Reincarnated as a Ghost

What would you do when you woke up and had skills and strength far greater than what you could ever have imagined? What would you do if you woke up as a ghost...

When a stray soul reincarnated on a strange world with a system telling him that he had a class of a ghost, he had to try and survive against the foreign and strange dangers that lay ahead.

Would he be able to come out to the top? Or at least survive long enough until he found out where and what he truly was...Come find out...
