(Names displayed in Western order.)
[[folder:Loveless Team]]
'''Ritsuka Aoyagi'''
->Voiced by: Creator/JunkoMinagawa
* AbusiveParents: His mother is constantly having a mental break down and hurting him in the process. His father hardly seems to care, spending more and more time at work in order not to deal with the situation at home. Seimei was the one who actually did the looking after Ritsuka, while their father only intervenes to whenever his wife's behavior starts to annoy him.
* BigBrotherWorship: Played completely straight.
* [[CantStandThemCantLiveWithoutThem Can't Stand Him, Can't Live Without Him]]: His relationship with Soubi.
* CatBoy
* [[DefrostingIceQueen Defrosting Ice King]]: He warms up to Soubi a ''lot'' compared to how he was when the two met.
* EvenTheGuysWantHim
* NewTransferStudent: At the beginning of the story.
* OneHeadTaller: The reverse and exception, played straight (without the humor).
* PointlessBandAid: Frequently has a bandaid on his face, and though it looks like this trope at first, [[{{Deconstruction}} it's not]].
* SillyRabbitIdealismIsForKids: Implied upon with his "missing" personality and his current one.
* StepfordSmiler: He smiles often to show that there are no problems to people outside his house.
* [[TellMeAboutMyFather Tell Me About My Brother]]: Subverted and played straight. He does have his memories of Seimei, but he is ''constantly'' asking about him for one reason or another.
* TroubledButCute: And his counterpart is indeed [[BrokenBird Soubi.]]
* {{Tsundere}}: Especially around Soubi.
* TheUnchosenOne
* WiseBeyondTheirYears: He known for reading very complex books for a hobby.

'''Soubi Agatsuma'''
->Voiced by: Creator/KatsuyukiKonishi
* BerserkButton: Doesn't like being reminded of his "training" with Ritsu. Nisei's mere existence also qualifies as well.
* BrokenBird
* CombatSadomasochist: He insists to be dominated by Ritsuka. Though he was raised to be like that.
* [[spoiler:DefiledForever]]: Thanks a lot, Ritsu.
* EvenTheGuysWantHim: Ritsuka, Seimei, [[spoiler: Ritsu]], Kio...
* ExtremeDoormat: Not surprising, given his background.
* [[spoiler:FriendlessBackground]]: Kio notices.
* TheGlassesComeOff: Whenever he starts a battle.
* NoNameGiven: [[spoiler: In-universe, he actually does not has a name, such as Beloved and Loveless, he is a blank Fighter that can be assigned to any Sacrifice.]]
* NotSoStoic: Shown with a few examples, but most notably [[spoiler:when he meets Seimei again for the first time during the present storyline]].
* OneHeadTaller: Though certainly more than a head taller than Ritsuka, he often gives him comforting hugs. Sometimes inverted with Ritsuka, though not for humor.
* [[spoiler:ParentalAbandonment]]: [[spoiler:His parents died when he was only six years old in an accident.]]
* [[spoiler:RapeAsBackstory]] Though not his entire background, it's still a rather important part of it.
* SinsOfOurFathers: [[spoiler:Ritsu abused him because his mother married another man. Yeah, Ritsu's a jerk.]]
* StepfordSmiler: Extreme Type B.
* UnstoppableRage: Even if Ritsuka hadn't ordered him to fight Nisei, [[RoaringRampageOfRevenge he probably would have found an excuse to fight him anyway]].

[[folder:Beloved Team]]
'''Seimei Aoyagi'''
->Voiced by: Creator/KenNarita

* [[spoiler:AuthorityEqualsAsskicking]]: Heavily implied.
* [[spoiler:TheBadGuyWins]]: In volume eight.
* [[spoiler: BeautyIsBad]]: [[spoiler:Very bad. [[InformedAttribute He has even been described]] as having beautiful ears and a beautiful tail.]]
* [[spoiler:BewareTheSuperman]]
* [[spoiler:BigBad]]
* [[spoiler:TheCowl]]
* [[spoiler: TheDreaded]]
* [[spoiler: HeroKiller]] So very much.
* [[spoiler:ManipulativeBastard]]: [[LampshadeHanging Lampshaded]] a few times, most notably by [[spoiler:Youji, during the attack on the school]].
* [[spoiler:FakingTheDead]]
* IdentificationByDentalRecords: How his body was ID'd. [[spoiler:Subverted, like ''whoa''.]]
* PosthumousCharacter: [[spoiler:Subverted big time.]]
* PuritySue: He's [[InvokedTrope described]] as perfect and loving in all the flashbacks seen of him. [[spoiler:Thoroughly subverted once he shows up again in the story, but he tried to show up like that to his brother.]]
* ShroudedInMyth
* [[spoiler:SlasherSmile]]
* WalkingSpoiler: [[spoiler: He is very much alive, and is the BigBad.]]
* [[spoiler:{{Yandere}}]]: [[spoiler: For Ritsuka, he is willing to kill, rape and wreak havoc, even if it's not what Ritsuka wanted.]]

'''Nisei Akame'''

* BeautyIsBad
* BlessedWithSuck: Namely when your destined partner doesn't really give a crap about you unless it's convenient for him.
* BreakTheCutie: He tries. Though he doesn't get one hundred percent of the wanted results, he's at least somewhat successful.
* DontYouDarePityMe: Inverted. He ''wants'' to be pitied. He would probably think a [[GetOutOfJailFreeCard get-out-of-jail-free card]] would have been nice, too. He was quite upset to not having been shown any sympathy.
* EnigmaticMinion
* EvilCounterpart: He's similar to one for Soubi, as they are [[spoiler:both Seimei's Fighters]].
* ForTheEvulz: It's just another way of having fun.
* ManipulativeBastard
* NothingCanStopUsNow: Until he realizes he actually ''can't'' win in his fight against Soubi and Ritsuka.
* PsychopathicManchild: Love could go die in a ditch and he'd still be happy.
* SlasherSmile
* ThisMeansWar: He is certainly ''not'' on good terms with Soubi.

[[folder:Non-Combatant Students]]
'''Yuiko Hawatari'''
->Voiced by: Creator/KanaUeda
* ExtremeDoormat
* HugeSchoolgirl: And how!
* LoveYouAndEverybody
* PluckyGirl
* ShipperOnDeck: For Ritsuka and Soubi. (Though a good number of the fans [[OpinionMyopia hate her regardless]], simply because of her MatchmakerCrush on Ritsuka.)
* WiseBeyondTheirYears: Noticeably averted. She is the only 12 year old of the main cast who actually ''acts'' like a 12 year old, with the naiveté and innocence of one. This tends to clash a little with the Zeroes (male) and Ritsuka, who all act far more mature, and adds to her RonTheDeathEater treatment and the label "stupid" (There's never evidence that she is, she's just the only one who acts their age!). Ritsuka himself later admits that she's ''not'' actually stupid, and in fact he seems to envy her.

'''Yayoi Shioiri'''
->Voiced by: Creator/JunFukuyama
* {{Adorkable}}
* CatBoy
* IllBoy
* RapunzelHair

'''Kio Kaidou'''
->Voiced by: Creator/KenTakeuchi
* [[spoiler:BigScrewedUpFamily]]: He comes from one.
* BlindWithoutEm: Implied. He looks ''really'' good in them though so it works out.
* EroticEating: He's almost always eating a lollipop.
* TheNicknamer
* OralFixation: Again, his lollipops.
* [[spoiler:YouCantGoHomeAgain]]

[[folder:Other Non-Combatants]]
'''Misaki Aoyagi'''
->Voiced by: Creator/WakanaYamazaki
* AbusiveParents: She was shown to have been unstable before Seimei's death, but that was what really pushed her over the edge.
* FreudianExcuse: It's implied that she was abused herself, not that it excuses her behavior.
* TheOphelia: A very unstable and violent version.
* YouShouldHaveDiedInstead: To Ritsuka, among the many other abuses she heaps on him.

'''Hitomi Shinonome (Shinonome-sensei)'''
->Voiced by: Creator/MamikoNoto
* ChristmasCake: {{Deconstructed}}. Not only is she unmarried, but also a virgin... and it shows since [[CatGirl she still has her cat ears.]] Her self-esteem takes a nosedive because of this. Though technically she's not Christmas Cake, since she's only 23.
* {{Meganekko}}
* PsychologistTeacher: She tries.
* ShrinkingViolet

'''Zero (male)'''
->Natsuo voiced by: Creator/MitsukiSaiga\\
Youji voiced by: Creator/HiroyukiYoshino
Natsuo Sagan (fighter) and Youji Sagan (sacrifice.)
* ArtificialHuman
* BadLiar: Youji is one, apparently because he thinks it's pointless. When Natsuo skips school he has to come up with an excuse and fails miserably. Even Yuiko almost caught on. Contrast to Natsuo's ConsummateLiar.
* {{CatBoy}}s
* CreepyTwins: By their actions. They aren't actual twins.
* ConsummateLiar: Natsuo is stated to be one by Youji. Apparently he always keeps a straight face and even Youji can't tell when he is or isn't lying. This contrasts nicely with Youji who [[BadLiar couldn't tell a lie to save his life.]]
* DontYouDarePityMe: Something of Natsuo's initial reaction to Soubi's kindness before Soubi outright [[spoiler:asked Natsuo (and Youji) to live with him]].
* EyeScream: [[spoiler:When Natsuo was little, he accidentally put his right eye out.]]
* FeelNoPain: Or temperature, as Soubi realizes...
* [[spoiler:[[NewTransferStudent New Transfer Students]]: In chapter 85.]]
* [[JerkWithAHeartOfGold Jerks With Hearts Of Gold]]: They really can be the nicest people one could ever meet - especially Natsuo. Not that this stops them from being blunt, rude, or sarcastic when they feel like being such.
* NeverTellMeTheOdds: When they head out to [[spoiler:confront Seimei]], Nagisa tells them they'll be murdered because they aren't strong enough. They go anyway (and with Ritsu's approval), and not only do they come back alive, but if Ritsuka hadn't burst into the library when he did, they probably would have gotten somewhere, considering [[spoiler:Seimei reacted to Natsuo saying he would control his name]].
* ReplacementGoldfish: Youji, for [[spoiler:Nagisa's sister]].
* TookALevelInBadass: Natsuo.
* TurnCoat

'''Zero (female)'''
->Kouya voiced by: Creator/RieKugimiya\\
Yamato voiced by: Creator/YumiKakazu
Kouya Sakagami (fighter) and Yamato Nakano (sacrifice.)
* ArtificialHuman
* {{Catgirl}}s: Before they lose their ears to each other.
* DrivenToSuicide: [[spoiler: Subverted at the last minute.]]
* FeelNoPain: [[spoiler:Initially for Yamato.]]
* FriendlyEnemy: Yamato meets Ritsuka for lunch [[spoiler:and inadvertently reveals that she can feel pain.]]
* SchoolgirlLesbians
* [[spoiler:ScrewDestiny]]: Their ultimate decision.

[[folder:Septimal Moon]]
'''Nagisa Sagan'''
->Voiced by: Creator/SanaeKobayashi
* [[{{Manchild}} Womanchild]]: Lampshaded by Youji, who says that you'd never guess she's over 30.
* ElegantGothicLolita
* MoralDissonance: [[spoiler: She knows that Ritsu raped Soubi when the latter was a child, and while she's disgusted by it she hates ''Soubi'' for it. Most likely due to the fact that she's in love with Ritsu.]]
* {{Tsundere}}
* TheUnfavorite: Exhibited by her towards Sacrifices; she absolutely ''hates'' Sacrifices. The only exception to this rule being Youji [[spoiler: who looks like her dead little sister]].

'''Ritsu Minami'''
->Voiced by: Creator/TakehitoKoyasu
* BespectacledBastardBoyfriend: To Soubi
* DepravedBisexual: Debatable. [[spoiler:He loved Soubi's mother and was furious when she married another man, and seemed to have no problem sexually abusing Soubi in her place. Like many real life child sexual abusers, his abuse of Soubi had more to do with control than actual physical attraction, since he says "Be dominated" to Soubi, before his usual routine of hitting Soubi with a whip under the guise of "training." While it seems while he wanted control and power over Soubi, there are hints lying around that he does genuinely care for him. That training may have been both to protect him ''and'' to have power over him.]]
* [[spoiler:EyeScream]]
* ManipulativeBastard: Soubi at least seems to believe he's this.
* NiceHat: His character in Wisdom Resurrection wears one, then a new one later on.
* NobleDemon: He's done horrible things. That isn't going to stop him from trying to pick a fight with someone who has done ''worse'' horrible things. [[spoiler:He also can't stand Seimei for having wronged Soubi. In fact, it comes out as more of a personal grudge, but he can't stand the fact that Seimei "completely ruined Soubi".]] Not to say this excuses his past behavior nor some of his present behavior, but he's not entirely all that bad.
--->'''Ritsu''': You can't get angry if you don't care deeply.
* NotInThisForYourRevolution

->Voiced by: Creator/AyaHisakawa
* ACupAngst
* {{Hikikomori}}
* OtakuSurrogate
* SevenIsNana
* TenMinuteRetirement: Turns into her [[TookALevelInBadass taking a level in badass]].
* TookALevelInBadass
