An elegant miko (shrine maiden), called Raye in the English version and Raya in the French version. Because of her work as a Shintô priestess, Rei can sense and dispel evil even in civilian form. When she transforms into Sailor Mars, she can also manipulate fire. She is very serious and focused, but although easily annoyed by Usagi’s flightiness, cares about her very much. Rei is portrayed as boy-crazy in the early anime, but is uninterested in romance in both the manga and live-action series. She attends a private Catholic school, separate from the other girls.
