Manga/Anime Differences

 * The Aztec Ritual at the beginning wasn't shown in the anime, but is alluded to in the ending credits.
 * George mentions that he would have rewarded Dario with money if he had not lost his wallet. This wasn't in the anime.
 * Jonathan and Dio nearly fight in the anime after Danny is kicked, only to be interrupted by George. This is not in the manga, where it cuts to inside the mansion.
 * In the anime, one of the bullies states that he doesn't have a grudge against rich people, but doesn't like people like the Joestars. In the manga, he says he hates all rich people.
 * There is a scene after Jonathan is dismissed from the table due to bad table manners, where he is crying in his bed. A picture of his mother is shown above his bed. Jonathan then eats the chocolate found at his bedside. This is cut from the anime.
 * There was a manga only scene before the boxing match between Dio and Jonathan that involved Dio gambling all of his allowance on the fight.
 * Dio tells the crowd of people not to tell Jonathan his fighting techniques, but in the manga he tells them not to tell Jonathan how to make his homemade firework.
 * A short scene where Jonathan's watch is "borrowed" by Dio before meeting up with his friends and Jonathan being told this by Dio is not in the anime.
 * The scene where Dio discusses with George about the Stone Mask, the writing inside, and how George got it is not shown in the anime.
 * Originally, Jonathan was smoking a pipe in the tree, while in the anime he is just sitting.
 * Jonathan briefly fights the group of boys who accuse him of being a snitch. In the anime, they simply run away.
 * Jonathan's dates with Erina and them relaxing in a lake and discussing frogs are condensed in the anime to only being shown.
 * The entire flashback of how Jonathan met Danny and how Danny saved Jonathan's life when he was 5 wasn't shown in the anime.
 * Jonathan is not hit in the head by a thrown stone before being told why Erina's avoiding him in the anime.
 * In the manga, the butler opens the incinerator and Danny jumps out from it on fire. It was only revealed that Danny was in the incinerator when Jonathan got home, in the anime.
 * The anime cuts out a few short scenes where Jonathan scares away a crow before seeing Erina walking past and Jonathan hitting the tree in anger, when Jonathan is walking home and talking about how depressed he is, and when he gets home and the butler apologizes, instead cutting to Jonathan at Danny's grave.
 * The anime mentions Jonathan crying at Danny's death, but does not show him directly in bed, only showing him in the sheets.
 * Dio thinking about how he must be calm and how he underestimated Jonathan is shown as nighttime in the anime, but daytime in the manga.
 * Several scenes after the carriage incident are not in the manga.

Trivia

 * The arrows featured during the internal monologue scenes are an homage to one of Araki-san's other works, namely Magic Boy B.T.. In the manga, they appear whenever BT (the main character) is scheming.
