Boukensha Zettai Korosu Dungeon

Dungeons are elaborate mazes filled with opportunities for heroes seeking recognition and wealth. Eine and Nacht, however, do not share this enthusiasm. Unlike other individuals who have been reborn and enjoy isekai experiences, they are forced to work within the dungeon. Their responsibilities include cleaning up the aftermath of adventurer encounters, regardless of the outcome. As they handle the disposal of bodies, they consider altering their workplace to become a deadly environment where adventurers do not return. Their goal is to create a place so dangerous that it deters adventurers, allowing them some peace.
