A Killer lurks in town


Out of the hospital, Rohan draws Koichi into helping with his research. The pair discovers a ghostly alley inhabited by Reimi Sugimoto, the victim of an unknown serial murderer over a decade prior, and her dog Arnold. She begs Koichi and Rohan to find her killer, who continues to prey on the population of Morioh, and Rohan accepts her request. Rohan and Koichi also escape the malicious spirits of the alley who drag away anyone who looks behind their back into an unknown place.

Yoshikage Kira is introduced, speaking as though on a date to the severed hand of a woman.

Meanwhile, Josuke, who is nearly ruined, alongside Okuyasu, meet a child called Shigekiyo Yangu who likes to be called "Shigechi." Shigekiyo's hive-like Stand, Harvest, enables him to gather small items from the whole town. Striking a deal together, they accomplish several schemes in order to gather money, but the gains make Shigechi greedy.

When the trio gets rich thanks to a winning lottery ticket, Shigechi steals the paycheck. After a chase through the streets and roofs of Morioh, Shigechi manages to corner Josuke and Okuyasu by injecting alcohol directing in their bloodstream. However, Okuyasu uses The Hand to teleport the paycheck into his hand, and Josuke tears it apart and throws the pieces into the wind. Shigechi sends Harvest after the pieces but is defenseless when Okuyasu punches him. The trio reconciles afterward. One day Yoshikage Kira enjoys a picnic with his girlfriend, a severed hand hidden inside a sandwich bag. Coincidentally Shigechi swaps bags with Kira by accident.

Kira leaves before Jotaro and Koichi learn his identity. Jotaro has difficulty attacking the bomb and is incapacitated while trying to protect Koichi from an explosion.

Koichi calls Josuke for help and Stand evolves into Echoes ACT3. ACT3 can increase an object's weight and it immobilizes Sheer Heart Attack, obliging Kira to come back and fight Koichi. Although he easily defeats the boy and almost kills him, Jotaro intervenes and pummels Kira before fainting.

Josuke and Okuyasu arrive and rescue their companions. They then surround Kira, who cuts his hand and sics Sheer Heart Attack on them.

Later, Rohan is challenged in a series of games of rock-paper-scissors by Ken Oyanagi. Rohan refuses but Ken harasses him into accepting a game. It is then that the mangaka discovers that the boy is the user of the new Stand Boy II Man, which can steal someone's power if he wins three rounds of rock-paper-scissors.

On the verge of losing, Rohan manages to use Shizuka's power to make things invisible to save himself, transforming Ken's "scissors" into "rock" and wins a first time. He then completely defeats Ken in their game of rock-paper-scissors fair and square.

Mikataka has difficulties maintaining the masquerade and Rohan eventually suspects Josuke of cheating. Their game is interrupted anyway when Rohan accidentally sets his home on fire.

Josuke and Mikitaka finally get away scot-free while Rohan's house is burned down because of a magnifying glass.

The Hunt restarts
Still sour about their game, Rohan meets Josuke again on a bus. Inside of a tunnel, he spots in the walls what appears to be a room in which a man bends over and severs the hand of an unconscious woman. Unable to convince Josuke of what he's seen, Rohan investigates the tunnel alone. Is it then that the Stand Highway Star traps Rohan in the room and absorbs his life-force to heal its user. Josuke intervenes and decides to go look for the user. While Highway Star relentlessly pursues Josuke who rides a motorcycle across the streets of Morioh, the student calls Koichi who discovers the location of the enemy. Josuke manages to reach the user, Yuya Fungami, and beats him down.

Meanwhile at the Kawajiri's, Shinobu Kawajiri accidentally kills the cat Tama. However, Kira finds it resurrected as a plant using the Stand Stray Cat. Kira and Stray Cat fight briefly and Kira has difficulties against the air-controlling Stand. However, it is soon distracted and Kira transports it in the house's attic.

One day, Josuke, Okuyasu, and Mikitaka meet Toyohiro Kanedaichi, a man living on a transmission tower. Toyohiro tricks Josuke into entering the tower which is his Stand Super Fly. The sole remaining person inside Super Fly cannot escape it, and Josuke and Mikitaka work together into throwing Toyohiro back in it.

Toyohiro's acrobatics and knowledge of the subtleties of his Stand give him the advantage inside the tower, and Mikitaka is wounded while Josuke almost slips from the top of the tower. However, Crazy Diamond returns the energy shot at Josuke into Toyohiro and the latter yields. Toyohiro then reveals that Koichi has been taken down by another of Yoshihiro's assassins.

Warned by Toyohiro about a new enemy Stand User in town, Josuke and Yuya work together to find the enemy Stand user, revealed as Terunosuke Miyamoto, the new user of the Stand Enigma. Enigma traps people into paper once Terunosuke can guess what ticks they have when they are afraid. He uses Tomoko to bait Josuke and manages to trap the student inside a sheet. However, Yuya intervenes and manages to save Josuke from being shredded. Subsequently, Josuke defeats Terunosuke by fusing him with a book, freeing Koichi and his mother Tomoko.

In the meantime, Kira finally snaps and gives in to his urges, murdering a man and a woman inside their home. However, Kira notices that Hayato Kawajiri has witnessed him. When Kira confronts Hayato about this, Hayato tells Kira that he has numerous proofs that he isn't his true father and tries to intimidate the serial-killer into leaving his family unharmed. As Kira must deal with Hayato, Rohan notices a photograph of Hayato filming his father, but his investigation is interrupted when he welcomes Masazo Kinoto, the architect supposed to repair his house. Masazo hates having his back being seen and Rohan cannot resist the temptation to look.

Unfortunately, he inherits the Stand Cheap Trick which attaches itself to Rohan's back and will kill him if anyone sees it. Cheap Trick is invisible to everyone but Rohan, is invulnerable, and relentlessly tries to get people to see Rohan's back. With Koichi's help, Rohan uses the malicious spirits of the ghost alley to get rid of it.

Showdown against Yoshikage Kira


Kira, after having killed Hayato in anger, finds himself forced to flee Morioh. He refuses to yield and is pierced by the Arrow, which grants him the new ability Bites the Dust.

Moreover, the death will still happen in the next time loop. During the time loops, Rohan, Jotaro, Josuke, Okuyasu and Koichi die. Cornered, Hayato tries to assassinate Kira by using Stray Cat but the attempt fails.

However, Hayato manages to trick Kira into revealing his own name publicly and is heard by Josuke whom Hayato has called. Forced to retract Bites the Dust to defend himself, Kira cancels everyone's death and is cornered by Josuke and Okuyasu. Unfortunately, he uses Stray Cats invisible air bubbles as bombs and blows a hole in Okuyasu's stomach. A fight ensues between Josuke and Kira. Okuyasu is healed but remains unconscious. Josuke and Hayato retreat into a house, where Kira's air bubbles prove uncannily precise in tracking him. Josuke uncovers Yoshihiro and kills him for good using Kira's bubbles. Although he manages to wound Kira with a projectile, Josuke is hit by one of the bombs.

Josuke, heavily wounded, confronts his foe outside. The two Stand User clash again, and while Killer Queen is weaker physically, Stray Cat's bubbles block Crazy Diamond's punches. Josuke is saved at the last moment when Okuyasu wakes up and teleports Stray Cat away from Killer Queen.

Trivia

 * Unlike most of the other parts which had the characters travel long distances, Diamond is Unbreakable entirely takes place in the fictional setting of Morioh, exploring the small town in detail.
 * Leaving the Tarot and Egyptian mythology in Part 3, Part 4 primarily references popular (rock) music in its names.
 * Araki states that it is possible that JoJo's Bizarre Adventure could have ended with Part 3 since the resurrection of DIO was the last plot element of precedent.
 * This part is notable for having one of the most drastic changes in art style as it progressed. At its inception, it took on the muscular, inspired look that was present in the previous three parts. Around the middle of the part, the various characters took on a more youthful appearance, particularly in the case of Josuke and Koichi. By the end of Diamond is Unbreakable, the manga adopted the glamorous art style in which characters go from very muscular to athletic that would define the visual presentation of Vento Aureo and Stone Ocean.
