Episode 13 (OVA)

DIO's World: Farewell, My Friends (DIOの世界 -さらば友よ-) is the thirteenth and final episode of the JoJo's Bizarre Adventure OVA. It adapts Chapter 256 through Chapter 265 of the manga.

Summary
Jotaro and DIO. "The World" seems invincible as Jotaro is struck time and time again with murderous blows. If Jotaro cannot discover the secret of DIO's Stand and find some way to counter it, the Joestar line will come to an abrupt and bloody end.

Manga/Anime Differences

 * Unlike the manga and anime, where Dio throws to Jotaro road roller, in the OVA he throws an oil tanker.
 * Rather than taking Dio's hiding spot underneath the sewer manhole cover and waiting for the vampire there, Jotaro steps on the manhole cover before Dio can move it aside so he can crawl inside.
