Ashiya Douman

Ashiya Douman is an Alter Ego-class Servant in Fate/Grand Order based on the legendary onmyoji and rival of Abe-no-Seimei. As Limbo, he serves the Alien God and helps create or destabilize several Lostbelt-related incidents.

Ashiya Douman as Alter Ego Limbo

Flamboyant, malicious, and fascinated by human corruption, Douman treats suffering as entertainment while presenting himself with exaggerated courtesy. His schemes are driven by envy, pride, and a desire to surpass Seimei.

Curses, Seimei, and self-destructive ambition

He uses curses, shikigami, onmyodo, and composite divine power incorporated into his Saint Graph. His confrontation with Chaldea in Heian-kyo exposes the limits of his imitation and ambition, while his summonable form remains dangerous even when nominally cooperating with the Master.
