A mountain treasure, a princess, and a baby? That’s a little more than “as you wish”!

Lupin’s heist on a treasure-packed dirigible goes sideways twice over! A gang of masked air pirates beat him to the punch. And among their ranks is the young blonde woman Yutika, who sends Lupin into the drink. But first, he manages to swipe a bag. Its contents: a baby named Rahm and a small empty case bearing the coat of arms of Shahalta, a secluded nation rich with helium deposits. With Rahm in tow, Lupin lures the air pirates to him so he can capture the pieces of the puzzle he needs to find and open the legendary Shahaltan treasure vault. Suddenly, a private army of assassins working for the sinister businessman Korschal raids the gang’s hideout. Now Lupin, Jigen, and Rahm must help Yutika face her destiny—and true identity—in Shahalta.
