Servant (Master: Protagonist)
Illyasviel von Einzbern (イリヤスフィール・フォン・アインツベルン, Iriyasufīru fon Aintsuberun?) is the main protagonist of Fate/kaleid liner PRISMA☆ILLYA. She appears as Caster (キャスター, Kyasutā?), a Caster-class Servant able to be summoned by the Protagonist in the Grand Orders of Fate/Grand Order.
Ilya differs from her Fate/stay night counterpart in many different ways. She was born directly to be utilized in the fourth Fuyuki Holy Grail War, and she was given the knowledge needed at birth. Her father and mother, Kiritsugu and Irisviel, had been discussing completely abandoning the ritual and the Einzbern family, and Irisviel was given the final choice. They decided when Ilya was eight months old, and sealed her magical abilities and her memories up until that point. They remained within her as a separate personality, Kuro, that continued to accrue the same memories as her.
She was brought to Fuyuki from the Einzbern castle and raised as a normal child along with her adopted brother, Shirou. Their parents were away for long periods of time, so they were left with Sella and Leysritt much of the time. She had a normal life for ten years without any knowledge of her background, and had no idea about her parents' activities.
Illya exhibits a cheerful and positive attitude; but unlike her counterpart, she is shy and easily flustered at the beginning. In her first fight, she is shown to be agile but rather cowardly. Also Illya is an ardent fan of anime much to Sella's disappointment. She secretly harbors feelings for her brother, Shirou, something that Ruby highlighted much to her embarrassment.
Fate/kaleid liner PRISMA☆ILLYAEdit
Illya lives as a normal 10-year-old girl with her family in Fuyuki City, not knowing her true nature as a Grail conduit. One day, when she's having a bath, she met Magical Ruby and accidentally made a contract. Rin then confronts her to take Ruby back, but Ruby refuses to return to Rin. So, Rin appoints Illya as her "servant", to collect the Class Card that appears in Fuyuki.
In her first battle, she is cornered by the Rider Class Card manifestation until Miyu Edelfelt helped her. The next day, Miyu transferred to Illya's elementary school and instantly grabs attention with her talents. Meanwhile, Magical Sapphire explains Miyu's situation.
Her next enemy is the manifestation of the Caster Class Card. But, Illya, with Rin, Miyu, and Luvia got defeated very quickly. The only way to defeat Caster is to bypass her magic circle in the sky, so they must fly. Illya can fly easily because of her magical girl imagination, but Miyu can't. So, Illya helps Miyu to learn to fly. In the end, Miyu still could not fly, but they could defeat Caster with two magical girls' teamwork.
Suddenly, the manifestation of Saber Class Card appears and instantly defeat Rin and Luvia. Illya and Miyu then make a plan to defeat it: give the Kaleidosticks to the more experienced magus. Rin and Luvia, in their Kaleid forms seemed to win until Saber unleashes her black Excalibur. At this moment, Illya's seal of her Grail power cracked and she unconsciously Installed Archer Class Card. With Archer's abilities, she defeats Saber.
The next day, Illya comes down with fever and Miyu pays her a visit. They deepen their friendship, while Ruby and Sapphire discuss Illya's true power.
In the fight against Assassin's Class Card manifestations, Illya unknowingly unleashed a devastating magical attack that demolished the enemies and almost killing Miyu, Rin, and Luvia. Scared of her dangerous power, she resigns from her duty as a magical girl.
With Illya leaving the team, Miyu confronts Berserker Class Card alone, and she is cornered. Meanwhile, Irisviel comes back and talks with Illya about life when she is away. Illya comes to realize her friendship with Miyu and decided to help her. Miyu Installed Saber Class Card to fight toe-to-toe with Berserker until God Hand kicks in, and at this time Illya came to help. Together, they defeat Berserker, and with his card, the Class Card collection is completed.
