Voiced by: Yuji Takada (JP), Christopher Sabat (EN), Adolfo Nittoli (Latin-American Spanish)An Intrepid Reporter who used to be a war photographer and is renowned for the quality of his shoots. An interesting byproduct of his job is that he is sexually aroused by taking his photos. Despite being jaded and cynical, he is still passionate about his job and works for a regular magazine. It's during an infiltration mission that he sets foot in the Roppongi Club, a depraved secret society of wealthy hedonists whose primary goal is to indulge in their basest desires.He ends up captured and is given a Spit-Trail Kiss by a hypnotized young girl named Kagura Tennozou, the club's "Goddess" whose ethereal beauty captivates him instantly. He was supposed to die, but the kiss triggered the "Euphoria Factor" in him instead. Apparently a latent gene that only people known as "Euphorics" have, this virus know grants him the power to make the targets of his photo shoots explode and makes him practically invulnerable to conventional injury. Using his newfound abilities, he escapes, taking Kagura as a hostage.Both grow quickly close as Kagura comes to her senses. She realizes just what had been done to her and breaks down in tears, begging her abductor to take her away with him, and considering how fucked up her life has been until then, she's got all the reason in the world to wish for that. Saiga decides to free Kagura from the Roppongi club and her unkind mother's clutches.
- Action Survivor: He was a veteran war photographer before the series and he fits the trope in both appearance and methods.
- Anti-Hero: He's a a bit of a prick, but underneath that he's a genuinely good man.
- Bad Powers, Good People: Despite being gifted with powers that make him a truly lethal assassin, he's actually one of the few good and decent people in the series.
- Blessed with Suck: His super-powers mean he can't ever take a photo without destroying whatever he's targeting. Which is particularly problematic given that's what he does for a living. Also, overusing his powers is killing his eyes and will eventually send him blind. By the series' end, his eyes have exploded.
- Celibate Hero: Well, he tries. Ginza has other ideas. In fact, Saiga just can't seem to escape women in general.
- Deadpan Snarker: Saiga's sense of humour is very dry, to say the least.
- Empowered Badass Normal: Saiga was an accomplished war photographer and accustomed to violence before becoming a euphoric...
- Even the Guys Want Him: He's long since gained attention from Bob, and some would argue Joe as well.
- Intrepid Reporter: He used to be a war photographer, but since quitting that, he's engaged himself in this as a job.
- Jerk with a Heart of Gold: A huge heart of gold indeed. The jerk parts are relatively minor, but more prominent because he doesn't interact with many characters that aren't Kagura.
- Knight In Shining Armour: To Kagura.
- Knight in Sour Armour: Saiga knows the world is corrupt and one man can't change it all. That doesn't stop him from being a good person.
- Mr. Fanservice: During the spa segment and the church episode.
- Nigh-Invulnerability: Only decapitation can kill him, like all Euphorics.
- Nightmare Fetishist: Not even he realizes his fetish until he gets his powers. And Ginza does mention once that he needs a camera to get aroused.
- Papa Wolf: The man will protect Kagura.
- Power Incontinence: Strangely, all other Euphorics in the series have a level of control over their powers and can avoid triggering them, they just don't. Saiga however, can never take another photo without destroying the subject.
- Red Right Eye: Subverted. His eye becomes red upon using his power but he isn't evil per se.
- Shirtless Scene: The guy is so damn ripped it's no wonder Ginza lusts after him.
- Tall, Dark and Handsome: Probably the best example in the show.
Voiced by: Kei Shindou (JP), Monica Rial (EN), Maythe Guedes (Latin-American Spanish)A sweet, demure and innocent young girl who lives sheltered in a high skyscraper in Tokyo. Abused and mistreated by her horrible mother, she still endures it quietly, hoping that one day her courage may pay off and that her mother might grow to genuinely love her. Besides this, she is unwittingly the object of worship of the depraved secret society of Roppongi and is known as "The Goddess".When Saiga abducts her to save himself, she eventually realizes how she's been manipulated and used by her entourage and begs Saiga to take her away with him. Captivated by the purity of Kagura, he complies.Kagura's growth has been artificially stunted so that she may not lose her catalytic powers that trigger the Euphoria virus in the carriers of the gene. Since she is under constant medication, she also runs a risk of dying if she doesn't go through intensive rehab due to how intoxicated her body is with the drugs she was force-fed back in the days.
- Betty and Veronica: The Betty to Hibari's Veronica.
- Break the Cutie: Where do we begin? Her life is an absolute trainwreck. It likely starts well before the first episode, given what that one reveals about her in the first place.
- Distressed Damsel: She can't be blamed. Being 15, when Suitengu's men capture her or Ginza recovers her, she can't fight back all that well.
- Gilded Cage: Her home life in the beginning, and her capture later.
- Girl in the Tower: In the later episodes, after being recovered.
- Ill Girl: Her growth has been stunted, she's a living production factory for a lethal mutagen, and she has a brain tumor.
- The Ingenue: Her innocence is a large factor in making her a sympathetic character. She doesn't have much beyond it, but it's a wonder she has it, given her upbringing.
- MacGuffin Super Person: She houses the Euphoria Virus. The entire series is about rescuing her from her family.
- Magic Kiss: She can turn people's fantasies to real superpowers with her kiss.
- Magic Skirt: As much Male Gaze as the camera gives her, the Lolicon Fanservice is kept to a minimum and Panty Shots are (usually) averted.
- No Periods, Period: Played with. It is mentioned that she mustn't have her period else her powers might decrease... so she gets injected with a serum that stunts her growth.
- No Social Skills: She has no idea how to interact people once she's taken out of her tiny circle of rich adults. She gets felt up on a public shuttle and thinks he was tickling her.
- Orphan's Ordeal: Dead father. Dead mother too, late in the show.
- Precocious Crush: On Saiga. How precocious it really is isn't clear; she's well into puberty, but she's had her growth stunted and hasn't had her first period yet. Of course, no one would blame her if it wasn't.
- Spit-Trail Kiss: Her kiss implies to exchange saliva with her target. And that's never hot.
- Split Personality: As the Divine Goddess. She seems to be under some sort of hypnosis, and can't remember anything from when she's using the Goddess persona.
- Token Wholesome: Even as her Goddess persona, she appears with more decorum than the surrounding debauchery of the club. The contrast is most likely intentional.
- Troubled Fetal Position: In the Eye Catch, and every time she's confined.
- Your Days Are Numbered: Six months left to live, six months left to save her.
Voiced by: Takako Honda (JP), Clarine Harp (EN), Lilo Schmidt (Latin-American Spanish)A very proactive, sultry and shrewd Rabid Cop, Hibari is also Saiga's Stalker with a Crush who wants to have him for herself. Dressed in a red jumpsuit to highlight her knock-out body, she uses her golden-plated guns as a weapon and is far from being a by-the-book cop.Able to hold her own in a fight, she usually doesn't hesitate to use physical force to get the info she needs and isn't big on morality either. Seeing Kagura as a wedge between her and Saiga, she coldly gives her back to her horrible mother in exchange of having her way with an unconscious Tatsumi.Despite her initially obstructive behaviour, she eventually becomes intrigued with the Roppongi club and eventually understands that her enemy isn't necessarily the one she believes...
- Action Girl/Dark Action Girl: She's one of the most hostile characters in the show and pulls out guns where they really aren't necessary. She's really not a good person...
- Ambiguously Brown: She has white hair, but her skin is of a darker color than other characters in the show.
- Anti-Hero: Barely. A Nominal Hero at best.
- Betty and Veronica: The Veronica to Kagura's Betty.
- Biker Babe/Badass Biker: She rarely travels unless it's on her motorbike, which serves to highlight her fierce female cop attitude.
- Bling-Bling-BANG!: Her gold handguns.
- Catchphrase: "Self defense!"
- Cool Shades: Sometimes, sometimes not. She only takes them off when she gets into a serious matter.
- Double Standard: Rape, Female on Male: Saiga will never know what she did to him while he was unconscious.
- Dirty Cop/Rabid Cop: A Rare Female Example. She only enforces what she wants and even the lightest of her sins would get a cop fired in Real Life.
- Femme Fatale: She knows she's a hot piece of ass and she always uses it to her advantage.
- Guns Akimbo: Early on and near the end of the show.
- Heel Realization: She comes to realize how sick those she helped were, but not before raping Saiga
- Karma Houdini: Played with. She never shows the slightest bit of remorse for raping Saiga, and in fact, is rewarded with a happy ending. However, soon after said rape, she repeatedly becomes a Badass in Distress at the hands of some of the villains.
- Ms. Fanservice: She plays it up for all it's worth, but drops it in later episodes.
- Murder the Hypotenuse: She wishes to, and even tells that to Kagura with tears rolling down her cheeks but she doesn't proceed.
- Playing with Syringes: The last we see of her, she's with Dr. Ryougoku, playfully threatening a patient with a syringe.
- Stalker with a Crush: Towards Saiga. Unlike a lot of examples, it's played exactly for what it is.
- Tomboy: Can pull this off along with being a Femme Fatale.
- Visual Innuendo: Some of her... weapon handling, especially in the second OP. Though this is intentionally so; it's pretty obvious that, much as Saiga has a fetish for photography, she has a fetish for guns and shooting people.
Roppongi Club Higher-Ups
Voiced by: Toshiyuki Morikawa (JP), Chris Ayres (EN), Carmelo Fernández (Latin-American Spanish)A mysterious and enigmatic figure, known to the public only as the right hand man of Shinzen Tennozu. To the wealthy and powerful, he has another side, that of the master of the ultra-exclusive Roppongi Club, a black club where the elite can satisfy any fetish, perversion or delight they may have, no matter how depraved or the cost in human life.A Euphoric, Suitengu's power is to manipulate his own blood.

- Anti-Villain: Suitengu had a traumatic childhood, seeing his parents kill themselves, while his sister became a sex slave and he a child soldier, later forced to give her a mercy kill additionally, although he's ruthless about it, Suitengu seeks to better Japan by destroying the upper class that he suffered from first hand for so long.
- Appropriated Appellation: He got the name "Suitengu" from a name-plate tied to a sword he was wielding as one of the gangsters he saved asked for his name.
- The Bad Guy Wins: Though he dies, he pulls off his plan, wiping out the Japanese upper class in his club and triggering the collapse he wanted.

- Big Bad: The real one of the series.
- Bloody Murder: His main ability .
- Break the Cutie: His backstory involves his parents hanging themselves due to debt, abandoning him and his sister to be sold as a child soldier and a sex slave.

- Dragon-in-Chief: As well as a Dragon with an Agenda, to Shinzen.
- Empowered Badass Normal: Suitengu was a child soldier long before becoming the first euphoric.
- Even the Guys Want Him: Tsujido is so blatantly gay for him that it may as well be explicitly stated.
- The Extremist Was Right: Sure, him ultimately invoking Taking You with Me on an entire corrupt society was pretty freaking insane. However, they were still the collective Greater Scope Villains behind practically everything wrong in the series, and the epilogue does show everyone else's lives being much better as a result of his final actions.
- Four Eyes, Zero Soul: Soul and decent vision alike have long since left him.
- From Nobody to Nightmare: Once upon a time, he was an innocent kid with no real ambitions and definitely no evil ones. Then life happened and he's become one of the most powerful and ruthless men alive.
- Game Face: He doesn't show it to anyone unless he intends to kill them.
- Go Out with a Smile: How he dies.
- Gold Digger: A rare male example. It's not entirely about the gold, but it's important to him because of how much power it grants him in his scheme.
- Good Scars, Evil Scars: His birthmark.
- Good Smoking, Evil Smoking: Effeminately thin, long cigarettes rolled out of money.
- Hidden Agenda Villain: Shinzen and most of the other corrupt rich people he interacts with think he's in it for money and power, when in reality, he's a brutal Well-Intentioned Extremist who is plotting against them.

- Money to Burn: Those cigarettes? He rolls them himself. With million yen notes.
- Not So Stoic: He is sobbing when he is forced to mercy kill his beloved little sister. When he brutally beats a man to death for trying to prostitute his five year old daughter, he screams "You upper-crust vermin with your bloodstained money! You did this to me! You made me into this monster!
- Only a Flesh Wound: Shinzen shoots him in the leg for failing her, then demands he have sex with her in the pool. Justified, as he's a Euphoric with enhanced healing.
- Pet the Dog: Even while keeping Kagura confined, he shields her from her mother's abuse. When a club member is unable to pay his dues and his daughter naively tries to offer play money, Suitengu is touched and lets him off the hook. Turns out he was unwittingly reminded of his sister by that little girl.
- The Purge: His ultimate goal is to invoke a rare example where the recipients are all Asshole Victims — namely, the entire corrupt elite of Japan.
- Red Right Hand: His right hand bears a scar identical to the one Shinzen's sweetheart had, marking that arm as grafted onto him from that body.
- Scary Shiny Glasses: Quite often.
- Shirtless Scene: Near the end, he goes this along with One-Winged Angel.
- Tragic Villain/Tragic Monster: While he has a tear-jerking past, it's no excuse for the horrifying things he does.
- Used to Be a Sweet Kid: Once was a nice young boy from a more-or-less affluent family... until he and his little sister Yui were orphaned.
- Walking Spoiler: As one can tell, he's the most involves person in the plot besides Saiga and Kagura and his actions drive most of it.
- Woobie, Destroyer of Worlds: His ultimate goal is to die after destroying the corrupted culture of greed that Japan had become, as they forced him and his sister into a living hell.
Voiced by: Gara Takashima (JP), Pam Dougherty (EN), Elena Díaz Roledo (Latin-American Spanish)The ruthless, domineering and abusive mother of Kagura. A former actress who used to have some success back in her prime, she is now the head of the Tennozu Foundation, a powerful financial company that oversees the political and monetary landscape of Japan, often corrupting politicians and businessmen through the promise of indulgence in their basest desires in the Roppongi club.She highly resents her daughter for and is kind of a bitch in general.She is involved with Suitengu and unapologetically indulges in her lustful desires with him. Still good-looking for a woman her age, she doesn't waver in personally corrupting those who may obstruct her schemes or who just want to protect her daughter from her.
- Alas, Poor Villain: At least intended, considering Kagura's heartbreak when she's killed by Suitengu.
- Faux Affably Evil: Bitchy but polite all the same...usually...sometimes...well, whenever Suitengu's around. Which should say something.
- Abusive Parents: Starves her daughter and slaps Kagura around whenever she acts up.
- Big Bad Wannabe: She sees herself as the one in charge of Suitengu, when really it's the other way around.
- Depraved Bisexual: Rare Female Example, see her manipulative actions below.
- Died in Your Arms Tonight: In Kagura's right after Suitengu strangles her and shoots Gotokuji in the head.
- Evil Matriarch: Oh, is she ever. She's the head of Tennozu Group, putting her at the peak of Japan, and she's an absolute bitch about it.
- Flower Motifs: If she cuts one, it's never a good omen.
- Genre Savvy: She knew Suitengu was going to backstab her. Though, she still ended up getting the entire situation wrong, thinking he wanted to get with Kagura.
- Kick the Dog: Her treatment of Kagura is hideous, but one scene in particular stands out. After having malnourished Kagura, one of her teachers, Ms. Wakaba, promises to talk with Shinzen over it. Kagura returns home, only to find Shinzen having sex with Ms. Wakaba, and then giving her all the money she can carry... and making her leave without her clothes. On the way out, all Ms. Wakaba says to Kagura is to demand she give her a wad of bills she'd dropped while fleeing. The message is pretty obvious from Shinzen to her daughter: "There is nobody you can count on I can't take from you."
- Laser-Guided Karma: It's very difficult to feel sorry for her.
- Manipulative Bitch: Where to even start? She'll twist any sitution that doesn't revolve around her to suit her, usually at other people's expenses, mainly Kagura's and Suitengu's.
- Meal Ticket: To Suitengu but subverted in that she knows it all too well.
- Only a Flesh Wound: Shinzen shoots him in the leg for failing her, then demands he have sex with her in the pool before he bandages it. While the audience knows he can easily heal it, Shinzen doesn't know he's a Euphoric, so she seems to just think he'll be alright as long as it's bandaged before long. It's a subtle way to show that she's not nearly as smart as she thinks she is.
- Pet the Dog: She truly cares for her mentor, Ms. Gokutouji.
- Rich Bitch: See above.
- Smug Snake: Emphasis on snake. She freaks out when things start to turn against her.
- Used to Be a Sweet Kid: She once was a quiet, shy young actress with all of her dreams broken. Now look at her... she's a horrible bitch.
- White-Dwarf Starlet: She used to be a small-time but successful star, until she ran off.
- Widow Woman: The 15 years after were not good for anyone. She thinks he ran out on her, but he was dead.
- Woman Scorned: If she only knew the truth...
- Wrong Genre Savvy: Shinzen knew Suitengu didn't love her and only had her as his Meal Ticket... but she didn't know what he would do about it!
Tsujido, Makabe, Niihari & Kikukawa
Tsujido voiced by: Hiro Yuki (JP), Greg Ayres (EN), Marycel González (Latin-American Spanish)
Makabe voiced by: Hisao Egawa (JP), Bob Carter (EN), Daniel Jiménez (Latin-American Spanish)
Niihari voiced by: Kenjiro Tsuda (JP), Robert McCollum (EN), Emerson Gutiérrez (Latin-American Spanish)
Kikukawa voiced by: Kaoru Fujita (JP), Brina Palencia (EN)Tsujido, Makabe and Niihari are Suitengu's most loyal minions, a trio of gangsters he rescued from death at the hands of their superiors when he coincidentally chose to kill off those superiors so that he could take over their turf. Tsujido, noseless from the incident, is also a Euphoric; his fetish for smells has given him an incredibly sharp nose and the ability to track people by scent.Kikukawa is Shinzen Tennozu's right-hand woman, confidently handling any tasks her mistress presents her with and content to stay in the background.
- Anti-Villain: All of them. All of them commit terrible acts, but only so because they have the utmost devotion and gratefulness to Suitengu.
- Because You Were Nice to Me/I Owe You My Life: Tsujido, Makabe and Niihari feel this way to Suitengu, who rescued the three of them from horrifying fates.
- Bishōnen: Zig-zagged in regards to Tsujido. He is attractive, but we never quite see all his face with his prosthetic mask and bangs in the way. We do finally see his fully uncovered face when he was younger and he is good looking... except for the fact his nose had just been cut off while he was being tortured. The second time we see his entire face is during his fight with Ginza and the The Reveal of him as a Euphoric and his Transformation Sequence.
- Co-Dragons: Though Tsujido, Makabe, and Niihari could all fit into different roles in a Five-Bad Band, the fact that Suitengu holds them all in equal confidence, with none of them more loyal or trusted than the others, makes them closer to this.
- Creepy Crossdresser: Tsujido. The guy's basically wearing a Spy Catsuit with a frilly Absolute Cleavage neckline. Doesn't help the outfit he wears during the Ritual of the Goddess Ceremony is a sleeveless Bare Your Midriff top with evening gloves and Grade B Zettai Ryouiki boots. Officially, he was meant to give off "the atmosphere of having an Ambiguous Gender".
- Due to the Dead: In the epilogue, Niihari does a surprisingly noble version of this for his dead friends: he's collecting a crapton of money so that he can build three massive buildings. Kikukawa, whom he reined in, seems to approve gladly as he tells her of his project."What can I say, I'm a man with a dream. I'm gonna need me a crapload of cash so's I can build three towers downtown so damn tall they block out the sun. The tallest one, smack in the middle, I'll name 'The Suitengu Building,' and then, the ones on either side, I'm gonna call 'The Tsujido Tower' and 'The Makabe Plaza.' Now that's a dream that's fucking worth something!"
- Evil Is Hammy: Niihari mostly.
- Five-Bad Band or Five-Man Band?:
- Friendly Enemies: Played with. They are by no means friends to Saiga or Kagura but they hold no grudge against either of them. They just want to help Suitengu.
- Gayngster: Tsujido, though he's more concerned with his work.
- Heroic Sacrifice: Makabe, for Tsujido.
- Karma Houdini: Niihari and Kikukawa escape unscathed from the carnage and end up alive (and super rich) in the end.
- Our Were Wolves Are Different Tsujido.
- Punch Clock Villain: Most of them, Kikukawa in particular, have no interest in being assholes apart from their jobs.
- Rape as Backstory: With Tsujido. When Suitengu found him, he was strung up, naked, and a man was pulling up his pants.
- Satellite Character: Kikukawa, who stays mostly in the background although she shows up consistently.
- Subordinate Excuse: They are never seen questioning their horrible actions, but justify them with Suitengu.
- Unholy Matrimony: Niihari and Kikukawa are heavily implied to end up as such in the end.
- Villainous Friendship:
- The three Co-Dragons and Suitengu share a great big Type 1 with each other.
- Kikukawa's quick transfer to Suitengu's side without so much as a reaction indicates a Type II-IV mixture. Sort of hard to gauge given her inconsistent screen time. Maybe she and Suitengu bonded off-screen?
- You Are Not Alone/Stay with Me Until I Die: Invoked. Despite Ginza having knifed him in the neck, blasting him with a shotgun, and the Roppongi collapsing, Tsujido stayed behind in order to carry Suitengu to the generator so he could activate the Self-Destructive Charge.
Roppongi Club Euphorics
Euphorics in GeneralEvery single Euphoric we see barring Saiga is a part of the Roppongi Club, and it shows. All of them go after Saiga at some point or another.
- Cast from Hit Points/Cast from Lifespan/Power Degeneration: Overusage of Euphoric power can lead to death. Miharu and Kanda exhibit this. At least only Saiga's eyes are in danger from overuse.
- Leitmotif: Two of them: Theme of Euphorics will play whenever a new Euphoric is on the scene or is doing something evil, and Sweet will play whenever one of them is having a monologue or a flashback. The first lays to their more sinister aspects and the second is a sensuous theme that can be quite at odds with the scene at hand, especially the dentist's. You could also count Sorrow as one for Saiga and Suitengu.
- Removing the Head or Destroying the Brain: The only conventional way to kill any Euphoric.
- Sadist: They typically, and literally, get off on using their powers. Almost all of them abuse their powers and injure and/or murder innocent people in order to get off. The worst thing about it is that it isn't made clear if they were Evil All Along or if some sort of Roppongi conditioning turned them that way. Koganei and Miharu are two possible exceptions.
- Sex Is Evil: Their powers are just the most extreme expression of their fetishes.
- The Killer in Me: If Suitengu is to be believed, many of these people's basest desires involved bloody murder. The dentist's certainly did.
- They Look Just Like Everyone Else!: There really isn't any way to tell a normal person on the street from a Euphoric on the street.
Voiced by: Takehito Koyasu (JP), J. Michael Tatum (EN), Manuel Bastos (Latin-American Spanish)A great ballet dancer, but obsessed with flexibility (and, by extension, rubber) to the point of insanity. First seen breaking a would-be pupil's arm for not being flexible enough, he later becomes the first Euphoric to be seen in the series. His power is to become living rubber, a talent he uses to serve as an assassin for the Roppongi Club.
- Ax-Crazy: Murderous and psychotic.
- Catch Phrase: Flexible... flexible...
- Hoist by His Own Petard: The shard of mirror he impales Saiga with ends up used to blow his head off.
- Kick the Dog: That poor little girl whose arm he broke...
- Madness Mantra: He can often be heard muttering "flexible" or "rubber" in a low mumble.
- Off with His Head!: Saiga uses the mirror shard Kazuya impaled him with to blow his head off.
- Rubber Man: His power.
- Sissy Villain: He talks a big game, but is quickly taken out by Saiga, which isn't to say he's not a threat.
- Starter Villain: It only gets creepier and more fucked up from Shirogane onward, especially for poor Saiga.
Voiced by: Mari Yokō (JP), Colleen Clinkenbeard (EN), Maite Bolívar (Latin-American Spanish)The second Euphoric sent after Saiga to recapture Kagura. She is quite literally Made of Diamond, as this is her Euphoric Power: to turn her whole body into diamonds. A side effect (or cause?) of this is that she is quite addicted to diamonds, eating them by the dozen.
- Alas, Poor Villain: She ends up begging for her life and fleeing in terror of Suitengu, but doesn't get far.
- Femme Fatalons: She can grow them at will once she's used her power, and boy are they lethal.
- Foil: In a sense, to Kagura. Both are brunette females with almost everything in their life already paid for thanks to their loved ones. However, while Kagura's family is extremely abusive and outright seems to hate her and she would do anything to escape them, Koganei's husband loved her very much, and it seems she may have returned his affections, and forges his death into something worth continuing her current situation (read: addiction) over. These differences are gone into by Koganei herself during her episode.
- Gold Digger: Played with. Kagura points out how if she loved her husband, she should have told him he meant more to her than diamonds. However, she seems to believe that men's loves are defined by how much they'll give for it, at which point it becomes less about diamonds and more about the man's suicide.
- Literally Shattered Lives: Just to make things more disturbing, the last we see of her is a part of her head with her eye tearing up.
- Nigh-Invulnerability: Not much can hurt her, given she's made of one of the single hardest substances found in nature. Saiga and Suitengu get around this, however.
- No Sell: She's this to Saiga's camera power: his lens can't properly focus on her because she's transparent when made of diamond, causing the explosion to affect whatever's behind her instead. He wises up eventually and uses a paint can to allow his camera to focus on her.
- The Slow Walk: When she turns on the Club and goes after Saiga and Kagura herself. She's not the least bit worried about the camera pointed at her.
- You Have Outlived Your Usefulness: By Suitengu.
Voiced by: Shiro Gō; (JP), R Bruce Elliott (EN), Luis Miguel Pérez (Latin-American Spanish)A monstrous dentist who enjoys seeing people he works on writhe in agony. His Euphoric Power takes the fetish he has for teeth and translates it into spider-like surgical tool tentacles from his back, and more from his jaws and tongue.
- Animal Motifs: A spider. Victims trapped and helpless? Spidery limbs out of the back? Crawling around like one? All check. He even morphs his face into a spiderlike mandible with a drilling tongue.
- Cold-Blooded Torture: He loves this, and he doesn't care about his victims at all. When we see him work on Kagura, not only has he kept her awake for work (which involved removing a molar), he also did drilling on that molar that he admits was unnecessary, before yanking it out with pliers, with nerve lining still hanging onto the ends. And this is before he becomes a Euphoric. How this guy got a job is a mystery.
- Depraved Dentist: Duh.
- Nightmare Fetishist: If you haven't picked up on it by now, here's a bonus: the tooth he extracts from Kagura, he kisses and licks—messily, and sexually. He kept that tooth and drills on it in his spare time.
- Sadist: Oh, horrifically so. His first scene is him over a woman strapped down, whimpering in agony while he destroys her mouth with his tendrils. Whether he was one before or after he received his power isn't made clear, but it seems so.
Voiced by: Takeshi Kusao (JP), Christopher Bevins (EN), Luis Carreño (Latin-American Spanish)An esthetician with the power to bring his tattoos into reality, and "infect" other people by transferring them into their bodies.
- Artistic License – Physics: Blatantly. A parachute doesn't work if there's gaps in it like a fishing net.
- Boom, Headshot: Despite being affected by one of his spiders, Ginza manages to retain enough control to shoot him in the head and allow Saiga to finish him off.
- Hoist by His Own Petard: Seriously. When you're controlling people into shooting people you want dead, don't stand directly next to them.
- People Puppets/Puppeteer Parasite: He can do this with his tattoos, specifically the spider ones, and uses it on Ginza to try to get her to shoot Saiga dead.
- Your Mind Makes It Real: Ignoring that all Euphorics can supposedly do this, this is his specific power, turning his body art into weapons. He even keeps a knife handy with a skull tattoo as its holster.
Voiced by: Ryūzaburō Ōtomo (JP), Bill Flynn (EN), José Granadillo (Latin-American Spanish)
- A God Am I: The Roppongi Club was enough to get this man to not only turn on his faith (and empty church assets into it), but to believe he himself was God.
- Genius Bruiser: He electrocutes Saiga and Kagura, but not to kill them—to stop Saiga's cameras from working and being used against him. It doesn't work.
- Oh, Crap!: When he realizes Saiga still has a working camera.
- Psycho Electro: Absolutely insane with his power.
- Sinister Minister: The moment Kagura and Saiga flee, he's after them, with a cross on his back.
- What Happened to the Mouse?: After watching Saiga and Kagura escape, he's never heard from again. This is particularly jarring considering his power.
Voiced by: Maya Okamoto (JP), Laura Bailey (EN)One of the Roppongi Club's assassins, a Euphoric with the power to manipulate water and turn herself into a mermaid-like creature.
- Anti-Villain: She's one of the (apparently) few non-evil Euphorics.
- Death Equals Redemption/Hoist by His Own Petard
- Freudian Excuse: Her mother intended for them to drown together in a double suicide. It's implied this happened more than once before her mother finally died.
- Go Out with a Smile: How she dies.
- Kill It with Water: She can turn her body into water.
- Making a Splash: Her power.
- Offing the Offspring: Her Stage Mom tried to do this, which completely broke her.
- "Well Done, Son!" Guy: It's noted she really wanted to please her mother.
- The Vamp: Her backstory clearly involves her sleeping with and murdering men for their money and getting away with it.

- Black Shirt: On both sides. He's this for Suitengu and pretended to be so to the White Eagles, but detests what he sees as "pseudo-XYZ" reformists.
- Les Collaborateurs: A front.
- Large Ham/Evil Is Hammy: He loves the sound of his own voice a little too much, especially when talking to Saiga.
- Laughing Mad: After he reveals himself.
- Loud of War/Make Me Wanna Shout/Musical Assassin: His Euphoric power.
- Superpower Lottery: This guy can reduce metal pipes and concrete flooring to dust and send Saiga flying.
- "The Reason You Suck" Speech: Gives one to Saiga while determinedly pounding his skull with sound waves.
- Walking Spoiler: See above.
Voiced by: Takehiro Koyama (JP), John Swasey (EN), Luis Pérez Pons (Latin-American Spanish)The Prime Minister of Japan, and involved in the Roppongi Club up to his eyeballs, with plans to seize control of the club from Suitengu and place it under government control. A Euphoric, his fixation on food and eating gave him the power to mutate into a huge head-creature with acidic saliva, so he could more easily eat anything he pleased.
- Big Eater: His unique power.
- Evil Chancellor: As the Prime Minister of Japan.
- Fat Bastard: His Euphoric Power turns him into this.
- Game Face: "Even fatter bastard" is a crude way of putting it. In essence he becomes a giant, horrifically bloated head that drags itself around with tongue-leg appendages jutting out of its mouth.
- No, Mr. Bond, I Expect You to Dine: Invites Kagura to gloat over breakfast.
- No Name Given: His first name is never mentioned in the series.
- The Starscream: Initially under Suitengu's thumb as a member of the latter's club, he later makes a way to place the club under government ownership and plots a hostile takeover of the Tennouzu Group. Suitengu easily brushes off the takeover attempt and kills Kamiya in response.
- Voluntary Shapeshifting: He can turn himself into a HUGE spidery monster.
Voiced by: Kouji Ishii (JP), Antimere Robinson (EN), Héctor Indriago (Latin-American Spanish)A flamboyantly gay American man whose passport was invalidated, trapping him in Japan, Bob runs a massage parlour out of his apartment and lives in the same building as Saiga. The two are friends, and Bob is a good person, so he regularly tries to help Saiga as he gets more caught up in the mess with Suitengu and his Roppongi Club. Bob has a sister (a male-to-female transsexual) named David, who runs "Le Pub David", a cabaret staffed by male-to-female transsexuals.
- Camp Gay: Incredibly so.
- Hidden Depths: After Saiga and Kagura come to stay with him, he gives Saiga a meaningful talk, without even the high-pitched voice. Though his heart is in the right place, he's mistaken in thinking Saiga wants a relationship or is attracted to Kagura.
- Nice Guy: He may be camp to an irritating degree, but he's always there to lend an ear for Saiga and support him and Kagura.
- Only Sane Man: He sticks out as not having a single power nor alliance.
- Pet Homosexual: To Saiga.
- Plucky Comic Relief: Very happy and outgoing, which is saying a lot given the show's tone and it's dour characters. Played for Laughs usually, though he also has some serious scenes, too.
Voiced by: Rikiya Koyama (JP), Kent Williams (EN), José Manuel Vieira (Latin-American Spanish)A doctor that was responsible for operating on and saving the life of Saiga after he was pulled from the rubble of the bioweapons lab where he unknowingly contracted the Euphoria Virus. Afterwards, he got married and settled down in a private clinic in Japan, until his wife died of cancer. After Saiga becomes a Euphoric and rescues Kagura, he comes to Genba for assistance in finding out what is wrong with the both of them.
- Action Survivor: Like Saiga, he was on the war lines too.
- Hospital Hottie: He's very Tall, Dark and Handsome. Which might be why Ginza ends up with him in the end.
- Non-Action Guy: His area of expertise is medicine, not fighting.
- The Medic: See above.
- Weak, but Skilled: He manages to take out a soldier, steal his gun, and shoot Mizunokuchi, saving Saiga from a horrific death seconds away.
David's PubDavid is a male-to-female transsexual and Bob's sister. He runs a dance show parlor staffed with other male-to-female transgenders and transsexuals, and they support Saiga and Kagura for a short time. They also quickly stand up to the Euphoric Kagonei when she attacks.
- Badass Bystander/Heroic Bystander: Most people without their own Euphoric powers don't survive assaults by Euphorics. These girls do.
- Defiant Stone Throw: The club staff are very clearly outmatched by Kogane and know it, but that doesn't stop them from buying Saiga time by throwing bottles at her.
- Mugging the Monster: Quite literally.
- Weaksauce Weakness: Funnily enough, at least one of them assaults Kogane with a bottle, which of course breaks. It may have been this that gave Saiga the idea to take down Koganei the way he did—if she's no longer transparent, she becomes vulnerable to him.
Joe (real name Joji Kitamura)
- Cruel and Unusual Death: Ochiai kills him and most of the other people in the room with sound waves strong enough to make his skull crack and bleed. Saiga does not take kindly to this.
- While he's drinking with Saiga, he expresses that if he found a way to help the hellhole Japan's become, he'd gladly give his life to do it. That's exactly what happens the next day.
- Joe's seen in the first minute of the episode getting told off for seemingly not standing up for his girlfriend. At the end, he tries standing up for something he loves and pays for it.
- Mauve Shirt: He's actually one of the better characterized Muggles in the show. He has enough time to make Saiga smile over drinks before he dies the next day.
- Pietà Plagiarism: Joe gets this from Saiga after he's died, and from the journalist chief as well.
- Tragic Mistake: See above. Saiga tells Joe the night before that running and hiding is a smart option, but instead Joe follows the philosophy he learned from Saiga. Unfortunately, this choice leads him to confront Ochiai, directly leading to his murder.
- We Hardly Knew Ye: Poor Joe gets killed off in the same episode he's introduced in.
Chief Ekoda and the Piano Teacher
Ekoda is voiced by: Naoki Makishima (JP), Mike Mc-Farland (EN)Though entirely unrelated, these two share some disturbing habits: severing and collecting body parts. For Kagura's Piano Teacher, it's hands, while for Ekoda, it's legs. Ekoda is not a Euphoric; whether the pianist is one is never expounded on.
- Creepy Souvenir/A Love to Dismember: The piano teacher cuts off hands and sticks them on to mannequins, and is looking for a pair to replace the rotting ones on the mannequin most important to him, which he identifies as a lover, and wants Kagura's for them. Ekoda cut off his wife's and daughter's legs and preserved them in a trophy room, and would have done the same to Ginza.
- Chainsaw Good: Ekoda uses one to do his sick collecting with.
- Murderous Thighs: Ekoda gets a little too close, allowing Ginza to literally break his neck with her thighs.
- What Happened to the Mouse?: We never see the piano teacher again after the lesson.
