Rei Jr, also known as Rei Hino, was a character who existed only in the alternate-universe story "Parallel Sailor Moon." In that story, she was Rei Hino's eight-year-old daughter. Rei was very antisocial, and preferred napping to being around the other girls; she felt forced to hang out with the others because her mother was friends with their mothers.
Rei and her friends Ami, Mako, and Mina all tolerated Usagi's younger daughter, Kousagi, and attended a cooking class taught by Haruka, Michiru, and Setsuna with her, but ditched her whenever possible. Rei was also a Sailor Senshi, but her Senshi name was never given in the story.
- While her name is pronounced the same as her mother's, it is written in hiragana, while her mother's name is written in katakana.
