Kuramerukagari

In the busy day-to-day life of those in the ever changing coal mine town nicknamed the "Miniature Garden," the smell of iron and dust clouds dance. Among the town's inhabitants are Kagari, a cartographer, and her childhood friend Yuuya, who dreams of freeing himself from the Miniature Garden. Though they spend their fleeting days tenaciously, their everyday lives are transformed with the frequent occurrences of suspicious cave-ins...?! Under the town's swaying billows, the young girl and boy faintly mature into adults. --- Note: The original anime film this was based on has released alongside the movie Kurayukaba, which shares the same universe.
