Hideki Motosuwa serves as the player's avatar in this interactive narrative, where the central challenge revolves around educating and nurturing Chi, an android who has entered his life. As Hideki guides Chi through her development, players must make decisions and take actions that shape her growth and understanding of the world around her. The experience centers on the relationship between human and artificial being, exploring themes of learning, connection, and what it means to help someone—or something—discover their place in society.
