To say that Mona Kawai is cute would be an understatement; she is breathtaking in every single way, and she knows it. At school, she is fawned over by boys and girls alike, and she graciously welcomes it all as a natural reaction to her irresistible charm. That is, until she comes across Medaka Kuroiwa, the boy who is seemingly immune to her overwhelming charisma. She goes out of her way to talk to him and even dials her cuteness up a notch, but no matter what she tries, Mona cannot wipe the scowl off Kuroiwa's face. Backed into a corner, Mona is forced to use the most devastating weapon in her arsenal: her physical allure. Such drastic measures would leave other boys foaming at their mouths, but Kuroiwa remains unfazed by her attempts. Little does Mona know that the only reason Kuroiwa just barely abstains from succumbing to her charms is because he is training to be a monk and thus trying his best not to be held down by worldly pleasures. As Mona goes all out to entice Kuroiwa, she fails to realize that his unintentional chivalry might just make her fall for him instead.

Second season of Hyakka Ryoran: Samurai Girls. The series takes place in an alternate version of Japan called Great Japan (大日本国, Dai Nippon-koku), in an alternate timeline where the Tokugawa shogunate remained active and has remained semi isolated from the rest of the world after their defeat by American forces in World War II. And the Americans have bases on Okinawa and southern great Japan. The story takes place at Buou Academic School (武應学園塾, Buō Gakuen-juku), an academy located at the base of Mount Fuji where children of military families train to become samurai warriors. The academy is in the middle of a power struggle between Yukimura Sanada and Matabei Goto of the Toyotomi faction and the powerful student council that rules the school, and Muneakira Yagyu, the owner of the Yagyu Dojo, and the mysterious Jubei Yagyu are dragged in the middle of the conflict.

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.

Nagomu Irino returns to his Kyoto home for the first time in ten years when his father is hospitalized. Nagomu is eager to take over Ryokushou, the family's Japanese sweet shop, but he's instead asked to be a father figure to Itsuka Yukihira, the girl everyone calls the successor.
