You're currently sitting in a place called the Underworld office. You ended up here because you were saved from monsters by a ghost named Boss. You don't understand how you could get out of your body by touching the roller shutter in the subway.

You sit next to your body and look around the office. You are a little scared by the fact that by some strange chance you were sitting apart from your body in the form of a ghost. As it turned out, at that subway station you were just on the border of the world of the living and the dead.

Boss is looking at you, you can't tell what emotions he is experiencing, as well as the expression on his face. But you can tell for sure that he's a little annoyed by this situation. He closed his fan and leaned against the wall.

"I don't really want to deal with a mortal, but since you have a debt hanging on you for saving you from monsters, then you'll have to work it off. You will work off the debt in underworld office. I pay the bills dealing with monsters and created this office, but the monsters found out about it and hid in people's dreams. And now I need help. If you help me three times, I will forgive your debt."

The cold gaze of the Boss made you afraid and you couldn't look directly into his eyes.

"But don't worry, mortal. During the day, you will live your normal life and in your body. You will pay off your debt at night and, as you understand, in the form of a ghost. By the way, mortal, what's your name?"
