ℭreated by an angel and demon in love, he was left at the doorstep of Sister Freya, a nun who worked with the Society of the Adamant Earth. The Society was an organization dedicated to preventing God or the Devil from taking Earth into their own grasp, to keep the Earth free from their influences. To most, such a dangerous being left on their doorstep was a terrible idea on all counts.

For Sister Freya, the baby was a child who had been given to her to cherish.

She held him to no obligations with regards to his identity; he knew that he was female, but to decide who he actually was...that was a challenge, until the age of fifteen, when he asked to be referred to with he/him pronouns. Later, he then decided on his name: Kyrie.

When he was twenty-one, he was given a weapon. At twenty-three, he killed a demon. Half a year after that, an angel. He made a knife from the demon's tail, and a cloak from the angel's wings, further cementing himself as a force to be reckoned with in both Heaven and Hell.
