The princess of the demon world lived in the world, was adopted by a human couple, and named Lan Xizi. Sixteen years later, she grew up to be an ordinary human girl, but the power of the demons in her body was ready to move. Once this power broke out, the consequences would be disastrous. In order to protect her from being demonized, her adoptive parents looked for ways to save her and set rules for her not to go out after dark, but this was not a foolproof method after all. The door to the demon world was still opened, and the demons invaded the human world on a large scale. In order to protect those around her from being harmed, Lan Xizi chose to join the exorcist organization Nightingale and became a professional exorcist - the Night Guard. Later, as things continued to develop, Lan Xizi's true identity gradually emerged. On one side were her friends and relatives, and on the other side were her own tribe. Whether she is a human or a demon, what choice should Lan Xizi make?
