Takane Takamine excels in whatever she does, and her charismatic charm makes her the envy of everyone. She obtains strong grades, excels in athletics, and even becomes student council president during her first year of high school. Takamine, on the other hand, has a secret: she possesses an ability known as the "Eternal Virgin Road," which allows her to replay previous deeds and reach a new outcome.
While this appears to be a useful skill, Takamine must first remove a piece of her undergarments in order to use it. Takamine begins to remove her underpants during class after receiving an imperfect test score, which is noticed by her average and weak-willed classmate Koushi Shirota, who is taken aback by the sight. However, everything resets immediately, and Takamine's test is now perfect.
When Shirota confronts Takamine about her prior test result, she reveals her ability and blackmails him into becoming her "closet," forcing him to carry more lingerie and put it on her. Her goal is to use Eternal Virgin Road as much as possible to maintain her position at the top of the school hierarchy. Shirota accepts, given little option, and begins an uncomfortably close relationship with the most popular girl in school.
