High School Student Council (Kaguya Shinomiya | Miyuki Shirogane | Chika Fujiwara | Yu Ishigami | Miko Iino)
Characters appearing in Kaguya-sama: Love is War. Beware of spoilers.
Note: all characters are categorized according to Class at the beginning of the story.
Shuchi'in Academy High School
- High School Student Council
- Second-Years note
Voiced by: Itaru Yamamoto (Japanese), Jeremy Inman (English)
Debut: Chapter 14 (Manga), Episode 4 (Anime)
The current principal of Shuchi'in High School and former principal of its sister school in France.
- Adaptational Late Appearance: The anime cut out his first scene where he confiscated Karen's magazine, so he isn't introduced until the French party.
- Bunny-Ears Lawyer: He wouldn't be the principal if he wasn't competent. He nonetheless plays Pokémon GO in school and the photo shoot in Chapter 100 shows his eccentric character.
- Connected All Along: Turns out that he's Gigako's grandfather.
- Dirty Old Man: His words of praises during the photo shoot in Chapter 100, where he especially showers the girls with compliments, reveal a more perverse side of his.
- Everybody Calls Him "Barkeep": While his name is shown in several places (like Shirogane's letter of recommendation), none of the characters ever refer to him as such.
- Foreign Exchange Student: He attended the school as an exchange student 40 years before the events of the story.
- The Gadfly: He definitely seems to enjoy messing with people, as seen with his various interactions with the student council.
- Hypocritical Humor: He plays Pokémon GO during school hours, but scolds the Tabletop Gaming club for doing the exact same thing. Also doubles as Parental Hypocrisy, given that he's Gigako's grandfather.
- Poirot Speak: The anime has him pepper his dialogue with bits of random French.
- Reasonable Authority Figure: Despite being rather eccentric, he's generally fair to his students and at least able to keep order when the students and their own eccentricities bring havoc. Also, he set up the entire class 3-A where Kaguya is surrounded by her close friends just so that she can have an entire class to support her when she need them the most.
- Secret-Keeper: Seeing as how the principal let Ishigami attend high school and laughed about his "reflection", it's very likely that he is aware of Ko Ogino's true character and Ishigami's intentions in middle school. Given that his granddaughter is confirmed to have been among those that Kaguya told, he probably learned it from her.
- Shared Family Quirks: Both he and his granddaughter are fans of Pokémon GO.
- Stealth Mentor: He enlists Betsy's help to test Shirogane's worthiness of his presidential position during the French Exchange, but it backfires due to Shirogane's inability to understand Betsy's insults. In Chapter 239, he explains why; to prepare Shirogane for the task of protecting Kaguya and the school when the Shinomiya and Shijo groups inevitably go to war.
- Token White: He's the only Westerner among the cast (discounting Betsy, Hayasaka, and his granddaughter).
- What the Hell Is That Accent?: Thanks to being a native Frenchman who attended Japan as an exchange student before becoming principal, he speaks with an obvious French or at least non-Japanese accent even without the random bits of foreign dialogue. Despite his age, it still sounds akin to a European reading Japanese off a script without much prior experience.
- Yellow Eyes of Sneakiness: The anime gave him yellow eyes to underline his role as The Gadfly.
Debut: Chapter 211Kaguya and Shirogane's homeroom teacher in their third year.
- A Day in the Limelight: Chapter 225 is told from his perspective, with his attempts to be a responsible teacher towards Kaguya (and her completely misinterpreting it).
- Good Smoking, Evil Smoking: He uses an e-cigarette, showing that he's somewhat gruff but also rather young.
- Help Mistaken for Attack: His first attempt to offer advice to Kaguya leads her to assume that he's attempting to either blackmail or seduce her, similiar to how Ishigami mistook her trying to help him study for torture.
- Junior Counterpart: Inverted. He's basically an older Ishigami in terms of appearance and general demeanor, something that's further reinforced by the fact that he falls for a teacher that seems to be a hybrid of Iino and Tsubame.
- Secret-Keeper: Downplayed. He's the first person outside of Kaguya and Shirogane's immediate social circle (and Karen) to find out about their Secret Relationship, though by that point they've already started to be more open about it.
Kozue "Makki-senhai" Makihara
Voiced by: Marika Kouno (Japanese), Emi Lo (English)
Debut: Chapter 29 (Manga), Episode 13 (Anime)
- Adaptational Late Appearance: The anime cuts out her initial cameo from Chapter 29, so she doesn't appear until the adaptation of Chapter 57 at the beginning of season 2.
- Ambiguously Gay: She has shown no romantic interest towards anyone, though she does comment on how cute Iino is and playfully bites her ear during their attempt to test some horror sounds for their haunted house stall.
- The Dreaded: The Mass Media Club duo refer to the Tabletop Games Club as a "den of evil". She has a particularly bad reputation due to her sadistic personality.
- Gamer Chick: She's a member the Tabletop Games club.
- Genius Ditz: Makki-senhai may be eccentric, but she's actually one of the top 10 students of her year, with her standing even going up by one rank during the 2nd semester's final exams. She was also the first person to figure out that it was a member of the student council who took all the heart balloons.
- Ironic Nickname: "Senhai" was originally "senpai" but the "pai" was stollen in a punishment game. She's actually a freshman.
- Known Only by Their Nickname: She rarely goes by her real name.
- A Mother to Her Men: Parodied. During the sports festival, her club prepared randomized beverages, apparently to so amuse the competitors while hydrating them. None of them went along with the idea, though note , so Makki drinks one herself.(coughing) "I am the TG Club's eternal president. I can't waste something you put this much effort into...That is all."
- Turns out it was just miso soup. She's fine.
- Nightmare Fetishist: She has an unhealthy love for horror. Case in point: her idea for the culture festival was a school wide battle royale death match.
- Otaku: She is a "mega otaku" according to Fujiwara.
- Sadist: She basically subjects Iino to softcore BDSM when they were recording ASMR for their class's haunted house, and was clearly loving every second of it.
- Those Two Guys: Rarely seen without Gigako.
- Young and in Charge: She is the "Dictator for Life" of the Tabletop Games Club, despite being a first-year. She presumably won the title by beating the others in a board game.
Voiced by: Rina Hidaka (Japanese), Leah Clark (English)
Debut: Chapter 65 (Manga), Episode 12 (Anime)
Miko Iino's childhood friend who serves with her on the Shuchi'in Disciplinary Committee and acted as an assistant for her presidential campaign. Prefers to watch from the sidelines.
- Adaptational Early Appearance: She can be briefly seen during the credits sequence of the anime's first season finale, which is set 19 manga chapters before her introduction.
- Affectionate Nickname: Iino calls her "Koba-chan".
- All of the Other Reindeer: Osaragi describes herself as a pariah amongst the other girls in school in Chapter 189.
- Bad Guys Do the Dirty Work: Invoked on herself. Osaragi takes the secret student council file about Ishigami and gives it to Tsubame, because she supports their relationship. She tells Kaguya that, since it would have strained the relationship between Ishigami and the rest of the council if one of the council members had done it, she decided to do it herself.Osaragi: The perfect role for the perfect pariah, wouldn't you say?
- Batman Gambit: Played for laughs. Iino and Ishigami don't get along, so in Chapter 103 Shirogane proposes several activities that are supposed to make them become friends. As all attempts fail, Osaragi points out the Belligerent Sexual Tension between them with a "Not So Different" Remark to end this farce. The two of them then deny Osaragi's observation by claiming in front of Shirogane that they actually like each other, just as Osaragi expected they would behave.
- Beautiful All Along: The reader cannot see her face behind her Opaque Nerd Glasses and stereotypical geeky looks, but in-universe she is viewed as a very attractive woman both by the boys in school and her female friends. Her face is shown in full at the end of chapter 231, and she is indeed very pretty.
- Because You Were Nice to Me: Her middle school life was full of people who resented her for her good looks. The few people who managed to help her through this phase were Iino, Otomo, Ishigami and Tsubame and it's due to their kindness that she's incredibly loyal to all of them. She now supports the relationship with Ishigami and Tsubame, despite having developed feelings for him.
- Beneath Notice: Next to a loudmouth firecracker like Iino, not many people notice Osaragi, which is just the way she likes it. She knows the downside of fame all too well.
- Birds of a Feather:
- Osaragi sees herself as a kind of pariah, which is why she can take on the role to tell Tsubame the truth about Ishigami's past without any damaging consequences. Kaguya points out that Ishigami and Osaragi are thus very similar, which Osaragi agrees with.
- Tsubame offered Osaragi help in middle school, as both were resented by people who were jealous of their looks and achievements. Tsubame then advised Osaragi to brush off their compliments with an indifferent "thankful" reply, and told Osaragi to lean on her if she ever needed to.
- Iino is another social pariah, as her obsession with the rules makes her fairly unpopular, which is largely why she and Osagari bonded and became friends in the first place. However, with Iino getting more popular and the two of them conflicting over Iino's crush on Ishigami, Osaragi starts to feel that they were only ever friends in name only, and without a shared social status they have nothing in common.
- Brainless Beauty: She's considered to be one of (if not the) most beautiful girls in school, yet her ranking on the end of semester exams are pitiful (she actually ranks below Ishigami). Given the fact that she's actually shown to be rather observant otherwise, it might be a case of her just not caring about academics, but nothing concrete is ever stated.
- Broken Bird: Chapter 192 reveals that Osaragi used to be a cheerful and outgoing person, but this all changed when the tabloids published the news that her mother cheated on her husband, making Osaragi the subject of Condescending Compassion in addition to the jealousy other girls showed her in middle school. Since then, she has become more introverted.
- Broken Pedestal: In a way, towards Iino. She silently supported Iino and Ishigami as a pair in middle school despite having feelings for the latter due to them fulfilling what her ideal romantic relationship looks like. However, when Iino doesn't take Ishigami's side when he gets ostracized, Osaragi becomes deeply disappointed in her for not repaying all of Ishigami's efforts to help her out (despite Iino not being aware of said efforts in the first place), and has grown to resent her ever since.
- Cannot Spit It Out: Osaragi never gains the courage to tell Ishigami about her feelings for him. It's confirmed in Chapter 232 that she refrained from doing so in middle school because she saw how much more compatible Ishigami and Iino are and tried to make way for them, and in high school she notices that Ishigami has fallen for Tsubame. The closest thing she gets to a confession is her admitting in Chapter 192, that she has known his true self for a long time, and wishes for his happiness.
- Childhood Friends: She's been friends with Iino ever since elementary school.
- Cloudcuckoolander's Minder: Most of her on-screen interactions with Iino have her reigning in her friend's overactive imagination. She mentions during the end of the culture festival arc that she's going to try to stop doing this as often, as she feels that it's keeping Iino from growing up.
- Condescending Compassion: A victim of it in middle school. After her mother's affair was revealed, lots of female classmates might have said they were sorry but their tones said they thought Osaragi deserved it due to their jealousy of her beauty.
- The Confidant: Acts as this to Iino, who tells her everything that's troubling her. However she avoids doing so when Iino needs advice about her conflicting feelings for Ishigami without making it obvious to her. The reason is that Osaragi has placed Ishigami's happiness over everything else, and she's not going to risk his chances of him getting together with Tsubame by helping Iino.
- Conflicting Loyalty: Chapter 192 shows the dilemma Osaragi is in. On the one hand, she would like to support her Childhood Friend Iino, but Iino has fallen for Ishigami, for whom Osaragi herself has feelings for, and he is in love with Tsubame, who has also helped Osaragi out in the past. Osaragi prioritizes Ishigami's happiness over everything, though, thinking that he has made the "right" choice in falling for Tsubame, which is why she supports his potential relationship with her.
- Courtly Love: Her admiration of Ishigami is more philosophical than physical (although there's a bit of the latter too) and she feels similarly about the girls who also helped her.Ishigami: The unconditional love within each person's chest...why can't people realize that's what true love is?
- Covert Pervert: When Iino complains that (she thinks) Shirogane and Ishigami use the student council to take advantage of its female members, Kobachi suggests "joining in on the fun", and describes it as "a pretty hot situation". This could be yet another piece of Foreshadowing about her unrequited feelings for Ishigami.
- The Cynic: Her thoughts on mob mentality are rather depressing, as she witnesses how Ishigami is ostracized by the female first-years. Osaragi later implies that she is also a pariah in school, as she was harassed after her mother's affair became public, on top of all the jealousy, hatred and insincerity other female students showed her in middle school.
- A Day in the Limelight: Chapter 85 features a day in the life of her role as a member of the disciplinary committee. Chapter 192 is also told from her perspective and reveals a major part of her past. Chapter 232 has her disclose to Kaguya her perspective on Ishigami and Iino's relationship in middle school.
- Deadpan Snarker: Basically Iino's straight-man, although she has her own quirks.
- Disappeared Dad: The fanbook lists her mother as her only relative. Chapter 192 implies that her father left after news of her mother having an affair was published in a tabloid.
- Dude Magnet: Onodera reveals in Chapter 158 that Osaragi has a lot of boys fawning over her, including guys from other school who wait at the gate just for a chance of catching a glance of her or asking her out.
- Fallen Princess: Seeing the malice of people when her family broke up almost embittered her. Except she also saw that some people were truly good.
- Foil: Chapter 192 reveals her to be one to her best friend, Iino:
- Their issues are the result of their families with Iino's self-righteous attitude and starvation for affection due to her parents' busy schedules while Osaragi's status as a pariah is due to her mother's affair as well as her beauty that she inherited.
- They are both pariahs who were especially bullied in middle school but while Iino was able to get through with her personality mostly intact, Osaragi became heavily introverted as well as distrusting due to it.
- Both are weak to people that are kind to them but while Iino is weak to any compliments no matter how obviously fake they are, Osaragi is completely loyal to the few people that helped her in her darkest hour.
- They both have a crush on Ishigami due to minor things he's done. Iino crushing on him unknowingly due to a simple letter and flower he sent her as well as checking up on her during the culture festival with pictures of people enjoying the bonfire, she worked so hard to get approved. Osaragi fell for him due to him protecting her from some bullies as well as his general kindness.
- They're both similar to their crush but in different ways which changes how they interact. Iino has similar ideals of altruism and is just as stubborn but that makes them argue each time they meet because they're too similar. Osaragi is just as observant and distrusting of others which allows them to interact peacefully on the rare occasion they cross paths.
- They have exact opposite reactions to Ishigami's crush on Tsubame. Iino getting deeply jealous over it and early on trying to get in their way compared to Osaragi's full support.
- Former Child Star: Chapter 192 shows that she was an outgoing and lively Child Popstar, but her mother's affair and not having the social skills to deal with her classmates' resentment led to a terribly depressing time in middle school.
- Given Name Reveal: Despite being introduced in and a recurring character since Chapter 65, her name wasn't revealed until Chapter 85.
- Green-Eyed Monster: In Chapter 232, she admits to Kaguya that she's always been incredibly envious of Iino for being Ishigami's Protectorate, and claims that if she were in her position she would have taken his side and believed in him when the Otomo incident happened.
- Hollywood Nerd: With her braided hair, her Opaque Nerd Glasses and her conservative style of wearing her uniform, Osaragi comes off to the reader as this, but in-universe, she is seen as a very attractive woman who has lots of boys fawning over her. Onodera is surprised to see that despite her looks, Osaragi is actually very nerdy.
- Hyper-Awareness: As she has known Iino since elementary school, she knows her friend quite well. She also pays a lot of attention to Ishigami, after he defended her in middle school. This is why she knew he was the one who sent Iino the letter and flower that showed Iino the appreciation she desperately craves.
- Hypocrite: She disapproves of Miko's recent attempts at trying to get closer to Ishigami as she sees it as Miko taking advantage of Ishigami's feelings after Tsubame rejected him not too long ago. This, coming from the same girl who played with Kazeno's feelings just so Ishigami would have one less potential competitor for Tsubame's affections and later encouraged Ishigami to take advantage of Tsubame's weakness to pressure so Tsubame wouldn't reject his confession a few months back.
- She's actually aware that she's one, admitting that while her resentment of Iino is due to the latter not taking Ishigami's side when the Otomo incident happened (at least initially), she didn't actually do anything to help him either, which explains that for the same reason she vetoes Iino as Ishigami's girlfriend, she forbids herself.
- I Just Want to Have Friends: She is as deeply interested in her peers' lives as your average teenage girl, but she fears the vulnerability that true friendship entails. From a distance, she can steer them in the direction she wants without risking attachment.
- Indifferent Beauty: She has a rather nonchalant attitude towards the fact that boys find her attractive, so much so that the audience doesn't learn about it until almost 100 chapters after her introduction. This kind of attitude was recommended to her by Tsubame, who faced similar problems of resentment.
- Informed Attractiveness: Used as a joke when both Iino and Onodera comment on how beautiful she is. Since her glasses are drawn opaque and cover most of her face, readers can't tell. In fact, she is known as one of Shuchi'in High's four "Impossible Girls", the most beautiful girls (excluding the student council members) that are impossible to date.
- Insecure Love Interest: Osaragi started looking at Ishigami, after he defended her against bullies in middle school. She seems to hold back her feelings because she thinks Ishigami made the right choice in choosing Tsubame. Even back In middle school, Osaragi assumed Ishigami was interested in Iino after she saw him sending Iino the letter.
- Intentional Heartbreaker: It's heavily implied that the only reason she went out with Kazeno was so he wouldn't get in the way of Ishigami asking out Tsubame. Once that goal was achieved she promptly dumped him without any consideration for his feelings.
- I Want My Beloved to Be Happy: Chapter 192 reveals that, while Osaragi has feelings for Ishigami, she decided to not act on them, after seeing that Ishigami was the one who sent Iino the flower and letter that she treasures above all. When she learns that he is interested in Tsubame, she tries her best to make him happy, and supports him without his knowledge.
- Jerkass Ball: Actively attempting to get Ishigami and Tsubame together despite knowing Iino has a crush on the former is a pretty mean thing to do to her best friend. As can be seen in Chapter 190, she also refuses to talk with Iino about her clearly hurt feelings, instead openly stating that she ships Tsubame and Ishigami. And even after her ship fell through, she still refuses to support Iino's efforts to get closer with Ishigami, and badmouths her behind her back.
- Jerkass Has a Point: While claiming in Chapter 229 that she still can't support Iino's crush on Ishigami even after her own preferred ship fell through may sound like a horrible thing to say regarding her best friend, both of the points she makes on why she can't (Ishigami would just be On the Rebound and Iino is trying to take advantage of the situation) are completely valid.
- Love Makes You Evil: Chapter 192 reveals that Osaragi has feelings for Ishigami and wants to help him gain happiness by helping him get into a relationship with Tsubame. It's heavily implied that her sudden and short-lived fling with Kazeno was sorely intended to remove him as a potential romantic rival and improve Ishigami's chances with Tsubame. She also prioritizes Ishigami's happiness over her best friend Iino's, and willingly ignores Iino's desperate need to talk about her feelings, while openly telling her that she supports Ishigami's relationship with Tsubame.
- Meaningful Name: The Buddha mentioned in Osaragi's name taught that attachment (to anything, even people) causes suffering. An ethos Osaragi can surely get behind.
- Minor Flaw, Major Breakup: She broke up with Kazeno because she was grossed out by his workout regimen. Though once her feelings and intentions for Ishigami are revealed, this sounds more like an excuse she needed to break up with someone she wasn't interested in, especially because she didn't seem grossed out looking at Ishigami (with a Crush Filter) working out in Chapter 85.
- Motherly Side Plait: Osaragi isn't actually a mother, though her use of the hairstyle does help reflect how she acts as Iino's Cloudcuckoolander's Minder.
- Nothing Personal: She didn't want to hurt Kazeno's or Iino's feelings...she just didn't care if she did.
- One Thing Led to Another: This is more or less how she started dating Kazeno, though there (probably) wasn't any sex involved.
- Only Friend: Iino didn't have anyone but Osaragi before joining the student council. In Chapter 137, Osaragi mentions that she acts a bit too overprotective towards Iino and wishes that Iino becomes more independent, so she can grow.
- Only Sane Woman: She's level-headed and perceptive, which gives her a generally accurate picture of the rest of the cast and lets her cut right through the comedic misunderstandings. When Iino came to her claiming that the student council was some kind of weird sex club, Osaragi pointed out how out-of-character that sounded and encouraged Iino to re-evaluate the situation. She's also observed what kind of person Ishigami really is (like seeing him quietly pull a mocking sign off Iino's back), and as a result doesn't believe the rumors that he's a violent stalker.
- Opaque Nerd Glasses: Her eyes have never been seen in story (though half of her right eye is visible on the cover of Volume 17). This doesn't keep her from being considered a Dude Magnet (despite a yonkoma packaged with the anime's DVDs stating it's the entire reason she wears them). A side view of her face can be seen in Chapter 192, right after she gave Ishigami a roundabout confession. Osaragi's face is clearly seen for the first time at the end of Chapter 231, after she opens up to Kaguya.
- Opposites Attract: She's a somewhat quiet girl, not the sort of person you'd expect to be dating the captain of the cheer team. Of course, it's likely that she never had any interest in him to begin with and was only dating him so he wouldn't be a threat to Ishigami asking out Tsubame. Once that goal has been achieved, she promptly dumps him.
- Psychological Projection: The real reason behind her Shipper on Deck support for Ishigami×Tsubame. It's confirmed in Chapter 231 that Osaragi sees Tsubame a successful version of herself — that is, someone who had the same kind of envious attention she suffered from in middle school focused on her, but was able to handle it without making it into her Cynicism Catalyst — and considered seeing Tsubame in a relationship with Ishigami to be the closest Osaragi herself was going to get to having her feelings for him fulfilled.
- Refusal of the Call: Shirogane offered her the position of General Affairs Officer after his reelection, but she turned him down, as she had no interest in being on the council. The position has remained unfilled ever since.
- Scary Shiny Glasses: Osaragi is The Faceless, due to her glasses. As her eyes are hidden, it's difficult to see her emotions outside of the rare smiles she shows (which are often directed at Ishigami). A part of her eyes can be seen in the Volume 17 cover, though, and in Chapter 192 a clear side view of her face is shown when she tells Ishigami that she wishes for his happiness. Her face is clearly shown at the end of chapters 231 and 232, reflecting how she's finally opened up about her emotions and insecurities to Kaguya.
- Osaragi took the secret student council report about Ishigami and then gave it to Tsubame, so she is fully aware of what exactly happened between Ishigami and Ogino in middle school.
- Up until Chapter 192, she was a Secret Secret-Keeper to Ishigami. Osaragi tells him that she knew he was the one who sent Iino the encouraging letter and the flower back in middle school. It's implied that she didn't tell Iino because of her own feelings for Ishigami.
- Seen It All: She is accustomed to Iino's tendency to make mountains out of molehills.
- Shadow Archetype:
- To Ishigami. Osaragi is a victim of mockery and an Otaku, who hides behind her appearance and shut the world out, which is why many people appear or used to appear like The Faceless to her, just like with Ishigami. Like him, she can be very observant and wants to support her loved one without their knowledge. Even their Leitmotifs are similar, and they placed similarly in the exams in Chapter 105, with Osaragi being 151st and Ishigami being 152nd. However, Ishigami moved on from his insecurities and asked his crush out, which is something Osaragi wasn't able to do. He also puts an effort in to socialize more, while Osaragi still appears to be very introverted.
- Also to Tsubame, with both being one of the beautiful "Impossible Girls" in school, but unlike Osaragi, Tsubame is The Social Expert, who was able to withstand the jealousy of others and remained cheerful, while Osaragi became more introverted and cynical. Osaragi herself is well aware of this, and later admits to shipping Tsubame/Ishigami as a means of Psychological Projection.
- Chapter 231 reveals her to be one to Kaguya as well, representing who she'd be if she didn't care about Fujiwara as a person, and only befriended her for the sake of having friends, or if she didn't stop seeing her as a rival for Shirogane's attention.
- Shipper with an Agenda: She seems to ship Ishigami and Tsubame, going so far to give Tsubame the secret report the student council made about Ishigami and the reason for his actions in middle school. She does this, despite being aware of the Belligerent Sexual Tension between Ishigami and her best friend, Iino, and Iino's growing feelings for Ishigami. Chapter 192 shows how Tsubame helped her dealing with the envy of her classmates, and how Ishigami defended Osaragi from others talking behind her back. She thus decided that Ishigami, whom she has feelings for, made the right choice to fall for Tsubame and court her.Osaragi: IshiTsuba is absolute! I'm on this ship and never getting off!
- Shipping Torpedo: While she does want Iino and Ishigami to get along, she's against Iino realizing that she's in love with him because she ships Ishigami with Tsubame. Chapters 231-232 also show that she doesn't want them to become a couple because she's jealous of Iino, and believes that she doesn't deserve Ishigami due to not siding with him when he was ostracized in middle school.
- Single-Target Sexuality: It's implied that the reason why she's considered to be a member of the "Impossible Girls" is because she's only romantically interested in a single person, specifically Ishigami.
- Single Woman Seeks Good Man: Chapter 192 has her indirectly admit that she likes Ishigami because he defended her in middle school when people ridiculed her behind her back as well as his kindness to everyone, such as him helping her best friend Iino behind the scenes.
- Smart People Wear Glasses: Inverted. Despite wearing Opaque Nerd Glasses and sometimes showing that she can be very observant when it comes to other people, she's actually among the bottom quarter of the freshman class in terms of grades.
- So Beautiful, It's a Curse: In Chapter 192, Osaragi describes herself as a girl who couldn't handle the jealousy other girls showed her, until she got fed up with it and hung out with the boys, which only made things worse until she was isolated. Tsubame was the one who told her how to deal with this.
- Sympathy for the Hero: She is fond of people who take initiative in improving the world, but she does not see herself as one of them. You could say she's relegated herself to being a minor character in their story.
- Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Ishidzukuri no Miko (Iino's namesake)'s task item, the Begging Bowl of the Buddha (bu no miishi no hachi)note .
- Too Much Alike: She does the same thing to Ishigami that he has been doing to everyone else, a realization which fills him with abject horror.
- The Unfettered: She does not fear her sight, and likely even wears glasses to enhance it.
- Unfortunate Names: Her name can also be read as "Daibutsu"note but she'd very much prefer that it wasn't.
- Used to Be More Social: If one compares how she introduces herself in Chapter 85 to how she did in Chapter 192 when she was a cheery and social Child Popstar, one can easily see how the ridicule and jealousy she received in middle school took a toll on her.
- Walking Spoiler: Half of her entry is whited out due to being a vastly different character than she's initially presented to be.
- The Watcher: She doesn't actively participate in plots, but she does take notice of all the things going on with Iino, and the situation in middle school. Thankfully, this means she can see the good points of those who are shunned, like Iino and Ishigami. This also means she sees the Belligerent Sexual Tension between the two of them.
- We Used to Be Friends: Her friendship with Iino seems pretty okay at first, but ever since Osaragi's opposition of Iino getting closer to Ishigami, the two start drifting away from each other. This goes to the extreme by chapter 231, where Osaragi reveals her disdain of Iino to Kaguya, and Iino just so happens to walk in on the conversation. Iino calls out Osaragi's own refusal to act like a friend recently, and simply states that she has more friends now. Suffice to say, their friendship has become a hollow shell of what it used to be though they're fortunately able to resolve some of their issues by the end of the arc.
- World's Most Beautiful Woman: The bonus page for Chapter 158 goes so far as to claim that she is rumored to be the hottest girl in the history of Young Jump (the magazine that the series is published in).
- Yaoi Fangirl: In one of the extra comics, Osaragi is seen reading a BL manga, and is quite into it.

- Adaptation Dye-Job: In the manga she has light pink hair and blue eyes, while the anime made both of them yellow.
- Armor-Piercing Question: In Chapter 230 she delivers one to Ishigami that not only makes him realize that Iino matters too much to him to not take action if there's a chance she's in trouble, it leaves him to start wondering who Iino is to him."Is Iino just 'someone else' to you? Are Kyoko Otomo and Miko Iino both just the same to you?"
- Bully Turned Buddy: Downplayed, as while she was never a bully per se, she did help to perpetuate Malicious Slander about Ishigami and Iino due to her love of gossip. She later befriends both of them when she gets to know them better and she ships them together.
- Character Development: Due to her curious nature, Onodera was a Gossipy Hen and blindly believed rumors that she picked up on, talking badly about Iino and Ishigami behind their backs. However, after getting to know them better and becoming friends, she learned that the rumors about Iino and Ishigami are nothing but Malicious Slander that she helped spread and she in turn has become more introspective and careful regarding rumors and secrets.
- Constantly Curious: She's far more stoic than most examples, though she makes a habit of learning about others' hobbies, even if it's something that she would normally never show interest in (like reading light novels). This also ties into her love of rumors, though she mentions in Chapter 172 that she's been trying to avoid spreading baseless accusations.
- Curtains Match the Window: In the anime, she has blonde hair and yellow eyes.
- Dub Personality Change: She's initially hostile to Ishigami in the manga and the initial airing of the anime to showcase the treatment he receives from his fellow first-years, but in the English dub she acts more surprised that he's acting so carefree despite what happened back then.
- Early-Bird Cameo: She shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (she's the one standing next to Osaragi).
- The Faceless: Averted. She's the only member of the Cheer Team whose face Ishigami could see prior to the sports festival (presumably because he is already familiar with her as a classmate).
- Foil: When it comes to their friendship with Iino, she serves as one to Kobachi Osaragi:
- Onodera is outgoing and social albeit still reserved, while Osaragi tends to be more withdrawn and distant towards most people.
- She's among one of the popular kids in high school. Osaragi, while known as one of Shuchi'in's "Impossible Girls", was initially a pariah in her middle school days.
- Osaragi is Iino's childhood friend and has been by her side for most of her early life, but is not supportive of her growing feelings for Ishigami, choosing instead to support a potential relationship Ishigami could have with Tsubame. As a result of that, she and Iino slowly grow distant from each other as the manga continues, and have barely hung out, at least onscreen, since Osaragi made her stance clear. Meanwhile, Onodera and Iino have only known each other in less than a year, initially had a somewhat frosty start together partly due to Onodera hearing and spreading bad rumors about her, and both come from completely different social circles, yet once they bonded and got to know each other better, Onodera becomes a faithful and supportive friend to Iino, growing closer to her as the series progresses. The big difference here that sets her apart from Osaragi is that Onodera fully supports Iino/Ishigami without any ulterior motivations whatsoever aside from wanting Iino to be happy, while Osaragi vetoes the pairing, and has other things in store for Ishigami that she thinks is best for him.
- Inconsistent Coloring: Her Early-Bird Cameo in the anime had her with pink hair like she what she has in the manga, but when she's properly introduced she's suddenly become a blonde.
- Ms. Exposition: She fills this role regarding the Iino/Ishigami/Tsubame Love Triangle. Being a member of Tsubame's social circle, she's able to fill in Iino and Ishigami with information about her that they would otherwise never learn.
- Not So Stoic: In contrast to her usual demeanor, she is notably more cheerful when on the Cheer Team or the culture festival committee. Not to mention the fact that she suggested a meme as the latter's slogan.We got dank vibes!! ~Shuchi'in is lit af~
- Odd Friendship: While the two of them have almost nothing in common and come from completely different social circles, she and Iino grew rather close while on the Culture Festival committee together. Iino affectionately calls her "Rei-chan".
- Ojou Ringlets: Being a Shuchi'in student, it's only natural she rocks the long-haired drill style. Though as the series went on, her hair became looser and looser until the curls were all but gone.
- Perpetual Frowner: She doesn't smile much and is mostly seen wearing a neutral frown on her face.
- Right for the Wrong Reasons: Upon hearing Iino's Innocent Innuendo laden description of how she had spent the previous night with an older man, she comes to the conclusion that she must have gotten herself a sugar daddy. Iino was actually talking about learning how to play Apex Legends from Papa Shirogane, who has called himself "Sugar Daddy" multiple times in the past.
- Secret-Keeper: She finds out about Kaguya and Shirogane's relationship after hearing the former sleep-talking about it, later getting indirect confirmation when she goes to ask her about it. The fact that she keeps it a secret from Iino when she walks in on the conversation puts her on Kaguya's good side.
- She Knows Too Much: Non-fatal example. After revealing that she knows about Kaguya and Shirogane's Secret Relationship, Kaguya nearly assaults her with a taser to give her Laser-Guided Amnesia (only for her to prove that she can function as a Secret-Keeper while remaining completely oblivious to Kaguya's attempted attack).
- Shipper on Deck: She ships Ishigami/Iino, something that becomes especially apparent during Tsubame's Christmas party, where she gets in-between Iino and a boy who tries to flirt with her, and is constantly focused on Ishigami and Iino's conversations. Notably, when a shipping war broke out between those who supported Ishigami/Tsubame and Ishigami/Iino in Chapter 189, she was the only one who had no ulterior motives.
- Small Role, Big Impact: In hindsight, Onodera confronting Kaguya about her Secret Relationship with Shirogane might have significantly influenced Kaguya reconsidering her toxic thinking about subjecting potential friends to a Secret Test of Character, and how she can only truly regard Secret Keepers as friends. As Kaguya learns at the end of the class trip in Kyoto, Hayasaka has been reporting almost everything about Kaguya to her eldest brother, Oko. However, Kaguya manages to forgive Hayasaka and listen to her, and they remain Heterosexual Life-Partners.
- Sweater Girl: Onodera's most prominent physical characteristic is the buttondown sweater she wears during the colder months.
- You Gotta Have Blue Hair: Her hair is pink in the manga.
Debut: Chapter 166 (Manga)
A popular first-year student, considered to be one of the most beautiful girls in school.
- Chekhov's Gunman: Her name is first listed on the end of semester exams in Chapter 105 right under Onodera. She is mentioned to be one of the school's four impossible girls and properly appears in Chapter 211.
- Commonality Connection: She ends up becoming friends with Ishigami after the two of them meet on a gaming Discord server.
- Gamer Chick: Chapter 228 reveals that she's an avid online gamer. It's implied that the tired look in her eyes is due to constantly staying up late to play.
- Girls Love Stuffed Animals: A single panel shot of her bedroom in Chapter 228 shows that she has at least one teddy bear.
- I Never Told You My Name: She calls Ishigami "Yuu-chin" when they meet on Discord even though he only gave his last name. While it's likely that she'd know of him due to him being a member of the student council and the Ootomo incident, the fact that she immediately goes for First-Name Basis is definitely suspicious.
- Informed Attractiveness: She is known as one of Shuchi'in High's four "Impossible Girls", the four most beautiful and unapproachable girls in school, on par with the girls from the student council.
- In the Hood: She usually wears a hooded jacket over her school uniform, which kept her features completely hidden from the reader during her first appearane.
- Mistaken for Romance: While chatting with Ishigami at school the day after they're introduced to each other, some poor wording on her part leads all their classmates (except Osaragi) to assume that they're Friends with Benefits.
- School Idol: She's considered to be "The Fairy of the First-Years" by Erika, on par with the likes of Kaguya and Tsubame. Given that Erika worships the very ground that Kaguya walks on, this is high praise indeed.
- Ship Tease: very friendly with Ishigami when they met online. Quickly seen as a threat by Iino, while Osaragi and Onodera see potential for her as Ishigami's girlfriend.
- Signature Headgear: She has two ribbons in her hair, even using a picture of one of them as her Discord icon.
- Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Abe no Miushi's task item, the robe of the fire rat.
- Unseen No More: She's been mentioned a few times, but at most she's only been seen from behind during an Imagine Spot in Chapter 166 wearing a sweatshirt that hides everything but her hands. This is finally subverted in Chapter 211 when she finally shows up in person. She presumably works in show business, which would be the reason why she doesn't attend classes often and thus was absent until then.
Voiced by: Haruka Fukuhara (Japanese), Tia Ballard (English)
Played by: Haruka Fukuhara (live-action movie)
Debut: Chapter 82 (Manga), Episode 17 (Anime)
A perky upperclassman that leads Ishigami's group through sports day. Caring and energetic, she captures Ishigami's heart quickly.
- Academic Athlete: She's ranked seventh among the senior class and is a member of the school's rhythmic gymnastics club.
- Adaptation Dye-Job: Her hair is brown in the live-action movie.
- Ascended Extra: After the sports festival arc, she gets more characterization during "Kaguya Shinomiya's Impossible Tasks".
- The Bartender: Her father is a world-famous bartender, so she's presumably been taught how to prepare drinks from a young age. When she hosts a Christmas party, she spends the entire time in a waitress outfit making (non-alcoholic) beverages for everyone and even shows Ishigami how to properly use a cocktail shaker.
- Beneath the Mask: While generally a cheerful Genki Girl, there is a hint that when it comes to relationships, she hides the emotional scars her previous relationship left, which is the reason for her commitment issues.
- Betty and Veronica: She's the Veronica to Iino's Betty and Ishigami's Archie. She's a comparatively newer presence in Ishigami's life who has the looks, grades, and popularity to make her appear unnaittanable to someone like Ishigami, but this does not deter him from pursuing her anyway.
- Birds of a Feather: Chapter 192 reveals that Tsubame reached out to Osaragi, since she saw a connection between them in middle school, as girls who are belittled and harassed by students with an Inferiority Superiority Complex. She then gave Osaragi advice on how to handle it and offered to help if Osaragi ever needed it, which Osaragi was truly thankful for.
- Cheery Pink: Her hair has a light pinkish tint. Fittingly, along with Kazeno, she's the co-leader of the Cheer Team.
- Clear Their Name: She restores Ishigami's good name as a gift to make up for turning down his love confession by using her social influence to alter the narative of what happened during the Otomo incident to a more accurate (though still ultimately untrue) story.
- Commitment Issues: Her previous boyfriend cheated on her (and it's implied that the other girl in the equation was her best friend). Because of this, she was rather hesitant to accept Ishigami's Love Confession and ended up giving a rather lame excuse to turn him down. Chapter 160 has her admit that she was always confessed to, but never confessed to someone else. Confessions scare her, because she views them as binding contracts, and she is too indecisive to make such a decision herself.
- Cuddle Bug: She has no reservations about getting in her friends' personal space when being affectionate.
- The Ditherer: Insecure/Submissive type. One of Tsubame's issues is that she gets very nervous and stressed, and doesn't know what to do when she has to make important decisions like after Ishigami seriously confesses his feelings to her. She asks the people around her, like Kaguya or Shirogane's father (who works as a fortune-teller and online relationship adviser), for advice and is easily influenced. Unfortunately, her indecisiveness leads to questionable actions, like not willing to commit to a relationship yet offering Pity Sex to Ishigami, which he rejects as he doesn't want her "half-assed love".
- Dude Magnet: Kaguya notes that she's very popular, as demonstrated in Chapter 115 when Ishigami is competing against three other boys for her attention.
- Early-Bird Cameo: She shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (she's the only one of the third-year students whose hair isn't black).
- Even the Girls Want Her: Several girls are shown squeeing alongside Ishigami over her dance performance during the culture festival in the omakes, and she got a pile of chocolates that rivaled that of Shirogane on Valentine's Day.
- The Faceless: As with the rest of the cheer team, in the sports festival arc. She only gets her face properly shown after Ishigami "opens his eyes" to the world again.
- The First Cut Is the Deepest: Her previous boyfriend cheated on her and it's implied that the girl he slept with was her best friend, explaining why she was so hesitant to accept Ishigami's Love Confession (and why she thought that offering to sleep with him was a good solution).
- Genki Girl: She's constantly upbeat and loves to try new things. It comes with the territory of being a member of the cheer team.
- The Heart: As the leader of both the Cheer Team and the Culture Festival Committee, she serves to bridge the tension between most of the members and the more unliked Ishigami and Iino respectively.
- I Don't Want to Ruin Our Friendship: This is the reason why she's so hesitant to give Ishigami a definitive answer when he unknowingly confesses to her. She isn't really sure if she's romantically attracted to him (along with other issues like the fact that she's going to be graduating soon), but she knows that turning down such a heartfelt confession would break his heart and destroy their already existing relationship. Her attempts to ask Kaguya for advice don't really help due to a case of One Dialogue, Two Conversations.
- Important Haircut: She stopped wearing her hair ribbon cut her hair to chin length (save for the sidelocks) after graduation. Ishigami describes it as making her look more grown up.
- Informed Attractiveness: As Tsubame's name is clearly a reference to one of Princess Kaguya's impossible tasks, she is one of the four "Impossible Girls" in school, the four most beautiful women of Shuchi'in High (excluding the student council members) that are impossible to date.
- Insecure Love Interest: Unlike previous confessions, she takes Ishigami's very seriously, since he earnestly has feelings for her. However, she isn't ready to commit to a serious relationship (due to how the relationship with her previous boyfriend ended), which is why she rejects his confession on Christmas Eve. She ends up hurting Ishigami because despite not reciprocating, she offers to have sex with him out of sympathy. Chapter 191 elaborates on that, where she admits that while she does love Ishigami, she cannot clearly distinguish between platonic and romantic love. Tsubame wants to act responsible, since she's the elder one in the relationship, but her friends are not helping at all, forcing her to ask a stranger (Shirogane's father) for advice.
- Like Brother and Sister: She and Kazeno are close friends, though their relationship is completely platonic.
- Long-Distance Relationship: Defied. The reason why she ultimately turns down Ishigami after the Christmas party is because she's graduating and going away to college in three months. She doesn't feel that such a relationship would work out in the long run. It's worth pointing out that she is lying about this and just using it as a cover for her Commitment Issues (since the college is less than half an hour away by train, and she already told Kaguya before that such an excuse would just sound like a roundabout way to tell him that she doesn't like him romantically).
- Maybe Ever After: Her live-action counterpart retains her role as love interest for Ishigami, and with Iino's heavy demoting is the only love interest for him in the second movie. They don't exactly get together, but ship tease is heavy and they have a Dance of Romance at the school festival.
- Ms. Exposition: She explains to Kaguya the legend and theme of the Devoted Hearts Festival and how High-School Sweethearts can be granted eternal love during the festival, like with what happened with her older brother and sister-in-law.
- My God, What Have I Done?: At the end of the Christmas party, she immediately regrets offering Pity Sex after Ishigami properly confessed and asked her to date him. Disappointed and irritated, he leaves, at which point she realizes that she just seriously hurt his feelings.
- Nice Girl: She accepted Ishigami easily despite the rumors surrounding him, which is why he starts falling for her. She also helped both Osaragi and Momo in the past, thought the details for the latter have yet to be revealed.
- Nightmare Fetishist: She's apparently a fan of horror stuff, and gets really excited when Ishigami invites her to try out his class's haunted house at the culture festival.
- No Sparks: This is ultimately the reason why she turns down Ishigami's Love Confession. Despite how much she may like him as a friend, she just doesn't have any romantic feelings for him.
- Not So Above It All: Tsubame is normally a nice and understanding girl, but hilariously enough, just like everyone else, she tells Kazeno off for jumping over a railing while wearing a skirt - which caused him to sprain his ankle right before a relay event - by calling him a moron for it.
- Oblivious to Love: Tsubame doesn't realize that Ishigami has a serious crush on her. After he confesses to her, she doesn't know whether she likes him platonically or romantically, because she can't distinguish them. Her friends aren't any help at all, as one of them doesn't have any experience, either, and the other one suggests sleeping with him, which she tries to do. Not only did it not help Tsubame find her answer, she ended up hurting Ishigami.
- Passionate Sports Girl: She's a member of the school's rhythmic gymnastics club.
- Retail Therapy: Papa Shirogane describes her as the type who goes impulse shopping while under stress while telling her fortune. This comes up at least twice, both times involving her relationship with Ishigami.
- Romantic False Lead: Played with. Tsubame eventually comes to welcome Ishigami's attemps to court her in spite of her own insecurities. This causes Iino to become jealous of them and their date is what leads her to realize her own feelings for Ishigami.
- Rose-Haired Sweetie: She has pinkish hair with matching eyes, signifying her good and cheery nature.
- School Idol: Erika refers to her as "The Swan of the Third-Years", putting her on equal standing with the likes of Kaguya (which is high praise indeed, given that it's coming from Erika).
- Sempai/Kohai: Romantic variant with Ishigami has a crush on her. She also has a platonic relationship with Osaragi.
- Shadow Archetype:
- She serves as one to Kyoko Otomo, the girl Ishigami protected by keeping quiet about the fact that her boyfriend, Ogino, cheated on her, if the rumors about Tsubame's ex-boyfriend cheating on her are true. Tsubame was left scarred and has developed commitment issues, while Otomo has retained her happiness and smile.
- As Chapter 192 reveals, she also serves as an inverted one to Osaragi, both being one of the beautiful "Impossible Girls" in school, but unlike Osaragi, Tsubame is The Social Expert, who was able to withstand the jealousy of others and remained cheerful, while Osaragi became more introverted and cynical.
- Sibling Yin-Yang: Romantically, she's the opposite of her older brother. Both of them were confessed to with a heart during the Devoted Hearts Festival, but while he ended up Happily Married to the girl that confessed to him, she spent several months agonizing over how to avoid breaking Ishigami's heart because she didn't feel anything romantic towards him at all.
- So Beautiful, It's a Curse: The bonus page in Volume 21 revealed that due to Tsubame's natural beauty, she was the target of stalker, molester and has even entered an abusive relationship at one point where she was only in a relationship for a particular person for his social status.
- The Social Expert: Tsubame is chosen as both the vice-captain of the Cheer Team and the chairwoman of the Culture Festival Committee, because she is able to unite and lift the atmosphere when things get tense. She also advised Osaragi in middle school on how to deal with jealous girls who envy them for their looks and achievements, which earned her Osaragi's Undying Loyalty.
- Super Gullible: Tsubame is a bit superstitious, and often asks people for advice, generally believing everything they say. Shirogane's father gives her relationship advice during winter break, only to subvert the seriousness of his words by offering her a phony trinket that would help her, which she immediately buys, causing him to call her out on her gullibility. Its Played for Drama later on, as she heeded Atenbou's advice on having Pity Sex with Ishigami after rejecting his confession, leading to the incident that broke Iino's arm and further complicated a Love Triangle between the three. At the very end of Chapter 191, she still seek Papa Shirogane's advice when assuming that he still worked as fortune teller, hinting that she hadn't learned her lesson even after Maki in Chapter 162 indirectly pointed out her naivety in believing fortune tellers.
- The Tease: Tsubame teaching Ishigami how to use a cocktail shaker during the Christmas party with a Hands-On Approach was far more intimate than necessary. She also comes to his room very lightly dressed, sits suggestively and touches him a lot. She does this all deliberately, given the fact that she knew about his crush on her and was planning on having Pity Sex with him, to figure out how she feels about a romantic relationship with him.
- Tender Tears: The other members of the cheer squad note that she's a crybaby, as shown by her getting emotional over Ishigami getting second place in the relay race.
- Theme Naming: She's one of the many people named after Kaguya-hime's impossible tasks. In particular, she takes her name from Isonokami no Maro (Ishigami's namesake)'s task item, the swallow's cowry (tsubame no un da koyasugai).
- Unwitting Instigator of Doom: In Chapter 120, Tsubame tells Kaguya about heart-shaped gifts during the culture festival, which would grant the couple eternal love. She gifts Kaguya one of the heart trinkets they are selling as a service, but Kaguya loses it and it's found by Ishigami, who gives it to Iino, so she can put it in the lost & found box of the disciplinary committee. Ishigami giving Iino the trinket is part of the reason why Iino starts to view Ishigami in a different light, setting in motion the love triangle between her, Ishigami and Tsubame.
- We Used to Be Friends: Has a massive fight with Otomo, her kouhai from middle school, when she learns what really happened between her and Ishigami. To her, the Ishigami Otomo was describing didn't sound anything like the Ishigami she got to know personally, and was greatly saddened to see him be so hated by someone he wanted to help.
- Your Approval Fills Me with Shame: In chapter 192 when Tsubame reveals her plan to reveal at least some of truth of Ishigami's actions to Otomo to both Kaguya and Osaragi. Kaguya is shocked but approves, saying that even she couldn't come up with and do Tsubame's plan to Tsubame's displeasure.
Voiced by: Rina Honnizumi
Debut: Chapter 29 (Manga), Episode 13 (Anime)
The oldest member of the Tabletop Games Club with constantly changing nicknames.
- Adaptational Late Appearance: The anime cuts out her initial cameo from Chapter 29, so she doesn't appear until the adaptation of Chapter 57 at the beginning of Season 2.
- Book Dumb: She ranks near the very bottom of the senior class on exams, and her constantly decreasing nicknames suggest that she isn't much better at games. Chapter 202 reveals that she had already failed her senior year once, and she only managed to pass the second time around because her grandfather pulled some strings.
- But Not Too Foreign: As the principal's granddaughter, she's part-French.
- Chekhov's Gunman: Is first introduced as just another member of the Tabletop Games Club Fujiwara is part of, before later chapters revealed her to be the headmaster's granddaughter. She's also the one who allows Ishigami to befriend Shiranui.

- Graduate from the Story: Inverted. She didn't become relevant to the story until after she graduated from Shuchi'in.
- Known Only by Their Nickname: She's only referred to in-series by her ever-decreasing nicknames. It isn't until Chapter 202 that she's referred to by name (and even then, only her surname).
- Meaningful Rename: She used to be called "Terako", but she got demoted to "Gigako" after losing a game. The Volume 11 extras reveal that she was further demoted to "Megako".
- Nice Girl: All signs point to her being a much more benevolent person than her clubmates. Despite being a well-known streamer and e-sports player at this point in the story, she still makes time to play a few rounds with Ishigami simply because he's Fujiwara's friend.

Previous Student Council President
Debut: Chapter 121 (Manga), Episode 17 (Anime)
Shirogane's predecessor on the student council who had originally recruited him to be the General Affairs officer.
- Commissar Cap: He wears one as part of his student council uniform, which helps to give him an air of athourity.
- Early-Bird Cameo: He shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (he's the one all the way in the bottom right wearing a hat).
- Everyone Calls Him "Barkeep": Much like with his successor, he's only ever referred to by his title. Unlike with Shirogane though, his real name has yet to be revealed.
- Exotic Eye Designs: For whatever reason, his eyes are drawn without pupils.
- Nice Guy: While very little is seen about his personality (as he only appears in flashbacks), he was the first person in the school to reach out to Shirogane. He's also the one who established the practice of allowing normal students to come into the student council room to ask for help about their problems.
- Small Role, Big Impact: Shirogane never would have fallen in love with Kaguya if the previous student council president hadn't reached out to him and taken him to the lake on that fateful day, and Tsubasa never would have confessed to Kashiwagi if he hadn't established the practice of allowing students to seek advice from the student council.
- Student Council President: He held the role before Shirogane.
Voiced by: Taishi Murata (Japanese), Daman Mills (English)
Debut: Chapter 82 (Manga), Episode 17 (Anime)
An upperclassman and captain of the Cheer Team.
- Chick Magnet: Quite a few girls were pretty excited to see him crossdress in the sports festival.
- Ditzy Genius: He gets very good grades (being ranked 4th among the senior class), but he was dumb enough to try and jump a railing while wearing a long skirt, hurting his leg in the process.
- Early-Bird Cameo: He shows up early in the anime when Fujiwara is leading the student assembly in singing the school anthem during Episode 17 (He's the really tall one in the fifth row).
- The Faceless: As with the rest of the cheer team, in the sports festival arc. He only gets his face properly shown after Ishigami "opens his eyes" to the world again.
- Heroic BSoD: The break-up with Osaragi depresses him greatly, though he manages to cope with it by devoting his feelings to idols.
- Keet: He's the captain of the Cheer Team, it's to be expected.
- Like Brother and Sister: Ishigami assumed that he was in a relationship with Tsubame due to them having been friends for so long, though this is shot down when it's revealed that he's actually dating Osaragi.
- Lovable Jock: It isn't known if he's on any sports teams, but he is really into working out and is an all around Nice Guy.
- Nice Guy: Much like Tsubame, he accepts Ishigami easily despite the rumors surrounding him.
- One Head Taller: His girlfriend Osaragi is a little less than a head shorter than him. Of course, she is roughly two years his junior.
- On the Rebound: He immediately jumps into an otaku "relationship" with idols after Osaragi dumps him. Seeing as Osaragi is as beautiful as these idols, and in fact was an idol in the past, it's clear he is projecting.Kazeno: All the love I'd meant to give her, I've been pouring into these girls instead.
- Otaku: He ends up becoming an Idol otaku to cope with his depression over Osaragi breaking up with him.
- Wholesome Crossdresser: Not usually (as far as we know), but he is the one who came up with the idea for the Cheer Team to cross-dress during the sports festival.
Debut: Chapter 121 (Manga)
An upperclassman and also the president of the Mass Media Club, who works as the chief editor of the school newspaper.
- Ascended Extra: She only appeared twice in the main series before graduating, but she is a supporting character in We Want to Talk About Kaguya due to her being in the same club as Karen and Erika.
- Beleaguered Boss: As Karen and Erika's immediate superior in the Mass Media Club, she has to frequently keep both girls focused on their job while pulling them back to reality every time they're in Kaguya fangirling mode again. Which happens nearly all the time.
- The Confidant: Chapter 191 shows her listening to Tsubame's romantic issues. She can't really offer any kind of advice, though, since she has no experience in love. However, she was wise enough to warn against Atenbo's "when in doubt, have sex" suggestion and testifies that Karen and Erika both trust Ishigami. This doesn't help Tsubame's dilemma, and Asahi ends up telling her friend how annoying she is.
- Deadpan Snarker: Being directly in charge of two of the biggest and nuttiest Kaguya fanatics will turn you into one.
- Given Name Reveal: It took 70 chapters for her name to be revealed.
- Hypocrite: She scolds Karen and Erika for their favorable bias towards Shirogane in the election when they're supposed to be impartial as journalists. This is despite the fact that Kaguya had already arranged for her to support his reelection campaign.
- I Owe You My Life: After saving her from drowning in a flashback, Kaguya mentioned to Hayasaka that owing her a favor may prove useful in the future. We Want to Talk About Kaguya implies that she cashed in that favor to insure the Mass Media Club's support in Shirogane's reelection.
- It Runs in the Family: Her father is the chief of a big newspaper company.
- Meaningful Name: Her surname 'Asahi' (朝日) refers to the real life newspaper Asahi Shimbun, one of the five largest newspapers in Japan.
- Not So Above It All: Though she frequently chastises Karen and Erika for their borderline fanatical worship of Kaguya, she indirectly admits and considers herself "more than just a fangirl" for Kaguya, but refuses to give any more details to Karen and Erika beyond that out of a combination of embarrassment and not wanting to associate herself with their loonier fangirling. In her case, it's understandable: Kaguya did save her life once when no one else did.
- Only Sane Woman: Compared to Karen and Erika, she's the only named member of the Mass Media Club that actually focuses on doing her job. She also blocks all of their student council-centric articles from being published, since they write about as obsessively as they talk. Then again, she also appointed them as the new leaders of the Mass Media Club when she graduated.
- Prophetic Name: Her first name translates to "droplet" and her last name means "morning sun", alluding to how her falling into a swamp marked the start of Kaguya and Shirogane's romance.
- Secret-Keeper: As one of Shuchi'in High's most influential students, she is aware of Ko Ogino's true character.
- Small Role, Big Impact: In her first appearance in the main series she doesn't do anything other than fall into a swamp, but she has a major effect on the overall plot due to Kaguya rescuing her being the reason Shirogane fell in love in the first place.
Debut: Chapter 39 (Manga), Episode 8 (Anime)
The granddaughter of a high-ranking priest and president of Shuchi'in High's Occult Research Club.
- The Blind Leading the Blind: Atenbo is the one Tsubame listens to regarding her relationship with Ishigami, which ends up with Tsubame trying to initiate Pity Sex with him. Asahi criticizes her for the ill advice she gave, despite never being able to keep a longer lasting relationship, yet Atenbo still thinks her advice was sound.
- The Confidant: She is seen in Chapter 191, along with Asahi, listening to Tsubame's problems and advising her on how to proceed. Unfortunately, her advice doesn't help Tsubame at all.
- Early-Bird Cameo: She is first introduced in Chapter 39 as one of the club presidents who have the power to send any student and their family packing if they misbehave. However, her first real appearance is in Chapter 131, near the end of the Culture Festival arc.
- Ethical Slut: Based on the relationship advice she keeps giving to others, it's clear she is someone who thinks Sex Is Good and helps them sort their feelings out.
- Expy: Her name, occupation and art design are clearly based on "The Witch" (Yume Furusana), a character from Akasaka's previous manga ib: Instant Bullet.
- Eyes Always Shut: Her eyes have never been seen open, which fits her laid back and mischevious personality.
- Fortune Teller: She is seen during the last day of the culture festival, where she tells Kaguya's and Shirogane's fortunes. It's not clear if she really can see something or if she is just making good guesses.
- The Gadfly: Couples who ask her for their fortunes are getting teased so much that it borders on sexual harassment. For instance, when Kaguya and Shirogane come into her room, she assumes that they have a Secret Relationship and asks if they are using proper protection. She also frequently brings up people's libido and how they need to deal with it.
- Meaningful Name: Her given name is written in hiragana, giving a lot of ways to interpret it. "Yume" (夢) for instance can mean "dream".
- Nightmare Fetishist: She is the head of the Occult Research Club, so that was a given. Chapter 194 reveals that Kaguya received the recipe for the previous Valentine's Day Cubari Facaccimo "chocolate" from her.
- Secret-Keeper: As one of Shuchi'in High's most influential students, she is aware of Ko Ogino's true character.
- Small Role, Big Impact: Chapter 191 reveals that she was the one who told Tsubame to sleep with Ishigami, so she can be certain of her feelings for him. What she didn't expect was that Ishigami is an idealistic romantic who isn't just out for sex like that (and especially doesn't want to be pitied), which not only didn't help Tsubame, but made things worse between her and Ishigami, and indirectly led to Iino's arm being broken.
- Spell My Name with an "S": Due to the way Japanese long vowels can be romanized, her family name can be spelled Atenbō, Atenbou or Atenbo.
- Stalker Without a Crush: She somehow has access to information that shouldn't be publicly available, like Shirogane's weight at birth.
- Unwitting Instigator of Doom: She was the one who suggested that Tsubame offer Pity Sex to Ishigami during her Christmas party, and thus is indirectly responsible for Iino breaking her arm and complicating the love triangle between Ishigami, Iino, and Tsubame.
- You Need to Get Laid: Her relationship "advice" to others boils down to "have sex". It backfires horribly when she suggested the same to Tsubame to help her figure out her feelings for Ishigami. Ishigami isn't interested in sex without love, and Tsubame is too indecisive, so rejecting his confession yet still offering Pity Sex ended up hurting both Tsubame and Ishigami.
Shuchi'in Academy Middle School
Voiced by: Sayumi Suzushiro (Japanese), Heather Walker (English)
Played by: Amu Fukao (live-action movie)
Debut: Chapter 28 (Manga), Episode 6 (Anime)
Miyuki's younger sister. Treasurer of the Shuchi'in Academy Middle School Student Council.
- Adaptation Dye-Job: The live-action movie gave her black hair.
- Adaptation Relationship Overhaul: In the gender-bent AU chapters of the Official Doujin, she's notably much closer and less rebellious to Miyuki, who's her older sister there, even referring to her as "Nee-san".
- Annoying Younger Sibling: Kei is generally nice and polite, but is fairly rude towards her brother in comparison. Later revealed to be part of her rebel phase, since she feels like she's treated like a child whenever Shirogane interacts with her. This can also be seen in the way she calls her brother. She refers to Miyuki simply as "Onii", without -san, -chan, or any other suffix, showing that she acknowledges him as her brother but doesn't show him any additional respect beyond that.
- Big Brother Attraction: Defied. She deliberately avoids actions that would make her look like a brocon, and tends to complain at length about him given half a chance. This actually backfires in Moeha Fujiwara's case, as there's an noticeable undertone of pride in Kei's complaints that led her best friend to develop a Love Before First Sight on Miyuki.
- Big Brother Worship: Double Subverted. Kei greatly admires her older brother, but she deliberately hides it due to a combination of being in her rebel phase and not wanting people to think she has a brother complex. Even then, her pride for him still pours through in a Tsundere manner, enough so that Moeha falls in love with him based solely on her stories.
- Brutal Honesty: Which is why her brother's unwillingness to just say outright what he feels annoys her.
- Character Tics: She pretends to be stretching whenever she's secretly listening in on whatever her brother is doing.
- Chekhov's Gunman: Shirogane mentions her in the first chapter and she gets a few other acknowledgements early on, but she doesn't actually make a proper appearance until Chapter 39.
- Deadpan Snarker: When she's not outright insulting and arguing with her family, she comments on everything with a snide remark.Kei: (after Shirogane was gifted with his father's moon watch) Wow, it smells like old man in here.
- Don't Split Us Up: Her mother initially took custody of her when she abandoned their father due to her being more successful in her studies than her brother. However she soon chose to go back to her father and brother, and doesn't seem to have a high opinion of the woman in the present.
- Ensemble Dark Horse: In-universe. She's very popular among the fans of her father's YouTube streams and it always sees a spike in donations when she's on-screen.
- Even the Girls Want Her: It's mentioned that she is popular even among girls.
- Everyone Has Standards: The fact that she loves her brother does not mean that she has the patience for most of the stuff he does. However, whenever he is not near, she won't hesitate in talking about him with nothing but praises (just expressed in a Tsundere manner).
- Favors for the Sexy: Kei finds herself on the receiving end of this after her father becomes a successful YouTuber, with people throwing down 10000 yen in the super-chat every time she walks across the screen during one of his live streams.
- First-Name Basis: Insists on Kaguya calling her by her first name, which is something Kaguya usually never does, not even with Hayasaka.
- Gender-Blender Name: Just like her older brother.
- Good with Numbers: Implied, given that she is the treasurer for the middle school student council and in charge of her family's finances.
- Hairstyle Inertia: Flashbacks show her having the exact same hairstyle as a child, just shorter and with a hairband instead of a ribbon.
- Hereditary Hairstyle: The ribbon she wears is the only thing that separates her hairstyle from her mother's.
- Hot-Blooded: She is markedly snappy when it comes to her brother, venting her teenage angst upon him in her mother's absence.
- Interclass Friendship: With Moeha, and through her with Fujiwara. Later with Kaguya.
- It Runs in the Family: She has the same piercing glare as her brother and is just as good at hiding her shyness. The narrative also lampshades that her nervousness around Kaguya is a result of siblings having similar tastes. Chapter 52 reveals that she's just as thrifty as him, just as kind, and enjoys coffee.
- I Want My Beloved to Be Fashionable: Non-romantic example. In Chapter 119, Kei goes out of her way to make sure Shirogane doesn't embarrass her at her school festival, either by standing out in his high school uniform or by looking like a middle schooler with his terrible fashion sense. Seeing how her classmates are smitten and impressed by Shirogane when he shows up, she can't help but smile blissfully.
- Missing Mom: Her mother ran off about seven years before the story began.
- Nice Girl: Despite her rebellious streak towards her brother (she's an adolescent after all), she's just like him a very nice and kind-hearted person, and very selfless.
- One Degree of Separation: Is in the same year and friends with Fujiwara's younger sister Moeha. She sleeps over frequently at the Fujiwara household, and as a result is also close friends with Fujiwara herself.
- Perpetual Poverty: Due to her father being deep in debt, Kei constantly struggles with money and thinks in newspaper deliveries she has to do when she wants to buy something. This isn't likely to change in the near future, since her father cannot keep a job for long and both her and her brother are still in school. And while her father seems to have a promising future as a YouTube celebrity, if he really has built up a debt of over 500 million yen, he won't be able to pay off everything for a long time.
- The Quiet One: Her focus chapter states that she doesn't speak a lot.
- The Runaway: Subverted. She ran away from her mother to be with her father and brother.
- Schoolgirl Lesbian: Subverted. Her first appearance makes it look like she has a crush on Kaguya, but later chapters reveal her "crush" is just her admiring Kaguya as her personal idol and seeing her as a potential sister-in-law.
- School Idol: Just like her brother, Kei is admired by both the boys and girls in her school for her cute looks, her grades, and her innocent and just personality.
- Secret-Keeper: She finds out about her brother and Kaguya dating after overhearing them having a 5 1/2 hour phone call and then pumping him for all the juicy details.
- Sell-Out: Chapter 191 shows that she is seriously contemplating to sell herself out on the internet, seeing as her father gets 10,000 yen donations whenever she is passing by while he streams, with her admitting that she has done it on purpose several times already.
- Shipper on Deck: Kei is in fact curious of her brother's relationship with girls and would have been more than happy to ask about it in early chapters if it weren't for her measures to avoid appearing as a brocon. After both Kei and her father overheard Shirogane's 5-hour phone call with Kaguya, the father-daughter pair were willing to stay up all night just to listen to the lovebirds' conversation and further coerce the info from her brother during their breakfast.
- Shipper with an Agenda: While pairing her brother with Kaguya does seems genuine on her part, she also sees this as an opportunity to get closer with Kaguya as a sister-in-law.
- Siblings Wanted: Kaguya is jealous of Fujiwara's friendship with Kei, not knowing that she herself has the potential to be Kei's family, which is considerably more poignant than anything Fujiwara has with Kei, and even more, that Kei longs to be Kaguya's family too. She is in sore need of a stable female influence in her life, which her girl friends don't actually fulfill; cue Kaguya, a person she admires and wants in her life.
- Sibling Triangle: Subverted, because Kei isn't actually romantically interested in Kaguya, unlike her brother. However, both vie for Kaguya's affection and smugly tell the other sibling how close they are to Kaguya. Shirogane shocks Kei though, when she learns in Chapter 170 that the two have become a couple, and wants to learn all the details.
- So Proud of You: Beneath all her bitching and moaning regarding her brother lies a girl that has nothing but pride and love for him.
- Strong Family Resemblance: She looks like a female version of her brother, right down to the eyes. The resemblance is strong enough that Kaguya instinctively shows attraction to her despite her otherwise Single-Target Sexuality. Kei also has inherited her mother's looks, looking like a younger version of her.
- The gender-bent AU of the Official Doujin gives Kei a slightly different facial design to where she looks like a younger version of Miyuki, who's born as a girl there.
- Token Mini-Moe: She's a middle schooler and extremely adorable. Even Kaguya instinctively calls her cute as soon as she meets her.
- Too Much Alike: Kei, like her brother, is a prideful tsundere who Cannot Spit It Out. Thus she can't stand him always telling her what to do but she can't bring up the nerve to speak to him normally thus leading to their current frosty relationship.
- Tsundere: She's a (platonic) Harsh tsundere for her own brother. His nagging, pseudo-parental attitude gets on her nerves and she lashes out, to the point where the two of them haven't had a normal conversation in years. Despite that she does care about Miyuki (and is shown to be very proud of him), but carefully measures her interactions with him so it doesn't look like she has a brother complex.
- Unwanted Assistance: Her attempt to cover for Shirogane when Kaguya comes over to visit ends up making things look even worse than they would have originally, thanks to her tossing bags of trash and an erotic magazine into his study room.
- Vicious Cycle: The narration outright describes her relationship with Miyuki as one of these. His overprotective attitude makes her feel like he still sees her as a child, which leads to her acting mean and distant to him, which only makes him nag her more.
- What Beautiful Eyes!: Kaguya comments on the fact that she has the same eyes as her older brother upon meeting her for the first time, and nearly squees in excitement when she realizes the resemblance.
Voiced by: Ari Ozawa (Japanese), Kara Edwards (English)
Debut: Chapter 39 (Manga), Episode 8 (Anime)
Fujiwara's younger sister and the vice-president of the Shuchi'in Academy Middle School Student Council. She is close friends with Kei, who as a result frequently sleeps over at the Fujiwara household.
- Adaptation Dye-Job: Like her older sisters, her hair was changed from silver to pink in the anime.
- Commonality Connection: For all of Kaguya's comments about being unable to deal with her, they do have one major thing in common: their taste in men. They end up having a bonding experience over this commonality.
- Cute and Psycho: Her introductory chapter has her talking about wanting to torture Kei and eat Kaguya, all with a smile on her face.
- Foil: For Kaguya. Both of them are vice-president of their respective student councils, the youngest members of their families, and have a crush on Shirogane, but their personalities are opposites. Kaguya is scary on the outside and sweet on the inside, while Moeha is sweet on the outside and scary on the inside.
- Girlish Pigtails: As beffiting her Cute and Psycho personality
- Hopeless Suitor: She doesn't really have any chance getting together with Shirogane, given that he is solely focused on Kaguya by the time her crush is revealed.
- Love Before First Sight: She fell in love with Shirogane based solely on the information that Kei had given her.
Voiced by: Reina Ueda (Japanese), Brittany Lauda (English)
Debut: Chapter 55 (Manga) Episode 22 (Anime)
The girl that ruined Ishigami's reputation in middle school.
- Adaptational Jerkass: The anime adds an extra line to her rant against Ishigami where she yells at him for having the audacity to be enjoying himself at the sports festival, feeling he has no right to be happy after what she thinks he did. Oddly enough, in the second season's extra comic strips, they also reveal that Otomo is intentionally trying to make herself still hate him, but she can't completely do it since it's been so long and he looks good in drag.
- Adaptational Late Appearance: The anime cut out her cameo during Kaguya and Ishigami's first study session, so she isn't seen until Osaragi's Day in the Limelight when she gives an abridged version of Ishigami's backstory to the audience.
- Book Dumb: Turns out the reason she's not in Shuchi'in Academy High School is because she flunked the entrance exam.
- The Bus Came Back: She disappears from the plot after the events of the sports festival due to no longer attending the school, only to pop back up 100 chapters later during the "End of Secrets" arc.
- The Dreaded: To Ishigami. As soon as she shows up to his first sports festival, his mood deflates and becomes filled with fear.
- Early-Bird Cameo: She makes a couple of appearances in flashbacks before her proper physical appearance in the sports festival arc.
- Entertainingly Wrong: Due to her boyfriend's influence, she thought that Ishigami was harassing her and beat him up in jealousy, so she labeled Ishigami as a creepy pervert with an obsession with her.
- Given Name Reveal: Finally gets her name in Chapter 88.
- Good All Along: More of a revelation to the audience. All of her flashback scenes made it look like she randomly accused and led the pack on Ishigami for something he didn't do. In reality, she was defending her boyfriend from being punched, who she didn't know was a Bitch in Sheep's Clothing.
- Hidden Depths: One of the extra 4komas released with the second season's blu rays reveal that she actually attempted to forgive Ishigami for the incident in middle school as she didn't really want to keep staying mad at him forever, but hilariously enough, her petty jealousy at seeing him having fun with Tsubame made her forget about that.
- Innocently Insensitive: Upon reuniting with Ishigami, she wastes no time throwing insult after insult at him over what happened to them in middle school. She is completely unaware of all the circumstances, which Ishigami prefers.
- Locked Out of the Loop: Intentionally so. She's kept ignorant of her boyfriend's true colors even after she leaves school, for the sake of her happiness. The main point of Ishigami's martyrdom, and why he rescued her from her boyfriend at the cost of his own reputation, was so that she left the ordeal completely unharmed.
- Missed Him by That Much: She was just inches away from being retaliated against by Kaguya, who is dissuaded from doing so by Hayasaka because that would be a disservice for Ishigami's efforts to make Otomo happy. Instead, Kaguya reveals that while she'd keep her hands off Otomo, she had enacted retribution on Otomo's boyfriend for what he did the minute she learned the truth.
- Nice Girl: She's actually a rather sweet person and went out of her way to be friendly with Ishigami. The only problem is that she trusted her boyfriend more than him when she really shouldn't have. Not helping this is that Ishigami would prefer her hating him to her being hurt by the knowledge her boyfriend was cheating on her.
- The Not-Love Interest: Ishigami explicitly points out that he was not in love with her, though others like Osaragi don't seem to agree, especially since he fell in love with Tsubame, who is similar to Otomo in several ways.
- Shadow Archetype: Inverted with Tsubame. Tsubame is what Otomo could have become, if Ishigami hadn't stayed silent and she learned that her boyfriend cheated on her. Tsubame has Commitment Issues, while Otomo was left clueless and, outside of her breaking up with Ogino, has left Shuchi'in with only happy memories.
- Spell My Name with an "S": Due to the way Japanese long vowels can be romanized, her given name can be spelled Kyōko, Kyouko or Kyoko and her family is fan-romanized as Ootomo.
- We Used to Be Friends: It's revealed long after her appearance that she and Tsubame are old friends from middle school. Not so much anymore when Tsubame learns the truth behind the incident between her and Ishigami and comes to his defense, prompting a huge fight between them.
- With Friends Like These...: When Ishigami calls her an idiot, her friends comment it was very harsh from him, even if it's true. Yes, in front of her.

Played by: Fumiya Takahashi (live-action movie)
Debut: Chapter 85 (Manga) Episode 22 (Anime)
A former student of Shuchi'in Academy Middle School and Otomo's ex-boyfriend.
- Bitch in Sheep's Clothing: He presents himself as the kindhearted and upstanding student when in reality there is nothing good about him.
- Bright Is Not Good: He wears a white-colored Gakuran and is known to be superficial, but is definitely not a good guy in the slightest.
- Bus Crash: Downplayed. Kaguya tells Hayasaka that she ratted Ogino out to Shuchi'in's club presidents, fully aware that they would not approve and send him away. He was Put on a Bus, and while he's not dead, he's never going to come back.
- The Casanova: What he truly is deep down, as the only thing he cares about girls is to satisfy his own carnal desires.
- Hate Sink: He was cheating on Otomo, and tried to buy Ishigami's silence when he found out (by offering to let him sleep with her). Then he pulled a Wounded Gazelle Gambit, making it look like Ishigami was a Stalker with a Crush, and threatened to hurt Otomo (it's implied that he would have released revenge porn) if he revealed the truth. Those who know the truth about him rightfully find him despicable, and Kaguya and Shuchi'in's most influential students made sure that Ogino will never come back to Shuchi'in or Otomo again.
- Hidden Eyes: Curiously, his eyes are omitted completely in both the anime and the tankobon release of Chapter 88 of the manga. In the original release of the chapter, his eyes were fully drawn and detailed like mostly everyone else.
- Karma Houdini Warranty: Chapter 89 made it seem like Ogino was able to get away with turning Ishigami into a pariah until Chapter 90 revealed that Kaguya told the truth of the situation to the Shuchi'in VIPs that forced Ogino to transfer.
- Lack of Empathy: When Ishigami gives him an Armor-Piercing Question of what he thinks Otomo is, it's heavily implied that whatever Ogino said in response makes it clear that he doesn't care about his girlfriend's feelings in the slightest.
- Manipulative Bastard: After his attempts to buy Ishigami's silence caused the latter to attack him, he used his popularity and skill as a member of the drama club to frame Ishigami as a Stalker with a Crush.
- Psychotic Smirk: He gives a very scary one when he warns Ishigami of what he'll do to Otomo if the former were to reveal his Casanova nature.
- Pyrrhic Victory: Sure, he may have gotten off scott-free for his crimes and pushed all the blame onto Ishigami at first, but he'll spend the rest of his life being paranoid of Ishigami deciding to spill the beans or come back looking for revenge.
- Small Role, Big Impact: He only shows up in 3 chapters (and all those appearances are in flashbacks), but he's single-handedly responsible for turning Ishigami into the person he was at the beginning of the manga.
- Stepford Smiler: His kind smile is nothing more but a mask to hide how depraved he is.
- Villain with Good Publicity: He was one of the most popular students in middle school, meaning that with his word against Ishigami's, and his acting skills, it was obvious whose side most students and teachers would pick.

Played by: Masahiro Takashima (live-action movie)
Debut: Chapter 19 (Manga), Episode 4 (Anime)
The father of Miyuki and Kei. He is currently unemployed.
- Adaptation Dye-Job: He has black hair in the live-action movie.
- Amazingly Embarrassing Parents: He is a hilariously awkward man, and it quickly becomes apparent that he loves to deliberately embarrass his son. His first appearance has him yell to his son (loud enough that even Miyuki's sister could hear) that a girl is on the phone for him. He also loves to call himself Shirogane's Sugar Daddy.
- Aroused by Their Voice: When he becomes a YouTube streamer, multiple people in the chat are seen commenting on how awesome his voice is. Given who voices him in the anime, it's hardly a surprise.
- Badass Baritone: Despite appearing to be a pushover, it's shown time and time again that he is far smarter than he appears to be. He's also voiced by Takehito Koyasu, and in Chapter 191, he himself lampshades that his deep, low voice is quite appealing to others.
- But He Sounds Handsome: When he's trolling Kaguya into revealing her feelings for his son, he comments "his parents must have good genes" when she mentions his piercing glare.
- The Cobbler's Children Have No Shoes: He is easily the best person in the entire story when it comes to giving relationship advice, yet he's been estranged from his wife for over half a decade.
- The Comically Serious: Everything that comes out of his mouth is said with his same dead-serious face. His idea of small talk is asking Kaguya how far she has gotten with his son and offers to pretend to be her father-in-law at a parent-teacher conference without any hesitation.
- Contrived Coincidence: Several chapters before he's introduced, Kaguya imagines him exactly how he actually looks like. As she doesn't recognize him when she actually meets him, it's implied that she indeed did not know him, in spite of the crazy amount of tabs she keeps on Shirogane.
- Face of a Thug: To an even more extreme than his own son, not helped by the manga and anime artists drawing his face with harsh shadows all the time, nor by his voice actor being famous for voicing villains. That being said, he's harmless, and merely enjoys annoying his son while supporting him.
- Foot-Dragging Divorcee: He has no intention to divorce his wife, who has left him seven years ago.
- Fortune Teller: The New Game arc reveals that he sometimes works as a fortune teller in a shopping center, and he ends up giving some fairly good advice to Tsubame while on the job.
- The Gadfly: The first time he meets Kaguya, he tricks her into revealing her feelings for Shirogane without revealing that he is Shirogane's father. After she finds out, he openly admits that he did it just to mess with her (although he did have an ulterior motive).
- Good Parents: Zigzagged. He's no longer the breadwinner of the family (until he becomes a YouTuber) and hardly ever tries to deal with Kei's rebellious phase, but he is still being supportive of his son in his own way. His flashback in Chapter 91 sums it up with his words of advice to young Shirogane. Considering the nature of Shirogane, he took his father's advice to heart.Papa Shirogane: Miyuki, I'm a lousy person. I don't have the authority to boss you around. However, there is one thing that I want you to promise me. When the people he loves or the girl he loves is in trouble, a man will protect them, no matter what he takes. And he will face any challenge to do so. Miyuki, become that sort of man. That's all I ask of you.
- Hard Work Hardly Works: He busted his butt through college, managing to become a CEO and marry the most popular girl in campus, only for his company to go bankrupt, his wife to walk away from him soon afterwards, and become basically unhirable in his major forever.
- Hidden Depths: With him being a jobless father, who his children never take seriously, it's all the more surprising that he still has quite a few useful talents. Chapter 191 shows that he's a good artist, experienced at video editing and skilled at marketing to the point he was able to gain 50K subscribers on YouTube in a month.
- Hollywood Mid-Life Crisis: At times he goes Totally Radical and wears Age-Inappropriate Dress, causing great embarrassment on his son and daughter.
- Honest Advisor: While his fortune-telling is a bit of a scam, he is actually quite honest and serious when Tsubame asks for advice. Chapter 191 reveals that he decided to use his life experience to advise people on the internet.
- Inadvertent Entrance Cue: Most of his interactions with Kaguya start off this way.
- It's All My Fault: He admits to having been the inspiration for Miyuki's "motivational" posters, having used a similar method to win his wife back in the university. He was genuinely horrified with just how many of the posters Miyuki put around his study room and regretted not providing good moral support to his son.
- I Was Quite the Looker: One small flashback with him giving some good advice to a younger Shirogane showed he was quite dashing, looking like a taller version of his son; either the years caught up to him or losing his job and his wife running away took its toll on the man, maybe a combination of the two.
- Jack-of-All-Trades: He has a surprisingly long list of previous jobs of all calibers, and is frequently shown performing mundane part-time jobs from time to time. In spite of not being particularly noteworthy comparatively given his highly educated background, he eventually finds success as a YouTuber, as he is very charismatic and has enough job and life-related stories to fill an encyclopedia.
- Love Martyr: Despite his wife leaving him seven years ago, he refuses to divorce her because he still loves her. He knew she greatly valued social status when he tried, and succeeded, in courting her when they were in college, thus doing everything he could to secure them a nice upper class life, knowing full well things would, and did, go sour when he lost his business.
- Nice Guy: Despite appearances and his knack for being The Gadfly, Papa Shirogane surprisingly can be helpful to his family and other people when he situation calls for. Best shown when he's being supportive of his son's Relationship Upgrade with Kaguya or using said talent to become a YouTuber by giving advice. Apparently it becomes clear that this trait runs in the Shirogane family (minus the mother for obvious reasons).
- Not a Date: In Chapter 231, he accompanies Iino to buy gaming peripherals after school, which causes Onodera and Ishigami to suspect that she's going out with him.
- Not What It Looks Like: During the soran dance during Sports Day, Papa Shirogane taking Fujiwara's pictures initially seemed like a Dirty Old Man to Shirogane until the misunderstanding was cleared with Fujiwara's father actually asking him to photograph his daughter while he filmed her class's performance. Of course, not that Papa Shirogane ever tries to explain it to his son.
- Obfuscating Stupidity: He may present himself as a spacey, clueless man, but all it takes is a quick conversation to reveal that he's actually incredibly sharp and observant.
- Parental Substitute:
- For a chapter. Alongside Hayasaka's mom, he stands in for Kaguya's parents during her parent-teacher conference.
- He has also given life advice to Tsubame in his fortune teller part-time job.
- His actually good life advice is one of the reasons his streaming channel is so popular.
- Ends up becoming one to Iino after teaching her how to play video games. She even calls him Papa-san.
- Perpetual Poverty: He lives in a small apartment and sleeps in the living room, while his two children share a room. To alleviate the fact that he can't keep a job for long, his children work part-time jobs, they use coupons wherever they can and are very reserved when it comes to presents. After being tricked and losing his company by the Shinomiya group, he was left with a debt of over 500 million yen, not including interest. Even with a monthly income of over 1 million yen thanks to his YouTube activity, this isn't nearly enough to pay off his debt. By Chapter 197 however his channel is paying so well that he's willing to spend 200,000 yen a month on rent for a new apartment.
- Pushover Parents: A relationship chart of the Shirogane family in Volume 9 states he's afraid of Kei since she entered her rebellious phase and seems incapable of disciplining her, leaving the burden to his son.
- Riches to Rags: He used to be the CEO and at least partial owner of a company, but it was stolen from him by the Shinomiya family and he was left with a(n either figurative or literal) 500 million yen of debt. He hasn't held down a permanent job for a long time by the time the series starts.
- Sad Clown: Despite his tendency to crack up jokes and presenting himself as a jovial man to his children, deep down, he is a broken middle aged man who's troubled from his wife leaving the family and the failure to provide moral support to his son. Kaguya symphatizes with him in Chapter 208.
- Secret-Keeper: He was the third person after Karen and Hayasaka to find out about his son and Kaguya's Secret Relationship, having run into them during their first date.
- Secret Test of Character: He tested Kaguya's feelings for his Shirogane by pretending to be a random middle-aged man when they first met and trolling her into admitting what she likes about him. Given that his own wife turned out to be a Gold Digger who abandoned him when his company was stolen (by Kaguya's family, no less) he had a very good reason for wanting to make sure she didn't have any sinister intentions for his son.
- Shipper on Deck: He outright tells Kaguya that he's fine with her and Shirogane getting married while they're still in high school. After both Kei and the father overheard Shirogane's 5 1/2 phone call with Kaguya, the father-daughter pair were willing to stay up all night just to listen to the two lovebirds' conversation.
- Smarter Than You Look: While his appearance and lack of job could fool one into thinking he's an idiot, it's important to remember that his kids' smarts had to come from somewhere.
- He deduces that Kaguya has a crush on Shirogane and tricks her into admitting it within five minutes of meeting her.
- A later chapter reveals that he's a nationally certified career consultant.
- Chapter 191 reveals that he pulled a door-in-the-face technique on his children to make them accept his idea of a new job. He initially worked out a solid plan to become a Virtual YouTuber. After his children voiced their opposition, he then suggested to become a real streamer instead. When they gave their approval, he invested his free time into his YouTube channel, using his life experience in marketing and editing to create content on his channel with steadily rising subscriber numbers. The money he makes, thanks to monetizing his channel and streaming frequently, is well over 1 million yen in less than a month, shocking both of his children.
- Strong Family Resemblance: He looks like an older version of his son. The resemblance becomes even more noticeable in Chapter 91, which has a flashback to before he had wrinkles.
- Unnamed Parent: Despite being a recurring character, his name has never been mentioned.
- Virtual YouTuber: Subverted. He wanted to become one, but his children were against it. Instead, he decided to stream and create content on his YouTube channel as a real person. Though Miyuki suspects that he only suggested the celebrity idea so his kids would agree to the streaming.
- Wacky Parent, Serious Child: While he can be wise and reliable when he wants to be, Papa Shirogane has noticeable quirks such as being a picky eater, being incapable of holding a job, and frequently embarrassing his son with his awkwardness.
Debut: Chapter 83 (Manga), Episode 22 (Anime)
The estranged matriarch of the Shirogane family. She left about seven years before the story began.
- Education Mama: She always wanted smart children and always pushed them to excel. Part of the reason why her son is so obsessed with maintaining his role as the number one student is because he secretly hopes she'll come back for him.
- Foil: As a straight-up Education Mama who values her family on talents and successes alone, she is an opposite to Kaguya's deceased mother, Nayotake, who was otherwise a doting parent to her daughter. Hell, Shirogane's mother could easily fit in the Shinomiya family in terms of mannerism.
- Gold Digger: An Implied Trope to be one until Papa Shirogane's words in chapter 208 all but confirmed that she fell for him only for the success he had worked to obtain, as well as being a company president. When his company went bankrupt, she became desperate to coerce her children into becoming successful, and when Miyuki failed to meet her insane expectations, she took the more obviously brilliant Kei with her and abandoned him and his father for a rich younger man. This partially backfired on her because sooner than later Kei ran away from her to be with her brother and father, and she hasn't managed to get Papa Shirogane to sign the divorce, keeping her from marrying her next Meal Ticket.
- Hate Sink: She abandoned her husband and son when they failed to live up to her high standards, and was demanding enough towards Kei for her to run away from her back to her father. Even though she's been out of their lives for seven years now, a lot of Shirogane's present issues can be traced back to her, making it clear that the audience is supposed to hold her in contempt for her perfectionist attitude.
- Parental Favoritism: She favored Kei due to her being the better student, which is also why she initially took her when she walked out on her husband.
- Shadow Archetype: She represents who Kaguya would be if she did expect perfection from Shirogane, having left his dad and taken the more evidently intelligent of their children with her when his company went belly-up.
- Strong Family Resemblance: Flashbacks make it clear that she's where Kei gets most of her looks from.
- Badass Creed: The family has an especially ruthless motto that defines most of their relationships.
- Big, Screwed-Up Family: In addition to their corporate war with the Shijo family, the Shinomiya family members are pretty much troubled on the inside, especially due to their inhumane business practices, a Succession Crisis and other internal issues. It gets to the point that Kaguya has to seek Hayasaka's help in obtaining a compromising file of her brothers for her own defense.
- Feuding Families: The Shijo family came to exist because a portion of the Shinomiya family went into a disagreement with the main family branch due to their unethical business practice. The Shijo family had moved their business to overseas to prevent conflict with the Shinomiyas, but as Chapter 216 indicated, the corporate war has already happened in both of their businesses.
- Fiction 500: The Shinomiya zaibatsu is worth over one trillion dollars, and basically controls all of Japan.
- Love Is a Weakness: As the family creed states, Shinomiyas are expected to take advantage of others to get what they want, and must not love anyone.
- The Power of Hate: The Shinomiya family used violence to educate their children and associates, training them not to rely on others (instead, using other people as disposable tools) or showing emotions. The Shijo on the other hand use their long-standing hatred on Shinomiyas as a motivation to succeed.
- Predatory Business: As revealed in Chapter 209, the Shinomiya group cheated Papa Shirogane of his company, leaving him with a large amount of debt. The Shijo group were also none the different by slipping into the ranks of Shinomiya and secretly buying people and companies to slowly cripple the rival group from within.
- Succession Crisis: Its stated in the Volume 19 that Kaguya's olders brothers are fighting over the inheritance of Shinomiya family. With Oko's position as the heir being secured due to being the oldest son, Un'yo made his move to even try abducting Hayasaka to spill his older brother's secrets.
Voiced by: Eizou Tsuda
Debut: Chapter 44 (Manga), Episode 11 (Anime)The patriarch of the Shinomiya family, head of the mighty Shinomiya zaibatsu, and Kaguya's distant father.
- Abusive Parents: Violence is for him a legitimate way to educate his children and their associates, though Kaguya is so used to this, that she is fine with it and seems to employ similar methods to educate Ishigami.
- Corrupt Corporate Executive: Assuming that he is the direct head of the zaibatsu, then it's legit to say that he is also involved with the group's shady deals and other offscreen questionable acts.
- Hate Sink: His mistreatment of Kaguya is the source of many of her issues, and a good portion of the drama in the series, especially the Fireworks arc.
- Parental Neglect: Basically treats Kaguya like she doesn't exist and leaves her parenting to his servants, save for rare instances when he briefly acknowledges her before leaving.
- Small Role, Big Impact: His lack of parenting and affection for Kaguya is the source of her flaws and insecurities.
Debut: Chapter 79 (Manga), Episode 20 (Anime)Kaguya's late mother who died when she was a child.
- Deceased Parents Are the Best: She's the only member of Kaguya's immediate family who is depicted in a positive manner.
- Ill Girl: She's stated to have suffered from an unspecified heart disease.
- Meaningful Name: Her name translates to "Supple Bamboo", meaning that her daughter was metaphorically born from bamboo like her literary counterpart.
- Only One Name: She probably didn't share the Shinomiya surname given the fact that her daughter is stated to be an illegitimate child.
- Posthumous Character: A flashback to the sixth anniversary of her death shows Kaguya presumably in elementary school, indicating that she's been dead for a long time.
- Strong Family Resemblance: Assuming that she's the woman in Dr Tanuma's flashback, she looks just like her daughter.
- Theme Naming: When combining her name with her daughter, it gives the full title of the main character from The Tale Of The Bamboo Cutter, Nayotake no Kaguya-hime.
Debut: Chapter 162 (Manga)
The third son of the Shinomiya family and Kaguya's third elder brother.
- At Least I Admit It: Unlike the Faux Affably Evil Oko, he's at least aware that he is an asshole.
- Arc Villain: He's the primary antagonist of the class trip arc.
- Big Brother Mentor: Being the sibling closest in age to Kaguya who is in a similar position to him, Unyo was the one who taught Kaguya the way of the Shinomiya. However, he still acts like an Aloof Big Brother towards her, and he only mentored her because he thought he could make use of her eventually.
- Black Eyes of Evil: His eyes appear to be completely black with no visible sclera.
- Didn't See That Coming: His plan to get Hayasaka into his services was dependant on Kaguya giving him to her, which she would likely do after learning that Hayasaka has betrayed Kaguya from the beginning. What he didn't see coming was how much Kaguya loves Hayasaka and the fact that Kaguya has become a Defrosting Ice Queen, unlike him.
- Early-Bird Cameo: He's introduced in Chapter 162 during Kaguya's birthday and appears in 168 during Maki's flashback of her first meeting with Kaguya, but only gets named in Chapter 181.
- Even Evil Has Standards: What he hates most is treachery. In his eyes, both the Hayasaka and Shijo family are traitors, which is why he resents them.
- Evil Cannot Comprehend Good: He reveals Hayasaka's status as The Mole to Kaguya, believing that the betrayal would turn her cold. He's shocked and confused when Kaguya actually decides to forgive Hayasaka.
- Good Smoking, Evil Smoking: He's an unrepentant Jerkass, and he smokes cigarettes.
- Heel Realization: He acknowledges to himself that he's a "piece of shit" and doesn't seem particularly happy with how he turned out. He also seems to display some resentment towards Kaguya for turning out a better person despite growing up in a similar environment.
- Hope Crusher: Break Them by Talking seems to be one of his favorite ways to get what he wants, as can be seen when he tries this against Hayasaka and Kaguya to push them over the Despair Event Horizon.
- Ice King: Unyo is a cold and arrogant man, who belittles and mocks those he deems beneath him.
- I Gave My Word: If there is one thing that Kaguya respects about him, it's that he always keeps his promises. According to the Volume 19 omake, Kaguya's own principle to keep her promises is a form of pride for her elder brother.
- Jerkass: His first appearance has him ignore Kaguya greeting him. His second appearance shows him antagonizing Maki's father and calling the Shijo family a bunch of rats.
- Karma Houdini: He doesn't suffer any punishment for attempting to kidnap Hayasaka, save for a single punch to the face from Kaguya.
- Know When to Fold 'Em: His entire plan to get Hayasaka on his side (by force or otherwise) hinged on Kaguya turning on her once her betrayal was revealed. Once it becomes clear that Kaguya is going to forgive her, he gives up without a fight.
- Lack of Empathy: He couldn't care less about what his actions may do to the people he manipulates. During the class trip in Kyoto, he sends out his men to capture Hayasaka after learning that she intends to quit her job as Kaguya's personal servant. Since he can't just take her and would need Kaguya's permission, his plan involves breaking Kaguya and Hayasaka by revealing the truth about Hayasaka's role as The Mole of his elder brother, Oko.
- A Lady on Each Arm: Seen entertaining a pair of ladies during a flashback.
- A Lighter Shade of Black: According to Kaguya, he doesn't seem to have dirtied his hands as much as other Shinomiya members. While she doesn't think he's actually a good person, compared to his elder brothers he's not that bad, since he's self-aware enough to know he's an asshole, while Oko and their father believe themselves to be in the right.
- Manipulative Bastard: As Gan'an's third son from his second wife, Unyo is not in a very powerful position, but he makes up for it with threats and blackmail to get what he wants.
- Shadow Archetype: Unyo is the result of someone who embraces the Shinomiyas' upbringing to trust no one but themselves. If Kaguya hadn't defrosted due to the influence of Hayasaka, Shirogane and the rest of her friends, she probably would have turned out like Unyo, a bitter and lonely man. In addition like Kaguya, he is also a son from different mother than Gan'an's first wife.
- The Social Expert: Kaguya's expertise in diplomacy is something she learned from him.
- Theme Naming: The kanji for Unyo contains "hawk," indicating a bird theme for the Shinomiyas as Gan'an's name contains "grey geese."
- We Used to Be Friends: With Hayasaka's mother Nao (who used to be his valet) but their relationship broke down due to his eldest brother.
Debut: Chapter 184 (Manga)
The first son of the Shinomiya family and Kaguya's eldest brother.
- Bald of Evil: He has a completely shaved head and had his little sister monitored every day since she was seven.
- Faux Affably Evil: Everything that comes out of his mouth sounds like he is just worried about his little sister and very accomodating, but it's very obviously misogynistic and condescending in nature. Either that or he is so stuck in his beliefs that he actually thinks he is being nice to Kaguya and cannot understand that Kaguya wants Hayasaka to stay away from the Shinomiyas and not return to her side as her valet.
- Manipulative Bastard: Not much is known about him, but all Shinomiya members are brought up to be manipulative, and Kaguya considers Unyo to be better than her other two elder brothers. Unyo's relationship with Nao Hayasaka broke down because of Oko.
- The Patriarch: Oko is a man with old values stuck in a modern world. He is an imperious man who wants to dictate Kaguya's entire life, while claiming that it's for her own good.
- Right for the Wrong Reasons: His claims that marriage is a woman's greatest happiness and that Kaguya wouldn't be able to get married if she was better educated than her potential husband are meant to establish him as a Straw Misogynist, but he is technically correct as far as Kaguya and Shirogane are concerned. Kaguya's ultimate goal is to marry Shirogane and be a part of his family due to the Shinomiyas having basically starved her of affection her entire life, and part of the reason why Shirogane pushes himself to the point of exhaustion in studying is because he wants to prove that he can stand as Kaguya's equal.
- Sinister Surveillance: He's had Hayasaka report Kaguya's every move to him ever since the day the two were assigned to each other.
- Straw Misogynist: As Kaguya describes him, he's stuck in his belief that the world is ruled by men and women are tools for him to use. He expects Kaguya to be an obedient Shrinking Violet, and the only thing she is good for is to secure an alliance via marriage. If she overshadows potential marriage partners because she has a better education, she wouldn't be able to get married, and marriage is in his opinion a woman's greatest happiness. Therefore, he indirectly orders her to not apply for Stanford. However he doesn't expect her to remain chaste and doesn't mind if she wants to fool around a bit so it's downplayed in that one area.
Debut: Chapter 142 (Manga)
Maki's twin brother who doesn't attend Shuchi'in.
- The Ace: Smarter than all of the main cast, an expert soccer player to the point where he led his school to inter-high championships, and rich on top of all of that. Despite seeing very little of his actual life beyond Maki, Mikado is the whole package.
- Always Someone Better: He's the only one in all of Japan to have scored higher than Shirogane on the national mock exams. While Shirogane took first place on later exams, he's never managed to beat Mikado's original score.
- Annoying Younger Sibling: 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.
- Big Brother Instinct: Technically 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.
- Brilliant, but Lazy: He's a phenomenal sports player, but Mikado reveals that ever since that year he placed first in the mock exam he's been steadily sliding down the mock exam rankings. While the boy is smart, he explains that he only did so well because he had a reason to go all out, and he'd rather not do that all the time.
- Broken Ace: Due to his reputation as both The Ace and an heir to a major conglomerate, Mikado finds himself having a hard time fitting in once he transfers to Shuchi'in. His classmates find him completely unapproachable despite his best efforts.
- 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 than as any real expression of cuteness.
- Deadpan Snarker: He finds his sister's moodiness ridiculous and doesn't hesitate to tell her that.Mikado: Did you learn anything by coming to India?
Maki: I like Japan better than India.
Mikado: Is this the wisdom of my enlightened sister?
- Foil: Mikado is everything Shirogane is not: rich, the smartest boy in the country, and unconcerned about his public image. The reality of Mikado is that he's like any other kid, but his work ethic (which is to go all out when necessary but not all the time) heavily contrasts Shirogane's "must be perfect no matter what" initial hangups. There is also the fact that Shirogane desires to graduate at the top of a prestigious university while Mikado is content with attending a normal school and his parents reach a compromise with him in order to get him to transfer out. And on a more humorous note, they have opposite tastes when it comes to women's breasts.
- Forgotten First Meeting: He'd met Kaguya once when they were little at a Shinomiya/Shijo gathering, but Kaguya doesn't remember him at all.
- Heir Club for Men: Maki is the older twin, but Mikado is first in line to inherit the Shijo family business. It is also a Deconstruction, since he was pressured by the fact that a Shijo faction is trying to use him to further their goals, resulting in the transfer to Shuchi'in.
- Horrible Judge of Character: After being transferred to Shuchi'in, he tries to get along with the Class 3-A students. He rejected the idea of conversing with Kashiwagi as he finds her scary despite her being childhood friends with his sister and opted for Kaguya as the two met each others during an unnamed banquet. To his shock, Kaguya chews him out for calling her princess and tries to remind him of their positions (probably from the Feuding Families between the Shinomiya and Shijo).
- I Just Want to Be Normal: He decides to go to a completely normal school instead of a rich kids' academy like Shuchi'in, simply because he wanted to play ball with his friends.
- Likes Older Women: Implied. He's accused of prefering more mature women when he says that he likes breasts that sag just a little (although he vehemently denies it).
- New Transfer Student: In Chapter 211, he joins Kaguya and Shirogane's class at Shuchi'in in the third year.
- Nice Guy: Polite and modest, if a bit socially awkward. Shirogane manages to let go of his grudge against him within minutes of actually meeting the guy.
- "Not So Different" Remark:
- His sister pegs him as being cut from the same cloth as Shirogane in terms of personality, right down to them having the exact same pose when nervous. Even Mikado's academic achievements mirrors Shirogane's, with Shirogane pushing himself in order to impress Kaguya and Mikado doing the same to win his parent's approval to play soccer; it's no surprise, then, that they hit it off so well when they finally meet. Kaguya, however, is far more skeptical, believing that Mikado and Shirogane "aren't alike at all." When one considers their differing backgrounds, motivations, work ethics, and future goals, she may have a point.
- In Chapter 216, Maki stated that Mikado is currently being exploited by a faction of the Shijo family in light of their war against the Shinomiya (hence his timely transfer to Shuchi'in), which parallels Oko's grip on Kaguya's freedom.
- Obfuscating Stupidity: As Maki lampshaded, he may be looked like someone who has little care for his family business, but Mikado is fully aware that his transfer to Shuchi'in is because of the escalating war between the Shinomiya and Shijo groups. Furthermore, he's sharp enough at politics to find a workaround if he really wanted to, so he's clearly got some sort of ulterior motive in going along with the transfer, and even Maki doesn't know what that might be.
- One Degree of Separation: He's both Kaguya's distant relative and Shirogane's greatest academic rival. Shirogane seems to be aware of the connection, but sees no reason to talk about it.
- Red Baron: Around soccer players from other schools, Mikado has earned the fearsome appellation of... "Boy Fucker Mikado", given for crushing the dreams of aspiring soccer players when they have the misfortune of playing against him.
- 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.
- Strong Family Resemblance: He looks near identical to his father.
- 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".
- Unknown Rival: Shirogane considers him to be his greatest academic rival, yet he remains completely oblivious to this though it ultimately gets averted when the two finally meet. Mikado is not only extremely polite, but he finds Shirogane to be the more impressive of the two since Shirogane was able to score first in national mock exams multiple times in a row, compared to him only breaking a record once.

Played by: Jiro Sato (live-action movie)
Debut: Chapter 79 (Manga), Episode 20 (Anime)
One of the ten greatest doctors in the world. He is the physician for the Shinomiya family.
- The Casanova: He claims to have spent his teenage years sowing his wild oats, though this ended up backfiring when he found himself a father at the age of 17. Apparently, he's still pretty active, though he doesn't specify if it's with multiple women these days.
- The Comically Serious: When he tells Kaguya that she's suffering from love sickness as a diagnosis for her condition, he doesn't so much as crack a smile.
- Composite Character: In the live-action movie, he's also the narrator.
- Connected All Along: Chapter 147 reveals that he's Tsubasa's paternal grandfather.
- Generation Xerox: Both he and his son are doctors who had a child at 17. Considering the fact that Tsubasa is his grandson, it looks like that they're gonna go three for three on both accounts.
- Power of the God Hand: He's referred to as the God Hand due to his skill with performing bypass surgery on children.
- Reasonable Authority Figure: He's one of the greatest surgeons in the world and rubs shoulders with high-level dignitaries, but when he learns that Kaguya has fallen ill he cancels a party with the governor in order to immediately examine her.
- Shipper on Deck: He tells Kaguya that she should ask Shirogane out during his first appearance.
- Smart People Wear Glasses: As befitting a well respected surgeon.
- Teen Pregnancy: His son was born when he was 17 (exactly how old the mother was is not stated).
Debut: Chapter 111 (Manga)
The mother of Ai and loyal servant/employee of the Shinomiya family.
- Adaptational Early Appearance: A-1 Pictures released promotional artwork at the end of season two of her having lunch with her daughter during the sports festival. While she was mentioned during the sports festival in the manga (Ai is talking to her on the phone and upset over her having to cancel coming), she doesn't actually show up in person until Chapter 111 when the second years are having parent-teacher conferences.
- Foil: To her daughter. Much like her daughter with Kaguya, it's implied that she used to have a friendly relationship with, and spied on Unyo Shinomiya at the behest of Oko, though unlike Kaguya towards Ai, Unyo never forgave Nao.
- The Gadfly: Like mother, like daughter.
- Generation Xerox: She previously served as Unyo's valet when she was younger much like the relationship her daughter has with Kaguya, and that she also spied on him at the behest of Oko.
- Hired Help as Family: She appears to be something of a surrogate mother figure for Kaguya, given that her biological mother Nayotake died when she was very young. Her unseen husband is also specified to be Kaguya's godfather in their daughter's character profile.
- It Amused Me: She has Shirogane's father sit in on Kaguya's parent-teacher conference for this very reason.
- Parents as People: While she does love her daughter, her job makes it difficult to constantly be there for her.
- Unwitting Instigator of Doom: She's implied to be one of the reasons why Unyo turned out to be such a piece of shit, as the revelation of her spying on him left him a markedly distrustful and callous man.
- We Used to Be Friends: She used to be Unyo's valet and the two of them were very close (much like her daughter and Kaguya are currently). He never forgave her after finding out that she was spying on him.
Voiced by: Sally Amaki (Japanese), Morgan Garrett (English)
Debut: Chapter 20 (Manga), Episode 4 (Anime)
The student council vice-president of the French Shuchi'in Academy. She boasts a very sharp tongue and wit, which she puts to use as an acclaimed debater in France, winning two consecutive victories in the French Debate Meet.
- Break Them by Talking: Her specialty. She uses quick thinking and logic to deny her opponents' basic thinking, leaving them digging their own graves. Ends up being on receiving end of this from Kaguya, after attempting to do this to Shirogane.
- The Bus Came Back: After appearing in one very early chapter and never being seen nor mentioned again, she reappears 219 chapters later.
- Disease Bleach: In the anime, her hair is notably gray after being on the receiving end of Kaguya's verbal assault.
- The Dreaded: Is known as "Betsy the Wound-Licking Dagger." It is said that she will one day kill a man with her tongue.
- Eloquent in My Native Tongue: She started learning Japanese in between her first and second appearances, though her dialogue is very stilted. On the other hand, she's a skilled debater in her native French.
- Femme Fatale: Definitely appears like one. Points for actually being French as well.
- No-Sell: Her verbal assault upon Shirogane completely fails due to his inability to actually speak or understand French.
- Punch-Clock Villain: Arguably so, since her verbal assault upon Shirogane was ordered directly by the Japanese Shuchi'in Academy principal, as a Secret Test of Character for him.
- Red Eyes, Take Warning: Her eyes are blood-red, as befitting her ability to break people with her words alone.
- Student Council President: She's been elected to the position by the time of her second appearance.

A set of ramen connoisseurs, known for being the best ramen eaters in the entire metropolitan area. They go by their titles: San of Shibuya, J Suzuki of Koenji, the Immortal of Sugamo, and the Glutton Girl of Jinbocho.
- Ambiguously Related: The Immortal of Sugamo's last name is Tanuma, implying a relationship to Tsubasa.
- Big Eater: The Glutton Girl of Jinbocho's ramen eating style. Apparently she was once known as the "Ramen Vacuum-Cleaner". This brought her at odds with San of Shibuya, whose style consist more of refined preparations and eating.
- Brought to You by the Letter "S": When not working as a taxi driver, J Suzuki of Koenji wears a bandana with the letter J on it.
- Elite Four: Played for Laughs, as they are the four greatest ramen eaters in the city.
- Hero of Another Story: Their exploits are completely detached from Kaguya and Shirogane's Battle of Wits, and their paths only rarely cross with the rest of the cast.
- Minor Flaw, Major Breakup: As a testament to how seriously they all take ramen, San of Shibuya used to date the Glutton Girl of Jinbocho but broke up with her (despite admitting that he still loved her) because she ate ramen a different way.
- Only Known by Their Nickname: While all four of them have names, they are normally only referred to by their titles.

- Serious Business: Ramen, obviously.
- The Smurfette Principle: The Glutton Girl of Jinbocho is the only girl in the group.
