Shungo Ninomiya is just an ordinary, run-of-the-mill high school student who lives at home with his older sister Ryoko—at least when she's not away doing her job as a mercenary. However, Shungo's life ceases to be normal the moment a cute girl named Mayu Tsukimura descends into the middle of his school's campus in a military-grade helicopter. It turns out Ryoko sent this girl, along with her older brother Mikihiro, to live at the Ninomiya household. But the newly-arrived siblings are a little special: Mayu is, in fact, a succubus and her brother, an incubus! And as if the circumstances are not problematic enough, Mayu is crippled with androphobia—the fear of men—and it's up to Shungo to help her overcome this at the behest of his sister. Ryoko plans to force Mayu to be closer to Shungo, and to do this, she’ll employ some questionable methods such as having them share the same bed and even take baths together. The situation further complicates when student council president Reika Houjou arrives as the new maid of the Ninomiya family, and she will stop at nothing to thwart Shungo and Mayu’s sexually-geared training. With the sudden arrival of all these oddities, Shungo's ordinary life is about to be thrown into utter turmoil. [Written by MAL Rewrite]

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.
