KAMEN RIDER FOURZE (2011-2012) - ALLIES

Kamen Rider Club

The Kamen Rider Club (仮面ライダー部, Kamen Raidā Bu) is a club that Gentaro Kisaragi forms to gain new friends at Amanogawa High School, named after Fourze's predecessors: the various Kamen Riders. The club's members assist Kamen Rider Fourze in his battles against the Zodiarts. In addition, they investigate the urban legends that surround the existence of the past Kamen Riders. The Kamen Rider Club's headquarters are the remains of the Rabbit Hatch (ラビットハッチ, Rabitto Hacchi) lunar base owned by the Over Space Technology Organization (外宇宙技術開発機構, Gai Uchū Gijutsu Kaihatsu Kikō, OSTO) which developed the Fourze technology and the Zodiarts Switches. The Rabbit Hatch can be accessed by a Cosmic Energy (コズミックエナジー,Kozumikku Enajī) powered portal found in a locker in an abandoned part of the AGHS campus.

The television series' producer Hideaki Tsukuda initially planned on including the various past Kamen Riders into the series to commemorate the Kamen Rider Series' 40th anniversary. However, with Kamen Rider Decade having aired recently, this idea was changed into the appreciation of the previous Kamen Riders in their form as urban legends in Japan.

Kengo Utahoshi

Kengo Utahoshi (歌星賢吾, Utahoshi Kengo) is a second-year student and Gentaro's partner who is physically weak but possesses a strong will. His father was an OSTO scientist who devised the Astro Switches before the space station he worked on was destroyed. It would be by chance that Kengo finds a secret locker on the school grounds that holds a cosmic energy-based portal from to the Rabbit Hatch lunar base that remained of the OSTO complex. Though he originally intended to fight the Zodiarts on his own, his physique is so weak that even manning the Powerdizer exo-suit for extended periods of time is an extremely difficult task to him. He is forced to give Gentaro the means to become Kamen Rider Fourze and aid the Kamen Rider by providing him with his arsenal as well as acting as Gentaro's tactician.

Kengo is named after Kamen Rider #1, also known as Takeshi Hongo (本郷猛, Hongō Takeshi); うたほしけんご（歌星賢吾） is an anagram of ほんごうたけし（本郷猛）.

She is a friend of Kengo's and supports him in his activities relating to anti-Zodiarts measures. She is the one who teaches Gentaro how to use the Fourze Driver, as she thinks that Gentaro will be a valuable ally in helping out with Kengo's cause.

Yuki is named after Riderman, also known as Joji Yuki (結城丈二, Yūki Jōji).

Though she is well-loved by everyone at school, Miu has a sense of superiority over the student body and sees those who follow her to be nothing but leeches. This is later used against her during this year's Queen Festival, when leaked footage of her destroying her adoring public's gifts is played in front of the entire student body.

Reiko Hirota

Reiko Hirota (広田玲子, Hirota Reiko) is a student that Gentaro tries to convince to enter the Queen Festival to unseat Miu from her yearly winning streak. However, an attack by the Chameleon Zodiarts scares her enough to back out of the contest. Reiko later becomes Shun's girlfriend after Miu dumps him.

AGHS faculty

The teachers of Amanogawa High School. Several members of the faculty are actually members of the Horoscopes.

Chuta Ohsugi

Chuta Ohsugi (大杉忠太, Ōsugi Chūta?) is the second year geography teacher with a habit of punctuating his sentences with a snap of the suspenders he always wears. He is a middle-aged man who has bad looks and a bad personality who is disliked by many students, as it is part of his belief that teachers should not be friends with students. He is infatuated with Ms. Sonoda, even though she does not have any interest in him and would always walk away when he is about to confess his feelings. Mr. Ohsugi also gets into arguments with Gentaro over him not wearing the mandatory school uniform, among many other things, and has since listed him as the top problematic student in the school. Ryusei also gets on Mr. Ohsugi's bad side by pointing out that Gentaro is within his rights in terms of the dress code not being strictly mandatory. He also happens to be very superstitious, reading the weekly horoscope (he is a Scorpio) and believing in curses. He likes to put up a strong front, only to shirk and cower later when things go haywire. He is also shown to be jealous of Hayami, as he is almost a complete opposite of what he is and Hayami is very close to Ms. Sonoda. He is very obviously devastated in Ms. Sonoda's "absence due to illness" for extended periods, and even more so when being told that she eventually quit her job due to health reasons.

Chuta Ohsugi is portrayed by Takushi Tanaka (田中卓志, Tanaka Takushi).

Takashi Satake

Takashi Satake (佐竹剛, Satake Takashi?) is the teacher in charge of the Sunday remedial class/detention session, where allegedly only the most troublesome students in the school get forced into, and labeled by many students as "Study Hell" (地獄補習, Jigoku Hoshū?) as he is a cruel and unforgiving man who makes his purpose to teach those in his class to become productive members of society. Mr. Satake also has an extreme intolerance towards delinquents, likening them to spots of dirt in a clean campus. He went so far to even call Gentaro a "bad boy" (バッドボーイ, baddo bōi?), as well as giving him more severe punishments than all others in his class. However, after Gentaro saves his son from himself, Mr. Satake has a change of heart and gives Gentaro a passing grade in the test suggested by Shun just to give Gentaro a hard time.

Takashi Satake is portrayed by Satoshi Jinbo (神保悟志, Jinbo Satoshi?). Jinbo previously portrayed Hideyuki Kagawa/Alternative Zero in Kamen Rider Ryuki.

Haruka Utsugi

Haruka Utsugi (宇津木遥, Utsugi Haruka?) replaces Sarina Sonoda as the homeroom teacher for class 2-B, though she is rather uninterested with the job and always muses about quiting her job as a teacher, even in front of the student. She is a well-trained kickboxer and quite wary of her surroundings. Unlike the sour face she puts on at school, she is shown to be truly happy when she is training. She takes up a teaching job only because she is unsure if she can make a living out of kickboxing. Due to her fighting style, she is set up to look like as if she is the Switcher of the Pegasus Zodiarts. Gentaro eventually learns the truth while counseling Ms. Haruka, revealing his identity as Kamen Rider Fourze to her. He tells her that she has to stay true to her path in life, suggesting that she should try to balance her life both as a kickboxer and a teacher instead, just like how he is balancing his life both as a student and a Kamen Rider. Eventually she opts to stay at AGHS, forming a kickboxing club and, to Gentaro's chagrin, insists that he take some lessons from her, as his form is rather sloppy and inefficient.

Haruka Utsugi is portrayed by Nao Nagasawa (長澤奈央, Nagasawa Nao?). Nagasawa previously portrayed Nanami Nono/Hurricane Blue in Ninpuu Sentai Hurricaneger, Lily Shirogane in Kamen Rider W, and Ikechiyo in Daimajin Kanon.

Sarina Sonoda

Sarina Sonoda (園田紗里奈, Sonoda Sarina?) is the youthful and beautiful homeroom teacher of class 2-B who teaches classical literature. Though she appears to be a teacher every student in the school loves, she is actually a member of the Horoscopes who uses her pleasant facade to know the students better in order to find ideal suitors for Zodiarts Switches.
