[[folder: Main characters]]

!!Nai
-->'''Voiced by:''' Creator/HiroShimono (Japanese), Sean Michael Teague (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/235579.jpg]]

A boy seemingly unknowing of the ways of the world -- including the concept of blood -- who nonetheless braves it in order to search for his former caretaker, Karoku, an enigmatic figure who parted ways with him before the story began.
----
* CheerfulChild: Though his age is unknown. He could be anywhere from 10 to 15, really.
* ChildrenAreInnocent: He knows next to nothing about the world except what Karoku taught him, unknowing of what "blood" is and what it means when it's splattered outside the body.
* ConstantlyCurious: He's always running off and getting lost in crowds because of this.
* EverythingsBetterWithRainbows: [[spoiler: It's what his species name, Niji, means. He originally lived in the Niji Forest, and he later somehow casts a large rainbow in order to find Karoku. ]]
* GoodIsDumb: Justified, [[spoiler:considering that he was originally a cute little animal]], and looks like and is later referred to being a child as well. However, unlike some character types who remain clueless throughout the story, he's slowly learning more about the world.
* HumanityEnsues: Originally a cute animal called a Niji, he was somehow transformed into a human in an as of yet unspecified way.
* InnocentInaccurate: He described blood as "red water."
* MoralityPet: Seems to be one for just about everyone in Circus to a varying degree, but none more so than with Gareki.
* NiceGuy: Very kindhearted and gentle.
* RedEyesTakeWarning: Subverted, he is incredibly naive and would barely hurt a fly... [[spoiler:unless an animal was about to kill Karoku.]]
* RidiculouslyCuteCritter: In Niji form.
* SuperSenses: Despite his not having any offensive abilities at the moment, Nai is far from being TheLoad, as his elevated hearing has more than once been crucial in ensuring the survival of those around him, and later, useful during missions.
* TenderTears: Several times, most notably in episode 3.

!!Gareki
-->'''Voiced by:''' Creator/HiroshiKamiya (Japanese), Creator/GregAyres (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/194847.jpg]]

An intelligent and resourceful young man, Gareki starts the story engaged in corrupt business before things take a very wrong turn. In the midst of the chaos that ensues, he somehow saves Nai from the vile woman he originally meant to rob, and becomes involved in the mystery surrounding the boy while they are on the run.

After Circus takes Nai into their custody, he's determined to stay for his own gains, but in truth he may care more about those around him than he likes to let on, even to himself...
----
* BadassNormal: He doesn't have any special powers like the rest of the cast. His weapons of choice tend to be guns and explosives he makes himself.
* BigBrotherInstinct: He develops this behavior for Nai. At one point, he encouraged Nai to run off without him so that he wouldn't be attacked by a Varuga. He also developed this to his foster siblings, Yotaka and Tsubame.
* BringMyRedJacket
* CelibateHero: In chapter 12, Yogi mentions how cool Gareki can be when Gareki easily shoots down a bracelet in a booth that Yogi had been trying to get, and how he probably has several girlfriends. However, we see no evidence that Gareki's interested in girls, or romance in general.
* [[spoiler: CombatMedic: Currently in training to be such.]]
* DarkAndTroubledPast: He was sold by his parents to a human trafficking group. While being transported, the ship he was on crashed. He was later picked up by Tsubaki who took care of him along with her younger siblings. [[spoiler:She was later killed by Yotaka who was transforming into a Varuga due to the medicine that she received from her "boyfriend". What makes her death more tragic is the fact that Gareki warned Tsubaki not accept the medicine and she didn't listen to him, not out of malice, but out of love for her siblings.]]
* [[DefrostingIceQueen Defrosting Ice King]]: Nai (unwittingly) and Yogi (determined) together with other Circus members have gotten him to open up considerably.
* GadgeteerGenius: Made particularly apparent through his contribution to the mission [[spoiler:to save Karoku]] in volume 7.
* GogglesDoNothing: Averted. He's wearing them in his first appearance, having just blown up a portion of the mansion where he meets Nai. They don't get much use after that, though this is justified by the fact that he has no need for explosives after being taken aboard Circus's second ship.
* TheGunslinger: What he might be, if Circus allowed him to use his gun.
* {{Handguns}}: Gareki likes using them. Circus doesn't like his use of them.
* HealthcareMotivation: [[spoiler: He originally got into thieving to pay for his foster grandfather's medical bills.]]
* JadeColoredGlasses: The losses in his childhood, which includes being sold as a slave by his parents and seeing his ParentalSubstitute being exploited, as well as life on the street have made him very cynical about people (himself included) and unwilling to make friends.
* TheSmartGuy: Despite the implication of his street savvy, Gareki's shown and later noted to read frequently during his time in Circus, which heightens the poignancy when what he was reading up on is revealed in a conversation with Hirato in chapter 38. His skills as an unsung GadgeteerGenius backs this position up further.
* StreetUrchin: Gritty type. Prominent early on, though the circumstances over why are explained later. He does mellow down once he and Nai wind up with Circus, becoming broodier and using less dirty tricks. His sharp intellect's evident throughout, however.
* StuffBlowingUp: Is very knowledgeable about explosives. He was even introduced setting up a bomb.
* {{Tsundere}}: Gareki can be a platonic Type A, especially when Yogi teases him. Also to Nai, though less violently. He's normally aggressive verbally and physically, but when he's around friends or family, he shows his dere side.

!!Karoku
-->'''Voiced by:''' Creator/SoichiroHoshi (Japanese), Creator/VicMignogna (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/karoku_karneval_277.jpg]]

The mysterious young man whom Nai is looking for. Little is known about him, but it appears that he was always with Nai and suddenly disappeared one day, leaving behind a trail of blood and an outdated Circus bracelet. [[spoiler:It's revealed that there are actually ''two'' Karokus, and chapter 57 confirms them to be brothers.]]
----
* AloofBigBrother: For the most part, but it's [[spoiler:subverted in chapter 52, where he breaks down in tears when Nai is close to death]].
* DarkAndTroubledPast: As the Circus bracelet left behind in blood indicates.
* EvilTwin: It's very possible that [[spoiler:the Karoku who is working for Kafka is this to the one who took care of Nai.]]
* KidnappedScientist: If he really was involved in [[spoiler:the creation of Nai, who's successfully existing as a new hybrid species]], then it is very likely that he was abducted for his knowledge of [[spoiler:genetics as well as his ability to create a stable life form, an aspect in which Kafka's valga have fallen short.]]
* ManipulativeBastard: [[spoiler:He seems to manipulate events around him for his benefit. This is an implication that this Karoku isn't the same person that Nai was with before.]]
* NiceGuy: Nai thinks of him as "as warm as the sun". [[spoiler: Later events hint that there's something sinister about him, but only when "the other Karoku" is in control]].
* NotSoStoic: In chapter 52, after [[spoiler:regaining his memories of Nai]], he loses his usually composed disposition and breaks down in tears when [[spoiler:Nai is close to dying from his injuries]].
* PsychicLink: He seems to be able to communicate with Nai this way under certain circumstances.
* TeenGenius: Heavily implied to have had a hand in [[spoiler: the creation of Nai as a Niji-human hybrid]].
* TraumaInducedAmnesia: After he's rescued from [[spoiler:Kafka by Circus, his memories become so scrambled that he entirely forgets his relationship with Nai. Dr. Akari suggests it's because of the stress of his previous circumstances.]]
* YourDaysAreNumbered: Implied. [[spoiler:A servant of the Kafka manor where he is staying comments that it's a waste to feed him.]]
* YouHaveOutlivedYourUsefulness: Implied when he suddenly tells Nai through their telepathic communications that [[spoiler:he's going to be killed soon if Nai doesn't come rescue him.]]

[[folder: Circus Second Ship]]

!!Hirato
-->'''Voiced by:''' Creator/DaisukeOno (Japanese), Creator/IanSinclair (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/hirato_portal.png]]
----
* CaneFu: Hirato's weapon of choice, with the special attack "Vakuum."
* TheCaptain
* FatherToHisMen: His affection for his crew is more concealed than most examples of this trope, and may manifest in strange ways (due to his love of provoking others), but he does things like buying candy and souvenirs for Nai and arranging for Gareki to attend school in the hopes of getting his license to officially join Circus. These tendencies are perhaps best viewed in his interactions with Tsukumo, though YMMV on whether you read it in a romantic context or not.
* {{Foil}}: To Akari. Hirato is a seemingly friendly BitchInSheepsClothing whose job is to eliminate lives, while Akari is a serious JerkWithAHeartOfGold whose job is to save lives.
* ManipulativeBastard: And [[MagnificentBastard always seems to have a plan and is one step ahead of everyone else]].
* NobleDemon: Says to Akari rather wistfully that it's his job to take lives but as seen in flashbacks with his first encounter with Yogi, Hirato is not quite as ruthless as he'd like everyone (and himself) to believe. Not to mention how protective he is of his "children".
* PapaWolf: He may be the StoicGlasses and furthermore, a ManipulativeBastard, but Hirato does NOT like it when people mess with his "children."
* ParentalSubstitute: His increasingly coming off like one or some kind of familial figure to Gareki (and Nai), despite being a bit aloof, is lampshaded a few times later on in the series, including by allies on the Third Ship.
* PassiveAggressiveKombat: Master of this, as part of his ManipulativeBastard package. PlayedForLaughs when he's around Akari.
%%* ScaryShinyGlasses: On occasion.
%%* StoicSpectacles: Hirato fits this to a T.
* TranquilFury:
** Though almost impossible to read most the time, he has a moment of this as early as chapter 14 when, after Yotaka fought against and injured Yogi, he pursued the person responsible and just after talking with him calmly, says, "It is enjoyable to torment, isn't it?", (even sporting a [[DissonantSerenity pleasant smile]] to boot) before having his banshees ''tear him apart''.
** Another time this happens is in chapter 35 when [[spoiler:Azana betrays and tries to kill Akari]]. He doesn't [[DissonantSerenity smile]] this time or have any [[DeadpanSnarker sarcastic remarks]], but he knocks [[spoiler:Azana]] away and calmly states the punishment for attacking someone of [[spoiler:SSS rank]] before attacking. If [[spoiler:Akari]] hadn't stopped him, he would have killed [[spoiler:Azana]] without a second thought or any emotion on his face at all despite his anger. [[spoiler:Do not dare to hurt Akari.]]

!! Yogi
-->'''Voiced by:''' Creator/MamoruMiyano (Japanese), Creator/ChristopherBevins (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/yogi_karneval_165.jpg]]

-->"The soaring male spirit, the heart-throbbing sparkly prince, National Defense Organization 'Circus' Second Ship member Yogi!"
----
* AdorablyPrecociousChild : His greatest concern as a child was not being able to [[spoiler: become as good a king as his father]] so he spent a lot of his youth studying [[spoiler: politics]] and body-guarding his sister.
* AfraidOfDoctors: Specifically of Doctor Akari, to the point of amusement for the audience. Becomes less amusing once [[DarkAndTroubledPast the details of his childhood]] [[spoiler: as an experimental subject in various medical and biotechnological research labs]] are revealed, though admittedly he [[LaserGuidedAmnesia doesn't remember them]]. But his memories of [[spoiler: being experimented on in Akari's lab weren't lost]], so the phobia is pretty self-explanatory once his backstory is revealed.
* AfterActionHealingDrama: He tends to get badly injured more often than the other main characters, requiring treatment from Akari or even hospital stays. Of special note are the Rinoll and Merumerai arcs.
* AlternateIdentityAmnesia: Golden!Yogi and Silver!Yogi don't seem to clearly share memories between each other, though the silver persona is more aware of what the normal one is doing than vice-versa.
* BewareTheNiceOnes: Can become pretty badass when the need calls for it, despite his default NiceGuy persona.
* BigBrotherMentor: To Gareki (mainly about enjoying life and bonding with other people) and Nai.
* BrokenTears:
** In chapter 18, after [[spoiler: the allergy patch that holds back his split personality falls off]], tears start streaming down his face for no reason other than this. Given his usually sunny disposition, it's quite disconcerting.
** Happens again in chapter 102 when [[spoiler: his memories return]].
* ButtMonkey: Gets a lot of abuse from pretty much everyone except Nai; most notably Gareki (of the physical sort), Hirato (of the verbal sort) and Eva. Kiichi, Akari, and the Second Ship's doctor pitch in from time-to-time as well.
* CrouchingMoronHiddenBadass: Usually acts like a ditz, but is capable of both intelligence and badassery when things get serious.
* CuddleBug: He enjoys giving hugs to his teammates.
* DarkAndTroubledPast: [[spoiler: The cause of both his SplitPersonality and TraumaInducedAmnesia.]] It was a good life at first, and then everything went to hell.
* TheDitz: His default persona.
* DualWielding: Two épées made of strong, thorny vines.
* EscapedFromTheLab: As his backstory reveals; though he was technically ''rescued'' from it, he'd [[spoiler:killed all the workers there by the time he was found by Circus... and taken right back to ''their'' lab]]. Poor kid.
* ForcedToWatch: [[spoiler: As a ten-year-old, was strapped to his surgery table and forced to watch a video where his little sister was literary torn to shreds, all while pleading for his help]].
* FriendToAllChildren: His role in the acts that Circus puts up, but he's genuinely fond of kids and the kids love him, too.
* GreenThumb: Yogi's weapons are two thorn-like épées, and he can conjure up thorny vines with them as well. Combined with ScarfOfAsskicking in chapter 19, whereupon [[spoiler:the badass split personality of Yogi saves Gareki from the split personality's own attack this way.]]
* HarmfulToMinors: [[spoiler: Being forced to watch his nearest and dearest being brutally killed at the age of ten]].
* HairOfGoldHeartOfGold: Unarguably one of the two nicest characters in the story: always willing to help out when he can, loves children, and is very apologetic and genuinely saddened when they have to kill someone.
* HeroicBSOD:[[spoiler: Finding the decapitated corpses of his caretakers as a child. Relives it again when his memories return]].
* HiddenDepths: Yogi can be melodramatic and flamboyant one moment, then more serious than Kiichi the next. There's definitely a lot of this going on, and it's slowly revealed over the course of the series.
* {{Keet}}: Except during serious fights/situations, he's always bright, loud, cheerful and sports a childish streak a mile wide. However, [[HarsherInHindsight later events in the manga hint that]] this is likely due to [[spoiler: the ten-year gap in his memories]].
* KnightInShiningArmor: His "role" in Circus shows, hilariously combined with a mascot costume.
* NiceGuy: See the HairOfGoldHeartOfGold entry, above.
* ThePatientHasLeftTheBuilding: When he ran away to Vinto.
* PointlessBandAid: Averted. It's actually a medicinal patch that administers allergy medicine. [[spoiler: And, strangely, keeps his split personality in check]].
* StepfordSmiler: Somewhat. [[spoiler: Silver!Yogi in particular is this to a tee]].
* SoleSurvivor: [[spoiler: Of the tragedy in his home country. Later subverted when we learn that his younger sister also survived]].
* SomethingAboutARose: The kanji for one of his defense techniques is "Rose Barrier."
* [[spoiler:SplitPersonality: His usually gold hair turns silver as an indication]].
* SunnySunflowerDisposition: Which makes it all the more shocking how his behaviour changes when his other personality manifests itself and, later, when his memories start to resurface.
* TraumaInducedAmnesia: [[spoiler: He doesn't remember the first 10 years of his life because of the terrible experiences he went through as a child. His other self seems to have retained some memories, but disregards them as ''nightmares'']].

!! Tsukumo
-->'''Voiced by:''' Creator/AyaEndo (Japanese), Creator/JadSaxton (English)

--> "Numerous stars fall from the sky. The little lamb knows the sky. National Defense Organization Circus Second Ship member Tsukumo."
----
* ActionGirl
* [[BigBrotherMentor Big Sister Mentor]]: To Gareki and Nai.
* DiesWideOpen: [[spoiler:At the end of episode 9, courtesy of Karoku. However, by the start of episode 10, [[DisneyDeath she was later]] [[BackFromTheDead brought back to life by Hirato.]]]]
* DisguisedInDrag: Does this with Kiichi while undercover on a later mission.
* DistressBall: She's usually competent, but when the plot calls for someone to be rescued, well, it's either her or Nai.
* EvenTheGirlsWantHer: In-universe, Eva.
* HeroicSelfDeprecation: She constantly questions if she has fulfilled her duties, and frets when something's less than perfect.
* LadyOfWar: As her specialty is in acrobatics.
* LightEmUp: Her powers and attacks involve stars and constellations.

* TheStoic
** NotSoStoic: When her teammates are in danger.
* SugarAndIcePersonality: Normally quiet and emotionless, but sweet and protective towards her teammates.
* UndyingLoyalty: To Hirato.
* WaifFu: Tsukumo is ''extremely'' strong despite how petite and slender she is.

-->'''Voiced by:''' Creator/KojiYusa (Japanese), Creator/JMichaelTatum (English)
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/212601.jpg]]
----
* TheAlcoholic: PlayedForLaughs
* TheCaptain
* {{Foil}}: The noisy, cheerful and seemingly silly Captain to Hirato's calculated and suave manners. He's by no means incapable though.
* TheFool
* FriendlyAddressPrivileges: Loves to call Akari-sensei "Akari-chan", a fact that irritates the doctor as he is older than him. According to the short extra after chapter 72, he even called him that when Akari used to be his instructor in Kuronomei.
* HeavySleeper/NotAMorningPerson
* [[spoiler:HiddenDepths]]: While he comes off as much more laid-back than Hirato and Akari, [[spoiler:his expression turns quite sinister at one point when he asks Tsubame what she's willing to sacrifice to protect the people around her.]]
* LargeHam

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/kiichi_karneval_48358_7.jpg]]

----
* ActionGirl

* DisguisedInDrag: Does this with Tsukumo while undercover on a later mission.
* ElegantGothicLolita
* LittleMissBadass
* OlderThanTheyLook: She definitely doesn't look fifteen.
* PetTheDog: Despite her usual tsun to everyone, she was the only one who comforted Nai when [[spoiler: the amnesiac Karoku wasn't at his best with him. It's hinted a bit later that she really does care for him. ]]
* TheRival: To Yogi in particular because she resents having the same grades as him, whom she thought useless because of his unwillingness to harm others.
* SinisterScythe
* ThirdPersonPerson: There are times where she slips into this while she talks in first person other times.
* {{Tsundere}}: A fierce type A to anyone she considers slacking off or not trying hard enough. She does have her rare dere moments though.

----
* BigCreepyCrawlies: What his more powerful attacks involve.
* BitchInSheepsClothing: Zig-zagged. Underneath his politeness, he is actually aloof and capable of nasty words and actions, as Gareki learns firsthand. On the other hand, he's dedicated to his comrades, as a true Circus member will.
* DyeHard: His hair is actually gray, but he constantly dyes it.
* JerkWithAHeartOfGold: When he's not being a BitchInSheepsClothing.
* MadScientist: He loves experimenting with medicinal herbs and dangerous plants.

[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/akari_9.png]]
----
* AlwaysSomeoneBetter: To Azana.
* BrutalHonesty[=/=]DeadpanSnarker: "What's wrong with telling the truth? If you don't like it, then improve things!" That line says it all. [[http://24.media.tumblr.com/5485b57254a4498165bbc20f7e2ad5ce/tumblr_ms1uinDOc71r8m2o5o1_500.jpg Another example]]
* BunniesForCuteness: The flower bunny that he takes care off is meant to represent his soft side. In the fanbook it is stated that it brings him joy to take care of it. I mean the bunny refuses to return to the wild to stay with him. You cannot get any cuter than that.
* TheCharmer
* CrossPoppingVeins: When he is angry but not yelling
* ColorContrast: Black/White contrast with Hirato as another way to remark their foil status.
* CurtainsMatchTheWindows: Light pink hair and light pink eyes.
* DressedToHeal
* DrJerk: In Yogi's opinion, but not really true.
* {{Foil}}: To Hirato. Akari is a serious JerkWithAHeartOfGold whose job is to save lives, while Hirato is a seemingly friendly BitchInSheepsClothing whose job entails taking lives.
* FriendToBugs: In the Drama CD of a character song it was revealed that he likes insects and would not allow Hirato and Tsukitachi to harm one when it escaped and ruined his lab.
* FreudianTrio: The Super Ego, Hirato is the Ego and Tsukitashi the Id.
* FoodSlap: In the Drama CD's when Hirato and Tsukitachi upset him too much, he threw wine to both of their faces.
* GoodIsNotNice: Although he is a very kindhearted person and means no harm, he is rather harsh and domineering.
* HospitalHottie: It's {{Lampshaded}} with the nurses, who both fawn over him and hilariously deny him whenever he tries to use his charms to make them do things.
* JerkWithAHeartOfGold [[http://24.media.tumblr.com/49a59f557c636542ad6b347a8202c9a1/tumblr_mpd3zbDviv1s129zlo1_500.jpg]]
* [[spoiler:ParentalSubstitute for Azana.]]
* LabcoatOfScienceAndMedicine: In this case is both since he is both a doctor and a resercher. Almost never seen without it.
* MessyHair: He actually looks younger and nicer with it.
* MrExposition: Most of his conversations involve him explaining something to someone else.
* NamesToTrustImmediately: Part of the Vinto arc was about how the drugs were distributed because someone was using his name.
* NoSenseOfHumor: Once again lampshaded by Tokikatsu in a omake. [[http://z.mfcdn.net/store/manga/4533/09-054.5/compressed/j005.jpg Here]]
* NotSoStoic: When he discovers that Azana was poaching in vinto and then when he tells him that he hates him. It is far more dramatic in the CD drama, but the face he makes in the anime was really sad. [[http://24.media.tumblr.com/4f37be6b1b8080e316d4b0495fe408ac/tumblr_mp30s8KBcU1r1xo14o1_500.gif]]
* OmnidisciplinaryScientist[=/=]SuperDoc: Not only does he have medical knowledge, he also has knowledge and does research concerning biology, archeology, genetics and pharmacology as he is the Research Tower´s Research Chief Specialist. Relating to his medical knowledge he is also a surgeon, an expert in emergency medicine, fixing fractures, making his own medicine (Yogi's allergy patch). That indeed takes a lot of different medical specialties. No wonder he is a SSS rank.
* PerpetualFrowner: You almost never see him smile unless he's smirking.
* ProudElite
* SitcomArchnemesis: Mainly to Hirato.
* SpockSpeak[=/=]TechnoBabble: He always talks in very scientific terms, most notably in the manga, especially when making explanations.
* TheStoic: [[http://24.media.tumblr.com/bf8ccd2dc612a62f323ee0365bd82bb3/tumblr_mq908gsHNT1soxrufo1_500.jpg]]

* VitriolicBestBuds: Although he acts antagonistic towards Hirato and Tsukitachi he ends up spending his free time with them drinking (initially not willingly of course). Both Hirato and Tsukitachi both care for him as well and make sure he takes a break once in a while. They were both worried for him after the incident with Azana.
* {{Workaholic}}: He does not believe in taking breaks or rest. It is {{lampshaded}} by Tokikatsu in a message he sent him.
