Characters / Kamen Rider Fourze Zodiarts

Go To

A Zodiarts is created when an ordinary human uses a Zodiarts Switch to create an avatar body of Cosmic Energy, transforming and giving him/her incredible powers. The human (known as a "Switcher") can use the Switch to transform freely between his/her normal and Zodiarts forms as many times as he/she wishes.

After a certain number of uses (catalyzed by the user's rage and negativity) the Zodiarts Switch will mutate into a form known as "Last One". If the Switcher uses the Zodiarts Switch after this happens, their human body is ejected by the Zodiarts body upon transformation. While this increases the Zodiarts's power, it carries a risk that the Switcher will not be able to turn back to normal.


General Tropes

  • All-Encompassing Mantle: Exclusive to the Horoscopes. Until they junk them, that's when shit goes down.
  • Animal Motifs: Sometimes done with Zodiarts based on constellations that aren't animals. Pyxis (also known as the Mariners' Compass) is specifically bug-like, and even Altar (self-explanatory) has bug-like mandibles which combined with her Playing with Fire ability, makes her a firefly.
    • Perseus has a wolf motif to him. Medusa's head (re: the original legend) is even incorporated into the design so he's got a bunch of snakes as well.
    • Libra has antennae and a smaller mantle under his cloak that make him look like a cockroach. And Leo actually did call him a cockroach upon Libra's Heel–Face Turn.
    • Virgo invokes this with deliberately bird-like wings that even shed feathers.
    • Inverted with Dragon — the dragon bits are shifted towards the arms, making him look nondescript.
    • Aquarius is the first to knowingly avert this. Though she does look slightly like a jellyfish.
    • Taurus, of course, looks similar to a giant bull.
    • Sagittarius has a bird motif, as it is the scientific name of the secretarybird.
      • It is a misconception that the myth behind the constellation of Sagittarius, the Archer, is that it was the centaur Chiron, who is actually represented by the aptly named constellation Centaurus. Sagittarius represents the satyr Crotus, so if the Sagittarius Zodiarts was going to be accurate, it'd be a man with goat legs and horns.
      • His Super Nova form's design is a mixture of a Horoscopes Switch and a bug. Interesting enough, in this form he has his own version of a Rider Kick and Punch.
    • Advertisement:
    • Averted again with Gemini, who resembles a jester.
    • Not surprisingly, Pisces is a fish.
  • Deadly Upgrade: Kengo implies that when using a Zodiarts Switch in its "Last One" stage, the user may not be able to turn back. Considering their soul effectively leaves their body in a coma to control the Zodiarts body, he probably has a point.
    • Gentaro mentions in Episode 8 that Miura (Orion Zodiarts) is still in hospital. Then episode 13 comes. He's well, but not going back to Amanogawa due to withdrawal symptoms.
    • Episode 14 reveals that when a former switcher is given a new switch, it immediately enters Last One state.
    • Episode 14 also reveals the true final form of a Horoscope, its Supernova form!
    • Episode 15 reveals that a Zodiarts can surpass the Last One state, which could lead to them becoming a Horoscope. And Episode 22 revealed the first student to become a Horoscope.
  • Drunk on the Dark Side: The users tend to become more irrational and insane as they continue to use the Switch. This is undone with its destruction, however.
  • Evil Feels Good: A frequent consequence of using a Zodiarts Switch. At least one former Switcher - Miura (Orion) - develops withdrawal symptoms after his Switch is destroyed.
  • Advertisement:
  • From Nobody to Nightmare: Invoked in the same way as Kamen Rider Double.
  • The Gloves Come Off: The Horoscopes junk their black capes when they go into battle. Not that there's some kind of Restraining Bolt in action, just Rule of Cool really.
  • Made of Explodium: The released Cosmic Energy could take out an entire city block or more, so Fourze has to be careful when using a Limit Break.
    • Of note, defeating the Zodiarts itself doesn't destroy it completely - the only way to take it out for good is to destroy the Switch by turning it off once and for all.
  • Magic and Powers
    • Personality Powers: The Zodiarts evolve in reaction to their host's abilities and desires. For example Unicorn gained a sword due to Nitta's fencing ability and Hound fit Teruhiko's fondness for chains as its main weapon.
  • Monogender Monsters: Averted in a fashion similar to Kamen Rider Double. Like the Dopants, uncovering the true identity of a Zodiarts is part of the story. To add to the mystery, the Zodiarts refrain from speaking, have their voices digitally distorted, or a separate voice actor is used until their identity is revealed.
  • Monster of the Week
  • One-Winged Angel: Some of the "Last One" transformations.
    • Ramped Up to Eleven #14 as Horoscopes have the ability go Supernova turning them into giant monsters!
    • Taken beyond eleven in in #15. What is beyond Last One? The evolution to a Horoscope-level Zodiarts!
  • Shout-Out
  • Sorting Algorithm of Evil: the latter half of the series eschews normal Zodiarts to have actual Horoscopes as MOTWs, starting with Aries in #31.
  • Stock Superpowers
  • Superpowered Evil Side: The Zodiarts are pretty much extensions of their anger and wrath, but sometimes they can get even worse. Case in point: the case of Cygnus who was, in fact, a student's Split Personality.
  • Weapon of Choice: Some of the Zodiarts have one. These are: Orion, Monoceros, Altar, Hound, Perseus (regular) Libra, Virgo, Aries, Capricorn and Taurus. (Horoscopes)
  • Villainous Breakdown: Apparently the most effective way to accelerate a Switch's evolution to its "Last One" stage.

    The Red-Eyed Man | Mitsuaki Gamou | Sagittarius 

The Red-Eyed Man | Mitsuaki Gamou | Sagittarius

Live Actor: Shingo Tsurumi

Founder of Amanogawa High School, chairman of the board, and former scientist and pioneer of lunar research with connections to NASA and the Russian Federal Space Agency.

He is secretly the mastermind behind the Zodiarts, and has been distributing the Zodiarts Switches amongst the students of his school for reasons unknown. His eyes often glow with an unearthly red light, and he possesses the ability to wield Cosmic Energy in a raw form. At #32, Libra finds out that his Zodiarts form is Sagittarius and he transforms into it in #42.

  • Affably Evil: Gamou is the type to call you over in the cafeteria to try a new soup he's made himself, then a few hours later break into your headquarters and kill your best friend in front of your eyes, apologize for the fuss and thank you for finding the soup delicious enough that he's added it to the menu. What a nice guy.
  • Ambiguously Human: Because Gamou has been using the Switches for so much longer than anyone else, even his human form has power over negative Cosmic Energy that lets him exhibit control over other Zodiarts and even other Horoscopes, usually associated with his eyes turning a bright red color.
  • Arrows on Fire: Which are called Apostolos.
  • Ascend to a Higher Plane of Existence: His ultimate goal is to meet the Presenters and evolve beyond human.
  • Big Bad: The ringleader of the Zodiarts.
  • Bishounen Line: Sagittarius looks like most Kamen Rider final bosses- huge and overdesigned. Supernova Sagittarius is far more streamlined, almost resembling a Kamen Rider himself.
  • Book-Ends: notice what happens at the beginning and ending scenes of #45?
  • Bystander Syndrome: When asked what will become of Japan after his endgame, he pretty much responds that it's up to them. They want to follow his example? good. Japan gets destroyed as he ascends? Not his problem.
  • Drunk on the Dark Side: Gets more and more unhinged as he gets closer to his goal.
  • Entitled Bastard: After Libra gives his life to protect him, Gamou states that he's the sun and Libra was just a planet orbiting him and that's why Libra saved him, not because he actually cared.
  • Evil Overlooker: The newest version of the OP (#35 on) shows him alongside the Horoscopes in this manner.
  • Go-Karting with Bowser: Granted, the club has yet to figure out he's the Big Bad, but he did go out of his way to cook for Kengo's birthday. A big part of what makes him so Affably Evil. He also helps the KRC in the climax of The Movie by being one of the forty switchers.
  • Hidden Agenda Villain: It takes a while for it to come out that he distributes the Zodiarts Switches to students in order for them to evolve into the remaining Horoscopes.
  • Heel Realization: The heroes fighting him, not with hate, but with The Power of Friendship manages to make him see the light in the end.
  • Hoist by His Own Petard: Very nearly happened to him in #46 when he discovers as he's preparing to Ascend to a Higher Plane of Existence that while its happening he's completely powerless. If it weren't for Libra Taking the Bullet for him, he'd have been finished.
  • Hypocrite: While he says he never had a friend and that friendship is useless, he was visibly saddened by Emoto's betrayal and subsequent death and the next arcs are basically him trying to find new companions for his space travel (even going so far as to ask Hayami, who he was treating like crap up to that point, to come with him).
  • It Amused Me: Hayami mentions that this is why there was a "bonus question" in the astronaut qualification test.
    "He was having a little fun."
  • It's All About Me: Gets called this in #45, but really shows it when Libra sacrifices himself for him.
    Gamou: I am the sun, he was simply a planet that orbited me. It's only natural he'd defend me.
  • Jedi Mind Trick: How he got the police to forgo their investigation of the school.
  • Karmic Death: He dies due to the strain his switch put on him. He even lampshades it.
    Gamou: I pushed my evolution too much.
  • Meaningful Name: In a bit of a stretch, the kanji that comprise Gamou's first name are translated as "bright light", which is one of the epithets of the god Apollo, who was also the god of archery, and Sagittarius is primarily identfied as "The Archer", despite its common and mistaken depiction as a centaur. Emoto illustrated this connection to Apollo further when he descibes Gamou as "like the Sun".
  • Mighty Glacier: Monstrously powerful, but his reliance on mostly long range attacks means that he doesn't have to move very fast.
  • My Greatest Failure: He states to Kengo in #34 that he felt sorry for not saving his father, but that might be a lie.
  • Nietzsche Wannabe: He thinks that friendship is useless.
  • One-Winged Angel: Towards the end of the series becomes the Sagittarius Zodiarts. He also gets a Supernova form on top of it.
  • Only Known by Their Nickname: Initially, as "The Red-Eyed Man".
  • Orcus on His Throne: He's mostly been seated on his chair and talking to the Zodiarts. Until he transforms in into the Sagittarius Zodiarts.
  • Pet the Dog:
  • For a toku villain, he seems unusually committed to having his minions not die. He chooses to send those that repeatedly fail him to the Dark Nebula, and he makes an effort to have Virgo rescue those who are taken out by Fourze in space. He even wipes out memories of some of his fellow Horoscopes as an alternative to the Dark Nebula. This can be justified since he only seems to want the Horoscopes Switches instead. When he is eventually forced to kill off one of the Horoscopes, he does seem legitimately remorseful about it.
    • He seemed to generally like (or at least be amused by) Yuuki even before she said she could hear "The Voice of Space"; after that, he tries to recruit her and when he fails laments that he'll be all alone in the end.
  • Rasputinian Death: Takes the Finishing Move of every one of Fourze's States, including Rocket States, in a row (two from Cosmic States), a beat down from Gentaro (read: not in Fourze's Suit!), and finally a quadruple Limit Break from Base States to finally take him down.
  • Real Men Wear Pink: who would've thunk that the Big Bad is an excellent cook?
  • Redemption Equals Death: After Fourze finally defeats him, Gamou finally accepts the latter's belief in the The Power of Friendship — and they do the Secret Handshake. However, Gamou realizes that his abuse of Sagittarius is finally taking a toll on his body. He then walks off and transforms into Aquarius Zodiarts so he could use its healing powers to fix the Core Switch, reviving Kengo in the process, before he fades away into Cosmic Energy.
  • Red Eyes, Take Warning
  • Shed Armor, Gain Speed: His Nova form discards armor, making him fast and powerful enough to defeat Kengo's Core Child powers.
  • Shoot the Dog: In the end, he orders the death of quite possibly his closest comrade and only friend, Emoto. After retrieving Virgo's Switch, he actually seems to feel bad about what he did. For about the span of a few seconds.
  • Villainous Breakdown: After Kengo denies him the entry into the Dark Nebula, he loses his composure and gets pissed, even beating around Leo a bit before unlocking his Super Mode, though he gets a bit better.
  • Villain's Dying Grace: After being defeated by Fourze, resulting in a Superpower Meltdown that will kill him, he uses the Aquarius Zodiarts switch to revive Kengo before dying.
  • Walking Spoiler: Good lord...
  • Well-Intentioned Extremist: If Scorpion is to be believed, he's apparently trying to benefit mankind. It seems he believes that the destruction of Japan would be worth forcing what will remain of humanity to evolve just as he did. Overlaps with Social Darwinist.
  • Ultimate Lifeform: He considers himself this.
    Gamou: I am the apex of human evolution, the Sagittarius Zodiarts.
  • You Monster!: The Kamen Rider Club's reaction to him completely disregarding Libra sacrificing himself for him.



A group of twelve Zodiarts, each representing a constellation of the Western Zodiac. They are direct subordinates to Gamou, giving out Zodiarts Switches on his behalf, and are notably stronger than regular Zodiarts. A Horoscopes member can be identified by the distinctive black robes they wear, which act as Power Limiters to their true potential.

A Horoscopes is created when a Zodiarts exceeds the Last One stage of the Zodiarts Switch, reabsorbing its human body and evolving into an even more powerful form. Only certain talented individuals have the potential to become a Horoscopes; thus, it is the Horoscopes' mission to find and awaken all twelve of their kin.

  • Deadly Upgrade: Kengo's scan of Scorpion Nova implies the supernova power up may be carry some risk to the Zodiarts itself.
  • Five-Man Band: The initial Horoscopes fit into this fairly well, even though they are not all active at once.
  • I Am Not Left-Handed: According to offical materials, their robes limit their power to some degree and casting them off allows them to fight at full power.
  • Mooks: The Star Dust Ninjas called Dustards, which the Horoscopes can create in large numbers.
    • Elite Mooks: Leo Dustards, which Leo is able to create apparently due to being given the Switches of all the Horoscopes except Sagittarius and Libra. They have hair and are considerably more powerful than normal Dustards, but are only created in groups of two.
  • One-Winged Angel:

Scorpion/Sarina Sonoda

Voice Actor: Eiji Takemoto

The Zodiarts representing the constellation Scorpius, the Scorpion. It is the first of the Horoscopes to be seen, and distributes Zodiarts Switches to those who wish to gain revenge. In battle, it uses powerful kickboxing attacks.

  • Absurdly Sharp Blade: The stinger can pierce through the bottom of a metal trolley and stings Gentaro.
  • Beware My Stinger Tail: It has an extendable scorpion tail on its head that can inject a deadly poison into whoever it stings. It was able to sting Gentaro and JK, and merely grazing Shun has that effect, but the three were saved with the Medical Switch.
  • Dark Chick: Being the only lone female of the original Horoscopes, this was obviously her role. Later replaced by Aquarius.
  • Death by Irony: Sonoda-sensei's grudge on Gentaro ultimately defeated her. For added irony, said breakdown was caused by Miura rejecting the Orion Switch after it was offered again to him.
  • Extremity Extremist: Doesn't rely on its hands at all during combat, preferring either its legs or Stinger Tail. She eventually becomes somewhat of a Bare-Fisted Monk, whatwith more common usage of the hands, and especially her legs, in combat.
  • Fate Worse than Death: She gets imprisoned within the Dark Nebula as punishment for screwing up her last chance.
  • Irony: If "The Melancholy of Sarina Sonada" segment of the Net Movies are anything to go by, Sonada had considered giving Yuuki a Zodiarts Switch but deciding against it since Yuuki had no real problems. Had Sonada given Yuuki a switch, regardless of if she was troubled or not, there was a good possibility that Yuuki would have evolved into Gemini, saving her from being banished to the Dark Nebula.
  • It's Personal: Seems to be his preference as to whom he hands out Zodiarts Switches. Which is in line with both myths of Scorpius, where the Scorpion was sent to kill Orion due to a god (Apollo in one and Gaea in another) being offended by him. She herself grows a grudge against Fourze for constantly ruining her plans. It leads to her defeat, as she becomes so fixated on killing him she doesn't even consider taking a Villain: Exit, Stage Left as she'd done many times before.
  • Jack-of-All-Stats: Great at attacking with its bare fists and feet and pretty much sends Fourze flying in almost every battle they have.
  • Samus Is a Girl: Despite the masculine voice, its true identity is Sonoda-sensei.
  • Scorpion People: She gains a One-Winged Angel form that transforms it into a giant with a humanoid top and a bottom with a scorpion's legs and stinger.
  • Starter Villain: Is the first of the Horoscopes to show up and Fourze's first real challenge, but was beaten without even a Midseason Upgrade, and was considered in universe to be incompetent picking Switchers.
  • Superpower Lottery: Inverted. While the other Horoscopes have powers along the lines of invulnerable armor, the ability to steal souls, and the capacity to warp spacetime, having a poisonous tail really fails to measure up. Heck, Scorpio could probably have been beaten by one of the higher-end standard Zodiarts, like Dragon or Musca.
  • This Cannot Be!: Her reaction to Fourze managing to defeat her despite having already gone One-Winged Angel.
  • Villain: Exit, Stage Left: Tends to do this when Fourze is coming close to victory. Until Episode 14, when her growing grudge against Fourze for being too much of a Spanner in the Works gets in the way of her common sense.
  • Villain Forgot to Level Grind: Its problem wasn't getting weaker, but Fourze was getting stronger and it wasn't. It had to be given its One-Winged Angel, as opposed to all the other Horoscopes who got theirs without help.
  • Villainous Breakdown: Develops one in Episode 13, having grown tired of the Kamen Rider Club's interference. Really loses it when Miura rejects the Orion Switch, not only trying to kill him, but going pretty much berserk, gunning for Gentaro's head.
  • With My Hands Tied: Maybe not on purpose, but it doesn't even bother using its hands in its first fight with Gentaro.
  • You Have Outlived Your Usefulness: Subverted. For falling to Fourze even after going One-Winged Angel, Gamou confiscates her Switch and passes the duty of passing Switches to Principal Hayami/Libra for the time being. Played straight in #18 after she pleads for her Switch back but is easily defeated by Meteor. She is imprisoned in the Dark Nebula by Virgo as punishment.

Libra/Kouhei Hayami

The Zodiarts representing the constellation Libra, the Scales of Justice. The second of the Horoscopes to appear, it possesses various powers of illusion and fights using a Khakkhara shakujo. It only distributes Zodiarts Switches to those it feels have the potential to become Horoscopes, and personally mentors them to reach that point.

  • The Bad Guy Wins: Succeeded in destroying the four stations in Kyoto and closing its Hole, which was the mission he was sent on, despite being defeated by Fourze. On top of this, he achieves his Supernova in the process.
  • Bare-Fisted Monk: It should be noted that he seldom actually uses that staff when he fights in one of his disguises.
  • Badass Bookworm: According to Word of God, cut scenes from #45 were going to depict him as this. Before becoming a Zodiarts, he was an astrophysics student, whom at some point met Gamou and joined the Zodiarts.
  • The Dog Bites Back: Has been threatened with banishment to the Dark Nebula quite a few times and was nearly put there at one point. It sort of feels like this when he and Leo killed Virgo. Though this is more The Dog Barks Back, since he had Leo do all the work, then proceed to mock Virgo after death.
  • Dragon with an Agenda: mentions how he wants Taurus for his own, undisclosed-as-of-yet plans.
  • Dropped a Bridge on Him: After taking a hit meant for Gamou/Sagittarius, he gets pelted through the Horoscopes switches-derived portal before it's disrupted and closed off for good. To make things worse, if you pay enough attention, as he's drifting away, you can see Libra get vaporized by a bolt of lightning. He's not trapped in the Dark Nebula or hurtling through space. Libra is flat-out dead.
  • Enemy Mine: He becomes an unofficial member of the Kamen Rider Club after he sees an You Have Outlived Your Usefulness coming from a mile away. It turns out that he was just faking though.
  • Evil Genius: Amongst the Horoscopes, this seems to be his role. He is more manipulative and cunning than his comrades, and has found himself in the role of distributing Zodiarts as part of Gamou's master plan.
  • Evil Mentor: How he goes about dealing with his prospect Zodiarts and Scorpion. The Zodiarts he "mentors" even refer to him as "Master Libra".
  • Famous Last Words: "Master Gamou... did you see? The worth of my existence..."
  • The Force Is Strong with This One: His supernova form allows him to detect those with the potential to become Horoscopes.
  • Foreshadowing: in #37, he expresses sentiments that the astronaut exam would be a good way to spot potential Horoscopes. He got his wish at the end of #38, finding Taurus among the finalists.
  • Heel–Face Turn: He joins the Kamen Rider Club to protect Ran, the final Horoscope. Part of it is fueled by regret for ruining kids lives, but most of it is because he realizes that Gamou plans on riding out the final bit of his plan solo, making him expendable.
  • Heel Realization: After all of his actions, he finally admitted it. Subverted in that he was a Fake Defector
  • Kick the Dog: In #43, alongside Leo, he forced Yuki to push a switch to awaken her potential as the Gemini Horoscopes.
  • Kick the Son of a Bitch: Tricking Virgo into sending Cancer to the Dark Nebula. While he was doing it for his own interests, there's little doubt Cancer deserved it. Later on, he and Leo killed Virgo, though by that point, she too perhaps had it coming.
  • Killed Off for Real: He meets his end when knocked into the Dark Nebula by Fourze, after which he's struck by lightning and killed.
  • Knight of Cerebus: Right after Makise is dispatched, this guy sealed the deal on the Cerebus Syndrome.
  • Locked Out of the Loop: He doesn't have a clue regarding Virgo's identity.
  • Manipulative Bastard
  • Master of Illusion: He possesses several illusory powers, most notably the ability to make itself and others look like other people. At one point he even fights Fourze while disguised as a second Fourze.
  • Master of None: He doesn't have a lot of fighting capability and his illusion powers are only good for distraction.
  • Meaningful Name: His given name (Kouhei) means "fairness", which is in line with his balance motif.
  • My God, What Have I Done?: He has this moment when he realizes just how many people's lives he ruined by giving out all of the astroswitches. Subverted in the end, as he turns out to be a Fake Defector.
  • Nominal Hero: After his Heel–Face Turn. He's the first to admit he is only siding with Fourze to save his own skin, but he will protect Ran at any cost, even if he has to take on Leo without a switch.
  • Pragmatic Villainy: He really takes his role as a mentor to prospective Zodiarts seriously, but, of course, this only ties into the Horoscopes' goal of completing their roster. His abhorrence towards Cancer also counts, since he believes the latter to be too much of a loose cannon anyway.
  • Red Oni, Blue Oni: The blue to Kijima/Cancer and Yamada/Aries' red.
  • Shock and Awe: Can deliver a blast of electricity from his forehead. Said electricity is even able to brainwash Zodiarts, as seen with Perseus.
  • Simple Staff: Wields The Dike that resembles a Khakkhara shakujo, complete with jingling rings.
  • Smug Snake: It's becoming clear that he gives himself too much credit for being "Master Libra" and thinks he's more important within the Horoscopes than he really is. Overlaps with his frustrations that he's turning into The Un-Favourite, while Gamou gives Cancer more leniency. He starts to become even more smug after obtaining the Eye of Laplace, not hesitating to brag about it in Leo's face.
  • Taking the Bullet: Just when Fourze had the chance to finish off Saggitarius, Libra jumps in the way and takes a Limit Break to the chest in his place.
  • Villain: Exit, Stage Left: Is able to teleport, leaving behind a blue nebula like light when he does so.
  • Villainous Breakdown: When he realizes that he's next on the You Have Failed Me chopping block, he doesn't take it well and instead begs like a dog to be spared. This triggers his Supernova transformation, allowing him to perceive who is or can become a Horoscope, an ability that causes Gamou to (understandably) spare him.
  • You Have Outlived Your Usefulness: He sees this coming from a mile away, and defects before the statement can be uttered.

Virgo/Kuniteru Emoto

Voice Actress: Rie Tanaka

The Zodiarts representing the constellation Virgo, the Virgin Goddess Astraea. The third of the Horoscopes to appear, Virgo has various powers of spatial manipulation, such as the power to imprison people in a Pocket Dimension called the Dark Nebula. She first appears fighting against Fourze in Movie War Megamax. In reality, Virgo is Emoto, an old ally of Kengo's father and Gamou, who killed Rokuro Utahoshi prior to the series.

  • The Dragon: While first Scorpion and then Libra served this role directly, Libra's description of her implies she's closer to this role the the first two.
  • Dragon with an Agenda: Gamou doesn't seem to know Virgo's other identity as Tachibana. For starters, he only learned of the latter's existence until the end of Aries' arc.
  • Early-Bird Cameo: Rather like Meteor, she appears in Movie Wars Megamax before debuting at the end of #18.
  • Freudian Excuse: Virgo's abhorrence towards Gentaro's praise of friendship is stemmed from how Emoto's own True Companions (him, Gamou and Kengo's father) ended up becoming.
  • Green-Eyed Monster: Emoto killed Rokuro because, as he states, he wanted to be the "Earth" rather than the "Moon."
  • Killed Off for Real: He's killed by Sagittarius, Leo, and Libra for betraying the Horoscopes, making him the first Zodiarts to actually die.
  • Meaningful Name: Emoto backwards is otome, which means virgin.
  • Pocket Dimension: The Dark Nebula.
  • Power Levels: She states in #32 that Fourze's Cosmic States makes him almost equal to her in strength.
  • Power of the Void: Don't believe me? In her tussle with Meteor in #22, she fired spheres of energy that would have possibly killed Meteor had he not moved. Why? Because one kind of energy sphere Virgo can fire are black holes.
  • Pragmatic Villainy: She objects to letting Taurus control and brainwash the school because individuality is kind of necessary for kids to want to use switches.
  • The Reveal: Her identity is quite well-hidden for most of the series. Also, the series' opening scene with Kengo's father fighting against a red-eyed astronaut? It wasn't Gamou, it was this guy.
    • And another reveal happened AGAIN in the very next episode, where she is Tachibana, the one who made Kamen Rider Meteor!
  • Samus Is a Girl: An inversion. Virgo's true identity is none other than Kuniteru Emoto, aka Tachibana, a male character who transformed into a female-themed monster.
  • The Smurfette Principle: Currently the only member of the Horoscopes that's clearly female.
    • Has now become one of the Dark Chicks of the season, what with the debut of the female Aquarius.
    • Subverted.
  • Cast as a Mask: Rie Tanaka only features as Virgo's voice in Zodiarts form.

Cancer/Natsuji Kijima

The Zodiarts representing the constellation Cancer, the Crab sent to distract Heracles from his tasks. The fourth of the Horoscopes to appear, it possesses an incredibly tough skin that makes it hard to damage and sharp pincers that can slice through anything. It evolved from Pegasus.
  • Absurdly Sharp Blade: His open claw is even capable of cutting through Fourze's shield, which is made of a super-durable metal called Astorium.
  • And I Must Scream: Libra and Virgo handle his punishment — Libra transforms him into the policeman that hounded Gamou in #27, and then tricks Virgo into sending him into the Dark Nebula, with his fan left behind.
  • Deadly Game: How he hands out Zodiarts Switches. He calls it "Open Mic From Hell". You make him laugh? Congratulations, you get a Zodiarts Switch! You fail? Say goodbye to your soul.
  • Faux Affably Evil: The fact he's polite and cheery just makes him more disturbing.
  • For the Evulz: How he approaches students with Switches. He basically asks if they want to have fun. Made even worse in #27. He takes a couple of athletes' souls away because none of them could make him laugh. And those that could were given a Zodiarts Switch instead!
  • Fireballs: One of his abilities.
  • Giant Enemy Crab: Moreso when Supernova form kicks in (#27).
  • Ham-to-Ham Combat: One-sided, actually. During his fight with Meteor in #27, he would not shut up.
  • Hoist by His Own Petard: He would free the souls of the KRC he imprisoned should one make him laugh. Ryusei engages him in battle and the sight is so hilarious to Kijima that he laughs...which is what Ryusei wanted him to do.
    • Another thing that really bites him in the ass was keeping the identity to Meteor to himself. If he had explained it to Gamou instead of promising to tell it later, he'd probably would still be a Zodiarts.
  • Irony: Cancer was supposed to pinch at the toes of Hercules while Hercules battled the Hydra. Hercules squashed him pretty easily. Here, Cancer's been really hard to destroy due to his powerful armor and the fact that he runs away just before Gentaro puts the finishing blow on him.
  • Kill It with Fire: Thus far the only thing capable of damaging him. Until #28, that is.
  • Laughably Evil: Seems to be an intentional tactic of his to get under his opponents skin and confuse them. Makes him even more disturbing when he does stuff like steal people's souls.
  • Lightning Bruiser: Fast, strong and takes most hits without a scratch on his shell.
  • Making a Splash: Another of his abilities.
  • Meaningful Name: The kanji of his given name can be read as "kani" (Japanese for "crab") based on the on'yomi pronunciation.
  • One-Winged Angel: Cancer Nova. Worse? He managed to reach it without help!
  • Psycho for Hire: Unlike the other Horoscopes who seem to be Well Intentioned Extremists, Cancer is just a Sociopath who enjoys what he does.
  • Red Oni, Blue Oni: The red to Hayame/Libra's blue. (One of two)
  • Sixth Ranger: His role amongst the Horoscopes. The first to surpass Last One and become a Horoscopes since Sonoda/Scorpion, he was also responsible for dishing out The Worf Effect for a good while before his enemies one-upped him.
  • Shadow Archetype: As stated before, Cancer is one to Ryusei/Meteor. This was even Lampshaded by Cancer in 27. Both are liars, hiding a secret from everyone. At first, Kijima was hiding his identity as Pegasus, though he did drop that act when he became Horoscopes. Ryusei, meanwhile, has been hiding his identity as Meteor. The parallels between the two of them are drawn constantly, with Ryusei even being the one to discover Kijima's identity as a Zodiarts, and Kijima being the first person to learn of Ryusei's secret identity.
  • Super Toughness: And how! He's basically immune to everything that Fourze can throw at him, except for prolonged exposure to fire and Kamen Rider Meteor's Finishing Move.
  • We Can Rule Together: Cancer makes this offer to Ryusei in exchange for keeping mum about his secret identity.
  • Xanatos Gambit: His way of handing out Zodiarts Switches. They make him laugh? He hands out a Switch and a Zodiarts is let loose, continuing his mission. They don't? He gets their soul and becomes more powerful.
  • You Fight Like a Cow: Mostly in his battle against Meteor.
  • Your Soul Is Mine: Type A. In #27, he was able to collect souls that look like rings and then snip them with his pincer, sending their owners into comas in the process. And he does it on the Kamen Rider Club in #28, almost snipping off Tomoko's had Ryusei not come in in time.

Aries/Tatsumori Yamada

Live Actor: Kazuma Kawahara
The Zodiarts representing the constellation Aries, the Ram with the Golden Fleece. The fifth of the Horoscopes to appear, he can control the mental facilities that regulate sleep, tranquillising those who resist his will. His alter-ego is Tatsumori Yamada, a transferee to Subaruboshi from Amanogawa.
  • Astonishingly Appropriate Appearance: Well of course the Zodiarts that controls sleep would be the one that's a sheep.
  • Chekhov's Gunman: He was actually name-dropped in #17, 14 episodes before he made his debut.
  • Convenient Coma: He can induce this upon anyone else. Ironically, he's now in one of these.
  • Deal with the Devil: He gave one of these to Ryusei to save Jiro, in the cost of killing Fourze. He then paid his end of the bargain and revived Jiro.
  • Death by Irony: Almost. He's last seen lying comatose in hospital after losing his Switch.
  • The Dreaded: Among Subaruboshi students.
  • Early-Bird Cameo: In #30, after Meteor's brief altercation with Libra at Subaroboshi, someone in an Amanogawa uniform ominously walks past.
  • Expy: He's an amoral AGHS student who uses his Zodiarts Switch to torment others For the Evulz and is actively opposing Hayami — just like Kijima, the Cancer Zodiarts.
  • Hidden Depths : Bastard that he is, it's still worth mentioning that he doesn't back out of his arrangement with Ryusei. Mind you, it goes horribly wrong, but he did heal Jiro. Granted we never found out why so it could be pragmatic villainy
  • Irony: Ryusei transfers to Amanogawa in search for Aries, except that Aries was the student who transferred to Subaruboshi in his place.
  • Killer Rabbit: Tatsumoi supposedly transcended the Lepus.
  • Karmic Death: After being defeated by Fourze, he is shown in the hospital in a coma, just like he did to his victims.
  • Meaningful Name: The kanji in his name mean "dragon" and "guard/protect." In Greek mythology, Aries was a sacred golden ram whose fleece was guarded by a dragon.
  • Monster of the Week: The other Horoscopes are dangerous, long-term threats; Yamada, on the other hand, is essentially this, with some backstory relevance for Ryusei.
  • New Transfer Student: To Subaruboshi High.
  • Powerup Letdown: He attempts to use Supernova against Fourze Cosmic States, but since he hasn't earned it himself or been granted it by Gamou, all that happens is his horns get bigger and removes the cape.
  • Prima Donna Director: With his power over Subaruboshi, he forces all the students and teachers to act in the plays he writes and knocks out everyone who he feels isn't up to snuff. The KRC's general reaction to his scripts is "Who Writes This Crap?!", and he's shown to be lousy at casting too (he turns the Judo Club into the Space Club, and when he criticizes a teacher's English she protests that she teaches gym).
  • Red Baron: He's known as the "Apostle of Sleep".
  • Red Oni, Blue Oni: The red to Libra's Blue. (One of two)
  • Remember the New Guy?: Flashbacks to the first episode show that he was there even though he's only actually introduced much later. He was also mentioned in Episode 17 (Ryusei's debut) when both Gentaro and Sonoda note that Yamada was gone.
  • Shockand Awe: Emits electricity from his horn to paralyze people. Though, it's only use in the Net Movie so it might not be canon in the show.
  • Simple Staff: Coppelius Scepter.
  • Sixth Ranger/Sixth Ranger Traitor: His role amongst the Zodiarts. Though when he mouths off to Libra and decides to do whatever he feels like, you could consider it as him "betraying" Libra.
  • Squishy Wizard: His staff is pretty much his only means of one-upping his opponents. Once Fourze got Cosmic States, he went bye bye.
  • Standard Status Effects: Has the power to put anyone he touches with his staff to sleep or shut down the use of the Astroswitches temporarily.
  • Tyrant Takes the Helm: He took over Subaroboshi with an iron fist.

Leo/Kou Tatsugami

Live Actor: Kazutoshi Yokoyama
The Zodiarts representing the constellation Leo, the Nemean Lion. The sixth of the Horoscopes to be formally introduced in the television series, although he is featured in the opening title sequence and made a few non-speaking cameos beforehand. He is a proficient and deadly fighter. His true identity is Kou Tatsugami, Gamou's bodyguard.
  • All Your Powers Combined: He has been entrusted the Switches of past Horoscopes by Gamou for safe-keeping. He can use them to take the forms of past Horoscopes like Aries, Aquarius, Cancer, Capricorn, even Virgo.
  • Berserk Button: He flipped after Gentaro approached Gamou without a regard for the latter's position. Gamou even held him back to make him keep his cool, but that didn't stop Leo from delivering a No-Holds-Barred Beatdown to Fourze unprovoked later that night.
  • The Brute: Compared to its fellow Horoscopes Zodiarts. He's also the naturally tallest of the bunch.
  • The Cast Show Off: Kazutoshi Yokoyama was originally a stuntman for JAC, the stunt group for most Kamen Rider series. As such, he has some amazing untransformed fighting scenes, prime example would be his fight against Ryusei in #47.
  • Character Tics: Manipulates walnuts in his hands, similar to Baoding Balls.
  • Dark and Troubled Past: It is revealed in episode 47 that Tatsugami was nothing more than an ally-way brawler drunk on the power of his fighting prowess. It all changes when Gamou presents him with a Zodiarts switch.
  • Dragon Their Feet: We've seen Fourze gain five powerups, three Horoscopes have been lost (though they assume that they could just get two of them back from the "Dark Nebula"), and this guy didn't act in any fashion. Justified with his role as Gamou's bodyguard, instead of handing out Switches like Scorpio, Libra, and Cancer, an executioner like Virgo, or just fooling around like Aries.
  • Dragon with an Agenda: Leo hints at looking for a McGuffin called the "Core Switch", and mentions that it will surprise even Gamou, indicating that the latter has no idea. Though unlike most cases of this, he is completely loyal to the Big Bad, and was apparently just trying to help further Gamou's plans.
  • Dumb Muscle: Even if he managed to help Libra's plan to get Picses, he's not usually assigned to recruit Zodiarts because his general M.O. is "just press the switch already!"
  • Evil Counterpart: Could serve as this to Either of the Kamen Riders, really. Like Gentaro, he is devoted to helping his friend (Though it does border on an unhealthy obsession at times), and like Ryusei he holds a great amount of martial arts expertise. Also like the Kamen Riders, he can change out what Switch he's using to gain new powers.
  • Expy Lion-motif kaijin who takes powers from his comrades to fight and is The Dragon to the Big Bad. Just like Kazari.
  • The Juggernaut: Thus far has been pretty much unstoppable to everything thrown at him, including both Fourze Cosmic States and Meteor Storm, and having the power to go with it. In human form he can withstand the one-inch punch. You know, that same punch that killed Gentaro?
  • Kick the Dog: In #43, alongside Libra, he forced Yuki to push a switch to awaken her potential as the Gemini Horoscope.
  • Killed Off for Real: Courtesy of Meteor Storm.
  • Make Me Wanna Shout: Has a powerful roar that can cause shockwaves.
  • Meaningful Name: His family name sounds similar to tategami, meaning "mane", while the kanji used for his first name means "roar."
  • Mighty Glacier: Tall, slow and powerful. He can pummel both Cosmic States Fourze and Meteor Storm without breaking a sweat!
  • Wolverine Claws: Can turn his forearms into a spectacularly large set.
  • You Have Failed Me: tells Libra that should he fail the Kyoto mission, it will also be his last.

Capricorn/Toujiro Goto

Live Actor: Ryousuke Kawamura
The Zodiarts representing the constellation Capricorn, the sea goat. The seventh of the Horoscopes to appear, he can freely manipulate sound to his advantage. He's a student who turns out to be an old friend of JK's and wishes to reform their old band to become superstars.
  • Anime Hair: His is all spiked up.
  • Anti-Villain: Type IV. He's the least malevolent of any of the Zodiarts, and really just wants to play music rather than hurt anyone. He initially only fights because Fourze attacks him first.
  • Cut Lex Luthor a Check: He becomes Capricorn so he can further his music career.
  • Dreadful Musician: In human form, but not in Zodiarts form.
  • Foreshadowing: He was tasked by Gamou to find the Core Switch, and his powers apparently resonate with it. And there's one student who was most affected by said power...
  • Laser-Guided Amnesia: After being defeated by Fourze, his memory was wiped by Gamou.
  • Magic Music: Can create Music Staffs to entrap his opponent, or entrance them.
  • Meaningful Name: "Goto" sounds like the Japanese pronunciation of "goat".
  • Monster of the Week: Capricorn was treated similarly to Aries. Instead of being a general like Leo, Libra, and Virgo, he was just a Monster of the Week with backstory relevance for JK.
  • Shout-Out Theme Naming: His name is turned into his old nickname by shortening further till it's read roughly like GOD, antagonist organisation to Kamen Rider X — which JK was named for.
  • Squishy Wizard: Like Aries above, he only uses his guitar as a means of attacking. Once Fourze ensnared him with his own music, he was done for.
  • Spoony Bard: His Multi-Stringed Koto Uruk which is only used to blast a Musical Staff to ensnare his opponent. He doesn't use the music to brainwash his opponents (Ryusei notes that both he and Gentaro are immune to his song due to being shielded by Cosmic Energy) nor actually use it to his advantage (say, make the rave zombies to shield him so that the Riders can't touch him), and once Cosmic States captured the music he played, he had nothing left in his arsenal. It's this even outside of battle; when he plays his guitar the power of the Zodiarts Switches intensify. Moreover, the only reason he gets the power of Supernova was so that he can use it to see whether or not Gamou can sense the power of the legendary Core Switch.
  • We Used to Be Friends: With JK. The end of #36 shows that they're hanging out again though.
  • Villainous Breakdown: After seeing Gentaro both steal the show and turn JK against him, he really loses it. Though this may have something to do with the Supernova energy Gamou put in him.

Aquarius/Erin Suda

The Zodiarts representing the constellation Aquarius, the Water-Bearer. The eighth of the Horoscopes to appear, she is able to use Cosmic Energy to heal herself. Erin is revealed to want to pass the mock space exam to become an astronaut like her father and will not let anyone stand in her way...not even Genki Girl and her rival, Yuki Jojima.
  • The Ace: Transfer student from America who is smart, athletic and super-hot as JK puts it. This is even lampshaded with the letter A on her chest in regards with the exam.
  • Anti-Villain: Another Type IV. Her first order of business as a Zodiarts was to heal Kengo, and she's only hostile to Gentaro because of his friendship with Yuki. After learning what really happened with the robot test, she does the Secret Handshake with Yuki and asks for a battle with Fourze. She then thanks Gentaro before Virgo retrieves her and erases her memory.
  • Book-Ends: Her last scene shows her "first" meeting with Gentaro and Yuki in front of the JAXA monument, just like when she was first introduced.
  • Borrowed Cathcphrase: Another to put her own spin on the “Uchuu Kita” phrase.
  • Dark Chick: Apart from Virgo, she is the only Horoscopes that is obviously female in appearance. Now that we know who Virgo really is, it seems Aquarius and Scorpio are the only Dark Chicks around.
  • Death Glare: Has this down to a fine art.
  • Expy: Let's see. Serious Business about something? Check. Hates Genki Girl Yuki but doesn't have qualms with anyone else? Check. Has a Pet the Dog moment despite being a Zodiarts? Definitely. Gets talked to by Gentaro and immediately has a My God, What Have I Done? moment shortly thereafter? Yep. Said My God, What Have I Done? moment coincides with something in relation to Yuki Jojima? Uh-huh. She's pretty much the Horoscopes version of Motoyama (Perseus).
  • Foil: To Yuki. Where Yuki is hyperactive, loud and energetic, Erin is calm, quiet and still. Where Yuki believes in praying to the "Rocket Gods" and miracles, Erin believes in using skill to get what a person wants. Where Yuki tries to lift everyone spirits by being goofy, Erin tries to shut it down by being reasonable.
  • Go Out with a Smile: After her fight with Fourze she gives one...and then Virgo teleports her to Gamou so her memory will be erased.
  • Green-Eyed Monster: To make a long story short, she despises Yuki Jojima. More specifically, she hates Yuki Jojima due to the resemblance of a person who took her father's spot in going into space.
  • Hair-Trigger Temper: Anything that comes out of Yuki's mouth makes her panic and crazy; she goes overboard when she assumes Yuki hid the camera parts for the team's robot to make her look bad—the keyword being "assumes".
  • Healing Factor: Her water jugs on her shoulders can heal anything...even a Cosmic States Limit Break!
  • I Gave My Word: She made a promise to Gentaro that she'd give a fair fight to Yuki during the exams.
  • Laser-Guided Amnesia: Just like Goto prior, she has this too. However, the ending of #38 ends on a positive note with her excitably interacting with Gentaro and Yuki.
  • Making a Splash: Except her water gimmick acts as a Healing Factor, and she attacks with that nasty cat-o-nine-tails thingy.
  • Malaproper: She has a hard time pronouncing some Japanese sayings, such as proclaiming that she is "filthy" instead of "flawless" in Zodiarts formnote ; that's how Gentaro figured out Erin was Aquarius. It even goes to the point that the Zodiarts have to correct her pronunciation. Justified in that she is foreigner and Japanese is damn hard to learn as a second language.
  • Meaningful Name: Her name is an anagram of Eridanus, a mythical Greek river that is somewhat associated with Aquarius.
  • Monster of the Week: Just like Capricorn and Aries.
  • My God, What Have I Done?: Gentaro explains to Erin that Yuki did hide the camera parts because what she found in the box were instructions for the robot the team had to make. It was a Secret Test of Character to see what the team could do under circumstances, and Yuki created that cat to make up for the loss. Gentaro notes that by being the leader, Yuki would be downright hated by everyone else, but she was willing to do so for the sake of the team. And when Erin returns after pushing Yuki off of the hill, Yuki states that she should leave the girl behind and save herself. Damn.
  • Not So Different: Even though she won't admit it, she is actually similar to Yuki. Both wish to go to space, and both are determined to do the best of their abilities. It's just that their ways of leading (where Erin immediately takes charge and tells them what to do and Yuki just suggests something and presses on knowing that people will despise her for doing so) that are huge contrasts.
  • Pet the Dog:
    • The first thing she does as Aquarius? Use the water from her healing jugs to heal Kengo. Unfortunately, not only does it NOT take, but in #45 Kengo relapses worse than before.
    • Despite being cold to Yuki, she also praises at how Gentaro and Kengo have the potential to become astronauts.
  • Poor Communication Kills: Because she was so angry at Yuki, she never got a chance to ask why Yuki hid the camera parts until Gentaro revealed that it was all a Secret Test of Character.
  • Serious Business: Going into space and passing the mock space exam is very important to her, since her father never had a chance to go. Thus while she is nice to Gentaro and Kengo, she utterly despises Yuki because she doesn't believe the Genki Girl is taking the whole thing seriously.
  • Spell My Name with an "S": In Japanese, it's spelled as エリーヌ (long i sound, ends with nu), rather than the usual エリン (short i sound, ends with n).
  • Stone Wall: That Healing Factor of hers makes it near impossible for her to be defeated. But if you can destroy both the water jars on her shoulders at once (even one jar is enough to heal the other), she's done for.
  • Visual Pun: Aquarius is the water carrier. So naturally, she's got a great big pair of jugs, as in the jugs on her shoulders.
  • Whip It Good: The Nectar. Which has multiple heads.
  • Worthy Opponent: Considers Kengo and Gentaro these in the astronomy exam. Yuki, on the other hand, is the exact opposite.

Taurus/Yuuta Sugiura

The ninth member of the Horoscopes to appear, he is based off of Taurus, the Bull. He was present for the mock space exam, though he was later revealed to have the potential to become Taurus. An avid golf player, who forces people to sign contracts with him, and the loser is banned from interfering with the winner in any way. Seeing himself as a force that should not be defied, he has starting changing the rules at AGHS, forcing those who do not comply by contract.

  • The Ace: In addition to being one of the four to make it into the school space program, he also bests JK and Gentaro in their specialties of break-dancing and double dutch. Considering that he explicitly breaks the rules of physics during the competitions, it's logical to assume that the switch is helping him out somehow.
  • And I Must Scream: Unlike Capricorn and Aquarius, he got sucked into the Dark Nebula. While in Zodiarts form!
  • Beat Them at Their Own Game: What he did to Gentaro and JK.
  • Character Tics: Always playing mini-golf in his office.
  • Chekhov's Gunman: At first, he seems to have just been there for the exam. At the end of the episode, though, Libra reveals that Sugiura is going to be Taurus.
  • Deal with the Devil: Seems to be his MO when dealing with potential threats.
  • Even Evil Has Loved Ones: Apparently, he has a crush on the former student council president, and that is the real reason why he has gone so far off the deep end.
  • Expy: Of Yamada, the Aries Zodiarts. Both of them are control freaks that suffer from god complexes and use their newfound power to rule their school with an iron fist.
  • Eyepatch of Power: He has one in his Zodiarts form. Note: it's on his right.
  • A God Am I: Thanks to Hayami's manipulation, Sugiura has gained a god complex.
  • Meaningful Name: The syllables in his name can be rearranged into "Taurusu Gyu" (Gyu meaning "bull").
  • Mundane Utility: Gu-anna, the medium of his Mind Control powers, and also an excellent golf club.
  • My God, What Have I Done?: When confronted with the former School President, he finds that he can't actually steal her soul when he finds out she's deliberately breaking rules—wearing mismatched socks, uniform and having a barbecue on the school roof—and cries.
  • Mind Control: Not only does signing his contract make people lose all body function, but thanks to his Gu-anna, he can suck out their souls and put them under his control. He even goes as far as to brainwash Meteor!
  • A Nazi by Any Other Name: The mannerisms of his disciplinary committee should give you a clue. However, this is because Sugiura had sucked out their souls beforehand.
  • Sixth Ranger Traitor: Also like Aries, he has this role amongst the Horoscopes. While Aries didn't so much as betray them as he did just utterly screw around instead of doing anything productive, Taurus actually left the Horoscopes all together.
  • Staff of Authority: His Gu-anna.
  • Tyrant Takes the Helm: Has started using his new found powers as a Horoscopes to severely limit the individuality of AGHS (Which is ironically the exact opposite of what Gamou wants) by enforcing new rules on the school, including a new dress code.

Gemini/Dark Yuuki

Live Actor: Fumika Shimizu
Voice Actor: Hiromi Konno

The tenth Zodiarts to appear representing the constellation Gemini, the Twins. A dark aspect of Yuuki that was created when Libra and Leo forced her to use a Switch that separated their body. Due to this, both Dark and Light aspects have a 24 hour time limit to see which side will be the dominant side, while the other one fades away.

  • Aside Glance: Sje glances at the camera when she does an Evil Laugh.
  • Bread, Eggs, Milk, Squick: The pranks Gemini pulls on the Kamen Rider Club: tying up Ohsugi's suspenders to stretch it to its limit, spraying JK with a water hose, dumping flour on Shun, and finally, throwing Miu off a balcony.
  • Dark Chick: Truly embodies this trope compared to Aquarius and even Virgo.
  • Death Dealer: Wields exploding cards called, respectively, Lynceus the red cards and Idas the blue cards as weapons.
  • Doppelgänger Attack: Like its name suggests, it can make a duplicate of itself as its Supernova ability, that explodes.
  • Having a Blast: Uses cards that explode. Red ones instantly explode, Blue ones act similar to the Stamper Switch.
  • Meaningful Name: An alternate spelling of Yuuki Joujima in English (with a lot of liberties taken) is "Yuuki Jousima", which can be rearranged to say "I am Soujikyuu"; "Soujikyuu" is the name of the Gemini astrological sign (not the constellation, which is Futago-za) in Japanese.
  • Stealth Pun: a double-themed character whose secondary motif is a jester; a joker. Don't get it?
  • Villainous Breakdown: Gets one when Gentaro shows Yuuki her homemade Space Ticket and thus frees regular Yuuki from fading away.
  • White Mask of Doom: As Dark Yuuki...until spending enough time active causes her to occupy the real Yuuki's presence, represented by her acquiring the real Yuuki's face while forcing said White Mask onto her instead!

Pisces/Ran Kuroki

The eleventh and final Zodiarts that represents Pisces, the Fish. Ran Kuroki is a former school swimmer freshmen who was first mistrusting of her older classmates after an incident in the past, but changed her behavior after helping Gentaro save her friend Haru from being a Zodiarts; who she now regularly visits in the hospital. Was forced/willingly chose to use the Switch to save Hayami from Leo.

  • Apocalypse Maiden: As the last Horoscope, the Club now has to protect her as well as her Horoscope Switch. If what Libra said is true, failure will result in the destruction of Japan.
  • Dark Chick: Defied.
  • Empowered Badass Normal: Ran was a great swimmer and competent fighter even before becoming a Zodiarts, and managed to hold her own against Leo even after first transforming.
  • Lightning Bruiser: Her underground swimming abilities allow her to move quite fast, and she is capable of matching Leo in a fight.
  • Making a Splash: In addition to water-manipulation powers, Pisces can "swim" underground, as shown when fighting Leo.
  • Meaningful Name: In the only other stretch of the group, when literally translating her name into English, you get "unbarked lumber" for "kuroki" and "orchid" for "ran", which form the (again a stretch) acronym UO which is the Japanese word for fish, which is what Pisces is represented by.
  • Nice Job Breaking It, Hero!: It turns out that Libra and Leo were banking on Ran to transform and save the former from the latter, therefore bringing the last Horoscopes switch into existence.
  • Our Mermaids Are Different
  • Prongs of Poseidon: The clone of Pisces in the movie uses a Type-1, but the Pisces in the show never uses it.
  • The Load: In both arcs that she appears in, nearly all of Ran's decisions actively make the situation worse due to her rashness, violent tendencies, and smothering overprotectiveness towards Haru.
  • Token Good Teammate: Pressed her switch for entirely selfless reasons, and by far beats Capricorn, Taurus and Aquarius eventually for the position of least malevolent Zodiarts.

    Other Zodiarts 

Other Zodiarts

Toshiya Miura/Orion

Live Actor: Masanori Mizuno

A member of the football club who, fed up with his peers' poor treatment of him, accepts the Orion Switch to get revenge. His patron constellation is Orion the Hunter.

  • No Respect Guy: Gets told by Shun that he's going to be benched rather harshly. In Episode 8, Shun confesses this was due to his father telling him to do so, and he felt remorse when he saw how this took a toll in Miura's sanity.
  • The Power of Love: His love for Mari helps him overcome his addiction to the Orion Switch.

Tamae Sakuma/Chameleon

Live Actor: Maria Yoshikawa

A third-year and member of Miu's cheerleading trio, whose disillusionment with Miu's two-year winning streak at the Queen Festival drove her into accepting the Chameleon Switch. Her patron constellation is Chamaeleon the Chameleon.

  • Easily Forgiven: Miu forgives her for becoming Chameleon, and hopes to see her work hard when they run for the Queen Festival next year.
  • Jack-of-All-Stats: The stretchy tongue and invisibility give her a better edge than most Zodiarts, but not enough to outmatch Fourze's arsenal.

Fumihiro Nitta/Unicorn

Live Actor: Kiyotaka Uji

A first-year fencer who holds a deep grudge against JK for once using him as a human shield against a bunch of bullies, severely injuring his right arm and thus preventing him from competing in a fencing meet. Driven by vengeance, he accepts the Unicorn Switch. His patron constellation is Monoceros the Unicorn.

  • Cool Sword: Longsword Monarch.
  • False Friend: JK pretends to be friends with Nitta so that he can use him.
  • Game-Breaking Injury: Thanks to JK using him as a Human Shield, he got a bad injury on his right arm and thus was forced to miss out on a fencing tournament. This, coupled with him overhearing that he was simply used, fuels his hatred against JK. It's ultimately subverted as he's not only recovered, but well enough to augment the power of his Switch.
  • Human Shield: What JK made him to be in the past against a bunch of bullies. This fuels his rage against him.
  • Lightning Bruiser: Hard to hit, pretty speedy, and the rapier is pretty useful when regular attacks won't cut it.
  • Master Swordsman: Justified - the Switch evolved in reaction to his training in fencing.
  • Unicorn: Obviously.

Teruhiko Satake/Hound

Live Actor: Ryuji Sato

A second-year and son of the notoriously ruthless detention teacher, Takashi, who has decided to rebel against his strict father. Along the way he receives the Hound Switch, and soon goes on a rampage. His patron constellation is Canes Venatici, the Hunting Dogs.

  • Chain Pain: Both in human form (only for the symbolism though) and Zodiarts form.
  • Freudian Excuse: Conveniently mirroring Shun during Episodes 7-8.
  • Jack-of-All-Stats: His two attacks are great for long and mid-range opponents. Unfortunately, most of the time he is able to escape due to something else happening (ie Scorpio helping him or Shun stopping Fourze from defeating him). Once Fourze had him in the open, he was done.
  • Japanese Delinquents: At home, anyway.
  • Living a Double Life: JK's intel reveals that at school he plays The Dutiful Son and student; after school, however, he became a petty thief stealing chain-like jewelry, using them as his weapons and also to symbolize his desire to break free from his father's shadow.
  • Not So Different: He and Shun both have overbearing fathers; they only differ in actions - whereas Shun was driven into a breakdown but eventually found friends, Teruhiko decided to bust the chains out and act like a rebel.

Ritsuko Usaka/Altar

Live actor: Hikari Kajiwara

A leader of a witches' coven that comprises Yuri Kuramochi, Masami Okamura and herself. As Altar she uses her powers to make it appear that her group has magical powers. Her patron constellation is Ara the Altar.

  • Freudian Excuse: Reveals that she's already sick of being ostracized because she can see things others couldn't, and getting blamed by teachers for any supernatural mishap she witnesses.
  • Hoist by His Own Petard: Tries to beat Fourze using her head of fire...but his Fire States makes him able to absorb her attacks, thus rendering them useless.
  • Not So Different: With Tomoko - both have ESP, as shown in a flashback when they first meet, as both of them reach for the same book. The glaring difference between their fates gets lampshaded below.
  • Magic Staff: Aradia Staff which produce fire and have psychokinetic ability.
  • Mighty Glacier: Doesn't move a lot and uses her levitation to get an advantage on her opponents. Her fire attacks are very powerful though...until Fourze absorbed it and sent it back at her.
  • Pet the Dog: Despite her hatred of teachers, she liked Sonoda-sensei enough to be honest about how her presence could've saved her from the life of a witch and exhorts her to run away before she blows up the entire school. Becomes very hard to look at when you find out about what Sonada really is 3 episodes later.
  • Then Let Me Be Evil: Being treated like a freak and always being blamed for the supernatural occurences only she can see caused her to turn bad for real. She actually quotes this almost word for word.
  • Villainesses Want Heroes: When she returns, it turns out she wants to ask Gentaro to the prom. She had to settle with Ryusei instead in #26.
  • Wicked Witch: Or so the Altar Zodiarts' power allows her to.

Hiroki Makise/Pyxis

Live Actor: Takafumi Shinohara

Yuki's former "friend" at the Astronomy Club who has a massive crush on her. Uses his Zodiarts power as a way to get to her and then extract his revenge. His patron constellation is Pyxis the Mariner's Compass.

And all within the sophomore year! There's also the fact that he's a complete weakling in hand-to-hand combat, the only blows he ever manages to score on Fourze being a result of pretty much just flailing his bladed arms around like a dork, but his power of being able to move things with his mind make him a threat.
  • He only gets worse in the follow-up novel “Ama-High Graduation”, where he is part of a Fusion Dance to summon the Argo Zodiarts.
  • Blade Below the Shoulder: Averted. Despite the way they are place and look, Pyxis does not use them for offense.
  • The Bus Came Back: He comes back in #37.
  • Character Tic: Has a peculiar way of holding his switch, by sticking out his index finger as though he were pointing before clicking on the switch with his thumb, often holding his hand sideways as he does this. He holds the Radar switch like this in the movie when he switches it on.
  • Dirty Coward
  • Dowsing Device: How the blades on his arms function. They range from having the ability to find something (by letting someone touch them and think about the item in general), or using them to control people for his own use.
  • Explaining Your Power to the Enemy: He was smart enough to AVERT this; Fourze tried firing his Launcher missiles at Pyxis, not knowing of the latter's powers until it was too late, destroying what seemed to be the locker to the Rabbit Hatch in the process.
  • Failed a Spot Check: Yuki never even realized he was also participating in the test until they were all inside the Isolation Chamber. Naturally, she freaks out and backs away from him.
  • Four Eyes, Zero Soul: Was obsessed with Yuki for quite some time, but now that he's Pyxis he decides that it's time to crush her like (he thinks) she did to him, stating she was damaged goods. He's also the first Zodiarts to be portrayed as an unsympathetic Jerkass from the get go. What's more, he was like this before Scorpion gave him that switch!
  • He-Man Woman Hater: His stalker-like tendencies fueled this ideal. Tomoko lampshades this when he returns in #37—25 episodes later by saying, "Simply, he's a misogynist."
  • I Lied: Made a deal with Yuki to find the locker if she agreed to be his girlfriend and abandon her friends. He had no intention of keeping his side of the deal and instead blew up the locker so he could see her cry.
  • Jerkass: So much so that Gentaro doesn't extend his hand of friendship as he'd done with previous Zodiarts.
  • Kick the Dog: Only helped Yuki find the locker for the Rabbit Hatch just so he could destroy it and make her cry.
  • Knight of Cerebus: Of the Monster-Of-The-Week variety.
  • Laser-Guided Karma: Becomes the first Switcher to miss out on Gentaro's friendship offer, leaving him instead to try to flee (in vain) from the girls whom he trapped on the bus at the end of Episode 12.
  • Loners Are Freaks: He's the only member of the Astronomy Club (Yuki notes that it's because of his behavior that everyone left), and is shown to interact with no one else in the school. Oh and he's a stalker, that should explain everything.
  • Man Scorned: Yuki has no feelings for him whatsoever, so he made it his duty to crush her by trying to destroy the locker connecting to the Rabbit Hatch. Taken Up to Eleven in Episode 12 when he tries to murder every other girl who shot him down by trapping them on a bus bound to drive off an unfinished bridge.
  • Mind over Matter: Can control objects and people with the blades on his arms.
  • Never My Fault:
    • He seems completely oblivious to the fact Yuki isn't turning him down out of spite but out of repulsion over his creepy obsession with her, instead deciding that she deserves to suffer for it. This extends to the 20-30 other girls that have rejected him.
    • He also claims it's Fourze's fault for (apparently) destroying the locker to the Rabbit Hatch (when in fact he redirected Fourze's missiles).
  • Psychopathic Manchild: Let's see, a loony kid who obsesses over Yuki but then tries to destroy her once it became clear that she's not going to reciprocate his "feelings" and takes sheer delight in turning girls into shooting stars by killing them (as evidenced by a future diary full of cute pictures depicting his gambit to send a bus full of them crashing off of an unfinished bridge)? Oh, yes. And JK's intel implies he's been like this way before he even got his Switch!
  • Reformed, but Rejected: Only in his own mind (re: #37). Played straight in the movie, though, when he is chosen among the 40 people who will press the astro switches in order to create a new power to save Gentaro and Ryusei.
  • Slasher Smile: Has one of these whenever he's about to transform into Pyxis.
  • Squishy Wizard: He terrorizes Amanogawa with his telekinetic powers. The Zodiarts Switches' ability to mutate to suit their users' natural talents, however, leaves him in a bad spot. Whereas Miura was a football player, Sakuma a cheerleader, Nitta a fencer, Satake a brawler, and Usaka a firm believer in black magic, he's nothing but a geeky dork with serious psychological problems, leaving him an utter pushover in melee combat (one exploited by Fourze's mid-range-oriented Elek States).
  • Stalker Shrine: He wasn't only obsessed with Yuki. JK found out that the guy has a star map with the names and pictures of all the pretty girls in Amanogawa that he was gong to put on a bus and make it crash off of an unfinished highway.
  • Stalker with a Crush: For Yuki. He's given her incredible amounts of letters, gifts, emails and voicemails for God knows how long.
    • Apparently extends to a host of other girls whom he forced onto a bus headed for an unfinished bridge.
  • Teens Are Monsters: He's the worst out of all of the unevolved Zodiarts shown and that's saying something!
  • Vile Villain, Saccharine Show: In a rather lighthearted series where even Gamou seems to have good intentions and every other Zodiarts is an Anti-Villain, a genuinely creepy sociopath like this guy really stands out.

Soushi Motoyama/Perseus

Live Actor: Ryutarou Akimoto
President of the Art Club. He takes the Perseus Switch so he can dish out some punishment upon anyone (and anything) that disturbs his work. His patron constellation is Perseus.
  • Ax-Crazy: He was the second craziest Zodiarts next to Makise, but he's shown to be much better off at the end of Episode 16.
  • Berserk Button:
    • This guy really hates Yuki's voice when she sings, but has no problem with Abe and the rest of the Glee Club.
    • He also hated Gentaro singing the Hayabusa song (although Gentaro might've done it deliberately to lure him out)
  • Childhood Friends: Abe mentions that they went to Elementary and Middle School together. At the end of #16, they're on the rooftop shaking hands.
  • Disproportionate Retribution: He's decided to turn everyone who kept him from painting in peace into stone statues. His victims are three punks who bullied him, a pitcher who accidentally knocked over some paint cans with a stray baseball, and two Gossipy Hens who, in his opinion, won't shut up. And that's not yet mentioning a building he damaged such that it will lean, because it was blocking his view of Mount Fuji.
  • Freudian Excuse: Because everyone's been bugging him and not letting him paint in peace, he's become a Zodiarts to shut them up for good.
  • Hair-Trigger Temper: If you do anything to interrupt his painting, he'll go berserk.
  • Heel–Face Door-Slam: the first Zodiarts in the series to show redemption even in Last One stage, but Libra uses Mind Control on him to force him to fight Fourze.
  • Irony: His powers get blocked when Gentaro uses the Pen Switch on him and splatters ink on his Medusa Hand. It has been said that the pen is mightier than the sword...
  • Mad Artist: His art is decent, but his obsession to his works is... unhealthy, to say the least. He gets much better at the end of #16, deciding to redo his Mount Fuji picture and is shown to be more calm about it.
  • Manly Tears: Breaks down into these (While in Zodiarts form, mind you) once he sees the works of the kindergarten class surrounding a previous work of his, and realizing that he was only trying to make himself happy with trying to perfect his painting.
  • Master of None: Sure he has the sword and petrification powers, but he's nothing when they're rendered useless.
  • Medusa: His left hand turns people to stone. And if Gentaro was conscious the whole time... Kengo notes that the petrification wasn't complete and that's why Gentaro was able to move around despite becoming stone. Still, doesn't necessarily mean the other victims aren't somehow conscious despite being unable to move.
  • My God, What Have I Done?: Upon arriving at the kindergarten class, he's awed that his previous painting is surrounded by all of the other works of the kids, reminding him of Gentaro's drawing of Mount Fuji. He then realizes that he had taken his art so seriously that he forgot the reason he'd been making it in the first place, to make the children happy, breaking down into tears. It's also implied that this canceled out his ability to evolve into a Horoscope.
  • Pet the Dog: Yes, he's utterly crazy and has bad anger issues, but the reason he wants to perfect his paintings is because he simply wanted to make a kindergarten class he sometimes visits happy with his works. Also, he doesn't hate all of the Glee Club; his ire is just toward Yuki and her Hayabusa song. As shown in the end of #16, he's back to being good friends with Abe.
  • Secret Handshake: Shown twice; he does it with Gentaro (as Perseus) and then once more with Abe at the end.
  • Super OCD: He proclaims that anything that isn't perfect must be destroyed. Fortunately, he sees all of the kindergartners' drawings next to his old painting for them, and realizes that it doesn't matter if it's perfect or not. What mattered was the passion and love they put into them.
  • Taken for Granite: What frequently happens to his victims.

Kimio Nonomura/Lynx

Live Actor: Shohei Yamazaki
Kengo's self-proclaimed rival, who was given his Switch by Libra. He uses it in order to get rid of the competition of all students with higher test scores than he. His patron constellation is Lynx the Lynx.
  • Character Tics: Snapping his left thumb and index finger, which quickly outed his true identity to the Club.
  • Flat Character: Aside from having a one-sided rivalry with Kengo on the smartest student in school, there's nothing else on him. Even more so since we don't even see him after Gentaro destroys his Zodiarts switch.
  • Fragile Speedster: Uses his speed to his advantage, but can't take powerful hits.
  • Serious Business: He knocks out the competition for smartest student in the school.
  • Shadow Archetype: He's basically Kengo minus the idea of him wanting to make friends and the toleration for Gentaro's antics.
  • Small Name, Big Ego: It comes with being Kengo's "self-proclaimed" rival.
  • The Rival: Claims to be this for Kengo.
  • What Happened to the Mouse?: He was last seen in the Rabbit Hutch with the KRC suggesting to put him in a storage closet. We don't even know whether or not he changed for the better.
  • Wolverine Claws: Comes in hand with his feline theme.

Jin Nomoto/Dragon

Live Actor: Ryu Ando
Captain of the Track and Field team who became a Zodiarts to discourage outside help and to kill the Kamen Riders, starting to grow bored of track practice. His patron constellation happens to be Draco the Dragon.
  • Nigh Invulnerable: It can stand the attacks from both Fire and Elec states, and Meteor can't even land a single blow on it! The "Nigh" comes into play when Fourze assumed Magnet States, then mopped the floor with Jin.
  • No Social Skills: Shun notes that Jin's "not good with words" when he returns, implying this played into Jin's Zodiart stint.

Natsuji Kijima/Pegasus

Live Actor: Soran Tamoto
A Zodiarts who is attacking talented martial artists to test its own strength. Its patron constellation is Pegasus until he evolves into Cancer.
  • Beneath the Mask: A very jolly fellow who sprinkles rakugo phrases and puns into his normal speech. Then after he is uncovered as Pegasus, he drops the flowery speech and becomes sinister and cold.
  • Character Tic: Clops his feet like a horse when about to throw a high kick. He only does this in order to incriminate Haruka Utsugi, and drops it once he is uncovered.
    • Nowadays he's more often seen tapping that fan of his in time with the dialogue.
  • Disproportionate Retribution: Part of the reason why he framed Haruka Utsugi was because she took away his fan when he accidentally hit her with it, though he admits he would've done it to someone anyway and that was just why he did it the way he did.
  • For the Evulz: Outright admits most of his reason for becoming a Zodiarts and framing Haruka was simply because he enjoyed it. Pretty much becomes his modus operandi when handing out Zodiarts Switches.
  • Frameup: Tries to frame Utsugi by mimicking her fighting style, dropping some evidence and telling the KRC that she took it from him, and outright saying "Do you really want to hit your teacher?" when Gentaro fights him in Episode 21.
  • From Nobody to Nightmare: Found his switch by complete accident (rather than being selected by the Horoscopes) and still manages to be the first Monster of the Week to evolve into a full blown Horoscope.
  • Meaningful Name: His given name can be alternately read as the word for "crab".
  • One-Winged Angel: Transforms into Cancer.
  • Pegasus: Self explanatory.
  • Pungeon Master: A member of the school's Rakugo Club, he often mixes puns and wordplay into his speech. Especially obvious in Episode 27, when he spends a couple of minutes during his fight with Meteor making puns about fish and tadpoles, to Meteor's growing annoyance.
  • Red Herring: Was thought to be Haruka. He was deliberately impersonating her fighting style to set her up as said Zodiarts out of petty revenge for confiscating his fan, and For the Evulz.
  • Shadow Archetype: He's pretty much Ryusei without something to keep him good - both put up a Nice Guy facade to hide their more serious personae. Whereas Ryusei ultimately Took a Level in Kindness, Natsuji is rapidly Jumping Off the Slippery Slope and into a full Horoscopes.
  • The Sociopath: What he's like Beneath the Mask.

Norio Eguchi/Cygnus

Live Actor: Shugo Nagashima
Voice Actor: Taiki Matsuno
A student who wishes to be a hero after observing Fourze. He becomes a Zodiarts who styles itself as a Hero of Justice, complete with flashy entrance and catchphrase. However, it possesses a fragile ego and spitefully assaults anyone who slights it and even more so. Its patron constellation is Cygnus the Swan.
  • Bitch in Sheep's Clothing: Zig-zagged. At first it seems like a hero for justice...until JK reveals that Cygnus beats people up who make fun of it. Misa Toriizaki was the suspect, but when it turned out to be Eguchi, he was revealed to have a split personality, where his darker side was the one beating people up including (mentally) Eguchi for not living up to his standards. By the time he resisted going the Last One Stage, however, he get abducted and the previous Red Herring lead her group into forcing him to transform!
  • Captain Ersatz: Of both Sieg and Kamen Rider IXA.
  • Character Tics: Assigning people points based off of good or bad actions; Cygnus fangirl Misa Toriizaki does the same but this is just a Red Herring.
  • Cosplay: Has an outfit inspired by Cygnus, and then dons one based on Fourze at the end.
  • Dirty Coward: The darker personality used Tomoko as a shield to keep Meteor from bashing him in. He does it again in Episode 24, this time with Toriizaki.
  • Everyone Calls Him "Barkeep": Due to his reputation as a hero, everyone simply calls him "Cygnus"; Gentaro's fight with his Last One state in Episode 24 marks the first time anyone refers to him as the Cygnus Zodiarts.
  • Feather Flechettes
  • Fanboy: Wanted to become a hero after observing Fourze fighting off Lynx in Episode 18 then switched to Cygnus after he was saved from thugs. He decides to go back to worshiping Fourze via dressing up like him and helping a lady on the street.
  • Glass Cannon: Can beat up people with a fight and uses his feathers as projectiles, but once Meteor gives him a good kick, he goes down.
  • Lady Macbeth: Became a victim of one, by Toriizaki just as his switch reached the Last One Stage.
  • Paint It Black: His Perpetual Molt does this once he triggers Last One.
  • Perpetual Molt: The indication that Cygnus has arrived.
  • Secret Test of Character: Gentaro gets the members of the KRC to dress up and act out in situations to let Eguchi help them out. Eguchi settles on helping the little school kid (aka Yuki) get her balloon back.
  • Split Personality: The first time Eguchi used the Zodiarts Switch, it caused the darker side of his personality taking control of Cygnus while the real guy remained oblivious.

Yayoi Tokuda/Coma

Live Actress: Kasumi Suzuki
A third-year who is head of the Newspaper Club. She becomes a Zodiarts who uses its hair to create copies of the Chameleon, Altar and Dragon Zodiarts in order to frame their original Switchers and prevent them from graduating. Its patron constellation is Coma Berenices, the hair of Queen Berenice II of Egypt.
  • Bitch in Sheep's Clothing: Seems to be a reasonable reporter...then she intentionally frames Tamae, Kimio and Ritsuko of wrongs they never committed — all because she doesn't want to graduate and neither will she let the others do so.
  • Foreshadowing: What's she doing in her first appearance? Trying to get an article out of Tamae, Ritsuko and Jin, even though it's only Ritsuko's alter-ego who "returned" around that time.
  • Four Eyes, Zero Soul
  • Growing Up Sucks: Her motivation for becoming a Zodiarts and framing Ritsuko, Kimio and Tamae? She doesn't want to leave high school, and feels that neither should everybody else.
  • Hypocrite: Becomes a monster because she loves AGHS and doesn't want to graduate. Yet she furiously claims Tamae, Jin, and Ritsuko don't deserve to leave after their actions as Zodiarts, apparently seeing AGHS as a punishment as well.
  • Informed Ability: JK claims that she makes for a better Knowledge Broker than him. At the very least, she was able to figure the identities of former monsters.
  • Mook Maker: Can turn its hair into copies of existing Zodiarts.
  • Not So Different: To Miu. Both are seniors, presidents of their respective clubs, and dread graduating. However, this is where similarities end: whereas Miu learns to accept the fact but Yayoi refuses to accept it.
  • Prehensile Hair
  • Squishy Wizard: She can create clones from her hair and use it to entrap opponents, but once she's rendered immobile by the Power Dizer, she's pretty much good as done.
  • Stringy-Haired Ghost Girl: Provides the inspiration for this Zodiarts. Not just for the stringy hair and deliberately creepy Limp and Livid portrayal, but Yayoi also harbors a grudge.
  • What Happened to the Mouse?: We don't know if she even graduates or gets held back like she wanted to.

Haru Kusao/Musca

Live Actor: Jigen Araki
A freshman who was given his Switch by Libra in an attempt to be more outgoing. His patron constellation is Musca, the Fly.
  • Berserk Button: Due to the Switch, he lashes out at Ran on her insistence on always trying to protect him or whenever she utters her Catchphrase "I'll protect you Haru!".
  • Lethal Joke Character: Considering that he starts out as a wimp, and gets a simplistic Zodiarts design that's little more than a glorified Mook with a pathetic housefly Animal Motif, his sudden rush of powers really comes out of nowhere.
  • Only Friend: Ran is his only friend even though he actually wants to be friends with Gentaro. Ran is pretty much the sole reason that Haru even became a Zodiarts in the first place and ironically the reason that he gets worse.
  • Power Gives You Wings: Once he reach Last One.
  • Protectorate: Deconstructed in that his desire to change is ousted by his overprotective friend, frustrating him.
  • Shrinking Violet: Doesn't help that he has a pushy girl friend like Ran.
  • The Sixth Ranger: At the finale, Haru finally becomes a member of the Kamen Rider Club with Ran.
  • Took a Level in Badass: Is noteworthy in that his Switch is evolving even before Last One.
  • Unfortunate Names: Kusao may have been derived from 'kuso', a word with disgusting connotationsnote , as if hammering home his loser image...or foreshadowing the whole housefly thing.


How well does it match the trope?
