Sailor Mars is Hino Rei when she is not in her sailor form. The sailor means super in Japanese, basically Super Mars. She has bad temper, but only when provoked. Rei has long black hair, and was the third sailor scout to re-awaken in the 20th century. She lives with her grandfather in a shrine and spends a lot of her time cleaning and meditating to the fire, which is her power. All of her powers have something to do with fire, and she has a resemblance to the Roman god of war, Mars, in which the red planet is named for.
