The story is posted on [=AO3=] and can be found [[https://archiveofourown.org/works/23989186/chapters/57705622 here]]. The WhatIf story where Joker is sent to the VideoGame/NierAutomata verse alone without Morgana can be found [[https://archiveofourown.org/works/46177657 here]].

* JackBauerInterrogationTechnique: Once Joker finds out that Giran has been working for the League of Villains, he proceeds to have Seth and Cerberus rough him up quite a lot, and then have Pixie scare the crap out of him by threatening to basically nuke him out of existence with Megidolaon, or worse, just nuke parts of his body and have Joker continuously heal him in order to torture him. But considering what Giran's been involved with, this is easily a good example of KickTheSonOfABitch.

* NoodleIncident:
-->'''Akira:''' Oh yeah? What about that time—\\
'''Morgana:''' Sh-Shush! We don't talk about ''that time'' ever!

* HealingMagicIsTheHardest: Healing quirks are rare and highly sought after but they could only do so much. SMT/Persona Healing skills however can heal anything in the Quirkverse whereas those spells can't heal debilitating wounds back home. As a result, Joker and Mona are highly sought after for their healing powers alone because, from what everyone can see, the heroes who were healed experienced no side effects whatsoever, which is something the Thieves have no idea about and shrug off as something they can easily do in this world.

** Aizawa knows something wrong happened when he erased Kohryu, which resulted in a big headache for him and a [[HeroicRROD three-day coma for Joker]]. He understandably is horrified when Arsène angrily tells him what he nearly did to Joker that night.
** Ryukyu and some other heroes "defeat" Seth, but the resulting collateral damage and their overzealous hunt of Joker cause the local civilians to angrily protest against them, shaking her to the core.

* SneezeCut: When Hitoshi notes in the epilogue that Joker would be proud, the final scene opens with Ren sneezing.

* HeroicNeutral: Joker and Mona are only in it to help people because they won't be in this world for too long before returning home. Their only aims while trapped is to disrupt society and point out societal problems so that the people and government will be forced to look at them with fresh eyes. They have no horse in this race and looked at this new world with the perspective of their own world in mind, seeing striking similarities and outright HistoryRepeats. Joker and Mona knew full well that the people here expect them to heal them or their loved ones, expecting to solve their problems as the people did in their world.

* HomeBase: Kaito’s Internet cafe Raven’s Nest was the Thieves’ hideout; Gentle and La Brava used to stay at Gentle’s apartment before moving into the cafe to stay closer to Joker. After Kamino, Magne’s bar served as a temporary hideout before going to UA.

* KarmicDeath: All For One. When he got up again and once again KickTheDog, Joker refused to stand down and summoned Sraosha who ultimately killed him. After all that work to defeat Joker and the implied canon plans still in place, he and his quirk, both original and copy, felled by a Bless spell and the remaining Humanity’s Hope, wiping it off into the ether, unable to be revived as a Nomu or anything to revive him because he nor his quirk exists on this plane of existence no more.

* LifesWorkRuined: Joker and Mona's dismantlement of [[spoiler: the League of Villains. Due to All For One's single-minded effort to take Joker to steal his power, he sealed his fate as Sraosha murdered his soul and released the stolen quirks back to their rightful owners while others passed on, meaning Shigaraki will never receive the All For One quirk as both the original and duplicate are connected through the sheer fact Search is with the original while it was the copy that was used to steal Search. Joker also took over what the League wanted to do including the CriminalFoundFamily factor that the League of Villain's would have in canon, meaning the League has no grounds to exist on, not when Shigaraki is stagnating with no goals. Garaki hasn't even tested the High-End Nomus yet the League is falling apart by the seams.]]

* LonelyFuneral: All Might was the one who made certain [[spoiler:All For One]] was truly gone in cremation and buried with no name, burying the urn himself and not letting it rot in evidence as Kunikazu planned. [[spoiler:It’s unlikely Garaki was able to get the body in any way as it was protected heavily in Kamino, and no matter the reputation it would be hard for him to even get in there when he’s well known and why he wanted the body. Not that he can as he’s been hiding from the public since the Sapporo lab raid meaning the victims can easily identify him, including Joker and Spinner.]]

* NoGoodDeedGoesUnpunished: Continuing Joker's streak of abysmal luck, he wakes up in the middle of a wide-scale battle and tries to help as many people as he can. It doesn't go over well, since his outfit is rather suspicious, and results in many of the heroes mistaking him for a villain, culminating in Snipe ''shooting'' him.

** The Persona cast plays this straight. Ren has no hint of preferring anyone and neither do the other Phantom Thieves show themselves to be romantically inclined to someone. JustifiedTrope as the thieves had serious things to worry about (Yaldabaoth, being separated into different worlds and had to find a way to get back home and stop the Demiurge for good).
