Description
Leysritt, often called Liz, is a homunculus crafted by the Einzbern family. Her core purpose is to serve as maid, bodyguard, and caregiver for Illyasviel von Einzbern. Initially labeled a failure in the Holy Grail creation process and marked for disposal, she was instead reassigned to protect Illya. Her design intended her life to be sacrificed to form the Dress of Heaven, a Mystic Code essential for Grail rituals.

Physically, Leysritt resembles a young woman with short pale hair, red eyes, and a notably busty figure. Despite this mature appearance, she is roughly two years old during the Fifth Holy Grail War. She usually wears a maid uniform matching her counterpart Sella, though her casual clothes set her apart. Optimized for combat as a bodyguard, this focus reduced her basic homunculus efficiency. She lacks full sensory perception and possesses a diminished sense of self, leading to a thin ego and stoic demeanor. Her existence is intrinsically linked to Illya's well-being through an empathic bond; Illya's death would cause her own.

Personality-wise, Leysritt displays a casual, laid-back attitude contrasting Sella's strictness. She voices thoughts bluntly, frequently sparking verbal clashes. Though emotionally reserved and sometimes robotic, she shows subtle affection, particularly through teasing Sella or demonstrating loyalty to those who please Illya, like Shirou Emiya. Her emotional development largely mirrors Illya's feelings, forming a pseudo-human personality.

Her role shifts across timelines:
* In the main *Fate/stay night* timeline, she accompanies Illya to Fuyuki City for the Fifth Holy Grail War. She aids in daily tasks and combat, notably confronting Gilgamesh to protect Illya. Disarmed during this encounter, she attacks him upon hearing Illya called "the Grail's vessel" and is killed.
* In *Fate/unlimited codes*, titled "Maid of Heaven's Feel," she defends Illya from Dark Sakura and Saber Alter after Berserker's defeat. Channeling Illya's Magic Circuits grants her temporary power rivaling Servants; she defeats Sakura and Saber Alter, severing their connection to the corrupted Grail. This exertion fatally overstrains her body. She is later resurrected via a new homunculus body fused with her soul, erasing her memories while preserving her core personality and instinctive loyalty to Illya.
* In the *Fate/kaleid liner PRISMA☆ILLYA* universe, Leysritt and Sella act as familial guardians for Illya and Shirou while their parents are abroad. Her personality shifts toward a more easygoing, sisterly role. She neglects maid duties for television and snacks, embodying a relaxed household dynamic. Her relationship with Illya is deeply affectionate, resembling an older sister's bond.
* Minor appearances include *Carnival Phantasm*, where she humorously shadows Berserker on errands, and *Capsule Servant*, aiding Illya (as "Celebloomers") in a Capsaba tournament against Shirou and Shinji Matou.

Her weapon is a halberd, used in combat to intimidate intruders or engage Servants. In *Fate/unlimited codes*, her fighting style includes techniques like "Riesengeschrei drehen" (Giant's Yell Rotates) and "Drei um rauf" (Three from Up).
