Lucy Yamagami (山神 ルーシー（略）, Yamagami Rūshī (ryaku)) is a character from the anime Servant x Service.
Lucy is usually seen wearing a black turtleneck together with white pants. She also has a large bust.
Once, she was seen wearing a dress made by Megumi Chihaya.
Lucy was teased by children at a young age because of her long name. She often ran into the library to escape the bullying and, thus, found herself in love with books.
Lucy is very hardworking, making her the ideal civil servant. However, it wasn't like she really wanted to become one. Behind her hard working exterior is a thirst for vengeance. Vengeance against the civil servant who approved her name without asking twice.
She can easily communicate with other people and is very naive. This is observed whenever she is sexually harassed by Yutaka Hasabe and does not even react.
Lucy has shown romantic interest in Yutaka in the latter part of the story. They have eaten dinner together on numerous occasions, and once on an "official" date.
