VAMPIRE! Giorno Giovanna

Giorno tends to approach many things with a calm demeanor, and demonstrates immense composure even when confronted by dangers he might not understand completely, with Koichi describing him as having a 'shining serenity' in place of where most apprehension should be. However, he can still become anxious when things go south. Giorno rarely allows his anger to get the best of him, but shows moments of tranquil, if not oppressive fury against certain enemies. At his worst, Giorno becomes desperate for solutions to problems and can be seen yelling and breaking out in a sweat when emotionally distressed, though he never reaches a level of panic to become reckless or impetuous. With others, Giorno treats people with the amount of respect he believes they deserve based on his observations of their beliefs and actions. He seems to have inherited traits from both Jonathan Joestar and Dio Brando, with the former's being present towards peers and allies, and the latter's towards enemies. He has a good heart and wants to help out anybody who has demonstrated kindness to him or others, but casually disregards the law. Usually introverted, Giorno regularly maintains a facade of confident boldness, backed up by his intelligence and his natural charisma, to make him look like a flawless person by his peers. This is especially visible upon his first meeting with Bucciarati's team. He switches from a passive and polite demeanor to a self-assured persona when they try to bully him, and impresses the whole team. When alone, Giorno is shown to be more humorous and only in these moments does he allow himself to think about something else than his goal or act seriously. His parents' abuse encouraged his introverted nature and his habit of observing others, resulting in his deductive skills but also making him a silent person until something of importance needs to be said.

Giorno is a teenage boy of average height, a slim yet muscular build, and is far smaller in stature than previous JoJos. He has golden hair of moderate length tied back in a short, braided tail, with his bangs curled into three distinctive oversized ringlets arranged in a row over his forehead. His hair was originally black and unkempt, barely past his neck. But transformed upon awakening his Stand. His eyes, especially present in earlier depictions, sharpen at the end similar to his father's. He possesses a star-shaped birthmark on his left shoulder.

Giorno wears a two-piece suit with a checkered coat tail and several ornate features, including wing-shaped emblems on the collar and a heart-shaped opening in the chest area. The most distinctive feature on his suit are the three ladybug emblems located on either side of his chest and directly below his zipper, matching the appearance of his Stand. Later on, his shoes also have the same ladybug emblem on them. He wears a small stud in each ear.

Giorno is on friendly terms with all the members of the Buccialatti Gang (Fugo Pannacotta, Narancia Girga, Trish Una, Bruno Buccialtti, Mista Guida) except for Abbacchio Leone, with whom he has a slight feud, though Giorno still respects him. Giorno is the son of Dio Brando, but knows nothing about him and probably despises him. Giorno's enemy is Diavolo.
