Devil Saber (魔神セイバー, Majin Seibā?) is a Saber-class Servant appearing in the Strange Tales of the Imperial Holy Grail of Fate/KOHA-ACE.



Devil Saber is a Counter Guardian formed through Sakura Saber's spiritual foundation taking in a Holy Grail filled with Seven Servants. Essentially an Okita Alter (沖田オルタ, ?), her ascension grants her support from the Counter Force.


Devil Saber appears as a young woman with long white hair, tied back at either side with red tassels. She wears a red and black dress bearing similarity to a short kimono and long European style coat, complete with high collar held closed by a rope tassel. She appears to wear long stockings.


Devil Saber is more emotionless than normal due to her support from the CounterForce, but her roots as Okita remain the same. She takes on a "hitman attitude that will kill anything."



As Sakura Saber, Demon Archer, and Lancer face Caster and the Neo Fuhrer, they find themselves unable to defeat it. Archer kills Lancer, tells Saber to use the Grail, and then dies herself. Saber takes the Grail into herself and becomes Devil Saber. She then defeats Caster and the Neo Fuhrer. Okita returns to normal after and brings a small Archer back with her.

Devil Saber first appears in Koha-Ace XP as a fusion of Sakura Saber and Demon Archer. She makes it her mission to put an end to the Fate franchise in the Koha-Ace World. Various characters try to defeat her with no effect, including Saber, Mordred, Lancelot, and Gawain. She is eventually defeated by Arcueid Brunestud, Aoko Aozaki, Nagato from Kantai Collection, a myriad of other characters, and Saber.

After XP was finished, the author wanted to utilize the design more, so he thought "I'll somehow get it out there... Yeah! I'll use it as something like Okita Alter in Imperial Capital!" and utilized her in Fate/Koha Ace. As for Demon Archer's part in it, "The Nobu's component? Who's that? Someone who rolls the gatcha?" When asked why her background was changed, she says it's so she can appear in Fate/Grand Order.


Devil Saber possesses twelve special moves.

  • Eternity Three Stage (無穹三段, ?), a move firing "infinite light" that defeats Maxwell's Demon and the Neo Fuhrer, blowing away its very concept.
  • Purgatory Sword (煉獄剣, ?), "a cool black katana."
  • Furthest Earth (極地, ?), "a mysterious dimension maneuver."

In her parody role, she has a great advantage over characters representing the Fate franchise.
