Despite her beauty and elegance, Rei has no interest in men. This is due to the fact that Rei had no respectable men in her life, aside from her grandfather. In a short manga story "Casablanca Memories" however, Rei is shown to have a love interest with her father's secretary, Kaidou. He is her father's messenger who would bring her gifts for her birthday which consists of a white dress and a bouquet of Casablanca, her favorite flower.
Beautiful cosplay! Not a lot of people can get Sailor Mars right, but this cosplayer was able to nail it! It makes me wonder if she is actually the actress from the Sailor Moon Live Action Series... Hm...
