This narrative weaves together the lives of its citizens and a coal‑mining town saturated with small‑scale diggers, commonly called the 'Hakoniwa.' The settlement morphs each day like a shifting maze, and within it a girl named Kagari runs a map‑making shop while a boy named Yuya longs to break free from the confines of the 'Hakoniwa.' Together with its eccentric inhabitants, they confront a hidden conspiracy that rattles the entire community. The town"s future rests upon Kagari's detailed drawings on her maps for the next generation in the heart.
