    Aruto Hiden/Kamen Rider Zero-One 

Aruto Hiden/Kamen Rider Zero-One/Kamen Rider 001

Portrayed by Fumiya Takahashi (live), Yuya Nawata (suit)

https://static.tvtropes.org/pmwiki/pub/images/aruto_hiden.png
There's only one strongest company president in the world, and that's me!
The protagonist of Zero-One, as well as the titular Rider.

Aruto dreams of being a professional comedian, but doesn't have the talent for it. After his grandfather's passing, he's named the President of Hiden Intelligence and receives the authority to transform into Kamen Rider Zero-One.
  • 100% Adoration Rating: In Episode 16, the higher-ups of Hiden convene to determine whether or not to remove Aruto as President. When they vote for Aruto's removal, no one other than Jun raises his hand.
  • Adorkable: He is a Kamen Rider, but he also aspires to become a comedian. Sadly, no one laughs at his quips. Even in the world of business, he's not afraid of cracking some jokes and goofing around. The first thing he does in his grandfather's room is to fiddle around with all of the decorations and machinery in there out of excitement. He also playfully calling his Progrise Keys with some kind of Affectionate Nickname (for example, he refers Flaming Tiger Key as "kitty").
  • All-Loving Hero: Whether human or HumaGear, Aruto cares about everyone and only wishes for everyone to be happy.
  • Androids Are People, Too: He is a fervent believer of this, due to being raised and saved by his HumaGear father, and thus works to save both humans and HumaGears alike.
  • Authority Equals Asskicking: Only the CEO of Hiden Intelligence can don the Zero-One suit, and Aruto does more than his fair share of beating down opponents from day one.
  • Badass in a Nice Suit: After he's named the new CEO of Hiden Intelligence, he starts wearing a suit... over his hoodie, showing his lack of professionalism. When he does do something actually worthy of his CEO title, however, he wears the full thing and looks a lot sharper. He's also a Kamen Rider, so naturally he qualifies for the badass part.
  • Berserk Button: Don't mock anyone's dream. And Horobi's actions are enough to make Aruto angry, such as causing Shinya Owada to get injured, which made Aruto tell Horobi that what he did was unforgivable.
  • Big Name Fan: Is a huge fan of the In-Universe Perfuman Sword manga and was practically squeeing when he got to meet the manga's artist even as President of Hiden Intelligence.
  • Butt-Monkey: He is late to his job, finds out an android is a better comedian than he is and trips performing a dramatic slide after the finisher.
  • Catchphrase:
  • The Chains of Commanding: He is responsible for the company and whatever happens with the HumaGear is automatically blamed on him. The pressure probably starts growing exponentially after MetsubouJinrai.NET's attack on the hospital in #9 and #10.
  • Cheer Them Up with Laughter: Following an incident in his childhood where he failed to get a "smile from the heart" from his HumaGear father shortly before the latter's demise, with his last words telling Aruto to follow his dreams, he grows up to be an aspiring comedian to bring smiles to people around him. He soon learns there are other ways to bring joy to people, such as being a hero.
  • Color-Coded Secret Identity: Thankfully it's not too outrageous, as the prominence of the colors is switched around (Zero-One is black with neon yellow armor and some red highlights; Aruto meanwhile wears his suit with a bright red hoodie and neon shoes).
  • Contrasting Sequel Protagonist: Aside from being the first of the new era to contrast with the last of the previous era, Aruto's goals and character are far more mundane than Sougo Tokiwa's. While Sougo was a seemingly normal high school student who was destined to become the ruler of time, Aruto is an adult CEO whose dream is to become a comedian. Sougo's dream is absurd, but well within his abilities, while Aruto's dream is modest, but impossible due to his utter lack of comedic talent.
  • Determinator: As many a rider, he has a resolute streak that drives him forward through the good and bad. In the first episode he charges at the Berotha Magia unarmed to save people and getting knocked around doesn't stop him.
  • Don't Explain the Joke: Says this word-for-word when Izu takes apart his joke in order for people to understand it.
  • Early-Bird Cameo: He makes a brief appearance in Kamen Rider Zi-O: Over Quartzer, as part of a dream that Sougo wakes up from at the beginning of the movie.
  • Ensign Newbie: Due to having only inherited his position as President through nepotism, Aruto is completely new to corporate work and the A.I. industry, generally lacking work ethics and the intellect to create/fix robots his grandfather was widely known for, and he barely scrapes by his days at work by just being a Honest Corporate Executive.
  • Foil: To Corrupt Corporate Executives like Gai. Gai is also a Kamen Rider and CEO, while engaging in several underhanded schemes to get his company ahead. Aruto, on the other hand, is a Honest Corporate Executive who uses his position to help HumaGear and humans co-exist while fighting to defend both as Zero-One, even going so far as to reveal his identity to Isamu, in spite of Izu telling him otherwise.
  • For Happiness: Aruto wanted to become a comedian because he enjoys the laughter and smiles from everyone.
  • Giftedly Bad: He really wants to be a great stand-up comedian, but his entire style of comedy consists of very lame puns and ridiculous overacting even by Japanese comedy standards. No matter how much he tries, he only ever gets awkward silence from his audience (if they haven't left the room already). Not that it ever stops him. So far, the only one to find his jokes funny In-Universe is Isamu.
  • Godzilla Threshold: In Kamen Rider: Reiwa The First Generation, due to the presence of Another Zero-One, Aruto can't use the Zero-One Driver to transform. As a result, he has to use another transformation belt. The belt in question? The MetsubouJinrai Force Riser.
  • Hero with Bad Publicity: Izu tells him to hide his identity from A.I.M.S... and thus they assume he's a military-grade HumaGear who either went rogue or was dispatched by Hiden to cover up the rampaging android incidents. Needless to say, their early meetings are rather unfriendly, and usually involve gunfire.
  • Hidden Depths:
    • Surprisingly enough, when he isn't trying to make a joke Aruto is shown to actually have the people skills and PR chops you'd expect from the CEO of a large corporation.
    • Also surprisingly, Aruto is very possessive when it comes to his equipment. He demands Jin give back the Flying Falcon progrise key he stole and gets mad at Fuwa when Fuwa takes the Attache Calibur, also demanding he give it back. And Aruto even attempts to use Jin's Attache Arrow to fight him when he used the Attach Calibur.
  • Honest Corporate Executive: In contrast to villains such as Kuroto Dan or Juzaburo Namba, Aruto runs on this in order to defend people from MetsubouJinrai.net, as well as to clear Hiden Intelligence's reputation and have everyone live in harmony with the HumaGears without any form of misunderstandings. He begins asserting his credentials regarding this as early as episode 2, where rather than try to cover up the Magia situation as Jun tries to do, Aruto makes the identities of the true culprits public knowledge, complete with video evidence, and then in episode 4 where he reveals that the Daybreak Incident was also caused by MetsubouJinrai.NET in order to exonerate a lab technician that was blamed for it. In the same episode, he also revealed his Zero-One identity to Isamu, making his secret identity last for only 3 episodes.
  • Incredibly Lame Pun: His comedy is heavily reliant on quick wordplay gags. Even in-universe, they're considered rather half-baked compared to those of his fellow comedians who use longer jokes or props.
  • Instant Expert: Played with. When Aruto first puts on the Zero-One Driver, it uploads his consciousness into Hiden Intelligence's satellite, where he goes through a Year Inside, Hour Outside tutorial on its usage before regaining consciousness to combat the Magia and even then, in his first use of Rising Impact, while he successfully defeated the Berotha Magia, he failed to stick the landing and crashed against the wall.
  • Large Ham: He has a remarkable range of exaggerated expressions and tends to overreact at times. It's also part of his routine as comedian.
  • The Main Characters Do Everything: Aruto's inexperience with corporate work leads him to believe being the company's president also requires him to meet every client face-to-face and personally deliver their HumaGears (and of course, he's also pulling triple duty as a Kamen Rider), which tends to perplex other company staff. Of course, this conveniently lets him keep running into new adventures every episode.
    • Of course, given that he only accepted becoming a CEO to be able to protect people as Zero-One, this works on his favor.
  • Nice Guy: Aruto's dream is to make people smile. It was why he became a comedian. This dream also means protecting smiles, like a certain other Rider who was the first of his era. And he respects HumaGears and cares for them very much. A good example is from episode 2, where Aruto has a friendly conversation with a security HumaGear named Mamoru and thanks him for protecting the employees at Hiden Intelligence. Aruto sees a wound on Mamoru's arm and it reminded him of his father, so he decides to give him a handkerchief bandage to cover up his wound. He even tells Mamoru that they are a family together after finding out his grandfather gave Mamoru his name.
  • The Nicknamer: Does this to the Progrise Keys that are/was in his possession (i.e Flying Falcon is dubbed Tori-chan/Birdy, Flaming Tiger is dubbed Tora-chan/Kitty, etc).
  • Poor Communication Kills: Notably defied, given the franchise's history with this trope. Aruto is an extremely honest person who publicly reveals the discoveries he makes about the rogue HumaGear situation and his Secret Identity lasts for all of three episodes before he decides to drop it to remain honest.
  • Pungeon Master: Aruto's act specializes in bad puns, and he brings out one or two in every episode.
  • Raised by Robots: When he was young, he was taken care of by the Soreo Hiden HumaGear.
  • Refusal of the Call: He's not interested in succeeding his grandfather until he gets involved in a HumaGear attack and asks Izu to hand him his Driver. Even after he becomes a Kamen Rider, he's still not actually sold on the position and only does so because he wants to protect people.
  • Resigned to the Call: Wasn't particularly interested in being the CEO of Hiden Intelligence, questioning if someone who lives by the punchline should even be in such a predominant position. Unfortunately, being the CEO is the only way he can fight as Zero-One and protect innocents.
  • Ripple Effect-Proof Memory: In Kamen Rider Reiwa: The First Generation, Aruto is unaffected by the timeline changes created by Finis and Another Zero-One. This is either due to him being a Singularity Point or being a creation of Sougo Tokiwa like the Future Riders.
  • Screw the Rules, I'm Doing What's Right!: Ultimately forgoes Izu's advice to hide his secret identity from A.I.M.S. in order to prove to them that he's an Honest Corporate Executive who won't hide from them any secrets.
  • Secret Identity: Aruto hides his identity from A.I.M.S. at Izu's advice...for all of three episodes, before he decides he's had it with secrets and lies. He transforms in front of Isamu as a conscious refutation of this trope, deciding he can't be an Honest Corporate Executive if he keeps secrets.
  • Tough Room: Most don't laugh at his jokes...except for Isamu.
  • Trauma Conga Line: As a child, he lost both his biological father and his surrogate robotic one within the span of a few years.
  • Unexpected Successor: He was the last person to ever think his grandfather would name him as the next CEO of Hiden Intelligence.

Warning, Warning. This is not a test.

HybridRise! Shining Assault Hopper!

No chance of surviving this shot.
https://static.tvtropes.org/pmwiki/pub/images/kr01_zero_one_metal_cluster_hopper.jpg
Progrise! Let's Rise! Le! Le! Let's rise! Metal Rise! Secret material Hiden Metal! Metal Cluster Hopper! It's high quality.

  • Ability Mixing: Shining Assault Hopper is made possible thanks to Aruto combining the Assault Grip from the Assault Wolf Progrise Key with the Shining Hopper Progrise Key, creating a form that has both Shining Hopper's incredible speed and Assault Wolf's incredible power. As an extra bonus, both Zea and the Ark work together to create the armor.
  • Absurdly Sharp Claws: Flaming Tiger form gives Zero-One the Tiger Gauntlets, a pair of claws that also have ports in the palms that can release streams of flames. Freezing Bear also has its own pair of claws called the Bear Gauntlets, which also has similar capabilities as Flaming Tiger.
  • An Ice Person: It's in the name of Freezing Bear. With his Bear Claws, Zero-One can generate and manipulate ice from the palms and tear through everything.
  • Animal Motif: Each of Zero-One's Progrise Keys is named for the ability it grants and the animal motif of the resulting form. So far these include:
  • Blade Below the Shoulder: Biting Shark form trades some of Zero-One's physical power for access to blades on all four limbs called the Shark Gauntlets and Shark Greaves. While its abilities are best suited to fighting underwater, on land it still stands out in situations where slicing attacks are a necessity.
  • Combat Parkour: Zero-One is capable of doing flips in battle thanks to Rising Hopper's jumping abilities.
  • Confusion Fu: As Shining Hopper can calculate and change tactics at the last second, predicting Zero-One's next move becomes impossible.
  • Dark Is Not Evil: Compared to the soft-angled and primarily white color-schemed Vulcan and Valkyrie, Zero-One's dark suit, harsh edges, and red eyes would look rather menacing in certain circumstances. However, Aruto remains a heroic figure all the same.
  • Deadly Upgrade: Much like Drive's Type Formula, Shining Hopper form grants Zero-One more speed and strength than his body is capable of handling, with extended usage causing him to collapse from the strain.
  • Doppelgänger Spin: The Shining Hopper and Shining Assault Hopper forms can create holographic digital images of Zero-One that can be used to distract the opponent and he can pick one of the images in motion to use for his next move.
  • Drone Deployer: Shining Assault Hopper has a "Shine System" that deploys the Shine Cryster which acts both as an Attack Drone and an Orbiting Particle Shield.
  • Finishing Move: Depending whether from his Driver or an auxiliary weapon.
    • Zero-One Driver
      • Rising Impact: In Rising Hopper form, Zero-One runs up the the enemy and launches it up in the air via a kick before performing two powerful rider kicks: one to thrust the enemy back downward, and the other to destroy it.
      • Biting Impact: In Biting Shark form, Zero-One repeatedly slashes the enemy with the shark fins on his arms and legs, projecting chartreuse yellow and teal crescents in the process, before sending them sky high, projecting several teal energy shark fins from his arms, and slashing the enemy with them.
      • Flaming Impact: In Flaming Tiger form, Zero-One projects a ring of fire before charging through them and delivering powerful slashes at the enemy with the Tiger Gauntlets.
      • Freezing Impact: In Freezing Bear form, Zero-One freezes the enemy into a glacier before chopping him/her in two.
      • Breaking Impact: In Breaking Mammoth form, Zero-One detaches one of the Progrise Keys mounted on its arms before kicking it down towards the enemy and crushing them with it.
      • Shining Impact: In Shining Hopper form, Zero-One delivers a pair of high-speed kicks. A more powerful version is called the Shining Mega Impact, which allows him to delivers a series of high-speed kicks that propel the enemy into the air before landing more kicks, destroying the enemy.
      • Shining Storm Impact: In Shining Assault Hopper, Zero-One jumps and performs a Rider Kick charged with yellow and blue energy at high speeds.
    • Attache Calibur
      • Rising Kaban (Dispatch/Encased, depending on the fansub) Slash: By inserting the Rising Hopper Progrise Key in his Attache Calibur in Blade Mode, yellow cyber-like energy is emitted from the Attache Calibur's blade before Zero-One delivers a powerful slash.
      • Biting Kaban Slash: By inserting the Biting Shark Progrise Key into it while it's in Blade Mode, teal cyber-like energy is emitted and makes projections of multiple shark fins before Zero-One delivers a powerful slash.
      • Flaming Kaban Dynamic: By inserting the Flaming Tiger Progrise Key into it while in Blade mode then charge it in Attache Mode then switch back to Blade Mode, Zero-One delivers a series of red fiery slashes.
    • Authorise Buster
      • Buster Bomber (Rising Hopper): By inserting the Rising Hopper Progrise Key into the Authorise Buster in its Axe Mode, Zero-One performs a slash charged with yellow energy.
      • Progrise Dust (Rising Hopper): By scanning the Authorise Buster in its Gun Mode with the Rising Hopper Progrise Key, Zero-One can fire bullets charged with yellow energy.
      • Zero-One Dust: By scanning the Authorise Buster in its Gun Mode on his Hiden Zero-One Driver, Zero-One can fire a energized bullet that takes the shape of a grasshopper before striking the enemy.
      • Buster Dust (Freezing Bear): By inserting the Freezing Bear Progrise Key into the Authorise Buster in its Gun Mode, Zero-One shoots an energy polar bear construct.
      • Zero-One Buster Bomber (Biting Shark): By inserting the Biting Shark Progrise Key into the Authorise Buster Axe Mode, and then scanning it on the Hiden Zero-One Driver, the Authorise Buster generates two projections of several energy shark fins every time its swung, which deliver a powerful "bite" to the target.
  • Flight: Flying Falcon grants Zero-One the ability to fly and primarily focuses on aerial battle.
  • Fragile Speedster: Flying Falcon trades much of Zero-One's physical strength for the power of Flight.
  • Force and Finesse: Zero-One and 001 have this dynamic regarding of their respective armor. While Rising Hopper's Zero-One Driver has a sleek design to allow maneuverability and easier movement, Rising Hopper's Force Rise have more heavy armor-like design for seemingly the use of brute strength.
    • Shining Hopper also served as Finesse to Assault Wolf's Force. Shining Hopper emphasized on Super Speed for instant movement and Confusion Fu alongside Doppelgänger Spin to distract and creating an opening when battling the enemies.
  • Glass Cannon: Flaming Tiger trades some of Zero-One's defense for further increase in power.
  • In a Single Bound: Rising Hopper allows Zero-One to jump to enormous heights. He actually underestimates this ability in its first usage, and ends up landing on top of a roller coaster platform dozens of feet in the air just from trying to jump over his opponent's attack.
  • Informed Attribute:
    • For the first time in many years, Rising Hopper's jumping power is not this trope. Zero-One frequently displays a degree of superhuman leaping skills in regular combat that most of the Heisei Riders reserved near-exclusively for when delivering a Rider Kick. In this regard he's closer to the Showa Riders, who more commonly exhibited similar jumps, but with the benefit of modern special effects.
    • Biting Shark's official stats focus on its proficiency in deep-sea combat, but this is not what it's developed for in the show, and its debut fight takes place in water that's barely ankle-deep. Emphasis is instead placed on its multitude of bladed weapons and their utility against opponents trying to restrain Zero-One.
  • Jack-of-All-Stats: Zero-One's main strength is his versatility to change his form based on what enemy he is fighting with. He may not have the firepower and brute strength of Vulcan and the speed and quick reflexes of Valkyrie but his adaptability is more than enough to put him in equal standing with the former two.
  • Lightning Bruiser: Shining Hopper and Shining Assault Hopper give Zero-One greater strength and speed, which is only limited by how much his body can handle its power.
  • Logical Weakness: As amazing as Shining Hopper's ability to change attacks in an instant via Flash Stepping is, it won't matter if the opponent is either fast enough to react to the sudden changes and/or tough enough to endure the attacks outright. Thouser is capable of both.
  • Mid-Season Upgrade: In episode 12 of the tv series, Zero-One gains the new Shining Hopper Form, and shown in action during episode 13 where the new form gives Aruto a power boost to go toe-to-toe with the Dodo Magia. This form will also be appearing in the winter movie. Shining Hopper can also upgrade into Shining Assault Hopper, although this upgrade is only available whenever Aruto can get his hands on the Assault Grip. However eventually Zea prints another for him, not only enabling use whenever needed, but allowing Vulcan to keep his.
  • Mighty Glacier : Being a Mini-Mecha, Breaking Mammoth is easily the strongest form Zero-One ever had but since it was meant to protect people from harm, it is also the slowest among them.
    • Freezing Bear is also this but not as much as Breaking Mammoth. Having an extra armor and increased strength to subdue the enemy.
  • Mini-Mecha: Essentially what Breaking Mammoth is. It's a mecha that Zero-One can use when combating against giant opponents like the Gigers.
  • Mythology Gag:
    • Zero-One has a similar name and theme to the very first Kamen Rider, as the original was named "Ichigou" ("#1") and also patterned after a grasshopper.
    • His simplistic design also shares similarities to the design of Kamen Rider Kuuga, the first Kamen Rider of the Heisei Era.
  • New Powers as the Plot Demands: The Hiden Intelligence satellite is capable of fabricating entirely new Progrise Keys to help counter enemy tactics. Episode 3 implies, however, that the Keys are actually being recreated rather than invented, and that Korenosuke took them from Daybreak Town during or after the event that destroyed the city.
  • Playing with Fire: It's in the name of Flaming Tiger. This form gives Zero-One flame powers and he can use the ports of his Tiger Gauntlet's palms to release streams of flames and enhance the tip of the claws to make them hotter.
  • Red Eyes, Take Warning: Rising Hopper has red eyes, and serves as the default form for Zero-One.
  • Sinister Scythe: Breaking Mammoth features two Graingots, tusk-like scythes that Zero-One can use as weapons. When not in use, they're stored on the Mammoth Breast. In his first battle using it, he demonstrates the ability to steal the identical weapons from the chest of a Giger.
  • Super Speed: When using the Rising Impact finisher in Rising Hopper form, Zero-One gains a temporary speed boost to perform the Rider Kick finisher in rapid motion. When using Shining Hopper form, Zero-One is given a permanent speed boost that he can use freely and he goes even faster when using the Shining/Shining Mega Impact finisher. Once Shining Assault Hopper is fully powered up, Zero-One's speed cranks up even further.
  • Speed Echoes: Zero-One in Shining Hopper form creates digital after-images when using his speed powers.
  • Sword Beam: By using a Full Charge in Attache Mode and then switching it to Blade Mode, Zero-One can use a Kaban Slash that unleashes a wave of energy from his sword.
  • Throwing Your Sword Always Works: Zero-One in Shining Assault Hopper form can throw his Authorise Buster.
  • Tron Lines: Zero-One's black undersuit has red lines going through it.
    • Shining Hopper's, and by extension,Shining Assault Hopper's, undersuit replaces the red lines with gold ones. Fitting for a form that uses brightness.
  • Weapon of Choice: Zero-One has the Attache Calibur, a Cool Sword that transforms from a briefcase. By inserting a Progrise Key into the slot at the bottom, he can infuse the energy from the Progrise Key into the sword to enhance its state. When using Shining Hopper or Shining Assault Hopper, Zero-One wields the Authorise Buster, a axe and blaster weapon.

Tropes exclusive to him as Kamen Rider 001

https://static.tvtropes.org/pmwiki/pub/images/kr01_zerozero_onerisinghopper.png
Force Rise!
Rising Hopper!

A jump to the sky turns to a Rider Kick. Break Down.
  • Clipped-Wing Angel: Like Kamen Rider Joker or Drive Type Super Dead Heat, 001 is a kitbashed emergency form that's used only because Zero-One's regular powerset isn't available. The transformation itself is visibly agonizing, and 001 lacks Zero-One's array of tools and more powerful forms.
  • Dark Is Not Evil: Although it's a Force Riser-based form and shares Horobi and Jin's aesthetics, Aruto is still heroic nonetheless.
  • Force and Finesse: Played With. Zero-One and 001 have this dynamic regarding of their respective armor. While Rising Hopper's Force Rise have more heavy armor-like design for seemingly the use of brute strength, Rising Hopper's Zero-One Driver has a sleek design to allow maneuverability and easier movement,
  • Loophole Abuse: Another Zero-One's alteration of history prevents Aruto from transforming using his real Driver, but the Force Riser that existed before the point when history was altered isn't affected. Plus, it allows him to become what basically and technically is a different Rider. As in, he just lost his Zero-One power, but nothing stops him from becoming 001 instead.
  • Painful Transformation: Aruto screams and contorts in agony when he changes into this form.

    Jun Fukuzoe 

Jun Fukuzoe

Portrayed by Kazuya Kojima

https://static.tvtropes.org/pmwiki/pub/images/jun_fukuzoe.png
As the Vice-President of Hiden Intelligence, Fukuzoe was expected to take the President's chair after his passing, only to be passed over for Aruto. Now bitter and resentful, he schemes to have Aruto ousted from the company.
  • Always Second Best: Despite having been the Vice-President of Hiden Intelligence for quite a while, and being an excellent staff member, Fukuzoe has a Inferiority Superiority Complex due to being passed over. This is made apparent when he learns that Aruto, Korenosuke's grandson, is named the new CEO of Hiden Intelligence instead of him. He is not happy about this whatsoever and largely believes Aruto got it through nepotism.
  • Evil Laugh: More "scheming" than evil, but he's prone to laughing to himself while plotting Aruto's removal from the company.
  • Green-Eyed Monster: He believed that he was going to be the new President of Hiden Intelligence, but he's been passed over in favor of Aruto, the President's grandson. He openly hopes Aruto fails so he can replace him. In #2, he flat-out tells Aruto to step down. His jealousy has gotten to the point where he is plotting to oust Aruto from the company with his own group of subordinates.
  • Heads I Win, Tails You Lose: While he greatly covets the presidential chair, he recognises that as the company's Vice-President, he still benefits if Aruto does a good job keeping Hiden Intelligence in the black.
  • Heel Realization: Although he still wants Aruto's position, he is convinced by Sanzo that Aruto remain as president because he saved their company as Zero-One.
  • Hidden Depths:
    • His complex and hostility towards Aruto aside, he is a longtime and competent worker at Hiden Intelligence, and is genuinely proud of the success of the company. It just doesn't show well, filtered through his gigantic ego.
    • He is implied to have deeper knowledge behind the Daybreak Incident due to being a longtime worker of Hiden Intelligence, however he refuses to say anything about it in order to protect the company.
  • It's All About Me: When he thought he was going to be the new president he wasted no time at all replacing Korenosuke's framed painting with an even bigger framed painting of himself the day of Korenosuke's funeral. Similarly, when Aruto crashes his press conference trying to cover the Magia incident up with evidence of MetsubouJinrai.NET's existence and involvement in the berserk HumaGear attacks he looks like he's going to clench his teeth hard enough to break them at Aruto showing him up and proving to be a better public speaker than him when he's not cracking jokes.
  • Jerkass Has a Point:
    • Is completely correct (for now) when he says Aruto only got the position of CEO through Nepotism.
    • When questioned about the Daybreak Town Incident, he claims he doesn't recall anything. When Aruto calls him out believing he has something to hide, all Jun says is that protecting the company sometimes means one must keep the truth in the shadows.
    • Calls out Aruto for his biased opinion towards Choichiro Ishizumi after the former claims that lazy people like Ishizumi should not be using HumaGears as slaves, nor as money-making tools.
    • Say what you will about his demeanor, but Jun isn't wrong when he attempts to have the HumaGear in the hospital shut down before they can become Magia. Granted, he'd be leaving a lot of patients including Fuwa in critical condition, if not leaving them to die, but it's better than having to deal with even more casualties.
  • Jerk with a Heart of Gold: Played with. While still trying to gun for Aruto's seat as President of Hiden Intelligence, he admits, albeit reluctantly, that he knows to give the young President credit for his actions as Zero-One where credit is due.
  • Kick Them While They Are Down: After Izu is damaged in battle in Episode 15, Jun tells Aruto that had he been promoted to President instead of Aruto, none of the show's events would have happened. Afterwards, he goes off to schedule a board meeting to request Aruto's removal as President.
  • Obstructive Bureaucrat: He seems less worried about letting HumaGears live up to their original purpose of improving people's lives like Korenosuke and Aruto and more concerned with keeping Magia attacks covered up so they don't affect Hiden Intelligence's bottom line.
  • Wrong Genre Savvy: He seems to think he's in a business drama and not a tokusatsu series. Despite having knowledge of Zero-One, not even once he ever thought or mentioned the possibility that he has to also fight as Zero-One if he took the CEO role from Aruto.

    Sanzo Yamashita 

Sanzo Yamashita

Portrayed by Arata Saeki

https://static.tvtropes.org/pmwiki/pub/images/sanzo_yamashita_0.jpg
A member of Hiden Intelligence's Board of Directors and Jun Fukuzoe's sycophantic subordinate, always enabling his schemes without question.
  • Evil Laugh: Like Jun, more "scheming" than evil. He usually joins in on the Vice-President's because he's a suck up.
  • Heel Realization: He actually congratulates Aruto for helping save the company against the villains and even gives him a round of applause.
  • Satellite Character: Where Jun goes, he follows. Episode 5 is the first time we see him by himself.
  • Yes-Man: Jun's. He's constantly sucking up to the Vice-President's schemes. Subverted satisfyingly when not even he votes yes in Jun's attempt to oust Aruto as President.

    Korenosuke Hiden 

Korenosuke Hiden

Portrayed by Tokuma Nishioka

https://static.tvtropes.org/pmwiki/pub/images/hiden_korenosuke.jpg
Let's make a giant leap towards our dreams.
Aruto's late grandfather and the founder of Hiden Intelligence, who designed the HumaGears to advance mankind into a new era of prosperity.
  • Crazy-Prepared: According to his will, he knew the Robot War was about to happen soon, so the company satellite was already programmed to create the Zero-One Driver and give Izu her orders. This implies he deliberately chose Aruto as the person to become Zero-One and not just the heir to the company.
    • As evidenced by Zea's own Crazy-Prepared entry below, he prepared many other tools within the satellite well before it began printing the Zero-One Driver.
    • He also planned Wazu's hibernation, specifically so that Wazu would be available to assist Aruto and Izu when the time came.
  • Greater-Scope Paragon: He believed that androids are not meant to steal human jobs or shoulder all human labor, but are meant to aid humans as equal partners in the pursuit of their passions.
  • Honest Corporate Executive: From what little we've seen, he seems to be someone genuinely committed to advancing humanity's progress by advocating partnerships with HumaGears.
  • Plot-Triggering Death:
    • Korenosuke died only recently as the company receives a notification about his passing, but his will naming his grandson Aruto as the new CEO of Hiden Intelligence is what starts Aruto's journey.
    • News of his death also became the driving factor for Horobi to initiate MetsubouJinrai.NET's Project Magia, the very event Korenosuke feared would happen.
  • Posthumous Character: Korenosuke is stated to have passed away shortly before the series begins.

    Other Personnel 

Satoshi Sakurai

Portrayed by Hideto Suzuki

https://static.tvtropes.org/pmwiki/pub/images/50574.jpg
As the head of this factory, I'll make sure all HumaGears here are eliminated!
The late chief of production at Hiden Intelligence's HumaGear Factory 1. He was blamed for the town's destruction, but his son Gou, bullied for his father's supposed role in the incident, looks for the truth.
  • Heroic Sacrifice: As revealed in the lost surveillance footage, he had Factory 1 self-destruct to destroy the rampaging HumaGears within, even if he had to go with them.
  • Posthumous Character: Died during the Daybreak Town Incident 12 years before the story.
  • Vindicated by History: In-universe, after video footage of his sacrifice was found and made public, he is now regarded as a hero for what he really did.

    Satellite Zea 
A space satellite created by Hiden Intelligence, which monitors and manages all Hiden Intelligence technology on Earth, including HumaGears and Zero-One.
  • Crazy-Prepared: As part of Korenosuke's preparedness, not only is it able to issue commands for the reproduction of Progrise Keys and provide the corresponding armor, it also stores the Rise Hopper motorbike, as well as part of it being a functioning prototype Breaking Mammoth Powered Armor, which was long produced before ZAIA mass-manufactured the Gigers based off its design.
    • It is also shown to be able to anticipate MetsubouJinrai.NET and the Ark's actions and produce countermeasures beforehand. One such example is the Shining Hopper Progrise Key, which was already made compatible with the Assault Grip from the Assault Wolf Progrise Key that was produced by the Ark much later, only after MetsubouJinrai.NET had managed to revive it.
  • Giant Mecha: It is partially composed of the Breaking Mammoth Powered Armor, which is detached and sent down to Zero-One when he calls for it.
  • New Powers as the Plot Demands: Zea assists Zero-One by analysing combat data from footage sent from Izu, calculating and sending orders to manufacture the appropriate Progrise Key to counter the Magia, while also providing the appropriate armor when Zero-One uses the corresponding Progrise Key.
  • Secret Weapon: It is only known to the public as a satellite for controlling HumaGears. However, it also serves as a combat assistant for Zero-One, providing most of his armory and weapons.
  • Super Prototype: Its Breaking Mammoth Powered Armor serves as one to the mass-produced Evil Knockoff Giant Mecha Giger produced by ZAIA Enterprise, which was ripped off from its design.

HumaGears

"Take off, toward a dream."
—A HumaGear's start-up announcement.
Human-looking androids outfitted with an advanced A.I. that allows them to recognize people and objects, created by Hiden Intelligence to serve and grow alongside humanity. They are the main source of conflict for the series.
    In General 
  • Alien Blood: Their physical components consist of a blue "blood" running through them, and are shown to "bleed" it when they get damaged.
  • Body Backup Drive: Combining this trope with Replacement Goldfish, any destroyed HumaGear can be rebuilt or replaced as long as its AI has been backed up or retrieved.
  • Deceptively Human Robots: They are made as human-like as possible in order to blend in to assist and support humanity. The only thing that distinguishes them from real humans are their headpiece and eyes, which light up in blue when they are active.
  • Grew Beyond Their Programming: Due to their self-learning nature, HumaGears are prone to developing more emotional traits or self-aware thinking that goes beyond human comprehension, this status being known as reaching a "Singularity". These traits can range from having pride, a drive to perform their job to their fullest ability, to even standing up against what they feel is not right. However, this also makes them targets for MetsubouJinrai.net, who seeks to collect their evolved data while overwriting their personalities.
  • Instant Expert: Played with. While HumaGears are manufactured with a basic programming specified for the field of work they are assigned to, more complex tasks such as following a specific cooking technique or art style would require them to physically learn from their human masters over time.
  • Limited Wardrobe: Many HumaGears seem to wear uniforms and costumes all the time, according to their programmed profession, like Izu. There are exceptions who wear casual clothing like Choichiro's assistants and the filming staff, and Seine was at least shown with another set of dress on her audition.
  • Noisy Robots: HumaGears tend to let out a wide variety of bleeps and so on when downloading, analysing, communicating, even blinking.
  • Replacement Goldfish:
    • Hiden Intelligence has a policy to provide one for any decommissioned HumaGear within 24 hours, however any additional skills which the original learnt that is incapable of being digitally programmed must be physically re-taught to its replacement.
    • Due to the in-universe Specialized A.I. Laws, HumaGears are not allowed, unless given special permission, to be physically modeled as one for any actual humans, be it living or dead.
  • Ridiculously Human Robots: Like the humans they're modeled after in general, HumaGears are also able to feel and express pain and suffering. This is commonly shown from their anguished screaming out of being forcibly transformed into a Magia.
  • Shout-Out: Human-assisting androids who look human except for their ears? Are they HumaGears or Persocoms?
  • Theme Naming: Most HumaGears are named based on their job, with wordplay added to make their names sound human. This extends to having punny names, or a combination of an ordinary-sounding surname with a rather "uncommon" given name based on a major item or a famous person in their industry.

    Izu 

Izu

Portrayed by Noa Tsurushima

https://static.tvtropes.org/pmwiki/pub/images/izu_the_human_gear_ai.png
A Secretary-Type AI assistant HumaGear designed to serve the President of Hiden Intelligence.
  • Borrowed Catchphrase: When she's not explaining Aruto's jokes, she also seems to be stealing his catchphrase. Might be because, as a HumaGear, she learns from those around her, and she's mostly around Aruto.
  • The Call Knows Where You Live: She tracked down Aruto, who had been recently fired at his job, and informs him that he is the new President of Hiden Intelligence, following the passing of his grandfather.
  • Don't Explain the Joke: Due to how bad Aruto's jokes are, she usually has to be the one to explain the meaning behind them, much to his annoyance.
  • Emotionless Girl: She begins the series with generally pleasant mannerisms, but has no emotional responses to any events around her, showing her basic politeness to be surface-level only. This changes over time, as shown in the Grew Beyond Their Programming example below. After achieving Singularity, she begins to display positive and negative emotions of all kinds, from happiness to annoyance.
  • Grew Beyond Their Programming: Izu gradually reaches Singularity over the course of the first fifteen episodes, at first in minor ways like exploiting Loophole Abuse against an exploitative customer, making rapid deductions and investigating suspicious activity on her own initiative, and pondering the nature of Singularity when asked her opinion about it. She reaches Singularity when she comes to understand and express the concept of family thanks to Aruto as well as Wazu's sacrifice for her sake. Unfortunately, her newfound emotions lead her to commit the very human mistake of (unintentionally) appearing to gloat over Horobi's dying body, enraging Jin to the point where he stabs her in revenge.
  • Heroic Suicide: She attempts to do this by giving Aruto's Shining Hopper Progrise Key all the battle data she's collected for Zero-One, boosting its strength for him to defeat the Dodo Magia in exchange for permanently shutting herself down. However, Wazu forcibly takes her place.
  • Incredibly Lame Pun: She begins to start using these after reaching Singularity, mostly as a result of Aruto's influence.
  • Idiot Ball: Grabs it pretty solidly in episode 15, when she approaches a visibly hysterical, still-transformed Jin after Horobi is grievously wounded protecting him and cheerfully announces, with a pleased smile, that Horobi has been defeated. Unsurprisingly, this results in the grieving and enraged Jin lashing out and attacking her, leaving her badly wounded.
  • No Plans, No Prototype, No Backup: Because of the data she has about the Zero-One Project, there are no backups of Izu's central memory, unlike many other HumaGears—and there never will be, in order to avoid a potential security leak. If she's ever irreversibly hacked or completely destroyed, there's no bringing her back.
  • Robot Buddy: She is designed to be the secretary of the Hiden Intelligence CEO, thus serving as Aruto's companion once he is named Korenosuke's successor.
  • Robot Girl: She's a HumaGear modeled to have a female appearance.
  • Super Powered Robot Meter Maid: Albeit in a downplayed manner that is logical within the story. Izu is a secretary robot to a superhero, and while she remains a non-combatant she still tosses Aruto his briefcase sword or Progrise Keys from the sidelines. Episode 3 confirms she's strong enough to evacuate a grown man on piggyback, at a brisk run - without the added weight she can reach the speed of a motorcycle!
  • Tragic Keepsake: She's carrying Wazu's watch with her after his death.
  • You Gotta Have Blue Hair: She has green streaks on her hair.

    Spaceman Subaru 

Spaceman Subaru

Portrayed by: Kyosei Kuwahata

https://static.tvtropes.org/pmwiki/pub/images/subaru_profile.jpg
Raiden's brother.
One of the two HumaGears that helps maintain and administrate Satellite Zea and the equipment Zea stores for Zero-One, the other being his older "brother" Spaceman Raiden.
  • Blue Oni: To Raiden's Red Oni. Since he's a newer HumaGear model and hasn't yet developed a distinct personality, he's much calmer and less emotive than Raiden.
  • Grew Beyond Their Programming: In Episode 15, after Izu and Aruto both try to help him understand what a family is and why it's important, he briefly expresses genuine grief over Raiden's death. The blue eye flash he has during this moment implies that he's reached Singularity, much like Izu.
  • Robot Buddy: Takes this role in a reduced capacity from Izu for Episode 15, during which she's unavailable.
  • Superior Successor: Raiden thinks of Subaru as one to himself, stating that he's positive Subaru will be able to do far more than Raiden ever could in terms of maintaining Zea once his training is complete.

    Soreo Hiden/Kamen Rider Ichi-Gata 

Soreo Hiden/Kamen Rider Ichi-Gata

Portrayed by Koji Yamamoto

https://static.tvtropes.org/pmwiki/pub/images/soreo_hideo_profile.png
Aruto's adoptive android father.
A prototype HumaGear made to replicate Aruto's father. He sacrificed himself to protect Aruto when he was younger. In Kamen Rider Reiwa The First Generation, he becomes Kamen Rider Ichi-Gata in the altered timeline.
  • Artificial Family Member: The HumaGear helped raise Aruto when he was a kid.
  • Face–Heel Turn: In the altered timeline created by Another Zero-One, he's Kamen Rider Ichi-Gata, essentially an evil version of Zero-One who battles humans to protect HumaGears while Another Zero-One declares war against the human race. In truth, he's secretly protects humanity, including his son, such as such as secretly giving him a MetsubouJinrai Force Riser as a temporary transformation device until he regains his powers as Zero-One.
  • Heroic Sacrifice: Died protecting young Aruto from an explosion.
  • No Sense of Humor: Being unable to make the HumaGear laugh or smile is part of what makes Aruto want to make others smile.
  • Plot-Triggering Death: Due to Aruto being unable to bring out a "smile from the heart" from the HumaGear version of him shortly before his destruction, with his last words telling Aruto to follow his dreams, Aruto grows up aspiring to bring smiles to people around him. This is what also spurned him to become a comedian.
  • Posthumous Character: The original Soreo died before the series began, and Aruto was raised by a Replacement Goldfish HumaGear made in his image. The HumaGear then also died after protecting Aruto from an explosion in his childhood, making Soreo this trope twice.
  • Replacement Goldfish: The HumaGear was created to replace the original Soreo after he died.
  • Super Prototype: Downplayed. He doesn't have technical superiority over production model HumaGears, especially given his much more primitive design. What he did have was seemingly fully realized sentience. His CycloneRiser is actually this to the Zero-One Driver.

Tropes exclusive to him as Kamen Rider Ichi-Gata

https://static.tvtropes.org/pmwiki/pub/images/kr01_ichigatarockinghopper.png
Cyclone Rise!
Rocking Hopper!

Type-1.
  • Evil Counterpart: To Kamen Rider Zero-One and Kamen Rider 001. Whereas Kamen Rider Zero-One is fighting to defend humanity and help them co-exist with HumaGears, Ichi-Gata is fighting with the explicit purpose of HumaGears dominating the human race. He also uses the CycloneRiser, a variation of the MetsubouJinrai Force Riser that Aruto has to use during their battle, and uses the Rocking Hopper Zetsumerise Key to transform, contrasting with Aruto's Rising Hopper Progrise Key. This gets taken another step further in regards for their respective wishes: Zero-One wants to make humans and HumaGear smile, while Ichi-Gata wants to create a world where HumaGear can smile, making no mention of humans when stating this.
  • Mythology Gag: His overall design is made to Homage the original Kamen Rider, Takeshi Hongo, in just about every way.
    • His name is "Ichi-Gata" (literally Type-1), contrasting with Hongo's "#1" (ichi-gou).
    • His suit has teal armor on a black bodysuit and his helmet has pink eyes, imitating the color scheme of Rider #1's original appearance (officially dubbed "Old #1") as well as "Hopper #1" from the reboot film Kamen Rider The First. As an added touch, Type-1 has an extended collar with red accents, referencing Rider #1's iconic red scarf, and the energy effects surrounding some of his attacks give him the appearance of a full red scarf of his own.
    • His transformation belt is the CycloneRiser, a silver and red repaint of the MetsubouJinrai Force Riser; this serves as a combined reference to Rider #1's own belt (named Typhoon, painted silver and red) and his motorcycle (named Cyclone).
    • The only thing that doesn't reference Hongo is his finishers, Rocking The End and Rocking Spark. Instead these are homage to Kikaider's finishers.

    Shester 

Shester

Portrayed by Asumi Narita

https://static.tvtropes.org/pmwiki/pub/images/shester.png
A Secretary-Type AI assistant HumaGear assigned to Jun Fukuzoe as his personal assistant.
  • Robot Girl: Just like Izu, she's a HumaGear with an adult female appearance.
  • Satellite Character: Same deal as Sanzo. Although, she does drop her cold behavior and helped announce that Aruto will remain as the president of the company, even applauding for his success.
  • Shadow Archetype: While Izu has it in her algorithm somewhere to help Aruto become a better CEO (and Kamen Rider), Shester is a textbook enabler and tool of Jun in more ways than one. Though she also has a tendency to state facts bluntly like Izu does, this is often framed in the same cold, business-focused terms as Jun's behavior tends to be.
  • The Stoic: To the point of never going beyond a Machine Monotone. She's Jun's secretary and nothing else.
  • Un-Evil Laugh: Unlike Jun and Sanzo, hers isn't even close to being an Evil Laugh. It's just her saying the word "ha" over and over again in her Machine Monotone.
