Odd Prison and Lust Underground Labyrinth

An action-adventure escape game set in a mysterious prison complex. You play as Nana, a girl imprisoned on false charges, who must navigate through dim prison corridors and vast underground areas using only a flashlight to find her way out. Her younger brother Shota can be summoned during visits, and players can switch between the two characters to solve puzzles and overcome obstacles from inside and outside the prison. The prison is inhabited not only by guards and inmates but also by supernatural entities. Gameplay combines stealth, platforming, combat, and exploration; you can strengthen character stats through various in-game activities, find hidden rooms and treasures, and upgrade equipment. Your choices throughout the game lead to branching endings, determining whether you escape successfully or encounter an unexpected fate.
