[[caption-width-right:300:''"All these people are doing their best to find true love! I will not let you laugh at it!"'']]
Lucia is the [[MagicalGirl typical shoujo heroine]]: ditzy and lovestruck, but with a pure heart and a sense of love for her friends.
In the manga, she was raised to believe that she was a normal mermaid civilian, and lived on the surface as a human with her guardians, "sister" Nikora and "pet" Hippo (who is a penguin).
In the anime, she's always known that she is the Princess of the North Pacific Ocean, Pink Pearl Voice. Great, right... except for the "pink pearl" bit.
The pearl that gives her her power and is directly tied to her life force is gone; she gave it to a little boy to save his life when they were six. She gets it back from the boy, who turns out to be her classmate and crush Kaito, and realizes that she has to find the other ocean princesses and save the world. She's also expressly forbidden to confess her love or true identity to Kaito, but she's certain that she won't turn to foam if she finds some loophole. Little does she know that nobody turns to foam when they confess anyway...

* ChangelingFantasy: Manga only.
* CovertPervert: Not as much as Hanon, though.
* CuteClumsyGirl: Lucia trips over things all the time.
* [[DangerousSixteenthBirthday Dangerous Thirteenth Birthday]]: Of course, Lucia's always known she's a mermaid, but in the manga she didn't find out she was a Mermaid ''Princess'' until her 13th birthday.
%%* TheDitz
* FearOfThunder: Possessed this trait.
%%* FirstKiss
* GenkiGirl: Easily the most energetic and positive character in the series.
* GirlishPigtails: Lucia has ditz/magical girl pigtails.
* GRatedDrug: She gets drunk off cola in the manga.
* HairDecorations: Wears two red ribbons while in human form.
* HairIntakes: Her hairstyle has two intakes that kinda look like cat ears.
* HairOfGoldHeartOfGold: She's blonde in mermaid form, in the anime, and in many manga pictures (it's very inconsistent), and she's a cute, kind and innocent princess.
* HeartSymbol: Cheesy hearts appear when Lucia performs her "Love Shower Pitch".
%%* TheHero
* HeroesWantRedheads: The manga's inconsistent colouring means that sometimes her boyfriend is the redhead, and sometimes ''she'' is.
* IdiotHair: She has a cowlick that stands prominently atop her head. This is reflective of her ditzy personality.
* ImageSong: "Koi wa Nandarou" ("What is Love?") and "Splash Dream." In the second season, "Mother Symphony" may also count.
* InterspeciesRomance: a pink Mermaid Princess who loves Kaito since her childhood.
* IWantSong: "Koi wa Nandarou" and "Splash Dream".
* KissingUnderTheInfluence: Literally in the manga, {{Bowdlerise}}d in the anime to be the result of a magic jewel.

* LoveTriangle: Lucia-Kaito-Michal.
* MeaningfulName: Lucia is Latin for 'light', and Nanami is Japanese for 'seven seas'.

* NonstandardCharacterDesign: Weird case with her being the main character and it's quite subtle. While the other mermaids have CurtainsMatchTheWindow which match their tail does she have HairOfGoldHeartOfGold with InnocentBlueEyes.
* NoPronunciationGuide: Her name Lucia is actually pronounced "Luchia", which leads to translations having that spelling of her name.
%%* ThePowerOfLove
* PinkHeroine: Her tail as a mermaid is pink, and her idol form outfit consists of a pink dress, pink gloves, and pink boots.
* PrincessesPreferPink: Her tail and shell-bikini as a mermaid are pink, and her idol outfits are entirely pink as well.
%%* ProphecyTwist
%%* PuppyDogEyes
* RagsToRoyalty: She's a Sleeping Beauty in the manga and a Snow White in the anime.
* RescueRomance: Lucia saved Kaito when they were children and they've remembered each other ever since. [[spoiler:In the manga's final bonus chapter, it turns out that he also saved her at the same time when she was struggling to keep him afloat.]]
* SayItWithHearts: Not as often as Hanon, but a lot, including her "Love Shower Pitch."
* SayMyName: '''KAITOOOOOOOOOOOOOOOO!'''

[[caption-width-right:250:''"I know how to attract the guys, and I'll ♥ teach ♥ you! ♥"'']]
Hanon is a flirty, carefree, all-around girly-girl that befriends Lucia on her first day of school. She's more serious than she looks, however, and has been watching Lucia for days and confronts her with her true identity at the end of the first chapter. Hanon is actually the Princess of the South Atlantic Ocean, otherwise known as Aquamarine Pearl Voice. With her strength and happy nature, she makes a great first ally for Lucia, even though they're always at each other's throats -- in particular, Hanon doesn't approve of Lucia dating Kaito at first, even though she's all over a human man, who, at that, happens to be her own ''teacher''. Again, though, despite her peppy, fluffy, hypocritical image, Hanon feels tremendous guilt for the fate of her kingdom, which was besieged with her as the only apparent survivor.

!!Tropes associated with Hanon:
* AsYouKnow: Hanon and Nicola like to go on about the rules of the mermaid world. Lucia usually actually doesn't know this. She's just that dense (or overprotected).
* TheChick: "Flirty, carefree, all-around girly-girl"
* CovertPervert: Hanon is a hormonal teenager, all right.
* DeclarationOfProtection: What "Ever Blue" is about; protecting the ocean, your loved ones, etc.
* DoomedHometown: Like most of the others, she fled a ruined homeland.
* FirstKiss: Something she's dreamt about for ages.
* FirstNameBasis: Hanon thrusts it upon everyone she meets.
* HotForTeacher: Her first crush being Tarou Mitsuki.
* ImageSong: "Ever Blue" and "Mizuiro no Senritsu" ("The Aquamarine Melody").
* IWantMyBelovedToBeHappy: Eventually decides this despite how much it hurts her for Tarou to be in love with someone else.
* TheLancer: She likes disagreeing with Lucia.
* QuirkyHousehold: Once Hanon moves in, the Shinju-yu/Pearl Piari becomes this instantly.
* SatelliteLoveInterest: She tends to go for guys who she just thinks are cute. Tarou is one of these; as crushed as she is to learn that he's [[RealityEnsues interested in people his own age]], she eventually gets over it when he leaves.
* SayItWithHearts: Every other sentence.
* ThereIsAnother: A lot of Hanon's subjects did survive.
* TomboyAndGirlyGirl: She's the girly one to Rina.
* TownGirls: The Femme to Lucia's Neither and Rina's Butch.
* {{Tsundere}}: Towards Nagisa. Since he's not her usual type, she tries her best to ignore that he's there.
%%* UmbrellaOfTogetherness
* YouGottaHaveBlueHair: Most people in the show, actually, but Hanon deserves a mention for literal blue hair.
!Touin Rina
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/rina_31.png]]
[[caption-width-right:350:''"It doesn't matter. Your true nature will come out soon enough."'']]
The standoffish transfer student that Lucia decides to befriend on a whim, Rina is idolized by her classmates as "cool" because she spends most of her time brooding and making the occasional sarcastic remark. She, too, is a princess: Green Pearl Voice from the North Atlantic Ocean. Rina acts as an emotional pillar for her friends, but she herself has issues that need to be dealt with. Even more so than Hanon, she carries a measure of guilt about her escape; after being forced to leave their countries behind, Rina and her friend, Princess Noel from the Arctic Ocean, were ambushed by Gackto and only Rina got away. Despite what she thinks of herself for this, she's a strong and loyal friend of her team.

!!Tropes associated with Rina:
* AllLoveIsUnrequited: Her crush on Kaito in the anime.
* AloofAlly: Didn't last long.
* {{Bifauxnen}}: [[Main/TakeOurWordForIt You couldn't tell by looking at her, but apparently, she is]]. She wears the boys' uniform, and Lucia and Hanon's first reaction to seeing her in the anime is "That was a girl... ''right''?".
* BokeAndTsukkomiRoutine: Rina wants to be a comedian in the anime. In one episode and its preview, she manages a decent routine with Lanhua.
* TheComicallySerious: Particularly in the anime, where she's still serious but has things added to her character like being obsessed with plasma [=TVs=] and wanting to be a comedian.
* CustomUniform: Rina wears the boys' uniform for no apparent reason.
* DontSaySuchStupidThings: On both the giving and receiving ends.
* DoomedHometown: She fled her home like many of the others when Gackt came along.
* FunTShirt: Her "It's cool" shirt with the penguin on it.
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]: Denies having anything going on with Hamasaki for ages.
* HeroWithBadPublicity: Gets this from Caren and the rest of the Antarctic Ocean during the first season. While Noel in fact [[HeroicSacrifice sacrificed herself]] to give her a chance to escape from Gaito, Caren's kingdom believes that Rina [[DirtyCoward abandoned Noel to save her own hide]].
* HimeCut: Fits with her status as a miko.
* ImageSong: "Star Jewel" and "Piece of Love."
* LayingOnAHillside: Rina does this a lot in the anime, especially in ''Pure'', when they had to reuse animation all the time and thus shots and whole chunks of scenes were repeated.
* {{Miko}}: In the manga, she works for a shrine to a spirit both mermaids and humans venerate.
* MysteriousWatcher: For one episode, before she turns out to be a Mermaid Princess herself.
* NewTransferStudent: Apparently has a lot of rumours about her when she shows up, though we don't actually hear any.
* [[NonActionGuy Non Action Song]]: "Piece Of Love" from ''Pure''.
* {{Otaku}}: In the anime, she's given such an obsession with plasma [=TVs=].
* RapunzelHair: In both forms.
* TomboyAndGirlyGirl: She's the tomboy.
* TownGirls: The Butch to Lucia's Neither and Hanon's Femme.
* {{Tsundere}}: Type B for Masahiro.

!Caren
[[quoteright:225:https://static.tvtropes.org/pmwiki/pub/images/images_2615.jpg]]
[[caption-width-right:225:''"Who said I'm joining you?"'']]
Brash, bitter and initially unkind, Caren, otherwise known as Purple Pearl Voice and the Princess of the Antarctic Ocean, shows up mid-way through the first arc to rescue Lucia and company a few times. That doesn't, as she makes clear, mean that she plans to join them or become their friend. Caren is the fraternal twin sister of Noel, and as such, has a deep personal grudge against Rina for escaping when the other princess did not. She takes it upon herself to rescue her sister ''alone'', and only when her brazen attempt gets her captured and the heroes rescue her but Noel sacrifices herself again does Caren realize that Rina wasn't selfish at all. She never quite integrates herself into the team for good, leaving more than once after the job's done, but is important enough to be listed with the main cast for the second half of the first arc/season.

->'''Age:''' 17
->'''Birthday:''' February 14 (Aquarius)
->'''Height:''' 170cm

!!Tropes associated with Caren:
* AloofAlly: In her first appearances, Caren frequently saves Lucia and co. from danger, but is not at all interested in being friendly or hang out with them.
* BeautyMark: Under her left eye.
* BigEater: She's known to eat large amounts of food... and stick others with the bill.
* BrokenBird: Hearing that her sister was captured and believing that Rina left her for dead drive Caren to be very cynical.
* DarkHorseVictory: Her introduction in the anime.
* DoesNotLikeMen: One scanslation had her say this in her introduction. Other translations, including the official one, had her say "I have no interest in ''little boys''", implying that it was the age of her hanger-on that made her dismiss him, not his gender. She later muses that love would be pointless anyway no matter who she was with, so whichever way she swings is up to reader discretion. In the anime, she ''does'' like men, but that has no bearing on the manga.
* CantCatchUp: Come the Michel arc, she's not nearly as powerful as the main trio, especially in the anime.
* DeadpanSnarker: She's always got a wry comment to spare.
* DemotedToExtra: Shipped off to go rebuild her country in the Michel arc.
* EarlyBirdCameo: Her introduction in the anime, where she wins the beauty contest out of nowhere.
* ImageSong: "Aurora no Kaze ni Notte" ("Riding on the Winds of the Aurora").
* IneffectualLoner: She tries to save Noel by herself and fails miserably, only effective when she's around the others.
* IWasJustPassingThrough: Caren pulls off a few rescues out of nowhere and just leaves.
* [[KnightTemplarBigBrother Knight Templar Twin Sister]]: You hurt Noel? Oh, and all the other princesses and all the civilians in their countries -- no, who cares about that. Noel is enough motivation to run at you in a rage.
* LetsGetDangerous: End of the manga with Noel and Coco.
* MysteriousWatcher: She hangs around in the shadows watching the main trio for a while before meeting them.
* NayTheist: Early on, she refuses to acknowledge Aqua Regina despite knowing full well that she exists. She's not outright denying it, but she does say that Aqua Regina never did anything for her or Noel.
* NiceJobBreakingItHero: By refusing the trio's help, she gets captured.
* PolarOppositeTwins: With Noel. Caren is sarcastic and jaded, Noel is gentle and soft-spoken. To emphasize this, they're actually from the North and South Poles.
* PurpleEyes: In her mermaid form.
* RapunzelHair: At one point, Tarou mistakes her for Sara because of it from a distance.
* RedOniBlueOni: With Noel. Caren's the red, being angry and loud in comparison.
* RegalRinglets: Huge curls in her long hair.
* SignificantBirthdate: Caren is a DefrostingIceQueen who says there's not much point to love if duty will always come first but becomes a ShipperOnDeck when she gets closer to the younger girls and starts to care about their love lives instead of [[RelationshipSabotage try to ruin them]]. Her birthday is Valentine's Day.
* WestCoastTeam: In the second arc, she, Noel, and Coco act as one.
* YouGottaHaveBlueHair: She has purple hair.
* YouShallNotPass: She, Noel, and Coco stall the Winged Beings in the second arc's finale with this.
!Noel
[[quoteright:250:https://static.tvtropes.org/pmwiki/pub/images/noel_3.png]]

!!Tropes associated with Noel:
* BeautyMark: Under her right eye.
* BlueOni: To Caren.
* {{Bookworm}}: Noted in episode 71.
* GenderBlenderName: Many translators thought her name was "Noelle" because they'd only seen men called "Noel."
* MeaningfulName: Because she's from the North Pole.
* {{Meganekko}}: Noel owns a pair of reading glasses she wears specifically to try and look smart.
* NiceGirl: Noel is kind and gentle to everyone she meets.
* OutOfFocus: Unlike Caren and Coco, she never gets her own episode in Pure.
* PolarOppositeTwins: With Caren. Caren is sarcastic and jaded, Noel is gentle and soft-spoken. To emphasize this, they're actually from the North and South Poles.
* RavenHairIvorySkin: She's the palest mermaid and has the darkest hair.
* YamatoNadeshiko: She's the quietest, most mature mermaid. Anime filler kind of ruins this characterization by making her go along with Caren's and Coco's zany schemes, though.

!!Tropes associated with Coco:

* {{Cloudcuckoolander}}: She's out there in the anime. Sometimes to the annoyance of the others.
* GenkiGirl: Her personality in the anime. She's more mature in the manga.
* HairOfGoldHeartOfGold: While she surrendered, it was out of a desire to help.
* HimeCut: Has this hairstyle. It's especially fitting considering that she ''is'' a princess.
* ItsAllMyFault: Feels guilty for not being able to appease Sara.
* MeaningfulName: Considering how she is associated with tropical islands...
* TheTease: Noted in episode 71.
* UndyingLoyalty: To her childhood friend Sara, especially in the manga. Coco ''never'' gave up on Sara and even allowed herself to be kidnapped so she could have a chance to try and help Sara.

[[caption-width-right:350:''"I want you to fill the seas with darkness as soon as possible, my prince."'']]
Sara first appears as a mysterious figure in Gackto's castle, stealing all his attention from the Dark Lovers and making them jealous. The truth is, Sara has been there all along, directing Gackto from behind the scenes. She does what she wants, when she wants, whether it helps or hinders Gackto's plans, and strings him along to agree with it by flirting and pulling rank, the exact same way he treats his Dark Lovers. Sara has had her heart broken in the past, and no longer believes in love, hope and freedom. Her objective now is to take revenge on all the world, but at times, what remains of her heart can get in the way - which Lucia and company will need to exploit if they want to summon Aqua Regina.

!!Tropes associated with Sara:
* BrokenBird: She's the way she is because she believed her lover abandoned her.
* ButNotTooEvil: The lyrics of the Italian version of her song say the ''exact opposite'' of what the original said, making her sound like a good guy. But also partially justified by the fact that either due to either laziness or genuine budget issues the Italian dub decided to recycle "Assoluto Amore" for Sara's successor Seira, your mileage may vary on how successful the execution is though... especially considering Seira's singing voice is the SAME as Sara's!
* DarkMagicalGirl: She's twenty-three, but it fits.
* DarkReprise: "Return to the Sea" reverses this.
* DisproportionateRetribution: She wants to destroy the world simply because she believes that a human she fell in love with abandoned her.
* EvilCostumeSwitch: Sara was originally an orange Mermaid Princess with more frills and less black.
* FaceHeelTurn: Before the beginning of the anime/manga.
* FanNickname: Black Sara.
* HeelFaceTurn: In the end of the Gackt arc, spoiled by merchandise.
* ImageSong: "Return to the Sea."
* InTheHood: Wears a veil to hide her face.
* IWasJustPassingThrough: She foils the Black Beauty Sisters' attack once, despite still being on the same side, and disappears soon after that.
* LastChorusSlowDown: The second half of "Return to the Sea" is slow-paced and nostalgic compared to the fast, almost angry tone of the first half.
* LoveMakesYouEvil ''and'' LoveRedeems. Sara was driven to desperation and wanted to take her pain out on the world for being betrayed, but in the end, [[spoiler:she realizes that it might have been for the greater good -- though she still doesn't learn that Tarou was ''set up'' -- and her acknowledgement that Gackt was always there for her leads her to confront him and bring him over to the good side too.]]
* ManBehindTheMan: To Gackto.
%%* MysteriousWatcher
* NoSell: She's immune to the other princesses' MagicMusic. While the anime presents it as it being [[MagicAIsMagicA hard-wired into their powers]] that mermaid songs can't harm other mermaids (without [[PlotHole explaining]] why Sara is able to hurt ''them'' with her music), the manga goes with the idea that Lucia and co. can't hurt Sara with their songs is because [[MyKungFuIsStrongerThanYours she's just that strong]].
* PaintItBlack: Her transformation from good (in orange) to evil (with black hair and, in the manga, a black dress) is the page image.
* PinocchioSyndrome: If Sara had only been human, we could have avoided all of this.
* RapunzelHair: Tarou considered it her DistinguishingMark.
* RebelliousPrincess: Sara was a selfish version of this, who wanted to abandon her country for love.
* RedemptionEqualsDeath: [[spoiler:Her end in the anime.]]
* RedemptionEarnsLife: [[spoiler:She is revived in the last episode. In the manga, she's still dead.]]
* SchrodingersCast: [[spoiler:She stays dead in the manga but revives in the nonsensical last episode of the anime.]]
* SealedGoodInACan: Her end in the manga.
* SpiritAdvisor: Takes this role in the beginning of the Michel arc.
* StarcrossedLovers: The series is full of this, manga especially, but her particular situation caused the entire story.
* VillainSong: "Return to the Sea" is hers.

->'''Birthday:''' December 19 (Sagittarius)

'''Major first arc spoilers here.''' Lucia, following Sara's last instructions, took the orange pearl to the Indian Ocean to create a new Orange Pearl Voice. The little girl, Seira, didn't fully emerge before Michel ambushed them and absorbed most of her life force. Now Seira is trapped as a spirit, much like Aqua Regina had been, inside the pearl, and much of the quest of the second arc focuses on getting back the pieces of her heart.
Tropes associated with Seira:
* BecomeARealBoy: Her arc is about regaining all her emotions and being born for real.
* BigDamnHeroes: Near the end of Pure, she rescues Lucia, Hanon, Rina, and Kaito from Michel. Unfortunately, she's taken hostage as a result.
* BrattyHalfPint: Though she gets a lot better when she learns more emotions.
* CharacterDevelopment: As she regains her lost emotions, she becomes kinder and more empathetic. In fact, she actually tries to reach out to Michel (the being who stole her emotions in the first place) because she can sense he's lonely and in pain.
* DamselInDistress: One of the main plotlines of the second season is about rescuing her from Michel. They even make it a point to remind us at the beginning of every other episode.
* HeroicSacrifice: But doesn't die.
* ImageSong: "Beautiful Wish" and "Birth of Love."
* ItsAllMyFault: Ends up blaming herself in part for all the pain Lucia went through to try and save her.
* KidAppealCharacter: She would logically be a baby, but she looks and acts like an elementary school-aged child. Definite kid appeal here.
* LackOfEmpathy: Through most of the Pure/Michel arc, Seira's heart is fragmented, and she only gains emotions after Lucia and company win them back. Until then, she's selfish and doesn't understand why Lucia is so sad about her failures and her amnesiac boyfriend.
* RapunzelHair: Like every mermaid.
* SomeoneHasToDoIt: Seira was born specifically to fill the void Sara left.
* SympathyForTheDevil: In relation to Michel.
* WhatIsThisFeeling: Throughout the season she learns what love, friendship, heartbreak, etc. feel like.
* YoungerThanTheyLook: She's only been born, but looks and acts in the 6-10 year old range.

[[caption-width-right:300:''"All these people are doing their best to find true love! I will not let you laugh at it!"'']]
Lucia is the [[MagicalGirl typical shoujo heroine]]: ditzy and lovestruck, but with a pure heart and a sense of love for her friends.
In the manga, she was raised to believe that she was a normal mermaid civilian, and lived on the surface as a human with her guardians, "sister" Nikora and "pet" Hippo (who is a penguin).
In the anime, she's always known that she is the Princess of the North Pacific Ocean, Pink Pearl Voice. Great, right... except for the "pink pearl" bit.
The pearl that gives her her power and is directly tied to her life force is gone; she gave it to a little boy to save his life when they were six. She gets it back from the boy, who turns out to be her classmate and crush Kaito, and realizes that she has to find the other ocean princesses and save the world. She's also expressly forbidden to confess her love or true identity to Kaito, but she's certain that she won't turn to foam if she finds some loophole. Little does she know that nobody turns to foam when they confess anyway...

* AwesomeMomentOfCrowning: End of the manga.
* ChangelingFantasy: Manga only.
* CovertPervert: Not as much as Hanon, though.
* CuteClumsyGirl: Lucia trips over things all the time.
* [[DangerousSixteenthBirthday Dangerous Thirteenth Birthday]]: Of course, Lucia's always known she's a mermaid, but in the manga she didn't find out she was a Mermaid ''Princess'' until her 13th birthday.
%%* TheDitz
* FearOfThunder: Possessed this trait.
%%* FirstKiss
* GenkiGirl: Easily the most energetic and positive character in the series.
* GirlishPigtails: Lucia has ditz/magical girl pigtails.
* GRatedDrug: She gets drunk off cola in the manga.
* HairDecorations: Wears two red ribbons while in human form.
* HairIntakes: Her hairstyle has two intakes that kinda look like cat ears.
* HairOfGoldHeartOfGold: She's blonde in mermaid form, in the anime, and in many manga pictures (it's very inconsistent), and she's a cute, kind and innocent princess.
* HeartSymbol: Cheesy hearts appear when Lucia performs her "Love Shower Pitch".
%%* TheHero
* HeroesWantRedheads: The manga's inconsistent colouring means that sometimes her boyfriend is the redhead, and sometimes ''she'' is.
* IdiotHair: She has a cowlick that stands prominently atop her head. This is reflective of her ditzy personality.
* ImageSong: "Koi wa Nandarou" ("What is Love?") and "Splash Dream." In the second season, "Mother Symphony" may also count.
* InterspeciesRomance: a pink Mermaid Princess who loves Kaito since her childhood.
* IWantSong: "Koi wa Nandarou" and "Splash Dream".
* KissingUnderTheInfluence: Literally in the manga, {{Bowdlerise}}d in the anime to be the result of a magic jewel.
* LockedOutOfTheLoop: Twice, but it doesn't make it past the second chapter of an arc.
* LoveTriangle: Lucia-Kaito-Michal.
* MeaningfulName: Lucia is Latin for 'light', and Nanami is Japanese for 'seven seas'.
%%* NewPowersAsThePlotDemands
* NonstandardCharacterDesign: Weird case with her being the main character and it's quite subtle. While the other mermaids have CurtainsMatchTheWindow which match their tail does she have HairOfGoldHeartOfGold with InnocentBlueEyes.
* NoPronunciationGuide: Her name Lucia is actually pronounced "Luchia", which leads to translations having that spelling of her name.
%%* ThePowerOfLove
* PinkHeroine: Her tail as a mermaid is pink, and her idol form outfit consists of a pink dress, pink gloves, and pink boots.
* PrincessesPreferPink: Her tail and shell-bikini as a mermaid are pink, and her idol outfits are entirely pink as well.
%%* ProphecyTwist
%%* PuppyDogEyes
* RagsToRoyalty: She's a Sleeping Beauty in the manga and a Snow White in the anime.
* RescueRomance: Lucia saved Kaito when they were children and they've remembered each other ever since. [[spoiler:In the manga's final bonus chapter, it turns out that he also saved her at the same time when she was struggling to keep him afloat.]]
* SayItWithHearts: Not as often as Hanon, but a lot, including her "Love Shower Pitch."
* SayMyName: '''KAITOOOOOOOOOOOOOOOO!'''
%%* ThisLoserIsYou
* TownGirls: The Neither to Hanon's Femme and Rina's Butch.
* TrademarkFavoriteFood: A mermaid who actually eats seafood, for once.

[[caption-width-right:250:''"I know how to attract the guys, and I'll ♥ teach ♥ you! ♥"'']]
Hanon is a flirty, carefree, all-around girly-girl that befriends Lucia on her first day of school. She's more serious than she looks, however, and has been watching Lucia for days and confronts her with her true identity at the end of the first chapter. Hanon is actually the Princess of the South Atlantic Ocean, otherwise known as Aquamarine Pearl Voice. With her strength and happy nature, she makes a great first ally for Lucia, even though they're always at each other's throats -- in particular, Hanon doesn't approve of Lucia dating Kaito at first, even though she's all over a human man, who, at that, happens to be her own ''teacher''. Again, though, despite her peppy, fluffy, hypocritical image, Hanon feels tremendous guilt for the fate of her kingdom, which was besieged with her as the only apparent survivor.

!!Tropes associated with Hanon:
* AsYouKnow: Hanon and Nicola like to go on about the rules of the mermaid world. Lucia usually actually doesn't know this. She's just that dense (or overprotected).
* TheChick: "Flirty, carefree, all-around girly-girl"
* CovertPervert: Hanon is a hormonal teenager, all right.
* DeclarationOfProtection: What "Ever Blue" is about; protecting the ocean, your loved ones, etc.
* DoomedHometown: Like most of the others, she fled a ruined homeland.
* FirstKiss: Something she's dreamt about for ages.
* FirstNameBasis: Hanon thrusts it upon everyone she meets.
* HotForTeacher: Her first crush being Tarou Mitsuki.
* ImageSong: "Ever Blue" and "Mizuiro no Senritsu" ("The Aquamarine Melody").
* IWantMyBelovedToBeHappy: Eventually decides this despite how much it hurts her for Tarou to be in love with someone else.
* TheLancer: She likes disagreeing with Lucia.
* QuirkyHousehold: Once Hanon moves in, the Shinju-yu/Pearl Piari becomes this instantly.
* SatelliteLoveInterest: She tends to go for guys who she just thinks are cute. Tarou is one of these; as crushed as she is to learn that he's [[RealityEnsues interested in people his own age]], she eventually gets over it when he leaves.
* SayItWithHearts: Every other sentence.
* ThereIsAnother: A lot of Hanon's subjects did survive.
* TomboyAndGirlyGirl: She's the girly one to Rina.
* TownGirls: The Femme to Lucia's Neither and Rina's Butch.
* {{Tsundere}}: Towards Nagisa. Since he's not her usual type, she tries her best to ignore that he's there.
%%* UmbrellaOfTogetherness
* YouGottaHaveBlueHair: Most people in the show, actually, but Hanon deserves a mention for literal blue hair.

[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/rina_31.png]]
[[caption-width-right:350:''"It doesn't matter. Your true nature will come out soon enough."'']]
The standoffish transfer student that Lucia decides to befriend on a whim, Rina is idolized by her classmates as "cool" because she spends most of her time brooding and making the occasional sarcastic remark. She, too, is a princess: Green Pearl Voice from the North Atlantic Ocean. Rina acts as an emotional pillar for her friends, but she herself has issues that need to be dealt with. Even more so than Hanon, she carries a measure of guilt about her escape; after being forced to leave their countries behind, Rina and her friend, Princess Noel from the Arctic Ocean, were ambushed by Gackto and only Rina got away. Despite what she thinks of herself for this, she's a strong and loyal friend of her team.

!!Tropes associated with Rina:
* AllLoveIsUnrequited: Her crush on Kaito in the anime.
* AloofAlly: Didn't last long.
* {{Bifauxnen}}: [[Main/TakeOurWordForIt You couldn't tell by looking at her, but apparently, she is]]. She wears the boys' uniform, and Lucia and Hanon's first reaction to seeing her in the anime is "That was a girl... ''right''?".
* BokeAndTsukkomiRoutine: Rina wants to be a comedian in the anime. In one episode and its preview, she manages a decent routine with Lanhua.
* TheComicallySerious: Particularly in the anime, where she's still serious but has things added to her character like being obsessed with plasma [=TVs=] and wanting to be a comedian.
* CustomUniform: Rina wears the boys' uniform for no apparent reason.
* DontSaySuchStupidThings: On both the giving and receiving ends.
* DoomedHometown: She fled her home like many of the others when Gackt came along.
* FunTShirt: Her "It's cool" shirt with the penguin on it.
* [[SheIsNotMyGirlfriend He Is Not My Boyfriend]]: Denies having anything going on with Hamasaki for ages.
* HeroWithBadPublicity: Gets this from Caren and the rest of the Antarctic Ocean during the first season. While Noel in fact [[HeroicSacrifice sacrificed herself]] to give her a chance to escape from Gaito, Caren's kingdom believes that Rina [[DirtyCoward abandoned Noel to save her own hide]].
* HimeCut: Fits with her status as a miko.
* ImageSong: "Star Jewel" and "Piece of Love."
* LayingOnAHillside: Rina does this a lot in the anime, especially in ''Pure'', when they had to reuse animation all the time and thus shots and whole chunks of scenes were repeated.
* {{Miko}}: In the manga, she works for a shrine to a spirit both mermaids and humans venerate.
* MysteriousWatcher: For one episode, before she turns out to be a Mermaid Princess herself.
* NewTransferStudent: Apparently has a lot of rumours about her when she shows up, though we don't actually hear any.
* [[NonActionGuy Non Action Song]]: "Piece Of Love" from ''Pure''.
* {{Otaku}}: In the anime, she's given such an obsession with plasma [=TVs=].

[[quoteright:225:https://static.tvtropes.org/pmwiki/pub/images/images_2615.jpg]]
[[caption-width-right:225:''"Who said I'm joining you?"'']]
Brash, bitter and initially unkind, Caren, otherwise known as Purple Pearl Voice and the Princess of the Antarctic Ocean, shows up mid-way through the first arc to rescue Lucia and company a few times. That doesn't, as she makes clear, mean that she plans to join them or become their friend. Caren is the fraternal twin sister of Noel, and as such, has a deep personal grudge against Rina for escaping when the other princess did not. She takes it upon herself to rescue her sister ''alone'', and only when her brazen attempt gets her captured and the heroes rescue her but Noel sacrifices herself again does Caren realize that Rina wasn't selfish at all. She never quite integrates herself into the team for good, leaving more than once after the job's done, but is important enough to be listed with the main cast for the second half of the first arc/season.

!!Tropes associated with Caren:
* AloofAlly: In her first appearances, Caren frequently saves Lucia and co. from danger, but is not at all interested in being friendly or hang out with them.
* BeautyMark: Under her left eye.
* BigEater: She's known to eat large amounts of food... and stick others with the bill.
* BrokenBird: Hearing that her sister was captured and believing that Rina left her for dead drive Caren to be very cynical.
* DarkHorseVictory: Her introduction in the anime.
* DoesNotLikeMen: One scanslation had her say this in her introduction. Other translations, including the official one, had her say "I have no interest in ''little boys''", implying that it was the age of her hanger-on that made her dismiss him, not his gender. She later muses that love would be pointless anyway no matter who she was with, so whichever way she swings is up to reader discretion. In the anime, she ''does'' like men, but that has no bearing on the manga.
* CantCatchUp: Come the Michel arc, she's not nearly as powerful as the main trio, especially in the anime.
* DeadpanSnarker: She's always got a wry comment to spare.
* DemotedToExtra: Shipped off to go rebuild her country in the Michel arc.
* EarlyBirdCameo: Her introduction in the anime, where she wins the beauty contest out of nowhere.
* ImageSong: "Aurora no Kaze ni Notte" ("Riding on the Winds of the Aurora").
* IneffectualLoner: She tries to save Noel by herself and fails miserably, only effective when she's around the others.
* IWasJustPassingThrough: Caren pulls off a few rescues out of nowhere and just leaves.
* [[KnightTemplarBigBrother Knight Templar Twin Sister]]: You hurt Noel? Oh, and all the other princesses and all the civilians in their countries -- no, who cares about that. Noel is enough motivation to run at you in a rage.
* LetsGetDangerous: End of the manga with Noel and Coco.
* MysteriousWatcher: She hangs around in the shadows watching the main trio for a while before meeting them.
* NayTheist: Early on, she refuses to acknowledge Aqua Regina despite knowing full well that she exists. She's not outright denying it, but she does say that Aqua Regina never did anything for her or Noel.
* NiceJobBreakingItHero: By refusing the trio's help, she gets captured.
* PolarOppositeTwins: With Noel. Caren is sarcastic and jaded, Noel is gentle and soft-spoken. To emphasize this, they're actually from the North and South Poles.
* PurpleEyes: In her mermaid form.
* RapunzelHair: At one point, Tarou mistakes her for Sara because of it from a distance.
* RedOniBlueOni: With Noel. Caren's the red, being angry and loud in comparison.
* RegalRinglets: Huge curls in her long hair.
* SignificantBirthdate: Caren is a DefrostingIceQueen who says there's not much point to love if duty will always come first but becomes a ShipperOnDeck when she gets closer to the younger girls and starts to care about their love lives instead of [[RelationshipSabotage try to ruin them]]. Her birthday is Valentine's Day.
* WestCoastTeam: In the second arc, she, Noel, and Coco act as one.
* YouGottaHaveBlueHair: She has purple hair.
* YouShallNotPass: She, Noel, and Coco stall the Winged Beings in the second arc's finale with this.
!Noel

!!Tropes associated with Noel:
* BeautyMark: Under her right eye.
* BlueOni: To Caren.
* {{Bookworm}}: Noted in episode 71.
* GenderBlenderName: Many translators thought her name was "Noelle" because they'd only seen men called "Noel."
* MeaningfulName: Because she's from the North Pole.
* {{Meganekko}}: Noel owns a pair of reading glasses she wears specifically to try and look smart.
* NiceGirl: Noel is kind and gentle to everyone she meets.
* OutOfFocus: Unlike Caren and Coco, she never gets her own episode in Pure.
* PolarOppositeTwins: With Caren. Caren is sarcastic and jaded, Noel is gentle and soft-spoken. To emphasize this, they're actually from the North and South Poles.
* RavenHairIvorySkin: She's the palest mermaid and has the darkest hair.
* YamatoNadeshiko: She's the quietest, most mature mermaid. Anime filler kind of ruins this characterization by making her go along with Caren's and Coco's zany schemes, though.

* {{Cloudcuckoolander}}: She's out there in the anime. Sometimes to the annoyance of the others.
* GenkiGirl: Her personality in the anime. She's more mature in the manga.

* ItsAllMyFault: Feels guilty for not being able to appease Sara.
* MeaningfulName: Considering how she is associated with tropical islands...
* TheTease: Noted in episode 71.

Sara first appears as a mysterious figure in Gackto's castle, stealing all his attention from the Dark Lovers and making them jealous. The truth is, Sara has been there all along, directing Gackto from behind the scenes. She does what she wants, when she wants, whether it helps or hinders Gackto's plans, and strings him along to agree with it by flirting and pulling rank, the exact same way he treats his Dark Lovers. Sara has had her heart broken in the past, and no longer believes in love, hope and freedom.

'''Major first arc spoilers here.''' Lucia, following Sara's last instructions, took the orange pearl to the Indian Ocean to create a new Orange Pearl Voice. The little girl, Seira, didn't fully emerge before Michel ambushed them and absorbed most of her life force. Now Seira is trapped as a spirit, much like Aqua Regina had been, inside the pearl, and much of the quest of the second arc focuses on getting back the pieces of her heart.
Tropes associated with Seira:
* BecomeARealBoy: Her arc is about regaining all her emotions and being born for real.
* BigDamnHeroes: Near the end of Pure, she rescues Lucia, Hanon, Rina, and Kaito from Michel. Unfortunately, she's taken hostage as a result.
* BrattyHalfPint: Though she gets a lot better when she learns more emotions.
* CharacterDevelopment: As she regains her lost emotions, she becomes kinder and more empathetic. In fact, she actually tries to reach out to Michel (the being who stole her emotions in the first place) because she can sense he's lonely and in pain.
* DamselInDistress: One of the main plotlines of the second season is about rescuing her from Michel. They even make it a point to remind us at the beginning of every other episode.
* HeroicSacrifice: But doesn't die.
* ImageSong: "Beautiful Wish" and "Birth of Love."
* ItsAllMyFault: Ends up blaming herself in part for all the pain Lucia went through to try and save her.
* KidAppealCharacter: She would logically be a baby, but she looks and acts like an elementary school-aged child. Definite kid appeal here.
* LackOfEmpathy: Through most of the Pure/Michel arc, Seira's heart is fragmented, and she only gains emotions after Lucia and company win them back. Until then, she's selfish and doesn't understand why Lucia is so sad about her failures and her amnesiac boyfriend.
* RapunzelHair: Like every mermaid.
* SomeoneHasToDoIt: Seira was born specifically to fill the void Sara left.
* SympathyForTheDevil: In relation to Michel.
* WhatIsThisFeeling: Throughout the season she learns what love, friendship, heartbreak, etc. feel like.
* YoungerThanTheyLook: She's only been born, but looks and acts in the 6-10 year old range.
