In a land where the Towers rise high and the Demon War rages, En is part of those who will become Climbers—mages that climb the tower to gain the power necessary to fight back the demon tide. Before that, though, they must enter academies, where they will learn to use their power—and the Marked, a divinely-selected elite cohort, will come into their own special powers. The Marked, those special few, have only been women for as long as history records. Until En awakens into a Mark of his own. Now, he'll attend the Marked-only school, Ascension Academy.

Theo has survived his first five years, and a rather perilous dungeon encounter, in his new fantasy life. But now he's back at the academy, along with his mothers and Gisel, his goblin friend. Surely things will go a lot more smoothly now. I mean, what could possibly go wrong?

Someone once asked: What is stronger? Martial arts or Magic? I answered: Why not simply use both? In a new world brimming with possibilities—Levels, Classes, Skills, Dungeons, and Monsters—I found myself reborn as a noble family’s troublemaker son. As a gamer, a magical world and a lazy life as a rich noble's son should have been a dream come true. But there was a massive catch. An absurd quest threw everything into chaos.

The climb through the ranks often ends with a knife in the back. Slum-dwelling orphan Garrett Walker scrounges for scraps in the wildlands beyond the walls that guard society, salvaging valuables from the ruins of fallen civilization. Offered the opportunity to compete in the Warden Academy entrance trials, Garrett seizes the chance for a better life. However, the academy holds dangers a street rat is ill-equipped to handle and he’ll have to grow stronger while relying on his wits to survive.

The immortal Lifetree, once the source of all creation in the world, has become corrupted. Nightmarish, tainted creatures now fill the realms, and the world calls out for a hero. Nikolas, a warrior resurrected from beyond the grave, has been given the insurmountable task of destroying the evil and bringing balance to the world. He must win the support of four beautiful champions, learn to harness the powers they control, and fight against the chaotic hordes whose very presence chokes the life from the land itself.
