List of minor characters in the Fate series

Archetype Saber
Saber (セーバー), romanized as "Saver" in Character Material, is the archetype version of Saber that was to be used in the original Fate/stay night novel that was penned and left uncompleted. It was decided during the development of the visual novel that Saber's master, Sajyou Ayaka, was not an ideal protagonist for the target audience, so both Saber and Sajyou were redesigned and had their genders swapped to make them more appealing. 

Fujimura Raiga
Fujimura Raiga (藤村雷画) is the Oyabun (組長 family head) of a yakuza group operating in Fuyuki City, and is the grandfather of Fujimura Taiga. He was an old friend of Emiya Kiritsugu, and as a favor, manages Kiritsugu's estate after his death in place of Emiya Shirou.

Himuro Kane
Himuro Kane (氷室 鐘) is a student at Homurabara School. She is a friend of Saegusa Yukika and Makidera Kaede, and a long jumper. She is considerate and intelligent.

Sajyou Ayaka
Sajyou Ayaka (沙条綾杳) is the archetype version of Emiya Shirou detailed in Character Material. She was to be the protagonist of the original Fate/stay night novel that was never finished and the master of the male version of Saber. It was felt that she would not appeal to the target audience of the visual novel, so she was redesigned as Shirou to be more appealing. She appears in Fate/school life as one of the students as Shirou's school.
