Diamond Is Unbreakable

Plot

Characters

• Josuke Higashikata is the illegitimate son of Joseph Joestar. He is a freshman who lives in the town of Morioh with his mother and grandfather. His Stand is Crazy Diamond, which can not only punch rapidly, but also restore objects to their original state or rearrange their structure, allowing him to heal injuries, erase written documents, or revert complex structures to their raw components. However, Crazy Diamond has no effect when used on Josuke himself. Despite normally being kind and friendly, Josuke becomes especially enraged if anyone insults his pompadour hairstyle, which he adopted after a delinquent with the hairstyle saved him and his mother during a blizzard. This is demonstrated for the first time after he punches an upperclassman and incorrectly heals his face for insulting his hair.
• Koichi Hirose is Josuke's and Okuyasu's best friend and is also a freshman in high school, but appears as a short boy. His Stand is Echoes, which has three distinct "ACTs". ACT1 can create messages and attach them to a person by touching them, which results in the message repeatedly played in the victim's head, ACT2 has a similar ability but instead can attach onomatopoeia onto objects, causing the effect of the onomatopoeia to activate when touched, while ACT3 loses the former abilities and sacrifices its long range, it gains the ability "3-Freeze", which dramatically increases the weight of a target and thereby making it unable to move. Koichi gains access to each ACT as he grows throughout the story, ultimately gaining ACT3 in the first battle with Kira.
• Okuyasu Nijimura is one of the two Nijimura brothers who became friends with Josuke Higashikata and Koichi Hirose after encountering a Stand user who murdered his brother. His Stand is The Hand, which can erase whatever it swipes with its right hand and can even be used to erase space, drawing objects closer to Okuyasu. Though the ability is incredibly versatile and powerful, Okuyasu's subpar intelligence prevents him from using it to its fullest potential.
• Jotaro Kujo is an aspiring marine biologist who travels to Morioh to find his grandfather's illegitimate son, Josuke Higashikata, who is technically Jotaro's uncle despite Jotaro being older than him, as well as investigate the crimes of a Stand user. His Stand is Star Platinum, which compensates for its short range with incredible strength, speed, and precision, as well as the ability Star Platinum: The World, which lets Jotaro temporarily stop the flow of time.
• Joseph Joestar is Josuke's father and Jotaro's grandfather. His Stand is Hermit Purple, which manifests in the form of multipurpose thorny purple vines that allow him to divine information through electrical equipment or be utilized as ropes. Now in his late 70's, Joseph is incredibly feeble and senile.
• Rohan Kishibe is a famous manga artist who recently moved to Morioh. His Stand, Heaven's Door, allows him to temporarily turn a person into a book, with all of their memories written down akin to a novel. Rohan can read the memories, learn their weaknesses and secrets, as well as write down commands that they must follow. The power typically activates when the target sees Rohan's drawn artwork, but can also activate if Rohan draws something in the air with his finger. Rohan also stars in his own spin-off one-shot series by Araki called Thus Spoke Kishibe Rohan.
• Keicho Nijimura is Okuyasu's elder brother who caused the outbreak of Stand users in Morioh to create one whose Stand can end the suffering of their father after he was mutated by Dio Brando into a monstrous being with rapid regeneration. Keicho was later killed by Akira Otoishi when saving his brother from an attack by the guitarist's stand. Keicho's Stand, Bad Company, is an army of toy soldiers.
• Anjuro Katagiri, also known as "Angelo", is a depraved serial killer with an IQ of 160. Originally on death row for various acts of murder and sexual assault, including staging a post-mortem ransom for a young boy, Angelo is made a Stand User by Keicho and uses his water-based Stand Aqua Necklace to escape captivity and resume his killing spree in Morioh before ultimately confronting Josuke, murdering the youth's grandfather before being fused by Crazy Diamond's powers into a stone that becomes Morioh's tourist attraction Angelo Rock.
• Yukako Yamagishi is a high school student who develops an obsessive crush on Koichi. She kidnaps him and tries to form him into a "better man" by taking drastic measures to improve his grades. Koichi defends himself with the help of Echoes ACT2 and Yukako instead decides to admire Koichi from afar. However she soon sinks into depression and learns of a beauty salon named Cinderella from Joseph Joestar, which she uses to help rekindle her relationship with Koichi. Afterwards, she and Koichi become a couple. Her Stand is Love Deluxe, which is bound to her hair, allowing her to grow her hair to long lengths and freely manipulate it.
• Aya Tsuji is the owner of the Cinderella Salon, a beauty clinic in Morioh. She changes people's appearance and fate using her stand, Cinderella. She is killed by Yoshikage Kira after being forced to use her Stand to change his face so he can avoid capture.
• Akira Otoishi is an aspiring rock star guitarist. His Stand is Red Hot Chili Pepper, which draws its powers from electricity and can travel through various electrical outlets. He acquired his Stand after being shot with the Arrow by Keicho Nijimura.
• Yoshikage Kira is a hand-obsessed, mild-mannered serial killer who has been murdering women for more than 15 years. His Stand, Killer Queen, has the ability to create a bomb out of whatever it touches—including living people—allowing him to eliminate any evidence of his crimes. Kira has access to three bombs—the standard "Primary Bomb", a mobile heat-seeking "Secondary Bomb" known as Sheer Heart Attack, and a time-looping "Tertiary Bomb" known as Bites the Dust.
• Yoshihiro Kira is the ghost of Kira's father whose Stand, Atom Heart Father, allows him to remain among the living to protect Kira from within a photograph. Having acquired a Bow and Arrow from Enya prior to moving to Morioh, Yoshihiro uses the arrow to create Stand users in an attempt to keep Josuke's group away from Kira.
• Mikitaka Hazekura is a strange individual who claims that he is an alien. He befriends Josuke and Okuyasu, and occasionally helps them out. Mikitaka uses the ability Earth Wind and Fire, allowing him to shapeshift into inanimate objects. It is ambiguous whether or not Mikitaka is actually an alien, or a normal human – additionally, it is unclear whether or not Earth Wind and Fire is a Stand or a similar ability.
• Yuya Fungami is a member of a motorcycle gang that used the stand Highway Star to absorb the life source of others to recover from his injuries in the hospital, however he redeemed himself for his actions and agreed to help Josuke track down Koichi with his keen sense of smell, even going so far as to personally confront Terunosuke Miyamoto to save them both. Yuya's Stand has a range of 60km per hour and in addition to sucking the opponent's life force, it can divide itself and launch a barrage of punches.
• Tama is a British Shorthair that was struck by the arrow, then wandered into the Kawajiri household, and was accidentally killed by a broken glass bottle during Shinobu's attempt to chase him out. After his death, he was reborn as a hybrid of cat and plant due to the awakening of his stand, Stray Cat, that, along with reviving Tama, has the ability to create bubbles of air to shoot at enemies, which Yoshikage Kira exploits later on to create bubble bombs.
• Reimi Sugimoto is Yoshikage Kira's first victim. She was killed 15 years before the happenings of the manga, and waited as a ghost for someone whom she could warn about her killer.
• Kosaku Kawajiri is an average salaryman working as an employee at S-Corp. He is Shinobu Kawajiri's husband, and the father of Hayato Kawajiri. He, according to his wife, is extremely boring, and is shown to be very irresponsible with money, as he is in debt to his landlord on a house he cannot afford, bought an expensive car, and still has to pay for Hayato's college tuition. He is killed by Yoshikage Kira at the Cinderella Salon, who then proceeded to steal his identity, and integrate himself into his family.
• Shinobu Kawajiri is the wife of Kosaku Kawajiri, and Hayato's mother. After Yoshikage Kira killed Kosaku and stole his identity, Yoshikage Kira began treating Shinobu better than Kosaku did originally, renewing Shinobu's love for her husband, who, unbeknownst to her, and for a time, Hayato, was not in fact her husband.
• Hayato Kawajiri is a shy and intelligent schoolboy who realized his father Kosaku Kawajiri was murdered by Kira when the killer assumed his identity. Though Kira decided to use the boy as a means to kill Josuke's group, Hayato ended up being the killer's downfall. Hayato does not have a Stand of his own, but he winds up being the host of Killer Queen: Bites the Dust, resulting in anyone who tries to interrogate Hayato about Kira's current whereabouts spontaneously exploding, followed by time rewinding an hour.
• Tonio Trussardi is a talented Italian chief who runs a restaurant called "Trattoria Trussardi". He first encounters Josuke and Okuyasu when they are paying a visit to the grave of Keicho. His Stand is called Pearl Jam, which allows to cure, heal and strengthen a person, though it destroys whatever organ its healing first, giving off a gruesome impression. This Stand is different from the other Stands as it is born from Tonio's zeal to perfect his culinary arts rather than by an Arrow, hence he uses it mostly for his cooking methods.
• Tomoko Higashikata is the mother of Josuke Higashikata and the mistress of Joseph Joestar. A hot-tempered and fiercely protective woman, she is first shown violently confronting a man for catcalling her. Her enduring love for Joseph is revealed in a moment of mistaken identity, where she emotionally embraces Jotaro, believing him to be Joseph, before realizing her error.
