A dying professor leaves a message for his grandaughter Tokiko \'Key\' Mima. She is an android, but she is dying, and her battery is irreplaceable. If however, she can make 30,000 friends, their love will rejuvenate her, and turn her into real girl. Is she a dying robot? Most of her friends think she is just a traumatized, abused little girl. And who are these interested parties pursuing her? Is she really an android who holds a powerful force within her? Or is she just a troubled little girl?
