History Heartwarming / JoJosBizarreAdventureDiamondIsUnbreakable

** A meta moment of heartwarming: Numerous times Josuke has displayed a surprising amount of cunning and cleverness. The same cleverness that Joseph showed back in ''Battle Tendency'' and ''Stardust Crusaders.'' Looks like he's a bit more like his father than we thought.

* In a {{Meta}} way, some fans of the series have really related to Okuyasu due to their own experiences with AbusiveParents, and it's heartwarming/motivating to see him step out of his family's shadow and find TrueCompanions who treat him with respect.

-->-- '''Jotaro Kujo''' to Josuke about the [[CombatMedic wonderful power]] of Crazy Diamond.

* As a whole, ''Diamond Is Unbreakable'' foregoes the adventure aspects of the previous parts in favor of something more at home with SliceOfLife stories, so while stakes are still high with all the crazy stand users around Morioh, a number of episodes are dedicated to Josuke and his friends just being teens and being able to have some fun. Despite the supernatural aspects of these SliceOfLife stories such as the visit to Tonio's and the plan to make money off of lost change and lottery tickets, it's rather heartwarming to see that Josuke is still able to just take it easy and enjoy life given how intense the overall franchise is.

* During the Stray Cat arc, the titular character attacks Shinobu and Kira (who has taken her husband's identity) moves to protect her, declaring "[[DeclarationOfProtection I won't let you harm her anymore.]] I'll make you ''disappear!''" and holding her in his arms. Later on one of Stray Cat's air bubbles strikes a cactus and causes it to explode, showering them both with cactus needles and Kira worries if Shinobu's eyes were injured.

* The ending of the anime has ''every previous singer who has performed for an opening'', from [[Manga/JoJosBizarreAdventurePhantomBlood Sono Chi No Sadame's]] Tominaga "TOMMY" Hiroaki to the current [[Manga/JoJosBizarreAdventureDiamondIsUnbreakable Great Days's]] Karen Aoki and Daisuke Hasegawa, come together as JO☆UNITED to sing [[https://www.youtube.com/watch?v=QqDxUPrNgZw one last grand rendition of Great Days]].

* Despite the antagonism between them, Josuke comes to Rohan’s aid in the Highway Star arc and makes sure he’s safe afterwards, with the manga version even noting that Josuke hopes that the incident will help put said antagonism behind them, even if Rohan is too stubborn to do so.

* Josuke meeting Joseph, especially in the anime with the fitting music. In spite of his initial reluctance of meeting him due to thinking that both of them will be strangers to each others, it's quite clear that Josuke is quite nervous around his father, much more so than he normally is when meeting new people. [[{{Adorkable}} It reaches a new level of heartwarming as he shyly takes Joseph's hand and helps him to walk when the latter's walking came broke when he could have used Crazy Diamond to fix it.]] (In the anime, Josuke is even [[LuminescentBlush blushing]] and trying not to cry, and the swelling orchestral music just makes it all the more touching.) Koichi actually sheds TenderTears at the father/son moment and even asks Okuyasu not to have Josuke fix Joseph's cane, to avoid spoiling it.

* When Tamashi steals Koichi's money, Josuke and Okuyasu don't hesitate to back Koichi up.
