The aggregate-body of the 72 demons.

After King Solomon’s death, the 72 demons that were sealed away inside his corpse awakened to their own ideology, swindled Solomon’s name (although, from their point of view, they are the true King of Magecraft Solomon) and embarked on a new venture to convert the entire mankind into energy.

To begin with, the 72 demons were “a system to efficiently promote proper reason” invented by the founder of (human) magecraft, Solomon.

Said system grieved and raged against the relationship between King Solomon and humans, becoming a curse that takes action to conquer “the imperfectness of humans” that King Solomon continued to ignore.

Its name is anthropic principle incineration formula, Goetia.

A magecraft with its own will that was devised in order to attain true wisdom, and is now attempting to reach the origin while making use of the entire human history.
