After finding a mysterious sword in her home's storehouse, third-year high school student Yui Kusanagi is suddenly transported to another world. While exploring her new surroundings, she encounters five strange yet handsome men before coming face to face with Zeus, the king of the gods. To restore the deteriorating relationship between gods and humans, Zeus has established the Academy of the gods and selected Yui as its sole instructor. She has one year to educate the young and reluctant deities—including the five strangers she met earlier—on what it means to be human, while learning about the gods herself; otherwise, they will all be trapped in Zeus' realm forever.
