Reimi Sugimoto

Reimi appears as a teenage girl in a short dress and hairband. As a ghost she no longer ages, retaining the state in which she died. Her friendly manner can make her seem like an ordinary local girl until she reveals what happened to her.

She is warm and caring, but determined that Morioh should no longer be a place where Kira can kill without consequence. Her wish is not simply personal revenge: she wants other families to be spared the fate of her own.

Reimi's supernatural nature is that of a ghost, not a named Stand. Ordinary people cannot normally see or hear her, while Stand users can interact with her. She can become intangible, and Heaven's Door can affect her.

She remains around the hidden alley with Arnold and knows its danger: someone who looks behind themselves at the wrong point can be taken away by the hands of its spirits. This rule belongs to the alley; it should not be confused with a combat Stand controlled by Reimi.

On August 13, 1983, Reimi is looking after four-year-old Rohan while his parents are away. Kira enters the house and kills her parents and Arnold. Reimi helps Rohan escape through a window before she is killed herself.

Her spirit remains in Morioh, waiting for someone who can hear her story and help stop the murderer. Years later, when Rohan returns to town, he and Koichi enter the alley and meet her. She explains that the killer is still active and asks them to investigate.

Reimi becomes a point of contact for the Stand users searching for Kira. She sees Shigekiyo Yangu's soul after his murder and confirms that he has died, giving the group another reason to act.

She also notices the connection between Hayato Kawajiri and the man appearing as Kosaku Kawajiri in Rohan's photographs. That observation helps move the investigation toward Kira's stolen identity.

After Kira dies, his ghost arrives in the alley. Reimi confronts him, and Arnold forces him to look back toward the spirits that seize him. With the threat ended, Reimi and Arnold say goodbye to Morioh's Stand users and pass peacefully into the afterlife.

Her story links the town's long history of disappearances to the present investigation. Saving Rohan as a child and later helping him find the killer gives their reunion a meaning he does not initially remember.
