Jotaro Kujo/Personality and Relationships
Personality
He has a very tough exterior, and is even rather rough and delinquent, but he also is very dedicated, intense, and loyal. He is intelligent, but usually lets his (or Star Platinum's) fists do the talking with the enemy, even though he often has to rely on his wits to deal with stand users' attacks. Jotaro has a perpetual cooler-than-thou, slightly disinterested attitude, although he loves his mother and respects his grandfather. It is not that he is unaware of his own love and/or respect--rather, he thinks anyone can tell his emotions just by looking at him, and probably thinks further effort in portraying how he feels to be a waste of time. In the manga, he's constantly chased by adoring girls, whom he ignores or tries to drive away. He is the main target of Dio, who realizes that Jotaro is his greatest threat.
In part 6, he also shows his protective father side, often taking near fatal blows for Jolyne and throttling her out of harm's way. After he is "revived", Anasui, one of Jolyne's companions who is enthralled by her, asked Jotaro to approve of marrying her. Although he first acted deaf, Jotaro got the picture when he saw her lean against Anasui's chest. Not ready to see his daughter married off right away, he pulled his daughter into his arms, leaving Jolyne clueless to their interactions.
Jotaro is both fierce and gentle, and he shows these traits in various scenes, from the fight with N'Dour to the encounter with D'Arby. One shining example is how he spared Noriaki Kakyoin, instead of destroying him outright.
