Prequel to Fate/Prototype. Tokyo, 1991. Seven mages gather to summon seven heroes from history, myth, and legend to do battle in a great ritual. The last ones standing will obtain the Holy Grail—a font of limitless power said to be able to grant any wish. One such Master is Manaka Sajou, a young maiden with immense expectations placed on her. But when she lays eyes on the one she summons, what she sees is not her Servant but the fairy tale prince of her dreams! (Source: Yen Press)

Manaka Sajyou, an existence connected to Akasha, is unable to experience phenomena like change and surprise, so she wishes to attempt to "dream." She sends her consciousness through the backside of the World, beyond the end of the world, and into different time and space. She ends up in a labyrinth, hosting a variant Holy Grail War, featuring four Servants and Masters attempting to reach the bottom. Manaka possesses the body of a Master who had summoned a female King Arthur. Saber interacts with Manaka, while Manaka and the original Master see each other when looking into a mirror.
