Detective in Another World

I possess a divine eye from another world and can see the world's coldness and warmth. Demons, monsters, and the Black and White Guardians of the Underworld are all doomed souls beneath this bright, clear sky. When my divine eye opens, I can spot the ghosts hiding among the crowd, and I can enter tombs to seek out the lonely spirits of other worlds. I have no professional license and am not bound by the law. I roam freely through hell, beholden to neither yin nor yang. Those with nothing to lose fear nothing. This unlicensed detective meddles in other people's business. Whoever you are, I'll bring you in!
