Nanba is the most formidable prison in the world, designed to hold offenders who are too evasive for standard incarceration.
The four occupants of Cell 13 are especially clever in this regard, having successfully escaped from every other prison. There is Juugo, a lock expert who has spent the most of his life in prison;
Uno, an intuitive gambler; Nico, an otaku whose body reacts weirdly to narcotics; and Rock, a food-obsessed bruiser.
Hajime Sugoroku, the building administrator, has a difficult time preventing the four prisoners from escaping from Nanba because to the constant mischief caused by their everyday antics.
