Crazy diamonds demonic heartbreak manga online

JoJo's Bizarre Adventure: Crazy Diamond's Demonic Heartbreak (ジョジョの奇妙な冒険 クレイジー・ダイヤモンドの悪霊的失恋 JoJo no Kimyō na Bōken: Kureijī Daiyamondo no Akuryō-teki Shitsuren) is a Spin-Off of JoJo's Bizarre Adventure, based on the parts Stardust Crusaders and Diamond is Unbreakable, and is considered of dubious canonicity. Its first chapter was announced to be included in the January 2022 issue of Ultra Jump, and was released on December 18, 2021.

Along with the one-shot Fujiko's Bizarre Worldly Wisdom -Whitesnake's Miscalculation-, which released on the same date, this series is notable for being one of the very first JoJo manga spinoffs to not be illustrated by Hirohiko Araki — it was written by Kohei Kadono (also known for writing the Golden Wind spinoff light novel, Purple Haze Feedback), and illustrated by Tasuku Karasuma, author of No Guns Life.

The story is set in Cairo, March 1999 — 10 years after the death of DIO, but before the start of Diamond is Unbreakable. It opens with Hol Horse, who was asked by an old woman to find a missing parrot who belonged to her son, who also trained the falcon Pet Shop before DIO killed him and confiscated the bird. Hol Horse agrees to help her find the parrot, but not before visiting his fellow comrades, all former servants of DIO, to discuss the impact DIO had left on them. Hol Horse and Boingo eventually find a lead to the far away town of Morioh, in Japan, where the former would cross paths with none other than Josuke Higashikata.

Crazy Diamond's Demonic Heartbreak provides examples of the following tropes:

  • Adaptation Expansion: The series explores the aftermath of the events of Stardust Crusaders extensively, along with introducing backgrounds for a few Diamond is Unbreakable characters:
    • Hol Horse, Mariah, and other surviving members of DIO's henchmen have moved on and gone on their separate ways, although they were still stricken with guilt and trauma due to DIO's manipulations on them. Mariah and Kenny G. end up settling down together, with the Oingo Boingo brothers occasionally visiting their hideout. Kenny refuses to meet Hol Horse face-to-face for unknown reasons.
    • Noriaki Kakyoin's death in Egypt became a news sensation, with numerous news outlets and magazines speculating about his demise. The manga also introduces Kakyoin's cousin, Ryoko Kakyoin.
    • In Diamond is Unbreakable, Ryohei Higashikata (Josuke's grandfather) was never promoted despite his hard work as a police officer. Here, a police officer openly speculates that this was due to having an illegitimate grandson.
    • Hol Horse and Boingo bore witness to Kakyoin's final Emerald Splash while trying to flee on the streets of Cairo, meaning they were there during the final battle with DIO.
    • Boingo doesn't consider Thoth to actually be a Stand. He suspects Thoth to be a tome from the actual Egyptian god it's named after, and that it's such a Clingy MacGuffin because he's supposed to guard it. It's also implied in a brief flashback that Oingo and Boingo's father was an abusive alcoholic.
  • All Part of the Show: After using Crazy Diamond to knock out a few mind-controlled girls and free them from Petsounds' Stand, Josuke proclaims that it was the conclusion of a street performance by Hol Horse, which calms down both the girls and the confused civilians.
  • Alliterative Name: Hol Horse. This spin-off also introduces Koji Kiyohara and Kazuki Karaiya.
  • Ambiguous Gender: It's unclear whether Karaiya is male or female, as their face, figure, and given name of Kazuki are all androgynous.
  • An Arm and a Leg: When trying to shoot Petsounds down, Hol Horse shears one of his wings off. It would be understandable to assume that the fall would kill Petsounds, but he returns at the end of Chapter 8 to help Karaiya silence Kiyohara.
  • Art Shift: The art style briefly changes to that of the "Oingo Boingo Brothers Adventure" book when Boingo and Hol Horse see where they need to go.
  • Bad People Abuse Animals: Ryohei reveals at the start of Chapter 8 that Kiyohara kept a collection of videos featuring him shooting animals to death. The subway crisis was him "graduating".
  • Bait-and-Switch: After Hol Horse points out that Josuke has a "fancy haircut", Josuke asks, "What the hell was that?!", and seemingly goes in for the strike on Hol Horse. In reality, he ends up punching the person in the car, because he nearly ran over Hol Horse.
  • Berserk Button: In a reverse of Josuke's usual reaction to people mocking his hairdo, the boy gets a smack across the face for mocking Ryoko's, who like him styled it based on someone she admires (in her case, Kakyoin).
  • Big Bad: The police officer Kazuki Karaiya is revealed to be the main villain and The Man Behind the Man of this story, right after Kiyohara has been arrested. We soon learn that his grandfather, seemingly inspired by Kars, has turned Karaiya the way he is now and Karaiya is trying to be at the apex of the world for both of them.
  • Brainwashed and Crazy:
    • Invoked by Petsounds' Stand. It attacks people from afar by stuffing their bodies with punch cards, which then control them against their will. The victims are fully aware of what's happening, but they are powerless to stop themselves. The victims can also recall and hear memories of DIO and his voice, for some reason.
    • We also get to see DIO implanting a flesh bud into Kakyoin's brain, which had an immediate effect on him. In previous media, the scenes of implanted flesh buds have been off-screen.
  • Call-Back: Many, to Stardust Crusaders:
    • Hol Horse now wears three wristwatches on his left arm, as a reminder of the time he failed to assassinate Jotaro and was shot by his own bullets, because his watch was a few seconds too fast.
    • When Hol Horse arrived at Morioh, he sees a man driven mad by what sounds like DIO's voice, driving his car onto the sidewalk and running over pedestrians — just like what DIO ordered Wilson Phillips to do. A flashback to the time Hol Horse tried and failed to kill DIO is also seen during this scene.
    • Mariah makes an ugly face when angry with Hol Horse like she did during her fight with Joseph and Avdol.
    • In Chapter 3, Petsounds' Stand replays Hol Horse's memory of DIO chiding him for failing to kill the Joestars back in Egypt, and controls him to shoot Inspector Hiraoka on the back of his head just like how he tried to assassinate DIO years ago. Fortunately, Hol Horse is able to escape without any blood on his hands when he sees a gleam from a green traffic light, reminding him of Kakyoin's final Emerald Splash and breaking Petsounds' control by giving him a different memory to focus on.
  • Chekhov's Gunman: Karaiya appears at the beginning of Chapter 3 and gets his name dropped during his brief appearance. He is revealed to be the main villain all along at the end of Chapter 8.
  • Close-Range Combatant: Boingo pieces together that Petsounds' Stand ability is more effective when he's closer to his victims, as when he and Josuke are affected by Petsounds' Stand when the parrot is extremely close to them, the memory they experience of Egypt is completely lifelike due to the feel and scent, and when DIO in the memory orders Pet Shop to use Horus on his original owner, the icicle has an actual effect on Josuke, who's unable to hit the icicle back due to Crazy Diamond phasing through it.
  • Connected All Along: Morioh turns out to have been Kakyoin's hometown.
  • Dirty Cop: Karaiya is revealed to be this in Chapter 8, allowing criminals like Kiyohara to roam the streets so long as they're "useful".
  • Disproportionate Retribution: Hol Horse and Mariah are discussing their past under DIO and how his immense charisma let him manipulate them. Hol Horse says that, "The people who fall for a conman's tricks may be fools, but at the end of the day, they're victims all the same." The insinuation that she's a fool causes Mariah to explode with rage, using her Stand to turn Hol Horse magnetic and nearly killing him. Subverted when it turns out Mariah was just messing with Hol Horse, as revenge for him having taken advantage of Boingo in the past.
  • Exploding Closet: Justified; Hol Horse accidentally shoots open a closet full of swords, which start chasing him thanks to the magnetism induced on him by Mariah's Stand.
  • Extreme Doormat: Petsounds itself has no ambitions on its own and only acts when it is commanded to do so. For ten years, it didn't use its powers and therefore didn't make any chaos. However, once Petsounds got stolen, it serves its new tamer without question.
  • First-Name Basis: Due to being relatives, Ryoko naturally refers to her cousin Kakyoin by his given name Noriaki.
  • Flechette Storm: Mariah's Bastet makes Hol Horse magnetic, which causes darts and swords to fly at him.
  • Gambit Roulette: It's revealed in Chapter 8 that DIO was specifically targeting Kakyoin as his tool to take out Jotaro, being the most recent member of the Joestar Bloodline, and that he was hoping for Ryoko to get lost while the Kakyoin family was on vacation in Egypt so that he could corner her while Kakyoin is looking for her, which ultimately does end up happening, giving DIO the perfect opportunity to launch a flesh bud directly in Kakyoin's forehead whilst he's defending Ryoko.
  • Good Thing You Can Heal: A lot of the injuries and damage are reverted back to their previous state thanks to Josuke's Crazy Diamond, thus avoiding and casualties within the civilian population.
  • Grave-Marking Scene: Halfway through the first chapter, Noriaki Kakyoin's cousin, Ryoko, is seen tending to his grave in Morioh.
  • Heel–Face Turn: Multiple villains from Stardust Crusaders, including Mariah, Kenny G., and Boingo, regret working for DIO and now want to live normal lives.
  • Heroic Willpower: Hol Horse demonstrates a surprising amount of this over the story (given his long-standing reputation as an avaricious coward), which lets him survive Petsounds' attempts to control him. First, he avoids having to shoot Inspector Hiraoka by focusing on a different memory (in particular, a reflected green traffic light, reminding him of Kakyoin's final Emerald Splash against DIO), and escapes the helicopter gunship illusion by rationalizing to himself that the fear he's feeling is nothing compared to his failed attempt to kill DIO.
  • It's All My Fault: Ryoko is revealed to blame herself for her cousin Noriaki Kakyoin falling under DIO's control. When they were in Egypt before the events of Stardust Crusaders, Ryoko got lost in Cairo and Kakyoin went to look for her. This left them alone with DIO that night, and Kakyoin's effort to protect his cousin led him to be infected by one of DIO's flesh buds. Ryoko believes that if she hadn't gotten lost that night, then her cousin would still be alive.
  • Kansas City Shuffle: After having to face a multitude of Morioh citizens under the influence of Petsounds' Stand, Hol Horse and Josuke make it for the subway station, thinking its spacing would be too cramped for Petsounds to sneakily fly through. As it turns out, though, this is the exact situation Petsounds wanted the two to be in, and uses his Stand to force everybody in the station to reenact the events of a military helicopter shooting in Egypt.
  • The Man Behind the Man: Karaiya is revealed to have been controlling Kiyohara the whole time and he is the one who got his hands on Petsounds.
  • Mind Rape: It's retroactively shown that most of DIO's minions that weren't given flesh buds or weren't already evil were subjected to emotional manipulation and gaslighting that ultimately made them unwittingly pledge loyalty to DIO. Hol Horse and Mariah are shown to still be suffering the effects of it even 10 years following DIO's death.
  • Ms. Fanservice: As in Stardust Crusaders, Mariah wears a revealing outfit. Multiple panels focus on her body.
  • Mythology Gag:
    • The narration in the first chapter mentions pursuing a calamity, referencing the Wonder of U storyline in JoJolion.
    • The missing parrot, named Petsounds, which was previously owned by Pet Shop's previous owner, is likely a reference to the parrot seen with DIO early in the Stardust Crusaders manga, which never showed up again and was fully replaced with Pet Shop in the anime.
    • Additionally, if anyone is controlled by Petsounds' Stand, their eyes will turn blank and gain a circular dimpled texture, similar to the eyes of the Stand Moody Blues from Golden Wind. Much like Moody Blues, Petsounds's Stand's ability involves replaying past events.
    • At the end of Chapter 5, when Ryoko consults Thoth, it tells her not to confront Hol Horse about DIO directly and that, "the detour will get you there the quickest," a reference to Gyro's fifth and final lesson, "The shortest route was the detour."
  • Older than They Look: Boingo looks almost no different from how he looked 10 years ago, still being short and wearing similar clothes. The only physical indication that he's aged is the tiny stubble under his chin.
  • Original Generation: While this spin-off has characters from multiple parts (mostly Part 3 and Part 4), it also introduces a few new characters: Ryoko Kakyoin, Petsounds, Kazuki Karaiya and his grandfather, and Koji Kiyohara.
  • The Paranoiac: Because he suffered a humiliating defeat due to an incorrectly-adjusted wristwatch during Stardust Crusaders, Hol Horse now wears three watches to keep track of time, fussing about it to himself when one of them is out of sync.
  • Posthumous Character: The two most prominent ones are DIO and Kakyoin, who both affect the current set of characters heavily. The memories of DIO still haunt his former minions, while Ryoko is desperately driven to find the truth behind Kakyoin's death. The original tamer of Petsounds and Pet Shop has also been killed by DIO in the past, which is why the remaining bird, Petsounds, is so important to his mother.
  • Punch-Clock Villain: Petsounds hasn't used its abilities for 10 years, but it is doing anything its current tamer is commanding it to do, regardless if its action are evil or not.
  • Saved by Canon: When it comes to human casualties, pretty much everyone other than the bad guys are safe, not only because of Crazy Diamond's healing powers, but also because Josuke hasn't discovered yet that bringing people back from the dead is impossible. Which means any attempt of him healing people is guaranteed to be successful.
  • School Uniforms are the New Black: The spin-off takes place in March, which is during the break between the third trimester and first trimester. Despite this, Ryoko and Josuke are wearing their school uniforms despite the fact that a) Ryoko has already graduated from high school, and b) Josuke has not officially entered his new high school yet. Ryoko is still wearing her uniform because she's clinging to the past, while Josuke is wearing his uniform because he's looking forward to for the next part of his life.
  • Senpai/Kōhai: Despite not even attending the same school, Josuke refers to Ryoko as "Senpai" because of her seniority.
  • Shell-Shocked Veteran: It's shown that even 10 years later, Hol Horse and Mariah still feel the mental scars of their time as DIO's servants. Mariah regularly has dreams about DIO where she grovels and apologizes to him, while Hol Horse has a Freak Out when he thinks he heard DIO's voice. Boingo's no picnic, either—Thoth shows that he still has massive insecurities about being under DIO's control, and one page says being apart from the book is a step closer to being free from DIO's influence.
  • Shoot Out the Lock: Done accidentally by Hol Horse — he attempts to shoot away the darts flying at him, but he didn't see where he was shooting and the bullets end up breaking the lock to a closet full of swords, which then start to fly at him as well.
  • Shoot the Dog: Despite promising the tamer's mother that he would bring Petsounds back to her alive, Hol Horse knows that the parrot will continue to cause casualties with its Stand. He chooses to shoot down Petsounds to prevent further catastrophe. Although we later see that Petsounds is still alive.
  • Shout-Out:
    • Hol Horse references the Japanese drama series Oshin.
    • Ryoko asks Josuke if his hair is inspired by a replicant from Blade Runner.
    • The parrot Petsounds is named after The Beach Boys album Pet Sounds.
  • Time Master: Averted. Not literally, but metaphorically. While Karaiya can't manipulate time itself, he does get his hands on Petsounds and later Thoth, which have "the power of the past and the future", respectively. Petsounds' Stand has the ability to make people reenact and experience past events, even if it's not their own past. Thoth is a manga/comic that can predict the near future.
  • Ugly Guy, Hot Wife: Mariah, a woman very easy on the eyes with pronounced legs, ended up getting together with Kenny G., who is a short, imp-like man.
  • Villainous Lineage: In Chapter 9, Karaiya is revealed to be taking after his grandfather in terms of being evil. His grandfather was a vampire, and revered Kars as a god, seeing his transformation into the Ultimate Life Form firsthand in Switzerland back when he was a human soldier in World War II.
  • Vomit Indiscretion Shot: After Josuke heals the possessed man who swerved his car at him and Hol Horse, the man suddenly vomits out what appears to be a deck of punch cards, which vaporizes almost immediately. This would later happen to other characters affected by Petsounds' Stand.
  • Walking Spoiler: Kazuki Karaiya. Anything from his second appearance in the story and beyond is classified as a spoiler, due The Reveal of him being the Big Bad. The only thing about him that doesn't count as a spoiler is his first appearance.
