Rin Tohsaka (Fate/Extra)

Tohsaka Rin is an alternate version from her Fate/stay night counterpart that appears in Fate/Extra. She is the Master of Lancer.

While not the same Rin from Fate/stay night, she is part of the same lineage of Magus. She's an activist that fights against the Harvey family, so her reason to participate in the Holy Grail War is to stop Leo.
