Mysterious Heroine X

Mysterious Heroine X, Class Name Assassin, is an Assassin-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order. Assassin's appearance is said to be of a young woman with "rough and sporty garments unseemly for Servants." Her blue muffler is a symbol of courage, and her cap is used to hide her identity and ahoge, although it sticks out of the cap. Although Assassin displays a "carnage mode" wagering her single holy sword on nothing but defeating all present Sabers. Mystery Heroine X's wish for the Holy Grail is the destruction of all other sabers. Or at least for them to change their class name to Attacker or Swordsman or something.
