[[folder:Ordesia Empire]]
!Areshia Spirit Academy
!!Team Scarlet
One of the three teams representing Ordesia Empire
!!!Kamito Kazehaya
->Voiced by: Creator/MakotoFurukawa

TheHero of our story. Three years ago he won the [[TournamentArc Blade Dance]] as [[GenderBender Ren Ashbell]]. Now, having lost his contracted spirit, he is lured to Areshia Spirit Academy by Greyworth to compete in the Dance once more.
* TheAntiChrist: [[spoiler:As the reincarnation of the Demon King, he is potentially this.]]
* AntiAntiChrist: [[spoiler:He's trying not to lose himself to his powers.]]
* AttractiveBentGender: Oh ye gods.
* BroughtDownToBadass: Three years of inactivity greatly weakened his abilities as an Elementalist. However, he's still much stronger than a lot of Elementalists.
* BattleHarem: He has one, though surprisingly not everyone in his harem is in it.
* TheBerserker: [[spoiler:When he starts to accept the power of the Demon King sleeping within him, he becomes this.]]
* ButtMonkey: Gets blamed for pretty much everything, with nearly every girl in the world believing that he's a complete pervert.
* ChronicHeroSyndrome: [[spoiler:Jio exploits this by gunning for his teammates, which usually leads to Kamito tanking powerful attacks in order to protect them.]]
* CluelessChickMagnet: To an extent. He flirts with girls and teases them for fun, but it doesn't occur to him that they could end up having serious feelings for him. Justified as the two women he had interactions with before were [[TheTease Restia]] and [[TheGadfly Greyworth]]. It's basically the only way he knows to interact with them.
* ConspicuousGloves: He always wears gloves on his left hand in order to hide the spirit seal of Restia. This is because any Elementalist whom sees it would immediately realize that he's Ren Ashbell.
* CoolSword: He has two of them. Both of which turn into beautiful girls.
* DiagonalCut: Violet Flash, a single strike so fast most opponents can't see it. [[{{Irony}} Also the attack Greyworth beat him down with on their first meeting]].
* DeadPanSnarker: Any time he isn't teasing someone.
* DramaPreservingHandicap: He's often weakened or wounded in some way so he doesn't immediately curb stomp most of his opponents.
* DualWielding: His original style.
** [[spoiler:Gloriously brought back when he wields both Est and Restia.]]
* EmbarrassingNickname: ''The Demon King of the Night'', much to his dismay.
** Eventually expands to [[RefugeInAudacity ''Demon King of the Daytime'']], [[OverlyLongGag ''Demon King of the Afternoon'']], [[RuleOfThree ''Demon King of the Morning'']]....
*** After the Blade Dance, he also received the name the ''Sex Elemental Lord''.
* EnemyMine: In the 13th Volume, [[spoiler:fought along side Luminaris Saint Leisched]].
* EverythingsBetterWithSpinning: Shadow Moon Waltz, [[OneManArmy an anti-army technique.]]
* HeroWithBadPublicity: Unfortunately for him, [[MaliciousSlander he is subject to being called a pervert]]. It even spread to other countries.
* HeroWorshipper: Much to his dismay, nearly every Elementalist of his generation views his Ren Ashbell persona as such, with the tales and exaggerations reaching the point of FolkHero[=/=]PuritySue levels. This is one of his reasons for not revealing his secret, even to his friends, so [[BrokenPedestal he wouldn't break their dreams]].
* LightningBruiser: Back during his days as Ren Ashbell. Just about the only opponents that could give him a hard time were Elementalists with Holy Elemental spirits, as Restia, being of Darkness Element, is at a serious disadvantage against.
* MasterSwordsman: ''Was'' one back in the day as Ren Ashbell.
** Regains his former power over the course of the series, and [[spoiler: ''surpasses'' it when he [[DualWielding dual wields Restia and Est]]]]
* OnlySaneMan: Is often completely dumbfounded by the antics of his friends.
* RedBaron: Was known as the ''Strongest Blade Dancer'' during his days as Ren Ashbell.
* SealedInsideAPersonShapedCan: [[spoiler:Before her defeat, Ren Ashdoll sealed her power within humanity itself and would manifest onto individuals throughout history. All have either gone crazy or were destroyed by her power. All, except for Kamito.]]
* SpamAttack: [[OverlyLongName Bursting Blossom Spiral Blade Dance]], his finishing move. The number of hits in the attack varies.
** This technique was designed to kill [[PhysicalGod Archdemon-Class Spirits]]. Even nerfed as he is, few people take it and survive.
* SubmissiveBadass: Willing follows Claire's orders. Though some compare it to putting up with a spoiled kitten.
* SupernaturalMartialArts: The Absolute Blade Arts techniques he learned from Greyworth.
* TheTease: Is not above teasing the girls, especially due to their lack of knowledge around men.
* TranquilFury: when he is truly pushed past his breaking point.
* UnwantedHarem: Oy vey. [[{{Tsundere}} Claire]], [[EverythingIsBetterWithPrincesses Fianna]], [[EquippableAlly Est]], [[LadyOfWar Ellis]], [[{{Ojou}} Rinslet]], [[{{Yandere}} Muir]], [[DarkMagicalGirl Restia]], and [[WorthyOpponent Leonora]]. And these are only the primary characters.
* WillfullyWeak:
** Despite being weakened due to his three years of inactivity as an Elementalist, he still holds back against his opponents. Justified because his true fighting style involves techniques only Ren Ashbell and Greyworth knew, so using it would reveal that he is Ren Ashbell.
** Eventually he starts using them anyway, and tries to pass it off as having studied under the same master as Ren Ashbell. It works... for a while.

!!!Claire Rouge/Claire Elstein
->Voiced by: Ibuki Kido

A young girl Kamito meets on his way to the Areshia Spirit Academy. After seeing Kamito form a contract, she declares him her slave spirit and forces him to form a team with her. She is actually the younger sister of the Calamity Queen, Rubia Elstein, a fact which has caused her to be ostracized from nearly everyone.

Her wish is to meet her sister and discover why she betrayed the Elemental Lords and her country.
* ACupAngst: She has small breasts.
* ADateWithRosiePalms: Tried massaging her chest to make it grow. Kamito walks in and immediately closes the door and walks away.
* ActionGirl: While she isn't on Kamito's level, she is an extremely skilled combatant in her own right.
* BrokenBird: Kamito learns that the reputation of her sister also rubbed off on her as a result of her betrayal. Because of that, she lost everything, and is extremely protective of anyone trying to take him away from her, fearing she'd lose him as well. Fortunately Kamito realizes this, and tries not to do anything too rash that would cause her to feel he'd abandon her.
* BrokenPedestal: Her sister's betrayal of the Flame Elemental Lord and the resulting consequences to her parents completely shattered her world and changed the shy, timid girl into the current FieryRedhead.
** RebuiltPedestal: [[spoiler:After learning the truth from her sister.]]
* CatchPhrase: Turn into charcoal! [-(Turn to ash)!-]
* ChildhoodFriends: To Rinslet. The feeling is mutual, not that either would ever admit it though.
* ClingyJealousGirl: Does not like seeing Kamito around other girls, whether it's Rinslet, Ellis, or even his contracted spirit Est.
* CovertPervert: Actually reads and enjoys rather risque novels.
* ExpressiveHair: Her hair tends to flail around when she's angry. This is because Elementalists can take on attributes of their contracted spirit.
* FieryRedhead: She has red hair and appropriately enough, has a short temper.
* FreudianExcuse: The reason she acts like a little brat is because she lost ''everything'' after her sisters betrayal, and was nearly universally scorned for her relation to Rubia. This happened when she was ten years old.
* LethalChef: The food she cooks resembles charcoals.
* LonersAreFreaks: She feels she has no one to rely on, mostly because of her relation to her sister who earned a very bad reputation amongst people after her betrayal and disappearance. Despite that, Kamito sees that there are people who still care about her, such as Rinslet, though they're both too proud to ever admit it.
* PlayingWithFire: Her primary element.
* ShanaClone: Fills most of the requirements of this role and like the prime example she does eventually grow out of it.
* TheRival: To Rinslet.
* SchmuckBait: Rinslet tells her that if the boy she likes rubs her breasts, they'll grow bigger. Claire has an ImagineSpot of that happening. Fianna later tells her it's not true.
* TheStrategist: Surprisingly for her [[{{Tsundere}} character]] [[FieryRedHead type]], she is the leader of Team Scarlet in more than name, and repeatedly gives out effective winning strategies.
* {{Tsundere}}: She's nearly as bad as [[LightNovel/TheFamiliarOfZero Louise]] at first, though she warms up significantly.
* UsedToBeASweetKid: Before Rubia's betrayal happened, she was an adorable little MoeBlob.
* VitriolicBestFriends: With Rinslet, though she won't admit it.
* WhipItGood: Her Elemental Waffe.
** She uses a normal one to direct Scarlet in battle. And to hit Kamito.
* ZettaiRyouiki: A bonafide Grade S. {{Tsundere}}? Check! And the GirlishPigtails too? Got it!

!!!Terminus Est/"Est"[[note]]Terminus Est Zwei[[/note]]
->Voiced by: Ai Kakuma

A Steel Elemental Spirit that takes the form of a young girl. She was sealed within a sword and is the most powerful Steel Elemental Spirit in the world.
* AbsurdlySharpBlade: Especially against other swords, as Est is a Steel Sword Spirit of the highest class, most opposing swords are destroyed by her on contact.
* AntiMagic: Est has the ability to completely negate and repel magic. [[spoiler:Everything she negates is actually absorbed into herself, and once it reaches a certain point, will be transferred to her master, killing them.]]
* {{BFS}}: Can turn into this.
* BigEater: Loves to eat, especially sweets. Once, she ordered and consumed all the sweets on a restaurant menu. [[spoiler:As a spirit, she doesn't actually need to consume human foods. Her desire to eat was due to the influence of her previous master, Areshia.]]
* BroughtDownToBadass: Due to her incomplete contract, she can't even bring out 1/10th of her true power. Just note that even in her current state, she's still fully capable of one-shotting most spirits and can completely negate all but the most powerful spells.
** It's been stated that at her full power, even the Elemental Lords were terrified of her.
* [[spoiler:CastFromHitPoints: Her powers gradually becomes this for her master.]]
* ClingyJealousGirl: Acts like this around Restia, since Kamito is '''her''' master. She also gets upset when he kisses Claire to form a contract, and says she's within her rights to kiss him as well.
* CryCute
* DarkAndTroubledPast: Est unknowingly killed [[spoiler:Areshia Idriss, her previous master, when she absorbed all of Est's stored curses throughout the years.]]
* TheDreaded: Restia mentions that even she would not dare make fun of Est if she was her original Sacred Sword self. [[spoiler:Even the Elemental Lords are terrified of her.]]
* ElementalRockPaperScissors: As a Steel Elemental Spirit, she naturally have a harder time against Shield Elemental Spirits. "A harder time" as in it takes a [[AbsurdlySharpBlade little more effort for her to cut through them]].
* EmotionlessGirl: How she normally acts.
* EstablishingCharacterMoment: When she first shows up in human form, Kamito sees her completely naked except for some thigh-high stockings. Later Rinslet has Fenrir attack him out of jealousy, only for Est to then put the wolf in its place. She also ends up bending Ellis's sword after she assumes he's being a playboy with a new girl.
* InnocentFanserviceGirl: When he wakes up in the morning, Kamito almost always discovers Est sleeping next to him almost completely naked (almost, in that she's wearing thigh-high knee socks). Justified because she's actually a spirit and her attitude towards Kamito is not much different than say, Scarlet treating Claire.
* LaserGuidedAmnesia: Due to her incomplete contract with Kamito, her memories are fragmented and she can't recall much of her past.
* LegendaryWeapon: Est is potentially ''The Sacred Sword of Severian'', the legendary sword that Areishia Idriss once used to defeat the Demon King. However, Kamito notes that there are rumors of the Sacred Sword's possible location from all over the world. [[spoiler:She really is the Sacred Sword.]]
* LightIsNotGood: [[spoiler:Est certainly is good, the way her powers work on the other hand...]]
* MorphWeapon: Can freely change shape into any type of sword in order to suit her master's needs.
* RedBaron: Known as the ''Demon Slayer''.
* SeriousBusiness: In her human form, she has no issues being completely naked other than wearing some thigh-high stockings. But if she suspects Kamito wants her to take those off, she acts as if he were asking a normal girl to strip off her underwear. He does [[LampshadeHanging lampshade]] the silliness of that logic.
* SplitPersonality: [[spoiler:As a result of her incomplete contract with Kamito, Est was split into two personalities. The current Est, with limited recollection of her past, and Sacred Sword Est, her past self.]]
* UndyingLoyalty: To Kamito. [[spoiler: Her original had this to Areshia as well. As they have become separate entities, Est's loyalty is now totally with Kamito. To drive this home, she declared that if Kamito became the Demon King, then she would be the Demon King's Sword rather than betray him.]]
* UnholyHolySword: [[spoiler:She's actually a Demon Sword. All the resentment/curses from the spirits slain by Est are absorbed by her and will eventually pass it onto her master. In the past, she unknowingly killed her previous master, Areishia Idriss and as a result, sealed herself in seclusion in order to never harm anyone ever again. Despite this, Kamito accepted Est, and upon victory in the Blade Dance, plans on using his wish to truly turn Est into a Sacred Sword.]]
* ZettaiRyouiki: She wears knee-high socks.

The Ordesia Empire's second princess.
* BigBreastPride: She's quite proud of her large bust, and enjoys teasing Claire about it. [[spoiler:Subverted later when it turns out she was using pads, partly to hide her bloodstone, but partly because she heard men [[BuxomIsBetter like big breasts.]] Kamito tells her some men like smaller ones too, which gives both her and Claire some hope.]]
