Irene

Irene is the alternate universe version of Jolyne Cujoh in Part VI: Stone Ocean

Synopsis
She appears to be somewhat carefree and friendly, even giving rides to multiple random strangers without second thought. She looks almost exactly like her original self, aside from her long hair and a sweater covered in heart shaped holes.

History
After the universe is reset due to Made in Heaven, Emporio Alnino defeats Pucci and is transported to a random gas station. There he meets several alternate universe versions of his friends, including Irene and her apparent boyfriend, Annakiss. Soon after Emporio misses the bus, Annakiss and Irene offer to give him a ride, ensuring him that they aren't bad people. Irene tells Emporio that they were on their way to meet with Irene's father in order to ask for his approval of her and Annakiss' marriage. As they talk, the rain starts up and Irene takes off her jacket and wraps it around Emporio. Emporio notices the Joestar Birthmark on Irene's shoulder and tells her his name. The group drives off, but not before Irene tells Annakiss to stop the car to give a ride to what appears to be an Alternate Universe Weather Report walking on the side of the road.

Trivia

 * Her Name is a reference to one of Araki's first work, Gorgeous Irene.
 * In an interview, Araki states there isn't any deep meaning or relationship between the two Irenes, and he was simply having a good time writing the manga at the time.
