!!Jun Shigeno
->Live Actress: Arisa Fujisaki

A third-year and member of Miu's cheerleading trio. In Episode 5, Miu promotes her as the head of the Cheerleading team while she's off in her adventures with the Kamen Rider Club.

* BigEater: She's almost always seen eating, and seems to have a preference for candy, potato chips and bananas (a scene in Episode 4 even shows her locker with bananas hanging on it).
* TheCheerleader
* ClubPresident: Promoted to the head of the team since Miu will be busy with the Kamen Rider Club. As shown in #25, she does a pretty good job.
* TheDitz: And yet Miu's trusting her with ''leading the cheerleading team''. Turns out she's good at it, though!
* ShoutOutThemeNaming: To Junko and Shigeru Tama, characters in ''Series/{{Kamen Rider V3}}''.

!!Chosuke Ban
->Live Actor: Tadao Kuroishi

Leader of the delinquents' clique. He and his gang usually hang in a corner near the school, but got their butts handed to by Gentaro. Despite his rough exterior, he does have his nice moments.

* ButtMonkey: Got his (and his clique's) ass handed to him twice by Gentaro in a CurbStompBattle while the latter was seeking information.
* DefeatMeansFriendship: He and the other delinquents attack Gentaro twice with no provocation very early on. Move to episode 17, Ban and the other delinquents are shown to be some of the many students Gentaro has become friends with.
* JapaneseDelinquents: The ''real thing''. Gentaro just styled himself as one; otherwise he's a bona fide NiceGuy.
* JerkWithAHeartOfGold: In Episode 7, he shows JK Teruhiko's local hangout and warns him that the latter was pretty dangerous.
* MeaningfulName: If read in the correct order (Ban Chosuke), the first two syllables form "bancho" (gang leader).

!!Yuri Kuramochi

Part of Ritsuko's posse, she joins to get revenge on the swim team. Gets revenge on them by using 'powers' to control the water.

* EeriePaleSkinnedBrunette: Apparently the reason she was kicked off the swim team.
** That and because she was very slow, or so the members of the team say.
* MakingASplash: Except it's really Altar Zodiarts at work.
* SkunkStripe: Has a stripe of purple.
* WhosLaughingNow

!!Masami Okamura

The other member of Ritsuko's posse. She was originally part of the cheerleading club, but Miu kicked her off due to being more into dating the jocks. She wants revenge on her ex-boyfriend for dumping her.

* TheCheerleader: Originally was part of the Cheerleading Squad before Miu kicked her out.
* ElegantGothicLolita: Especially when compared to Ritsuko and Yuri.
* HairDecorations
* PlayingWithFire: Or at least how the Altar Zodiarts made it look like for her.
* ReallyGetsAround: Miu personally kicked her off the squad because she was more interested in dating the jocks than cheerleading.
* WomanScorned: Joined the coven to pull this on [[DoubleStandard the one footballer that dumped her first]].

!!Reiko Hirota
->Live Actress: Yurika Tachibana

A second-year girl who first appears as JK's pick for a potential competitor against Miu. She reappears in #7-8 and #12.

* BitchInSheepsClothing: In Episode 3, she was seemingly willing to go out and play along with Gentaro's plan in joining the Queen Festival. 5 episodes later we see her dismissing Gentaro as a freak when she breaks up with Shun.
* {{Kawaiiko}}: Plays it up by [[VerbalTic ending all her sentences with -ishi]] and so on.

!!Mari Yamamoto
->Live Actress: Natsumi Ishibashi

A member of the Photography Club and Miura's girlfriend. Unlike all other couples on the show, she remains faithful to him in spite of his troubles.

* CameraFiend: A positive example, she's out to document every spirited smile she sees.
* GenkiGirl: She could rival Yuki for pure energy in her.
* ThePowerOfLove: [[spoiler: Her heartfelt photos of Miura saves him from accepting another Zodiarts Switch from Scorpio. This also makes her a...]]
* SpannerInTheWorks: [[spoiler: Without those photos, Scorpio would've had Miura under her thumb and also helped Scorpio go into a VillianousBSOD.]]
* TenderTears: As if she's taking the {{Retraux}} approach as well by invoking soap opera heroines of TheSeventies.

!!Junta Abe
->Live Actor: Tokimasa Tanabe

President of the Glee Club. He's one of the few students outside of the Zodiarts and the Kamen Rider Club who knows about Gentaro being Fourze.

* SecretHandshake: Gentaro and Yuuki teach him (and the rest of the Glee Club) their handshake.
* SecretKeeper: Not only does he learn that Motoyama, who was his classmate since elementary, is the Perseus Zodiarts, he also learns that Gentaro is Fourze.

!!Rumi Egawa
->Live Actress: Yuki Kato

Kengo's childhood friend and a member of the Track and Field Team, hoping to top an upcoming pentathlon tryout.

* ChildhoodFriends: With Kengo.
* HugeSchoolgirl
* NoGuyWantsAnAmazon: Doesn't help that other members of the Track and Field Team tease her about this (as well as her [[HugeSchoolgirl stature]]).
* NotSoDifferent: Not only does she mirror Yuki's "SavvyGuyEnergeticGirl" relationship with Kengo, but running in a bad stance has led to her developing a chronic condition.
* RedHerring: There's a lot of heavy-handed hinting that Rumi is the Dragon Zodiarts. [[spoiler:It's actually the Track and Field leader, Jin.]]

!!Misa Toriizaki
->Live Actress: Kaya Asano

A student who's into ballet and leads the Cygnus Fan Club/Cult, the Ugly Ducklings. She grades the actions of the other members with a "plus or minus" system.

* BitchInSheepsClothing: Seems like a NiceGirl all dressed in white who wants to spread the goodwill of Cygnus. Then in Episode 24 (for no odd reason), she ditches white for black, becomes a total bitch and [[spoiler:forced Eguchi to become the Cygnus Zodiarts]].
* BreakTheHaughty: The only thing that was done to her was [[spoiler:her being used as a HumanShield and Cygnus stating that she was disposable. After that, the Cult disbands]].
* FanGirl: She leads many of the other fans of Cygnus in a fan club.
* HumanShield: [[spoiler:For letting Eguchi become Cygnus Zodiarts, this was how she was rewarded.]]
* LadyMacbeth: [[spoiler:To the real Cygnus Zodiarts, just as he was about to escape its influence.]]
* LaserGuidedKarma: See above.
* MeaningfulName: The "Tori" in her surname uses the kanji for "bird". [[spoiler:It's another RedHerring.]]
* MyGodWhatHaveIDone: [[spoiler:Learns the hard way that her stupidity nearly got her killed. After that she disbanded the Cult.]]
* NeverTrustATrailer: Where the trailer for 24 suggests she's the Cygnus Zodiarts, even including the shot where she's about to press the switch! [[spoiler:That shot was her forcing the real Cygnus Zodiarts to press and activate the Last One Stage against his will.]]
* NiceJobBreakingItHero: [[spoiler:Was it ''really'' necessary to make Eguchi become Cygnus Zodiarts?]]
* NotHisSled: The trailer to Episode 24 showed her in a black costume and seemingly holding a Zodiarts switch.
* PaintItBlack: Her ballet outfit in Episode 24.
* RedHerring: The look in her eye and her point system ''really'' pegged her to be Cygnus Zodiarts. [[spoiler:It's actually Eguchi.]]
* ShoutOut: A ballerina who appears angelic but turns into a selfish bitch, complete with [[PaintItBlack a black tutu]] - [[Film/BlackSwan sound familiar]]?
* TooDumbToLive: It was ''really'' stupid of her to [[spoiler:force Eguchi - who before then actually resisted the temptation to do so - to activate "Last One". ''It nearly killed her'']].
* UnwittingInstigatorOfDoom: You just ''had'' to [[spoiler:make Eguchi become the Cygnus Zodiarts at Last One despite noticing that he was ''begging and pleading'' not to! All so you can say "Oh, Eguchi! We still need Cygnus so please transform for us"]]!

!!Mei Shirakawa
->Live Actress: Runa Natsui
Ryusei's old classmate from Subaruboshi High.

* BewareTheNiceOnes: [[spoiler:Uses a pipe to hit the Dustards something nasty. [[ActorAllusion This might not]] [[Series/SamuraiSentaiShinkenger surprise some]].]]
* OnlyFriend: With Jiro out of the picture, she's the only one able to fill this role - but it takes time.
* SheIsNotMyGirlfriend: She's working on that, though. [[spoiler:Only for Ryusei to tell Tomoko at the finale to come visit him and to tell her that he's not dating Mei.]]
* ShrinkingViolet: [[spoiler:Although this may be just be a result of the Aries Horoscopes' rule.]]

!!Jiro Iseki
->Live Actor: Ryusei Yokohama
Ryusei's best friend who fell into a coma following a failed attempt to activate a Zodiarts Switch.

* ConvenientComa: His current state. [[spoiler:He returns for good at the end of Episode 32.]]
* IJustWantToBeBadass: He just wants to be as strong as his best friend. [[BeCarefulWhatYouWishFor Then he received a Zodiarts Switch...]]
* OnlyFriend: The only one Ryusei would consider [[spoiler:initially]].
* TooGoodForThisSinfulEarth: Played with. [[spoiler:Jiro survives but, when cured from the effects of the Switch, he is shown to be so pure that he loses the will to live on hearing what Ryusei did to save him. He gets better though.]]
* WhatTheHellHero: [[spoiler:Calls Ryusei out on his treachery to Gentaro all to revive him, before relapsing due to losing his will to live.]]

!!Ran Kuroki
->Live Actress: Rin Honoka

A freshman who is shown to be very angry towards elders, having known to flip them over with martial arts moves. [[spoiler:At the end of the story, she and Kusao Haru join the few SecretKeeper regular students - until they're ready to join the club itself.]]

* BerserkButton: [[HatesBeingTouched Anyone touching her left shoulder gets flipped into the air.]] Even Ohsugi and [[spoiler:Hayami Kouhei]] are not spared.
* CatchPhrase: "I'll protect you, Haru!" is pretty much what she said the most in her arc. [[spoiler: This is also the very same thing that made her friend quicken his evolution as a Zodiarts.]]
* [[spoiler:ChekhovsGunman: Returns in #45... [[WhamEpisode and becomes the Pisces Horoscopes]]!]]
* ChildhoodFriends: With Haru. Unfortunately, her insistence of this makes Haru more and more mad once he got that switch.
* HiddenDepths: She hates seniors because a few of them back in her old school made fun of Haru and tossed his charm bracelet into the pool. She stated that she'd never trust them again after that.
* NiceJobBreakingItHero: Do you wanna know why your friend gets so mad? [[spoiler: Because you won't shut up about "I'm the only one who can protect Haru!" that's why!]]
* OnlyFriend: Invoked. She doesn't believe that someone who wants to be your friend ''can'' be your friend, so she insists to Haru that he trust her. Unfortunately, this makes her ''very'' stupid and slow to realize that maybe Haru doesn't ''want'' to have her always coming to save him and he wants to have other friends besides just her.
* PoorCommunicationKills: Lampshaded and somewhat Justified. Its repeatedly pointed out by Gentaro and crew that if she explained the situation, a lot of problems could be solved earlier. But her paranoia of being betrayed by Upperclassmen keeps getting in the way of considering this.
* UnwittingInstigatorOfDoom: See NiceJobBreakingItHero; Haru ''wanted'' to accept Gentaro's friendship, except she got in the way because ''she's'' the one who didn't trust Gentaro. [[spoiler:However, it's all for the better, since her involvement also clued Ohsugi in on there being a faculty member that's working for the Zodiarts.]]

!!Yukina Takamura
->Live Actress: Mika Akizuki

A classmate of Gentaro who has a massive crush on him, wanting to be with him alone during the School Field Trip. [[spoiler:Unlike the other regular students who somehow learn that Gentaro is Fourze when he reveals it, [[SecretSecretKeeper she discovered it well ahead of time before the trip]].]]

* BetterAsFriends: After Gentaro's fight [[spoiler: with Libra (untransformed since she took the Fourze Driver)]], and Yuki gives her a speech about Gentaro, the two to have a photograph together with big smiles.
* BitchInSheepsClothing: While not as profound as her other fellow female students (ie Rumi, Yayoi, etc.), she shows hints of this when she threatens to confiscates Yuki's Hayabusa puppet if she doesn't do what she says.
** She goes as far as pushing a fellow shopkeeper away and berating Yuki in her kimono because they needed to make her outshine and thus forces Yuki to dress up as a fishmonger. Not to mention force Gentaro to give her a piggy back ride, make him drive her around in a rickshaw and other things.
** [[spoiler: She '''knew''' about Gentaro being Fourze and screams, "Then maybe you should stop being a Kamen Rider." and ''steals'' the Fourze Driver away [[WellIntentionedExtremist ''just so he can relax and have vacation'']]. ]]
* ClingyJealousGirl: She loves Gentaro, and will ''not'' let anyone get in-between the two. [[spoiler: Ultimately gets better in #34 when Yuki explains that Fourze is necessary.]]
** #34 gives more insight; [[spoiler: she knew Gentaro was Fourze and saw how much he was fighting as Fourze. She only wanted him to loosen up and be a normal high school student. Unfortunately, she took it a little too far when she stole the Fourze Driver.]]
* DistaffCounterpart: She acts basically like Gentaro with a greatly decreased sense of empathy.
** A little bit like early [[JerkWithAHeartOfGold Ryusei]] in her ability to switch from kind to jerk at the drop of a hat in regards to their mission.
* {{Foreshadowing}}: At one point claims that she's the only one who understands and worries about Gentaro. [[spoiler: Because she thinks Gentaro's pushing himself too far in his Kamen Rider duties.]]
* IJustWantToBeNormal: Inverted. [[spoiler:She wants ''Gentaro'' to be normal]].
* LockedOutOfTheLoop: Since she's in the same group as Yuki, Gentaro and Ryusei, she usually has to be pushed out of the way else she finds out about the existence of Kamen Riders.
** [[spoiler: #34 reveals that she already knew from watching him at school that Gentaro was Fourze and whenever monsters would appear at school he was fighting them. ]]
* NotSoDifferent: A LargeHam and GenkiGirl who shares the same enthusiasm as Gentaro, and even does his CharacterTic of hitting his chest with a fist twice before extending it out. The only problem? She doesn't want to make friends, but rather wants to be alone with Gentaro to the point that she'll be a complete BitchInSheepsClothing and ensure that the two are ''completely'' alone.
** #34 shows that [[spoiler: she acts like that because she liked him and felt sorry for Gentaro's job in being Fourze, was only trying to do this to make him relax. Of course, [[RuleOfDrama she didn't have to steal the Fourze Driver]].]]
* [[spoiler:SecretKeeper]]
* SlapstickKnowsNoGender: Some of the actions Ryusei uses to keep her out of the loop, [[AgonyOfTheFeet like the]] {{caltrops}}.
* TooDumbToLive: [[spoiler: Let's see: the guy you have a crush on saves the school from monsters almost weekly, you took his means of fighting them because you want him to stop focusing on his mission and enjoy the field trip like a normal kid and almost immediately afterward you are confronted with one such monster (Libra Zodiarts). What are you going to do? Refuse to give the Fourze Driver to Gentaro when he comes to try to save you until Yuki gives AnAesop on how Gentaro with or without the belt to protect people. Good idea. ]]

!!Sarina Sonoda
->Live Actress: Yuka Konan

Gentaro's first homeroom teacher, a youthful and beautiful young woman who teaches classical literature. The students consider her cute, and she's the object of Chuta's unwanted affections. [[spoiler:She is also the true identity of the Scorpion Zodiarts]].

* BeneathTheMask: Despite her popularity and kind demeanor, she can occasionally be heard complaining about the selfishness of her students behind their backs (especially Gentaro "delinquency" and Kengo's standoffishness). [[spoiler:Taken up a notch when it is revealed she is actually the Scorpion Zodiarts.]]
* [[spoiler:BitchInSheepsClothing: After Episode 14, all bets that she's a nice teacher are off.]]
* [[spoiler:BroughtDownToNormal: After being defeated by Fourze, she has her Switch taken away.]]
* [[spoiler:CanisMajor: She was originally the Canis Minor Zodiarts, before she evolved into Scorpion.]]
* CharacterTic: Sucks her teeth in Episode 17, to add to her growing dislike of Gentaro.
** Doubles as a MythologyGag to ''Series/KamenRiderDouble'', since this was Wakana Sonozaki's tic in that series.
* EmbarrassingNickname: Hayami always calls her "My little pup" (Koinu-chan in Japanese). [[spoiler:This refers to her past as the Canis Minor Zodiarts, who has surpassed her Last One phase to become a Horoscopes.]]
* FourIsDeath: [[spoiler: Got her ass beaten by Gentaro in Episode '''14''' and got sent to the Dark Nebula in Episode 18, ''four'' episodes later.]]
* HairDecorations: Hardly appropriate for a high school teacher, [[spoiler:but it turns out to be a mask for who she really is]].
* HiddenDepths: [[spoiler:She's the Scorpion Zodiarts, and before that, Canis Minor Zodiarts.]]
* HotTeacher: [[spoiler:[[HiddenDepths On the surface.]]]]
* MeaningfulName[=/=]SignificantAnagram: The syllables of her name can be arranged as [[spoiler:"sasori nanoda", meaning "I am the Scorpion"]].
* NiceGirl: Seems to be the nicest faculty in Amanogawa. [[spoiler:But that's just a facade.]]
** This may still be a double subversion if you compare her treating Libra with [[spoiler:Cancer and Aries]]
* PutOnABus: [[spoiler:Hayami's official explanation was that Sonoda-sensei had to take sick leave, when actually she was trapped into the Dark Nebula for screwing her last chance to defeat Fourze and Meteor.]]
* ReasonableAuthorityFigure: In contrast to Ohsugi. [[spoiler:Again, on the surface.]]
* SenseiChan: Gentaro even refers to her as "Sono-chan-sensei", despite her gently reminding him "It's 'Sonoda-sensei'."
* [[spoiler:WomanScorned: Becomes this when her Switch was taken away after Fourze defeats her, vowing to work her way back up the ranks of the Horoscopes. However, even when she does get it, she fails.]]

!!Chuta Ohsugi
->Live Actor: Takushi Tanaka

A geography teacher at Amanogawa High with a dislikable personality, and is also the homeroom teacher for Gentaro's class for the third year. [[spoiler: In #30, he has decided to help out the Kamen Rider Club fight the Zodiarts.]]

* AbhorrentAdmirer: To Sonoda. His crush for her was also [[spoiler:the reason the Kamen Rider Club lost their portal locker in Episodes 11-12, thanks to Yuki's lie about that locker originally belonging to Sonoda-sensei]].
* BrickJoke: Remember the RunningGag of him trying to enforce the school dress code on Gentaro? Cue episode 39.
* ButtMonkey: [[RunningGag After finishing his speech, he turns around to find the people he's speaking to have vanished.]]
** Then there's that time where he got run over by many of the female students and mothers in Episode 13.
* CharacterTic: He usually snaps his suspenders.
* ChewingTheScenery: In Episode 18...
** The one at the start of #29 beats that one to a pulp.
* HeroicBSOD: Observing Hayami talking to Sonoda-and subsequently finding out that he has a nickname to her-made him go into complete shock. Happens again when Sonoda [[spoiler:"leaves school"]]. Played for Laughs, of course.
** [[spoiler: And in Ep. 46, he learns that Sonoda-sensei was Scorpio Zodiarts. This is also Played for Laughs.]]
* {{Irony}}: The ButtMonkey out of the faculty [[spoiler:is one of the ''only'' teachers the Kamen Rider Club could actually trust, seeing that he's not a Zodiarts and is actually a normal, human teacher. However, as shown on the show, he's ''not'' that helpful, so even getting the Kamen Rider Club to get a teacher on the inside will be ''immensely hard''. However, after he discovers their hideout, he actually becomes pretty helpful]].
** Remember his belief about how students and teachers must never become friends? [[spoiler:In #33, he tells the Kamen Rider Club that the reason he joined and became their adviser was because he [[IJustWantToHaveFriends just wanted to have friends]].]]
* {{Jerkass}}: Towards the students, especially Gentaro, since it is his belief that teachers and students shouldn't be friends.
** More specifically, he hates Gentaro because he made Sonoda-sensei "leave the school" (he didn't) and is too stubborn to listen to Gentaro about it.
** After #30, he's done a complete 180. See below.
* LargeHam
* LockedOutOfTheLoop: [[spoiler:He's the only member of the faculty - aside from Satake and Haruka - that's ''not'' a Zodiarts.]]
** [[spoiler: However, he soon knows about the Rabbit Hatch, though he's helping out with the club.]]
** [[spoiler:Only to be locked out again, this time regarding Meteor's identity.]]
* MeaningfulEcho: In the beginning of #30 [[spoiler: after finding out about the Kamen Rider Club]] he notes that it was important for teachers to help the students out. At the end of the episode when he gets saved by Fourze from Musca he repeats this same thing, [[spoiler: after he announces that he will become their faculty advisor.]]
* TheMentor: [[spoiler: Becomes this for the Kamen Rider Club in #30.]]
* OnlySaneMan: [[spoiler:His crush hands out Switches to students, their new principal is in on the conspiracy, and the director is the man behind it all. Compared to them, him being the ButtMonkey is ''normal''!]]
** Even more so now that [[spoiler: he's helping out with the Kamen Rider Club.]]
* OOCIsSeriousBusiness: He's shown having a serious face in #47 in regards to the Day of Awakening; ''that's'' enough proof to show how serious this is.
* PapaWolf: We're not kidding. [[spoiler: He tries to pull ''Leo Zodiarts'' away from Miu screaming "Don't harm my students!" and even escapes the Rabbit Hatch to warn Kengo and Gentaro about what's going on. He's going to protect his students no matter what!]]
* ProfessionalButtKisser: Behaves this way towards Miu and Daimonji. Keeping the Kamen Rider Club a secret has allowed Shun to maintain some clout over him in Episode 11 (or maybe Ohsugi's just that gullible).
** Averted in #30 as he actually tries to ''escape'' them when [[spoiler: he's being guarded by them in the Rabbit Hatch.]]
* RedHerring: [[spoiler:In one episode, Sonoda sees him reading the horoscope and asks what his sign is. He responds "Scorpio", making pincers with his fingers and getting a creepy red glow. Turns out Sonoda-sensei ''is'' the Scorpion Zodiarts.]]
* SayMyName: In #32:
-->'''Ohsugi''': ''(to their respective owners)'' KISARAGI! JOJIMA! UTAHOSHI!...''(turns to Ryusei)'' Sakuta?
* SecretKeeper: [[spoiler:Goes with being the faculty adviser of the Kamen Rider Club.]]
* ShooOutTheClowns: After he becomes involved with the KRC, his appearances grow less and less as the other Horoscopes arrive.
* TookALevelInKindness: [[spoiler: After learning about the Zodiarts threat, along with Ran noting that Haru got his switch from a teacher, he decides to help the Kamen Rider Club and be its faculty advisor.]]
** To the point that in #41, [[spoiler: after Virgo has caused the club to break up, he only asks for the remaining members--Ryusei, Kengo and Gentaro--to not die because he truly cared about them.]]

!!Takashi Sakate
->Live Actor: Satoshi Jinbo

A notoriously ruthless teacher responsible for detention classes. Has a great hatred for delinquents due to him having trouble with his own son at home.

* BackForTheFinale
* TheDreaded: In Episode 7 alone, he even makes Gentaro cower before him.
** Getting angry at one point also caused him to strike fear into ''Tomoko''.
* DrillSergeantNasty: Of the academic kind. He spares nobody - not even [[JerkJock Shun]].
* FourEyesZeroSoul: Initially. With the realization that his strictness drove his son to madness, it's safe to say he's getting better.
* GratuitousEnglish: "Bad boy." (to Gentaro)
** IronicEcho: Gentaro repeats these words when he asks if Sakate's son was also one of these. Then again in ''Movie Wars Ultimatum'' when Satake believes Gentaro has cast off the "bad boy" and earned "good man" instead.
* HiddenDepths: The reason he's so ruthless to delinquents is because of his own past with his son...which comes back to bite him.
* MyGodWhatHaveIDone: His son became a Zodiarts because he was such a hardass. Discovering this had a big effect on him. This is exemplified by him repeatedly whispering Teruhiko's name while the latter is in a coma, showing that Satake still loved his son. Once Teruhiko is freed from the Zodiarts Switch, you can see the look of relief on his face as he hugs his son.
* PetTheDog: Perhaps as thanks for helping his son, he gives Gentaro a 50%[[note]]The paper itself shows the final figure had been adjusted from ''18 points''[[/note]] (aka a passing grade) on the test.
* SadistTeacher: At first; with the revelation of his son being Hound Zodiarts, he'll most likely get better.
* [[SimpleStaff Simple Stick]]: Carries one as part of his usual getup.
* VitrolicBestBuds: While he still gives Gentaro a hard time, he comes to respect him as a colleague by ''Movie Wars Ultimatum''.

!!Kouhei Hayami
->Live Actor: Kousei Amano

The charismatic principal of Amanogawa High. [[spoiler: In reality, he's actually the Libra Zodiarts, and is currently handing out the Zodiarts Switches after Scorpion has been demoted.]]

* TheAce: He's got a Ph.D in physics, is so popular-and gorgeous-in the eyes of the School Faculty, the students and their mothers, and is just plain charismatic. [[spoiler: Of course, that's not all he is.]]
* ButtMonkey: [[spoiler: It appears that all the newly evolved Horoscopes do not respect him as much as Sonoda.]]
* CharacterTics: Tends to use words relating to weight, such as "heavy" and "light". [[spoiler:Yet another hint that he's Libra.]]
* {{Foreshadowing}}: His debut episode hints heavily that he is the Scorpion Zodiarts, as he has the same speech patterns and body language. [[spoiler:[[{{Fauxshadow}} He's not]], but he ''is'' the Libra Zodiarts]].
* [[HotTeacher Hot Principal]]: Not only do the female students find him attractive, but so do the mothers of various students. Thus he immediately catches the attention of Sonoda, and the jealousy of Ohsugi. [[spoiler: But, just like Sonoda, this is just a farce.]]
* MeaningfulName: His first name literally translates as "fairness; impartial; justice"; [[spoiler:hinting he is the Libra Zodiarts.]]
* PerpetualSmiler: He carries a smile on his face at all times. [[spoiler:This lapses into DissonantSerenity when he shows his true colours as a ManipulativeBastard.]]

!!Haruka Utsugi
->Live Actress: Nao Nagasawa

Sonoda's replacement as homeroom teacher for Class 2B. She despises her job and would rather make a living on kickboxing then teaching students.

* AdvertisedExtra: A big deal was made out of her appearing in the series due to her actress, but she didn't stay on after the Pegasus Zodiarts' two-parter. [[spoiler:Though she comes back later in both the movie and the finale.]]
* [[spoiler:BackForTheFinale]]
* [[spoiler:BadassNormal]]
* BerserkButton: Prying into her personal life for whichever reason, though this dies down later on.
* CharacterTic: Her trademark kick begins with a quick double-stomp resembling a horse tapping its hooves.
* {{Dismotivation}}: Hates being a teacher and makes it clear that she plans on quitting. [[spoiler:Gentaro convinces her to infuse her job with the passion she has for kickboxing, resulting in her starting a kickboxing club and starting to actually enjoy teaching.]]
* [[spoiler:{{Frameup}}: The real Pegasus Zodiarts goes out of his way to plant evidence implicating Utsugi because he hates her.]]
* IceQueen [[spoiler:-> CoolBigSis [[TheMentor Mentor]]]]
* [[LongLostUncleAesop Long Lost Auntie Aesop]]: Inverted when it was Gentaro teaching her about combining her career and passion and not vice-aresa. Then [[spoiler:she gets PutOnABus [[http://www.jefusion.com/2012/07/nao-nagasawa-joins-kamen-rider-fourze.html until the movie]].]]
* KickChick: Practices kickboxing.
* RedHerring: There were hints that she was Pegasus Zodiarts, her CharacterTic being one of them. [[spoiler:It's actually a student she ''really'' ticked off, who copied her kickboxing.]]
* SecretKeeper: [[spoiler:For Gentaro, because he revealed his identity as Fourze in an attempt to get her to peacefully hand over the Pegasus Switch - which she didn't have.]]
** [[spoiler: But she ''did'' have a switch; she had the switch to the fire alarm cause she kicked it off!]]
* TakeAThirdOption: She was stuck between teaching and wanting to pursue her kickboxing dreams. Gentaro suggests that she just teach kickboxing and form a club.
