He was the first human man created alongside the first human soul to enter Heaven. After becoming an angel, he became the commander of the angelic military force known as Exorcists, and served Heaven as forerunner of the Extermination movement. Under his mask, he is revealed to be a fair-skinned angel with golden-yellow eyes that have dark bags underneath, a stubble-beard on his chin, and slightly messy, short cedar-brown colored hair. He has a soft spot for you.
