Ep 1313. Time of DepartureShirō returns home and reminisces about how Kiritsugu's ideals and the Fuyuki City fire ten years ago inspired him to become a hero of justice. Meanwhile, at Kirei's church, Caster visits a captive Saber, who is resisting her magical torture. She is then confronted by Kuzuki, who learns that her last two attacks had been done on her own free will and that she intends to use the church to obtain the Holy Grail's vessel. After waking up from a dream about Archer, Rin goes to Kirei's church with Archer and finds bloodstains. She concludes Caster attacked Kirei, but that he somehow managed to survive. The two then confront Caster and Kuzuki, but when Rin tries to battle them, Archer suddenly defends them from her attacks. Citing that Saber had been turned over to Caster's side, Archer pledges his allegiance to Caster, revealing that she is the ancient Greek princess Medea and allowing her to stab him with Rule Breaker, which takes Rin's Command Seals. Kuzuki then tries to kill Rin, but she is saved by a recovered Shirō. Caster tries to counter with Golems, but Archer stops her and has her release Shirō and Rin as a condition for him joining forces with her. While on their way back to Shirō's home, Rin confesses that Archer joined Caster because he knew Rin's strategies were hopelessly flawed, though Shirō counters this by telling her that even though she failed this time, it doesn't mean she was wrong. After comforting her, Shirō returns to her the jewel he found at her house, telling her that he had another one at his home. When Rin asks why he rescued her, Shirō confesses that he had feelings for her, which initially embarrasses her. However, she then thanks him for saving her life.
Ep 1414. The Princess of ColchisAt his home, Shirō tells Rin that he plans on continuing to fight in the Holy Grail War, even without the use of a Servant. She replies that she has no choice but to let him before reaffirming their partnership. While discussing a strategy to defeat Caster and rescue Saber, the two decide to team up with Illyasviel, since Archer had told Rin that Berserker is in fact the ancient Greek hero Heracles, which might give them an advantage against Caster. Meanwhile, Caster recounts the time she was summoned by another magus for the Holy Grail War, only to be unsatisfied by his inefficient method of acquiring mana for her. After Caster requested to create mana herself, the magus realized he could not trust a magic user better than himself. As a result, he contacted Kirei and asked for another Servant, but Kirei told him to dispatch Caster first before making another Master-Servant pact. The magus then sent out a contract to Lancer's Master, a colleague, for Caster's death. In the meantime, she destroyed the magus's workshop, and then killed him when he returned and tried to use his Command Seals to force her into committing suicide. She was then gravely injured by Lancer and barely escaped with her life, but she was saved by Kuzuki, who became her new Master. In the present day, Illyasviel observes Shirō and Rin traveling to her villa, then sends out her maids to retrieve them. However, the villa is breached by Shinji and his new Servant, who reveals his knowledge that the Holy Grail's vessel is being held inside Illyasviel. When the maids retaliate in an effort to protect Illyasviel, the Servant kills them with a Noble Phantasm that summons numerous swords and fires them. He is then confronted by Illyasviel, who orders Berserker to attack him.
Ep 1515. A Battle of LegendTen years ago, in the aftermath of the Fourth Holy Grail War, Illyasviel had a vision of her mother Irisviel, who claimed her husband and Illyasviel's father, a participant in the war, betrayed them by refusing to accept the Holy Grail when it presented itself to him. At first, she refused to believe it, but realized the truth when her father did not return home. As time passed, she stumbled upon a room in her home, containing numerous homunculi that were created to serve Illyasviel's purpose, only to fail in their missions. Realizing she too is a homunculus from their dying messages, Illyasviel became disillusioned with her life. Later on, she met her current maids, who assisted her in summoning Berserker. However, she initially did not want it, resolving to participate and win the Holy Grail War by herself. During the final test of her Master-Servant link ritual, she became lost in the nearby woods, being separated from Berserker, and was mauled by a pack of wolves. Berserker rescued her, and afterwards, she realized it was protecting her out of its own free will. In the present day, Illyasviel and Berserker continue their battle against Shinji's Servant as Shirō and Rin arrive to witness the event. As the battle reaches the main entrance, the Servant eventually restrains Berserker using chains fired from his Noble Phantasm, allowing him to impale Berserker with a large spear. Then, he blinds and then stabs Illyasviel with a sword; as she crawls to Berserker's side, it makes one last attempt to strike the Servant, only to be killed. Shirō attempts to intervene, but Illyasviel dies in comfort, believing Berserker is still at her side.
Ep 1616. Winter Days, the Form Wishes TakeAs Shinji's Servant tears out Illyasviel's heart from her corpse, Shirō and Rin confront him and Shinji himself. When Rin threatens to kill Shinji, the two are forced to leave, but not before Shinji reveals his Servant's name as Gilgamesh. While burying Illyasviel, Rin confronts Shirō about his ideals and tells him that he needs to prioritize himself over others, otherwise he will break. He denies this and tells her about the time Kiritsugu rescued him, which caused him to admire him. However, Rin tells him that it is still wrong to value the lives of others over his own, citing that someone who was spared from a terrible tragedy has to live out their life to the fullest and that wishing for the happiness of others is no different from a machine. Despite her argument, Shirō remains committed to his ideals. Later on, as they evaluate Gilgamesh's power and conclude that Caster is still their priority, the two are approached by Lancer, who offers his assistance, which they accept. Meanwhile, Archer learns about Kuzuki's wish to help Caster succeed in her plan to return to her original era using the Holy Grail. Archer later confronts Shirō, Rin, and Lancer as they arrive at the church. Lancer engages Archer to give Shirō and Rin time to breach the church. As they do so, Rin informs Shirō that only one jewel (the same one he previously returned to her) exists in the world, and that Archer had already returned such a jewel to her.
Ep 1717. The Dark Sword Bares Its FangsShirō and Rin confront Caster and Kuzuki, who engage them in battle. Meanwhile, Lancer overwhelms Archer with his attacks, after which Archer mocks his sense of loyalty and honor, thus infuriating him. As a result, Lancer tries to use his powerful Noble Phantasm to strike him down, but Archer is barely able to counter it with a magical barrier, which expends most of his strength in the process and destroys the church. After praising Lancer's power, Archer reveals he staged his betrayal of Rin so he could take advantage of Caster when she had her guard down, prompting Lancer to leave. Back at the church, Shirō and Rin are both overwhelmed by their opponents, but Archer suddenly appears and ambushes Kuzuki, firing several swords at his direction. Caster shields Kuzuki from the swords and is impaled herself. As she dies, she confesses to Kuzuki that her wish was already granted. Kuzuki then tries to fight Archer, explaining that since he had helped in disrupting the usual proceedings of the Holy Grail War, he had to finish what he started. He is then stabbed by Archer and crushed by a collapsing pillar. As Shirō attends to the captive Saber, Archer suddenly traps Rin inside a cage of swords and declares his intention, as a "Guardian", to kill Shirō.
Ep 1818. The Beginning of the CircleSaber defends Shirō from Archer despite her chances of disappearing without a Master to anchor her down to the world, stating that she swore an oath to protect Shirō and that it remains unchanged. However, she is overwhelmed by Archer, forcing Shirō to intervene and take over in the fight. Rin takes advantage of Archer's distraction to form a Master-Servant pact with Saber, which she accepts, therefore making her Rin's new Servant. Fully restored, she subdues Archer, who mocks her for her wish of rectifying her legacy. He then casts Reality Marble, a spell that creates an alternate reality. Shirō, Rin, and Saber are subsequently transported to Unlimited Blade Works, Archer's Noble Phantasm, which is an alternate reality consisting of a barren wasteland filled with swords and levitating gears. Archer creates several duplicates of Saber's sword and fires them at her, but Shirō summons a sword of his own and destroys the duplicates, dissipating Unlimited Blade Works as a result. A weakened Archer grabs Rin, intending to use her as an insurance policy against Shirō and Saber while he recuperates. Before he flees, Shirō tells him to meet up with him at Illysaviel's villa. Later on, a restrained Rin wakes up after having another dream about Archer, and confronts him about his past as a Guardian. Then, Shinji and Gilgamesh arrive, and Archer agrees to give Rin to them for their own needs after he has finished killing Shirō. Back at his house, Shirō tells Saber to let him battle Archer while she rescues Rin, also implying that he knows of Archer's true identity. As they make their way to Illysaviel's villa, they are joined by Lancer, who is also determined to rescue Rin.
Ep 1919. Idealism`s End (The Answer)Shirō, Saber, and Lancer arrive at Illysaviel's villa, where they are met by Archer, who exposits on the true nature of his summoning: Rin had not in fact summoned him by chance, and the catalyst for his summoning was actually the pendent he carries, identical to the one Rin used to save Shirō. While Lancer runs off to retrieve Rin, Saber demands to know why Archer is so intent on killing Shirō. Archer responds that, like Shirō, he aspired to become a hero of justice and actually fulfilled that ideal, but became disillusioned by it and became a Servant so he could rectify it. He then forces Saber to reveal her back-story to Shirō: her true identity is that of King Arthur, who hoped to use the Holy Grail to undo her decision to become the king of Britain, as she believes it was her rule that eventually resulted in the country's destruction. When she then remarks that she and Archer are different in terms of how much they were able to live up to their ideals, Archer elaborates that when he became a Guardian in order to become a true hero of justice, he became disillusioned after he was forced to take lives in order to save many more. He eventually concluded that his ideals were shallow and that it was impossible to save everyone, just as he envisioned. Archer then reveals his true identity: Shirō's future self, the Heroic Spirit Emiya. Meanwhile, Shinji tries to rape Rin, only for Lancer to arrive and incapacitate him. Then, Kirei suddenly appears, exposes himself as Lancer's Master, and reveals he was the one who killed Rin's father in the previous Holy Grail War. He then orders Lancer to kill Rin, intending to use her body as a vessel for the Holy Grail. When Lancer refuses, Kirei uses one of his many Command Seals and orders him to commit suicide, which he does. Back at the main entrance, Emiya tosses Shirō one of his swords and orders him to kill himself with it. However, Shirō refuses, proclaiming that since he learned Emiya's story, he will do all he can
Ep 2020. Unlimited Blade Works.hirō and Emiya begin their battle, with Shirō finding that while he is only barely able to hold off Emiya's attacks, he is slowly becoming stronger the longer he clashes with Emiya. Meanwhile, Kirei prepares to take Rin's heart against Shinji's protests. However, Lancer, mortally wounded but still alive, fatally stabs Kirei. Shinji, on the verge of insanity, takes this opportunity to try and rape Rin again, only to be chased off by Lancer, who lightly wounds him. After freeing Rin, he collapses to the ground and laments how he would have liked for Rin to be his Master. Both Rin and Lancer bid farewell to each other, and as Rin leaves, Lancer sets a fire to destroy both him and Kirei's corpse. Back at the main entrance, Shirō and Emiya continue to battle, with Emiya activating Unlimited Blade Works and slowly gaining the upper hand. As their swords clash, Shirō begins to see Emiya's memories and becomes aware of what his future holds in store for him. With his belief shaken, Shirō is quickly defeated by Emiya and left on the verge of death. As he lies on the ground, Shirō begins to reflect on the memories he gained from Emiya, as well as the memories of Kiritsugu saving him ten years ago. From this, Shirō concludes his ideals are not wrong, and he decides to continue to fight. At that moment, Saber's scabbard Avalon, which Kiritsugu had placed inside Shirō to restore the injuries he sustained from the fire, activates and heals Shirō's wounds. With his confidence in his ideals restored, Shirō prepares to battle Emiya again, with the declaration that he will defeat him.
