lurking threat

Exploration Stage: Foggy Backstreet
From: Carlos Light
Description: I can hardly remember anything about that Violet person, but I have a bad feeling about something. Oh, why did you push me? I see, a dart is stuck in the wall right next to me. This is a trap! Oh, I completely forgot about it. There must be a trap detector around here. Please look for it with me.
Completed: I am glad you found the trap detector. This looks like a simple device, but it's very elaborate, based on the collector's blueprints. Take a good look at it. If the detector flashes, it means there is a trap nearby. There are a lot of traps in the pawnbroker's warehouse!
