Yet another version of Artoria Pendragon, this time summoned as the Assassin Class. Wears a scarf, blue track jacket, shorts, and a baseball cap that somehow fails to conceal Artoria's iconic ahoge.
She appears in the Type-Moon April Fools joke Rojiura Satsuki: Chapter Heroine Sanctuary, Fate/Grand Order and Fate/EXTELLA.
Her goal is to rid the universe of the ever growing Artorias and their ilk as she considers them a plague upon the universe and once they are gone she shall be the one and only Artoria. Although primarily focused on her mission to exterminate all Artorias, she has opened her heart to Saber Lily.
Consequently, Artoria wears Mysterious Heroine X's outfit as an alternate costume in Fate/EXTELLA.
Wields the mysterious magical sword, the Himitsucalibur. Its capabilities and powers are a secret.
