Consumed By

 * Kuusetsu

General
Koko has a very feisty and lively personality and is always eager for a fight when the opportunity presents itself. She also has a strong camaraderie with her fellow Humanoid Shuuki, whom she sees as "sisters", and will willfully put herself at risk for their sake. As a Humanoid Shuuki, she has a temper and violent streak as she wishes to exact brutal vengeance on the Onmyou Agency who experimented on her and the other Humanoid Shuuki.

Regarding Scenario
Koko is rendered unconscious prior to being eaten by Kuusetsu and remains unconscious as she is eaten. It is unknown what state Koko's mind is in after being absorbed into Kuusetsu's body, but she presumably is still unconscious and oblivious to her situation. Thus, she has no awareness and no reaction to the fact that she has been devoured.

Background
Koko was once an ordinary woman who, after being transported to the world of Mato, consumed a mystical peach that gives special abilities to women. However, the peach had an unusual effect on her and turned her into a human-demon hybrid. Afterwards, she joined a society of other human-demon hybrids seeking to turn themselves back to normal.

While helping her ally, Aoba, retrieve her brother, Yuuki, Koko and her comrades did battle with the Anti-Demon Corps who wished to rescue Yuuki. However, their battle was interrupted by the arrival of the Thunder Gods who wanted to abduct the human-demon hybrids for their strong life force. Weakened from their battle with the Anti-Demon Corps, Koko and her comrade Naon were knocked unconscious and abducted by the Thunder Gods.

Mato Seihei no Slave, Manga - Chapter 43
After being taken to the Thunder Gods' lair, Koko and Naon's unconscious bodies were presented to the egg-like God Kuusetsu. After being briefly examined, Naon was devoured by Kuusetsu with Koko following soon after. Koko and Naon were then absorbed into Kuusetsu's body, becoming living batteries for it.

Afterwards, Kuusetsu took on a female form, inheriting Koko and Naon's appearance and personalities, as well as their special abilities.

Fate
To date, Koko remains trapped inside of Kuusetsu's body, alive, but totally incapacitated.
