Rin Tohsaka (遠坂 凛, Tōsaka Rin?, Romanized as Rin Tousaka in the English version) is the Master of Lancer in Fate/Extra. She is a different person than the Rin Tohsaka that appears in Fate/stay night, but they are relatives part of the same lineage in the Fate/Extra universe. She is an activist that fights against the Harway family, so her reason to participate in the Holy Grail War is to stop Leo.
