Equuleus Kyoko

Kyoko was the Equuleus Saintia in XX Century.

Childhood
Shoko, Kyoko's sister, was cursed to become the host of Eris, a god that will cause war around the world. Kyoko always was mature, and tried protect Shoko of the dangers. In a night, Atë tried to possessShoko body, and the love of Kyoko and his goal to protect his younger sister, allow Kyoko access the Dark Eden (where was Shoko and Atë, and only the Dryads, Eris and the host can access) and saves Shoko; after all, Milo saves Shoko and Kyoko knew about her course; so, Kyoko followed Milo advice and goes to Graad Foundation to become a saintia, to protect Shoko. Shoko always feels missing of Kyoko. She was sent with Mii, Xiaoling, Erda and Katya to training in another country.

Saintia
In the training, Kyoko met Rigel, that fell in love for her. After the graduation, Kyoko came back to Japan to protect Shoko and Saori (protect Saori is the mission of the saintias). But, Atë attacks again and finds with her again. But, Kyoko doesn't get away, and fights, and because this, Atë defeats Kyoko. After trying possess Shoko, Kyoko saves her again, and receives Eris soul in her place. Because this (Kyoko is the wrong host), Eris need to sleep in the body in a coma, to get total control of Kyoko's body.

Death
Eris waked up before the right time, and try to kill Saori, but, how the process was not completed (because Eris waked up too early), Kyoko could control her body to disturb Eris, and Atë saves her master.

In the Eris sanctuary, Shoko and Saori tries saves Kyoko at the last time, but Eris soul disturbs them; to stop the complete possession, Kyoko holds Eris soul, and merges on it, allowing Milo to kill her body.

Rebirth
Kyoko revives as a evil being, because her soul merged with Eris soul, and become a evil woman.
