Main Characters

    Eiji Hino/Kamen Rider OOO 

Eiji Hino/Kamen Rider OOO/Eiji Greeed

Portrayed by: Shu Watanabe (live), Seiji Takaiwa (suit)
The main protagonist. A world-traveling vagrant with no family, dreams, or long-term career, whose recent stint as a museum guard for the Kougami Foundation ends with him taking possession of three Core Medals and the OOO Driver, allowing him to turn into Kamen Rider OOO and fulfill his subconscious impulse for helping people.

Tropes that apply to him in general

  • All-Loving Hero: He's very selfless to the point of helping others when needed and he will risk his life to protect the ones he care for.
  • Baleful Polymorph: Is forced into fully transforming into a berserk, mindless Greeed by Dr. Maki in Episode 46. Fortunately he managed to return to his true self come next episode.
  • Beware the Nice Ones: Episode 43 shows how scary Eiji can be when he is angry.
  • Broken Hero: Very much in the front running for being quite possibly the most broken Rider in the entire franchise. Now remember the kind of emotional baggage Riders from the Showa Era had to deal with and really think about this for a second.
  • Character Development: Goes from a lonely wandering vagrant who's spurred on by pure Chronic Hero Syndrome to a hero who truly learns to resolve for himself again and accept the help of those around him.
  • Catchphrase: "Seiya!"; during his Early-Bird Cameo in Kamen Rider W Forever A To Z The Gaia Memories Of Fate he says "Riders should help each other out", which seems to have become his Catch Phrase for crossovers.
  • Character Tics:
    • Holding his hands out like a tiger in TaToBa and LaTorRatar forms, or really any forms with the Tora Claws. Also, him saying "SEIIIIYAA!" during finishers.
    • To a limited extent, his henshin pose of slashing his arm downward. He does this even when transforming into Birth.
  • Color-Coded for Your Convenience: Incorporates more purple into his wardrobe later in the series as he gradually becomes more Greeed-like.
  • Crouching Moron, Hidden Badass: Ankh thought he'd make Eiji his sock puppet; turns out underneath his naive and carefree persona is someone who won't back down even unto death and, when given the power, can fight.
  • Determinator: Put someone's life in danger and there's nothing he won't do to protect them.
  • Drunk on the Dark Side: Power to save people was what Eiji always wanted. So he decides he needs to get power, no matter the means or costs.
  • Dunno What's Going On But...: When offered the OOO Driver, he pretty much states that he doesn't know what's going on but if it helps him save lives, he'll do it.
  • Glowing Eyes of Doom: Eiji's eyes glow purple after he absorbs the Dinosaur Medals. This only happens when their power reacts to something.
  • Godhood Seeker: Kougami's agenda is to get Eiji to succeed where the original OOO failed — by absorbing the thousands of Cell Medals within the Foundation's vault.
  • Good Is Not Dumb: Ankh gave Eiji the OOO Driver, believing he's an impressionable pawn. But come Episode 2 Eiji not only proves him wrong, but also showed a considerable level of cunning.
  • Goofy Print Underwear: These seem to be the only type of underpants he's capable of owning.
  • The Hero: of Kamen Rider OOO of course.
  • I Let Gwen Stacy Die: Episode 2 reveals an embittered side beneath his laid-back behavior — his zeal for saving people stemmed from memories of a young girl he befriended during his travels, whom he was unable to save during a civil war.
  • Idiot Hair: One is briefly shown in Episode 2 prior to receiving a text from Hina and revealing his deeper, troubled past.
  • Image Song: Time Judged All, which he shares with Ankh. It also serves as the theme of Tajadol combo.
  • Loyal Phlebotinum: The OOO Driver will only work for him because he's the one that broke its seal.
    • Though this is largely an Informed Ability said by Ankh. We haven't seen what (if anything) would happen if someone else tried to use the OOO Driver.
    • One can theorize that like a Sengoku Driver the belt wouldn't activate.
  • Nice Guy: Eiji is a kind individual who is willing to help people out regardless of their status.
  • Martyr Without a Cause: Whenever Eiji is given the option to use Medals, he often takes the most dangerous approach and uses a Medal Combo without regard for the situation, even though they take a severe toll on his body when unprepared. Date confirms from witnessing Eiji's behavior firsthand that he's self-destructive in his goodwill, rushing to help lives without actually valuing his own. This persists when he continues to rely on the dangerous Purple Medals in order to protect everyone - even after Character Development leads to him realizing and embracing his own desires, he still goes to self-destructive lengths to pursue them.
  • Motive Decay: Discussed in the story. Eiji used to genuinely and actively desire to help others. A traumatic experience with a village he visited lead him to lose this sense of ambition, and by the time the series starts he's just a traveler who helps people not out of a desire for change but because he has nothing to do but take their wants onto himself. It's only until later in the series that Eiji remembers his original goal of wanting to protect everyone, and that Ankh was actually able to help him achieve it.
  • Obfuscating Stupidity: Played for Laughs in Episode 3 where he threatens to "not be able to resist doing something stupid" and throw away the OOO Driver to force Ankh into releasing Hina. Subverted, as his natural personality just seems stupid despite him being extremely clever.
  • Oblivious to Love: Hilariously Lampshaded in episode 18, where it takes a lot of hinting to find out the victim of the week was in love with a man, and still, Ankh gets it faster than him.
  • Parental Abandonment: Inverted and justified, given what his father was willing to do to him for votes.
  • Red Oni, Blue Oni: The red to Goto's blue.
  • Rich Idiot With No Day Job: Subverted. He used to be an emissary for his politician father, with a genuine desire to help people. Unfortunately, his father used the money he donated to the African village he was in to fund a civil war which killed a girl he befriended, which he exploited to earn votes. This traumatic incident robbed him of all desire, turning him into a self-sufficient wanderer helping people along the way.
  • Rummage Sale Reject: Let's just begin with how oversized his clothes are. This could also apply to most Random Combos, with colors that may or may not clash.
  • Samaritan Syndrome: "If I don't reach out my hand when I can, the regret will make me wish I were dead."
  • Screaming Warrior: Probably tied with Kenzaki for how much he screams while fighting. SEIYAAAA!!!!!
  • Sense Loss Sadness: Apparently a sign of him becoming a Greeed.
  • Shell-Shocked Veteran: The civil war that killed a friend of his not only left him the sole survivor due to being a politician's son, but also helped his father earn votes without even caring for his feelings. He grew into a jaded man with no desires, allowing him to become OOO (specifically, with the Red, Green, Yellow, Gray and Blue Medals) without losing his mind. Unfortunately, the Purple Medals feed on the desire of nothingness, explaining why it turns Eiji into The Berserker. The money he donated to the village was secretly being used to fund said civil war, making him indirectly responsible for it and the casualties of it.
  • Stepford Smiler: Episode 32 reveals he's a Type B — despite initially having grand aspirations to help others, he became embittered after being unable to stop the civil war that killed a girl he knew, which was being funded and orchestrated by his politician father. This lead to Eiji becoming a man without any personal desire or ambition - though he puts on a smiling face around others, it later becomes clear he has no sense of self-preservation and places his worth in fulfilling the desires of the people around him. The emptiness in his heart is such that the Purple Medals, which desire only nothingness, are drawn to his complete lack of personal desire.
  • Tragic Keepsake: Keeps Ankh's cracked Taka medal after the battle with Dr. Maki.
  • Walking the Earth: A closer look at his spare change in Episode 1 reveals currency from other countries (including an American quarter), and in Episode 3, he can be seen in the background of a photograph taken in the middle of a desert. He also states in Episode 1 that he doesn't have a fixed address and often isn't even in Japan. Turns out he used to be a traveling emissary on behalf of his father. At the end of the series he left Japan once again, and a year later, updates his friends through webcam on his whereabouts, unknowingly being accompanied by Ankh's spirit — somewhere in the desert.
  • You Are Not Alone: A major part of his growth as a character is realizing this. Happens more directly in the finale after Ankh performs a Heroic Sacrifice to allow him to use TaJaDol against Maki, only for Eiji to find out quickly that he's literally fighting alongside Ankh's spirit. Even though he doesn't know it, Ankh never leaves him.

Tropes exclusive to him as Kamen Rider OOO
Taka, Tora, Batta: Ta-To-Ba! Tatoba, Ta-To-Ba!
  • Absurdly Sharp Blade: The Condor Medal with the Raptor Edges, and it's gold Palette Swap counterpart, the Shocker Medal.
  • Armed Legs: The Leg Core Medals give OOO's legs special powers.
  • The Berserker: Like FangJoker, PuToTyra was extremely difficult for Eiji to control. Of course, he does eventually manage to tame the form.
  • Blade Below the Shoulder: The Kamakiri Medal with the Kamakiri Swords.
  • Blessed with Suck: The five purple Core Medals inside his body. Eiji has enough of the medals to use the PuToTyra Combo, by far the strongest in terms of power (in fact, strong enough to shatter Core Medals), and the medals themselves are sentient enough that they can emerge from his body on their own to be used if Eiji is ever in mortal danger. On the flip side, it will send him into a mindless rampage that drains his strength more than normal combos. While it became possible for him to control it, it's difficult to maintain that control and the combo is less powerful when restrained. Their presence in his body also causes Eiji to turn into a Greeed.
  • Boxing Kangaroo: The Kangaroo Medal. Unlike the other Core Medals, this one can be used as either an arm or leg Medal and gives OOO a different power depending on which body part its being used as.
  • Chest Insignia: The O Lung Circle, which displays pictures of the Medals currently in use and lights up during a Finishing Move.
  • Combat Tentacles: The Tako Medal.
  • Combo Platter Powers: Well, yes, quite literally. As OOO, he has the power to mix and match the Medals, giving him three to use at any one time. As evidenced in Episode 6, Full Combos (GataKiriBa, LaToraTah, SaGoZo, TaJaDol, ShaUTa, PuToTyra and BuraKaWani) are much more powerful than Random Combos (including the default TaToBa), albeit at the cost of leaving Eiji completely spent afterwards.
  • Cool Sword: The Medajalibur, a sword that quite literally cuts through reality...and fixes any collateral damage right afterward.
  • Crimefighting with Cash: Whenever he uses Cell Medals (which cost about a yen each) to power his weapons.
  • Deadly Upgrade: The PuToTyra Combo (See Blessed with Suck).
  • Doppelgänger Attack: The GataKiriBa allows OOO to multiply himself to attack.
  • Dual Wielding: The Arm Core Medals give OOO two weapons on each arm, except the Kujaku Medal.
  • Earthquake Machine: The Zou Medal.
  • Elemental Powers: OOO's full colored Combo forms each have elements that match the Greeed their Medals come from.
  • Finishing Move: Several. The finishers themselves have elements of Combo Platter Powers. For instance, with Head Medals, the Taka Head has OOO target the enemy with a scope before attacking, while the Lion Head charges his attacks with glowing energy. Also, with Leg Medals, the Batta Legs are leaping attacks, while the Cheetah Legs are rushing attacks.
    • Combo Forms
      • TaToBa Combo: TaToBa Kicknote 
      • GataKiriBa Combo: GataKiriBa Kicknote 
      • LaTorarTar Combo: Gash Crossnote 
      • SaGoZo Combo: SaGoZo Impactnote 
      • TaJaDol Combo: Prominence Dropnote 
      • ShaUTa Combo: Octo Banishnote 
      • PuToTyra Combo: Blasting Freezernote 
      • TaMaShii Combo: TaMaShii Bombernote 
      • BuraKaWani Combo: Warning Ridenote 
      • Super TaToBa Combo: Super TaToBa Kicknote 
    • Random Combo Forms
      • LaKiriBa: OOO leaps into the air with the Batta Legs. Then, he blinds the enemy with the Lion Head's power. Finally, OOO performs a mid-air cross slash with the Kamakiri Swords.
      • TakaKiriTah: OOO locks on to the enemy with the Taka Head's power. Then, after producing three rings (one red, another green and the third yellow) between him and the enemy, OOO dashes through them and executes a cross slash with the Kamakiri Swords.
      • ShaGoriTa: OOO does a powered up version of the Gori Bagon's long range attack.
    • Weapon finishers
      • Medajalibur: OOO Bashnote 
      • Taja Spinner: Magna Blazenote 
      • Taja Spinner: Using any combination of seven Cell or Core Medals in the Taja Spinner, OOO launches a wheel of energy at the enemy. Power is dependent on the number of Cores used.
      • Medagabryu Bazooka Mode: Strain Doomnote 
      • Medagabryu Axe Mode: Grand of Rage
  • Fire-Breathing Weapon: The Kujaku Medal with the Taja Spinner.
  • Fun with Acronyms: The movie-only TaMaShii Combo, which could also be read as 'tamashi' or soul.
  • Gravity Master: SaGoZo can manipulate gravity.
  • Hand Cannon: Medagabryu, the main weapon of PuToTyra Combo.note 
  • Horn Attack: The Sai Medal.
  • An Ice Person: PuToTyra can create cold winds that can encase enemies in ice. When Eiji becomes a Greeed, he gets this power as well.
  • In a Single Bound: The Batta Medal.
  • Incendiary Exponent: When he performs TaJaDol's "Magna Blaze" Giga Scan, he ignites into a firebird and rams the opponent from the air.
  • Infrared X-Ray Camera: The Cobra Medal.
  • Kill It with Ice: When summoned and wielded by a different Combo form, the Medagabryu can use ice-powered slashes.
  • Klingon Promotion: The show's Grand Finale sees Eiji use TaJaDol Combo to destroy the purple Core Medals once and for all, and with them the PuToTyra Combo that they granted him as his final form. Eiji eventually reclaims a full set of the other Medals, but the purple ones remain destroyed in canon movies, with the result that TaJaDol claims the mantle of OOO's final form for itself. Even in works that disregard this aspect of OOO's canon, TaJaDol continues to have an elevated place, such as being the only form to have its own Ridewatch canonically appear in Kamen Rider Zi-O.
  • Law of Chromatic Superiority: The all-red TaJaDol Combo is the only one that changes one of the parts when fully equipped to give it a unified phoenix motif, also making it the only Combo explicitly based off a mythical animal. It's portrayed as considerably stronger than the other Combos, and has a unique weapon that lets it use the powers of other Medals. That said, it can't do everything, and all of the other Combos as well as various non-Combo arrangements have situations where they're much better suited for dealing with the current opponent. However, in the end it's TaJaDol that proves able to do what the all-purple PuToTyra Combo couldn't.
  • Light 'em Up: The Lion Medal can emit an intense light.
  • Luckily, My Shield Will Protect Me: The Kame Medal with the Goura Guardners.
  • Making a Splash: ShaUTa can liquify his body, as well as shoot water from his helmet.
  • Man Bites Man: The Wani Medal with the Saw Deadscythers.
  • Meaningful Name: The way his name is pronounced is a portmanteau of the Japanese word for "king" and the English word "zoo", and the way it's spelled is meant to represent power beyond infinity and the use of three Core Medals in each form.
  • Mid-Season Upgrade: TaJaDol Combo.
  • Musical Assassin: Burahngi, the main weapon of BuraKaWani Combo.
  • Mythical Motifs: In general, OOO has chimeras, though less the specific greek animal, and the more general concept of "fusing aspects of various animals together." More specifically, TaJaDol and PuToTyra are based on a Phoenix and a Dragon, respectively.
  • Non-Elemental: BuraKaWani is the only combo without some form of element involved.
  • One-Man Army: According to the novel, using OOO's full power was enough for him to stop a war singlehandedly.
  • Our Dragons Are Different: PuToTyra is themed after animals that in the modern world are purely conceptual, combining extinct dinosaurs with mythological creatures. Each individual core is based on a specific real world genus but when combined, and particularly when he's on a rampage, they create the imagery of a European dragon.
  • Peacock Guy: As TaJaDol.
  • Playing with Fire: TaJaDol can shoot fireballs with the Taja Spinner.
  • Power Fist: The Gorilla Medal with the Gori Bagōn, crossing over with Rocket Punch.
  • Power Gives You Wings: The Ptera Medal with the External Fins.
  • The Power of the Sun: LaTorarTar can emit a scorching heat.
  • Set Bonus: OOO's full color Combos each give him an extra power otherwise unusable in Random Combos. The purple Medals notably cannot be used with other Medals, due to their special properties.
  • Shock and Awe: The Kuwagata Medal can generate lightning from its horns, while the Unagi Medal uses electrified whips.
  • Shockwave Clap: SaGoZo has the ability to generate extremely powerful shockwaves by beating his chest like a Gorilla.
  • Shoulders of Doom: The Tricera Medal with the Wind Stingers, and the Imagin Medal with the Orenotsuno.note 
  • Story-Breaker Power:
    • Not only is GataKiriBa monstrously powerful on its own thanks to being able to produce a seemingly limitless number of clones, each just as powerful as the original, but with enough number of other Core Medals, those clones can switch into other Combos. It's also horrendously intensive on the effects budget. As such, Eiji never gains access to it except when he would be absolutely unable to defeat an enemy otherwise.
    • PuToTyra is the only combo he has that could permanently kill a Greeed, so naturally this is the one that's the hardest to control and is a double-edged sword. Otherwise, the story would be over in another two episodes.
    • Super TaToBa deserves a special mention, as in addition to being a much more power version of the original TaToBa and giving him stats on par with the aforementioned PuToTyra, Eiji can stop time because the medals that gives him access to this form are displaced in time.
  • Super Not-Drowning Skills: The Shachi Medal.
  • Super Senses: The Taka Medal has telescopic vision.
  • Super Speed: The Cheetah Medal.
  • Swiss Army Weapon: The Tyranno Medal with the Tail Divider and Legsteranail.
  • Time Master: Super TaToBa can temporarily stop time.
  • Tron Lines: Lights are shown running across the colored (non-black) parts of OOO's body when he's seen transforming or after activating a Scanning Charge.
  • Weaponized Headgear: The Head Core Medals give OOO's head special powers.
  • Whip It Good: The Unagi Medal with the Denki Unagi Whips, crossing over with Shock and Awe.
  • Wolverine Claws: The Tora Medal with the Tora Claws. The Ganbaride games reveal a white Palette Swap version of this Medal called the Panda Medal.
  • Word Purée Title: All the combo names, default, random or official. And with words from two languages to boot.


Ankh/Shingo Izumi's body

Portrayed by: Ryosuke Miura (live), Eitoku/Satoshi Fujita (suit, hand)
Shingo Izumi
The Bird Greeed and a dishonest wildcard who was released along with the other Greeed — in the form of his right arm. After encountering Eiji and turning him into OOO, he takes over the half-dead body of Shingo Izumi, a police detective whom Eiji met earlier in the story, to become his temporary vessel even as he keeps an eye on Eiji.
  • And I Must Scream: Ultimately averted with Shingo — he was conscious all along while his body was taken over by Ankh, but this has no effect on his psyche once he temporarily regained control of his body during Episodes 41-43, and once he returns to his body for good at the finale.
  • And Then What?: To the other Greeed in regards to becoming complete. Unlike the others, he's come to realize that becoming complete is a moot point because that still won't satisfy them, and that he realized he desires something more: to be alive.
  • Animal Motifs: Birds
  • Anime Hair: His mohawk-ish hairdo is curled on the right side, braided on the left side and mostly straight in the back.
    • One might even call his hair feathered.
    • The hair kind of makes sense when you compare him with the other Ankh, who is missing the right side of his head.
      • Moreso once one sees his complete form. He's still asymmetrical and the crest on his head resembles his human hairdo.
      • And then there is also his new hairstyle in the "Let's Go Kamen Riders" 40th year anniversary movie, which he gets while he is possessed by Momotaros.
  • Anti-Hero: Type V. He's only helping Eiji against the other Greeed because it's in his own best interests, and has no qualms about who is hurt so long as he gets what he wants. He slowly mellows out into a Type II.
  • Anxiety Dreams: His nightmare of losing to lost Ankh speaks to his fears of being weak, of losing his identity, and perhaps even of losing Eiji as a partner.
  • Backup from Otherworld:
    • After performing his Heroic Sacrifice to enable Eiji to utilize TaJaDol in the Final Battle, his spirit appears and fights side by side with Eiji, even aiding in the Finishing Move. Afterwards, his spirit continues to follow and watch over Eiji.
    • In Movie Wars MEGAMAX, Ankh comes back from the future to help Eiji battle Kamen Rider Poseidon; this gives Eiji hope, since it means someday he will restore the cracked Taka Medal. By the time of Heisei Generations FINAL six years later, he succeeds. Sadly, it only lasts until the end of that movie, yet Eiji at least knows how he can revive him. He just has to find a way to make it stick.
  • Barehanded Blade Block: Manages to do this against PuToTyra's Medagabryu in Episode 34.
  • Being Evil Sucks: The only Greeed to not just realize just how lousy an existence being one really is, but want to do something about it.
  • Bishōnen: In his human form. His actor is certainly easy on the eyes, that’s for sure.
  • Blood from the Mouth: Shingo, when very near death.
  • Boomerang Bigot: A rare heroic example. By the end of the show, Ankh is disgusted at the single-minded nature of his kind and fully acknowledges that it even applies to himself.
  • Butt-Monkey/The Chew Toy: One of the few villainous examples. He gets hurt in a comical fashion, including being crushed under a vending machine, kicked, hit by a flying Tako Candroid, and getting flipped over by Hina.
    • Played for Drama in Episode 8, where he gets beaten half to death by Uva, has two core medals stolen from him, gets rocks thrown at, and having to crawl to Eiji for some cell medals.
  • But Now I Must Go: After waking Eiji so he can be saved from his fall and thanking him for helping him become a living being, Ankh's spirit starts flying away and says Eiji doesn't need to his help anymore before vanishing into half his broken Taka Core. Subverted kind of, because Ankh's spirit remains with Eiji without his knowledge, but a Tear Jerker regardless.
    Ankh: I'm not the hand you need help from anymore.
  • Calling Your Attacks: The only live character to indulge in this so far, when he whacked Gamel on the forehead to escape his grasp.
  • Character Tics: "*Tch*"
  • The Chessmaster: While he makes some pretty creative attempts, he is not that good at judging people. Too bad his "pawn" Eiji turns out to be a little more cunning than he expected him to be.
  • Deadpan Snarker: Oh so much. He is fond of making snide remarks as much as he is fond of ice cream.
  • Death Glare: He seems to like giving this to people. That, or it's his default expression. Notably in Episode 13, he scares a little boy just by staring at him like this.
  • Demonic Possession: Done by attaching himself like a glove.
    • Puppeteer Parasite: Shingo is his puppet, and removing Ankh too soon will kill Shingo in minutes.
  • Deuteragonist: He gets his own character arc throughout the series and is nearly as prominent as Eiji.
  • Does Not Like Spam: He understandingly doesn’t like eating poultry.
  • Ear Ache: How Hina manhandles him.
  • Earn Your Happy Ending:
    • After all he went through the entire series, he ultimately becomes alive and gains a spirit, allowing him to both die happy and follow Eiji in spirit form after his death.
    • Same goes for his host, Shingo. He reclaims his body for good and returns to a normal life with Hina.
  • Enter Stage Window: Notably in Episode 17. Might be justified because he is the bird Greeed.
  • Evil Mentor: At the start, Ankh has no interest in saving people. He just wants enough Cell Medals to reconstitute a full body. Ultimately, he can't keep it up.
  • Expository Hairstyle Change: Much like the Imagin, Shingo's hair turns into a blonde mess only when Ankh's possessing him.
    • It gets even crazier when Momotaros's own expository hair change kicks in when he attaches his severed left arm to Shingo's body in The Movie, as seen in the image link under Anime Hair above.
  • Fashionable Asymmetry: A minor example, his T-shirt is mostly white with a single red sleeve. Most of his other attire follows this as well.
  • Faux Affably Evil: Among his fellow Greed, he's the worst at faking a personable facade and he arrogantly dropped the act almost immediately after taking over Shingo Izumi's body because he thought he wouldn't need to play nice to control Eiji.
  • Fighting from the Inside: Even after being absorbed by Ankh (Lost), Ankh retains enough will to freeze up his devourer's right arm.
  • Ghost Memory: Ankh is able to access Shingo's memories while inhabiting his body.
  • Good Wings, Evil Wings: Played with. Multicolored wings represent angels in Islamic art, which is odd for a character that's morally ambiguous at best.
  • Good Is Not Nice: By the end, he's still not remotely nice, nor is he really heroic, but he still does everything he can to save Eiji and help him save the world from Maki, including dying.
  • Guile Hero: While largely lacking in combat power compared to Eiji, Ankh is much better at judging a situation and deciding what Medals will best solve the problem at hand, whereas Eiji defaults to just using Combos for everything if left to his own devices.
  • Guyliner: Given the Egyptian theme he seems to have going for him, it makes sense.
  • Hammerspace: He's a living one. He's composed of far more Medals than his body could logically hold, plus kept the OOO Driver inside himself.
  • Heel–Face Revolving Door: The last act sees Ankh realize he's turned face, turn heel for a few episodes, then turn face again just in time for the Grand Finale.
  • Helping Hands: Due to losing nearly all his Cores, he's been reduced to an arm, but is still able to function perfectly well without a body... and fly.
  • Heroic Sacrifice: While Ankh was already dying by that point, in the end he uses up the last of his strength to let Eiji become TaJaDol Combo once more and destroy Maki and the Medal Vessel once and for all.
  • Hidden Depths: Somehow, he ended up being a right forearm, while the rest of him is a completely separate entity. Even he and the rest of his body seem confused as to how this happened until #30.
  • I Have the High Ground: Likes hanging out in trees and other high places, which is completely natural since he's the Bird Greeed.
  • Image Song: Time Judged All, which he shares with Eiji. Fittingly, it also serves as the theme to Tajadol, the combo created from his medals.
  • Improbable Aiming Skills: He's able to throw medals with such skill that he's thrown one right into the OOO Driver slot...from across the battlefield, past a swarm of Jellyfish Yummy! Justified, as long-range accuracy is the Taka Medal's innate power.
  • Improbable Hairstyle: Looks very hard to maintain for someone who was pretty much homeless for the first few episodes. Especially obvious when he jumps into a river in #15, and arrives just a few minutes later looking as polished as usual.
  • Ineffectual Sympathetic Villain: While not really evil, Ankh does change sinds a few times. He gets sick of working with the other Greeed rather quickly because their quest for power isn't going to fill the void within them.
  • It's All About Me: Part and parcel of being a Greeed. He released the Greed to get a shot at reforming himself and spends most of his time loudly proclaiming his own self-importance. Not even his own body is spared his selfishness as he callously ditches Shingo Izumi's mortally wounded form when it suits him and actually abandoned his original one to die in an attempt to steal his Core Medals from the original OOO centuries before.
  • Jerkass: Ankh is thoroughly self-centered, rude, misanthropic, and he bordered on being out-and-out sociopathic early on. He couldn’t give a damn about who ends up getting affected so long as he gets what he wants. Slowly but surely, he develops into a very rough Jerk with a Heart of Gold. He‘s not any less of a selfish jackass, but he does wind up doing the right thing, even sacrificing himself to help Eiji in the final battle. And while he’ll never admit it, it’s pretty clear he does gradually grow to care about Eiji and Hina.
  • Large Ham: Shows this at times, normally when he's actually happy for once, such as when he got his Kujaku Medal back. He really hams it up when playing the Great Leader of Shocker in Kougami's movie.
    • In the net movies for Let's Go Kamen Riders; just watch him Freak Out when he sees there are no more popsicles, or how loud he gets when he proclaims that the secret to the show's success is "Me, ANKH!!"
  • The Last Dance: Heads back to help Eiji in the Final Battle with Dr. Maki and Uva despite the fact that the former dealt him a fatal blow by cracking his Taka Core.
  • Literal Split Personality: He and Ankh (Lost) seem to have this. Where he is cunning and manipulative, his other half is childish and singleminded.
  • Meaningful Name:
    • In Egyptian, "ankh" means "eye of the hawk", fitting as he's the Bird Greeed.
    • In a nod to its etymology, the Taka Medal is used as OOO's head part.
    • It's also the name of the Egyptian symbol of life, he's the only thing keeping Shingo alive (and later, becoming truly alive has become his true desire). His theme Ankh The Greeed seems to support this as it is Egyptian themed.
  • My Species Doth Protest Too Much: Unlike the other Greeed, he came to realize how pointless their quest of becoming complete is, because even that won't fill the void within them. He's becoming frustrated with how his kind seem completely unaware of this and is sick and tired of being one. Having Eiji thank him for letting him become OOO seems to have triggered a clearer Heel Realization.
  • Nice Job Fixing It, Villain!: He thought Eiji would make for a good dimwitted puppet, but wound up having given the O Driver to the perfect candidate: someone much more cunning than he lets on, with no worldly desires other than to help people. In so doing he saved the world, and himself.
  • Not So Different: From Kazari, which is why he turns down the offer to work together. He can't trust someone who's as sneaky as he is.
  • One-Winged Angel: After collecting four of his Core Medals and re-absorbing them all, he briefly sprouts a literal single wing on the right side of his back but is unable to regenerate completely since the rest of his body is a separate entity.
    • Played straight later, after Ankh (Lost) is destroyed and he's absorbed some of Kazari's Cores. It allows him to assume his Greeed form despite using Shingo's body as a base. The first time he actually does it is to fight Eiji in Episode self-defense after Maki forces Eiji to perform this trope. Even with only three Cores, he's capable of this.
  • Odd Name Out: The other Greeed all have names stemming from a desire, or at the very least, a verb. Ankh's means "eye of the hawk" and it's also the Egyptian symbol for life.
    • Word of God has it that during production stages, his name was "Asshu", from "Assuru"/"Dominate", i.e: desire for authority. It still fits him even now.
  • Playing with Fire: It takes most of the show for Ankh to regain enough power for it, but once back at full strength he's quite capable of slinging fireballs.
  • Posthumous Character: Ankh's "host", Shingo Izumi. Though Shingo slowly recovered back to perfect health while being possessed.
  • Power Fist: Even after regaining his full power, Ankh prefers to use his human form in combat most of the time, manifesting only his Greeed wings and right arm. He treats the arm as one of these.
  • Power Gives You Wings: When he regains two of his Cores, he gains a single energy wing...and that's it. It takes him most of the show to get the other back.
  • "The Reason You Suck" Speech: Delivers one to the other Greeed in #45 about how empty their entire motivation really is.
    Ankh: Medals, Medals, Medals. Don't you have anything else?
    Uva: I don't see the problem, you're the same way!
    Ankh: Yeah...I am. And it's garbage! Being with you all makes that clear. Take these, and get lost!
  • Redemption Equals Death/Redemption Earns Life: The other Greeed, for all their intellect, were ultimately nothing more than piles of coins, and their remains returned to being nothing more than that. Ankh is the only Greeed to have died because he was the only one to have lived.
  • Red Right Hand: Literally; it's all there is to him!
  • Right Hand Versus Left Hand: He and Eiji sometimes don't exactly clue each other in to important details (like when Kougami offered Eiji one of Ankh's medals). Also literally from Episode 25 onwards, due to Ankh's left arm creating the Yummy for the arc. Another (smaller) example would be in Episode 35, where Shingo temporarily gains control of his body and tries to save Hina from the Unicorn Yummy.
  • Rocket Punch: Performs one in Episode 13 when fighting Goto by launching himself off his host's arm and punching him in the face.
    • Also uses a similar technique to gather Cell Medals whenever Eiji defeats a Yummy.
  • Secretly Dying: He keeps the fact he's been mortally wounded by Maki hidden from everyone (except Hina). He says he's hiding it so Eiji won't worry about him during the Final Battle. Eiji doesn't realize it until after Ankh already performed his Heroic Sacrifice and he sees the cracked Core himself.
  • Token Evil Teammate: Ankh loudly and constantly reminds his companions that yes he is only using them to gain power and that he will totally betray them when it comes down to it. By the end of the series he grows out of this. He's not nice, never that, but he's no villain either.
  • Trademark Favorite Food: Popsicles, so much so he's willing to steal a few from children. In Episode 15, Chiyoko presents Eiji with Ankh's popsicle bill of ¥23,625 (~$280). In the same episode, Eiji goes so far as to promise Ankh a year's worth of popsicles if he helps him save Hina. As it turns out, the reason he's so addicted to them is that actually tasting food is a completely new experience for him. Greeed normally can't taste anything, but due to possessing Shingo's body, Ankh gained the ability to do so. When Eiji eventually finds out, he regrets his efforts to curb Ankh's popsicle intake.
  • Unexplained Recovery: Shingo, in the end. He reclaims his body for good, and returns to a normal life.
  • Vitriolic Best Buds: With Eiji. Sure, they frequently undermine one another's goals to advance their own, but at least they're upfront about it.
  • Villainous BSoD: Goes into one (of the Heel Realization variant) at the climax of Episode 46, when Eiji thanks him for helping him rediscover his desire: to help people. Ankh instantly stops attacking him and freezes up at the notion.
  • Wakeup Makeup: Ankh takes this to the extreme in Episode 13. As if the ever-present Guyliner and Improbable Hairstyle weren't enough, he even sleeps fully clothed, including shoes.
  • You Are Not Alone: After he performs his Heroic Sacrifice, his spirit appears to fight along side OOO in the final battle, giving a smile pretty much telling Eiji this.
  • You Will Be Assimilated: Ankh and the rest of his body try this on each other at the end of Episode 29. And the other Ankh was winning before Eiji intervened.
    • Happens again in Episode 40, only this time, both Eiji and Hina are unable to stop Ankh from getting consumed by Ankh (Lost). Three episodes later, however, Ankh (Lost) is killed, allowing Ankh to absorb what's left of him to try to regain his true power.
    • And then again in episode 45 when Ankh reveals his plans to assimilate Shingo to not only make up for his three lost Core Medals and become complete once more, but also to permanantly retain his human senses in order to gain a sense of being.


International Cuisine Restaurant Cous Coussier

    Chiyoko Shiraishi 

Chiyoko Shiraishi

Portrayed by: Marie Kai
Owner of the Cous Coussier, a cosplay restaurant themed on international cultures.. She hires Hina on account of her Super Strength, and later (and on Hina's recommendation) Eiji on account of his knowledge of foreign cultures garnered from the years he spent as a world traveler.
  • Cloudcuckoolander
  • Crouching Moron, Hidden Badass: Most of it happens offscreen, but Hina's reaction to her beating the tar out of a group of mind-controlled police officers implies there's more to her than just The Ditz. In this case, though, she was also really angry.
  • The Ditz
  • Kansai Regional Accent
  • Locked Out of the Loop: Eiji had to give her a well-made excuse about Ankh being raised on the streets so she wouldn't find out about his true nature. She goes onto believe the story until Episode 47.
  • Morality Pet: Displayed all the traits of being one for Dr. Maki, except he turned out to be so fundamentally screwed up that meeting her made him much worse!
  • Surprisingly Good English: A few of her lines at the end of Episode 10 when she tries to teach Ankh etiquette and table mannersnote  certainly count. Not one bit of accent when she used English.
  • Unlimited Wardrobe: The restaurant switches themes every other week, and Chiyoko somehow has enough outfits for herself and whoever she's employed at the time.

    Hina Izumi 

Hina Izumi

Portrayed by: Riho Takada
Shingo's younger sister. After learning from Eiji of what became of her brother, she urged him to join her as a coworker at the Cous Coussier, not only because of his extensive knowledge of foreign cultures (which the restaurant uses as its cosplay themes), but also to look after her brother's body, now occupied by Ankh.
  • Ambiguously Human: It's been hinted this could be the reason for her strength.
  • Does Not Know His Own Strength: Occasionally. Especially evident in Episode 28, where she tries to hug Eiji and nearly snaps him in two.
  • Earn Your Happy Ending: Her brother regains control of his own body for good and they return to their normal lives.
  • Extremity Extremist: Her Super Strength is strictly focused in her arms.
  • The Fashionista: She goes to a fashion design college and even won an internship in France, but declined the offer due to her brother's condition. In the finale, while Shingo accompanies her to school, they notice two high school students, one of whom carries a strange switch-like device.
  • Locked Out of the Loop: Averted. Eiji tries to make up a story about Shingo being on an undercover operation, but that lie gets blown almost immediately. He finally tells her the whole story in Episode 4.
  • Riddle for the Ages: Her Super Strength is never explained.
  • Secret Keeper: For Eiji and Ankh. During the Final Battle, she's also the only one other than Ankh himself that knows Ankh is Secretly Dying, as Ankh told her not to tell Eiji.
  • Ship Tease: It's shown several times that she deeply cares for Eiji. And, at other times, for Ankh. She even made personal chocolate Valentines for them both.
  • Super Strength: You wouldn't expect this until we see it for the first time, lifting a giant vending machine when she assumed Eiji got his foot crushed (it was actually Ankh getting crushed)...and then dropping it when she see Ankh's hand emerging from under it.
  • Younger Than They Look: Hina's actress was only 15 at the time the show was made.


Kougami Foundation

A company that has been researching on the Greeed since they found a sarcophagus containing them in their art museum. Also seems to fit the Omniscient Council of Vagueness trope. There main goal seems to be harnessing the power of the Core and Cell Medals for the betterment of mankind. The members are as follows:
    Kousei Kougami 

Kousei Kougami

Portrayed by: Takashi Ukaji
The very eccentric president of Kougami Foundation. A firm believer in the power of desire and the beauty of the birth of all things, good or bad, he is also known for his odd habit of making birthday cakes whenever he's not bending Ankh, Eiji or the other Greeed to his will.
  • Adam Smith Hates Your Guts: Your cute and useful Robot Buddy Candroid? That will cost you Cell Medals. The Ridevendor Cool Bike? That will also cost you Cell Medals. The privilege to pay him Cell Medals to use Kougami Foundation products? That will also cost you a fixed percentage of your Cell Medal income on top of the Cell Medals you would have spent if he hadn't taxed you. Keep in mind, while the Cell Medals prices aren't that high, they need to be paid for each usage of the above. It's all for a good cause (by Kousei's estimation) and he doesn't really have it out for the protagonists; it's just that people are easier to control and goad when they owe you. Eventually, he reveals exactly what he was saving all those Cell Medals for, and it turns out to have been crucial to saving the day.
  • Alliterative Name: Kousei Kougami.
  • Ambition Is Evil: Inverted in his personal philosophy. He believes that desire is a force of progress and evolution and encourages it in his subordinates.
  • Batman Gambit: Tricks Gara into making a Deal with the Devil with Eiji, knowing full well that Eiji's void of desire would overload Gara's Doomsday Device.
  • Big Good: A rare example in Kamen Rider of a CEO of a powerful corporation who genuinely wants to help the heroes because it's right. He's a little...odd, but compared to the Sonozakis...
  • Bunny-Ears Lawyer: He out-negotiated a living embodiment of human greed. There's a reason this guy's a CEO and not a patissier.
  • Catchphrase: HAPPY BIRTHDAY!!! Also WONDERFUL!note 
  • The Chessmaster: He's expected everything that has happened thus far, he even outwitted Ankh, a living incarnation of greed and a cunning trickster himself.
  • Large Ham: Full stop! None can beat him in hamminess in the show.
  • Luke, I Am Your Father: The Kamen Rider OOO Wonderful movie reveals that he is the descendant of the first OOO. This factors into his desire to see Eiji succeed where his ancestor failed to do — become a god.
  • OOC Is Serious Business: His encouragements to destroy the purple medals, rather than celebrate their "birth" shows just how dangerous they are.
  • Real Men Cook: One of his consistent and notable traits is cooking cakes.
  • Red Oni, Blue Oni: The red to Dr. Maki's blue.
  • Romanticism Versus Enlightenment: Stands on the "enlightenment" side of growth and progress.
  • Too Dumb to Live: He himself describes Oda Nobunaga as the most wickedly ambitious man in history...and then clones the guy using Cell Medals. Let's re-iterate: the most evil and ambitious man ever, brought back to life using condensed human greed.
  • Trademark Favorite Food: He hasn't been seen eating much yet, but he very much enjoys making birthday cakes.
  • The Wonka: He runs a company invested in the phlebotinum that constitutes/powers the series' monsters, and sits around baking cakes. And did we mention, "HAPPY BIRTHDAY!!!!"
  • You Didn't Ask: Despite knowing pretty much everything about the events of 800 years ago, he seems to only reveal the information when someone is looking for it. Possibly justified, as he believes desire is the most important thing in the world, so it makes sense he only provides information if someone desires it.

    Erika Satonaka 

Erika Satonaka

Portrayed by: Mayuko Arisue
Kousei's personal secretary who procures cakes and maintains a businesslike attitude.
  • Action Girl: She shows in Episode 20 just how badass she really is when she uses a shotgun and a pistol to wipe out a small army of Mooks singlehandedly. Maybe her Big Eater abilities weren't the only reason Kougami hired her... And Kougami even makes her Goto's backup after Date passes onto him the mantle of Birth.
  • Big Eater: During Episode 14 her temporary replacement is seen to have collapsed halfway through his tenth cake, which is the size of a small cake one could buy from a grocery store. Kougami laments that the replacement, while doing everything he could to wolf down the cake, is not at Satonaka's level. One wonders how on earth she manages, and if her Hammerspace is in fact in her stomach.
    • Also take notice that she hates sweet things, and is more into spicy foods. One has to wonder how she is able to literally stomach all that sugar.
  • The Fashionista: She loves looking good even in battle, so she takes a long time to dress up before going out to fight, much to Goto's annoyance.
  • Guns Akimbo: In Episode 20, she arrives to help against the latest Yummy armed with a pistol and shotgun.
  • Instant Expert: Date and Goto have to train like crazy just to use the Birth Buster; Satonaka gets one out of necessity and has no such problem. Though it is on a lower setting, so it's justified.
  • Let's Get Dangerous!: She's normally quite unassuming...then Kougami told her to go help OOO and Birth with a Yummy. Cue her arriving on a motorcycle armed with a shotgun and pistol and proceeds to kick butt.
  • Ms. Fanservice: Her Cat Girl costume at the Halloween party in episode 9.
  • Punch-Clock Hero: Only shows her Action Girl credentials when Kougami asks her to. Even when she's officially reassigned as Goto's support once he takes over as Birth, she turns off the Yummy-detecting Gorilla Candroid when she's on her break. Goto had to offer her a percentage of his pay in order to get her to be on-call and ready to deploy at all times.

    Kamen Rider Birth Users 

Kamen Rider Birth

Portrayed by: Eitoku

An experimental Kamen Rider suit using the expendable but common Cell Medals, as opposed to OOO and his rare Core Medals.

  • All Your Powers Combined: Birth Day.
  • Armed Legs: Caterpillar Leg.
  • Awesome, but Impractical: The CLAWS Scorpion is incredibly powerful, but requires a total of 1000 cell medals to use, thereby depleting a good chunk of Birth's user's reserves.
  • Chest Blaster: Breast Cannon.
  • Combining Mecha: CLAWs Scorpion.
  • Cool Guns: Birth Buster.
  • Finishing Move: Cell Burst
    • Birth Buster: After connecting the Cell Bullet Pod to the barrel of the Birth Buster, Birth shoots an explosive ball of energy at the enemy.
    • Breast Cannon: Breast Cannon Shootnote 
    • CLAWs Scorpion: Fires an array of various colored lasers from the tip of its stinger.
    • Birth Day: Cell Bashnote 
  • Fun with Acronyms: Birth's weapons are referred to as the Birth CLAWS, or the Cannon/Leg(s)/Arm/Wing System.
  • Grappling-Hook Gun: Crane Arm.
  • Hammerspace: Averted, the Birth system runs on Cell Medals, so it user has to carry the Medals around in something (for Date, a large can and for Goto, a backpack) wherever they go.
    • However, the Birth Buster, on the other hand, seems to be pulled out of nowhere. Subverted, however, as unlike most Riders were the weapon is formed with the suit, instead of just forming a new one after giving his Birth Buster to Goto, he had to go have a new one made.
    • Played straight with the CLAWS and the suit itself, as the components that are assembled into the suit and weapons come out of roughly baseball-sized orbs that they could not realistically fit into.
  • Law of Inverse Recoil: Suprisingly averted. The Birth Buster has a huge recoil, enough to knock an unprepared person off their feet. Date has just practiced and knows how to use it properly.
  • Meaningful Name: Birth is actually based on a birthday cake, which is made clear by being a blank suit that is then given various attachments.
  • Motion Capture Mecha: CLAWs Scorpion, to a degree. It's clearly motion controlled and mimics the Birth user's movements to a degree, but obviously takes a few liberties due to the fact that Birth moves like a human while the Scorpion moves like ... a scorpion.
  • Razor Wings: Cutter Wing.
  • Selective Magnetism: The Birth CLAWs can automatically draw in Cell Medals (but not Core Medals).
  • Shovel Strike: Shovel Arm.
  • Super Prototype: Averted, as the prototype version of the Birth Driver has only a few of the functions of the later model, and is used as a backup when the main driver is damaged. Then Date returns, and takes the prototype in order to back up Goto.
  • This Is a Drill: Drill Arm.

Akira Date

Portrayed by: Hiroaki Iwanaga

The first full-time wielder of the Birth system and, like Eiji, a world traveler who only came back to earn funds for his travels.

  • All There in the Manual: In-series — the manual of the Birth suit includes information on Ankh and Eiji. By his own words, it appears Kougami expected him to read it and didn't brief him much.
  • Blood from the Mouth: Spits up blood when badly injured by the Greeed, causing Goto to think he died.
  • Bounty Hunter: He was hired by the Kougami Foundation to get a hundred million Cell Medals to be paid, which requires him to hunt down and destroy Yummy and Greeed. This is simular to real life bounty hunters, who are technically, by law, hired to hunt down the bail of the person, represented physically by the person.
  • Catchphrase: "Now's the perfect time to cash in" and "Time to get to work".
  • Combat Medic: Date was once part of a team of doctors that traveled the world. His nickname was something along the lines of the "Fighting Doctor". In the finale he returns to Africa to resume his work.
  • Didn't Need Those Anyway!: The Proto-Birth suit only comes with a few of the CLAWs parts that the final model did, but fortunately for Date they're the only parts he knows how to use anyway.
  • Didn't See That Coming: His reaction to OOO GataKiriBa's clones transforming into the other six single-colored (and TaToBa) Combos.
    "Wow. Didn't expect those reinforcements."
  • Disney Death: In Episode 38, when he's seemingly killed by the Greeed. It turns out he actually faked his death to give Shintaro the drive needed to replace him as Birth.
  • Dunno What's Going On But...: While not a Punch-Clock Hero like Satonaka, he originally doesn't come off as someone all too interested in the politics of fighting the Greeed and, instead, just does it for the money.
  • Fake Defector: Turns out it was an act, based on Kougami's orders, to keep an eye on Dr. Maki and help get Goto in the right mindset to take over as Birth.
  • Gratuitous English: "Goto-chan, come on!", "Goto-chan, nice!"
  • Hidden Depths: While we don't know what he wants his money for, it's implied that it's something important, at least to him.
    • Episode 37 implies he wishes to use the money to fund medical schools in the country which experienced a civil war that involved him and Eiji; this is used as his motivation for his faux-Face–Heel Turn. However, episode 38 reveals that he needs it to fund his own surgery to remove the bullet in his skull. Subverted once more in that he returns to being a doctor in Africa when the series ends after his surgery, letting him work directly on helping people again.
  • Image Song: Reverse/Re:birth, which he shares with Goto.
  • Instant Expert: Averted, unlike most Kamen Riders, he needs an instruction manual to know how to use the Birth suit. He does mention that he hates reading through manuals though, and prefers to learn from practical experience.
  • The Last Dance: It's revealed that he became Birth because he's dying — he has a bullet lodged in his brain. However, he returns in Episode 46, fully recovered, and rejoins Goto as Birth Proto Type.
  • Malaproper: Refers to several different bird Yummies as chickens, which Goto has to correct him on.
  • Malicious Misnaming: Mistakes Ankh's name as "Anko" (which means red bean paste, also a female Japanese name), and keeps addressing him as such throughout the series, usually in a playful way.
  • Meaningful Name: Birth Date.
  • Mr. Fanservice: Shown off in Episode 24 when he takes off his shirt to use in some emergency First Aid.
  • Older Sidekick: He is in his thirties, younger than Kougami, but noticeably older than most Kamen Riders. Ironically, he's Goto's mentor.
  • Perpetual Poverty: His contract with Kougami has a 1:1 exchange rate for Yen and Cell Medals. There are a number of problems with this arrangement. First, Date can't cash out his Cell Medals in increments; he has to hand over 100,000,000 or he'll get nothing at all. Secondly, the Kougami Foundation needs to be given a net amount of 100,000,000 Cell Medals; that is, the gross Date hauls in with deductions applied. Next, the Birth system and its weapons require Cell Medals to be activated and need even more of them to boost and combine their powers; as the battles against the Greeds and Yummies grow more intense, Date finds himself having to borrow Cell Medals from his bosses just to stay in the fight. Lastly, defeated Yummies produce a few hundred Cell Medals at most, so even if he didn't spend more Cell Medals than he earned during each encounter, he'd have to defeat thousands of fully-grown Yummies to meet his quota. As a result, he's perpetually indebted to the corporation he sought to profit from.
  • The Bus Came Back: Returns to join Goto with the Kamen Rider Birth Prototype.
  • Real Men Hate Sugar: He doesn't seem to like sweets, as he flees the Cous Coussier when it has a dessert fair.
  • The Rival: A more friendly version than normal for Kamen Rider, and it's not really towards OOO but to Ankh. Eiji doesn't really care about Cell Medals and just really wants to save people, and is even willing to join forces with him whenever necessary; it's Ankh that is really in conflict with Date.
    • Even Ankh lightened up slightly when he realized that Birth is only interested in Cells and not Cores. And really, name one person Ankh isn't hostile towards.
  • Shoo Out the Clowns: Leaves before the show's comedy rate drops as the plot reaches its climax, though he does come back.
  • Suspiciously Similar Substitute: He was handpicked by Kougami to be Birth and shares several similarities as well as a common history with Eji.
  • Trademark Favorite Food: Oden.
  • Wrestler in All of Us: He'll use pro wrestling moves and grapple Yummies to the ground when he's unarmed.

Shintaro Goto

Portrayed by: Asaya Kimijima

Sole survivor of the Kougami Foundation's 1st Ride Vendor Motorcycle Brigade and a former police officer.

  • The Apprentice: Goto starts training under Date to replace him as Birth for whenever he finishes his job.
  • Call to Agriculture: Returns to his job as a cop in the finale.
  • Character Development: Big time. Once Kougami told him his pride is one of the reasons he was denied the chance to become Birth, he decided it's about time he swallow his pride and learn some humility by becoming a waiter at the Cous Coussier, as well as ask Date to make him his apprentice.
  • Chick Magnet: During his stay at Cous Coussier, he was popular among the female customers.
  • Everyone Has Standards: One reason he was initially denied the chance to become Birth is because he objected to Dr. Maki's unscrupulous ways.
  • Good Is Not Nice: Before his Character Development set in. He gets a lot better.
  • The Gunslinger: He's been shown using a pistol, a shotgun, and even gets a Birth Buster when Date takes him as his apprentice. He even gets a shoulder-mounted rocket launcher in one episode!
  • Heroic Wannabe: He joined the Kougami Foundation to help save the world - and spends the first part of the series grumpy because Eiji's doing all the fighting while his assignments are only to observe and make deliveries.
  • Hidden Depths: Implied; as he was the only survivor of the Foundation's motorcycle patrol, he was Shintaro was Kougami's first choice for who would use the Birth System.
  • Image Song: Reverse/Re:birth, which he shares with Date.
  • Jerkass: Pre-Character Development, he's generally abrasive towards Eiji.
  • Never Got to Say Goodbye: Subverted — he cannot bring himself to say goodbye to Date, believing they will see each other again. And see each other again they did, because The Bus Came Back and Date, now fully recovered, now joins him and OOO as Birth Proto Type.
  • Read the Freaking Manual: Unlike Date, Goto did, and upon acquiring the Birth Driver starts pulling out numerous functions of the suit and its various weapons that Date didn't know it had. He also dismantled the self-destruct mechanism that Maki snuck in on the sly.
  • Red Oni, Blue Oni: The blue to Eiji's red.
  • Sidekick: To Date after he starts training.
  • Took a Level in Badass: After finally succeeding Date as Birth, Goto takes a million levels in badass.
  • Took a Level in Kindness: Went from being a prideful Jerkass who was resentful and cold toward Eiji to a determined hero and one of his closest allies.


How well does it match the trope?
