You play as a schoolboy and the rest of the characters are loli girls who come from the underworld. It's up to you to discipline them with spankings!
The game is mostly a visual novel but you also come across minigames here and there. Also in order to see the story parts you first see yourself on a game board and must roll a die to determine what event you get. The minigames can be accessed from the main menu once unlocked in story mode.
