Jotaro Kujo/Personality and Relationships

Stardust Crusaders
"I beat the crap out of more people than I have to. Some are still in the hospital. There’s plenty of teachers that got on my bad side and never came back to class. And, hey, I make it a policy not to pay if I don't like a meal. But even a guy like me can spot evil when he sees it!"

- Jotaro to Noriaki Kakyoin

Jotaro is introduced as a rough delinquent, but he has a gentle heart, and is loyal to those he likes. He is highly perceptive, intelligent and quick-witted while keeping a perpetually cool, slightly neutral or disinterested attitude.

Jotaro's most noticeable trait is his seemingly aloof nature. He is a quiet individual, often satisfied with expressing himself in short phrases. Araki has explained that 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 callous.

Jotaro is both fierce and gentle, showing these traits in various scenes, from the fight with N'Doul, to the encounter with the D'Arbys. One shining example is how he spared Noriaki Kakyoin instead of killing him outright - even putting his own life on the line just to save the young man from DIO's deadly slavery. Despite not being overt about displaying it, Jotaro loves his mother and respects his grandfather Joseph. Jotaro's impetus for going to Egypt is Holy's life being put in danger by DIO's Stand, and he flew into an uncharacteristic rage when the vampire desecrated the corpse of his grandfather, before apologizing to Joseph's spirit (who had previously warned Jotaro not to succumb to anger). During his journey to Egypt, Jotaro has attached himself to his companions, and through several small gestures expressed his friendship toward them, culminating with a hug with a departing Polnareff. Signs of him loosening up were also shown where he occasionally (but not often smiles) such as when the group make fun of ZZ and at one point even laughing alongside Kakyoin and Polnareff upon discovering the Sun's weakness in episode 18. Jotaro doesn't tolerate when one hurts women or children in a fight, even if they are evil, and will be especially violent toward the perpetrator, as seen against Steely Dan, whom he pummeled the most severely. Jotaro is still prone to violence, and doesn't hesitate from severely hurting his enemies, even if they are women.

Jotaro is an extremely cool individual, able to keep his composure in even the direst situations. The best example of his coolness would be against Daniel J. D'Arby, playing a dangerous game of poker during which he successfully bluffs the expert poker player into folding even if he didn't know what cards he had and wagered the souls of every companion and ally involved. Still, he is still mildly anxious when something unanticipated happens, but almost never goes as far as to lose his cool.

Moreover, Jotaro is blunt and foul-mouthed, having no problem being insolent toward his mother or any authority figure. The teenager favors witty one-liners, often ridiculing whoever is the target of his quips and offering absurd reasons for his feats, notably defeating DIO because he pissed him off. Whether Jotaro does take himself seriously or is just having fun when using his one-liners is left unanswered.

Jotaro is interested in a large range of subjects, such as sumo or the TV series Columbo, from which he claims to have acquired his deductive skills. Several hobbies indicate that he has an intellectual side, which would result in him becoming a marine biologist.

Jotaro is annoyed by the numerous adoring girls chasing him (both at his school and throughout his journey), whom he ignores or rudely drives away; particularly when they begin to fuss or bicker. However, he is hinted to have a soft spot (or is at least more tolerant) of children. When Anne accompanies them on his journey, he never yells at her and even protects her from enemy Stand Users, and also watches over her in a similar fashion to an older brother. When he takes an ice pop from a young boy, he tells the boy that he will buy him a new one.

Another interesting personality quirk of his seems to be an attachment to his clothing. when the female nurse at his school suggested cutting off parts of his pants, he refused. When his clothes were ripped from his fight with ZZ, he went so far as to pay for a uniform exactly like the one he had. When he first trades blows with DIO, he specifically points out how the fight tore a hole in his pants. He also has an attachment to his hat. This implies he is either stingy or has a particular sense of fashion; the fact that he pointed out the price of his pants after DIO tore a hole in it seems to imply the former.

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. Having matured, Jotaro isn't as foul-mouthed as he was, although he is still blunt and retains his annoyance towards girls making a fuss.

Although his aloofness is still present, it has diminished somewhat over the years; meeting Tomoko Higashikata whilst looking for Josuke shortly after her father is killed by Anjuro, he tolerates her sudden clinginess when she mistakes him for Joseph, and offers some consolation for her father's death. He also admits to Koichi that he was glad to meet him, albeit privately.

Stone Ocean
In Part 6, Jotaro displays his typical serious attitude, but this is also paired with a passionate paternal protectiveness for his daughter Jolyne, although his past neglect has worsened their relationship. Another instance of his diminished stoic attitude, he tells his daughter that he loves and cherishes her, which would motivate Jolyne throughout their adventure.

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.

During the final fight against Pucci, Jotaro's love for his family got the best of him, and he made the mistake of trying to both save Jolyne and kill Pucci, succeeding in neither and resulting in his death.

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 Cujoh: Jotaro's only child. 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 and being fully aware of his failures as a father. 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 their differences, they seem to get along fairly well, and can share a laugh or two once in awhile, and they were able to bond much more during their travel to Egypt in order to save Holly. When Joseph was infected by Steely Dan's Lovers, Jotaro allowed himself to be humiliated to protect Joseph from Steely Dan and repaid this enemy a thousand fold. They were able to work well together against Terence D'Arby purely through shared familial intuition, and when DIO desecrated Joseph's corpse, Jotaro was enraged enough to attack DIO head on despite knowing the serious risk. While he was annoyed about Joseph's affair with Josuke's mother, he still cared for his grandfather especially in his advanced age and decided to protect Josuke's mother in place of Joseph, showing his respect for Joseph's feelings. He also showed a rare smile when he saw Josuke and Joseph getting along.


 * Suzi Q: Although they've never communicated in the manga, the anime included a scene of Jotaro talking to his grandma on the phone. He respects her and assures her that there's nothing to worry about when Joseph couldn't talk to her. Suzi states that she was really happy to hear her grandson's voice after so long. She's heard that Jotaro became wild lately but she knows deep down that he's a sweet child who truly cares for his family.


 * Josuke Higashikata: The two have a somewhat mentor-protégé relationship, as Jotaro teaches Josuke various tactics. Although Josuke is younger than him, Jotaro is his nephew. When they first met, Josuke had assaulted Jotaro for mentioning his hair in a negative tone (despite Jotaro not intending to insult Josuke), but as the series progressed, the two became allies and have helped each other out a number of times against the various enemy Stands appearing in Morioh. Jotaro respects Josuke's ability and gentleness while being annoyed by his temper, and fully trusted him during their fight against Bug-Eaten.


 * 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.


 * Holy Kujo: Hollyjotaro.png 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 Holy 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.
 * Giorno Giovanna: While they have never formally met Jotaro investigated Giorno due to his connections to both Dio and the Joestar family.

Friends

 * Muhammad 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, and Midler.


 * Noriaki Kakyoin: Like with Avdol, Jotaro's first meeting with Kakyoin begins with combat. After defeating him, Jotaro takes Kakyoin to his house to remove DIO's flesh bud and release him from DIO's 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 he'd never be able to forget his ugly face.


 * Iggy: The relationship with Iggy and Jotaro is not as deep as with Kakyoin or Polnareff. However, Jotaro sees value in Iggy during the fight with N'Doul with his keen senses and powerful Stand. Iggy gives back Jotaro's lost hat, shortly earning his trust, until Jotaro realized that Iggy put coffee gum inside it. 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 with both the Joestars and DIO.

Enemies

 * Dio Brando: DIO viewed Jotaro as much of a threat as Jonathan was, if not more, going to extremes to outwit and ensure his death. While Jonathan was an opponent DIO respected, Jotaro was an opponent DIO feared. Jotaro on the other hand, despite being able to hide his emotions from other people, was secretly worried about his mother's failing health caused by her Stand and wanted to defeat DIO as quickly as possible, as her Stand was caused by DIO activating all the Stands in the Joestar bloodline at the same time. After DIO had apparently killed his grandfather Joseph right in front of him, Jotaro's hatred for DIO intensified to where, for the first time, Jotaro was visibly enraged and acted on anger. After a long and grueling fight with the vampire, Jotaro finally managed to outwit and kill DIO.
 * Enrico Pucci: Due to his status as Dio's top underling and the fact that he was trying to revive Dio, Jotaro greatly hated Pucci. Pucci in turn had an immense amount of hatred for Jotaro for killing Dio and attempted to murder him to avenge Dio and eventually succeeded.
 * Yoshikage Kira: The first time Jotaro would encounter Kira was near the Centipede shoe shop after Jotaro was heavily wounded by Sheer Heart Attack. Kira underestimated Jotaro due to the poor state he was in, only to get pummeled by Star Platinum for his trouble. Kira noted how dangerous Jotaro was and took the care to avoid confronting him again.
 * N'Doul: While the two were enemies Jotaro grew to respect N'Doul during their fight and buried him out of respect when he died.
 * Angelo: Due to his attempted murder of Josuke's mother and successful murder of his grandfather Angelo was definitely an enemy of Jotaro's. Jotaro assisted Josuke in defeating Angelo and even warned him about Angelo though pictures taken by Joseph's stand.
 * Johngalli A: While there is little interaction between the two, the fact he framed Jolyne for murder and attempted to kill her and him made them enemies.
