Etsuko’s father is the weatherman for the local Channel 8 news in Kochi, Japan, where meteorologists not only forecast the weather, they also provide warnings of possible attacks by daikaiju (giant monsters). While daikaiju warnings are frequently issued in Tokyo and other northern prefectures for the likes of Godzilla, Rodan, and Kubadon, attacks in southern Japan are rare. Still, Etsuko is concerned about the weekend weather because she’s been invited to the birthday party of the most popular girl at school. The last thing Etsuko wants is for a thunderstorm or a Gigalar attack to ruin the party along with her chances at improving her social standing. Her father has promised Etsuko blue skies for the weekend, with less than a five percent chance of daikaiju. But much like forecasting the weather, predicting daikaiju patterns isn’t an exact science. And when those blue skies turn gray and the daikaiju siren blares, the most popular girl in school will blame the local weatherman’s daughter for ruining her birthday, leaving Etsuko with no choice but to save face.
