A mysterious lens that was once part of a special Kamera.
They say that in the distant past, the legendary Kitsune Saiguu left a catalyst for the then-Hiiragi Clan head, Hiroshi, as a tool to be used in exorcisms. The Hiiragis would have a special Kamera made to order from overseas with that catalyst mounted on its lens assembly, before giving it back to the Grand Narukami Shrine as a symbol of their friendship. That Kamera was said to have been able to record thoughts and memories, and though the complicated components may have rusted away over time, the specially-made lens can still see that which does not exist in the present world.
