Metropolitan Police Department Special Investigation Unit

https://static.tvtropes.org/pmwiki/pub/images/specialinvestigationunit.png

The Special Investigation Unit, or SIU, was formed in the aftermath of the Global Freeze incident in order to investigate any future cases that may involve Slowdowns. Despite that, the unit is only a small team and their office isn't even located at the Police HQ, but at a driving school. Not that stops them from fighting crime and kicking butt.

General Tropes

Badass Crew: Don't let their bickering and personal issues fool you - when they get their gear on, no case shall remain unsolved for long.
Bunny-Ears Lawyer: They are rather strange, and are the last people you'd think would be able to combat the Roidmudes. Yet, once they get really serious, and with the help of a certain Kamen Rider, they can solve any case.
Creature-Hunter Organization: Seeing as all Slowdowns are related to the Roidmudes, they can be seen as such.
Decoy Protagonist: The Secret Mission Type TOKUJO mini-series is billed as an origin episode as to how each member of the SIU became a part of it, but the reasons for such are all hand waved at the end and the special is more about solving a cold case from the day of the Global Freeze and foreshadowing how deeply the Roidmudes had infiltrated the Japanese government.
Freudian Trio: The Riders, once Chase is reformed.
- The Kirk: Shinnosuke
- The McCoy: Go
- The Spock: Chase
Idiot Ball: For some reason, none of them can figure out Shinnosuke is Drive even though he carries around Shift Cars, wears the Shift Brace in public, and drives the exact same car as Drive!
- However, this could result from the lack of evidence Drive leaves, as well as the fact that no one can exactly snap a photo of Drive when a Slowdown is in progress...
No-Respect Guy: #12 has shown us that the SIU are not exactly all that well-thought of...
Oddly Small Organization: The group organized to fight the Roimudes, a group of killer robots that almost took over the world consists of only six people.
Ragtag Bunch of Misfits: The team consist of a lazy bum, an otaku, a robotic woman, wacky scientist, an Agent Scully extraordinare and a superstitious chief. The fact that their weirdness is what makes them a good unit is reminiscent of a certain high school club.
Police Are Useless: Played with. Within the rest of the police force, the Special Crime Unit is seen as a gathering of weirdos... which is not entirely untrue. But there's no denying that, when on the case, they will succeed where everyone else would be stumped.
- That's not to say that the regular police are incompetent. On a few occasions, regular police officers have tried to stand up to the Roidmudes (e.g. reborn 007 while he was searching for his human host) but are hopelessly ill-equipped for the task. And there is the small fact that one of the Roidmude bigwigs has infiltrated the government and has a lot of power over the police force and has frequently used memory alterations...
Screw This, I'm Outta Here: Played for laughs. When Jun accidentally makes himself an assassination target for the Shoot Roidmude during #34 by handcuffing himself to the android's original target, Kyu and Gen see no problem with abandoning the two as they're technically not members of the Special Crime Unit.
Time Police: Not their intended vocation, but members of the SIU find themselves contending with schemes to alter the time stream by the Roidmudes and Shocker during some of the movies and TV specials they star in.
Who You Gonna Call?: For once, the actual police!
You ALL Share My Story: The Secret Mission Type TOKUJO mini-series reveals that several members of the SIU were connected well before the unit's formation through the late Professor Odagiri.
- Lt. Otta was in charge of investigating the professor's death.
- Kyu was a student of his, and it's implied he had his work plagiarized by him.
- Odagiri was Mr. Belt's colleague way back when he was still human.
- He met several times with Prof. Banno, Kiriko and Go's father.

Shinnosuke Tomari/Kamen Rider Drive

Portrayed by: Ryoma Takeuchi (live), Seiji Takaiwa (suit)

https://static.tvtropes.org/pmwiki/pub/images/shinnosuke_tomari.png

Shinnosuke is a policeman of the Metropolitan Police Department. In his past, he was a hot-blooded elite detective, but he lost his motivation in the "Global Freeze" incident when he severely injured his partner. Shinnosuke was then "exiled" to the Special Crime Unit, traumatized by hurting his colleague and permanently removing him from the force.

Several months later he comes into the possession of the Tridoron, a car that can seemingly talk to him. He discovers that the voice is the Drive Driver, who encourages Shinnosuke to become the secret hero Kamen Rider Drive.

Tropes that apply to him in general

Accidental Misnaming: He mistakenly addresses Captain Terui as "Captain Fukui"
Accidental Murder: Not outright murder, but during the initial Global Freeze incident, he accidentally caused an explosion that would cause permanent injury to his partner.
The Ace: He was considered to be the best candidate for the role of Kamen Rider Drive by Jun and Krim because he possessed courage, intelligence, and a flexible mentality that would allow him to master the varied powers of the Shift Cars.
Babies Ever After: At some point after the series' timeline, he has a son called Eiji who appears in Surprise Future. And Eiji's dialogue about his mother implies that Shinnosuke settles down with Kiriko, which is confirmed in the series finale.
Badass Driver: The first Kamen Rider to exclusively use a car as his main vehicle.
Badass in a Nice Suit: To an extent. In all the material seen thus far, he is commonly wearing a suit. Justified, as he's a police officer and his time on the show often has him on the job.
Back from the Dead: After being killed off by 001/Freeze, Shinnosuke is revived via the Shift Tridoron Shift Car, which in turn unlocks Drive's Super Mode Type Tridoron
Berserk Button:
- Getting innocent people, especially children, involved in an evil plan is going to ensure in an early demise.
- Any clue to his father's unsolved murder makes him lose his focus, especially if it possibly connects to the Roidmudes. Unfortunately exploited by the Roidmudes on at least two occasions: he was once suspended for assaulting Brain (who had disguised himself as a special advisor to the police) and the second when he tries to confront 001.
- Albeit, he does share this with both Go and Chase, but try and involve Kiriko in whatever it is you're doing with malicious intent. Go on. We'll see how much longer you'll last.
Betty and Veronica: The Betty to Chase's Veronica for Kiriko's Archie. He won. Tragically.
Break the Badass: Was an ace policeman before the series start, but due to an accident he lost all motivation in his work.
Brilliant, but Lazy: A very good cop, but he tends to slack off during work. Once he straightens his tie though, he'll show you why he was once part of the elite.
Brought Down to Badass: He's certainly not helpless when he's out of the suit, being an elite cop and a very smart detective. Best seen in #48, when despite being unable to transform anymore, Shinnosuke declares that he's still a cop, AND a Kamen Rider.
Came Back Strong: Thanks to Shift Tridoron, he's brought back to life and has reached his true power with Type Tridoron.
Catchphrase: "I'm done thinking about it!", "My brain's in top gear now'', and "You're coming along for a ride!"
- The first one has two meanings, depending on the context. Half of the time, he says it when he just wants to slack off. The other half of the time, it means that he's going to focus all his attention on kicking Roidmude ass.
Character Tics: He'll adjust his tie, signaling that he's about to do something really badass.
- Just like Takumi and Shotaro, he'll sometimes flick his right hand while opening and closing it during battle.
Composite Character: He seems to combine Shotaro and Phillip together. He has Shotaro's half-boiled personality and gut instinct combined with Phillip's intelligence and Bat Deduction powers.
Contrasting Sequel Main Character: Kouta Kazuraba, an earnest young adult is a former member of a dance group and a Kamen Rider who fights off both an invasive Eldritch Abomination and a MegaCorp that exploits his contemporaries for their own gain, while Shinnosuke himself is a Kamen Rider who works within the police force and deals with solving crimes in regards to the Mechanical Lifeforms. Also, while Kouta was a determined individual trying to figure out how to be mature and what it meant to be an adult, Shinnosuke is an adult who starts out the series very immature due to his depression and being burntout from an incident in his past.
Cool Car: Tridoron provides him with his sweet transportation, his Handle Sword & Door Gun, and his tires for weapons and special abilities. Tridoron itself is armed with lasers, transforms with him depending on his form, and can even be enhanced with Tires of its own.
Cowboy Cop: Ironically, before the Global Freeze he was TOO passionate about his work, with Hayase having to hold him back from severely injuring criminals as seen in episode Zero. Still, it demonstrates why he was almost accepted to be part of an elite unit before the freeze.
- Shinnosuke regains bits of these traits whenever clues leading to his father's death started to pop up. Example - he nearly kills Heart when Shinnosuke tries to interrogate him for info on 001 in #26.
Deadpan Snarker: In AND out of combat. He's probably the most sarcastic Rider, and being a lazy, cynical police officer instead of a hardened hero or an innocent Wide-Eyed Idealist might have something to do with that. In combat, he's just like Spider-Man, constantly taking the chance to annoy, bicker with and insult his opponents with quips, puns and snarks.
Defective Detective: Possess a brilliant mind that can solve any case with the smallest amount of leads... but only if he isn't in one of his depression-induced lazy sessions. Later episodes later give him bouts of judgment-impairing anger when clues to his father's killer start popping up.
Dismotivation: Suffered from this hard during the interim between the Global Freeze and the events of the present. Ashamed of how he accidentally injured his old partner and believing his career to be all but over with him being transferred to the infamous Special Crime Unit, Shinnosuke spent two whole months slacking off, eating sweets, avoiding Kirkio, and ignoring how cool the Tridoron was and the fact that it seemed to be talking to him.
Don't Think, Feel: Aside from stopping himself from thinking too hard being kind of his thing, he only starts to wield the Handle Sword well after trusting his instincts instead of asking about it. Sure enough, he immediately gets a Sword with a steering wheel that MIGHT get more powerful if you turn it, and the rest is history.
The Dreaded: Because he took up the mantle of the original Drive, the Roidmudes gave him the Kamen Rider title, the masked warrior who destroys their kind.
Expy:
- Cast in the same mold as Makoto Hikawa and Ryu Terui since both of them are Kamen Riders who worked within the boundaries of law enforcement instead of being a vigilante man like most Kamen Rider protagonists.
- With Mr. Belt, he's the show's Michael Knight. Just like the protagonist of Knight Rider, he drives a super car as his main vehicle.
Excuse Me While I Multitask: Type Technic enables him to do this due to literally giving him eyes in the back of his head and advanced computer skills. He owns Roidmudes in his debut in that form while deactivating their device at the same time.
Giver of Lame Names: His naming sense consists of calling an object exactly what it is, much to Mr. Belt's displeasure.
Good Is Not Nice: Since accidentally injuring his partner Hayase during the Global Freeze incident, he has become both a slacker and too passionate about his work, nearly committing acts of police brutality on several occasions. However, under his aloof attitude and the lazy facade is a strong bearing of justice inherited from his father, along with his philosophy to protect civilians at all cost.
Great Detective: Especially whenever he goes serious to his job as a Police Detective.
The Grinch: He doesn't like Christmas all too much, due to the fact that his birthday is on Christmas Eve and as a result, gets stiffed on presents every year.
Happily Married: With Kiriko after Super Movie War Genesis.
Henshin Hero: As Kamen Rider Drive.
Heroic Sacrifice: After failing to save Go's life three times in the Kamen Rider #4 DVD, he uses himself as a way to protect him, causing Shinnosuke to die in Go's place. He also protects Yuto from Yongou's Kick in one time loop.
The Hero: Of the show.
Image Song: Spinning Wheel, which he shares with Go and Chase.
Karmic Jackpot: After Kamen Rider Drive saved and encouraged a truck driver from a monster attack, that same person later called the ambulance and saved Shinnosuke's life, not knowing he and Drive are the same person.
Knight in Sour Armor: Out of all the Phase 2 Heisei Riders, Shinnosuke is shockingly cynical compared to guys like Eiji, Gentaro, Haruto, Kouta, Takeru, Emu, and Sougo, reacting with calm acceptance when a human chooses to be evil of their own free will, which makes a lot of sense, since Shinnosuke was a cop before a Kamen Rider and his job was always to stop evil humans from the beginning. As the show goes on, however, it's shown that he can be just as idealistic as them.
Legacy Character: As displayed through flashback, there was another Drive before him. Unfortunately, Protodrive couldn't destroy Roidmude cores, and it was presumed that he died in battle. Until The Reveal.
- And of course, just like Gentaro, he's one of the few Heisei Riders who's actually called a Kamen Rider in-series.
Leitmotif: "Don't Lose Your Mind", which is about keeping yourself together no matter how hard things are or how lonely you feel. To a limited extent "SURPRISE-DRIVE" is mostly his theme as well.
Let's Get Dangerous!: Whenever he adjusts his tie, he shifts into his Great Detective persona, solves crime and kicks ass.
- Alternatively, as Drive, when his eyes start glowing, you know he'll start kicking ass.
Manchild: He acts very immaturely for a person his age, doing things like throwing tantrums and getting upset that he does not get a lot of presents for his birthday. It's even lampshaded by Kyu.
Meaningful Name: His surname Tomari derives from the Japanese word "tomaru", meaning "to stop", which has multiple layers of meaning: it represents him as a policeman (since he stops crime), the car theme of the series (as in "stop and go"), his personal state (how he tends towards laziness and apathy until something gets him fired up), and the Roidmudes' ability to stop time.
My Greatest Failure: Him accidentally injuring his old partner Hayase has made him suffer depression.
Not Quite Dead: Initially thought to be KIA'd in #32, it turned out Mr. Belt integrated his data into him, preventing decomposition, and acts as his life support.
Official Couple: Ends up with Kiriko, who he marries in Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis.
Oh, Crap!: He and Mr. Belt reacts this way when Chaser reveals in #5 he can use the Shift Cars by using poor Max Flare, who was only trying to help out.
Paper-Thin Disguise: Not for him, but for Tridoron. How does he disguise his distinctively designed personal car when he's out fighting Roidmudes as Kamen Rider? He just hides the police badge on its front.
Perennially Overshadowed Birthday: Shinnosuke is a Birthday Hater because his birthday falls on Christmas Eve, which meant he's spent his whole life getting combined Christmas-birthday parties and presents. During the birthday depicted in the series, his Fair Cop partner Kiriko invites him out to dinner; he's happy at the prospect of a date, but is much less pleased when all their co-workers jump out and shout "Happy Birthday!"...and even less so when Da Chief announces that this party will also serve as the office Christmas party.
Phlebotinum Rebel: He himself notes that he's fighting Roidmudes with tools and powers that come from the same source as them, Drive and the Shift Cars. Since Drive even has the power to cause Slowdown on normal people, the fact that he's a good person makes this all the more relevant.
Pre-Asskicking One-Liner: My name is Kamen Rider Drive! *leans in towards the Roidmude* And you're coming along for the ride.
Red Oni, Blue Oni: The balanced, professional blue (one of two) to Go's reckless and flashy red. Although Go is consistently more easygoing while Shinnosuke tends to lose his cool rather quickly.
- In Episode 0, his impulsiveness makes him the red to Hayase's blue.
- He also served as the red to Chase's stoic blue.
Running Gag: Like Haruto, he'll never finish his box of milk balls.
She Is Not My Girlfriend: After Chase asks whether or not Shinnosuke is in love with Kiriko, he denies it, coming up with a collection of excuses why the two would never be together outside of work. Ultimately, it turns out he's definitely in love with Kiriko...and he didn't realize it until Chase asked him in the first place.
Super Cop: He was already a badass elite cop before the show. And then he became a Kamen Rider...
Take Up My Sword: A self-made one. Once he hears of Proto-Drive and Kiriko's admiration of him, he decides to succeed him and take up his mantle, officially declaring himself Kamen Rider Drive before stomping 010 into dust.
Trademark Favorite Food: He'll often be seen eating milk balls when off the job, which is often early on. As the show progressed, he eats them less and less, only eating them as a sign he's stumped on something.
Tranquil Fury: How he unlocks Type Technic.
Shinnosuke: It's strange... I never thought I could get so mad that it would clear my head. Now you get to face cool justice.
Unknowingly in Love: Played for laughs when he and Chase are at the cafeteria drinking with the latter asking the former if he's in love with Kiriko. This causes Shinnosuke to drop his drink and loudly deny it but Chase believes it because he saw him spying on him and Kiriko at the rooftop. Shinnosuke still denies it and points outs her flaws such as being violent to him. When Kiriko shows up to discuss about the case, Shinnosuke gets distracted by looking at her but leaves immediately which conforms Chase's suspicion. As they leave, Shinnosuke begins to realize that he does have feelings for Kiriko after remembering the times they spent together while on duty.
Shinnosuke: Now I see it...I really do have feelings for her...I have all along...
What You Are in the Dark: When alone he's face to face with his father's killer, who is taunting him to take the shot Shinnosuke keeps his cool until his backup arrives.
Yank the Dog's Chain: He thought he got a date with Kiriko in #11. Turns out it was just his Birthday/Christmas/New Year's End party.
You Fight Like a Cow: Likes to crack wise during his fights.
You Killed My Father: Once it becomes clear that the Roidmudes were involved with the death of his father, this becomes Shinnosuke's Berserk Button, which the androids gleefully keep pressing to their advantage.

Tropes exclusive to him as Kamen Rider Drive

https://static.tvtropes.org/pmwiki/pub/images/krdr_drivespeed.png

Drive: Type Speed!

https://static.tvtropes.org/pmwiki/pub/images/krdr_drivewild.png

Drive: Type Wild! Go-go-go, o-o-on, let`s do it!

https://static.tvtropes.org/pmwiki/pub/images/krdr_drivetechnic.png

Drive: Type Technic!

https://static.tvtropes.org/pmwiki/pub/images/krdr_driveformula.png

Drive: Type Formula!

https://static.tvtropes.org/pmwiki/pub/images/krdr_drivetridoron.png

Drive: Type Tridoron!

All Asians Wear Conical Straw Hats: Not straw in this case, but Type Fruit gives Drive one that looks like an orange slice.◊
All Your Powers Combined: Type Tridoron gives him the abilities of all the Shift Cars, which are put into groups of three (each group having their own theme), such as Attack 1.2.3 combining the powers of the hotrods Max Flare, Funky Spike, Midnight Shadow.
Bare-Fisted Monk: Though Drive has access to a variety of weapons, in fights he mostly uses his punches, kicks and grapples mixed with the Shift Cars' powers. Justified, as Shinnosuke was trained as a police officer and thus has hand to hand training.
The Berserker: Type Dead Heat can cause Shinnosuke to lose control if used for too long. Unusually for the trope, however, he doesn't lose his mind when he goes berserk, but rather, his armor goes wonky.
Cool Sword: The Handle Sword. Despite Mr. Belt's disapproval of the rather sad name, he can turn the wheel to power up the sword with TURN! attacks, and after three turns he can perform U-TURN! attacks that allow him to slide across the battlefield. If he honks the horn instead, he performs the "Drift Rotation". By loading Shift Cars into the back of the hilt, he can perform Full Throttle attacks.
Deadly Upgrade:
- Type Dead Heat runs the risk of losing control and making the Drive System out-of-control, causing him to attack anyone in the area.
- Type Formula has its issues as well; Shinnosuke sprains his neck simply by using it's Full Throttle due to the massive g-force he was forced to endure. The Trailer-Hou, Mantarn F01, Jacky F02, and Sparner F03 Shift Cars are all made so that his body can last while in this form without overexerting himself.
Finishing Move: By turning Mr. Belt's Advanced Ignition, pressing the Igniter on the Shift Brace, and lifting the Shift Car currently in place once, Drive can perform "Full Throttle" attacks. He probably has the most of any Rider: He has one for every Shift Car, and even finishers for his Handle Sword and Door Gun.
- SpeeDrop: Type Speed's Rider Kick. In certain situations, Tridoron circles around the Roidmude and Drive while Drive faces away from the monster as tires surround it, spinning rapidly. Once they close in and shoot the monster forward, Drive jumps at the Tridoron and kicks off of it, then strikes the Roidmude, which sends him back to Tridoron, which happens multiple times until Drive comes in for the final kick. All other times, the SpeeDrop is basically a normal Rider Kick.
- JustiSmash: Type Speed Hunter's Rider Punch. Beforehand, Drive would imprison the monster with the Justice Cage, then tires appear and shoot Drive towards the cage, then does a loop-de-loop, and right when he's about to hit the cage, it goes away, allowing Drive to give the monster a powerful jab. During the fight with 005, the Monster can combine with the Justice Cage, allowing Drive to jump on it to crush whatever was trapped.
- Million Attack: Type Speed Vegas's finisher. Drive combines the Drum Shields with himself to join with the Dream Vegas Tire, and spin very much like a slot machine. Whatever the icon the wheels land on gets him the appropriate response, with all 7s getting him to shoot out a boatload of gold coins.
- Drift Slash: The finisher used by the Handle Sword, the effects of which vary based on the Shift Car used. Dream Vegas used in conjunction with three Turn slashes hits the foe for Triple 7, destroying the target.
- PerfecShot: The finisher used by the Door Gun, the effects of which vary based on the Shift Car used. Using the Shift Speed Car allows Drive to fire five shots and creating a giant tire out of energy, Drive jumps into the air and kicks the tire into the shots, enveloping them in flame and sending them straight into his foe.
- CannonCrete: Type Speed Mixer's finisher. It fires a salvo of quick dry cement, with emphasis on "quick", as it hardens upon contact with anything solid.
- MonsCrunch: Type Speed Monster's finisher. First, a tongue comes out of the Massive Monster Tire and brings it close to Drive so he can mash the target with giant energy projections of the Monster.
- Flare Stream: Type Speed Flare's Rider Shooting. This fires a barrage of fireballs at the target.
- Unknown: Type Speed Doctor's finisher. It speeds up Drive's healing rate and removes all ailments from his body... too bad he'll experience excruciating pain at the same time.
- DriRumble: Type Wild Dump's Rider Punch. This has Drive equip the Rumble Smasher and slams it at the opponent with the drill going off at high speeds to bore into the foe.
- Drift Rotation: An alternative Rider Slash with the Handle Sword. Turning the wheel on the Handle Sword followed by honking the horn as Type Wild, Drive spins rapidly, cleaving through his opponent with several spins around them. As Type Speed (as seen in the Ninninger vs. Drive special), this appears as a enhanced spin slash.
- Rescue Down: Type Technic Braver's Rider Kick. The Ladder Expander grabs the target and pulls them in towards Drive to kick. This finisher is first seen in the Kamen Rider #4 video series.
- Dead Heat Drop: Type Dead Heat and Dead Heat Flare's Rider Kick. Drive is surrounded by the Dead Zone aura and comes in for the kill, while Dead Heat Flare's version is with flames added to the attack.
- Formula Drop: Type Formula's Rider Kick. Drive glows blue and rushes in for a powerful kick, with the X-Fan Booster helping with the momentum of the attack. This is first seen in Drive's fight against Kamen Rider #4.
- Trailer Impact: The finisher of the Trailer-Hou. To activate it, two Shift Cars must be loaded inside of it while the Formula Shift Car is placed in a special slot above the barrel of the cannon. The finisher slightly depends on the Shift Cars loaded inside, with the most common being a powerful beam of energy.
- Trailer Big Impact: The finisher of the Trailer-Hou as Type Tridoron. To activate it, the Shift Tridoron must be loaded into it while Drive uses any Type Change Shift Car except for Shift Formula onto the special slot above the barrel. The resulting blast results in Drive shooting an energized Tridoron itself, but in doing so, transforms from Type Tridoron into the Type that is provided by which Type Change Shift Car he inserted beforehand.
Fusion Dance: Of the Power Booster / Two Beings, One Body variety. Shinnosuke combines with Mr. Belt, Tridoron, and all of the Shift Cars to become Type Tridoron, with Mr. Belt taking over sometimes.
Hand Cannon: The Trailer-Hou, usually reserved for Type Formula and Type Tridoron. This time, Mr. Belt has begrudgingly accepted the fact Shinnosuke would name it, Drive can fire powerful shots like a shot gun from this weapon. Like the others, the Trailer-Hou has a slot for Shift Cars to perform Full Throttle attacks. Unusually, it has multiple purposes.
- Type Formula has it where he has to load the Shift Formula Shift Car into the Shift Landing Slot, located on the top of the barrel, then loads two Shift Cars into the chamber of the cannon, then fire a blast of energy, the loaded Shift Cars altering the effects of the blasts somewhat.
- Type Tridoron has it where he has to load any that isn't Shift Formula into the slot, then loads Shift Tridoron into the chamber, getting Drive to fire an energized Tridoron at the opponent, transforming into what Shift Car he had used to put into the slot prior to the blast.
Luckily, My Shield Will Protect Me: He tends to use Justice Hunter's jail cell as one. As Type Wild, he tends to use the tire on his shoulder as a shield as well. The Door Gun also has a function like this.
Mid-Season Upgrade: Type Dead Heat and Type Formula.
Offhand Backhand: Type Technic literally has eyes in the back of his head, so he's a master at doing this. Special notice goes to its debut where it deactivates the monster of the week's device while shooting over his shoulder to hold them off.
Spam Attack: Drive's default Type Speed form is all about this: Its special attack, Turbo Smash, sweeps the enemy into the air and allows him to perform Rapid-Fire Fisticuffs, while his Rider Kick called the SpeeDrop has him trapping the enemy in a whirlwind of kicks from every angle.
Speed, Smarts and Strength: Drive's three primary forms specialize in these.
- Type Speed is, as the name suggests, specialized in high-speed combat.
- Type Wild is the strong form, sacrificing speed for higher physical strength and better defenses.
- Type Technic is the smart form, giving Shinnosuke Awesomeness by Analysis as well as the power to see things behind him.
Stuff Blowing Up: His first use of the then-incomplete Type Dead Heat involved a lot of spontaneous explosions, none of which seemed to have any connection to anything - they just popped up around him whenever he punched something.
Time Stands Still: In #6, Belt-san reveals to Shinnosuke that Drive can also cause Density Shifts. However, he never uses it in the entire show's run.

Krim Steinbelt/"Mr. Belt"

Portrayed/voiced by: Chris Peppler

https://static.tvtropes.org/pmwiki/pub/images/krim_steinbelt.png

https://static.tvtropes.org/pmwiki/pub/images/a903c8944fb86fbb245f94424e18c1e1.jpg

The developer of the Drive System and the Tridoron, who was also was involved in the creation of the Roidmudes. He was killed by Heart 15 years before the story begins, but he transferred his mind into the Drive Driver before his death. Shinnosuke often calls him "Mr. Belt"; a nickname chosen before Krim divulged his identity.

Affectionate Nickname: Shinnosuke likes to call him "Mr. Belt" (Belt-san).
Big "SHUT UP!": When he calls out Banno for torturing 002 and terminates their partnership.
Brain Uploading: He used to be Krim Steinbelt, but was killed by the Roidmudes (with one of them becoming Heart) and had his mind transferred to the belt, in order to fight them. This was also used by Banno, after he stole Krim's mind upload technologies.
Brainwashed and Crazy: Possibly after Roidmude 004 kidnaps him while Shinnosuke is weakened when Banno suddenly betrayed his own son, Go, Mr. Belt and Shinnosuke, and before Shinnosuke arrived once Banno completed the copy of Drive Driver for his use might be related to Surprise Future. Apparently to be true, as Banno had 004 implanted Mr. Belt with the "special" chip that makes him evil in Surprise Future, the same chip that turned the Roidmudes evil.
But Now I Must Go: He seals himself, the Mach Driver, the Shift Cars, the Signal Bikes, the Trailer-Hou, Tridoron and both bikes underneath the Drive Pit, but not before bidding farewell to Shinnosuke.
Character Tics: When possessing Shinnosuke in Type Tridoron, Krim often coughs into his hand.
Cowardly Lion: A braver example than most. When he feared a Roidmude uprising was imminent, he created his own android body to put his consciousness into so he could personally continue the fight against the rogue robots even after his death. However, his will proved too weak to activate ZZZ (in comparison to that of Zoruku "Ultimate Lupin" Tojo's, a master thief who was decades older than him). He then tried to delegate the responsibility of stopping the Roidmudes to his other secret Roidmude, 000 aka Proto-Drive, but his rigid methodology and his partner's stiff adherence to his directives resulted in them being outmaneuvered by the more fluid mental and physical evolutions of their enemies. After they team up, Shinnosuke helps Krim overcome his shame, doubts and fears, encourages the scientist to take more chances and think outside the box, culminating in him joining the fray (in a fashion) as one of the two consciousnesses controlling Type Tridoron during battles.
Death Is Cheap: Krim dies six separate times over the course of the show and movies, to the point of it nearly being a Running Gag. It may be a bit of commentary on the habit its predecessors had of creating drama by killing the protagonist's non-human partner in the last act.
Deuteragonist: Shares this position with Kiriko. Per Word of God, the idea for the two was to split that "buddy" role between two characters, with Krim functioning as Shinnosuke's partner as Drive.
Empty Shell: In the Bad Future, Eji Tomari uses a Drive Driver that is exactly like his father's except it doesn't have Krim in it as the scientist was killed years before from Banno corrupting his systems.
Equippable Ally: He built and, as a contingency for himself, is the Drive Driver.
Expy: Explicitly stated by Word of God to be one to KITT.
Fusion Dance: With Shinnosuke in Type Tridoron.
Future Me Scares Me: In Surprise Future. Later turns out to be Paradox Roidmude, who mimics his appearance.
Gadgeteer Genius: As Krim. These days, he can barely do anything physically, so he leaves the building to Rinna.
Gratuitous English: He often interjects English word and phrases. Being a Rider transformation device, at this point this is a given. It also helps that the VA's an English speaker.
He's Back!: Twice.
- From Movie War Full Throttle
  Belt-san: Okay Shinnouske! Start Our Engine!
- Then Suprise Future
Idiot Ball: Yes, Belt-san, tell Chase he doesn't need human emotions, its not like a Roidmude can come and give him...
Large Ham: Has No Indoor Voice for every single transformation announcement or special attack. Given that he's not just a pre-programmed voice, he's also (presumably) consciously doing this every time.
- In Surprise Future it is shown that he can talk to Shinnosuke while the Trailer-Hou's announcement is being spoken, so either he can talk with two voices at once or the transformation and special attack's announcement are pre-programmed
Lonely at the Top: Krim was a top scientist and one of the chief researchers behind the creation of the Roidmudes. Unfortunately, his devotion to his research didn't leave him much time for dating; he was single at the time of his untimely death during the Global Freeze.
My Greatest Failure: His role (as Krim Steinbelt) in the creation of the Roidmudes. While he didn't create the Roidmudes, he created the power source they use. He also allowed the creator of the Roidmudes to use said power source, even though Krim knew that the power source could cause Density Shift. It is later revealed that in their past he heard a ruckus coming from Banno's lab and finds out Banno's recent madness, Heart in the appearance of the investor who rejected Banno's project because of the risks and turned Heart into a puppet for his own satisfaction causing their partnership to fall apart and never trust Banno again.
Nice Job Breaking It, Hero: Post-series stuff repeatedly shows sealing all of his tech away wasn't his best idea in the long run, as Shinnosuke keeps needing his Drive powers as new threats arise, and thus either has to resort to other means or Belt-san has to get brought out somehow.
Oh, Crap!: He and Shinnosuke reacts this way when Chaser reveals in #5 he can use the Shift Cars by using poor Max Flare, who was only trying to help out.
- This is also his reaction to the appearance of Heart. Because Heart killed Krim Steinbelt and Proto-Drive.
- As well as 001.
Post-Mortem One-Liner: Nice Drive!
Posthumous Character: As a human. He was killed by the Roidmudes and uploaded his mind into the Drive Driver to "survive".
Pre Ass Kicking One Liner: Start your engine!
Properly Paranoid: His unwillingness to go public with Drive's identity or inform the police that the Kamen Rider is working for them might cause Shinnosuke frustration, but he has good reason. After all, the last time he shared technology with someone he thought he could trust, it resulted in the creation of the Roidmudes and the death of a lot of people, himself included. And as he points out to Shinnosuke, the Roidmudes could have eyes and ears anywhere, which happened with the Roidmude who copied Kyu (albeit benevolent), and with 001 who took the form of a government official with oversight over the police. Then again when he met Banno, who is now in tablet form, Mr. Belt thought Banno's darkness was still intact ever since he found out Banno had been abusing Heart before they were killed by the Roidmudes, and warned his allies not to trust him on the chance he's using his former colleagues and allies, including his own family to gather enough data to enact his evil plan (which resulted in stealing Roidmude #006's body to become Kamen Rider Gold Drive after Mr. Belt was kidnapped by #004).
Prophetic Names: We have a man named Steinbelt becoming a belt. Shinnosuke notes this once he learns "Belt-san's" real name in #10.
- The "Stein" part of the name is pretty prophetic as well, considering his involvement in making monsters that Turned Against Their Masters
Remote Body: He can use the Type Change Shift Cars in this manner. Same with Tridoron.
- He is also able to do this when Shinnouske obtains Type Tridoron.
Ridiculously Human Robot: He can sunbathe! He can cough! He can even drink milk (through the mouthplate on his display monitor, no less) with his only issue being that he needs a straw!
Robot Buddy: An intelligent belt-like device that aids Shinnosuke.
Running Gag: Keeps telling Shinnosuke things that should have been nice to know after they happen.
- Averted and joked about when he warns Shinnouske about the danger using Type Formula presents.
Screw This, I'm Outta Here: After witnessing Banno torture Heart in the most cruel ways he can think of, he ends his friendship with Banno. Banno thought he was joking.
Secret-Keeper: Something that causes increasing amounts of grief for Shinnosuke. He also keeps secrets from Kiriko, such as her brother being a Kamen Rider, until she learned and never thought her brother became a Rider after their reunion. Also keeps the recent revelation of Shinnosuke's true feelings towards Kiriko between Shinnosuke and himself.
Shipper on Deck: Thinks that Shinnosuke and Kiriko would be good together.
Super Prototype: Played With. The Drive Driver and Shift Brace are much more cumbersome (and far more picky when it comes to their users) than the Mach Driver Honoh which can access a majority of the powers afforded by the Shift Cars by itself. However, it has a higher storage capacity to accommodate a data packet as substantial as a complete digital copy of a person's consciousness such as Krim's. This is why Banno chooses to duplicate it over its technically more advanced successor. That, and it would cheese Krim his old colleague off.
Transformation Trinket: Works together with the Shift Brace to transform Shinnosuke and give him his powers.
True Companions: Views Shinnosuke as one. He's furious when he awakens from his near-fatal clash with Heart, chastising him for thinking that he could be replaced, since while there can always be another Drive, there can be only one Shinnosuke. And he makes him promise that if he should ever die, that Mr. Belt is right there with him, fighting until the end.
- This is also evident during the standoff with Heart. While Drive was trying to take off Mr.Belt, he wouldn't allow himself to be unbuckled.
- As the show goes on, he supports Shinnosuke even when he makes decisions that Mr. Belt might disagree with. Despite his insistence on Drive's secret identity, he backs Shinnosuke up when he decides to transform in public to protect Hayase and the hospital from Sword Roidmude.
Villain Override: A heroic example. Mr. Belt can remotely control the Tridoron with or without Shinnosuke's consent.
- Became a villainous example during Surprise Future.
Visual Pun: With a car based Rider, what else could this guy be based on but an actual seat-belt?

Kiriko Shijima

Portrayed by: Rio Uchida

The heroine of Drive, she is a cop belonging to the Special Crime Unit of the Metropolitan Police Department. She accomplishes her jobs and assignments mechanically, and her apparent reluctance to smile or laugh can make her seem frightening. In reality, she knows the true identity of Kamen Rider Drive, and she takes an active part in the fights as Shinnosuke's right-hand (wo)man.

Action Girl: Helps Drive out in battle.
Ascended Fangirl: Admired the original Drive for saving her, but due to his death she instead works on taking care of his successor.
Babies Ever After: Eiji Tomari (Shinnosuke's son from Surprise Future) says his mother rarely smiles and only does so if she's glad, heavily implying she eventually marries Shinnosuke and gives birth to Eiji. This is confirmed in the series finale.
Badass Normal: She was able to fight off three Roidmude before showing Shinnosuke how to transform... and she's just a normal human being.
Badass Family: Kamen Rider Mach (this season's Secondary Rider) is also her younger brother, Go.
Big Eater: She's able to eat a large bowl of ramen in one sitting, as well as a giant kakiage. This trait is one of the reasons Shinnosuke doesn't consider her girlfriend material. He's just fooling himself.
Catchphrase: "I'm taking you in!"
Clothes Make the Superman: In #16, she gets a pair of boots that dramatically improves her kicking strength.
Cold Ham: She is perpetually stoic even when making car puns or performing over the top action.
The Comically Serious: Her exaggerated stoicism generates most of her humor.
Dark and Troubled Past: A low-key example. Before the start of the series she encountered future Paint Roidmude. She was rescued by Proto-Drive, but because he died in battle her admiration for him pushes her to make sure Shinnosuke is a worthy successor for him. When she encounters that same Roidmude again she freaks out.
- Apparently as a child before the Paint Roidmude in her first adult year, her father has did something wrong on his own wife, her mother, witness how sad her mother is, causing both couple divorced for some bad reason Banno has on his own family, and both Kiriko and her mother should keep a young Go a secret, due to him too young to understand, until when he's finally grown as an adult, it's time to tell him a truth, shared to Shinnosuke and Krim about Banno's dark past, just in case if she's suddenly not around, or missing or kidnapped by the enemies.
Depleted Phlebotinum Shells: In #16, she gets special bullets that can penetrate a Roidmude's armor.
Deuteragonist: Shares this position with Krim. Per Word of God, the idea for the two was to split that "buddy" role between two characters, with Kiriko functioning as such for Shinnosuke's partner in police work.
Dull Surprise: Averted. While her character has this reputation, Rio Uchida is actually extremely expressive.
Fair Cop: She's a good looking Policewoman.
Good Is Not Nice: She is a scary and almost robot-like stoic young woman who's Establishing Character Moment involves handcuffing Shinnosuke for a minor offence but she is still unambiguously heroic and her opinion on Shinnosuke improves as the show goes on.
Happily Married: To Shinnosuke after Super Movie War Genesis. In Drive Saga 2, she is currently taking a maternity leave to takes care of the newborn Eiji and seems pretty content with it.
Hidden Depths: She's actually a pretty good artist, though most of her drawings are just a way of keeping track of Shinnosuke's habits.
- Her heavy pressure on Shinnosuke is due to her being saved by the original Drive. Since SHE can't become the Kamen Rider, she wants his successor to act like he does.
Hypercompetent Sidekick: Far more focused and driven than Shinnosuke, and doesn't suffer from the limitations of being a belt.
Kick Chick: Once she gains the Rear Cowl Boots, she can perform a Rider Kick on her own.
Locked Out of the Loop: Kiriko has no idea Banno's her father and Go guilt trips Shinnosuke into keeping it a secret. Then after Gou is brainwashed Chase lies to her, telling her that Go isn't brainwashed because he misinterpreted some advice Shinnosuke told him. Although in the end he was telling the truth though he didn't know it at the time.
Not So Above It All: Anything that has to do with Shinnosuke actually taking his job seriously has her smiling, and when she gets the Rear Cowl Boots she imitates Shinnosuke's Character Tic and even calls the attack a Rider Kick.
Official Couple: Ends up with Shinnosuke and marries him in Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis.
O.O.C. Is Serious Business: She is understandably terrified when she confronts the Paint Roidmude, due to the trauma she suffered when he attacked her in the past.
The Power of Trust: She never lost faith in Chase's innate goodness and sense of justice. Her undying trust in Chase pays off when he saves her life from Sword and becomes a Kamen Rider again in order to live up to being the Knight in Shining Armor she saw him as back when he was Proto-Drive.
Proper Tights with a Skirt: As a model police officer, this is a part of her uniform. But when it isn't...
Refused by the Call: Tried transforming into Drive after getting acquainted with Mr. Belt, but didn’t have the proper demeanour to use it. So they went after Shinnosuke.
Rescue Romance: #16 suggests she had a crush on Proto-Drive. Voice appeared as the man of Kiriko's dreams. The Roidmude was surprised to learn the Kiriko was seeing Chase.
Secret-Keeper: Is the only member of the SIU that knows Drive's true identity in the beginning. Later, Rinna joins this crowd, followed by the rest of the SIU after #25.
- Apparently she has an Awful Truth about her not so Dark and Troubled Past in her childhood. When she asked her mother about her father's whereabout, didn't intentionally mean to sadden her mother, realize that Banno is an Abusive Parent, she won't speak to Go about their father's darkness, due to him was still young to understand at his age. She reveals this to Shinnosuke and Mr. Belt.
She Cleans Up Nicely: Not that she looks unattractive in her police uniform, but when in #8 she meets Hayase for the first time in a civilian outfit, she looks really good.
- In #11, she dresses up for the Christmas party and, needless to say, hot !
- Now that her brother is in the cast, we'll probably be seeing a lot more of her in civilian clothing. Limited Wardrobe? Not any more.
Ship Tease: With both Shinnosuke and Chase, though the case with Chase seems to be more along the lines of hero worship.
- In the finale, it is confirmed she ends up with Shinnosuke.
The Stoic: Has a cold personality that borders on robotic.
- Not So Stoic: Shows this in #4 when facing her trauma caused by Paint.
Tsundere: Denies any allegations of smiling, even if she is legitimately happy.
When She Smiles: Shinnosuke is mindblown whenever she turns her lips up, and she vehemently denies it when it happens. It DOES look cute.

Rinna Sawagami

Portrayed by: Rei Yoshii

She is a scientist in electronic physics and an honorary member of the Special Crime Unit of the Metropolitan Police Department. She performs studies of the Roidmudes' powers, and helps Shinnosuke's investigations as the person in charge of the mechanics. She's also soon revealed to be the resident technician of the Drive Pit, helping to develop and maintain Drive's equipment. She is single and is rather impatient on the inside. She also has a bright personality, and is the mood maker of the SIU.

Gadgeteer Genius: Built devices that can detect the "Density Shifts"; and later ones that can counteract the effect. She also created a lot of Drive's equipment, and specialized bullets and kick-enhancing boots for Kiriko.
Genius Ditz: She normally acts like a flighty Genki Girl, but her inventions actually work, she managed to manipulate multiple police divisions while acting as a Fake Defector, and she developed Drive's weaponry. That said, her inventions do tend to have some rather odd quirks to them, which the characters often comment on.
Genki Girl: She's always in good spirits and with a smile on her face. The only times she isn't is when she's brought down by relationship issues, making upgrades for Drive and Mach causing havoc on her sleep schedule, and when she was run ragged in #4.
Hidden Depths: She wants a romantic relationship; partly over concerns about getting past her prime and partly because she's not completely over a prior breakup.
Labcoat of Science and Medicine: Wears one being the resident scientist.
Mad Scientist: Because of their creators' love of motorized vehicles, Krim and Harley's inventions are shaped like cars and bikes, but otherwise operate normally once activated. Rinna takes the gimmick to bizarre extremes with inventions like the Door Gun (which can only be reloaded by opening AND closing the door on its side), Handle Sword (which needs to have its wheel spun to activate its finisher), and Signal Ax (which requires the user to wait for a short period of time before they can use its finisher like they would in an actual street crossing) among others. Even among her fellow Large Ham inventors, Rinna is noticeably more excitable and manic.
Old Maid: #16 and #17 show that she's worried about becoming one. This is the driving force of her conflict with Genpachiro during the Heart half of Kamen Rider Drive Saga: Kamen Rider Mach/Kamen Rider Heart because he's dragging his feet when it comes to proposing to her.
Secret-Keeper: As it turns out, she's actually Drive's head mechanic.
- Secret Secret-Keeper: Shinnosuke is initially unaware of this.

Kyu Saijo

Portrayed by: Kenta Hamano

He is a network student and an honorary member of the SIU. He is a digital expert who possesses a huge amount of network-related books, and he is talented at information-gathering. His occult hobbies enter slightly dangerous areas, and his approach towards cases is sometimes frowned upon by the whole unit.

Animal Motifs: Bats. He has poor eyesight, shrieks a lot, stays up late at night, and the Bat Viral Core soundbite is played whenever he does or says something acutely weird. Fittingly, he's replaced by Bat-type Roidmude 072 for a brief period of time after the Christmas episode.
Berserk Button: If anything causes him to lose his valuable data, he'll become hellbent on getting revenge.
Butt-Monkey: If it isn't Genpachiro getting jokes at his expense, it's Kyu-chan. Best seen back in the Paint Roidmude case, where he falls off the ladder he was on at a snail's pace and after the Gunman case, where he gets assaulted by two girls over wanting info from Go.
Creepy Doll: Often seen with stuffed dolls from Murmur Mansion, an anime he is a fan of.
Doppelgänger: Had one in Roidmude #072. He ended up portraying the real Kyu perfectly to the point where he could have been working inside the SIU's office and the others wouldn't have known about it. He was ultimately killed by Medic for being "defective".
Geek Physiques: He's not exactly fit and tends to tire easily when doing work in the field.
Hidden Depths: Sure, he's eccentric and a bit creepy, but his heart is good enough that when a Roidmude copied him, it turned good.
Meaningful Name: Kyu Saijo comes from the Japanese word for "Superior" (Saijoukyuu). Turns out it's not his real name.
Nerd Glasses: They fit nicely with his otaku persona.
Online Alias: "Kyu Saijo" is apparently this. His real name is Kenta Imai.
Otaku: Of the occult.

Jun Honganji

Portrayed by: Tsurutarou Kataoka

He is the section chief of the Special Crime Unit of the Metropolitan Police Department. He is a political centrist who really hates trouble, and orders Kiriko to keep an eye on Shinnosuke because of his habit to skip work. He is interested in fortune-telling and feng shui, and the color of his necktie matches the lucky color of each day.

Aside Comment: He does this a lot.
Bunny-Ears Lawyer: At times the Chief seems like he's far more competent than he lets on. In #6, he tells Shinnosuke about the driver whom he had saved as Drive earlier, had returned the favor, returning his motivation and allowing him to activate Type Wild. And he did this JUST when it was most needed.
- In #11, he seemingly has a random conversation with a friend about some favor that he was owed, while Shinnosuke and Kyu are discussing how to get access to a potential lead who's in prison. Turns out that whoever it was was able to get Shin time to interview the Copycat Pirate, whom had information in Volt's case. As Kyu put it afterward: "He's an enigma, wrapped in a mystery."
- Turns out he's a trusted colleague of Krim Steinbelt and knew Shinnosuke was Drive the whole time.
The Captain: Of the SIU.
Large Ham: Has a speech quirk, as well as tends to make melodramatic or exaggerated motions.
Obfuscating Stupidity: It's unclear how much of his quirkiness is real, but he's been in on the loop the whole time without anyone but Krim knowing, and set up the SIU for the express purpose of allowing Drive to work within the police.
- From #26 onward, some of his quirks are still there but much less exaggerated, suggesting that he intentionally played them up to divert suspicion.
O.O.C. Is Serious Business:
- Shinnosuke and Kyu were completely floored when he shows off his office politics skills in #11.
- In #33, when Nira tells him to stop joking and try to find a new Kamen Rider, the chief just breaks down, leaving the goofy persona for that moment.
Put on a Bus: Gone on vacation from #16 on, during which he's replaced with a cardboard cutout. Kiriko notes in #18 that he was only supposed to be out for one week, but by that point had been gone for three. He apparently spent some time playing golf and currying favor with his superiors, allowing the team a little leeway in later missions.
Secret Secret-Keeper: When Drive's identity is publicly exposed, it turns out he already knew! He kept this from Shinnosuke, Kiriko, and Rinna.
Team Dad: He most often finds himself playing peacemaker. #3 even had him go into fortune-telling to help dissuade conflict.
Signature Device: His flip phone.

Genpachiro Otta

Portrayed by: Taira Imata

He is the assistant police inspector belonging to the Metropolitan Police Department's first investigation division. A very active detective, he has been dispatched from his division to liaison with the Special Crime Unit. He thinks that the work of the SIU is completely terrible, mocking it as an "occult club". He has a sharp tongue, but he is a competent detective whose methods surprisingly match Shinnosuke's. In reality, there is an childish side to him, and it's the one thing he doesn't want anyone to know.

Accidental Misnaming: Repeatedly messes up the word "Roidmude". #32 reveals that this is due to 001's memory-altering powers, and when he's administered the antidote he can finally get it right.
Ace Custom: The Heavy Acceleration Particle Measuring Device he commissions from Rinna has the ability to let him move during Density Shifts and grants him a measure of immunity against electrical attacks on top of having all the normal functions of the previous model and a much sleeker design; the associated helmet also resembles a police siren rather than a dish with blinking lights attached to it.
Agent Scully: In the first few episodes; to such an extreme that he disbelieves in Slowdown, a widely experienced and acknowledged phenomenon, even while he's in the middle of experiencing it himself. He starts turning his opinion around after seeing a Roidmude for real in #5, and by #12 has become an...
- Agent Mulder: To the point that he insists Slowdown is involved with a crime even when the rest of the SIU says there's not enough evidence. He was later proven right.
- This brutally justified in #32 when it's shown that THE ENTIRE POLICE FORCE was subjected to memory-alterations of anything Roidmude related, making their Arbitrary Skepticism completely unintentional.
Brick Joke: Early in the show, Gen ends up in positions where he only sees a bit of Drive's body at a time, and each time while he's in a different form. His artist's rendition of Drive thus has Type Technic's head with Type Speed's arms and Type Wild's legs. Over a year later, the Kamen Rider Heart movie briefly makes the mashup into an actual form.
Butt-Monkey: Can find himself being made the butt of jokes most of the time.
Can't Catch Up: He's got the drive and desire to fight Roidmudes once he acknowledges their existence, and is even willing to wear any of Rinna's stupid-looking inventions to that end, but he can't really keep pace with the Riders physically and Rinna keeps giving all her real top-notch equipment to Shinnosuke and Kiriko.
Character Development: His transformation from Agent Scully to Agent Mulder over the course of the first 12 episodes.
Crouching Moron, Hidden Badass: While the plot might force Gen to be comic relief, when he finally gets the spotlight, he shows that he's just as good as Shinnosuke.
Contrived Coincidence: When he's part of the action the plot goes to ridiculous lengths to make sure Gen's knocked unconscious so he can't figure out Shinnosuke and Go are the Kamen Riders. Until #25, that is, thanks to the Sword Roidmude attacking a hospital.
Determinator: The Running Gag is eventually revealed as the sign of one: Gen was forcing himself to remember that Roidmudes existed, even though Freeze's ability meant he was physically incapable of having that thought. Indeed, it comes up repeatedly that Gen's determination is his greatest virtue, both in the show and in the Kamen Rider Heart/Kamen Rider Mach movie.
Driven by Envy: Played very much for laughs, concerning Public Safety in #5.
Friend on the Force: With the normal police, since the protagonists are a Ragtag Band of Misfits on a SIU.
Hoist by His Own Petard: Very nearly gets himself killed when his bullet got deflected back onto him thanks to the Crash Roidmude.
Jerk with a Heart of Gold: He loves kids... not that he wants anyone to find out.
- That being said, he looked like he was going to go ballistic when his personal unit laughed at the SIU in #12.
- As the series goes on, his loyalty to the SIU only increases, and in #25, he tells Shinnosuke that no matter what happens, he'll always have his back.
Malaproper: As noted under Running Gag, he can't seem to remember the name "Roidmude", instead calling them things like "Hemmoroido". Lampshaded in #27 where, when infected by a Roidmude's Hate Plague, he angrily rants that the other members of Special Crimes think he's an idiot for doing this... while still doing it. Later on, we learn it's justified, as the entire force is brainwashed to not remember.
The Nicknamer: To wit: Kyu is "Kyu-taro", Kiriko is "little lady", and Rinna is just "Doc". Apparently Honganji and Shinnosuke, being the closest to detective rank like him, warrant being called by their proper names. Or he just can't remember them all.
Not So Above It All: He seems to be pretty excited about seeing Kamen Rider, he dresses up in costume during a Christmas party, and when an actress asks the SIU for protection, he claims he's the actress's biggest fan.
Running Gag: He often sees Kamen Rider at the scene - but only part of him at a time, leading to a wildly inaccurate image. He's seen Type Speed's arm, Type Wild's legs, and Type Technic's face. He gets further confused when he sees a picture of Mach, not realizing that there are two Kamen Riders running around. And then when he sees Drive and Mach together, he thinks that Types Wild and Technic are also separate Kamen Riders.
- His other running gag is that he always mispronounces the name "Roidmude". Justified, as the entire force was brainwashed into not focusing on them.
That One Case: Featured in #18-19, where he and his mentor went after the owner of a revenge-by-proxy website.

Others

Go Shijima/Kamen Rider Mach

Portrayed by: Yu Inaba (live), Jun Watanabe (Suit)

https://static.tvtropes.org/pmwiki/pub/images/go_shijima.png

Kiriko's younger brother, a freelance photographer who returns to Japan for urgent business. He transforms using the Mach Driver Honoh. Unlike Drive, Mach's motif revolves around bikes, which aligns him more to a traditional Rider, though he has a secondary theme revolving around road signs. His various forms change the sign on his chest.
