Kamito Kazehaya Render
I'll become strong! No, we will become strong! Even more than when I was called Ren Ashbell.
~ Kamito's declaration to the world


Kamito Kazehaya is the main protagonist of Seirei Tsukai no Blade Dance, a unique male elementalist, a former assassin, a master swordsman and the reincarnation of the Demon King. Three years ago, he disguised himself as a girl under the alias Ren Ashbell to participate in the Blade Dance. He won, but due to a certain event, he abandoned blade dancing for three years, until he was called by his acquaintance Greyworth Ciel Mais to attend the Areishia Spirit Academy. She wants him to become an elementalist again, because Ren Ashbell has reappeared, even though she and Kamito are supposed to be the same person.

Attack Potency: Likely Large Building level (Defeated tournament favorite Velsaria and her spirit Dreadnought very fast, a world-renowned top-tier spirit for its almost impenetrable armor, compared to a fortress'.) | Building level (Weaker than in Ren Ashbell form. He has regained strength, but still isn't as strong because his current spirit, Est, is incomplete. He still defeated many elementalists, including a professional assassin wielding 15+ spirits, the strongest student of a rival country in a berserk mode, and a martial-arts master.) | Likely City Block level, possibly Higher (With his 2 spirits combined in a single sword, his damage output is much higher, often said to be higher than when he was Ren Ashbell. He killed many ice dragons, and fought on par with the 3rd strongest Ordesian elementalist and her powerful gravity-type spirit.) | At least Small Town level, likely higher (Fought on par with his brainwashed full-powered mentor, considered the strongest human character in the series. Defeated Laevateinn, the strongest fire spirit, and defeated the mentioned gravity-user. His empowered punches create small craters. His energy blasts and sword skills can pulverize Archdemon spirits and damage Military ones, the 3rd and 2nd strongest classes, capable of destroying cities and mountains. When dual-wielding, almost nobody can stop him, except some of the strongest elementalists and spirits, with equal speed or "binding" powers, like gravity, traps or chains.)

Speed: Superhuman movement speed up to Subsonic with added Divine Power, Hypersonic reactions and combat speed | Peak Human, Superhuman, Supersonic+ respectively | Same as 1st form | At least Subsonic, At least Subsonic+, likely Hypersonic+ respectively (He could move across an ever-moving terrain of rocks and fire. He was constantly adapting his own body movements to adapt to the terrain while running at high speed. Some sword techniques can make him go even faster.)

Lifting Strength: Superhuman (Exact level unknown, Kamito isn't a person to use pure strength in battle as he uses technique)

Striking Strength: Likely Large Building Class using "Destructive Impact" | Building Class | Likely City Block class | At least Small Town Class, likely higher

Durability: Unknown | At least Building level (Resisted a dragon's full-powered physical attacks and Leonora Lancaster in berserk mode.) | Likely Large Building level (Survived against the gravity magic of Leschkir, among the most killable magics.) | Higher, At least City Block level (Ignored pretty much anything Rubia threw at him, including an Absolute Zero spell)

Stamina: Above Superhuman (Can infuse his body with Divine Power for a long duration of time and is able to fight with life-threatening injuries), lower stamina if he dual wields. | Same | Same | Limitless Divine Power supply

Range: Extended Human Melee range with his swords(s), Several dozen meters with Energy Blasts and Projectiles

Standard Equipment: Vorpal Sword (Elemental Waffe form of the spirit Restia Ashdoll, capable of shooting black lightning) | Demon Slayer (Elemental Waffe form of the spirit Terminus Est; Kamito is able to dispel/absorb curses and cut through magic and beings with elemental mimicry. The sword can shapeshift into various blades, like daggers, longswords and shortswords. Est can harm the minds of weaker spirits and interfere with other blades causing them to be less effective) | Demon Slayer Zwei (Demon Slayer + Vorpal Sword, gains the powers of both swords | Both swords separate. In all forms, Kamito can summon regular swords and daggers.

Intelligence: He is a combat genius and a master of infiltration and assassination. He is known for his ability to trump foes he should be inferior to in specs, through sheer skill and analysis. He is also able to read his opponents' movements through their body language and the way their muscles move, allowing him to better anticipate his opponents' attacks. Due to his many years living at the secluded Instructional School, he isn't very book-smart.

Weaknesses: Doesn't like to kill. He is weak in spirit magic. Trouble against holy-attribute enemies. | Same and isn't as strong as when he was Ren Ashbell. Est can't use her full power due to being 'cut' from her real body in Astral Zero. Est's ability to absorb and pass curses to Kamito will eventually kill him. Trouble against dark-attribute enemies instead of holy. | Same | No attribute weakness, but his 'Demon King Mode' is an uncontrollable state where he becomes a berserker. Dual Wielding drains his stamina extremely quickly.

Notable Attacks/Techniques:

Assassination Skills

  • Meta Three-Dimensional Movement: A series of techniques that allows the user to run along almost any surface and any angle as if it were a flat and smooth surface, allowing Kamito to run on walls, ceilings, and even water.
    • Water Lily: Uses Divine Power to allow him to run on water. Can be used to fight underwater.
    • Aqua Elusion: Kamito syncs his body with the flow of water, completely eliminating his presence.
    • Demon Spider: Kamito uses Divine Power to stick to walls and ceilings, or pass through tight and narrow passages.
    • Thunderclap: A movement technique that grants him bursts of "god-like" speed.
    • Sword Break: In a situation where he lost his sword, Kamito can use this technique to cut without a sword.
    • Dual Snakes: Dual slashes with either blades or palms aiming at the opponent's neck.
  • Self-Suggestion: Kamito is able to perform special feats with his body by saying certain actions to subconsciously make his body perform them
    • Unknown Word: A self-suggestion that allows the user to choose when to wake up from sleep.
    • Solte: Saying this word allows the activation of a skill that enables the user to remove mental shackles through powerful self-suggestion, thereby allowing them to temporarily surpass the body's limits. Entering this state, the user will stop feeling fatigue and also become numb to pain to a certain extent. A strong backlash will however follow from using this skill.
    • «The Act of Mental Oblivion»: The user's mind becomes still like water allowing them to ignore outside light stimulus and lets them pretend to be asleep or dead.
  • Various Combat skills
    • Orochi: Launches countless slashes using short one-handed swords.
    • Destructive Impact: An assassination technique performed by wrapping a fist in divine power and releasing a shockwave to destroy defenses, pass through objects and knock opponents unconscious.
    • Snakes and Scorpions: An assassination technique where the user keeps a low stance and swiftly moves across the ground while attacking the opponent's feet.
    • Flying Snake: An assassination technique where the user unleashes and upward slash at godly speed.
    • Flashing Fang: An assassination technique where the user envelopes a bladed weapon with divine power and stabs directly at the throat.
    • Weapon Works: Spirit magic that allows him to create temporary swords.
    • Shadow Crossing: (Unknown Effect)
    • Sword Break: An unarmed technique that utilizes an elbow thrust at a person's hand, which results in stopping the enemy's downward strike in mid-motion forcefully. This technique was used against Leonora when she was fighting Kamito in the Blade Dance, right after losing Est temporarily.

Sword Techniques

  • Vorpal Blast: Launches a beam of jet-black lightning to attack the enemy, resulting in a large blast. Unusable in Base form.
  • Absolute Blade Arts: Strongest group of sword techniques in the series. Taught to Kamito by his master Greyworth Ciel Mais.
    • First Form, Purple Lightning: The fastest sword technique in terms of combat speed, delivering a single piercing thrust of extreme power and speed, which induces explosive power in a specific direction. The resulting force is capable of inflicting massive damage upon solid targets. This sword move has no effective counter.
      • Dual Wielding Form, Purple Lightning Revised: This technique was used by Kamito after regaining Restia. It is Purple Lightning performed by cross-intersecting the two swords.
    • Second Form, Meteor: A sword technique derived from Purple Lightning. It is the strongest single-strike sword attack. An aerial attack, a downwards swing at extreme speed powered by a large erupting release of Divine Power.
    • Third Form, Shadowmoon Waltz: Anti-army spinning sword technique which can defeat multiple enemies on all sides. Can also easily break weapons.
    • Fourth Form, Blazing Slash: A technique for countering fire users. Kamito dispels and absorbs flames directed at him into his blade, which he can then send back to attack his foes.
    • Sixth Form, Crushing Fang: An anti-weapon and anti-shield sword technique. Kamito slams the base of the sword's hilt with divine power, and the power resonates through the blade and creates a high frequency vibration that is able to shatter weapons and shields. The fastest sword technique in terms of movement speed, faster than the speed of sound (Transonic).
    • Seventh Form, Biting Dragon: An anti-air sword technique used by Kamito against Greyworth to counter her use of Meteor.
    • Mist Form, Water Reflection Mirror: An evasive technique using divine power to instantly create a lasting afterimage of the user and hide himself at the same time.
    • Flash Form, Death Butterfly Flash Dance: A counterattack sword technique unleashed at godlike speed, when targeted by an opposing sword attack.
    • Destructive Form, Bursting Blossom Spiral Blade Dance, *Insert Number (Max 21)*, Consecutive Strike: Massive combo of sword slashes at godly speeds. This attack was originally meant for dual-wielding but Kamito managed to adapt it so he can use it with one sword, but doing so severely strains the hand in use. It's powerful enough to destroy an Archdemon-class spirit (normally needing a small legion of Elementalists to confront).
      • Destructive Form, Bursting Blossom Spiral Blade Dance - *Insert Number (Max 21)* Consecutive Strikes - Lightning Flare: This technique combines the above attack and the "Vorpal Blast", effectively making it the strongest single technique seen by Kamito thus far. Powerful enough to one-shot Military-class spirits casually (stronger than Archdemon-class). The strongest technique seen by Kamito thus far.
    • Final Form, Last Strike: The ultimate Absolute Blade Art technique. It can only be used as a counter. In a matter of split-seconds, Kamito absorbs the opponent's attack and energy through the tip of his sword, and then counters in a single destructive strike. The stronger the incoming attack, the stronger the counter becomes. Capable of one-shot killing if the opponent isn't resistant enough.
      • Final Form, Dual Last Strike: Same as above but while dual-wielding, Kamito defeated Rubia's Muspelheim spirit with it.

Demon King Powers

  • Enhanced Divine Power: In this form, Kamito's mere presence is noted to be outright terrifying. Dragon spirits (which are among the strongest spirits) and other strong elementalists were terrified, quickly losing any and all will to fight. Kamito suffers no drawbacks from Est's high Divine Power consumption in this state.
  • Pain Ignorance: Due to being in a berserker-state, Kamito can move and attack while ignoring most wounds and pain.
  • Divine Empowerment: Although the specifics for now are largely unknown, since awakening as the Demon King, everytime Kamito has kissed another elementalist, a part of the power of the Darkness Elemental Lord he possesses deep inside him is transferred to them, drastically boosting their Divine Power immediately afterwards for multiple hours, increasing all their stats.
