I, Bai Qianhan, an orphan with a heart disease who is destined not to live past the age of 25, am also a well-known queen of reasoning. Big fan of Conan. One day when I was seventeen, I finally left this cruel world without care. But I didn't expect that I would actually come to the world of Conan, become the biological sister of Hattori Heiji, and meet little Kudo Shinichi. Alas, is this the legendary heroine Goldfinger? Now that you've come, let's live in peace. I reason that the Queen can also make a name for herself in this world!
