Zack “Kazz” Foreman once was a human from the earth when humans went through a dramatic change because of an event. This forced them to evolve into energy-based beings but was sucked into another dimension.

Forced to start living out lives on random worlds in a fractured dimension, Humanity is placed on the path of complete extinction.

This is controlled by a demon king at a place called The Center of Everything.

The Demons try to force Humanity's mark from every reality, so there are only demons, but the Demon King feeds from anger and pain. A constant tournament going at the center of everything to feed his hunger.

Kazz made it to that point once, but was tricked, refused entry to the tournament because he had offed a place one of the gods of the worlds.

Refusing to give up, Kazz goes back to the beginning to start again. To do this, Kazz must give up all of his memories to choke the flow of demons born fully grown from a pool of recycled souls.

This journey starts after he lives a solitary life trying to get stronger but not knowing why. The world Kazz is on is like our earth, but it was only a mimic of the earth we know.

Caught using steroids and about to give up and join the army, Kazz stumbles onto a cave in the ground. He is transported to a world filled with demons and monsters, and a human god named Hero is speaking in his head.

Hero, a person Kazz knew but was not friends with, followed him to help but was lost from him. Upon meeting Kazz, Hero offers him the Hero System to help him advance in this new world.

Kazz refuses after trying to get to the top and failing to use the easy route. This starts a series of frustrating events for both Heroes, but they learn to work as a team over time.

Kazz will meet misbegotten monster girls and demons that he agrees to take care of in this world, using the Ranching System. It only gives bonuses to the girls and skills to help raise them, but he will also learn to control the Elements with Shamanic abilities.

Shoved into the backseat of his father's car right after graduation, Riley Hale ended up marching toward a company building with a bagged lunch and a pen.Still in his toga, the fresh graduate never thought he’d land in the office of the continent’s top lizard, err, dragon, as his aide.And that would’ve driven any person wishing for a corporate career to tears. After all, who wouldn’t want to serve the fastest ticket up the corporate ladder: Kael Dravaryn, the infamously elegant, unhinged, and extremely overpowered Dragon Lord of the continent?Well, that would be Riley.The same Riley who didn’t expect to spend his days dodging fireballs, dressing his boss in robes more complicated than dark magic, and serving as a literal target during morning sparring.Now trapped in a job he never truly agreed to, the hardworking aide decided to hold out until it was time for his glorious resignation. But leaving a dragon’s clutches could never be easy, especially one with elemental mastery and a finger worth a private army.Yet, as Riley, who longs to quit, attempts to navigate ancient politics, wyvern threats, and other accidents (many of which are definitely not his fault), he might just hallucinate himself into seeing something beneath his boss’s arrogance and molten glares.Maybe he’d actually care if Riley got turned to ash.

Short, rich, and handsome, Lin Feiran was always the center of attention. But after transferring schools in his second year of high school, he discovered that his limelight was snatched by his Adonis classmate, Gu Kaifeng.
