One night in June fourteen years ago, ten-year-old Yi Mingyuan signed a work contract with the woman in black who broke into the house, and from then on he began a job called " patrolling the world ".
From then on, her world and time were split into two, the everyday and the extraordinary pulled her into her arms and tore them apart.
On Christmas Day when she was twelve years old, she finally heard its voice in its entirety, and because of it, she finally decided to try to live again.
Full of bloody and dirty work, packed with daily life of human viciousness, she nonchalantly changed from a cowardly person to a heartless monster.
Concept: This world is inherently weird and crazy.
