Sella (セラ, Sera?) is a homunculus created by the Einzbern family to serve as a maid and to teach Illyasviel sorcery. Despite her appearance, she is only about two years old.
Overview
Sella is highly protective of Illya, whom she loves and cares for deeply, and thus is very suspicious of Shirou Emiya. She usually wears a maid outfit with a hood that makes her appear almost identical to Leyritt; in casual clothing, she has long pale hair, characteristic of Einzbern homunculi. Sella is rather fickle and insecure, particularly about her body, and she possesses a harsh attitude, which others tend to tease her about. She usually distances herself from humans and prefers to take care of the flora and fauna of the castle.
While she was made on the basis of the same shape as Leysritt, Sella was made as a pure homunculus two years ago with normal alchemy. Unlike Illyasviel and Leysritt, Sella is not a miracle of the Einzbern family, but a homunculus with perfect efficiency. The ability of her body is inferior to others, but she makes up for it with superb magic circuits. As a magic teacher, she is superior, but as she is a fragile homunculus, Sella is unsuitable for battle.
