Fate/Extra: Last Encore

Tsukimihara Academy is a simulated high school created by Moon Cell's computer, designed to host the Holy Grail War. 128 candidates, who have been projected from Earth as Earth-projected souls, will be chosen to participate in the main tournament. These candidates will be granted a Servant, a powerful ally in the war.

Hakuno Kishinami, one of the candidates, finds himself in a desperate fight for survival after being awakened in his own blood. He discovers a crimson blade, which leads to the summoning of Saber, his Servant. With Saber by his side, Hakuno sets out to uncover the secrets of Moon Cell and his own troubled past, ultimately aiming to reach the Angelica Cage, the central core of the artificial world.
