JoJo’s Bizarre Adventure isn’t the best-known manga property in the west, so perhaps you’d like a primer on its plot ahead of JoJo’s Bizarre Adventure All Star Battle? This trailer offers just that.
It’s eight minutes long and covers several arcs of the original manga, and it’s worthwhile staying tuned as things go from “a bit odd” to “I can’t remember who anyone is but I suddenly think my wardrobe needs a reboot”.
If your eyes start to glaze over, the Wikipedia article also has a decent summary.
JoJo’s Bizarre Adventure All Star Battle is out now in Europe and arrives in North America on April 29, for PlayStation 3.
