While the main business at this location is kakuseizai, that part is hidden away in a basement only accessed from behind a secret door and staircase. The main business done here (at least what they tell the locals) is bakecho, or private investigation work. It's a front that has managed to work so far, and hopefully nobody comes around asking questions any time soon. This is an entry for Basemental's #basementalgangs & #simkuza contest.
