Yui Kusanagi is your typical average High School girl who loves swords and who has parents that own a shrine. Her parents plan to pass the shrine on to one of her brothers thus giving them a plan for life. Not only that, Yui's friends also have a plan for life, whether it's love or just based on studying for test exams. One faithful day, as she is at her parents shrine, she enters a storehouse and sees a shining sword. As she touches it, she is transported to very beautiful garden made by Zeus, the Greek god who was god of all gods. Upon being transported there, Zeus informs her of the reason she will be useful to him: she is meant to help 9 other gods, who all have problems with humans and love, by showing them the true meaning of love.
