When the warning letter of "The Thief of the Century" Lupine the Third pierced the Tokyo night sky, Conan Edogawa, the "Sherlock Holmes of the Heisei Era", smelled the atmosphere of a twenty-year conspiracy. Behind the sapphire necklace "Tears of Sighs" lies the shocking secret of the Vespagna royal family, which also leads to the Karasuma Group's "immortality plan" spanning three hundred years. From the astrological mechanism of the Ginza Tower to the bronze chamber in the deep sea of Bermuda, from the clock tower showdown in London's Fog City to the fateful reincarnation in the time corridor, the two old enemies are forced to join forces to solve the mysteries dusted by history on the battlefield where reality and illusion intertwine. Conan discovers that he has become the key "qualified person" for this conspiracy, and the layout of his father Yusaku Kudo twenty years ago is pushing him into the center of the whirlpool of fate in an unexpected way. When the Geminid meteor shower lights up the sky again, truth and lies, the past and the future will all usher in the ultimate showdown in this game about life, death and immortality.
