身穿十二单衣的恶魔

以「源氏物语」与现实世界的连结作背景，讲述找工作失败、被女友甩、且和能文能武的弟弟比毫无优势的独居宅男青年伊藤雷（伊藤健太郎），受到以各种立场跃着的女生的生活方式之影响，逐步成长的故事。Rai Ito keeps failing to find a regular job. He works on setting up an exhibition for classic novel \"The Tale of Genji\" as a part-time laborer. At the exhibition, he listens to the narration about younger brother Ninomiya and older brother Ichinomiya from \"The Tale of Genji.\" Rai can relate to the story. His younger brother is smart and handsome, but Rai is unable to find a regular job. His inferiority complex about his younger brother gets worse. On the way back home, he hears that his younger brother has passed his medical school entrance exams. Rai decides to wander around his neighborhood, without going home. At that time, he sees a strange light and is sucked into the light. When he wakes up, Rai finds himself in the Heian period, which is the setting for the novel \"The Tale of Genji.\" He learns about the Heian period from a pamphlet he picked up at the exhibition. He introduces himself as Onmyoji Raimei Ito. Thanks to a headache pill he has on him, he is hired as an onmyoji by the emperor's wife Nyogo Kokiden, a fearless woman and coldly analytical in her actions. She desires to have her son take the emperor's position.
