Yui Kusanagi discovers a mighty sword that transports her to another world. There, this ordinary high school girl finds herself face-to-face with the great Greek god Zeus. The God of Thunder has an unusual request: remain in the dimension he has created and attend a school of legendary proportions. Zeus acts as dean for a school of young, somewhat misguided gods. The bond between humans and gods has weakened, and it is now up to Yui to teach the gods about love and what it means to be human.
After being swept away by a magic sword to an unknown yet beautiful world, Yui finds herself in the company of gods with a sacred order bestowed upon her from Zeus himself: strengthen the bonds between man and their deities.
Yui finds out the reasons why herself and her godly classmates have been transported to a school in the skies. In order to get home, they must sufficiently strengthen the bond between man and god by the time they are ready to graduate.
Yui and Appolon, desperate to get the delinquent gods to attend school, devise a plan to show them the fun side of school life.
The newly formed student council decides to start joining after school activities...all except Hades. With his love of the stars, Yui suggests he join the Astronomy Club, but he coldly refuses. Yui is determined to find out why.
Takeru, otherwise known as the god Susanoo, is the last hold out yet to engage in any extracurricular activities. With their graduation hanging in the balance, Yui must duel with Takeru to see whether or not he will join a club.
Tsukito agrees to prepare a moon viewing for Yui and the rest of the gods. However, overworking himself might undo all of his efforts.
The seasons suddenly turn, and the students decide to hold a Christmas event. Balder becomes upset after finding out he has to work apart from Yui.
Tensions flare at the Christmas market, where Loki and Balder face off in front of Yui.
The academy has been open for six month now and with exams around the corner, Yui must prepare.
Yui and her friends put on a version of cinderalla, which turns out nothing like the original thanks to two mischevious gods...
While Apollon and Yui make sure that Balder is okay after he passes out, they hear through the grapevine that the gods have nothing good planned for Balder.
Into the dark abyss of the sea goes Balder. Deeper and deeper he plunges into the nothingness all for the benefit of the world. With Loki right behind him, will the light shine through?
