His birth (manifestation) happened in the distant past.
Born as an absolute being, he had sway over other beings with his Charisma.
The embodiment of Pride.
If he had grown like that, he could have been a being who would be called the King of the Underworld.
It was somewhat of an accident for a being such as he to be brought into the over world, but this was an event that will end up changing his fate significantly.
After arriving, he surveyed his surroundings.
He understood immediately, that he had been summoned.
The man who looked like the magician who summoned him was annoyingly spewing prideful words.
His wish was to destroy the opposing country which his side was warring against.
That was a simple matter.
Using the wide range destruction magic ――Death Streak―― without hesitation, he spread death easily.
Millions perished and cities of death were created. He felt nothing from what has been done.
But, attaining massive quantities of souls, he noticed he has ascended to a True Demon Lord.
It seemed, just reaping ten thousand human souls, was enough to reach ascension.
Then, what would happen if I collected even more souls? He was curious.
Also, he wanted to “repay” the person, who decided to give him such a “chore”.
He summoned two retainers ――Arc Demons―― and gave them orders.
Swiftly erase this country from the face of this world.
He was currently in a good mood, having ascended.
The point was that he had destroyed the residents of the country, that the magician who summoned him and gave him such a “chore” resided in, with no pain or suffering. That alone, proved how much of a good mood he was in.
Also, the demons he summoned had the honor of being granted physical bodies.
Thus, a once flourishing, but having been divided, great country, that wielded ancient super technologies, met it’s demise.
Such had happened thousands of years ago.
Although a country ended up destroyed as his idea of an experiment and “payback”, he collected even more souls, but there weren’t any more changes.
Which led him to understand, he cannot be strengthened any further.
This marked the start of boring days to come, but Guy didn’t mind.
He roamed about everywhere, focused on enjoying the world for what it is.
His life wasted on only battles and refining his Soul in the underworld, now seemed bleak in comparison to the stimulating outside world.
Having fistfights with gigantic demon beasts, decimating self proclaimed monster kings with his magic.
To the native humans, he was viewed and known as both as a God and a Devil at the same time, it was such a period.
And then, they met.
The one who created the world, the ultimate existence.
“Stellar Dragon King” Veldanava. He who had created the world they live in.
