TestIn modern-day Japan, mysterious dungeons have suddenly appeared across the globe. Rei Omomo, a true introvert who avoids society whenever possible, turns out to be the only person in the world who has reached the maximum level inside these dungeons. Having severed all ties with the outside world to devote himself entirely to dungeon exploration, Rei lives quietly—until the day he saves Yuria, a famous and irresistibly cute streamer with 10 million subscribers, from a life-threatening crisis.

His accidental rescue goes viral, catapulting him into the spotlight through dungeon livestreams. Despite wanting nothing more than a peaceful, solitary life, Rei is pulled deeper into the growing mysteries surrounding the dungeons—mysteries that involve the underworld, hidden conspiracies, and even national governments.

A reluctant hero, an unexpected partnership, and a world on the brink of the unknown… the adventure is only beginning.
