An ex-salaryman had made deal with a mysterious entity, and now he was in the other world. He was told that he wouldn't get any special powers but he wasn't worried. A little science and his rough upbringing should be enough for him to survive whatever thrown at him. The man didn't want any glorious adventure or anything to do with great romances. He just wanted to have some fun, as long as it lasted.

Author notes:

- The English might not be perfect, but give the story a chance if below notes are agreeable.- Aimed for adult audiences, but focused on plot rather than just getting laid.- Fast-paced but the litrpg mechanics, plots, etc are revealed in stages.- Characters will die as the plot sees fit.
