Cool Shock Old B.T. was first published on October 19, 2021. It was initially a one-shot chapter published in Ultra Jump November 2021, but its popularity incited a sequel chapter that will release in the Winter 2023 issue of JOJO magazine on December 19, 2023 for Cool Shock B.T.'s 40th anniversary.[2]
In his car filled with JoJo's Bizarre Adventure collectibles, elderly B.T. is introduced by his best friend Koichi Mugikari. Koichi recounts how he got scammed out of his home and life savings by "The Outlaw Guys" company. They exploited his status as an author, flattered him, and tricked him into believing his house violated building codes. They sold him a shoddy villa in the suburbs of Morioh for 70 million yen, leading Koichi's son and grandkids to cut ties. When B.T. asks why the crooks referred to Koichi as "sensei", Koichi reminds him that Rohan Kishibe once designed a book cover for his novel based on B.T.
B.T. deduces the scam involved switching homes during the villa tour using structure relocation. They swapped the house with an empty one at Boyoyoing Cape and then returned it after showing the tour to Koichi. Although the police didn't intervene due to the scam involving a legitimate contract, B.T. and Koichi hatch a plan to find the scammers. They fake a video on J-Tube, with the help of B.T.'s affluent wife from London, who ships them diamonds. Koichi pretends to be wealthy in the video, claiming he found the diamonds in his villa's furniture.
Lured, the scammers meet them, and B.T., using his drama skills, dresses Koichi as a king and himself as a butler. They feign poisoning the scammers to extract information, though it's just sleeping pills. The Outlaw Guys' boss, Manabu, is aware of their approach, but B.T. and Koichi suddenly crash into his building. Manabu reveals that he already sold Koichi's house, but offers to buy it back since he still has the contract. However, he will only do so if B.T. can beat him in a game, otherwise he will take B.T.'s vintage car. Manabu challenges B.T. to a coin game, but B.T. asks to change the rules, suggesting that they decide the winner based on whether the difference between heads and tails will be an odd or even number. Both parties secretly use an extra coin to manipulate results. Yet, B.T. and Koichi outsmart Manabu and win the bet. Furious, Manabu charges toward B.T. with a sword, but is defeated by the scammers' self-driving car, which B.T. had hacked to target humans. Koichi recounts how they discovered the Outlaw Guys' hideout through the car's navigation history. Manabu and his gang are sent to a police hospital using the car. While the duo find Koichi's home contract in Manabu's safe, it would take time before Koichi could buy his house back. Koichi is invited to stay over at B.T.'s place but they must walk due to the tire of B.T.'s car being punctured by Manabu's sword. Despite B.T.'s mischievous ways, Koichi cherishes their bond.

Page 5: The "Do Not Enter" signs with Koichi in between them are the same as the signs on the Nijimura house’s gates (DU Chapter 10).
Page 7: The title card is in the same style as in CSBT Chapter 2. A lock can be seen on the side of the car. B.T. had various locks in his room in CSBT Chapter 5.

Page 8: The pamphlets contain quotes from DIO and Yoshikage Kira. The pamphlet with Kira's quote also has Stray Cat drawn on it.

Page 9:Coco Jumbo is visible in B.T.'s car, as well as a tribal mask, a miniature guillotine, a knife, a bottle with fishes, and several other bottles appearing in B.T.'s room in CSBT Chapter 5. Koichi mentions that Rohan Kishibe drew the cover of his book, a novel version of the original Cool Shock B.T. stories.
Page 11: The estate is located in the suburbs of Morioh.
Page 12: The SFX and B.T. say Ta-dah! (ドジャーン, Dojyaaa~~n!). This SFX first appears in CSBT Chapter 1 and is often used in its later chapters as well. Several years later, it became well known as the catchphrase of Funny Valentine from Steel Ball Run.
Page 12: A Stray Cat figure is visible on the board of the car.
Page 13: Koichi says "It’s been quite a cool shock to be blocked by my family", name-dropping the English title of the series.
Page 15: Koichi asks why his house became a Mansion Ghost, which is a specific phenomenon from Deadman's Questions.
Page 16: B.T. says it was an equivalent exchange between houses, referencing the Wall Eyes from JoJolion.
Page 18: B.T. says his catchphrase from Cool Shock B.T.
Page 19: The SFX says Toruru (トゥルル) when the phone rings, referencing Doppio mimicking a phone ringing in Vento Aureo. One girl is wearing a hat resembling the head of Echoes ACT3 from Diamond is Unbreakable. The door has a sign that says “Burnable Trash Pickup – Monday, Wednesday, Friday” referencing the defeat of Cioccolata and Secco.
Page 20: The boss of the Outlaw Guys appears as a silhouette and is called "Boss" in English by those who work for him, much like the Boss of Passione in Vento Aureo.
Page 21: A comment on the video of Koichi states "I want to be like him!" referencing the quote of the two brats admiring Dio in Phantom Blood. Another comment says Gorgeous ★ Old Man referencing Gorgeous ★ Irene. Koichi shows the jewel he's acquired at the end of CSBT Chapter 5.
Page 21: The composition of the scene mimics a composition that Araki commonly uses when characters are shocked or afraid throughout JoJo, with their faces appearing in the foreground on the sides of the panel.
Page 22: J-Tube is a parody of YouTube, with the J possibly standing for JoJo. The channel is called “UJ Treasure Discovery Channel”, with UJ possibly referring to Ultra Jump.

Page 22: Koichi says that he's scared about how many views the video is getting but B.T. claims that what they’re doing is fun. This is a callback to CSBT Chapter 5 when Koichi is scared about stealing from the museum and B.T. says the same thing.
Page 23: B.T. uses oriental medicine from London, which references the Oriental PoisonDio was buying to poison George Joestar I. Him saying he plans to live until the age of 183 is a reference to Wang Chan's claim that he's seen a man with ear birthmarks live until that age.
Page 24: Figures of Clyde and the Derringer from "Say Hello to Virginia" are visible.

B.T. is said to be a former drama club member, which is a callback to CSBT Chapter 3.
Page 26: The female scammer angrily says "Mukadotama! (ムカドタマ)" in her thoughts. This is a word that Araki made up to portray anger. Ninomori says it in CSBT Chapter 3. B.T. comes with Shinobu Kawajiri's prized tea set. A panel is drawn in the same style as Tohth.
Page 27: The rusty blade B.T. holds resembles the broken edge of Anubis that ends up at the bottom of the Nile, as it would appear after years underwater. He intimidates the scammer with it like how he intimidated a corrupt police officer with a knife in CSBT Chapter 0.
Page 29: B.T. calls himself a knight and says that the scammer is psychologically on a different level than him. This is a callback to CSBT Chapter 2 when he says the same thing except says he’s a noble instead of a knight. Koichi says "OH MY GOD!", the catchphrase of Joseph Joestar.
Page 30: The ringtone SFX of the phones reference Doppio's "Toruru" again. A sign on the left says "Concentration Camp (強制捕虜収容所)", referencing CSBT Chapter 4.

Page 32: The car crashing into the hideout resembles the panel of Wilson Phillips running over civilians.
Page 34: A note behind Manabu says FE26789, which is Miraschon's prisoner number. A letter behind Manabu on the table says "Don’t call a lawyer!! (弁護士を呼ばせるな！！)". This is a parody of Jolyne saying "Call me a lawyer! (弁護士を呼べェェーッ！！)".
Page 35: Manabu says B.T.'s brain turned to mush (encephalomalacia), referencing what Empress said to Joseph in the Weekly Shonen Jump release of SC Chapter 36.
Page 35: B.T. sarcastically calls Manabu a ripple warrior because Lisa Lisa slowed down her aging with her ripple abilities. His "Quit acting like you’re some big shot" is a quote that Jotaro says to the Impostor Captain Tennille. Manabu saying he owns slaves is a callback to him saying Koichi's family members were his slaves in CSBT Chapter 6.
Page 38: B.T. quotes Dio and Giorno's signature phrase of "Useless, Useless".
Page 39: Manabu offers to make a bet and B.T. replies the same way he did when they were kids.
Page 40: B.T. accepts Manabu's challenge in the same way as Rohan's "I refuse" panel although he says "I accept".

Page 41: Manabu takes on Shigekiyo Yangu's grin, while mentioning how an old lady "harvested" all the coins he took from her.
Page 42: B.T. holds the coins like he does in the series' cover artwork. He also mentions how he bets on an odd number not based on coincidence, but on bizareness. This is also a play on the Japanese words for even and odd numbers.
Page 42: The SFX on the Koichi panel is the same as the "Pressure" SFX when Josuke is hunting Bug-Eaten.
Page 44: B.T. palming a coin is a reference to him tricking Ninomori in CSBT Chapter 0. Koichi saying "And yet this guy wanted to prevent cheating? What a scoundrel!" is a reference to Jotaro realizing that Joseph was cheating against D'Arby.
Page 45: Manabu thinks the same thing about B.T. that Joseph says to Kars. Although they're good at tricking people, they can also be deceived themselves.
Page 47: Manabu quotes ZZ's "I win! Part 3 is over!" when he thinks he won the game. The panel showing heads and tails resembles Atum's power when reading Jotaro's mind. Manabu unsheathes a sword the same way he took out a knife when he was younger to throw at B.T.
Page 48: Manabu is tricked into being run over by a car again. Likewise, his sword misses B.T.
Page 49: The posters on the police station parody DIO's quotes on them. B.T. being glad that Koichi knew what he was thinking without any signals is a reference to Jotaro and Joseph's conversation after beating Telence T. D'Arby.
Page 51: Koichi's narration is the same as his narration at the end of CSBT Chapter 4. Manabu has the same expression as in the end of CSBT Chapter 6. A "To be Continued" arrow is shown. The last line is a parody of Diamond is Unbreakable.
This was fun! Many thanks to Araki-sensei and Demizu-sensei! (Nisio Isin)
Thank you for this wonderful opportunity! I'd also like to try to draw B.T. as a kid someday! (Posuka Demizu)
