Rin Tohsaka

Rin Tohsaka, a seemingly aloof student idol at Shirou's school, hides a secret: she's a powerful Magus and Master in the Fifth Holy Grail War. Standing at 124 cm (Fate/Zero) or 159 cm (Fate/stay night), Rin prefers solitude, often found on the rooftop away from her peers. Her father, Tokiomi Tohsaka, trained her in magecraft, instilling a strong sense of duty. After his death, she trains to perfect her sorcery with Kirei Kotomine's guidance while secretly aiming for admiration and avoiding scrutiny, despite her competitive nature and tomboyish personality. Rin summons Archer as her Servant initially, with Saber as her original choice.
