Issei Ryuudou (柳洞 一成, Ryūdō Issei?) is the Student Body President of Homurahara Gakuen.



His father is the head priest of Ryuudou Temple, and his brother Reikan Ryuudou was a classmate of Taiga Fujimura and Otoko Hotaruzuka.

He first became acquainted with Shirou Emiya two years prior the events of Fate/stay night and soon became his friend.[2]

He is a student in Homurahara Academy and he travels two hours on foot every single day to attend school.[2] He is in Class 2-C, and the student council president.



He has a straight-laced and serious personality. As the youngest child of Ryuudou Temple, it seems he has his heart set on one day becoming a Buddhist monk. Though, he will be the first to tell you that his ability to sense the supernatural is weak. He looked up to Souichirou Kuzuki as a mentor, and on holidays they would often perform paired kata together. If he had not gone into the student council, it's a safe bet that he would have enrolled in the karate club instead.[2]

Issei is a friend of Shirou, and his favorite dishes are the lunches that Shirou makes.[2] Issei often asks Shirou to fix broken equipment for the Student Body to try and save money on the school's bill. Issei and Shirou often have lunch together in the Student Body's office where they talk about what ever comes to mind.[3]

He dislikes Rin Tohsaka, who served as his student council Vice President in Junior High for four years, a period after which they decided they could no longer get along. His distrust toward women probably stems from the behind-the-scenes feud they have been engaged in for the past two years. However, as much as it pains him to admit it he still recognizes Rin as a human being.[2]

Though he seems to have a fear of women, he instantly takes a liking to Saber, explaining that "even he can tell" that Saber was a good person.


Fate/stay nightEdit

Issei in the Fate/stay night [Unlimited Blade Works] anime.

He was first seen in the prologue when Rin encounters him when Shirou was repairing an equipment with his Magecraft. Issei becomes suspicious of Rin arriving to school early when she is not involved in any club.

Rin suspected Issei to be a Master of Caster as he resides in Ryuudou temple. Shirou decided to investigate this matter, he strips Issei and search for any signs of Command spell. Issei informs Shirou and Rin that Souichirou has been living in the temple and brought a fiancée. Issei unknowingly tells Shirou that Caster is at the Temple.

In the Fate route, He comes over to the Emiya residence to check on Shirou, who's pretending to be sick from school, and to return the bicycle he left at the temple when he went to retrieve Saber from there. After Shirou apologizes for leaving his bike there, Issei notices Saber standing behind Shirou. Saber introduces herself as distant relative of Shirou, saying that she was treated kindly by Kiritsugu when he came to her country and she is now staying at the Emiya residence thanks to relation with him. Accepting her story, Issei believes that Shirou being sick is just a ruse to show Saber around Fuyuki, then he asks for some tea as a token of appreciation for bringing Shirou's bike back to him. Joined by Saber, Shirou and Issei talk about school as they all have tea, and afterwards, as he leaves the house, Issei is told by Shirou that he'll be skipping school for the week to be with Saber. Accepting his reasons, Issei comments that Shirou should be just fine if he's with Saber, having taking an instant liking to her as he can tell that she's a good person. He is then told Shirou that she's a little anti-social as she hasn't laughed yet and always looks troubled even while they talking and laughing about Taiga. Issei however refutes this by saying that Saber was smilling quite a lot, but Shirou doesn't believe him as he can't imagine her bursting out in laughter. But, Issei corrects him by saying that she was smiling when she saw him smile, though this only confuses Shirou, who asks if Saber is making fun of him. Issei merely laughs off Shirou's question, saying that he interprets things oddly and should torment himself on that subject as he leaves. Several days later, when Kirei Kotomine activated the Grail at Ryuudou Temple, Issei and the monks were passed out.[4]

In Ufotable anime adaptation of Unlimited Blade Works scenario, when Shirou, Saber and Lancer were on their way to the Einzbern castle to confront Archer to rescue Rin. Issei, Reikan Ryuudou and the other fifty-one residents of Ryuudou Temple were attacked by Gilgamesh who consumes their mana to strengthen himself after his battle against Berserker and Illya. They were left unconscious and to be taken to hospital.
