Watch Fate/kaleid liner PRISMA ILLYA

With Shirou down, Illya and the others are completely cornered by the infinite horde of Heroic Spirits pouring out of Julian's dark cube. All seems lost until a mysterious sword appears before them!

The battle heats up as Julian's magic comes undone and he threatens Miyu's friends with a horde of Heroic Spirits pouring out of a mysterious, black cube! Emiya Shirou, Miyu's older brother, rises to the occasion after his rescue.

While Illya is forced to face a fierce battle, Gil and Bazett appear out of hiding to overturn their disadvantages. At long last, Illya's reunion with Miyu draws close!

Sacrifice Miyu and save the world... The Ainsworths' true objective is to use Miyu, the Holy Grail, to save all mankind. The new turn of events sends Illya into confusion.

With Sapphire in hand, Illya transforms into a magical girl while still a stuffed bear. Her fierce battle with Rin and Luvia, whose minds have been replaced, leads them all to the bedroom occupied by Erica and Angelica.

Illya has been kidnapped and taken to the dungeon of the Ainsworths' mansion. Erica wants to grant Miyu's wish to be with Illya, so she swaps Illya's mind into a stuffed bear.

The man who came to pick up Erica proclaims himself as Darius, head of the Ainsworths and Miyu's kidnapper. Using his great power, Darius activates an ice-barrier Noble Phantasm.

Bazett's barrier was supposed to prevent surprise attacks from the dolls, however Illya finds a little girl, Erica, sneaking into their school. For some reason Erica calls Illya "Onee-chan", and the two of them quickly hit it off.

Thanks to sniping from Kuro, Illya's group managed to slip away from Beatrice and retreat from the Ainsworth mansion for the time being. Then they try to regroup at the school building Bazett and Kuro and have been using as their base.

Led by Gil, Illya and Tanaka successfully infiltrate the Ainsworth mansion. Their goal is the room where Miyu's held captive, but standing in their way is Beatrice and Angelica.

One of Ainswoth's dolls, Beatrice, attacks Illya and the mysterious girl, Tanaka. Both are driven into a corner by her overwhelming strength. Just as they run out of options, someone calls Beatrice back, freeing them from their peril.

Illya's fun summer break comes to a sudden end. The aftermath of their battle against the Heroic Spirit of the 8th Class Card disappeared overnight from Mt. Enzou.
