The World of JoJo's Bizarre Adventure: A Distinct Universe

JoJo's Bizarre Adventure is a legendary anime and manga series created by Hirohiko Araki, known for its generational saga, unique art style, and introduction of "Stands"—supernatural manifestations of a person's fighting spirit. The series follows the Joestar family across various parts and timelines, each with a different protagonist bearing the "JoJo" nickname.

The cast of characters in JoJo's Bizarre Adventure is distinct, vibrant, and entirely separate from the world of Demon Slayer. To truly appreciate the diverse and extraordinary lineage of the Joestar family and their allies, you might want to explore a comprehensive overview of its main characters. .

Exploring the Joestar Lineage

The JoJo's Bizarre Adventure saga spans across many generations, introducing a new "JoJo" as the protagonist for each major part. While Kyojuro Rengoku is not among them, the Joestar family tree is rich with compelling heroes, each with their own bizarre adventures:

  • Jonathan Joestar (Part 1: Phantom Blood): The noble original JoJo, a master of Hamon energy.
  • Joseph Joestar (Part 2: Battle Tendency): Witty and strategic, he's known for using both Hamon and his Stand, Hermit Purple.
  • Jotaro Kujo (Part 3: Stardust Crusaders, and later parts): The stoic grandson of Joseph, famous for his powerful Stand, Star Platinum, which can stop time.
  • Josuke Higashikata (Part 4: Diamond is Unbreakable): A kind individual with the ability to repair and reshape objects using his Stand, Crazy Diamond.
  • Giorno Giovanna (Part 5: Golden Wind): Son of DIO, aspiring to be a "Gang-Star" with his life-giving Stand, Gold Experience, which evolves into the reality-bending Gold Experience Requiem.
  • Jolyne Cujoh (Part 6: Stone Ocean): Jotaro's daughter, the first female JoJo, who can unravel her body into thread with her Stand, Stone Free.
  • Johnny Joestar (Part 7: Steel Ball Run): A determined former jockey whose Stand, Tusk, harnesses the Golden Spin.
  • Josuke Higashikata (Part 8: JoJolion): An amnesiac fusion of two individuals, wielding the bubble-creating Stand, Soft & Wet.
  • Jodio Joestar (Part 9: The JOJOLands): The most recent protagonist, with his Stand November Rain controlling the weight of raindrops.

Why the Crossover Confusion?

It's natural for fans to sometimes conflate characters or elements from different popular series, especially when they share certain thematic or aesthetic qualities. Both Demon Slayer and JoJo's Bizarre Adventure are visually striking, feature protagonists with incredible resolve, and showcase intense, often dramatic, battles against formidable foes.
