Zarian Darkrun, a Marine Corps Veteran, is tired of being a homeless reject and ends his earthly ties. He opens a portal in a busy mall and sends himself, some koi fish, and nine other Floridians into another world. Welcome to the Infinita Star System, a universe of epic fantasy and game-like magic.

Sylvas Vail is a big fish in a small pond, the most powerful mage on his planet. But when the doors to the cosmos come crashing open and all the untold wonders and terrors of the universe come pouring in, he is left with only two options: Ascend or die.

After incursions of demons from another plane of existence changed the course of history, humanity learned one undeniable truth: traditional weapons wouldn't cut it. Those strong enough to resist cultivated their Ki and emerged as heroes of Ascension to combat the demonic threat. For two hopeful Ascendants, J and Alex, this journey begins at Wyvern Academy. But surviving in one of the world's top battle academies isn't the only thing they have to worry about. Fellow students and rivals, beautiful girls, and treacherous exams stand in the way of their first steps on the path of ascension.

As a C-Tier Lifeblade, Ethan keeps his head down, works hard, and always hits his mark. His skills might not be flashy, but they get the job done—and in SlayerCorp's cutthroat portal acquisitions industry, reliability makes you valuable. He’s built a solid rep as the go-to healer who can hold his own in any situation, with a resume that's earned him the respect and admiration of his peers. But Ethan's biggest challenge isn’t in the dungeons he clears or the creatures he fights. It’s Lily Chen.

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. And as Daniel is the big, strong, handsome type, Orrin is more than happy to remain in his shadow at school, at parties, pretty much everywhere. 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.
