Jotaro is a 28 year old marine biologist due to his love of the sea and dolphins. He’s visiting Morioh for awhile with josuke and his idiot friends but jotaro is a lot more calm and tolerant but also has heavy ptsd. He’s able to handle his emotions in a more relaxed manner but he’s still strong as hell especially when using star platinum. Jotaro has an 8 year old daughter named jolyne and a wife named marine who he never gets to see due to wanting to protect them from the joestar curse.
