Fate/kaleid liner Prisma Illya Episode Rating Graph

There is no time to celebrate their hard-won victory, as Saber card suddenly appears to strike down Rin and Luvia. Faced with their strongest opponent yet, which option will Illya and Miyu choose?

Miyu attempts to capture the last card by herself using Saber's power.

After failing to get any information from Kuro, Rin places a seal on her that would cause her pain if anything happens to Illya. When Kuro escapes, Illya has to take drastic measures to keep her from making moves on Shirou. The next day, Kuro causes more problems for Illya when she starts randomly kissing other girls at school to replenish mana. When the two are spotted together by her classmates, Kuro decides to pose as Illya's cousin.

Using her new power, which puts her own body at risk, Illya fights back against the demon while Kuro and the others provide support. As the demon brings out his strongest sword, Ea, Illya uses her full power to defeat it and finally rescue Miyu. Following the battle, Illya and her friends get together to finish their summer homework, with Miyu more than happy to help. Meanwhile, Irisviel and Caren discover the crater has disappeared into a parallel world, where the eighth card is recovered by a mysterious pair.

As Caren experiences backflash from her observation spell, the boy, revealed to be the Heroic Spirit of the eighth card, reveals that Miyu is a princess from a parallel world who was born as a complete version of the Holy Grail. Feeling she can't escape her fate, Miyu gives Sapphire to Illya before being pulled into the vortex, completing the Heroic Spirit's ultimate form. Learning that Miyu is still alive inside the demon's body, Kuro and Bazett hold off the demon while Illya, gathering her resolve to rescue her friend, combines Ruby and Sapphire's power to unleash a powerful new transformation.

Bazett uses her weapon, Fragarach, to counter Miyu's strongest move and take her card, soon setting her sights on Kuro. However, working together with Kuro and Ruby, Illya manages to activate a seal that Rin left behind, allegedly giving her the same curse as Kuro and leaving her unable to harm Illya. Rin also reveals the existence of an eighth card, convincing Bazett to form a truce and leave Illya with half of the cards. As the girls resume their everyday lives and look forward to their trip to the beach, the mysterious eighth card lies in slumber.

Illya and her friends have been defeated by Caster. They must figure out how to improve their teamwork in order to win the rematch.

Illya finds herself targeted by her dark clone, Kuro Illya, whose creation has resulted in Illya's power becoming weaker. Rin and the others attempt to lure Kuro into a trap, but her ability to read everyone's moves leaves them at a disadvantage. However, Illya manages to draw Kuro into a bog, allowing her to be captured.

Illya receives tickets to a theme park from Luvia and decides to go with her friends. When they lose track of Irisviel, who gets swept into a special event, they come across Caren, who agrees to be their substitute guardian. Later, Illya discovers the charm on her bracelet has gone missing, so Miyu decides to help her search for it. Taking some advice from Caren, Miyu manages to deduce the charm's location and find it before closing time. Afterwards, Kuro becomes curious about the relationship between Irisviel and Caren.

Illya wakes up to find she has been kidnapped by the Ainsworths who, after failing to brainwash her, transferred her mind into a stuffed animal, placing a fake personality in her original body. Managing to take control of her new plushy body, Illya tries to chase after her original body but is caught by Beatrice, who brings her to her room. Before Beatrice can rip her to shreds, Illya is saved by the arrival of Rin and Luvia, only to discover they have also been brainwashed into becoming maids. Escaping to the loft, Illya manages to find Sapphire, who gives her the power to transform.

As Gilgamesh and Bazett sneak up from behind, managing to bring Rin and Luvia back to their original bodies, Illya pushes ahead to confront Darius, using a card she received from Kuro to hit him with a dagger planned to cut off his magic, reuniting with Miyu in the process. However, emerging from Darius' body is his son, Julian, who reveals a large black cube in the sky and uses its dark power to consume Erica and create an army of Heroic Spirits. Just as the army seemingly overwhelms them, they are saved by the arrival of Miyu's brother, who bears a strong resemblance to Shirou.

Angelica further explains the situation that because the world's decreasing mana is killing off lifeforms, the Ainsworths intend to use the Holy Grail to change humanity into a species that can survive in this new environment. Forced to use the Assassin Card to escape, Illya, conflicted over choosing between Miyu and humanity, is rescued by Kuro, who states her determination to save Miyu regardless of the situation. As Darius forces Miyu to watch everyone's battle, Illya comes to her own decision, stating her determination to save both Miyu and the world without sacrificing either.

Learning that injuring the possessed bodies will bring their original minds back, Illya, still powerless despite transforming, tries to fight against the possessed Rin and Luvia, who utilise nameless Noble Phantasms to fight against her. As they end up crashing into Erica's room, where Angelica finds them, Illya manages to use split-second timing to return to her original body. As Angelica uses displacement magic to overwhelm Illya, she reveals that the Ainsworths are trying to save their world, which is slowly dying, by using Miyu as the Holy Grail.

The girls learn that the crater created in the mountain during their previous battle has mysteriously disappeared. While investigating the scene, they are suddenly confronted by two new adversaries who overwhelm them and kidnap Miyu. As Illya tries to chase after her, she finds herself in parallel world covered in snow, where she meets a peculiar girl known only as Tanaka. Despite seemingly having no other memories, Tanaka is somehow able to tell Illya that Miyu has been kidnapped by the Ainsworth Family.

Kuro brings Illya and the others to the school, which she and Bazett had been using as a base. Kuro then explains their situation while Bazett gives Illya the Saber, Rider, and Lancer cards. As Gilgamesh explains to Bazett what the cards are, Kuro, notices Illya feeling sorry for herself, confronts her in a battle, forcing her to use the cards she received from Bazett to defend herself. During the battle, Kuro informs Illya that her fears of being in an unknown world are the same feelings Miyu kept to herself all the while. Winning the battle with the Saber card, Illya comes to understand what Kuro was teaching her.

Putting his own body at risk to use his Trace On ability to create weapons, Miyu's brother is aided by Kuro as he battles Angelica while the others fight off the Heroic Spirits. After Kuro manages to use teleportation to defeat Angelica, Miyu's brother goes after Julian but is heavily injured by a mysterious and deranged woman. As Miyu uses the Archer card to confront her, she becomes possessed by it until Gilgamesh retrieves it from her body. As Julian dispels the woman, Illya brings out her full power in an all-out attack.

As Illya's attack fails to stop the regenerating army, Tanaka throws a mysterious sword into the middle of the fray, allowing Illya to damage the black cube and dispel the muck causing the army to grow. As Julian escapes with Erica and Beatrice, Bazett manages to retrieve a gem allowing Rin to properly heal Miyu's brother. After everyone, including Angelica, returns to Miyu's home, Illya and Kuro discover the sword she used was actually Tanaka's arm. While Julian prepares his vengeance, Miyu and her brother tell the others about what happened to them.

The girls attend the local summer festival, where Illya shows Miyu how to enjoy herself. Later, Rin and Luvia get into mischief in front of Shiro, while Illya uses her transformation to escape a wardrobe malfunction. Meanwhile, Kuro becomes aware that Miyu is hiding some kind of secret from Illya.
