This is a partial character sheet for Kamen Rider Revice. Subjective trope and audience reactions should go on the YMMV page.

Emblem of Fenix

A government special-ops agency formed to oppose the Deadmans. They seek the eradication of all demons and the eventual end of the Deadmans with them.

In General

• Cool Airship: Their base of operations, Skybase, is a giant Flying Aircraft Carrier that goes around the city. It gets wrecked by Giff at the end of #35.
• Face–Heel Turn: Following their defeat against Giff, Fenix becomes the arm through which Giff's obediance stamps are distributed to the populace.
• Failure Hero: Fenix was never intended to actually defeat the Deadmans or stop Giff's revival, as their leader is in cahoots with Giff. Once Giff is revived, Akaishi stages their defeat against Giff to persuade the public its hopeless to fight against the demon.
• Gender Is No Object: Fenix doesn't seem to have restrictions in regards to gender for when it comes to who can join, as seen by the female soldiers among their ranks.
• Heel–Face Turn: By the end of the series, what's left of them and Weekend are basically merged into Blue Bird.
• Hourglass Plot: Spend the first half of the series as the good guy organization supporting the Riders in their fight against the Deadmans. Once Giff is revived as per their leader's plan, they become the antagonist faction of the second half.
• Light Is Good: Their members wear white military uniforms. Though for some of their members, it's the opposite.
• Meaningful Name: The organization's name is the Spanish word for The Phoenix, and it works in both ways:
  • The fact that they share the same Hispanic naming sense with the Deadmans cult foreshadows a link with the Deadmans. It turns out later that at least one member of the cult has infiltrated Fenix in a high ranking position, and then there's the big reveal that the Fenix director is the founder of the Deadmans...
  • Additionally, phoenixes have been known to revive upon dying. After the events, Daiji rebrands the organization as the Blue Bird Organization.
• Men of Sherwood: The soldiers of Fenix are skilled enough to at least be able to take on the Deadmans Mooks. Compare this with Ikki, who handily lost to the same Mooks when he wasn't transformed.
• Mirroring Factions: As the series goes on, Fenix starts to share more and more similarities with the Deadmans they are fighting. Both seek to harness Giff's power for their own ends, both use individual members as pawns and both are led by the same guy.
• Mook Carryover: After they begin their "strategic regression" plan, they start using both Giff Juniors and Gifftarians as footsoldiers. Makes sense, as both they and the Deadmans are run by the same person.
• Rank Up: The military of Fenix has a ranking system that seems to go Soldier > Squad Leader > Deputy Commander > Commander. There are occasional promotions.
• Red Armband of Leadership: Fenix Squad Leaders all wear red armbands.
• You Have Outlived Your Usefulness: Akaishi has Giff destroy the entire organization once his plans for it have wrapped up.

Leadership

Hideo Akaishi (Unmarked Spoilers)

Hideo Akaishi/Giffdemos (White)/Gigademos

Portrayed by: Jun Hashimoto (live), Satoshi Fujita (suit)

Great Leader of Fenix and Deadmans

Akaishi's Giffdemos form

Gigademos

Fortune is a fickle friend, as they say.

The director-general of Fenix. He is later revealed to also be the founder and leader of the Deadmans cult.

---

• The Ageless: He looks the same as he did 30 years ago, on account of the immortality Giff gave him.
• Ambiguously Evil: He doesn't do anything evil at first, but his shifty demeanor, similar design to Apollo Geist's human form, and the way he observes Giff's casket imply he doesn't have wholly good intentions in mind. Nor do his ties to George. #20 also features a hooded Deadmans worshipper with a chin and posture that looks suspiciously like his. The "Ambiguously" part is dropped once he releases Orteca.
• Ambiguously Human: Masumi points out in #30 that he hasn't aged a day since the 90s, and theorizes that he may be one of Giff's children just like the Igarashi siblings. This is further evidenced by the fact he seems to understand Giff's growls and by the fact that his hand contains a part of Giff. We eventually learn he's an ancient being whom Giff gave immortality, although he doesn't specify if he was an ancient human being.
• Ancient Conspiracy: He's been observing humanity for Giff for nearly as long as humans have existed.
• Ancient Evil: He claims to be from ancient times, and to have made a deal with Giff that gave him immortality.
• Arc Villain: He becomes the main antagonist following Orteca's demise, but is killed in #43 right as Giff himself sets foot on Earth.
• Back for the Dead: He is initially killed by Ultimate Revi and Vice in #42, but is resurrected by Giff in the following episode to continue carrying on his will. A shot in the chest by Daiji gives him a more permanent death.
• Bad "Bad Acting": He overacts quite a bit when faking being attacked by Giffdemos in the middle of his announcement in #35, clearly trying too hard to make his audience succumb to despair.
• The Bad Guy Wins: From the moment Akaishi plays his hand, the series becomes one long string of victories for him and defeats and failures for his enemies. He succeeds in reviving Giff in #28, and follows up by broadcasting the Riders' defeat and FENIX's destruction at the hands of Giff in #35, scaring most of humanity into submission and letting him move forward with the next phase of his plan. From there he's able to frame Ikki for killing Akemi in #37, which lets him isolate Daiji from his siblings and groom him to be his new apprentice by #39.
• Badass in a Nice Suit: He beats up Daiji, all while in the white tuxedo he wears as director of Fenix.
• Big Bad: Although he serves Giff, Akaishi is the mastermind behind just about everything bad that happens, having founded the Deadmans and commandeered Fenix to achieve his vision of humanity's subservience to a world order led by demons.
• Big Good: He's essentially Wakabayashi's boss, and from #16 starts overseeing operations directly. However, he is also shown to be in cahoots with George for ambiguous reasons, with some implications that it's related to Giff, and then #21 reveals that he's actually the founder of Deadmans, making him the...
• Body Horror: Has a fragment that resembles Giff's casket embedded in his right palm.
• Boomerang Bigot: While he is implied to be still somewhat human, he believes that humans are the real demons, due to being heavily advanced and labeling Giff as a devil even though he was supposedly helping them.
  Akaishi: Because humanity has progressed too far. Their sciences and weaponry are now capable of posing a threat, even to the cosmos above! Humanity themselves are the true demons.
• Character Tics: He tends to stand with his hands open in front of him, with both palms facing himself. #20 shows that the Deadmans' founder shares this trait, a clue that they are the same person.
• The Chessmaster: Manipulates Fenix, the Kamen Riders and the Deadmans in order to usher in Giff's awakening. By #28, he succeeds.
• Chessmaster Sidekick: To Giff. As Akaishi is the one familiar with human society, Giff leaves it to Akaishi to plan out their next move.
• Clasp Your Hands If You Deceive: Keeps his hands crossed at nearly all times, and is easily one of the most cunning and deceptive characters in the show.
• Combo Platter Powers: He can No-Sell gunshots, move around at Super-Speed, deliver painful attacks that burn through clothing, and turn parts of his body into a Nigh-Invulnerable material, as shown in #33.
• Conspicuous Gloves: Wears a pair of black gloves at seemingly all times. It's especially noticeable whenever he flexes his hands while staring at Giff's casket and making ominous remarks. Ironically, in the flashback of him as the Deadmans founder, his hands are the only thing that's not covered. Eventually we learn the reason why he wears gloves: he has a portion of Giff embedded in his right palm.
• Contrasting Sequel Antagonist: Both Isaac Kanda/Master Logos and Akaishi are the leaders of heroic organizations who are secretly in cahoots with the antagonistic factions. While Isaac betrayed his order out of boredom and disdain towards humanity, Akaishi seeks to uplift humanity and believes that subservience to Giff is the only way mankind can survive and transcend its "foolishness". Isaac saw himself as superior to everyone, including his partner Storious, while Akaishi reveres Giff.
• The Corrupter: Seeks to turn Daiji Igarashi into his new apprentice, viewing him an ideal candidate to lead humanity in the new era he intends to usher them into, on account of him being part Giff. He does this by killing Akemi and making it seem like Ikki was responsible, letting him isolate Daiji from the rest of his family and fully turn him by convincing him that opposition to Giff will only result in needless human casualties.
• Create Your Own Hero: As head of Fenix, he sanctioned the creation of both the Revice and Two Si Drivers, and their use by Ikki and Daiji to fight the Deadmans. Furthermore, he was also a board member of NOAH, the organization which experimented on Genta Igarashi with Giff's cells and led to his children inheriting them, which is what enabled the three Igarashi siblings to even become Riders in the first place.
• Deal with the Devil: Made a bargain with Giff in ancient times, granting him great powers in exchange for steering humanity's development to Giff's will. Given the powers he got out of the deal, he's essentually a warlock: immortal with enhanced physical and magical abilities even untransformed.
• Diabolical Mastermind: Akaishi is a shadowy but very influential figure, manipulating organizations like NOAH and Fenix to use their research for his own ends, all while establishing and running the Deadmans cult to lay the groundwork for Giff's return.
• Dragon-in-Chief: For the first half of the series, since Giff is sealed, it's Akaishi who's actually running things and giving orders to the other villains, either directly or from behind the scenes. Although he steps out of this role after Giff returns, Akaishi is still at the helm of everything the bad guys do.
• Engineered Heroics: Given his heavy interactions with Giff post-resurrection it's highly implied he orchestrates attacks using Gifftarians (TRUE) both to continue heading Fenix's attacks against them and to keep his subordinates distracted from pursuing any leads of a connection between him and Giff.
• Evil Genius: He's the main planner on Giff's side and the one who handles the logistics and preparation for Giff's advent into the human world.
• Evil Is Hammy: While he acts composed whenever he's acting as director of Fenix, he gets a lot more hammy and expressive when he's showing his true colors.
• Evil Running Good: Is a part of the same evil forces his organization is publicly committed to fighting.
• Evilutionary Biologist: Actually an inversion. He believes the best way to ensure humankind's continued existence is to halt their evolution and make them permanently subservient to Giff.
• Evil Wears Black: Downplayed. While he mostly wears white similar to the other Fenix members, he also wears black gloves instead of the white ones other Fenix members wear.
• Face Death with Dignity: After being shot by Daiji, Akaishi simply calmly smiles and bids him farewell before passing on.
• Failure Gambit: Akaishi's whole plan involving Fenix was for them to be destroyed by Giff upon the demon's awakening, in order to push humanity past the Despair Event Horizon so they'll willingly submit to him.
• Faux Affably Evil: He seems a lot more chummy as a villain than when he's acting as director of Fenix, but as time goes by, he shows his true malicious colors to the heroes while keeping up the facade of being the good leader to the general public. He acts friendly to Daiji even as he's smacking him down in #33 and allows him to stay alive so he could corrupt him to his side. He also waits for Akemi to willingly submit herself to Giff before turning her into Giffdemos before he finished her off once she lived up her usefulness towards him.
• Foreshadowing: There are a few clues that lead up to the reveal of him as the founder of the Deadmans:
  • His clothing design being meant to be reminiscent of Apollo Geist fits in with the Deadmans' homage to various Kamen Rider villains throughout the franchise.
  • The hooded figure in #20 has a chin resembling him and has the same Character Tics as him.
• Freeze-Frame Bonus: The file Masumi gives Sakura and Hikaru states he was born on August 26, 1964, is 168 cm tall, and his blood type is B.
• Gone Horribly Right: He planned to groom Daiji Igarashi into his apprentice after Orteca is killed. While he did so, Daiji's increasing doubts leads him to ultimately betray him and succeed Akaishi as Giff's servant.
• Good Is Not Nice: As the Fenix director he's very stern and no-nonsense. He's ironically a lot more chummy when he shows his true colors as a villain.
• Healing Factor: Easily shrugs off several gunshot wounds, courtesy of the Giff Stone in his palm.
• Hidden Agenda Villain: Given how he's both the head of Fenix and the founder of the Deadmans, he gives different answers on what his goals are depending on which side of the aisle he's talking to. Even when speaking to Giff, he claims to simultaneously want to evolve and regress humanity within the same sentence.
• Hoist by His Own Petard: In attempting to corrupt Daiji to his side, Akaishi only ends up creating his own replacement as Giff's herald, and Daiji rewards him with a bullet through the chest for his service.
• Homage: Dresses like Apollo Geist's human form. In his Giffdemos form, the horns on his head resemble the wings on Apollo Geist's helmet, particularly after he Turns Red.
• Hope Crusher: Orchestrates Fenix's downfall against Giff in order to make opposing him seem futile.
• Humanoid Abomination: He looks human, but he's immortal and has unnatural, demonic powers, courtesy of Giff. #34 confirms him to have once been a human king during the dawn of humanity before making a contract with Giff.
• Humans Are Flawed: Has this stance, as in his whole lifetime working with Giff, he's seen humans making the same mistakes over and over again.
• Hypocrite: Though he claims he wants to save humanity from being judged and destroyed by Giff, he ultimately values Giff's personal approval far more than this stated goal. When Giff commands him to attack ARARAT as part of putting himself back into Giff's good graces, Akaishi willingly does so with only the barest of hesitation, injuring and potentially killing many people in the process.
• If I Can't Have You…: Familial example; when Daiji refuses to see him as a father-figure, he decides to kill off the entire Igarashi family in retaliation.
• Irony: Despite his claims of being above humanity, Akaishi cowers like a human when Revi and Vice are about to finish him off; this also happens to save his life.
• Knight of Cerebus: Once his true identity and his powers are revealed, his appearance makes the tone of the story darker.
• Knight Templar: Is motivated by a desire to ensure humanity's survival, even if it means making them subservient to a demon-controlled new world order and sacrificing individual humans along the way.
• Large Ham: When he's on top, he's quite calm and composed, but whenever Akaishi undergoes a Villainous Breakdown, he descends into rarely-seen levels of cowardice and crying.
• Last Words: To Daiji, after the latter fatally shoots him:
  "Not bad at all... holy champion. Until we meet again..."
• Like a Son to Me: Views Daiji as this, which is made more evident when he personally tells Ikki to leave his family alone.
• Manipulative Bastard: Goads Daiji to his side by making it look like Akemi was killed by Ikki, and to further convince him that opposing Giff is hopeless and will result in more human casualties.
• Meaningful Name:
  • The two characters that make up his first name can alternatively be read as "Eiyū", meaning "hero" or "great man", which he certainly fits as the head of the main good guy organization. Though this becomes quite the Ironic Name given his ties to the Deadmans.
  • His surname contains the character for "red". Guess what color Apollo Geist's helmet and his Gigademos form is.
• Mortality Phobia: Given his immortality and ability to regenerate from or prevent almost any kind of damage, he hasn't really had to consider the possibility of dying. At the end of #41, after seeing his arm start to disintegrate and realizing that Ultimate Revice's attacks can actually kill him, he becomes so terrified that he miraculously dodges a fatal blow by cowering in fear.
• Mr. Exposition: He recaps the series to Giff in #29 after the demon's reawakening.
• No-Sell: The few punches Daiji lands on Akaishi in #33 do far more to hurt Daiji than they do Akaishi.
• Obviously Evil: Even before he actually does anything villainous, it's easy to guess he's up to no good from how shifty and sinister his demeanor is.
• Not-So-Well-Intentioned Extremist: #41 hints that his submission to Giff was a well-intentioned one so he could prevent what befell his kingdom from happening to humanity. However, his act throughout the course of the series proves that he's a hypocrite to his words.
• Older Than They Look: Downplayed; while he looks to at least be in his forties, and is shown to be 57 years old as of #30 (born in 1964), a picture shows that he looked exactly the same in the 90s as he does in the present day.
• One-Man Army: In his debut with his Giffdemos form, he mops the floor with Kamen Riders Jeanne, Aguilera and Over Demons. Ultimate Revice, not so much.
• One-Winged Angel: In #40 he has Giff transform him into a Giffdemos for battle against the Kamen Riders. He gets further upgraded in #43 into Gigademos.
• Orcus on His Throne: A justified example. He's one of the strongest characters in the series, able to blow back the Kamen Riders while untransformed, but doesn't fight himself because that would blow his cover.
• Out Gambit: In #37 the heroes try to capture Akemi to extract Giff's DNA from her. Not only does Akaishi make sure things do not go as planned, he turns the situation to his advantage by using it to drive a wedge between Ikki and Daiji.
• Palette Swap: Gigademos is a red version of his Giffdemos form.
• Pet the Dog: He spares Daiji and his siblings following their failed attack on him, believing since they all share Giff's DNA that they're family and shouldn't fight. Then he orders their deaths anyway.
• Really 700 Years Old: Due to his immortality, Akaishi has lived through many ages that shaped human history, and is implied to be millions of years old.
• Rule of Two: The moment he loses Orteca, he starts eyeing Daiji Igarashi as a replacement.
• Running Both Sides: He's both the founder of Deadmans and the director-general of Fenix.
• Spikes of Villainy: The shoulders and chest of his demon form are covered in spikes.
• The Man Behind the Man: He founded the Deadmans and recruited Orteca into their fold.
  • Prior to founding the Deadmans, Akaishi was a board member of NOAH, suggesting he had a hand in their activities as well.
• Transhuman Treachery: Became Giff's servant and received immortality in exchange. He takes it a step further by transforming himself into a demon in #40.
• Villain in a White Suit: Wears a white suit similar to the other members of Fenix, but is a villain instead.
• Villainous Breakdown: Goes through a major one in #41, courtesy of Giffard Rex: he gradually loses control of his usually-unflappable persona, which is then followed by an unhinged Motive Rant to Revi. After being trounced by Ultimate Revi and Vice, he is reduced to a whimpering, cowering wreck before simply stumbling away in a daze. He gets increasingly more frantic as his immortality starts to wear down and humanity continues to defy Giff, only regaining his composure after being fatally wounded.
• Villain Respect: In #40, he praises Hikaru for standing his ground, and even gives Tasuke a dignified sendoff.
• Walking Spoiler: It's hard to bring up anything regarding him without also bringing up how he founded the Deadmans and has worked closely with Orteca. His powers and relation to Giff is even more this.
• Warrior Poet: Akaishi is very well-read for a Diabolical Mastermind and takes it more literally by reciting the Furinkazan in combat on two instances — first when he corners Daiji, and the second one a paraphrased variant when he mops down the floor with the Weekend Riders as a Giffdemos.
• We Can Rule Together: He seems quite interested in positioning Daiji to be humanity's new ruler under Giff, viewing him as an ideal successor to Orteca.
• We Have Reserves: Declares to Daiji that he has faith in him and has great expectations as Fenix's new head commander, while simultaneously stating that Hiromi is expendable. He later allows Kagero to fight Daiji in a Duel to the Death, not caring if Daiji dies since he can simply contract Kagero in his place instead.
• Wicked Cultured: He has a poetic, eloquent way of speaking and often quotes proverbs when addressing events, suggesting he's quite a well-read man. He also quotes The Art of War (Sun Tzu) as he demonstrates his abilities while fighting Daiji in #33.
  Akaishi: "Be swift as the winds, silent as the forests, daring as a raging fire, and immovable like a mountain."
• Xanatos Gambit:
  • His overall plan is this. Even if the Deadmans fail to revive Giff on their own, if the Riders slay enough demons, Giff will absorb their energy and revive anyway.
  • In #26 he has George give Kagero the Crow Vistamp for him and Daiji to duel over. Either Daiji wins and becomes stronger, or Kagero wins and he contracts him in Daiji's place.

Yujiro Wakabayashi (Major Spoilers)

Portrayed by: Kazuya Tanabe

"Combat the demons with demons", huh...?

The head commander of Fenix, and the one who spearheaded the Revice System project for the purpose of exterminating the Deadmans.

---

• Authority Sounds Deep: Not so noticeable most of the time due to the light conversational tone, but his voice drops significantly lower after losing patience with George's temper tantrum due to Vice insulting the design of the Jackal Genome suits.
• Big Good: The only eminent executive of Fenix seen until #16, and is the one heading up the effort to fight the Deadmans. This becomes somewhat muddled when he tacitly agrees to let Kagero roam free with the Two SiDriver, despite being fully aware that he's possessing Daiji. And then comes the shocking reveal that he isn't really Wakabayashi at all.
• The Comically Serious: Yujiro always remains calm and stoic whenever he's dealing with George's antics. Even his patience is not infinite, though, as shown by his reaction to George's temper tantrum concerning the Jackal Vistamp.
• Dead All Along: The real Wakabayashi was killed by the Chameleon Deadman almost immediately after Ikki and Vice's first transformation in #1, who then went on to impersonate him up until the end of #14.
• A Father to His Men: The real Wakabayashi was shown to be this in a flashback in #19, encouraging Hiromi to not give up his dream of becoming a hero when the latter was thinking of quitting due to being the weakest of his cohort. He apparently provided so much inspiration to Hiromi that he became a Helpful Hallucination to him after the latter found out about his death.
• Helpful Hallucination: He appears as this to Hiromi in #21 and Page 1 of DEAR GAGA, giving him advice on what he should do as a hero.
• Impersonation-Exclusive Character: What we know of the real Wakabayashi outside of flashbacks and his brief scene in #1 is only via the Chameleon Deadman pretending to be him.
• Lantern Jaw of Justice: He's heading up the effort against the Deadmans and has one particularly strong jaw to prove it.
• No Body Left Behind: He is Reduced to Dust by the Chameleon Deadman.
• Reasonable Authority Figure:
  • While he's blunt in telling Hiromi he's demoted, he isn't wrong in criticizing him for using the Revice Driver when he was told not to.
  • When Daiji hastily attempts to take a new Driver that George was working on while Sakura was in danger, he only reminds Daiji that he needs to prioritize Fenix's duty to protect innocent people over any potential personal issues.
  • He tolerates George's For Science! shenanigans, but seems to consider all of that a necessary evil.
• Sacrificial Lion: His death reminds you that this series, while light-hearted, is still a Kamen Rider series.
• The Stoic: Rarely flinches and maintains a cool tone at all times. He couldn't deal with George any otherwise.
• Unwitting Instigator of Doom: His death at the hands of the Chameleon Deadman would indirectly cause the events of Final Stage, as his twin brother Yuichiro would be filled with regret over not saving his brother and later lead the families of Fenix soldiers lost in the Deadmans cult battles into a path of revenge against Fenix and later obtain the Crimson Vail Vistamp from a black market to become Blood Vade.
• Walking Spoiler: The reveal in #14 that he was Dead All Along and impersonated by a Deadman has a significant effect on the plot.
• We Hardly Knew Ye: The real Wakabayashi was Killed Offscreen mere seconds after his first appearance during the very first episode. His murderer then took his place right under Fenix's noses.

Hiromi Kadota/Kamen Rider Demons

Hiromi Kadota/Kamen Rider Demons (I)

Portrayed by: Junya Komatsu (live), Takuma Komori (suit)
Young Hiromi Portrayed by: Zenta Umegaki (DEAR GAGA)

I will never surrender. I would rather struggle; that's how my life goes!

A deputy commander-turned-squad leader of Fenix. While he possesses a genuinely strong sense of justice, it is often hampered by his own impulsiveness. Despite this, he quickly takes his new position in stride, fighting the best that he can to atone for his previous mistakes. After the raid on the Deadmans' base, he succeeds Wakabayashi as head commander.

Using the Demons Driver and the Spider Vistamp, he transforms into Kamen Rider Demons Spider Genome.

Tropes that apply to him in general

• Accent Relapse: In The Teaser for #13, while soaking in Happy Spa, being bummed on being put on the sidelines for transforming into his Rider self due to orders pertaining to his health, he wonders aloud if he should visit his mother, using the Miyagi prefecture slang "gaga".
• Achilles in His Tent: After learning that George was using him as a lab rat all along with no regard for his safety, he quit FENIX and nearly punched George on his way out. He then got blasted off a cliff by Orteca but survived, and decided to fake amnesia to avoid having to go back until Wakabayashi's Helpful Hallucination convinced him to return in #37.
• Affectionate Nickname: He's known as "Hiromicchi" to Vice.
• All of the Other Reindeer: In #12, he reveals to Daiji that he used to be bullied as a kid. It motivated him to become the sort of person he needed back then.
• The Atoner: He decides to transform into Kamen Rider Demons to redeem himself for his role in Daiji's supposed insanity.
• Badass Cape: Sports a dapper white poncho as deputy commander. Upon his promotion to head commander, he replaces it with a white trenchcoat.
• Badass Normal: You do have to commend him for at least trying to take on the Daiouika Deadman untransformed in #19, especially considering his body functions had already deteriorated to an 80-year-old's level of strength by that point.
• Baritone of Strength: While not quite as intense as Wakabayashi, he's a capable soldier on the battlefield with a rather gruff voice. While his return to the series after #37 see him take on a softer tone of voice, he is no less badass for it.
• Breakout Character: Hiromi's popularity among fans has led him to get his spin-off miniseries, DEAR GAGA, set after his supposed death, and would later go on to co-star with Daiji in the V-Cinema.
• Broken Pedestal: Due to his experiences in Fenix (tricked into using a Driver that drains his life every usage, death of his mentor Wakabayashi, his discovery of Akaishi's true personality and his near death experience in Orteca's hands) and his worry that he might left his mother alone if he dies for real, it drove Hiromi to claim that he has amnesia so he will never go back to Fenix.
• Big Brother Mentor: He acts as this to Daiji ever since he joined Fenix and even encouraging and giving him pep talk whenever he's feeling down.
• Character Development: He goes from an impulsive, hot-blooded soldier who easily gets manipulated to a calmer, wiser individual after going through his Disney Death in #21, brief retirement and subsequent return in #37.
• Dented Iron: Downplayed since he looks fine at first glance, but his constant use of the Demons Driver has severely worn down his body and internal organs, even before he appears to die in #21. He has a much harder time rolling with hits when he returns after #37, most notably demonstrated after he's forced out of transformation in #44 and has to shakily crawl his way to Daiji afterward.
• Determinator: As his quote suggests, Hiromi is made of this. Instilled in him by Wakabayashi during his training days, he will force himself through any situation in order to reach his goals. Hits its most extreme example when he finds out the Demons Driver is killing him. Now he's achieved his dream of being a hero, he will see it through even if he dies. His catchphrase is very much not just for show.
• Deus Exit Machina: Hiromi faking his amnesia and staying out of the conflict was an easy way to ensure that Akaishi doesn't get exposed for working with the Deadmans until it's far too late for any of the other Riders to do anything about it, especially as Hiromi returns a few episodes after the cat's out of the bag and Akaishi's plans are well into motion.
• Didn't Think This Through: In #1, he still attempted to use the Revice Driver despite George's warnings of his inability to control his inner demon, heavily believing Someone Has to Do It. He only ended up producing a berserk Rex Deadman from himself that attacked him instead.
• Disappeared Dad: There has so far been no mention whatsoever of his father. DEAR GAGA reveals that his father passed away quite some time ago.
• Disney Death: Gets blasted off a cliff by Orteca. He survives, albeit weakened from all of the fighting.
• Dork Knight: He can fearlessly face down monsters on a weekly basis, yet — as The Mystery shows — he is reduced to a blushing, stammering mess when talking to a girl.
• Dumb Muscle: Downplayed. He is far from stupid and has proven himself to be a genuinely good person, skilled fighter and an important member of the organization. His impulsiveness and single-minded pursuit of his goals, however, can make him an unguided missile and despite being Properly Paranoid, he is still easily manipulated.
• The Dutiful Son: After learning about his mother's terminal illness, Hiromi spends her remaining few months caring for her. Doing so allows him to get a new perspective on life in the process.
• Earn Your Happy Ending: Hiromi endures a lot over the course of the series, between learning Wakabayashi had been killed and impersonated by the Deadman, the Demons Driver rapidly destroying his health, being nearly killed by Orteca, losing his mother, finding out that his commander Akaishi was Evil All Along and that he had been fighting for a lie, and Daiji's Face–Heel Turn. By the end, though, he helps save Daiji, starts up a new peacekeeping organization formed from Fenix and Weekend's remnants, even recovers physically from the effects of the Demons Driver, and once again becomes a Kamen Rider.
• First-Name Basis: Mostly everyone (besides, for example, Wakabayashi) calls him "Hiromi-san", despite his rank and age. It doesn't seem to bother him in the slightest.
• Foil: To Sakura. They're kind, hide in a tough outer shell and strive to become the hero they wanted to be since young age. Sakura succeeded by being truthful and accepting to herself. Hiromi, on the other hand, is stuck in denial and can't even own up to a crippling fear of failure, let alone how embarrassed he is of his perceived failure of a younger self.
• General Failure:
  • His demotion wasn't just accounted to his failure to transform with the Revice Driver; George mentioned that he was apparently the one leading the defense team when the Deadmans raided Fenix's research labs for the Vistamps some time prior^note as seen in The Teaser of The Movie that was double billed with Kamen Rider Saber + Kikai Sentai Zenkaiger Super Hero Senki., and he failed to stop that as well.
  • His Phlebotinum Overload from attempting to activate a double Genomix unprepared in #12 resulted in Yujiro confiscating his Demons Driver in #13 over general risk concerns for his health should he try to attempt it again.
• Gender-Blender Name: "Hiromi" is a unisex name in Japanese. This is a plot point in Juuga VS Orteca, where Rinna refuses to upgrade the Juuga Driver as she believed that Genpachiro was having an affair, due to her discovering text messages from Hiromi.
• Get A Hold Of Yourself Man: Stops an emotionally-enraged Daiji from beating his brother Ikki after he failed to save Akemi in #37.
• The Heart: He turns out to be one of the most morally upstanding characters of the show, in spite of all the hardships he faces through the series. He's had a direct hand in two Heel Face Turns, with both Daiji and George.
  • The Igarashi siblings and Vice of all people come to admire him deeply for his drive to protect others and the world, so much so that they were heartbroken at his apparent death in Episode 21. Surprisingly, Vice was the one who took it the hardest and this event became the primary catalyst for his distrust of Fenix and George specifically.
• Heroic RRoD: He's been gradually weakening with each use of the Demons Driver, both in and out of suit. #18 reveals that his body has become so weak and frail that his bodily functions are comparable to an 80-year-old.
• Heroic Wannabe: Despite George's warnings, he was the first person who tried to use the Revice Driver and was noticeably excited about the idea of laying down his life to protect the world.
• Hidden Depths: Played for Laughs. Despite sporting a serious and determined demeanor, Vice discovers in Episode 10 that he's secretly emotionally fragile, as seen when he peeks into his mind and sees Hiromi's inner self bawling his eyes out like a baby following Ikki and Daiji/Kagero's fight.
  • This is later heartbreakingly Played for Drama, when he is reduced to a complete and utter wreck at the revelation that the real Wakabayashi was Dead All Along.
• Hot-Blooded: Downplayed. While a generally cool-headed soldier, he's prone to making rash decisions to the detriment of his mission. This trait is what got him demoted in the second episode, though he's taking it in stride.
• Incurable Cough of Death: The deterioration of his health is emphasized by a persistent cough and fatigue following Fenix' attack on the Deadmans' base in #15 and #16.
• It's Personal: Guns after the Chameleon Deadman for the death of the real Wakabayashi.
• Laser-Guided Amnesia: After surviving Orteca's attack in #21, he has lost his memories of working for Fenix, but remembers his life before that, including his mother and hometown. However, DEAR GAGA Page 1 reveals him to be Faking Amnesia so that he doesn't have to go back to Fenix again.
• Locked Out of the Loop: Despite being told by his superiors he might be the cause of Daiji's mental instability, they kept the actual nature of Daiji's state a secret from him while never explicitly stating that Evil is actually Daiji's inner demon Kagero, leading him to run on his own assumption that Evil is Daiji himself.
• Made of Iron: In #21, he takes a finisher to the chest from Orteca and still manages to get up. And then there's his surviving a fall off a cliff. Keep in mind that he was untransformed during that time, and his body was now equivalent to that of an 80-year old by that point.
  • Later in the series in #44, he transforms into Demons one more time, in spite of the fact that doing so would make his condition worse, and wins against Holy Live.
• Mad Libs Catchphrase: "I will lay down my life, if it means [what he seeks to accomplish]!", most commonly "protecting the world". He abandons it when he fights Daiji in #44, after George makes clear that Hiromi can no longer treat his life as something so easily thrown away. His new line is now, "I'll devote my entire being, [what he seeks to accomplish]."
• Meaningful Name:
  • His given name contains the Japanese word for "three", mi/三 (albeit written in katakana), which subtly signifies him as the third Rider belt user of the show to appear.^note This may not have been intentional, as he was originally meant to be Killed Off for Real in episode 1.
  • Hiromi could be read as "Hero Me", referencing his strong desire to be a hero.
• My God, What Have I Done?: He becomes Demons after he learns that his attempt to use the Revice Driver in #1 may have been responsible for Daiji's supposed insanity, believing that it's his responsibility to take Evil down.
• Not Quite Dead: DEAR GAGA reveals Hiromi survived being blasted off the cliff by Orteca back in #21 despite his body being as frail as an 80-year-old man by that point. On the other hand, he's currently suffering from amnesia (or at least, pretending to be) and doesn't remember working for Fenix or being a Kamen Rider.
• Not So Above It All: As hard-edged as he is, he has his moments.
  • In #10, he mentally goes into Inelegant Blubbering after Ikki and Kagero's fight.
  • When he was bathing at Happy Spa, he wonders aloud if he should meet his mother, using the Miyagi Prefecture slang "gaga"
  • In #13, he finds Lovekov adorable. He even calls her a child when he's protecting her later-on.
  • In Part 1 of The Mystery, he falls in love with Suzu at first sight and acts awkwardly around her.
• Odd Friendship: Surprisingly, he seems to lack any distaste for non-malicious demons. He gets on with and works quite well alongside Vice while finding Lovekov cute, willing to fight Gifu juniors untransformed to protect her.
• Perpetual Frowner: His default emotion is stoicism, with restrained passion. He does get quite a few Not So Above It All moments however.
• Power-Strain Blackout: His use of the Demons Driver eventually causes him to have frequent fainting spells, due to it slowly consuming his life away.
• Properly Paranoid: He's had his own suspicions that something was wrong with Daiji due to being witness to his odd behavior and fainting spells himself. He's also Genre Savvy enough to figure out that the Igarashi siblings' parents can be in danger and has taken necessary precautions to keep them safe.
• Put on a Bus: He decides to leave for his hometown in Miyagi Prefecture after getting blasted off a cliff by Orteca in #21 for an indefinite amount of time due to his weakened physical condition and massive Broken Pedestal towards Fenix. After spending some much-needed time away from the battlefield and making peace with himself, he returns to the main series proper in #37.
• Quickly-Demoted Leader: Starts off as a commander of Fenix, but is demoted to squad leader in #2 for his blunder handling the Deadmans attack in the first episode. Though it turns out that the Wakabayashi who demoted him was actually the Chameleon Deadman, so there was no legal or hierarchical backing.
• Red Herring: The show tries really hard to pass him off as the one who stole a handful of Vistamps from Fenix HQ, and by extension the true identity of Kamen Rider Evil. He's neither, though the real thief did swipe his ID card.
• Refused by the Call: He attempted to use the Revice Driver when the Deadmans attacked in #1, but was rejected by the belt and only ended up creating a Rex Deadman.
• Sugar-and-Ice Personality: Hiromi is a serious, no-nonsense and a straight-laced professional who is also genuinely selfless and heroic with a strong sense of justice. As #10 shows, he's also quite emotionally fragile, going into Inelegant Blubbering mentally after Ikki and Kagero's fight.
• The Last Dance: His transformation in #44 has shades of this, similar to Genta suiting up as Destream; feeling unable to leave Ikki, Vice, and Sakura in the position of having to fight Daiji, Hiromi decides to put on the Demons Driver one last time to try and force his way through Daiji's cynical despair, and his initial comments to George prior to getting the Driver back makes clear that he is expecting to risk his life for it. While he manages to live through the attempt and succeed in getting Daiji to finally stand down, Hiromi's clearly in immense pain after the fact.
• Took a Level in Badass: As a kid, he was relentlessly bullied by the local kids for being a crybaby. While it took quite a bit of time to get there, he's become a capable commander of Fenix as an adult.
• Took a Level in Cynic: Hiromi's optimism erodes after the discovery of Wakabayashi's death, the Demons Driver hosting a demon, and Akaishi's true allegiance. DEAR GAGA shows that he's become so jaded from his experiences that he fakes losing his memories so that he doesn't have to go back.
• Tranquil Fury: His state in the opening of #15 after having recovered from his emotional breakdown can be described only as cold, seething anger.
• Uncertain Doom: He's last seen falling off a cliff after being hit by Orteca's attack in #21, but the landing is not shown, and the official site lists him as missing instead of confirming him as deceased. The spinoff DEAR GAGA reveals that he does indeed survive, albeit greatly weakened.
• The Unchosen One: George reveals in #19 that Hiromi was never meant to use the Demons Driver.
• Unwitting Instigator of Doom:
  • In #1, not only did he create another Deadman to make matters worse, but this very mistake is what led the intended user of the Revice Driver, Daiji, to freak out over attempting to use it and needing for it to fall into Ikki's hands.
  • #7 elaborates further on this with George and Yujiro theorizing that Daiji's Heroic BSoD as a result of his screwup was what caused Daiji's supposed insanity and Face–Heel Turn, although he wasn't told of Kagero's existence that came as a result of it.
  • Even after his Disney Death in #21, he still manages to unknowingly cause trouble in the plot, as Daiji's desire to be a worthy successor to him caused him to emulate his heroism and became rash and impatient whilst trying to remove FENIX's corruption, which made him open to Akaishi's manipulation.
• Weak, but Skilled: Despite being significantly weakened due to the Demons Driver absorbing most of his life-force, he is capable of going toe-to-toe with Holy Live, which is statistically stronger than Demons, with both skill and sheer determination.
• Workaholic: He has nothing else going on in his life besides an unhealthy attachment to his job as a member of Fenix. Not even knowing that the job itself is killing him can hold him back.
  • Subverted in DEAR GAGA. After surviving his fall from a cliff, it's shown the trauma from all those battles broke him, to the point where he fakes amnesia so that he doesn't have to return to Fenix.

Tropes exclusive to him as Kamen Rider Demons

Decide Up! Deep. (Fukaku.) Drop. (Ochiru.) Danger. (Kiki. Kamen.) Rider. Demons!

• Alliterative List: The Demons Driver's roll call, as shown in the caption.
• Arachnid Appearance and Attire: He has an asymmetrical spider web design for his armor.
• Armed Legs: Can get these from his Genomixes depending on the Vistamp and use of a Finisher.
  • Batta Vistamp gives him the Demon Bottom Higher.
  • Mogura Demons Requiem has the Demon Digzon equipped to his right foot as he does a Rider Kick.
• Badass Cape:
  • In base form, he has a small mantle-type one on his right shoulder to keep the web pattern of his suit flowing. It also hides the spider that creates his suit.
  • Imperial Demons form grants him a full-length cape.
• Beware My Stinger Tail: The Demon Ridolstinger, a scorpion tail attached to his back waist given by the Scorpion Genomix.
• Blue Is Heroic/Red Is Heroic: Blue and red are among the colors used when he's Demons and he's fighting against the Deadmans. Unfortunately...
• Cast from Lifespan: His repeated transformations with the Demons Driver have caused him to undergo Rapid Aging (making his internal organs deteriorate to the state of an eighty-year-old's), so that Akemi has to tell him to stop transforming lest it kill him.
• Dark Is Not Evil: Despite his suit's intimidating design, Demons is firmly on the side of good in Hiromi's hands.
• Extra Eyes: His helm has additional pairs of eyes called String Eye similar to an actual spider's.
• Finishing Move: By either pressing the Vistamp against the Demons Driver's screen again before hitting both Demon Knocks, or by hitting both Demon Knocks three times when using a Genomix, Demons can perform "Finishes" or "Requiems".
  • Spider Demons Finish: has three variations.
    • Demons is encaged in Spider Limbs that sprout from his back as he does a Rider Kick. Hiromi can also stack the effect and add more legs, which boosts the strength enough that it can evenly match Holy Live's Finisher.
    • Demons launches Demon String at an enemy, pulls the string towards him, and he punches and delivers a Rider Punch covered in crimson energy.
    • Demons covers his leg with red energy before performing a side kick motion. Eight red energy spider legs are then generated from Demon's leg and crush the enemy.
  • Batta Demons Requiem: Demons jumps into the air and delivers a Rider Kick enhanced by the Batta Genome's Demon Bottom Higher.
  • Mogura Demons Finish: Demons delivers a drilling Rider Punch/Thrust with the Demon Digzon equipped.
  • Mogura Demons Requiem: Demons delivers a Rider Kick with the Demon Digzon equipped to his right leg.
  • Condor Demons Finish: Demons flies into the air and uses the Demon Rumblejoker wings to fire eight bladed feather projectiles, which embed themselves in the enemy. He then performs a flying dropkick with both feet covered in purple energy, completely destroying the opponent upon impact.
  • Imperial Demons Finish: Demons bind his enemy with webs and tosses them around.
  • Komodo Dragon + Crocodile Demons Requiem: Using both the Komodo Dragonic Heat and Croco Wizarolling, Demons blasts his enemy with the Komodo Dragonic Heat before unleashing a flurry of Rider Punches and finishing with one final blast from the Komodo Dragonic Heat.
  • Imperial Demons Requiem: Demons unleashes a wave of energy, creating a spider's web that binds the enemy at its center. He then leaps into the air, crimson energy constructs of spider legs sprouting from his back and forming a drill around his leg as he unleashes a Rider Kick. Alternatively, performs a Rider Kick alongside Evil and Live, leaving behind a "50" mark after destroying their enemy.
• He's Back!: After returning, Hiromi did not become Demons again, but acted in a command role. However, once Daiji began trying to form a contract with Giff, Hiromi finally becomes Demons again, and Revice plays it up for all it's worth, with a slow-motion transformation that is given as much gravitas as some form reveals.
• Mechanical Muscles: Dubbed Geno Muscles, the Demons Driver and the red parts of Demons' suit is largely made up of this.
• Phlebotinum Overdose: In #12, attempting to add a second Genomix while having one already was too much at the time, which harms and knocks him out.
• Power Gives You Wings: The Condor Vistamp gives him a Genomix that sprouts from his back a pair of wings called the Demon Rumblejoker that grants him Flight.
• Power Limiter: The belt of the Demons Driver has another purpose besides serving as a transformation device: to stop the Spider Vistamp's power from leaking out of the Driver unrestrained. The fact that this needs to be done at all suggests Demons is much stronger than it lets on. Removing this limiter, however, will cause Hiromi to turn into a demon.
  • A potential reason is revealed via a demo of the DX Driver. Demons can apparently use several stamps at the same time and not only utilize all their individual abilities, but the corresponding requiem would use their total power. Via said demo the belt used Spider, Batta, Rex, and Lion. This is not shown in the show until Orteca uses it.
• Projectile Webbing: With the power of the Spider Genome, he can shoot webbing called Demon String to grapple onto surfaces — even upside-down — in the 3-dimensional plane, and bind enemies.
• Spider Limbs: Using Demons Finish with the Spider Vistamp has him sprout eight spider legs that encage him as he does a Rider Kick.
• Spider-Man Send-Up: A Spider-themed Rider with a red, white, and blue color scheme, and shoots webbing out of his hands to fight. His debut episode even has him use his webbing to hang upside-down (although braced against a steel beam rather than free-hanging). He also has a nemesis in the Chameleon Deadman, a lizard monster that wears white, which calls to mind Spider-Man's first supervillain in the comics, the Chameleon and his sixth supervillain, the Lizard. The use of the Condor and Scorpion Vistamps calls to mind other members of Spider-Man's supervillain rogues gallery, the Vulture and Scorpion. The use of the Mogura Vistamp calls to mind the Spider-Man (1967) version of the supervillain Mole Man.
• Super Mode: Imperial Demons form, via the Giant Spider Vistamp.
• This Is a Drill: The Demon Digzon, a drill gauntlet on his right arm given by the Mogura Genomix.
• Worf Had the Flu: As the series goes on, Demons goes from being able to defeat two Gifftexes on his own to struggling to beat Giff Juniors. This is because the Demons Driver is draining Hiromi's body and by #18, his bodily functions have deteriorated to the point of being over 80 years old.
• Wrong Context Magic:
  • Unlike Revi and Evil who have symbol marks on their chest to activate their more animalistic abilities, Demons lacks one, instead relying on the Demons Driver's Genomix function to pull off something similar by mixing other animals' characteristics into his Spider Genome. All There in the Manual reveals that Hiromi's DNA is actually fusing with the animal's DNA every time he Genomixes.
  • His Demons Driver doesn't keep the Vistamp in-use attached to itself unlike the others.
  • He also differs in his motifs. While Revice has motifs of Heisei Riders themed around various animals, Demons mostly uses Vistamps themed after the Showa Era Riders, with each creature being a kaijin they fought during their series, or the Rider themselves.
    • Batta is a grasshopper as is fitting for Ichigo, who had the same animal motif.
    • Mogura is presumably linked to the Mole Beastman, who had fought and later befriended by Amazon.
    • Condor connects to the Nasca Dopants,^note one of the Nazca lines is "The Condor" who have fought and have connections to the users who make-up the Heisei Era Kamen Rider Double, and manifests wings similar to the energy wings they generated for flight.
    • Scorpion connects to Sasori Geronimo Sr. and his son Sasori Geronimo Jr. who have both fought Kamen Rider X.
  • Unlike the Igarashi sibling Riders — whose Drivers siphon power off their inner demons — the Demons Driver actively turns Hiromi himself into a demon and directly siphons its power off his life force, causing his internal organs and bodily functions to undergo Rapid Aging. Though as shown later with George, this is purely due to Vail and not the Driver itself.

---

• Anger Born of Worry: It required a life or death situation to get him to voice his concern for Hiromi in a way that's not extremely demeaning. They both agree that's what he is like.
• No Social Skills: Self-admittedly has the communication skills and tact of a sledgehammer.
• Offscreen Moment of Awesome: Hiromi reveals in #38 that he caught onto Akaishi's plan by inspecting file records and helped evacuate all the rehab patients on the FENIX Skybase before it was destroyed by Giff.
• Poor Communication Kills: He wants to take the Demons Driver away from Hiromi, worrying that using it would kill him... yet says in a way that implies he thinks Hiromi is unworthy, leading to their rift in #19.
• Red Armband of Leadership: Wears one designating him as a Squad Leader.

Research and Development

George Karizaki

George Karizaki/Kamen Rider Demons (III)/Kamen Rider Juuga

Portrayed by: Noritaka Hamao (live), Takuma Komori (suit)
Young George Portrayed by: Jin Hiraga

Fenix's genius inventor who created the Kamen Rider System. A fanboy of Kamen Riders, he seeks to recover the Vistamps his father, Masumi Karizaki, invented 30 years ago that were stolen by the Deadmans, particularly 10 "special" ones among them. As it turns out, he picked these Vistamps for the creation of the Barid Rex Vistamp.

Initially becoming the third Kamen Rider Demons after reclaiming the Demons Driver and Spider Vistamp from Orteca, he later remodels the Chimera Driver into the Juuga Driver, using it with the Juuga Vistamp to transform into Kamen Rider Juuga.

Tropes that apply to him in general

Brilliant Scientist of Fenix

^{Click here to see young George} 

• Affectionate Nickname: He's "Kari-chan" to Vice and "Kari-san" to Sakura.
• Always Someone Better: How he feels about his relationship with his father from a scientific perspective; it isn't until he invents the Destream Driver that he begins to even feel like he's stepped out of his father's shadow. After Masumi dies for real, his need to prove himself better than and vent his spite toward Masumi mixes badly with his existing Kamen Rider obsession to push him toward remodeling the Chimera Driver into the Juuga Driver.
• Ambiguously Evil: He's initially more stand off-ish and eccentric than evil, but as the series progresses he demonstrates that his actions are definitely taken without any consideration of the morals involved. He's directly responsible for giving Kagero the power to become a Kamen Rider, gave Hiromi the Demons Driver knowing full well it would kill him with extended use, and shows no concerns whatsoever about the possibility of Aguilera dying during the Fenix invasion of the Deadman's base. When Hiromi confronts him, his only response is to mock his dreams of heroism before essentially telling him that he should keep fighting so it can finally kill him. While #21 reveals Akaishi's true allegiance, it's unknown how much in the know George is regarding his plans, or if he has entirely different goals in mind, though it's later revealed that he was forced by Akaishi to monitor the Demons Driver. #43 reveals that his more unsavory personality traits may have been due to his personality being influenced by Masumi's inner demon, which was transfused into him as a child by Masumi himself.
• Antagonistic Offspring: His goals involving Giff initially appear to pit him against Masumi, who heads Weekend, the organisation that opposes Fenix's research into Giff. While this doesn't ultimately turn out to be the case once the situation becomes dire enough, Masumi and George continue to have an extremely contentious relationship throughout the show, though it's largely on George's side due to resentment over Masumi's actions.
• Ascended Fanboy: Eventually becomes Kamen Rider Demons in #28, after taking back the Demons Driver from Orteca, and tops that by becoming Kamen Rider Juuga.
• Ax-Crazy: A little bit. When discussing the possibility of a traitor in #5, he starts making rapid movements in the middle of a conversation, explaining when asked that he's practicing how he'll snap the traitor's neck. Played much more seriously after Masumi's death, as he becomes obsessed with destroying the Rider Systems his father created, to the point that he attacks the other Riders as Juuga and refuses Daiji's offer of the simple solution of handing over their Drivers.
• Batman Gambit: George's conversation with Wakabayashi near the end of #10 heavily implies that he expected Daiji to overcome Kagero's influence the entire time, and handed the Two SiDriver over to the demon for the sake of strengthening Kamen Rider Live.
• Berserk Button: Unexpected events that are beyond his control, such as his scrapped Libera Driver somehow ending up in Sakura's hands for her use. After learning that Masumi is alive, anything having to do with him is another big one.
• Blue-and-Orange Morality: His primary motivation is to live out his dream of being a Mad Scientist with Kamen Rider obsession, specifically to develop the ultimate Rider. Everything else is beyond his notice. #46 has him backsliding into this again following his father's death: he blows off fighting against Giff to continue working on research data for Kamen Rider Juuga, and spends the following two episodes trying to destroy all other Rider systems out of his belief that the world doesn't need them anymore.
• Bunny-Ears Lawyer: He can be eccentric and sometimes petulant, but gets away with it due to him creating most of the tech Revice uses, which makes him an indispensable member of Fenix. His eccentric nature contrasts Daiji, Yujiro and Hiromi's stoic and no-nonsense personalities, much to their dismay.
• Catchphrase:
  • He's very fond of "Goddamn!"
  • Tends to utter "hey" a lot, especially when excited or dismayed. He even uses it in his battle cries upon becoming Demons.
• Character Development: George goes through quite a bit of it over the course of the series, both for good and for bad.
  • At first, George is an amoral and somewhat childish genius scientist with a deep (if superficial) affection for Kamen Riders and very little concern for the people using his equipment or much else outside of perfecting his designs. Though he can still be a jerk, he eventually realizes how much damage his attitude has done to the people around him, particularly as he grows more friendly with the Igarashi siblings. This is notable in regards to Hiromi, who he'd gleefully used as a guinea pig for the Demons Driver until it permanently damaged Hiromi's health and drove him into hiding: in #44,George becomes visibly upset at Hiromi mentioning that he has to lay down his life one more time to save Daiji.
    George: Don't ever use that phrase again. That's my condition in exchange for the Driver.
  • At the same time, it's clear that George has a lot of unresolved issues with his father as both a scientist and a person, which drives a lot of his actions and research toward the goal of surpassing Masumi. This only gets worse when George learns that Masumi both faked his death after Vail's sealing and finished the Libera Driver that George discarded; this causes George to be noticeably more petulant and difficult to work with whenever his father and Weekend are involved in a problem. Though George gets his father's recognition after inventing the Destream Driver, learning that Masumi transferred his inner demon into George as a child angers George badly enough that he refuses to see a dying Masumi until it's too late. The resultant trauma from the lack of closure, his remaining resentment toward his father, and no small amount of influence from Masumi's demon Chic all send George on a dangerous backslide from his previous growth, and he becomes obsessed with finishing the Juuga Driver to prove that he doesn't need to "rely on the power of demons", which further escalates toward him directly attacking the other Riders to destroy their belts. It takes Ikki transforming and beating George in a fight (losing his final memories of his family in the process) to finally get George to admit how badly he misses his father, regaining his previous growth.
• Conflict Ball: Downplayed. Although Giff is out of the way, George decides to start a new conflict by hunting down each of the Kamen Riders as Juuga and taking their Drivers. He even rejects Daiji when he offers to hand over the Drivers peacefully, wanting to fight him for it. That being said, he's the final catalyst for Ikki losing his memories of his family, forcing Vice to find anything that could break the contract.
• Cool Shades: Wears a big, yellow-tinted pair that adds to the general quirkiness of his appearance. He throws them away in the beginning of #47, signifying his descent into darkness, and regains them in #49, signifying his return to the light.
• The Corruptor:
  • He is responsible for giving the Two SiDriver to Kagero, as well as encouraging his rampage. Though it's heavily implied later on that he purposely did this to amplify Kagero's negative power, so that Daiji's positive power would become even greater by being forced to overcome it.
  • Giving the Demons Driver to Hiromi and pointing him in Kagero's general direction to have them fight also does not help anyone else but George himself. He also stayed quiet about the Driver's side effects until he had no other choice.
• Creative Sterility: A mild example in that George manages to come up with a number of other inventions, but Barid Rex is both his first major creation and clearly the one he pours the most time and passion into making, resulting in a Vistamp that's far more flexible than any of Revice's future upgrades. When George becomes obsessed with creating the ultimate Driver, the end result is that he just makes Barid Rex again but with higher physical stats. The reason why becomes clearer after Juuga's defeat: it and Barid Rex are both based off George's childhood drawings, and by extension his happy memories with his father before he was abandoned.
• Deadpan Snarker: George has his moments during his conversation with Vice in #7.
• Did Not See That Coming:
  • Seeing the Libera Driver in a finished state catches George completely off-guard in #11. #12 furthers this trope revealing that while he created the belt, he never got around to finishing it; in fact, it was even supposed to be scrapped, which raises more questions as to who exactly recovered it, not even mentioning who finished it. As it happens, we do learn the who eventually... though the HOW is still unrevealed at the time.
  • And it gets worse when he discovers the existence of the Rolling Vistamp. The Libera Driver being complete and in the hands of Sakura shocked him, but it was at least one of his creations. Jack Revice, on the other hand, is clearly not, and leaves him furious and snarling threats towards whoever dared to mess with his design.
• Disc-One Final Boss: George's stint as main villain ultimately amounts to a two-episode rampage, with the actual role of final boss going to Vice.
• Face–Heel Turn: With Giff's defeat in #46, George, consumed by his darker impulses, takes over as the antagonist for the next two episodes once he completes the Juuga Driver. He comes back to the heroes' side after finding the closure he needed for his father's death.
• Failed Attempt at Drama: All the glamour he tries to put on turning into Juuga is instantly torpedoed when he zaps himself trying to start up a finisher.
• Fanboy: The reason the Revice Driver and Vistamps he makes are based on past Kamen Riders is because George is a huge fan of them, particularly the Heisei Era Riders. He also carries Kamen Rider accessories and plushies on his person, and the collection of high-end Rider belts, figures, and other merch he keeps in his office would make any fan jealous. However, he's shown to have only a superficial understanding of what Kamen Riders are truly about; his willingness to manipulate unsuspecting individuals into using dangerous Drivers to create the ultimate Kamen Rider is far from the heroism that many of the Riders embody, and his pursuit of scientific progress without consideration of morality is more like the villains of the franchise than the heroes. Part of his Character Development is growing out of this shallow mindset as he shows more care for the various Riders around him and comes to regard them as people, not just tools to indulge his Rider fanboyism.
• Fantastic Racism: George slides into this after his mental breakdown, seeking to exterminate all the remaining demons and the Riders that draw on them for power. While he doesn't say it explicitly, it's clear George blames the existence of demons for having ruined his life and his relationship with his father.
• Foil: To both Hiromi and the Igarashi siblings.
  • With Hiromi: Both of them are members of Fenix, but while Hiromi is outwardly a stoic workaholic but is secretly emotionally fragile, George is outwardly a silly manchild but has a manipulative, serious side to him. Both of them are also motivated by their ideas of heroism, but whilst Hiromi idolises the concept and spirit of being a hero, George idolises past Kamen Riders and their flashier aspects, like suit design and powers.
  • With the Igarashi siblings: Ikki, Daiji, and Sakura still have two living parents and each other as a support network, while George's parents are both absent from his life and he's an only child. He also happens to share more than a few character flaws with each of the Igarashi siblings despite first appearances; he has Ikki's bad habit of hyperfocusing on one goal (the creation of Vistamps and Rider technology), Daiji's family-based inferiority complex (directed at his father instead of an older sibling) and Sakura's inability to be honest about self-doubts. This becomes more pronounced once Masumi reveals himself to be the head of Weekend; Genta and Masumi both have shady pasts connected to NOAH, but where Genta's past identity "died" and he became a reliable father to his children, Masumi's "death" caused him to disappear entirely from George's life, leaving George alone and bereft of support when he most needed it. Even the way that the Igarashis and George both got inner demons relies on receiving them thanks to their fathers, but for Ikki, Daiji, and Sakura their demons were born because Genta's Giff cells passed down to them, while George literally got his from Masumi implanting Chic into his body.
• For Science!: He leans towards this, being perfectly willing to give his Drivers to people he deems as suitable users regardless of their moral stance, all for the sake of furthering his research. #20 has him tell Hiromi that his goal is to create the ultimate Kamen Rider.
  Wakabayashi: Everything is an experiment with you, is it? But to what end?
  George: I am simply indulging in the depths of my love for Kamen Riders, nothing more.
• Geek Physiques: Averted. #4 has him working out in his office and showing off a lean but distinctly muscular build.
• Gratuitous English: He litters his speech with a lot of English words, including the occasional Foreign Cuss Word.
• Hates Their Parent: Ultimately what his relationship with his father boils down to. Though Masumi did clearly love and support him as a child, and George feels some fondness toward Masumi in turn, George also feels trapped by Masumi's legacy as a scientist and is driven to surpass him. George learning that Masumi faked his death and left George alone for most of his adolescence and adulthood only worsens things, and what little progress they make with George's creation of the Destream Driver gets undone dramatically once Masumi reveals that he implanted his own inner demon into George as a child. George's anger over this ultimately leads him to ignore Masumi even as Masumi is actively dying, which he comes to regret when his dad finally passes away. The resulting spiral keeps George from admitting how much he loves his father until it's proven that Masumi literally based his Vistamp work on George's childhood drawings.
• Hidden Heart of Gold: While he is devoted to science, George does have some compassion for the people around him, being willing to give up the Giff Vistamp to the fake Wakabayashi in return for Hiromi's safety. After researching the events of Kamen Rider Vail and NOAH, he's more willing to show this side of him, openly worrying for the Igarashi family over his experiments.
• Interim Villain: George serves as the villain in between Giff's defeat and Vice becoming the Final Boss.
• Invoked Trope: Due to being a Kamen Rider fan, he specifically designed the Revice system to incorporate as many franchise conventions as possible.
  • Phlebotinum Rebel: Not only did he design the Revice Driver to work with recovered Vistamps that the Deadmans use, he additionally made the entire system work on needing a demon's power to fight demons. This almost backfires horribly in the "very first episode'' when Hiromi's failed attempt to use the belt in an emergency results in the creation of a Rex Deadman and Daiji — who was considered the top candidate to use the Driver — being paralyzed by the thought of unleashing yet another demon, preventing him from even trying to transform.
  • Finishing Move: How can Revice safely restore a Phase 2 Deadman back into a normal human? A good old-fashioned Rider Kick.
• Just Following Orders: Claims his more dubious actions were done under strict orders from Akaishi.
• Large Ham: Less often than the resident perpetual ham Vice, but his reactions to certain things can be particularly over-the-top.
• Manchild: He's almost 30 and spends the majority of his time indulging his Kamen Rider Fanboy tendencies, and sits out the majority of #7 after Vice insults his initial design for the Jackal Genome. Crossing over into Psychopathic Manchild, his entire character arc as Juuga is also entirely driven out of this obsession and spite; when presented with the simple solution of burying all of his other creations, he simply says it's pointless if he can't kill the Igarashis — like a child making unreasonable demands out of pettiness and a lack of restraint.
• Manipulative Bastard: He takes advantage of Hiromi's sense of justice by theorizing that Kagero's creation may have been his fault, setting him up to become Kamen Rider Demons.
• Missing Mom: His mother is not mentioned for the majority of the series until #48, which shows a photo of her with Kid George.
• Nepotism: As Part 5 of The Mystery reveals, George got the job at Fenix due to his father's influence.
• Never Got to Say Goodbye: George deliberately ignores Hana's pleas to see his dying father in #44, choosing to work on the Demons Driver instead to bury his anger over Masumi implanting his inner demon into George's body as a child. When George finally decides to bite the bullet and go, he's greeted by Masumi's dead body on a medical bed.
  George: Hey—! (upon seeing his father's dead body) Daddy...?
• Nice Job Breaking It, Hero: Accidentally unleashes Masumi's inner demon Chic from him when he tries to test out the Chimera Driver. This leads to the events of Kamen Rider Revice: Battle Familia.
• No Place for Me There: Not towards himself, but towards the Igarashis, as he believes that those with Giff's cells have no place in a world of peace.
• No Sense of Personal Space: Doesn't mind getting handsy with people, even though they usually do mind.
• Older Than He Looks: He is 28 years old, but he looks like a man in his early 20s. Justified because his actor was 22 years old at the time of filming.
• Once Done, Never Forgotten: Vice dissing how the design of his version of the Jackal Genome ends up becoming this. When the Barid Rex form was designed, George deliberately didn't do anything for him because he's still upset at Vice for what he said about that design.
• Parting-Words Regret: Of sorts; George's final interaction with his father was storming off after learning that Masumi transferred his inner demon to George when the latter was a child.
• Power at a Price: All the Drivers he personally created or otherwise maintains have a catch to using them, some way or another.
  • Revice Driver/Libera Driver: releases the user's Inner Demon and gives it physical form, forcing them to constantly keep it in check. Ikki, however, is able to turn this into a strength with the Revice Driver, as he and Vice become a powerful, mutually friendly battle combination; Sakura isn't really hindered by the Libera Driver, since Lovekov is generally more docile and cooperative than Vice is and helps compensate for Sakura's lack of additional forms by acting as various weapons for her instead.
  • Two SiDriver: Allows an Inner Demon to transform into Kamen Rider Evil by possessing their host's body. This drawback becomes a non-issue when Kagero "dies" in #26, and remains so even after he revives in #44.
  • Demons Driver: An actual demon is sealed inside of it and is capable of consuming its user's lifeforce if they don't have motives matching its own. However, it's eventually revealed that the consumption of lifespan is actually an innate side effect of the Vistamp-based Rider System itself, and prolonged use by any normal human would eventually result in their own death. Until George is able to create the Mass-Produced Demons Drivers which more safely utilize the user's inner demon to transform, the Igarashi siblings and Genta are the only people capable of safely avoiding the lifespan consumption effects of the Rider System thanks to their Giff-enhanced physiologies.
  • Destream Driver: Unlike the other Drivers listed above, it doesn't require the power of a demon to use at all, but consequently requires the user to bear the brunt of the transformation's strain themselves, making it an extremely difficult Driver to use.
  • Chimera Driver: Due to not having Giff's eyes until Chic planted them in the Driver, those who use it end up mutating into a demon regardless of whether they successfully become a Rider, as shown with Shinta and Ryu.
• Red Herring: #24 shows what that he did to "unlock the full power" of the Demons Driver implies that he might have set Vail free. Revice Legacy heavily implies that it's Akaishi that set Vail free even before the series started.
• Teeth-Clenched Teamwork: Once Masumi's revealed to be alive and George actively takes a stand against Giff by working with Weekend, this is the pattern he and Masumi fall into; they're more than capable of working together when the chips are down, but George is clearly agitated and reluctant to do so every time.
• The Smart Guy: He's the scientist who maintains and designs the Drivers and Vistamps the Riders use. The only exceptions are the Vistamps Fenix sets out to recover at the start of the show, the Demons Driver, and the Vail Driver, all of which his father created.
• Smart People Play Chess: A variant with a different game, as while he's discussing his "experiment" with Kamen Rider Evil in #10, he's also playing with a Reversi board.
• Street Smart: He's the first to tell that something's up with Daiji, and that he did not seem like himself as of late and when he stole the Vistamps. He was right, as the latter had been possessed by his inner demon Kagero.
• Tall, Dark, and Handsome: His actor is one of the tallest members of the cast standing at 1.85m (around 6'1) and is very attractive, especially with his dark hair.
• Token Evil Teammate: He might be a member of Fenix and a Kamen Rider fanboy, but until the introduction of Director Akaishi, he is the only member of Fenix who has shrewd and shady qualities, contrasting (the real) Wakabayashi, Daiji, Hiromi and other soldiers who are genuinely heroic individuals with good intentions.
• Took a Level in Jerkass: Once his father dies, George noticeably begins shutting down and shutting himself out from his remaining allies, holing himself up to work on the Juuga Driver and showing clear disinterest in helping out in the fight against Giff. This escalates to an outright Face–Heel Turn upon the Driver's completion.
• Took a Level in Kindness: After researching the secret behind the Igarashi family and his father's actions as a member of NOAH, George slowly exposes more of his hidden compassion, openly becoming concerned about the Igarashi siblings' safety and coming to regret using Hiromi as a guinea pig for the Demons Driver.
• Tragic Keepsake: Keeps a book of science Masumi gave him in his childhood on his desk. While it's initially subverted due to the fact that Masumi's still alive, it takes this status again after #44 once Masumi dies at the end of that episode, and #48 adds on his collection of childhood drawings—the very same ones that Masumi used as the basis for the 10 special Vistamps.
• Unwitting Instigator of Doom: His rampage as Juuga results in Ikki having to transform into Revi, resulting in him losing his memories of his family and leading into the two-part endgame.
• Used to Be a Sweet Kid: Flashbacks reveal that he used to be a bright, Cheerful Child who loved science and was very close to his father. And then said father transferred his own inner demon into him.
• Would Hit a Girl: Does not pull his punches against Hana nor Sakura in #47, to say the very least.

Tropes exclusive to him as Kamen Rider Demons

Decide Up! Deep. (Fukaku.) Drop. (Ochiru.) Danger. (Kiki. Kamen.) Rider. Demons!

• Blue Is Heroic/Red Is Heroic: For a given definition of "heroic", although he does show more compassion over time. Either way, George sports blue and red as part of Demons' color scheme and he's thoroughly opposed to Orteca.
• Dark Is Not Evil: While George has his moments early on, he gradually loses his shady traits over the course of the series. Demons' suit sports black as part of its color scheme and has an intimidating design, but during George's tenure as Demons, he is firmly against Orteca.
• Hour of Power: His use of the Batta Genomix only lasts a short time before it completely drains him, cancelling his transformation.
• Simple, yet Awesome: For as much as he hams it up as a Rider, George’s fighting style is surprisingly practical, making good use of Demons’ Demon String to safely restrain a berserk Jack Revice and using Batta Genomix's Demon Bottom Higher to dodge around Orteca in Anomalocaris Deadman form, while simultaneously building up momentum for a more powerful attack. Were it not for Giff’s regenerative powers, he likely would have won against Orteca with little trouble.
• Spider-Man Send-Up: George has many similarities to Peter Parker, being a genius scientist who often taunts his opponents. He also tends to use the Demons suit's web-slinging abilities more often than Hiromi or Orteca, making his fighting style the closest to Spider-Man's. Both also lose a family member not long after parting with them on bad terms; while Ben's death spurred Peter to become a hero, Masumi's death sends George into a downward spiral into villainy.

Tropes exclusive to him as Kamen Rider Juuga

Juuga Driver Voiced by: Ryō Horikawa

Scramble! Tokusa no idenshi tsuyoki kokorozashi! Hazero! Hoero! Choetsuseyo!^note Ten genomes in tow with one cocky ambition! Burst out! Howl up! Transcend above! Kamen Rider Juuga! Go over.

• All Your Powers Combined: The Juuga Vistamp contains the combined powers of the ten "special" Vistamps that Revice uses for his Barid Rex form. The intake port on its left can also be used to inject the Juuga Driver with even more power from a specific Vistamp, whereupon it is revealed that by doing so, Juuga can also use the powers of all Heisei Riders.
• Barefisted Monk: Fights without wielding any weapons.
• Corrupted Character Copy: Of Kuuga essentially, particularly his Ultimate Kuuga form. Kuuga fought for everyone's smiles, George is using Juuga to fight for his own, which incidentally also makes Juuga a copy of Another Kuuga, an Evil Knockoff of Kuuga.
• Dark Is Evil: Juuga has a mostly black bodysuit, and is a villainous Rider.
• Dark Is Not Evil: Whenever Juuga reappears during events set after the series.
• Evil Knockoff: Of both Ultimate Kuuga and Revi Barid Rex, with the color scheme of the former and a costume remodeled from the latter. Juuga's abilities are just Barid Rex's dialed up to the power level of a final boss.
• Finishing Move: Like Chimera and Daimon, Juuga has different types depending on the number of times he raises and lowers the Juuga driver's buckle.
  • Impulse Genomedge: Has two variations:
    • Juuga dashes around the enemy, striking from all directions before finishing with a Rider Kick.
    • Juuga performs a side kick with his leg encased in energy in the shape of a T-Rex’s head and jaws.
  • Crush Genomedge: Juuga conjures a green tornado and launches it at the enemy.
  • Amazing Finish: Has two variations:
    • Juuga creates red pterodactyl wings from his back, wreathing himself in flames before performing a charging attack on the enemy. He then follows up with a purple brachiosaurus head energy construct that knocks the enemy into the air and slams them back down to the ground, before finishing with a heel drop encased in a red mammoth leg construct.
    • Juuga charges his leg with gold energy before unleashing a spinning jump-kick to the enemy.
  • Attack: Used when a Vistamp is placed in the Juuga Driver's intake port; enables Juuga to wield the power of the Rider incorporated into the stamp. The prefix changes depending on the Vistamp inserted.
    • Lion Mighty Attack: The Lion Vistamp's finisher; based on the Mighty Kick.
    • Megalodon Dimension Attack: The Megalodon Vistamp's finisher; based on the Dimension Kick.
    • Eagle Maximum Attack: The Eagle Vistamp's finisher; based on the Maximum Drive.
    • Planarian Itteiyo^note "Go for it" Attack: The Planarian Vistamp's finisher; based on the Shingou Ax's finishers. After a short delay using the sounds from the Shingou Ax, Juuga summons an apparition of the Break Gunner to fire on the target before finishing them off with purple slashes from another apparition of the Ax itself.
    • Chameleon Signal Attack: The Chameleon Vistamp's finisher; based on the Signal Bikes.
• Irony: Despite George's obvious obsession with surpassing Kuuga specifically in Juuga's design, none of the names for its individual parts reference Kuuga past its Amazing forms, even though Ultimate, Rising Ultimate, and Super Rising Ultimate all exist. Keep in mind that before Kamen Rider Zi-O, Kuuga was considered to be the strongest Rider across the whole franchise in terms of raw strength because of Super Rising Ultimate.
• Meaningful Name:
  • His name is a portmanteau of juu (十, Japanese for "ten") and "Kuuga", a reference to him being a Kuuga-inspired form using the power of ten Vistamps. Funnily enough, Noritaka Hamao was born on November 26, 1999, a couple of months shy of Kuuga's premiere.
  • Juu can also mean "Beast" (獣) in Japanese, and Juuga has the power of ten beasts.
• Mythology Gag: If one looks closely, Juuga's design references Ultimate Kuuga without the red eyes, which fits in with the Dark Is Evil motif.
• Skilled And Strong: Juuga’s raw strength combined with George’s genius intellect makes him a threat to anyone he designates as a target.
• Stealth Pun:
  • As the kuu part of Kuuga's name is pronounced the same way as "nine" in Japanese (九), Juuga replacing kuu with juu, Japanese for "ten", carries the hidden meaning that he's meant to be a Rider that surpasses even Kuuga.
  • Juu can mean "filled" in Japanese (充), making Juuga's name mean "Filled-self" (充我) in contrast to Kuuga meaning "Clear-self" (空我).
• Superior Successor: Specifically to Chimera and Daimon but also to all of the other Riders as well. Juuga’s powers are the most refined among the Kamen Riders of the series and effortlessly defeat even those who are using late series power ups.
• Wrong Context Magic: Allegedly the only Kamen Rider in-series that doesn't rely on any form of demon-based powers at all; as such George believes he's The Only One worthy of being humanity's protector.

Others

Akemi Mikoshiba

Akemi Mikoshiba/Giffdemos (Red)

Portrayed by: Sayaka Fujioka (live), Suzuka Usami (suit)

Akemi's Giffdemos form

Fenix's chief medical officer.

---

• Blade Below the Shoulder: As Giffdemos, she uses a sword protruding from her left forearm called Despetia.
• Damsel in Distress: Zigzagged. In #26 she's overpowered and taken hostage by Kagero, forcing George to surrender the Crow Vistamp; #33 has her initially managing to free herself after Akaishi takes her hostage, only to get captured again after he breaks her spirit in #34.
• Despair Event Horizon: Whatever Akaishi showed her is enough to drive her to giving up on humanity and volunteering to be turned into Giffdemos.
• Face–Monster Turn: Transformed into Giffdemos by Akaishi and Giff in order to attack the Riders, although by that point she had already given up and agreed to be subservient to Giff.
• Foil: To Chigusa; both being Fenix operatives who discover the dark secrets of the organization they serve, with Chigusa becoming a double agent for the Deadmans while Akemi remains with Fenix. Their fate also works differently, as Chigusa was killed off after she was stamped with the Giff Stamp by Orteca and she was taken over by the Gifftarian, Akemi was turned by Giff into the Giffdemos out of despair and eventually killed by Akaishi.
• In the Back: Is finally killed when Akaishi blasts her from behind.
• Last Words: To Daiji, before succumbing to her wounds:
  "Don't let your righteousness... drive you to lonesomeness."
• The Lost Lenore: While it's ambiguous as to whether their relationship was of a romantic nature or not, her death is the trigger that causes Daiji to turn against his family.
• Must Have Caffeine: She uses a lot of energy drinks, if the trash can filled to the brim with empty cans and bottles is any indication.
• O.O.C. Is Serious Business: After Akaishi tells her the truth about Giff, the shock of it causes her to become a lot more taciturn, rarely speaking.
• Proper Tights with a Skirt: Wears black tights with a black pencil skirt under her lab coat, which adds to her mature air.
• Red and Black and Evil All Over: Her Giffdemos form is red plating on top of a black body.
• She Knows Too Much: Is supposedly attacked by Gifftarians for discovering Akaishi's personal Vistamp shelf.
• Shock and Awe: Can produce lightning from her palms to injure her targets.
• Uncertain Doom: Akaishi does something to her when she comes across his personal Vistamp shelf in #32. Given that it involved Gifftarians being summoned it can't have been pleasant. The next episode reveals that she was merely held hostage.
• Virtuous Character Copy: According to director Teruaki Sugihara, she's modelled after Shion Karanomori from Psycho-Pass, minus the amorality of the character she was based on.
• What the Hell, Hero?: She verbally rips Hiromi a new one for his recklessness in using the Demons Driver due to the havoc it wreaks on his body, forbidding him from transforming again.

Demons Driver

Portrayed by: Kenjiro Tsuda (voice)

Let me... feast on... your life...!

The Transformation Trinket of Kamen Rider Demons, developed by George's father Masumi Karizaki. It eventually awakens to a form of sentience in episode 19, while episode 20 reveals this is due to it containing an actual demon. Episode 25 reveals the demon's name to be Vail, who has plans of his own...

For tropes pertaining to Vail himself, see his section under his and Genta's page.

---

• Deal with the Devil: Done literally, as its activation for transformation has it declaring "Deal." Fittingly, it has a habit of burning its users.
• Evil Is Not a Toy: As the series goes on, the Demons Driver and the demon within it turn out to be far more dangerous than anyone thought when it was first introduced. Subverted subsequently as George's further modifications allows it to use its wearer's own inner demon in place of Vail, which makes it much less harmful and safe enough for mass-manufacturing and the public's use.
• Evil Laugh: Prone to doing this when it's enjoying itself.
• Evil Sounds Deep: Speaks in a deep, husky voice, courtesy of its voice actor. Appropriately enough, the demon within it enjoys messing with and screwing over the Driver's users for his own sadistic enjoyment.
• Evil Weapon: A demon named Vail is inside the Demons Driver, and he's actively sadistic and prone to screwing over his users for his own enjoyment.
• The Gloves Come Off:
  • A very dark example; it's a Sadist targeting innocent people and diverts its power towards slowly killing Hiromi, only going all out when Orteca picks it up with equally murderous intent.
  • Episode 24 reveals this was still downplayed, as while it let Orteca do a double Genomix, it still held itself back from allowing him to do a triple Genomix.
• Haunted Technology: As it turns out, the Demons Driver is the prison of a demon named Vail.
• Horror Hunger: Subverted. The Driver feeds on Hiromi's lifeforce, but this is not for sustenance or power. It simply wanted to do it. When Orteca steals the Demons Driver, it drops the facade entirely and lets him use more of its potential with psychotic glee. This is pretty much gone after further upgrades uses its wearer's non-sentient inner demon in place of Vail.
• It Can Think: Being the first Driver in the series that can think and speak for itself, it awakens in episode 19, demanding Hiromi to transform for it to consume his life force.
• Leaking Can of Evil: Despite being sealed in the Demons Driver, the demon is still able to effect both the Driver and its user. It can prevent the user from using its full strength and even drain their lifeforce.
• Living MacGuffin: The only Driver in the series so far that is actually alive.
• Meaningful Name: The Demons Driver's name could be interpreted as Demon's Driver, as in a Driver possessed by a demon. The literal interpretation of it being a driver for multiple demons also foreshadows it becoming a mass-produced Driver powered by the users' own inner demons.
• Mechanical Abomination: While a living being, the demon has a taste for machinery. Proof that he exists still seeps through, but it's cleverly disguised as parts that either are or resemble nanotechnology, haphazard wiring, and clunky mechanical plating.
• Obviously Evil: Even before it reveals its sentience, there are many signs that the Demons Driver contains a dark secret:
  • It has red Mechanical Muscles that make it both resemble a time bomb and give it a visceral look much like the Gifftexes' Deadman forms.
  • When a stamp is placed on the Demons Red Pad on top, the driver announces "Deal", suggesting the user is making a deal with the Driver itself.
  • Its transformation sounds are much darker in tone compared to the other Drivers; the standby loop is an ominous Ethereal Choir, while the actual transformation announcement has a second, deeper voice in the background and outright says "danger" at one point.
• Permanent Placeholder: Invoked In-Universe. The Driver was initially voiced by Vail because he was the Demon living within it. Despite his absence from it beyond going independent through Giff, the Demons Driver (and all the subsequent mass-produced copies of it) continues to use his voice. Even the Kuwagata Vistamp made for Over Demons is voiced by him, despite him having completely no connection to the Super Mode.
• Power Limiter: On top of the belt strap shackling its true strength, the Driver restrains and devours anyone that doesn't go along with its true personality. Orteca, being The Sociopath, has no problems getting it to make The Gloves Come Off...and then it reveals it was still holding back and was just playing around with Orteca.
• Replacement Goldfish: Episode 34 reveals that after Vail had gone independent, George has modified it to be empowered by its wearer's own inner demon as a substitute, which was why he was able to transform without Vail. Akaishi believes this makes it a suitable mass-produced weapon for the public's use, however.
• Sadist: Attempts to murder Hiromi for its own amusement and is borderline euphoric when Orteca picks it up, intent on using it for evil.
• Sealed Evil in a Can: The Driver contains a demon named Vail inside of it that steals Hiromi's life force each time it is used. This is because he was sealed inside of it so he could be beaten without Genta having to die. He finally escapes in episode 24, with it being implied whatever George did to "unlock its true power" was responsible.
