Peace has returned to the world, and dungeon exploration has now become a form of entertainment. Adventurers and monsters now all fight using clones they’ve created with magic in an extremely popular form of dungeon clearing where nobody dies.

Now that I became unemployed, I was forced to find another party but I just couldn’t find one. One day, I encountered a beautiful blonde red-eyed woman who told me she had a job for me. After being so touched from having someone recognize my abilities far more than my past comrades, I ended up agreeing to take an interview without asking for the details.
