72 demon gods, assembled as one.
After King Solomon's death, the 72 demons who were sealed within his corpse awoke to a unique ideology, took Solomon's name for themselves, and set about on their task to convert the entire human race to energy. From their perspective, they became the true Mage King Solomon.
The 72 demon gods were originally a system created by the human Solomon, the founder of magecraft, to "efficiently advance reason in the correct direction."
They came to resent the relationship between King Solomon and humans, and became a curse that attempted to overcome the "human imperfection" that Solomon had ignored for so long.
Its name is Goetia, the system for the Incineration of Humanity.
A sentient magecraft woven to reach true wisdom, and to use all of human history to reach the beginning of all.
BOND 2
A Beast who calls himself the King of Demon Gods.
He possesses a sense of omnipotence which commands all the laws of the earth and the heavens, and holds a hatred so great it as if he despises all of mankind. He wears ten rings, one on each of his fingers, but the left middle ring is a replica.
As King Solomon is his base, he had a terrifying but logical personality.
However, since he is an amalgamation of the 72 Demon Gods, he also has 72 personalities and natures. He is both one and a colony, and so when he talks with others, the Demon God most similar to that person appears on the surface. This is why Goetia's disposition has been described as a mirror.
He is the omnipotent being that even Solomon could not become. He was more than capable of becoming a king that could rule over man. But because of his omnipotence, he could not understand human nature, and because he was immortal he was not able to reach an answer. Thus, he was never able to become the "king of man."
BOND 3
Summoning: EX
Magecraft where spirits from the past or form the future are evoked.
After King Solomon's death, the concepts called the 72 Demon Gods which were left behind dwelled inside King Solomon's corpse. After a long time, something wearing King Solomon's skin was born.
Though this skill cannot bee used to summon normal familiars or Heroic Spirits, he is able to summon any of the 72 demons at will. It is easier to understand him as a generator that projects the "fictional demons gods" that had nested inside King Solomon's inner world to the outsider world.
Revelation: -
A skill that makes one capable of hearing the voice of Heaven and take the most appropriate action accordingly.
As this is a skill within the soul, Goetia, who nests inside King Solomon's corpse, cannot use it.
Clairvoyance: EX
As clairvoyance is a skill retained by the body, Goetia is able to use it.
BOND 4
Goetia's goal is to reach the apex...
To become the only existence on this planet.
Solomon knew of man's ugliness and how they were beyond salvation, but he accepted death rather than correct it.
But the Demon Gods did not agree with him. They decided that there was no value in man and the future, and feared annihilation.
They not only hated the idea of their own annihilation, but also of the annihilation of everything.
BOND 5
And thus, Goetia resumed activity by nesting within King Solomon's corpse, but they quickly ran into a major dilemma.
They had declared that man was worthless, but as Demon Gods, they could not exist without serving man. They were humiliated to find that despite being a higher-dimensional life form, they had to place themselves below man, the universe's most wholly obsolete creatures.
This contradiction and torment did not sit well with Goetia, who thus embarked on a self-revolution.
Their aim: Resetting the objective of serving mankind, to have absolute proof that they are the greatest being on the planet, to reach the apex that Solomon could never reach.
In other words, they began their great quest to achieve godhood.
Clear "Return"
And thus began Goetia's plot, the thing which called itself Solomon, the King of Mages. He created the Holy Grails as Singularities to destroy the course of history, and the mages he designated as his descendants (who could transform into Demon Gods at Goetia's command) scattered throughout history to create seven detonation points.
This was the cause of the collapse of the Foundation of Humanity in each era.
Once the plot was realized, human history beyond the year 2018 vanished.
It was only after these achievements that his Class was determined.
"Grand Caster" was only a false rank.
He was created by man. A great catastrophe that effectively abused human history.
His name is Beast I.
He is one of the Seven Evils of Humanity, and the Beast that possesses the principle of "pity."
The arrogance of man taking pity on another and becoming disappointed.
Such is the bestial nature of Goetia.
