Sella  

, セラ

The Einzbern family crafted a Homunculus named Sella to function as a maid and sorcery instructor for Illyasviel. Although she resembles an adult, Sella is merely two years old in actuality. She possesses silky blonde hair and deep crimson eyes, similar to Ilya. However, unlike her counterpart, Sella exhibits capricious behavior and feelings of insecurity, particularly concerning her physical appearance. Furthermore, she harbors a strong mistrust towards Shiro Emiya.
