The Sudden Roommate Cousin Becomes a VTuber

A story about a shy younger cousin named Shiori who moves into the protagonist's house. To pay living expenses, she begins streaming as a VTuber, discovering confidence behind the camera that she lacks in person. Her casual, intimate chat streams slowly gain popularity as a "homebody VTuber," but her demeanor differs between her online persona and her behavior at home with the protagonist. As her streams succeed and she gains validation, her trust and emotional dependence on the protagonist deepens. The game explores how their relationship evolves through her streaming activities and shared living space, with branching scenarios shaped by player choices regarding affection versus dependence. Gameplay includes mini-games like comment moderation during streams and thumbnail creation, with multiple erotic scenes featuring both Live2D and sprite-based animations.
