I'm a Ghost and I'm Living in the World of the Dead.

Having been a ghost in the underworld for decades, one day I can suddenly return to the earth and become a human again. What? Actually you still have to go to the company to work? How come there is no normal person in such a large company? The boss is very awesome, and his colleagues are very fierce. I originally just wanted to keep a low profile and clock in and show full attendance, but I am so good that I can trigger a series of big events just by taking on a task. There is no other way but to show off. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
