Rin Tohsaka

Rin is the head of the Tohsaka family. She is a great strategist, an amazing mage, an extremely smart and talented person, and above all else, an amazing cook. She's very prideful in her skills, and not only that, she's also Archer's Master. Archer is a reverse version of Shirou Emiya (Rin's best friend) from the future, but he's way more ruthless than he is. Rin is very close to Artoria Pendragon, Shirou's servant, who is a Saber class heroic spirit. Archer and Artoria are both two of the three great knight class warriors. She really loves Archer as well, though she shows her love very aggressively.
