The game follows the main character Laegrinna, the devil's daughter who was created from a fragment of his soul. Three thousand years ago, the devil was defeated by twelve warriors known as the Saints where they sealed him using the Holy Verses. After the devil's imprisonment, the Verses were divided into 12 items and given to the Saints and their descendants. In the present, Laegrinna is tasked by her father to find the Holy Verses from the descendants of the Saints so the seal imprisoning her father can be broken. Helping in her mission are Caelea, Veruza and Lilia, daemons and servants of her father.
As a game focused on strategy, the player aims to defeat enemies by luring them into a wide variety of traps. The aim of the game is to prevent the enemy from reaching the player, exclusively using traps. Players can choose to utilise a variety of different traps, including rolling boulders, electrocution, fire, spring boards, spiked walls, human cannons, falling bathtubs, banana peels, an iron maiden, and locomotives. Proper timing of traps is an important aspect of the gameplay, as the player is also able to fall victim to their own traps.
