<P> The manga begins in 2001 , when the Diamond Is Unbreakable character Koichi Hirose goes to Naples at the request of Jotaro Kujo to find someone known as Haruno Shiobana and get a skin sample of theirs . Shiobana turns out to be a middle school student named Giorno Giovanna -- which sounds similar to `` Haruno Shiobana '' -- who is the son of Dio Brando . Giorno attempts to steal Koichi 's luggage , but is stopped by Koichi 's Stand , Echoes Act Three . Giorno recognized his power as being a Stand power similar to his Gold Experience , a Stand that can give life to inanimate objects . The story then follows Giorno as he tries to become a boss of the mafia in order to make Naples a better place and help its people , specifically where availability of drugs to young people are concerned . After an altercation with gang member Leaky Eye Luka , he attempts to join Passione , an organized crime group that employs many Stand users ( essentially , his vision for Passione is akin to Robin Hood 's band , in contrast to the sheer powerlust of its current leader ) . He is approached by a member of Passione , Bruno Bucciarati , who suspects him of killing Luka . During the fight readers are introduced to Buciarati 's Stand , Sticky Fingers , that can place and open a zipper on any surface . Bucciarati challenges Giorno to complete the rite to join Passione , and therefore visit the Capo , Polpo , in prison . </P>
