Jin Rou wanted to be a cultivator. A man powerful enough to defy the heavens. A master of martial arts. A lord of spiritual power. Unfortunately for him, he died, and now I’m stuck in his body. Arrogant Masters? Heavenly Tribulations? All that violence and bloodshed? Yeah, no thanks. I’m getting out of here. Farm life sounds pretty great. Tilling a field by hand is fun when you’ve got the strength of ten men—though maybe I shouldn’t have fed those Spirit Herbs to my pet rooster.

When Mira’s home is destroyed by gods, she makes two requests to the System that sends her to another world: to be sent to an isolated forest where she can avoid the violent path to godhood, and to gain magic that helps her live and thrive in the forest. She is granted both, though in the harshest way possible. The System strands her in a dangerous forest where half the plants are poisonous, the rivers teem with souls, and even the smallest beasts lay waste to experienced adventurers.

Orodan was an orphaned street rat who clawed his way to the county militia with hard work. When calamitous events unfold and draw him into events bigger than himself, Orodan's battle-loving disposition leads to a warrior's death. Then he wakes up again at the start of the Cataclysm. Then again. And again. In a world of skills, titles, and blessings, a smart time-looper would perhaps scheme, plan, amass equipment, and allies. But not Orodan.

Felix's life on Earth had become a series of dead-end jobs, ruined relationships, and rotating apartments smaller than most postage stamps. By all accounts, even his own, he was a coward.

When it comes to action and adventure, every hero needs a good sidekick. Holmes has Watson, Batman has Robin, and Daniel has . . . Orrin. More like brothers than friends, they always have each other's backs.

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.
