sword_of_st._catherine_(fate)
The sword wielded by Jeanne d'Arc (Ruler) (fate). It belonged to St. Catherine that Jeanne never used while alive. She can use it to activate the suicide-type Noble Phantasm La Pucelle: The Crimson Holy Maiden, which can destroy anything in exchange for her own death. Jeanne d'Arc Alter (Avenger) (fate) uses a blackened version of the sword.
