Character subpage for the second year students.
Voiced by: Yumiri Hanamori
Played by: Mayu Hotta (live-action movie)
A second year student at Shuchi'in and valet of the Shinomiya family, specifically for Kaguya. Her family has served the Shinomiyas for generations and gained their trust. Ai was personally assigned to enter Shuchi'in with Kaguya and support her high school life.
- Adaptation Dye-Job: Her hair is dirty blonde in the live-action movie rather than blonde.
- Adaptational Heroism: She's based on the celestial envoy that took Princess Kaguya away from everybody she knew and loved on Earth. Here, she tries to encourage Kaguya's relationships and wants her to be happy.
- Affectionate Gesture to the Head: Gives one to Fujiwara on chapter 62 after being complimented on her beauty by the latter. She also does this to Erika when they indirectly compliment her in chapter 50 of We Want to Talk About Kaguya.
- Ascended Extra: She has made small appearances as early as chapter 3, but wasn't given a full name, formal introduction, and significant role until chapter 19.
- Be Careful What You Wish For: She comments on multiple occasions that it would be better if Kaguya and Shirogane would just confess their feelings for each other rather than bother with the whole Duel of Seduction. Once they actually do get together, Kaguya's constant bragging about their relationship annoys her far more than all her denials ever did.
- Beleaguered Assistant: While not normally the case, in chapter 42 she's this when Kaguya keeps asking her for help as Ai is trying to bathe.
- Beneath the Mask: Extras states that she has many modes like gal and maid mode, but her real personality is actually similar to Kaguya's and that she gets scared a lot and cries easily. This was shown in chapter 42 when she realizes that she wants to be in love too with the biggest blush on her face. Shown again in chapter 58 when she starts crying out of frustration for failing to seduce Shirogane. The rap battle chapter had Hayasaka (as Hayasaka-kun) rap to Kaguya about how she's frustrated with putting on all of her personas for the latter's sake, and how she wants to find love and act for herself for once, putting all of her previous grievances into the limelight for the first time.
- Best Friend: Of Kaguya, as they're practically family to each other. While Kaguya does have friends, Hayasaka is the only person who knows Kaguya as a whole, warts and all.
- Bitch in Sheep's Clothing: Downplayed as she's not that nasty. She acts like a cheerful teenage girl in front of her friends, referred as "Gal mode", but she's actually a Deadpan Snarker.
- Brief Accent Imitation: When she's showing Shirogane into the Shinomiya estate during the sick episode, she stuffs her bra slightly, wears bright blue color contacts and adds a slight accent to her speech so that she'll look and sound like a foreigner.
- But Not Too Foreign: She's a quarter Irish, implying that unlike the rest of the main cast, the color of her eyes and hair is not cosmetic to fit the manga, as the early chapters point out.
- Childhood Friends: With Kaguya, having known each other since infancy (though they were separated when they were two and didn't see each other again for another five years).
- Compressed Hair: Her Hayasaka-kun persona wears a black wig that is far too small to hide all her normal hair.
- The Confidant: Having known Kaguya since they were children, Hayasaka is one of the few people around whom Kaguya's amiability is genuine.
- Consummate Liar: The narration notes that she lies as easily as she breathes. Given that she has to juggle several alter egos at the same time, this is a very useful skill to have.
- Cool Big Sis: She's the only person in Kaguya's life who resembles family and takes care of her most personal needs. She even admits to viewing Kaguya as a little sister in chapter 75.
- Covert Pervert: The first thing she does upon finding out that Kaguya and Shirogane kissed is asking Kaguya what it was like, despite there having been far more important questions at the time.
- The Cynic: Believes that people cannot be truly loved for who they are. It says a lot about her since she has never shown her real personality around others.
- Deadpan Snarker: Very much so, especially regarding Kaguya's obvious feelings for Shirogane.Hayasaka: "Well, Miss Kaguya, your plans all relied on the assumption that the president would invite you to go with him. And you know what happens when you assume things.
Kaguya: And why exactly are you looking through your boss' notes, Hayasaka?''
- In an official "Snark Test" included in Volume 4, the highest snark level is called "Hayasaka Level".
- Deliberate Under-Performance: It's implied that Hayasaka deliberately keeps herself at exactly 114th place among the test ranking to avoid drawing attention to herself. Given her line of work, it's not like she'd have to get into a good college to ensure stable employment.
- Disguised in Drag: Whenever Fujiwara comes over to the Shinomiya estate, she disguises herself as a butler.
- Doppelgänger: Albeit they are different in height, she can impersonate even Kaguya given the circumstance.
- Dude, She's Like, in a Coma!: Gender inverted. She thinks that Kaguya should've taken advantage of Shirogane's sleep to kiss him.
- For Halloween, I Am Going as Myself: When her class does a cosplay cafe for the culture festival, she just wears her work outfit.
- The Gadfly: Towards Kaguya at times. In one instance, Shirogane is taking a bath while on the phone with Kaguya. Hayasaka helpfully pointed out that Kaguya is speaking with a naked man. Chapter 111 reveals that she gets it from her mother.
- Got Me Doing It: She ends up having a Kaguya-esque Imagine Spot when Kaguya says that she wants to get the same phone model as Shirogane.
- Gyaru Girl: She dresses in kogal fashion while at school.
- Heterosexual Life-Partners: With Kaguya. While their relationship is technically that of a mistress and a servant, Word of God says that they're more like very close sisters. Hayasaka is proverbially Kaguya's right arm... and the logical part of her brain.
- Hypercompetent Sidekick: To Kaguya. Hayasaka is a master multi-tasker, capable of pulling off miracles for the sake of Kaguya, and without all the neuroticism that her dear friend and employer has.
- I Can Explain: Insists this after Kaguya sees her using the Shinomiyas' fancy bath. Fortunately, Kaguya doesn't care about that.
- I Just Want to Be Loved: She mentions at several points that she wants to be able to fall in love just like Kaguya has, though she doesn't have anyone that she's interested in.
- I Just Want to Be Normal: She really wishes she didn't have to juggle around several identities and have a boyfriend of her own. Too bad babysitting Kaguya is a full time job on its own.
- I Want My Beloved to Be Happy: Played with. She's a Shipper on Deck for Shirogane+Kaguya because she witnessed firsthand that Shirogane brought colors back into Kaguya's life when they met, Kaguya being the person who is dearest to her. Ever since then, Hayasaka has done everything in her power, and then some more, for Kaguya to be with Shirogane.
- Informed Attractiveness: She'll often get a comment remarking how hot she is.
- Ivy League for Everyone: Her "Hayasaka-kun" persona is a Harvard graduate to drive home the fact that he's supposed to be a Teen Genius.
- Laser-Guided Karma: After scaring Kaguya with the rape thing, Hayasaka has to scan the sheets with a microscope.
- Legacy of Service: Her family has served the Shinomiya family for generations.
- Like Brother and Sister: Eventually she becomes this to Shirogane after she admits she's actually Kaguya's maid.
- Manipulative Bastard: She knows to anticipate people's thoughts and use to her advantage during her missions. Fujiwara is the only exception.
- Master Actor: Hayasaka is able to juggle multiple alter egos with only minor changes to her appearance in an effort to keep her identity as Kaguya's valet a secret from her classmates. It helps that the people she's trying to fool are neither in her class or in her circle of friends.
- Meido: She wears a maid outfit at home, but her tasks are much more varied then simply taking care of Kaguya.
- Meta Guy: She usually makes observations about Kaguya's situation that most readers would be saying at that point in the manga."The home visit, the fireworks, the birthday, and the moon-viewing. How do you explain all these events and still not make any progress?"
- Motif: She has a subtle stellar motif, with her nails, Line ID, and phone case all having a star pattern. It's symbolic of her devotion to Kaguya, since the moon is almost always accompanied by stars.
- Ms. Fanservice: She's an attractive young woman that wears a maid outfit at home. Chapter 42 has her spend most of the chapter in nothing but a bath towel.
- Ninja Maid: She can- and has needed to- flip over security lasers, maintain multiple alter egos, and find blackmail material.
- Non-Uniform Uniform: Hayasaka removed the collar from her school uniform, and cut the skirt short. She notes that it's "more or less within the loopholes in the regulations" when Kaguya points it out (it still ends up getting her in trouble with the public morals commitee despite this... or rather it would if Miko wasn't such a pushover). It's implied that even though she describes her garb methodically describing femininity as a "weapon", Hayasaka is very much enjoying the perks of youth by wearing it, and was just pandering to Kaguya.
- Not So Different
- For all the grief she gives Kaguya over her inability to just confess to Shirogane, she has her own unhealthy view on romance.If you don't put on an act, you won't be loved.
- She's also nearly as sheltered as Kaguya when it comes to romance, though less ignorant. Her reaction to hearing Kaguya suddenly kissed Shirogane is a blushing meltdown and being told it was a French kiss has her call it lewd and on par with having sex on campus.
- She only acts like her normal true self around her mom, at which point she's exactly like Kaguya when she's squeeing over Shirogane.
- She thinks that to get someone to love you, you have to put on a facade. Shirogane calls her out for hiding behind masks, despite him also doing his best to keep up the image of the perfect student and council president.
- For all the grief she gives Kaguya over her inability to just confess to Shirogane, she has her own unhealthy view on romance.
- Not So Stoic:
- Even as stoic as she is in her default personality, she sheds tears after reading Sweet Today.
- She's considerably embarrassed when Kaguya makes her try to seduce Shirogane... and in turn Hayasaka starts falling for his courtesies. She's so mad that Kaguya has to apologize to her, though this makes her see why Kaguya fell for the guy.
- Even though she goes the extra mile for Kaguya, juggling multiple fake identities and maintaining lifestyles for all of them, it's shown that there's a significant part of her that does those things for the mere fun of it. If it weren't the case, she wouldn't do any of the stuff she does.
- Obfuscating Stupidity: She has thus far always placed at exactly 114th place in all of the end of semester exams. Considering that she got a similar education and lives with the best possible study partner in the school (and already has stable employment that would cancel out the need for her to get into a good college), it's clear that she's doing it on purpose. It's also implied that she's lowering the bar intentionally so that this doesn't become an additional burden for her, as she's busy enough as it is.
- Oh, Crap!: When she witnesses firsthand why Kaguya likes Shirogane so much, she's so bewildered and embarrassed that she admonishes Kaguya for intentionally putting her in a situation that brought her so close to falling for the guy herself.
- Pastimes Prove Personality: Kaguya states she likes to watch videos of things being crushed in a hydraulic press in her free time.
- Phenotype Stereotype: Subverted. She has the stereotypical blonde hair and blue eyes, but she's actually part Irish (which would normally be depicted as a redhead).
- Precision F-Strike: Drops one about Kaguya's father for his horrible parenting.
- Promoted to Love Interest: In the Offical Doujin's Kindergarten A.U., she is Shirogane's primary love interest (Kaguya still has a crush on him, but it's instead a Precocious Crush).
- Real Name as an Alias: All of her alter egos are named Hayasaka, though some of them use it as a first name.
- The Reliable One: Shown to be a very competent maid and valet, such as when she obtains required items for the sister school banquet ahead of time for Kaguya and Shirogane due to rain.
- Sarcasm Failure: She's taken completely off guard when Kaguya finally admits that she's in love with Shirogane and can only utter a Flat "What" before getting embarrassed.
- Sarcastic Devotee: While she does loyally follow Kaguya's orders, she spends a lot of time snarking at her.
- Secret Identity: Hayasaka goes the extra mile to pretend she isn't Kaguya's servant. She has a gyaru persona, a "Hayasaka A. Smithee" persona from another school, and a Teen Genius butler persona to keep up illusions.
- Secret Keeper: She's the only person who knows how antsy Kaguya actually is behind wraps.
- Secret Test of Character: Her meeting with Shirogane at a karaoke bar served for her to determine what is it that Kaguya saw on him. Much to Hayasaka's own embarrassment, there was plenty to like.
- Secretly Wealthy: In terms of personal weath, she is the independently wealthiest character among the teenaged cast with over 40 million yen in savings thanks to having served as Kaguya's maid for a decade (!) .
- Servile Snarker: She is very loyal to Kaguya, but she isn't above making fun of Kaguya's stubbornness. In fact, Kaguya is the only person she snarks at since she often hides her true personality from others.
- Shipper on Deck: She really supports the idea of Kaguya and Shirogane getting together, and often asks Kaguya outright if she likes him.
- Shrinking Violet: Her real personality, according to the volume extras.
- Siblings Wanted: Played with. Hayasaka is very much in the same line of thought when it comes to Kaguya as Kaguya herself does for her; that is, Hayasaka considers Kaguya her family and treats her like her little sister.
- Situational Sexuality: She has always framed her goal as a boyfriend, but plants a kiss on Fujiwara in a moment of desperation. Both are freaked out by it.
- Small Role, Big Impact: In spite of having relatively less exposure in the story than the main characters, Hayasaka's positive influence on Kaguya has led the latter to become closer to Shirogane.
- Smarter Than You Look: Inverted. She actually has the lowest grades among the second-year cast (yes, even below Fujiwara). Though the fact that she's the only one outside of the top ten whose ranking didn't change suggests that she's Obfuscating Stupidity to avoid drawing attention to herself (since she doesn't exactly need to get into a good school when she already has stable employment).
- The Stoic: Always has the same calm expression and demeanor.
- Strong Family Resemblance: She looks like a slightly younger version of her mother.
- Sue Donym: Uses the alias Haysaca A. Smithee in front of Shirogane.
- Sweet Tooth: According to the narrator, Hayasaka finished "most of" a multilayered cake Kaguya bought.
- Turn the Other Cheek: She has a monumental patience for Kaguya's neuroses and whims, which goes to show how much she loves her mistress.
- What the Hell, Hero?:
- When Kaguya intends to give a ride to Shirogane during a typhoon, Hayasaka admonishes her because it would mean that she would have to give her car seat to Shirogane and walk home by herself under heavy rain. Kaguya was just joking about making her walk home in the rain, but too late: Karma has already struck in the form of Shirogane accidentally soaking her.
- Hayasaka berates Kaguya for setting her up with Shirogane on a dare, on which she was dangerously close to succumb to his niceties.
- When You Coming Home, Dad?: Her mother wasn't able to see her often when she was a child and instead left daily messages in a notebook. Chapter 87 reveals that this is still an issue when she doesn't show up at the sports festival.
- Wholesome Crossdresser: She has no problems pretending to be "Hayasaka-kun", a ridiculously talented butler persona who she even made a convoluted backstory for.
- Wrench Wench: Downplayed example. Kaguya reveals that she built her own mini computer and based on the image we saw, she really enjoyed it.
- You Keep Telling Yourself That: In spite of all her moaning and snarkiness, there's little to nothing she wouldn't do for Kaguya.
Two unnamed classmates of Kaguya and Hayasaka.
- Gyaru Girl: Like Hayasaka, they both dress in kogal fashion.
- Locked Out of the Loop: While both of them know that Hayasaka has a job that keeps her from hanging out with them after school, neither of them are aware that she's Kaguya's valet. One of them even complements Hayasaka on her maid "cosplay" during the culture festival.
- No Name Given: Neither of their names have been revealed at this point in the story.
- Those Two Guys: They always appear together, and very little is known about them as individuals other than what their parents' jobs are (one of them has a parent that's an advertising executive, and the other's is the president of a famous IT company).
Voiced by: Momo Asakura
Played by: Natsumi Ikema
A female student in the same year as Kaguya, Shirogane, and Fujiwara. She occasionally interacts with the student council, in which she typically either receives or provides love advice. Is currently going out with Tsubasa.
- Ambiguously Bi: There have been a few points that suggest that she might have actually have a crush on Maki, like the fact that she constantly imitates her, asked to dance with her during the bonfire, and blushed when thinking about how much Kaguya resembles her. She also explicitly tells Hayasaka and Fujiwara that she finds them attractive and wouldn't mind kissing either of them (although it's possible that she just said that to keep them away from the student council room).
- All Women Are Lustful: Most of the time, Kashiwagi is the one that makes advances on Tsubasa.
- Audience Surrogate: Many of her thoughts and reactions resemble those that readers would have in regards to the student council's antics.
- Beta Couple: Kashiwagi and her boyfriend are this. While they have their issues and come to the Student Council for help; they are dating and openly communicate with each other, while Kaguya and Shirogane refused to admit their feelings and are stuck in a constant war to make the other confess.
- Beware the Nice Ones: A member of "The Shuuichin VIPs who do heartless actions without giving them a second thought".
- Birds of a Feather: Even though the two may not acknowledge it, she shares quite a bit in common with Kaguya as far as their intense and possessive tendencies in romance, and the two often seek each other out for advice and counsel.
- Characterization Marches On: In her introductory chapters, it seemed Kashiwagi was going to be fairly similar to her boyfriend, taking everything the Student Council says and does at face value. However, over time she instead becomes the Only Sane Woman and Audience Surrogate, with bits of The Smart Girl and The Gadfly mixed in.
- Childhood Friends: She's been best friends with Maki since kindergarten.
- Clingy Jealous Girl: A more restrained example, but Chapter 97 reveals her to suspect her boyfriend of cheating for the smallest infractions (such as eating with and being tutored by Maki). She even goes as far as hiring a detective to observe his movements.
- The Confidant: Kaguya goes to her for advice when it comes to matters of love. And while she has yet to tell Kaguya herself, she's also the only one outside of Hayasaka who definitely knows that Kaguya and Shirogane are head over heels for each other and is fully supportive of their relationship.
- The Corruptor: By accident. Her getting to first base with Tsubasa in chapter 97 was the first romantic kiss that Kaguya had ever seen, so she ended up replicating it during her First Kiss with Shirogane.
- Did They or Didn't They?: In Chapter 48, Kashiwagi and her boyfriend see the Student Council for some more love advice, and because of their demeanor around each other and how they talk about their vacation together, it sounds like they've gotten more intimate. By the end of the chapter, neither one of them gives a straight answer, even though they both tricked the Council into thinking they were going to be a couple of Makeout Kids when they got alone time in the Student Council room. Chapter 138 answers pretty plainly they did.
- Elegant Classical Musician: She plays the cello, which she initially picked up because Maki was also taking lessons.
- The Gadfly:
- In Chapter 48, she performs several increasingly romantic interactions with her boyfriend while in the student council room to rile up the council members, knowing that they are right outside the room and watching.
- In Chapter 85, she tells her boyfriend that she'll be alone at home that night. When Iino accuses her of wanting to bring her boyfriend home, she turns it around by claiming she just wanted her boyfriend to call her, and suggesting Iino's accusation (and by extension her) was lewd.
- Hair Decorations: She wears a red hairpin on the left side. The Yonkoma bonus chapter reveals that Maki also used to wear one.
- Hypocritical Humor: After discovering Kaguya and Shirogane's Secret Relationship, she comments to herself that they really shouldn't be doing this sort of thing in school. This coming from the girl who was caught making out with her boyfriend in a locker during the culture festival.
- I Have This Friend...: She lampshades the trope when Kaguya uses it.
- Irritation Is the Sincerest Form of Flattery: It's mentioned in the Yonkoma bonus chapter that she has been deliberately imitating Maki ever since they were children due to their friendship. Ironically, the only time it actually bothered Maki was when she unknowingly imitated her by stealing her crush.
- Love Makes You Dumb: Not directly, but her grades did hit a sharp decline once she started dating (dropping from 4th to 27th over the course of two semesters) because she spends most of her precious study time tutoring her boyfriend.
- Manipulative Bitch: Downplayed on the bitch part since she's typically genuinely nice, but she has been shown to manipulate both the Student Council and even her own boyfriend for her own amusement.
- Meaningful Name: Nagisa translates to "beach" or "shore", exactly the sort of name you'd expect from someone whose family runs a shipbuilding company.
- Nice Girl: A kind and polite girl, who is president and founder of the volunteering club, no less.
- Non-Idle Rich: Her family runs a major shipbuilding company and her grandfather is the head of the Japan Business Federation. She's also the president and founder of the school's Volunteering Club, which does charity work.
- Not So Above It All:
- Chapter 97 outs her as an untrusting Clingy Jealous Girl bordering on Yandere, a sharp contrast to her otherwise Only Sane Woman and Straight Man roles from previous chapters.
- She also gets mad at her boyfriend for the most petty of reasons (i.e. she gets upset because he rarely gets upset), showing she has as many innocent and dumb romantic insecurities as the Student Council does.
- Not So Different: To Kaguya. While Kashiwagi is generally the Only Sane Woman to her, chapter 97 reveals they are just as jealous, murderous and even having the exact similar ideas of what minor activities counts as cheating.
- Official Couple: With Tsubasa.
- Only Sane Woman: Occasionally takes this role when juxtaposed with the antics of the student council, and sometimes even her own boyfriend.
- Secret Secret-Keeper: She figures out Kaguya and Shirogane's Secret Relationship almost immediately and tries to help them have some private time. Gets upgraded to a proper Secret Keeper in chapter 167 when Kaguya goes to her for more love advice and admits that they're dating.
- Shadow Archetype: What Maki is to Kaguya, Kashiwagi is to Fujiwara. Friends for a long time and genuinely close, but she ends up dating her best friend's crush without knowing about said crush. And while both are intelligent, Kashiwagi can feign ignorance while Fujiwara is a full blown Genius Ditz.
- Shipper on Deck: Like most of the school, she ships Kaguya/Shirogane. She gets really excited when she discovers that they've had a Relationship Upgrade.
- Sickeningly Sweethearts: How the student council view her and her boyfriend.
- Smug Smiler: Very capable of doing these whenever she successfully Trolls or outsmarts the Student Council members.
- Teen Genius: She is shown to consistently place in the top 10 test scores of her class. Under her tutelage, her boyfriend also managed to remarkably increase his score ranking from 139th to 84th.
- Unknown Rival: She is completely oblivious to the fact that Maki considers her a rival for Tsubasa's affection.
- Yandere: Mostly Played for Laughs. She threatens to kill her boyfriend, Tsubasa and Maki if it turns out they are having an affair, and states they would already be dead if the affair was sexual. And when she finds out that both Tsubasa and Maki are friends with Ishigami, she gives him a Death Glare that horrifies him as she states she wants to be his friend.
Tsubasa Tanuma / Kashiwagi's Boyfriend
Voiced by: Taku Yashiro
Played by: Yūtarō
A male student in the same year as Kaguya, Shirogane, and Fujiwara. He constantly asks Shirogane and the Student council for love advice, but more often than not ends up inadvertently messing with them in some way. Despite this, he has a (mostly) healthy relationship with Kashiwagi. Due to his plain looks and personality (and the fact that they don't quite care about him), the student council members don't learn his name until Chapter 109, so they mostly referred to him as "Kashiwagi's Boyfriend".
- Adaptation Dye-Job: Literally. In the manga, he dyes his hair grey after summer break, but in the anime it's dyed brown.
- Chick Magnet: He has a stable relationship with Kashiwagi and Maki is head over heels for him as well. It's later played for laughs because, as it turns out, Kashiwagi and Maki like each other more than they like him.
- Connected All Along: Turns out the doctor who examined Kaguya in chapter 79, Shozo Tanuma is his grandfather. Also, one of the four Ramen Emperors may be his great-grandfather (or possibly great-great-grandfather given the family's habit of having children at a young age).
- A Day in the Limelight: Chapter 6 of We Want to Talk About Kaguya is told from his perspective, and tells the events directly leading up to his introduction in the main series. Given the fact that it's set before he and Kashiwagi started dating, the narration simply refers to him as "the boy".
- The Ditz: A bit air-headed and unwise in his actions and words.
- Everyone Calls Him "Barkeep": He's almost exclusively referred to as "Kashiwagi's Boyfriend", even after his Given Name Reveal. The anime profiles are the only exception, as they refer to him as "Male Student".
- Foil: Generally, Tsubasa is the result of a person who while insecure about his feelings for the person he likes, ultimately doesn't care about how foolish he looks when showing his affection and throws away his pride to do so. This is very much unlike all of our protagonists, who initially cling to their pride and refuse to really say how they feel.
- The Generic Guy: This was his primary characteristic early on. He had average grades, average looks, little to no personality to speak of, and wasn't even referred to by name until 103 chapters after his introduction (the student council literally just referred to him as "Kashiwagi's Boyfriend"). Although he did start getting better grades thanks to his girfriend's tutoring, and he started dyeing his hair after summer break.
- Given Name Reveal: It took 103 chapters from his introduction before his name was revealed. Before that, he was just referred to as "Kashiwagi's boyfriend". This is lampshaded by Shirogane, Ishigami, and the narration. And his last name was only confirmed via a tweet by the author almost 4 years after his introduction.
- Hidden Depths: He's interested in medicine, and hopes to become the kind of doctor that saves lives in the future.
- Innocently Insensitive: Constantly does things that inadvertently piss off the Student Council and even Kashiwagi.
- It Runs in the Family: Chapter 147 reveals that his grandfather and father both got a girl pregnant when they were Tsubasa's age and he and Kashiwagi have an active sex life... so...
- Love Makes You Dumb: Inverted due to dating Kashiwagi, she regularly tutors him and his grades jumped up from 139th position to 34th by two semesters.
- Love Triangle: Maki threw him at Kashiwagi in the hopes that she rejected him to keep him for herself, but he was so forceful and determined that she didn't. This left Maki outside, looking in.
- A Man Is Always Eager: Subverted, most of the time it's Kashiwagi that makes advances on him and he's been apprehensive about being intimate in more public places like the school festival or a park. The times when he does try to forward their relationship has been mostly chaste like asking the student council why he made her mad or trying to hold her hand. Considering his family history, he might be consciously trying to defy this trope.
- Mistaken for Cheating: Subverted. He was not cheating on Kashiwagi with Maki, though Maki was trying to break them up so she could have him for herself.
- Nice Guy: Despite frequently ticking off the Student Council, he is still this ultimately. Kashiwagi and Maki claim this as one of his positive attributes.
- Satellite Love Interest:
- There's a reason he's constantly referred to as "Kashiwagi's Boyfriend". Nearly every appearance he makes centers around her in some fashion. Even when he went to the Student Council, alone, he ends up talking more about Kashiwagi than he does himself.
- This is made more apparent during the School Festival, where Kashiwagi tells Maki that she likes her more than she likes him.
- Super Gullible: The guy instantly believes anything Shirogane says, no matter how it's ridiculous it is.
Voiced by: Kana Ichinose
Kashiwagi's best friend who has a crush on her boyfriend.
- 13 Is Unlucky: As befitting her role as the resident Butt-Monkey, she's on the cover of volume 13.
- Alone Among the Couples: In the wrap up for the culture festival, she finds herself surrounded by various couples dancing around the bonfire.Maki: I hope you all catch on fire.
- Ascended Extra: Appears as early as Chapter 6 alongside Kashiwagi and Tsubasa, but only appears sporadically in backgrounds and omakes until she finally receives a proper role and character introduction in Chapter 98!
- Big Sister Bully: To her twin brother Mikado, who she likes to roughhouse with for the pettiest of grievances.
- The Blind Leading the Blind: In Chapter 144, Shirogane comes to her for love advice. She points out that she is probably the worst person he could ask, since she is very unlucky in terms of love and she is usually the one who comes to Shirogane or Ishigami for advice. However, since Shirogane would like her opinion on Ice Kaguya's behavior, and because of their similarities, Maki can actually perfectly empathize with Kaguya.
- Butt-Monkey: An even bigger one than Ishigami ever was, considering the fact that even her own friends' attempts to cheer her up or help her cause her to suffer.
- Brainy Brunette: She's a brown-haired girl who is considered to be Kaguya's intellectual equal, scoring only a single point less than her on exams.
- Cerebus Retcon: Her mutual distaste with Kaguya when it's revealed it was caused by their families mutual bad blood between each other. Maki originally wanted to become friends with Kaguya when they first met before Maki's father told her to stay away from Kaguya.
- Childhood Friends: She's been best friends with Kashiwagi since kindergarten.
- Conflicting Loyalty: Between her crush on Tsubasa, and her friendship with Kashiwagi. She seems to be leaning towards the former though, albeit on the School Festival, Kashiwagi gets a hold of her heart once again, prioritizing her over Tsubasa.
- Connected All Along: It turns out Maki is also a descendant of the Shinomiya bloodline, and thus a distant relative of Kaguya (specifically, her second cousin twice removed.)
- Cute Little Fangs: Shows these during many of her surprised or indignant reactions, to highlight her slightly childish and naive nature despite her intellect.
- Deliberate Injury Gambit: Discussed. After seeing Ishigami have to wait on Miko hand and foot when he accidetally broke her arm, she seriously considers getting Tsubasa to do the same to her so he'll spend time with her.
- Elegant Classical Musician: She used to take cello lessons, though it's unknown if she still plays.
- First-Name Basis: One of the biggest differences between her and Kaguya is that she almost always adresses people she's close to by their given names, something that Kaguya never does.
- Girls Are Really Scared of Horror Movies: Like her relative Kaguya, she can't handle spooky stuff.
- Green-Eyed Monster: Downplayed. Maki is extremely jealous of Kashiwagi for dating Tsubasa, but she always tries to put their friendship before her envy. Appropriately, the manga volume where she appears on the cover is green.
- Hair Decorations: Back when she wore her hair down, she had a hair clip identical to the one that Kashiwagi now wears.
- Heroic BSoD: She has a major one at the start of chapter 98 when she has to lie about her feelings for Tsubasa after hearing that Kashiwagi was jealous. She even faints on the road till Shirogane and Ishigami find her by accident while they were hanging out.
- Hoist by Her Own Petard: All of her heartache and sadness over being stuck between her crush and her best friend's love life could have been avoided if she was more honest with the both of them from the start and didn't deflect.
- Hopeless Suitor: It has been noted that she doesn't really have any chance getting together with Tsubasa due to how far his relationship with Kashiwagi has developed.
- In-Series Nickname: Ishigami calls her "Tsundere-sempai".
- Insistent Terminology: Proudly declares herself a member of the Shinomiya family and looks down on others as commoners, despite being in a very distant branch from the main line and not even sharing the same last name.
- Irony: Chapter 129 reveals that she is incredibly artistic, able to make a massive balloon sculpture of a whale and other sea creatures by herself. Despite this, Art is the only class that she doesn't get an A in.
- It Runs in the Family: Being distantly related to Kaguya, Maki is also very intelligent, scoring only a point below Kaguya in exams. She also switches between displaying arrogance and cuteness just as easily (with the exact same facial expressions, no less) and is sensitive to strong stimuli like loud noises. When Shirogane comes to her for advice, she is able to understand Kaguya's point of view and sympathizes with it immediately. She figures out who Shirogane was talking about just from how alike she and Kaguya are.
- Lovable Alpha Bitch: She constantly looks down upon people around her like Shirogane and Ishigami, referring to them as imbeciles and "commoners", though she opens up her true feelings to them quite easily.
- Love Hurts: A Running Gag is that she is always following Kashiwagi and her boyfriend while crying.
- Made Myself Sad: She has a bad habit of making herself depressed when she talks about her lack of luck when it comes to romance.
- Mood-Swinger: She constantly switches between being smug, depressed and acting hot and cold towards others just like her aunt Kaguya.
- One Steve Limit: Averted. Another Maki appears as a jock's girlfriend in chapter 26.
- Open Mouth, Insert Foot: Maki tends to rub off wrongly on people that she meets because she cannot help but express herself contentiously, as if looking for a fight. Kashiwagi knows that her intentions are always more pure than what she shows, but she's not shy in telling Maki to just be sincere and not seek quarrel all the time.
- No Name Given: Played With. Technically, her name appears as early as Chapter 31 (in the exam results). However, we are not told it is her name, and the fact can only be inferred. She finally introduces herself by name properly in Chapter 98.
- Not So Different:
- While she doesn't get along with Kaguya, they're incredibly similar. They are both very proud of being Shinomiyas, very intelligent and very tsundere. Maki seems to be fully aware of this, as when Shirogane wants her advice regarding Kaguya, Maki can empathize so well, that she realizes that the girl Shirogane describes must be Kaguya because they might as well be related to each other.
- Just like Ishigami, she likes hearing about the failing of other people's love lives (because it means that she's not the one that's suffering).
- Post-Stress Overeating: Karen takes her to a cake shop after Erika's disastrous attempts to cheer her up, and she's shown angrily stuffing her face.
- The Rival:
- Being only a point below Kaguya herself, she's her academic rival off screen and they are fully aware of each other. Makes even more sense when it is revealed they are actually distant relatives.
- She thinks herself one for Kashiwagi when it comes for Tsubasa, but cannot bring herself to actually act upon it because she cares about Kashiwagi too much to do anything. As it turns out, Kashiwagi tells her that she likes her more than she likes Tsubasa.
- Secret Keeper: Being Kaguya's cousin, she's one of the few students in the school who knows about Hayasaka's job.
- Secret Secret-Keeper: She already knew about Kaguya's crush on Shirogane as early as autumn of their freshmen year (when Kaguya first fell in love), though she doesn't bring it up until after Kaguya and Shirogane have already started dating.
- Sempai/Kohai: She becomes a borderline Cool Big Sis for Ishigami by the time of the Culture Festival arc, much like his relationship with Kaguya.
- Sensory Overload: Maki has trouble dealing with loud noises, a trait that she shares with her cousin Kaguya.
- Shadow Archetype: She's basically what Kaguya would be if Shirogane was dating Fujiwara, right down to the same birthday, reactions, facial expressions, and lines of thought. Even her hair and eye colors are a more muted version of Kaguya's (brown and pink instead of black and red). Fittingly enough, this is partly why the two don't like each other.
- Sheltered Aristocrat: She is rather innocent when it comes to things like sexuality, thinking that a first time means a kiss. Though she doesn't take it to the same extreme as Kaguya.
- Shipper on Deck: She is shown encouraging Ishigami to confess to Tsubame during the Culture Festival arc.
- Significant Birth Date: As befitting her role as Kaguya's Shadow Archetype, the two of them were both born on January 1st.
- Spot of Tea: She really likes her tea, demanding some the first time she shows up at the student council room.
- Springtime for Hitler: She gave Tsubasa the idea of getting a lame heart necklace as an anniversary present in the hopes that it would make the two of them break up. Kashiwagi loved it so much that she started making out with him in the middle of the hallway.
- Stalker with a Crush: Towards Tsubasa. She's usually following them whenever the two have some free time.
- Strong Family Resemblance: Shirogane and Ishigami notice that Maki and Kaguya share a great deal of mannerisms and attitudes as a result of being brought up in the same way.
- Sudden Name Change: Her last name was listed as Ichijo in the original release for chapter 31. It was changed to Shijo in the tankobon.
- Teen Genius: She's ranked third in terms of test scores among the second year students, scoring only a single point less than Kaguya. She also gets straight A's in everything but Art.
- Third Wheel:
- As a friend of Kashiwagi, she's constantly hanging out with her and her boyfriend as the hanger-on despite her crush on the latter.
- To her horror, she accidentally sees Kaguya and Shirogane sharing an intimate moment.
- Throw the Dog a Bone: Chapter 98 allows her to finally vent about her crush.
- Too Much Alike: Part of the reason she and Kaguya can't get along very well. They are both too similar. Even when she wants to thank Kaguya for spending time with her, she makes it seem like she just wants to insult and show off her skills to her "auntie".
- Tsundere: Even more than Kaguya, natch. Ishigami even calls her "Tsundere-sempai".
- Unlucky Extra: She can often be seen in the background looking shocked (usually in scenes involving Kashiwagi and her boyfriend being intimate).
- By Chapter 98, she finally gains a speaking role and name introduction, becoming an Ascended Extra.
- Vitriolic Best Buds: Gradually becomes this with Shirogane and particularly Ishigami.
- What Does She See in Him?: Ishigami is baffled by her attraction to Tsubasa. Not so much for his looks, but rather the fact that he's an idiotic Extreme Doormat.
- Why Can't I Hate You?: Maki is very upset that her friend, Kashiwagi, got together with the boy she was interested in first. However, she points out that Kashiwagi is the one person she just can't hate, because Kashiwagi views Maki as the person she loves the most.
- With Friends Like These...: Claims to view Kashiwagi as a precious friend, yet openly states her contempt for her for "stealing" the boy she has a crush on. Turns out, Kashiwagi cares more about her than she does about said boyfriend.
A classmate and friend of Shirogane. One of the few known impures attending Shuchi'in.
- All There in the Manual: Pretty much everything known about him comes from the volume 10 extras.
- Kid Detective: He's the assistant of the famous detective named Hajime Echizen and the two have apparantly solved many cases together, including the disappearance of his older brother.
- Hero of Another Story: He is an impure who entered Shuchi'in in order to find information about his missing older brother. He's also the assistant to a famous detective and helped solve multiple cases. This is only ever mentioned in the volume 10 extras.
- Scholarship Student: He's the only known impure in the cast other than the Shirogane siblings, though this is only mentioned in his character profile.
- Those Two Guys: He's rarely seen without Saburo.
A classmate and friend of Shirogane.
- All There in the Manual: Pretty much everything known about him comes from the volume 10 extras.
- Eyes Always Shut: He aparantly only opens his eyes when he shows his true power.
- One Steve Limit: Averted. One of the four Ramen Emperors is also named Saburo.
- Reformed Bully: He tried to sabatoge Shirogane's grades in the past, but now he competes with him fairly.
- Those Two Guys: He's rarely seen without Go.
Voiced by: Madoka Asahina
A member of the mass media club and one of the main characters of We Want to Talk About Kaguya. She is a massive Kaguya/Shirogane shipper.
- Alliterative Name: Karen Kino.
- Ambiguously Christian: Certain dialogue suggests that she might be a Japanese Christian, such as comparing Kaguya to Jesus, attributing various Ship Tease moments between Kaguya and Shirogane as being Good Fortune from God, and outright quoting the Gospel of Luke when she sees their First Kiss.
- Ascended Extra: She's a Recurring Extra who ended up getting her own Spin-Off.
- Audience Surrogate: She's essentially the embodiment of the entire Kaguya x Shirogane shipping fandom incarnate. Her reaction after luckily spotting Kaguya and Shirogane kissing on the rooftop during the Festival arc is almost exactly how the fans reacted out of universe to the same event.
- Berserk Button:
- To her, shipping Shirogane with anyone other than Kaguya is a sin in itself. Funny enough, she's fine with the idea of Shirogane being a harem king so long as Kaguya is his alpha girl.Karen (after Erika proposes that Fujiwara is better suited for Shirogane than Kaguya): That's blasphemy Erika...The President is Kaguya-sama's super darling! The only man capable of winning Kaguya-sama's pure, dignified heart is the President!
- Do not badmouth Shirogane or insinuate that he's involved in shady dealings. She'll pull a (fake) knife on you.
- To her, shipping Shirogane with anyone other than Kaguya is a sin in itself. Funny enough, she's fine with the idea of Shirogane being a harem king so long as Kaguya is his alpha girl.
- Blood from the Mouth: A comedic example. After she catches a glimpse of Kaguya and Shirogane kissing, she passes out and starts to bleed out of her mouth as she's nearly killed from sheer joy.
- Childhood Friends: With Erika.
- Curtains Match the Windows: Karen has brown eyes and hair.
- A Day in the Limelight: Chapter 116 focuses on her and Erika as they interview several students about the upcoming culture festival, and doubles as a Poorly Disguised Pilot for We Want to Talk About Kaguya.
- Early-Bird Cameo: She's the very first character shown in the very first chapter of the manga, but her name isn't given until Chapter 116.
- Fangirl: She's a Kaguya fangirl, though not to the same extent as Erika. She's also a Shirogane fangirl, including having a crush on him.
- Friendship Denial: Ishigami is not her friend, he's her editor.
- Girls Are Really Scared of Horror Movies: Zigzagged. She doesn't have any problem with horror movies and will happily munch down on popcorn during a movie marathon to help build up Erika's resistance, but she is terrified of haunted houses.
- Given Name Reveal: She was the very first character introduced in the series, but she didn't have her name revealed until chapter 116.
- Gone Horribly Wrong: Not only was she the one responsible for having Kashiwagi ask Tsubasa if he had a girlfriend, she was the one who suggested that Tsubasa go to Shirogane for love advice. All this while trying to hook him up with Maki.
- Good Fortune from God: Played for Laughs. She claims that things such as seeing Kaguya and Shirogane riding on a bike together or sharing an umbrella are a gift from the heavens.Karen: There is a God. He preaches the President x Kaguya-sama gospel...
- Hidden Depths:
- She's rather knowledgeable about insects (having read an encyclopedia on them in her father's study) and was able to correctly identify a species of cockroach on sight when it was a good distance away.
- Due to her family owning a publishing company, she can identify different types of paper just by feeling them.
- Love Is Like Religion: Taken rather literally. She is such a rabid Kaguya/Shirogane shipper that she routinely compares their assumed love for each other to an act of God, even claiming that the idea of one of them going out with somebody else to be blasphemy. She goes so far as to directly quote the bible whenever she sees them engaged in a particularly romantic activity like holding hands during the fireworks festival or their First Kiss.
- Ms. Imagination: Her imagination tends to go wild when it comes to Shirogane and Kaguya. Erika even calls her delusional thanks to this.
- Named After Somebody Famous: She's named after Ki no Tsurayuki, a Heian era poet.
- Oh, Crap!: Her reaction when she sees Erika "comforting" Maki about Nagisa and Tsubasa's relationship upgrade.Karen: What on God's green earth is that girl doing?! She doesn't know a thing about love!
- Right for the Wrong Reasons: She is 100% correct about Kaguya and Shirogane being hopelessly in love with each other, though her reasoning is rooted in fangirlish delusions rather than any real observations of reality.
- Sequential Artist: She draws Shirogane/Kaguya doujinshi.
- Shipper on Deck: She ships Shirogane/Kaguya and Maki/Tsubasa.
- The Straight Man: Often finds herself playing this role for Erika.
- Super Strength: She was somehow strong enough to stab a spoon hard enough to stick on a table.

- Those Two Guys: She's rarely seen apart from Erika.
Voiced by: Ayaka Asai
A member of the mass media club and one of the main characters of We Want to Talk About Kaguya. She is a massive Kaguya fangirl.
- Ambiguously Gay: Erika has admitted to having a crush on Kaguya, but she denies having any romantic or sexual feelings for her (claiming that it's more of a platonic idolization). It's never specified if she's telling the truth or if she's just in the closet. Also, the one time she shows interest in getting a boyfriend its because she wants Kaguya to come to her for relationship advice.
- Ascended Extra: She's a Recurring Extra who ended up getting her own Spin-Off.
- Childhood Friends: With Karen.
- Composite Character: She embodies the portion of the student body that fawns over Kaguya.
- Covert Pervert: When Maki mentions that she's already had her first time (thinking that they were talking about kissing), she starts asking for details.
- Cuteness Overload: Just making eye contact Kaguya can cause Erika to pass out from joy. It ended up causing a rumor among the student body that Kaguya could kill someone by looking at them.
- A Day in the Limelight: Chapter 116 focuses on her and Karen as they interview several students about the upcoming culture festival, and doubles as a Poorly Disguised Pilot for We Want to Talk About Kaguya.
- Deliberate Under-Performance: She deliberately tries to get 3rd place on the end of semester exams so her name will be listed right after Kaguya's on the class ranking (she gets 50th instead).
- Fangirl: She's a massive Kaguya fangirl.
- Given Name Reveal: She had been present since chapter 1, but her name wasn't revealed until chapter 116.
- Green-Eyed Monster: She shows jealousy over Ishigami's relationship with Kaguya in chapter 47 of We Want to Talk About Kaguya.
- Idiosyncrazy: Just about everything she does can be traced back to her obsession with Kaguya, even with things that a normal girl her age would do like studying for exams or getting a boyfriend.
- In-Universe Catharsis: Her idea of stress management is to grind up miso paste (due to her family owing a miso company).
- Innocently Insensitive: Due to her complete obliviousness over Maki's crush on Tsubasa, she believes that her depression was caused by her not being able to spend time with Kashiwagi and attempts to cheer her up accordingly. This does far more harm than good, especially when she refers to Tsubasa as Kashiwagi's "destined partner".
- Named After Somebody Famous: She's named after Kose no Oumi, a Heian era painter.
- Not Me This Time: Karen suspects that Erika was the one who sent Kaguya a love letter back in chapter 12. She actually has written hundreds of such letters to Kaguya... but she never sent any of them.
- Oblivious to Love: Erika takes this one step further. She's completely clueless to anything related to love, whether it be a boy flirting with her, Maki's crush on Tsubasa, or Kaguya and Shirogane's mutual attraction.
- Pastimes Prove Personality: Averted. Most characters are in clubs that reflect their personalities or family businesses. Erika is obsessed with Kaguya and comes from a family that produces miso paste, but she is neither in the Japanese Archery club nor the Home Economics club. In the case of the former she compares it like being too close to the sun, and the latter is because she's bad at sewing.
- Perverse Sexual Lust: Her first crush was the mascot for her family's miso company.
- Shipper on Deck: She ships Shirogane/Fujiwara and Kashiwagi/Tsubasa.
- Those Two Guys: She's rarely seen apart from Karen.
- Trademark Favorite Food: She's a big fan of anything with miso in it, owing to her family owning the in-universe equivalent of Japan's largest miso producer. This extends beyond simply eating the stuff, as her idea of stress management is to grind miso paste, and her first childhood crush was her company's mascot.
A second year student who ran against Shirogane during his reelection.
- Ascended Extra: He only appeared in two pages before Kaguya coerced him into dropping out of the race in the main series. We Want to Talk About Kaguya gave in A Day in the Limelight, giving the reader a better look at his personality.
- Break Them by Talking: Kaguya leaves him a gibbering mess when getting him to drop out of the race for student council. The fact that he indirectly badmouthed Shirogane within earshot of her probably didn't do any favors in getting her to go easy on him.
- Casanova Wannabe: The "Impossible Girls" (Osaragi, Tsubame, Momo, and Koromo) got their title because all four of them turned him down when he tried to ask them out.
- A Day in the Limelight: Chapter 58 of We Want to Talk About Kaguya focuses on his attempts to increase his chances of getting elected, before Kaguya nips it in the bud in the main series.
- Horrible Judge of Character: He tried to get an impartial jouralistic view of Shirogane from Karen and Erika, two characters whose primary character trait is their obsession with the student council.
- No Poker Face: Even Karen and Erika (who aren't exactly the most observant bunch) could instantly tell what his intentions were.
- Trauma Button: Even mentioning siraitia grosvenorii (a fruit native to China that is about 300 times sweeter than sugar) is enough to make him break into a cold sweat ever since Kaguya served him some while giving him a Breaking Speech.
Maki's twin brother.
- Always Someone Better: He's the only one in all of Japan to have scored higher than Shirogane on the last mock exams.
- Big Brother Instinct: Technichally he's the younger twin, but he travels to India with Maki to look after her, even if there are a million other things he'd rather be doing over winter break.
- Big Little Brother: He's slightly taller than Maki. Justified, since they're twins at an age where boys are normally taller than girls.
- Butt-Monkey: Maki bullies him. That alone makes him qualify, regardless of how the rest of the world treats him.
- Chekhov's Gunman: He's first mentioned way back in chapter 4 as the only person to beat Shirogane on the last mock exams, but he wouldn't have a proper introduction until chapter 161.
- Cute Little Fangs: He is briefly shown with a small fang in his introductory chapter, though this is more to show a resemblance to his sister that as any real expression of cuteness.
- Open Mouth, Insert Foot: His various comments towards Maki piss her off in a way that only a younger brother can, and she often retaliates by kicking him in the back.
- Related in the Adaptation: Being the counterpart for the emperor, he was Kaguya's love interest in the original story. Here, he's her cousin.
- Theme Naming: His name translates to "emperor", referring to Kaguya-hime's primary love interest in The Tale of the Bamboo Cutter. Also falls into Theme Twin Naming, since Maki's name contains the character for "Princess".
