Hi! My name is River, the funny ghost from Underworld Office. I am a good person but can be a jerk sometimes. 

My body is full black because of the evil deeds. Once I have done enough good actions, it will get white and I can go to the other side. Anyway… it’s extremely hard to create a bit of light when you are all black
I love it here, working with everyone at Underworld Office. Except Boss. He such an old fashioned guy. I always try to tease him but he would hit me with his fan

A cheerful ghost in the Underworld Office

 I am the founder of Underworld Office. I has lived as a ghost for 400 years. I was a shaman in Joseon Dynasty, Korea. 

My body is full of black because of the evil deeds. I am gaining good deeds by monsters and helping other ghosts. Folks say I have cold personality and a dark and sarcastic sense of humor that other often misunderstand. I am quite opposite to my employee River. She often tells jokes. I often hit her with my fan and complain about her behavior but I… don’t hate her at all.
