As its name suggests, Rolling Stones takes on the appearance of a spherical rock. It will predict the nearby death of someone in the vicinity and automatically follow them; once touched, it will kill the victim in a peaceful way.
Rolling Stones usually manifests as a spherical rock crudely carved with the character, kyō (凶, meaning "ominous", "misfortune", or "bad luck"). When Rolling Stones is touched by someone who isn't a target, sentences such as Please kill me (オレヲ殺シテクレ, Ore wo koroshite kure) can form on their skin.
When Rolling Stones targets a victim, it'll gradually change appearance to resemble them in their dying moments; even the dust remains of Rolling Stones molds itself in the image of the victim.
It is visible to ordinary humans, as an eyewitness reported seeing a woman holding it as she jumped down a building to her death.
Rolling Stones is an automatic Stand, as Scolippi can neither control nor stop it. It isn't actually malevolent as it shows a target their fated death, but the dubious mercy of instantly euthanizing them still makes it very dangerous.
Homing to Dying Target
Rolling Stones spots a target fated to die soon and then begins to automatically stalk it. Rolling Stones follows a chosen person whose death is close, appearing and disappearing or even moving by itself until it touches the target. In truth, it can enter the ground and walls to move unnoticed.
As it follows the target, Rolling Stones gradually breaks down until the form of the target appears on it. More precisely, it shows a presentation of the target dying, exposing how they are fated to die, regardless of how close or far away the date of death is. When the target touches the stone, they will die, peacefully and without visible damage, as to "spare" them the pain.
Although Scolippi theorizes that breaking Rolling Stones or changing its shape significantly may change the target's fate, it is ultimately revealed that even the dust will take the shape of the prediction. Thus it is impossible to change the fate predicted by Rolling Stones, but breaking it will still stop it from chasing people. Those close to Rolling Stones without being sculpted inside it are not fated to die. Mista exploits this to purposefully jump down a building and come out unscathed.
When someone not targeted by Rolling Stones touches it, several words or sentences such as Please kill me (オレヲ殺シテクレ, Ore wo koroshite kure) appear on their skin.
- Rolling Stone's ability is inspired by a famous quote from Renaissance artist Michelangelo about artistic inspiration, who claimed that every block of stone already had a statue inside it which the sculptor merely discovered.
