Yuuki Yuuna and her fellow Hero Club members take a break from their usual duties in this comedy spinoff of Yuuki Yuuna wa Yuusha de Aru, which turns to their everyday lives. Yuuna is a second-year middle schooler in the era of the gods, year 300, and her club's activities normally involve dealing with a mysterious being known as the Vertex. Adapted from Kotamaru's four-panel spinoff manga, the film was screened together with the Washio Sumi no Shou movies.
