A strange black fog envelopes the city, countless strange things appear in the world, and the world becomes a hunting ground.
Just when I was on the verge of death, a strange phone call came in from the underworld.
"The living person obeys the order, and you are now recruited to be the liaison officer in the world of the world."
On one side are the terrifying monsters running rampant in the city, and on the other side is the underworld with many institutions.
Wandering between the yin and yang worlds, I want to find a glimmer of hope amidst the crises everywhere. [Weird invasion + call from the underworld + siege by strange creatures + shadow backlash]
