The Promise

""Lootie, I promised him a kiss." "Your Royal Highness," said Lootie, suddenly grown very respectful, "must come in directly." ''"Nurse, a princess must not break her word," said Irene, drawing herself up and standing stock-still. . . . "Never mind, Princess Irene," he said. "You mustn't kiss me tonight. But you shan't break your word. I will come another time. You may be sure I will.""

- George MacDonald, The Princess and the Goblin

A dramatically-made promise that operates like a verbal Chekhov's Gun. The Promise will eventually be called in—sometimes at the climax and sometimes as the catalyst for a whole arc or series—and the promiser will be required to act.

Whether they succeed, fail or refuse to keep their promise depends almost entirely on the idealism-level of the show. Though other factors, such as whether they were told what they had to do, or if it was a Leonine Contract, may come into play.

Anime and Manga

 * This is basically the trope that sets in motion Mashiro's persistence to become a mangaka in 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 The Promise in her vow to save Anthy in Revolutionary Girl Utena.
 * In the Soul Society arc of Bleach, Ichigo will save Rukia... whether she likes it or not.
 * Later on, during the Arrancar Arc, Ichigo vows to
 * Keitaro holds strongly to his 15-year-old promise to get into Tokyo University for/with a nearly-forgotten girl in Love Hina. 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 Robot Girl Moe.
 * Both Lottie and Sara in Soukou no Strain promised to become Reasoners and see their brothers again.
 * In Ranma ½, 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.
 * 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.
 * Another plot relevant promise is Sasuke promising to avenge his family by killing his brother.
 * Well, yeah. He does. He's devoted his life to turning himself into a vengeance machine. If the original quest had come to a satisfying conclusion, maybe he could have moved on and rebuilt himself into something new, but instead Itachi acted very weird and then Madara came in and filled in the plotholes with the fact that he threw away everything for nothing because the person he hated more than anything had loved him more than anything, and his true enemies were the people who'd forced them into that position. Naturally all he can do is kill someone.
 * 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 Yu-Gi-Oh!, Jounouchi's/Joey's major motivation is his promise to duel with Yugi and get back his Red-Eyes Black Dragon card.
 * Elfen Lied 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
 * A second example is
 * In Digimon Adventure 02, 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, More Than Mind Control, and some heavy psychological trauma later, however, and he's the Digimon Kaiser.
 * In the previous season, Takeru promises to Sora that he'd protect Hikari. A promise which he still takes rather seriously in Digimon Adventure 02, 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 Tokyo Babylon.
 * Super Robot Wars 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 to actually rescue her and restore her mind.
 * And also included in 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 wishs 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."
 * Katekyo Hitman Reborn: Squalo promised 8 years ago to Xanxus that he will never cut his hair until Xanxus becomes the boss of Vongola. And he did, . Obviously because.

 * Madlax has Madlax and Vanessa promising each other to survive.
 * The Place Promised in Our Early Days has such a promise as the entire backbone of it's plot.
 * Yu-Gi-Oh! GX: 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 hir motivation when sie returned in season three. Then one remembers that Yubel can freely alter people's memories, and has no moral compunctions that would prevent hir from using these powers to get hir 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.
 * 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.
 * Chrono Crusade has several promises that the main characters take very seriously. The first is that made Chrono promise to "live", which is implied to be the only reason he . Also, the manga version shows Joshua and Rosette promise as children to . Also, when Rosette made 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 really pissed.
 * In The Secret Agreement, Iori tells Yuuichi that he loves him more than anything and 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 offer his life for him to take.
 * In Tiger and Bunny, Kotetsu made a promise to his wife on her deathbed to continue to be a Hero after she was gone.

 * Sosuke's mother promises she will come back; Sosuke and Ponyo set out in search of her when she doesn't.
 * Code Geass has several. A couple of them are found on the Pinky Swear page and are explained in more detail there. A non-pinky promise comes during arguably the biggest Crowning Moment of Heartwarming in the series; when Lelouch realises how much his friends care about him, he tearfully promises them that he'll set off fireworks with them again someday.
 * In Gate 7, Hana is waiting for someone who has not been revelead yet and once they are reunited, zhe will keep hir promise.

 * In "Bearskin", the hero, appalling shaggy, filthy and ragged, but rich, rescues a man from financial distress, the man promises that he may marry one of his daughters. Only the youngest is willing. However, his appearance stemmed from a Deal with the Devil, and that being over, he cleans up nicely and formally arrives at their house as a wooer—or, in some variants, at his own wedding. The older sisters are impressed, but the youngest, being the sort who would marry a hideous man to redeem her father's promise, ignores him until he proves that handsome as he is, he is still the same man whom she promised to marry.
 * In "The Frog King", the king insists the princess must keep her promise to the frog who helped her.

 * In The Lord of the Rings, Aragorn can summon the Dead to fullfill the oath of assistance that they did not respect centuries before.
 * Don Vito Corleone basically operates by getting these from a great number of people. (The novel says that 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  gets whacked.)
 * In Robert E. Howard's "The Vale of Lost Women" Livia promises herself to Conan the Barbarian if he will free her from her captor. Then she bolts in panic.

And many more!

 * In Between the Rivers by Harry Turtledove, the protagonist in a grandstanding moment vows that he won't marry his sweetheart until the completion of the trading expedition he's about to embark on. 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 Warrior Cats 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.

 * Torchwood: "Tommy, you're my big handsome hero, and I need you." (Interesting Western example with English and Japanese characters as the promiser/-ee.)
 * Averted in Farscape with John and Scorpius. John promises to give Scorpius all of the wormhole knowledge in exchange for help rescuing Aeryn, but this debt is later wiped out when John comes up with a way of hurting the Scarrans, which makes Scorpius VERY happy. Played for Laughs with John's promise to Aeryn that he wouldn't hurt Scorpius since Scorpy saved her life. Aeryn releases him from the promise, but they never intended to kill him, anyway.

Bang opts to do a Heroic Sacrifice 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 Heroic Sacrifice for real; Bang presumably dies and we don't know if Litchi even remembered him and The Promise. The Kaka clan, however, made him a posthumous hero.
 * In Planescape: Torment, 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".
