    Lisesharte Atismata 

Lisesharte Atismata

Drag-Rides: Tiamat and Chimeric Wyvern

Voiced by: Lynn

The first princess of the Kingdom of Atismata.

  • Adaptational Wimp: Despite having a modest reputation as a fighter and a technician in the anime; Lisesharte rarely, if ever, wins a fight by herself. Most of the time, she gets into trouble and Lux has to bail her out. In the light novels, she kills Hayes; but in the anime, Lux delivers the final blow.
  • Affectionate Nickname: She allows those close to her to call her Lisha.
  • Attack Drone: Tiamat's special armament <Legion> are long-range throwing weapons of small streamlined metals which are controlled and hold a propulsive strength themselves. Usually, four of them were equipped to the airframe; after launch, the units could freely move and directly impact damage to the enemy. A maximum of 16 can be deployed.
  • Ascended Fangirl: Implied to be one to the "Black Hero" by episode 1's opening.
  • Awesome Moment of Crowning: She officially becomes Queen of Astimata in episode 12, to the cheers of the entire population.
  • Battle Couple: With Lux. He can, and does, trust his back to her at all times, without exception, even after they just met and he was dueling her. As a prime example, when going up against Hayes, he sends Philuffy and Krulcifer away to deal with the insurrectionists while tag-teaming with Lisha to take down Hayes and the giant. Celestia wasn't even present.
  • BFG: Tiamat's auxiliary armament <Seven Heads>, it is a main armament two times bigger than the Breath Gun, connected to Tiamat’s right shoulder and right arm. A huge gun barrel with seven muzzles.
  • Break the Cutie: During the time she was kidnapped, she dearly wished to be saved by her father, and all she could think about was her family, so she didn't take well that her father abandoned her and the fact that sometime later he even died along with her little sister, leaving her alone.
  • Broken Bird: She has suffered abuse, abandonment, being orphaned, and loneliness. Her tragic past is such a trauma for her that she had a choked voice and was moved to tears just by telling her past to Lux.
  • Category Traitor: Everyone from the old Empire, bar Lux, and Airi, calls her a dirty traitor, including herself, because the coup set her free from her slavery and the Astimata Kingdom anointed her the crown princess.
  • Chaste Heroine: She is very innocent about romance and love, even having difficultly describing what a kiss is. This stunned some of her classmates at how little she knew about love.
  • Clingy Jealous Girl: She really does not like other women getting too close to Lux. By the time of episode 12, she's become resigned to the fact that she's part of a Battle Harem; however, she's not quite as eager to share Lux as the rest of the girls. She both wants to be the primary Love Interest, and while she doesn't seem to begrudge the others for being affectionate with Lux, she really can't stomach them doing so right in front of her. It's so bad she draws a sword on Lux to demand he proclaims who he loves most, which is something he doesn't even get a chance to answer.
  • Combining Mecha: Her Over Unit technique allows her to equip Tiamat with general-purpose Drag-rides as weapons and armor.
  • Dark and Troubled Past: Before the coup, she was captured by the Empire to be used as blackmail. When Count Atismata did not try to save her, her captors made her choose to either die or live and become an assassin for the Empire. Not brave enough to take her own life, she chose to live and was branded with the mark of the Empire. Soon after, the coup happened and she was rescued.
  • Defrosting Ice Queen: She's antagonistic towards Lux when they first meet, hating him for seeing her Slave Brand. After he protects her from an Abyss, she quickly opens up and befriends him.
  • The Engineer: She's the chief of the atelier for Drag-Rides, being very skilled at repairing and modifying them for her age.
  • Faux Action Girl: While she is in no way incompetent or weak, (once having taken out a wing of Kreutzer's mercenaries off-screen), her on-screen battles have her so outclassed, that she needs to be rescued the vast majority of the time. Although she does get to kill Hayes, the most powerful antagonist yet shown, in single combat in the light novel. This is subverted in Volume 12, where she fuses a Drake, Wyrm, and Wyvern to Tiamat in order to defeat the Dragon Marauders' commanders.
  • Foil: To Lux. They are both very similar, yet vastly different. Both suffer from incredible Survivor's Guilt as a result of the fall of the Empire. Both are essentially slaves. While Lisha has a brand on her belly, Lux is forced to wear a collar. Both have faced horrible betrayal and abandonment, as well as personal loss, and both still strive to make their home country a better place, despite all the grief and suffering they've endured, and still think they're not good enough for the job. While Lisha has the full support of the public, from the beginning, Lux is forced to take on odd jobs and is hounded by everyone.
  • Gravity Master: Tiamat's Divine Raiment <Suppressor>
  • Hair of Gold, Heart of Gold: Once you get to know her, she's easily the sweetest and kindest girl in the whole series.
  • Heroic Sacrifice: Subverted in Volume 19. Ouroboros sets a rule where any attack will cause the attacker to take twice as much damage. Despite knowing that the reflected damage will kill her, Lisha uses <Suppressor> on Ouroboros and damages it to the point where it can't use its Divine Raiment. However, Lux uses <Reload on Fire> to slow down the reflected attack long enough to get Lisha out of her Drag-Ride.
  • Heroic Self-Deprecation: She has low self-esteem, and she doesn't think of herself as a princess because she feels unworthy and unqualified.
  • I Cannot Self-Terminate: When given the choice of suicide or slavery, she chose slavery because she could not bring herself to commit suicide.
  • In-Series Nickname: Called "Lisha" for short.
  • Intimate Marks: She was branded with the Arcadia symbol near her groin.
  • Lady and Knight: The Bright Lady to Lux's White Knight.
  • Loners Are Freaks: It has been stated by her classmates that she is a misanthrope and that she didn't even applied for a maid to attend to her due to this.
  • Made a Slave: The corrupt nobles of the Empire made her one because her father chose to go through with the coup rather than come to her rescue. The complete and utter destruction of the Empire allows her aunt to free her. Sadly, the bad guys don't hesitate to bring this up in attempts to break her.
  • Ms Fix It: She usually repairs Lux's Wyvern after a battle. She also tries to convince Lux to let her redesign it to her taste, such as adding a drill to it.
  • Naked First Impression: Her first meeting with Lux has him accidentally falling in the women's bath and rescuing her from debris while she's bathing. While she had more than enough reason to be angry, she was especially so because Lux saw her Slave Brand.
  • Naked on Arrival: Her first appearance has her naked in the bathhouse where Lux fell in.
  • Nephewism: After her father died, she was adopted by her aunt Raffi who became the queen of the New Kingdom as the princess.
  • Parental Abandonment: Her mother died when she was young due to illness, her father chose to abandon her after she was kidnapped, and later he died during the war along with her sister.
  • Parental Neglect: She said that her father always acted indifferent towards her, and for this reason, she didn't like him. Plus he abandoned her.
  • Pervert Revenge Mode: She seems to have an extreme one after Lux accidentally falls into the bathhouse, even though the headmaster and most of the other students are more forgiving. This is subverted. While she's certainly not happy with the ecchi hijinks, Lisha was more concerned that Lux saw her Slave Brand and wanted to silence him to protect her secret.
  • Pretty Princess Powerhouse: This lovely princess is usually at the frontlines in every fight.
  • Rapunzel Hair: Her side-ponytail goes down to about her waist.
  • Red Baron: Nicknamed "Scarlet War Princess".
  • Red Eyes, Take Warning: Double Subverted. Yes, her eyes are naturally red but she is a big sweetie once you get to know her. However, she is still a competent Drag-Knight and will not hesitate to jump into battle.
  • Rescue Introduction: She first meets Lux when he saved her from the falling debris of the bathroom's ceiling.
  • Rescue Romance: She falls for Lux, hard, after he saved her life, twice. First, when their duel was interrupted by an Abyss, and second when he came to her aid against Velvet Barth.
  • Royals Who Actually Do Something: The crown princess, yet she is still one of the best Drag Knights in the series, and the top mechanic in the country, if not the world.
  • Sadistic Choice: Was a victim of this in very early childhood; slavery or suicide.
  • Shana Clone: A very toned-down example. Lisha is a petite teenage Tsundere princess with long blonde hair and Grade A Zettai Ryouiki. However, her initial animosity towards Lux, aside from justified, completely disappears once she sees what a good person he is. Afterwards, her Tsundere tendencies rarely pop up.
  • Slave Brand: Has the mark of the Empire on her belly.
  • Socially Awkward Hero: She has no problems with going on dangerous missions, but she had difficulty in just describing what a kiss is, and she basically spends most of the series having a bright red face due to being either embarrassed or nervous.
  • Stepford Smiler: She dislikes to be and to behave like a princess, but her citizens force her to be a "splendid person of character" and will blame her if she doesn't do it, so she has to "pretend" even though she is fed up with it, and she also must conceal her tragic past from others.
  • Stock Light-Novel Calamity Princess: She's nicknamed the "Scarlet War Princess" for her crimson-colored Humongous Mecha named Tiamat with great destructive power. Being an inexperienced princess of a brand new country, she is worried that she won't make a good ruler, and is especially ashamed that during the coup de tat several years prior, she was taken prisoner by the former Empire and given a slave brand that she keeps hidden. Following an originally-frosty meeting with the protagonist, Lux Arcadia (who was formerly a prince of the Empire), she sees him as her opportunity to gain influence and confidence in her future rule, eventually making him her knight. Naturally, also quickly falls in love with him and becomes extremely jealous when he attracts an Unwanted Harem of other women within the all-girls academy they attend. Particularly, her main rival is the blue-haired, emotionally-reserved Krulcifer.
  • This Is a Drill: She briefly installed a drill on Lux's Wyvern, which he immediately wanted to remove. When fighting the Dragon Marauder leaders with her Over Unit, she uses a drill to catch Vines off guard in close combat.
  • Throwing Your Sword Always Works: Subverted. She throws her sword at Velvet Barth, in her fight with him, twice. The first time she did so, it was a somewhat effective distraction to allow her to get into melee range where she would have carved him up like a turkey if not for his ability to use Quick Draw. In the second instance, she does so because she's out of options, and it's the only way she can resist his murderous intentions, though her aim was only slightly off. An inch or two upward and to the side, and it would have gone through his eye.
  • Took a Level in Badass: In Volume 18, thanks to her Baptism increasing her stamina, her Over Unit technique, and improved tactics in using Tiamat, she manages to defeat Krulcifer, who also gained various upgrades throughout the story. She also managed to defeat Lux in his Bahamut once, though he was tired and hesitant. Even when he bounces back to full strength to fight her again, she's still evenly matched with him.
  • Trauma Button: Her Slave Brand. Unfortunately, most of the villains know about it and push this button whenever they can For the Evulz.
  • Tsundere: A very downplayed version, bordering in subversion. Lisha is initially hostile towards Lux because she couldn't let him get away with seeing her Slave Brand. Once Lux protects her from an Abyss, Lisha immediately mellows out and falls completely in love with him. From then on, she acts like a subdued Sweet-type, only getting tsun-tsun when Lux pays attention to other girls.
  • Uptown Girl: Lisha is a princess and is in love with Lux, an ex-prince who has been enslaved by the new kingdom and made work as a handyman.
  • Wrench Wench: She is also the head Drag-Ride mechanic of the academy. She even created the first original Drag-Ride, the Chimeric Wyvern.
  • You Are Better Than You Think You Are: Lux says this word for word to her when he's rescuing her from Velvet.

    Krulcifer Einfolk 

Krulcifer Einfolk

Drag-Ride: Fafnir

Voiced by: Yukiyo Fujii

The adopted daughter of the Eifolk House from the country of Ymir.

  • All the Other Reindeer: Her childhood as the adoptive daughter of the Einfolk family has not been a good one. She considers it a good day if she's treated like an ornament.
  • Ambiguously Human: She looks human but she can unlock technology from the lost ruins.
  • Ascended Fangirl: For the "Black Hero."
  • Big Damn Kiss: Rewards Lux with this after he rescues her from her Bureaucratically Arranged Marriage.
  • Bureaucratically Arranged Marriage: Her adoptive family is trying to find a "proper" noble to marry her off to, her consent or well-being be damned. Fortunately, they approve of Lux after he dealt with Kreutzer. (And they found out that an alliance with the Kreutzer family would only bring harm to themselves.)
  • Combat Clairvoyance: Her Divine Raiment, <Wise Blood>, can predict where the opponent will move towards in the next few seconds.
  • Defrosting Ice Queen: Starts off cold and aloof, but warms up very quickly once she learns Lux is the "Black Hero."
  • Foreign Exchange Student: She hails from the religious country of Ymir and attends the Royal Knights Academy in the fort city Cross Feed in the New Kingdom of Atismata.
  • Happily Adopted: Subverted. She's adopted into the Einfolk family and she knows it, but aside from getting food, clothing, and shelter, purely for the sake of appearances, she is terribly verbally and emotionally abused to the point that being treated as an ornament is considered a "good day" to her. Even the family servants look upon her with disdain and try to force her into marriage without her consent or notifying her beforehand because they believe if she's notified, she'll run from it. Though in Volume 7, her father regrets distancing her from the family and reveals that he originally did so because he didn't want her to fall under the radar of rival families that want to kidnap her again.
  • Harmful to Minors: She was kidnapped by rival noble families in an ill-fated attempt to unlock the secrets of the Ruins.
  • An Ice Person: Her Divine Drag-Ride's special armament <Freezing Cannon> is a Sniper Rifle whose shots can freeze parts of her targets.
  • Lady and Knight: The Bright Lady to Lux’s White Knight.
  • Lady of War: A graceful, refined young lady whose device manifests as a rapier. She pilots her Drag-Ride with much grace.
  • Living MacGuffin: Various nobles of numerous kingdoms and former empire are after her because she can unlock the ruins and the lost technology. Lux doesn't care about any of that and treasures her as a person.
  • My God, What Have I Done?: She breaks down when she hears that she accidentally unleashed a bunch of Abyss from Ymir's Ruins, resulting in the deaths of everyone in the Gizalut family except for Mel. Though her father points out that she was actually kidnapped and forced to open the Ruins by corrupt nobles.
  • Pet the Dog: Despite really having no reason to or nothing to gain from it, especially considering that she came across as someone just exploiting Lux for her own gain at the time, she goes out of her way to help Lux with his homework, after he's had a rough day, so he could get a good night's rest. Lux considers her precious enough to risk his life for as a direct result.
  • Proper Tights with a Skirt: She wears black pantyhose as part of her uniform, fitting her noble lady image.
  • Rapunzel Hair: Her hair goes past her hips.
  • Romantic Fake–Real Turn: At first, she only made Lux pretend to be her boyfriend to convince her family to cancel her Arranged Marriage to Kreutzer. After seeing him risk his life to protect her, consistently, she falls in love with him for real.
  • Royal Rapier: Like Celestia, her device is a rapier.
  • Samaritan Relationship Starter: She was cold and aloof to Lux until she saw him come to Lisha's rescue. She's been after him ever since. It also goes both ways, considering the Pet the Dog entry.
  • The Tease: She loves to flirt with Lux, much to his chagrin. She even has no trouble sharing with other girls!
  • True Blue Femininity: A refined young lady whose outfits always feature blue in some form.
  • You Are Worth Hell: Lux doesn't say it directly, but he does profess this sentiment when rescuing her from Kreutzer.
  • You Gotta Have Blue Hair: Has light-blue Hair.

    Philuffy Aingram 

Philuffy Aingram

Drag-Ride: Typhon

Voiced by: Yurika Kubo

Lux's childhood friend.

  • Affectionate Nickname: Lux calls her Phi-chan, at her insistence.
  • Anti-Magic: Her Divine Drag-ride can negate the special attacks of other Divine Drag-rides.
  • Artificial Human: In the anime. The events of episode 8 reveal that the Empire butchered the real Philuffy in their sick experiments but somehow transferred her personality and memories to an Abyss specifically designed to look and act like her, hoping to exploit her for their own purposes. If not for Hayes' actions, the world may never have known.
  • Bad Powers, Good People: After Yggdrasil is killed, Philuffy eventually becomes capable of using her Abyss powers without losing control of herself.
  • Bare Your Midriff: Her dress gear exposes her belly button.
  • Bathtub Bonding: Snuck into the bath while Lux was there. They also used to bathe together as small children.
  • Because You Were Nice to Me: A bunch of kids were planning to push the blame for breaking a statue on her. Lux came to her defense and admitted wrongdoing instead. This would later come back to his benefit when he got thrown out of the castle, as Phillufy would be the only one to take him in.
  • Black Eyes of Crazy: When her abyss side takes over.
  • Bedmate Reveal: She sometimes sneaks into Lux's bed when he's asleep, or unconscious.
  • Boobs of Steel: She may not be the top Drag Knight, but she can still kick plenty of ass, and she has a very large chest.
  • Boxing Lessons for Superman: She learned martial arts from Magialca, one of the Seven Dragon Paladins. This was so she could control her Abyss-enhanced strength.
  • Childhood Friends: With Lux.
  • Childhood Friend Romance: Played with. Even though their cohabitation is innocent, Philuffy clearly has an interest in being more than friends with Lux and doesn't like it when other girls get in the way. Of course, she's perfectly willing to share if the other girls are.
  • Cloudcuckoolander: Most of the time, she acts distracted and barely reacts to anything, not to mention she is constantly thinking about food.
  • Combat Tentacles: Typhon can launch high tension cables that she can use to restrain, capture, and subdue other Drag-rides, even flying ones.
  • Dead All Along: According to her sister, and Lux's suppressed memories. Volume 11 reveals that Sacred Eclipse saved her with Elixir.
  • Difficult, but Awesome: Typhon's Divine Raiment is powerful and difficult to control, which is why she doesn't use it against Celestia in Volume 3, but uses it while controlled by Hayes in Volume 4.
  • Discard and Draw: After going through another Baptism and gaining the ability to further manipulate her body, Phi ejects Yggdrasil's seed from her body. This prevents her from using B-Blood mode, but also prevents anyone from controlling her with the flute.
  • The Dog Bites Back: In Volume 5, she finishes off Ragreed, a bully who tried to frame her in their childhood, by herself.
  • Dying as Yourself: She begs Lux to kill her when Hayes uses the magic flute to command her to kill Lux, and her Abyss side wakes up and tries to comply.
  • Gag Boobs: A great deal of the comedy in the show is centered around her very ample bosom.
  • Girlish Pigtails: Has her hair up like this.
  • Half-Human Hybrid: She is half-Abyss due to an experiment that implanted Abyss tissue into her.
  • Hidden Depths: Despite her airheaded personality, she successfully catches another merchant in the middle of scamming Lux and forces the cheater to trade on her terms, showing that she's a competent businesswoman.
  • Innocent Cohabitation: She's Lux's roommate, as arranged by her big sister.
  • Innocent Fanservice Girl: She's rather fond of being under-clothed around Lux.
  • I Owe You My Life: Though not aware of it, Lux's actions during the coup supposedly prevented the planned experimentation upon her. Though it turns out that the experiments were performed and she temporarily died, only to be resurrected by Sacred Eclipse.
  • Irony: She's an Innocent Fanservice Girl, that sees nothing wrong with being underclothed around Lux or sneaking into his bed, but she's the one who wears the most conservative swimsuit in public and it's clearly not a body image issue.
  • Knife Nut: Her device is a large dagger.
  • Lady and Knight: The Bright Lady to Lux’s White Knight.
  • Love Confession: She confesses her love for Lux at the end of episode 9.
  • Mundane Made Awesome: How does she kick ass in her Drag-ride? Beam weapons? Special powers and abilities? No. She kicks ass with mixed martial arts! Lux is stunned when he sees it in action.
  • One-Winged Angel: In Volume 10, she manages to use Yggdrasil's power to strengthen Typhon in a similar manner to Saniya's B-Blood Wyvern, turning it into B-Blood Typhon. This allows her to singlehandedly defeat the King of Vices, who was curb-stomping her earlier.
  • Patient Childhood Love Interest: Philuffy is completely unfazed at Lux's relationships with other girls, and always maintains her stoic, somewhat upbeat persona regardless of what happens between them. She seems to have no doubts that she can and will have Lux when everything settles.
  • Power Nullifier: Typhon can do this to other Divine Rainments.
  • People Puppet: Hayes uses her like this. Her resisting this almost kills her.
  • Purple Is Powerful: Her Divine Drag-Ride is mostly purple and her dress gear has purple trims.
  • Rose-Haired Sweetie: Big surprise there, considering she was Lux’s first real friend.
  • Sacred First Kiss: When they were both 8 or 9 years old, she ran up to him and kissed him on the lips, both because he stood up for her from the bullies that tried to frame her for breaking a statue, and because he promised her to build a country where they both could live happily as equals.
  • Shut Up, Hannibal!: She gives a glorious one to Hayes in episode 9 for berating Lux.
  • Spanner in the Works: The King of Vices counted on Lux to kill Rosa, which would make it easier for her to frame Lux as an assassin. Philuffy convinces Lux to hesitate, allowing Rosa to live and making it so that the King can only frame him for attempted assassination instead.
  • Super Senses: She has a superhuman sense of smell, which allows her to determine if antiques are the genuine article or not. She can also hear the sound of horn flutes from very far away.
  • Superpowered Evil Side: After the events of Volume 4, she can tap into her Abyss side to increase her strength and allow her to use her Drag-Ride's Divine Raiment, at the risk of being vulnerable to control by horn flutes.
  • The Symbiote: In the Light Novel, a piece of Yggdrasil in her heart is keeping her alive.
  • Tomato in the Mirror: The Philuffy whom Lux knows has a scar on her back. His roommate does not. It has yet to be revealed if she's aware of this. After the events of Episode 8, she reveals that she's well aware that she's an abyss in human form, and that she's replacing the real Philuffy who died five years ago, as a direct result of The Empire's cruel experiments. Though the light novel states that she's the real Philuffy and implies that the scar was healed when she received Elixir from Sacred Eclipse.
  • You Gotta Have Blue Hair: She has light pink hair.

    Airi Arcadia 

Airi Arcadia

Drag-Rides: Drake, Jormungandr

Voiced by: Ari Ozawa

  • A-Cup Angst: She doesn't have any problems with Lisha or the others and thinks Philuffy is an aberration, but she's clearly and immediately self-conscious standing next to Relie Aingram in a bikini, and covers her chest in embarrassment and annoyance. The fact that she's wearing a very childish swimsuit at the time doesn't help.
  • Clingy Jealous Girl: More than princess Lisesharte. While Lisha eventually becomes resigned to the fact that she's in a Battle Harem, due to knowing full well how pragmatic, political, financial, and martial pressures don't give Lux any choice in the matter, only demanding that Lux make her the favorite and that the others don't rub their affection for him in her face, Airi is completely relentless in berating him for having any girl show affection for him openly. Although she'll come down on Relie Aingram like a ton of bricks first if said affections are a result of one of her tricks, she will still come after Lux later. Heck, one chapter of the light novel had her go into an existential panic merely on the rumor that Lux had one girlfriend and was actively dating.
  • Curtains Match the Window: Like all members of her family.
  • Deal with the Devil: She makes a contract with the Turkhimes Paladin, Soffice Xfer, in order to avoid being used as a hostage against Lux. She is also forced to use a Grand Force to activate the Moon Ruin, allowing Soffice to hold the kingdom hostage.
  • Ill Girl: Was this when she was younger during the time of the Empire. She is much healthier in the present.
  • I Owe You My Life: Like Lux, she owes her very existence to Philuffy's family.
  • Little Miss Snarker: While she likes her brother, she's not afraid to berate him.
  • Little Sister Heroine: When Lisha draws a sword on Lux in episode 12 and demands to know who he loves during the Lover Tug-of-War, Airi officially throws her hat into the ring, to Lux's obvious chagrin.
  • Mission Control: Due to her weak body, she's relegated to battlefield logistics. In Volume 17, she pilots a Drake that has its functions watered down, allowing her to use its radar to support her allies without physically straining herself. Unfortunately, she's incapable of using it for self-defense. Similarly, in Volume 19, she uses Jormungandr solely for its radar.
  • Ms. Exposition: Explains her brother's abilities to anyone who's listening. Doesn't really help them since her brother's done dealing with them before they can react anyway.
  • Satellite Character: So far, she hasn’t shown any distinctive attributes aside from her interactions with Lux.
  • Tears of Joy: She wipes away a single tear and smiles with joy and pride at her brother being officially recognized as Lisha's knight in episode 12 and Lux holding Lisha's hand. This is probably the only time in the series where she isn't having a jealous fit over Lux being affectionate with a girl.
  • This Looks Like a Job for Aquaman: She's had precisely one scene (at least in the anime) where she actively contributes to Lux's war effort. She uses the abyss whistle that Lux confiscated from Velvet Barth to "overwrite" Hayes's commands on Philuffy, thus allowing Philuffy to come to aid Lux and the others in fighting Ragnarok, forcing Hayes to retreat.
  • Tragic Dream: She once wanted to be a Drag-knight and her aptitude count was high, but she lacked the physical strength and stamina to pilot a Drag-Ride effectively.
  • The Unfavorite: The Emperor considers her and Lux to be failures, and he has no problem using her as a hostage.

    Celestia Ralgris 

Celestia Ralgris

Drag-Ride: Lindworm

Voiced by: Risa Taneda

The daughter of one of the Four Great Nobles, the Student President, leader of the academy's Knight Squadron, and known as the academy's strongest Drag-Knight.

  • The Ace: The best Drag-Knight in the school. To prove it, she nearly beats Lux when he uses his modified Wyvern until a Ragnarok interrupts the battle. She later beats Saniya and her two allies by herself. After Lux becomes one of the Seven Paladins for Atismata, she becomes his aide.
  • The Atoner: She tries to prevent Lux from going to battle to atone for accidentally starting a chain of events that ruined his childhood. Luckily, he assures Celestia that she has nothing to apologize for.
  • Boobs of Steel: Is it really any surprise the academy’s top Drag-Knight also has a large chest? Lux even ends up accidentally groping her in episode 10.
  • Charles Atlas Superpower: Her stamina is far higher than most other Drag-ride pilots of both genders, to the point where a warm-up for her is Training from Hell for everyone else.
  • Contralto of Danger: Played with. In battle, she has a deep, confident tone. Otherwise, her voice is warm and gentle, almost musically soft, especially if she is with Lux.
  • Cruel to Be Kind: The whole reason for her harsh attitude was to keep Lux out of danger.
  • Did They or Didn't They?: In Volume 20 Chapter 1, Lux and Celestia spend a night together and make out, but both are naked the next morning, making it ambiguous if they did the deed.
  • Does Not Like Men: Is known as being a man-hater. She actually isn't and is only using it as an excuse to keep Lux out of battle and to hide her shyness around males around her age.
  • The Dog Bites Back: In Volume 5, she defeats Saniya and two other B-blood users by herself.
  • Endearingly Dorky: Celestia. Lux, states that it's her awkwardness that makes her cute.
  • Et Tu, Brute?: She takes Saniya's betrayal pretty hard and takes it upon herself to defeat her. She manages to do so in the final episode.
  • Hair of Gold, Heart of Gold: Despite pretending to be cold, her true personality is as noble and benevolent as her blonde hair would suggest.
  • Hidden Heart of Gold: She seems stubbornly insistent on removing Lux from the academy despite all the times he helped them. It turns out she was actually concerned for Lux's safety the whole time.
  • I Work Alone: Due to her role as the leader of the school's Knight Squadron and her guilt over Lux's grandfather getting arrested, she doesn't believe she can rely too much on others for help. She drops this at the end of Volume 3, where she's more willing to share her burdens with Lux and the rest of the school.
  • It's All My Fault: Celestia is burdened with the guilt of ruining Lux's life.
  • Jousting Lance: Lindworm's main weapon.
  • Lady and Knight: The Bright Lady to Lux’s White Knight.
  • Light Is Good: Her name means "heavenly" in Latin, and her white and gold Drag-Ride gives her the appearance of an angel.
  • Nice Girl: When Lux gets to know her real self as "Luno", Celestia turns out to be one of the sweetest girls he has come across.
  • Nice Job Breaking It, Hero!: She revealed the Empire's corruption to Lux's grandfather Wade Roadbelt, who confronted the emperor about it. Unfortunately, the emperor then banishes Lux's side of the family.
  • Noodle Incident: During Volume 4's beach trip, the other third years ban her from cooking because of one of her previous cooking attempts during their expedition in the capital. The only explanation they give for this incident is that she broke things, and nothing more specific than that.
  • Royal Rapier: Lindworm's Sword Device.
  • Shameless Fanservice Girl: She once demanded a massage, naked, expecting Lux. She was shocked and disappointed when "Luno" showed up.
  • Spell My Name with an "S": "Celestia" or "Celistia"?
  • Super Reflexes: After receiving Baptism, her reflexes are enhanced beyond other Baptism recipients.
  • Teleportation: Lindworm's Divine Rainment can teleport within a certain range.
  • Unwitting Instigator of Doom: By telling Lux's grandfather about the corruption of the old empire, she is the very person who ended up starting the events that lead to the story.
  • Walking Spoiler: Those white spaces aren't for show you know. She's indirectly responsible for the current state of Lux's life and is also the one who kicked off the storyline.

    Yoruka Kirihime 

Yoruka Kirihime

Drag-Ride: Yato-no-kami

An assassin for the Old Empire, who now works for Hayes.

  • Abusive Parents: Her own father not only called her a bloodless monster but forced her into the assassin business.
  • All for Nothing: She becomes the Empire's top assassin to spare her little brother, and to save their own skin, the very nobles who contracted her turn over her little brother for decapitation and present his head to her before siding with the new kingdom. Small wonder she doesn't like the country much.
  • Aloof Dark-Haired Girl: A cold, efficient assassin with long, flowing black hair. When she's with Lux, however, it's an entirely different story.
  • Assassins Are Always Betrayed: In a truly heartbreaking way. She is forced to become an assassin by her own father, and that's bad enough, but then she's forced into the service of the Arcadia Empire, and while she's away they kill her little brother. Purely for self-promotion.
  • Bad Powers, Good People: Elixir is known to drive people insane, yet she ends up becoming one of Lux's allies while still using that power. Though in her case, she didn't take enough of it to drive herself insane and she received proper surgery from Hayes to use it more safely.
  • Because You Were Nice to Me: In her whole life, only two people have treated her kindly: her little brother and Lux himself. And for that, she loves them both.
  • Best Her to Bed Her: Lux wants to make her one of his queens, but she refuses because she believes she needs to devote herself to being his bodyguard. She states the only way to change her mind is if he defeats her in Drag-Ride and ground combat, in addition to making sure he never lets his guard down.
  • Beware the Silly Ones: She has plenty of funny ecchi moments before and after her Heel–Face Turn, but she still would have defeated Lux in Volume 5 if she didn't lose focus.
  • Casual Kink: In Volume 9, she reveals very strong masochistic tendencies, to Lux's dismay. When he tells her that he has to punish her (for attacking another student in order to protect him), she waits for him in a dungeon, naked except for black panties, wearing a collar with a chain binding her to the floor, wooden shackles on her wrists, and a seductive smile. Lux is so freaked out he immediately abandons any idea of punishing her.
  • Creepy Child: By her own admission, her father claimed she was "talented at assassination" since birth. Her younger brother is the only one she remembers treating her like a person, at least before meeting Lux.
  • Dark Action Girl: She worked as an assassin for the Old Empire and worked with Hayes to destroy the New Empire’s capital. It’s only with Lux’s help that she switches sides.
  • Dark Is Evil: Black hair, black outfit, and the name of her Drag-Ride translates to "God of the Night Sword." Subverted after her Heel–Face Turn.
  • Dark Is Not Evil: After her Heel–Face Turn.
  • Defeat Means Friendship: Or Love Interest in her case.
  • Easily Forgiven: Lux and his haremettes are quick to forgive her after she helps them save the New Kingdom's capital.
  • Explosive Overclocking: She can use <Spell Code> on herself to activate Overlimit by hacking into her Drag-ride's system.
  • Flash Step: This is what makes her so dangerous as an assassin. Either on foot or in a Drag-ride, she has mastered a technique that allows her to move unnoticed just outside her target's area of perception. While Lux has learned how to counter it, at great difficulty, while using Bahamut's advanced systems, he's still no match for her on foot.
    Yoruka: "Concentration is like breathing. No matter how carefully you focus, it will eventually slip, and that's when I strike."
  • Freudian Excuse: And it's a good one. Her "employers" turned on her and broke their end of the Leonine Contract they had her under by killing her little brother.
  • Godiva Hair: Her hair conveniently covers her breasts in Volume 9's casual kink illustration.
  • Graceful Loser: Takes her defeat to Lux with surprising calm because she is in love with him.
  • Hack Your Enemy: Her <Spell Code> Divine Raiment can hack an enemy's Drag-Ride and take control of it. She can also use it on herself or her allies as a shortcut to activate Overlimit.
  • Heel–Face Turn: In episode 12, Yoruka destroys the core of Hayes's giant before it can fire on the New Kingdom's capital.
  • Hypercompetent Sidekick: To Hayes in terms of Drag-ride skills. Despite both using Baptism, Yoruka uses her assassin skills to nearly defeat Lux despite her Drag-ride's lesser firepower while Hayes struggles against Lisha despite having a far stronger Divine Drag-ride.
  • I Gave My Word: She honors her assassin contract to the Arcadia Empire, despite the fact that it no longer exists because she promised her little brother to do so. Being beaten by Lux in single combat allows her to turn on Hayes and save the Kingdom's capital.
  • Katanas Are Just Better: Her Sword Device is a katana that sets off flames when summoning her Drag-Ride. It's also sharp enough to slice a Ragnarok core in half.
  • Lady and Knight: The Black Knight to Lux’s Bright Lord. No, really.
  • Lady Macbeth: Attempts persuade Lux into joining Hayes's side by using her feminine wiles. Not only Lux doesn't fall for it, he convinces her to switch sides by appealing to her better nature.
  • Laughably Evil: Before her Heel–Face Turn, she's one of the few antagonists to have humorous moments, such as when she invaded Lux's personal space in order to serve him and convince him to join Hayes. Unlike La Krulshe, this is due to her own personality rather than Amnesiac Dissonance.
  • Magical Eye: Her left purple eye received Baptism. It allows her to detect someone's presence, perceive the wavelength of the opponent's consciousness, and understand the subtleties of their heart.
  • Marionette Master: Yato-no-kami can hijack another person's Drag-Ride, which she uses to make Lisha fire on the audience and sow discord among the kingdom.
  • Morality Chain: Her own little brother filled this role. Lux can also qualify.
  • My Greatest Failure: She noticed that Koto's vassals were untrustworthy, but didn't take the initiative to stop them, which is why she wants to kill Singlen before his schemes against Lux go too far.
  • Noodle Incident: How did she wind up in prison? Either it took an army to get her in, which begs the question of why an alert and wanted posters didn't go up immediately when she was broken out. Or she went in there willingly, which begs the question of why she'd want out.
  • No Sense of Personal Space: At least when Lux is concerned.
  • Not So Different: From Lux. They are both the last heirs of a fallen kingdom, betrayed by people they thought they could trust. But while Lux remained a good person, Yoruka became embittered and cynical. Her redemption is achieved when Lux realizes she is as much as a victim to the Arcadia Empire as he was.
  • Oblivious to Love: She believes that Lux sees her as a tool and wouldn't bat an eye if she sacrificed herself for him, not realizing that he considers her a loved one.
  • Professional Killer: She worked as one for the Old Empire to care for her ailing younger brother.
  • Raven Hair, Ivory Skin: As one of the few characters with a remotely Asian background, she has black hair and fair skin.
  • Reformed, but Not Tamed: After her Heel–Face Turn, she's still used to being an assassin, to the point where she secretly plots to kill Singlen for manipulating Lux.
  • Roaring Rampage of Revenge: Though she doesn't tell Lux, the stylized symbolic flashback indicates that she hunted down and killed, by beheading, each and every one of the traitorous nobles who sold out her kingdom to The Arcadia Empire, and thought killing her brother and presenting his head to the Emperor was a good idea
  • Shipper with an Agenda: She ships Lux with as many girls as possible, including herself, with the stated intention of producing as many heirs as possible.
  • Showgirl Skirt: She leaves the front of her kimono's lower half-open so we can see her legs.
  • Subordinate Excuse: Being a servant of the Old Empire, she recognizes Lux as her master and it's clear she has feelings for him.
  • Super Mode: She can enter a state known as "Baptism", which seems to increase her concentration and speed. She almost defeats Lux with this until her own concentration is broken from talking about her past.
  • The Tease: In episode 10, she sneaks up on Lux in the bathhouse and offers to wash him, even pressing her breasts against his back.
  • Tyke-Bomb: By her own admission, her father saw her as good for only one thing, becoming a skilled assassin. Only her little brother saw her as a person and treated her kindly.
  • The Unfavorite: Her parents clearly favored her ill little brother over her. She doesn't resent him for it, since he always treated her kindly, without exception, even knowing what she was raised for.
  • Warrior Princess: She was originally a princess of Koto, a small island country.
  • We Have Become Complacent: Defied. After Lux passes her final challenge by besting her in both Drag-Ride combat and ground combat, she occasionally attacks him to ensure he doesn't get rusty.
  • When She Smiles: The final episode sees her delivering a genuinely tender, non-threatening smile. Just look!
  • The Worf Effect: Despite using both Overlimit and Baptism, along with being more skilled than Lux, she loses against Singlen when the latter uses Baptism.
  • Yandere: Played realistically and then subverted. She can't decide what she wants more, to love Lux, or kill him for rejecting the Old Empire. After she's beaten, she decides to "love" him to Lisasharte's chagrin, though Yoruka is willing to share him with the other haremettes.
  • You Can't Go Home Again: Twice. First, her home country is conquered by the Arcadia Empire, and then the Empire falls to a coup and gets reformed into the Atismata Kingdom.
  • You Remind Me of X: Admits Lux reminds her of her brother. When Lux is about to beat her, she catches a small glimpse of her brother in Lux’s place.

How well does it match the trope?
