Description
Issei Ryūdou holds the position of Student Council President at Homurahara Academy, a role consistent across multiple media portrayals. As the youngest son of Ryuudou Temple's head priest, he has an elder brother named Reikan Ryuudou who attended school with Taiga Fujimura and Otoko Hotaruzuka. Two years before the events of "Fate/stay night," Issei formed a friendship with Shirou Emiya, regularly sharing lunches in the Student Council office and frequently relying on Shirou to repair school equipment to reduce costs.
In "Fate/kaleid liner PRISMA☆ILLYA 2wei Herz!," Issei coordinates logistics for a beach trip at Shirou’s request. Suzuka Kurihara probes his relationship with Shirou, taking notes for creative purposes. Noticing "Edelfelt construction" signage, Issei deduces a building’s connection to Luvia Edelfelt, earning remarks from Rin Tohsaka and Luvia about his observant, sister-in-law-like demeanor. He voices frustration over cleanup duties and incidents involving Rin and Luvia.
When female characters clash over Shirou, Issei intervenes, refusing to release Shirou to "some woman" and insisting only "a man from Ryuudou temple" should care for him. After Shirou calls him a "chicken" under Magical Ruby’s truth serum, Issei is sedated, and Magical Amber erases memories of the event.
Issei harbors longstanding animosity toward Rin Tohsaka from their tenure as Student Council President and Vice President in junior high, fostering mutual distrust and contributing to his general wariness of women, though he begrudgingly acknowledges her humanity. Adaptations vary in depicting this aversion—ranging from paranoia in manga (where he deems Rin a "demon" and vows to protect the school) to disinterest in anime. Despite this, he feels immediate ease around Saber, sensing her inherent goodness, and respects Ayako Mitsuzuri as Shirou’s friend and archery captain.
Raised with Buddhist temple values, Issei embodies seriousness and integrity, though destined for monkhood despite lacking supernatural sensitivity. He deeply respects mentor Souichirou Kuzuki, practicing paired kata with him during holidays. Widely recognized for his leadership, peers view him as an irreplaceable Student Council President, complicating succession plans. He advocates for reforms, including revised club funding and regulatory amendments.
