History DealWithTheDevil / AnimeAndManga

** Decades ago, when Quirks first emerged, [[BigBad All For One]] helped people by taking away their undesirable Quirks or giving strong Quirks to people who needed them--in exchange for their loyalty. In his own words, he offered choice to the powerless and mercy to sinners as long as they joined him. In reality, All For One cared nothing for people. Instead he killed those who opposed his command and abandoned those who could no longer follow his command. Notably, this is why he calls himself a [[MaouTheDemonKing ''Demon'' Lord]] (that, aside from reading stories about that kind of character and wanting to do so in real life). He wants to create an anarchic hellscape where the only opportunity for power is to beg for it from the devil.

* Illegal Contractors in ''Manga/PandoraHearts'' make deals with "chains" from The Abyss to change their pasts or give them powers in the present. Oz is Alice's Illegal Contractor, although their whole situation is unique. [[spoiler:Break]] made a deal with the Will of the Abyss herself but the exact details have not yet been revealed.

* In ''Anime/UminekoWhenTheyCry'', a deal with the ''Endless Witch'', Beatrice, sets a large portion of the plot into motion.

** Prior to the Vandenreich's second invasion, Komamura meets with his great-grandfather and asks him to teach him their clan's [[DangerousForbiddenTechnique Humanization Technique]]. The elder eventually agrees in exchange for Komamura ripping out his own heart; Komamura does so without a shred of hesitation, and later pays the price for using the technique by permanently becoming a normal wolf.

* ''Manga/ChainsawMan'': Devils provide deals with a multitude of tiers and benefits. Souls and/or human lives aren't common currency and are far from the norm presented in the series as demons typically want immediate payment and few summoners are willing to enact deals that will just kill them right away with no benefit. However, there are three major wrinkles. Firstly, it's a seller's market; a demon can provide the same service to different people at drastically varying rates which range from huge swaths of their lifespans or just the use of certain organs and limbs. Secondly, a person doesn't necessarily have to pay the price themselves as they can just pluck whatever is required from people who they have authority over. Thirdly, there are no refunds should the service be rendered moot; if say, someone paid years of their life to kill an enemy with a devil's power, they will not get those years back if that enemy is revived by a third party.

* ''Manga/MyHeroAcademia'': Decades ago, when Quirks first emerged, [[BigBad All For One]] helped people by taking away their undesirable Quirks or giving strong Quirks to people who needed them- in exchange for their loyalty. In his own words, he offered choice to the powerless and mercy to sinners as long as they joined him. In reality, All For One cared nothing for people. Instead he killed those who opposed his command and abandoned those who could no longer follow his command. Chapter 336 reveals this is how he managed to infiltrate an inside agent in the UA: [[spoiler:Aoyama's parents, saddened at the ostracism their son endured for being Quirkless, had All For One give him his Navel Laser Quirk (explaining why his body can't endure it, he got it recently and thus his body hasn't adapted to it) in exchange for him giving the intel, thus leading to the USJ and Training Camp incidents]].

* In ''Manga/{{Naruto}}'', [[TheRival Sasuke]] makes a deal with [[BigBad Orochimaru]] -- in exchange for giving him the power to defeat his brother, Sasuke will allow Orochimaru to [[GrandTheftMe possess his body]]. [[spoiler:However, he merely learns all Orochimaru has to teach him, at which point Sasuke kills him. [[NotQuiteDead Only, not really]], as Orochimaru comes back as TheVirus.]] Subverted in that Orochimaru didn't intend to honor the deal [[spoiler:either]] and was going to possess him the moment he arrived. TheHero's FiveManBand (well, TheSmartGuy's FiveManBand) managed to delay the QuirkyMinibossSquad delivering him long enough that a substitute had to be used and [[TimeSkip bought everybody three years.]]

* ''Manga/{{Bleach}}'': Yhwach thrives on people looking to him to become stronger by curing their problems and granting their wishes. He cures ailments, missing limbs and voids of the soul by inserting a piece of his own soul into them. This drastically reduces the person's lifespan as the soul fragment is designed to obtain a power-up from residing in the victim to strengthen Yhwach when it returns to him.

** Subverted with Vanessa's bargain with the Witch Queen. After returning to the Forest of Witches, Vanessa asks the Queen to heal Asta's arms in exchange for her freedom. However, the Queen turns on Vanessa and her friends, and she reveals that she knew her daughter would return to the forest after all. Fortunately, the Queen ultimately keeps her word after she's completely defeated by the newly-manifested Red Thread of Fate.

** ''[[GateOfTruth The Gate]]''. It will give you a lot, especially knowledge with which you will have extreme power over the physical world, but it will take 'something of equivalent value' in exchange, and it will make sure that that is the most ironically painful thing it could take. 'Equivalent Exchange' is the catch phrase, but look at that shit-eating grin on Truth Guy: in this universe, '''God exists, and he is a total dick.''' So...Ed is a witch, but it's okay because God and the Devil are one? Eventually, he finds the back door, too...but he still has to give up a lot.

* In ''Anime/PuellaMagiMadokaMagica'', Kyubey offers to grant the girls any wish, in exchange for becoming a MagicalGirlWarrior and spending the rest of their lives fighting [[EldritchAbomination witches]]. The Myth/{{Faust}}ian references are numerous, although not always obvious (e.g. Mephistopheles being a RidiculouslyCuteCritter). [[spoiler: In the end they become what they fight against.]] Besides looks, the unusual thing about Kyubey in this context is that it's ObliviouslyEvil; while it has some idea of how to manipulate humans into accepting deals, it doesn't ''try'' to deal unfairly, it just [[BlueAndOrangeMorality doesn't understand]] how dealing fairly with humans would even work, and can't take seriously concerns that wouldn't concern a TotalitarianUtilitarian.

* This is essentially TheReveal explaining the plot in ''LightNovel/{{Baccano}}'': [[spoiler:the elixir of immortality and the recipe for creating it were given to Maiza by a "demon" he called up. Unusually for the trope, the demon doesn't really make a specific demand in return; his payoff is watching all the chaos that results from the deal; and an infinite amount of intelligence, experiences and 'wisdom' - Received from any immortal who comes to him to die, if they don't want to live any longer, since the method of killing an immortal also gives their memories and information to the killer. Ronnie, the 'demon', is in fact a two-thousand year old homunculus clone of a former self who was also considerably old. Because of this, he is very knowledgeable and relatively omniscient.]]

* In ''LightNovel/HighSchoolDXD'', demons such as the protagonists routinely form Contracts with humans to build their own influence and power. Contracts like [[LighterAndSofter modeling a cosplay outfit in exchange for some snacks]]. Demons are actively trying to get away from the your-soul-for-power negative PR after the GreatOffscreenWar hugely depopulated the race and left extinction as a very real threat. They can't afford to risk getting hunted down by Angels or church assassins just because bigger contracts are quicker.

* ''LightNovel/RebuildWorld'': Viola, a KnowledgeBroker with ChronicBackstabbingDisorder offers these all of the time, always selling people information or services that come back to bite them, and she actually has a reputation for it. She asks for money, while convincing someone to take an action that will lead to their demise, as part of PlayingBothSides typically. An example of Viola's deals, is her selling Inabe a valuable relic in secret he can plant in his domain to increase investments in it, while selling that he's doing that to Inabe's political rival who can now call in investigators to expose Inabe and take him down. In that case it was also a XanatosGambit because whoever won that confrontation, she had ties with, and when it blows up on Inabe’s rival due to a SpannerInTheWorks, Inabe thinks that was part of her plan.

* In at least the anime of ''LightNovel/{{Slayers}}'', [[BlackMagicianGirl Lina Inverse]] was offered this during the Gaav/Phibrizo story arc. Various deals with the Mazoku exist in Slayers canon. One option is the "Pledge of Immortality", where the human becomes immortal and invulnerable as long as they serve the Mazoku. One signatory of such a deal was Halcyform the White, a wizard from Atlas City.

* ''Franchise/{{Digimon}}'':
** [[spoiler:Impmon]] in ''Anime/DigimonTamers'', who was allowed to evolve in exchange for his servitude. Ironically, he's a devil-themed Digimon striking a deal with a Digimon god. Even more impressive in that you consider his deal is with Caturamon, who shares his English voice with Devimon, Devidramon, and [=MarineDevimon=].
** [[{{Mephistopheles}} Phelesmon]] in ''Anime/DigimonGhostGame'' is a BigRedDevil Digimon who's known for these. When he materializes in the real world, he acts as a FortuneTeller telling young girls how they can achieve whatever they desire, only to [[LotusEaterMachine terrorize them with illusions]] before [[TakenForGranite turning them to stone]].
