TV Special
Description
Yvette L. Lehrman hails from the Lehrman family, a lineage distinguished by crafting artificial Mystic Eyes using gem cutting and gematria-based host modifications. She openly declares herself a spy for the Neutral Faction's Meluasteas upon joining Lord El-Melloi II's classroom at the Clock Tower, transferring from the Department of Mineralogy.

She sports pink hair with purple tips and favors sweet lolita fashion. A star-shaped eyepatch covers her right eye, concealing an artificial socket where interchangeable gemstones grant varied abilities. Malachite serves as the base gem, its appearance shifting with the activated Mystic Eye.

Her personality mixes provocative flirtation with keen perception, often seeking reactions. She frequently expresses romantic interest in Lord El-Melloi II, aspiring to become his mistress, though her disappointment at Gray's unresponsiveness indicates this behavior partly aims to elicit reactions. She professes enjoyment in deceiving susceptible individuals while disliking those immune to such tactics.

Representing her family during the Mystic Eyes Collection Train incident, regular attendees of the Rail Zeppelin's auction, she helped restore the sabotaged leyline. She utilized her Iolite Mystic Eye to detect magical energy focal points and her Ruby Mystic Eye to incinerate hostile vegetation. Collaborating with Karabo Frampton and Melvin Weins, her shock at recognizing Melvin's identity as a renowned Magic Crest Tuner revealed her awareness of Clock Tower hierarchies.

In the Grand Roll arc, Lord El-Melloi II leveraged her espionage role, tasking her with gathering historical documents on the Department of Modern Magecraft. She delivered these while informing him about factional movements, including the Neutral Faction's absence and Atrum Galliasta's death. Confronting a Chimera alongside Gray, she employed her Mystic Eye of Flame. Her Malachite-based Mystic Eye of Emotion Sight detected deception during meetings with Secret Autopsy Division and Aristocratic Faction representatives.

Her capabilities center on eight documented varieties of artificial Mystic Eyes housed in interchangeable gemstones, swapped manually or via magecraft. Key examples include Malachite for emotional perception, Ruby for pyrokinesis, Iolite for magical energy detection, and Gold for compulsion. Extensive brain modifications approaching sevenfold adjustments per Eye enable this versatility. Post-Rail Zeppelin, Lord El-Melloi II assisted her in developing a beam attack mimicking the train's Mystic Eye Projector. This technique expends an Eye's energy explosively, destroying the gem and temporarily disabling her ocular magecraft.

Beyond the Case Files narrative, she appeared in Snowfield during Fate/strange Fake's True and False Holy Grail Wars as part of the El-Melloi Classroom's response to Flat Escardos's death. She was denied a Command Spell due to potential betrayal based on whimsical inclination.

Beneath her self-aggrandizing spy persona lies loyalty. She consistently provided accurate intelligence to Lord El-Melloi II despite her factional allegiance, aided Gray during investigations, and risked her safety during the Rail Zeppelin crisis.
