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.
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.
Empowered Badass Normal: 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.
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.
Innocently Insensitive: To Miya, regarding Miya's discovery that her and her best friend's home countries are at the brink of war. This likely makes it easier for Tomoe to manipulate Miya into setting up Arika for Attempted Rape.
In the Blood: Though her natural potential isn't nearly as absurd as her mother's.
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.
Red Herring: 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.
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.
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.
God Save Us from the Queen!: 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. 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.
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. It's thus possible that those who passed her off as the real princess did so while invoking this trope.!
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.
First-year students at Garderobe Academy, Coral Otome all fight using the same Coral Robe. Two are assigned as room attendants to second-year Pearls, who mentor them while they do chores. Only half of all Corals advance to their second year.
Master: Fumi Himeno (manga) Mashiro Blanc de Windbloom
Home country: An Nam
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.
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.
Bait the Dog: While her nasty true personality is well-known enough not to be considered a spoiler, she initially comes off as a friendly, polite and talented Coral.
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.
Blatant Lies: Virtually any scene in which she acts nice to Arika, or anyone else. One scene that sticks out is late in the series, after making some comments mocking Nina's relationship with Sergay, Nina loses her temper and slaps Tomoe hard. Tomoe then claims to Shizuru that she did nothing to deserve this treatment.
Chewing the Scenery: Normally, Tomoe speaks in a calm manner, but does a lot more shouting after her defection and subsequent reunion with Arika.
Clingy Jealous Girl: She hates Arika just for getting attention from Shizuru even though it wasn't even that much
Expy: Essentially a more villainous version of Shizuru from the original series.
It's All About Me: Her only motive is possessing Shizuru and hates so much as giving attention to anybody else. She only works with Nagi since it helps her, she doesn't care about his plans, though she has no problem with the destruction they cause either
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.)
After seeing Miya Taking the Heat for her, for which Miya ultimately gets expelled, she mutters to herself that Miya is worthless.
Les Collaborateurs: Joins the Valkyrie squad along with a few other Corals after being promised promotion to Meister status.
Precision F-Strike: Shortly before her defeat at Arika's hands, she screams, "Stop fucking around, you damn ant!"
Precocious Crush: Has had a crush on Shizuru since she was a young girl and Shizuru was a Pearl Otome.
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.
Reasonable Authority Figure: With the exception of Shiho. Chie sympathizes with Arika for having to face being accused of selling her uniform so early in her time at Garderobe, and she and Akane help find clues to prove Arika's innocence.
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.
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 and Yukino address her as "Major" when they meet 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.
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.
Broke The Rating Scale: She gives Arika and Erstin's "meal" 0 points just by looking at it. When Arika tricks her into swallowing a morsel, she reduces the score to negative 10 points.
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.
Hair-Trigger Temper: In her specials, it's suggested that some of the disasters that happened were the result of her getting angrier and angrier, spiraling more and more each time until she spirals herself.
Japanese Honorifics: Calls most of her year-mates and juniors "-san", in addition to using "-oneesama" on senior Otome, although her tone is not always respectful (for example, she uses "-oneesama" on Rosalie even though they loathe each other). When Rosalie laughs at her when she trips during their confrontation, Shiho screams Rosalie's namewithout honorifics.
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 II. 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.
Dis Motivation: She gets good grades to meet Sergay's expectations, but stays as #4 Pearl to avoid becoming a Trias. Unfortunately for her, Akane's appointment as Florence's Otome and subsequent elopement with Kazuya means that Nao, now third among the remaining Pearls, replaces Akane on the Trias.
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
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 GEMs.
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.
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.
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.
Jerk Ass: 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.
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, and believes those who do not have what it takes should quit. In the manga, she even carries a riding crop around.
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
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.
Devil in Plain Sight: Even for someone who hasn't watched Mai-Hime, it's made pretty obvious that he up to something evil despite the comedic moments he suffers from. Notably, all jokes with his character are dropped after he gets active with his schemes.
A Taste of the Lash (manga): Strikes Nina's backside with a riding crop. He surprisingly likes to be on the receiving end as well.
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. 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.
Meaningful Name - Her name in this continuity is a pun on her name in Mai-Hime, specifically the "Kiku" of "Kikukawa", which is written with the character for chrysanthemum. It also reference her position of power in this series as the chrysanthemum is the symbol of the Japanese Imperial Family.
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.
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 as a decent sized ship into outer space, and in one of the extras, it is revealed that she pushed the Suzushiro (her massive sand-cruiser) to Windbloom when it encountered engine failure.
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.
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 she uses in the climax. She also once knew Arika's ancestor, who is implied to be Alyssa Searrs; this could possibly mean — and it is a popular fan theory — that she is the same Miyu as in Mai-HiME.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.)
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.
Anti-Villain: Type IV. She merely wants to spend more time with her sister, and Arika sympathizes so much that she has trouble committing herself to the battle against Miyu.
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.
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.
