Taiga's grandfather, Raiga Fujimura, is the family head of a yakuza group that operates in Fuyuki City. Her father was adopted into the family as a son-in-law. Like Shirou, she attended Homurahara Academy for her education and is from the same graduating class as Reikan Ryuudou, the older brother of Shirou's friend Issei, and Otoko Hotaruzuka, Shirou's employer.
Taiga was idolized as the star of the kendo club, and was soon known as the "Tiger of Fuyuki" due to her prowess; if not for the tiger strap on her shinai, which was considered bad manners, resulting in her disqualification from official tournaments, it is thought that her name would have become famous across all Japan.
While in school, Taiga got to know Kiritsugu Emiya due to Raiga's friendship with him. Since then, she has been frequently visiting the Emiya residence ever since Kiritsugu moved in. The two eventually became friends, and Taiga would often babysit Shirou when he was younger in Kiritsugu's absence. She had Kiritsugu as her private tutor, but he would only speak to her in English. After Kiritsugu died, Taiga became Shirou's permanent legal guardian and has been living with him for several years.
She became an English teacher at Homurahara Academy and the supervising teacher for the Archery Dojo.
Taiga is a twenty-four-year-old woman with short light brown hair and eyes. She wears a green dress with a yellow and black stripe shirt and white shoes. Her three measurements are unknown but it is said that she is less than Rider but greater than Saber.
In Heaven's Feel true end, everybody else has grown up and m*tu*ed, but Taiga is the same as ever. It seems like she has not aged a day since twenty.
