Description
Magical Ruby is a Kaleidostick-type Mystic Code crafted by Kischur Zelretch Schweinorg. This sentient magical device empowers its user to transform into a magical girl. Visually, it resembles a toy-like wand featuring a yellow star enclosed in a ring, two small red beads, and six white wings of decreasing size, plus a retractable red handle with a white top and gold cross at the base. When inactive, it levitates using its wings for gesturing, lacking the handle. Shirou Emiya perceives it as a mischievous girl in a kimono despite its non-human form.
Originally assigned to Rin Tohsaka for gathering Class Cards containing Heroic Spirits, Ruby abandoned Rin due to constant squabbling with rival mage Luvia Edelfelt. It independently sought a new master, contracting with Illyasviel von Einzbern after judging her a more suitable candidate. Ruby refers to its counterpart, Magical Sapphire, as its "younger sister," despite simultaneous creation, and exhibits protectiveness towards it. The contracting ritual requires a drop of the user's blood and voluntary grasp of the handle, with Ruby's consent mandatory for activation or termination.
Ruby's personality blends cheerfulness with mischievousness and sadism. It frequently teases or manipulates its users while remaining loyal, particularly to Illya. It warns Illya about the physical dangers of the Kaleido Liner Zwei form, which strains her organs by using them as pseudo-magic circuits. Yet, it often references Illya's crush on her brother, Shirou, and orchestrates scenarios involving mana-sharing kisses between Illya and Chloe. Ruby upholds strict "magical girl standards," chastising Illya for perceived inadequacies.
Functionally, Ruby harnesses the Second Magic to tap into parallel realities, granting its user near-unlimited mana at a regulated rate. This enables high-level magecraft without formal training, limited only by the user's imagination—Illya masters flight by envisioning "magical girls can fly," while Miyu Edelfelt struggles by over-relying on physical laws. Additional abilities include creating shields, enhancing physical attributes, and enduring attacks from Servants like Saber. Ruby also boasts "24 secret abilities," such as a communication mode for contacting Sapphire and statistical future predictions, though these are primarily used for comedic effect.
During critical events, Ruby merges with Sapphire to form the Kaleido Liner Zwei, empowering Illya to defeat Gilgamesh and rescue Miyu after the latter's absorption by the eighth Class Card. This fusion temporarily elevates Illya's capabilities but risks severe bodily harm. In the Prisma Causeway event within Fate/Grand Order, Ruby accompanies Illya into a Reality Marble. There, it analyzes Mash Kyrielight's Shielder class and notes her potential as a magical girl. It flees from Connacht ☆ Medb to seek aid, later reuniting with Illya to battle adversaries like Nursery ☆ Rhyme and Medea while navigating the Reality Marble's challenges.
Ruby's background includes minor appearances in Fate/hollow ataraxia, transforming Rin into Kaleido Ruby during an incident involving Zelretch's Treasure Chest, which caused social embarrassment. It also features in the OVA Prisma Phantasm and the film Licht - The Nameless Girl, maintaining its core traits across all media.
