The Ainsworth Holy Grail War (エインズワースの聖杯戦争, ?) is a ritual started by the Ainsworth, Matou, and an unnamed family in the parallel world. Like Fate/stay night, each of the family provided a container for the wishing device, a land with magical leylines and Heroic Spirit summoning system.
The elder of the family had spent much time collecting Mystic Codes, magical implements, and vessels from around the world to replace Noble Phantasms or the Holy Grail. The items were simply discarded in a large pile, and they eventually obtained the Holy Grail in the form of Miyu. Differing from Illyasviel von Einzbern being born to function as the Holy Grail as part of the Holy Grail War, Miyu was born as the completed Holy Grail and the Holy Grail War was created for her instead.
This Holy Grail War doesn't use the system of Master and Servants, but it uses a special system where a magus uses either a Mystic Code or their own body as mediums and to be granted with the powers of Heroic Spirits via Class Cards.
A group name for a series of pocket spaces that were created by the Class cards. They contain landscape that mirrors the one in the real world, but with no living things present, and with damage done to it not affecting the real world. Their size was originally a few kilometers in radius, but as more cards were collected, they started shrinking until the last one was the size of single building. Their name comes from the analogy that if you put two mirror opposing each other, they would reflect each other infinite number of times, and each pocket space is but a single of such reflections, a mirror image of the world.
Each Class Card was believed to be contained in a separate space, although it was shown that two cards could share a single space.
Mirror World could only be accessed by Kaleidosticks with a formed contract by opening a “Mirror Road” via a spell. After its formation a Mirror Road could immediately transfer several humans to and from the Mirror World before closing.
The supervision of these Holy Grail Wars are again carried out by the Holy Church. However, unlike other wars, while Kirei Kotomine is still the supervisor, he stays as a mere observer and only watches events from the sidelines rather then actively participate.
First Holy Grail War through Fourth Holy Grail WarEdit
There has been four Holy Grail War and they all ended in failure, notably the Fourth Holy Grail War had the worst outcome. Julian Ainsworth caused Fuyuki to be engulfed by darkness, causing Zachary Ainsworth, the previous Ainsworth head and the other two families to be completely destroyed. The Sakatsuki family was also wiped out with Miyu Sakatsuki being the only survivor.
Fifth Holy Grail WarEdit
The next Holy Grail War was again managed by Julian Ainsworth. However, unlike previous Holy Grail Wars, Julian used dolls which had the displaced souls of deceased Magi inside of them acting as the Masters, as there weren't very many people left in town. The other exceptions were Shirou Emiya and Sakura Matou who were the only living Masters. Julian then gave all of the Masters, Class Cards, to which they could install Heroic Spirits into their bodies and had them battle each other in a battle royale.
Shirou Emiya, though, was not originally one of the chosen masters, but rather chose to enter in order to save Miyu Sakatsuki who had been captured by Julian Ainsworth. After gaining the fake Archer card from Sakura and becoming able to install the soul of his future self, the Heroic Spirit, EMIYA, Shirou battled his way through the Holy Grail War, killing all the other masters (except Beatrice Flowerchild who was the user of the Berserker Class Card and managed to survive after their fight) and gaining their cards. Shirou then became the victor of the Holy Grail War and used his wish to send Miyu Sakatsuki to another dimension where she could have a share of happiness. During the time the Grail was working out to make his wish come true, Shirou restrained the true Archer Class Card user, Angelica Ainsworth, facing her with all his might and remaining energy before being ultimately beaten by Enuma Elish. After being sent into Illya's world, Miyu eventually met with Illyasviel von Einzbern beginning the events of the Fate/kaleid liner PRISMA☆ILLYA series.

The events of the Ainsworth Holy Grail War are detailed in Fate/kaleid liner PRISMA☆ILLYA. All Class Cards from the Fifth Holy Grail War remained until the Sixth Holy Grail War. The Assassin Class Card's Hassan-i-Sabbah changes depending on the user.
