After Jonathan's death, his son, George Joestar II travels with Erina to the Canary Islands in Spain on the island of La Palma. There, he pledges his love to Lisa Lisa and eventually grows up to become a World War I Air Pilot.
In another story, kid detective Joji Joestar sets out on a bizarre quest to fix the space-time continuum after it's ruptured from Made in Heaven reseting the world 36 times.
- The information below derives from a Light Novel not written by Araki. As such, it may or may not be considered canon.)
The odd-numbered chapters of the story tells of how George, Lisa Lisa, and another girl grew up together, eventually leading to Jorge joining the Royal Air Force and marrying Elizabeth. Their wedding ends prematurely due to a zombie invasion, but after the universal reset, everything is brought back to normal.
The other chapters, however, are everything else. Set in the 20th century after Made In Heaven resets the world exactly thirty-six times, it focuses on kid detective Joji Joestar who, while investigating a recent incident, comes across and meets up with the original ("Universe-J") Giorno and Rohan. Giorno has survived due to his Stand Gold Experience Requiem nullifying the effects, Rohan survives by being too preoccupied with his manga to realize Made In Heaven was activated. They discover that the world has reset 36 times, resulting in various and random changes going through-out the individual parts of JoJo's Bizarre Adventure, but in each edition of the world in Battle Tendency, the plot remained consistent: specifically, 36 versions of Kars became the Ultimate Lifeform and now live on Mars and the Universe-J Kars has become a guardian of human life. There was also one rendition of Steel Ball Run, resulting in the creation of the Funny Valentines.
Detective Joji goes out to fix the universes with Universe-J Giorno and Rohan alongside an alternate universe Passione and one of the alternate universes of Part 4, in which the Nijimura brothers Okuyasu and Keicho (now known as Muryotaisu and Fukashigi respectively) have pipe-shaped hair styles and Koichi is of regular height (now known as Koji). Along the way, they eventually reach space, and call upon the thirty-six Kars for assistance. Universe-J Kars uses a chance encounter with Yoshikage Kira to obtain the use of Killer Queen by convincing it over to his side. Then, using Bites the Dust, Universe-J Kars not only completely resets the world, forcing it to become Universe-J again, but also obtains Made in Heaven Requiem in the process. It all ends with the Universe J-Kars's complete reset at the wedding of Jorge and Elizabeth.
All the Stands from the alternate universe the characters are currently in are named after movies, instead of music. However, King Crimson and Killer Queen remain the same namewise and there is a Dirty Deeds Done Dirt Cheap. There are also three new types of Stands that are not exactly "Stands":
- Wounds (ウゥンド Wundo) are created from repeated damage to the mind and body, are less controllable than Stands are, and tend to serve a purpose of stopping the user's source of pain.
- Bounds (バウンド Baundo) are forces taken directly from the environment that the user manipulates.
- And Beyonds (ビヨンド Biyondo) are, as their name implies, abilities that extend beyond time and space.
- Jorge Joestar (ジョージ・ジョースター Jōji Jōsutā): Otherwise known as George Joestar II. His story remains the same, although he grows up on the Spanish island of La Palma, and thus goes by the name "Jorge" instead of "George".
- Joji Joestar (城字・ジョースター Jōji Jōsutā): Joji is 15, a detective, and although of British descent he was adopted by a Japanese family and thus lives in Japan. He goes to Morioh to investigate a murder, only to be thrown into the plot. He has only ever appeared in the 35th and 36th universe resets, which is why he's relevant.
- Tsukumojuku Kato (加藤 九十九十九 Katō Tsukumojūku): Jorge's best friend, also 15. There is also another version of him who is 19 years old and is the one who gives Joji the tip about the murder.
- Kars: 36 in count, all ultimate beings. Universe-J Kars comes to assist Jorge at some point of the story and becomes a close ally in the form of a guardian figure. Noticeably, his eyes are blue, not red or gold, and it becomes a defining trait. He has seen the worth in humanity as well and because of this has turned over a new leaf. Jorge speaks to him humbly, calling him "Mr. Kars" or "Kars-senpai". He "remembers" Stands, and has the ability to steal another person's Stand if he chooses to. Most Stands that he steals will have "Ultimate" added to their name; Stands that fit this description include U-Boat Ultimate, Dune Ultimate, The World Ultimate, Whitesnake Ultimate, C-Moon Ultimate Requiem, Made in Heaven Ultimate Requiem, and Ultimate D4C.
- Giorno Giovanna: The original Giorno finds and meets the original Rohan and leads the attack to restore the worlds back to normal. There is also another Giorno, very likely the one for the alternate universe Passione that is met, that has been possessed by Diavolo.
- Rohan Kishibe: Universe-J Rohan, not much is known about his role. He's the one who called in about the murder in Morioh, which Kato reports about and is how Joji ends up there.
- Yoshikage Kira: Possibly Universe-J as well; this Kira seems to be the Dead Man's Questions Kira, but comes with Killer Queen post-Arrow. Nonchalant, but once again obsessed with hands. On the 36th iteration, Killer Queen is stolen by Kars.
- Lisa Lisa: Only for Jorge Joestar's universe, known as Elisabeth Straizo (エリザベス・ストレイツォ Erizabesu Sutoreitso) in JORGE JOESTAR.
- Straizo: Also only for Jorge Joestar's universe.
- Penelope de la Rosa (ペネロペ・デ・ラ・ロサ Penerope De Ra Rosa): Original character. She grew up with Jorge, she has both an unnamed "Wound" and a "Beyond" named Cube House (キューブハウス Kyūbu Hausu). The Wound hangs people within closed doors, Cube House functions similar to Burning Down the House but can escape time and space. She has nightmares about clowns regularly, which the Wound looks like.
- Jonathan Joestar: There are two versions of Jonathan Joestar in the story. The first is Jorge's father, the original Jonathan Joestar from Universe-J. He is brought back to life and obtains DIO's Stand The Passion (
情熱Za Passhon). The other is an ancestor of Joji Joestar going back six generations who died while stopping his adoptive brother Dio Brando from committing a train robbery.
- Erina Joestar: There are also two versions of Erina. The first is the original Erina from Universe-J, who cares for Lisa Lisa, Jorge, and Penelope, on La Palma. The other is again Joji's ancestor.
- Reimi Sugimoto: In JORGE JOESTAR, Reimi is alive. It is not known if she is the original Reimi from Universe-J or an alternate universe Reimi.
- Aya Tsuji: An alternate universe incarnation. Her Stand has the same abilities but is named Face/Off (フェイスオフ Feisu Ofu).
- Koji Hirose (広瀬 康司 Hirose Kōji): An alternate universe incarnation of Koichi Hirose. His Stand Blue Thunder (ブルーサンダー Burū Sandā) is a head propeller.
- Muryotaisu Nijimura (虹村 無量大数 Nijimura Muryōtaisū): An alternate universe incarnation of Okuyasu Nijimura. His Stand Grand Bleu (グランブルー Guran Burū) summons three somewhat disobediant dolphins named Jack, Enzo, and Joanna. They can swim at fast speeds.
- Fukashigi Nijimura (虹村 不可思議 Nijimura Fukashigi): An alternate universe incarnation of Keicho Nijimura. His Stand NYPD Blue (NYPDブルー Enu Wai Pī Dī Burū) takes the form of a reliable 30-year old cop from New York.
- Shigetaka Yangu (矢安宮 重孝 Yangū Shigetaka): Alternate universe Shigekiyo Yangu. His Stand Stray Dog (ストレイドッグ Sutorei Doggu) controls stray dogs.
- Bruno Bucciarati: Alternate universe. His Stand is now named Stepmom (
グッドナイト・ムーンGuddonaito Mūn, Goodnight Moon) and is a feminine Sticky Fingers that relies on needle and thread rather than zippers.
- Leone Abbacchio: Alternate universe. His Stand is Videodrome (ヴィデオドローム Videodorōmu), which can take memories in the form of video tapes, akin to Whitesnake, and use them to become similar to Moody Blues for up to 24 hours.
- Guido Mista: Alternate universe. His Stand The Iron Ladies (
アタック・ナンバーハーフAtakku Nanbā Hāfu, Attack Number Half) is the same as Sex Pistols, but is now instead made up of transsexual volleyball players, each with their own uniforms and commands.
- Narancia Ghirga: Alternative universe. His Stand U-Boat (Uボート Yū Bōto), is shaped like a submarine and can swim through bodies to cause internal damage with bullets and missiles.
- Dio Brando: Several, in fact:
- Phantom Blood Dio, who became the Ultimate Lifeform and then a monster. He can be considered the main villain. His Stand, "The Passion", allows him to predict his opponents' actions.
- Dio who replaces the Saint's Corpse, with his bones later resurrecting Jonathan.
- A fake Dio that appears in one iteration of Stardust Crusaders.
- Joji Joestar-universe Dio who went insane after seeing his step-brother Jonathan die in the train robbery.
- Enrico Pucci: Universe-J Pucci, who became an astronaut likely to hide from the heroes. His Stand is permanently Made In Heaven, but it is eventually stolen by Kars and transformed into Made In Heaven Requiem.
- Diavolo: There are just as many Diavolo's as there are Kars, but only the ones that completely disengaged from Doppio survived their arc. Only two or three are known: the Universe-J Diavolo (who is still in his cycle of multifarious deaths), a Diavolo whom split from Doppio to possess Giorno, and a Diavolo that the alternate universe Passione is pursuing. It's unknown if the latter two are one in the same, or if they are connected to the alternate Universe Giorno that also exists.
- Doppio: Specifically, the one from the Diavolo-possessing-Giorno timeline. He has an unnamed Stand that allows him to transform any object into a phone. Rohan attempts to use Heaven's Door on him, only to be given gibberish.
- Funny Valentine: There are two. The original Funny Valentine with D4C (although never introduced), and a Funny Valentine that has a Stand named Singing in the Rain (SINGING IN THE RAIN（雨に唄えば） Ame ni Utaeba), which allows him to fly. Both were Presidents of the United States.
- Funnier Valentine (ファニアー・ヴァレンタイン Faniā Varentain): One of the above Funnys' son. He is an astronaut and is 50 years old. His Stand Rear Window (リアウィンドウ（裏窓） Ria Windō), allows him to teleport from location to location and through dimensions.
- The Funniest Valentine (ザ・ファニエスト・ヴァレンタイン Za Faniesuto Varentain): Funniest has D4C for a Stand, but it doesn't make him immune to dying if he meets an alternate version of himself.

- Prosciutto Cappano (プロシュート・ケッパーノ Puroshūto Keppāno): Alternate universe version of Prosciutto. Strangely, the rest of La Squadra never shows up. Prosciutto is one of Cioccolata's assistants. His Stand Twister (ツイスター Tsuisutā) is the same as The Grateful Dead but with a cyclone/spiral theme on its body instead of multiple eyes.
- Pocoloco Tripleseven (ポコロコ・トリプルセブン Pokoroko Toripurusebun): Alternate universe version of Pocoloco. He is a black youth and also an astronaut. His Stand Right Stuff (ライトスタッフ Raito Sutaffu) is a group of semi-robotic humans that will do whatever it takes to complete a mission.

Aside from the above, we know that...
- The 36 Kars living on Mars are presumably the 36 souls of sinners that DIO required for his plan to reach Heaven. When Jorge draws a picture of Kars on his stomach, they form a bridge to reach the Dio described below.
- The DIO of Part 3 was not the real Dio Brando; Phantom Blood Dio Brando becomes the Ultimate Life Form and merges with the 36 versions of Tusk to become a monster. This Dio gained the Stand "The Passion", which resembles Jesus Christ; The Passion allows Dio the ability to predict his opponent's attacks.
- The corpse parts of Steel Ball Run are of his or another Dio's corpse, which Jonathan Joestar soon combines with after being resurrected and also gains "The Passion".
- Morioh Town and Passione's island headquarters both suddenly sprouts legs from its foundations and splits from the mainland, walking the earth. They eventually encounter one another, which is how the heroes all meet up.
- One version of Giorno Giovanna is now host to Diavolo as an alternate personality, as that Diavolo was a renegade Stand in similar vein to Anubis. As a result, the Doppio from that universe became a separate entity with his own Stand, one capable of transforming objects into telephones (which, according to pictures, is no different from what Universe J's Doppio did to communicate with Diavolo), but it's unknown if he remained Passione's underboss in that universe or was replaced by the Diavolo-possessed Giorno.
- Out of the 36 Diavolos, only two seem to survive: the above Diavolo, and the Universe J-Diavolo, who is still suffering from the effects of Gold Experience Requiem. Supposedly, others exist, but due to King Crimson, only the Diavolos that never split from Doppio suffer the endless fate.
- Santana is actually very brutal and no different from his comrades, being only passive due to flesh buds Kars implanted that worked similar to DIO's.
- At least one version of Yoshikage Kira has fallen for Lisa Lisa, intending on making her another "girlfriend". In order to win her affection, he begins calling himself "Kira Kira" and eventually succeeds in killing her by using the Golden Rectangle and a rope, which bisects her in an explosion with similar power to Killer Queen's regular bomb due to Made In Heaven. He then proceeds to dance with her corpse.
- As Erina and George II move to the Canary Islands, he is renamed "Jorge", the Spanish equivalent of "George", despite its completely different pronunciation in Spanish ("Hor-Hay").
- As far as JoJo's Bizarre Adventure goes, the JORGE JOESTAR novel is the most bizarre in terms of events that don't make that much sense to the manga's canon.
- A translation project or two are underway, but pictures from the book can be found here. The odd-numbered chapters are the ones featuring Jorge and Elizabeth growing up, the other tabs are everything else.
