Kuramerukagari

In the coal mining town crowded with small-scale miners, known as the "Hakoniwa", there is a girl named Kagari who runs a map shop, and her childhood friend Yuya, who dreams of breaking free from the "Hakoniwa" and the ever-changing labyrinth-like tow. Lately, suspicious "sinkhole accidents" occurring frequently in the town begin to encroach on their daily lives. Will Kagari be able to overcome this situation and determine the fate of the town? Beyond the challenges, the girl will grow up a bit today.
