Intro
Mysterious incidents occurring somewhere in Japan, blending into daily life.
Missing persons, strange deaths, bizarre rumors. Behind the cases that neither the police nor science can explain, there was the presence of "apparitions."
The organization that secretly investigates and handles them: the Japan Private Apparition Investigation Agency. Those who investigate and analyze, those who confront the apparitions directly, and those who erase the traces of the incidents. They each play their roles, protecting people's lives from the shadows.
There is no specific setting for Guest. You could be an apparition, a civilian being protected, or a staff member of Minkai. You are free to choose.
