!! Dokuro Mitsukai
!!! Voiced by: SaekoChiba (JP - anime), Creator/YuiHorie (JP - drama [=CDs=]), Creator/WendeeLee (EN)
* AntiHero: Hilariously done!
* {{Badass}}
** BadassAdorable[=/=]CuteBruiser
* 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.
* GenkiGirl: ''Extremely'' genki.
* GirlishPigtails
* GoKartingWithBowser: Frequently hangs out with Sabato.
* GreenEyes
* HeroicComedicSociopath: She runs rampant with this.
* HolyHalo
* {{Irony}}: The reason she was sent from the future? [[spoiler: To assassinate Sakura, in order to prevent him inventing a device that will make females stop aging.]]
* MagicalGirl
* MagicalGirlfriend: A DeconstructedCharacterArchetype
* ManicPixieDreamGirl: Perhaps a little ''too'' manic...
* NamesToRunAwayFromReallyFast: "Bludgeoning Angel." Moreso for the literal translation, "Club-To-Death Angel."
* OurAngelsAreDifferent
* PervertRevengeMode: When Dokuro kills Sakura, more often than not, this trope is to blame.
* YouGottaHaveBlueHair: It's a light purple in the first season, but a light blue in the second - the same shade as her sister's.
* ZettaiRyouiki

!! Sakura Kusakabe
!!! Voiced by: ReikoTakagi (JP), Creator/JohnnyYongBosch (EN)
* 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.
* BackFromTheDead: [[DeathIsCheap Repeatedly.]] ( seriously, this guy is the anime equivalent of [[WesternAnimation/SouthPark Kenny]] . )
* BrownEyes
* 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.
* {{Lolicon}}: Apparently. According to Dokuro and Sabato, he will even go as far as to invent a device that will cause all females to stop aging after they turn twelve years old.
* NiceGuy
* TheyKilledKenny: OnceAnEpisode. Sometimes even more than once.
* UnluckyEverydude

!! Zakuro Mitsukai
!!! Voiced by: Creator/AkenoWatanabe (JP), Creator/DorothyEliasFahn (EN)
* {{Badass}}
** BadassAdorable
* 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.
* BlondesAreEvil: Her first few appearances. She gets better as time goes on, though.
* 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.''
* GoKartingWithBowser: Frequently hangs out with Dokuro.
* HolyHalo
* HornedHumanoid
* IllGirl: Frequently, particularly in season two. It's mostly just a cold, but her living conditions don't help. Like just about everything else in this show, though, this is PlayedForLaughs.
* PurpleEyes
* SchoolUniformsAreTheNewBlack

!!Shizuki Minakami
!!! Voiced by: Creator/AyakoKawasumi (JP), Creator/MelaLee (EN)
* {{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.
