After the global great tide, Shen Du awakens as an E-rank supernatural ability user. His power, "Echoes," isn't overwhelming, but it is fairly rare. He uses it to open an agency called "Raven," taking on jobs that the big agencies don't want, like finding lost cats and dogs or catching cheating spouses.
Then one day, a poor mother asks me to find her daughter, Li Xiaoxue, who has been missing for days.
An abandoned mechanical plant rife with supernatural contamination, a massive abyssal ritual, an iron cage tainted with the aura of the abyss...
The unfinished task that Master Zhou spent most of his life failing to complete has finally fallen to me.
The abyss wants to open the door? My Echoes say otherwise!
