During the day, I am submissive in the real world, but at night, in the underworld, I am aggressive. Others work for the underworld, either catching ghosts or monsters. I work for the underworld as a security guard at the Naihe Bridge, responsible for maintaining order. When I encounter uneducated gangsters, I will fight them in my security uniform! When I meet an educated gangster, I take off my security uniform and chase him!
Daytime is the line of life, closer to reality. The adventure line is at night (after midnight), where you work part-time in the underworld.
The first five chapters are the genesis of everything that follows.
There is a heroine, but no harem. The system only exists in the working line and has only explanation and statistical functions.
