ibuki_douji_(fate)

Saber-class Servant introduced in Fate/Grand Order's Heian-kyou (fate/grand order) singularity. Known as Yamata no Orochi's daughter, and the progenitor of Shuten Douji (fate). In Fate, Ibuki and Shuten exist as dual personas, with the two taking turns as to who manifests; when both in Chaldea simultaneously, they act as if they're incapable of seeing the other.
