Plot Concept: The film centers on third-year middle school student Masamune, who lives in a town where time has stopped because a sudden explosion at a steelworks factory has sealed off all exits to the town. In order to hopefully one day return to normal, the residents of the town are forbidden from changing, and they live out their gloomy everyday lives. Masamune’s enigmatic classmate Atsumi leads him one day to the fifth blast furnace of the steelworks factory, and there they meet a girl who is wild like a wolf and who cannot talk. The meeting of Masamune and these two girls upsets the balance of the world. The unstoppable “love impulse” of the boys and girls who are tired of their everyday lives begins to destroy the world.
