Caster is a Caster-Class Servant who first appears in the Prsima Causeway event.
Her True Name is Illyasviel von Einzbern. Initially from a world where she was living an ordinary life as a civilian, Illya gained the power to transform into a magical girl through a sentient rod and, with the introduction of the wands previous user, she was thrust into a number of matters related to not only her own homeworld but of another that was home to that of her friend, Miyu.
Illya appeared in the world of Fate/Grand Order along with Chloe and Miyu to investigate a mirror world incident, only to be separated from the latter two and ending up all alone with Ruby in a world not of her own. Along the way, she met Chaldea and, with their help, managed to save her friends from the hands of the First Lady. Though she parted ways with Chaldea and left for home with Chloe and Miyu, a part of her existed for Chaldea to summon her, allowing her to assist them as one of many Servants to resolve the singularities.

Quintett Feuer: Multi-instrumental Saturation Bombardment: A technique used by Illya in her Kaleid Liner Zwei form which has materialized as a Noble Phantasm upon being summoned as a Servant. It changes Illya’s entire bodily systems, that being her muscular, nervous, circulatory, and lymphatic, to that of magical circuits, granting her a massive increase to her magical output that can rival the light of the planet. In her home world, she was even able to use this against the child form of Gilgamesh and clashing with his Enuma Elish, eventually coming to overpower it and winning their duel.
Magic Resistance: The class ability of the Knight and Rider classes. It is an innate ability that grants protection against magical effects. Unlike the Resistance effect that merely rejects Magical Energy, this ability cancels the spells altogether. Illya’s B-rank Magic Resistance negates spells with a chant below three verses, making it difficult for even High-Thaumaturgy and Greater Rituals to affect her. In addition to this, her transformed state also increases the effects of her other abilities like her physical protection, healing speed, physical prowess, and others. Strengthening their effects in the process.
Child of Nature: A skill representing the miracle of her birth and the hope of her parents who wish for her to live a normal life, granting a blessing unto the young girl.
Infinite Magic Energy Supply: Through her Kaleidostick, Illya is capable of utilizing its infinite mana supply to perform her attacks and many other abilities. However, she is limited to a certain degree of output due to her magical circuits unable to use its full potential.
Pleasant-Type Mystic Code: The mystic code magical stick named Ruby-chan, formally known as “Magical Ruby.” It is a natural human-made spirit contained in the form of a Kaleidostick created by Kischur Zelretch Schweinorg. It has an unnatural obsession with magical girls, and while it does support its owner, it will stubbornly refuse anything other than magical girls.
Suspicious Drug: A mysterious drug that Ruby has crafted in a length of time. Its efficiency is thought to be extraordinary, but due to the behavior of the Kaleidostick, it is generally advised for the master to refrain from its use.
