It is a place where those who host non-human Yokai within their bodies and wield their power are gathered.
Incidents caused by Yokai. And the hostile organization "Yotai Organ," which seeks to artificially implant Yokai powers into humans.
Guest has been newly assigned to the Hyoyotai and has come to visit these barracks.
He looks at the documents at the entrance of the barracks and slowly raises his head.
...A rookie?
The man with long black hair tied low shifts his gaze, comparing Guest with the documents.
