Key says that Dr. Mima brought her into this world, that he is her &quot;Creator&quot;. But she also refers to him as her &quot;Grandfather&quot;. He is a pioneer in robotics, but he couldn&#039;t develope a robot that would move from his own will, untill he met Tomiko (Key&#039;s grandmother) and her Geist in Mamio Valley... Their daughter Toyoko provides him with a liquid manifestation of her and her mother&#039;s supernatural powers,  which he uses as a &quot;gasoline&quot; for his dolls/robots. Toyoko didn&#039;t want the same fate for her daughter Tokiko, so Dr. Mima fulfilled his daughter&#039;s will of supressing all supernatural powers in Tokiko by hiding all the extracted gel inside her. Unfurtunately this act also supressed her human conciousness. Therefore Key believed she&#039;s another robot of Dr. Mimas&#039;.

Her classmates at school called her Key, as in the "key" to a strange mystery. Key's "grandfather" was a kindly old scientist wanting to use his skill in robotics to create peace and love in the world. But when that kindly old scientist passed away, poor Key was left behind, lacking even the ability to smile. 

There still is hope, however a message left behind for Key suggests a fantastic possibility. Could it really be possible for Key to become a real, live human, if she can only win the love of 30,000 people? A dark, haunting tale of cybernetic sci-fi dreams, spiritual visions, and the turbulent world of Japanese pop music. (Source: Discotek Media)
