Copy Cleanup Bureau

In the future world, disappearances occur frequently, people are panicked, and society is in turmoil. The dungeon game was born out of the blue, saving the world in danger with one game. The Dungeon Cleaning Bureau is the most mysterious branch among them. As its name suggests, the bureau was created specifically to clean up "dungeons". As the "ace" of the cleanup bureau, a team composed of all S-class members will enter a large S-class "dungeon" to clean up. But who would have known that many "NPCs" in the "dungeon" that were supposed to be controlled by the corresponding main god actually collectively developed self-awareness and hindered the work of the S-class team, with the intention of trapping everyone in the "dungeon". There was a large-scale natural disaster in the past, and "NPCs" were chasing after them later. How should the S-class team escape the "encirclement" and return to the real world?
