Arsène Lupin III mails Inspector Zenigata an invitation to his own wedding: he is marrying Rebecca Rossellini, the young head of the Rossellini business empire and a thief in her own right. The ceremony in San Marino is cover for lifting the Royal Crown of Libertas, and the marriage outlasts the heist to complicate every job that follows across Italy. In his blue jacket, Lupin works with Daisuke Jigen and Goemon Ishikawa while Fujiko Mine plays her own hand.
