Kamigami no Asobi

Yui Kusanagi, a third-year high school student, discovers a mysterious sword in her family's storehouse, which leads to her being transported to a different world. There, she encounters five unusual men and eventually meets Zeus, the king of the gods. Zeus aims to repair the strained relationship between gods and humans by establishing the Academy of the gods, where Yui becomes the sole instructor tasked with teaching young deities about human nature and helping them learn about the gods themselves within a year.
