Takumi Inui

Takumi Inui/Kamen Rider Faiz/Wolf Orphnoch/Kamen Rider Next Faiz

Portrayed by: Kento Handa (live), Seiji Takaiwa (suit)

^{WARNING: MAJOR SPOILERS}

A snarky delinquent whom Mari came across by chance while chased by Orphnochs. He becomes the primary user of the Faiz Gear, and the one best-suited to using its multiple functions. Later revealed to be the Wolf Orphnoch.

Tropes that apply to him in general

• The Aloner: At first he doesn't enjoy Mari and Keitaro, preferring to act alone. Over time, he starts to accept their company and appreciate his friends.
• Astonishingly Appropriate Appearance: His haircut is a style commonly referred to as a wolf cut. Which makes it an excellent portent of Takumi's Wolf Orphnoch form.
• Blood Knight: Mild example, he grew to enjoy being Faiz.
• Boomerang Bigot: He had a time of wanting to kill all Orphnochs despite being one himself. This can be justified, every Orphnoch he met has either killing everyone around him, or was in their human form the entire time. Not to mention the fact that he hated his Orphnoch transformation due to misunderstandings.
• Breakout Character: Of the early Heisei Rider's Takumi is by far one of the most prominent and would make several complete returns (meaning not just suit or voice only but Kento Handa returning in a major capacity) down the line playing a major role in Kamen Rider Taisen, a big supporting role in Super Hero Taisen GP and being the Decoy Protagonist of Kamen Rider 4 despite it being a special based off Kamen Rider Drive. He also goes on to appear in Zi-O and is the first Heisei Phase 1 Rider to have an anniversary special. He is also constantly ranks in the top 5 Riders of any era on official polls.
• The Call Knows Where You Live: Refused to have anything to do with the Mari in the beginning, but several unintended encounters with Orphnochs and the belt being stolen and used by someone later, finally decides to assume the role of Faiz after seeing just how important that duty was, swearing to prevent it from being stolen.
• Catchphrase: Not in the series, but his speech showing just how serious he is about protecting people has become iconic to him, having him declare it in many crossovers and game appearances.
  I don't have dreams. But you know, I can protect them.
• Character Tic: His wrist flick, which he uses to either taunt opponents, start a battle or signal that he's about to do something awesome. He also kneels before every kick finisher^note Mainly to attach the Faiz Pointer on his leg, and only uses Flying Side Kicks (The iconic Rider Kick style) for his kick finishers. These allow the viewers to know that it's Takumi wearing the suit and not anyone else.
• Contrasting Sequel Main Character: The first major example in the franchise. While Yusuke, Shoichi (the previous Rider protagonist made by Toshiki Inoue) and Shinji are all traditionally heroic types, Takumi is an abrasive Ineffectual Loner and Jerk with a Heart of Gold who even briefly turns to the dark side at one point.
• Deadpan Snarker: He even says it in his nature to be sarcastic.
• Deal with the Devil: He joins Lucky Clover to get Smart Brain to save Mari.
• Death Seeker:
  • When he was tricked into thinking he attacked the Ryusei School reunion, he actively tries to get Kiba to kill him.
  • Played straight in the alternate continuity, Kamen Rider Taisen, where due to not being able to save Kusaka and his friends, he wonders if he deserves to live.
  • Completely inverted in Kamen Rider Yongou, where he ACTUALLY died during his series' ending. Due to being revived again, he wants some way to have everyone live, thus creating the time loops. In the end, even if he doesn't want to die again, Takumi destroys the time alteration machine.
• Defrosting Ice King: At the beginning of the series, he was as rude as possible and tried to distance himself from Mari and Keitaro, only living at Keitaro's house as he was forced too. As the series goes on, he's noticeably less aggressive and more involved with his friends.
• Face Death with Dignity: He knows that his day as an Orphnoch is numbered, but he's content with making full use of his remaining life. Reminding Kiba about this led to his decision to pull a Redemption Equals Death.
• Face–Heel Turn: He had done this twice after he revealed his Orphnoch form in the series before he became a Death Seeker and again in a brief moment during the Kamen Rider Taisen incident. In fact he is the first main rider to have fell from grace (albeit temporarily), followed by Tsukasa Kadoya and Aruto Hiden.
• Fake Memories: In the movie, he sustained a head injury that lead to him becoming amnesiac, so the former Smart Brain scientist who saved him, renamed him Takeshi and gave him false memories in hoping he could take care of Mina.
• Heel–Face Turn: After he finally get over from his own crisis, he resolves to become the main wearer of the Faiz Gear once again and returning to his allies for good.
• The Hero: Takumi is the primary user of Kamen Rider Faiz, although he sometimes gets overshadowed at first due to the vast majority of characters. Becomes less prominent as he became serious about being a Kamen Rider.
• The Hero Dies: Not in the main series, but it's heavily implied at the end that Takumi's days are highly numbered as a result of his Orphnoch body breaking down. Though he's content with as he has learned what's valuable in life isn't its length, but what's inside it, something he explained to Kiba to get him back to his senses. The Kamen Rider 4 miniseries implied that he passes away sometime after the final episode, but the events of Paradise Regained finally subverts this, as he was given enough therapy after he secretly sided with the re-emerged Smart Brain at the moment he was picked up upon his near death prior to the events of the movie.
• Heroic BSoD: Twice, once when he is rescued by Yuka. After he finds out that she is an Orphnoch, and questions if other Orphnoch aren't complete monsters, making him unable to fight. He gets over it, as he realizes that he should only attack those attacking humans. The second time is when he couldn't protect Mari from Sawada, causing her death. This is only further when he is forced to transform in front of his friends and have them be scared of him for a few episodes. It got worse again, when he was tricked into thinking he attacked the Ryusei School reunion, causing him to be a Death Seeker. Then, it happened a third time in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai via Retcon to have Kusaka die in Takumi's arms, leading to him suffering a ten year BSOD that ends up getting snapped out with thanks to Kensuke Jin, Kamen Rider X.
• He Who Fights Monsters: Played Literally. Takumi himself is the Wolf Orphnoch
• Hidden Heart of Gold: It is later revealed he acts the way he does because he is scared of himself and attempts to isolate himself from people so he can't hurt them.
• Hunter of His Own Kind: Takumi is actually the wolf Orphnoch.
• Ineffectual Loner: Tries several times to get away from Mari and the rest throughout the first arcs and throughout the series out of both being very antisocial and due to a misguided sense of protecting others, but it doesn't work. As it turns out, this is because he was afraid of hurting people and himself when their relationship inevitably ends.
• The Kirk: He's not too keen on friendship as his friends are, but he tries to be the mediator to his more stoic and emotional friends.
• Leitmotif: "Double Standard", which describes his situation before the series and thanks to Mari, how much it's changed since he now has something to live for.
• Meaningful Name: "Inui" contains the character for "dog" (Takumi is the Wolf Orphnoch.)
• Our Werewolves Are Different: He's the Wolf Orphnoch who died as a human and came back as a wolf man, with all the power that comes with it.
• Running Gag: Despite his Animal Motif being canines, he is called a Nekojita (Cat-Tongue) by Mari as he has trouble eating hot food.
• The Slacker: He notes he has no dream and just wants to travel around. After ten episodes worth of Character Development, he takes this slacker attitude in a very positive direction.
  Takumi: You know, I don't have dreams. But I can protect the dreams of others.
• The Snark Knight: Very heavily. He's very apathetic towards everyone on the surface, but he's afraid of becoming close to people. When the time comes, despite his cynicism, he'll always do what he thinks is right.
• Tsundere: A good case can be made for him. He is pretty snarky to everyone, but it's only a facade to hide a Hidden Heart of Gold because he's scared of hurting people. He grows nicer to his friends as the series goes on.
• Wolf Man: A humanoid wolf as the Wolf Orphnoch.
• Vocal Evolution: His voice gets deeper with each returning appearance after the series due to his actor aging, with his performance in Paradise Regained sounding completely different from the series.

Tropes exclusive to him as Kamen Rider Faiz

Standing By...COMPLETE!

• 555: Obviously. It's a pun on "Phi", "Fives" and "Faiz." Hilariously enough, 555 is a possible emergency number for Japan, meaning that every time he transforms he's literally dialing an emergency phone number for help... from himself.
• Artificial Stupidity: Due to the fact that its only priority is "Protect Mari" Auto Vajin initially doesn't do a very good job at protecting TAKUMI. It eventually becomes a reliable ally to him even performing a Heroic Sacrifice in the finale of both the series and the movie.
• Brought to You by the Letter "S": It's noticeably the Greek Letter Phi.
• Cool Bike: Auto Vajin's Vehicle Mode his Faiz's personal motorcycle. It can drive by itself and has armor made from a similar material as the Rider Gears.
• Finishing Move: Whenever Faiz inserts a Mission Memory into his gear and presses Enter on the Faiz Driver, he executes an "Exceed Charge" finisher.
  • Crimson Smash: A Rider Kick that manifests as a red drill piercing the Orphnoch.
    • Axel Crimson Smash: A variant augmented by the Super-Speed of Axel form.
    • Blaster Crimson Smash: Another variant with increased power from Blaster form.
  • Grand Impact: A Rider Punch with the Faiz Shot.
    • Axel Grand Impact: A variant augmented with Super-Speed.
  • Sparkle Cut: A Rider Slash that powers up the Faiz Edge, traps the enemy with a Sword Beam and finishes it off with a powerful slice.
    • Axel Sparkle Cut: A Super-Speed-boosted variant.
  • Faiz Blaster Sword Mode: "Photon Breaker", which coats the Faiz Blaster in Photon Blood energy for a powerful slash.
  • Faiz Blaster Gun Mode: "Photon Buster", which shoots out a massive beam from the Faiz Blaster.
• Gatling Good: Auto Vajin's Buster Wheel in Battle Mode is this. It can fire bullets rapidly from its front wheel.
• Handguns: Faiz Phone. Notably one of the few examples where the Transformation Trinket doubles as a weapon.
• Hour of Power: Axel Form only lasts for ten seconds before Faiz reverts to normal.
• Jack of All Stats: Faiz Form. Also this among the three Rider Gears, as the Faiz gear is the least powerful, but has multiple functions plus is the least taxing towards its Orphnoch users, if still will eventually kill them through continued usage.
• Laser Blade: Faiz Edge is basically a Lightsaber like weapon whose blade is made of Sol Glass. It damages it's opponents not caused by the blade's sharpness alone and the energy it discharges once in contact with the target.
• Law of Chromatic Superiority: Not only is he the main Rider with Red as a notable secondary color, his Super Mode Blaster Form drives it home by flooding his suit with red Photon Blood.
• Lightning Bruiser: Axel Form increases Faiz's power, speed, and defense, allowing Faiz to move at the speed of sound. The form can easily overpower high speed Orphnoch, with the power to destroy several at once, and can tank damage from almost any Orphnoch except Dragon. The drawback, like most forms that fit this mold, is that it has a 10-second time limit.
• Logical Weakness: As Paradise Regained demonstrates, Faiz Axel does not come with increased traction for Required Secondary Powers. Consequently, a mere bottle of vitamin drink is enough to save a few Orphnochs from being hit with an Axel Crimson Smash when it falls to the ground and Takumi slips on the resulting stain.
• Mid-Season Upgrade: Midway through the season (episode 21: Accelerating Spirits), Kaixa gives Takumi the gadget that allows him to transform into Axel Form, his Lightning Bruiser form for the series and his strongest powerup until he gets Blaster Form.
• Mini-Mecha: Auto Vajin when transformed into Battle Mode.
• Power Fist: The SB-555C Faiz Shot was designed for specific compatibility with the Faiz Mission Memory, transforming into an energy powered knuckle-duster Faiz can use for his Grand Impact Rider Punch attack. With Axel Form, he can use his enhanced speed to punch multiple enemies while running through them.
• Protagonist Power-Up Privileges: The reason he got Axel form was because Kusaka gave him the device, for some reason. He only gained access to Blaster Form because he was mailed the Faiz Blaster.
• Shoulder Cannon: Faiz in Blaster Form has this, the Bloody Cannons.
• Super Mode: Blaster Form is his final ultimate form in the series, first seen in the movie before appearing in the show during episode thirty-nine.
• Super-Speed: Axel Form gives him the speed of sound, but only for 10 seconds.
• Swiss-Army Weapon: Faiz Blaster, which has the Blade and Blaster Modes aside from being the briefcase which commands every other function of the Faiz Blaster form.
• Threatening Shark: Aside from the Phi and Wolf motifs, Faiz has this as a secondary motif. This is revealed in the Kamen Rider Decade Net Movies, and can be seen in the little fangs on his mouthplate.
• Transforming Mecha: Auto-Vajin, his Cool Bike which not only looks cool and goes fast, but also houses all of his gear and can even transform into a Mini-Mecha in a pinch.

Mari Sonoda

Mari Sonoda//Wildcat Orphnoch

Portrayed by: Yuria Haga, Aoi Yūki (young)

A member of the Ryusei School entrusted with the Faiz Gear by her foster father, which she gives to Takumi after finding she is unable to use it herself. She is turned into the Wildcat Orphnoch during the events of Paradise Regained.

---

• Back from the Dead: She dies twice but gets brought back both times.
• Cat/Dog Dichotomy: She and Takumi have that dynamic, Especially after Paradise Regained.
• Determinator: She has her moments. Like trying to transform into Faiz, despite knowing it won't work on her.
• Dude Magnet: She has three people after her. Kusaka and Sawada have loved her since childhood. While Kaido gets a crush on her as well.
• Horrible Judge of Character: It actually cost her life once. Later zigzagged when Sawada has a change of heart
• Leitmotif: "Kaban" (Bag), which is about her entrusting her future to Takumi.
• Oblivious to Love: She never knew Kusaka and Sawada liked her since childhood, despite everyone else seemed to know.
• Rebel Leader: In Paradise Lost, she's one of the leaders of the human resistance to the Orphnochs, who have succeeded in wiping out most of humanity.
• Say My Name: Shouts "Takumi" quite often.
• Tsundere: She and Takumi share a lot of Belligerent Sexual Tension.

Keitaro Kikuchi

Keitaro Kikuchi

Portrayed by: Ken Mizorogi

His family runs a dry cleaning service and he houses some of the crew.

---

• Allergic to Evil: Well, not quite "evil", per se. The instances where he sneezes and says he's allergic to people with "bad hearts"? There's an Orphnoch nearby. Yes, that applied to Takumi the first time they met as well.
• Butt-Monkey: In episode 41 at least. The fact it's presented as a comedy moment makes it even worse.
• For Happiness: The philosophy behind why he cleans clothes, and everything else he does, is because he wants to make the world happy.
• Nice Guy: He's this through and through, compared to Takumi's Jerk with a Heart of Gold.
• Non-Action Guy: Since he can't use the Faiz belt, he's relegated to the sidelines.
• Refused by the Call: Tried to use the Faiz belt once. Since he's a normal human, it rejected him.
• Star-Crossed Lovers: With Yuka. Due to a lack of communication and her also being enamoured with Kaido, they spend most of the series unaware they're each others online pen pals. And when they finally do get together, it isn't long before Yuka gets killed, leaving Keitaro with no idea what happened to her and the belief she left him.
• Took a Level in Badass: In the movie where he gets a chance to transform into Kaixa and defeat an Orphnoch, and managed to live afterwards.

Masato Kusaka

Masato Kusaka/Kamen Rider Kaixa

Portrayed by: Kohei Murakami (live), Makoto Ito (suit)

A man whose one purpose in life is Mari's love, and he'll do anything to have it. Since all our heroes are quite close to Mari, this causes... problems, not helped by the fact that even without that he's an unrepentant jerkass. The primary user of the Kaixa Gear.

Tropes that apply to him in general

• Adaptational Villainy: Kusaka was never a good guy in the first place in the series, but his counterpart from the non-canon novels is far worse and crosses lines he never would, namely, violently raping Mari at one point.
• All Love Is Unrequited: He was in love with Mari since childhood, she never knew till he flat out told her. And at the end she seemed more interested in Kiba and later Takumi. This doesn't end well for him.
• Asshole Victim: His death at Kiba's hands is quite brutal, but it's hard to say he didn't deserve it given how much he had done to sabotage his and Takumi's lives out of selfish possessiveness.
• Because You Were Nice to Me: When he was a child, Mari defended him from a group of bullies. This led to him developing a lifelong obsession with her.
• Breakout Character: Despite his abhorrent behaviour (and in many ways because of it), Kusaka has proven to be quite the popular character with fans, having made multiple appearances in crossovers over the years despite his death in the original series.
• The Bully: Despite being a bully victim himself as a child, Kusaka himself is a literal bully to anyone who he doesn't like. He intimidates Takumi behind closed doors either for getting in the way between him and Mari, or just seeing him as an eyesore.
• Character Tic:
  • Wiping his hands with hand wipes when out of Gear, or wiping his hands when in Gear. Takumi lampshades it and snarks if Kusaka is a germaphobe. It's a compulsion Kusaka developed after he imagined he had spilled blood on the night of the Ryusei School reunion.
  • Occasionally, he'll adjust his collar while transformed.
  • All his Rider Kicks are double dropkicks.
• The Charmer: As nasty as he is underneath, Kusaka is really good at getting others to like him and view him as a Nice Guy. For a time he had everyone around his thumb. Even at his death, Keitaro and Mari didn't completely understand how much of a bastard he was.
• Dead All Along: The Kusaka in Paradise Regained turned out to be an android copy of the real Kusaka, who remains dead to this day, thus rendering the time alterations in Zi-O that involved Kusaka's appearances moot.
• Declaration of Protection: Towards Mari, and he reacts with extreme violence if he thinks you are planning to do anything to her. Or be next to be.
• Deconstructed Character Archetype: Of the usual secondary Rider tropes. Unlike his predecessors, and successors, who are either straight-up heroes like the main riders or started off as anti-heroes who later Took a Level in Kindness via Character Development, Kusaka is voided of these traits and is a Nominal Hero at best, from the start till the end.
• Demoted to Extra: He gets very little to do in Paradise Lost and is dead before the climax, with Keitaro becoming the one who uses the Kaixa Gear after. It's especially glaring since the film features a character with a very similar personality to him named Mizuhara, whose role Kusaka could have easily filled.
• Died in Your Arms Tonight: Kusaka in the alternate version of his death in Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai on Takumi's arms, asking him why he has to die when someone like Takumi with nothing to protect lives on.
• Evil Hero: His duty as a Rider is to protect humans from Orphnochs, but Kusaka is ruthless to anyone he dislikes, especially an Orphnoch. However, he does show some concern towards innocent civilians, and felt grief upon watching Hanagata succumb to his condition as an Orphnoch.
• Evil Versus Evil: His backstabbing, scheming tendencies causing SO MANY problems, he might as well be a Kaijin himself. He refuses to see the human side of Orphnochs even when some are genuinely good people, including Takumi himself. Even after he's killed before the last few episodes, it's pretty clear that the heroes are now mostly dealing with the fallout of his constant sabotage of their efforts to unite, most notably Kiba's turn to the dark side, which makes his death by hands of the man he more or less psychologically tortured EXTREMELY karmic.
• Fantastic Racism: He does not respect, care, or treat Orphnoch as normal human beings. While most of them were either a Monster of the Week, he sees the innocent ones as lesser beings that deserve to be murdered.
• Faux Affably Evil: Kusaka looks like a decent guy on the surface when he's anything but. He doesn't hesitate to drop the act if you come between him and Mari, as Takumi learned firsthand. He wants all Orphnochs eliminated completely, and even looks down on both Takumi and Kiba for being Orphnochs.
• Final Solution: He may be willing to work with other Orphnochs like Kiba or Takumi, but in the end he plans to kill every single one if it's ever within his reach to do so.
• Foil: To Takumi. Takumi is rough around the edges and is a Jerk with a Heart of Gold, while Kusaka is superficially charming but is a Jerk with a Heart of Jerk.
• Freudian Excuse: Was bullied heavily in an orphanage, with only Mari standing up for him. Likewise, Kusaka's horrific past with the Dragon Orphnoch did not do him any favors.
• The Friend Nobody Likes: At least in regards to his "allies" that actually know he's a Manipulative Bastard.
• Hate Sink: He is a generally unlikeable person who manipulates others into thinking he's a charming Anti-Hero, and will try to execute any who stand in his way. Slightly zigzagged though, at least when seeing his concern for innocent bystanders, as well as care for his orphanage classmates.
• The Heavy: One of the reasons the conflict takes so long to resolve is because of Kusaka worsening the relations between humans and Orphnochs.
• Hypocrite: Proclaims that Orphnochs are inherently inhuman inside and out, yet is more than capable of cruelty.
• Humans Are the Real Monsters: He is self-entitled, petty, and spiteful.
• It's All About Me: THE defining aspect of his character, to the point of it being a meme.
• Jerk with a Heart of Jerk: While his predecessors and many successors in the Secondary Rider line are more of Jerk with a Heart of Gold, he's so far the first of said category to be a full blown Jerkass. It wouldn't be until Mitsuzane Kureshima that we'd get another like him (the latter is more of a Tertiary Rider). Curiously, Mitsuzane shared many traits with him.
• Karma Houdini Warranty: No matter the continuity, he never completely gets away with what he does. Sooner or later, his luck finally runs out. Even in Kamen Rider Zi-O, where he is less vicious, he comes dangerously close to getting his neck snapped again.
• Karmic Death: Throughout most of the show, he'd been sabotaging the potential friendship of Takumi and Kiba, and subsequently, any chance of a united front against Smart Brain, just for his own ends, also torturing both about their supposed inherent inhumanity. Ultimately, Kusaka is murdered by Kiba, who ended up snapping from being treated cruelly by other people like Kusaka. And Kiba does the deed with the Kaixa Gear as well. Moreover, he dies alone, forced to watch Mari from afar
  • In the Faiz novel, his stalkerish behavior towards and rape of Mari gets paid back by Kiba literally ripping him limb-from-limb and his getting "taken in" by his own Stalker with a Crush, Saya Kimura, very much in the fashion of Misery.
• Love Makes You Crazy: His unhinged obsession towards Mari, which borders onto an Oedipus complex.
• Manipulative Bastard: A very excellent social manipulator, capable of getting others to like him and keeping them oblivious from his machinations as he does everything in his power to break apart Takumi and Kiba's friendship and keep humans and Orphnochs hostile to each other.
• Neck Snap: He gets dealt this in his in-series death before being left to die
• Out-of-Character Moment: Gave Takumi the Axel Watch for absolutely no reason stated, though it's likely that he didn't care either.
• Pragmatic Villainy: He fights with the heroes merely out of his prejudice towards Orphnochs and twisted love towards Mari rather than a moral principle.
• Slasher Smile: Exhibit A◊
• Smug Snake: Firmly convinced of his own superiority over the people around him.
• The Sociopath: Possibly. Kusaka is incredibly skilled at charming others and keeping his true nature under wraps, while keeping the ones who do know of his true colors isolated. He has an attachment to Mari, but it is an obsession of sorts. He also revels at the chance to fight and kill Orphnochs. However, he does show some concern to innocent bystanders and people he trusts, such as Keitaro and former members of the Ryusei Orphanage.
• The Spock: He's a cold pragmatist.
• Tall, Dark, and Snarky: Condescending towards Takumi, though he's charismatic enough to keep his true nature eclipsed from Mari and Keitaro.
• Token Evil Teammate: He might be fighting against Smart Brain, but he is still one messed up dude.
• The Unfettered: His only two goals are to protect and be with Mari and to stop the Orphnoch and Smart Brain. He'll only consider giving one of these up if he sees them as having become mutually exclusive, such as when he has to choose between giving the belts to Smart Brain or not reviving Mari; he chooses the latter since he has no guarantee Smart Brain will keep their word. Not that he didn't feel grief in doing so.
• Yandere: He gets violently jealous of anyone close to Mari. One of his main goals is taking Takumi's place in Mari's heart, or really ANYONE'S place in Mari's heart.

Tropes exclusive to him as Kamen Rider Kaixa

STANDING BY...COMPLETE!

• Brought to You by the Letter "S": The Greek letter Χ (Chi), which is part of Kaixa's motif as seen in his chest, his Memory Mission, and his insignia.
• Cool Sidecar: SB-913V Side Basshar, as the name would suggest. In vehicle mode, the Side Basshar can travel through rough terrain safely and the side car can move on it’s own. The tires are made of Sol Rubber, similar metallic properties to the Rider Gears. In Battle Mode, it’s transforms into a walking battle mecha is it’s stronger aspect. The sidecar has a a pincered heat point capable of generating temperatures up to 2000 degrees celsius during grappling attacks, and the machine can fire eight to forty eight misiles with a range of 2400 meters.
• Finishing Move:
  • ''Gold Smash'': Kaixa jumps in the air and the Kaixa Pointer produces a pair of overlapping yellow energy drills around his foot while executing the deathblow with a double dropkicks.
  • ''Grand Impact'': Using the Kaixa Shot, the rider uses a energy powered knuckle-duster to deliver a punch.
  • ''Xeno Crash'': Kaixa shoots a constricting energy net from the gun section of the Kaixa Blaygun as the sword section is over-charged. Kaixa’s speed increase to slash the enemy with a dashing strike from the energy it discharges with the target.
• Flawed Prototype: Will instantly kill any users that cannot handle it properly, whereas the Faiz Gear will simply reject unqualified users.
• Handguns: Much like the Faiz Phone, The Kaixa Phone can function like one.
• Meaningful Name: "Kaixa" is pronounced the same way "Kaiser" (German for "emperor) would be. It suits both Kusaka's personality and the fact he's the best of the riders when it comes to utilising his abilities.
• Power Fist: Kaixa Shot.
• Reverse Grip: Wields the Kaixa Blaygun this way. Justified, as the blade is uni-directional and the gun barrel is away from the traditional sword edge.
• Swiss-Army Weapon: Kaixa Blaygun.
• Transforming Mecha: Side Basshar.

Renegade Orphnochs

Yuji Kiba

Yuji Kiba/Horse Orphnoch/Kamen Rider Kaixa/Kamen Rider Orga

Portrayed by: Masayuki Izumi (live), Makoto Ito (suit)

The unofficial leader of the Renegade Orphnochs.

Tropes that apply to him in general

• All Up to You: At the end of Paradise Lost a dying Yuji entrusts Takumi to fulfill his dream of peace between humans and Orphnochs.
• Beware the Nice Ones: To a lesser extent compared to Yuka, but he's also willing to kill if he's pushed too far despite being generally helpful to others, most notably Chie.
• Character Tics: Several, if he's wearing a Rider Gear. Outside of the series, this is to set him apart from other Riders with signature tics:
  • He puts the Rider Gear's phone onto the belt with his left hand when transforming. He only used his right hand if he transforms as Orga.
  • As Kaixa, he fights similarly when he was briefly using the Faiz Gear (Performing a flying side kick for the Gold Smash and wielding the Kaixa Blaygun like a traditional sword when doing the Xeno Clash).
• Despair Event Horizon: Yuka's death apparently at the hands of human police sends him over the edge and causes him to abandon his ideals. In Paradise Lost, this also happens when Murakami and Smart Lady trick Kiba into thinking Mari betrayed him in order to turn him against humanity so he can become Kamen Rider Orga.
• Deuteragonist: Yuji is the secondary protagonist of the series, with almost enough focus and Character Development as Takumi and even became Faiz as the main hero for a while. He's also the first main deuteragonist to not be a Secondary Rider (even though he ends up using two three counting Paradise Lost Rider gears).
• Fallen Hero: By the end, he ends up as an Anti-Villain after losing his humanity in Yuka's supposed death by the police and becoming the Chairman of Smart Brain.
• Henshin Hero: Has briefly had time as both Faiz and Kaixa. Notably, he's the only non-protagonist in the history of the franchise, who has taken on the role of the protagonist Rider for more than two episodes (Yuji was Kamen Rider Faiz for four episodes). Then there's him becoming Orga in the movie.
• Kick The Son Of A Bitch: In his villainous stint, he ended up killing Kusaka who've murdered innocent people, played friends like chess, and were overall horrible people.
• Let's You and Him Fight: Kusaka sabotages his attempts to become friends with Takumi. In addition to how he can be more confused about whether he's more human or Orphnoch, whether protecting either side is just, or whether either side is just at all, this results in Kiba developing an enmity against Faiz and frequently fighting him, despite building a friendship with Takumi in their human form, and at one point, both still fight for real after knowing their identities.
• Mighty Glacier: As Orga, Kiba has the best defensive and offense output of all the five Rider gears and even Faiz Axel. He has more power than Kaixa, more physical power and produces more Photon Blood than Psyga, and has more variety in his attack capabilities than Delta. It can also tank attacks from the Elasmotherium Orphnoch, the biggest and most dangerous, who killed Yuka, ate Kaidou, and smashed the Auto Vajin in one hit. The downside is that it is extremely slow, being unable to keep up with any of Faiz's forms, it's much slower than Kaixa and it's powerful armor is more weighted than the rest.
• Nice Guy: Yuji is a nice character that wants to protect humans and help Takumi in spite of his horrendous backstory. The only problem is that Kusaka has a nasty habit of tricking Yuji in fighting Faiz.
• Our Centaurs Are Different: Yes, he's the Horse Orphnoch, but his powered-up form does resemble a centaur more than anything else.
• Pre-Final Boss: Right before Takumi goes to stop the Orphnoch King, he has a one-on-one duel with Kiba. They start off doing battle as Faiz and Kaixa, before switching to their Orphnoch forms once they knock each other out of their Rider transformations.
• Redemption Equals Death: After performing a Face–Heel Turn, Kiba comes back around and sacrifices himself in the Final Battle so Faiz can defeat the Arch Orphonoch. For bonus points, his Orphnoch form reverted back into its original state, likely as a symbol of sorts
• Trauma Conga Line: Holy. The first episode alone, has him being getting into a car accident putting him in a coma for 2 years. Then dying and reviving as an Orphnoch. He then finds, one his parents are dead, two he's homeless as his uncle sold his house, and that his uncle is corrupt. Three his girlfriend moved on and is dating his cousin, and his cousin tells him this in the most jackass way possible. Then he finds out his girlfriend was a Bitch in Sheep's Clothing the whole time, namely without knowing Yuji killed his cousin she sells him out to the police right in front of him just to save herself.
• Villains Never Lie: After he does his Face–Heel Turn, he's completely honest about only wanting a future for Orphnoch kind and not caring about humanity anymore.
• Well-Intentioned Extremist: Once he's convinced that peace between humans and Orphnochs is inevitable, he begins working to ensure the Orphnochs' future at the expense of humanity.

Yuka Osada

Yuka Osada/Crane Orphnoch

Portrayed by: Yoshika Kato (live), Takeshi Mizutani (suit)

A bullied schoolgirl who became an Orphnoch. She's a nice, shy girl even if she has... issues.

---

• Beware the Nice Ones: She's the nicest and most softspoken of the Renegade Orphnochs, but push her too far and you'll find she's also the most willing to kill.
• Break the Cutie: The reason for her eventually snapping and killing her sister and basketball teammates.
• Broken Bird: Obviously, what with being the Crane Orphnoch and all.
• Jerkass Ball: In #41, she acted uncharacteristically rude against Keitaro while they're at the amusement park, pushing him to the ground simply because he tried reaching for her hand.
• Joshikousei: She was a high school student before turning into a Orphnoch.
• Loophole Abuse: This is the reason why she isn’t targeted by Smart Brain. Though she's part of the Renegade Orphnoch, she kills humans who are abusive or cruel. Because she is technically attacking humans, she is sometimes spared from the wrath of Smart Brain.
• Morality Chain: Proves to be one for Kiba, who goes off the deep end when she's killed, seemingly at the hands of humans.
• Pay Evil unto Evil: That's the thing with her: everyone she kills tends to be a gigantic jerk.
• Show Some Leg: Stops Teruo beating up Keitaro by lifting her skirt.
• The Scapegoat: Her sister blamed her for pushing her down the hill and giving her a broken ankle when it wasn't her.
• Star-Crossed Lovers: With Keitaro. Even when they finally do hook up she gets killed not longer after, having just enough time to leave him a farewell message before passing on.
• Token Good Teammate: She's far and away the nicest of the Orphnochs along with Kiba and among the Renegades, though she had a good amount of bodycounts consisting of Asshole Victims, she's the only one who never turns outright evil.
• The Unfavorite: Her parents prefer her sister over her.

Naoya Kaido

Naoya Kaido/Snake Orphnoch

Portrayed by: Mitsuru Karahashi (live), Hideki Hatsu (suit)

An eccentric former musician who also becomes an Orphnoch.

---

• Cloudcuckoolander: He's eccentric to the point of insanity.
• Death by Adaptation: In the Paradise Lost movie he gets eaten by the Elasmotherium Orphnoch.
• Death Seeker: Inverted in Kamen Rider Yongou where after having spent 10 years without his dead friends, he decides that death is completely meaningless and full of sadness, and is willing to protect Takumi's life at any cost... even if that's the whole world being under the reign of Shocker.
• Game-Breaking Injury: Had to abandon his ambitions to become a professional guitarist due to an injury to his hand.
• Hair-Trigger Temper: In addition to being eccentric he often has mood swings that cause him to get angry.
• Jerk with a Heart of Gold: Acts aloof towards Kiba and Yuka but he does genuinely care for them.
• Oblivious to Love: Remains cheerfully unaware that Yuka has feelings for him.
• Sole Survivor: He is the last good Orphnoch alive of his own series following the conclusion of Kamen Rider Yongou. Kaido, however, wonders if Takumi is still walking on the face of Earth.
• Wild Card: Kaido goes back and forth on whether he wants to help humanity.
