Ten years after the Fourth Holy Grail War, a devastating clash between Masters and Servants, another war erupts. Shirou Emiya, whose father fought in the first battle, was leading a peaceful life with the warmhearted Sakura Matou. But when hidden forces begin to stir, Shirou resolves to fulfill his father’s dying wish, protect Sakura, and fight for the Holy Grail.

In the World before, novice mage Shirou Emiya summoned and bonded with beautiful heroic spirit Saber as they became enmeshed in the battle for supremacy known as the fifth Holy Grail War. Fate, however, is a fickle mistress, and there was more than one way for that story to transpire. Now, in an alternate timeline, the pairing’s destiny becomes more tightly intertwined with that of high school student/secret Mage Rin Tohsaka and her Servant Archer. Even if you think you know what will happen next, prepare to be surprised as new twists await at every turn.

Having failed in their quest for the Holy Grail, the knights of the Round Table return to Camelot, their number reduced to a mere handful. Seeing a rift developing between Lancelot and Mordred, Arthur urges his knights to bury their differences and become friends. However, the king is unaware that Lancelot is having an affair with his queen, Guinevere. Lancelot is torn between his duty to his king and his love for the queen, whilst Mordred is determined to use his infidelity to destroy him.

Arthur fulfills his fate by bringing together the Knights of the Round Table at Camelot and unifying the country. However, this flawed monarch faces greater tests ahead in pursuit of love, the Holy Grail, and his nation's survival.

In Camelot, kingdom of Arthur and Merlin, Lancelot is well known for his courage and honor. But one day he must quit Camelot and the Queen Guinevere's love, leaving the Round Table without protection.

King Arthur, accompanied by his squire, recruits his Knights of the Round Table, including Sir Bedevere the Wise, Sir Lancelot the Brave, Sir Robin the Not-Quite-So-Brave-As-Sir-Lancelot and Sir Galahad the Pure. On the way, Arthur battles the Black Knight who, despite having had all his limbs chopped off, insists he can still fight. They reach Camelot, but Arthur decides not to enter, as "it is a silly place".

Two troubled men face their terrible destinies and events of their past as they join together on a mission to find the Holy Grail and thus to save themselves.

A beautiful young woman sets her sights on an aging millionaire. She seduces him, and moves into his mansion with him. She soon tires of him, though, and after she gets rid of him, she goes after his son.

A young girl is struck and seriously injured by a wealthy society matron's car. The woman brings the girl back to her house. Later, a hardened thief is told by the girl of a goblet, that could be the Holy Grail, which has healing powers and could help her. The thief, touched by her predicament, sets out to steal the goblet and bring it to her.

German composer Richard Wagner wrote Parsifal, which is a three-act opera that tells the story of the title character's quest to save the Knights of the Holy Grail by returning the Holy Spear, healing King Amfortas, and carrying out the sacred ceremony of uncovering the Holy Grail.

In a Holy Grail War, Mages (Masters) and their Heroic Spirits (Servants) fight for the control of the Holy Grail—an omnipotent wish-granting device said to fulfill any desire. Years have passed since the end of the Fifth Holy Grail War in Japan. Now, signs portend the emergence of a new Holy Grail in the western American city of Snowfield. Sure enough, Masters and Servants begin to gather... A missing Servant class... Impossible Servant summonings... A nation shrouded in secrecy... And a city created as a battleground. In the face of such irregularities, the Holy Grail War is twisted and driven into the depth of madness. Let the curtain rise on a masquerade of humans and heroes, made to dance upon the stage of a false Holy Grail.

The battle rages on as Shirou continues to protect Sakura, now consumed by the darkness. He joins forces with Rin to end the Holy Grail War, while Illyasviel, who knows the truth behind it, confronts her fate. Amidst the chaos, Zouken plots to manipulate Sakura for his own desires. The final fight begins.
