Tantei Jinguuji Saburou: Kind of Blue

As the game begins, we learn that Yoko Misoni, Saburou's invaluable assistant, has left the firm. Even a tough guy like Jinguuji feels the pain and misses his former employee. Despite the pangs, Saburou trudges ahead with cases and detective work. The new scenario in Kind of Blue places the super sleuth on assignment against a crime boss and on the hunt for a missing singer from a local jazz bar. As usual, portly police detective Sanzo Kumano provides support and advice during the course of the game.
