The focal character of the main series. Arika is a traveler from the faraway nation of Galelia, who arrived in the kingdom of Windbloom to enroll at Garderobe Academy for clues to the whereabouts of her Missing Mom. She was given the "Azure Sky Sapphire" Gem, which becomes the key to realizing her dream of becoming an Otome. Arika is the daughter of Lena Sayers, the previous Azure Sky Sapphire and Otome to the previous king of Windbloom.
Animal Motifs: Is nicknamed "Arinko-chan"/"Antsy" by Sergey (and in Zwei, Mahya) because her Girlish Pigtails resemble antennae.
"I'm not an ant! I'm Arika!"
Badass Abnormal: She was already faster than Nina, a student Otome, in the first episode, and fought against a Slave before she manifested any powers whatsoever. Then she got nanomachines.
Battle Butler - All Meister Otome are, but Arika in particular is Mashiro's.
Chaste Hero -> Celibate Hero: Knows hardly anything about love despite developing feelings for Sergay. After they end up on opposite sides, Arika gives up on pursuing him and commits herself to being an Otome.
Country Mouse - Quite unfamiliar with many aspects of city life.
Early-Bird Cameo: In the last scene of Mai-HiME's final episode, she runs on-screen from the left as Mai, Mikoto and Natsuki are walking away, then looks at the screen for a few seconds before running off again.
Expressive Hair: Her hair does odd stuff like twisting into hearts.
Expy: Arika is friendly like Mai, perky like Mikoto, and also reminds Miyu of Alyssa.
Generation Xerox: It turns out that she's most like her mother's charge, Sifr, in terms of personality and her dream of being an Otome. Her rivalry with Nina is noted as being similar to Shizuru and Haruka's rivalry, and Mai and Natsuki's, although it has more tragic results than either.
Possession Implies Mastery - It's not instant, but she's able to figure out how to use the Coral Robe's various abilities during her first Materialization.
The Knights Who Say Squee - She was searching for the academy anyway, but she wanted to become an Otome after watching Shizuru fight.
The Power of Friendship: A firm believer in this. Nina notes that her relationship with Mashiro is closer to being friends than master and Otome, and their getting along enables Arika to use Materialize Zwei.
Super Mode: Materialize Zwei, which unlocks the full potential of the Azure Sky Sapphire.
10-Minute Retirement - While dealing with the emotional strain of Erstin's death, she declares she no longer wants to be an Otome and runs off, but decides to return after she talks with Mashiro and they escape from a desert monster together.
GEM: Coral, Ultimate Black Diamond, Neptune Emerald / (manga) Azure Sky Sapphire, Black Smoke Chrysoberyl
Master: Nagi Dai Artài, Mashiro Blanc de Windbloom (in Zwei)
Nina is the top-ranked Coral student at Garderobe Academy, a training ground for Otome candidates. She is not happy with Arika's sudden arrival, but learns to put up with her for the time being. Nina is the adoptive daughter of Major Sergay Wáng of Artài (anime only; in the manga, the two are not related). In truth, Nina is the real long-missing Princess Mashiro of Windbloom, though she doesn't know.
Broken Bird - By the end. She is bearing the weight of her guilt over killing Erstin and her other deeds in Nagi's service, and her father Sergay is on the brink of death, kept alive only by her operating the Harmonium.
Daddy's Girl - Initially seems like a straightforward example of a girl who wants to please her father, but as time goes by, it's revealed that there's quite a bit more to it, as she is in lovewith him.
Dark is Evil: Her Ultimate Black Diamond, according to the character guide, is representative of her “extreme and mostly selfish” love for Sergay, which is antithetical to the Otomes' selfless devotion to their masters.
Fallen Heroine: She tried so hard, and fell so far...so, so far.
Fallen Princess - The real Princess Mashiro and the rightful heir to Windbloom.
For Want of a Nail: In the manga, she is not Sergay's daughter, and thus consistently remains loyal to the heroes. It helps that Nagi is not the main antagonist this time.
One-Winged Angel: In the final battle with Arika, transforms and loses control of herself.
Paint It Black: Nina's post-Face Heel Turn uniform looks exactly like her old one, except with a darker color scheme. Her Transformation Sequence even shows a black shadow, signifying her new "evil" status.
Parental Abandonment - Nina is an orphan Sergay adopted who is the daughter of the previous Queen and King of Windbloom.
Parental Incest - What she'd like to have happen. It almost does toward the end of the series, but Sergay doesn't go through with it.
Perpetual Frowner - To the point where she looks hilariously constipated half the time.
The princess (soon queen) of the Kingdom of Windbloom. At first, Mashiro is rebellious and quite unenthusiastic about the responsibilities of her job, and 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.
Ascended Extra - Mashiro in Mai-HiME was merely a supporting character and the school director. Now she's a princess and one of the main three.
Batman Can Breathe in Space - In Zwei, is able to fly with Arika over the planet despite not even being Materialized, though it's possible that Arika had something to do with it.
Character Development: Begins the series as a bratty princess, then has her throne snatched out from under her, and is forced to rebuild her reputation from the ground up, a job she later takes on with pride.
Heroic BSOD - Briefly, after she realizes just how much her people hate her when they kill Aoi, her caretaker, right in front of her out of hatred for the queen. Don't worry, Aoi Gets Better.
Identical Grandson - If the opening scene of Mai-Otome Zwei is right, Mashiro looks exactly like the queen of Windbloom from the time Fumi became the first Otome. So much for her being a Fake Queen!
King Incognito - 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.
On the other hand, Mashiro Kazahana was an Older than They Look semi-immortal reincarnation, so its possible that when the Hime incarnation was younger, they were more alike. In fact the Obsidian Prince remarks at one point "why are the masters of Kagutsuchi always so difficult?"
Parental Abandonment - Both the previous king and queen were killed fourteen years ago. 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.
Erstin is one of Arika and Nina's friends and roommates on campus. She is unusually gentle and meek, and tries not to hurt anyone. Unfortunately for her, Erstin belongs to a family who follows the Schwarz (no, not that Schwarz), and is turned against the ones she loves, resulting in her death in the anime.
Blackmail: In the manga, it's implied she did this, as it's noted that she had some leverage to use on Natsuki when negotiating to move back into Nina's room, which happens immediately after she learns Manshiro is male.
Heroic Sacrifice: (anime) Block's Nina's attack with her slave to stop her from attacking Arika (despite the fact that Schwarz is on Nagi's side), costing her her life (manga) Tries to do this with a grenade to stop Dark Hime Natsuki, but fails and survives.
The Messiah: She'll die for her friends without a second thought, and thinks nothing of herself. Which makes her betrayal even more tragic.
Schoolgirl Lesbians: Manga!Erstin's crush on Nina is made obvious from the very start. May also apply to her anime incarnation, depending on one's interpretation of her last letter to Nina. She also acts this way among her other schoolmates, and in the sound dramas, admits to having a crush on her Onee-sama Akane, while under the influence of a mushroom that removes her inhibitions.
Irina is the fourth member of Arika's initial Four Girl Ensemble, and she is fond of engineering and scientific endeavors. She was invited to Garderobe on a scholarship from her home country of Aries. Her closest friends on campus are Erstin and Professor Youko.
Expy: Irina looks a bit like Yukino, who appears in this series as her home country's president.
Tomoe is the second-ranked Coral student in Garderobe Academy. Unlike her fellow Otome peers, she is willing to use every dirty trick in the book to maintain her status, and makes it clear on a few occasions that she dislikes everybody (with one exception, and only one: Shizuru, whom she's had a crush on since she was a youngster). After Schwarz assumes control over the school, she is contracted into joining Nagi's special Valkyrie squadron.
Anime Hair: Long hair on her right and short on her left.
Bitch in Sheep's Clothing: She puts on a polite front when people other than Arika and Miya are around, and even sticks up for Arika on a few points (including during her scheme to frame Arika for selling her uniform) in order to maintain it.
Chewing the Scenery: Normally, Tomoe speaks in a calm manner, but does a lot more shouting after her defection and subsequent reunion with Arika.
Demoted to Extra: In the manga, only appears a few times alongside other generic students, and is not evil.
Devil in Plain Sight: Subtlety is not one of Tomoe's strong points, but yet only Chie and Shizuru are aware of her true motives.
Evil Costume Switch: Following the Schwarz invasion, Tomoe ditches her Coral Robe for a suit of transforming all-black fighter-jet armor, complete with Spikes of Villainy and a mean spear.
Karma Houdini: For all she has done, she survives her Disney Villain Death, and according to Zwei she apparently didn't get any punishment beyond having to leave the academy.
Kick the Dog: Forcing Shizuru to sleep with her to guarantee Natsuki's safety. (Even though being "forced" was what Shizuru wanted in the first place.)
Les Collaborateurs: Joins the Valkyrie squad along with a few other Corals after being promised promotion to Meister status.
Precocious Crush: Has had a crush on Shizuru since she was a young girl and Shizuru was a Pearl Otome.
Scarpia Ultimatum: To Shizuru, by falsely claiming that Natsuki has been captured, too.
Villainous Breakdown: After learning that Shizuru was merely pretending to have feelings for her, and seeing Chie and the Aswad intervene to protect Arika.
Yandere: Tomoe wants Shizuru, and is perfectly willing to kill anyone whom she considers "in the way"leading her to attack and attempt to murder Arika, even though Shizuru lavishes a majority of her attention on Natsuki.
Miya is a member of the Coral class, along with Arika, Nina and Tomoe. She gets used by Tomoe as an accomplice for some of the former's most heinous actions, despite her own personal objections. Unable to stand up to her, she is forced out of Garderobe when Tomoe forces her to take full responsibility for attempting to have Arika raped.
Beware the Nice Ones: In the manga, once she finds out that Kazuya is a Schwarz agent and he’s been cheating on her, she activates her robe and takes him down.
Cat Girl: Her Meister Robe makes her resemble one.
Love Martyr: In the manga, takes some extreme measures out of loyalty to Kazuya, including temporarily leaving the academy when he goes missing. When she discovers the truth about him, she returns. (By contrast, her anime incarnation's love for Kazuya is requited, and he's equally willing to make sacrifices)
Onee-sama: All three are called this, but Akane exemplifies the character type the most.
Running Gag - Her and Kazu's complete inability to have sex due to all sorts of extenuating circumstances.
Speak Now or Forever Hold Your Peace: Akane ditches her Meister promotion ceremony to run off with her lover, Kazuya in Episode 13. He later becomes her Master after he takes the crown of Cardair following Argos XIV's death.
That Came Out Wrong: In her special, when she and Kazuya are about to have sex.
Kazuya: I'm a little scared.
Akane: Don't worry, I know lots of stuff.
Kazuya: Eh?
Akane': (sheepishly waving hands) No! I didn't mean it like that! I learned lots in school!
Kazuya: (nervous laugh) Ah, right.
Wall of Text: Her talking about everything she went through after Kazuya's disappearance in the manga, complete with "Fast forward" and "skip" buttons shown.
Fake Defector: Temporarily joins the Valkyrie unit to keep an eye on Tomoe, who joined of her own volition. It's believed that she may also have been spying for Aries' army, as Haruka addresses her as "Major" when they meet in combat near the end.
Schoolgirl Lesbians: Chie loves to flirt with some of the girls, and is implied to be in a relationship with Aoi, the royal maid.
Master: Fumi Himeno, Charles Guinel Roy d'Florince VIII
Home country: Cardair
Room attendants: Miya Clochette and Yayoi Alter
Pearl and Trias #3 and a member of the Cardair royal family.
Alpha Bitch: Strongly opposes Arika coming to Garderobe, since she feels she doesn't fit the character of the school as someone without much money or the backing of a nation.
Bitch in Sheep's Clothing: There's a significant contrast between her behavior when the faculty is watching and when they aren't. She even keeps up the facade around most of her fellow students, and keeps her "Spiraling" a closely guarded secret.
Establishing Character Moment: Chiding some of her juniors for gossiping about Nina, then, when she's out of earshot, says she hopes it's the result of her "spiraling" Nina for refusing to be her room attendant.
Improbable Weapon User: Her "maki maki" spiral voodoo magic causes no shortage of nuisances for anyone she tries to curse (Arika is a favorite target of hers). Part of a Running Gag.
Manipulative Bitch: In the manga, she manipulates Erstin into fighting Arika by using her being moved out of Nina's room against her, along with Mind Control.
Pearl Otome #4 and a native of Artài, Nao likes to keep to herself and intends to use her Garderobe education as a way to marry rich and live easy. She is later promoted to the vacant Fourth Column spot by Natsuki during Windbloom's time of crisis, and is unhappy about it. Only Shiho ever calls her by her real first name, while everyone else addresses her as "Nao".
Anti Heroine: Type III. Nao does good deeds in spite of her apathy toward the whole Otome thing.
Brilliant, but Lazy: She keeps her grades high enough to meet Sergay's standards, but doesn't want to become a Trias. Unfortunately for her, after Akane's departure, she has to replace her.
Chinese Girl: Like Nina, she is from Artai, and wears a qipao as her standard outfit as Column IV.
Cool Big Sis: She may not be frank about it, but this universe's Nao cares for her younger classmates.
Senpai Kohai - Nina and Arika, her room attendants and the only two underclassmen with whom she interacts on a regular basis, call her "Nao-senpai" rather than "Nao-onee-sama"
Garderobe Academy Faculty
Fumi Himeno
GEM: Pure White Diamond
Master: Unknown Mashiro look-alike
The first Otome and the founder of Garderobe, as well as its first principal and instructor. It's implied that she eventually retired, married, and had a family, because her body is used as the power source for Garderobe's Predecessor system and produces the school's GE Ms.
Sinister Scythe: In the manga, her statue holds a scythe. Her Dark Hime counterpart also wields one against the heroes.
Stern Teacher: In the manga, tends to penalize Otomes severely for minor mistakes, making it difficult to get the "hearts" required to go up a year.
The Five Columns
Five Otome contracted to the Predecessor, Fumi Himeno, who serve Garderobe itself rather than any individual country. Their right to Materialize off Garderobe property is strictly regulated by a number of treaties and articles. At the start of the series, the position of the Fourth Column is vacant and is later filled by Nao.
Anime-only character. Hailing from Aries, Sara was once a room attendant to Mai during her Coral days, and she, like Yukino, picks up on Haruka's occasional malapropisms. Sara, being one of the Columns, sides with Haruka and the other Alliance members in the finale.
Impossibly Cool Clothes: Sara's costume is extremely outlandish, even by Column standards. She could probably give Lelouch a run for his money...or maybe Batman.
Faux Action Girl: (anime) Even though Natsuki is a Meister-level Otome, she spends much of her time de-powered, delegating actual fighting duties to Shizuru. She loses the very first fight she actually gets involved in due to outside interference, and has to rely on tactics and diplomacy to regain the upper hand.
Show Some Leg: Nao convinces her to try this to flag down a passing Airies transport, then cuts her pants off to do so, leading to them getting arrested for indecent exposure.
Supporting Leader: She's the #2 Column, but is often the one setting up the plans and leading the charge.
Shizuru works alongside Natsuki as her assistant and protector. Her title is the "Bewitching Smile Amethyst", which matches her sometimes flirtatious behavior.
Bodyguard Crush: Her devotion to Natsuki is absolute. Well, okay, not quite absolute, but when Midori asks her why she's fighting for the world, she responds that she fights for a person close to her, and it isn't hard to figure out who it is.
Hypercompetent Sidekick: Played with. She does a lot of heavy lifting for Natsuki and will sometimes go off on her own to do so; but Natsuki is pretty competent herself.
Anime-only character. Mahya is the current Fifth Column. She takes her job very seriously, and tries to keep Akane's libido in check so that she doesn't lose her Otome powers.
Jerkass: Often makes catty remarks, especially to Akane and Kazuya.
Moment Killer: Shows up with several royal guards to drag Kazuya back and arrests Akane after finding the two at a motel, about to have sex. According to Zwei, she does this on a fairly regular basis, rigging a net outside Akane's room to prevent Kazuya from sneaking in to have sex.
One of the Garderobe instructors, Maria is an elderly mother figure and strict disciplinarian who tries her best to teach the students how to honor and respect the Otome traditions, as she once used to be a Meister.
Berserk Button: Does not like disrespectful references to her age.
I Was Quite a Looker: One of the last episodes of the series, and most of the Sifr prequel, showcases a much younger and more attractive Maria (with blond hair!). She says she hides this fact because she "wanted to age gracefully" (no pun intended).
Stern Teacher: In the anime, is typically strict to her students, especially about the harsher aspects of an Otome's life. In the manga, she even carries a riding crop around.
One of the Garderobe instructors, Yukariko is the most visible teacher on campus who is able to remain gentle and calm even under stressful situations.
The Archer: Can fire arrows with forked tips that can pin people down.
Professor Yohko is the school's developer and maintainer of the technology that gives the Otome their powers. She appears to have some sort of past connection with Midori and Rad.
Mai is the so-called "Tragic Meister" who disappeared into the Black Valley a while before her graduation. She is a friend and former rival of Natsuki.
Custom Uniform: Her Pearl and Coral uniforms have orange trim, similar to Arika's pink trim.
Shrouded in Myth: Legend says is that she disappeared in the forest split between her boyfriend and her status as an Otome. Turns out the guy people thought she was with 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.
GEM: Malachite of Pure Love, Abyssal Green Jadeite
Master: Charles Guinel Roy d'Florince VIII
Anime-only character. Rosalie initially resigned from her position due to an Arranged Marriage(that wound up not happening). She initially joins late in the series on the side of Nagi and the Valkyries, but is convinced by Mashiro to switch sides.
Arranged Marriage: The reason she left her post in the first place. She eventually comes back.
Heel Face Turn: Joins Mashiro in stopping the Harmonium after finding out that Nagi has betrayed his allies
Mandatory Unretiremrnt: Forced back into being Florence's Otome after Shiho goes missing.
Shipper on Deck: In a sense; she wants Akane and Kazuya to get married so that Shiho (whom she dislikes) will be able to fill in as the Emperor of Cardair's Otome.
Midori is the leader of the Aswad, who oversees her people from an enclave in a distant mountain area. She is capable of summoning a beast called Gakutenou using a crystal on her glove, but can only do so for a limited time.
Rad is a mysterious Black Knight who serves Midori as her right-hand man. He was involved in the siege of Fuuka Castle 14 years prior to the start of Mai-Otome.
Nagi is the Grand Duke of the nation of Artài and the main antagonist of the show. He is short and sneaky, yet holds absolute command over his subjects.
Affably Evil: In the anime, he's outwardly pleasant to people. Averted in the manga, when he's more willing to openly show cruelty and hostility.
Ungrateful Bastard: In Zwei, he laughs off the failure of several former Artai military officers to secure his release by taking a bus full of hostages, noting that he would have gotten recaptured quickly if he’d stuck with “idiots” like them. Natsuki finds this appalling.
Well-Intentioned Extremist: Nagi says he plans to bring down the Otome system to put an end to using "substitutes" as fighters in wars and take the world out of the pseudo-Medieval Stasis it's been stuck in. That's all well and good, but when those plans include mass murder...
Major Sergay Wáng is Nina's adoptive father, and a messenger from the Duchy of Artài working directly under Nagi. In the manga, however, this isn't the case, as 1) Sergey and Nina aren't related, 2) he and Nagi are enemies, and 3) Sergey, not Nagi, is eventually revealed as the Big Bad (after killing the latter).
My Master, Right or Wrong: Sergay is quite torn about the direction Nagi is going, but remains loyal to him after having done so for so long. However, he ultimately decides Nina is most important for him and tries to destroy the Lena System, only to get shot in the process
Yukino is the president of the nation of Aries, a patriotic republic on good terms with Garderobe. Her Otome is Haruka Armitage.In the manga, she is a police officer for the Windbloom Police, and Haruka's partner.
100% Adoration Rating - The people of Aries adore her, to the point where they laugh at the idea of anyone trying to run against her during elections.
Generic Cuteness - While not ugly, she's certainly not the beauty most of the other characters are.
Voiced by:Ryoka Yuzuki (JP), Lori Barnes-Smith (EN)
GEM: Continental Orb Topaz
Master: Yukino Chrysant
Haruka is the very impulsive Brigadier General of Aries's army, and a former classmate and Unknown Rival of Shizuru. President Yukino Chrysant is her Master.In the manga, she is an Assistant Inspector with the Windbloom police who dislikes Otomes.
Actor Allusion: Haruka's last name and mannerisms are modeled after Naomi Armitage from Armitage III, a role once taken by her Japanese voice actress, Ryoka Yuzuki.
BFG In the manga, has a vehicle mounted weapon that gets upgraded a few times.
Red Oni, Blue Oni - Red to Yukino's blue. Also red to Shizuru's blue when they team up.
The Rival: To Shizuru, although unlike in Mai Hime, they seem to be friends as well as rivals.
Super Strength - To an even greater degree than most Otome, as she is able to toss an airplane into outer space, and in one of the extras, it is revealed that she pushed the Suzushiro to Windbloom when it encountered engine failure.
Zipang
A country to the far east that condemns the use of Otome and prefers to stay out of Otome conflicts. In the manga, Takumi and Akira are from Cardair.
Fiar is the giant-staff-wielding Otome of Cardair. Her Master is Emperor Argos XIV. They are both killed by Midori when the Aswad retaliate against Cardair.
The prince of Cardair and Akane's boyfriend. After Argos' death, he takes the throne. In the manga, he's actually a Schwarz agent who has been cheating on Akane.
Next to Sergey, John Smith is Nagi's most trusted henchman. He is the main developer of much of Schwarz's weapon technology, including the Robes used by the Valkyrie unit.
Killed Off for Real: Once Sergey finds out what's fueling the Valkyrie Robes (it's Lena Sayers' corpse), he gets extremely pissed off and puts two bullets in Smith's head.
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.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. The Dark Hime version of Alyssa is able to exert some authority over Miyu, but ultimately, Alyssa Kruger wins
Mikoto is a chubby black cat who lives in the castle with Mashiro. (Well, not exactly. The cat is actually owned by a humanoid girl who is also named Mikoto, a goddess who lives in the Black Valley. She's Mai's master.)
A painter from Airies who runs against Yukino in the presidential elections, showing up at the site of the busjacking. His running mate and supposed girlfriend is Tomoe Marguerite.
My Nayme Is...: While most of the returning characters except Mai have different last names, his first name has inexplicably been slightly changed.
Ted Baxter: He clearly has no chance against Yukino, but seems to think that he does.
Here We Go Again: Goes up the steps to the academy, and announces her desire to become an Otome even though Natsuki is slowly dismantling the system.
Identical Stranger: Looks like a younger Erstin, which is somewhat disturbing to Nina.
In the Hood: Wears a face-concealing hood until the end of Zwei.
No Name Given: "Ribbon-chan" is her unofficial nickname.
Manga-exclusive characters
Manga-exclusive characters
"Mashiro" (real name unknown)
The de facto main character of the manga series. A twin of the deceased princess Mashiro who is forced to pose as her to avoid panic about the princess' real fate.
If It's You, It's Okay: Both Erstin and, of all people, Nagi are shockingly willing to work past that whole 'has a penis' thing once they find out that the girl they love isn't actually a girl.
Took a Level in Badass: Several levels in badass, actually. He began the series unable to defend himself from school bullies and ended it as a Seraph-armored slayer of world-devouring horrors.
Natsuki's younger sister, a child genius who holds a high position in the Aries government despite her extreme youth. She enters the story while attempting to market a mass-produced version of Miyu that she hopes will replace the Otome system... so her big sister can spend more time with her.
The Glomp: Very first thing she does to Natsuki, the very first time they're on-panel together.
Ping Pong Naïveté: 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.
Manipulative Bastard: Tries to rig a contest in her favor by sending Miyu to seduce the judge. One wonders how an eight-year-old thought up that one...
Saeko Kruger
The president of Aries in the manga, and Natsuki and Alyssa's mother.
The manga incarnation of Sergay, who is essentially completely different from his anime counterpart except for his given name. He is not Nina's father, is the Prime Minister of Windbloom rather than an officer in the Artai military, and also is a very unpleasant person at heart, who becomes the main antagonist and tries to destroy the world, which he believes to be built on lies.
Malaproper: Dark Yukino. She and Dark Haruka appear to have reversed roles compared to their counterparts.
Mythology Gag: Although this is based off of the Mai Hime 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 Glowing Eyes of Doom and a Martial Arts Headband with "Natsuki Love" on it.
Naughty Nuns: Dark Yukariko has an extremely revealing outfit
Villain Override: Dark Alyssa tries this on Miyu, but Alyssa responds that Miyu is her most important person, inspiring Miyu to overcome it and kill Dark Alyssa.
Arashi Dai Artai
The younger twin sister of Nagi, Arashi is the antagonist (sort of) of the manga's pseudo-sequel, Mai-Otome Arashi. Taking over Artai following Nagi's death, Arashi passes herself off as a man and buys out Garderoube's debt as a means of taking over the installation to avenge Nagi's death, which she blames on Mashiro and the Otome.
Rescue Romance: At 'Mashiro'. The obvious problem with seeking revenge against a Chick Magnet with a penchant for playing Big Damn Heroes; if at any point you are endangered during the process, he will save you and you will fall for him.
Unwitting Pawn: A pair of thieves had infiltrated her staff and used her as their tool to get into Garderoube.
Villainous Crossdresser: At first. She drops the crossdressing around the same time she drops the villainy.
The Great Cosmo Beauties (Marie Antoinette and Yang Guifei)
The main antagonists of Mai Otome Arashi, who use Arashi in order to get into Garderobe in an effort to obtain the Azure Sky Sapphire.
