Hol Horse's Mission
In Cairo, Egypt, March 1999, an elderly woman asks 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 and kick him 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.

One of the possessed chefs lunges at Hol Horse with a knife and slashes him. Meanwhile, Josuke asks why Ryoko doesn't go to Noriaki for help if something's troubling her and then awkwardly apologizes when Ryoko reveals that he passed away. Just then, Josuke hears a gunshot nearby, though Ryoko didn't hear it. Ryoko suddenly sees one of the possessed chefs charging toward them with a knife and kicks Josuke out of harm's way, fulfilling Tohth's next prediction. Struggling on the ground, Hol Horse yells out to Josuke, warning him that the women are being controlled. Trying to go as easy as he can, Josuke summons Crazy Diamond and rapidly punches all of the women at the same time. The nearby pedestrians wonder what just happened, as it looked like a storm swirled around Josuke. Josuke pretends that the whole thing was all a live performance. Meanwhile, the chefs get up and are no longer controlled. Their wounds are healed and everyone wonders what happened as they head back to work.

Josuke quickly runs to Hol Horse and heals him. Hol Horse reveals the parrot is a Stand user that was trained under the orders of a man named DIO. Josuke feels dumb realizing that even a bird could have a Stand. He had been sensitive about it because he thought he was the only one with it, as if it was some kind of sickness. Hol Horse also reveals that their problem isn't the parrot's Stand itself but the person who is hiding somewhere and manipulating the parrot. Since Hol Horse doesn't want to kill the bird and let its owner down, he asks Josuke for his help. Josuke agrees, feeling that it's nice to be relied on.

Ryoko was eavesdropping on their conversation, realizing that Hol Horse mentioned "DIO". Wanting to learn more about what he knows, Ryoko looks at the new pages in Tohth's book to see what she should do. The Stand mentions that she shouldn't just ask him directly because he'll play dumb. The best thing to do is look for a fuse waiting to be lit and then ignite it. After that, she'll finally reach the truth while everyone is screaming from the explosion.

Attack in the Subway Station
Sitting in a hotel room, Boingo thinks back to Tohth telling him that he has to part ways with the book for a while. Feeling nervous about not knowing the future anymore, Boingo recalls a memory of when his father sold the book for drinking money. However, Tohth reappeared by his side soon afterwards. Although DIO and his allies said Tohth was Boingo's Stand, Boingo feels that there really is a god named Tohth who chose him to be the keeper of the comic book. He wonders if Tohth left him to help him get over his fear of DIO. Deciding that he should go find the person who has his book, he takes a step to leave the hotel but ends up collapsing, too afraid to go alone.

Meanwhile, Hol Horse summarizes what they know about the parrot's Stand ability so far. He and Josuke wonder how they can do something about the bird before it attacks them first. They think they might be safe since they're in the subway and the bird probably won't come flying there. Josuke asks whether they should go look for Boingo but Hol Horse thinks having Boingo with them would weigh them down and just be putting him in danger since he can't fight. Josuke suggests that one of them should try acting as a decoy when they fight the parrot, when suddenly, a helicopter starts whirring behind them. Hol Horse starts trembling and wonders if he was that worried about hearing DIO's voice again. However, Josuke reveals that he also feels terrified all of a sudden and that something doesn't feel right. Just as the duo realize they're already under attack, they turn around and see each other's eyes are affected by Petsounds's Stand. They hadn't heard any voices, but they realize that it was the sound of the helicopter which triggered the ability.

Several civilians start running away from the illusionary helicopter. Josuke and Hol Horse witness a man getting shot by several bullets, but when they go up to him, they notice his wounds are all gone. Although the helicopter isn't actually there in the subway with them, everyone being controlled by the Stand is forced to reenact the scenario that the Stand is replaying from the parrot's memories. Hol Horse realizes that the scenario they're reenacting must be that they are citizens or rioters being shot down by a dictator's army in Egypt.

To make matters worse, a kid in front of them is shot by an arrow from a crossbow all of a sudden. Josuke realizes that it's a real arrow and not an illusion. He uses Crazy Diamond to heal the boy but then Josuke is also shot in the back. After Crazy Diamond takes out the arrow, Josuke furiously runs toward the mysterious enemy, planning to take him down. Hol Horse is surprised that Josuke could break free from Petsounds's ability. The enemy shoots arrows at Josuke again, with one of them nearly striking Josuke's forehead. However, his Stand manages to grab it in time before it could fully pierce him. Fear overwhelms Hol Horse as the military helicopter whirs above him, leading him to imagine his hand getting a hole shot through it. He eventually overcomes his fear and withstands the parrot's ability by realizing that the fear he feels now is nothing compared to what he felt back when he gave into DIO's will ten years ago.

Regaining his composure, Hol Horse fires two bullets with Emperor, blowing off the enemy's ear and a fragment of his crossbow. The enemy and Petsounds both flee but Josuke restores the fragment of the crossbow that broke off to track the enemy down. Hol Horse also manages to shoot Petsounds, blowing off a wing from the parrot. The crossbow wielder hides in the bushes, hoping Josuke will follow his blood trail so he could ambush him with an arrow. However, Josuke appears behind him while the man's crossbow is restored by Josuke's Stand. Josuke pummels him with several punches using his Stand and then takes the money from the man's wallet. He learns that the enemy is named Koji Kiyohara who is a university student. After Josuke ties Kiyohara to a tree, Ryohei arrives. Josuke tells his grandfather to arrest Kiyohara.

Searching for Tohth
Ryohei informs Josuke, Hol Horse, and Boingo about what happened to Kiyohara after he was taken to custody. They are planning to do a psychological evaluation on him because of videos they found in his home. Josuke and Hol Horse leave to go find Boingo's book for him, while Ryohei gives Boingo some motivation to search for the book on his own since he treasures it. Josuke eventually realizes that he saw Ryoko carrying the book earlier and goes to confront her. Ryoko tries to run away from him but is cornered into a dead end. With nowhere to run, she reveals that she can't give the book back yet because she is trying to find out the truth about what happened to her cousin. She tells Josuke about how Noriaki became a servant to DIO ten years ago and then mysteriously died.

Meanwhile, Kiyohara is sitting in his jail cell mumbling to himself in fear. When a police officer shines a flashlight at his cell, Kiyohara sees a memory of Kazuki Karaiya sitting beside him in a police car. Karaiya asks him how it felt to lose. When Kiyohara doesn't answer the question but instead asks who Karaiya is, Karaiya screams at him. Petsounds then appears behind Karaiya and activates its Stand ability on Kiyohara, causing him to shriek in his cell.

Trivia

 * Kouhei Kadono first mentioned the title of the manga in January 2013, stating that he is planning to work on it and hopes not to get carried away.
 * The word "Demonic" (悪霊的) in the title uses the same kanji as Jotaro's "Evil Spirit" (悪霊) from Part 3.
 * The scooters on the postcard illustrations included with volume 1 or the July 2022 issue of Ultra Jump appear to be scooters, possibly chosen as a subtle reference to DIO due to the shared names.
