Characters / The Familiar of Zero

Multiple-Character Tropes

• Badass Cape: Capes are a sign of nobility so they're a big deal for nobles, and considering the cast, most of it wears one. Also, they flare out in a very badass manner despite there not being any wind.
  • When Louise renounces her noble status so she can rescue Tabitha from her uncle without involving Tristain in an international incident, she gives Henrietta her cape.
  • When Saito is knighted in the third season, he is given a cape.
• Big Damn Heroes: Kirche and Tabitha quite a bit. Mr. Colbert and Kirche do this in Season 3. Heck, Kirche gets to save everybody at some point in each season.
• Genre Blindness: The Knights of the Water Spirit, for peeking on the girls' baths. Saito tried to stop them, but...
• Overly Long Name: A good way to identify nobles is by the five word or longer full name.
• Took a Level in Badass: Saito, Guiche, and Malicorne are all good examples, especially Malicorne because he was the most useless. All of them develop their skills and mature over the course of the series.

Main Characters

General Tropes

• Battle Couple: Louise and Saito follow the traditional "the Warrior keeps the enemies busy while the Mage casts" structure. They start as just a mage and her familiar, but they become a romantic couple later on.
• Belligerent Sexual Tension: Louise and Saito often butt heads while falling in love, especially in the first season.
• First Kiss: They kiss during their first meeting as part of their contract establishment.
• From Roommates to Romance: After being summoned to another world, Saito is forced to move into the magic academy's dorm and Louise has to share her room with him because she's his master. At first, Louise thinks of Saito as nothing but a familiar and treats him like a pet at best or slave at worst, even making him sleep on a pile of straw instead of a bed. As they spend more time together, they end up falling in love. The series ends with them married.
• Lady and Knight: Louise is the Bright Lady (she matures in the role, eventually) and Saito is her White Knight. He will protect her even if it means standing alone against an army of 70,000 soldiers, archers and mages.
• Magic Contract Romance: The relationship between Louise and Saito begins with their Familiar-Master contract. Their First Kiss was part of the summoning ritual.
• A Match Made in Stockholm: Although it wasn't intentional, Louise pretty much kidnapped Saito when she accidentally summoned him to her world and forced him to become her familiar. The way Louise initially treats Saito borders on enslavement, but they eventually become a couple and even end up married.
• Mistress and Servant Boy: Louise is officially Saito's mistress because he's her familiar. In the beginning, Louise sees Saito as nothing more than her personal servant, even going to the extreme of calling him her dog and treating him far worse than that. Their relationship becomes romantic later on, but it still takes time for Louise to stop treating Saito like a slave.
• Muggle–Mage Romance: Louise is a void mage and Saito is a normal boy from Japan whose only magic comes from their contract.
• Official Couple: The romance between Louise and Saito is the focus of much of the story. The two get married at the end of the light novels and the final anime season.
• Sword and Sorcerer: Louise is the Sorcerer and Saito is the Sword. She summoned him to serve as the physical fighter that would protect her while she casts her spells. Granted, she wasn't expecting a human physical fighter.

Louise

Louise Françoise le Blanc de la Vallière

Voiced by: Rie Kugimiya (JP), Cristina Valenzuela (EN), Annie Rojas (Latin-American Spanish)

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. During 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.

---

• A-Cup Angst: Her complex about her flat chest is a large part of her character as she sees it as one more area she's deficient in, and unfortunately, all but one of her romantic rivals have larger chests than her.
• Adaptational Jerkass: In the light novels, Louise is still an aggressive Tsundere, but she has more Jerk with a Heart of Gold moments and development compared to her anime counterpart. In the anime, she comes off as considerably less sympathetic due to having a nastier temper and her violent tendencies towards Saito being far more exaggerated.
• Adopted into Royalty: After Tabitha's rescue, Louise, who has been stripped of rank by her own family, is adopted as a sister by Henrietta, making her second in line for the throne.
• All of the Other Reindeer: As a result of her inability to use magic she suffered major scorn from her fellow magic wielding nobles, who dubbed her "the zero".
• Almighty Janitor: All other wizards are ranked from Dot to Square based on how many elements they can control. Louise's rank is "zero" and yet she is more powerful than any of them.
• Anti-Hero: She has many personality flaws (short-temper, prone to violence, inferiority complex) but she also has heroic traits, loyally protects her country and eventually matures enough to get her flaws under control.
• Anti-Magic: Dispel is one of her void spells.
• Badass Adorable: The few times she can get her act together, she is as dangerous as she is weapons grade cute.
• Betty and Veronica: In the original, the Veronica to Siesta's Betty because she is a haughty noble, and thus, out of Saito's league. The roles were switched in the anime.
• Big Sister Worship: She idolizes her big sister Cattleya.
• Butt-Monkey: She starts getting as good as she gives in the later chapters of the novel.
• Can't Act Perverted Toward a Love Interest: Since she only sees Saito as her familiar, 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.
• Character Exaggeration: In the anime, Louise has a much shorter fuse when dealing with Saito and his Accidental Pervert moments.
• 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. Considering how crappy her life was before Saito came into it, however, it's understandable.
• Covert Pervert: It's more prominent in the novels. Whenever we are shown her fantasies, it's rather... saucy.
• Curtains Match the Window: Pink hair and eyes.
• Defrosting Ice Queen: She warms up to Saito as time goes on.
• Devoted to You: Despite her constant abusive treatment, Saito is deeply in love with her and will never leave her, even if it is for a chance to go back to his own world. It's implied that Saito's 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. The only confirmed effect was suppression of homesickness, which made Saito less likely to want to leave Louise, rather than rewire him into full subservience, but the experience shook Saito badly enough that he wondered how much of how he felt for her came from him anyways, putting yet another obstacle in their troubled relationship.
• Disproportionate Retribution: Explained further in the novels. She injures Saito enough that even he can't move for some of the smallest things. It's usually cheating on her.
• Domestic Abuse: Explosions an such for Saito, who is first her servant and then her boyfriend. She gets better about this as time goes on.
• Double Standard: Abuse, Female on Male: She tends to physically abuse Saito when she feels he's being a pervert or even looking at other girls, reaching Comedic Sociopathy levels.
• 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 her other considerably stacked contemporaries, and was kissed by girls as many times as she was kissed by Saito.
• First Girl Wins: She's the first girl Saito meets in Halkegenia, his indisputable main Love Interest and the one he ultimately marries.
• Gambling Ruins Lives: Louise gets a Compressed Vice in the form of a descent into gambling addiction in season 3 when the group goes undercover and eventually loses all the crew's money in gambling in the most predictable way (despite Saito's best attempts to stop her, she wagered larger and larger amounts until she finally placed all of their remaining funds on one bet, all without winning a single time). All in one night (after that, she never had that problem or even been seen gambling).
• Glass Cannon: She becomes such after she acquires Void magic, since while void spells are extremely powerful, they also take a long time to cast.
• Godiva Hair: During the bath or hot springs scenes, though there's little to cover up.
• Green-Eyed Monster: 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.
• Groin Attack: Her favored method of dishing out discipline to Saito is a quick shot between the legs.
• Hair Color Dissonance: Her hair color is described as strawberry blonde in the novels, but it looks bright pink in the illustrations.
• Hair-Trigger Temper: God help you if you were the one who caused her temper to blow. Saito receives it most of the time.
• Having a Blast: Her signature spell is Explosion.
• Hidden Heart of Gold: She has those moments where she shows some kindness to Saito and is more open to her feelings for him. Season 4 ditches the 'hidden' part because she makes it clear to him and everyone else around that she loves him. Guess who gets married to who in the Grand Finale...
• Humanizing Tears: She usually cries whenever she drops the Tsundere front and allows herself to be honest about her feelings towards Saito. For a good example, when she thinks him dead, she bawls her eyes out over Saito.
• Hypocrite:
  • Again, it's more prominent in the novel. She's always calling Saito out for being perverted, (even when the comments are directed towards her) yet she's likely just as bad as her familiar.
  • It's also worth mentioning that she claims to hate seeing Saito get hurt, yet she frequently abuses Saito throughout the series.
• I Just Want to Be You: When she became her 'ideal self' during the masquerade ball, she looked exactly like her older sister Cattleya.
• Inept Mage: Subverted — the reason she can't do normal magic is because of her affinity with the Void, the arcane fifth element. At the start of the series, everyone thought the Void was a myth and so assumed she was inept.
• Inferiority Superiority Complex: She's loud about her family status and history because she feels like garbage for lacking magical power. As she develops her Void magic this goes away and her A-Cup Angst becomes more prominent.
• In-Series Nickname: "Louise the Zero"
• Jerk with a Heart of Gold: An abusive, egotistical and nasty person who generally treats people with scorn. She can also be patriotic and a decent friend at times. She tries to emulate her gentle older sister but more often emulates the harsh one. The key word here is "tries" because she easily falls back on bad habits.
• Karma Houdini: She never receives any consequences for abusing Saito, at all... Granted, she does find herself in embarrassing situations, but that isn't really enough to be considered Laser-Guided Karma.
• Lack of Empathy: Initially she has no regards for Saito's feelings because she sees him as a familiar instead of a person. She did better with her fellow nobles and Henrietta.
• Love Makes You Crazy: Her obsession with Saito will cause her to beat him if he so much as looks at another woman. When he (occasionally) gets angry and leaves she ends up hardly able to leave her bed.
• Magical Girlfriend: She can be seeing as one to Saito, since she brings him to her magic world taking away from his world. However, she does this by basically kidnapping and enslaving him.
• Ms. Fanservice: Despite being flat, she has scenes where she is in lingerie.
• My Hero, Zero: She's nicknamed as "Louise the Zero". It signifies both her lack of aptitude in normal magic and her Void powers (considering that the Void, just like the number zero, is the absence of everything).
• Named After Somebody Famous: Louise de La Vallière was a big deal in real life.
• The Napoleon: Her short stature and short fuse are her two most defining characteristics.
• Nominal Hero: Louise has few altruistic impulses early on before Character Development sets in. The defining moment in her maturity is when Louise throws aside her noble rank to come to Tabitha's rescue.
• Older Than She Looks: Looks about ten (her chest is a factor) but she's actually around 16 by our world's years by the start of the series.
• Overly Long Name: Louise Françoise le Blanc de la Vallière.
• Portal Door: The World Door allows her to travel quickly across countries or across worlds. She only has this power in the anime. In the novels, this power is exclusive to the Pope.
• The Power of Love: The most effective way to recharge Louise is to incite emotion, with her feelings for Saito being most effective.
• Power of the Void: Her true magical affinity is the Void... which renders her unable to cast Fire, Water, Air and Earth Magic, the four common types of magic. Her spells have the effect of destroying (explosion) erasing (dispel) or reaching across space (World Door).
• Property of Love: As Saito's master, Louise always refers to him as her possession or dog. She claims he belongs to her only and she can't stand it when anyone tries to take him away from her.
• Psycho Pink: Her hair is bright pink and she's prone to frequent violent outbursts. She can act more mature later on, although she still can get aggressive every now and then.
• Psychosomatic Superpower Outage: Inverted. What recharges her willpower are negative emotions. That's why she was unable to cast her magic when she was really happy that everything was going well.
• Rich Bitch: The main reason she's so stuck up and arrogant is because she's a noble. Downplayed in that it's more akin to a defense mechanism from the frustrations she had to deal with in her life rather than out of actual malice, not that it's apparent at first.
• Royal Blood: Louise is told by Henrietta that her ancestor was an illegitimate child of the King.
• Shameless Fanservice Girl: At first, she has no problem changing in front of Saito, because she considers him to be merely a familiar.
• Squishy Wizard: Saito's primary function in battle is to defend Louise while she completes the long Void chants. She can't handle enemies that get too close to her.
• Stock Light-Novel Calamity Princess: Louise is a bad-tempered, aggressive noblewoman with long pink hair. She's infamously known as "Louise the Zero" for her seemingly poor magic abilities that usually result in explosions, until she's revealed to possess the extremely rare and destructive Void magic. She's also the main love interest in a fantasy harem story.
• Strong Family Resemblance: She looks exactly like her mother did during her younger days.◊
• Stylistic Suck: Her attempts at weaving are dreadful.
• Sympathetic Slave Owner: Though she mistreats and physically abuses Saito at first, she has genuine affection for him. She mellows out to him over time, and they eventually marry.
• Textile Work Is Feminine: Her hobby is knitting.
• Thinking Up Portals: Season Four sees her learn the "World Door" spell. In the final episode, Louise casts it to see Japan with Saito and meet Saito's parents.
• Tiny Tyrannical Girl: She's so short and underdeveloped that she resembles a pre-teen, and lords her "mistress" status over Saito.
• Took a Level in Kindness: In season 4, she's still a harsh Tsundere, but now acknowledges Saito as her boyfriend and is able to befriend her classmates, even her rival Kirche.
• Troubled Abuser: She mistreats Saito in terrible ways. However, she was bullied, and has low self-esteem.
• Tsundere: A textbook Harsh (Tsun) type. She often acts haughty and demanding to Saito, physically abuses him and has trouble expressing how much she cares about him. She can go from berating and yelling at him to kissing him in the matter of seconds. As the series continues, she's more comfortable showing him affection in front of others, but still turns violent at the drop of a hat if she thinks he's getting along too well with other girls. The ending of the last anime season is all about Louise's tsundere-ness over Saito.
• Tsurime Eyes: Her sharp eyes reflect her harsh and haughty personality.
• Unexpected Successor: Louise is a princess, and second in line for the throne.
• Upper-Class Equestrian: Louise is the daughter of an aristocratic family and horseback riding is listed as her special skill.
• Uptown Girl: Louise is a noble while Saito is a commoner and basically her servant.
• Violently Protective Girlfriend: She makes sure Saito stays safe from others.
• When She Smiles: Saito says he feels happy when he sees Louise smile.
• Whip of Dominance: Played With. Louise frequently carries a riding crop with her in order to "discipline" her Familiar Saito to establish her supposed ownership over him, but she mostly uses it when she gets jealous of him getting close to other women so it actually ends up denoting her as being an Insecure Love Interest instead of being dominant. And while the whipping is often Played for Laughs it also comes across as Double Standard: Abuse, Female on Male, especially later when she switches out her riding crop for a huge-ass spiked whip. She eventually gave up on the whip, as a sign of her overcoming her insecurity with regard to her relationship with Saito, although it was brought back one more time when she tried to 'train' Saito to act and look presentable as a nobleman.

Saito

Saito Hiraga

Voiced by: Satoshi Hino (JP), Jonathan Meza (EN), José Ángel Torres (Latin-American Spanish)

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: As a peasant-style familiar, his rank was as low as palace servants if not lower, yet his ability as Gandalfr is more powerful than many of the student nobles. This trope become less pronounced after Henrietta promotes him to royal knight, and thus a nobleman in his own right.
• 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.
• Awesome Moment of Crowning: His knighthood, and in the novels, he's also consecrated as an Imperial Guard Sub-Commander.
• Back from the Dead: At the end of season 2, he was well and truly dead. Then Tiffania used an heirloom to revive him.
• Beyond the Impossible: His familiar contract breaks so many of the established rules that eventually the cast just rolls with it: he's human, he doesn't obey his master, his contract can be negated, re-established, extended to a second mage.... On the other hand, Louise's classmates aren't at all surprised that "the zero" failed to properly cast the summoning spell.
• Bodyguard Crush: As Louise's familiar, Saito is bound to protect her. Later on, he does it willingly because of his personal feelings for her.
• 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.
• Butt-Monkey: Lots of comic abuse comes his way and not just from Louise, although she is the greatest contributor.
• Character Exaggeration: If you read the novel and then watch the anime, Novel Saito is much less perverted.
• Chick Magnet: Saito has attracted most of the female cast in the series. Surprisingly, he was unpopular with girls before the start of the series.
• Chivalrous Pervert: He's a Nice Guy, but he's also a 17-year-old human male. He may be a pervert, but it's obvious that he cares a lot for the girls around him, especially Louise, who in turn does care for him in her own violent way.
• 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.
• Crouching Moron, Hidden Badass: The perverted guy who doesn't know how to keep his foot out of his mouth is also a determined Mage Killer.
• Culture Blind: He's ignorant of anything not related to Japanese culture, like the I Kiss Your Hand gesture.
• Denied Food as Punishment: On the odd occasion that Louise doesn't use her Explosion spell, she denies him dinner.
• Desperately Looking for a Purpose in Life: At the start of the light novels, he goes as far as using online dating simply to spice up his life.
• Determinator: He took on a whole army for Louise.
• Devoted to You: She won't admit it at first, but Louise can't stand being away from Saito. She ends up hardly able to leave her bed when he gets angry at her and leaves. Later, she outright states she has no reason to go on if Saito is not with her.
• Dude, Where's My Respect?: Played with. While Louise rarely shows him respect, he has been publicly honored many times for his heroic deeds.
• Dude, Where's My Reward?: Inverted. He's been rewarded twice when he wasn't seeking one in either case. First with knighthood and then with his own fiefdom.
• Even the Guys Want Him: After his victory over Guiche, Saito becomes popular with the commoners and some nobles in the school, both male and female.
• Familiar: Of Louise. He's unusual in that familiars usually aren't human. He later learns this is standard for Void mages.
• Fish out of Water: He's a guy from early 21st century Japan who got pulled into a fantasy version of Medieval Europe.
• 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.
• Happiness in Slavery: Louise basically enslaved him and treats him like dirt, but he still loves her and stays by her side.
• The Hero Dies: In the last episode of season 2, Saito sacrifices himself to make sure that Henrietta's army can escape. That is, until he is Back from the Dead due to Tiffania's intervention.
• Heroes Prefer Swords: The Derflinger is his standard weapon. He could use any other kind of weapon and his Gandalfr rune would make him skilled with it but he stays with swords.
• Heroic Sacrifice: He takes on an army of 70,000 to facilitate the escape of Louise, Henrietta, and the rest. He got better thanks to Tiffania's magic.
• I Choose to Stay: At the end of season 1, he gives up a chance at going to home to help Louise repel a Reconquestia invasion.
• 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, that this becomes the only explanation.
• Instant Expert: Justified; being the reincarnation of Gandalfr, he is gifted with the skill to use any weapon he touches. In the anime, this only works as long as it's meant to be a weapon.
• Limited Wardrobe: Saito is rarely seen without the original clothes he wore when he was pulled to Halkeginia from Earth, even after he was knighted, where he simply wears a cape over his clothes.
• Lovable Sex Maniac: Especially in the anime, where his lecherousness and perverted antics are taken up to eleven. 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.
• Love Martyr: Louise regularly whips and/or blasts him, but Saito can't help to still have feelings for her and will do anything to protect her. He even faces an army of 70,000 by himself, just so Louise can escape.
• Muggle in Mage Custody: At the beginning of the series, he becomes a familiar (and basically a slave) of Louise. Over time, she mellows out to him.
• Nice Guy: More noticeable in the novels, considering the Character Exaggeration in the anime, which makes him all the more undeserving of Louise's abuse.
• Nice Job Breaking It, Hero: At the end of volume 8 he and Louise are reunited, Siesta says she'll step aside, and he and Louise retire to their bed for the night. Then he proceeds to start wondering if he's dreaming and starts to insult Louise's chest so she'll hit him and he will see if it's a dream making her freak out and hit him, thus about tripling her insecurity complex, and ruining their relationship's chance at becoming official.
• Nosebleed: Even in the novels this is a sign of his perversion.
• One Head Taller: He's about a head taller than Louise, his Tiny Tyrannical Girl of a mistress/girlfriend.
• One-Man Army: It's pretty damn literal, considering the fact that he faced an army of 70,000 men. He incapacitated a lot of them before going down, and when he did, it was because of archers. Everyone that got into sword range was taken out.
• Ordinary High-School Student: He was walking down the street when suddenly he was in the courtyard of a magic school.
• Ridiculously Average Guy: Explained in the light novels. He has such a mundane life he's described as average at EVERYTHING.
• Stepford Smiler: He may have become one due to Louise's unrelenting abuse, as he says with a breezy smile on his face that adapting is all he's good at and he's used to sleeping on the floor.
• Stock Light-Novel Hero: Saito is the Ur-Example of the "Isekai" version of the trope — he is an Ordinary High-School Student that is summoned by accident to a fantasy world. While he is a Nice Guy and somewhat powerful, the Escapist Character aspects of the character are extremely subdued as he is only the Deuteragonist compared to the female lead. In fact, many early isekai protagonists that followed began as Wish-Fulfillment "fan fics" that promoted Saito's role into the spotlight.
• Strong as They Need to Be: Sometimes Saito will be powerful enough that he can take on an entire army and at other times, all it takes is a single skilled mage to give him a lot of trouble in a fight. How strong he is will usually depend on the needs of the plot (and whether or not he has Derflinger with him).
• Subordinate Excuse: Eventually, being Louise's Familiar becomes just an excuse to stay with her.
• Summon Everyman Hero: Averted. Louise wasn't trying to summon an everyman or a hero. She was trying to summon a magical creature like her classmates that would be little more than her pet.
• Supporting Protagonist: He's the "Familiar of Zero" in the title, but he's following Louise around.
• Thou Shalt Not Kill: At least in the Light Novel, Saito fought trying to resist against the 70.000-soldiers army without killing anyone.
• Took a Level in Kindness: In season 4, just like Louise, the "chivalric" part of his Chivalrous Pervert trait makes gains against the latter.
• Trapped in Another World: Due to being "accidentally" summoned by Louise. Later events demonstrate that the boundary between worlds is more porous than he believed.
• Tsurime Eyes: An odd example that goes with his Crouching Moron, Hidden Badass example. These only show up in dangerous situations
• Vitriolic Best Buds: With Julio. They have their disagreements, but become friends as the series goes on.
• What Measure Is a Mook?: Averted. Saito refused to kill any of the 70.000 men-army because Saito does not consider himself a soldier and is not willing to see the lives of allies and enemies as expendable tools.

Derflinger

Derflinger

Voiced by: Tetsuo Gotō (Japanese), Kaiji Tang (English), Arturo Castañeda (Latin-American Spanish)

Derflinger 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.

---

• Cool Sword: A talking sword that, in addition to being well made, can also absorb magic energy.
• Dying Moment of Awesome: Episode 10 of Zero no Tsukaima F where he shatters trying to absorb an attack from the ancient dragon. It turns out he resided in Saito's Gandalfr runes all along, not in the sword itself.
• Eccentric Mentor: Derflinger is always there to provide advice to Saito and to help him grow as a person. He also has a laughing streak and enjoys teasing people.
• Energy Absorption: One of Derflinger's powers is absorbing spells. Higher level spells take longer to absorb.
• Excalibur in the Rust: Looks like a piece of junk but is an awesome sword.
• The Fog of Ages: Derflinger remembers little of his own life, due in large part to his age.
• Really 700 Years Old: Derflinger is about six-thousand years old, and initially, he looked the part.
• Shipper on Deck: For Saito/Louise. He also encourages Saito to perv on other girls.
• Talking Weapon: The hiltguard functions as his mouth..
• Weapon Wields You: Another one of his powers is to take control of his partner's body, but this costs him mana and so he can't do it for long.

Tristain Academy of Magic

Students

Kirche

Kirche Augusta Frederica von Anhalt Zerbst

Voiced by: Nanako Inoue (JP), Lauren Landa (EN), Carla Castañeda (Latin-American Spanish)

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".

---

• Alpha Bitch: In the early parts of the story she was the typical, smug, popular, and talented queen bee of the Academy who had a mean rivalry with the less popular protagonist, and often played an antagonistic role. As she experienced Character Development, she became more of a Lovable Alpha Bitch.
• Ambiguously Brown: She is from "Germania" (implied to be the world's Germany) but her dark skin tone looks like she came from somewhere else.
• Attention Whore: She's very vain and enjoys being the center of attention at the Academy
• Big-Breast Pride: She's proud of her assets and enjoys subjecting others to Marshmallow Hell. She also enjoys taunting her rival Louise about having a "childish body".
• Black Sheep: She's from a noble military family that is very strict, and her carefree and free-spirit demeanor made her an outcast. They attempted to marry her off in an Arranged Marriage, which she narrowly avoided by traveling abroad and getting into a Wizarding School.
• Blue Blood: She's from a noble family in Germania, and has the arrogance and vanity often associated with upper-class nobles.
• Buxom Beauty Standard: She's very well endowed, which attracts the jealousy of some girls and the admiration of many men.
• Custom Uniform of Sexy: Her uniform is significantly less modest in regards to her chest, due to its large Cleavage Window.
• Demoted to Extra: Compared to Season 1, her screen-time is slowly reduced season after season. It's quite possible that this is because she eventually loses interest in Saito (to be fair, it's not like Saito reciprocates her feelings...which is only natural if either side of a relationship isn't interested in the person pining after them) and the role of Louise's rival is taken by Siesta.
• Dude Magnet: She's extremely popular with the male population at the Academy, to the point some girls resent her for it.
• Elemental Hair Colors: She's a fire mage and has red hair.
• Elemental Personalities: She's a fire mage with a loud personality.
• Femme Fatale: Kirche has a special talent for persuasion, as she does not think twice about using her sex appeal to gather secret information, like in Gallia when they tried to gather information on Tabitha's whereabouts. A very small amount of men could resist this persistence, which does not include the academy boys including Saito himself, until after Fouquet's debut.
• Fiery Redhead: She's a redhead with an energetic, passionate and fiery personality.
• Fiery Sensuality: She's a fire mage and has a special talent for using her sexuality to get what she wants. Only a small number of males have the willpower to say no to her. She herself likes to play up that theme
  Kirche: Love and fire are the destinies of the Von Zerbst family. I only wish to burn in flames of love!

• Ironic Name: Her name means "church" and she has a reputation as a slut.
• Ladykiller in Love: She was a Dude Magnet who Really Gets Around but she falls hard for Mr. Colbert later in the story and becomes dedicated to pursuing him.
• Lovable Alpha Bitch: Starts off the series as a bully towards Louise, but becomes nicer as the series continues. 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.
• Morality Pet: Most of her sympathetic moments come from her genuine friendship with Tabitha.
• Ms. Fanservice: Her character is often played for fanservice. She has one of the biggest busts in the main cast and her school uniform is far more revealing compared to the other girls. She also gets a gratuitous Bathtub Scene early in the story.
• Named After Somebody Famous: Sofie Frederike Auguste von Anhalt-Zerbst-Dornburg, maiden name of Catherine the Great, one of the most powerful monarchs of Russia.

• Playing with Fire: She's a mage that specializes with fire magic.
• Porn Stash: In the anime, her family heirloom is one. Which is one of the clues that there are things summoned from the Earth, specifically Japan.
• Proud Beauty: Only a few male characters are unaffected by Kirche's good looks. She knows this and loves to flaunt and use her beauty to get what she wants.
• Really Gets Around: Kirche seems to date a lot of guys and is heavily implied to be promiscuous (One scene in season 1 shows her half-naked, telling a boy outside to "wait an hour later"), though later descriptions suggest that she just likes to string guys along and doesn't actually sleep with any of them. But (barring her Seduction as One-Upmanship scheme) she won't interfere with anyone who's already in a relationship, as she has no intentions to die over another girl's boyfriend.
• Redheads Are Ravishing: The redheaded Kirche is highly attractive, flirtatious, and wears revealing clothing that shows off her big bosom. She naturally attracts the attention of all men around her.
• Red Oni, Blue Oni: Red to best friend Tabitha's blue; high energy, talkative, flirty, with the magic power to match.
• The Rival: Due to having Feuding Families, she's Louise's main rival in the Academy early parts of the story. Eventually, she becomes more of a Friendly Rival.
• Seduction as One-Upmanship: Her attempts to seduce Saitou have more to do with her trying to one-up Louise than any actual romantic feelings for him.

Voiced by: Yuka Inokuchi (JP), Jennifer Alyx (EN), Cecilia Gómez (Latin-American Spanish)

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.

---

• Awesome Moment of Crowning: She becomes Queen of Gallia after Joseph's ultimate defeat.
• Badass Adorable: Introverted, cute, short, and a powerful and strong willed Triangle class mage. She's also a knight.
• Badass Bookworm: She's a capable mage and most often, she can be found reading.
• Bespectacled Cutie: She's a demure and quiet Cute Bookworm who wears glasses.
• Blow You Away: Wind magic is her specialty.

• Breakout Character: She has her own spinoff manga named "Tabitha's Adventures".

• Curtains Match the Window: Her hair and eye colors are both light blue.
• Cute Bookworm: Tabitha is a rather cute and quiet girl who is usually seen reading.
• Cynicism Catalyst: Tabitha was once a lively and optimistic girl with a happy family, but her father's assassination and the ensuing fallout turned her to an Emotionless Girl.
• Dark and Troubled Past: 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 on 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.
• Dope Slap: Sometimes does this with Sylphid when she becomes too annoying.
• Dragon Rider: She can ride her dragon familiar to fly through the sky.

• Emotionless Girl: Of the repressed variety, as a result of the fallout from her father's assassination; there's plenty of emotion that is not expressed.
• Fire/Ice Duo: Becomes the ice to Kirche's ice after the two become best friends.
• Foil: To her best friend Kirche in many ways. Kirche is taller and more physically well-endowed whereas Tabitha is the opposite. Kirche is also much more outgoing and flirtatious with men whereas Tabitha is more of The Stoic. Appearance-wise, Kirche has red hair with dark skin whereas Tabitha possesses blue hair and a much lighter complexion. Their roles in the story also seem to be mirror opposites, as Kirche falls for Saito very early in the series but seems to lose interest in him after the first season, while Tabitha had very little interest in Saito at the beginning of the series but falls for him when the show has reached a much later stage.
• Graceful Loser: In the Grand Finale. We're not entirely sure, but she attends the Official Couple's wedding and looks genuinely happy for them.
• 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 fruitlessly tries 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.
• Icy Blue Eyes: Her blue eyes fit her calm and collected personality. She can use ice magic to boot.
• Love Martyr: She still loves her mother and is very devoted to her, even though she's insane and can't recognize her as her daughter.
• Magic Knight: She's a knight and so she can handle herself in magicless close combat.
• Not So Stoic: Her feelings peek through once in a while, especially whenever she remembers her family, or when she fell in love with Saito late in season 3..
• Only Known by Their Nickname: "Tabitha" isn't her real name; that's the name of the doll her mother gave her. Her real name is Charlotte Helene Orléans.
• Proper Tights with a Skirt: She's a noblewoman who wears white tights, which create one of many contrasts with her less modest best friend.
• The Quiet One: She rarely talks, even to her best friend.
• Red Oni, Blue Oni: Blue to best friend Kirche's red; quiet, cautious, associated magic etc.

• Rescue Romance: She begins to like Saito a lot after he goes out of his way to rescue her despite her attempts at attacking him earlier.
• Shy Blue-Haired Girl: She's an introverted girl with light blue hair, but rather than a Shrinking Violet, she's just quiet and not interested in socializing.
• Stocking Filler: Rarely goes without her white stockings.
• The Stoic: She rarely shows emotion, even in battle.
• Sugar-and-Ice Personality: Despite her quietness and chilly appearance, she's a nice girl.
• Terse Talker: She speaks in short sentences, usually only saying a few words at the most.

Guiche

Guiche de Gramont

Voiced by: Takahiro Sakurai (JP), Nicholas Manelick (EN), Alan Bravo (Latin-American Spanish)

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.

---

• Belligerent Sexual Tension: With Montmorency, his on-and-off girlfriend. Guiche may be a consummate womanizer, and Montmorency a Tsundere Clingy Jealous Girl, but they do love each other.
• Beta Couple: With Montmorency. Their relationship experiences similar ups and downs to Saito/Louise, but to a lesser extent.
• Bishie Sparkle: Often creates sparkles, whether or not he's trying to charm the Girl of the Week.
• The Casanova: In every episode there's a good chance he'll be flirting with a new girl.
• 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.
• Commitment Issues: Despite his love for Montmorency, he can't bring himself to stick to just her and instead has to flirt with the first years.
• Defeat Means Friendship: One the best examples; after their duel early in season 1 he eventually becomes Saito's go-to-guy for help.
• Dishing Out Dirt: He's an earth mage.
• Ensign Newbie: During the war with Albion, immediately after he finishes basic training he finds himself assigned as a company commander to replace one who deserted. Thankfully one of the sergeants there is able to guide him.
• Handsome Lech: His good looks are why his initial flirting is often successful. Then Montmorency or one of his many previous paramours walk by, see him flirting, and tell him off. At which point, the current girl also tells him off.
• Jerk with a Heart of Gold: Once one gets past his overwhelming narcissism, Guiche is actually a nice guy. By season three, he and Saito are 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...
• Ladykiller in Love: Towards Montmorency. It's unfortunate that he has Commitment Issues because she's the only girl he's truly interested in.
• Large Ham: Regularly hamming it up with his rose and his familiar affection and his charming.
• Marionette Master: His signature style is conjuring statues to battle for him.
• Named After Somebody Famous: Antoine V de Gramont, Duke of Guiche, a French nobleman and Lieutenant General.
• Number Two: Ironically, Saito is the Vice Captain of Guiche's knight unit, the Ondine Knights, while Guiche is The Leader but no one cares and they seem to treat Saito as the leader more than Guiche. Guiche doesn't mind much.
• Princely Young Man: A nobleman Prince Charming type who uses this guise to flirt with younger girls.
• Religious and Mythological Theme Naming: Verdandi is the Norse Goddess of the Present.
• 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.
• Suck My Rose: He uses a rose instead of a wand as a magical focus, to complement his Casanova appearance.
• Tsurime Eyes: Inverted as he's not normally one for seriousness or strength of will of any kind.

Montmorency

Montmorency Margarita la Fere de Montmorency

Voiced by: Mikako Takahashi (JP), Samantha Carr (EN), Analiz Sánchez (Latin-American Spanish)

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 falls in love with Saito, instead becoming friends and teammates with him.

---

• Belligerent Sexual Tension: With Guiche. She may be a Tsundere Clingy Jealous Girl, and Guiche a consummate womanizer, but they do love each other.
• Beta Couple: With Guiche. Their relationship experiences similar ups and downs to Saito/Louise, but to a lesser extent.
• Clingy Jealous Girl: Not to such violent extents as Louise, but she doesn't like it whenever Guiche is in another of his exploits.
• Elemental Eye Colors: She's a water-type mage with blue eyes.
• In-Series Nickname: "Monmon", courtesy of Saito.
• Making a Splash: She's a water mage.
• Overly Long Name: Montmorency Margarita la Fere de Montmorency
• Proper Tights with a Skirt: The difference in modesty compared to Louise can be compared to the level of Tsundere.
• Regal Ringlets: Her hair is styled into old-fashioned ringlets because she's a noblewoman and has servants to do it for her. Two of the ringlets are in front of her ears, making it double as Ojou Ringlets.
• Repetitive Name: She has "Montmorency" as a given name and surname.
• Tsundere: Not as much as Louise, but she is this to Guiche. She states that she's dating him to "kill time", but gets jealous when he flirts with other girls. Then she gets teary-eyed when he goes off to do something dangerous.
• Tsurime Eyes: Many of her scenes involve her getting angry with Guiche, so she tends to sport these quite often.
• Youthful Freckles: For cuteness and (perhaps) the immaturity of youth, considering her relationship with Guiche.

Malicorne

Malicorne de Grandple

Voiced by: Hikaru Tokita (JP), Marin Miller (EN), Emilio Treviño (Latin-American Spanish)

A chubby student in Louise's class, is a wind mage with an owl familiar. Becomes much more important and useful in Seasons 3 & 4.

---

• Ambiguously Bi: He's clearly into girls, but has some otherwise questionable moments like when he seems to take an obscene amount of pride in having manboobs and even shoves Saito's face into his own manboobs.
• Ascended Extra: Doesn't get to do much until Season 3, when he becomes a member of the Knights of the Undine.
• Big Eater: Rare is the scene where he is not eating.
• Blow You Away: He's a wind mage.
• Blush Sticker: Pink blush marks are frequently an addition to his face.
• Crazy-Prepared: He always carries a lot of spoons on his person, so he can eat no matter the situation.

• Fat Idiot: Not dumb, but he acts pretty silly and his stomach is harder to miss.
• Super-Senses: He has a spell that lets him see things up to 15 miles away.
• Throw the Dog a Bone: He starts to get girls later in the series, then he's dumped in the third season due to the peeping incident. Then regains them in Season 4 for being the Queen's guards.

Tiffania

Tiffania Westwood

Voiced by: Mamiko Noto

A well-endowed half-elf who Saito remembered as "the big-breasted fairy who saved his life" once. She appears in the third season as a regular character, and also has feelings for Saito.

---

• All-Loving Heroine: She is as friendly with humans as with elves, despite the Fantastic Racism on both sides, and even the Alpha Bitch who bullied her is eventually won over.
• Boob-Based Gag:
  • Tiffania's enormous boobs are the source of many jokes, such as people wondering if they are real.
  • During the Sleipnir Ball (in the anime), she masquerades as Saito; Louise thought the one she saw was Saito, but looking down a bit, she saw a huge chest, because the magic did not remove Tiffania's chest size.
• Buxom Beauty Standard: Her breasts are often called to "debate" by many of the male characters in the series, and all like them.
• Even the Girls Want Her: By the power of both her huge tits and her genuinely kind and sweet personality, the other female students at the academy also like her along with the male students.
• Fantastic Racism: She has to hide her Unusual Ears to avoid the prejudices that elves face in human society.
• 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 the added ability to unleash it as destructive spells (on command of his master), or revive himself by using some of it.
• Graceful Loser: In the Grand Finale. She attends the Official Couple's wedding and looks genuinely happy for them.
• Hair of Gold, Heart of Gold: Her long golden hair is matched by golden personality; she's the nicest and friendliest mage at the academy.
• Half-Human Hybrid: Her father is human. She inherited her Void magic and buxom figure from her father's side of the family. Both traits are unheard of in elves.
• I Just Want to Be You: She turns into Saito because of a magic mirror that temporarily turns whoever looks into it into who they most want to be.
• Innocent Blue Eyes: Again, very sweet, very kind, and also ignorant of the world outside her village. Despite the badblood between humans and elves she has nothing against anyone.
• Innocent Fanservice Girl: As a contrast to the other well-endowed mage on campus, Kirche, who is far more likely to flaunt it. One example of this is when she asks Saito to check if her chest is real by touching them.
• 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.
• Mind Control: Her Mind Wipe spell erases memories of events and dispels any mind-control magic used on a target. This is her signature spell as a void mage.
• Ms. Fanservice: No surprise, she is the most buxom character of the series.
• Naïve Everygirl: Pure hearted girl whose insecure about her body and is picked on by an alpha bitch? Check, at first. After the inquisition she becomes popular and wiser, without losing her kind nature.
• Nice Girl: Friendly, compassionate, sweet-natured; the nicest girl at the Academy.
• No Social Skills: She grew up alone so she has no experience with socializing.
• Pointy Ears: She's a half-elf with the long and pointy ears characteristic of her race.
• Power of the Void: Like Louise, she is a void mage. Her signature here is erasing memories and mind control.
• Rescue Romance: She begins to develop feelings for Saito after he defends her during one of the student's inquisition in Season 3. It gradually turns into a Love Epiphany by Season 4.
• Tareme Eyes: Reflecting her gentle personality and contrasting with Louise, her main rival.
• Third-Option Love Interest: The "fight" for Saito's heart was narrowed to Siesta and Louise, until Tiffania made her debut. It intensified when she unintentionally contracted Saito as her familiar.

Julio

Julio Cesare

Voiced by: Daisuke Hirakawa

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.

---

• 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. This is due to his power as Vindalfr.
• Chick Magnet: Much like Saito, he's pretty popular with ladies.
• Demoted to Extra: Zigzagged. He's important in season 2 but in Season 3 he's largely a character in a crowd setting, and only gets a few lines at most. Then in season 4 he becomes much more important.
• Duality Motif: He has one red eye, the other blue — called the "Moon Eyes" after the twin moons of Halkeginia.
• Good Shepherd: A 'flamen' (holy man/cleric) on loan to Henrietta. It's downplayed in that he claims he has "returned to secular life" upon arrival at the academy.
• Irony: Saito is the harem male lead of the series but ironically, Julio happens to be able to attract girls in even greater numbers than him.
• Named After Somebody Famous: A downplayed version—he's named after a Romaglian dictator who shares the same name as a certain famous Roman emperor.
• New Transfer Student: He joins the cast when he's sent as a transfer student to Tristain Academy of Magic.
• Passing the Torch: In the Light Novels, he later becomes Josette's familiar as the new Mjöðvitnir after Vitorrio's death.
• Princely Young Man: A Prince Charming Type. Most of the female population at the academy swoons over him because of his chivalric attitude.
• The Trickster: Exploiting harem hijinks for one. It's unusual since he's a loyal familiar for the Pope.
• Tsurime Eyes: Unlike Saito, he has these most of the time instead of just in dangerous situations.
• Vitriolic Best Buds: With Saito, eventually. They don't always get along, but Julio helps Saito in his relationship with Louise. He even ends up being Saito's best man in his wedding.
• Warrior Monk: A priest with a sword in hand.

Familiars

Flame

Flame

Kirche's familiar.

---

• Familiar: Flame is the familiar that Kirche summoned and made a contract with.
• Fiery Salamander: Flame is a fire-breathing salamander the size of a large dog.

Sylphid

Sylphid/Illococoo

Voiced by: Satomi Arai (as a dragon), Yuka Iguchi (as a human)

^{Click here to see her human form}

A female wind dragon and Tabitha's familiar.

---

• Big Eater: She seems to be a bottomless pit as far as food goes.
• Big Little Sister: Played With. They aren't actually sisters, but she refers to Tabitha as "Onee-sama". However, her human form looks old enough to be Tabitha's older sister or mother.
• Curtains Match the Window: Her human form has blue hair and eyes.
• Energetic and Soft-Spoken Duo: Unlike her quiet and stoic master, Sylphid is very energetic and outgoing.
• Familiar: She's the familiar that Tabitha summoned and made a contract with.
• Hot in Human Form: She's a dragon who can take the form of a voluptuous woman.
• Innocent Fanservice Girl: Because she's a dragon, she doesn't grasp the nudity taboo and has no problems with being naked in front of Saito and others.
• Sexy Slit Dress: Her human form wears a dress with a slit on both sides to show off her legs.
• Shipper on Deck: She ships SaitoxTabitha.
• Weredragon: She's a dragon who can turn into a human at will.
• Womanchild: Her human form looks like a young woman, but she behaves like a little kid.

Staff

Siesta

Siesta

Voiced by: Yui Horie (JP), Xanthe Huynh (EN), Melissa Gedeón (Latin-American Spanish)

A maid at the academy. She has a crush on Saito, and unlike Louise she treats him very kindly. She seems to not mind Saito getting punished because she ends up taking care of him anyways.

---

• Adaptational Jerkass: The anime has Siesta appearing in events she was no part of originally, which often results in her scheming and getting in Louise and Saito's way. Because of this, the anime makes Siesta come off as very clingy and ready to get in the way of Louise and Saito's relationship at every given opportunity.
• Ascended Extra: In the anime, Siesta appears in many situations and events that originally, in the novels, she was no part of.
• Be a Whore to Get Your Man: She is originally a modest and gentle maid, but falling in love with Saito makes her push herself too much. Considering Louise's flat chest, her own sex appeal is one of her better "weapons".
• Betty and Veronica: The Betty to Louise's Veronica because she is a Japanese commoner instead of a European-ish noblewoman. The roles are arguably switched in the anime where she is more conniving.
• Big-Breast Pride: After the first season, she becomes very boastful about her breast size (thanks to picking up on Saito's preference for large breasts). She frequently brags about her large breasts to Louise, knowing full well that her direct love rival has a major case of A-Cup Angst.
• Bitch in Sheep's Clothing: She seems like a cute and sweet Meido, coming across as the "nice one" of Saito's admirers especially when compared to his Tsundere master/girlfriend. However, as the anime series goes on, Siesta shows herself to be vicious, clingy and manipulative as she schemes to take Saito from Louise and actively tries to create situations that will get him hurt.
• But Not Too Foreign: She is the descendant of a World War II Japanese pilot who strayed into Tristain.
• Clingy Jealous Girl: Once Tiffania shows up, Siesta shares Louise's utter contempt for the poor half-elf girl because both see her as yet another love rival aiming for Saito.
• Graceful Loser: In the Grand Finale. We're not entirely sure, but she attends the Official Couple's wedding and looks genuinely happy for them, but it isn't entirely clear if she will still work for them.
• Meaningful Name: A relatively minor example in that one of the databooks mentions that her "hobby" is napping. The word siesta is Spanish for "short nap taken in the afternoon".
• Meido: A servant in the academy that sports the classic maid look. In Season 3, she is appointed by Henrietta to be Saito's personal maid.
• Ms. Fanservice: From Season 2, she invokes her sex appeal, mainly by showing off her big breasts, to try and win out over Louise.
• Naked Apron: Invoked Trope on one occasion (see Be a Whore to Get Your Man) and to great effect.
• Nice Girl: Initially, she was a kind girl who treated Saito with more respect and care than Louise did. As the fight over him escalated, she gradually began to turn less cordial.
• Only One Name: She doesn't have a surname due to being a commoner.
• Rivals Team Up: She considers Louise her rival, but is willing to put her grudge with Louise aside and work with her to prevent other female rivals from getting to Saito.
• Romantic Runner-Up: After several seasons of competition, she watches Saito marry Louise.
• Single Woman Seeks Good Man: She fell in love with Saito because he stood up for the rights of the people who can't use magic.
• Tareme Eyes: To highlight her gentler and more humble personality (before Flanderization set in) she has rounded eyes.
• The Tease: Her favorite seduction technique is to let, and in some cases, force Saito to touch her breasts.
• Through His Stomach: She resorts to the food tactic at times in her many attempts to win Saito's heart.
• Took a Level in Jerkass: As the anime progresses, Siesta shows signs of enjoying Louise's constant abuse of Saito. She starts to often join Louise in beating Saito if he does something to anger her, and on more than one occasion, attempts to seduce him knowing full well that Louise will beat the living hell out of him for it. In Seasons 3 and 4, she's openly enjoying Saito getting beaten just so she'd be the one to take care of him.

Ms. Longueville

Miss Longueville/Matilda de Sachsen-Gotha

Voiced by: Akiko Kimura (JP), Michelle Ann Dunphy (EN), Liliana Barba (Latin-American Spanish)

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.

---

• Beleaguered Assistant: When she is Osmand's secretary, due to his status as a Dirty Old Man.
• Dishing Out Dirt: Her nickname is Foquet the Crumbling Dirt/Earth.

• Freudian Excuse: Hates nobles because her father was betrayed and killed by Albion nobles.
• The Glasses Come Off: When she reveals herself as Foquet.

• Reluctant Fanservice Girl: A little in the anime, considering that Osmand and the Duke can't keep their eyes off of her.
• Sexy Secretary: Osmond thinks so but then again he's not picky.

Mr. Colbert

Jean Colbert

Voiced by: Takuma Suzuki (JP), Kaiji Tang (EN), Esteban Desco (Latin-American Spanish)

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 advanced than Halkegenia's.

---

• Absent-Minded Professor: He's so focused on "Dragon's Blood" or some other topic that he sometimes neglects tasks or wanders off.
• The Atoner: Deeply regrets the burning of Agnes' home village, and due to this has developed a desire to help the nation with his fire magic.
• Bald Mystic: Although he looks like an unassuming teacher at first, his baldness is a subtle signifer of his past as a once famous fire mage and former soldier.
• Cool Teacher: Downplayed. The students aren't his fans but they also don't think his lessons are boring.
• Dark and Troubled Past: The burning of Agnes' home village and the various innocent lives he ended long ago due to misinformation spread by corrupt nobles, while also burying his "Flame Snake" title due to how much bottomless regret it brings to him.
• The Engineer: Builds an engine in the manga and other inventions throughout the series.
• Faking the Dead: He pretends to die after his duel with another fire mage at the academy.
• For Science!: He's not being paid for his research or inventions; it's what he does in his spare time.
• Gadgeteer Genius: He reverse-engineers a fighter plane to invent the local version of gas-powered aircraft and is capable of artificially creating its fuel.
• I Was Quite a Looker: He was better looking as a young man.
• Playing with Fire: Fire mage.
• Shell-Shocked Veteran: His reason for hating war is going through one as an officer and burning a completely innocent village down when it was reported that it was contaminated by a vicious disease, which was an outright lie made by corrupt nobles, in which he immensely regrets shortly after saving poor young Agnes.

Kaita

Kaita The Gust

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.

• Blow You Away: He's a wind mage.

Osmand

Osmand

Voiced by: Takeshi Aono (JP), Jonathan Meza (EN), Pedro D'Aguillón Jr. (Latin-American Spanish)

An ancient Square-class wizard and Headmaster of the Academy. Has a mouse familiar. He is perverted and often uses his familiar's size for lecherous purposes, but he is said to be a powerful mage.

---

• Dirty Old Man: Why else would he uses his familiar's size for lecherous purposes? He's dirtier in the OVA.
• Informed Ability: The old man is said to be a square mage, but never fights. We don't even know what his specialty is.
• Wizard Classic: A tall and old man in a long robe with a longer beard of pure white.

Kingdom of Tristain

Henrietta

Henrietta de Tristain

Voiced by: Ayako Kawasumi (JP), Cassandra Lee Morris (EN), Andrea Arruti (Latin-American Spanish)

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.
• Anguished Declaration of Love: She makes a heartfelt cry to Prince Wales... or better said, the copy of his body, animated with a little of his soul.
• Battle Ballgown: Her battle armor is a ballgown with the only pieces of real armor worn on the arms, legs and shoulders.
• Big-Breast Pride: Downplayed. Unlike most of Louise's rivals, she doesn't like to brag about their size difference, but she's shown to be Not So Above It All while having a Catfight over Saito while bathing, she can't help but act smug when she notices Louise staring at her chest in jealous awe and later calls her a "Carpenter's dream".
• Break the Cutie: Poor Henrietta and Wales... the tragic romance is not the only hardship she encounters.
• Buxom Beauty Standard: One episode has her take a bath with Louise, and when Louise sees her rising out of the water she can't help but feel jealous of how much bigger Henrietta is, describing her as being "unnecessarily sexy".
• The Chains of Commanding: It's not easy being queen; corrupt nobles, war plans, international politics, etc. Several times these chains prevent her from helping her friends (such as Louise) because doing so would have backlash on the country as a whole.
• Childhood Friends: Louise was her playmate when they were both growing up. Because of this, she sees Louise more as an equal she can confide in and rely on instead of one more noble subject.
• Graceful Loser: In the Grand Finale. We're not entirely sure, but she is the witness to the Official Couple's wedding alongside Tabitha/Charlotte and looks genuinely happy for them.
• The High Queen: She ultimately ascends to Queen with the power and popularity to go with it.
• I Just Want to Be Normal: She's shown to resent the responsibilities of her life as a ruler and often wishes she could just be a normal girl.
• I Just Want to Be You: She turns into Louise because of a magic mirror that temporarily turns whoever looks into it into who they most want to be.
• Jerkass Ball: Season 4, Episode 6 shows a meaner side of her, telling Louise that she's in love with Saito and then taunting her and her poor, flat chest. Then they get into a tussle, just like they used to when they were children. By the end of the scene she's back to normal.
• Kissing Cousins: She's in a secret relationship with Prince Wales of Albion, who happens to be her cousin. It ends in tears...
• Lord Country: She rules over the Kingdom of Tristain and her family name is de Tristain.
• Making a Splash: She is a water mage.
• Ms. Fanservice: In Season 2, where she has a scene in a Sexy Soaked Shirt, and Season 4, where she appears in a sexy negligee.
• Named After Somebody Famous: Henrietta Anne, youngest daughter of King Charles I of England and sister of King Charles II.
• Not So Above It All: Despite being in love with Saito, she remained a serious character for the longest time and didn't get into any bickering with any other girl over Saito. In the fourth season, she finally gets into a fight with Louise over Saito's affections for the first and only time.
• Politically-Active Princess: She's very active politically. At one point she hires Saito and Louise 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 and it escalates in Season 4, where she isn't afraid of telling to Louise's face that she loves him.
• Star-Crossed Lovers: With Prince Wales, her first cousin. Politics prevent them from being together officially, so they have covert meetings.
• Tareme Eyes: Fitting her role as a benevolent monarch, she has rounded eyes.
• Third-Option Love Interest: While Saito gets a lot of Ship Tease with most of the main female cast, Henrietta gets the most focus behind Louise and Siesta.
• Tough Leader Façade: The position of Queen demands a confident, competent, and most of all spotless image, and so Henrietta has to maintain this image for the public. She takes solace in her friendship with Louise, when no one can see her.

Agnes

Agnes Chevalier de Milan

Voiced by: Michiko Neya

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.
• Boyish Short Hair: Sidetail variant, to better contrast the fashion of noblewomen.
• 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. Her biggest scene is 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. All of her scenes last around 5 to 30 seconds and she doesn't 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.
• Fake-Out Make-Out: With Louise during a spying mission.
• 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.
• Out of the Inferno: Done awesomely, but not in the usual way; as Lishman is savoring his victory, Agnes leaps out of the flames and skewers him.
• Muggle Power: Believes herself to be superior to mages in combat because she can fire her gun faster than they can cast a spell. When she encounters the lieutenant fire mage that burned her village, she is overwhelmed.
• Sergeant Rock: When training the academy mages she is tough and strict and does not tolerate back talk or any other kind of resistance.
• Sword and Gun: She prefers a pair of pistols and a longsword.
• Token Wholesome: She's the complete contrast of most of the fanservice-laden girls in the series, despite having a decently-sized bust, a different variation of Zettai Ryouiki, and her Fake-Out Make-Out moment with Louise. It is a perfect contrast to her Girly Girl partner, Princess Henrietta, who is, like several other major female characters in the series, a Ms. Fanservice.
• Tsurime Eyes: There is no softness in her; her personality is as sharp as her eyes.
• Undying Loyalty: To Henrietta. It's thanks to her granting her a military position that she is not a homeless and starving vagrant.

Wardes

Viscount Jean-Jacques Francis de Wardes

Voiced by: Tomoyuki Shimura (JP, adult), Tatsuhisa Suzuki (JP, young), Charles Rengel (EN, adult)^note Kaiji Tang in Episode 7, Brian Breth (EN, young), Mario Castañeda (Latin-American Spanish)

Wardes is the captain of Tristain's Griffin Knights and Louise's fiancé. His runic name is 'Lightning'. When Louise is sent on a mission for Princess Henrietta, Henrietta sends him with Louise to help and guard her. He is polite and a gentleman but tends to get carried away whenever she wants something done.

---

• Beard of Evil: When he arrives, Ward is shown a few times in flashbacks where he acts kind to the main character, and has no beard. However, in the present, he has a beard, and is, well, evil.
• Blow You Away: His sword also functions as a wand, from which he uses wind magic.
• Broken Pedestal: To Louise who believed him to be The Paragon. It was heartbreaking for her to realize he was treacherous.
• Death by Adaptation: He dies in the anime.
• Disposable Fiancé: In the first season, he's engaged to Louise. This is to up the tension between her and Saito.
• Doppelgänger Attack: He has a spell that allows him to create up to four wind clones of himself. The clones have full autonomy which allows them to coordinate with each other.
• The Mole: Secretly a member of Reconquista.
• Scars Are Forever: He ain't getting that arm back. It's his shoulder that gets wounded in the anime and his arm is bandaged so it wouldn't look too violent.
• Self-Duplication: He can create copies of himself with wind.
• Shock and Awe: He uses his wand/sword for electric spells.
• Wicked Cultured: Dresses quite nicely and he is a noble and a mole.

House la Vallière

Centurion

Duke Centurion la Vallière

Voiced by: Jiro Saito (JP)

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.

---

• Action Dad: As a mage with far more experience than any student at the academy, he is powerful. Not living up to his legacy is part of Louise's angst.
• Boyfriend-Blocking Dad: He 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. However, by the time they get married, he seems to have accepted their relationship and looks genuinely happy for them.
• Give Away the Bride: The Grand Finale shows him bringing his youngest daughter to meet Saito at the altar.
• High-Class Glass: His monocle is befitting his noble status.
• Magic Staff: He uses one of these instead of a wand.
• Off with His Head!: Wanted to behead Saito after the incident with Louise and the boat.
• Papa Wolf: He genuinely cares for Louise and is willing to oppose the state if it tries to exploit her talents like a tool.
• The Patriarch: The head of House la Vallière.

Karin

Duchess Karin Desiree la Vallière

Voiced by: Yoshiko Takemura (JP)

The mother of Louise, Eleanor and Cattleya. She was the strongest Wind magic-user ever to serve in the Tristain military according to records.

---

• Action Mom: As a mage with far more experience than any student at the academy, she is powerful. Not living up to her legacy is part of Louise's angst.
• The Archmage: She's believed to be the strongest human mage in the setting.
• Blow You Away: A square-class wind mage.
• Classy Cravat: She's a Duchess wearing a cravat.
• Cool Mask: She wore an iron mask during her time as Heavy Wind.
• Curtains Match the Window: Her hair and eyes are both pink.
• The Dreaded: Louise was much more frightened of her mother than the Queen's punishment.
• Hero of Another Story: She had her own adventures when she was Louise's age. Her past is elaborated in two spin-off novels.
• Lady of War: She's an elegant noblewoman who also happened to be a very powerful knight in the past.
• Prim and Proper Bun: Part of her hair is tucked away and pinned behind her head. Oddly enough, she has two free tails down the front.
• Psycho Pink: She's a cold and dreaded woman with pink hair.
• Red Baron: She is also known by her nickname "Heavy Wind".
• Retired Badass: She's the former Commander of the Manticore Corps. Currently, she has retired and lives as a regular noblewoman with her family.
• Strong Family Resemblance: While not apparent in the series proper, she looked almost exactly like her daughter Louise when she was younger.
• Sweet Polly Oliver: During her time as Commander, she hid her gender. Considering she favored hot pants and thigh high boots when she was younger, it's unknown how she pulled this off.
• Tsundere: Not apparent in the present day, but she had a bit of a propensity to blow up at her future husband when he angered her, not unlike her youngest daughter does with hers.
• Tsurime Eyes: Her sharp and stern-looking eyes match her harsh demeanor. She passed it on to her eldest daughter. In the past, her eyes were more like Louise's.

Cattleya

Cattleya de la Fontaine

Voiced by: Kotomi Yamakawa (JP)

Cattleya 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 helps Louise escape from her house to go back to the Academy. She knows Louise well, and can easily tell that Louise is in love with Saito, even when Louise denies it. Although Cattleya is older than Louise, she isn't married due to the fact she is ill. Cattleya is an Earth mage.

---

• Buxom Beauty Standard: She has the biggest breasts out of the women in her family, much to her flat-chested sisters' envy. Her ample chest is one of the reasons why Louise's ideal self is modeled after Cattleya.
• Curtains Match the Window: Both her hair and eyes are pink.
• Dishing Out Dirt: She's an Earth mage.
• Friend to All Living Things: She has a lot of pets. The light novels and the anime imply that her bedroom looks like a zoo.
• Heal It with Water: While she's primarily an earth mage, she does show some affinity for healing spells using water.
• Incurable Cough of Death: She has some disease that makes her cough, that is about it.
• 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.
• Nice Girl: Her kindheart, patience and tolerance is highlighted next to her short-tempered sister and her cold-hearted mother.
• Odd Name Out: Despite being born of Duke and Duchess de la Vaillere, she was given the surname of Fontaine due to her Incurable Cough of Death.
• Onee-sama: Her younger sister Louise idolizes her.
• Overly Long Name: Cattleya Yvette La Baume Le Blanc de La Fontaine.
• Rose-Haired Sweetie: She has pink hair, like her mother and younger sister. Unlike them, Cattleya is very kind and sweet.
• Shipper on Deck: She's the only one in the family who supports Louise's relationship with Saito.
• Sibling Yin-Yang: With Eleanore. Cattleya is the soft and sweet sister in contrast to the the angry and harsh Eleanore.
• Strong Family Resemblance: She looks nearly identical to her mother and her youngest sister, but with bigger boobs.

Eleanore

Eleanore la Vallière

Voiced by: Kikuko Inoue (JP)

Eleanore 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.

---

• A-Cup Angst: Similar to Louise, she dislikes being flatter than Cattleya.
• Berserk Button: Being reminded about her failed engagement makes her even harsher than normal.
• Big Sister Bully: She bullies her youngest sister Louise; ordering her around, pinching her cheek until she's addressed as "Onee-sama", dragging her out of the academy, etc.
• Hair-Trigger Temper: Similarly to her youngest sister, it's easy to set her off.
• 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.
• Onee-sama: Louise calls her this out of fear/protocol instead of adoration like Cattleya.
• Overly Long Name: Eleanore Albertine Le Blanc De La Blois De La Vallière.
• Scary Shiny Glasses: When she gets mad, her glasses do this.
• Shared Family Quirks: She and her youngest sister Louise have the same short fuse and insecurity about being flat-chested.
• Sibling Yin-Yang: With Cattleya. Eleanore is the angry and harsh sister in contrast to the soft and sweet Cattleya.
• Tsundere: Even worse than Louise and a deconstruction. Internally she gushes about the Earl of Burgundy but he never saw her feelings for him. He genuinely thought she hated him and called off their engagement to avoid marrying a woman who he thought despised him.
• Tsurime Eyes: Like her mother, she has the pointed eye shape and inherited her harsh personality as well.
• Whip of Dominance: She's a strict and bossy woman and just her younger sister, she carries a whip for "disciplinary" reasons. She ends up whipping Saito when he does things like (accidentally) going into her room or staring at her chest.

Gallia

Joseph

King Joseph de Gallia

Voiced by: Jurota Kosugi (JP)

The main antagonist of the Familiar of Zero series. 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.

---

• Abusive Dad: He treats his daughter, Isabella, like dirt, always sending her away in disgust, purely because she reminds him too much of himself.
• Big Bad: Joseph is responsible for the murder of his younger brother Charles and usurping his throne and attempting to poison his niece to insanity, which was halted because of her mother's intervention. Joseph is responsible for kickstarting Tabitha's escape to Tristain, attempting to use her as an agent and even force her to betray her True Companions and sentence her to death if she failed. To a much wider extent, Joseph is responsible for the the rise of Reconquista in the shadows by helping them and its true leader and his familiar Sheffield to incite wars against Tristain for his plans of locating the other Void mages, thereby making him the series' true mastermind. After his death, the Ancient Dragon later takes his position.
• Blood Knight: His quest is to feel emotion due to the Void within his heart, but his methods are ruthless and bloody, even starting countless wars to other neighbouring countries just to achieve his twisted goal to the end.
• Blue Is Heroic: A complete inversion. His bright blue eyes and light blue hair often complements with his detached and cruel personality. And being the Big Bad of the series.
• Cain and Abel: Evil older brother, check. Murdered younger brother, check again.
• The Caligula: As the king of Gaul, he ticks off most of the checklist. The only reason he doesn't fully fit the trope is that he is completely incapable of anger, but he goes out of his way to trigger wars, purely so he can laugh as the world burns around him.
• The Chessmaster: Has a literal magical chessboard to complement his Evil Plan.
• Disc-One Final Boss: Despite being the utmost threat to the heroes across the entire franchise, his death in Season 4, Episode 3 only ends his own villain arc, as the heroes have to face the final Big Bad, the Ancient Dragon, who would later take his position near the end of the series.
• Evil Overlord: After forcibly murdering his brother, Joseph becomes the de facto King of Gallia. He is a cruel ruler where he is willing to secretly further the Reconquista to stoke wars with Tristain and its allies including Romalia and Germania just to use it for his twisted motivations to feel any remorse.
• Evil Uncle: While he isn't the main character's uncle he is an uncle to Tabitha. He is pretty evil too.
• Flash Step: Acceleration/Haste enables him to keep up with the Gandalfr's speed.
• Green-Eyed Monster: The reason he hated his little brother is jealousy.
• Inverse Law of Sharpness and Accuracy: His Explosion spell is less powerful than Louise's but is more accurate so he can aim it at a designated target, unlike hers which is more of an Area of Effect spell.
• 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 himself feel regret for killing his younger brother, but in a twisted way.
• Obfuscating Stupidity: Keeps up a public persona of a weak and useless man.
• Omnicidal Maniac: He wants to kill everybody. Purely for the sake of trying to feel something, anything, even if it's merely the sadistic pleasure of watching others wallow in the despair he caused.
• Power Copying: He can absorb the abilities of other Void Mages through his familiar, "the Mind of God".
• Power of the Void: One of the four void mages.
• The Sociopath: The man is incapable of feeling anything, so he always relishes the suffering of others, especially at his own hands. In fact, the quickest way you can find yourself at the point of his dagger is to say you love him. If he spends any effort on anything, it's purely so he can come back and destroy it later, and enjoy watching it burn. F's third episode's climax somewhat subverts this trope, as shown that he expressed signs of genuine affection to Sheffield before he died at the exploding ship with her. However the end result is ambiguous.
• Stuff Blowing Up: Explosion, though his Void specialty is actually Acceleration/ Haste and not Explosion.
• Super-Speed: His specialty is 'Acceleration'; speeding up his movements.
• Villain Has a Point: He's right to give his elf "ally," Bidashal, a good Breaking Speech. The pompous, self-righteous, arrogant twit has done a great many nasty things in the service of Joseph Gaul, never hesitating or questioning Joseph's goals and intentions, until after his appointed task is done and only then expressing outrage, calling Joseph a "demon," while completely neglecting everything he's done not only to enable Joseph's evil deeds, but all the blood on his own hands.
• Walking Spoiler: Many of the conflicts in the series are directly tied back to him including the murder of his brother, thus making it impossible to talk about him without spoiling everything.

Charles

Duke Charles de Orléans

Joseph's younger brother and the father of Tabitha/Charlotte.

---

• Benevolent Mage Ruler: Charles was the more benevolent ruler of Gallia in his short-lived term as the King. He is a stark contrast to his older brother Joseph who largely served as an Evil Overlord after he murdered him with a poison arrow and subsequently usurped his position. He is also a more competent mage than his older brother Joseph, which also increased his brother's seething envy and hatred towards him, ultimately leading to his demise.
• Small Role, Big Impact: While a largely flashback character, Charles' death became the centerpiece of Tabitha's exile to Tristain, her emotionless personality in the present and Joseph's rise to being an Omnicidal Maniac.
• Walking Spoiler: Any mention of Charles is impossible without spoiling the majority of the series' plot.

Duchess de Orléans

Duchess de Orléans

Voiced by: Mika Doi (JP), Allison Moffett (EN)

The young Duchess before her insanity.
^{Click to show the Duchess after being driven insane.}

Tabitha/Charlotte's mother and the Duchess of Orléans.

---

• Driven to Madness: After taking the potion that was meant for Tabitha/Charlotte, which was perpetrated by Joseph, she became insane and maddened who sees Charlotte's doll Tabitha as her "daughter". No longer in effect after she was cured.
• Expository Hairstyle Change: In her last appearance in F, she is seen wearing her hair in a bun after she was cured.
• Parental Abandonment: Only during her time when she was insane. She perceives the doll, Tabitha, as her daughter and her actual daughter as nothing more than a "traitor" to her family.
• Surrogate Soliloquy: During her induced madness caused by Joseph she is seen talking to Tabitha, Charlotte's doll, and mistakes her as the doll as her real daughter. When the actual Tabitha/Charlotte shows up, however, she quickly loses it and calls her a "traitor" trying to "split" her family apart.
• Taking the Bullet: A non-lethal variant, where she saves Charlotte from the potion Joseph created for her by drinking it. At the direct expense of her being driven to insanity in Tabitha/Charlotte's stead.
• Unnamed Parent: Her first name isn't mentioned. She's either known as "Duchess de Orléans" or "Tabitha/Charlotte's mother".

Isabella

Isabella de Gallia

A light novel-exclusive character. She is the princess of Gallia and the only daughter of the late Joseph and his unnamed wife.

---

• Adapted Out: Isabella only exists in the Light Novels, being excluded from the anime adaptation.
• Clashing Cousins: Isabella initially acted antagonistic and cold towards Tabitha, her younger cousin, due to her father's death at the hands of her, Louise and Saito. But she subverts this trope when she saw Tabitha's mother for the first time, seeing the error of her ways.
• Daddy's Little Villain: She is the daughter of Joseph and has a very nasty personality.
• Heel Realization: She goes into this when she meets Tabitha's mother for the first time, realising that she, Tabitha and Josette are the only family left, causing her to have a change of heart. This led her to bury the hatchet with Tabitha and subsequently become a nun to make it up for the lengthy atrocities her father committed over the course of many years.
• Royal Brat: Being raised by Joseph, Isabella did not hesitate to scorn the newly-crowned Queen Tabitha/Charlotte, blaming her for the death of her equally abusive father.
• Sins of Our Fathers: After realising the errors of her father's ways and her own ways, Isabella takes up the job of a nun.
• Taking the Veil: She becomes a nun, in order to compensate for her father's sins and crimes he committed in his terror.
• True Blue Femininity: A subversion. She's a princess with blue eyes and light blue hair, as well as blue-coloured clothing. However, she's too much of a Royal Brat to be a proper example.
• Tsurime Eyes: Her sharp eyes fit with her cold and rude personality.

Josette (Unmarked Spoilers)

Josette d'Orléans de Gallia

The long-lost identical twin sister of Tabitha, who is revealed to be working at the church in Romalia. Like Tabitha, she later becomes Gallia's queen alongside her twin sister.

---

• Adapted Out: Similarly to Isabella, Josette only appears in the Light Novels and doesn't appear in the anime series.
• Always Identical Twins: She virtually has the same appearance as her twin sister Tabitha. It is the reason why she was once used by Vittorio and Julio to take the throne of Gallia from Tabitha in the past.
• Identical Twin ID Tag: She is very similar to her older twin Tabitha, in terms of appearance and personality. The only difference is her occupation as a nun and her outfit.
• Passing the Torch: After Joseph's death, she later becomes the new Void mage and Julio's new master, who is now the new Mjöðvitnir.
• Separated at Birth: She was separated from her twin sister during her childhood when she was taken by the Papacy of Romalia under Vittorio and Julio's orders to impersonate her twin and usurp the Gallian throne from her.
• Walking Spoiler: Mentioning about Josette will spoil the reveal that she's the missing twin sister of Tabitha.

Sheffield

Sheffield

Voiced by: Masako Katsuki (JP)

Joseph's familiar and later his right-hand, who once served as Cromwell's secretary. She is the true leader of the Reconquista and she serves Joseph on her side until their death. She comes from Rub' al Khali, being the only character who knows that she originates from there.

---

• The Dragon: She served as Cromwell's secretary, before she betrays him by killing him inside his prison cell. After she reveals to be Joseph's familiar, she is his loyal right-hand.
• The Heavy: Sheffield is the most prominent antagonist in the series due to her screentime, as well as the most prominent threat that Louise and Saito faces. However, she often answers to the franchise's Big Bad, her master Joseph.
• Magic Knight: Her powers as Joseph's familiar gives her the ability to use any magical artifacts, allowing her to learn anything and everything about magic theory.
• The Man Behind the Man: While Cromwell is purportedly the leader of Reconquista, she is later revealed to be its true leader and does so by killing him.
• Manipulative Bitch: She murders Cromwell and uses the Ring of Andavari to continue the war between Albion and Tristain. She then uses a poison to South Gotha's water supply to brainwash its residents, so she would use it as an opportunity to ignite an insurrection against Henrietta and Tristain.
• Red Baron: Mjöðvitnir, lit. "The Brain of God".
• The Starscream: She sees Cromwell as no longer useful, after his failed attack in Tristain that led to his imprisonment, before deciding to take the Ring of Andavari and reveal herself as Reconquista's true leader.
• Undying Loyalty: She serves as the most loyal confidante to Joseph, due to her status as his familiar, and more so upon her and his death at his ship during the climatic battle with Louise, Tiffania and Saito. Her last and final words is basically to leave herself and Joseph to die for good, where the trio complied before they are both Killed Off for Real.

The Elemental Siblings

The Elemental Siblings

---

• Arc Villain: He served as the main villain of the first season.
• Big Bad Wannabe: While he is seen as the main antagonist of the first season, responsible for starting the invasion of Tristain with his Reconquista army, he is nothing more than an Unwitting Pawn to Joseph's grand scheme of plans. Matters did not help when Sheffield soon betrays him during his imprisonment, where she steals the Ring of Andavari and becomes the organization's true leader.
• Unwitting Pawn: Despite being Reconquista's purported leader and causing the attack of Tristain, Joseph is the one who is initiating his plans in the shadows.

The Ancient Dragon (Unmarked Spoilers)

The Ancient Dragon

An ancient, powerful dragon that originally terrorized the Romalian city of Aquileia, before setting its new goal to target Tristain, specifically Louise and Tiffania due to their Void status.

---

• Achilles' Heel: While the dragon is largely immune to all magical attacks, powerful modern weapons including the F-2A Jet Fighter's missiles is enough to cause significant damage in its thick hide, revealing its molten body.
• Arch-Nemesis: It serves as the nemesis of the Void Mages. They serve as its major weakness when it was killed by Louise through her imbued Explosion spell when Saito gave all of his Lífþrasir powers to her. Conversely, they also serve as its major source of strength, as in the case when it fully evolves into a winged nightmare after devouring Vittorio, a Void mage. Henceforth the primary reason why it goes after Void users.
• Attack Its Weak Point: If sufficient damage is done to its hide, the molten body is its weakness and a lot of magical power is needed to kill it. As in the case when Louise fires her Lífþrasir-powered explosion onto the exposed body, permanently defeating it for good.
• Big Bad: Serving as one in F's Episodes 10 to 12 and the main antagonist after Joseph's death.
• Dark Is Evil: It's a giant black dragon with the only purpose is being a force of evil and destruction.
• Dragons Are Demonic: All the Dragon wants is to destroy anything and cause as much damage as it can regardless of lives, albeit its more specific targets are Void users including Louise and Tiffania, but anything else it causes damage is within collateral level at its worst. It is previously one of the reasons why Aquileia was targetted by the Dragon due to Vittorio, another Void user who was soon devoured by it.
• The Dreaded: The Ancient Dragon is feared by everyone who are unfortunate to encounter it. It is capable of even overpowering and devouring Vittorio, one of Romalia's most powerful mages, as well as destroying Derflinger without any hitch. Void mages including Louise and Tiffania also fear the mythical being and are definitely not safe from its wrath, as both of them turned out to be the dragon's main targets who target Void magic users.
• Final Boss: Traditionally the final main antagonist of the entire franchise the main characters faced and is considerably a more powerful threat to boot than any other villain in the series as a whole.
• Mighty Glacier: The Ancient Dragon is considered strong and powerful to everyone, but is considered slow. Doesn't mean it can't pack a dangerous punch.
• Mind Control: Its ability, Miasma, allows it to control other dragons, but it cannot control dragons like Sylphid or Julio's dragon. However, the third eye it has can bypass those measures, allowing it to control Julio's dragon with ease and lure towards it.
• Names to Run Away from Really Fast: The Ancient Dragon, just by its name, is a force too powerful to be reckoned with. Any magician coming in close contact with it are in for a certain doom, as in the case when it brainwashed Julio's dragon and attempted to kill Julio by luring it, but only Vittorio's Heroic Sacrifice saved him from its proverbial jaws of death.
• Omnicidal Maniac: It is responsible for destroying the city of Aquileia and the countless deaths of the city's people and even obliterating the fleet stationed in Magic Academy before initiating its rampage for one last time.
• One-Winged Angel: After its supposed "defeat", the Dragon then harkens its awakening as it evolves into a new form with wings, giving newfound abilities including flight, which happened after devouring Vittorio from the previous episode.
• Third Eye: Used to brainwash any dragons, regardless of the dragon's immunity to it, as in such the case when it was able to brainwash Vittorio's dragon when it was initially resistant to it.
