The Investigators
Kageyuki Shiraishi, Kei Okazaki, Takeru Sasazuka, and Aiji Yanagi make up the main cast collectors tend to look for, most often as acrylic stands tied to specific outfits or story arcs.
Smaller Keepsakes
A stained-glass keychain line and a handful of pin and can-badge sets round out the smaller-format side, generally easier to track down than the stands.
