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.
Soon, it was a mining city! With treasure 
stacked high as skyscrapers for the taking!
بسرعة تحولت إلى مدينة تعدين! كِناز مخزون يرتفع
!عاليًا مثل ناطحات السحاب، أصبح متاحًا للجميع
Alsbald entstand eine Minenstadt!
Y se creó una mina en la ciudad,
cuyos sueños crecieron hasta el cielo.
Y establecieron una mina en la ciudad,
cuyos sueños se elevaron hasta el cielo.
Une ville qui sort de terre, une !
Hinode divenne una città mineraria!
Una pila di tesori da arraffare!
Aí foi criada uma mina na cidade,
cujos sonhos cresceram até o céu.
Шахтёрский город вырос как на дрожжах!
