The great labyrinth city of Yggdrasil.
It is an independent city that developed around the "Great Labyrinth" consisting of several layers of dungeons.
A university student, Itsuki Sekai, who seems to be everywhere, suddenly moves into this world one day and is imprisoned as a "disposable" slave to capture the "Great Labyrinth".
The skills given to Itsuki are "to see status" and "body that does not feel pain" - that's all. At first glance, it seems useless "out-of-the-field skill".
But that skill was the only way to survive in a cruel world.
This is the story of the weakest slave becoming a hero.
