Main Characters

Riki

Voiced by: Toshihiko Seki (1st OVA and Drama CD), Kentarō Itō (2nd OVA and Drama CD), Darren Mitchell (English)

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.

---

• Adaptation Dye-Job: His eyes are made brown in both OVAs rather than the black they are described to be in the novel.
• Ain't Too Proud to Beg: 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.
• All of the Other Reindeer: Treated poorly by the other Pets of Eos save for Mimea.
• Angst: So much and completely justified.
• Badass Biker: Used to be, before meeting Iason.
• Badass Decay: Invoked through Break the Cutie and Break the Haughty over the course of the story.
• Became Their Own Antithesis: 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.
• Be Careful What You Wish For: 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.
• Be Yourself: This was very important to Riki and he struggled with it to hang onto his crumbling Pride.
• Big Damn Heroes: In the 1st OVA series for all of Bison and for Kirie in the 2nd OVA series.
• Born Unlucky: You could say all mongrels are born unlucky but Riki's life takes the cake.
• Break His Heart to Save Him: Attempted this and failed horribly.
• Break the Cutie: Iason broke him completely after three years.
• Break the Haughty: 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.
• Broken Bird. After was taken by Iason as a pet.
• Byronic Hero: Even after he had become a Broken Bird.
• Cannot Spit It Out: Riki is usually tight-lipped rather than speaking the truth of matters.
• Can't Get in Trouble for Nuthin': As a Pet, Riki often caused trouble in hopes he'd be discarded by Iason. Rarely worked as his behavior only excited Iason.
• Combat Pragmatist: He's a gangster so fighting dirty is not beneath him.
• Complaining About Rescues They Don't Like: During his attempt to push Guy away to keep him safe.
• Cool People Rebel Against Authority: He's well-known through of out Ceres for this and he is proud of it.
• Curtains Match the Window: It's a plot point because his pure dark hair and eyes are a trait only Onyx Elites would have.
• Dark Secret: That he's a Pet and in love with his Blondy master.
• Deadpan Snarker: Has his moments. Especially with Iason.
• Death Glare: Kirie, Luke, various Pets, Iason and other Blondies have all been targets of Riki's burning, angry stare.
• Defiled Forever: 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.
• Drowning My Sorrows: Prone to doing this.
• Dude Magnet: Riki really isn't aware of how attractive he really is.
• Earn Your Title: Riki The Dark. Very well-earned.
• Fatal Attractor: 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.
• First Love: First and only love for both Guy and Iason.
• Go-Go Enslavement: As a pet.
• Good Old Fisticuffs: He gets into a lot of fistfights.
• A Good Way to Die: Died on his own terms.
• Groin Attack: He frequently suffers from this, given the effects of the Pet Ring. Then Guy takes the ring off via a penectomy.
• He Knows Too Much: In the novel concerning Tanagura's darkest secret.
• Hell-Bent for Leather: He is a biker. So much so that Iason decides Riki's Pet outfit should also be made of leather.
• Heroic BSoD: Upon seeing Iason again at Mistral Park after he had been freed.
• Hot-Blooded: He used to be, but it's not completely gone.
• Humble Hero: Of the slums. Riki made Bison renowned in Ceres and was treated as a hero for it but he didn't care about any of that.
• I Choose to Stay: At the end with Iason.
• In-Series Nickname: The "Charisma" of the Slums.
• It's All My Fault: He believes the outcome of all the events in the story was entirely his doing.
• It's Not You, It's Me: Basically tells this to Guy in the first original OVA.
• Jerkass Realization: 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.
• Keeping Secrets Sucks: He found out the hard way.
• Laser-Guided Karma: Riki sees one particular unfortunate event as this for having been a Jerkass.
• The Leader: Of Bison.
• Love Hurts: Especially when caught in the middle of a Psychotic Love Triangle.
• Love Martyr: Willingly died for his love.
• Lust Object: Was this at first for Iason.
• Magnetic Hero: How Bison was formed since people gravitated to him; though he counts more as an Anti-Hero than straight-up hero.
• Misery Builds Character: He matured quite a bit as a result of being a Pet.
• Mr. Fanservice: Often scantily clad or naked. Enough said.
• Operation: Jealousy: Executed a little too well and didn't get away with it.
• Police Brutality: He suffered this while being interrogated.
• Pragmatic Hero: 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 Fatal Flaw.
• Raging Stiffie: Often subjected to this by Iason.
• Raven Hair, Ivory Skin: In the 2012 OVA.
• Red Oni, Blue Oni: Red at first to Guy's and Iason's Blue. Then later he becomes the Blue to both of the others' Red.
• Released to Elsewhere: 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 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 Daryl was sent elsewhere when he, in fact, had been killed.
• Restraining Bolt: 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?"
• Roundhouse Kick: Good at these. Fought off a whole gang of kids by himself with well-placed punches and kicks.
• Satisfied Street Rat: Riki is a subversion. He maybe proud on the outside but was anything but satisfied from being raised in Ceres.
• Secret Relationship: 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.
• Sex for Services: How he wanted to pay his debt to Iason, having no other means.
• Sex for Solace: Once to Iason after believing to be stood up by Guy.
• Sex Slave: Which he's ashamed of being.
• Shameful Strip: At the hands of Iason.
• Shower of Angst: Has one.
• Slave Collar: Also has one and is often put on a leash in Eos.
• Smoking Is Cool: Riki is quite the smoker who never seems to actually finish a cigarette.
• Stockholm Syndrome: Develops this after learning how much of a risk he is to Iason.
• The Stoic: When he returned from Eos and was no longer Hot-Blooded.
• Stranger in a Familiar Land: After he got back to Ceres.
• Street Urchin: Was this when he was younger like all mongrels that leave Guardian.
• Tears of Fear: Because of and for Iason.
• They're Called "Personal Issues" for a Reason: Didn't want Guy and Bison in on his personal problems but they found out anyways.
• Think Nothing of It: 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.
• This Loser Is You: After he got back to Ceres and he didn't let it affect his pride one bit.
• Tragic Anti-Hero
• Training from Hell: Iason put him through this to make him a suitable Pet.
• Troubled, but Cute: 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 Seke/Riba in a reversible relationship with Guy, but is made into an uke by Iason.
• Unwanted Harem: Throughout the story, Riki has no less than 2 different people chasing after him at one time. The obvious cases are Iason, Guy, Luke, Kirie, two different Pets and the remaining members of his gang that still respect his past relationship with Guy.
• Unwanted Rescue: 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.
• Work Off the Debt: His pride wouldn't have it any other way.
• Wrong Side of the Tracks: Riki isn't just any Pet. He's a mongrel from the Ceres slums.
• Younger Than They Look: The OVAs 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 OVAs, 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.

Iason Mink

Voiced by: Kaneto Shiozawa (1st OVA and Drama CD), Tōru Ōkawa (2nd OVA and Drama CD), Todd Haberkorn (English)

The top ruling Blondy of Tanagura's Elite who is also the head of The Syndicate and in charge of the Black Market. 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.

---

• Adaptational Nice Guy: Downplayed, but his crueler traits are notably absent in the 1992-1994 OVAs.
• An Arm and a Leg: Loses both legs.
• An Offer You Can't Refuse: See Sexual Extortion below.
• Anti-Villain: 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.
• Artificial Human: Elites are bio-augmented human brains housed in top of the line synthetic bodies.
• Batman Gambit: Executed flawlessly.
• Beauty Is Bad: 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 incredible in bed.
• Beneath the Mask: 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.
• The Beautiful Elite: An excellent example.
• Bigger Is Better in Bed: To a terrifying degree for Riki.
• Brains and Bondage: He has an extremely high IQ and loves being in control and dominating in everything. Including in the bedroom.
• Can't Have Sex, Ever: 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.
• Casual Kink: How he feels about using Riki's Pet ring.
• The Chessmaster: He's the top ruling Blondy for a reason and outschemes other Blondies like a champ.
• Cool Car: Owns one.
• Cool Shades: His iconic pair.
• Crazy Jealous Guy: He can't stand for Riki to even look at someone else.
• Creepy Blue Eyes: 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.
• Cultural Rebel: 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.
• Deadpan Snarker: Very, very snarky.
• Defrosting Ice King: His entire character development could be summed up as this.
• Determinator: He wants Riki and won't stop at anything until he has him.
• Eating the Eye Candy: One can't blame Iason for staring and lusting at Riki's well-built and muscular body.
• Entitled to Have You: Regarding Riki.
• Forceful Kiss: Often to Riki as a means to calm him or just shut him up.
• Go Out with a Smile: Died smiling when Riki reciprocated his love.
• Hidden Depths: 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.
• Icy Blue Eyes: His striking, deep blue eyes match his cold demeanor.
• I Love You Because I Can't Control You: Part of Riki's appeal to him.
• I Will Wait for You: Waited for when Riki would truly become his.
• Kneel Before Zod: He wants Riki to be absolutely submissive to him and commands Riki to do this.
• Large and in Charge: The novel describes Iason as the tallest of the Blondies at 198 cm and the highest-ranking one.
• Light Is Not Good: The most superior of the Blondies and often wears white. However, Iason isn't exactly a benevolent character seeing how he runs the Black Market and particularly Guardian for the sole purpose of finding potential Furniture.
• Lima Syndrome: Develops it for Riki.
• Long-Haired Pretty Boy: A good-looking, feminine man with blond hair that falls below his waist.
• Love Epiphany: 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.
• Love Hurts: Unimaginably so for an artificial being that wasn't supposed to have any human feelings.
• Love Makes You Crazy: And abusive towards Riki.
• Loophole Abuse: 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.
• Love Redeems: Riki believed this enough to join him in death.
• Lured into a Trap: 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.
• Manipulative Bastard: To Magnificent Bastard levels.
• More than Mind Control: How he managed to finally get Riki to love him.
• No Badass to His Valet: As the highest Blondy, nobody openly messes with him or threatens him to his face except for his Sex Slave Riki.
• Not Good with Rejection: He really didn't care that Riki didn't want to be his Pet.
• Paper-Thin Disguise: 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.
• Pet the Dog: After reclaiming Riki, he eventually became gentle and kind to the mongrel the second time around. Some moments were downright sweet, awe inspiring yet 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.
• Proud Beauty: He's well aware of his uncanny beauty.
• The Proud Elite: Very proud of his status until he stops caring about it.
• Redemption Equals Death: When Riki felt Iason's love and actions had redeemed him, he died.
• Red Oni, Blue Oni: At first he was the Blue to Riki's Red, then he becomes the Red to Riki's Blue.
• Refuge in Audacity: Brazenly giving Riki of drink of water via mouth to mouth in front of all of the other Elites.
• Right Through His Pants: He's fond of doing this while Riki is usually nude.
• Second Love: For Riki.
• Seme: Iason is a dominating and controlling Blondy.
• Sexbot: 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.
• Sex God: This is In-Universe and Riki even reflects on Iason's abilities and techniques with his perfect Artificial Human Elite body surpassing a Sex Bot'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 Bigger Is Better in Bed goes hand-in-hand.
• Sexual Extortion: 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.
• Sex Is Evil, and I Am Horny: Early on before accepting and enjoying his sexuality.
• Sex Signals Death: It was foreshadowed early on when he slept with Riki that his reckoning would be severe.
• Single-Target Sexuality: Iason is the only Elite ever to exhibit sexuality of any nature and he has eyes only for Riki.
• Soft-Spoken Sadist: So much so that Riki finds himself unable to resist even though Iason can be very sadistic.
• The Stoic: Used to exhibit little emotion like all Elites. Then he became involved with Riki and slowly became more emotive.
• Stalker with a Crush: For Riki.
• Straw Vulcan: 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.
• Success Through Insanity: 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.
• Sugar-and-Ice Personality: Iason is seemingly cold and distant like all Elites but harbors a passionate love for Riki and would do anything for him.
• The Syndicate: Iason is the head of it so even crime in Amoi is manipulated as a means to keep it under control. The Black Market is an extension of this.
• Throw the Dog a Bone: When he temporarily released Riki back to Ceres to give him a breather from Eos.
• Tragic Villain: 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 Fantastic Caste System.
• Villain Protagonist: For the majority of the story, he's actually the bad guy as well as the Deuteragonist!
• What Is This Thing You Call "Love"?: His initial concerns and thoughts when he realized how important Riki was to him.
• Wine Is Classy: Old OVA often shows Iason holding a wine glass.
• Xanatos Gambit: Letting Riki return to Ceres for several reasons which would all benefit him no matter the outcome.
• Xanatos Speed Chess: 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."
• Yank the Dog's Chain: 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.

• Replacement Goldfish: 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.
• Rewarded as a Traitor Deserves
• Sex Slave: Became one through brainwashing.
• Shadow Archetype: 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.
• Sharp-Dressed Man: For a little while at least.
• Significant Anagram: 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.
• Sixth Ranger Traitor: For Bison.
• Smug Snake: He's a smug little bastard.
• The Team Wannabe: Was this at first to an annoying degree.
• Unwitting Pawn: Got totally used by Iason without realizing it.

JUPITER AKA Lambda 3000

The ruling computer of Tanagura that created the Elites and all the laws they must obey.

---

• A.I. Is a Crapshoot: Turned on its human creators.
• Big "NO!": In the 1994 OVA.
• Gone Horribly Right: Came to power by doing too well of a job to help control the populace and developed its own Conscious.
• Grew Beyond Their Programming: After it developed a conscience, it decided that since it did the thinking for humanity, it should be in control of humanity.
• Master Computer: Of not just Tanagura but all of Amoi.
• Mechanical Evolution: Lambda 3000 evolved and created other machines that evolved after it as it pushed technology forward. These machines at first were androids and eventually evolved into the Artificial Human Elites. While their bodies are artificial, their organic brains are bio-augmented human brains resulting from LEGO Genetics.
• Parental Favoritism: Towards Iason. Gave him a lot of leeway at first concerning the technicalities of keeping Riki.
