Nathaniel's bus ride was supposed to be just another boring commute. Wrong. Now, he, 23 fellow passengers, and a corgi named Biscuit, are stuck in a "Hell Difficulty" Tutorial, battling monsters and leveling up to survive. Easy difficulty, anyone can handle.

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.

For Daniel, however, it's closer to a nightmare.

Then things take a turn for the truly weird when a terrible accident catapults the pair into a world totally unlike their own, in which the rules of a role-playing game hold sway.

Who would have guessed that? When these cruel gods shuffled Earth like a deck of cards, nothing was in the same place anymore. Monsters, dungeons, and magical items appear scattered across the globe. And suddenly, everyone has access to a new, strange magical card system that gives them magical powers.

Jay Luckrun has many interests: street dancing, anime, action movies, comedy, and dashing across rooftops to the point where his bullies nicknamed him Rooftop Weirdo.
