The Silver Case

Pre-Lunatics presents events just prior to and at the start of case#0: lunatics. It includes Ryo Kazan's psychological decline after Moonlight Syndrome, Sumio Kodai departing from HQ due to an unsettling intuition, and Tetsugoro Kusabi viewing a photo of Toriko Kusabi and Christina. The content directly connects to lunatics, as its final pages align with the beginning of that case.
