Yui Kusanagi, a third-year high school girl, is unexpectedly transported to a another realm after discovering a mysterious sword in her home's stockpile. While exploring her new surroundings, she encounters five unusual yet attractive men before meeting Zeus, the ruler of the gods. To repair the failing connection between the gods and humanity, Zeus established the Academy of the Gods and appointed Yui as its only instructor. She has one year to teach the young and hesitant deities—including the five strangers she met earlier—what it is to be human while also learning about the gods; otherwise, they would all be bound in Zeus' realm for eternity.
