SO Chapter 1

Stone Ocean, Part 1 (その①), originally in the WSJ release, is the first chapter of Stone Ocean and the five hundred ninety-fifth chapter of the JoJo's Bizarre Adventure manga.

Summary
It is the 28th of October, 5:35 P.M. Standing in a rainstorm, a young woman beside a car is seen staring at the corpse of a man. She is shown to have a tattoo of a butterfly on her left arm.

In a holding room, various female prisoners are seen in different cells. One particular prisoner, a woman with braided hair, is annoyed by the noise of another prisoner. This prisoner is revealed to be Jolyne, who is banging her head against her cot out of embarrassment for getting caught masturbating by a guard. Jolyne says she will never masturbate again, and would wager a large sum of money on it with the others in the room. One of the other prisoners responds mockingly, asking how anyone could be held accountable in said bet. Jolyne replies, "If I were to say that I could tell... by the join of your left ring finger... would you believe me?" Just before Jolyne and the woman with braided hair are transferred to prison, Jolyne asks the woman "If I said I was 'framed'... would you believe me?"

Jolyne is informed by her lawyer that she has been arranged to go to Green Dolphin Street Prison to receive her punishment for her crime. The lawyer also brought essentials for Jolyne's use, with a shiny amulet from her father among them. After opening the amulet, Jolyne cuts her finger with a chipped stone stored inside the amulet. Jolyne states that her father had never been there for her, and that it would be useless to contact him. On a photo inside the amulet, an image of her father wearing a cap and white clothing along with her mother is shown. She throws the amulet away and it drops into a drain.

Her full name is revealed by her lawyer to be Jolyne Cujoh.

Later, on the 6th of November 2011, Jolyne talks with the same woman with braided hair, in a vehicle heading to Green Dolphin Street Prison. She introduces herself as Ermes Costello, and informs Jolyne that she will need to have money in the prison. Jolyne manages to guess where Ermes is hiding her own money: a surgically added hole in her left breast.

After Jolyne exits the vehicle, she hears a conversation, although no one is speaking nearby. As she is listening to the conversation, she discovers a string coming out of her injured finger. The string leads back to the truck she was on, and the conversation she was hearing is revealed to be Ermes being threatened by the guards. Using the string, Jolyne manages to stop a guard from striking Ermes by cutting the guard's ear off, and steals some money with the same string.
