Rei's Grandfather is Rei Hino's grandfather and the head of Hikawa Shrine.



Rei's grandfather is good-hearted but a bit fond of girls which exasperates Rei. He takes care of Rei because she did not want to live with her father, who is a prominent politician in the National Diet (parliament based on the Prussian system) of Japan.


In the Sailor Moon manga, Rei's grandfather does not appear often. He is first seen in Act 5, who comes to tell Rei that Usagi and Ami (and Makoto) are here to see her. He offers them jobs as a shrine priestess, which causes Rei to become irritated.

He appears again in Act 41, where he has come down with a cold, and Rei has to take care of the shrine. He remembers when Rei came to live at the shrine before starting elementary school. He is the one who told Rei about crows and was there when Rei ran towards two crows and named them Phobos and Deimos. He notes that Rei has always been a mysterious girl and that one day, she will leave Hikawa Shrine and seek her own future.

He also appeared in the Casablanca Memory sidestory.



  • His appearance was radically changed for the anime, and his perverted tendencies were more pronounced.
  • Naoko Takeuchi was frequently hit on while she herself worked at a shrine. This led to Rei's grandfather being a pervert
