In the woods not far from the city lies a school called the Miniature Garden. In keeping with the schools name, an original Miniature Festival is held there every three years. There's a rumor that an unnatural death will befall someone on the night of the festival. This year, as the sun sets, Yasunari and four other students find themselves trapped alone in the school on the night of the festival. Is it just a mistake, or could the rumors be true?
