Description
Leyseritt, often spelled Leysritt, is a homunculus created by the Einzbern family to serve as a maid, bodyguard, and caretaker for Illyasviel von Einzbern. Despite her adult appearance, she is only about two years old at the time of the story. She has white hair and deep crimson eyes, matching Illya’s coloring. Alongside her fellow maid Sella, Leyseritt resides in the Einzbern household and is responsible for looking after Illya and managing the estate.

In terms of personality, Leyseritt is calm, laid-back, and generally unflappable. She speaks little and often appears relaxed or even disinterested, but she is fiercely protective of Illya and carries out her duties without complaint. Her emotional range is subdued compared to Sella, yet she has developed a sense of reason and loyalty through her bond with Illya. She has a quiet fondness for anime and can become absorbed in watching it, which adds a gentle, homebody quality to her character.

Leyseritt’s primary motivation is to serve and protect Illya and the Einzbern family. She does not pursue personal goals outside of her duty, but she finds contentment in the peaceful daily life that Illya has built. In the events of Fate/kaleid liner Prisma Illya 2wei, she remains a supporting presence in the household, providing occasional assistance and comic relief. She does not drive the main plot but reinforces the domestic environment around Illya, Kuro, and their family.

Her most notable relationship is with Illya, whom she treats with quiet care and obedience. She also works alongside Sella, though the two have contrasting personalities—Sella is strict and formal, while Leyseritt is lax and easygoing. She interacts cordially with Irisviel and other family members. With Kuro’s arrival, Leyseritt adapts without friction, accepting her as part of the household.

Leyseritt is highly skilled in combat, particularly with a halberd, and can serve as a bodyguard when needed. Her most significant ability is the manifestation of the Dress of Heaven, an Einzbern artifact that grants limited access to true magic—miracles beyond conventional sorcery. Activating this ability requires her to sacrifice her life, a measure she is willing to take in extreme circumstances.

Overall, Leyseritt’s development in the series is subtle; she remains a constant, dependable figure in Illya’s life, embodying both the quiet strength of a guardian and the simple pleasures of a homebody. Her presence underscores the theme of family and normalcy that runs through the 2wei season.
