A dramatically-made promise that serves as {{foreshadowing}}. The promise will eventually be called in and action will be [[BeCarefulWhatYouSay required.]]

Whether they [[IGaveMyWord succeed]], [[FailureKnight fail]] or [[TheOathBreaker refuse]] to keep their promise depends almost entirely on the [[SlidingScaleOfIdealismVersusCynicism idealism-level]] of the story. Other factors, such as whether they were told what they had to do, or if it was a LeonineContract, may come into play. Even ReleasingFromThePromise is usually a scene of high drama.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* This is basically the trope that sets in motion Mashiro's persistence to become a mangaka in ''Manga/{{Bakuman}}''. A promise made in Chapter 1 between him and Azuki,that when he and Takagi get an anime from their manga and Azuki voice-acts the heroine, she and Mashiro will get married.
* Utena invokes ThePromise in her vow to save Anthy in ''RevolutionaryGirlUtena''. [[spoiler: Even when she ultimately fails, her valiant attempt leads to Anthy freeing herself to go in search of her fallen hero(ine).]]
* ''Manga/{{Bleach}}'':
** In the Soul Society arc, Ichigo ''will'' save Rukia... whether she likes it or not.
** During the Arrancar Arc, Ichigo vows to Orihime that "next time... I'll definitely protect you!" Later, he tells her "Don't worry. I'm definitely going to win." This promise is so strong that when Ulquiorra brings him to the verge of death, he is resurrected as an insanely powerful hollow obsessed with protecting Orihime - and ''only'' Orihime.
* Keitaro holds strongly to his 15-year-old promise to get into Tokyo University for/with a nearly-forgotten girl in ''LoveHina''. He also made a similar promise to forever be with his adoptive sister, which she does indeed dramatically call him on in the {{OVA}} sequel, ''Love Hina Again''. The concept of promises also is the main theme of the episode about the RobotGirl Moe.
* Both Lottie and Sara in ''SoukouNoStrain'' promised to become Reasoners and see their brothers again. [[spoiler:One brother kills the other before either can reunite.]]
* In ''Anime/PokemonLucarioAndTheMysteryOfMew'', when Ash tries to console Lucario after it believes it was abandoned and asks if he can help, it only wants him to do one thing: Promise he will ''never'' abandon Pikachu. Ash swears he will not.
* In ''RanmaOneHalf'', these promises cropping up out of nowhere are common plot elements - Ukyo has at least two with Ranma, Kodachi has one with her rival Asuka, and Ranma has several that he doesn't even know about until they're called.
* ''Manga/{{Naruto}}'' is full of "promises of a lifetime"... some more successfully fulfilled than others. The most notable case is Naruto's promise to Sakura to return with Sasuke. [[spoiler:The episode after the mission to do this was actually called "The Promise That Could Not Be Kept." Though, he renews his promise and it's still his most important reason to fight, alongside protecting his friends.]]
** Another plot relevant promise is Sasuke promising to avenge his family by killing his brother. [[spoiler: Once he succeeds he instantly makes a new one: Destroying Konoha. Obviously that guy needs someone to kill.]]
** Kakashi promised Obito that he would look after Rin. It would seem he failed. [[spoiler: The NotQuiteDead Obito witnesses Kakashi actually killing Rin, contributing to his change into Tobi]]
* ''{{Vandread}}'''s Hibiki made the casual promise to come to Dita's room. Though hardly a big thing to promise, this haunts him throughout the entire second season.
** They way they talk about it makes it seem like something else...
* In the Battle City arc of ''Anime/YuGiOh'', Jounouchi's/Joey's major motivation is his promise to duel with Yugi and get back his Red-Eyes Black Dragon card.
* ''ElfenLied'' plays around with this in the scene where the villainous Bando, rescued by Mayu earlier in the series and feeling indebted, promises to save her once if she winds in trouble. Mayu is forced to cash in this promise not even a minute later, when ''Bando himself attacks her.''
** But when she calls for his help again, he shows up in minutes and knocks the stuffing out of the man [[spoiler:sexually assaulting her.]]
** A second example is [[spoiler: Kouta promising to meet Lucy back at the stone on the last day of the festival.]]
* In ''DigimonAdventure02'', Ken promises to Wormmon that he won't betray his essential nature -- in essence, that he'll stay kind and gentle -- when he first meets him as a child. Flash-forward to a few years, MoreThanMindControl, and some heavy psychological trauma later, however, and he's the Digimon Kaiser. [[spoiler:He does eventually keep his promise, though. Kinda.]]
** In the previous season, Takeru promises to Sora that he'd protect Hikari. A promise which he still takes rather seriously in DigimonAdventure02, as he is seen putting himself protectively in front of Hikari (episode 3), seemed angry at himself for accidentally leaving her stranded in the Digital World (episode 7), and doggedly searched for her when she was taken by the Dark Ocean (episode 13).
* A much darker version appears in ''TokyoBabylon''.
* ''VideoGame/SuperRobotWarsOriginalGeneration'' has this: Kyosuke made a promise to Lamia that he'd kill her if she ever loses her mind ("If you ever lose your mind, don't worry. I'll destroy you myself"). He did get his time to try and fulfill it when he rescued her from the Bartoll. He succeeded in the OAV, but horribly failed in OG Gaiden, and later has to leave it to [[spoiler:Axel]] to actually rescue her and restore her mind.
* And also included in ''[[MagicalGirlLyricalNanoha Magical Girl Lyrical Nanoha StrikerS]]'', though it may be a bit unimportant, considering it came in the last episode of the last season. After Signum beats Zest and gives him a honorable death, Agito prompts Signum to watch over her and see if Signum can really follow up Zest's last wishes and his ideals. Signum's response? "If you ever see me straying from that direction, kill me." More proof that Signum is a magnificent {{Expy}} of Lamia.
* ''GetBackers:'' Ban promised Yamato that he would protect Himiko from her curse, and Juubei promised to stop Kazuki if he ever strayed "from the path of righteousness."
* ''Manga/KatekyoHitmanReborn:'' Squalo promised 8 years ago to Xanxus that he will never cut his hair until Xanxus becomes the boss of Vongola. And he did, [[spoiler:for eighteen years into the alternate future from the Ten Years Bazooka]]. Obviously because [[spoiler:Xanxus doesn't have the blood of Vongola, thus it's impossible for him to become Boss]].
* ''PeacemakerKurogane:'' Tetsunosuke promised to his friend Saya that he would not kill.
* ''BloodPlus:'' Saya makes Haji promise [[spoiler:to kill her after she defeats Diva, a promise which he is unable to keep, instead encouraging her to live]].
* ''NabariNoOu:'' Miharu's promise to Yoite, made under duress, to [[spoiler:erase Yoite's existence once Miharu can use the Sinrabanshou]] becomes the main tension and plotline of the series, as well as a source of a lot of its angst.
* In ''Anime/{{Noir}}'', much drama is derived from Mireille's ill-considered promise to kill Kirika once she learns the nature of their past connection--by the time that occurs, the emotional bond between the two of them is so strong, Mireille finds herself unable to pull the trigger, even though [[spoiler:Kirika turns to have been single-handedly responsible for everything bad that has ever happened in Mireille's life and actually ''begs'' Mireille to kill her, unable to live with the guilt]].
* ''Anime/{{Madlax}}'' has Madlax and Vanessa promising each other to survive. [[spoiler:It looks like Vanessa fails, but along comes [[RealityWarper Margaret]] ex machina...]]
* ''ThePlacePromisedInOurEarlyDays'' has such a promise as the entire backbone of it's plot.
* ''Anime/YuGiOhGX'': At the last second in season three, it is revealed that in their past life together, Juudai promised that he would love only Yubel forever. This became the driving force of their motivation when they returned in season three. [[FridgeHorror Then one remembers that Yubel can freely alter people's memories, and has no moral compunctions that would prevent their from using these powers to get their way...]]
** And then one remembers that their souls fused and any lies on either side would've been known and that Yubel didn't know that Juudai had remembered their past together. Yubel had nothing to do with his memories reviving. That happened because he'd actually inflicted damage on Yubel, which almost no one can do, since Yubel's effect is to take no battle damage at all. Not to mention that if Yubel lied, it would've been a part of the plot. Juudai loves Yubel. Their past is not a lie.
* [[MahouSenseiNegima Negi]] promises Ako that he will win the tournament. At about the ten second count, he recalls the promise and gets up to face Rakan once more. [[spoiler:It's actually at tie and Rakan ''could'' have beaten him if he really wanted to. But considering the shape Negi was in? Badass.]]
* ''ChronoCrusade'' has several promises that the main characters take very seriously. The first is that [[spoiler:[[PosthumousCharacter Mary Magdalene]]]] made Chrono promise to "live", which is implied to be the only reason he [[spoiler:didn't commit suicide after her death]]. Also, the manga version shows Joshua and Rosette promise as children to [[spoiler:"grow-up together"--remembering his promise is what gives Joshua the strength to reject Chrono's horns]]. Also, when Rosette made [[DealWithTheDevil her contract with Chrono]], Chrono seems to have promised ''himself'' that he would protect her, even going to the point of saying he promised to "never make her cry" in the manga. When he's forced to break this promise at one point, he becomes [[UnstoppableRage really pissed]].
* In ''Manga/TheSecretAgreement'', Iori tells Yuuichi that he loves him more than anything and [[ExactWords would sacrifice anything for him]]. This is perfectly romantic until Kyuusai reveals to Yuuichi that he is born to steal life-energy and that his destined prey, under the delusion of love, will naturally [[HarsherInHindsight offer his life]] for him to take.
* In ''TigerAndBunny'', Kotetsu made a promise to his wife on her deathbed to continue to be a [[{{superhero}} Hero]] after she was gone. [[spoiler:This promise starts getting harder and harder to keep once Kotetsu starts losing his powers.]]
* In ''PonyoOnTheCliffByTheSea'',
** Sosuke's father doesn't make it home as he promised.
** Sosuke promised Ponyo to keep her safe, and she's swept away by the sea.
** Sosuke's mother promises she will come back; Sosuke and Ponyo set out in search of her when she doesn't.
* CodeGeass has several. A couple of them are found on the PinkySwear page and are explained in more detail there. A non-pinky promise comes during arguably the biggest CrowningMomentOfHeartwarming in the series; when [[MagnificentBastard Lelouch]] realizes how much his friends care about him, he [[ManlyTears tearfully]] promises them that he'll set off fireworks with them again someday. [[spoiler: He doesn't, and when he realises he won't be able to keep this promise, he calls them to apologize and say goodbye.]]
* In ''{{Gate 7}}'', Hana is [[IWillWaitForYou waiting for someone who has not been revealed yet]] and once they are reunited, they will keep their promise.
* In ''OnePiece'', a band of pirates left a baby whale they adopted named Laboon at the beginning of the Grand Line, promising to return after they've made the round-world voyage. Unfortunately, those pirates were wiped out, half becoming ill and having to leave the ship to save the rest, and those that remained were wiped out in a battle. Of those pirates, only Brook remains, having been brought [[CameBackWrong back to life as a skeleton]] by his Devil Fruit. And now he has promised to his dead crewmates to deliver the final message of the Rumbar Pirates to Laboon, even after fifty years.
** When the Straw Hat crew first met Laboon, the whale was battering himself to death on the Red Line out of despair of the unfulfilled promise, prompting Luffy to make a new one. He gets into a fight with Laboon which he declares a draw, stating they will have to have a rematch when he returns. Further, he paints his logo on Laboon's head as a mark of the promise, which would be earesed if Laboon returned to hammering at the Red Line.
** During their childhood, Luffy and Ace made one promise to each other [[spoiler:after the death of their third brother Sabo]]: they would live their lives free of regrets. [[spoiler:This promise is one of the major reasons why Luffy was able to move on from Ace's death and continue following his dream.]]
** Luffy and Zoro's goals can be seen as promises to Shanks and Kuina respectively.

[[folder:Ballads]]
* In the Literature/{{Child Ballad|s}} "Literature/TheLordOfLornAndTheFalseSteward",
** The steward promises to protect the young lord on his journeys, and promptly becomes TheOathBreaker.
-->''"If I be not true to my master," he said,\\
"Christ himselfe be not trew to mee!\\
If I be not true to my lord and master,\\
An ill death that I may die!"''
** The young lord saves his life by promising to never tell anyone about the steward's having attacked and robbed him. (He gets around this through ExactWords.)
** The duke's daughter the steward was wooing pretending to be the young lord, on learning the truth, promises to marry no one but the true lord.
-->''"If you doe not my councell keepe,\\
That I haue told you with good intent,\\
And if you doe it not well keepe,\\
Ffarwell! my life is at an ende."\\
"I wilbe true to thee, Lord of Learne,\\
Or else Christ be not soe vnto me;\\

[[folder:Fairy Tales]]
* In "Literature/{{Bearskin}}", the hero, appalling shaggy, filthy and ragged, but rich, rescues a man from financial distress, the man [[ThePromise promises]] that he may marry one of his daughters. Only [[YoungestChildWins the youngest]] is willing. However, his appearance stemmed from a DealWithTheDevil, and that being over, [[SheCleansUpNicely he cleans up nicely]] and formally arrives at their house as a wooer -- or, in some variants, at his own wedding.

-->''Every time she went along the street and met the ogress the old woman said to her, "Tell your mother to remember her promise." And she went on repeating this message so often that the poor mother, having no longer patience to listen to the refrain, said one day to Parsley, "If you meet the old woman as usual, and she reminds you of the hateful promise, answer her, 'Take it.'"''

She falls in love with the human who finds her, and agrees to marry him, on the condition that he not [[PeepingTom peek at her while she bathes]]. They are HappilyMarried for awhile, raising several children (all of whom are more like demons or demigods, depending on whom you ask), and settling into a nice chateau. Buut, one day, her hubby's curiosity and/or lust gets the better of him, and [[WhatAnIdiot he peeks in on her bathtime]], and finds out that she's actually a mermaid. (He sees her tail fin.) [[DoNotTauntCthulhu Melusine]] is ''not'' happy, to say the least.

In chapter 103, she asks a sick Ran to promise that she'll wait for her in the afterlife.

Except that his ''rigor mortis'' prevents him from fitting into the coffin. [[BlackComedy Why, look. A hacksaw.]]
* As of ''Discworld/{{Thud}}'', [[Literature/{{Discworld}} Sam Vimes]] reads the same book to his son at six o'clock, every day, no excuses (because when you have a good excuse, you open the door to bad excuses). As for [[CrowningMomentOfHeartwarming the one]] [[CrowningMomentOfAwesome moment]] he can't make it in time...
* In the ''SwordOfTruth'' series, it's mentioned several times that "A Wizard always keeps his promises." At one point, a secondary character tells the main character that the reason this happens is, as a wizard, he's subconsciously using his magic to make sure the promise is kept.
* In the novel ''[[AWizardInRhyme The Oathbound Wizard]]'' by Christopher Stasheff the wizard Matt Mantrell makes a careless hyperbolic vow to overthrow a nearby BigBad. Since he lives in a magical world with similar laws to Medieval legend, he is honor bound to do so. He later convinces God that the vow was made in error and he shouldn't be held to it, but by then he has seen how horrible the BigBad is and wants to overthrow him anyway.

She dislikes giving her word on principle -- then she has to [[IGaveMyWord keep it]] -- and so insists that he give his word too.
* In JamesSwallow's TabletopGame/{{Warhammer 40000}} ''[[Literature/BloodAngels Deus Encarmine]]'', Rafen complains of the [[RedemptionEqualsDeath killings]] because they have promised [[WouldNotShootACivilian to protect such people]].

When Coraline asks if her mother has a grave, the Other Mother says she put her there herself, and put her back when she crawled out. Coraline insists on something else, and the Other Mother swears by her strong right hand. [[spoiler:When she breaks it, she sends her hand after Coraline.]]
* [[OutboundFlight Jedi Knight Lorana Jinzler]], aware of her impending HeroicSacrifice, gets Jorj Car'das to promise to find her estranged brother, still working at the Jedi Temple, and tell him something.
--> "Just tell him that his sister was thinking of him, hoping that someday he'll be able to let go of his anger. His anger at me, at our parents, and at himself."
--> "All right. I'll do my best."
--> "You'd better go then. Please don't forget."
--> "I won't."
** Then Car'das neglects the promise for ''fifty years'', until SurvivorsQuest.
* In Creator/LewisCarroll's ''Literature/SylvieAndBruno'', a subject of discussion between Lady Muriel and the narrator.

* In ''Literature/TheSilmarillion'', Fëanor and his sons swore a terrible oath to recover the Silmarils at any cost. These Silmarils were three hallowed jewels which Fëanor made, and which [[BigBad Morgoth]] stole. Centuries later the oath destroyed them thoroughly, and resulted in them slaughtering many innocents. Even after the last two surviving sons [[TragicVillain thoroughly hated the oath and wished to stop killing people]] over the jewels, they felt (or thought they were) somehow compelled to continue.
** In ''Literature/TheLordOfTheRings'', Aragorn can summon the Dead to fulfill the oath of assistance that they did not respect centuries before.
** In ''Literature/TheLordOfTheRings'' this is the reason Sam remains with Frodo even with the rest of the Fellowship is scattered. He made a promise to Gandalf that he would not leave Frodo, and Sam is a hobbit of his word. He chases after Frodo's boat even though he can't swim, and nearly drowns rather than break the promise. Frodo helps Sam aboard and they continue to Mordor together.
* ''Literature/TheGodfather'': Don Vito Corleone basically operates by getting these from a great number of people. (The novel says that ''[[LampshadeHanging he piled up good deeds like a banker piles up securities.]]'') Interestingly, we never see him extort any ''criminal'' acts from the recipients of his "favors"; instead, he gets completely innocuous freebies from whatever their normal business is. (Wedding cakes from the baker, performances at his casino from the singer, and a funeral from the undertaker when [[spoiler: Sonny]] gets whacked.)

* In Creator/RobertEHoward's {{Kull}} story "The Shadow Kingdom", after Kull and Brule learn that the ghosts of those the Snakemen kill are [[MadeASlave their slaves]].
-->''A shudder shook Kull's gigantic frame. "Valka! But what a fate! Hark ye"—his fingers closed upon Brule's sinewy arm like steel—"hark ye! If I am wounded unto death by these foul monsters, swear that [[MercyKill ye will smite your sword through my breast lest my soul be enslaved]]."\\

It seems like a safe thing to do since it's a routine expedition and he wasn't planning to marry her until after he got back anyway. But then the nation they were going to trade with unexpectedly puts a trading embargo on the protagonist's city. And the god he swore by is real, interventionist, and quite willing to make the vow stick.
* The ''Literature/WarriorCats'' novel ''Crookedstar's Promise''. A mysterious spirit cat asks the main character, as a kit, to promise to be loyal to his Clan above all else, even his own desires. Naturally, he promises, since he can't imagine ''not'' being loyal. Turns out that she meant that he can't take a mate or anything of the sort, and she definitely didn't have his or the Clan's best intentions at heart.
* In Creator/EdgarRiceBurroughs's ''Literature/TheMonsterMen'', Professor Maxon promises that von Horn can marry Virginia if he rescues her, in the heat of the moment. Afterward, he realizes that this was a problem since he had not gotten [[ChildMarriageVeto Virginia's consent]].

* In the backstory of ''Literature/PercyJacksonAndTheOlympians'', Luke promises Annabeth that the two of them and Thalia would be a family, and wouldn't fail each other like their birth families had.

Then, at the very end of the final book, he becomes TheAtoner: [[HeroicSacrifice he stabs himself]] to prevent Kronos's rise. "Promise."]]
* In Creator/GeorgeMacDonald's "[[http://www.online-literature.com/donne/3643/ Port In A Storm]]", the narrator got his uncle to not interfere with his wooing the uncle's wealthy niece, despite the appearance of trying to get at her money, by bringing him port to drink during a storm and collecting this as his reward.

* ''Series/{{Torchwood}}'': "Tommy, you're my big handsome hero, and I need you." (Interesting Western example with English and Japanese characters as the promiser/-ee.)
* In ''Series/{{Farscape}}'':
** John promises to give Scorpius all of the wormhole knowledge in exchange for help rescuing Aeryn. This debt is later wiped out when John comes up with a way of hurting the Scarrans, which makes Scorpius VERY happy.
** John promises to Aeryn that he wouldn't hurt Scorpius, since Scorpy saved her life. Aeryn releases him from the promise. They never intended to kill him, anyway.
* [[Series/LifeOnMars2006 Sam Tyler]] promised Annie he wouldn't leave her at the end of the finale, and mentioned that promise to his mum afterwards. [[spoiler: And he kept his promise.]]
* Several promises have been made on ''Series/{{Merlin}}''. Freya promises that one day she will repay Merlin for his help, and does so by delivering Excalibur into his keeping. Arthur promises Guinevere that when he is King, they'll be together.

* In TheCowardOfTheCounty by KennyRogers, Tommy promises his father, who is dying in prison, not to follow in his footsteps, and to avoid trouble whenever possible. Everyone called him the coward of the county due to his promise and his avoidance of conflict, but after his lover was raped, Tommy attacked her rapists and beat them soundly.

[[folder:Video Games]]
* [[{{Halo}} "After I'm through with]] [[BigBad Truth]]..." "Don't make a girl a promise... if you know you can't keep it..." This leads to a CrowningMomentOfHeartwarming in the third game:
---> Cortana: "You found me. But [[BreakTheCutie so much of me is wrong]]... [[MindRape out of place]]... you might be too late..."
---> [[TheHero Master Chief]]: "You know me. [[IGaveMyWord When I make a promise]]..."
---> Cortana: "...You... keep it. ...I ''do'' know how to pick 'em..."
---> Master Chief: "Lucky me."
* One of the story paths in ''VideoGame/BlazBlue'' had Bang Shishigami who was at first being seen as an annoying StalkerWithACrush by [[MsFanservice Litchi Faye-Ling]], until he jumped in and saved both her and Arakune from Hakumen. Bang opts to do a HeroicSacrifice while Litchi escapes; and asks to meet her in a bar when it's all over, and Litchi promised to do so. Unfortunately, it's a HeroicSacrifice [[YankTheDogsChain for real; Bang presumably dies and we don't know if Litchi even remembered him and]] ThePromise. The Kaka clan, however, made him a posthumous hero.
** ''Continuum Shift'', however, uses a variation. Litchi still made the promise and Bang actually survived. While they didn't exactly meet in a bar, it is clear that from that point on, Litchi grew to respect Bang tremendously and treats him with kindness and compassion.
** Litchi herself has a very dramatic version that influences her actions. She made a promise that she will save her colleague Lotte Carmine, who is now Arakune, no matter what happens to her. Unfortunately, fulfilling this promise is a hard thing to do since it involves corrupting herself to the Boundary to the point she's getting very near to become another Arakune, she had to take the offer of someone ObviouslyEvil like Hazama to join NOL and becoming a 'bad guy' in general and eventually [[spoiler:helping Relius Clover in his plan to exterminate all life and create a new world where Lotte can be prevented from becoming Arakune]], all of these fill her with a huge dose of remorse, but she feels obliged to follow through to the end, even if she could be happy enough by leaving him alone, and especially even if other people consider her stupid for trying to save someone they think is 'beyond saving' and wouldn't bother.
** Perhaps hilariously, even [[spoiler:Relius Clover]] joins in the act in ''Chronophantasma''. [[spoiler:He goaded his son Carl to his side by first having Litchi on his clutches 'on her own will' (see above) and the promise that he will restore Ada, Carl's biggest goal in life for the moment. Considering Relius didn't break a sweat in putting him down, when Carl actually did on his own will, we all know that Relius would make it an EmptyPromise. But... then he saw Bang Shishigami thwart his magnum opus of a plot despite having both Litchi and Carl, who Bang liked very much, as his pawns, and then he's dumped by the Imperator (revealed by Izanami) to 'die' and with him being ThePerfectionist, Relius fell into a VillainousBSOD and is railroaded to commit himself to Carl's previous promise to restore Ada before he could die, which he accepts because he got nothing else to look forward into.]]
* In PlanescapeTorment, your character can actually do this as a dialogue option. Sometimes, dialogue choices (in some specific, important and dramatic scenes) will have a declaration of intent hidden, such as "Truth", "Lie", and, most importantly, "Make Vow". Those dialogue choices affect your CharacterAlignment: you become more Lawful if you tell the truth, and more Chaotic if you lie.
* A promise is the driving force behind the plot of ''VideoGame/{{Disgaea 4|A Promise Unforgotten}}'', hence the title. The main character, Valvatorez made a promise to give his Prinny trainees a sardine once they finish their training. However, the Netherworld's government decides that all of the Prinnies need to be exterminated to cut back on expenses, which would keep him from fulfilling his promise. So naturally, he decides to overthrow the government.
* ''KingdomHearts'': At the end of the first game Sora makes a promise with Kairi that he'll return to her and the island with Riku someday.
** In a deliberate echo in ''VideoGame/KingdomHeartsII'', Roxas makes a promise that he'll meet up again with his friends in Twilight Town. [[spoiler:Sora fulfills it vicariously for him, and gets the Oathkeeper keyblade for doing so.]]
* ''FinalFantasyVIII'' has the iconic promise between Squall and Rinoa.
--> '''Squall:''' "How about this... I'll be here..."
--> '''Rinoa:''' "...Why?"
--> '''Squall:''' "The reason why you couldn't find me was because we haven't promised yet."
--> '''Rinoa:''' "Promised...?"
--> '''Squall:''' "I'll be waiting for you. If you come here, you'll find me. I promise."
--> '''Rinoa:''' "I'll be here, too. It's a promise! Thanks Squall! Next time, we'll meet for sure!"
** In the ending FMV when Squall is lost in Time Compression, Rinoa manages to find him and bring him back to the location of the promise.
* Cloud's childhood promise to Tifa that he would protect her if she ever got into trouble from ''FinalFantasyVII''.
** He has a tendency to show up a little late.
* ''VideoGame/DragonQuestVIII'': Trodain promised Argonia that their kingdoms would be united by an ArrangedMarriage. Unfortunately, Argonia's Prince is [[PrinceCharmless Prince Charmles]], which causes King Trode no small amount of grief after meeting him and seeing what an utter boor he'd promised his daughter's hand to. In [[MultipleEndings both endings]], he decides [[spoiler: [[ScrewTheRulesImDoingWhatsRight Screw The Promise, I'm Doing What's Best For Medea]] and fights to stop the ceremony]] -- the GoldenEnding also lets him [[spoiler: TakeAThirdOption and let her marry Charmles' just-discovered cousin]]. Plus, [[spoiler:it's implied that 'The Hero' had the right of succession anyway.]]
* In [[CastlevaniaSorrow Castlevania: Aria of Sorrow]], Soma Cruz asks [[spoiler:Julius Belmont]] to promise to kill him if he turns evil. Thankfully, the person making the promise is reliable and more than strong enough to fulfil said promise if it comes to that. [[spoiler:In Aria's bad ending, Julius turns up in the throne room to kill Soma, and in Julius Mode in ''Dawn'', Julius gets Yoko and Alucard's help to take down Soma.]]
--> '''Soma:''' ... I've got a favour to ask of you.
--> '''[[spoiler:Julius:]]''' What is it?
--> '''Soma:''' From here. I will set off to fight against my own fate. If I lose the battle... And I become reincarnation of evil, I want you to kill me.
--> '''[[spoiler:Julius:]]''' ... I will... I promise.
--> '''Soma:''' Thanks. Now I can go into this battle without reservations.
--> '''[[spoiler:Julius:]]''' Farewell, my friend. Don't let me use that whip again.
* In ''{{Persona 3}} [[UpdatedRerelease Portable]]'', a romantic vow to stay together is apart of the [[LevelUpAtIntimacy5 last rank of the Justice Social Link]] for the female protagonist. What makes it so important is that it's with Ken Amada who's very insecure about their [[MayDecemberRomance relationship]].
** A bigger promise is for [[TrueCompanions SEES]] to meet up again on Graduation Day, [[spoiler:if they manage to beat Nyx]].
* In ''{{Solatorobo}}'', Elh promises Red a billion rings if he helps to complete the Rite of Forfeit. [[spoiler:Of course, Elh actually doesn't ''have'' a billion rings and, if the Rite had gone [[HumanSacrifice as it usually did]], Red wouldn't have needed them anyway. Red survived, however, and instead of being angry, he just [[CrowningMomentOfHeartwarming invited Elh to join his team]] - [[IWasJustPassingThrough ostensibly to work off that debt]], of course, but [[AwLookTheyReallyDoLoveEachOther nobody was fooled]].]]
* In ''VisualNovel/HatofulBoyfriend'', the entire Bad Boys Love route and storyline hinges on the fulfillment of a promise from long ago. Given [[DatingSim the premise of the game]], you might think that it's going to be along the lines of a ChildhoodMarriagePromise, but it...really, ''really'' isn't.
* If Shepard enters into a romantic relationship with Liara in ''Franchise/MassEffect'', at the conclusion of ''Lair of the Shadow Broker'' in ''VideoGame/MassEffect2'', Liara asks Shepard to promise her that s/he's always coming back. S/he does. Both she and Tali beg you to come back after the final battle in VideoGame/MassEffect3. Since it's currently assumed that [=ME3=] is the end of the series (for Shepard), in one out of three endings, with a high enough EMS score, you can assume he keeps his promise. Who knows what'll happen now that Bioware has broadly hinted that Mass Effect 4 might be worth keeping your saves for though.

** He's incensed when his son, Roy, gets to go on to the afterlife proper, since Roy didn't fulfill the terms of the Oath either. It's pointed out by a Being of Pure Law and Good that Roy gets to move on because he died in direct pursuit of the quest his worthless flake of a father dumped on him by consciously abandoning it.
