Yuki Jojima

Yuki Jojima (城島 ユウキ, Jōjima Yūki) is one of the main characters in Kamen Rider Fourze. She is a childhood friend of Gentaro Kisaragi and one of Kengo Utahoshi's only friends along with Gentaro. She is also a member of the Kamen Rider Club, joining the group in her second year and becoming its president during her third year.

Personality
Yuki is cheerful and bright while calling herself a "space otaku", having a deep interest in space science going back to when she was a child and occasionally going to the JAXA building after school. She is also extremely eccentric to the point of worshiping rockets as deities and attempting to illegally add space-themed books into the school library.

Foodroids

 * Main article:Foodroids

The Foodroids are functional spy devices and utility gadgets that aid the Kamen Rider Club. They have a limited amount of AI that allows them to respond to their human companions by way of performing tasks. They also on some occassions have shown initiative to perform tasks that fall under their set of abilities. They are activated by using random Astro Switches.

Hayabusa doll
Since her third year, prior to the Kyoto field trip, Yuki acquired a plush doll modeled after the Hayabusa satellite.

Portrayal
Yuki Jojima is portrayed by Fumika Shimizu (清水 富美加). As a child, Yuki is portrayed by Kanon Kasuga (春日 香音).

Musical Themes
Yuki has a leitmotif, titled "Yuki Jojima", and it has variations in "Hayabusa-Kun" and "Hayabusa Metal".

Etymology
Yuki is named after Joji Yuki from the Kamen Rider V3 series. This allusion is used in the events of Movie War Megamax's Fourze segment when she wears a makeshift Riderman costume. Her name, in the alternate romanization of "Yuuki Jousima", is also an anagram of "I am Soujikyuu" which plays with her connection to the Gemini Zodiarts.

Trivia
It should be noted that Yuki could have been foreshadowed as the light side of the Gemini Zodiarts because the two main writers of the show portray her differently: the heart of the team (light; Nakashima) or a space-obsessed kook (dark; Sanjo).
