Thoth suddenly announces that tomorrow is summer vacation, as per Zeus' decision to change the season. Although several gods play truant, the others manage to arouse their interest in school by starting a seaside school, in hopes of showing them the fun side of school. The changing of the season again -- this time to autumn -- forces them to warm up in a nearby house instead. As Apollon tries to make seaside school fun even in autumn, Thor and Loki decide to leave, claiming that he has no right to order them around because he is a student as well. This prompts Yui to give him the title of 'Student Council President'. Apollon, pleased, finds the way to make seaside school fun by ending the night with fireworks purchased from the school store, which sells everything and anything.
