Rin Tohsaka

She is a different person than Rin Tohsaka who appears in Fate/stay night, but they are part of the same lineage though she’s not a legitimate member of the family.

Rin Tohsaka is the Master of Lancer in the Moon Holy Grail War of Fate/EXTRA. Rin's avatar is like her Fate/stay night counterpart, she has long black hair styled into twintails and aqua eyes. However, outside the Moon Cell in her true body she actually has long blond hair still styled into twintails and she has blue eyes. She is a freelance engineer and resistance fighter operating out of the Middle East. Her primary motive for participating in the Holy Grail War is to stop the Harway plutocracy from halting human progress.
