One of the three teams representing Ordesia Empire
Voiced by: Makoto Furukawa
The Hero of our story. Three years ago he won the Blade Dance as Ren Ashbell. Now, having lost his contracted spirit, he is lured to Areshia Spirit Academy by Greyworth to compete in the Dance once more.
The Antichrist: As the reincarnation of the Demon King, he is potentially this.
Brought Down to Badass: Three years of inactivity greatly weakened his abilities as an Elementalist. However, he's still much stronger than a lot of Elementalists.
Submissive Badass: Willing follows Claire's orders. Though some compare it to putting up with a spoiled kitten.
Battle Harem: He has one, though surprisingly not everyone in his harem is in it.
The Berserker: When he starts to accept the power of the Demon King sleeping within him, he becomes this.
Butt Monkey: Gets blamed for pretty much everything, with nearly every girl in the world believing that he's a complete pervert.
Chronic Hero Syndrome: Jio exploits this by gunning for his teammates, which usually leads to Kamito tanking powerful attacks in order to protect them.
Clueless Chick Magnet: 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 Restia and Greyworth. It's basically the only way he knows to interact with them.
Conspicuous Gloves: 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.
Cool Sword: He has two of them. Both of which turn into beautiful girls.
Lightning Bruiser: 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.
Only Sane Man: Is often completely dumbfounded by the antics of his friends.
Red Baron: Was known as the Strongest Blade Dancer during his days as Ren Ashbell.
Sealed Inside a Person-Shaped Can: 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.
Willfully Weak: 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.
A Date with Rosie Palms: Tried massaging her chest to make it grow. Kamito walks in and immediately closes the door and walks away.
Action Girl: While she isn't on Kamito's level, she is an extremely skilled combatant in her own right.
Broken Pedestal: 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 Fiery Redhead.
Freudian Excuse: 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.
She uses a normal one to direct Scarlet in battle. And to hit Kamito.
Terminus Est/"Est"note Terminus Est Zwei
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.
Absurdly Sharp Blade: Especially against other swords, as Est is a Steel Sword Spirit of the highest class, most opposing swords are destroyed by her on contact.
Anti-Magic: Est has the ability to completely negate and repel magic. Everything she negates is actually absorbed into herself, and once it reaches a certain point, will be transferred to her master, killing them.
Big Eater: Loves to eat, especially sweets. Once, she ordered and consumed all the sweets on a restaurant menu. 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.
Brought Down to Badass: 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.
Innocent Fanservice Girl: 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.
Laser-Guided Amnesia: Due to her incomplete contract with Kamito, her memories are fragmented and she can't recall much of her past.
Legendary Weapon: 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. She really is the Sacred Sword.
Light Is Not Good: Est certainly is good, the way her powers work on the other hand...
Morph Weapon: Can freely change shape into any type of sword in order to suit her master's needs.
Split Personality: 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.
Undying Loyalty: To Kamito. 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.
Unholy Holy Sword: 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.
Scarlet/Scarlet Valkyrie, Ortlinde
Claire's hellcat contract spirit. She is a spirit passed down the Elstein family.
A student at the Areshia Spirit Academy and the current leader of the academy's Sylphid Knights. A serious girl whom is charged with maintaining order and discipline to the students, as well as protecting the citizens from hostile spirits.
Boobs of Steel: The strongest of the main (human) female cast in physical combat. Also coincidentally, by far the biggest bust.
Defrosting Ice Queen: She started out as an antagonist. She's now the team member who tag teams with Kamito the most.
Ellis's older-step-sister and former leader of the Sylphid Knights.
Brought Down to Normal: After Kamito defeats her for the second time and removes the Cursed Armament Seal from her body, she ended up losing all her abilities as an Elementalist. It may be years before her power returned, if it ever will.
Happily Adopted: She was adopted into the Fahrengart family and Ellis treats her like she is her real older sister.
Powered Armor: What her elemental waffe, Silent Fortress, originally took form as three years ago.
Power at a Price: In order to gain more power and face Ren Ashbell again, she ended up using a Cursed Armament Seal. While it did end up greatly increasing her power, it also rapidly destroyed her body and altered her personality.
Put on a Bus: After her defeat in Volume 3, she was sent to Balsas Prison.
The Bus Came Back: She reappears 10 volumes later in Volume 13, being imprisoned next to Jio Inzagi and Vivian Melosa.
Secret Keeper: She realized that Kamito is really Ren Ashbell after being defeated by her/him the second time.
Leader of the Sacred Spirit Knights. During the previous Blade Dance, she made it to the final round only to be defeated by Ren Ashbell/Kamito and is often regarded by him as his strongest opponent.
Enemy Mine: In the 13th Volume, she fought along side Kamito still unaware that he was the Ren Ashbell that defeated her.
Knight Templar: She will follow the orders of her nation without question. During the Blade Dance, she was ordered to kill Restia and attempted to do so, despite not knowing the reason and that doing so would go against the rules of the Blade Dance.
Red Herring: Kamito would mention in nearly every volume that during the previous Blade Dance, she was by far his toughest opponent and that he's not eager to have to face her again. Even an encounter with another team from the Sacred Spirit Knights taunted him about facing her. Despite all this foreshadowing, not only do they not fight during the entire Blade Dance, they never even encountered one another until the closing ceremony. Lampshaded before Scarlet defeats her, as she expresses her dismay that she cannot be defeated here and she still needs to resume her duel with Ren Ashbell and win the Blade Dance.
The Unfought: To Kamito in the current Blade Dance. Despite nearly every volume giving mention to her and everything foreshadowing their upcoming battle.
The Worf Effect: After being mentioned as Kamito's strongest opponent, spending most of a volume defeating Restia and hunting down/curb stomping Claire, she was almost immediately defeated to show off the power of the awakened Scarlet.
This Cannot Be!: Before being defeated by the awakened Scarlet, she expresses her dismay that she cannot be defeated now, since she still needs to resume her duel with Ren Ashbell and win the Blade Dance.
Fire Elemental Lord «Volcanicus»
The lord of fire spirits. Often depicted as a warrior wielding a blazing sword.
Wind Elemental Lord «Belphal»
The lord of wind spirits. Often depicted as a boy with kind eyes.
Earth Elemental Lord «Lode Gear»
The lord of earth spirits. Often depicted as an iron mallet-wielding giant.
Water Elemental Lord «Iseria Seaward»
The lord of water spirits. Often depicted as a woman hugging a water jug to her chest.
A demon sword, she is the most powerful Darkness Elemental Spirit in the world and takes the form of a girl. She was Kamito's previous contracted spirit, but she disappeared three years ago for reasons unknown. Discovering her whereabouts is Kamito's main goal. She is actually the embodiment of the will of Ren Ashdoll, the Darkness Elemental Lord. Her goal is to ensure the awakening of the current vessel of Ren Ashdoll's power. ie: Kamito.
Anti-Magic: Her black dress actually possesses powerful anti-magic properties, but is completely powerless against Holy Elemental attacks.
Sink or Swim Mentor: She wants to get Kamito back to his prime and accomplishes this by teaming up with or manipulating his immediateantagonists. However, she drops this role when Rubia and Laevateinn prove to be unbeatable without her and Est's combined power.
Theres No Kill Like Overkill: Uses Hell Blast, the most powerful Darkness Elemental spell, for everyone including Elementalists, demons, and degenerated spirit ghosts.
An Elementalist using Kamito's Ren Ashbell identity and is participating in the next Blade Dance. One of Kamito's objectives in the next Blade Dance is to figure out what she's up to. She is eventually revealed to be Rubia Elstein, the Calamity Queen and Claire's older sister. She joined the Blade Dance in order to awaken Kamito as the Demon King.
Broken Pedestal: She started losing faith in the Elemental Lords after the destruction of Dylus along with countless incidents. Her faith was on the verge of shattering completely after the Flame Elemental Lord demanded Claire's sacrifice, and was completely lost after witnessing the corruption on the Flame Elemental Lord's throne.
Brought Down to Badass: After her contract with Laevateinn was severed, she lost all her ability as an Elementalist but still retained her Elstein Flames. Claire sealing the Demon King within Kamito also greatly reduced her power.
Reincarnation: She is the reincarnation of the Sacred Maiden, a power bestowed by the Five Great Elemental Lords in response to the Demon King's awakening.
Rescue Romance: She falls for Kamito after he saved her from Laevateinn, though she didn't realize what she felt meant.
Shoot the Shaggy Dog: She gave up everything and was willing to lose both Claire and her own life in order to revive the Demon King. She succeeded, and then it's abruptly undone essentially because Claire refuses to cooperate. Then she throws everything she has at Kamito in a last-ditch effort to re-awaken him, and he kicks her ass without the Demon King's power. Jerk Ass she may be, but everything she had fought for was unraveled in front of her because Claire and Kamito basically said "no".
And the worst part? It was never going to work in the first place. She wants to kill the Elemental Lords to eliminate The Corruption, but the Demon King is also corrupted. If Kamito had awakened, he would have destroyed the world in exactly the same method that she was trying to prevent.
Strong as They Need to Be: As the reincarnation of the Sacred Maiden, her strength is directly proportional to the power of the current Demon King. As the Demon King grows in power, so will her own. On the other hand, the weaker the Demon King becomes, the weaker she will become in turn.
Well-Intentioned Extremist: She realized the insanity of the Elemental Lords along with the corruption and seeks to awaken Kamito, the current incarnation of Ren Ashdoll so that he may kill them and separate the spirits from the human world. The resulting chaos will possibly kill millions of people, but humanity would be saved as a result.
You Have Outlived Your Usefulness: After her defeat in the Blade Dance, Hierarch-possessed Sjora Kahn decided to silence her, but was ultimately prevented by Muir and Lily.
