Key The Metal Idol
Tokiko Mima, called Key, is a robot. Since she was created by her "grandfather," Dr. Mima, she has lived among humans. Now Dr. Mima is dead, and has left behind a cryptic last message: if Key can somehow get 30,000 people to feel for her, she can become fully human. However, Key's quest may not be so simple—for an ominous plot is being hatched by Dr. Mima's rival, Jinsaku Ajo.
