Diamond Is Unbreakable (ダイヤモンドは砕けない, Daiyamondo wa Kudakenai, formerly translated as Diamond Is Not Crash) is the fourth story arc of the Japanese manga series JoJo's Bizarre Adventure, written and illustrated by Hirohiko Araki. It was serialized in Weekly Shōnen Jump from 1992 to 1995. In its original publication, it was titled JoJo's Bizarre Adventure Part 4: Jōsuke Higashikata (ジョジョの奇妙な冒険 第4部 東方仗助, JoJo no Kimyō na Bōken Dai Yon Bu: Higashikata Jōsuke). The series was adapted as the third season of David Production's JoJo's Bizarre Adventure television anime series in April 2016.^[2]

Araki retroactively introduced the Bow and Arrow in this arc, which causes people pierced by it to develop Stand ability. Apparently this was used on DIO at the beginning of Part 3, which not only gave him a Stand but causes Stands to develop in the Joestar bloodline as well. As it is the fourth part of the series, the 174 chapters pick up where the third left off and are numbered 266 to 439, with the tankōbon volumes numbered 29 to 46 (the last three chapters are in volume 47). It was preceded by Stardust Crusaders and followed by Vento Aureo.

Plot

In 1999 in the town of Morioh (杜王町, Moriō-chō) located in S-City, M-Prefecture (M県S市, Emu-ken, Esu-shi), Josuke Higashikata (東方 仗助, Higashikata Jōsuke, the kanji 助 suke, can also be read as jo) is a popular boy in high school who becomes quick friends with one of his classmates, Koichi Hirose. When Josuke's nephew Jotaro Kujo (who's older than he is due to his father being his nephew's grandfather, hence the age difference) appears, Josuke is suddenly pulled into the world of the supernatural powers known as stands. One of DIO's henchmen has brought the Bow and Arrow to Morioh and someone has been using it on various people in the town creating Stand users—as discovered when one of them, the murderer Anjuro "Angelo" Katagiri, uses the power of his Stand Aqua Necklace to try and kill Josuke for interfering with his plans to rob a store and generally disturb the peace in Morioh earlier. Aqua Necklace manages to kill Josuke's grandfather, Ryohei Higashikata, in revenge for him being jailed by him. Josuke and Jotaro eventually capture him and, as a consequence of insulting Josuke's hair, ends up getting fused to the rock he was leaning on at the time, becoming a tourist attraction known as "Angelo Rock" in the process.

A few days later Josuke and his friend Koichi go to investigate a seemingly abandoned house, but Koichi is trapped and choked by a man later revealed to be Okuyasu Nijimura. Koichi was eventually struck by the arrow from the house, where he wouldn't have survived, as he does not have the same spiritual strength as the other victims of the arrow, hadn't Josuke intervened and healed him. They discover that the culprit of the shot is Keicho Nijimura, Okuyasu's brother. Their father - formerly DIO's lackey and injected with DIO's cells - has now turned into a monstrous creature with DIO's death. It is then revealed Keicho wants to create Stand users in the hopes that someone will be able to kill his monstrous father. Josuke manages to show the brothers that their father is still at least partially human inside and dissuades them from their activities. However they are attacked by the Stand Red Hot Chili Pepper, which kills Keicho and takes the Bow and Arrow. Okuyasu joins with Josuke, Jotaro, and Koichi to fight the Stand that killed his brother and eventually becomes close friends with Josuke. The group then continues to encounter other Stand users while looking for Red Hot Chili Pepper's user.

The plot begins to focus on Koichi when he is kidnapped by his classmate Yukako Yamagishi, also a Stand user, who is in love with him and is determined that he will love her back. He escapes from her and in the process his Stand evolves into a stronger form. The group then finally comes face-to-face with Akira Otoishi, Red Hot Chili Pepper's user. However, he proves hard for the group to defeat. Only when Joseph Joestar, the father Josuke never knew, arrives in Morioh are they finally able to defeat Akira. The Bow and Arrow are then taken into the Speedwagon Foundation's custody and all seems to be over for the moment.

A month later Koichi meets manga author Rohan Kishibe, whose Heaven's Door ability allows him to open up a person's face like a book and both read and rewrite their memories; Rohan finds himself drawn to the plucky Koichi, but does not get along with Josuke. Yukako and Rohan both become part of Josuke's group of Stand users along with others the group has encountered, such as Tamami Kobayashi, Toshikazu Hazamada, Mikitaka Hazekura, and Yuuya Fungami.

Soon afterwards, Koichi and Rohan discover a hidden alleyway in town that is not of their world. Once they enter, it is there they meet the ghost of a young girl named Reimi Sugimoto, Rohan's babysitter in his youth, who was murdered by a serial killer over a decade before. She begs Koichi and Rohan to find her killer, who has stayed in Morioh and is still preying on innocent people. This turns out to be Yoshikage Kira, a serial killer that kills women using his Stand Killer Queen to explode their bodies and keeps their hands as romantic mementos. When Josuke and Okuyasu's new friend, Shigekiyo "Shigechi" Yangu, discovers Kira's secret and is killed for it, they resolve to put an end to Kira's murders.

Jotaro and Koichi eventually fight Kira, but before he can be fully defeated, he flees and forces Aya Tsuji, the user of the Stand Cinderella, a Stand that can alter people's physical features, to change his face and kills her before she can tell Josuke what he now looks like. Shortly thereafter, the ghost of Kira's father uses a second Stand-creating Bow and Arrow to create an army of Stand users to protect his hiding son and go after members of Josuke's group. Rohan eventually suspects Kosaku Kawajiri is Kira's new identity and confirms it after reading Kawajiri's son Hayato's memories. However Rohan is killed instantly for his troubles by Killer Queen's new technique, "Bites the Dust", which Kira acquired after accidentally being stabbed with his father's Arrow. The ability plants a miniaturized Killer Queen on a person, with this person being Hayato Kawajiri, the son of the father he's impersonating, which not only kills anyone that tries to learn about Kira from them, it resets the time from an hour to a day, with the victim dying again as normal as soon as the original time of the explosion reoccurs. This continues until Kira finds out who the bomb killed. It also protects Hayato from harm, whether from the outside or self-inflicted.

When Rohan's death is repeated a second time, Josuke, Koichi, Okuyasu, and Jotaro were there to meet him. They see Hayato and figure out Kira is masquerading as his father, all of them dying as a result. The memory is then repeated again so Kira can learn who was killed, but this time Hayato tricks him into giving his own identity away before Rohan's death. Kira was then forced to remove the technique from Hayato to protect himself as he fights Josuke, resulting in an end to the time-loop and saving Rohan's life. With help from Josuke, Hayato, Okuyasu, and Koichi, Jotaro delivers a blow to Kira that propels him in front of an ambulance and he is run over. Kira is then shown as a ghost as his first victim, Reimi, informs him what happened. Kira attempts to attack Reimi once more, only to be torn apart by countless phantom hands, presumably of his other victims.

With Kira dead and the murders solved, Reimi and Arnold say their last goodbyes to Josuke, Rohan and the other Stand users of Morioh as the two spirits ascend to heaven. As Jotaro and Joseph prepare to leave Morioh, Josuke wishes them the best, but not before using Crazy Diamond to snatch Joseph's wallet, distressing his father.

Later on she gives up forcing him to like her, but uses the power of Aya Tsuji's Stand, which causes her to be unusually attractive to Koichi, resulting a side-story and by the end an actual relationship between them. At one point, she stood too close to the edge of a cliff which crumbles, causing her to fall into the ocean above several sharp rocks. Koichi saves her with the use of Echoes Act 2, making the rocks bounce her back up to safety.

He has a tendency to get furious when someone enters his kitchen without permission out of the fear that the person will defile it, and therefore will punish them by making them clean the entire kitchen. His Stand Pearl Jam (パール・ジャム, Pāru Jamu, renamed "Pole Jam" in Crunchyroll Anime) heals people by intrinsically telling Tonio what their injuries are and he prepares a dish for them that they will undoubtedly find delicious. In the side story Thus Spoke Rohan Kishibe ~Episode 6: The Poaching Reef~, Tonio admits to Rohan that he came to Japan to seek out a particular type of abalone native to Morioh so he may use it in his cooking to cure his childhood sweetheart of a massive brain tumor that has left her incapacitated, and he believes only this special abalone combined with Pearl Jam can cure her. He intends to poach the abalone, claiming he has discovered that there is a tradition in Morioh of poaching the abalone on a particular night when they cannot tell up from down and swim about, and takes Rohan with him for help. But the "tradition" is actually a trap to execute would-be poachers when the abalone stick to them and drag them beneath the surface, and Tonio is dragged under when three abalone stick to him. Rohan is only able to save him by using Heaven's Door on a nearby octopus, the abalone's natural predator according to Rohan's research, and later at the restaurant, Rohan watches on as Tonio and his lover enjoy a moment together, the woman standing for the first time in years.

Voiced by: Kishō Taniyama (Anime), Daichi Kanbara (EoH)

He has the strange ability Earth Wind and Fire (アース・ウインド・アンド・ファイヤー, Āsu Uindo Ando Faiyā, renamed "Terra Ventus" in All Star Battle) to shape-shift into any physical form he chooses at almost any size. While it could possibly just be Stand power, this is contradicted by the fact that whenever exposed to a siren or a similar sound Mikitaka will suffer from a painful rash until the sound stops. His mother is briefly shown and says his alien claim is just an act, however seeing as he did not see Josuke's Stand when he tried to attack him, it can be assumed that he is not a Stand user. All of this causes mystery surrounding his character.

Should another person enter Super Fly's range, Kanedaichi can escape its clutches. Also, it cannot be damaged and any damage done to it will be reversed out back to the person who inflicted it. Kanedaichi uses this to attack people, by cutting and hammering in nails into the tower to allow them to ricochet out.

This peculiarity intrigues Rohan who tricks Masazo to get a look at his back, causing the stand to kill Masazo and attach itself to Rohan creating a side-story. The fact, that the user dies when using his stand makes it clear, that Masazo was not an enemy trying to kill Rohan, especially since he showed fear before dying.

Voiced by: Toshiyuki Morikawa (Anime), Rikiya Koyama (ASB, EoH)

The main antagonist of the story, he is a serial killer who been murdering women for over 15 years. He longs for a simple life and doesn't wish to be bothered, shown by the fact that despite his many talents, both physical and intellectual, he purposely holds back so as to not draw attention to himself. He keeps a collection of his own fingernail clippings (sorted in jars by year, with the length of each recorded in a notebook) and has a fetish for the female hand, stemming from an erotic fascination with the hands of the Mona Lisa as a young boy. This results in his murdering women in order to acquire their (severed) hands as "girlfriends"--when one "girlfriend" begins to decay, he goes off in search of a replacement. Originally, Kira murdered his victims by stabbing them so viciously they were left with horrific back wounds. However his Stand Killer Queen (キラークイーン, Kirā Kuīn, renamed "Deadly Queen" in All Star Battle) eventually awoke from his desire to leave no evidence behind—hence its ability to completely disintegrate his victims by explosion. He now lets Killer Queen annihilate his victims (except for their hands), letting everyone else think that the victims have simply gone missing.

After being found out by, and battling Jotaro and Koichi, Kira flees and forces Aya Tsuji to use her Stand and change his face. He kills her and then escapes before they can catch up. His new identity was that of Kosaku Kawajiri and in order to not be discovered, he fights the urge and refrains from killing. However, Kawajiri's son Hayato realizes his father is acting strange and follows him trying to figure out why. Eventually Kira admits to him who he is and seemingly kills Hayato, but Kira soon after learns Killer Queen No. 3 and uses it on Hayato, implying that it brought him back to life. He uses Hayato as a weapon to kill Josuke's group and actually does, however because of some restrictions on the ability, Hayato is able to trick him into ending the technique and giving away his new identity, the final fight ensues. He is killed when Jotaro knocks him into the path of an ambulance, and is later shown as a ghost, at the mercy of the ghosts of his "girlfriend" hands.

Killer Queen's Bomb No. 1 turns anything it touches into a bomb, while Bomb No. 2 titled Sheer Heart Attack (シアーハートアタック, Shiā Hāto Atakku) is a small indestructible fully automated tank-treaded bomb that attacks the object with the highest temperature in the area. He acquires Bomb No. 3 titled Bite the Dust (バイツァ・ダスト, Baitsa Dasuto) towards the end of the arc when he is accidentally stabbed with the Bow and Arrow. This ability plants a miniaturized Killer Queen on a person and kills anyone that tries to learn info about Kira from them, as well as protects that person for 24 hours. When they learn Kira's identity, or anyone else inquires of information about Kira from them, Killer Queen enters their field of vision, then enters their eye and explodes. The period in which the victim learns his identity and the bomb explodes is repeated in-loop until Kira learns who the bomb killed. The bomb will also reset the time if anyone else is killed within the explosion, and if no one else is killed in the explosion, time will continue without any reset. He must remove the technique to use Killer Queen in any other form.

Kira also stars in Araki's three chapter spin-off story Dead Man's Questions (デッドマンズQ, Deddomanzu Kyū), which was published in the magazine Allman in 1999 and follows him as a ghost after his death. He reappears in the Jorge Joestar novel, again as a ghost where he ultimately suffers a final humiliation when Killer Queen, disgusted by him, leaves and becomes the Stand of Ultimate Cars.

Takuma Hasumi (蓮見 琢馬, Hasumi Takuma)

Takuma is a teenage boy who was abandoned by his father at a temple after his mother died in childbirth. He has an eidetic memory, able to remember any manner of information permanently, but it cannot be used to his advantage and haunts him. For example, he can never forget the pain of being struck by a car, and this causes him to scratch at his arms until they are red and scarred. His Stand The Book (The Book（ザ・ブック）, Za Bukku) helps him recall other certain situations at will. After discovering it was actually his father who caused the death of his mother as a result of abuse, he sought out his father by killing a former lover of his to track him down personally. During this time, he meets Chiho Futaba, unaware that she is his half-sister. The strange events of this woman's death causes Josuke, Koichi, and Okuyasu to get involved, and in a confrontation with Josuke, Takuma kills himself to finally relieve himself of the pain he has been suffering from.

Chiho is a young girl who when she was 12 was so upset by her father abusing her mother that she ran away from her home in Morioh to S-City, but returned when she realized she had nowhere else to live.

It is along this way that she meets Takuma and befriends him, unaware that they are related. She then discovers he is her half-brother and in a rage attacks her own father with a knife, killing him. After Takuma's death, she is then sent away from Morioh.

Father to both Chiho and Takuma, and once known as Teruhiko Ogami (大神 照彦, Ōgami Teruhiko), he is a successful architect who was pierced by the Arrow while in Europe and developed his Stand Memory of Jet (メモリー・オブ・ジェット（黒い琥珀の記憶）, Memorī Obu Jetto), which traps a person in a particular area forever. He became so successful as an architect because he would create houses that require less materials than legally allowed, such that they would collapse in the event of an earthquake, and pocketed the extra money. His former lover Hanae Orikasa learned of this and warned then the man's girlfriend Akari Hirai, who confronted Teruhiko, but he trapped her in an alley using Memory of Jet's abilities. From there, he tried to kill her, but she was pregnant with Takuma Hasumi at the time, so he spared her.
