History DealWithTheDevil / AnimeAndManga

** [[spoiler:Thief King Bakura's teaming up with Zorc to release him.]]

* The creation of the flame man in ''MermaidMelodyPichiPichiPitch'' turned out to be from such a deal. He was originally [[spoiler:a human that had fallen in love with a weak Panthalassa that had managed to escape the seal. [[TheManBehindTheMan Fuku-chan]] offered him a way to save his daughter, who had inherited the weakness in body after her mother died. Michal became Michel's mana battery, and her father became the flame pillar, the apparent authority actually ruled by Fuku.]]

* In ''ChronoCrusade'', demons need a type of spiritual energy called astral energy to use their powers and survive. Typically they use their horns to siphon the energy from their surroundings, but when a demon's horns are broken or for some other reason they need to augment their intake, demons can make a contract with a human. The demon serves the human they make the contract with, in exchange for the demon being able to drain their soul in place of astral energy, shortening the human's lifespan drastically. Most of the demons who make contracts in the series follow the typical archetype of being tricksters, but the title character subverts this. He makes a contract with Rosette, a nun, so that he is able to use his powers to help her save his brother, both of whom had befriended him. Throughout the series Chrono questions his decision to make the contract, causing quite a lot of his angstier moments.

* In ''DGrayMan'', [[BigBad the Earl of the Millennium]] promises his victims to bring back to life the person they have lost. He creates a metal skeleton and makes the victim call the name of the one he wants to come back. Then, the skeleton kills the victim and wears his skin, creating a monster, an "akuma".

* In ''MahouSenseiNegima'', BigBad Fate Averruncus offers Negi a deal, but manages to word it in a way that if Negi had accepted it, Negi would have been magically bound to keep his end of the bargain while Fate would not.

* In ''YamiNoMatsuei'', the Shinigami have to go to the rescue of a boy receives a cornea transplant that results in him taking on the burden of the previous owner's deal with a demon.

* In ''VisualNovel/UminekoNoNakuKoroNi'', a deal with the ''Endless Witch'', Beatrice, sets a large portion of the plot into motion.
* In one ''UruseiYatsura'' episode, Ataru Moroboshi manages to fulfill all the complicated conditions to make a pact with a demon COMPLETELY BY ACCIDENT!

* The Behelits from ''{{Berserk}}'' are a means to summon the Godhand, four evil demonic gods who offer their bearers the chance to become demonic Apostles (or in the case of those bearing a Crimson Behelit such as Griffith, [[spoiler:a new member of the Godhand]]) in exchange for the sacrifice of those closest to them, who are transported to hell along with the one presented with the deal and marked with the Godhand's Brand of Sacrifice if the bearer should accept, at which point the monsters come out of the woodwork to eat them alive. They're particularly insidious because they are activated by their bearer hitting the DespairEventHorizon, making the bearer particularly receptive to the Godhand's offer.

* The anime ''Anime/HellGirl'' revolves around a demonic young girl who offers people the chance to instantly send one of their enemies to Hell -- although the price for this "service" is that the sender's ''own'' soul will also be sent to Hell after their death.

* 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.

** Thief King's teaming up with Zorc.

* 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 {{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 and Kyubey will eat their souls.]]
** In the final episode, [[spoiler: Madoka's solution is to wish to destroy all witches before they exist with her own hands. And she means all witches, past, present and future, in all possible worlds. This causes a loop where Kriemhild Gretchen, Madoka's witch form, is destroyed by Madoka herself. The resulting RealityBreakingParadox causes Madoka to [[RetGone cease to exist as a human]] and [[AbstractApotheosis become a goddess of hope for Magical Girls]]. Kyubey was screwed so badly he doesn't remember any of this, and would consider the old world physically impossible.]]

* In the 3rd OVA to ''FushigiYuugi'', a young girl named Mayo becomes the new Priestess of Suzaku, even though by all logic, she shouldn't be there. She has also become pregnant with the child Miaka had been carrying earlier in the series, and has Miaka's wedding ring. Taka [[spoiler: Tamahome]] goes into the book to gather the other Seishi, summon Suzaku, and set the universe to rights. Mayo enters the Shrine of Suzaku, and the golden statue in there starts talking to her, saying how Taka was really gathering the Seishi to rise up and kill Mayo. Fearing for her life, Mayo asks what she can do to fix this. "Suzaku" tells her to pray for the destruction of Konan, except for herself, Taka, and the baby, promising to keep them safe.

* In ''Manga/{{Holyland}}'' chapter 147 the Yazuka regular tempts Masaki with Yazuka assistance in dealing with the drug problem if he just joins up. Masaki refuses.

* 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 witches. The {{Faust}}ian references are numerous. [[spoiler: In the end they become what they fight against and Kyubey will eat their souls.]]
** In the final episode, [[spoiler: Madoka's solution is to wish to destroy all witches before they exist with her own hands. And she means all witches, past, present and future, in all possible worlds. This causes a loop where Kriemhild Gretchen, Madoka's witch form, is destroyed by Madoka herself. The resulting RealityBreakingParadox causes Madoka to [[RetGone cease to exist as a human]] and [[AbstractApotheosis become an ethereal being of hope for Magical Girls]]. Kyubey was screwed so badly he doesn't remember the old world.]]

* 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.]]

* Count D in {{PetShopOfHorrors}} pretty much is this trope. He will sell you "love, hope and dreams" provided that you keep to the contract. If not... things will go very badly for you. Since this is all a part of his [[GenocideBackfire revenge scheme against humanity]] for [[spoiler: eradicating [[LastOfHisKind almost his entire species]]]], often it seems as if the humans are set up to fail so they will learn their lesson and then die horribly - but there are also times when human nature surprises him.

* Witsarnemitea in the anime/VisualNovel ''{{Utawarerumono}}'' ''loves'' to grant 'wishes', particularly in the mysterious backstory. For instance, DO YOU WANT A STRONGER BODY? [[WhoWantsToLiveForever DO YOU WANT TO LIVE FOREVER?]] ENJOY [[spoiler:BEING TURNED INTO A RED JELLY]], ASSHOLE. DO YOU WANT TO LEARN MORE ABOUT ME, PHILOSOPHER? HOW ABOUT I [[spoiler:TAKE COMPLETE CONTROL OVER YOUR BODY FOR THE REST OF ETERNITY]], LOL. Sometimes you have to swear your entire being away in a contract in order to get help, though.

* ''AkumaNaEros'' has Satan as a BastardBoyfriend who agrees to help a girl named Miu to snatch the attention of the resident highschool heart-throb. But he demands her virginity as a payment, and is bent on collecting...

* In ''Manga/KamisamaKiss'' Tomoe made a deal with a Fallen God to become human in order to live out the rest of his life with the woman he loved, the catch being that the moment she died he died.

* 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 witches. The {{Faust}}ian references are numerous.
** And in the end [[spoiler: they become what they fight against.]] And Kyubey [[spoiler: will eat their souls.]]
** In the final episode, [[spoiler: Madoka's solution is to wish to destroy all witches before they exist with her own hands. And she means all witches, past, present and future, in all possible worlds. [[LogicBomb This causes a loop]] where Kriemhild Gretchen, Madoka's witch form, is destroyed by Madoka herself. The resulting RealityBreakingParadox causes Madoka to [[RetGone cease to exist as a human]] and [[AbstractApotheosis become an ethereal being of hope for Magical Girls]]. Kyubey was screwed so much, he doesn't even remember the old world.]]

** The shinigami can also offer a second deal, exchanging half of the user's remaining natural lifespan in exchange for [[EvilEye Shinigami eyes]], allowing the user to know the true name of whomever they look upon, [[YourDaysAreNumbered the exact date in time that they will die]]. The value of the second deal for the Shinigami isn't immediately apparent, but if a Shinigami lost their only note the deal could become the only way for them to extend their lifespan.

** In the final episode, [[spoiler: Madoka's solution is to wish to destroy all witches, past, present and future, in all possible worlds before they exist and with her own hands. [[LogicBomb This causes a loop]] where Kriemhild Gretchen, Madoka's witch form, is destroyed by Madoka herself. The resulting RealityBreakingParadox causes Madoka to [[RetGone cease to exist as a human]] and [[AbstractApotheosis become an ethereal being of hope for Magical Girls]].

** And in the end [[spoiler: they become what they fight against.]] Either way Kyubey [[spoiler: will eat their souls.]]
** Subverted when [[spoiler: Madoka wished to destroy all witches, past, present and future, before they exist. With her own hands. This caused a loop where Kriemhild Gretchen, Madoka's witch form, is destroyed by Madoka herself. Because of this, Madoka ceased to exist as a human and became an ethereal being of hope for Magical Girls. Kyubey was screwed so much, he doesn't remember.]] [[EpilepticTrees Unless that's what he wanted all along....]]

* In ''{{Dororo}}'', Hyakkimaru's back story involves his father striking a deal with 48 demons in exchange for political power. In exchange, each of the demons takes a part from his then-unborn son.

** Kaiser, with Saruyama. Once Hell Kaiser has the skill and victories he wants, he kicks Saruyama to the curb and goes off on his own. Saruyama is never seen again.

** In ''Anime/YuGiOhZexal'', this may or may not be an important part of the plot. In the beginning of the series, Yuma makes a deal with a demonic entity called simply "the Door". It says "Whoever opens this door will obtain a new power, but in exchange will lose what they appreciate the most." Yuma accepts this offer, and later meets Astral, gaining the ability to fight and control the Numbers. The Door appears later, giving Yuma the Zexal Power and this time saying that it will cost Yuma his most precious belonging. Still later, the Door tests Yuma, forcing him to battle a demon called the Shadow Giant; after Yuma is victorious, Astral gains another useful ability. It is not yet known what this being will eventually demand from Yuma, but clearly, this will remain a constant part of his career for at least the time being.

* In ''Manga/OnePiece'', this is probably where the name Devil Fruit comes from. If you eat it, it gives you power, but the seas abandon you (i.e., you suffer from SuperDrowningSkills).

* Count D in {{PetShopOfHorrors}} pretty much is this trope. He will sell you "love, hope and dreams" provided that you keep to the contract. If not... things will go very badly for you. Since this is all a part of his [[GenocideBackfire revenge scheme against humanity]] for [[spoiler: eradicating [[LastOfHisKind almost his entire species]]]], often it seems as if the humans are set up to fail so they will learn their lesson and then die horribly - but there are also times when human nature surprises him.

* In ''Manga/KamisamaKiss'' Tomoe made a deal with a Fallen God to become human in order to live out the rest of his life with the woman he loved, the catch being that the moment she died he died.

* In ''DragonBallZ'', during the Buu arc, Vegeta willingly allows Babidi to brainwash him for the power boost that comes with it so he can finally surpass Goku, and it's referred to as Vegeta "selling his soul". However Vegeta's desire to fight Goku allows him to completely ignore all of his new "master"'s orders, and Vegeta dies trying to destroy the monster Babidi unleashed, and it seems either his or Babidi's death released Vegeta from the mind control.
