Memory wakes up inside the data of a video game, fully conscious. She walks through a fictional version of Tokyo, gathering clues about the location of someone she is searching for. Along the way, she meets the city's unusual residents: her best friend Messiah, a classmate who works at the arcade named Cult, and a mysterious elementary school student who is always alone, called Lime. The choices Memory makes shape the direction the story takes. Beautiful visuals, memorable music, and unexpected horror that builds toward something neither Memory nor the player fully anticipates.
