Sacks&Guns!! (TV Series)

TV Series (2021). 12 Episodes. The distant future, long after the Western calendar is no longer used. Humans live shoulder-to-shoulder, cramped in the "Labyrinth," an underground world deep below the surface. There are many colonies where people live in the underground Labyrinth. The place is known for extreme high temperatures, but also for lodes of gold, silver, and other riches. In one of the colonies named Pin-in, a curious nine-year-old girl named Memenpu and her father Gagamba board a two-person work robot and mine for ore. They eke a living as the lowest of lowest "Worker" occupations. One day, Memenpu begs her father Gagamba to set out as Markers — those who chart the innards of the Labyrinth as a spelunker — to search for her mother who left their home. (Source: ANN)
