With one touch of the stone, Tyron receives his Class and his life changes forever. In an instant his bright and promising future as the scion of two powerful Slayers is torn apart and he must make a decision.

I guess trying to catch the bus with your laces undone isn’t such a smart decision after all… One fatal collision later, and I’m facing my judgment. As it turns out, I’ve been a lazy sob, and my short, uneventful life of playing games and getting up late wasn’t worth much. And so I don’t qualify to move on to the afterlife. I try to argue to the goddess in front of me that I do have skills, that it was hard work playing those simulation and management games. But she will not concede. In the end, I manage to get the benefit of the doubt, and a wager is made.

Multiverse Z came knocking, snatching all the humans from Earth to integrate with their game-like realms of magic. No warning. No tutorial. It's an instant transition where eighteen-year-old Joey Eclipse is thrust from his relaxing night playing video games to a stone room with two doors. There's nobody but him. The system messages asking some cryptic questions: [Adventurer or Commoner?] [Greatness or Steadiness?] And more. Joey made his choices, choosing the path of a Great Adventurer, a limited and special category. A unique profile is designed for him.

Humans have been pushed to the brink of extinction by an ever-evolving demonic threat. Portals are opening faster than ever, Towers are bursting into the skies, and Dungeons are being mined below the last safe havens of society. The demons are winning. Quest Academy stands defiantly against them as a place to train the next generation of Heroes. The Guild Association is holding the line but is in dire need of new blood and the powerful abilities they could bring to the battlefront. To be the saviors that humanity needs, they need to surpass the limits of those that came before them.

The system came. The apocalypse ended. Now new worlds have merged with Earth. For Bain Lee, it means leveling his Ocularist class beyond its previous limits. With this strange class and the ability to see into the inner workings of the system, he may find the magic skills needed to earn his redemption. Not only that, but he might discover the secret behind the system itself.

Leading astrophysicist Liam Jackson is participating in a scientist exchange program in Germany when a curveball of universal proportions is thrown at him.

The fundamental forces of the universe are behaving differently, and Liam needs to understand them if he wants to survive.

When Manchester Yards donates a new training vessel to the Merchant Officer Academy at Port Newmar, Alys Giggone recalls the Chernyakova.

They have to sort out the crews of two ships, figure out what lessons they need to teach, and who will get those lessons. Once they agree, the trouble starts.

Trevor Anderson is just another normal, overworked retail worker. All he wants is his promised promotion, a chance to use some of his vacation days without feeling guilty about it, and time for his hobbies. While waiting patiently for his life to improve, a workplace accident changes everything for Trevor, including the world he resides in. After he bungles his way through a summoner’s questionnaire and gains the Power of an extradimensional inventory, he lands in the peaceful town of Tosa.

Fight, survive, adapt, and rely only on yourself. That is Derek’s creed and what's got him through the System Integration on Earth. Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet. War has raged ever since. None of this mattered much to Derek, aside from making living a little more perilous.
