SeaBed is a mystical visual novel told from the perspective of three separate characters: Mizuno Sachiko, a designer suffering from hallucinations; Narasaki Hibiki, Sachiko’s friend and a psychiatrist who studies the workings of human memory; Takako, Sachiko’s former lover, who is rapidly forgetting her past, including how and why they became separated from each other, although they were together since childhood.
All three live in different worlds, but strive for the same goal. To separate truth from illusion. To understand their own lives.
