Aoi Tohsaka

Formerly known as Aoi Zenjou, she is the childhood friend of Kariya Matou. She is a descendant of the Zenjou family, which had been a family that specialized in maximizing the magical pedigree of their partners, though the Zenjou have since become a family of ordinary people and Aoi herself has no magical circuits. She became the wife of Tokiomi, adopting his surname, and gave birth to two daughters, Rin and Sakura, who both possessed great inherent potential as mages. She accepted Tokiomi's proposal with full knowledge of what it meant to marry a mage. While Kariya loved her as well, he peacefully gave up pursuing her affections because she seemed happy accepting Tokiomi's proposal. It is implied that Aoi and Kariya remained in touch, given that her daughters, especially Sakura, were fond of Kariya's company. Tokiomi's sudden decision to give Sakura away to Zouken Matou comes as a shock to Aoi, though she does not openly oppose his decision. She leaves at the beginning of the Holy Grail War with Rin to live at her parents' home for the duration of the conflict. During the Holy Grail War, Aoi is forced to return to Fuyuki City to look for Rin, who had run away to find her friend Kotone, who earlier had been kidnapped by Caster. Later on, Kariya gives Rin back to Aoi after he finds her, which is also how Aoi finds out about his condition and his resolve to kill Tokiomi. On the final day of the war, Aoi finds her husband dead, with Kariya present in the room, however, being unaware that Kirei was responsible for Tokiomi's death and that Kariya had arrived to confront Tokiomi only after the man was dead. In her grief, she blames Kariya and the Matou family for taking away both Sakura and her husband and claims that Kariya never loved anyone. With both his resolve and heart crushed, he violently strangles Aoi.
