Rin Tōsaka (遠坂 凛 Tōsaka Rin, Rin Tohsaka in anime) of Fate/stay night is a model student and idol of Shirō's school.
Rin barely talks to other students in her school and exhibits a desire to be left alone, as exemplified by her tendency to stay on the school's rooftop, away from the rest of the students. She is also secretly a Magus, and a Master in the Fifth Holy Grail War. In the beginning of the anime, she summons Archer for her Servant, although she originally wanted to summon Saber. Rin is reared as the successor to her family's magecraft, instructed by her father, Tokiomi Tōsaka, to prioritize sorcery over her own interests. When she was young, Rin was separated from her sister Sakura, who was given to the Matō for adoption. After her father is killed in the Fourth Holy Grail War, Rin continues to perfect her sorcery with some guidance from her guardian, Kirei Kotomine. Several years later, she and Sakura observed a young Shirō attempting to jump over a high bar for a fitness test, and secretly fell in love with him due to his dogged perseverance. She strives to earn the admiration of her peers to avoid drawing attention to her private life, even though she is secretly stingy, tomboyish, and a slacker. She is perceptive, resourceful and avidly competitive.
Rin is voiced by Kana Ueda (Japanese) and Mela Lee (English).
