Diamond Is Unbreakable - Characters

Characters

Josuke Higashikata (東方 仗助, Higashikata Jōsuke?)

The protagonist of this story arc. A freshman in the town of Moriō, Josuke is the illegitimate son of Joseph Joestar. His Stand is Crazy Diamond (クレイジー・ダイヤモンド, Kureijī Daiyamondo?), named after "Shine On You Crazy Diamond", which has the ability to restore objects to their original form; including others people's injuries.

Jotaro Kujo (空条 承太郎, Kujō Jōtaro?)

Protagonist of the previous arc, Part 3 Stardust Crusaders, and half-nephew to Josuke. He goes to Moriō to find Josuke, Joseph Joestar's son, as well as investigate a Stand user.

Koichi Hirose (広瀬 康一, Hirose Kōichi?)

A classmate of Josuke's who meets him when Jotaro is searching for Josuke, resulting in the two becoming quick friends. Koichi is a young freshman in high school, and despite his age, he is very short. Throughout the series, he forms a student-teacher relationship with Jotaro. His Stand is Echoes (エコーズ, Ekōzu?), named after "Echoes", which has three distinct forms, or Acts (Koichi can only call upon one at any given time). Echoes Acts 1 and 2 can replicate sound effects and attach them to anything, which result in that happening to the object (i.e. attaching the word "whoosh" causes a gust of wind to blow by) Echoes Act 3 loses the former abilities and gains the ability "Freeze" which causes a target to become very heavy, it can also communicate with Koichi.

Okuyasu Nijimura (虹村 億泰, Nijimura Okuyasu?)

One of the two Nijimura brothers who were responsible for creating the majority of Stand users in Moriō via the Bow and Arrow. Okuyasu is overly dependent on his elder brother Keicho to make hard decisions. After his brother died, he sought revenge against the user of Red Hot Chili Pepper, Akira Otoishi, and becomes friends with Josuke and Koichi. Okuyasu's father is a bizarre creature, mutated by Dio Brando's spores when Okuyasu was only seven. At first, Okuyasu and Keicho plotted to kill their father to relieve him of his suffering, creating Stand users via the Bow and Arrow for this very purpose. Okuyasu rather dislikes Rohan because of what Rohan tried to do to him when they first met. His Stand is The Hand (ザ・ハンド, Za Hando?), possibly a reference to The Band, who's right hand is used to temporarily erase the space where the it moves, teleporting the objects closer to Okuyasu. While this ability is quite useful, he is rather unintelligent rarely using it to its potential.

Rohan Kishibe (岸辺 露伴, Kishibe Rohan?)

A famous manga artist who recently moved to Moriō. His Stand Heaven's Door (ヘブンズ・ドアー（天国への扉）, Hebunzu Doā?), named after "Knockin' on Heaven's Door", allows him to read the memories of its target as well as write down commands that they must follow, most commonly "Can not attack Rohan Kishibe." A restriction on his power is that the target must see his artwork, but this can be supplemented by drawing an "image" in the air with his finger. He eventually befriends Koichi, and subsequently helps Josuke's group learn Yoshikage Kira's new identity.

Rohan also stars in several spin-off one-shots by Araki; Thus Spoke Rohan Kishibe ~Episode 16... Confessional~ (1997), Thus Spoke Rohan Kishibe -Mutukabezaka- (2007), Rohan au Louvre (2010), Rohan Kishibe Goes to Gucci (2012) and Thus Spoke Rohan Kishibe ~Episode 5 Millionaire Village~ (2012).

Yukako Yamagishi (山岸 由花子, Yamagishi Yukako?)

She is a classmate of Josuke's and Koichi's, who has an obsessive crush on Koichi. Her obsession leads to her trying to force him into loving her, effectively resulting in a battle between the two. 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. Her Stand Love Deluxe (ラブ・デラックス, Rabu Derakkusu?), named after Love Deluxe, is bound to her hair and can lengthen to any distance.

Araki drew the cover for the 2009 single "Breeeeze Girl" by the rock band Base Ball Bear, it features Yukako in a panel from the manga.

Joseph Joestar (ジョセフ・ジョースター, Josefu Jōsutā?)

Protagonist of Part 2 Battle Tendency, Josuke's estranged father and Jotaro's grandfather. He comes to Moriō to meet Josuke and help the others with the Bow and Arrow situation, but only assists in minor side-stories. He later adopts Shizuka, an abandoned infant and Stand user who he encounters in one of these.

Tomoko Higashikata (東方 朋子, Higashikata Tomoko?)

Josuke's mother, who is single and somewhat strict. She does not like to be hit on by other men because she is still madly in love with Joseph Joestar.

Reimi Sugimoto (杉本 鈴美, Sugimoto Reimi?) and Arnold (アーノルド, Ānorudo?)

Yoshikage Kira's first victim and her dog. She was killed 15 years before the happenings of the manga and waited as a ghost for someone she could tell the story to and inform them of the serial killer. At the end of the arc, she informs Yoshikage Kira of how he died, and because of his death is finally able to rest peacefully. Reimi is named after See Emily Play (with Reimi serving as an anagram for Emiri, the Japanese pronunciation of "Emily"). Arnold is named after Arnold Layne.

Shigekiyo Yangu (矢安宮重清, Yangū Shigekiyo?)

Nicknamed "Shigechi" (重ちー, Shigechī?), Shigekiyo is an outcast who feels welcome once he becomes acquainted with Josuke and Okuyasu. His stand is Harvest (ハーヴェスト（収穫）, Hāvesuto?), named after Harvest, which is divided into multiple small individuals and used by him to collect stray objects. This ability is the catalyst of his friendship with Josuke and Okuyasu after they use it to earn large amounts of money, not after getting into battle though due to Shigechi's own greed. Due to a mix-up, he ends up discovering Yoshikage Kira's hand from one of his victims and is killed by him for it, resulting in Josuke's group's resolve to find Kira.

Tamami Kobayashi (小林 玉美, Kobayashi Tamami?)

A minor character. He is first introduced as a villain, attacking Koichi Hirose and his family, but after being defeated becomes a friend of the group, even calling Koichi "Boss Koichi". His Stand is The Lock (ザ・ロック（錠前）, Za Rokku?), which forms a lock on the victim's heart that continues to grow as he makes them feel more and more guilty.

Toshikazu Hazamada (間田 敏和, Hazamada Toshikazu?)

He is a classmate of Josuke's and a Stand user, who originally appeared as a villain after being tracked down by Josuke. His Stand Surface (サーフィス（うわっ面）, Sāfisu?), possibly named after Surface, is a mannequin that copies his target exactly, including appearance and voice, and forces the person to mimic its own movements. However after being defeated he becomes somewhat of friends with the group.

Mikitaka Hazekura (支倉 未起隆, Hazekura Mikitaka?)

A teenager who was shot by the Arrow by Yoshikage Kira's father, however it does not properly pierce him, and is found by Josuke and Okuyasu when they happened to be passing by. He claims to be an alien and gives his full name as Nu Mikitakazo Nshi (ヌ・ミキタカゾ・ンシ?), supposedly his alien name, but they just ignore it until later interactions cause them to believe otherwise. He has the strange ability Earth, Wind & Fire (アース・ウインド・アンド・ファイヤー, Āsu Uindo Ando Faiyā?), named after Earth, Wind & Fire, 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.

Yuuya Fungami (噴上 裕也, Fungami Yūya?)

A vain and spoiled teenager who gained his Stand while shot by the Arrow when driving his motorcycle. As such he is hospitalized with multiple lesions and fractures and attempts to use his Stand to siphon away the energies of random people to heal himself. Discovered by Josuke, he was healed by Crazy Diamond, then injured again in retaliation for his actions. He's later healed again and aids in the battle against Terunosuke Miyamoto. His Stand Highway Star (ハイウェイ・スター, Haiwei Sutā?), named after "Highway Star", allows him to gain the energy of his victims and grants him a supernatural sense of smell and perception, allowing him to track people from afar. Highway Star also has a limitless range and a speed of 60 mph.

Aya Tsuji (辻 彩, Tsuji Aya?)

A young woman who fancies herself to be a real-life Fairy Godmother. As such she owns the Cinderella Beauty Salon in Moriō and uses her stand also called Cinderella (シンデレラ, Shinderera?), named after Cinderella or the band of the same name, to give young women complete makeovers. With it she can alter the features of anyone subjected to her power, modifying their "destiny", such as granting a girl the ability to find a date or her true love. However, the changes are temporary, unless her customers apply a special lipstick every 30 minutes. Failing to do so causes the altered body feature to wither away, disfiguring them. She uses her powers to make Yukako and Koichi closer, then she's forced to disguise Yoshikage Kira, before being killed by his Killer Queen.

Shizuka Joestar (静・ジョースター, Shizuka Jōsutā?)

An abandoned infant on the streets of Moriō, who is eventually found by Josuke and Joseph and later adopted by Joseph into the Joestar family. She is rarely seen in the series, and whenever she does make an appearance, she is usually in the care of Joseph. However, she did play a part in Rohan's confrontation with Ken Oyanagi, as Rohan used her Stand powers to help him. At the end of the arc, it is said that Suzi Q - Joseph's wife and Jotaro's grandmother - discovers Joseph has brought home a child and mistook her to be another one of her husband's illegitimate children. Her Stand is Achtung Baby (アクトン・ベイビー, Akuton Beibī?), named after Achtung Baby, which has the ability to make her body transparent, as well as anything else surrounding her within a one meter radius.

Hayato Kawajiri (川尻 早人, Kawajiri Hayato?)

Son of Kosaku Kawajiri, the man who's identity Yoshikage Kira stole, he's a shy, secretive intelligent schoolboy. He notices his father's recent odd behavior and uses a camera to spy on him. Eventually Kira admits who he is to him and seemingly kills him, however he soon reappears and is used by Kira to kill Josuke and company. Kira used his new Bite the Dust technique on him, successfully killing them and starting a time-loop. However, Hayato outsmarts Kira forcing him to end the technique, starting the final battle which Hayato assists in.

Tonio Trussardi (トニオ・トラサルディー, Tonio Turasarudī?)

A chef who runs an Italian Restaurant in Moriō, which is actually his own house. Unlike most other Stand users that Josuke meets, Tonio's was not awakened by an Arrow but by his zeal to perfect his culinary arts and does not mean any harm to them, originally. 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?), named after the band of the same name, heals people by intrinsically telling Tonio what their injuries are and he prepares a dish for them that they will undoubtedly find delicious.

Anjuro Katagiri (片桐 安十郎, Katagiri Anjūrō?)

Despite having an IQ of 160, Anjuro Katagiri (Angelo (アンジェロ, Anjero?) to the newspapers) chose to embark on a life as a depraved career criminal. He was caught after attempting to ransom a kidnapped heir, and sentenced to death for slaughtering him (long before he tried to collect the ransom). However, while awaiting execution he was visited by Keicho Nijimura, who had been guided to him by the Arrow. After being pierced by the Arrow, resulting in the awakening of his Stand Aqua Necklace (アクア・ネックレス（水の首かざり）, Akua Nekkuresu?), Angelo somehow escaped prison and returned to his old hunting grounds of Moriō, where he would ultimately confront Josuke. He acted as a milkman to Josuke's mother, hiding his Stand underneath one of the bottles and waited until he was carried inside. When Josuke returns home, she inadvertently drinks Aqua Necklace. Josuke saves her by punching her stomach with Crazy Diamond and trapped it within a spare whiskey bottle. While he was asking directions on the phone with Jotaro, Angelo escapes and kills Josuke's grandfather. He later lead Jotaro and Josuke into a fight, but was defeated. Josuke, declaring that he doesn't want to be like Angelo, spared his life. However, he pummeled the criminal into a wall, fused both entities together and made him the newest tourist attraction of the town: "The Living Monument". Antonio stayed alive and is imprisoned there for the rest of the manga. His Stand Aqua Necklace can possess anything liquid, even if the liquid becomes a mist.

Keicho Nijimura (虹村 形兆, Nijimura Keichō?)

Okuyasu's elder brother. As his father was mutated by Dio Brando into a monstrous, addled being, he uses the Bow and Arrow, creating several Stand users, hoping that one of them would be able to put his father out of his misery. He's killed by Red Hot Chili Pepper while saving his brother. His Stand Bad Company (バッド・カンパニー（極悪中隊）, Baddo Kanpanī?), named after Bad Company, is an entire army of toy soldiers.

Akira Otoishi (音石 明, Otoishi Akira?)

A young man that inspires to be a rock star guitarist, who was shot with the Arrow by Keicho. He kills Keicho and takes the Bow and Arrow using his Stand Red Hot Chilli Pepper (レッド・ホット・チリ・ペッパー, Reddo Hotto Chiri Peppā?), named after the Red Hot Chili Peppers, an electricity Stand that can travel through wires and other electrical systems as well as being controlled from a long distance. Josuke and his group then search to find Chilli Pepper's user, even calling Joseph Joestar to Japan to use his Stand which can locate anyone. However Akira learns of this and a battle in sues, with Akira on the winning side for most of the fight until Joseph's boat arrives and he leaves to board it and try to kill him. His attack is foiled through Okuyasu's luck and he is sentenced to three years in jail for the things he stole, namely other people's electricity.

Bug Eat (虫喰い, Mushikui?) and a brown rat (虫食いでない, Mushikuidenai?)

Two large field rats, one named Bug Eat the other not named, that were shot by the Arrow during the time it was in Akira Otoishi's possession. Together they killed the inhabitants of Moriō's farmlands. This drew the attention of the Speedwagon Foundation, which had Jotaro and Josuke go on a hunting mission to investigate. They both possess the Stand Ratt (ラット, Ratto?), named after Ratt, which takes the form of a small airship that transforms into a tank and shoots darts that melt the human skin. They both have unusual levels of intelligence, but are hunted down and later placed in the custody of the Speedwagon Foundation.

Ken Oyanagi (大柳 賢, Ōyanagi Ken?)

The first of the Stand users Yoshihiro Kira creates with the Bow and Arrow to protect his hiding son. Ken is a young boy who loves to play games, especially when it comes to deciding who has the right to what, therefore making it as some sort of gamble. After being shot by the Arrow and having his Stand awakened, Ken goes on to confront Rohan, continuously following him all over Moriō and getting into altercations with him. During the course of these events, Ken slowly gains control of Rohan's Stand as he uses his own Stand Boy II Man (ボーイ・II・マン, Bō Tsū Man?), named after Boyz II Men. It has the ability to partially take control of his opponent's Stand power by winning a game of Rock, Paper Scissors, with three consecutive wins needed to gain full control. However, Rohan manages to outsmart the boy and defeats him, gaining full control of his Stand, Heaven's Door, back.

Toyohiro Kanedaichi (鋼田一 豊大, Kanedaichi Toyohiro?)

Kanedaichi, an assumed name, is a Stand user that Josuke meets on the outskirts of town. His Stand Superfly (スーパーフライ, Sūpāfurai?), named after Curtis Mayfield's Super Fly, takes the form of a telephone tower and confines the user to an area around the tower. Should another person enter Superfly'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.

Masazo Kinoto (乙 雅三, Kinoto Masazō?)

Masazo is a insurance agent, who visits Rohan's house after it burned down. He was hit by the arrow beforehand, but does not seem to be an enemy because he shows no effort of killing Rohan. His Stand Cheap Trick (チープ・トリック, Chīpu Torikku?), named after Cheap Trick, does not want his user's back to be seen, causing Masazo to always walk up against walls and even slide on the floor on his back. 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.

Stray Cat (ストレイ・キャット, Sutorei Kyatto?)

Once a regular cat, he's mistakenly killed by Shinobu Kawajiri after being hit by the Arrow. As such instead of staying dead he fuses with his Stand power, becoming a bizarre mix of plant and animal with the power to shoot compressed air towards his enemy. Noticed by Yoshikage Kira, he's then used to supplement his powers and carried inside Killer Queen.

Terunosuke Miyamoto (宮本 輝之輔, Miyamoto Terunosuke?)

One of Yoshihiro Kira's followers, Terunosuke kidnaps Koichi's mother to trap both Josuke and Koichi in his Stand's powers to keep them from defeating Kira. His Stand Enigma (エニグマ, Eniguma?), named after Enigma, allows him to trap people in sheets of paper if they show their fear to him. Once they are trapped in the paper, so long as it is folded in half they will remain trapped.

Yoshikage Kira (吉良 吉影, Kira Yoshikage?)

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?), named after "Killer Queen", 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 in sues. He is killed when Jotaro knocks him into the path of a fire truck, and is later shown as a ghost, at the mercy of the ghosts of his "girlfriend" hands.

Killer Queen No. 1 turns anything it touches into a bomb, while No. 2 titled Sheer Heart Attack (シアーハートアタック, Shiā Hāto Atakku?), named after "Sheer Heart Attack", is a small indestructible fully automated tank-treaded bomb that attacks the object with the highest temperature in the area. He acquires No. 3 titled Bite the Dust (バイツァ・ダスト, Baitsa Dasuto?), taken from "Another One Bites the Dust", towards the end of the arc when he is accidentally stabbed with the Bow and Arrow. This ability plants miniaturized Killer Queen on a person and kills anyone that tries to learn info about Kira from them, as well as protects that person. When they learn Kira's identity Killer Queen enters their field of vision, then enters their eye and explodes. The period of time in which the victim learns his identity and the bomb explodes is repeated in-loop until Kira learns who the bomb killed. 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, which was published in the magazine Allman in 1999 and follows him as a ghost after his death.

Yoshihiro Kira (吉良 吉廣, Kira Yoshihiro?)

Yoshihiro Kira is Yoshikage Kira's father who died sometime before Diamond Is Not Crash. His death activates his Stand Atom Heart Father (アトム・ハート・ファーザー, Atomu Hāto Fāzā?), named after the Pink Floyd album Atom Heart Mother, which enables him to be bound to photographs and manipulate anything within the photograph, including people.
