Muramura 071312 696 File

Another angle is to treat "Muramura 071312 696" as part of a puzzle. The numbers could be coordinates, a combination, or a date linked to an event. If 071312 is July 13, 2012, maybe the story involves an event from that date. The 696 could be a room number where something important happens. I should also consider cultural references, like the significance of certain numbers in Japan. For example, 7-13-12 might relate to lucky numbers or historical events.
