When the world ends, Will's only hope of survival is collecting powerful spell cards and using them no matter the cost.
Will Carnell is an overworked, underpaid salaryman doing unpaid overtime when the System descends upon Earth, bringing with it a world of monsters and a series of Events that'll kill him or worse if he messes up. Anything is better than slaving away at a desk for twelve hours a day, six days a week, so honestly? It could be worse.
There's only one catch—he has a unique class, and there's only one way to grow stronger:
Collect cards. Build a deck. Fight. Survive.
