Saori Hayami

A second-year student at First High School and Tatsuya’s younger sister. She is an exceptional beauty, and unlike her brother, she is extremely talented as a magician. She is constantly ranked at the top of her grade and is especially talented in Freezing Magic. So much so, that she is just as good as Angie Sirius, the Commander of the USNA's magician unit, Stars. She lovingly calls Tatsuya "Brother" and has such an intense brother complex that people mistake them for lovers. She does not forgive anyone who insults her brother. Invited to the New Year’s Banquet, she is gloomy at the thought of attending.
