Taiga Fujimura teaches English at Homurahara Academy and supervises its archery dojo. She acts as legal guardian for Shirou Emiya, living with him since his adoptive father Kiritsugu Emiya died. Her grandfather, Raiga Fujimura, heads the Fujimura Group, a yakuza organization in Fuyuki City, linking her to the local underworld. Despite this connection, she maintains a cheerful, carefree demeanor, frequently visiting the Emiya residence to relax and enjoy meals cooked by Shirou or Sakura Matou. As a student at the same academy, her exceptional kendo skills earned her the nickname "Tiger of Fuyuki." However, attaching a tiger strap to her shinai led to disqualification from official tournaments for bad manners, preventing potential national recognition. She dislikes the "Tiger" nickname, reacting angrily or tearfully when called it, and prefers Shirou's affectionate term "Fuji-nee," viewing him as a younger brother. Her bond with the Emiya family started through Kiritsugu, whom she met during his time in Fuyuki and developed an instant crush on. She visited their home often. Initially clashing with Shirou, their relationship evolved into a sibling-like dynamic. After Kiritsugu's death, she became Shirou's permanent guardian. Kiritsugu privately tutored her exclusively in English, influencing her career path as an English teacher. During the Fourth Holy Grail War, while chasing a thief who stole a wine barrel from her friend Otoko Hotaruzuka's store, she fell from a roof and encountered Waver Velvet and Rider. Rider translated as Taiga recounted her pursuit. Later, rescuing a puppy from a lake demonstrated her belief in others' kindness. This experience, coupled with Waver and Rider's suggestion she guide knowledge-seekers, reinforced her commitment to teaching. Anonymous delivery of high-quality wine barrels to her friend's store followed this encounter. Daily life reveals Taiga's bright yet childish personality, marked by irresponsibility and clumsiness. She distrusts newcomers to Shirou's home, especially Saber, fearing they might "take Shirou away." Unable to cook, she relies on others for meals, often saving breakfast scraps for lunch. Her three measurements are noted as less than Rider's but greater than Saber's. In the *Heaven's Feel* route's True End, she appears unchanged while other characters age, seemingly not aging since her twenties. In the *Heaven's Feel* films, her role is supportive, primarily interacting with Shirou and Sakura at the Emiya household. She expresses concern for Shirou's safety during the Holy Grail War without direct involvement in the conflict. No substantial character development or altered role is reported for her in this adaptation. In spin-offs like *Fate/kaleid liner PRISMA☆ILLYA*, she appears as a teacher at Homurahara Academy Elementary School. She retains her cheerful personality but displays a formidable temper when angered. Her role here introduces no significant new background or development beyond established traits.
