Mitsu has been Shiro’s personal servant and best friend since they were both six years old, and he’s been in love with him for nearly that long. While Shiro takes lovers of both sexes, the gulf between their social classes is so vast that Mitsu has never spoken his feelings aloud. When Shiro meets the beautiful Lady Keiko, he’s instantly infatuated. His affection soon turns to obsession, and Mitsu resigns himself to a life of unrequited love. But as Mitsu looks deeper into Keiko and her motives, he realizes that Shiro is in grave danger. He will need all his courage—and some help from a master of the occult—to save the life of the man he loves.
