Ghost Reaper

Strictly speaking, this is just a novel. There are no power-ups, adventures, or harem, and it doesn't even have any decent supporting characters or female characters. It's simply a day-by-day account of an ordinary person. I wanted to write something, so I started, and then I couldn't stop. Is it a wondrous encounter, a wild fantasy, just a dream, or perhaps nothing more than someone else's dream?
