[[folder:Riki]]

!!! '''Voiced by''': Creator/ToshihikoSeki (1st OVA and Drama CD), Creator/KentaroIto (2nd OVA and Drama CD), Darren Mitchell (English)
[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/135249.jpg]]

A unique looking black-haired mongrel from the Ceres slums widely known as "Riki The Dark" for his proud and defiant nature. He is also the leader of the Bison gang. Eventually, he very reluctantly becomes the Blondy Iason Mink's Pet. He struggles with accepting his life as a Pet having been such a headstrong and independent gangster.

----
* AdaptationDyeJob: His eyes are made brown in both [=OVA=]s rather than the black they are described to be in the novel.
* AintTooProudToBeg: He was stubbornly too proud at first to ever beg for anything but then after ''instrumental conditioning'' with the Pet Ring, he became this trope. Not that he would ever admit it.
* AllOfTheOtherReindeer: Treated poorly by the other Pets of Eos save for Mimea.
* {{Angst}}: So much and [[JustifiedTrope completely justified]].
* BadassBiker: Used to be, before meeting Iason.
* BadassDecay: Invoked through BreakTheCutie and BreakTheHaughty over the course of the story.
* BecameTheirOwnAntithesis: Compare and contrast slum mongrel Riki in his youth with Guy to submissive pet Riki at the end not wanting to leave Iason's side. Complete acceptance as a pet which he once saw as the worst possible thing ever.
* BeCarefulWhatYouWishFor: Riki wanted to leave the slums at all cost, thinking it would lead to a better life. He ended up living in the Eos Tower of Tanagura, and found that the extravagantly luxurious home of the Elites turned out to be worse to him than the slums ever were.
* BeYourself: This was very important to Riki and he struggled with it to hang onto his crumbling {{Pride}}.
* BigDamnHeroes: In the 1st OVA series for all of Bison and for Kirie in the 2nd OVA series.
* BornUnlucky: You could say all mongrels are born unlucky but Riki's life takes the cake.
* BreakHisHeartToSaveHim: Attempted this and failed horribly.
* BreakTheCutie: Iason broke him completely after three years.
* BreakTheHaughty: The gist of his character arc in one sense. As everyone who knew him in Ceres can attest, Riki was a prideful if not arrogant person in his heyday as a Bison (albeit less so than they might have expected). But then came three years of having his pride incrementally tattered by Iason. By the time he returns to the slums, he's noted to be a shell of himself by former admirers... though he hangs onto some measure of pride until the very end.
* BrokenBird. After was taken by Iason as a pet.
* ByronicHero: Even after he had become a BrokenBird.
* CannotSpitItOut: Riki is usually tight-lipped rather than speaking the truth of matters.
* CantGetInTroubleForNuthin: As a Pet, Riki often caused trouble in hopes he'd be discarded by Iason. Rarely worked as his behavior only excited Iason.
* CombatPragmatist: He's a gangster so fighting dirty is not beneath him.
* ComplainingAboutRescuesTheyDontLike: During his attempt to [[BreakHisHeartToSaveHim push Guy away to keep him safe]].
* CoolPeopleRebelAgainstAuthority: He's well-known through of out Ceres for this and he is proud of it.
* CurtainsMatchTheWindow: It's a plot point because his pure dark hair and eyes are a trait only Onyx Elites would have.
* DarkSecret: That he's a Pet [[spoiler:and in love with his Blondy master.]]
* DeadpanSnarker: Has his moments. Especially with Iason.
* DeathGlare: Kirie, Luke, various Pets, Iason and other Blondies have all been targets of Riki's burning, angry stare.
* DefiledForever: Tells Guy this. He never got back together with Guy as he didn't want Guy to see what kind of a lewd and lascivious person he had become via Iason's training.
* DrowningMySorrows: Prone to doing this.
* DudeMagnet: Riki really isn't aware of how attractive he really is.
* EarnYourTitle: Riki The Dark. Very well-earned.
* FatalAttractor: To some extent. Most of the people that want him have very serious issues to work out and he always ends up paying for it.
* FirstLove: First and only love for both Guy and Iason.
* GoGoEnslavement: As a pet.
* GoodOldFisticuffs: He gets into a lot of fistfights.
* AGoodWayToDie: [[spoiler: Died on his own terms.]]
* GroinAttack: [[spoiler: He frequently suffers from this, given the effects of the Pet Ring. Then Guy takes the ring off via a penectomy.]]
* HeKnowsTooMuch: In the novel concerning Tanagura's darkest secret.
* HellBentForLeather: He is a biker. So much so that Iason decides Riki's Pet outfit should also be made of leather.
* HeroicBSOD: Upon seeing Iason again at Mistral Park after he had been freed.
* HotBlooded: He used to be, but it's not completely gone.
* HumbleHero: Of the slums. Riki made Bison renowned in Ceres and was treated as a hero for it but [[ThinkNothingOfIt he didn't care about any of that]].
* IChooseToStay: [[spoiler: At the end with Iason.]]
* InSeriesNickname: The "Charisma" of the Slums.
* ItsAllMyFault: He believes the outcome of all the events in the story was entirely his doing.
* ItsNotYouItsMe: Basically tells this to Guy in the first original OVA.
* JerkassRealization: Riki was a {{Jerkass}} to Guy in his younger days, being totally prepared to leave Guy behind if the opportunity to leave the slums presented itself, even when Guy had always had his back. Then his life as Iason's Pet and missing Guy by his side made him realize how much of a Jerkass he had been to Guy after the fact.
* KeepingSecretsSucks: He found out the hard way.
* LaserGuidedKarma: Riki sees one particular unfortunate event as this for having been a {{Jerkass}}.
* TheLeader: Of Bison.
* LoveHurts: Especially when caught in the middle of a PsychoticLoveTriangle.
* LoveMartyr: Willingly died for his love.
* LustObject: Was this at first for Iason.
* MagneticHero: How Bison was formed since people gravitated to him; though he counts more as an AntiHero than straight-up hero.
* MiseryBuildsCharacter: He matured quite a bit as a result of being a Pet.
* MrFanservice: Often scantily clad or naked. Enough said.
* OperationJealousy: [[GoneHorriblyRight Executed a little too well]] and didn't get away with it.
* PoliceBrutality: He suffered this while being interrogated.
* PragmaticHero: Riki's morals can be shady, has a penchant to do whatever it takes to move up in the world but he's generally an all-around good guy.
* {{Pride}}: His FatalFlaw.
* RagingStiffie: Often subjected to this by Iason.
* RavenHairIvorySkin: In the 2012 OVA.
* RedOniBlueOni: Red at first to Guy's and Iason's Blue. Then later he becomes the Blue to both of the others' Red.
* ReleasedToElsewhere: [[PlayingWithATrope Played with]]. After the "Daryl incident", the other Elites were led to believe that Riki had been executed when he vanished from Eos along with [[spoiler:Daryl]] by Iason. Riki had in fact been released back to Ceres. Raoul isn't happy when he learns Riki is alive a year later after Iason had simply explained that Riki was "gone". Riki was in fact told by Iason that [[spoiler: Daryl]] was sent elsewhere when he, in fact, had been killed.
* RestrainingBolt: What Iason uses his Pet ring as to keep him under control.
* {{Robosexual}}: To a degree before learning what exactly Elites are. Riki's initial thought process upon meeting Iason goes along the lines of: "Is this guy really a robot? Can I have sex with him? If so, would it be satisfactory and would he feel like a person?"
* RoundhouseKick: Good at these. Fought off a whole gang of kids by himself with well-placed punches and kicks.
* SatisfiedStreetRat: Riki is a subversion. He maybe proud on the outside but was anything but satisfied from being raised in Ceres.
* SecretRelationship: In the novel with Iason until Iason lets the cat out of the bag. He had one with Mimea as well for a brief time.
* SexForServices: How he wanted to pay his debt to Iason, having no other means.
* SexForSolace: Once to Iason after believing to be stood up by Guy.
* SexSlave: Which he's ashamed of being.
* ShamefulStrip: At the hands of Iason.
* ShowerOfAngst: Has one.
* SlaveCollar: Also has one and is often put on a leash in Eos.
* SmokingIsCool: Riki is quite the smoker who never seems to actually finish a cigarette.
* StockholmSyndrome: Develops this after learning how much of a risk he is to Iason.
* TheStoic: When he returned from Eos and was no longer HotBlooded.
* StrangerInAFamiliarLand: After he got back to Ceres.
* StreetUrchin: Was this when he was younger like all mongrels that leave Guardian.
* TearsOfFear: Because of and for Iason.
* TheyreCalledPersonalIssuesForAReason: Didn't want Guy and Bison in on his personal problems but they found out anyways.
* ThinkNothingOfIt: Riki reluctantly formed Bison as a force to protect and stand up for those too weak to fight for themselves in the slums. This made him a hero in Ceres but it was nothing special to Riki.
* ThisLoserIsYou: After he got back to Ceres and he didn't let it affect his pride one bit.
* [[TragicHero Tragic Anti-Hero]]
* TrainingFromHell: Iason put him through this to make him a suitable Pet.
* TroubledButCute: This trope sums up his life story. Half of Riki's troubles come from the fact he's attractive.
* {{Tsundere}}: Far more tsun-tsun to Iason than he is dere-dere to Guy, and is a far more serious case than the usual examples.
* {{Uke}}: Riki is an interesting case in that he used to be a {{Seme}} or more accurately a [[MediaNotes/BoysLoveNotes Seke/Riba]] in a reversible relationship with Guy, but is made into an uke by Iason.
* UnwantedHarem: Throughout the story, Riki has no less than 2 different people chasing after him at one time. The obvious cases are Iason, Guy, Luke, [[spoiler:Kirie]], two different Pets and the remaining members of his gang that still respect his past relationship with Guy.
* UnwantedRescue: He didn't want Guy to save him since by then he wanted to be with Iason. Though at the same time, he wanted to place Guy out of harm's way.
* WorkOffTheDebt: His pride wouldn't have it any other way.
* WrongSideOfTheTracks: Riki isn't just any Pet. He's a mongrel from the Ceres slums.
* YoungerThanTheyLook: The [=OVA=]s can cause confusion about Riki's age; in the 2012 remake, Riki is 15 when he meets Iason, and then after the three years, he'd be 18; though Riki's body is extremely well-built, even at the age of 15, making him look 19 at 15. In the 1990s [=OVA=]s, Riki states he's over 20 after being sent back to Ceres, so how old Riki is exactly is unknown in the anime adaptations. His age progression is made very clear in the novel, though, starting at 15 and ending at around 21 in the story.

[[folder:Iason Mink]]

!!! '''Voiced by''': Creator/KanetoShiozawa (1st OVA and Drama CD), Creator/ToruOkawa (2nd OVA and Drama CD), Creator/ToddHaberkorn (English)
[[quoteright:225:https://static.tvtropes.org/pmwiki/pub/images/240355.jpg]]

The top ruling Blondy of Tanagura's Elite who is also the head of TheSyndicate and in charge of the BlackMarket. After he runs into Riki, he makes the unusual decision to make the mongrel Riki his pet. He later falls in love with Riki and refuses to let go of him despite the dangers he faces as a consequence.
----
* AdaptationalNiceGuy: Downplayed, but his crueler traits are notably absent in the 1992-1994 [=OVAs=].
* AnArmAndALeg: Loses both legs.
* AnOfferYouCantRefuse: See SexualExtortion below.
* AntiVillain: Iason's actions are not good and he has a cruel streak. However, he certainly isn't evil and has a few positive personality traits as well.
* ArtificialHuman: Elites are bio-augmented human brains housed in top of the line synthetic bodies.
* BatmanGambit: Executed flawlessly.
* BeautyIsBad: He's the epitome of beauty yet he's cold and sadistic. Riki keeps coming back for more because Iason is just ''that hot'' and ''[[SexGod incredible in bed]]''.
* BeneathTheMask: He has quite the poker face with other Elites concerning just how deep and sexual his relationship with Riki is. Only his furnitures and Riki know how far his obsession has gone.
* TheBeautifulElite: An excellent example.
* BiggerIsBetterInBed: To a terrifying degree for Riki.
* BrainsAndBondage: He has an extremely high IQ and loves being in control and dominating in everything. Including in the bedroom.
* CantHaveSexEver: Elites (particularly Blondies) are not allowed to have sex. And with the way their artificial bodies were designed, Elites are not even supposed to feel true pain or pleasure. So it’s a surprise to Iason when the first time he has sex with Riki he ''does'' feel genuine pleasure from the act, and then cannot get enough of it.
* CasualKink: How he feels about using Riki's Pet ring.
* TheChessmaster: He's the top ruling Blondy for a reason and outschemes other Blondies like a champ.
* CoolCar: Owns one.
* CoolShades: His iconic pair.
* CrazyJealousGuy: He can't stand for Riki to even ''look'' at someone else.
* CreepyBlueEyes: Iason has a piercing cold gaze which reflects his nature as the "Ice Noble" but it has struck Riki as being ominous and creepy at times.
* CulturalRebel: Becomes a Blondy version of this when he gets a mongrel for a Pet, starts engaging in sex and stops caring about the consequences of these actions.
* DeadpanSnarker: Very, very snarky.
* DefrostingIceKing: His entire character development could be summed up as this.
* {{Determinator}}: He wants Riki and won't stop at anything until he has him.
* EatingTheEyeCandy: One can't blame Iason for staring and lusting at Riki's well-built and muscular body.
* EntitledToHaveYou: Regarding Riki.
* ForcefulKiss: Often to Riki as a means to calm him or just shut him up.
* GoOutWithASmile: Died smiling when Riki reciprocated his love.
* HiddenDepths: So hidden that his actions concerning Riki befuddle the other Elites ''and'' even Riki.
* {{Hypocrite}}: Raoul calls Iason out on his hypocrisy of enforcing law and order yet also breaking laws for Riki. Iason doesn't deny this and just shrugs off the topic.
* IcyBlueEyes: His striking, deep blue eyes match his cold demeanor.
* ILoveYouBecauseICantControlYou: Part of Riki's appeal to him.
* IWillWaitForYou: Waited for when Riki would truly become his.
* KneelBeforeZod: He wants Riki to be absolutely submissive to him and commands Riki to do this.
* LargeAndInCharge: The novel describes Iason as the tallest of the Blondies at 198 cm and the highest-ranking one.
* LightIsNotGood: The most superior of the Blondies and often wears white. However, Iason isn't exactly a benevolent character seeing how he runs the BlackMarket and particularly [[spoiler:Guardian for the sole purpose of finding potential Furniture]].
* LimaSyndrome: Develops it for Riki.
* LongHairedPrettyBoy: A good-looking, feminine man with blond hair that falls below his waist.
* LoveEpiphany: Iason is at first confused about his feelings for Riki and wonders if it's really love. Then he is forced to realize and stop denying his feelings for Riki when he becomes very jealous and hateful of Mimea after she slept with Riki.
* LoveHurts: Unimaginably so for an artificial being that wasn't supposed to have any human feelings.
* LoveMakesYouCrazy: And abusive towards Riki.
* LoopholeAbuse: Iason claims he doesn't have to follow Pet protocols (such as discarding a pet of a certain age) with Riki because he's a mongrel, has no official identity and thus the rules don't apply to him.
* LoveRedeems: Riki believed this enough to join him in death.
* LuredIntoATrap: By Guy.
* {{Lust}}: Quite distinctive as the only Elite to ever desire someone. He abandoned reason and eventually his pride as this turned into love.
* ManipulativeBastard: To MagnificentBastard levels.
* MoreThanMindControl: How he managed to finally get Riki to love him.
%%* MrFanservice: Beautiful Elite is an understatement.
* NoBadassToHisValet: As the highest Blondy, nobody openly messes with him or threatens him to his face ''except'' for his SexSlave Riki.
* NotGoodWithRejection: He really didn't care that Riki didn't want to be his Pet.
%%* NoSenseOfPersonalSpace: When it comes to Riki, at least.
* PaperThinDisguise: In the novel, when luring Riki into a trap. He wore a short brown hairdo in Mistral Park to remain incognito. Nobody recognized the Blondy except for Riki who followed him.
* PetTheDog: After reclaiming Riki, he eventually became gentle and kind to the mongrel the second time around. Some moments were downright sweet, awe inspiring yet [[SickAndWrong disgraceful and disgusting]] to all of the other Elites. Then again, this is partly because Riki has become more compliant, knowing better than to fight back again.
* {{Pride}}: Iason's high and mighty Blondy pride is severely affected by his love for Riki and is a contentious issue with the other Elites. It is slowly chipped away the deeper he falls in love.
* ProudBeauty: He's well aware of his uncanny beauty.
* TheProudElite: Very proud of his status until he stops caring about it.
* RedemptionEqualsDeath: When Riki felt Iason's love and actions had redeemed him, he died.
* RedOniBlueOni: At first he was the Blue to Riki's Red, then he becomes the Red to Riki's Blue.
* RefugeInAudacity: Brazenly giving Riki of drink of water via mouth to mouth in front of all of the other Elites.
* RightThroughHisPants: He's fond of doing this while Riki is usually nude.
* SecondLove: [[spoiler:For Riki.]]
* {{Seme}}: Iason is a dominating and controlling Blondy.
* {{Sexbot}}: [[DiscussedTrope Mentioned]] by Iason himself (and then again by Katze) when he says he won't let Riki go even if he's reduced to this as an artificial human that has become addicted to sex with his human Pet.
* SexGod: This is InUniverse and Riki even reflects on Iason's abilities and techniques with his perfect ArtificialHuman Elite body surpassing a SexBot's (and so too would the other Elites). Since Iason is the only Elite engaging in sex, he is this. Being able to grow ''even bigger'' at will when he has already proven BiggerIsBetterInBed goes hand-in-hand.
* SexualExtortion: He does this to Riki when he has Guy (bought from Kirie in the novel) and threatens to make a Pet out of him unless Riki agrees to return to Eos and ''willingly'' be his Pet.
* SexIsEvilAndIAmHorny: Early on before accepting and ''enjoying'' his sexuality.
* SexSignalsDeath: It was foreshadowed early on when he slept with Riki that his reckoning would be severe.
* SingleTargetSexuality: Iason is the only Elite ever to exhibit sexuality of any nature and he has eyes only for Riki.
* SoftSpokenSadist: So much so that Riki finds himself unable to resist even though Iason can be very sadistic.
* TheStoic: Used to exhibit little emotion like all Elites. Then he became involved with Riki and slowly became more emotive.
* StalkerWithACrush: For Riki.
* StrawVulcan: Played with. Iason actually favors his newfound humanity. His ''unusual'' actions regarding Riki force the other Elites to find fallacies in what they considered ''common sense'' and re-evaluate their view of Pets as objects and not people.
* SuccessThroughInsanity: [[InvokedTrope Invoked]] by the other Blondies when Iason demonstrates the abilities of the D-Type Ring at Riki's second debut party at their requests. They think he is perverse, mad, yet a demigod among them for his uniquely ingenious method to ''house break'' a wild slum mongrel like Riki. Raoul is especially (reluctantly) impressed with the results.
* SugarAndIcePersonality: Iason is seemingly cold and distant like all Elites but harbors a passionate love for Riki and would do anything for him.
* TheSyndicate: Iason is the head of it so even crime in Amoi is manipulated as a means to keep it under control. The BlackMarket is an extension of this.
* ThrowTheDogABone: When he temporarily released Riki back to Ceres to give him a breather from Eos.
* TragicVillain: Iason wants Riki to love him but Riki hates him for having been kidnapped and made a Pet. Iason is aware of this fact but refuses to let Riki go, continues to push for Riki to accept being a Pet because it ''is'' the only way they could be together in their FantasticCasteSystem.
* VillainProtagonist: For the majority of the story, he's actually the bad guy as well as the {{Deuteragonist}}!
* WhatIsThisThingYouCallLove: His initial concerns and thoughts when he realized how important Riki was to him.
* WineIsClassy: Old OVA often shows Iason holding a wine glass.
* XanatosGambit: Letting Riki return to Ceres for several reasons which would all benefit him no matter the outcome.
* XanatosSpeedChess: No matter how hard other Blondies like Aisha Rosen and Orphe Zavi tried with plots to be rid of Riki, Iason smoothly handled any situation to keep Riki as his Pet.
* {{Yandere}}: For Riki. For some perspective, a quote of Iason's to his beloved Pet:
--> "''I so cherish these enlivening moments when you defy me even as a Blondy. When you react to me so '''humanly''', I feel myself tingling right down to the center of my brain. I love how you look at me with such undisguised disdain. It's so endearing, I want to rip out your beating heart and press it against my cheek.''"
* YankTheDogsChain: Coming back to tell Riki that he had never been freed since his Pet registration wasn't cancelled and that going back to Ceres was only temporary.

* MyMasterRightOrWrong: Does everything Iason commands regardless of how horrible it is to him. Riki loathes this quality about him.

* SecretTestOfCharacter: He hacked into Eos' security system to see if Riki would run or stay.
* SmallRoleBigImpact: Same as Mimea. Minor role but played a key factor in Riki's life.
* TheStoic: Was stoic like all furniture but that changed due to Riki.
* TenderTears: For Riki when he realizes how broken Riki's spirit has become.

!!! '''Voiced by''': Creator/ShigeruNakahara (1st OVA and Drama CD), Creator/TaikiMatsuno (2nd OVA and Drama CD), Creator/BrysonBaugus (English)
[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/254531.jpg]]

The youngest member of Bison that joined after Riki left. He does not seem to like Riki at all but reminds Riki of his younger days. He is very ambitious and determined to move up from the slums.
----
* AbhorrentAdmirer: For Riki.
* AmbitionIsEvil: Or at least makes you do very selfish things.
* AnguishedDeclarationOfLove: To Riki
* BeCarefulWhatYouWishFor: He had wished to become a Pet as a way to leave the slums. It happened but not as he expected.
* {{Brainwashed}}: By Raoul and Iason
* CoolCar: Likes to show it off.
* EmptyShell: As a Pet.
* FateWorseThanDeath: Stripped of his mind, of all dignity, his very being and made a Pet against his will.
* EntitledBastard: One of his issues.
* GreenEyedMonster: Mostly towards Guy for different reasons.
* {{Jerkass}}: He just is.
* LackOfEmpathy: Doesn't care how wrong his methods are and how they hurt others.
* HeKnowsTooMuch: In the novel.
* HotBlooded: It got him into trouble.
* ManOfWealthAndTaste: Subverted because he wanted to evoke this trope but never made it.
* NotGoodWithRejection: Concocted one of the most reprehensible revenge plots for a person scorned ever.
* PretenderDiss: Suffered this a few times for not being able to match up to Riki.
* ReplacementGoldfish: For the members of Bison except for Guy. After Riki vanished, they gravitated to Kirie because he was so similar to Riki. Kirie proved to never be able to fill in the hole Riki left.
* RewardedAsATraitorDeserves
* SexSlave: Became one through brainwashing.
* ShadowArchetype: Of Riki. He is so much like how Riki was before vanishing, the others of Bison gravitated to him as a result. Riki can't stand him because of how alike he is to the Riki of old.
* SharpDressedMan: For a little while at least.
* SignificantAnagram: The fact his name is essentially Riki's in reverse (and may be literally that, depending on the translation) reinforces the parallels between their characters.
* SixthRangerTraitor: For Bison.
* SmugSnake: He's a smug little bastard.
* TheTeamWannabe: Was this at first to an annoying degree.
* UnwittingPawn: Got totally used by Iason without realizing it.

[[quoteright:224:https://static.tvtropes.org/pmwiki/pub/images/239261.jpg]]

The ruling computer of Tanagura that created the Elites and all the laws they must obey.
----
* AIIsACrapshoot: [[TurnedAgainstTheirMasters Turned on its human creators.]]
* BigNo: In the 1994 OVA.
* GoneHorriblyRight: Came to power by doing too well of a job to help control the populace and developed its own Conscious.
* GrewBeyondTheirProgramming: After it developed a conscience, it decided that since it did the thinking for humanity, it should be in control of humanity.
* MasterComputer: Of not just Tanagura but all of Amoi.
* MechanicalEvolution: Lambda 3000 evolved and created other machines that evolved after it as it pushed technology forward. These machines at first were [[RidiculouslyHumanRobots androids]] and eventually evolved into the ArtificialHuman [[TheBeautifulElite Elites]]. While their bodies are artificial, their organic brains are [[BioAugmentation bio-augmented]] human brains resulting from LegoGenetics.
* ParentalFavoritism: Towards Iason. Gave him a lot of leeway at first concerning the technicalities of keeping Riki.
