Kyrie Ushiromiya

Kyrie Ushiromiya's powers and abilities

Kyrie is a member of the Sumadera family, which was a sort of rival to the Ushiromiya family. Kyrie got a job working under Rudolf at his company and started dating him, even when he was already married to Asumu. Kyrie eventually got pregnant and was prepared to give birth on the same day Asumu was to give birth to her own child, however Kyrie suffered a miscarriage. Kyrie then developed extreme jealousy towards Asumu for being able to give birth to Battler, and this envy would last even after Asumu's death. Twilight of the Golden Witch reveals that Kyrie is actually Battler's biological mother while Asumu had a miscarriage. Rudolf bribed a doctor to switch the results, not wanting it known that he had an illegitimate child.

After Asumu died, Kyrie immediately married Rudolf and abandoned the Sumadera family, leaving her younger sister Kasumi to become the head. Kyrie gave birth to Ange a few years later.

The Twilight manga suggests that Kyrie and Rudolf were the true culprits behind the Rokkenjima Mass Murders, with Rudolf and Kyrie being killed by Eva after the event. After the events of 1986, Ange is adopted by Eva.
