By bringing her voice to West Doroa, the East Doroan singer Queen Malta hoped that she could heal the rift between the two countries. Instead, her murder on stage by an unknown assassin only served to increase the tension between the two countries. Already a country known for its incredibly low crime rate, East Doroa increases security in preparation for war--but security is nothing to the likes of super-genius thief Lupin III!
Still, when he and partner Daisuke Jigen swipe the Little Comet gemstone from an embassy in East Doroa, it's a little convenient that the police seem to know their every move. And worse, before they can even make their getaway, the pair find themselves under the crosshairs of a certain hitman--the same one that killed Queen Malta! Something's fishy, and in order to confirm his suspicions, Jigen visits the cemetery. There, he finds himself staring at his own gravestone. It's a calling card of the sniper, Yael Okuzaki... and no one targeted by him has ever escaped the grave! But why is he only after Jigen, and not Lupin? And things only get more complicated with Fujiko around!
