Trivia
- This part is notable for taking place in a fictional setting, without traveling to any real locations.
- Leaving the Tarot and Egyptian mythology in Part 3, Part 4 primarily references popular (rock) music in its names.
- Araki states that it is possible that JoJo's Bizarre Adventure could have ended with Part 3 since the resurrection of DIO was the last plot element of precedent.[1]
- The title of this arc was formerly translated as Diamond Is Not Crash.[citation needed]
- This part is notable for having one of the most drastic changes in art style as it progressed. At its inception, it took on the muscular, Fist of the North StarFW inspired look that was present in the previous three parts. Around the middle of the part, the various characters took on a more youthful appearance, particularly in the case of Josuke and Koichi. By the end of Diamond is Unbreakable, the manga adopted the glamorous art style in which characters go from very muscular to athletic that would define the visual presentation of Vento Aureo and Stone Ocean.
