In the Japanese anime One Piece, there is a prison called “Impel Down” with five levels.
“Impel Down seems to be heavily based on how Hell is described in Dante Alighieri’s Divine Comedy. Both are level-based, ‘inescapable’ prisons with unique forms of punishment per level, and the lower one traverses, the worse the punishments become.” —One Piece Wiki
