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 and has black hair and red eyes (Demon Eyes). He 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.

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 reincarnated man who was feared as the Demon King of Tyranny 2,000 years ago. He is resolute, stalwart, and invincible. His absolute power instills a veritable self-confidence that is only surpassed by his ego. Because of his overwhelming prowess, Anos possesses an easygoing attitude and an unrivaled 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. Anos 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 rumor 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.

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 unrivaled in is destruction magic, and that Misha could potentially surpass him in creation magic.
 * Root Intimidation: Magic power comes from the root 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' root 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 Erosion: Anos' blood erodes the world.

Magic
See: Magic
 * Demon Eyes of Destruction
 * Hell Flame Annihilation Mortar : Said to be the highest-ranking of attack fire magic within the demons magic system, a powerful miniature jet-black sun which can be fired off at the enemylike 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. Anos is said to have burned down Dilhaide with this spell while half-asleep.
 * Black Root Source Death : Anos stains his fingertips in dense black magic particles and impales his spear hand towards his enemy, this directly attacks the root, possibly destroying it permanently if the attack is successful.
 * Demon Black Storm Emperor : Black lightning gathers on the user's hand, increasing in size and power until it becomes a destructive typhoon.
 * 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 has taken it before it disappears 1,000 years ago. Anos can clad any part of his body in the same wall that separated the Infernal Realm, the Human Realm, Spirit Realm, and God Realm for 1,000 years. This can act as either a protective barrier to strengthen his attacks.
 * Hell Flame Binding Magic Circle : Origin magic which builds up a magical technique to attack the enemy while simultaneously restricting the movements and magic of the enemy.
 * Demon Rock Crusade : Anos can summon countless meteors clad in black magic particles to rain down on any enemies.
 * Demon King Castle Summon : This great magic that moves the Demon King Castle Delzogade, 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 Delzogade 2,000 years ago, it is not impossible to summon Delzogade of this era, which has a close relationship with it. Anos can only use  within 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.
 * : Anos can superimpose some of his attacks on top of each other to increase its power output.
 * Wavy Body Covered Reveal : Anos's 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.
 * Jiao Death Annihilation Brilliant Fire : Anos clads his hand in the powerful flame, often used to superimpose on top of other abilities.
 * Shackles And Collars : 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 fulfill certain conditions, or Anos releases them of his own volition.
 * Palm Demon Ash Purple Annihilation Thunderfire Electric Field : Magic spell Anos ends up "inheriting" from his original father. Said to be a doomsday magic with power that far outstrips that of Black Thunder Emperor Girasd, immensely powerful purple lightning rains down from the heavens to simply annihilate anything in its way.
 * Grasping Magic Hand : 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.
 * Extreme Hell Destruction Ash Demon Mortar : 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 Conqueror <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
See: Equipment

Principle Destroying Sword <Venuzdonoa>: This is Anos's main weapon, it is the sword of the founder which can destroy all creation 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's enemies.

It can only be used inside the Demon King Castle Delzogade, but Anos can move the castle by using <Delzogade>.

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 that Anos acquires during the events of the "Silver Sea". By converting the body of the Two Rites Pretender Ronculus who's vessel could contain enormous magical power into Anos' own personal magic, this sword then came into existence. The Two Rites Sword contains the power of an Extreme Hell Destruction Ash Demon Mortar <Egil Grone Angdroa> that Anos casted within it, as it has the capability to take in a large part of Anos' Root of Destruction. A very powerful weapon overall, it has an ability to directly attack one's shadow, making the user of the weapon invincible during that time frame as well as doing immense damage to the real body of the one who's shadow was attacked.

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.

Heaven Gate God Seat Selection Summon <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

 * 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.
 * Anos almost died, while still in his mother's womb. He believes that his root choose to reincarnate him through the unborn child, ultimately saving it, due to her prayers and her promise to always love and raise the child, no matter what the child turns out to be.
 * 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".
