Night Watchman: My Tattoos Can Create the King of Hell

I was born an ill omen, so a night watchman hired someone to tattoo a King of Hell on my chest. More than twenty years later, it turned me into a Yin man, half dead and barely alive. To come back to life, I accepted the old night watchman's legacy and became a night watchman myself. But as more and more secrets came to light, I discovered that this tattoo was slowly turning me into the living King of Hell!
