After saving one world from a Demon God and earning the trust and devotion of a perverted goddess, Sol is rewarded with all his powers intact and sent back home with the goddess accompanying him as his personal slave. 
 
That was supposed to be the end, the Demon God was supposed to be his last great trial. However, they are both summoned once again to an even more doomed world, almost immediately after returning to Sol's. 

This time around, Sol refuses his role as hero.

Unable to find rest, he turns his wrath to the pantheon of gods in a spiteful quest to become the strongest being in existence, followed by his slave who took his place as hero. 
Battles await, secrets of old begin to scurry into the light when the world as he knows it begins expanding beyond the visible horizons of reality and deep into the fringes of eternal darkness.

Terrible consequences lay beyond the borders of the known.

The World's most Overpowered Side-Character

"Are you okay, Sovereign Vestic?" Xie asked, looking at Sol strangely while he stared off into space, twitching and trembling.

Sol's hair; a bright gold, began to slowly turn into crimson, his forehead started bleeding when two smooth black horns began protruding from his flesh, curving upwards while Xie watched in fascination as the previously calm man underwent what was clearly demonification.

"I am fine, Xie... but there is an entire dimension of Fae and a Grand Fae as powerful as a Heavenly Ancestor that need to be slaughtered before we hurry back to my home, are you confident in your ability to Kill the Grand Fae?" Sol asked, glancing over his shoulder at his new subordinate.

"Of course, it took several Heavenly Ancestors to subdue me before, a single master is no threat."

"Good," Sol nodded.

Whatever The Cost.
