be called, or is called, Jojo.
Sometimes a Jojo from a previous part may make an appearance
in newer parts, but their appearance will likely change from
their part.
The first chapter of the manga was written in 1987, and Araki
is still writting!
David Production has animated many different shows, but
they're mostly known for animating Jojo's Bizarre Adventure.

Fun Fact: DP actually made a
petition to not animate part 4 of Jojo's Bizarre Adventure:
Diamond is Unbreakable, but it only got 58 supporters.
