Summary
Bruno Bucciarati is stunned by Giorno Giovanna's bold declaration to join the gang, and get rid of the drug plaguing Neapolis. Demonstrating his good heart when nearby children hit him with a football balloon and giving it back to them, Bruno decides to give Giorno a chance at changing things. Bruno will tell his gang that he hasn't found the culprit and will enable Giorno's infiltration. However, he warns that in the eventuality Giorno is found out, he won't lift a finger for him.

Walking through the busy streets and dark alleyways of Neapolis, Bruno describes to his new ally how his gang, Passione, works. Passione oversees everything in the city, and their Boss is very secretive, as no one knows his real name or even his face, orders coming through lieutnants. Bruno tells Giorno that one of such lieutnants, Polpo, awaits him inside a prison. After going through a body check surrounded by heavily armed guards and being told that no traffic is allowed between them, Giorno finds inside in a dark corridor. When the lights switch on, Giorno sees a small empty cell; however, the "bed" stands up, revealing Polpo a humongous obese man. Polpo chitchats a bit with Giorno, revealing the many luxuries hidden inside the walls of the cell, and proposes him some wine, which Giorno refuses as the rules of the prison dictacte. Polpo replies that what people say and what they do are different and carries on to the interview.

When Polpo asks Giorno what he is capable of, Giorno chooses to hide his Stand and expose his pickpocketing abilities and his ear trick. Nonetheless Polpo replies that in their line of work, being trustworthy is more important than any talent. As a result, Polpo gives Giorno a lit lighter and tasks him to keep it alight for 24 hours, to test whether he can be trusted even when no one's looking. Warily taking the lighter, Giorno must now pass the body check and hides the lighter in his fist. When the guard asks to see whatever Giorno is carrying, he turns the lighter into a flower, keeping a flame hidden inside the petals, and manage to go through the prison security checks.

Giorno heads to his current home, a small apartment in a high school. Setting up his lighter to keep it stable and protect it from the wind, Giorno suddenly hears his door opening. Spotting Koichi Hirose who's managed to find him, Giorno must hide outside of the window, unable to intervene as Koichi searches the room for his passport. Cornered, Giorno attempts to transform a lamp into a snake biting into the bread holding the lighter, but the snake accidentally burns itself. Koichi spots the lighter but is fortunately distracted by his passport, allowing Giorno to snatch the lighter unnoticed.

Now walking away with his lighter in hand, Giorno again rants about his dream, but in his distraction, doesn't notice a splash of water a janitor was throwing around to clean up the high school playground. The lighter is extinguished, suddenly rendering Giorno's efforts moot. In his despair, Giorno lets the friendly janitor attempt to relight the lighter, which he does effortlessly, and gives back to the young man. Stunned, Giorno doesn't understand why the lighter could be so easily switched on, and suddenly sees a Stand walking by and disappear behind a column. It suddenly reappears from the shadows, and announces to the janitor that he's relit the lighter and is given a "chance" to prove himself. Before Giorno can intervene, it grabs the soul of the janitor, pulls an Arrow out of his mouth to impale the janitor, killing the old man instantly as he didn't have the potential to be a Stand User. The janitor falls dead from the staircase into Giorno's arms, and the enemy Stand spots Giorno, immediately jumping to attack.

Manga/Anime Differences

 * Instead of meeting up in front of the prison holding Polpo, Giorno and Bucciarati are seen walking together through various streets until they reach the prison.
 * When Giorno comes up with ways to show Polpo that's he's talented, he is shown stuffing his ear back into his head. The ear that he stuffs is also his left ear, not his right like in the manga.
 * Polpo's paintings of 's , and 's Vairumati are replaced. His line referencing them is also omitted.
 * When Polpo likens intelligence or talent to the piece of cracker stuck between his teeth, he flicks said piece at the window.
 * The prison guards actually point their guns at Giorno when the female guard orders him to partake in a second body check.
 * The sports team asking Giorno to take the picture of them in pyramid formation can be heard collapsing as he walks away.
 * Giorno no longer sits down in relief once he's gotten the lighter to his desk.
 * Koichi is distracted by his passport burning after he celebrates finding it.
 * The time of day suddenly changes to late afternoon the instant the janitor relights the lighter, setting the stage for Giorno's battle against Black Sabbath.
 * Black Sabbath first disappearing out of sight happens with the camera passing behind Giorno's head, rather than the Stand walking by a column.
 * In the manga, when Black Sabbath grabs the janitor's soul, the janitor exclaims that he cannot move and asks for help. In the anime, he stays quiet the entire time.
 * Black Sabbath speaks to Giorno after the latter steps into a nearby shadow, rather than just noticing he's there.
