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.
Are you crazy? It's dangerous to go 
poking around in a Mushikui Cavity.
.هل جننت؟ من الخطر التفتيش في جوف موشيكوي
Ich glaub’s ja nicht.
Pequeña tontuela,
los hoyos de lombrices son peligrosos.
Serás mentecata…
Los agujeros de lombriz son peligrosos.
Imbécile, va.
Razza di stupida!
Você é besta. Esses túneis
de Mushikui são perigosos.
Совсем крыша поехала?
В Полостях, знаешь ли, опасно!
