A Heroic Spirit in Fate/Grand Order. The Witch of Dun Scaith, she can be summoned under the Lancer class normally, and was the free Servant given during the 2016 Summer event under the Assassin designation. She was the teacher of the Lancer from Fate/Stay Night.
She has long purple hair and red eyes, and wears a purple bodysuit. Like her student, she wields the spear Gae Bolg, and dual-wields them for her Noble Phantasm, the "Gae Bolg Alternative". Her summer incarnation has her wear a bikini.
