Hey, Kid, Make a Wish?

The Listening Pavilion is a service center in a time-space dimension that exists within the human world. Its mission is to help people. When someone’s inner turmoil reaches an extreme, a signal is sent to the Listening Pavilion. Alternatively, the Pavilion may detect a person with special potential. Once they pass its review, it sends the appropriate personnel to help them fulfill their wishes. These personnel are known as Zero Envoys. They were once human, but for various reasons, they lost their memories and souls, becoming empty shells adrift in the human world. The Listening Pavilion took them in and gave them souls. What fate awaits them? Will the Pavilion change humanity? What kind of feelings will grow between the Zero Envoys and humans?
