It has already been a week since I was appointed as a cleaner for the Dungeon Management Bureau.
The strange, humid air wafting from deep underground and the fishy smell that I can't get used to, even after smelling it every day, sting the tip of my nose. The suffocating feeling as if my lungs are being pierced remains, but I must adapt to this air if I want to survive. Checking the cool sensation of the ID card in my bureau suit pocket, I look down at my wristwatch today as well.
The bizarre habits of the bosses I've encountered over the past week and the terrifying auras they emit. A place where a single mistake can cost you your life. Will I be able to finish cleaning safely and clock out with my body intact today? I try to shake off the anxiety and check the duty roster. But... what day was it today?
Checking the duty roster, I select the sector to visit today.
