Sir Gareth, Class Name Lancer, is a Lancer-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order. Gareth highly reveres Lancelot. She seems to normally have a sunny, friendly disposition, and as a result she does not deal well with the stress of the slaughter performed under the Lion King during the Camelot singularity of Fate Grand Order, only wishing to be punished. She had "mummy-like bags" under her eyes after helping to defeat the knights who opposed the Lion King, and although she has "lily-white fingers that are more beautiful than anyone's", they become unrecognizably blackened from constant washing after combat. Brave and faithful like a small puppy, a young knight of tragedy. Once she has grown attached to someone, she will never betray no matter what. Even if it means the death of her. She lives as she always has lived. Honoring chivalry, believing in justice and carrying it out. She is proud of the fact she was accepted by the Knight King, and even now she considers being selected as a member of the round table as the greatest honor of her life. She still admires Sir Lancelot. The day everything ended. The day the knight moved to save Queen Guinevere. She would adore him even if her own form hadn’t so much as entered the knight’s eyes. She would adore him even if… he had known her, yet didn’t hesitate to kill her regardless.
