Tokiko Mima 巳真兎季子

Mima Tokiko, commonly referred to as Key, is the granddaughter of Mima Murao and Mima Tomiko. She appears as a somewhat autistic child throughout the majority of the series. She is looking for 30, 000 friends to restore her humanity.

Key's presence is disruptive to PPOR robots. This, and the fact that Key is capable of producing an extremely large amount of quality gel, makes her a target for Ajo and his henchmen.!~
