Fate/Stay Night: Réalta Nua

Storyline

In the bustling city of Fuyuki, a secret battle rages in the shadows.
The Holy Grail War, a brutal battle royale, pits seven mages, known as Masters, against each other. Each Master summons a formidable warrior from various eras as their Servant, all vying for the ultimate prize: the Holy Grail, a wish-granting artifact.

Emiya Shirou, an ordinary high school student driven by an unwavering sense of justice, finds himself unwillingly pulled into this deadly conflict. One evening, Shirou witnesses a fierce battle between Servants. The clang of steel and the crackle of magic fill the air as they clash. Mortally wounded in the chaos, Shirou is saved by the enigmatic Tohsaka Rin and her Servant Archer. In a desperate attempt to protect himself, Shirou accidentally summons his own Servant, Saber—a noble and beautiful knight with a mysterious past.

As Shirou and Saber navigate the dangerous Holy Grail War, they form alliances and face numerous adversaries, each with their own ambitions and secrets. The bond between Master and Servant deepens as they confront perilous challenges and uncover hidden truths.
