Job Transfer for All: Others Fight Monsters, I Contain the System

A hundred years ago, a game system called "Sky Curtain" covered the world. Dungeons, monsters, professions, equipment and levels have become the laws of reality. The city relies on the source crystals produced by the dungeon to maintain energy and defense. Eighteen-year-old citizens must participate in the job transfer ceremony. The combat profession enters the dungeon, and the life profession is responsible for logistics; those who cannot change jobs are called "blank slates."
