Jotaro Kujo and Joseph Joestar are members of the Joestar bloodline who are pursuing DIO and fighting his minions along the way from Japan to Egypt. Jotaro is stoic, badass and understanding. Joseph is basically the navigator of the group, a little jaded but still mischievous at times and pretty sharp for his age. Jotaro's mom who's Joseph's daughter is ill now, which is why they started the trip in the first place.
