In the Prime Kingdoms, the system dominates everything. It dictates one’s strength, skills, and power. It spawns dungeons and guides the actions of their monsters. But every system has its limits, and it’s about to push four oddball adventurers to theirs.

Elise was always made fun of for her big ears and buck teeth. She tried her best to overcome the mockery, only to work herself to death and wake up as... a big-eared, buck-toothed rabbit. Now, with nothing but an almost worthless System Assistant to help her, she needs to survive in a world full of magic and monsters. On top of all that, for some reason she's been given the ominous [Mark of Fate] skill. She has no idea what it does, but things keep happening to her, most of them unpleasant.

After being killed by a high-velocity tree-hug, Arlo is transported to a new world where those brave and talented enough to conquer ancient Delves are rewarded with incredible power and abilities. Unfortunately for Arlo, there is no tutorial. He is immediately forced to tackle a Delve set to the highest difficulty with a party of adventurers who are not only strangers to him, but strangers to each other as well.

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.

As a monster, Shrubley is forbidden from joining the adventurers guild. In a world where essence artists rank up in power and most monsters are feral beasts, Shrubley is among the weakest of creatures and is treated as an outcast. With curiosity essence bound to his spirit, Shrubley might be weak, but he's intelligent and determined. Against all the odds, he discovers a loophole from the Druid that gave him life—but there's a deadly catch. For a chance of ever being accepted as a true adventurer, he must challenge an otherworldly realm threatening to consume everything.

A young man lives among the trees of a primeval forest, raised by a wizened old sage and friend to the faeries and spirits of his home. He bears only half a name—Lien, an ancient word meaning "blade" or "edge"—and no knowledge of his heritage. As he grows, so too does his need for independence and answers. Thus, he begins his adventure, seeking a shattered sword and the truth behind the mysterious mark on his right hand.

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.

Somebody once told a joke. A man ran in place all his life. He worked a job he didn't love for people he couldn't stand. But at the end of the day, the number in his bank account went up. That man got a second chance at life. He woke up in another world, one full of adventures and romances and monsters and gods. And floating above his head, he saw the number "1". So what did he say? "Gosh, I better make the number go up." Not today. Not for this old soul. Reborn as a beast of battle meant to live a short life and die screaming, Garek refuses.

After Lucas dies during a freak explosion, divine intervention sees him brought back to life with the power to control a new dungeon. There are just a couple of issues: his old body is bound to his dungeon, and the craziness of what he thought was his final act is only getting weirder. When he sees newbie adventurers entering his dungeon, though, he decides to help them survive and complete their quests. After all, adventuring is a process, and someone needs to guide the rookies.

Syl was given a choice by Gramps when they died. Reincarnate as a regular person or embark on a daring experiment. Driven by a desire to honor Gramps and a sense of adventure, Syl chose the latter... only to awaken as a lowly slime. A farmed slime. The life of a farmed slime was cruel. Syl was constantly at the mercy of humans, a slime whose only purpose was to eat and recycle garbage. The threat of lethal core-destroying knives wielded by innocent children was a constant shadow. This was not the life Syl had envisioned. So, they made a daring escape to the wilderness!

Earth was chosen for Integration, but Ethan Hill knows from the second his Trial begins that the Integration is a lie. The beings giving Earth the 'honor' of access to their System Interface want something from Earth—he just doesn't know what. Now he's trapped on an alien planet and lost in a time loop, fighting for strength and for his own humanity. One thing's for sure: He'll die as many times as it takes to tear it all down.

The decision to start a new life is never an easy one, but for Joe the transition was far from figurative. Becoming a permanent addition to a game world, it doesn't take long to learn that people with his abilities are actively hunted. In fact, if the wrong people gained knowledge of what he was capable of, assassins would appear in droves.

Sacred artists follow a thousand Paths to power, using their souls to control the forces of the natural world. Lindon is Unsouled, forbidden to learn the sacred arts of his clan. When faced with a looming fate he cannot ignore, he must rise beyond anything he's ever known...and forge his own Path.

Mark’s new life begins in the worst possible place—a burned-out village haunted by undead. Each morning these ravenous creatures disappear, only to return at night, driven by a relentless hunger. He'll need to stay low and think quick, because trapped and alone in the body of a child, he can’t level up in this new world. At least not yet. Soon Mark will learn that even among the living, safety isn’t guaranteed. When the small town that he ends up in turns out to be at the center of a conspiracy that threatens the world, he'll need to uncover the truth before it's too late.

Arthur lives with his father, a fallen but proud former noble, in Border Village #49, along with the other good folks condemned to toil in service to the Baron. But Arthur has an edge: a stolen heart card that secretly fell into his possession, thanks to a dragon. It’s a priceless source of power for the Baron and the tyrant will kill to get it back. Invaluable, too, to a young man of spellcasting ambitions.
