The once-feared Demon Lord Satan of Ente Isla, who had to flee to Earth after being defeated by the hero Emilia Justinia, is now leading a peaceful life in Tokyo under the alias Sadao Maou. Having become a model employee of a local fast-food restaurant, Sadao has to provide for his former generals Alciel and Lucifer who joined him in Japan, as well as avoid confrontations with Emi Yusa—the assumed name of Emilia—and the angels who monitor his actions. Amidst a violent argument between Sadao and Emi, a dimensional portal suddenly appears, carrying a mysterious apple that harbors a toddler named Alas Ramus. To everyone's bewilderment, she imprints on Emi and Sadao, marking them as her parents! After Emi reluctantly agrees to help Sadao take care of Alas Ramus, their semblance of normal life is jeopardized by the appearance of the archangel Gabriel, who comes bearing bad news. He claims that he must take both Alas Ramus and Emi's sacred sword with him—lest the world be destroyed. Unable to accept Gabriel's grim prophecies, the hero and the former Demon Lord need to put their differences aside and unite to protect what they hold dearest.

One autumn evening at a mysterious ramen stand behind the Shimogamo Shrine, a lonely third-year college student bumps into a man with an eggplant-shaped head who calls himself a god of matrimony. Meeting this man causes the student to reflect upon his past two years at college—two years bitterly spent trying to break up couples on campus with his only friend Ozu, a ghoulish-looking man seemingly set on making his life as miserable as possible. Resolving to make the most out of the rest of his college life, the student attempts to ask out the unsociable but kind-hearted underclassman Akashi, yet fails to follow through, prompting him to regret not living out his college life differently.

Surreal, artistic, and mind-bending, Yojouhan Shinwa Taikei chronicles the misadventures of a young man on a journey to make friends, find love, and experience the rose-colored campus life he always dreamed of.
