Since the K century, night ghosts have descended into the night and they feed on human blood. Panic spread from the West to the world. The dark night security industry emerged at the historic moment and is developing rapidly. It is divided into public and private branches. Private, they are major security groups; public, they are the night arrest department within the system.
Youxu is a young master who came to the warm Seris with his uncle when he was young. He had a strong interest in hunting night ghosts, and at the age of 16, he joined a poor security company (not an employee, he was a shareholder who held shares and did not receive a salary).
However, You Xu was so preoccupied with hunting that she didn't expect that her neighbor and employee who lived across the door suddenly died, and she had an adopted son at home. Out of humanitarianism and because the child's cooking was particularly delicious, You Xu took him in.
But the child's identity doesn't seem simple.
