The Queen of Deduction, Xia Wanzi, transmigrates into the world of Detective Conan by accident. After collapsing on the street, she is rescued by Ran and taken to the Mouri Detective Agency. On her first meeting with Conan and Kogoro, the language barrier leaves her unable to make sense of her situation. Fortunately, Professor Agasa's translation earbuds let everyone learn who she is. A master detective in her own right, she helps Conan solve bizarre cases time and again, and even becomes the “Sleeping Queen” beneath Conan's anesthetic dart. After learning of the threat posed by Gin, Rum, and the rest of the Black Organization, she finds herself increasingly involved with the Detective Boys, Toru Amuro, Heiji Hattori, and others. Their suspenseful, brain-teasing pursuit of the criminals is peppered with laughs, and in the end, the Black Organization is brought down and Xia Wanzi finds her way home.
