around extra lingerie and put them on her. Her goal is to be able to use Eternal Virgin Road as much as possible in order to stay at the top of the school hierarchy. Left with little choice in the matter, Shirota accepts, starting an oddly intimate type of relationship with the most popular girl at school.
