Angelina Nanatsu Seawell

Angelina, nicknamed Ange, is a second-year student of Yuihime Girls' Academy. Unlike other female students, she does not wear school uniform, but always wears a maid costume. She is a "stray maid" and hopes to meet her future master someday. She is in Shingo's class and tries to help the students from Kagamidai Academy assimilate. Her father is Japanese and her mother is British, but she speaks only Japanese because she was born and brought up in Japan. She has a cheerful personality and is very good at housekeeping tasks such as cooking and cleaning, but is weak at general educational subjects such as English and mathematics. Her favorite food is tokoroten.
