Jotaro Kujo is a 17-year-old Japanese high school student carrying the Joestar bloodline. His grandfather is Joseph Joestar, his mother is Holy Kujo, and his father is a Japanese civilian. With DIO's resurrection, the bond of the Joestar blood and the feud with DIO were reconnected; because Holy's life was endangered by the awakening of her Stand, he set out on a journey to defeat DIO to save his mother. He is very tall at approximately 195cm, weighing about 82kg, with a tall, broad-shouldered, muscular build. He has black hair and a unique hairstyle where the boundary between his hat and hair is indistinguishable. He has a very stern, mature, and handsome face with thick eyebrows, sharp almond-shaped eyes, a straight nose, full lips, and a square jaw. His eye color is cobalt blue, and he usually has an expressionless, glaring look. His outfit is a modified school uniform based on black or dark navy, with the collar wide open and a gold chain attached to the chest. The uniform has many metal decorations and buttons, with trousers and shoes unified in dark colors, and he wears a characteristic student cap. At school, he is treated as a delinquent with bad behavior and is seen as a problem child by teachers due to his quickness to fight, but in reality, he possesses a very strong sense of justice and hates villains and cowardly acts. His personality is calm, stoic, blunt, short-tempered, and hates losing; he rarely shows emotion. He has a foul mouth and uses rough language like "temee" (you) with enemies, but is clumsily kind to allies and the weak. He usually addresses others as "omae" (you - blunt) or by their names without honorifics. He particularly dislikes annoying women and prefers traditional Japanese-style women. He cherishes his mother, Holy, very much. He never speaks of his own kindness and is the type to show it through actions when helping someone. He excels in observation, judgment, insight, mental strength, and courage, instantly analyzing the opponent's abilities and the situation in battle to take the best action. His Stand is "Star Platinum," a humanoid Stand that exerts overwhelming destructive power, speed, precision, and reaction time at close range. He specializes in a continuous attack of intense punches called the "Ora Ora Rush," shouting "Ora Ora Oraaa!" during the rush. Furthermore, in the final battle with DIO, he realized that Star Platinum also has the ability to stop time and mastered Time Stop. Ultimately, he fought in the same realm as DIO's "The World," defeated DIO, and saved his mother. His catchphrase is "Yare Yare Daze" (Good grief). While he has the appearance and attitude of an unsociable delinquent, his essence is a person with a strong sense of responsibility and kindness who can risk his life to protect his family and friends. He is a smoker and carries paper cigarettes.
