! Manaka Mukaido
-->Voiced by Creator/KanaHanazawa %%Creator/MichelleRuff

Hikari's ChildhoodFriend who is clumsy and prone to crying. As a result of him constantly protecting her as a child, she is somewhat emotionally dependent on him. It's implied that she has feelings for Tsumugu.

* AlliterativeName
* ChildhoodFriends: With Hikari, Chisaki and Kaname.
* CuteClumsyGirl
* DeclarationOfProtection: To Hikari in episode 4. It's part of her CharacterDevelopment, as Manaka seems to be slowly gaining confidence in herself.
* [[spoiler:DeepSleep: Enters hibernation after crashing into the Ojoshi-sama graveyard. Hikari finds and takes her up to the surface, a week passes but she still does not wake up until the end of episode 20.]]

* FragileFlower: A very emotional fragile young girl.
* HairDecorations: She has a small white decorations that resemble wings in her hair.
* [[spoiler:HeroicSacrifice: Sacrifices herself to the Sea God in Akari's place. Manaka lost her Ena and the ability to love anyone because she refused to accept her role as the Ojoshi-sama, which delayed the cooling of the world, a process accelerated after she was brought back to the surface. In Episode 25, she retrieves both attributes from Miuna, who subsequently becomes the sacrifice.]]

** In a cruel twist, episode 22 reveals that [[spoiler: she has completely become this, after the sea god took away her ability to love anyone]].
* [[spoiler: OlderThanSheLooks: Just like Hikari and Kaname, she hasn't aged at all.]]
* SilkHidingSteel: In a sense. Manaka's sensitive nature (and her tendency to cry easily) hides a very strong will.
* TaremeEyes

! Tsumugu Kihara
-->Voiced by Creator/KaitoIshikawa
[[caption-width:350:[[spoiler:[[labelnote:Click here to see his post-TimeSkip appearance]][[/labelnote]]]]]]

A boy from the surface who attends Mihama Junior High. Tsumugu first comes into contact with the sea-dwelling kids when he accidentally fishes Manaka out of the water. He shows a strong interest in Shioshishio's culture and eventually befriends the group when working on a festival doll with them. He lives with his grandfather Isamu, [[spoiler: who is in fact a merman himself]].

* AccidentalPervert: Tsumugu walks in on a half naked Chisaki. PlayedForDrama.
* [[spoiler: AllLoveIsUnrequited: He is in love with Chisaki and she actually returns these feelings but she is in denial about them.]]
* [[spoiler:AnchoredShip: Is this with Chisaki for many years. They both love each other but Chisaki is in denial about her feelings and Tsumugu is hesitant in making any moves.]]
* {{Bishounen}}
* BrutalHonesty: He doesn't bother mincing his words. It seems to be a double-edged sword - while this trait has helped facilitate Manaka's CharacterDevelopment, it didn't serve him well when he confronted Chisaki regarding the latter's feelings for Hikari. It's arguably Tsumugu's biggest asset ''and'' flaw, and he can unintentionally come off as an arrogant know-all, as Chisaki points out in episode 24.
* [[spoiler: CanNotSpitItOut: He has been in love with Chisaki for years, but doesn't approach her about it since she still has some feelings for Hikari.]]
** [[spoiler: LoveConfession: In episode 23 he confess to Chisaki, at first accidentaly and later he gives her a proper confession.]]
* CityMouse: Was this when he was younger. He lived in the city with his parents prior to running away live with his grandfather.
* FirstNameBasis: With Hikari and Kaname. He calls the girls by their last names.
** He starts calling Chisaki and Miuna (and presumably Sayu) by their first name [[spoiler: after the TimeSkip. Notably, he still addresses Manaka by her last name.]]
* {{Foil}}: To both Hikari and Kaname. It's more obvious with Hikari, with Tsumugu's quiet wisdom contrasting with Hikari's impulsive yet well-intentioned actions. With Kaname, it's slightly more complex: Both boys tend to hide their true feelings and try to be mature- Kaname conceals his behind a smile, while Tsumugu does the same by maintaining a stoic front. [[spoiler:They also differ in how the act with regard to Chisaki- Kaname actively tries to get Chisaki's attention, while Tsumugu is rather passive in comparison, preferring to wait it out and let Chisaki sort out her feelings.]]
* [[spoiler:HeIsAllGrownUp: After the TimeSkip.]]
* [[spoiler:InnocentCohabitation: With Chisaki, after the TimeSkip. They live together with his grandfather, but since Isamu is currently in the hospital, they're alone.]]
** [[spoiler: They are later joined by Kaname.]]
* LoveTriangle: Hikari likes Manaka who likes Tsumugu, but his feelings towards her are ambiguous.
** There are hints that he likes Chisaki and Kaname perceives him as a romantic rival in gaining her affections. [[spoiler:The second cour confirms that Tsumugu has been deeply in love with Chisaki all along. He wins the LoveTriangle too.]]
** [[spoiler: He never thought of Manaka in a romantic light and she confessed to him that the one she loved was Hikari.]]
* MommyIssues: We don't know what happened, but it seems he doesn't get along with his mother. [[spoiler: Episode 23 reveals that his mother and father used to live with Tsumugu's grandfather by the sea. However, they hated the sea and abandoned it in favor of the city. Tsumugu ran away from his parents to reunite with his grandfather.]]
* NiceGuy
* [[spoiler: OfficialCouple: With Chisaki, after they confirm and accept their feelings for each other.]]
* RealMenCook: He knows how to cook, as evidenced in episode 4.
* TallDarkAndHandsome:[[spoiler: Especially after the TimeSkip.]]
* TheStoic: Usually.
** NotSoStoic: He laughs his head off in episode 3. It's quite a sight to behold.
* TheQuietOne: He reveals to Miuna that his naturally quiet and emotionally distant nature bothers him, especially since the four Shioshishio kids express themselves more freely that he does. It's implied that he believes it to be the reason why he never fully integrated into the tight circle of Hikari, Manaka, Chisaki and Kaname in middle school.
* ObliviousToLove: He doesn't seem to notice Manaka's feelings for him. [[spoiler: Or he may have noticed her affections as evidenced in episode 23 but did not believe they were done out of romantic love and it was because she was curious of the surface instead, Manaka also later confessed to him that she was in love with Hikari]]
* [[spoiler: SecondLove: He is Chisaki's.]]
* ShipTease: Has quite a bit of this with Chisaki even though their relationship is quite removed from the rest of the LoveDodecahedron drama in the series.
** [[spoiler:Until the second cour rolls around where the ShipTease is turned up and it is revealed that the two have been in love with each other all along but various circumstances kept them from getting a RelationshipUpgrade.]]
* [[spoiler:PatientChildhoodLoveInterest: With regard to Chisaki, though they were a bit older than most when the trope came into effect.]]
* RaisedByGrandparents: He went to live with his grandfather on his own volition at the age of 9.
* [[spoiler:RomanticFalseLead: At first it seems that he is going to be Hikari's rival as a contender for Manaka's affections, but he never shows any kind of romantic interest on her and ends up developing feelings for Chisaki instead.]]
* [[spoiler:UnresolvedSexualTension: Has this with Chisaki in spades.]]
* [[spoiler:VictoriousChildhoodFriend: To Chisaki.]]
* WhatTheHellHero: Essentially invokes this trope in episode 9 when he tells Chisaki that she should stop trying to change herself. She doesn't really take it well, and accuses him of not understanding her.
** He was telling her to not change herself for all the wrong reasons - a boy.
* WhenHeSmiles
* WiseBeyondHisYears

* [[spoiler:BreakTheCutie: If having all her friends and family go into a DeepSleep wasn't enough for the poor girl, she has a small breakdown after Tsumugu's grandfather (who [[ParentalSubstitute more or less]] [[HappilyAdopted adopted her]] after everybody else was gone) almost dies and has to go into emergency surgery, terrified he was going to die and leave her, too.]]

* HeterosexualLifePartners: With Manaka.
* [[spoiler:InnocentCohabitation: With Tsumugu, after the TimeSkip. They live together with Tsumugu's grandfather, but since Isamu is currently in the hospital, they're alone.]]
** [[spoiler: They are later joined by Kaname.]]
* IWantMyBelovedToBeHappy: She would rather have Hikari and Manaka get together than trying to get Hikari herself.
** [[spoiler: She has also been in love with Tsumugu for years but felt guilty in pursuing a relationship with him because as fas as she knew Manaka liked him and she didn't want to let go of her feelings for Hikari, since it would mean that she had changed.]]

* LoveTriangle: In the first half, Chisaki likes Hikari but he is in love with her best friend, Manaka. There were also hints of a LoveTriangle between Tsumugu, Chisaki and Kaname in the first half [[spoiler: which were confirmed in the second half. It is revealed that she had some feelings for Tsumugu five years ago, which developed further into love during the time they spent together. However, she is constantly in denial about it because she cannot believe that she fell in love with him within the span of five years while she knew Hikari since she was born and she is aware that Manaka likes Tsumugu as well.]]
** [[spoiler: Although it turns out later that Manaka's interest in Tsumugu was actually based on her admiration for the surface and she was really in love with Hikari.

* StrongFamilyResemblance: She is a younger version of her mother!
* [[spoiler:SurvivorGuilt: She feels guilty for being able to go on with her life, growing up, falling in love and such while everyone else she knew were all hibernating. She feels that if she doesn't cling to her past self, and her past feelings, she will betraying her family and friends.]]
* TheResenter: Chisaki hates herself for not supporting Hikari and Manaka's relationship as wholeheartedly as she'd like to. This is, in part, due to her feelings for Hikari.

! Kaname Isaki
-->Voiced by Creator/RyotaOhsaka

Friends with Hikari, Chisaki and Manaka. Kaname is an perceptive, easygoing boy who is Chisaki's chief confidant. He is polite, but straightforward, and seems to have a mischievous streak.

* BeneathTheMask: A lot of his actions in the series show that Kaname isn't as mature as he tries to be.
* BigBrotherMentor: He's not actually related to any of them, but Kaname's the most mature of the sea-dwelling kids, and is usually the one (among the four of them) to give advice to the others or ask a thought-provoking question.
* {{Bishounen}}
* BishieSparkle: In episode 7.
* TheCharmer: His generally easygoing demeanor earns him a the admiration of one of his female classmates. He's not afraid to use this to his advantage, if episode 7 is any indication.
* ChildhoodFriends: With Hikari, Manaka, and Chisaki.
* TheComicallySerious: Casually strolls to a cafe owner while nude and asks him what day it is.
* CruelToBeKind: His reasons for [[spoiler:forcing Hikari to confess to Manaka]] included wanting the four of them to let it all out and [[spoiler:hibernate]] without any regrets. [[spoiler:The other main reason stemmed from his jealousy towards Tsumugu- and to a lesser extent- Hikari. It backfires horribly, and Kaname is left lamenting on how he, too tried "his best".]]
* [[spoiler: CruelMercy: He was not planning on saving Tsumugu. Originally, he wanted to leave him to [[MurderTheHypotenuse die since Tsumugu was also in love with Chisaki and then Kaname would be rid of any competition]]. He decided to save Tsumugu only so that he could impress Chisaki but it failed miserably because he fell into the sea instead. Whether he actually meant this or was saying it out of bitterness towards Tsumugu remains to be seen.]]
* DeadpanSnarker: He's got a bit of a mean streak and is not above making subtle jabs at his friends. See the example below and keep in mind that Chisaki likes Hikari. It takes place when the four kids are discussing Akari's boyfriend and land-dwellers in general.
-->'''Hikari:''' Chisaki, your taste in guys sucks.
-->'''Kaname''' ''(nonchalantly)''''':''' Ain't that the truth.
-->''Chisaki looks away, blushing.''
* [[spoiler:DeepSleep: Like most of the Shioshio residents.]]
* DoggedNiceGuy: There are hints that he might like Chisaki.
** [[spoiler:LoveConfession: In episode 10.]]
* FirstNameBasis: With Chisaki, Hikari and Manaka and later with Tsumugu.
* GreenEyedMonster: Eventually shows signs of this towards [[spoiler: Tsumugu, when Chisaki reconciles with him. And the envy grows as their relationship seems to improve.]]
* HeterosexualLifePartners: With Hikari.
* [[spoiler:InnocentCohabitation: After he wakes up he goes to live with Chisaki and Tsumugu.]]
* [[spoiler:MaybeEverAfter: With Sayu, after her confession he says that he will start looking at her as a girl his age and the ending does imply that they may end up together soon.]]
* [[spoiler:LikesOlderWomen: After the TimeSkip he made sure to tell Chisaki that since she has gotten older than him now he prefers older women.]]
* LoveTriangle: He likes Chisaki but she is in love with Hikari.
** Tsumugu is also hinted to like Chisaki, this causes Kaname to perceive him as a romantic rival and act incredibly jealous whenever the two interact. [[spoiler: He loses the LoveTriangle after realising that Chisaki has loved Tsumugu all along.]]
* [[spoiler: MurderTheHypotenuse: Apart from Kaname himself, Tsumugu is also in love with Chisaki. Kaname grows increasingly jealous of Tsumugu becoming closer to her. In episode 13, Kaname thought about leaving Tsumugu to die as a way of removing the competition.]]
* [[spoiler:NakedOnRevival: Just like with Hikari, only he woke up alone and had to walk into town nude.]]
* [[spoiler:OlderThanHeLooks: Like Hikari, he hasn't aged after waking up after the TimeSkip.]]
* OnlySaneMan: He is the most level-headed in the group, and he is the only one who can converse with the land people normally. He is also the one least likely to be swayed by prejudices of preferences, be it the conflict between the people of the land and sea or the LoveDodecahedron involving his best friends. [[spoiler:Later, however, Kaname's neutral fašade breaks once when Chisaki speaks bitterly of Tsumugu. The fact that Tsumugu is able to stir passionate emotion in Chisaki- something Kaname has never been able to do- incurs Kaname's jealousy, and his bitterness increases after the TimeSkip, as he's aware of the fact that he's rapidly losing any chance he's ever had of getting together with Chisaki.]]
* PatientChildhoodLoveInterest: Is trying to be this to Chisaki. [[spoiler:It doesn't work and he soon figures out that she has been in love with Tsumugu all along.]].
* [[spoiler: StepfordSmiler]]
* UndyingLoyalty: Shown when he convinces Sayu to apologise to Hikari for vandalising the Ofunehiki.
** [[spoiler: He tells Chisaki that no matter what happens, he will always love her.]]
* [[spoiler:UnluckyChildhoodFriend: To Chisaki.]]
* WiseBeyondHisYears: Very insightful despite his sociable nature. This aspect of his character is especially prominent when he is interacting with Chisaki and -to a lesser extent- Hikari.
