This Dungeon Manager Is Too Strong!

One day, the world was thrown into chaos when an enigmatic figure, claiming to be a divine being, took over every screen on the planet—television, internet, even billboards. This so-called "god" declared that humanity had hit a plateau, its progress stagnant and uninspired. "If things continue like this," the figure said, "the evolution we seek will never come."

Their solution? A radical one. "I will infuse fantasy into reality. As the first step, I've chosen a handful of humans around the world to create and manage dungeons. The rest of you will explore these dungeons, face their challenges, and take home the spoils. Use these treasures to evolve your society."

And just like that, random individuals from different countries were chosen to become dungeon masters. Each one tasked with maintaining a dungeon filled with traps, monsters, and mysteries—an impossible job thrust upon them without warning. Japan was among the selected nations, and one of its own, an ordinary person, suddenly found themselves bearing this monumental responsibility.

This is the story of that person's unexpected journey into dungeon management—a task that could very well shape the future of humanity.
