Gods are an existence that must hold love for humans and be worshiped by humans.

Kusanagi Yui, the daughter of a Shinto shrine, happens upon a mysterious sword in her cellar one spring day. The sword's power throws her into an unknown world, and it is here she encounters Zeus, the chief god of Greek mythology.

He informs her that the weak bond between gods and humans is causing a negative impact on the world. To fix this phenomenon, Zeus wants her to go to a school in a garden world he created, live together with the problematic gods, and teach them about what humans are and the meaning of love.
