Plot
Illyasviel von Einzbern is an ordinary elementary school student who becomes a magical girl when the magical Kaleidostick Ruby deems her a more suitable master than the sorceress, Rin Tohsaka. Rin, who had been tasked by the wizard Zelretch to collect the seven Class Cards containing the spirits of Heroic Spirits from legend, finds that she is unable to change Ruby's mind and must supervise Illya in completing the task of collecting the Class Cards. During Illya's adventures, she receives a friend and rival in a girl named Miyu, the contracted master of the Kaleidostick Sapphire, which similarly abandoned its original master and Rin's rival, Luvia Edelfelt.

After a series of battles, Illya and Miyu were able to collect all Cards and became good friends, while Rin and Luvia remained in Japan by the order of Zelretch. However, the appearance of Kuro, a dark-skinned girl with a striking resemblance to Illya, soon complicates their lives as she attempts to eliminate Illya. Their battle is interrupted by the arrival of Illya's mother, Irisviel, who reveals that Kuro was originally intended to be the Holy Grail in the Holy Grail War, but after the war was prevented Kuro was sealed away so Illya could live a normal life. Illya supplies Kuro with the mana needed to sustain her physical form, and accepts her into the Einzbern family.

Shortly afterwards, the group is attacked by Bazett Fraga McRemitz, who was previously responsible for obtaining the Class Cards. A truce is forced when Rin reveals the existence of an eighth Class Card. The group confronts the eighth Class Card, Gilgamesh, who reveals that Miyu hails from a parallel world where she was born as a Holy Grail, before absorbing her. Illya combines the Kaleidostick Ruby and Sapphire to become Kaleido Liner Zwei, giving her the power to defeat Gilgamesh and save Miyu.

This victory is short-lived, as Miyu is kidnapped by the Ainsworth family and whisked away into the parallel world. Illya and her friends enter the parallel world and teams up with Tanaka, an amnesiac girl whose goal is to defeat the Ainsworths; Gilgamesh, who wishes to take back his Class Card from the Ainsworths following his defeat by Illya; and a parallel Shirou Emiya, Miyu's older brother who is imprisoned by the Ainsworths. The Ainsworths reveal that they intend to use Miyu as the Holy Grail to save their dying world, but Illya swears that she will find a way to save the parallel world without sacrificing Miyu. Following a confrontation, the Ainsworths escape and Gilgamesh leaves the group after reclaiming his Class Card, while Angelica Ainsworth reluctantly joins the group after being left to die by her family and Miyu and Shirou are liberated.

Main characters

 * Iriyasufīru fon Aintsuberun (イリヤスフィール・フォン・アインツベルン)
 * In contrast with her Fate/stay night counterpart, Illya has had a normal childhood, growing up with no knowledge of magic or the Holy Grail War. She lives with her adored brother Shirou and is looked after by her maids Leysritt and Sella when her parents Kiritsugu and Irisviel are away. She is a fan of magical girl anime, and daydreams about becoming one. When she encounters a magic wand named "Magical Ruby", Illya is tricked into signing a contract and becoming a magical girl. She is also quite naive and carefree in comparison to her original version, even being ready to call herself, Miyu and Chloe as enamoured lesbians to hide their real activity as magical girls.

 * Magical Ruby (マジカルルビー)
 * A Kaleidostick, a magical device that enables its user to become a magical girl. Though Ruby initially belongs to Rin, Rin's constant squabbling with Luvia causes Ruby to abandon Rin and contract herself to Illya instead. Sapphire calls her "nee-san". Ruby has a mischievous personality, and always teases Illya for her own amusement, as Illya's reactions always surpass her expectations.

 * Miyu Edelfelt (美遊・エーデルフェルト)
 * A mysterious girl who is chosen by Sapphire to become her new master and then adopted by Luvia. She takes her duties as a Magical Girl very seriously and is initially dismissive of Illya's abilities, but gradually warms up to Illya, becoming admirative and highly protective of her.

 * Magical Sapphire (マジカルサファイア)
 * A Kaleidostick, the younger sister of Magical Ruby, that enables Miyu to become a Magical Girl. Sapphire was originally assigned to Luvia, but, as with Ruby, Sapphire abandoned Luvia after becoming tired of her constant quarreling with Rin. She is the voice of reason of the duo, and is always serious about her job as a Kaleidostick.

 * Rin Tohsaka (遠坂 凛)
 * A young sorceress sent by the wizard Kischur Zelretch Schweinorg to Japan in order to capture the Class Cards using the powers of a Magical Girl. After Ruby abandons her for Illya, Rin forces Illya to accomplish her mission in her stead, all while guiding and supervising Illya. Though normally competent, her constant fighting with Luvia often causes them to create various embarrassing blunders, leaving Illya and Miyu with a negative opinion of their skills.

 * Luviagelita Edelfelt (ルヴィアゼリッタ・エーデルフェルト)
 * A wealthy and proud young woman and sorceress assigned to work together with Rin to capture the Class Cards. After Sapphire abandons her, Luvia immediately adopts Sapphire's new master, Miyu, and guides her to capture the Class Cards. She is indiscriminate in using her wealth, erecting a mansion across the street from the Einzbern house in a single day, where she and Miyu are currently living. Her rivalry with Rin stems from both their naturally clashing personalities and their mutual crush on Shirou, who fails to notice their attraction to him.

 * Kuro (クロ) Chloe von Einzbern (クロエ・フォン・アインツベルン)
 * A mysterious girl who is identical to Illya, save for her dark skin, white hair and golden eyes, appears after Illya and Miyu capture all the Class Cards. She is an antagonistic presence and her initial goal is to destroy Illya for reasons unknown. Kuro's existence is later revealed to be another side of Illya that was previously sealed away so that Illya could live an ordinary life. In order to maintain existence, she must obtain mana from others by kissing them. After the "power struggle" in the Einzbern house, she is considered the "little sister" of Illya. Chloe is generous with her affections toward both Shirou and any girl she meets, especially Illya. Due to this, she often becomes the main source of yuri fanservice in the manga and the show.

Einzbern family

 * Shirou Emiya (衛宮 士郎)


 * Illya's adoptive older brother, an ordinary young man who seems to often wind up in unfortunate situations. Illya and Chloe have a crush on him and he is rather popular with girls, including Rin, Luvia, Sakura Matō, Caren and Moriyama Nanami (Nanaki's older sister), though he fails to notice that they are openly attracted to him. Shirou tends to be treated poorly by the people around him, though he admits that he's gotten used to being at the bottom rung of the ladder. In essence, he is an open parody version of the original Shirou from Fate/stay night, whose features have been purposely raised to a comic level.
 * An alternate version of him, raised by Miyu's family, appears to have learned magecraft and is more similar in personality to the hotblooded Shirou in Fate/stay night and is currently shackled and imprisoned by the Ainsworth family, but later escaped after hearing that Miyu was in trouble and is assisting the girls in rescuing her.

 * Sella (セラ) and Leysritt (リーゼリット)
 * (Sella)
 * (Leysritt)
 * Sella and Leysritt are maids in the Einzbern household and Illya and Shirou's primary caretakers. Sella is a woman who is easily irritated by the disturbances in the household, but is dedicated to Illya and takes her duties seriously. In contrast, Leysritt is easy-going and doesn't hesitate to shirk her duties and have Shirou do them instead. Nevertheless, she is very enthusiastic and sympathetic towards both Illya and Shirou. Sella has a tendency of thinking that Shirou is a lolicon and siscon, and beats him everytime he has his lucky pervert moments.


 * Irisviel von Einzbern (アイリスフィール・フォン・アインツベルン) and Kiritsugu Emiya (衛宮 切嗣)
 * (Irisviel)
 * (Kiritsugu)
 * Illya and Shirou's parents, who are both often away from home and working hard to make sure their children can live ordinary lives. Irisviel is an eccentric woman who loves Illya and Shirou deeply and has enough skill to knock out Chloe with a single blow. In spite of being away, she and Illya share a close relationship. Though she is a descendant of a long line of magi, she and Kiritsugu left the Einzbern family shortly after Illya was born. Kiritsugu has yet to make a formal appearance in the series, though Shirou expresses the wish for him to return, mostly because he feels downtrodden by the overwhelming female presence in his household.
 * An alternate version of Kiritsugu appears in the alternate world through flashbacks as Miyu's and alternate Shirou's adoptive father, searching for the "Child of God" who could save their world, but is already dead in the present.

Homurahara Academy

 * Taiga Fujimura (藤村 大河)
 * Illya and Miyu's homeroom teacher at school.

 * Tatsuko Gakumazawa (嶽間沢 龍子)
 * A short girl with blonde hair in Illya's circle of friends. She is the most troublesome to the group, and an airhead. She constantly brings trouble to anything they do, like adding nutmeg and mints into pound cake in cooking class (she thought they are making hamburg steaks), even that her father says that she already helps much by not helping at all. Even though she is the heiress to Gakumazawa-style dojo, she has no talents in martial arts at all.

 * A pink-haired girl in Illya's circle of friends. She resents Luvia and Rin (who she calls 'blonde drills' and 'twintails' respectively) for stand in the way of her elder sister's love (her sister likes Shirou Emiya). She happens to be a genius, as she masters the Gakumazawa-style martial art in less than a few minutes but her laziness prevents her from utilizing her talents efficiently.

 * Caren Hortensia (カレン・オルテンシア)
 * The school nurse, a woman who has been observing Illya, Miyu and Chloe. She displays absolutely no interest in the events, and she is rather carefree about her job as a nurse. She is later revealed to be the Church's representative in the affair related to the Class Cards, working as background support as well as supervisor. It is also revealed that she chose to work as a school nurse as it allows her to indulge in her interest in observing the sufferings of children close up.

 * Saber (セイバー)


 * Assassin (アサシン)


 * Berserker (バーサーカー)


 * Gilgamesh (ギルガメッシュ)
 * Gilgamesh is the eighth Class Card that was discovered by Rin after she investigated Fuyuki's Earth Pulses. Though he initially appears mindless and covered in a malignant black fog, he is fully capable of using his entire arsenal of weapons against his opponents. After defeating Bazett and Chloe, he escapes from the mirrored world of the Class Cards and completes a ritual allowing him to separate into two forms: a child version of himself and a gigantic black being that has access to most of Gilgamesh's noble phantasms and desires to win the Holy Grail War. Despite having no intention of winning, he allows himself to merge partly with the black being as he recognizes Illya is a worthy adversary after she combines both Kaleidosticks to become Kaleido Liner Zwei. He is ultimately defeated after a clash of strength between Illya's Kaleido Liner Zwei and his Enuma Elish.

 * Darius Ainsworth (ダリウス・エインズワース)
 * The first head of the Ainsworth family 1000 years ago, Darius escaped death by possessing his descendants. During his first life after a bout of adventuring, he met Pandora, whereupon she told him a horrible truth of their world: it was slowly dying, with mana across the planet slowly but surely depleting and being replaced with something toxic to life. Shook by this revelation, Darius set out with Pandora to overcome this crisis using Pandora's Box, hoping to transform mankind into an existence that could survive the mana depletion.

 * Erica Ainsworth (エリカ・エインズワース)
 * Her real identity is Pandora, the first woman created by the Olympians. In this alternate universe, she never opened Pandora's box and thus became unable to die since her death was also contained inside the box, and eventually became unable to open it. Pandora was eventually found by Darius and has lived with the Ainsworth since then, taking various names over the generations, the most recent being Erika.

After being rescued by Julian when she was being bullied by boys of their school because of her red hair, she fell in love with him and gained more self-confidence.

 * A First-Rank Combat Specialist: Sealing Designation Enforcer from the Magic's Association, sent to retrieve the Class Cards from Illya and Miyu, with force if necessary. She is skilled enough to overpower Rin, Luvia, and Chloe, and nearly defeats Illya and Miyu when they utilize the Class Cards against her. She is relentless with her mission, eventually forcing Rin to announce the existence of a previously unknown eighth Servant card to stop Bazett's assault and bring about a truce. Upon her retreat, Bazett returns the three cards she took from Illya.
 * Following the incident, she went bankrupt (due to Luvia making her pay the whole cost), and works many part-time jobs, notably as the employee of Gakumazawa and mascot "Lion Go-kun" at Gakugaku Animal Land.

Her way of seducing Shirou makes Rin and Luvia dislikes her, and after they throw a bag of dissection frogs at her, Nanami develops a phobia of frogs, which Nanaki notes as sad because her name "巳" means "snake".
