Where to get this case:
The case starts with that weird "Noise" people complaining about in the Buzz App around the Yokohama 99 office.
If you stand in this area, you will see people say that it's since "This Woman" walked past.
Look out for the woman in red and use the Detector on her.
HEAD TO MOMOYAMA'S CLUB
It's right around the corner.
Case is closed after interacting with the couple.
