The main female character and a second-year student at the Tristain Academy of Magic... with a terrible track record in practical magic, thus earning her the runic name "Louise the Zero" for her lack of success rate and elemental attributes. Her presence is mostly based on being the third (and youngest) daughter of the aristocratic La Vallière family, who runs north-eastern Tristain. On a summoning ritual, she accidentally calls upon ordinary Japanese boy Saito Hiraga, and her life will never be the same again. Louise's hobbies are weaving and horseback riding; she is terrible at the former and exceptionally good at the latter.
Can't Act Perverted Toward a Love Interest: Since she only sees Saito as her servant, she has no problem changing in front of him at first. Later, she starts hiding in a closet to change, showing that she thinks of him differently.
Clingy Jealous Girl: She hates it if Saito's looking or even thinking about another girl. In fact, she can't stand Saito being separated from her for too long, even if he's hanging out with his guy friends.
Covert Pervert: Especially in the novels. Whenever we are shown her fantasies, it's rather... saucy.
Driven by Envy: Tabitha deduced her feelings for Saito are the most effective way to recharge Louise... and decided that jealousy was both the most effective and the easiest to provoke. It worked surprisingly well, although poor Saito would beg to differ.
Even the Girls Want Her: Has found herself in yuri-tastic situations more than once and has been subjected to lots of Marshmallow Hell from other girls, and was kissed by a lot of girls as much as she was kissed by Saito.
Hair-Trigger Temper: God help you if you were the one who caused her temper to blow. That means you, Saito. Ironically, no matter who causes her temper to snap, Saito or any Villain of the Day would be on the receiving end. Saito receives it 99.99% of the time.
Hidden Heart of Gold: She has those moments where she shows some kindness to Saito and is more open to her feelings for him (in a painfully adorable way). Season 4 ditches the 'hidden' part because she makes it clear to him and everyone else around that she loves him. And guess who gets married to who in the Grand Finale...
Lima Syndrome: She ends up falling in love with the guy that she basically kidnapped and enslaved.
Love Makes You Crazy: Very much so. Her obsession with Saito will cause her to beat him if he so much as looks at another woman. And when he (occasionally) gets angry and leaves she ends up hardly able to leave her bed.
Magical Girlfriend: Can be seeing as one, since she brings to her world taking him away from his boring life. However, she does this by basically kidnapping and enslaving him.
Nominal Hero: Louise has very little if any altruistic impulses early on before Character Development sets in. The defining moment in her maturity is probably when Louise throws aside her noble rank to come to Tabitha's rescue.
Older Than She Looks: Looks about ten (not helped by her chest) is actually around 16 by our world's years by the start of the series.
Tsundere: Type A. She often acts haughty and demanding to Saito, physically abuses him and has trouble expressing how much she cares about him. Her jealousy when she sees him with other girls is quickly and easily expressed.
Whip It Good: When punishing Saito. It's funny at first, but gets more and more disturbing as the series goes on, especially when she switches out her riding crop for a huge-ass spiked whip. She would eventually give up the whip, as a sign of her overcoming her insecurity with regards to her love relationship, but that would not happen until very late in the novels. She regains it whenever she tries to 'train' Saito to act and look presentable.
Zettai Ryouiki: Somewhere between Grade A and Grade B. Hers isused to be the trope page picture.
Saito Chevalier de Hiraga (Gandalfr, later also Lifdrasil)
Saito is a Japanese boy who, while picking up his laptop after attempting to get it repaired in Akihabara, gets sucked into a portal and into Tristain. As a Familiar he was treated as more of a servant-dog by Louise, although as time passed he came to love her and decided to protect her at all costs.
Almighty Janitor: He was a peasant for quite some time, yet more powerful than most nobles.
Attempted Rape: Saito has a bad habit of expressing his love for Louise physically, and at the worst possible times, when she doesn't want it. The worst instance is in the second novel where he tries to rape Louise because he assumes that she wants to have sex no matter how many times she says no. He begins to make moves on a sleeping Louise, hugging her and kissing her cheek, before moving to lift her dress, which is when Louise wakes up. He confronts her with the idea that she loves him when she demands an explanation, and she vigorously denies it, no matter how much he insists. Finally he moves to kiss her, and she responds violently. At worst its an Attempted Rape, at best it's Saito massively overestimating the level of their relationship, and subsequently making a move. While she had been giving him somewhat mixed signals prior to this and continues to do so for much of the series, he still comes out looking pretty bad, though it's eventually shown that it wasn't entirely by free will.
Brainwashed: It's implied that the reason he stays with Louise in spite of her abusive treatment is that his familiar runes subtly Mind Rape him, making him forget the bonds he has with his family and old world and, over time, replace them with a desire to serve and protect his master. It takes importance in the light novels, where the Mind Rape from the contract is undone and Saito gets all the feelings of homesickness back in a large burst and complicates his relationship with Louise.
Chivalrous Pervert: More chivalrous in the light novels, more perverted in the anime. This is pretty justified; he's a Nice Guy, but he's also a 17-year-old human male. It doesn't even help that in the anime (and, to a lesser extent, even the light novels) Siesta developed a somewhat sadistic streak, sexually harassing him knowing well she's going to get him tortured.
Comedic Sociopathy: A lot of Saito's perverted actions, which on occasion borderlines as Black Comedy Rape, tends to be shrugged off by some fans unlike Louise's abuse. And there was the one time he definitely was asking to get beaten half to death when he tried to rape her while she was asleep. This ends up being explained as a side effect of the process of becoming a familiar; Saito is unknowingly being urged to do something to form a more concrete connection with his master as well as his runes "conditioning" him into servility causing him to act fearless along with other compulsive behavior even though he's scared out of his wits and/or wouldn't have done them normally.
Cool Loser: Initially shunned as a peasant, he gained a slight grudging respect through various achievements, but really took the cake after holding back an army of 70,000, and subsequently becoming a Chevalier Knight.
Crazy Jealous Guy: While he's not as violent about it as Louise, he has shown to be very jealous whenever other guys flirt with her.
Flanderization: Saito becomes increasingly perverted as the anime goes on.
Flash Step: He's described as moving so quickly you can only hear footsteps.
Girl on Girl Is Hot: He got amused at the sight of Louise and Tiffania groping each other in the women's bath. Also, he got turned on when he saw Montmorency and Beatrice kiss while under the influence of the Love Potion.
Happily Married: To Louise in the Grand Finale. It is hinted that their wedding took place in the same chapel where they got wed in Season 2's finale. The epilogue shows Louise using the World Door spell and the two go to Japan so Louise can see our world and meet Saito's parents. Counts a Crowning Moment of Heartwarming.
Happiness in Slavery: Louise basically enslaved him and treats him like dirt, but he still loves her and stays by her side.
The Hero: Ironically he's made a Vice-Captain in Season 3, making him Guiche's Lancer.
Idiot Ball: There are so many freaking times where Saito could've easily avoided Louise's wrath by simply explaining the situation in clear terms. Then again, knowing Louise, even if he does explain his side...
Instant Expert: Justified; being the reincarnation of Gandlafr, he is gifted with the skill to use any weapon he touches. But only as long as it's meant to be a weapon in the anime.
Derflingher is an ancient talking sword which Saito and Louise bought in a local blacksmith in order to make Saito look more intimidating. He and Saito struck up an immediate friendship and have been partners in battle ever since.
A maid at the academy. She has a crush on Saito, and unlike Louise she treats him very kindly. She fell in love with Saito because he stood up for the rights of the people who can't use magic. Recently, she seems to not mind Saito getting punished because she ends up taking care of him anyways. In Season 3, she is appointed by Henrietta to be Saito's personal maid. (It's a long story.)
Adaptation Expansion: Of the rather unsavory kind. In the anime, Siesta appears in many situations and events that originally, in the novels, she was no part of; this comes off with Siesta scheming and getting on Louise and Saito's way much more than usual.
Be a Whore to Get Your Man: She is originally a kind and gentle maid, but falling in love with Saito makes her push herself too much.
Big Breast Pride: After the first season she becomes very boastful about her large breasts due to Saito's preference for large breasts and her rival Louise being flat chested. She frequently brags about her large breasts to Louise and her favorite seduction technique is to let, and in some cases force Saito to touch her breasts.
Bitch in Sheep's Clothing: Has shades of this later on in the story. She often joins Louise in beating Saito if he does something to anger her, and on more than one occasion has attempted to seduce him knowing full well that Louise would beat the living hell out of him for it.
Character Exaggeration: Though appearing in events she was no part of originally, in the anime Siesta comes off as very clingy and ready to get on Louise and Saito's way at every given opportunity.
Clingy Jealous Girl: Starts to display this trope once Tiffania shows up, and shares Louise's utter contempt for the poor half-elf girl.
Covert Pervert: As the anime progressed, she has shown signs of enjoying Louise torturing Saito, going as far as to sexually seduce him, inciting Louise's wrath in return. Seasons 3 & 4 make no attempt to hide this; she's enjoying Saito getting beaten just so she'd be the one to take care of him.
This actually makes Louise Genre Savvy for keeping her away from Saito.
The well-loved Crown Princess of Tristain and Louise's old friend. She eventually ascends to Queen of Tristain. She has a strong sense of justice and strictly obeys her morals, but based on her interactions with Louise and her budding attraction for Saito, this wasn't always the case in the past. She is a Water mage.
Adaptation Dye-Job: Her hair is described as being a chestnut brown in the novels. In the anime her hair is a light purple and in the manga her hair is a much darker shade of purple.
Bitch in Sheep's Clothing: Season 4, Episode 6 shows that she has this kind of personality, telling Louise that she's in love with Saito and then taunting her and her poor, flat chest. Turns out she's been quite one since childhood. Not that it sticks for long.
Politically-Active Princess: She's very active politically. At one point she hires Saito and Loise to spy on a village to confirm her suspicions about corruption within the nobility, because she doesn't trust the usual sources. She was crowned and became Queen after taking command of the royal guard and leading them into battle to defend Tristain.
Reasonable Authority Figure: She doesn't throw her weight around just because she can, tries to take care of her troops in war, and will even abide by rules set by the school at a party.
Royals Who Actually Do Something: She takes command of the army when needed, and even tries to stop Louise and Saito's group from rescuing Tabitha partly out of her concern for their safety, and partly because she doesn't want to provoke another war by making it seem like she approved of their invasion into another country to rescue her.
Ship Tease: Constantly with Saito. It ultimately goes no where.
It returns again in Season 4, and she isn't afraid of telling to Louise's face that she loves him.
Captain of Tristain's Royal Musketeers in service of Henrietta. She is introduced in the second season. She holds a strong animosity towards Fire mages because of her past. Since she appears stern and uninterested in men, many people think or assume that she is a lesbian.
Ambiguously Lesbian: She has no qualms silencing Louise by kissing her when the latter gasps while eavesdropping on a pair of conspirators. She's only visibly mortified in the anime. In the novel she shrugged it off as no big deal and later had a big laugh about it at Louse's expense.
And Then What?: Colbert tries this tactic to talk her out of revenge but she brushes it off with ease. Once she acomplishes her revenge, she's going to fight for her queen until she dies.
Badass Normal: In a world filled with mages, she holds her own with a pistol and a saber.
Bystander Syndrome: Even if Saito approaches her to save him from another misunderstanding-fueled temper tantrum by Louise, she does nothing to help him.
Celibate Heroine: She has no interest in romance, be it with Saito, any other man, or any woman.
Demoted to Extra: Doesn't have much role in Season 3 other than being Henrietta's bodyguard. She does have her moment when she finds out that Colbert is still alive. She spares him in the end, out of the fear that his students will hate her.
She has even smaller role in Season 4. To the point that all of her screen times last for about 5-30 seconds and she doesn't even speak in some of them.
Does Not Like Magic: She doesn't like mages, especially Fire Mages, due to a group of such Mages burning her native D'Angleterre.
Revenge: Her motivation — her native D'Angleterre was set ablaze by a group of Fire Mages, supposedly to contain an epidemic. One such Mage was Colbert, who, unknown to her, backed out at the last minute due to his doubts concerning the epidemic, and eventually rescued her from the blaze.
A priest-knight from the Holy Empire of Romaglia sent as transferee to Tristain Magic Academy. Julio is sent by the Pope as a support for Henrietta's expedition to Albion, now in political strife after the fall of the royal family and then followed by the death of Reconquista's leader, Cromwell.
The Ace: Julio is infuriatingly good at absolutely everything. This is justified to a degree, as he's also a Void familiar with more control over his magic than Louise; his primary ability is to control magical creatures.
Ambiguously Bi: Julio is canonically in love with Louise but may or may not also have an interest in her boyfriend Saito as shown when he tells Saito whether jokingly or not that he loves him and wants to kiss him as well as Louise.
The Beastmaster: Has his dragon tamed despite the fact that he isn't a mage.
Foreshadowing: She was capable of reviving Saito without any magical artefacts (Ring of Andvari being one), by filling him with magical energy (and thus sacrificing her memento). Later, the powers Saito gained upon becoming Lifdrasil made him into a container for magical power, with added ability to unleash it as destructive spells (on command of his master), or revive himself by using some of it.
Love Epiphany: Although she always seemed to admire Saito, she seems to start developing feelings for him after he defends her during her inquisition trial, and in the beginning of Season 4 outright wonders about those feelings she has when Saito is around.
Louise's classmate and a Fire Mage, whose power is drawn from her strong passion for money. Her family has an intense dislike for the La Vallieres, and thus treats Louise with disdain. She flirts and has dated (and heavily implied in the anime to have slept with) many of the Academy's male students, but falls in love with Saito. Her familiar is a giant flame-tailed salamander she creatively calls "Flame".
Bi the Way: While she is very much fond of Saito and Colbert, she starts to have a thing for Louise in the third season. Taken to extreme in the light novels.
Cool Loser: Initially shunned by socialites at the academy and subjected to slut-shaming and public humiliation, because of her "popularity". It stopped once she returned the favor and revealed herself to be a triangle-class Fire Mage.
Lovable Alpha Bitch: Starts off the series as a bully towards Louise, but becomes nicer as the series continue. By this time, she doesn't act rude anymore and often ends up being the gang's big damn hero along with either Tabitha or Mr. Colbert.
Pet the Dog: After learning of Tabitha's Dark and Troubled Past and seeing her haunted by nightmares in her sleep, she decides to lie beside Tabitha and embrace her, telling her everything will be alright.
Louise's classmate and a consummate playboy despite being in love with Montmorency. He always carries an artificial rose with him, the stem of which is his wand. He also likes to dote upon his familiar, a giant mole named Verdandi. As his familiar indicates, his specialty is earth magic and he prefers to fight using bronze statues called Valkyries. He is named after Antoine V de Gramont, Duke of Guiche, a French military figure.
Chick Magnet: He is and should be one, but the moment other girls (usually Montmorency) end up seeing or knowing about him two-timing or committing perverse acts (which is... a lot of times) he'd better say goodbye to his pride... and three years of his life.
Jerk with a Heart of Gold: Once one gets past his overwhelming narcissism, Guiche is actually a nicer guy. By season three, he and Saito are actually good friends. In the light novels, too, when Saito was presumed dead, Guiche erected a statue of him in honor of his friend. Unfortunately, Louise and Siesta accidentally destroyed it...
The Lancer: Is typically Saito's go-to-guy whenever he's in need of assistance. Ironically, Saito is the Vice Captain of Guiche's knight unit, the Ondine Knights, while Guiche is leader. No one really cares and they seem to treat Saito as the leader more than Guiche. Guiche doesn't mind much, though.
Spell My Name with an S: His familiar Verdandi is named after the Norn of the Present from Norse Mythology. Some fansubs made incorrect variations, either out of ignorance of the source material or immediate associations with Belldandy of Ah! My Goddess, whose original name is the same as that of the source material but was fallen victim to Dub Name Change when the said series was exported to America.
The soft-spoken, book-reading best friend of Kirche and classmate of Louise with a mysterious past. She specializes in Wind Magic and has a dragon familiar named Sylphid. Apparently has a younger sister named Irukuku but as it turns out, Irukuku is also Sylphid who is a Rhyme Dragon capable of using nature magic and transforming into a human.
Broken Bird: She was the Crown Princess of Gallia, whose father, the Duke of Orléans, was killed in a succession dispute with his older brother Joseph, who then became King. Her mother was driven insane after taking a drugged drink meant for Charlotte, and she was sent to dangerous missions as a means to distance her from the Gallian throne and hopefully have her killed in the line of duty. Her mother gets better in Season 4.
Cool Loser: Never even tried to be socially accepted, yet still manages to be cool in her own way.
Hopeless Suitor: She doesn't start falling for Saito till the very end of Season 3 after he goes out of his way to rescue her from her uncle. She does fruitlessly try to woo him at points in Season 4, and in one incident, even tells Louise that if they got into another fight, she would simply throw her rank as queen around and forcefully marry him.
An Ice Person: Being a Triangle Mage with a Wind specialty, she's adept at creating blizzards and icicle javelins.
Rei Ayanami Expy: She shares Rei Ayanami's appearance and traits (light blue hair, quiet and stoic).
Rescue Romance: Begins to like Saito a lot after he goes out of his way to rescue her despite her attempts at attacking him earlier. She even goes so far as to defend him against some of Louise's jealousy fueled spells/explosions.
Not So Stoic: Her feelings do peek through once in a while, especially whenever she remembers her family, or when she fell in love with Saito late in season 3. Hoo boy, she takes this trope to higher levels in Season 4, though..
A girl in Louise's class and Guiche's on-and-off girlfriend. She is a Water Mage with a frog familiar known as Robin. Her family makes oaths to the water spirits of Lake Lagdorian. She is one of the few girls in the series who never actually falls in love with Saito, instead becoming friends and teammates with him.
The daughter of a viceroy who served under Tiffania's father the archduke, Matilda was forced to flee her home with Tiffania after King Wales murdered the rest of their families and had her home burnt to the ground. These events caused her to develop a burning hatred of nobility, and forced her into a life of crime to pay the bills. At the start of the series she is posing as a secretary at the Tristain Academy of Magic with the intent to eventually steal the Staff of Destruction (an M72 LAW) stored there.
Mr. Colbert is a teacher at the Academy and one of the first mages to respect Saito. He dislikes war and instead tries to find ways to adapt fire magic for technology. He's quite absent-minded but dedicated to his job and deeply interested in the culture of Saito's world, especially the machinery which are much more modern than Halkegenia's.
Wardes is the captain of Tristain's Griffin Knights and Louise's fiancé. His runic name is 'Lightning'. When Louise is sent on mission for Princess Henrietta, Henrietta sents him with Louise to help and guard her. He is polite and a gentleman, but tends to get carried away whenever her wants something done. He is the assassin of Albion's prince, Prince Wales.
Bastard Boyfriend: Played with, he was Louise's fiance, but once she dumps him, he quickly reveals the bastard part.
Joseph is the King of Gallia, a Void Mage and has the "Mind of God" Sheffield as his familiar. Outwardly he plays the facade of being just a pretty boy that cannot rule his country if his life depended on it, while in reality he is a ruthless politician and schemer. There was no act he would hesitate to do, or anything he was not willing to sacrifice due to the 'Void' in his heart. He is the uncle of Tabitha.
Lack of Empathy: Seems to have no issues killing his brother, then attempting to poison his niece, and later killing not only Romalia's men, but his own as well in an attempt to feel some kind of emotion. Season 4 implies that Joseph's actions were attempts to make him feel regret for killing his younger brother, but in a twisted way.
The father of Louise, as well as Eleanor and Cattleya, he is extremely protective of her and would do whatever it takes to ensure her safety. He is married to Duchess Karin Desiree of Tristain. The Grand Finale shows him bringing his youngest daughter to meet his future son-in-law at the altar. He looks genuinely happy for them.
Overprotective Dad: Was willing to kill Saito for almost having sex with Louise. In the light novel, after Saito's promotion, he still kicks his ass for trying to make moves on Louise. The Grand Finale shows him bringing his youngest daughter to meet Saito at the altar. He looks genuinely happy for them.
Papa Wolf: While he does have his overprotective tendencies, he does genuinely care for Louise and even willing to oppose the state if it tries to exploit her talents like a tool.
The mother of Louise, Eleanor and Cattleya, she is also known by her nickname "Heavy Wind" and was the former Commander of Manticore Corps, though during her time as Commander she hid her gender. She was the strongest Wind magic-user ever to serve in the Tristain military according to records. The Grand Finale shows her attend Louise and Saito's wedding. She looks genuinely happy for them.
Cattleya Yvette La Baume Le Blanc de La Fontaine is Louise’s second sister. She believes Louise has potential, and that she is a wonderful girl. More than anything, she longs for Louise’s happiness, and is fine with the fact that Louise has feelings for a peasant. She is a kindhearted person, and even helped Louise escape from her house to go back to the Academy. She knows Louise well, and could easily tell that Louise was in love with Saito, even when Louise denied it. Although Cattleya is older than Louise, she isn't married due to the fact she is ill. The Grand Finale shows her attend Louise and Saito's wedding. She is with her parents and Eleanore and is genuinely happy for the couple. Cattleya is an Earth mage.
Knight Templar Big Sister: Though lesser than Eleanor's, she is definitely this. Her character song with Cattleya and Louise (Nemurenai Fantasy) shows this, along with hints of her approval of Louise and Saito's relationship.
Eleanore Albertine Le Blanc De La Blois De La Vallière is Louise’s eldest sister and is currently working as head researcher in the Tristainian magic research organisation simply known as the "Academy". She resembles her father more than her mother. Eleanor brought Louise out of the magic academy, intending to find her a noble husband. It should be her turn to get married instead of Louise, and she had gotten engaged to the Earl of Burgundy, though he called off the marriage. Like most the rest of Louise’s family, except for Cattleya, she believes that Louise is incapable of performing magic, and that she is a zero. The Grand Finale shows her attend Louise and Saito's wedding. She looks annoyed at first, possibly for the fact that the youngest Vallière daughter got married first, but she immediately loses the frown and is genuinely happy for them.
Knight Templar Big Sister: She's willing to lock Louise up so she wouldn't go to war. Her character song with Cattleya and Louise (Nemurenai Fantasy) shows this, along with hints of her secret approval of Louise and Saito's relationship.
Meganekko: When we get to see here dere side, she becomes this.
One of the teachers at the Academy. He believes that the wind element is the most powerful out of all the elements and wasn't afraid to prove it, or at least he did until Jean Colbert the Flame Snake put him in his place. To date he only appears in the novels.
