Anos Voldigoad

Anos Voldigoad (アノス・ヴォルディゴード, Anosu Vorudigōdo) is the first and most powerful Demon King, and is the main protagonist of the series.

Appearance
Anos is the founding demon with black hair and red eyes (Demon Eyes). He's been described as being a pretty boy and is usually seen wearing his school uniform which consists of a black shirt along with a white jacket and trousers along with a red belt. As his Anosh alias he's seen wearing a demon royalty uniform which consist of a black shirt, jet black jacket and trousers with a heptagram which is only given to the most outstanding of students.

After he officially becomes the Demon King, he is usually seen wearing the same Demon King outfit he wore 2,000 years ago.

Personality
Anos is the reincarnation of the man who was feared as the Demon King of Tyranny 2,000 years ago. He is resolute, stalwart, and invincible. His absolute power instils a veritable self-confidence that is only surpassed by his ego. Because of his overwhelming prowess, Anos possesses an easy going attitude and an unrivalled sense of perseverance when facing any challenge that may come his way.

Despite his title as the Demon King, Anos has a definitive moral compass and generally has a kind and caring outlook. He takes a great interest in the well-being of not only his family, but also his subordinates and followers, and is quick to reward them for their loyalty. He is willing to go through great lengths to assist in their development, in order for them to reach their full potential. Other people may see him as cruel, but his personal creed is not to kill people needlessly. Even if he would never admit it, Anos is very protective of his fellow subordinates and followers.

While Anos is not inherently evil, his chaotic and sometimes ruthless methods when dealing with his enemies, earned him his title. While he originally never proclaimed himself as the Demon King, he has openly embraced it as the rest of the world views him as such. Those who oppose him, fear his power, and are threatened by the mere fact that a single man possesses such power.

The legends of just his gaze striking fear into those who appear before him are not just a rumour either. Just using his demonic eyes to control others' actions is enough for some to go mentally insane.

History
2,000 years ago, in his previous life, Anos was an orphan. Humans killed his mother while she was pregnant with him and he was born from her corpse. He said that it was something he could never forget.

As the war between humans and demons raged on, Anos eventually grew tired of the constant fighting and decided that the only way peace could be achieved was by building walls between the four races, hoping they'd forget their grudge after a thousand years or so. Thus he formed an agreement with the Hero Kanon, Great Spirit Reno, and the God of Creation Militia and sacrificed himself to supply enough magic for the cause, saying that he would reincarnate after 2,000 years.

The unborn child which Anos would reincarnate into, was close to death while still inside his mother's womb. Because the doctors couldn't do anything, even with magic, Izabella prayed everyday for her child to be born. It didn't matter to her which divine or demonic being answered, so long as they'd help her child. While she was sleeping, the baby's heart stopped inside of her. Izabella prayers were finally answered when the child's heart started beating again. Little by little, the unborn child regained his strength and grew as Anos' root choose the unborn child to reincarnate in, thus returning life to it. He believes that it was because of his mother's sheer force of will that he was drawn to the baby.

Abilities

 * Immense Magic Power: As the Founder, Anos possesses an extraordinary amount of magic power which surpasses all other beings on the planet. His power is so monumental, that it cannot be measured by normal means. Anos has mastered almost all types of magic, but he admits that he loses to Kanon in root magic. He also mentions that the only category he is completely unrivalled in is destruction magic, and that Misha could potentially surpass him in creation magic.
 * Immense Physical Strength: Anos has displayed an insane level of physical strength whenever anti-magic was concerned. As shown during the inter-team battle exam, where he lifted up Sasha's entire castle with a single hand, and spun it around his index finger. He also displayed this strength when he opened up the ginormous gates that guarded his spectre hidden beneath the castle. It's been stated that Anos can destroy a universe with only his fists.
 * Root Intimidation: Magic power comes from the source itself, so if it becomes afraid of the opponent, it causes the magic to go out of control and explode. As the Demon King of Tyranny, Anos' source is far superior than others, thus it is feared by many.
 * Demon King Origin Magic Immunity: Origin Magic is a type of magic that borrows the power from an ancient being to cast. Being the Demon King himself, any spell cast that calls for his own power is rendered useless against him.
 * Spell Theory: Anos possess an extremely high level of magic knowledge. Easily creating many powerful spells such as teleportation and the Demon King Army. He also masterfully enhances spells previously thought to be perfect and completed the fusion spell which one of the Elder Demon Emperors has spent thousands of years developing. Even the evil royals who spent over 2,000 years to study magic couldn't beat him.
 * Blood Corrosion: Anos' blood corrodes the world.
 * Source of Perdition: Descending from the Voldigoad bloodline, as well as being a Lion of Destruction, Anos possesses a unique source. As stated by Ron Cruz, the source consists of endless destruction and is as bad as or even worse than living in hell. The closer Anos' source comes to annihilation, the stronger he gets.

Magic

 * Demon Eyes of Destruction: Demon eyes which allows Anos to disintegrate whatever he looks at including his opponents' mind and magic itself. It also allows him to put anyone he looks at to sleep, but this is merely a by-product of it. Additionally, Anos's demon eyes always work on his favor and seem to act on their own to an extent, as well as being able to affect and "destroy" even abstract powers.
 * Demon Eyes of Chaotic Destruction: The original demonic eyes of Anos before he suppressed and replaced them with the much weaker Demon Eyes of Destruction. The essence of these eyes is destruction, and it possesses unfathomable power that destroys even the indestructible. Merely the opening of these eyes will cause the entire world to collapse. If there is a contradiction between the Demon Eyes of Chaotic Destruction and Order, the Demon Eyes of Chaotic Destructing will win unilaterally. Due to how chaotic and destructive these eyes were, Anos suppressed his power to the limit and never used them, eventually obtaining the much more reasonable Demon Eyes of Destruction. Later on, Anos is able to use the Demon Eyes of Destruction while still having access to the Demon Eyes of Chaotic Destruction.
 * Hell Flame Annihilation Mortar : Said to be the highest-ranking of attack fire magic within the demon race's magic system, a powerful miniature jet-black sun which can be fired off at the enemy like a comet. As is the case with all forms of magic, the more powerful the user, the more powerful the spell becomes. In the Mythical Age, one caster could use multiple , but in the Magical Age, 20 people could only reach a 20% success rate.
 * Demon Black Thunder Emperor : Origin magic that borrows power from the Demon King of Tyranny. It is a typhoon of powerful black lightning that rains destruction onto enemies.
 * Demon Black Thunder Fang :  is used to activate the technique of , causing the black lightning to mercilessly cling and tear into the enemy's roots until they are destroyed for good.
 * Root Kill : Anos stains his fingertips in dense black magic particles and impales with his spear hand towards the enemy, this directly attacks the source, possibly destroying it permanently if the attack is successful.
 * Deep Root Kill: By deepening the original , this more powerful variant was formed. It possesses the same properties as the original , with the only difference being that it is many times more powerful than the original.
 * Four Worlds Wall : The wall that divided the world into four 2,000 years ago. It was made by combining the magic power of the God of Creation, the Great Spirit, the Hero, and the Demon King. It rejects everything and destroys them. However, Melheis had taken it before it disappeared 1,000 years ago. Anos can clad any part of his body in the same wall that separated the world, to act as either a protective barrier or to strengthen his attacks.
 * Hell Flame Binding Magic Circle : A magical technique that summons chains of hell flame to constrict the enemy's movements and finish them off.
 * Demon King Castle Summon : This great magic that moves the Demon King Castle Delsgade, capable of emitting enormous magic power because it was originally a fixed magic tool, which was certainly impossible 2,000 years ago. However, origin magic is older, and by borrowing from an entity with greater magical power, it is possible to produce extraordinary results. If we borrowed power from Delsgade 2,000 years ago, it is not impossible to summon Delsgade of this era, which has a close relationship with it. Anos can only use  within the vicinity of his Demon King's Castle, however, he can summon his castle anytime he wishes in exchange for using up a lot of his magic power.
 * Everything  : The magic that allows the user to ignore physical distances, grasping, and taking control of everything. Anos used this magic to move the moon to make an eclipse happen nine days earlier than it should have.
 * Wavy Body Covered Reveal : Anos' magic power fluctuates between possibility, so too, does his root and his body, when Anos uses this ability he encompasses all possibilities, the possibility that he attacks, or the possibility that he doesn't, all at once. Therefore, when using this ability, Anos could be standing still yet attacking at the same time.
 * Demon Curse Necrosis Destruction <Deguzegdo>: A curse resembling a black snake that appears on the body and causes the opponent's magical power to run amok leading to their death.
 * Demon Rock Falling Star Bullet <Gia Greas>: Huge jet black stones that pour out from a huge magic circle within the sky.
 * Water Prison Destruction Waterfall <Rio Edram>: A huge magic formation on the land that spews out a powerful jet black waterfall upwards.
 * <Superimpose>: Anos can superimpose some of his attacks on top of each other to increase its power output.
 * Jiao Death Annihilation Brilliant Fire <Avia Stan Ziara>: A fire magic developed by Mage King Bomiras that is an attribute higher than the Jio Graze. By forming a three-dimensional magic circle via multiple Jio Graze's, intense heat rays can be gathered on any part of the body resulting in an immensely powerful jet-black flame.
 * Shackles And Collars <Nedonerias>: Anos summons a collar around the neck of a defeated enemy, which can induce them into a nightmare they will never wake up from unless either they fulfil certain conditions, or Anos releases them of his own volition.
 * Palm Demon Ash Purple Annihilation Thunderfire Electric Field <Laviers Gilg Gaveriizd>: A magic spell that Anos ends up inheriting from his original father. Said to be a doomsday magic with power that far outstrips that of Black Thunder Emperor <Jirasd>, it is an unfinished deep magic that rains down immensely powerful purple lightning from the heavens to simply annihilate anything in its way.
 * Grasping Magic Hand <Rayon>:A deep magic Anos acquires during the events of the Silver Sea. Anos coats his hands in layers of special magic that can be used to "catch" magic directed towards him by an enemy, or magic he himself produces. He can then compound said magic multiple times back and forth between his hands to make it many times more powerful before shooting it back at an enemy.
 * Supreme Flame Magic Heavy Cannon <Dogda Azbedara>: Highly explosive flame magic that trails towards the enemy in the form of a blue star. As a deep magic, its power is far beyond <Jio Graze>, to the point that it's not even comparable.
 * Extreme Hell Destruction Ash Demon Mortar <Egil Grone Angdroa>: Destruction magic, the magic that Anos is the best at. Burn what is supposed to burn, destroy what is supposed to perish, and turn the whole world into ashes. A "fire" magic that exceeds <Hell Flame Annihilation Mortar>. The reason it is not positioned as the highest class of magic in the fire attribute is that only Anos can use it, and despite being in the form of a flame, it is totally another thing. When this world-destroying magic is cast, massive black flames dance across the entire world, burning anything and everything in existence to ashes.
 * Nirvana Seven Steps Conquest <Gili Eliam Naviem>: The second of Anos' world-destroying magic. There are seven steps, with each step further raising his bottomless magic power. With every coming of Anos' steps, the entire world begins to shake more and more violently. If the seventh step is unleashed, the already fragile world will be completely destroyed.

Weapons and Equipment
Principle Destroying Sword <Venuzdonoa >: This is Anos' main weapon, it is the demonic sword of the founding ancestor that annihilates everything, destroy all creation, laws and the universe. No matter how strong, eternal or infinite <Venuzdonoa> will destroy them all.

<Venuzdonoa> doesn’t follow reason nor anything number related or things related to distance whether it be magical or conventional, as anything that can be reasoned returns to nothing before it, hence it's useless to think about what it can or can't do. The only principle that <Venuzdonoa> allows to exist is the destruction of Anos' enemies.

It can only be used in the vicinity of the Demon King Castle Delsgade, but Anos can move the castle by using <Delsgade>.

The Sword of the Almighty <Levine Girma>: A divine sword created by Arcana. If one were to pull it out from its sheath, their root from the present, past, and future would instantly be permanently erased from existence. Anos is able to use this sword thanks to his <Veneziara>. The true power of this weapon is that it can cut through anything no matter how indestructible it may be.

Two-Rites Sword: A jet-black magic sword formed by connecting to the body of the Two-Rites Tyrant with Demon King Army <Gyze>, and mutating the body with Body Mutation <Athens>. Due to the connection made through <Gyze>, the Two-Rites Sword acts as a second vessel to Anos, being able to contain his source of perdition. A normal vessel would immediately perish, but because the body of the Two-Rites Tyrant was extraordinarily strong, it could contain Anos' source of perdition. Anos stores a large amount of his magic power which originates from his source of perdition into this sword. As a side effect from being formed from the body of the Two-Rites Tyrant, the Two-Rites Sword gained his unique ability, the <Niritsu Kageto Dougdara>. By attacking the shadow of an enemy, immense damage is done to their real body. The combination of storing a large amount of Anos' magic power as well as possessing the <Niritsu Kageto Dougdara> makes this weapon incredibly powerful. It is considered an extremely deep magic, even by the standards of the Silver Sea.

Diamond Iron Sword: A handcrafted sword forged and gifted to Anos by his father, Gusta. Anos used it throughout the Magic Sword Tournament. While the sword does not compare to the magical power of many of his other personal items, Anos treasures it the most, as it was suffused with his father's love.

God Seat Heaven Gate Summon Selection <Guala Nate Forteos>: An allied beads that can summon selected god for the god seat. Anos uses this to summon Arcana.

Anos is said to possess various other weapons.

Trivia

 * His favourite food is mushroom gratin. After reincarnation, his mom makes it for him all the time.
 * In Episode 4 and Episode 13, an alternative version of the opening theme was sung by Anos Voldigoad's voice actor, Tatsuhisa Suzuki.
 * Like Atsushi Nakajima from Bungo Stray Dogs, Anos Voldigoad belt acts like a tail.
 * Anos deeply treasures the love and support that he receives from his parents, Gusta and Izabella, as his past incarnation was orphaned, and grew up without any family at all.
 * While both of Anos' parents are human, one of his ancestors was a demon, causing the pure-bloods to still refer to him as a hybrid or mixed-blooded demon.
 * Many royals and pure-bloods are unable to see past the fact that Anos was "reborn" as a hybrid, and conceitedly refuse acknowledge that the Demon King of Tyranny would choose to reincarnate from anything other than pure-blooded parents. Even many pure-bloods who possess demonic eyes, would refuse to analyze his blood, due to this misconception.
 * He is said to be so powerful that even divine magic is kept at bay.
 * It was implied that Anos reached the bottom of the abyss and he described it as "shallow waters".
 * Being half-asleep, he nearly destroyed Dilhaide using <Jio Graze> because he was fighting Kanon in his dream. Surprisingly though, no one died because he still had that much control while half-sleep.
 * As a result of using Reincarnation <Silica>, he could only use one tenth of his immense magic power. He had gained his original power once the source was fully awakened.
