Rin Tōsaka
Rin Tōsaka is a character from the Japanese visual novel and anime series Fate/stay night.
Her birthday is February 4 and her blood type is O. At the time of Fate/Zero, her height is 124 cm, while her weight is 29 kg. Ten years later, she had grown to 159 cm and weighed 47 kg, and her three-sizes are B77/W57/H80.

A model student and idol of Shirō's school, Rin is secretly a sorceress and Master in the Holy Grail War. She is descended from a long line of sorcerers, and though lacking a formal magic education, is extremely powerful in her own right. Her father was killed in the 4th Holy Grail War, and she has trained since his death to succeed him. She is perceptive, resourceful and avidly competitive. Although she tried to summon a Saber-class Servant, she accidentally called Archer instead. Also it is hinted in the anime that she had some kind of feelings towards Shirō, before they teamed up. It was in Episode 2, where she revived him back and was blushing when Archer questioned her for her actions.

The voice acting for Rin is done by Kana Ueda in the Japanese version. Mela Lee is the English voice of Rin.
