Once the savior of Amanogawa High, he died at the hands of Ryusei Sakuta in a Deal with the Devil with Yamada Tatsumori/Aries Zodiarts. He was resurrected by Ophiuchus and is now his Serpent-bearer, hell bent on destroying those who stand in his master's way. In "Tears to Shed" he struggles to become the Serpent-bearer needed by his master and in "Birthday Massacre", he is constantly bombarded by different fragments of himself who beg him to escape Ophiuchus's wrath. In SplitxEnd there are hints that there is more than meets the eye about him.
Ancestral Weapon: Has access to the Scepter of Asclepius whenever he uses Void States or taps into the power of the White Crow of the Veil. Justified in that he's a descendant of the original Asclepius.
Et Tu, Brute?: Thanks to Ophiuchus brainwashing him into believing that the Kamen Rider Club left him to die and showed him a warped vision of everyone blaming each other. Doesn't help that Ophiuchus is (somewhat) correct in that matter.
Even Evil Has Loved Ones: Still loves his parents as the first chapter of Tears to Shed sees him at their graves. Until Tears-10 where he leaves them behind to follow Ophiuchus.
Hates Being Alone: Despite not wanting friendship, he notes that he doesn't want to be left all by himself. His reasoning, aside from It Amused Me in Tears-6 is that he wants people to talk to, not brainwashed slaves.
Hidden Depths: SplitxEnd, Tears to Shed and The Birthday Massacre reveals that he's a descendant of Asclepius and the current bearer of the White Crow of the Veil.
I See Dead People: Yayoi finds out that he has this ability, explaining how he obtained those "thousand friends" prior to coming to Amanogawa High.
It Amused Me: Why did he make Kengo and Jiro in some sort of psychotic relationship? To ease boredom.
Light is Good/Light Is Not Good: He's the White Crow of the Veil, a good spirit to send the souls to the afterlife by being friends. Unfortunately he's now the enemy, brainwashed by Ophiuchus.
Man in White: Remember, Japanese consider white just like Americans consider black: a color of death.
[Locked into Strangeness: Wajima states that descendants of Asclepius had white hair and they turn black at a certain age or during a traumatic experience. Yayoi reads his diary to find out that it happened after his parents' death.
More than Mind Control: Ophiuchus played specifically on how the Kamen Rider Club watched him die and stated that they let him die because if they were truly his friends, wouldn't they have stopped Ryusei from killing him?
Mystical White Hair: All descendants of Asclepius has this as a symbol of the White Crow's failure to obey Apollo.
Western Zodiac: He's an Ophiuchus in this story. Interesting to note is that Japan uses the system where Ophiuchus is a member of the Zodiac. Part of the mystery is uncovering why Ophiuchus is/is not a Zodiac sign.
Woobie, Destroyer of Worlds: Really, if it wasn't for the fact that Ophiuchus is brainwashing him, you'd be giving this guy a hug for the crap he's going through.
Would Kill A Girl: He doesn't give two shits about getting Misa Toriizaki or Yukina Takamura killed, and he certainly has no qualms about fighting Erin and Yuki after crushing their Zodiarts switches and absorbing their powers.
Once an ally to the Kamen Rider Club, he made a deal with Yamada Tatsumori that ended with Gentaro's death. Unfortunately, it didn'tend well. As a result of his actions, the Kamen Rider Club can no longer trust him, and Tachibana has taken desperate measures to ensure that things go right this time. As of XVIII-Theater of Tragedy, he's been transformed into a cyborg.In Who Decides?, he meets with Madame Pollux in regards to Jiro's fate. The fortune just leads him to kill Gentaro in the end.
The Atoner: He wants to be this, honestly. Too bad Tachibana won't give him that.
Ax-Crazy: Tachibana gave him Cosmic Energy injections that made his mind unstable which ended with him killing Shun in XI-Team Spirit.
Fun with Acronyms: As of XVIII-Theater of Tragedy, his right arm has the words Machine Engine Terminal-Entity Of Rancour tattooed.
Hero Killer: Aside from killing Gentaro, he also was the cause of Shun's death.
Hidden Depths: Tachibana states he's a Core Child, but that was probably a ruse for something else.
My God, What Have I Done?: When he saw Gentaro resurrected, his look says it all. This is also shown in Why Decide? when he realizes that by deciding his fate so early on, he never realized the consequences of following it to the end.
Nice Job Breaking It, Hero: All of the stuff wouldn't have happened if he didn't kill Gentaro, or at least realize that killing Gentaro wasn't the way to go.
Tarot Motifs: In Who Decides? his future card is the upright Nine of Rods, telling of how he must keep in pursuit of his goal despite obstacles in his way. In the extra short, Why Decide his card is the inverse Nine of Rods stating that his pursuit to make things right will pretty much end badly.
Walking Spoiler: After III Genesis, everything about Ryusei pretty much goes downhill.
We Can Rebuild Him: After having Gun Den-O use his Full Charge, Tachibana resorts to this since the attack nearly killed him, becoming a cyborg.
Western Zodiac: He's born on June 6th in the story, making him a Gemini.
Kamen Rider Club
The Kamen Rider Club is Amanogawa High's defense against the Zodiarts. With Gentaro gone, they have decided to continue his work in befriending everyone and stopping the school's chairman from accomplishing his goal while struggling with the idea that they will eventually have to kill their close friend.
Yuki - Brains, being an Otaku with lots of knowledge regarding space
Miu - Brawn, the leader of the Kamen Rider Club piloting the Power Dizer.
I Let Gwen Stacy Die/It's All My Fault/My Greatest Failure: The Kamen Rider Club blame themselves for Gentaro's death with each of them spouting off different reasons (Ranging from Tomoko not figuring out Ryusei's identity quicker, JK not doing a background check on Ryusei, Shun berating himself for not separating the fight, Yuki only yelling "Stop!" but not actually moving, etc.) as to why he's dead.
Plucky Girl: Despite the trauma and horror, the girls are more than ready to kick ass.
Hidden Depths: She took gymnastics in order to get used to the gravity in outer space.
Name's the Same: With Yuki "Riderman" Joji. To make it less confusing, she gets called Yuki.
Never Live It Down: In-universe. The antagonists love to rub it in her face that she just yelled "Stop!" when Ryusei was about to kill Gentaro and she hates herself more because of it.
Power Fist: She utilizes her Hayabusa plushie this way thanks to Nadeshiko placing SOLU over it.
"The Reason You Suck" Speech: Instead of cowering in front of Yukina, she stands her ground to tell Yukina that her attitude would not make her be on Gentaro's good graces. Unfortunately, she gets slapped for her troubles.
The Team Normal: Of the original Kamen Rider Club members, she doesn't have a supernatural power. This is in contrast with Gentaro, Shun and (possibly) JK being Serpent-bearers, Kengo being a Serpent Vessel, Yuki being Gemini Zodiarts and Tomoko's strange psychic powers.
JK/Kamen Rider Den-O: Gun Form (Ryutaros)
The gossip broker of the Kamen Rider Club, JK decides to not run away and fight against this madness. With Ryutaros, he can become Kamen Rider Den-O: Gun Form.There are hints throughout the story that JK's hiding some sort of dark secret. In SplitxEnd, Yayoi refers to it as "that incident" which relates to his father retiring from his rockstar career. Things get worse when he is forced to obtain a contract with a Serpent.
Dark and Troubled Past: "That incident", which his father states that it wasn't his fault about. After many hints from both Horseshoes and Hand Grenades and SplitxEnd, it's revealed that he had a little sister who died trying to protect him.
The muscle of the Kamen Rider Club who decides to take matters into his own hands. He passed his position as Power Dizer pilot to Miu and can become Kamen Rider Den-O: Rod Form with Urataros. Unfortunately, this did not make him immune to death, as he was killed by Ryusei in XI-Team Spirit, only to somehow gain a contract with Vasuki, the Tethering Serpent and become a Serpent-bearer himself.
Deal with the Devil: Somehow gained a contract with Vasuki that brought him back to life. Unfortunately, once Ophiuchus is defeated, Shun becomes Shiva's avatar and will live until it is Shiva's turn to destroy the world. Miu wasn't happy when she heard that part.
Dual Wielding: Wields two patas (a gauntlet with a blade fused on top) when Vasuki takes over.
Resident Perky Goth of the Kamen Rider Club, who has decided to no longer focus on Ryusei Sakuta and dedicate herself to stopping Ophiuchus. While excited to know that Kamen Riders do exist and that many of them are lending aid against the upcoming threat, she must also step into the fray with the Defenders of Justice.Her weapon becomes her white snake skin that can stretch to very far lengths thanks to Nadeshiko covering it with SOLU.
Barrier Warrior: Creates barriers similar to ones Gwen uses. How she obtained this power is unknown though.
The Faculty Adviser of the Kamen Rider Club, he now leads the fray against the Zodiarts under the vow that "Teachers protect their students". While not the strongest, his newfound courage has made him stand up against many of the supernatural threats that threaten to destroy the world.
Badass: He's one of the last people you'd expect to start kicking ass.
Badass Teacher: To sum up what's happen to him, he's stood his ground toward a bloodied Ryusei—who recently killed Shun—gets sent to the Dark Nebula with a smile on his face—saved Sonada and Kijima from the M-BUS satellite, freed Kengo from mind control while Kengo was choking him to death with flaming hands, and gave Sonada a Shut Up, Hannibal! speech while defeating her with both a slipper and a costume glove. After that, he confronts Sagittarius Zodiarts, hits him with a shoe, declares that he'll become the new principal of Amaongawa High and gains a caduceus that he immediately uses to whack the chairman across the head.
Guile Hero: Will say just the right words to push his enemies' buttons.
Improbable Weapon User: Defeats Sonada with a SOLU-enhanced costume glove (which is from Tomoko's cosplay of Kamen Rider Amazon), and a slipper. He utilizies his shoes against Sagittarius Zodiarts in Month of Sundays.
Love Makes You Stupid: He realizes that his love for Sonada blinded him to what was really going on. Ditching this made him a much more competent teacher.
Rousing Speech: His speech in IV-Shockwave was what made the Kamen Rider Club stop beating themselves up.
Rummage Sale Reject: The "armor" he uses on Day 2 of the Kyoto Trip is based off of the cosplays the Kamen Rider Club made of the Legendary 7 Kamen Riders. Notably, he has either Kengo or Shun's slipper based armor, Tomoko's finned costume glove, JK's metal bowl helmet, and Yuki's hook hand.
Shut Up, Hannibal!: Gives one to Sonada in regards to him being a loser. He does it to Sagittarius Zodiarts later by tossing his shoe at him.
Simple Staff: Starts wielding a caduceus after obtaining his will to fight.
Teleporters and Transporters: Obtains a Liner Pass that so far has let him teleport himself from his current position to the Rabbit Hatch. He exploits this by getting Virgo Zodiarts to teleport him to the Dark Nebula then rescue both Sonada and Kijima from stasis and then bring them back to Amanogawa High.
It's explained in Sundays-9 that those chosen to become members of the Cult of Caduceus will be able to go to places close to his heart. What better place than the one where he decided to gain his Character Development?
Weak, but Skilled: He's a regular geography teacher who, at the time of the Kyoto Arc, had only ONE day of kickboxing training. However, he's becoming a Guile Hero and his determination to help his fellow students has made him able to withstand attacks that would probably have killed him by now.
"World of Cardboard" Speech: He gives one to Sagittarius Zodiarts, eventually declaring that he'll become the new principal of Amanogawa High.
The defenders of justice, a few Kamen Riders have appeared to help aid the plight against Gentaro and Ophiuchus.
Badass: They're Kamen Riders—of course they're badass!
Ragtag Bunch of Misfits: The Den-O Kamen Riders consist of a painter (and former Zodiarts), the leader of a group of delinquents, a fanboy of superheroes (and former Zodiarts), an Information Broker with a fondness of break-dancing, and a former jock and mecha pilot.
Daisuke Yamamoto/Kamen Rider Amazon
The Kamen Rider from the Amazon Jungle, Daisuke gets involved when he finds the Clear Drill Switch crash land in the Amazon Rainforest. When he learns about Gentaro's dark resurrection, he wishes to befriend Gentaro and hand him the Clear Drill Switch.
Berserk Button: Like in his home series, hurting kids in front of him will invoke his wrath.
Super Mode: Somehow gains one by absorbing so much Cosmic Energy, dyeing his armor purple. Unfortunately, it doesn't last very long and leaves him a bit exhausted once it's finished.
The first Anti-Hero Kamen Rider, Joji is invited to the DenLiner and wishes to help Gentaro realize the error of his ways. He has recently received an upgrade that gives him it the Rocket Drill Arm from the Clear Drill Switch.
Badass Normal: Out of all the other Kamen Riders seeing as the only things he uses to fight are his Cassette Arms and his brain. Unfortunately, this also means he can't heal as quickly as his fellow Kamen Riders or Amazon.
Combat Pragmatist: Chucks a large rock at Libra Zodiarts before whipping out the Machine Gun Arm to his face.
Mythology Gag: The scene where he drills into the underbelly of Cancer Zodiarts or rather Tatsugami who somehow is in possession of the Cancer Switch and riddles the hole with bullets is actually from a scene in the Kamen Rider Spirits Manga where he did the same thing. He was also picked up in Polynesia, which is where he supposedly washed up after sacrificing himself to the Pluton rocket.
Name's the Same: To Yuki Jojima. The story refers to him as 'Joji' to lessen confusion.
Swiss-Army Weapon: His Cassette Arms. Unfortunately they get reduced to slag by Philip, but he now has access to a Rocket Drill Arm.
Kamen Rider Den-O: Sword Form (Momotaros + Souichi Motoyama)
Souichi Motoyama, once known as the Perseus Zodiarts, was unfortunately possessed by Momotaros while painting one day. After learning about the situation from Owner, and with some kind words from Tomoko, he decides to fight and end Gentaro's suffering.
The Atoner: Motoyama becomes Sword Den-O to forgive himself for becoming a Zodiarts.
Awesome by Analysis: Since he's an artist, Motoyama can easily tell how Philip holds his pen and the type of strokes that is used by how he holds it.
Real Men Do Art: Motoyama is shown drawing or painting whenever the group is relaxing, Momotaros doesn't think it's all that, though. When he finds one of the broken pillars, instead of taking a picture on his cellphone, Motoyama does a charcoal rubbing since it looks magnificent.
Kamen Rider Den-O: Axe Form (Kintaros + Ban Chosuke)
Ban Chosuke is the leader of the delinquents who was hijacked by Kintaros. At first, he didn't want to be involved with the madness until Tomoko convinced him otherwise. Ban's willingness to help caused Kintaros to cry Manly Tears in response.
Kamen Rider Den-O: Wing Form (Sieg + Norio Eguchi)
Norio Eguchi, the previous Cygnus Zodiarts, was introduced by Sieg to help fight against Gentaro. He immediately accepts so he can be a true hero. His main goal is to free Gentaro from the darkness inside his heart.
Ascended Fanboy: Norio wanted to be a hero during the Cygnus Arc and was last seen in a Kamen Rider Fourze cosplay. In this story, he's now a true Kamen Rider.
Curb-Stomp Battle: On the receiving end of one with Gentaro in Horseshoes-8. If it wasn't for Sieg, his head would've been cleaved off by a chainsaw.
Made of Iron: Subverted, when he arrives to join the Kamen Rider Club on their trip to Kyoto, Norio is commented on looking like he went to battle.
My God, What Have I Done?: Norio's reaction as to what happened when he became Cygnus Zodiarts and his initial meeting with Misa that thus became the creation of the Ugly Ducklings cult and everything else that went after that.
Odd Couple: Aloof princely Sieg and the heroic-wannabe Norio.
Haruka Utsugi/Kamen Rider Den-O: Super Climax Form
Replacing Sonada's role as the teacher of class 2-A, Haruka becomes informed of the situation in Amanogawa High by Ohsugi. After learning of Gentaro's plight, she hops on the DenLiner to aid the group in Kyoto.
Kick Chick: Uses her signature horse kick when necessary.
Team Mom: Gets saddled with the Imagins during part 2 of the Kyoto Arc and has a small scene where she keeps an eye on them.
Nadeshiko Misaki/Kamen Rider Nadeshiko
That's right, Nadeshiko from MEGAMAX returns to save Gentaro. After crash-landing on the Moon and becoming SOLU, she then comes to save JK before kicking ass once more.
Adaptational Badass: While Nadeshiko was only shown using the Rocket Switch, she's capable of all of the Right and Left Arm switches. This means that she can now transform into the Elec, Fire and Magnet States.
A new group of Amanogawa Students and teacher, who become involved in their own affairs in the Kyoto Arc. Their main story is A Month of Sundays where they must stop Foundation X, Gamou and another Serpent from causing even more chaos.
Tropes associated with the Cosmic Hunting Dogs
Badass Crew: They're slowly evolving into this, considering that they beat up previous Zodiarts (in human form but with their powers intact), helped Ohsugi fight Sagittarius Nova, and convince Damballa to work for them
The Glee has Abe being the fast one with his sword and blinds opponents with powder (Thief), Ibuki being a Ninja and more tools at his disposal (Mage) and Taira using an axe to deal the most damage (Fighter).
The female members has Rumi charging ahead with the vaulting pole (Fighter), Mari and her healing powers (Mage), and Jun's acrobatics (Thief)
Freudian Trio: The female side has Rumi the Id, Jun the Ego and Mari the Superego. The Glee Club has Ibuki the Id, Abe the Ego and Taira the Superego.
Nice, Mean and In-between: Ibuki the nice one, Taira the mean one (or at least more snarky than his fellow Glee Club members), and Abe being a nice guy but also gets into chats with Taira.
Master Character Heroes: Abe is The Protector, Ibuki is the Businessman, Taira is the Recluse, Teruhiko is The Male Messiah. When Miura is added, he also is The Protector.
Master Character Heroines: Mari is The Matriarch, Rumi is The Amazon, and Jun fills both The Nurturer and The Female Messiah.
Ragtag Bunch of Misfits: A photographer who likes photographing smiles, a High School glee club that has a sword wielder, ninja and samurai, a cheerleader who loves sweets, a Huge Schoolgirl who uses a vaulting pole, a Detention Teacher who previously had a habit of saying "Bad Boy" and his once delinquent son and former Zodiarts. They also recently added another former Zodiarts and current Horoscope Zodiarts.
Romance Genre Heroes: Abe is The Best Friend, Ibuki is The Professor, Taira is The Warrior, Teruhiko is The Swashbuckler and Miura is The Lost Soul.
Romance Genre Heroines: Mari is The Spunky Kid, Rumi is The Crusader and Jun fills the role of The Nurturer (with shades of The Free Spirit).
Member of the photography club, and girlfriend to Toshiya Miura, Mari is one of the more reluctant members of the Cosmic Hunting Dogs. However, she steps into the fray after invoking a deal with the Rainbow Serpent to heal her friends. She now aims to save Miura from Gamou's Mind Control.
Kaleidoscope Eyes: Her eyes glow yellow and orange when she activates "Sun Sight", which helps her see what a person truly desires. For example, when she analyzes Eiji, she sees that he wants the Taka Core Medal fixed.
The Power of Love: Uses this to free Miura from Gamou's brainwashing spell. It works.
Whip It Good: Can use bands of light as these, mostly to grab items from far away.
Club President of the Glee Club and good friends with Soushi Motoyama, Abe joins the fray and brings the other Glee Club members with him.
A Handful for an Eye: The scabbard of his blade has powder that he can use to blind people. Apparently, this is how he and Taira befriended each other in Kindergarten. He also picked up old spice jars from his house for future battles.
When All You Have Is a Hammer: Her main method of attacking is charging to the enemy, slamming the vaulting pole down, use momentum to leap into the air, and then kick a person in the face. Has been pretty effective so far.
Wrecked Weapon: Her vaulting pole gets snapped in half by Sagittarius Nova.
President of the Cheerleading Club who joins presumably under Miu's jurisdiction. While still having her love of sweets, she's determined to focus on stopping evil from spreading.
A Birthday, Not a Break: The day A Month of Sundays takes place (April 29th, 2012) is on her birthday. Subverted in that she knows, but she just didn't tell anyone about it.
Badass Normal: Doesn't have Rumi's vaulting pole, isn't a ninja or samurai like the Glee Club Members, carries no Zodiarts Powers and she's not a Serpent-bearer. She doesn't need any of these things to kick ass.
Batter Up: Picks up a baseball bat from her home. It's her younger brother's.
Beware the Nice Ones: She's the emotional center for the group, and is more excited about cake and being happy and cheerful. Then she effortlessly punches Damballa—as Kamen Rider Pierrot—and gets him to stop his fights all while giving him three powerful Armor Piercing Questions.
The Chick/The Heart: Is the emotional center of the group, comforting others with kind words.
Running Gag: Tries to call Miu about what's going on. Unfortunately, Miu is always in some sort of pickle whenever that happens.
Smarter Than You Look: She knows the symbolism of Mardi Gras colors and also about King's Cake (Although it's probably because it's cake that she knows it).
She shows her smarts in Sundays-11 when she's the only one to accurately explain Damballa's reasoning throughout the whole "Carnival of the Human Spirit" act he created and how it actually connects with the Mardi Gras color symbolism. Last, she gives three powerful Armor Piercing Questions to Damballa that make him go through a Villainous Breakdown. Lampshaded by Taira who stated that he was never going to "under-estimate the cake eating cheerleader again".
Stepford Smiler: Type A, surprisingly. She's actually hurting from the fact that her dad and little brother died ten years ago on her birthday—which is the day that Month of Sundays takes place. Explains why she doesn't want anymore bloodshed "today".
Sweet Tooth: Was ecstatic to try out the cakes Kougami has made and usually has a lollipop in her mouth. This aspect of her is what makes her befriend Quetzie.
She's also the only member of the Cosmic Hunting Dogs who really wants to try out Deneb's homemade lollipops.
The former Hound Zodiarts and son of Takashi Satake, Teruhiko wishes to fight against the monsters who made him lash out as the Hound in the first place. He was taken away by Foundation X scientists and experimented on, giving him the abilities of the Hound Zodiarts without pressing a switch.
Big Eater: Is on his third bowl of curry in the Cous Coussier when he gets the call from his father in Sundays-8.5. Justified in that he hadn't eaten anything when he was being experimented on.
Damsel out of Distress: A male variation. When he got captured by Foundation X, he freed himself with nothing more than his determination and willpower.
Determinator: Took Cosmic Energy injections for a whole night without screaming. Then, he goes out to fight the other Switchers that were kidnapped before trying to stop a werewolf morphed Eiji and getting involved with more Serpent madness with Ankh. We should also mention that he hasn't eaten or slept since then.
Synthetic Plague: Somewhat. He somehow gained the ability to have Cosmic Energy leak out of him, somehow transforming three Cell Medals into a new set of canine based Core Medals that forced themselves onto Eiji to give him a new form, and also give Ankh a new body. He presumes that he has it because he was in the midst of another Cosmic Energy injection and didn't complete it.
The proclaimed "hard-boiled" detective and prodigy of Souichi Narumi, Shotaro was relaxing in his office one day when Gentaro appeared. In a span of a few minutes, he finds out that "Gentaro" was a double and he also met up with Ophiuchus who brainwashed Philip and commanded him to kill his partner and succeeded. He was then revived by Damballa, transforming his body into a wooden puppet. Things have gotten worse in Month of Sundays as he's apparently given in to the serpent's chaotic nature. He can also transform into Kamen Rider Pierrot through Damballa's influence.
Shout-Out: Doll!Shotaro's nail teeth are presumably a shout out to a Junji Ito character named Soichi after the titular Soichi's Diary of Delights. Shotaro lampshades this as he tells Damballa that he isn't a 'demented manga character'.
Theme Naming: Kamen Rider Pierrot's special moveset includes:
Musical Theme Naming: Purple Rain (by the Artist formerly known as Prince), Greensleeves and Goldfinger (by Shirley Bassey)
Daughter of Souchi Narumi and wife to Ryu Terui, after hearing what happened to both Shotaro and Philip, she's decided to join the fighting, especially when she is now granted the power to be Kamen Rider Skull.
Shoe Slap: Her famous green slipper makes a return.
Take Up My Sword: Shotaro wrote her a letter that stated that should he or Philip (or in the worst case scenario, both of them) were incapacitated, she would have to be Kamen Rider Skull to save Futo. She agrees.
Ryu Terui/Kamen Rider Accel
Police officer of Futo who gets involved in the whole madness following Shotaro's death and resurrection.
Debuting in Sundays-5, there are two subplots regarding them: Kougami and Satonaka giving out information regarding Ophiuchus's origins and Eiji and Ankh returning to Japan with some...minor complications.
Eiji Hino/Kamen Rider OOO
While traveling through the desert, Eiji sees Ankh in his ghostly form and learns of the complications in Japan. Unfortunately, on his way back, he ran into Teruhiko and gained a new set of Core Medals that transformed him into a new Oyokal form. After he was freed from that, Shotaro kidnapped him and Damballa transformed him into a doll.
And I Must Scream: His transformation into a doll had his face forced into a smile and his mind breaking into pieces.
Animal Motif: The new Oyokal form he gains from the Core Medals created by Teruhiko include:
Nigh Invulnerable: In doll form. He took two bullets to the face, yet all that was shown were cracks. Hina punched him in the stomach, and all that's shown was porcelain falling out. It took a gun shot to the chest to take him down.
Ankh/Kamen Rider Helios
Reduced to a ghostly hand at the end of OOO, Ankh returns and warns Eiji of the impending doom that's coming to Japan. He somehow gained his own body, presumably from Teruhiko and the Cosmic Energy inside him. Unfortunately, he quickly became possessed by another serpent, Quetzalcoatl, that he is now contracted to. He has also been blessed with his own transformation belt to become Kamen Rider Helios.
Back from the Dead: Somewhat. His body is now made out of Cosmic Energy thanks to Teruhiko, but it'll fade away if nothing is done about it, hence the contract.
Blood Lust: Thanks to Quetzalcoatl. Quetzie explains that because his body is composed of Cosmic Energy—from Teruhiko's accidental collision—he needs blood in order to keep it stabilized, else the body will fade.
Would Hurt a Child: Doesn't think twice to slap Quetzie across the face for causing all of the above to happen. Jun stops him because while Ankh has a right to be mad, it's no excuse to beat up a little boy.
The eccentric head of the Kougami company, Kougami seems to know something about Ophiuchus and the War of the Stars. However, he'll only share that information for those who truly desire it. Also is good friends with Wadjet, a Serpent who is Damballa's missing wife.
Large Ham: It isn't Kougami without this. When Takashi Satake asks why he does it, Kougami replies that it shows of his desire to live.
Mister Exposition: Along with Satonaka, he gives a bit of an explanation to the origins of Ophiuchus and the term "Serpent-bearer".
Pals with Jesus: Is on good terms with Wadjet due to his desire to live fitting with Wadjet's ideals.
Kougami's secretary shows up with a cake and an invitation to the Kougami Company. When she's not eating cake, she's seen fighting any and all bad guys coming her way.
Combat Pragmatist: She fights dirty with hair-tugging and slamming people against the wall without mercy.
The former host for Ankh and his younger sister, both Izumi siblings arrive during Teruhiko's spare with Eiji and Ankh. Shingo weidls his gun while Hina prefers getting up close and personal to punch people into oblivion.
Backstory: Hina's super-human strength comes from a challenge her father made years ago: beat him in an arm-wrestling match, and she can go to fashion school. Hina then noted that she almost sent her dad in the hospital from the fight.
Charles Atlas Superpower: Hina, of course. She proves this by punching through a doll-transformed Eiji's stomach which was porcelain, and creates a large hole in his stomach. In contrast, Takashi left cracks on the face, and his knuckles were bleeding.
Girly Bruiser: Hina nearly sent her dad in a hospital in an arm-wrestling match, yet she's also trying to be a fashion designer.
A 23-year-old woman into cosplay who was recently fired from her job in a rental service. Jun invites her to the Cous Coussier to help prepare for a masquerade party with the chance of getting hired there.
Unexpected Character: She's not from a Kamen Rider Series, but rather an unofficial Super Sentai series.
Yaoi Fangirl: Squeals in delight of the video file Lovely gave her.
Who Decides/Wheel of Fortune Characters
Mei Shirakawa/ Madame Pollux
One of Ryusei's only friends, Mei is suffering under Yamada's reign as the Aries Zodiarts. She's usually shown with her tarot deck drawing predictions, mostly to figure out what happened in Who Decides as she was possessed when she gave Ryusei his fortune. Lives a very terrible life with Abusive Parents and jerkwad friends, and is willing to do anything to escape her fate.
Awful Truth: She has psychic powers but on the day she was supposed to prove them, she failed. If she did what she was told, her parents would've received the family fortune and the parents had to wait another six years for her to try again. What's worse is that her powers are at their best under stress.
Berserk Button: Anyone who says the words "Rental Service" will make her pissed. Learning things regarding her friends and family that affected her life makes her furious.
Iconic Item: Her tarot deck, given to her by her mother. It was given to her to gauge her powers, not out any love.
It's All About Me: She doesn't have a big of an ego, but it took her ten chapters in Wheel of Fortune for her to learn that Gentaro was resurrected. Renenutet explains it's because she's focused on her problems to figure out that there's more that meets the eye.
Meaningful Name: Pollux is a star in the constellation of Gemini, the Twins.
Never My Fault: Doesn't truly understand that she killed Haruto, but rather argues that she just summoned the swords that killed him and that it was Haruto's fault for not defending himself in time.
Psychic Powers: She supposedly has psychokinesis but only when under pressure.
Wild Card: By the time she's in Kyoto, as shown in both Horseshoes and SplitxEnd, she prevented Haruto and Yayoi from entering Kyoto—and even killing Haruto in the process—but gave Yayoi a reading in order to go save him.
Ros and Guil
The two boys that were seen with Mei in the original series are nothing more than hired hands from Yamada Tatsumori himself. They really don't care about Mei's plight and are just sticking around to get their well-deserved paycheck for having to deal with Mei's problems for three months.
Abusive Parents: Their mom was a drunkard who tried to seduce them after their father died.
Berserk Button: Ros doesn't like it when he has to be reminded of his mother. This even extends to Guil, his own brother, trying to explain it.
Everyone Calls Him Barkeep: Mei named them Ros and Guil from the Shakespeare play because she keeps forgetting their true names, but the forums she visited also call them that.
Fate Worse than Death: Renenutet devouring them means that they'll be erased out of existence—no one will remember them and it'll be like they were never born in the first place.
Freudian Excuse: They used to be sweet guys but when their dad died, their mom went on the deep end with alcohol and her constant attempts to seduce them due to their resemblance to their own dad. They got her out of their hands by putting her in the rental company for some "rockstar looking for a girlfriend", but they also were settled with debts and had to pay them off in the rental company.
Jerkass: Ros, especially. Guil's no better by just following along.
Only in It for the Money: They acted like Mei's friends for a paycheck. Of course there's a good reason why they need it, but they would've lived if they weren't complete jerks.
Satellite Character: Guil, seeing as he is there to make comments on his brother's angry tirades.
Unwitting Instigator of Doom: They asked the rental company to send their mom to a "rockstar looking for a girlfriend". Said rockstar was JK's father, and their mother would eventually kill his daughter, Keiko, and leave JK with a Survivor Guilt complex
Taeko and Shion Shirakawa
Mei's loving mother and father. They're too busy with their jobs to realize Mei's unhappiness (that and Yamada's presence) but they do notice that they have to be complete jerks to their daughter.
Asshole Victim: They were killed in a pretty gruesome way by Renenutet.
Bitch in Sheep's Clothing: Shows his nasty side at the end of Wheel-14 to Mei, stating that in the rental business you don't trust anyone. Then, he brings up his original cheery facade as if to rub it in her face.
Smug Snake: Rubs it in Mei's face on how she's too naive to believe he's a Nice Guy before going back to said nice guy persona.
Split x End Characters
Characters that debut in SplitxEnd .
Yayoi Tokuda/Split x End
Former Coma Zodiarts attending college. Her life consists of waking up, going to school, going home, etc. Upon hearing from JK on Gentaro's death, and seeing him attending his funeral, she becomes determined to unravel this mystery while also getting sucked into the mystery that is Gentaro Kisaragi.The title comes from her username in the forums.In Intermission-3, she gets into a fight against Mei Shirakawa which results in Haruto killed and resurrected by Damballa. She vows to head to Futo to save him. She shows up in Month of Sundays in Futo with four swords making good word on her promise.
Beware the Nice Ones: The Coma Zodiarts incident aside, she's mostly worried about JK's safety and believes she's not as strong as she seems to be. This definitely doesn't stop her in Sundays-9.5 from using her new swords to slice off a Doll!Haruto's limbs and leave him to burn alive because he's no longer the one she grew attached to.
Cain and Abel: The Abel to Mei's Cain, seeing as they are cousins. Whether Yayoi knows this or not is a different story.
Claustrophobia: Yayoi has this based on an event in elementary school where bullies trapped her in a dark warehouse and barricaded the door with their bodies. When trapped in Gentaro's closet, she focuses on the information she has in hand to ignore her fear of it.
First-Person Smartass: Only when it comes to making comments regarding stuff she learns about others, ranging from learning that the Cancer Zodiarts was Kijima, to questioning where Ryusei learned the one-inch punch.
Fist of Rage: Upon Haruto's confusion over love. It ends in pain.
Fortune Teller: Koyomi's outfit for her in Split-11. In contrast with Madame Pollux's grey In the Hood cloak, Yayoi's is more colorful and gypsy-like.
Survivor Guilt: Blamed herself for getting Haruto killed during their confrontation with Mei, believing that she was too weak to do anything.
Tarot Motifs: After the altercation in Intermission-3, she carries a Four of Swords card representing the inner conflict she faced when Haruto was killed with Damballa resurrecting him and the guilt she had in not being strong enough to save him.
The interesting part is that the man depicted in the Four of Swords is Haruto.
JK's former rock-star dad who is currently working as a fishermen. He's still estranged from his son due to something that Yayoi calls "that incident", but he tries his best to be there for when JK needs him.
Noodle Incident: "That incident", which is the source of all the drama in the Jingu residence. It's revealed that it's due to his daughter's death a few years ago which made him drop out of being a famous rockstar.
Kit and Maya (KRSwan)
The protagonists from Kamen Rider Dragon Knight, Yayoi interacts with them in order to find information regarding Ophiuchus and Gentaro.
Early-Bird Cameo: They're shown in Intermission-2 prior to their official debut.
The Ghost: Aside from Intermission-2, Maya usually talks through to Yayoi in the forums.
The "Ringed Wizard" of fame. He appears in Tears-9 in a cameo before debuting in Split-3. He saves Yayoi from a run-in in the "men in white coats" and helps her uncover the mysteries behind Gentaro Kisaragi's past, planning to head to Kyoto to spread the news. In the process, he gets killed and revived by Damballa into a doll before being taken to Futo. Fortunately, he has recovered, but now his soul has fused with the Phantom inside him.Has his own story in "Imagine Dragons", which takes the events of SplitxEnd, but in his perspective.
Berserk Button: Threatening harm to Yayoi has become one to him. When WizarDragon suggested making a Phantom out of her, Haruto immediately became angry.
Only a Flesh Wound: After becoming a doll and having some trouble standing up, Yayoi grabs his arm to keep him from falling...only to reveal that his arm is ripped apart and sand falls down. His response?
A spiritual being mentioned by Goro. He was the very same crow who told Apollo regarding the affair of Coronis, Apollo's wife, with the mortal Ischys. His white feathers became black from Apollo's anger and his failure to serve said god made him become reincarnated within Asclepius's bloodline.
The Atoner: He reincarnates several times for failing to obey Apollo.
Clever Crows/Creepy Crows: Depends on who's the current chosen one at the time. Most descendants who become the White Crow are benevolent. Gentaro Kisaragi, the current bearer, is not.
I See Dead People: Grants this power to all reincarnations as part of his mission to send the souls to the afterlife.
Psychopomp: To repent for his crimes, he helps guide lost souls into the afterlife.
Small Role, Big Impact: His decision to reincarnate through Asclepius's bloodline is an important factor in Gentaro's past.
Winged Humanoid: Appeared in this sort of form to Gentaro, if Gentaro's journal seems to indicate.
The operator of the DenLiner who informs the Kamen Rider Club of Gentaro's status as a living dead. He lets the Kamen Rider Club bunk in the DenLiner during the Kyoto Arc. Station Master has also appeared, but takes a non-action role rather than join the front lines like Owner.
Sweet Tooth: Seeing the cake Takatora bought from Charmant had her nearly drooling, stating that they make her father's parfaits seem like sheet cakes.
Yaoi Fangirl: She can make Yumeria run for her money. Also considered a Deconstruction as she seems to forcefully get the boys she watches to delve deep not only into her own fantasies, but also theirs.
The Serpents are a race of beings that came from outer space and once fought in a large battle known as the "War of the Stars". When in contact with a deceased person, the person makes a deal to be brought back to life and then to be left in the helpless control of the Serpent itself and becoming a "Serpent-bearer" in the process. Each serpent has their own agenda as to why they are here, but none of them tend to be of any "good".
Time Abyss: Many of them lived for around thousands of years.
The Big Bad of the story who revives Gentaro from death. A very cunning serpent who takes sheer delight in his Serpent-bearer's desires to kill and destroy, his main goal is to revive King Ouroboros, the Serpent of all creation.
Non-Indicative Name: His constellation means "Serpent-bearer" but the term is actually given to Gentaro. Month of Sundays states that Ophiuchus was the combined name of the serpent (Ophiuchus) and the human based on the constellation itself, Asclepius. The story in-universe is that when Asclepius died, Ophiuchus took over the human body.
Noodle Incident: Hates humanity due to an incident where they betrayed him thousands of years ago.
A Serpent god of Voudou, he appears in Intermission-2 and is currently under the contract of Shotaro Hidari. He is shown to have no loyalties to anyone but his own and is one of the most dangerous due to his chaotic mind.
Berserk Button: Seeing the Aries Zodiarts II, as this is Miura brainwashed to become Aries in Sundays-5, makes him full of hatred due to the fact that the Zodiarts caused the death of his son and daughter-in-law, thus making his grandson lose his parents and he also lost his own wife in the struggle. He also doesn't like being compared to the Zodiarts in general.
Body Horror: Anyone who gets transformed into a Creepy Doll. Haruto becomes a cloth doll filled with stuffing, Eiji was a porcelain doll, and Shotaro's a wooden mannequin.
Faux Affably Evil: He makes Kijima run for his money. He acts like a jovial old man with his laughter and everything but the fact that he transforms Shotaro into a doll that spits out nails as a way of saving him from death tells you that he is evil to the core. Not to mention that, he also did it to Haruto in Intermission-3 and to Eiji in Sundays-8.5.
For the Evulz: Everything he does is for his own entertainment, nothing more. Turns out that he has a specific reason for all of this.
Freudian Excuse: He lost his wife and grandson in the struggle of the War of the Stars and has been trying to find a way to bring them back to life—or at the most, make replicas of them. He transformed people into dolls as a way to test his magical powers, but the problem was that he didn't have a good concept of the human mind.
Heel-Face Turn: After reuniting with his grandson, along with Jun's talk with him, he's decided to aid the Cosmic Hunting Dogs and undo the damage he did to the Kamen Riders
Light is Good/Light Is Not Good: His serpentine form is a large white snake. While it's good where he comes from (as white is a color sacred to him), it represents death in Japan. As of Sundays-4.5, he sports a human form that is all white and he is still rotten to the core.
This even extends to being able to make his own Kamen Rider persona, Kamen Rider Pierrot, which is all white and is shown to be nothing more than sadistic. It might change now that he's working for the side of good.
Man in White: His human form... which looks just like Shotaro.
Meaningful Name: Damballa relates to the Vodou Sky God, who's associated with snakes. Also, Vodou is often spelled as Voodoo... Yes, thatVoodoo. That can explain the Creepy Doll aspect though.
Not So Different: Despite being an ancient serpent with a Mardi Gras theme, he is also in search of a loved one which is how Jun relates to him—she lost a father and little brother and is still reeling, but she manages to live her life to the fullest despite with it.
No Sense of Personal Space: Kissing his Serpent-bearer, or any person he resurrects, by the ear, wrapping around them and getting close to their space and sometimes nuzzling or stroking their face. Turns out that he has a reason for this: he needs physical contact to replicate the senses/qualities of things whenever he transforms one thing to another.
Pass the Popcorn: Eating popcorn from a "never-ending box" in Sundays-9.5 and even offers it to the audience.
Reality Warper: He transformed the Narumi Detective Agency into a large circus tent, not to mention transforming Haruto, Eiji and Shotaro into dolls.
Restored My Faith In Humanity: He wasn't keen on humans, but between Jun talking him down and reuniting him with his grandson, he decides to undo the damage he caused and ally himself against Ophiuchus.
A Serpent from the Aboriginal Myths contracted to Mari Yamamoto as of Intermission-1. She's shown as one of the least antagonistic Serpents so far and is rather neutral with the affairs of Ophiuchus and the heroes.
Composite Character: Her nickname is based on the Aboriginal Serpent, and when Mari uses her power she says "Iris", the Greek Goddess of Rainbows. The Rainbow Serpent's true name is based on a Voudo Rainbow Goddess who is married to Damballa and shares his veve.
Humans Are Interesting: She decides to aid the Cosmic Hunting Dogs because of this and of Mari's determination to save Shotaro.
Meaningful Name: Her real name is Ayida-Weddo, who is associated with serpents and Rainbows in Voudou and is Damballa's wife.
The Medic: What her power boils down to. It doesn't work on Serpent-bearers, though.
She states that she can't counteract Damballa's powers because he was the one who taught them to her. However it's shown that while she can't remove the brainwashing spell, she can at least heal wounds.
Red Is Heroic: Her body is mostly red, and she is shown working for the good guys.
A Serpent from Ancient Egypt contracted to Mei Shirakawa as of Wheel-6. Her motivations are unclear at this moment, but she might know more about the whole incident then what's being told. It is revealed in Tears to Shed that she is Ophiuchus's big sister. There are hints in Wheel of Fortune that she's looking for her beloved, Marcupo and that Virgo was the one who separated them.
Ambiguously Evil: She supports some of Mei's ideals, but she isn't one to note that most of Mei's problems are her own fault, not to mention that she knows that her younger brother has come back.
Fortune Teller: Her guise in Wheel-8. Curiously, her alias is "Madame Pollux", the fortuneteller Ryusei met up with in Who Decides?
Meaningful Name: Her name is from the Ancient Egyptian Goddess of nourishment and harvest. Interesting, one way of spelling her names in hieroglyphs is "fortune".
Ret Gone: What her power boils down to. She devours Ros and Guil and no one will ever know that they existed.
Tastes Like Friendship: Somewhat. In Tears-8 Ophiuchus states that if you give her an offering—like a donut—you'll be under her good graces.
Meaningful Name: He's named after a serpent from Norse Mythology. As a bonus, Jormungandr is depicted as biting his own tail which is also similar to his father, King Ouroboros, much like how JK has his estranged relation with his father.
Wild Card: He shows up and saves Amazon from Ecydsis and Apep. Then he destroys one of the last two pillars sealing the Cosmic Energy away, stating that it was better that the pillars were destroyed now rather than later when it absorbed more energy.
The Vessels are people who have been 'chosen' by Gentaro and given a name and powers based on said serpents.
Meaningful Rename: The vessels gain special names based on different serpents, barring Ecydsis and Neroda.
Apep ( Kengo Utahoshi)
Kengo, formerly a member of the Kamen Rider Club, was the first person inducted by Gentaro into becoming the first Vessel. His spell was momentarily broken by Ohsugi, but reinforced by Ecydsis. According to Ecydsis, Apep is his son and once ruled Ancient Egypt with an iron fist, until he was defeated by Ra, the Sun God.
Berserk Button: Hurting his father, Ecydsis or any reference to his other father Rokuro Utahoshi.
Meaningful Name: As mentioned in the description: Apep was defeated by the sun god Ra. Kengo also shared that trait with Apep in the TV show, being killed by someone who (in someone's eyes) represented the sun.
Jiro was the friend of Ryusei whose coma was the beginning of Ryusei's path to become Meteor, dying a few days after the events of Ryusei killing Gentaro and Gentaro's resurrection. Resurrected by Gentaro, he was brainwashed to believe that Ryusei hated his guts.
Meaningful Name: Serpent of Obsidian Knives is a minor giant and symbol of sacrifice in Aztec Mythology. Jiro's coma was the catalyst of Ryusei becoming Meteor and Gentaro said that he'd be the sacrifice to resurrect Jiro.
Psycho Lesbian: Acts like this toward Kengo, because Gentaro brainwashed him to act like this to ease his own boredom.
Small Role, Big Impact: His coma was what caused Ryusei to become Kamen Rider Meteor in the first place and why Ryusei killed Gentaro.
Walking Spoiler: Knowing his true identity helps you understand what Ryusei was trying to prevent.
Ecydsis (Kouhei Hayami)
Kouhei Hayami was once the Libra Zodiarts, but Gentaro changed that. His mind and body have now been taken over and his identity has been altered to reflect that change. His powers haven't been revealed, so he mostly fights as the Libra Zodiarts for the time being.
Your Soul Is Mine: It's revealed that Ecydsis took over by consuming all of the Cosmic Energy Hayami had with him, which was pretty easy considering Hayami was a Horoscopes general in the first place.
Nerodia (Yuri Kuramochi)
Once a Lunar Witch to Ritsuko, Yuri was brainwashed to become Nerodia and enacts revenge on Miu, who supposedly left her while she suffered at the hands of the swim team. She was freed by the combined attempts of Miu, Tomoko, Yuki and Erin.
Squishy Wizard: If he's without his pens, he's pretty much defenseless.
That Man Is Dead: "In a former life, I was Raito Sonozaki. In another, I was simply known as Philip. Now, I have been christened as Leviathan, and I shall be the one to dictate your death."
Kukulkan (Misa Torizaki)
The former priestess of the Cygnus Zodiarts, her life went downhill for that one action. She gets bullied around by Kengo, Jiro and Gentaro before being killed by her own hand then resurrected. JK's intel suggests that Misa had a pretty crappy life even before that incident with Cygnus.
Cerebus Retcon: Wanna know why Misa even made the Ugly Ducklings cult in the first place? See below.
Driven to Suicide: Implied by what Jiro went said, although it could be suggested that she was brainwashed/physically manipulated to do so.
Flechette Storm: Uses feathers as throwing daggers, similar to Cygnus Zodiarts.
Freudian Excuse: She was part of a rental company owned by Yamada's older sister, running away from her mother and abusive step-dad. On the night that Cygnus saved her, she was going to be raped by some guys. Seeing Cygnus gave Misa hope and she made the cult to express the feelings of goodness and to spread that type of goodwill toward others, and also severed ties with the rental agency. Unfortunately, the agency got wind and they put her through some demeaning jobs as punishment. This left Misa so bitter that by the time she was given Norio's switch, she took it just to gain some control in her life.
Meaningful Name: It's the name of a feathered serpent in Mayan mythology. While Misa wasn't Cygnus, she did lead the cult that worship Cygnus into invoking its Last One phase.
Never Live It Down: In-universe. Most of the school talk behind her back as to what she did regarding turning Norio into a Zodiarts and the cult in general. Gentaro notes that for the rest of her life in Amanogawa High, she's going to be called the "Swan Bitch" because of it.
Revenge Fic: Her part in the story pretty much states how much the author hates her.
A girl who is obsessed with being Gentaro's girlfriend to the point that she hates any other girl who was dating with him who ultimately dies by Gentaro's hand after ignoring everyone's advice on how evil he was.
Stalker with a Crush: An interesting variant; she kept chasing after Yuki due to her being friends with Gentaro.
Yandere: Upon hearing of Gentaro's date with Nadeshiko, she rips up her field program and threatens to kill her when they meet.
The main antagonists of the original Kamen Rider Fourze which have been sidelined as the threat of Ophiuchus has risen. While many of the original switchers are here, many of their personalities have changed for the worse.
The Zodiarts of the Ram and the harbinger of all that has happened thanks to the Deal with the Devil invoked with Ryusei. Yamada was sent into a coma after a resurrected Gentaro destroyed him and his Zodiarts Switch. Chapters later, Miura was brainwashed to become the second Aries, thus beginning the birth of the Cosmic Hunting Dogs and beginning the plot of A Month Of Sundays
Accomplice by Inaction: Yes, Ryusei was the one who screws everything by killing Gentaro, but he wouldn't have done so if Yamada didn't make the deal in the first place.
The Zodiarts of the Twins, Yuki chooses to become a Zodiarts so she doesn't give Misa and Yukina the satisfaction of seeing her in pain. Instead of both sides of Yuki fighting for control, the two are able to work together against their common enemy.
Actor Allusion: Dark Yuki wants to call herself "Fumika", which was the name of Yuki's actress.
Adaptational Heroism: Dark Yuki wanted nothing more than to let the original Yuki suffer. Here, she's willing to fight alongside the true Yuki.
The Zodiarts of the Crab, Kijima returns and is still as ruthless as ever. No longer using a switch, his left arm is now a large crab claw which he can use to extract souls. His body is also hard to hit and can withstand multiple blows without worry (unless you go for the head).
Adaptational Villainy: Brainwashed Ryusei and gave him Cosmic Energy injections, told him to sever the Kamen Rider Club (Ryusei took it as killing them), reconstructed Ryusei into a cyborg and brainwashed him again, and did experiments on Sonada and Kijima that lets them harness their original Zodiarts powers without switches. Not to mention that he forced Miura to become the second Aries Zodiarts. Plus he nearly got Ryusei to kill JK had Nadeshiko not show up just in time. He's clearly not the Big Good of the story anymore.
Mad Scientist: Started doing Cosmic Energy Injections to Sonada, Kijima,Ryusei, Erin and Yuki with all but Ryusei retaining their Zodiarts powers from it. Gamou then takes this idea, setting the plot for Month of Sundays.
Villainous Rescue: Saves Miu in Chapter 27 of Horseshoes after Gentaro flings her into the sky.
The Zodiarts of the Scales and Principal of Amanogawa High, Hayami was the first target by Gentaro for his nefarious deeds. Gentaro succeeded and Hayami has been taken over by a serpent going by the name of Ecydsis.
Berserk Button: Hayami hates it when he's referred to as a Master of None or if anyone makes remarks about him being weak. Of course, that was actually the point. Gentaro riled him enough to inject venom into his system and then erode his sanity.
That Man Is Dead: Hayami is no longer called by his true name, and the story calls him Ecydsis.
Scorpio Zodiarts (Sarina Sonada)
The Zodiarts of the Scorpion and the first Horoscope Zodiarts to debut in the original show. Sonada has a huge grudge against Mari for what happened when she tried to make Miura a Zodiartsnote Mari's album of Miura was what made Miura back down on the offer to get another Zodiarts Switch. She's gone bitter from the Cosmic Energy Injections and is ready to lash out at anyone.
Crippling Overspecialization: She uses her stinger-like ponytail against Ohsugi for the majority of the battle, but when Ohsugi sliced it off, she was powerless. Given that she also hadn't eaten for months due to being in stasis, this is justified.
Freudian Excuse: States that she was bullied when she was school. Doesn't make her any sympathetic though.
Would Hurt a Child: She doesn't give two shits that she's hurting students she's supposed to protect.
Sagittarius Zodiarts (Mitsuaki Gamou)
The Zodiarts of the Archer and Big Bad of the original series, Gamou has recently learned of Ophiuchus and has decided to take matters into his own hands to ensure that he gains the Zodiarts Switchs needed for the Day of Awakening.
Unstoppable Rage: Has gotten very pissed over the fact that Gentaro has decided to destroy Zodiarts Switches necessary for his goal.
Would Hit a Girl: Kicks Nadeshiko's ass and easily defeats Rumi and pins her to the ground.
Would Hurt a Child: He kickstarts the plot of Month of Sundays by kidnapping former Switchers and giving them Cosmic Energy injections.
Aquarius Zodiarts (Erin Suda)
The Zodiarts of the Water Bearer, Erin accidentally became Aquarius by Hayami who was being manipulated by Gentaro as shown in Tears-7. Unlike her original counterpart, Erin shows no loyalty to Gamou and sides with the Kamen Rider Club to end the madness.Prior to the story, Erin was actually a student in Reefside High. Summertime Sadness shows that she had a crush for one Dr. Tommy Oliver but couldn't bring herself to reveal her feelings for him.
The Medic: The water from the jugs on her shoulders heals wounds.
Mythology Gag: When alarmed by Principal Hayami, she repeats the "Warm me next time" line she gave to Gentaro.
The Sixth Ranger: She's more associated to the Kamen Rider Club than to the Zodiarts this time around. Humorously, she went to the school and was taught by the teacher who is known as THE most well-known sixth ranger in history.
Teacher/Student Romance: Had a crush on Dr. Oliver as shown in Summertime Sadness. Dr. Oliver, on the other hand, is more amazed at Erin being one of his best students.
