Go To

Classi9 note  is a manga by Yoshimura Tsumuji, which was serialized in Gangan Online from April 2015 to April 2017 and compiled into five volumes.

Taki Ren goes to Vienna to study music, but she has to take the identity of Taki Rentarou in order to stay in Melite Music School, as it is an all-boys school. Therefore, she is put in Class S- with other “quirky”, but brilliant composers, among them Wolfgang Amadeus Mozart, the only one to know her secret.

Classi9 contains examples of:

  • A Day in the Limelight: Some members of Class S- get a chapter that delves deeper into their history or character and usually explains why they are in Class S-, if it wasn’t already obvious:
    • Chapter 4 reveals Tchaikovsky’s weakness kink and his systematical test of strength. It also introduces his habit of shutting people up by feeding them nuts and his work on ballets as he was making researches for the Nutcracker.
    • Chapter 5 focuses on Beethoven and how he dealt with losing his hearing, leading to a Duet Bonding and Ren’s first hug.
    • Chapter 7 explains why Chopin is nicknamed the Poet of the Piano and reinforces his status as ill boy.
    • Chapter 9 focuses on Haydn’s pranks and motivations and gives us part of his backstory as a choir boy.
    • Chapter 11 shows the full extent of Bach’s Team Dad habits and give us his back story.
  • Adaptation Dye-Job: Beethoven, Wagner and Liszt are the worst offender. Mozart is minor examples, as he used to be a strawberry blond or redhead.
  • Adaptation Personality Change: The worst offender is Beethoven, who went from being a grumpy old man to a soft and occasionally cheerful teenager. Tchaikovsky has also changed a lot, becoming a charming if not sometimes slightly disturbing, bisexual young man.
  • Adaptational Attractiveness: If in-universe, every composer is really attractive and has fangirls partly because of his appearance, it was not the case in real life.
  • Adaptational Curves: Taki Ren was based on the real life, male Japanese composer Taki Rentarou. Having female curves was not one of his attributes.
  • Adaptational Sexuality: In real life, Pyotr Ilyich Tchaikovsky’s homosexuality is a known fact. Some expert even made it one of his reasons behind his semi-permanent depressive disorder, and his brother, who was also gay, discussed it in his biography. In the manga, he is bisexual, or possibly pansexual, as he doesn’t care about someone’s gender so long as they are weak enough to be attractive to him.
  • Affectionate Nickname: Haydn decided to call Ren Takkie, and Mozart stuck with Ren-dear.
  • Age Lift: An interesting example, especially if considering the respective timelines of the real-life musicians. Haydn, who was born before all the other composers except for Bach, ended up being the youngest member of the cast. The rest is at least 16, but no older than 18, which makes Wagner roughly the same age as Liszt even though he married his daughter in real life. (In real life, Wagner was only two years younger than Liszt...) Beethoven is about as old as Mozart, even though in real life he was young enough to be his pupil. Bach remains the oldest and most responsible member of the cast, though.
  • Anachronism Stew: The manga puts composers who have been living in different time periods, some living in completely different centuries, in the same class.
  • Attractive Bent-Gender: Whether she goes as a Ren or Rentarou, the protagonist is really cute; Salieri was smitten by her at school even before the festival, and Liszt and Chopin compliment her when she goes with Mozart to a dinner party as a girl.
  • Berserk Button: Several. Mozart’s is being treated like a smart monkey instead of a human being, along with imitating Beethoven. Bach's is talking shit about his loved ones in front of him (which lead him to blind rage and beating the crap out of bullies, putting him in Class S-). Salieri’s is disrespecting music. Disrespecting Beethoven also bothers Wagner a whole lot, and Class S- as a whole is ready to swing if you speak ill of Ren.
  • Bishie Sparkle: Mozart has his moments.
  • Bokukko: Ren uses male pronouns in public in the Japanese version. She also starts referring to herself as “Rentarou, [her father’s] son” in her narrative.
  • Brick Joke: In chapter 5, Beethoven tells Ren his suicide notes are diary entries more than anything else. He even tells Wagner in an omake with the same plot that titling them diary entries would kill the mood. In chapter 21, the cast uses the length of his suicide notes as a measure for how upset he is.
  • Bunny-Ears Lawyer: Class S- was built on the concept. The 9 students each have their “thing”, be it an unusual fetish or a fragile health, but are still brilliant composers and musicians.
  • Call-Back: During chapter 12, after Bach finishes dealing with Ren’s secret, there are several call backs to previous chapter that almost gave him a heart attack: Haydn calling Ren out and reminding her he’s seen her butt and that she could lose some weight, Liszt and Chopin reminiscing that one time Demon!Liszt pinned Ren to the piano, Ren saying Wagner is chummy with her because of a secret they share…
  • Cannot Spit It Out: Bach has trouble dealing with the gender reveal, and still hasn't managed to tell Ren he knows about her.
  • Career-Ending Injury: The two guys who were hitting on Ren and Beethoven threatened to break Salieri’s finger if he meddled.
  • The Casanova: Mozart is successful with the ladies to say the least. The director mentions he snuck girls in the dorms multiple times, visited brothels, and owns some questionable items. He was even sued by 15 women for getting them pregnant and not taking care of them, although it was proven the children weren’t his.
  • Cast Full of Pretty Boys: And they’re all brilliant musicians too. Mozart lampshades it in chapter 2.
  • Casual Danger Dialogue: Tchaikovsky casually comments on a furious Wagner’s “boring” behavior after kicking him down so Beethoven could douse him in alcohol. Wagner kicked him in the face and he was only upset that Beethoven was easily forgiven. He also gave advice to Brahms on how to insult someone while Wagner was grabbing him by the collar and shaking him because he had insulted him.
  • Catchphrase: Wagner’s automatic response to anything is “I refuse!”, so much Tchaikovsky and Mozart always picture him saying it and Demon!Liszt quotes these words to get Tchaiko off his back.
  • The Charmer: Mozart can be one.
  • Chick Magnet: Mazart is the most prominent one, but every musician has his own fangirls.
  • Child Prodigy: Except for Ren, the main cast qualifies: Haydn is 12 and on the same level as 8 other students several years older than him, all of them music prodigies, Wagner started composing operas after seeing Beethoven perform when they were 5 and 6 years old… Mozart gets a special mention, as he is known as the "Wonderkind" (kinder means child in German). The main reason why he doesn't want to participate in the festival, and also why he had given so few public concerts lately is his struggle with the whole "I want this prodigy to play for me" part.
  • Childhood Friends: Liszt and Chopin have known each other and played together for a very long time. See Heterosexual Life-Partners below.
  • Chivalrous Pervert: Mozart and Tchaikovsky, especially regarding Ren. Tchaikovsky’s main kink relies on the concept, as he is attracted to weak people and loves to dote on them. Mozart is definitely interested in romancing women and even more, but will also fight for Ren’s integrity against his classmates because of rather unlikely and very sexual scenarios he thought might happen to her.
  • Cloudcuckoolander: Beethoven’s love of sweets gives him rather unexpected reactions.
  • Color-Coded Characters: In colored promotional images, each member of Class S- is associated with a color: Ren is magenta red, Mozart is yellow, Tchaikovsky is orange, Haydn is light green, Liszt is pastel blue, Chopin is dark blue, Bach is teal blue, Wagner is burgundy red and Beethoven is violet.
  • Comically Missing the Point: The boys often misunderstand Ren’s charms and customs because they aren’t used to Japanese culture:
    • Wagner automatically expected something akin to seppuku when Ren told him about a traditional ritual for secrets when it was only a pinky swear.
    • When Ren talked about writing the character for “person” on her and then eating it up to fight the stress, Chopin literally bit his hand multiple times.
      • Ren herself apparently didn’t pick up on why Tchaikovsky would be biting her fingers and was more disturbed by the fact that he wasn’t pretending to eat her hand.
  • Covert Pervert: Mozart accuses Bach of being one because he still hasn’t told Ren he knows about her gender.
  • Cut Short: The manga was cancelled earlier than expected, which explains the rushed ending.
  • Deaf Composer: Beethoven lost his hearing when he was a kid according to Wagner and Mozart, and he is always welcoming help to know how what he is composing sounds.
  • Daddy's Girl: Ren’s narrative is dedicated to her father and she often refers to herself as her father’s daughter or son. She still writes him letters even though she can’t post them. She also says Bach is a great guy as he is very similar to her father, something Mozart interpreted as a father complex for a moment.
  • Dances and Balls: The composers are frequently invited to balls and dinner parties, and the final arc focuses on the Melite Music School Festival, that ends with a dance party.
  • Dark and Troubled Past: Class S- suspects Bach of having one.
  • Defrosting Ice King: Wagner never mixed with his classmates before Ren arrived, only considering Beethoven worthy of his attention. He became significantly more sociable under Ren’s influence, something Liszt picked on in the later chapters.
  • Depraved Bisexual: Played with. Tchaikovsky is into some kinky stuff and if Mozart is to be believed, being an object of his affection isn't a good thing. He also seems to prefer weak men over women, and having his heart broken by his girlfriend back in Russia did not help his slightly sadistic tendencies. He is apparently renown around Vienna for being extremely dangerous when provoked, his second name being the “Poisonous Mushroom of Russia”. However, he is a perfectly chivalrous and nice guy during his interactions with most of the cast.
  • Disappeared Dad: It is implied Ren hasn’t seen her father in a very long time, even before moving to Vienna. Turns out Mr. Taki died years ago of tuberculosis and that by going to Melite, Ren is carrying his legacy and fulfilling his last wishes.
  • Dissonant Serenity: Tchaikovsky doesn’t discard his smile when he blatantly threatens people by his mere presence, or when he brutally silences Wagner.
  • Drinking Contest: This is apparently a recurring occurrence in Class S-, Mozart tries to outdrink Tchaiko, but it never works. Haydn also wants to compete against Tchaikovsky when he is old enough.
  • Dude Looks Like a Lady: While wandering in the city with Ren, Beethoven was mistaken for a crossdressing girl by a couple of guys who traveled to Vienna just to pick up chicks. Since they wouldn't let it go, even after Salieri attested for Rentarou and Ludwig’s alleged gender, Beethoven outright stripped to prove he was a man. Liszt also counts, as Ren remarks he looks like a woman when she meets him and is bewildered when they compare the size of their hands.
  • Duet Bonding: Ren is subject to this trope several times: when she plays her assignment with Mozart at the dinner party, when she helps Beethoven with his symphony and ends up falling out the window with him, leading to her first western hug, when Chopin and Liszt help her with her fluidity and technique in piano playing, and when she has to compose a piece with Bach for the festival.
    • The festival has several duet bonding moments, as Haydn and Chopin spend a lot of time together to make sure he can play the ridiculous amount of notes Haydn had written, and Tchaikovsky gets to interact with Demon!Liszt long enough to hit on him, something that had never happened before. Just like regular!Liszt, Demon!Liszt rejects Tchaiko, but they're quite friendly and playful after the duet. Salieri also hoped to use the festival to get closer to Ren, but ended up working with Mozart instead.
  • Elaborate University High: Melite music school is huge, with dorms, music classes and rehearsals rooms everywhere. Wagner has a theatre to rehearse ’’his operas’’ inside the school.
  • Elegant Classical Musician:Implied by the manga's premise.
  • Establishing Character Moment: Mozart is introduced drinking wine and fooling around with girls in a tavern, until he sees the Beethoven impersonator and proceeds to musically destroy him to defend his friend. The first time Wagner appears, he refuses to mix in with the others and has a rather nasty expression on his face.
  • Exact Words: Wagner told Ren to bring someone she liked to the opera with her, expecting her to take Beethoven. It was a great plan, getting rid of tickets he didn’t want, letting Beethoven appreciate on of the last forms of entertainment he still has and helping Ren out on her homework on music drama. After finding out Wagner had received these tickets from his father and feeling bad for taking them, Beethoven and Ren managed to get a third ticket with Tchaikovsky and Liszt’s help and Ren gave one to Wagner, arguing he was someone she liked.
    Wagner: “Didn’t you hear what I said?! I gave those tickets to you…”
    Ren: “[…] You told me to “go with someone you like!” and as per your instructions, I came here to invite you, Wagner!”
  • Fandom: As Ren found out in chapter 2, everyone in Class S- has his own fanclub. The fangirls will often try to deliver gifts and fan letters for their favorite musicians, and if they are very lucky, he might be there to receive their affection directly.
    • Beethoven’s devoted fandom includes musicians as well. Brahms travels all the way to Vienna to meet composers with second names and gives him a stack of fan letters. Wagner’s big secret is that Beethoven is the only musician he admires, and if he wouldn’t say it himself he is at least as big of a fan as Ren.
  • Fanservice: Chapter 12 gives us rather gratuitous shots of Bach in the shower. Tchaikovsky and Liszt’s performance for the music festival is also an In-Universe example, especially for the Liszt fangirls.
  • Foreshadowing: In chapter 3, when Mozart gets drunk and starts cuddling Ren, threatening to expose her secret, she says she wouldn’t mind being exposed to Tchaikovsky and Bach as they look like they can keep a secret. By the end of the manga, they are the only ones other than Mozart to know about Ren’s gender, and become her Secret Keepers.
  • Gender Flip: In real life, Taki Rentarou was a male composer who died of tuberculosis. Ren’s father, who was also a musician, died of tuberculosis after his daughter’s birth and has more similarities with the original Taki Rentarou than Ren.
  • Girls Love Chocolate: As per tradition, the boys comment on the fact that Beethoven never had anyone to share his love of sweets with until Ren came in and qualified their interest as girly.
  • The Glasses Gotta Go: Tchaikovsky didn’t wear his glasses during his festival performance with Liszt.
  • Goodbye, Cruel World!: Subverted. Both Ren and Wagner came across at least one of Beethoven's suicide notes and freaked out, but Mozart reveals Beethoven's never serious about them. He picked up the habit during his Sense Loss Sadness period, contemplating suicide more often than not. Now they help him clear his head, and are more like journal entries than actual suicide notes.
  • Goroawase Number: The 9 ("kyu") in the title fits nicely into the word as pronounced in Japanese ("kurashikku").
  • Hair-Trigger Temper: Wagner has a very short temper, especially when Tchaiko’s pushing his buttons. He is almost always annoyed and gets angry for the smallest things, such as realizing inviting Bach to the opera would look weird because they’re too tall together.
  • Harem Genre: Ren’s harem is smaller than you’d expect considering the number of male characters, as only Mozart, Tchaikovsky, Salieri and Bach are shown to have possible feelings for her. Mozart also has his own harem of fangirls.
  • Heterosexual Life-Partners: Chopin and Liszt are roommates, go everywhere together, invite each other as their +1 to dinner parties, play together, etc. Not to mention Chopin is usually the one to keep Demon!Liszt under control and Liszt became a full time nurse over the course of his friendship with Chopin.
  • Hot-Blooded: Wagner, see Hair-Trigger Temper above.
  • I Can't Dance: Ren invokes this trope when Mozart invites her as his +1 at a dinner party. She gets better, but still dances the female part as both Mozart and Bach forgot to correct her.
  • Idiosyncratic Episode Naming: Each chapter is a Mouvement.
  • In-Series Nickname: Haydn calls Ren Takkie and most of the cast calls Tchaikovsky Tchaiko.
    • Except for Tchaikovsky and Ren, everyone in Class S- has a second name linked with their musical talent and style, see Red Baron below.
  • In Vino Veritas: Narrowly averted when Mozart got wasted trying to beat Tchaiko in a drinking contest and started clinging to Ren as he would with a girl. Tchaiko, Haydn and Liszt remarked he usually didn't get that close to men, even when drunk. Luckily Mozart sobered up before another slip up.
  • Innocently Insensitive: Haydn doesn't mean to be rude when he criticizes Ren's accent or Chopin's stamina, he's just a child after all.
  • Irony: In chapter 6 Salieri defends his absence of girlfriends by saying he had made an oath to God never to lay a finger on a woman for the sake of music… While grabbing Ren’s shoulders.
    Ren: “Right now you’re breaking that oath with ten fingers!!!”

    • In an omake replaying chapter 5 with Wagner finding one of Beethoven’s suicide notes instead of Ren, the note consists of “In short: I wanna die.” When Wagner finds Beethoven asleep in a pool of ink, his first reflex is to shake him and call his name, forgetting Beethoven can’t hear him or read his lips. The Master Musician’s only response is “I dunno why but the world is shaking like mad… Gonna die. I’m gonna die”, while looking inconvenienced by this turn of event.
    • In chapter 2, Mozart makes a comment about Ren being surrounded by good-looking men and Liszt remarks it’s not that big of a deal since Rentarou isn’t a girl.
    • Tchaiko’s saying he isn’t a sadist and explaining how he is, in fact, a more passive type of sadist. To sum it up:
    Tchaikovsky: “People who are weak and pitiful are irresistibly precious to me, but I would never want to personally restrain anyone. If possible, I’d just gaze upon them as they struggle.”

Mozart doesn’t buy it.

  • Intelligible Unintelligible: It is unclear if Schumann’s speech is just too low for most people to understand or if he actually is silent, but somehow his classmates, Chopin and Liszt have perfectly normal conversations with him.
  • Jerkass: Wagner absolutely refuses to mix with his classmates and even acknowledge their talent except for Beethoven, whichdoesn’t mean he will be nice to him. He gets better, but it takes some time.
  • Keet: Haydn is an overly excitable 12 years old prankster who can’t stay still, even on stage.
  • Ladykiller in Love: The boys remarked Mozart stopped his womanizing tendencies with his developing friendship with Ren.
  • Last-Name Basis: Except for Ren with Mozart, Tchaiko, Haydn and Beethoven, Class S- is generally on last name basis. Liszt justifies it to Schumann:
    Liszt: “You have been wondering why we call each other by our surnames? […] It’s confusing to call each other by our first names in school, that’s why.”
  • Let's Duet: Rather common in the manga, but Liszt and Chopin take the cake. They're almost like a couple when it comes to duets, coming to dinner parties together just for that. Chopin remarks his stage fright gets considerably better when Liszt is playing with him. This leads to friendly bickering on their styles.
  • Like an Old Married Couple: Liszt and Chopin’s relationship. See Heterosexual Life-Partners and Let's Duet above.
  • Living Legend: Mozart and Beethoven are two of the most renown musicians of their time.
  • Locked Out of the Loop: Anyone who doesn’t know about Ren’s gender by the end of the manga.
  • Long-Haired Pretty Boy: Liszt, despite thinking he isn't that good looking. Ren often forgets he is, in fact, a boy and commented several times that foreigners were something else because of him. Beethoven's hair is quite long too.
  • Manic Pixie Dream Girl: Lampshaded by Chopin in the last chapter: Class S- became much closer and happier after Ren’s arrival, from Wagner participating in class business to Haydn having someone to play with.
  • Meaningful Rename: The director accepts to let Ren study in Melite if she passes as a boy because he heard "Rentarou" was a boy's name in Japan, as adding -tarou makes a name masculine. It is revealed in the last chapter the director accepted to bend the rules for Ren and to give her that name because her father and the director were friends and fellow students or professors in Melite before Ren was born. Mr. Taki had told the director he was having a child and would either name them Ren or Rentarou.
  • Music Stories: The manga takes place in an elite music school and Duet Bonding happens several times.
  • Nervous Wreck: Chopin’s stage fright makes him this before the music competition. Ren is very nervous too, afraid to bring the team down because her music isn’t good enough, so Mozart enlists their classmates to play her piece instead of the regular musicians.
  • Never Gets Drunk: Tchaikovsky is a type 3, as alcohol was one of the rare things keeping him warm in Russia he can drink vodka like one would drink water. Ren and Haydn cannot get drunk either, but only because they’re not old enough to drink yet.
  • The Nicknamer: Mozart calls Rentarou Ren-dear or Ren-chan even in class, and Bach gets all the “dad”/”papa”/”daddy” nicknames. It’s unknown if he came up with Tchaiko or if Haydn did, as he is also prone to give people nicknames.
  • No-Sell: Mozart’s charms and Tchaikovsky’s innuendos have little to no effect on Ren.
  • Not What It Looks Like: A meta and in-universe example, for different reasons. In chapter 7, Ren asks Liszt for help to practice her piano and his demonic persona comes out. Ren tries to escape as soon as she sees it, but Liszt grabs her by the collar and restrains her, saying she wouldn’t be leaving the room that night. This is followed by some pretty suggestive imagery. In-universe, Chopin walks in to Liszt pinning Ren to the piano and moving her arms like a doll. He did say he’d be pounding his mindset about the piano into her body. Chopin’s first thought was that Demon!Liszt had somehow caught Ren to force her to play in his demonic state.
    • Beethoven’s nap on his ink-covered desk in chapter 5 also counts.
  • Oblivious to Love: Ren never saw any of her classmates as love interests due to her position. She never thinks about "liking" one of the boys romantically, but musically. She also never picked on Salieri's crush on her, despite how obvious it is. Beethoven is a milder, more platonic example. He is unaware of Wagner's admiration for him, and is always pleasantly surprised to see he has fans.
  • Older Than They Look: Haydn thought Ren was 12 when she walked in. Considering she is a baby-faced, 15 years olds Japanese girl crossdressing as a boy and thus very short, it makes sense.
  • One-Gender School: Melite. It’s the reason why Ren has to pass as a boy.
  • One-Steve Limit: When Schumann asks Liszt why they are all on last name basis in Class S-, Liszt reminds him there are two Franz in the class, Haydn and himself.
  • Performance Anxiety: Chopin’s got a bad case of stage fright, to the point that he has already passed out while on stage, something his weak constitution doesn’t help. Truth in Television as the real Chopin held around thirty concerts in his life and preferred small and cozy venues to big crowds when performing.
  • Perpetual Frowner: Wagner seems to be always angry. Chopin apparently told Liszt his face was so scary it gave him a stomach ache.
  • Perpetual Smiler: Tchaikovsky’s default expression is a pleasant smile, that can become quite threatening if he wants it to. He lampshades it in chapter 11 when Wagner accuses him of laughing about his fight with Mozart.
    Tchaikovsky: “I wasn’t laughing. This is just how I look.”

    • Stepford Smiler:Implied. He had his heart so badly broken by his ex-girlfriend back in Russia he wonders if Ren can make him feel things again.
  • Protectorate: A musical example. Talking badly of Ren's music is the class’s common Berserk Button. Beethoven and his work also qualify, as Mozart, Ren and Wagner were all ready to defend his honor and name against that impersonator.
  • Red Baron: Except for Tchaikovsky and Ren, every member of Class S- has a “second name”, related to their impact on music. If Tchaikovsky isn’t famous enough to have one yet, he is still known as the “poisonous Mushroom Of Russia” around Vienna.
  • Rescue Hug: A strictly platonic version. When Beethoven falls out the window in chapter 5, Ren jumps right after him. He ends up on top of her and cradling her head to protect her. He hugs her properly afterwards to show his gratitude, but Wagner walks in on them.
    • Funnily enough, the same thing happened with Wagner in an omake, with Tchaikovsky walking in on the hug.
  • The Rock Star: … Of classical music. Mozart is one with his Casanova tendencies, his abuse of wine, his attitude and of course, his talent.
  • Running Gag: Tchaikovsky commenting on his classmates’ occasional helplessness as alluring.
    • Mozart commenting on Bach’s Team Dad attitude and giving him all sorts of dad-themed nicknames, only to act just like him when it comes to Tchaikovsky or Ren’s integrity.
    • Schumann’s silence meaning something to his classmates and the Chopin-Liszt duo.
    • Tchaikovsky’s habit of shutting people up by putting a walnut in their mouth as a reference to the Nutcracker.
  • Scholarship Student: Bach came from a poor background and luckily didn’t lose his scholarship for Melite after going bonkers when bullies insulted his family and he broke their arms
  • Secret-Keeper: Mozart met Ren before she knew Melite was an all-boys school, he even led her there. Later on, Tchaikovsky and Bach learn about Ren’s gender too, and are such good secret keepers they never told Ren they knew. Ren is also Wagner’s secret keeper, as they agreed she wouldn’t reveal his admiration for Beethoven if he took part in the music contest.
  • Secret Secret-Keeper: Bach and Tchaikovsky, for different reasons, never told Ren they knew about her secret.
  • She Cleans Up Nicely: Ren looks absolutely gorgeous at the dinner party, for which she dressed as a girl, and is also very well dressed and attractive at the school's festival dance party.
  • Ship Tease: Since Ren is Oblivious to Love but endearing and inspiring, the manga easily offers a fair share of ship tease between part of the cast and her:
    • Mozart and Ren are roommates and he is the only one to know about her secret, at least officially. He is very protective of her integrity and quite cuddly with her, and it is clear she cares about him a lot.
    • Tchaikovsky showed he was attracted to Ren pretty early on, and despite Mozart’s warnings she seemed fine with hanging out around Tchaiko. It went as far as Tchaikovsky asking Ren out on a date, Ren saying yes and Tchaiko saying she might have healed his broken heart.
    • Bach, after the inverted Unsettling Gender-Reveal, started having feelings for Ren or maybe just acknowledging them.
    • Salieri: Salieri is the only character explicitly Sweet on Polly Oliver, and once again Ren has been nothing but encouraging and sweet to him.
  • Shout-Out: One of the guests at the dinner party in chapter 13 is a Madame Bovary. She faints upon witnessing Liszt and Chopin’s performance.
  • Sick Episode: Ren catches a cold in chapter 18 and the whole class takes care of her.
  • Silent Bob: Schumann almost never speaks, and when he does it’s a mumble too low for anyone to understand.
  • Slumber Party: The storm in chapter 15 sent Liszt and Chopin out of their room to look for a place to crash in because they were too scared. Beethoven caught a glimpse of Liszt’s hair and thought there was a ghost in his room, so he ran to Mozart and Ren’s dorm. Bach heard some noise and came to check on them, then Liszt and Chopin ran in, followed by Tchaikovsky and Haydn. Tchaikovsky brought alcohol with him and turned the impromptu get-together into a slumber party, so Ren fetched Wagner so he could join them.
  • Smells Sexy: Mozart is very fond of Ren's "oriental fragrance" and tried to hug her and smell her hair as much as possible in the first chapters.
  • The Smurfette Principle: Ren is the only female character to have appeared multiple times in the manga, and she has to cross-dress. Justified as Melite is an all-boys school.
  • Split Personality: Liszt is a very nice and friendly person, until he starts playing. The moment he touches the piano, his demonic persona takes over, and according to Chopin he might even hurt himself. Regular!Liszt doesn't remember much of his performances, but Demon!Liszt knows everything Regular!Liszt does.
  • Stepford Smiler: Mozart is a downplayed example: for all his happy and charming demeanor, he is clearly unhappy with the implications of being the Wunderkind, which explains his absence from the public stage.
  • Strange Minds Think Alike: When Liszt revealed Wagner laughed when he got drunk, Mozart, Ren and Bach’s immediate reaction was to classify this piece of information as highly disturbing. Tchaivovsky and Beethoven were up in a second to force him to drink without having to come up with a plan together because they knew exactly what to do.
  • Sweet on Polly Oliver: Salieri vowed to never touch a woman for the sake of music, but ends up falling for Ren without knowing she is a girl.
  • Sweet Polly Oliver: Ren has to pass as a boy to stay in Melite as it is an all-boys school, and the director threatened to expel her and Mozart if anyone else was to find out.
  • Sweet Tooth: Beethoven and Ren bond over their love of sweets. Beethoven is in the Genius Sweet Tooth category, and was shown to be quite adamant and pushy when it came to pudding.
  • Team Dad: Bach is Haydn's roommate and takes on the responsibility of making sure he is presentable. He also lends Ren his notes, watches out for Chopin and Liszt, cleans Beethoven's room, makes sure Tchaikovsky and Mozart don't mess up too much... Mozart lampshades it by systematically calling him dad-themed nicknames.
  • Teen Genius: Most of the cast qualifies.
  • Troll: Mozart regularly trolls Salieri, but that time he tricked him into wearing a dress for their performance during the school festival wins.
  • Tsundere: Beethoven is the only musician Wagner respects, but there is no way in hell he will be nicer to him than to his other classmates. His way of expressing his admiration of the Master Musician when around him is about as far from heart eyes as you can be. He even refuses to acknowledge he is a fan of Beethoven.
    Ren: “Wagner, could it be… That you are also a fan of Beethoven’s?”
    Wagner: “I’m not his- his fand or anything!!!”
  • Unsettling Gender-Reveal: Inverted. Bach was never attracted to Ren romantically before finding out about her gender, but it did disturb him a lot. However, after that, he started having some sort of romantic attraction to her.
  • Unusually Uninteresting Sight: Mozart and Beethoven take the latter’s suicide notes as this. Mozart knows it’s no big deal because Beethoven is stronger than he looks strength and wouldn’t take his own life, and Beethoven sees them as diary entries more than suicide notes.
  • Vodka Drunkenski: Subverted with Tchaikovsky. He can sure drink a lot, and is as eager to get others drunk if his drinking contests with the others is anything to go by, but vodka has little to no effect on him and therefore, he was never seen drunk.
  • Weakness Turns Him On: Played straight with Tchaikovsky. Be it male or female, once he finds someone endearing because they are weaker than him or helpless, he will be attracted to them.
  • White Hair, Black Heart: Played With with Liszt. While he is a generally nice and friendly person, once he touches the piano, his demonic persona awakens. Everyone sees him as some sort of evil when he is entranced, and Demon!Liszt gets along very well with Tchaikovsky, who is far from being an angel himself.
  • You Wouldn't Hit A Guy With Glasses: Subverted: Tchaikovsky states Wagner fought him and then smashed his glasses.
