Jotaro Kujo/Personality and Relationships
Personality
Stardust Crusaders
Jotaro is introduced as rather rough and delinquent; but he is dedicated, fair, and loyal. He is highly perceptive, intelligent and quick-witted while keeping a perpetually cool, slightly neutral or disinterested attitude.
Two of Jotaro's schoolmates and the school nurse affirm that it seems impossible to best him in a fight. After gaining Star Platinum, this trait easily carries over to his encounters with new Stand users.
Jotaro loves his mother and respects his grandfather, although he may not be overt about displaying it. 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, making others tend to perceive Jotaro as a very aloof and callous person when he is in reality caring and reverent.
Jotaro is both fierce and gentle, and he shows these traits in various scenes, from the fight with N'Dour to the encounter with the D'Arbys. One shining example is how he spared Noriaki Kakyoin, instead of destroying him outright - even putting his own life on the line just to save Kakyoin from Dio's deadly slavery.
Jotaro is occasionally chased by adoring girls, including his classmates, whom he ignores or drives away; particularly when they begin to fuss or bicker.
He is Dio's main target, who acknowledges that Jotaro is his greatest threat. Apparently key to Jotaro's percieved chance of success in his final battle with Dio is the extent to which Dio is able to anger him.
Diamond Is Unbreakable
Jotaro is positioned during this story as a role model, leader or teacher. Koichi and Josuke comment that his company is calming to them, with respect to the consistent threat exerted by emerging Stand users.
Somewhat more sensitive; meeting Tomoko Higashikata while looking for Josuke shortly after her father is killed by Angelo, he tolerates her sudden clinginess while she mistakes him for Joseph; offering some basic consolation.
Stone Ocean
In Part VI, Jotaro shows a protective, fatherly side, often saving Jolyne from harm's way; and where possible receiving near-fatal blows for her.
After he is "revived", Anasui, one of Jolyne's companions who is enthralled by her, asks Jotaro to approve his proposal to marry. Reacting first as though he spoke meaninglessly, when Jotaro sees Jolyne lean against Anasui's chest, he pulls her into his arms, protectively; leaving Jolyne clueless as to their interaction.
Relationships
Jotaro's relationship with people is usually straight forward, due to his type of personality. He usually tends to keep his emotions to himself, as he believes people can read his emotions simply by observing him. Simply put, if anyone hasn't made him angry, he is usually satisfied with those around him.
Family
- Jolyne Kujo: Jotaro's one and only daughter. Jotaro, due to his many excursions, was an absentee father for much of Jolyne's childhood and well into her adolescence. As such, she grew to resent him though at times also craving his attention. His divorce only made matters worse, Jolyne practically disowning him and refusing to mention him until he visited her in prison. Jotaro, however, greatly cherished Jolyne, taking her safety above all else during Stone Ocean. Eventually they began to patch their relationship up, Jolyne finally understanding why Jotaro was absent constantly and what exactly he was fighting for.
- Joseph Joestar: Jotaro doesn't usually share his grandfather's humor, and the two have very different personalities. Despite that, they seem to get along quite well, and can share a laugh or two once in awhile. They were able to bond much more during their travel to Egypt in order to save Holly.
- Suzie Q Joestar: Their relationship is unknown, but with being in good terms with Joseph, it can be assumed Jotaro respects her as his grandmother.
- Josuke Higashikata: The two have a somewhat mutual relationship with Jotaro being his nephew, despite Josuke being younger than him. When they first met, Josuke had assaulted Jotaro for mentioning his hair, but as the series progressed the two have become allies and have helped each other out many times against the various enemy stands appearing in Morioh.
- Sadao Kujo: As a famous jazz musician, Sadao left his family to go on tour, and has never actually been seen in the series. It is unknown as to how long he has been gone, but there hasn't been any indication that Jotaro holds a grudge against him for this.
- Holly Kujo: As Jotaro's mother, she is one of the few women in the series that Jotaro actually cares for. In his childhood, Jotaro loved to play ball with her, but at his current age, his attitude has changed up to a point where he simply calls her annoying. Regardless, the two take care of each other, which may have been due to the fact that Jotaro's father had never had any time to visit his family, leaving Holly to take care of their son by herself. When she had fallen ill due to her Stand taking over her body, Jotaro had asked Joseph what they had to do to cure her. It was because of his concern for his mother's life that he set off to Egypt to annihilate DIO.
Friends
- Mohammed Avdol: His first initial meeting with Avdol was not very friendly, but after Jotaro begins to truly understand Star Platinum and Stands, they quickly become allies. During the journey Avdol takes the role of the mentor, providing the rest of the group information on enemies such as Gray Fly, Devo the Cursed and Midler.
- Noriaki Kakyoin: Like with Avdol, his first meeting with Kakyoin begins with combat. After defeating him, he takes him to his house to remove Dio's implant and release him from his control. Jotaro and Kakyoin later develop a strong friendship, discovering a mutual interest in sumo, and Kakyoin being one of the few people Jotaro smiles at.
- Jean Pierre Polnareff: After joining the group during their journey to Egypt, Polnareff gradually becomes good friends with everyone. At the end of part 3, Joseph and Polnareff along with Jotaro mourn for the loss of their friends. Before going their separate ways, the group embraces one last time; promising to meet each other again sometime in the future. Jotaro's only comment to Polnareff was a friendly insult, mentioning that'd he never be able to forget his ugly face.
- Iggy: The relationship with him and Jotaro is not as deep as Kakyoin or Polnareff however, Jotaro sees value in Iggy during the fight with N'Doul with his keen senses and powerful stand. Afterward, he gives back Jotaro's lost hat, earning his trust. Iggy, although not vocal about it, is a very prideful stand user, even believing that The Fool is stronger than Star Platinum.
- Koichi Hirose: After witnessing Koichi's bravery during the events in Morioh, particularly fighting Kira's Sheer Heart Attack while Jotaro was unconscious, he has come to respect and trust him a lot. This bond later influences Jotaro to choose him to investigate Giorno Giovanna for his bloodline link.
