Jinno Kyoji returns to Kurehito City after several years away, moving in with his free-spirited cousin Saitama Yamiko while his parents work abroad. Familiar faces reappear — Kazuyagi Akane, the strong-willed tomboy he grew up with; her gloomy best friend Namiki Aoi; and graceful, kind-natured classmate Misono Kiika. Life feels almost peaceful again. Then, on his first morning walk to school, he meets a pale girl with violet hair and striking eyes who tells him to remember her name: Yuka. Wherever Yuka goes, a terrifying figure called Gore Screaming Show is never far behind. Their arrival marks the end of Kyoji's peaceful days — and the beginning of something far darker.
