%%* HeroesWantRedheads

* MultiethnicName: Her family name is Japanese, but her given name decidedly isn't (despite being half French, "Frederica" is a Germanic name; the correct French version of this name is "Frédérique").

* GirlsAreReallyScaredOfHorrorMovies: Averted. She's actually bored by a lot of them.

* BuxomBeautyStandard: Of course she's far from being the largest, but she wears baggy clothing hiding the assets she has. The artwork for her ImageSong brings more attention to them, and in case anyone did not notice them before, she's using her bust to hold down pages of a music book.

* HiddenBuxom: While she's sexy regardless, she's surprisingly top-heavy in some cards, almost on par with the likes of Miku, Kako, Mizuki and even Airi. It's not as well-pronounced as the previous examples, however.

* LovableSexManiac: Though she doesn't specifically speak about sex, her constant innuendo with kissing is an allusion for it. She relentlessly hits on Staff-san during her DramaCD. However [[spoiler:the ending to the same skit reveals she might have never been kissed before, let alone been in a sexual relationship.]]

* OlderThanTheyLook: Due to being so short - she's a working adult.

* [[HeroesLoveDogs Heroines Love Dogs]]: One S Rare card, Rose-Colored Bride, has two costumed dogs.

* DeadpanSnarker: Has her moments.

* LovableSexManiac: Though she doesn't specifically speak about sex, her constant innuendo with kissing is an allusion for it. She has mild degrees of AnythingThatMoves, as she relentlessly hits on Staff-san during her DramaCD. However [[spoiler:the ending to the same skit reveals she might have never been kissed before, let alone been in a sexual relationship.]]

* FlowerMotifs: Almost of her idol outfits have a roses theme to them. Her first SSR card in Starlight Stage is named "''Rose'' Fleur".

[[spoiler:In chapter 4 of the "Near to You" event commu, Momoka considers Arisu not as a WorthyOpponent, but as a mutual friend with the same goal of bettering themselves in their youth.]] See "Friendly Rivalry" under Arisu's entry for more details.

%% * HairOfGold

* ImageSong: ''La Vie en Rose'' and ''Ai no Sanka''
* TheOjou: She's a ProperLady type, wealthy, has butlers, drinks tea etc. She's from a wealthy upbringing, not unlike Iori in the 765PRO games. As her interview proves, she's relatively out of touch with how common folks live, but is open to trying out new things. Becoming Ojou-chama is kinda hard for Momoka, sacrificing her time to enjoy her "childish" life as the other kids do for things like tea time and stuff (though she had it again, seen in Hi-Fi Days commu, sort of). On ''Magic Hour'' SP 17, she said when she grows up as an actual adult, she wanted to ride a bicycle and go as far as she can...because her parents won't let her ride a bike for safety reasons.

* SleepCute: Three occurences, one cute sleeping face. She tries to stay awake all night.. but eventually fallen asleep instead, seen on two [[Manga/TheIdolmasterCinderellaGirlsTheater Yonkoma]] chapters (#305 and #1029) and episode 13 of Theater Anime's second season.

* TheTeam: While she's not in the original LMBG unit, she's part of the group that sings the song ''Hi-Fi Days'' in Starlight Stage, along with Chie Sasaki, Nina Ichihara, Kaoru Ryuzaki, and Miria Akagi.

* BestFriend: While far from antisocial or unfriendly, Asuka's {{Chuunibyou}} personality and mannerism made it difficult for other idols to approach her.

The fandom greatly approved this {{Chuunibyou}} pairing, which culminated in a duet unit known as ''Dark Illuminate'' with their own signature song, ''Souyoku no Aria''.

* BewareTheNiceOnes: In her "The Seven Mysteries of Sacred Slipper Academy" S Rare+, she looks more menacing than she usually does... although she doesn't cross {{yandere}} territory. This might be a case of [[PlayingAgainstType playing against type]]

* {{Sarashi}}: Wears it on her initial ''Rare +'' card.

* YoungerThanTheyLook: Many didn't realize that she's actually still 13 years old, partly due to her traditional Japanese attire she wears often. Doesn't help that her general singing voice makes her sounds 10 years older than she is, best exemplified in ''Onna no Michi wa Hoshi no Michi''.

* AchievementsInIgnorance: Most people when suffered same fate as her would already went DrivenToSuicide or start thinking about {{Revenge}} and yet, she unaware that [[BadassPacifist keep going through her live & took every misfortune & blame from anything & anyone without any plan to]] [[FaceHeelTurn become bad]] [[BadassPacifist is admirable in itself.]]

* ImageSong: ''Tani no Soko de Saku Hana wa''

This is '''[[TroublingUnchildlikeBehavior obviously not normal for 13 years old.]]'''

* TheJinx: Sometimes interpreted as such.
* ThePollyanna: She tries so hard to be one. Things have gotten a lot better since meeting the Producer.

* CanNotSpitItOut: Has tried to confess her feelings to the Producer, but always gets cold feet.

* CharacterDevelopment: Not as you'd expect. At first, she feels like her whole personality needs to be fixed, but she slowly starts to show what little she can do.
* CoverVersion: ''Brave Heart'', the evolution theme song of ''Anime/DigimonAdventure'' for the Starlight Stage and ''Anime/DigimonAdventureLastEvolutionKizuna'' collaboration.

* DamageIncreasingDebuff: Her ''S Rare+'' card has an incredibly powerful effect on opposing idols. Easily one of the deadliest in this area.

* ImageSong: ''Mori no Kuni Kara''

* LonerTurnedFriend: Finding friendship with several idols. She becomes close with fellow social outcasts, Syoko Hoshi and Koume Shirasaka. Mirei Hayasaka always tries to lend her support whenever Nono becomes too afraid of something, and Mayu Sakuma likes to timeshare Nono's hiding spot because it's under the Producer's desk... although Nono is understandably [[{{Yandere}} a bit wary of Mayu]].

* NervousWreck

* PerformanceAnxiety: Will not look at the camera or audience if she can help it. This is reflected in the anniversary concerts, where her seiyuu looks anywhere but the audience most of the time during songs.

* ScrewThisImOuttaHere: Tries to invoke it on her idol career, but stops herself when panicking about all the bad things that could happen if she quits. Plus the Producer is always there to comfort her enough to keep going.

* StoneWall: Her ''Rare+'' card. Has high defense and debuffs the opponent's attack value.

* TookALevelInCheerfulness: Subverted. For awhile it seemed comics revealed a Nono was becoming more outgoing and confident, though she kept the DullEyesOfUnhappiness. Then a {{Yonkoma}} featuring her in a squirrel costume, revealed she's ''REALLY'' putting a lot of effort in faking to become normal.

* {{Foil}}: Serves as one to her partner in crime, Nana Abe. Both Shin and Nana were insecure of their age in the occupation mostly filled with youthful girls, and both finding ways to cope with the feel by dressing and acting cutesy as if they were younger. The difference is that while Nana refuses to reveal her age and enforces herself and everyone else in her [[{{Chuunibyou}} self-invoked childish fantasy]] and restricting herself into more cutie and childish roles, Shin has no problem looking more mature if she had to and is professional enough to not let her insecurity get the best of her. Shin also doesn't mind revealing her age, while Nana kept her age secret all the time, which hints that she might be much older than the rest of the production, Shin included. Lastly, while both Nana and Shin prefer cutesy theme for their costumes, Nana's costumes in her cards is more youthful and whimsical and less revealing than Shin, while Shin prefers to look a lot more curvaceous and elegant, while still being in tune of her cutesy preference.

* TalkingInYourSleep: Caused a misunderstanding that made her grandparents think the Producer was a pervert.

* ButtMonkey: Riamu ended up in the butt of many jokes, and her apparent bad luck doesn't seem to help her either.
* BuxomBeautyStandard: One of her voice lines suggests she is tied with Takumi for the second-largest bust measurement in the cast and she's aware her chest is one of her main appeals as a model.

* ImageSong: ''OTAHEN Anthem''
* HospitalHottie: Her idol form. One of her lines reveals she dropped out of vocational school before becoming one.

* {{Otaku}}: She's an idol otaku herself, and is very knowledgable about idol fans and how they work. Naturally, she also behaves like one every now and then. Her antics and demeanor came from the ''[[https://menhera.bio/ menhera]]'' subculture.

* TakeThatAudience: Thanks for her popularity and her sudden rise to the top 3 at the yearly election, her top 3 celebration implies this. The jab was specifically aimed at the playerbase whom only voted for specific, unvoiced idols so that they may receive voice, then have them sink into obscurity once they finally got voiced. Ironically, Riamu still maintains a huge amount of vote after being voiced, staying at relatively high position in the top 20's.

* CoverVersion: ''Ookina Furudokei'' in Cool Jewelries 003.

** When she was first revealed, she was compared by some to [[Anime/PuellaMagiMadokaMagica Homura Akemi]] due to her appearance, shy nature on her unidolized form, and her idolized outfit. However, these comparisons are less common now, and so does the Shiori comparisons.

* BuxomBeautyStandard: Of course she's far from being the largest, but she wears baggy clothing hiding the assets she has. The artwork for her ImageSong brings more attention to them, in case anyone did not notice them before, as she's using her bust to hold down pages of a music book.
* ImageSong: ''Bright Blue'' and ''Ginga Toshokan''.

* TheNamesake: She was crowned ''Cinderella Girl'' for 2021.

* ThereIsNoKillLikeOverkill: All but one of Fumika's cards in the original Cinderella Girls feature debuffing as their special ability. However her ''S Rare+'' has ReadingsAreOffTheScale potential: there's a chance it will reduce an opposing idol's stat to [[CurbStompBattle zero]]. The main thing from keeping this card from being a GameBreaker, is the stat it reduces is entirely random.

* ThinksLikeARomanceNovel: For the Producer. She becomes more and more interested in love stories after he wins her heart. The idea of using a HotLibrarian ploy has crossed her mind, but she's way too timid to ever attempt it.
* UnkemptBeauty: If it wasn't for the Producer she'd never try to pretty herself. Normally doesn't bother to wear makeup or comb her hair.

* AttentionDeficitOohShiny: Her interview in the ''Master Collection'' DramaCD takes place during a baseball game. She constantly forgets/ignores Staff-san during the performance, occasionally making unidol-like comments against the opposing team and cheering whenever her team pushes forward.
* BaseballEpisode: She's the baseball themed idol.
* BuxomBeautyStandard: Played with and Subverted. Her bust size isn't really that striking compared to other top-heavy idols, but it's very well pronounced in her cards.

* CoverVersion: ''Perseus'' in Passion Jewelries 003.

* ImageSong: ''Kimochi ii yo ne - Itoushou!'' and ''Dear My Dreamers''.
* KindheartedCatLover: Her favorite in-universe baseball team is the ''Miyazaki Cats''.
* ModestyShorts: Illustration on ''S Rare+'' card.

* EroticEating: How she eats a pomegranate in front a mirror on her ''S Rare'' card illustration.

* ImageSong: ''Hotel Moonside'' and ''If''.

* LovableSexManiac: Though she doesn't specifically speak about sex, her constant innuendo with kissing is an allusion for it. Has mild degrees of AnythingThatMoves, as she relentlessly hits on Staff-san during her DramaCD. However [[spoiler:the ending to the same skit reveals she might have never been kissed before, let alone been in a sexual relationship.]]

* SacredFirstKiss: It's alluded at the end of her ''Master Collection'' DramaCD skit, [[spoiler:that Kanade has never actually kissed a guy before.]]

* SpitTrailKiss: With the pomegranate.

* YoungerThanTheyLook: Her mature looks make people confuse her with an office lady. She's still in High School.

* CoverVersion: ''Ningen tte Ii na'' in Passion Jewelries 003.
* EarlyBirdCameo: Appeared in the PV for Onegai Cinderella alongside Momoka Sakurai (who were both unvoiced at the time of the PV's release), but didn't receive her CD until the seventh batch of releases.
** She finally gets some screentime in episode 16.

* GoofySuit: Her animal costumes are designed to look cute and adorable.

She is also one of the original members of the titular unit of the manga Manga/TheIdolmasterCinderellaGirlsU149.

* AdorablyPrecociousChild: Acts like she's a serious, logical adult, and yet she is still 12 years old. Probably the reason why she is a ButtMonkey.

* AtrociousAlias: She has a habit of adding english words in front of her family name such as Cool Tachibana or Wild Tachibana. because she somehow finds it cool.

** [[spoiler:In chapter 4 of Starlight Stage's Near to You event commu, because Arisu is glad to become friends with Momoka, Arisu tells Momoka to call her by her first name.]]

* FriendlyRivalry: With Momoka Sakurai in Starlight Stage. This is obviously evident in the ''Near to You'' event commu, where in the prologue Arisu and Momoka smack-talk on who's becoming a better leader for the event (which Sanae took the role eventually). In Chapter 1 of the event commu, Sanae brought the duo into competitive lessons. Compared to Momoka, according to Sanae, Arisu is kind of big-headed, but she is good when she understands the theory behind things (as in being logical). [[spoiler:Chapter 4 of the commu brings further friendship of these two, in which Arisu finally asks Momoka to call her by her first name because Arisu is happy that they've become friends. Hey, they even have a toast to celebrate their friendship!]]
* GamerChick: Likes games that offer intellectual challenge, such as puzzles and strategy. Not just limited to consoles or handhelds either. While devoted to them, she's nowhere near as addicted or hardcore as Anzu or Sana.
* ImageSong: ''in fact'' and ''to you for me''

* TheTeam: She's the sixth member of the original Little Marching Band Girls (LMBG) unit. She plays a recorder. She is also one of the original members of the titular unit of the manga Manga/TheIdolmasterCinderellaGirlsU149.
** In Starlight Stage, she's instead part of the ''Einherjar'' unit, along with Minami Nitta, Fumika Sagisawa, Aiko Takamori, and Yumi Aiba.
* WhoNamesTheirKidDude: She definitely feels this way about her name, especially since using non-native names for Japanese girls is not considered socially normal.
* {{Workaholic}}: Tends to deeply research and study assigned tasks. Her interest in mystery novels makes her overanalyse things. ''[=U149=]'' reveals she focuses on her studies due to fearing her parents (who are workaholics themselves) would disapprove of her wanting to become an idol and not love her anymore.
* WolverinePublicity: Downplayed as a whole series perpective. But Arisu is often featured when it comes to the younger idol groups and is one of the main lead characters in the ''[=U149=]'' manga and anime.

* BigBreastPride: In the upper tier for bust size, which is further enhanced because she's rather short. She wears outfits emphasizing her cleavage and flaunts how she's "dangerous" in a swimsuit during a {{Yonkoma}}.

** Later appears in episode 15, scolding Kaede along with Mizuki.
* CareerVersusMan: Quit being a cop and became an idol, largely because the Producer convinced her.

* CoverVersion: ''Kibun Soukai'' in Passion Jewelries 003.

* HardDrinkingPartyGirl: Drinks her liquor straight out of the bottle.
* ImageSong: ''Can't Stop!'' and ''Odorimakuro☆Dancing Night''

* OlderThanTheyLook: Due to being so short.
* TheTeam: Part of the ''Yoi Otome'' unit in Starlight Stage with Kaede Takagaki, Miyu Mifune, Nana Abe and Shin Sato.
* TheTease: Quite a lot. Plays with the KinkyCuffs sexual fantasy.
* UnexpectedCharacter: While not unpopular, she makes her debut at a time when Yumi Aiba and Takumi Mukai were the top-ranked Passions in the most recent election. Due to her occasional cameos in the anime, she's not as unexpected as some of the other entries on the list.

* CoverVersion: [[Music/ShiinaRingo ''Onna no Ko wa Dare Demo'']] in Cute Jewelries 003.
* DitzyGenius: Shes incredibly intelligent and fairly well-versed in the sciences but she has a short attention span, doesn't clean up after herself, and doesn't even bother trying to groom herself.
* EstablishingCharacterMoment: She ''sniffed'' the producer on street while he's running a film shoot and ''became convinced that he was the perfect specimen for her "experiment"'', she then immediately asked the producer to make her an idol too within ''seconds'' after knowing what the producer does.
* ForScience: Rather than being scouted by Producer, she chose him as part of one of her experiments. She became an idol for this reason.
* GirlishPigtails: Gains two small ones in idol form.

** While usually has [[{{Cloudcuckoolander}} unusual thoughts]], she can be philosophical when she wants to be, which can be seen in Starlight Stage main commu [[https://www.youtube.com/watch?v=92ZjRGoXEOU episode 33]].

* ImageSong: ''Himitsu no Toilette'' and ''PROUST EFFECT''

* MadScientist: She embodies this trope.

* PervertedSniffing: She pulled this on Producer and his smell convinced her that he was the right one for the experiment.

* TheNoseKnows: Shiki's defining quirk. She is fixated on sniffing things. Her sense of smell might be more sensitive than normal.
** On the in-universe radioshow ''Magic Hour'' SP 11, Shiki mentioned that the remaining aroma in the studio already filled her with happiness before the show even begins. When questioned why did she think so, Shiki only said that the identity of the host and guest of last week's show is a hint.[[spoiler: ''Magic Hour'' SP 10 was hosted by Aiba Yumi and the guest was Aiko Takamori, they are both flower loving idols and used flower scented products liberally through out the show.]] So Shiki picked up the remaining scent after a whole week, that's quite a keen nose.

* UnkemptBeauty: For example, her hair is a bit messy.

* AnimalMotifs: Thanks to one of her SR+ foxes. More specifically a [[AsianFoxSpirit Kitsune]]

* CoverVersion: ''Reset'', the credits song of ''VideoGame/{{Okami}}'' in Cool Jewelries 003.

* PandaingToTheAudience: Her ''S Rare'' panda suit.

* DoesNotLikeShoes: Does not wear shoes in the ''Spin Off!'' short, which is only noticeable toward the end, but a heel is shown next to her foot at one point while she's driving. Doubles also as ObscuredSpecialEffects, as her feet are completely hidden, conveniently off camera or covered by her dress until she puts the van she's driving into reverse.

* WolverinePublicity: Downplayed as a whole series perpective. But Arisu is often featured when it comes to the younger idol groups and is one of main lead characters in the ''[=U149=]'' manga and anime.

* HiddenDepths: She has a slight identity crisis in ''[=U149=]'' over her maturity compared to other kids, causing her to have a silent panic attack and need a break when she's about to bungee-jump for a show. She admitted she was terrified after completing the jump, even though she fell with [[BeYourself the grace the director didn't want from her]].

* AtrociousAlias: She has a habit of adding english word in front of her family name such as Cool Tachibana or Wild Tachibana. because she somehow finds it cool.
* BerserkButton: While usually calm, constantly mocking or treating her like a kid can get her worked up. In Manga/TheIdolmasterCinderellaGirlsU149, it takes some time before she opens up to her producer due to him unknowingly doing just that.

** She hesitantly allows this for the younger idols in ''[=U149=]''. When Haru asks though, she flatly refuses.

* {{Workaholic}}: Tends to deeply research and study assigned tasks. Her interest in mystery novels makes her overanalyse things.
* WolverinePublicity: Downplayed as a whole series perpective. But Arisu is often featured when it's come to younger idols group and is one of main lead character in U149 Manga.

* SurprisinglyGoodForeignLanguage: Her English is very smooth and accurate compared to her colleagues. Makes sense since she used to live and study in America before quitting university and return to Japan.

%%* CuteLittleFangs

* WomanChild: During a commu with Momoka, Riamu behaves like a clingy infant towards her in the grounds that Momoka really embodies a motherly figure and wants Momoka to spoil her like a baby despite their age difference, which Momoka reluctantly agrees. She also attempted this on Karen during the "Yume No Nozoitara" event commu, except this time Karen is smart enough to reject her advances.

* OlderThanTheyLook: Due to her old fashion music style and idol costumes.

* YoungerThanTheyLook: Strangely enough, her singing voice of ''Onna no Michi wa Hoshi no Michi'' make her sounds like an older Enka singer.

* AgeInsecurity: The main reason she attemptsto make herself look young are rooted in the insecurities she has regarding her age and occupation. Her and Nana, another idol with a similar dilemma, even have an event together focusing on their struggles with being an idol at their respective ages.

* GirlishPigtails: Two of them.

* TakeThatAudience: Thanks for her popularity and her sudden rise to the top 3 at the yearly election, her top 3 celebration implies this. The jab was specifically aimed at the playerbase whom only voted for specific, unvoiced idols so that they may receive voice, then have them sink into obscurity once they finally got voiced.

* HatesBeingAlone: Her commu in Starlight Stage explains that she mostly alone in her home because her parents [[ParentalNeglect business]] and most people only approached her when she wearing her animal costume.

* IJustWantToBeSpecial: She tries to stand up to Shiki (who hed found her lost hood) in ''[=U149=]'' because she believes without it, she's no good to her parents. The Producer helps her see that even without it, she always cheers up the people around her.

* AtrociousAlias: She has a habit of adding english word in front of her family name such as Cool Tachibana or Wild Tachibana. because she somehow find it's cool.
* BerserkButton: While usually calm, constantly mock or treat her like a kid can get her worked up. In Manga/TheIdolmasterCinderellaGirlsU149, it's take sometime before she open up to producer due to him unknowingly treat her like a kid in the beginning.

* CharacterDevelopment: Her "Arisu Story" card have her embraced her name as she finally convinced that her parents give her this name because of their love for her.

* StrawberryShorthand: She loves strawberries so much. One of her cards in Mobage is named "''Strawberry'' Challenge/Smile". You can see the strawberry imagery as a background on her CD cover.

* AdorablyPrecociousChild: Acts (and speaks) like a proper mature lady. She insists on being treated as a lady... but uses the very childish [[JapaneseHonorifics honorific]] ''-chama'' when addressing the Producer.

* TheOjou: She's a ProperLady type, wealthy, has butlers, drinks tea etc. She's from a wealthy upbringing, not unlike Iori in the 765PRO games. As her interview proves, she's relatively out of touch with how common folks live, but is open to trying out new things. Becoming Ojou-chama is kinda hard for Momoka, sacrificing her time to enjoy her "childish" life as the other kids do for things like tea time and stuff (though she had it again, seen in Hi-Fi Days commu, sort of). On ''Magic Hour'' SP 17, she said when she grows up as an actual adult, she wanted to ride a bicycle and go as far as she can.. because her parents won't let her ride a bike for safety reasons.
