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

"Dimensional Magic...?" Yu muttered, watching the two skills create a matter eating explosion at the core of which Sol had an array around himself feeding the explosion with his mana in order to prevent his body from sustaining harm.

"Crazy..." Dina rubbed her forehead in disbelief. "She's actually crazy."

"If that were anyone else, such a technique would be the end of them," Ikaris admitted. "It is not overly powerful, not in comparison to what we have done in the past, but the nature of it is destroying the very fabric of existence which it makes contact with... what a shocking skill."

"Form Seven," Arla leaned forward creating another Gamma Sword. "God-Killer... Awaken."

"By the Pantheon," Dr'ul stood completely, holding the system window before her and pulling it closer to her face. "This is coming from a demi-god?"

"When did she surpass everyone like this?" Renia asked. "This mana she possesses-"

The Gloves Come Off.
