Synopsis
Coming from a distinguished lineage of mages, Ayaka Sajou is widely anticipated to take part in the Holy Grail War. However, following the deaths of her father and older sister in the previous conflict, she has become withdrawn and reluctant to engage in the events that claimed her family. Before long, she finds herself in mortal peril when attacked by a knight, leading her to summon her own Servant, Saber. With Saber's protection, Ayaka is forced into the role of an official participant in a war she desperately wished to avoid.
