What are your relationships with the Joestar crew? Any au :3
For the Sapphire Heartverse au (the main storyline), I'm a bad guy! I work under Dio alongside Vanilla (who I end up marrying and having a son with!) I guess the relationship with the Joestars is kind of strange. Considering in the story, Vanilla and I both have to take care of Jonathan's head and keep him alive. So, I'm considered a family friend to Jonathan
The only other time I actually have a conversation with a Joestar would be in Sapphire Heartverse 3: Pillars of Darkness. In which, I talk to Joseph, who learned some kind of magic to make him temporarily younger. (Only reason I did this was because I'm planning some drawings that will have to involve Youngseph specifically, and I want it to be a fandom thing, and tie into the Sapphire Heartverse)
So, it's pretty strange! Some might even say it's bizarre-
But yeah, uh... Joseph teaches Ramón hamon after the main villain (another oc) nullifies all the stand user's abilities. So it seems that Joseph and Jonathan don't have any problems with the Muscadine family
