Alter Ego-class Servant seen in Fate/Grand Order, first introduced in the Shimousa arc as Caster of Limbo. Ashiya Douman is best known as the onmyouji rival of Abe no Seimei. He is one of the Foreign Disciples helping facilitating the advent of the Alien God.
As an Alter Ego, his component spirits are Itzpapalotl, Chernobog, and Akimitsu-dono. Perhaps due to Itzpapalotl being a female goddess, Douman's gender is listed as unknown in official material.
