musical investigation

Exploration Stage: Clock Tower
From: Carlos Light
Description: If I believe what Vila says she heard from the Alliance, their inventions bring happiness as well as profit. In those dark days when the fog almost engulfed everything, I used to look forward to the concertos played by the mechanical violins. Was that violin, by any chance, invented by the Alliance? Let's find out together.
Completed: Thank you. You've helped me again. The sound this violin makes is delightful and relaxing. It reminds me of the old days. It's an interesting idea. It started out as an ordinary violin, but I modified it to have more vibration. But there doesn't seem to be any sign of alliance. I guess it is also invisible to the naked eye.
