Rei's Grandfather (anime)
Rei no Ojisan
Hikawa Shrine, Azabu-Juuban, Minato, Tokyo, Japan
Rei Hino (granddaughter)
In the anime, he is shown as being extraordinarily goofy, jumpy and physical, which worries Rei. Consequently, he and Usagi get along well. He energetically encourages temple visitors to buy lucky charms, make wishes, pray, etc. He is known for his perverted personality, and he once tried to have Ami marry him. In spite of his goofiness, he does manage to come down to Earth when the situation warrants it.
Prior to the anime
During the Silver Millennium, Rei's grandfather was originally Jiji, one of the Seven Great Yuoma that served the Dark Kingdom, until Queen Serenity had him, as well as the other six monsters, reincarnated on earth as normal humans.
On earth, he became Rei's grandfather as well as a Shinto Priest in Tokyo. He opened the Hikawa Shrine, where he both lives and works at. He also developed himself as a pervert towards young teenage girls.
He made his first appearance in episode 10 of the series, when he showed his first signs as a pervert, harassing any girl that visited his shrine. He also hired Shitennou Jadeite, who was disguised as a earthling, to work at his shrine, not knowing Jadeite was actually carrying the plans of the Dark Kingdom. His granddaughter was reawaken as Sailor Mars, whom helped Sailor Moon and Mercury undermine Jadeite's plans. From then on, his shrine would be used as the primary meeting place for the Sailor Senshi.
After Jadeite's departure, he hired a new person named Yuichiro to work at Hikawa Shrine.
Later in the series, the Dark Kingdom tracked down and reawakened the Seven Great Yuoma on earth one at a time and Rei's Grandpa was no exception. He temporarily became Jiji again but Sailor Moon used her powers to turn him back to normal.
Sailor Moon R
His pervert personality went over the top in Sailor Moon R. He harassed so many girls that they all together stopped visiting Hikawa Shrine and a news magazine even published an article about it. He temporarily took a stopped being a priest and took a different career route to attract more girls. His solution was to open a protection aesthetics class, which did eventually attract many females but also the Black Moon Clan, who, tried to use the class to carry out their missions.
- The anime version of Grandpa Hino bares very little resemblance to his manga counterpart in terms of physical appearance; this is one of the very few instances in which a character's appearance changed substantially in the translation from manga to anime.
