Chiyoko
Choyoko was a seemingly human girl of Japanese descent.
Biography
Chiyoko was first seen in an alliance with Axos, who had come to 21st century Tokyo to set up a fake company, which they called the Rising Sun Corporation. One of the corporation's "products" was a drink called "Goruda". Goruda was advertised as a brain tonic, but it would actually transform those who consumed it repeatedly into Axons. In its public face of "Mr. Kin", Axos passed off Chiyoko as 'his' ward and advisor.
When Axos encountered resistance from the Doctor and his allies, Chiyoko betrayed it, freeing the Doctor's companion, Amy Pond, and Major Harada of UNIT. When the Doctor defeated Axos, the dying gestalt claimed that Chiyoko had promised it Earth. Chiyoko replied by saying the deception was necessary "for a new life to begin." (DWM: The Golden Ones)
Chiyoko then somehow managed to travel to Paris, France, 1858, where she watched the Doctor and Amy depart. (DWM: The Screams of Death)
