History Manga / SleepyPrincessInTheDemonCastle

* BoxAndStickTrap: The Demon King uses one to recapture the Princess after an escape attempt (because she wanted to go shopping in the human realm). There was a futon inside the trap, and it closed when she fluffed the pillow. The anime's 10th episode replaces it with a steel cage.

* RunningGag: The anime has a 2 shot scene of the Princess knocking her brush against her bars, followed by the Teddy Demons floating over with the keys to her cell, over multiple quests and episodes to play up what a CardboardPrison her cell actually is.

* AllLoveIsUnrequited: As the story goes on, there are an increasing number of characters that pine for others that are completely oblivious to their affection, while also being oblivious to the affection of people pining for them. The Princess herself has the attention of Hero Dawner, Demon King Twilight, [[spoiler:Demon Cleric Leonard]], and Stray Kamaitachi. Meanwhile, Twilight is pined for by Dragon Lady Zetsuran, while Zetsuran is pined for by Sand Dragon.

* AdaptationDeviation: The reason and way the Princess gets her Tire Demon armor is different in the manga and the anime. The anime has her needing something to cover herself in to endure the coldness of the Ice Area, with her seeing the Tire Demon and then attacking him with her giant pair of scissors. The manga, meanwhile, has the Princess already having the armor at this point, as she originally needed it to allow the Thunder Dragon to apply some electric shock to her stiff shoulders without killing her (especially considering how the original attempt resulted in her getting punished in the form of the Demon Cleric keeping her dead for a week the next time she dies), with her gaining it via an army of Teddy Demons attacking the Tire Demon.

* ShoutOut:
** The Princess' name is Aurora just like the titular character in Disney's ''WesternAnimation/SleepingBeauty''.
** The princess occasionally uses the battle HUD from ''Franchise/{{Pokemon}}''.
** The people on the recurring infomercial resemble [[VideoGame/DragonQuestV Bianca and Nera]].
** The princess imagines seeing the main characters of ''Anime/MyNeighborTotoro'' jumping on her bed in chapter 5.
** In chapter 11/episode 3, after the princess asks him to touch her (as in the pressure points in the back that would make her fall asleep) in her room, the Demon Cleric, mistaking the request for [[PedophilePriest something else]], makes the ''Manga/AshitaNoJoe'' final page pose.
** Chapter 17/episode 4 has a one-and-a half page/minute long ''Manga/DetectiveConan'' recreation, with the princess showing up in a Demon King's Castle newspaper a la Shinichi Kudo and an explanation of how she wound up with the body of a child, as a just barely different version of Conan's {{Leitmotif}} plays in the background in the anime version.
** In chapter 19, the ghost shrouds [[Anime/AttackOnTitan receive a grim reminder...of why they live in constant fear of the princess]], complete with a giant princess peeking over the battlements.
** The Neo Gearbolter portion of chapter 24/episode 6 is one big nod to ''Franchise/NeonGenesisEvangelion'', with its creator, Professor Gearbolt, resembling Gendou Ikari (and even doing a number of his poses), the place where Neo Gearbolter was being kept looking a lot like the docking area of EVA-01, and the Magnespear eventually being used like the Spear of Longinus.
** One of the classes that the princess dresses up as in volume 3 is [[Franchise/SuperMarioBros a plumber which improves her jumping ability]]. Also, the aerial vehicle Cer, Ber, & Rus were given to use that the Princess swipes in episode 7 has a bit of a resemblance to the [[VideoGame/SuperMarioWorld Koopa Clown Car.]]
** The Demon Cleric visualises the princess and the cat demon doing the classic ''Anime/DragonBallZ'' FusionDance move to merge in chapter 31.
** In chapter 67/episode 10, as the Princess and the demons accompanying her (the Demon King, Demon Cleric and Great Red Syberian) are about to enter the human town, they make a pose (complete with sound effect kanji) similar to the one made by the protagonists of ''[[Manga/JoJosBizarreAdventureStardustCrusaders JoJo's Bizarre Adventure: Stardust Crusaders]]'' as they embark on their quest to kill DIO.
** When the princess' dream is shown in chapter 77, it resembles [[Franchise/SuperMarioBros the Mushroom Kingdom]] complete with floating blocks and tall rounded mountains.
** The Princess in a stack of swim rings in chapter 102 reminds the demons of the Pop-Up Pirate game.
** Chapter 103 takes its title from ''Anime/{{Arrietty}}'', the scanlation going with its Disney name and calling it ''The Secret World of Suyarrietty'', and the official translation going with the direct translation of its Japanese name and calling it ''The Borrower Suyarrietty''.
** The masks the Princess makes for the cafe during the festival arc are copies of [[Franchise/FridayThe13th Jason Voorhees's hockey mask]].
** One of the classes the Princess dresses up as in volume 10 is a Franchise/{{Ghost Buster|s}}.
** Chapter 149, which's about the Princess becoming an idol, is called ''[[Franchise/TheIdolmaster THE pRINCESS M@STER]]''.
** The entirety of Chapter 171 is an extended reference to ''Manga/HowHeavyAreTheDumbbellsYouLift'', down to the title being almost the same, just swapping "dumbbells" with "slimes".
** Chapter 199 is one big parody of the ''VideoGame/AnimalCrossing'' franchise, with all the members of the Demon King's Castle getting addicted to a game called "Leave Forest".

* AlwaysChaoticEvil: While the Demons of now are friendly, it has been repeatedly mentioned that before, they were more or less genuinely evil and wars were caused between them and the humans. This naturally caused a divided line between the two races. Those like Twilight and [[spoiler:even his father at one point]] try to bridge the two races from the past.

** In chapter 67/episode 10, as the Princess and the demons accompanying her (the Demon King, Demon Cleric and Great Red Syberian) are about to enter the human town, they make a pose (complete with sound effect kanji) similar to the one made by the protagonists of ''[[Manga/JoJosBizarreAdventureStardustCrusaders JoJo's Bizarre Adventure: Stardust Crusaders'' as they embark on their quest to kill DIO.

* SanDimasTime: During the TimeTravel arc, each time they jump time passes at the same rate in both the past and the present. However, in this case it's {{justified|Trope}}, because Alazif, the one time-traveling, is only doing so because of PowerIncontinence, so each time he transports the Princess, Cursed Musician, and himself, he jumps 10 years on the dot, meaning after a day passes in the present of the AlternateTimeline, so too does a day pass in the past, which coincidentally puts them a few minutes before the Demon King's coronation, the point where the timelines diverge, giving them a limited amount of time to fix things.

* ButterflyOfDoom: The entire reason why the darker, more serious AlternateTimeline came to be was because the Princess stole the younger Demon King's futon. The reason is because it was the day of his coronation, and the futon was a supportive comfort gift by the Demon Cleric. With the futon stolen, the Demon King took this as a sign that he needed to be more independent, and thus fired all the weaker demons and enforced stricter rules for the Demon Army.

* ForWantOfANail: Chapter 200 has Alazif coming down with Grimoire Rhinitis, which causes him to TimeTravel with Princess and Cursed Musician whenever he sneezes. After the second sneeze, he brings them to an AlternateTimeline where Cursed Musician replaced Demon Cleric as one of the Ten Elders, which results in everybody becoming much darker and more serious about being evil demons due to lacking Demon Cleric's GoodShepherd influence.

* AdaptationalEarlyAppearance: Episode 5 of the anime includes content from Chapter 37 of the manga, introducing Neo Alraune and Poseidon to the story a lot earlier.

* CouldHaveAvoidedThisPlot: The plot of chapter 90 involves the princess and Poseidon doing their best to avoid getting flu shots due to their shared fear of needles. At the end, after they're finally caught and given the shots, it's pointed out if they had Hi-Potions, the shots wouldn't have been necessary. Except the Princess drank so many of them that year they didn't have enough and had to resort to the injections, with the realization that their problem was all her fault causing the Princess to ''[[OOCIsSeriousBusiness earnestly apologize]]'' to Poseidon for the incident.

* SchizoTech: For the most part, the world seems to be a medieval fantasy world. However, things like mecha and nanomachines are apparently pretty common-place.

Also, the arial vehicle Cer, Ber, & Rus were given to use that the Princess swipes in episode 7 has a bit of a resemblance to the [[VideoGame/SuperMarioWorld Koopa Clown Car.]]

** The members of the Goodereste family have names relating to sleeping. While the given names for the three revealed so far are the same (Aurora for the Princess, her mother, and her aunt), their middle names are most notable. The Princess is S(u)ya Lis, the equivalent of the "ZZZ" onomotopoeia, referencing her frequent attempts to sleep, her mother is Nem(u), which literally translates to "sleep", and her aunt is Coma Lis, referencing how she frequently enters a coma-like sleep that requires great effort to wake her up.

* {{Baku}}: In the castle's basement is a Bakumu and an army of Nightbears. Nightbears are a teddy bear-like monster that eats the nightmares of the castle's residents and converts it into nightmare fog which feeds the tapir-like bakumu. In Chapter 22, the nightbears are too busy collecting nightmares about the Princess -- her antics around the castle causing bad dreams for the monsters that live there -- to do their jobs properly, thus causing indigestion for the Bakumu and bad dreams for everyone else. It is not until the Princess grooms the nightbears do things return to normal.

** Chapter 199 is one big parody of the ''VideoGame/AnimalCrossing'' franchise, with all the members of the demon castle getting addicted to a game called "Leave Forest".

* CoincidentalAccidentalDisguise: The Princess's Tire Demon armor gets covered in frost while exploring the Ice Region in search of some way to cool her cell. The inhabitants mistake her for their area boss Ice Golem, which she exploits to get an igloo constructed in her cell. She also takes advantage of the resemblance on subsequent visits.
