- Backstory: For many of the secondary characters.
- The Bus Came Back: For many of the Amanogawa students.
- Cast Herd
- 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.
- Attending Your Own Funeral: In Tears-5, he did. In SplitxEnd-1, Yayoi was the only one who noticed him.
- Axe Crazy: Gentaro doesn't care if he's going to shed blood, he will do so.
- Became Their Own Antithesis: The once happy and friend making Gentaro is now disgusted by friendship and is full of hatred.
- Berserk Button: Hates anything that has to do with friendship, Ryusei Sakuta or anything that makes him remember how he died.
- Big Eater: Even though he was resurrected, Gentaro needs to eat something once or day else his body starts to decompose.
- Black Eyes of Evil: To represent his change from hero to villain.
- Came Back Wrong: VERY much so.
- The Chosen One: SplitxEnd reveals that he's the legendary White Crow of the Veil, destined to send souls to the afterlife.
- Creepy Crows: He's really the White Crow of the Veil, emphasized by the white feathery wings and the symbol of a white yatagarasu Yayoi found in his bedroom closet.
- Damaged Soul: Thanks to Ophiuchus, he wants nothing more than to kill the Kamen Rider Club for leaving him to die.
- Eerie Pale-Skinned Brunette: Once in contract with Ophiuchus, his skin is colored white. His hair was originally white though, see below.
- 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.
- Evil Counterpart: Void States for Cosmic States.
- Face-Heel Turn: Not by his own choice though.
- Fallen Hero: Again, this is all Ophiuchus's doing.
- Glowing Eyes of Doom: They're usually black or white.
- 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 Control My Minions Through...: Uses Mind Control and Revenge for the male minions (particularly for Kengo and Jiro), for his female minons, he just uses Mind Control.
- 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. This is part and parcel with being the White Crow of the Veil, whose job is to help send souls to the afterlife.
- 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 current 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.
- Lineage Comes from the Father: The author's profile states that Aesclepius's descendants are from the male side of the family.
- Locked into Strangeness: In SplitXEnd 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.
- Manipulative Bastard
- 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, Gentaro is no exception.

- Significant Birthdate: In-universe. His birthday falls on November 30th. See below as to why.
- Stellar Theme Naming: Has access to many spells based on the constellations.
- 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.
- 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.
- Borrowed Catchphrase: It's assumed that his Catch Phrase: "Your fate is mine to decide" came from Madame Pollux's own declarations of her deciding his fate.
- Brainwashed and Crazy: Twice. Tachibana did this so Ryusei didn't protest to Cosmic Energy injections being pumped in his bloodstream, and the second was to make him believe he was always a cyborg.
- Broken Pedastal: To the entire Kamen Rider Club, Tomoko especially who was heartbroken over it all.
- Evil Counterpart: Meteor Impact to Meteor Storm.
- Evil Former Friend: Although 'friend' is being used loosely, considering what Ryusei was looking for.
- Evil Wears Black: His confrontation with Gentaro in the second day of Kyoto has him in a black gi, although we're not sure where his loyalties lie as of late.
- Fighting with Chucks: In Meteor Impact state.
- 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.

- Nice Job Breaking It, Hero: All of the stuff in the story wouldn't have happened if he didn't kill Gentaro, or at least realize that killing Gentaro wasn't the way to go.
- Red and Black and Evil All Over: Meteor Impact States.
- Red Eyes, Take Warning: The eyes on his helm when in Meteor Impact States.
- Sanity Slippage: The Cosmic Energy Injections made him mentally unstable that when Tachibana told him to "dismember the Kamen Rider Club" (as in: split them apart), Ryusei took it as kill them all!
- Shock and Awe:His Cosmic Energy Injections give him the ability to create red electric weapons.
- Slasher Smile: As he kills Shun back in XI-Team Spirit.
- Stepford Smiler: Type C, due to his brainwashing.
- 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.
- These Hands Have Killed: What he realizes when he sees a resurrected Gentaro at the beginning of Horseshoes.
- Unwitting Instigator of Doom: Everything in this series could have been avoided if he didn't kill Gentaro and just properly explained the whole situation to the Kamen Rider Club.
- Walking Spoiler: After the third chapter of Horseshoes, 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. He is given the ability to become Libra Zodiarts at the end of Horseshoes, which relates to his duplicitous nature.
Tropes associated with the Kamen Rider Club
- Badass Crew: Even without Gentaro, they're still capable of kicking ass.
- Beauty, Brains and Brawn:
- Break the Cutie: They were all affected by Gentaro's death, and the fact that they have to kill him again doesn't make them feel better.
- 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.
- Sensitive Guy and Manly Man: JK the sensitive one to Shun's manly one.
- Town Girls: Otaku Yuki, Club Chairman Miu (middle) and Perky Goth Tomoko
Yuki Jojima''"Gentaro was my best friend, but now...now you're a monster. And do you know what you have to do with monsters? You destroy them."Gentaro's former Childhood Friend who is now determined to stand tall to save her best friend...even if it means if she must kill him in the end.

- 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.

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.

- Big Guy Fatality Syndrome: He's the first one of the good guys to get killed off in the Kyoto Arc.
- 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.

Tomoko NozamaPerky 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 Chick
- Fainting: Humorously gets into this once she sees Riderman and Amazon on their motorcycles.

- Love Makes You Dumb: He realizes that his love for Sonada blinded him to what was really going on. Ditching this trope 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.

- Team Dad: Gentaro's death made him realize that he had to step up because that is what Gentaro would want.

- 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?
- Took a Level in Badass: The Butt Monkey of Amanogawa faculty becomes a fearless leader determined to beat the Zodiarts up.
- 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.
- Badass: They're Kamen Riders—of course they're badass!
- Freudian Trio: Ban is Id, Norio is Ego and Motoyama is Superego.
- 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.

- Berserk Button: Like in his home series, hurting kids in front of him will invoke his wrath.

- Purple Is Powerful: His Super Mode when he absorbs Cosmic Energy.
- 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 which is more akin to an adrenaline rush.
Yuki Joji/RidermanThe 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.
- One Steve Limit: Due to having the same name with Yuki Jojima (due to her Shout-Out Theme Naming) he is usually known as Joji.
- The Strategist: What he lacks in cybernetics and super abilities, he makes up with plans.

- Odd Couple: Boisterous Bruiser Imagin and the calm, once perfectionist, painter.
- Red Oni, Blue Oni: Motoyama is the Blue to Momotaros' Red.

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.

- Curb-Stomp Battle: Norio is 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.
- Fanboy: According to Word of God, Norio likes superhero comics. His favorite superhero is Captain Marvel.
- 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.
- Took a Level in Kindness: Sieg's not as aloof than he was in the original series. Given the Darker and Edgier atmosphere of the story, it's probably justified.
- Turn the Other Cheek: Yes, the Ugly Ducklings forced him to become Cygnus Zodiarts, but Norio's forgiven them...but they seem to be too embarrassed by their actions to accept his forgiveness.
- "World of Cardboard" Speech: Norio delivers one in XIII-Web of Sin powerful enough to give Gentaro a Villainous BSOD.
Haruka Utsugi/Kamen Rider Den-O: Super Climax FormReplacing 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.

- Katanas Are Just Better: Wields one during her battle with Leo Zodiarts.

- 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.
- Big Damn Heroes: Saves JK from being killed by Ryusei in XIII-Web of Sin.
- The Bus Came Back: She wanted to see Gentaro again, so she gathered Cosmic Energy before transforming into a SOLU form on the moon.

- Chain Pain: But mostly uses the weighted chain to grab onto people.

- Tomboy: In comparison to cheerleader Jun and camera holder Mari.
- Tomboy with a Girly Streak: Likes pressed flowers and her masquerade outfit is the girly Rena Ryuguu who adores cute things.
- 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. Rumi's not happy with it seeing as her dad bought it for her.
- 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.
- Amusingly, her costume is Bad Girl, who is well known for beating people up with nothing more than a baseball bat.
- 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.
- A constant Running Gag in Blue-Eyed Boy mentions that she beat up twenty Dopants with nothing more than a baseball bat. Jun really feels embarrassed every time it's brought up.
- Big Eater: Brought up by herself and by Word Ofgod. Deconstructed because of how it veers into Post-Stress Overeating as she eats so much for all of the meals her father and younger brother will never get to eat. Considering that she's around 18 at the time (they died when she turned 8), she's been like this for ten years.
- The Chick/The Heart: Is the emotional center of the group, comforting others with kind words.
- Did You Just Punch Out Cthulhu?: She punches Damballa in the face when he was in the form of Kamen Rider Pierrot.

- Grievous Harm with a Body: She utilizes Shotaro's mannequin arm to fight Kamen Rider Pierrot.

- Oral Fixation: Places lollipops in her mouth to help her concentration or when she's depressed.
- "The Reason You Suck" Speech: She gives it to Damballa. It's enough for him to go to a small Villainous BSOD.
- 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".
- The Snack Is More Interesting: While Kougami and Satonaka explain about Ophiuchus's origins, Jun is happily munching away on cake.
- 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.
- 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.
- Heroic Willpower: It saves him from Gamou's Mind Control.
- Make Me Wanna Shout: Has a supersonic howl that can knock-back enemies.
- Spike Shooter
- 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.
- You Have to Believe Me: When he tries to tell his fellow Switchers (Ritsuko, Jin, Makise, Nonomura, Tamae and Nitta) about what's happening regarding Gentaro. Needless to say, no one believes him.
- Action Dad
- Adult Fear: Suffers through this over his son being kidnapped in front of his eyes and his inability to do anything to save him. He calms down a bit once the two reunite in Sundays-8.5

- Papa Wolf: He nearly got in a fist fight with Terui when Terui didn't want to do anything with saving Teruhiko.

- Boom, Headshot: A victim of this by Akiko/Kamen Rider Skull.
- Came Back Wrong: Just like every other Serpent-bearer.
- Creepy Doll: Becomes one thanks to Damballa, but the story insists that he is a "Mannequin".
- Curb-Stomp Battle: His fight with Ophiuchus in Horseshoes Intermission 2 pretty much has him tossed aside like a ragdoll.

- Manchild: The fragmented personality Damballa gave him and the personality Shotaro takes up once Damballa brainwashes him.

- No Sell: When Shingo fires a bullet to his brain, it doesn't even phase him.
- Purple Eyes: Gains these under Damballa's control.
- Scary Teeth: They're nails.
- 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:
- Trauma Conga Line: Oh boy...

Kamen Rider OOODebuting 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
- 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:
- Creepy Doll: Gets transformed into one by Damballa.
- The Cameo: He's mentioned by Erin in her story of Summertime Sadness, where he helped Dr. Oliver with his paleontology work.
- Mind Rape: A victim of one by Damballa.
- 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
- 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.
- Demonic Possession: A serpent entered into his mouth, creating a Serpent-bearer contract.
- Eye Scream: Gets both of his eyes pierced by a huge nail, courtesy of Shotaro.
- Animal Eyes: Mari gives him a new pair, which look just like a serpent's.
- Sir Swears-a-Lot:
- 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.
- 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.
- Bodyguard Babes: Loyal secretary to Kougami and a powerful ass-kicker on the side.
- Combat Pragmatist: She fights dirty with hair-tugging and slamming people against the wall without mercy.
- Mister Exposition: Helps explain the origins of Ophiuchus along with Kougami.
- Mysterious Past: According to Word of God, she once was part of the Family Circle and stayed there for five years. She then left it because "she was bored".
- Shut Up, Hannibal!: Sonada tries to tell how the two are pretty similar to one another. Satonaka bashes her head against the DenLiner window repeatedly.
- The Stoic: Barely phased with anything that comes her way.
Shingo and Hina Izumi
- 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.
- Brother-Sister Team
- 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.
- Good Old Fisticuffs: Hina usually fights people with her own fists.
- Guys Smash, Girls Shoot: Gender-flipped. Hina's the one using her bare fists and super strength, while Shingo's using his gun at the adversaries.

- Seen It All: When Teruhiko starts explaining about what happened to him, neither sibling sound shocked about it.
- Wrestler in All of Us: Hina subdues Eiji with an elbow drop and an ankle lock.
- Cosplay Otaku Girl: She has to be considering her restaurant. Becomes quick friends with Yumeria because of that.
- Plucky Girl: It doesn't matter what's going on, she's going to do as much as she can to cheer everyone up.
Yumeria Moegi (real name: Yuko Yamada)
- Cosplay Otaku Girl: Of course—Jun suggested she'd come to the masquerade at the Cous Coussier because she'd have a giant supply of costumes.
- Dark and Troubled Past: There are hints that she has one, aside from her mother dying she was put in an orphanage. The rest isn't told as she's interrupted by Mari and Miura's waltz practice.
- Early-Bird Cameo: She actually appears in Wheel-14, getting her fortune read by Mei Shirakawa.
- Fangirl: Of a show called Gypsy Dragon, mistaking Yayoi as her cosplaying the main character.

- Happily Adopted: The author's notes say that she was adopted by a man named Ryoma Yamada when she was seven.
- Head Desk: Does this in frustration over losing her job and not being able to pay rent in Month of Sundays.
- In-Series Nickname: Judging by a text-message from Lovely, her nickname is "Yumeri".
- Intergenerational Friendship: Friends with Jun Shigeno, seeing as Jun has her cellphone number.
- Sempai/Kohai: Has this relationship with Luna Ishwamizu as shown in Cherry Picking and Confessions On a Dance Floor, where Luna calls her "Yuko-sempai".
- Shipper on Deck: Considers Haruto and Yayoi's relationship to be adorable.
- 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 from Forbidden Fruit.
Mei Shirakawa/Madame PolluxOne 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.
- Abusive Parents
- 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.
- Break the Cutie: Her life sucks.
- Cain and Abel: The Cain to Yayoi' Abel, seeing as they are actually cousins. Yayoi doesn't know this though.
- Demonic Possession: Was a victim of this in Who Decides, but doesn't know who or what did it. Signs all point to Renenutet on this one.
- Driven to Suicide: Commits seppuku so that she can make a contract with Renenutet.
- Fortune Teller: She's the one in Who Decides?
- 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.
- Locked Out of the Loop: Has been slow to realize that Gentaro was resurrected as she's too absorbed to figure out her own dilemmas.
- 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.
- Western Zodiac: Ryusei reveals she's an Aquarius in Why Decide?
- 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 GuilThe 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.
- Accomplice by Inaction: Guil, by virtue of just standing there while his brother rants.
- Ascended Extra: They were just to guys who were with Mei in the original show, but here they have more background.
- Asshole Victim
- 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.
- Prophetic Nicknames: Their nicknames are of two characters from Hamlet, a well known tragedy. It's a no-brainer what happened in the end.
- Satellite Character: Guil may come like this, seeing as he is there to make comments on his brother's angry tirades.
- Sir Swears-a-Lot: Ros does this when on an angry tirade.
- Shout-Out to Shakespeare: Their names are the shorten versions of Rosencrantz and Guildenstern, names of the (very) minor characters in Hamlet but the protagonists of Rosencrantz and Guildenstern Are Dead.
- Those Two Guys/Those Two Bad Guys
- 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 ShirakawaMei'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.
- Ain't Too Proud to Beg: When they are about to be devoured by Renenutet, they beg for mercy. Renenutet won't have that.
- Asshole Victims: They were killed in a pretty gruesome way by Renenutet.
- Greed: See below.
- Jerkass: They act mean because their daughter screwed them over in getting the family fortune and have been acting like jerks so she can manifest her powers and make them rich.
- Original Characters
Mitsuko, Yoko and MidnightThe usernames of three people on the forum that Mei frequents. They discuss a bit of the backstory regarding Yamada, Ros and Guil, and anything regarding the rental service that they worked in. So far, the only one revealed is Midnight, who is Luna Iwashimizu.
- Foreshadowing: Yoko mentions about Gentaro dying and how she had so much planned for him. This is probably Yukina Takamura who went crazy during the trip due to Gentaro's death.

- Greek Chorus
- Mr. Exposition: Their chats reveal a lot of backstory regarding Ros, Guil and Yamada Tatsumori.

Ryu, Donut Hungry Shop EmployeeA teen who works at the Donut Hungry Shop whom Mei befriends. He's really an observer sent by the rental company to keep an eye on Mei.
- Ascended Extra: In the original show, he was only there to be comic relief with the Hungry Shop Manager and was basically a Flat Character in general.
- 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.

- Berserker Tears: Sheds these during her Kill It with Fire moment with Haruto.
- 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.

- It actually worked. Haruto revealed chapters later that he heard it, but decides that they should take it steady.
- Non-Action Guy: Deconstructed. She hates being this, and can't join JK and the Kamen Rider Club because she feels as if she's going to weigh them down.

- 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.
- Trademark Favorite Food: Croquettes, particularly cream crab ones. It serves to be an interesting opposite to Haruto's love of sugar donuts. The author states that she and JK first met when JK accidentally made her drop a bag of croquettes she was going to share with her parents.
Keizou JinguJK'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.
- Cool Old Guy: Presumably from being a rock-star.

OphiuchusThe 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.
- Dark Is Evil: He's usually seen as a black serpent.
- Manipulative Bastard
- 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.
- Red Eyes, Take Warning

- Evil Laugh
- 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.

- Man in White: His human form...which looks just like Shotaro.

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.
- Butt Monkey
- Cerebus Retcon: Wanna know why Misa even made the Ugly Ducklings cult in the first place? See below.
- Complaining About Rescues They Don't Like: Misa's reaction to finding out that Wing Den-O was Norio was to reject his offer. The author's profile states that it's because she hates Norio for not being able to give her the freedom she wants.
- 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.

- The Bus Came Back: Last mentioned being stuck in the M-BUS satellite, but returned thanks to Ohsugi teleporting him and Sonada out of the satellite.

- 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.
