* AllLovingHeroine
* AnguishedDeclarationOfLove
* AnimalMotifs: Is nicknamed "Arinko-chan"/"Antsy" by Sergey (and in Zwei, Mahya) because her GirlishPigtails resemble antennae, and because the "ari" in her name means "ant" in Japanese.

* BettyAndVeronica: Betty to Nina's Veronica.

* DirtyOldMan: In some of the extras.

* ExpressiveHair: Her hair does odd stuff like twisting into hearts.
* {{Expy}}: Arika is friendly like Mai, perky like Mikoto, and also [[spoiler:reminds Miyu of Alyssa]].

* GenerationXerox: It turns out that she's most like [[spoiler:her mother's charge, Sifr, in terms of personality and her dream of being an Otome]].

* PluckyGirl
* PossessionImpliesMastery: It's not instant, but she's able to figure out how to use the Coral Robe's various abilities during her first Materialization.

* PrecociousCrush: On Sergey, but she eventually gets over it.

* RedHerring: [[spoiler:A reveal says that she's the real lost princess of Windblum, though she quickly assumes that to be a mistake. Turns out she was right.]]

!!Mashiro Blanc de Windbloom
->'''VoiceActor:''' Creator/{{Yukana}} (JP), Katie Rowan (EN)
->'''Otome:''' Arika Yumemiya, [[spoiler:Nina Wáng]]
The princess (soon queen) of the Kingdom of Windbloom. At first, Mashiro is rebellious and quite unenthusiastic about the responsibilities of her job, and [[spoiler:may not actually be the real heir to the kingdom, if rumors are to be believed]]. Through a series of (unfortunate?) events, she becomes Arika's Master.
* AwesomeMomentOfCrowning: ''Very'' early on, in episode three.
* AscendedExtra: Mashiro in ''Anime/MaiHime'' was merely a supporting character and the school director. Now she's a princess and one of the main three.

* BerserkButton: Arika finds out that referring to her as a "[[spoiler:fake princess]]" is one.
* BreakTheCutie: As part of her CharacterDevelopment.
* BreakTheHaughty: Her character arc in a nutshell.

* CrossPoppingVeins: Featured image on the page, even.
* DistressedDamsel
* DontYouDarePityMe
* EverythingsBetterWithPrincesses
* {{Expy}}: Of ''Anime/MaiHime''[='s=] Mashiro Kazahana.
* GodSaveUsFromTheQueen: Prior to her character development, while not villainous a example, her growing up a spoiled princess has led to doing little more than abuse her power. [[spoiler: The fact that she was hated by everyone but her maid Aoi and her incompetent reign allowed Nagi to pull off his plan (which led to her people hating her even more) leads to her getting out of this.]]
* GratuitousFrench: In her name.
* GreenEyes
* HeroicBSOD: Briefly, after she realizes just how much her people hate her when they [[spoiler:[[DisneyDeath kill Aoi]], her caretaker, right in front of her out of hatred for the queen. Don't worry, Aoi Gets Better]].
* IdenticalGrandson: If the opening scene of ''Anime/MaiOtomeZwei'' is right, Mashiro looks [[spoiler:exactly like the queen of Windbloom from the time Fumi became the first Otome. It's thus possible that those who passed her off as the real princess did so while invoking this trope!]]
* KingIncognito: Starting with her first appearance. Apparently she runs around Windbloom all the time in commoner's clothes and no one even notices she's the queen.
* LonelyRichKid: Up until Arika's arrival
* MeaningfulName: Mashiro Blanc de Windbloom is an {{Expy}} of Mashiro Kazahana from ''Anime/MaiHime''. Kazahana literally means "wind bloom", and the kanji can be also alternatively be read as "Fuuka".
* NamedAfterSomebodyFamous: Named after the first Otome, Fumi's, GEM, the Pure White Diamond (Mashiro Kongouseki).
* NobleFugitive: After the MoodWhiplash WhamEpisode.
* OddCouple: With Arika.
* TheOjou: And also [[spoiler:NonRoyalPrincess]]...which is the same trope, really.
* ParentalAbandonment: Both the previous king and queen were killed fourteen years ago. [[spoiler: Since she's really just a random baby the home secretary found and claimed was Princess Mashiro, she's never known her real parents, either.]]
* PrideBeforeAFall
* RebelliousPrincess
* RedOniBlueOni: Blue to Arika's red.
* RequisiteRoyalRegalia: Particularly her signet ring.
* RoyalBrat: Mashiro before...
* RoyalsWhoActuallyDoSomething: Mashiro ''after''.
* {{Tsundere}}: Mainly toward Arika, often outwardly denying feelings of concern for her.
* TwoActStructure: Mashiro's character description can be pretty neatly divided into "pre-CharacterDevelopment" and "post-CharacterDevelopment."
* WellExcuseMePrincess

* GuileHero: When she isn't being TheAce, she's [[spoiler: setting Tomoe up for a BreakTheHaughty HumiliationConga]].

* EmbarrassingNickname: 'The Tragic Meister'. She hates the name.
* FirstNameBasis: With Natsuki and Mikoto. Technically, she calls everyone by their first name, she's just that friendly, but she uses [[UsefulNotes/JapaneseHonorifics honorifics]] in nearly all cases ''except'' with Natsuki and Mikoto. They in turn use only her first name without honorifics as well.
* TheDitz: She's a LOT more lax and easy-going than one would expect from someone of her standing, to the point that she goes on a walk to sort out a tough decision and she ends up walking into a hidden valley dozens of miles from Garderobe.
* GenerationXerox: Shizuru draws the parallel of Arika's and Nina's 'relationship' with Mai and Natsuki's back in their school days. She even had someone else sponsor her tuition to Garderobe just like Arika.

* ShroudedInMyth: Legend says is that she disappeared in the forest split between her boyfriend and her status as an Otome. Turns out that the guy people thought she was with was someone she was only casually acquainted with, and she was split between becoming a Meister for her sponsor family and staying as one of the Five Columns. She decided to talk a walk to clear her head and the rest is history...
* SpotlightStealingSquad: Averted. [[WMG/MaiOtome Fans speculate]] that Mai's greatly-reduced role in ''Otome'' was due to Sunrise wanting to avoid a repeat of what happened with Kira in ''Anime/MobileSuitGundamSEEDDestiny''.
** And again in Zwei. As one of the strongest remaining Otome, she materializes and heads up to fight the enemy that's been causing havoc all this time but is interrupted by a ressurected, old fan favorite so that Akira and a returning friend can deal with the enemy themselves.
* SupremeChef: Mikoto won't eat anything not prepared by Mai. The cafeteria at Garderobe serves 'Tokiha Mushroom Soup', one of her original creations from when she was a student.

* TheCorruption: Somehow, the original [=HiME's=] power got corrupted and memories replaced. Turns out [[spoiler:that the resurrected [=HiME=] were just altered copies based off the originals data.]]
* TheDreaded: The [=HiME=] were called "The Beautiful Devils of Darkness" and several times, people had tried to resurrect them in bids to take over the world.

* {{Reincarnation}}: This one is a bit confusing. Turns out that Mai [[spoiler:who was the [=HiME=] of old, had her power corrupted somehow. The King and Queen of Windbloom who gave birth to Mashiro were the reincarnations of Mai and Yuuichi years later.]]

In the anime, Miyu is a mysterious drifter who pops up from time to time to protect Arika. Her allegiance and motives are largely unknown. It is, however, known that she is very old, at least older than any human currently alive; she has a lot of unexplained knowledge about the world and the Otome technology, which [[spoiler:she uses in the climax]]. She also once knew Arika's ancestor, who is implied to be [[spoiler:Alyssa Searrs; this could possibly mean -- and it is a popular fan theory -- that she is the same Miyu as in ''Anime/MaiHime'']].

In the manga, Miyu has been excavated and brought into working condition by Alyssa, who hopes to replace the Otomes with the "Maids" so that her sister will not have to be headmaster any longer.

* BigSisterWorship: Oh, my yes.
* CheerfulChild
* TheGlomp: Very first thing she does to Natsuki, the very first time they're on-panel together.
* PingPongNaivete: Switches from cool, genius Aries representative to attention-hungry baby sister without missing a beat. And the thing is, neither one of them is an act.

* {{Meganekko}}
* ReasonableAuthorityFigure

* CurbStompBattle: [[spoiler:Manshiro vs. Dark Mai]]
* EvilCounterpart
* {{Malaproper}}: Dark Yukino. She and Dark Haruka appear to have reversed roles compared to their counterparts.
* MythologyGag: Although this is based off of the ''Manga/MaiHime'' manga, in which Shizuru is not a Hime, Shizuru wonders what her own counterpart would be like, and conjures up an image of herself from the ''[=Mai-HiME=]'' anime, complete with GlowingEyesOfDoom and a MartialArtsHeadband with "Natsuki Love" on it.
* NaughtyNuns: Dark Yukariko has an extremely revealing outfit
* PsychoLesbian: Dark Yukino and Dark Haruka.

* AvengingTheVillain
* BaitAndSwitchBoss
* {{Bifauxnen}}
* BigBrotherAttraction[=/=]BigBrotherWorship: She clearly thought Nagi was a far more awesome person than he really was and held him in awe, which is fine and even sort of cute. But she also explicitly described him as her [[BrotherSisterIncest 'ideal lover' and said her 'body yearned for him']], which is [[{{Squick}} less cute]].
* DefrostingIceQueen: Began as a SmugSnake to rival her brother, ended as a Type-A {{Tsundere}}.
* FatherIWantToMarryMyBrother: Though she kept it up well after she realized the implications.
* HeelFaceTurn

* UnwittingPawn: A pair of thieves had infiltrated her staff and used her as their tool to get into Garderoube.
* VillainousCrossdresser: At first. She drops the crossdressing around the same time she drops the villainy.
