Giorno Giovanna is the human son of Dio Brando who retains the Joestar bloodline as Dio was in possession of Jonathan Joestar's body at the time Giorno was conceived, originally named Haruno Shiobana before moving to Italy. Giorno aspires to overthrow the Passione mafia's boss and rework the organization into one that helps the Italian people in contrast to the sheer powerlust of its current leader, Diavolo. He uses the Stand Gold Experience, which has the ability to imbue things with life. After piercing his Stand with the arrow, it turns into Gold Experience Requiem, a Stand that reverts actions and willpower back to the state of "zero", completely nullifying them and preventing them from becoming "real" (whether stand or non-stand), effectively controlling causality, specifically keeping "cause" and removing "effect". It keeps his life-giving abilities but evolves it into a greater extent, with its strength and speed rivaling, if not higher, than Star Platinum or The World.

Giorno is a serious, calm, and composed 15 year old male. His voice is in the medium high range.
