This is a story that weaves together people and a town. A coal mining town crowded with small-scale excavators, commonly known as the "Hakoniwa." In this town that changes daily like a labyrinth, there's a girl named Kagari who runs a mapmaking business and a boy named Yuya who dreams of breaking free from the "Hakoniwa." Eventually, the two, along with the unique residents of the town, find themselves confronting a conspiracy that shakes the entire town. The fate of the” Hakoniwa" depends on Kagari's drawings on the map.
Even now, they lurk beneath our feet,
،‫حتى الآن، يتربَّصون تحت أقدامنا
Auch jetzt kriechen sie
durch die Tunnel
Sí, moran en algún lugar bajo tierra
Sí, viven en algún lugar bajo tierra
Mentre parliamo, sono sotto di noi
 a minacciare pace e benessere.
Sim, eles moram em
algum lugar no subsolo
Даже сейчас они копошатся
у нас под ногами!
