Leysritt

Leysritt is a homunculus created by the Einzberns, she deemed a failed creation of the Holy Grail, and tasked as Illya's maid and bodyguard alongside with Sella. Leysritt's main goal is to protect Illya, and since she possesses superior strength compared to other hominculi, she is able to fight with better prowess. However due to her strength, her basic efficiency as a homunculus was sacrificed, and she lacks a complete sense of self, giving her a simple personality. She is also very friendly with both Illya and Shirou, and enjoys teasing her fellow maid Sella.
