Rin Tohsaka

Rin was brought up as the successor to her family's magecraft and was instructed by her father to prioritize magecraft over her own interests. Ten years ago, Tokiomi Tohsaka was selected as a Master in the 4th Holy Grail War, and Rin was entrusted to take care of the Tohsaka estate until his return. Her mother, Aoi Tohsaka, was left in a debilitated state from the war, so her care was left to her guardian, Kirei Kotomine, to whom she deeply disliked. After her father was killed, Rin would continue to improve her sorcery with some guidance from Kirei Kotomine, even if she hates him. To divert attention from her private life, Rin has diligently strived to earn the admiration of her peers, even though she is secretly stingy, tomboyish, and a perfectionist. The rights to the Tohsaka lands were inherited by Aoi after Tokiomi's death and subsequently inherited by Rin after Aoi's death. Kirei managed them as Rin's guardian, and because of his foolhardy and coarse management, the majority of profitable properties ended up in the hands of others. It is possible that he believed the wealth was bad for her upbringing due to following the principles of humility and poverty. Although Rin resents the sacrifices she has endured for the sake of tradition, she is fiercely competitive and eager to prove herself as a skilled and capable magus. She was immensely disappointed at summoning Archer and ended up in a quarrel with him; however, the duo soon reconciled, set aside their differences, and quickly got along. Before the 4th Grail War, Rin younger sister Sakura was given up for adoption by the Motou family. Due to Mage law only allowing one child to be given a family crest, Rin father favored her over Sakura and thought it would be perfect rather than forcing his daughters to go against each other. Rin tried to convince herself that Sakura would live a better life. However, Sakura would only suffer from her new abusive step-brother, Shinji Motou.
