!!This series provides examples of:

* AgeLift: Comet is 12 in the anime series while she was in an adult age in the manga and live action series
* AnnoyingYoungerSibling: [[spoiler:Averted for Tsuyoshi and Nene.]]
* CheerfulChild: Everyone under age 15. [[spoiler:Subverted with Meteor, who is too [[JerkAss jerkish]], and Shun, who is too [[WiseBeyondTheirYears mature.]]]]
* CleaningUpRomanticLooseEnds: [[spoiler:Meteor and Shun.]]
* CuteWitch: Comet is this type of MagicalGirl.
* DarkMagicalGirl: Meteor
* [[spoiler:DefrostingIceQueen/ TookALevelInKindness: Meteor grows less obnoxious and more caring to others as the series progresses.]]
* EasyAmnesia: [[spoiler: Keisuke]]
* EverythingsBetterWithPrincesses: Played straight with Comet [[spoiler: and eventually double-subverted with Meteor]].
* FairyCompanion: Rababou (a dog-like creature) and Mook (a bird-like creature). [[spoiler: And Rabapyon (Aunt Spica's fairy companion, who is rabbit-like creature).]]
* FishOutOfWater: Comet gets hit with this hard when she first arrives on Earth. By the end of her first day, she's reduced to tears because she can't figure out how to get food, since she has no Earth money.
* HalfIdenticalTwins: Nene and Tsuyoshi.
* HarmlessVillain: Meteor, [[SlidingScaleOfAntiVillains with the dash of type 1 anti-villain]], thanks to her pride. [[spoiler:In fact, [[CutLexLuthorACheck she's more effective in doing good than doing evil things.]]]]
* IdolSinger/ TeenIdol: Shun Imagawa, a RareMaleExample. [[spoiler:Also a rare example where the idol looks more like [[OlderAndWiser late]] Music/PaulMcCartney than Music/JustinBieber.]]
* {{Jerkass}}: Meteor
** [[spoiler:HiddenHeartOfGold: That doesn't mean she's totally heartless, though. Sometimes she even willingly helps Comet with problems she can't handle on her own. It helps that in such cases, Comet doesn't hesitate to ask nicely. In some cases, she even helps Comet ''before'' Comet asks for help, especially if the problem irks her pride.]]
* LoveHurts: [[spoiler:When the Prince is found and she had to return to her world, Meteor decides to [[LaserGuidedAmnesia wipe out Shun's memories about her]]. Comet [[WhatTheHellHero calls her on this]], which is pretty surprising because Comet [[NiceGirl is such a sweet girl]] who ''rarely'' loses her temper and also because Meteor [[CharacterDevelopment had grown into likeable character at this point]]. [[IDidWhatIHadToDo Meteor's]] [[ShutUpKirk response]] [[TearJerker is one of the most poignant scenes in this series]]. PlayedForLaughs in the last scenes of the series, where Meteor comically regrets her decision to mindwipe Shun.]]
* MagicalGirlQueenlinessTest: Basis for this series
* MagicWand: They don't call her "baton girl" for nothing.
* MuggleFosterParents: Comet is taken in by a kindly {{Muggle}} family during her stay on Earth. On the other hand, Meteor barges into an old couple's house and [[MindControl casts a spell on them to make them think]] they've always known her.
* NiceGirl: Comet, in spades. She wouldn't look out of place as [[Manga/CardcaptorSakura Sakura's]] friend.
* NiceGuy: [[spoiler:Shun Imagawa, UpToEleven.]]
* [[NiceJobFixingItVillain Nice Job Fixing It, Anti-Villain]]: Meteor should really listen to Mook more...
* PantyShot: There is a brief one in episode 4 while Comet is climbing onto a boat.
* PrincessesPreferPink: Well, heroic princesses do.
* PunchClockVillain/ OnlySaneMan/ [[spoiler:HypercompetentSidekick]]: Mook, true to her name, is not terribly thrilled to be Meteor's partner and spends a lot of time trying to dissuade Meteor from carrying out her nastier ideas. [[spoiler:Since most of her "nastier" ideas tends to put her on the ''huge'' risk of making fool of herself... Yeah.]]
** Rababou tends to act as OnlySaneMan, nagging Comet to do her job to find the Prince while all Comet wants is to explore the world.
* RebelliousPrincess: Comet is a very mild-mannered example. When we first meet her, she's at a betrothal party complaining about her uncomfortable ball gown and wishing she could just ditch the party to go star-gazing, and when she's sent to Earth to find the prince, she's far more interested in exploring this strange new world than she is in chasing after some guy she's never met.
** An interesting case with Meteor. [[spoiler:After Comet denounces her betrothal with the Prince of Tambourine Star near the end of the series, Meteor does the same, announcing that she has no intention of marrying a wishy-washy Prince and that she would rather find her own way to become queen. Hearing this, her mother, who is the one who pushed her to pursue a relationship with the Prince, is actually ''pleased'' with this answer, since this means that Meteor had developed a backbone befitting for a queen.]]
* RedEyesTakeWarning: Meteor
* TheRival: Meteor
* RoseHairedSweetie: Comet
** Basically this was an AdaptationDyeJob for this anime, the original manga has her blonde while in live-action adaptions have her black (although the colorized anime sequence of the 1960s live-action version made her redhead)
* RoyalBrat: Meteor is as obnoxious as Comet is sweet. [[spoiler: And then CharacterDevelopment sets in.]]
* RunawayFiance: Comet considers running away from the party where the prince will be betrothed either to her or Meteor, only to find that the prince beat her to it by running away himself.
* {{Sleepyhead}}: Shun Imagawa. Justified; Being a TeenIdol is very demanding job, and he took it ''very'' seriously; [[spoiler:Even ''his own manager'' thinks that ''he is too sweet'' to his fans.]]
* ThemeNaming: The other worlds all have musical names: Tambourine, Harmonica, Castanet, etc.
* TransformationSequence
* TransformationTrinket: Comet's pendant. It also serves as a {{hammerspace}} for Rababou to hide in.
* VerbalTic: Rababou says "-bou" after all his sentences.
* [[WellDoneSonGuy "Well Done, Daughter" Girl]]: A mild case with Meteor. [[spoiler:[[StealthMentor In reality, her mother actually wanted her to develop her own strong personality and ability to decide for herself, so she could be a strong queen.]]]]
* WiseBeyondTheirYears: A mild case with Comet. A stronger example with [[spoiler:Shun Imagawa.]]
