The Onmyouji (陰陽師 Sorcerer) in modern terms are Human mediums, having the ability to detect the existence of all types of spiritual beings. They are a segmented part of humanity and the spiritually aware who have deveoped ways to deal with Hollows. Unlike their, technically "brethren" the Quincy, the Onmyouji are not as aggressive nor do they have bad relations with the Shinigami. Originally, they started as a religious movement around the 7th century that quickly grew into one of the largest forces in the World of the Living. Their most prominent rise to fame was during the Heian period in Japan when the Imperial Court granted them official government responsibilities and influence over its people.
