Born Haruno Shiobana, Giorno is the son of Dio (fathered using Jonathan Joestar's body, which makes him part of the Joestar family) and a Japanese woman. As a young child, his mother remarried to an Italian man, and they moved to Italy; hence, Haruno Shiobana became Giorno Giovanna. Giorno's great ambition in life is to become a mafia boss (a "Gang Star"), and as such, he eventually joins the mob squad Passione. Though he is its youngest and newest member, he quickly proves his mettle and eventually becomes the de facto leader of the group. Unlike typical mafia bosses, he wanted to give divested riches to the poor, giving him an agenda similar to Robin Hood. He eventually influences all of Passione—all but their boss, who later became their worst enemy.

Hestia is a beautiful petite woman whose appearance can be considered to be between a little girl and a female teen. She has roundish blue eyes and black hair going down to her hips tied in a twin tail fashion with a white ribbon on each tail. She has a small stature which further emphasizes her big breasts; hence the nickname "Loli Big-boobs." Hestia's usual attire is a white one-piece dress with blue ribbons on her collar and one just below the chest that goes around her arms, and a pair of white gloves. She is frequently barefoot, but does occasionally wear a pair of white flip-flops. Hestia is an energetic, kind goddess who sees potential in Bell. She is a hard worker, and works jobs to support the two while Bell goes off to the dungeon. Hestia tends to be shown as very petty and gets jealous easily when girls, namely Aizu, show interest in Bell, because she is deeply in love with him, or they are the reason for his strength growth. Hestia is shown to have a lewd side, as she often sneaks into Bell's bed and sleeps with him, even getting overjoyed about it. Despite seeming mature and dependable toward Bell, Hestia is in truth, a lazy goddess, as she couldn't get a job or put effort into work until her friends kicked her out and shown to be a glutton, always eating food from others as she couldn't pay for meals. After descending to the Lower World, Hestia was taken care of by her friend, Hephaestus but was soon asked to live on her own and gave her a room at an abandoned church. Hestia tried to create her own familia but wasn't able recruit even a single person. After failing to recruit for the 50th time, she noticed Bell Cranel and decided to secretly follow him. Hestia noticed that Bell was trying to enter a familia but was rejected multiple times and is in the same boat as her. Hestia then took the chance to recruit him which Bell happily agreed upon; becoming the first member of her familia. She took Bell to a bookstore, the location she already decided beforehand, and granted "God's Grace" to her first dependent. (Source: DanMachi Wiki)
