* CannotSpitItOut: She spends most of the series trying her hardest to deny she has feelings for Kousei and refusing to admit her crush on him even after she notices it. [[spoiler:She kinda confesses to Kousei near the end of the series, but he feels too confused to give her an answer. Then Kaori dies, so it will clearly take some time until Kousei can sort out things with Tsubaki.]]

* HopelessSuitor: Unfortunately for Tsubaki, even with Kaori out of the picture, it's very unlikely that Kousei will ever think of her as more than a sister figure.

* AlwaysSomeoneBetter: Emi and Takeshi feel this way towards Kousei - the two always did well in competitions when they were little yet were always beaten by Kousei, making them even more determined to surpass him in the future.

* ManicPixieDreamGirl: As Kousei explains, she's the one who filled his world world with colours. Then it's played for drama very quickly. It's revealed that this was planned by Kaori because as it turns out, [[spoiler: just like Takeshi, Nagi, and Emi, Kaori was also moved by Kousei's music and it brought colours into her world and when Kousei stopped playing music, she dropped piano and picked up the violin just to try and help him get back on his feet.]]

* AbusiveMom: Not only was she strict when it came to Kousei learning new pieces on the piano, but she would also hit him or forbid him from going to bed whenever he made mistakes. The reasons behind this are later revealed: [[spoiler:she really loved him, but her illness made her push him too hard. She was scared at the prospect of leaving him alone in the world with no source of income, so she pushed him harder and harder in order to be sure that he would be able to earn a good living as a musician. When Seto calls her out on her overly harsh treatment of her son, Saki reveals that she is deeply panicked because she feels she's running out of time to teach him all she feels she must in order to secure his future. Later flashbacks prior to her illness (and at the beginning of it) showed that she was gentle and loving most of the time, and in the end, her final thoughts are of Kousei.]]

* TroubledAbuser: She may have emotionally and physically abused her son, leaving him severe emotional scars, but it's eventually revealed she had issues of her own. [[spoiler:Her illness was what made her into an abuser.]]

* LoveAtFirstNote: Ever since she heard Kousei's first performance when she was a child, she has loved and deeply admired him.

* ClingyJealousGirl: The reason she's hostile towards Kousei at first was because she's jealous that he stole her brother's attention away from her.

* TemptingFate: ''Twice''. [[spoiler:First, in his childhood when he wished that his mother just dead already: his mother dead shortly few days after that. Second, when he rejects the similarity between his late mother and Kaori: they become more and more relevant as the show goes on, which finally become true with Kaori's death.]]

* BigSisterInstinct: Claims to be a big sister figure to Kousei as she always checks up on him and his health. [[spoiler: It is later revealed that she does love Kousei in a romantic manner, but is oblivious to her own feelings.]]

* ClingyJealousGirl: She really doesn't like it when Kousei and Kaori are getting along. She also isn't happy about Kousei teaching piano to a cute little girl like Nagi.

* GreenEyedEpiphany: Tsubaki doesn't begin to realize her feelings for Kousei until she starts to become jealous of Kousei hanging out with Kaori, [[spoiler:and until Kousei tells her about his plans to enroll in a music-oriented school, which may cause him to move far away.]]

* HopelessSuitor: Unfortunately for Tsubaki, [[spoiler: even with Kaori out of the picture]], it's very unlikely that Kousei will ever think of her as more than a sister figure.

* {{Tsundere}}: She can be very quick-tempered and violent and she has great trouble with being honest with her feelings for Kousei.

* AloofDarkHairedGirl: She has black hair, is very pretty and also mostly composed, at least compared to Takeshi.

* StalkerWithACrush: A non-romantic version. The OVA revealed that when he was a child, he used to follow Kousei home from school and would listen to him practice piano.

A former child prodigy in playing piano. He lost the ability to play the piano after his mother died of illness when he was 11, leaving him with a trauma that prevents him from hearing the sound of his own playing. He lives in a "colorless world" until Kaori shows up and makes him play piano again.

* AlwaysSomeoneBetter: Emi and Takeshi feel this way towards Kousei - the two always did well in competitions when they were little yet were always beaten by Kousei, making them even more determined to surpass him.

* TheDreaded: As Kaori explains to Tsubaki and Watari, Kousei Arima's name is infamous in the music world due to his perfectly straight down to the notes piano playing always granted him the winner place easily, but also become boring in the process for younger and casual audience that seek something different from the music itself.

* BigSisterInstinct: Claims to be a big sister figure to Kousei as she always checks up on him and his health.

* AccidentalPervert: When Kousei first sees Kaori playing music with a bunch of children, his first instinct is to take a picture... but the wind made Kaori's skirt blow up, so he accidentally takes a picture of her panties.

* AlwaysSomeoneBetter: Emi and Takeshi feel this way towards Kousei - the two always did well in competitions when little yet were always beaten by Kousei, making them more determined to surpass him.
* BlitheSpirit: Without even realizing it, Kousei's piano playing inspires many people - Emi and Takeshi are inspired to take up piano because of how he played at the age of five. [[spoiler: And Kaori was inspired to switch to violin mjust so she'd be able to accompany him one day.]] When he begins to play again, he continues to be inspiring to other musicians.
* BrokenPedestal: Takeshi greatly admired the "Human Metronome" Kousei because of the way he followed the score to perfection, thinking of him as a "hero". He becomes disappointed when he finds out Kousei is suffering from emotional and psychological issues that prevent him from playing the piano to perfection, since this makes him just another "human". Emi [[spoiler:and Kaori]] on the other hand, already admired him from before he became the "Human Metronome", so they like him better when he plays the way he wants.

* ImaginaryLoveTriangle: Kousei falls for Kaori despite being told Watari and Kaori like each other and that he doesn't have a chance with her. Watari however does want Kousei and Kaori to end up together since Kaori seems to enjoy investing a lot of her time into Kousei and his piano-playing. [[spoiler:Confirmed that, yes, she actually does have feelings for him]].

* ObliviousToLove: He completely misses the hints that Tsubaki doesn't think of him as a brother anymore, that Kaori may not be only interested in Watari, and that Watari had been trying to hook Kaori and Kousei up for the entire story. [[spoiler: It's only when Kaori tells him of her and Tsubaki's love for him, does he actually know of this.]]

** His glasses give a scary shine effect in episode 17 when he initially refuses Watari's invitation to [[spoiler:visit Kaori together]] because he doesn't know what he should say to her, or how he should act when he sees her after [[spoiler:she starts to losing hope in life]].

* BoyishShortHair: She has short hair, which emphasises her tomboyish personality.

* EveryoneCanSeeIt: It appears that everyone, besides Kousei and Tsubaki herself, already knows she loves Kousei as more than a brother.

* GreenEyedEpiphany: Tsubaki doesn't begin to realize her feelings for Kousei until she starts to become jealous of Kousei hanging out with Kaori.

* PatientChildhoodLoveInterest: Tsubaki has liked Kousei since childhood, but their relationship has always been sibling-like. She's fine with it until Kousei begins to become closer to Kaori.

* UnknownRival: To Kousei when they were kids. Surpassing Kousei is her sole motivation to take part in piano competitions, yet Kousei never noticed her and doesn't recognise her at the reunion.

* ChildProdigy: Used to be one thanks to his mother. He got the nickname "Human Metronome" because of how accurately he played from the music score no matter how difficult it was, despite being a mere child.

* DidNotGetTheGirl: He anticipates this ever since he's told from Day 1 that Kaori is interested in Watari. [[spoiler:Kaori does return his feelings and, in fact, had been in love with him since she was five; but Kousei only finds this out after Kaori dies via a letter given to him from her parents. He still has Tsubaki by his side, but it's unclear if he will ever reciprocate her feelings.]]

* LikeParentLikeSpouse: Kaori and his mother are quite similar; they're both obsessed with music, they're constantly pushing him into becoming a better pianist and are prone to drastic mood swings. They are both also sick with unnamed diseases and [[spoiler:as of chapter 44, they also pass away untimely.]] This is lampshaded in episode 15 when Kousei, Watari and Tsubaki visit Kaori in the hospital and Kaori yells at him for not practicing for the upcoming competition in such a way that in Kousei's eyes, the room begins to glitch and Kaori turns into his mother.

* ObliviousToLove: He completely misses the hints that Tsubaki doesn't think of him as a brother anymore, that Kaori may not be only interested in Watari, ''and'' that Watari had been trying to hook Kaori and Kousei up for the entire story. [[spoiler: It's only when Kaori tells him of her and Tsubaki's love for him, does he actually know of this.]]

** Kousei's glasses shine in an intimidating matter after he decides to go into serious playing mode while he's accompanying Nagi in a four-finger piano duet in episode 18.

* WellDoneSonGuy: Even despite the abuse he got from her, Kousei's motivation for doing well at piano competitions as a child was to please his mother and make her feel better.

* {{Determinator}}: Kaori is very determined to be able to do the duet performance with Kousei once again after [[spoiler:she's hospitalized due to her growing serious illness, to the point she starts doing walking therapy and take the high risk surgery, which is sadly fails and claim her life.]]
* DisappearsIntoLight: [[spoiler:Her fate after finishing the long-awaited duet with Kousei in final episode. It's unclear whether the Kaori that's playing alongside Kousei is indeed her spirit before going to afterlife or just Kousei pure imagery, but it makes him realize that her surgery is fail and she's dead for sure.]]

* GratuitousEnglish: She loves throwing in random heavilly-accented English words into her conversations.

* ManicPixieDreamGirl: As Kousei explains, she's the one who introduces colours back into his life. Then it's played for drama very quickly. It's revealed that this was invoked by Kaori because it turns out, [[spoiler: just like Takeshi, Nagi, and Emi, Kaori was also moved by Kousei's music and it brought colours into her world and when Kousei stopped playing music, she dropped piano and picked up the violin just to try and help him get back on his feet.]]
* MasterOfTheMixedMessage: She keeps giving hints of being interested in Kousei to then make it look like she has a crush on Watari. [[spoiler:If anything, there are various hints throughout the story that she's had something for Kousei since before the story began, and that Watari has been trying to hook the two of them up for the entire story while hinting how Kaori actually feels, albeit very vaguely in a kind of "don't give up hope" way. At the end of the series, she confesses to Kousei in her letter that she was never interested in Watari, Kousei was the one she loved all along, but she had pretend to have a crush on Watari for Tsubaki's sake.]]

* NotSoDifferent: With Tsubaki. [[spoiler:It turns out that Kaori also envying her all this time because she knows everything about Kousei's life due to their shared childhood.]]

* ReluctantFanserviceGirl: To her great dismay, Kaori usually ends up in quite embarrassing fanservice situations such as when the winds blow up her skirt and allows Kousei to see her panties and when Kousei and Watari sneak an accidental peek at Kaori receiving a sponge bath when visiting her at the hospital.

* SweetTooth: She likes to eat cakes. [[spoiler:This is part of her "breakthrough" after she realized she don't have much time left in her life. She started to eat anything she wanted and not minding her weight so she wouldn't regret after she was dead.]]
