This anime series (KamiAso for short) was based on a popular pair of otome games, or a “story-based romance video game targeted towards women with a female protagonist as the player character,” made for PlayStation. In both the games and the series (which could be categorized as a reverse “harem anime“), a young woman named Yui Kusanagi discovers a magical sword that transports her to a different world where she meets the Greek god Zeus. Zeus is concerned about the weakening bond between humans and the gods, which he fears will bring about future disaster. He has therefore created a school where young gods go to learn the meaning of love. He asks Yui to attend to the school and teach these gods about the workings of the human heart.
Over the course of the series, Yui has encounters with eight gods that come from the Greek pantheon (Apollo, Hades, Dionysus), Norse mythology (Balder, Loki, Thor), and two Japanese divinities, Tsukito Totsuka and Takeru Totsuka, while the Egyptian god Thoth oversees their education. Yui spends various episodes “winning over” each of these gods by going through challenging experiences with them that allow them to bond. Zeus decrees that these gods cannot leave the school (or the world) until they graduate and their powers are shackled by special jewelry until that time.
One interesting storyline that is developed in Episode 9 involves Yui becoming aware of Apollo’s past love affair with Cassandra through a series of dreams she has. Cassandra possesses Yui’s body and appears to Apollo, which provides him with closure over the tragic outcome of their relationship. In the end of the series, after Balder commits suicide and attempts to destroy the universe, the gods band together to save one another and to return Yui to her own world. Each thanks her for the education she has provided them and Apollo confesses his love to her.
