!!! Voiced by: Creator/SaekoChiba (JP - anime), Creator/YuiHorie (JP - drama [=CDs=]), Creator/WendeeLee (EN)
* AntiHero: Hilariously done!
%%* BadassAdorable
* BerserkButton: Unfortunately for our hero, she seems to have a lot of them, and pressing one will usually lead to him being messily bludgeoned. Like: accidentally walking in on her while she's getting dressed, accidentally groping her, [[ArsonMurderandJaywalking refusing to have anything to do with a school club she formed...]]
* CloudCuckoolander: Dokuro-land, population: 1.
* {{Expy}}: Of sorts to [[Manga/{{Doraemon}} Doraemon]], as pointed by various references through the series. She comes from the future to prevent Sakura from turning out bad much like how Doraemon did for Nobita, but for twistedly nonsensical reasons.
* GenkiGirl: ''Extremely'' genki.
* GirlishPigtails
* GoKartingWithBowser: Frequently hangs out with Sabato.
* GreenEyes
* HairTriggerTemper: Gets angry very easily and at the slightest provocation, and usually deals with it by killing Sakura [[TheManyDeathsOfYou in many different ways]].
* HeroicComedicSociopath: She runs rampant with this.
* HolyHalo
* {{Irony}}: The reason she was sent from the future? To assassinate Sakura, in order to prevent him inventing a device that will make females stop aging.
* KarmaHoudini: Practically the living incarnation of this trope, as she never once gets comeuppance for her cruelty towards Sakura.
* LovingBully: UpToEleven. All those acts of violence, torture and death she inflicts on Sakura are how she expresses her love for him.
* MagicalGirl
* MagicalGirlfriend: A DeconstructedCharacterArchetype
* ManicPixieDreamGirl: Perhaps a little ''too'' manic...
* NamesToRunAwayFromReallyFast: "Bludgeoning Angel." Moreso for the literal translation, "Club-To-Death Angel."
* OurAngelsAreDifferent
* PervertRevengeMode: Dokuro kills Sakura whenever he does anything perverted.
* YouGottaHaveBlueHair: It's a light purple in the first season, [[HairColorDissonance but a light blue in the second]] - the same shade as her sister's.
* ZettaiRyouiki

!! Sakura Kusakabe

* AccidentalPervert: Sakura almost never has any overt sexual thoughts when he provokes Dokuro's wrath. In fact, these moments are just about the only time he ISN'T having sexual thoughts.
* AndIMustScream: It's mentioned in the novel that Sakura actually remains conscious whenever Dokuro splatters him.
* BackFromTheDead: [[DeathIsCheap Repeatedly.]] Seriously, this guy is the anime equivalent of [[WesternAnimation/SouthPark Kenny]].
* ButtMonkey: ''Everything'' is out to get this poor schmuck.
* [[CherryBlossomGirl Cherry Blossom Guy]]
** GenderBlenderName: His name is typically used as a girl's name in Japan.
* TheChewToy
* CosmicPlaything
* TheDulcineaEffect: He's always willing to help Sabato, despite how often she's tried to kill him.
* MajorInjuryUnderreaction: Comes to act like this once being blown up with a club becomes a mundane occurence.
* TheManyDeathsOfYou: He gets offed by Douro in various different ways.
* NiceGuy: Grows fond of Dokuro despite how she treats him and brings food to the homeless Sabato when she's not looking, since she's not a bad person either and he feels sorry about her having to be stuck in the past unless she could kill him.
* TheyKilledKenny: OnceAnEpisode. Sometimes even more than once.
* UnluckyEverydude: One ought to have pity on Sakura. Not only is he saddled with a girly name, he's targeted by celestial forces, and he's costantly and painfully killed and revived ad nauseum.

%%* BadassAdorable
* [[BigLittleBrother Big Little Sister]]: To Dokuro.
* EyepatchOfPower
* GagBoobs: Particularly noticeable while wearing a swimsuit.
* HolyHalo
* ImprobableWeaponUser: Her WeaponOfChoice is a [[ClothFu wet towel]], named Eckelsax.
* LadyOfWar: She's a very elegant fighter, in spite of the wet towel.
* NiceHat
* YamatoNadeshiko: She's very soft-spoken and polite.
* YouGottaHaveBlueHair
* YoungerThanTheyLook: Despite being the tallest of the main cast, as well as having [[Film/MontyPythonAndTheHolyGrail huge tracts of land]], she's ''nine years old.''

!! Sabato Mihashigo
!!! Voiced by: Creator/RieKugimiya (JP), Creator/LauraBailey (EN)
* AntiVillain: Type IV.
* ButtMonkey: She has it ''even worse'' than Sakura. At least he has a roof over his head -- she lives in a box under a bridge!
* ElectricTorture: Inflicts this with her weapon, Durandal, which by her account is capable of frying a ''blue whale.''
* ElegantGothicLolita: In the first manga, she wears this outfit for some reason during her introduction.
* GoKartingWithBowser: Frequently hangs out with Dokuro.
* HolyHalo
* HornedHumanoid
* IllGirl: Frequently, particularly in season two. It's mostly just a cold, but it's exacerbated by her less-than-ideal living conditions. Like just about everything else in this show, though, this is PlayedForLaughs.
* PurpleEyes
* SchoolUniformsAreTheNewBlack

* {{Foil}}: Arguably one to Dokuro.
* GirlishPigtails
* GirlNextDoor
* NiceGirl: The only person who is always on Sakura's side, believing him to be a good person.
