Hol Horse's Mission
In Cairo, Egypt, March 1999, an elderly woman asks a man with three watches, Hol Horse, to find her missing parrot. The woman is the mother of an animal trainer who notably owned Pet Shop but had been killed by DIO. Because the parrot was trained alongside Pet Shop, there is the possibility that it is a Stand User and that the Speedwagon Foundation is trying to eliminate it. Hol Horse accepts the old woman's request out of kindness. Hol Horse then heads to a hideout to find an old comrade of his, Mariah, and they discuss the psychological scars DIO has left in them. Hol Horse accidentally makes Mariah angry and she uses her Stand Bastet to attack him. Hol Horse gets stuck on some pipes and is nearly impaled by several swords. However, Hol Horse survives and he meets Boingo, with whom he teams up again to find the parrot. Using Tohth's power of prediction to divine their path, Hol Horse and Boingo see that they must go to Morioh, Japan.

The Duo Arrives in Morioh
In Morioh, a young girl named Ryoko pays her respects to Noriaki Kakyoin's grave. It is revealed that she is Kakyoin's cousin and that she too was approached by DIO ten years ago. On her way back to university, she finds Tohth on the ground. Reading it out of curiosity, she reads DIO's name in the page and realizes that it must have some importance. She takes and hides the book in her bag just as Hol Horse walks by her. Hol Horse has just lost Boingo's trace and he tries to ask the locals for their assistance without success. Suddenly, a car driven by a possessed man surges towards Hol Horse. Hol Horse suddenly finds himself paralyzed by his old fear of DIO and is only saved by Josuke Higashikata's intervention. However, Josuke has seen Hol Horse's Stand Emperor. Considering him suspicious, Josuke challenges Hol Horse.

Josuke and Hol Horse mock each other's sense of fashion when the possessed driver almost collides into Hol Horse from behind. Josuke protects Hol Horse again by punching the driver in the face and then healing the man's wounds. Josuke also heals the injuries of everyone wounded from the car accident. However, the pedestrians assume Josuke and Hol Horse caused the accident because of their appearances. While Josuke intimidates them, Hol Horse takes the opportunity to run away. Hol Horse thinks to himself about everything that happened and wonders about the Stand User that possessed the driver. Suddenly, Josuke appears behind him as he didn't want to be at the accident scene when the police shows up. Josuke stops Hol Horse from running away with his Stand, forcing Hol Horse to introduce himself. From afar, a parrot watches them with its Stand.

Meanwhile, Ryoko thinks about the book she picked up and wonders whether it will have any clues about Noriaki's death when new pages suddenly appear. An elderly lady kindly asks a thug to move his car since he's parked in the middle of the road, but he tosses his phone at her in response. Ryoko intervenes and says the thug should park somewhere else. At first the thug assumes Ryoko is one of Yuya's girlfriends, but then insults Ryoko’s dangling hair claiming Yuya wouldn't date someone like that. Josuke, who was behind Ryoko, assumes the thug was insulting his hairstyle instead. Josuke rapidly punches away the thug’s car with Crazy Diamond and reshapes the car's roof into a cage. Ryoko is surprised to see that everything the book predicted in its new pages came true.

Ryoko and Josuke's Conflict
Ryohei talks to Boingo at Budogaoka Police Station and learns about Boingo's predicament. Boingo had dropped Tohth somewhere and got lost while searching for it. Ryohei asks his co-worker, Karaiya, to take Boingo back to his hotel. Just then, they receive a police report about Inspector Hiraoka's car going out of control and crashing into a shop. Ryohei hears that a student was at the scene, whose description sounds a lot like Josuke. He rushes out of the station on his bicycle, hoping Josuke hasn't gotten into trouble again. Meanwhile, Josuke is angry at Ryoko for indirectly insulting his hair. Hol Horse gets in between them and calms Josuke down. Josuke and Hol Horse explain to Ryoko how Hol Horse is looking for Boingo and asks whether she has seen him. Hearing about Boingo's comic book, Ryoko realizes it must be the book she picked up but she keeps it hidden, wanting to keep it for herself until she finds out the cause of Noriaki's death. She tells Hol Horse to go ask at the neighborhood police station nearby.

After Hol Horse leaves, Ryoko reads new pages in Tohth which predict that Ryoko will slap Josuke in the face to learn the first hint toward Noriaki's death. Josuke suddenly grabs her and tells her to leave because he doesn't want his grandpa finding him. The two end up arguing over Ryoko's attitude and each other's hairstyles, leading Ryoko to eventually slap Josuke for insulting her cousin, as Noriaki was who she based her hairstyle on. However, Josuke smiles in response, asking if she feels relieved now. Hol Horse enters the police station only to learn that the possessed driver from the car crash is actually a police inspector. Inspector Hiraoka insists to his co-worker that he's innocent and the car crash wasn't his fault, as his co-worker tries calming him down. Hol Horse decides he should leave before the inspector sees him but then suddenly sees the parrot and its Stand. The parrot activates its ability and punched cards enter Hol Horse's body. He starts hearing DIO's voice again and becomes unable to control himself, forced to point Emperor at the back of Inspector Hiraoka's head from behind, just like he was about to shoot DIO ten years ago.

Hol Horse's Dilemma
Hol Horse continues hearing DIO's voice, realizing that the parrot is making him reenact his own events from when he heard DIO's words ten years ago. Suddenly, he notices two sparkling cufflinks on Hiraoka's sleeve when a pedestrian signal behind him flashes green. The green light and the sparkling cufflinks evokes a memory of Hol Horse seeing Hierophant Green's Emerald Splash technique in the skies of Cairo when Noriaki was fighting DIO. At the time, a bandaged Hol Horse and Boingo were running away on the street when they saw the numerous Emerald Splashes above them.

Focusing on the different memory allows Hol Horse to escape from the Stand's grip and he pukes out the Stand's punched cards. Hol Horse leaves the police station, surmising that someone must have stolen the parrot to make use of its power. Just then, a group of four female chefs from a pastry shop walk out of their store, each holding knives. One of them slashes the neck of an elderly woman who had just arrived to pick up her order. Walking as if they're in a trance, the women all exclaim that they're offering everyone's blood to DIO.

One of the women stabs Hol Horse in his side. He realizes his dilemma as he's up against an enemy he can't simply shoot with Emperor. Meanwhile, a mysterious figure watches the battle with the parrot perched on their arm. Intrigued by the discovery of other Stand users being in the town, they declare that they'll show the real power of the parrot, revealing its name to be Petsounds.
