Norika's Case

Norika's Case is a 3D adult dating simulation and detective mystery game. You play as a detective from a small provincial town trying to solve the five-year disappearance of your sister, Norika. The investigation intensifies when your brother dies and you receive unexpected clues, forcing you out of despair and back into action. The game combines narrative-driven detective work with relationship-building mechanics—your choices throughout the story shape the plot and determine which of multiple endings you reach. Along the investigative path, you'll develop romantic and sexual relationships with various women on an island setting, with branching story routes tied to each character. The game balances serious mystery elements with adult-oriented romantic content, including explicit scenes and animations.
