An adult murder mystery/detective visual novel with 2 stories taking place at the same time. The point of view can be swapped between the main characters, a private detective hired to investigate some very suspicious pieces of art and a government agent assigned to protect the daughter of a Japanese embassy official stationed abroad, at any time to help solve the cases they are working on and interacting with each other at points to progress their stories. The game was ported to Sega Saturn and that version was then ported to Windows, with changes to the games content in both instances, resulting in a 15+ rating.
