Key the Metal Idol

Key believes she is a robot, and her dying grandfather leaves her an extraordinary instruction: the affection of 30,000 people can make her human. She travels to Tokyo, where becoming a singer seems a possible way to reach so many hearts.

Her old friend Sakura offers a home and support, but Key's strange abilities attract far less benevolent attention. Behind performances, machines, and promises of fame lies a history that may explain both what she is and why others want to control her.
