* Casca is the only woman in the Band of the Hawk from ''{{Manga/Berserk}}'' and mainly serves as Griffith's NumberTwo. She's quite respected by pretty much the entire band, at least some of whom refer to her as "anego" (sister). In time, she becomes the {{Love Interest|s}} of Guts. When the Eclipse goes down, [[spoiler:she becomes the victim of a horrific BreakTheCutie ordeal, culminating in her rape at the hands of Femto right in front of Guts]]. Two years after the horror, she and Guts form the core of a new group of TrueCompanions later on, which is [[GenderEqualEnsemble evenly split between]] four guys (Guts, Serpico, Isidro and Puck) and four girls (herself, Farnese, Schierke and Evarella).
* In ''{{Anime/Beyblade}}'', there no teams with more than one girl.
** The ''Bladebreakers'' add Hiromi/Hilary to their team in the second season, but not as a beyblader.
** ''Team WHO''/the ''Dark Bladers'', the ''Majectics'' and ''Neo Borg/Demolition Boys/Blitzkrieg Boys'' avert the principle by not even having female members.
** ''Team Psykick'' has multiple groups within it, but still only one female beyblader.
** The pure two-man-teams, ''King & Queen'' and ''F-sangre/F-Dinasty'', technically avert this trope, since two people isn't enough to count for the Principle.
* ''{{Manga/Bleach}}'' has LoadsAndLoadsOfCharacters, and among the many {{ensembles}} only the Espada and Privaron Espada follow this trope.
* In ''Manga/DeathNote'':
** Out of the many {{Shinigami}} to appear in the story, only Rem was revealed as explicitly female. Due to their unusual shapes, explicit declarations of male/female would be needed to determine genders, but enough others were declared male that it's easy to assume if the gender wasn't explicit, it was male, making Rem the only female {{Shinigami}} in the whole universe.
** The human cast is predominately male, due to the focus on detectives or high-ranking businesspeople, which are predominantly male groups in real-life Japan. In the Kira Task Force for the Live Action Film, where WordOfGod states that one female was added simply to avoid an all male team like in the anime.
** Wammy's house had many gifted students, but apparently only one ''female'' student, Linda, who appears very briefly in the manga and not at all in the anime series. [[note]]She ''might'' be in the anime CompilationMovie ''Death Note Relight 2: L's Successors''; the character she's supposed to be is officially unnamed[[/note]]
* ''Anime/DigimonFrontier'' had an evil team of five digimon, as well as a good team of five digidestined (heroic humans) and five digimon. In each of the three groups, only one character was female.
** Because of the fact that Hawkmon is a male Digimon despite Yolei's gender, Gatomon ends up being the only female Digimon of the 2nd generation Digidestined's Digimons.
* ''{{Manga/Eyeshield 21}}'' is about high school boys playing American Football. The only position a female student can have is the manager position. Unusually, as long as a team has a manager, that position is filled by a girl.
* In ''Manga/FairyTail'':
** Most guilds, especially the Dark Guilds and {{Quirky Miniboss Squad}}s, have just one [[TwoGirlsToATeam (to two)]] female members.
** Of the [[ArcNumber seven]] dragon slayers introduced, only one is female.
* ''Manga/FistOfTheNorthStar'' only had one female fighter in the manga and that was the village guardian Mamiya.
* In ''Manga/FullmetalAlchemist'':
** Riza Hawkeye is the only woman in Roy Mustang's group of Amestris Military, which consists of roughly eight men.
** Amoung the four known generals of the Amestris Military, Olivier Mira Armstrong is the only female, and her staff consists of only men.
** Among the... let's say seven... homunculi, Lust is the only female (though Envy is genderless according to WordOfGod).
* In ''Manga/GhostInTheShell'', the only woman in Sector 9 is Major Motoko Kusanagi, and she is TheLeader of seven men, not counting Tachikomas. Justified due to the fact that, while speculative fiction, it preserves the country's real world issues. Sexism in the government is dealt with explicitly in the adaption, ''Anime/GhostInTheShellStandAloneComplex'', and is a major catalyst for many of the political issues encountered later. Given this attitude, it's not unthinkable that an Elite government operations unit would have difficulty maintaining women not hyper-competent.
* In ''Manga/KatekyoHitmanReborn'', there is only one female, Chrome Dokuro of the Mist, amongst Tsuna's six Guardians. {{Subverted|Trope}}, since [[spoiler: the real Mist Guardian is [[MasterOfIllusion Mukuro Rokudo]], and Chrome is a [[SealedBadassInACan vessel for him]]. Meaning instead of one woman, there's half a woman. Less than a woman. The illusion of a woman.]]
* While there are many female characters in the main and supporting cast of ''LightNovel/LogHorizon'', there is only one female member (Marielle of the Crescent Moon Alliance) out of the 11 members in the Round Table Council, the player-run government of Akihabara. This is a result of the major guilds in Akihabara mostly having male guild masters.
* In the ''Franchise/LupinIII'' franchise, there are five recurring characters, and Fujiko is the only recurring female character. Even ''she'' was originally only a series of several one-shot characters, as a {{homage}} to ''Film/JamesBond''.
* The director of ''Manga/MaiHiME'' claimed in an interview that he deliberately wanted to invert this trope. Indeed, the important male cast is considerably smaller than that of the female cast. But considering that this a MagicalGirl team show, the effort's [[ImprobablyFemaleCast kinda misapplied]].
* ''Anime/MazingerZ'':
** Sayaka Yumi is the only female (with 8 guys) at the Photon Lab Institute.
** The six villains under Dr. Hell are all male. Baron Ashura is also female. Or half-male and half-female. Cyborgs.
* ''{{Manga/Naruto}}'' mostly utilizes teams of 3, following TwoGuysAndAGirl most of the time, but {{ensembles}} of five or more also exist with single female examples:
** There is one female among the five Jonin senseis.
** There is one female among the Sound Five, Tayuya.
** There is only one female among the thirteen Akatsuki, Konan.
** Various movie and filler villain parties also tend towards a single female member.
** Of the five Kages in Shippuden only Mei Terumi is female.
*** This trend continued in the epilogue where [[spoiler:Akatsuchi]] is the only female Kage.
* ''Manga/OnePiece''
** Luffy's crew, the Straw Hats, begin at five members, including Nami, their navigator. After East Blue, they add four more members, [[TwoGirlsToATeam including another female,]] Nico Robin.
** One of the eleven Supernovas is female, "Big Eater" Jewelry Bonney.
** One of the "Seven" Warlords of the Sea is female; "Pirate Empress" Boa Hancock.
* ''Roleplay/RecordOfLodossWar'':
** The novels start with a typical fantasy adventuring group of six, which is mostly male. The sole female main character is a blond elf named Deedlit (keep in mind that this series was based on an actual TabletopGames campaign played by a bunch of Japanese college fraternity brothers in the late Seventies -- women didn't always fit well into hack'n'slash scenarios).
** The sequel ''Chronicles of the Heroic Knight'' averts with a "new generation" of heroes. The party consists of three (or four) male and three female characters.
* In ''Anime/SaintSeiyaOmega'', Aquila Yuna is the only girl among the six Bronze Saints.
* ''Anime/ScienceNinjaTeamGatchaman'' (and its various CutAndPasteTranslation including ''Anime/BattleOfThePlanets'' and ''G-Force: Guardians of Space'') has one heroine in a squad of five heroes. Partly justified in that they are fundamentally an elite military unit.
* In ''Manga/TanteiGakuenQ'', Minami Megumi is the only female student in the five-person Q-class, and her role is mostly limited to memorising and recollecting scenes with her photographic memory.
* In ''{{Manga/Toriko}}'', Lady Chiyo is the only female in the eleven members of Gourmet Corp.
* ''Anime/SpaceBattleshipYamato'' has -- you guessed it -- one heroine in a crew of eight.
* ''{{Anime/Voltron}}'' (''Golion'') also has one heroine in a squad of five heroes. Princess Allura originally only joined the team as a replacement after one member of the all-male FiveManBand was killed. Even then, it was over everyone else's objections, and only because they couldn't form the Giant Robot without a fifth member.
