Fujimura Taiga

Taiga was leaving her job at Homurahara Academy, she was looking at the night sky, the night sky is beautiful at this time of year because of the clear sky she said in her thoughts, when suddenly she tripped and fell because she was so enthralled looking at the sky.

Taiga's grandfather, Raiga Fujimura, is the family head of a yakuza group operating in Fuyuki City. His father was adopted into the family as a son-in-law. Like Shirou, he attended Homurahara Academy for his education and is in 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 it were not for the tiger strap on her shinai which was considered rude, resulting in her disqualification from official tournaments, it is believed that her name would have become famous throughout Japan.

While at school, Taiga met Kiritsugu Emiya due to Raiga's friendship with him, frequently visiting the Emiya residence ever since Kiritsugu moved away. The two eventually became friends, and Taiga often babysat for Shirou when he was younger in Kiritsugu's absence. She had Kiritsugu as her private tutor, but he only spoke to her in English. After Kiritsugu's death, 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 of the archery dojo.
