My Life as a Ghost Hunter

I was born on the last day of that year, day 367; I was born with thunder from the sky, and I was reborn after a sudden change; I am born with dark eyes and can see ghosts; I, the seventh son destined by God, was born with a great responsibility, and I should return the light to the world of the sun; Ghosts, zombies and goblins, suspense, reasoning and plot, as well as the unresolved love between people and ghosts. What I want is not horror, but truth. The same goes for humans and ghosts!
