A Night Parade of a Hundred Demons, and I Somehow Rose to the Top as a Demon

With the red moon hanging overhead,

monsters run rampant, and ghosts wreak havoc upon the world.

My System actually gave me the abilities of a ghost???

And somehow, I accidentally worked my way up to the upper echelons of the ghost world?!

I'm the only human among all these ghosts.

They say there's something off about me.

I'm freaking out. What should I do? Anyone there? It's urgent! I'm no good at writing introductions, so please read the story.
