"Supreme God Anu?"

"Seven-Headed Evil Dragon Tathamet?"

These beings, who sounded extraordinary from their names alone, left the many big shots in Jujutsu High's conference room stunned three times over, each of them wearing an expression of agonized disbelief.

With their power and the efficiency of their subordinates, they quickly gathered information related to Diablo. They had not known until they looked—and once they did, they were thoroughly shocked!

Simply put, the setting of this "game" had once contained a creator-god-like being named Anu. In order to ascend into pure light, He expelled the darkness within Himself. That darkness became the seven-headed Evil Dragon Tathamet. The two fought for tens of millions of years before ultimately perishing together.

Anu's spine became the Crystal Arch, while Anu's pure will poured forth and became countless angels.

They were led by five archangels of the council: Wisdom, Fate, Valor, Justice, and Hope.

Evil Dragon Tathamet's corpse became the Burning Hells, while its seven heads became the three Prime Evils and four Demon Kings. Countless demons poured forth from its will to destroy all things.

The three Prime Evils were: Terror, Hatred, and Destruction;

The four Demon Kings were: Sin, Lies, Pain, and Torment.

Both sides inherited the wills of Anu and Tathamet and continued their fierce war. During the fighting, the angels and demons discovered Anu's eye, which possessed the power to remake the world. It was known as the Worldstone.

The many big shots found this deeply convincing.

It seemed that no matter the mythology, the Eye of God was always among the most supreme existences.

A war for the Worldstone erupted, and angels and demons battled for countless more years!

Yet the two sides were evenly matched. Moreover, whether archangels, Prime Evils, or Demon Kings, they were all incarnations of Anu
