History Characters / KaguyaSamaLoveIsWarMiyukiShirogane

** He’s very knowledgeable about stars as he wanted to be an astronomer when he was younger before settling on reviving his father’s dead company.

* LoveMakesYouDumb: Played for laughs. Although he's a master of keeping his composure regarding Kaguya, when he tells her to [[spoiler:come with him to Stanford and she French-kisses him]], neither he nor Kaguya can think straight out of shock.

* LoveMakesYouDumb: Played for laughs. Albeit he's a master of keeping his composure regarding Kaguya, when he tells her to [[spoiler:come with him to Stanford and she French-kisses him]], neither he nor Kaguya can think straight out of shock.

* InnocentBlueEyes: PlayedWith; Shirogane's eyes are a bright shade of blue, and his unhealthy sleep schedule leaves him with a borderline-permanent DeathGlare with ExhaustedEyeBags to match. However, he is not ''entirely'' innocent given his fetishes and pervert habits, and is flat-out revealed to have a PornStash. Despite all this, he is genuinely benevolent at his core, and both Kaguya and Moeha find his eyes to be one of his most alluring features.

* DramaticallyMissingThePoint: He hears from Hayasaka that Kaguya is [[spoiler:back in IceQueen Mode]] because she's trying to be more honest and show him her weaknesses and bad sides on top of her good side in an effort to make their relationship more honest. When it's suggested that he needs to do the same and stop working himself to death, he instead doubles down on his unhealthy lifestyle, brushing off Kaguya's opinion because he feels she doesn't understand what it's like to be a normal person. This is ''exactly'' the attitude that alienated Kaguya from her peers years ago, and he only realizes this until Kaguya herself told him to his face.

** Hayasaka tries to tempt him into doing things to Kaguya when he comes to visit, pointing out that she wouldn't remember any of it due to her fever, the two of them would be left alone for three hours, and that the walls are soundproof. He manages to avoid giving in to temptation, though he says that it took every ounce of his willpower. Perhaps more importantly given the nature of their relationship, however, is that he ''also'' resisted the temptation to ask how she really felt about him or about any of her weaknesses.

* BatmanGambit: [[spoiler:In order to make sure that Fujiwara wouldn't interfere with his plan to confess to Kaguya, he makes up a whole PhantomThief plot with meaningless clues left behind, knowing that her love of riddles would keep her distracted until she solved it.]]

** Chapter 264 reveals that calling him "Miyuki-chan" was by far his biggest BerserkButton. This is because [[GenderBlenderName "Miyuki" is usually a female name]] (although the kanji used in his makes it a masculine one) and kids in elementary school always attached a feminine "-chan" to it whenever they wanted to make fun of him--that is until he put a hard stop to it by ''beating the crap out of anyone who called like that''. Not even his sister Kei, who usually has no trouble hurling insults at him, dares to push this particular button since the day she saw her normally calm brother flip out and beat another kid until he was kicking him on the ground. In the present day, he doesn't have much of a problem if a close-enough friend [[spoiler:or his girlfriend]] calls him "Miyuki-chan"[[spoiler:, except when Fujiwara does it because he knows she's just making fun of him.]]

* DramaticallyMissingThePoint: He hears from Hayasaka that Kaguya is [[spoiler:back in IceQueen Mode]] because she's trying to be more honest and show him her weaknesses and bad sides on top of her good side in an effort to make their relationship more honest. When it's suggested that he needs to do the same and stop working himself to death, he instead doubles down on his unhealthy lifestyle, brushing off Kaguya's opinion because he feels she doesn't understand what it's like to be a normal person. This is ''exactly'' the attitude that alienated Kaguya from her peers years ago.

* InsecureLoveInterest: He feels inferior to Kaguya, but wants to stand beside her as an equal. He studies desperately so that he can outdo her in at least one field but is very worried that she'll beat him one day. [[spoiler:It's also the very reason he wants to have her confess to him: if he confesses and she ends up rejecting him, he feels that he'll never end up closing the already wide gap between them. His self-esteem was already shot because of his mother abandoning him thus he feels that no one can love him for who he truly is.]]

* PornStash: Kei reveals that Shirogane has several porn sites bookmarked on his phone, which she uses as leverage to keep away from Kaguya.

* SingleGuySeeksMostPopularGirl: Shirogane, a working-class student and an outsider amongst the Shuchi'in students falls for Kaguya (the popular girl from the Shinomiya group) since the start of his freshman year. His constant scoring first place in tests and gets to be elected as the StudentCouncilPresident twice were all done in hopes of being able to stand on an equal footing with her.

* SuckinessIsPainful: His singing approaches BrownNote levels and has been compared to having sea cucumber guts shoved in your ears. That's not even getting into his rapping, which caused Fujiwara to collapse and start foaming at the mouth.

* WartsAndAll: After experiencing Kaguya's cold side, Shigorane exclaimed that while he was confused and worried about why she was acting cold, Shigorane would still love her no matter what mood she is, as he fell in love with the person whose ability was to show kindness without having to act kind.

* WhyDidItHaveToBeSnakes: Shirogane is extremely terrified of insects, enough to prefer going to the beach instead of the mountains (which is significant since he cannot swim). Of course, chapter 15 has him dealing with a cockroach.

** Hayasaka tries to tempt him into doing things to Kaguya when he comes to visit, pointing out that she wouldn't remember any of it due to her fever, the two of them would be left alone for three hours and that the walls are sound-proof. He manages to avoid giving into temptation, though he says that it took every ounce of his willpower. Perhaps more importantly given the nature of their relationship, however, is that he ''also'' resisted the temptation to ask how she really felt about him or about any of her weaknesses.
** [[spoiler: Even when they tried to have their first time, Shirogane stopz himself when he realizez something was bothering Kaguya, not wanting to continue if she is uneasy about it. They only resume when Kaguya gives her consent and kisses him.]]
* AccidentalTruth: In chapter 6, when Tsubasa mentions to Shirogane that the girls in his class made fun of him for not having a girlfriend. Shirogane then mentions that the girls probably all really liked him, and spouts out several hidden meanings behind their jeers and that they secretly all like him. It's all bullshit he made up on the spot to seem like an experienced ladies-man, but one of the girls he brings up says "That's hilarious" at Tsubasa, with the hidden meaning being "(I'm so glad he's free)". This particular girl turned out to be none other than [[EarlyBirdCameo Maki Shijo]], who ''did'' secretly like Tsubasa. She can be seen later that chapter when Tsubasa asks Kashiwagi out, and she's ''devastated''.

** In chapter 56, he doesn't notice any of Kaguya's attempts to make him squirm due to his excitement over watching the moon and causes her to squirm instead.
* AdaptationalSkill: Inverted. In the manga, he starts learning how to speak French after the embarrassment of being the only one at the exchange party who couldn't. The anime skipped over the chapter showing this, so he presumably never did so.

** The same can be applied to Fujiwara, at times, begging her to train him to become really good at an activity that normal people shouldn't have an issue with.

** A PlayedForLaughs version happens when Ishigami wants to brag after getting a decent number of Valentine Day chocolates in Chapter 195, only to see Shirogane has a pile of chocolates.

** He has an affinity for penguins, having a penguin plushie and often visiting the penguin exhibit at the local aquarium.

* ArmorPiercingQuestion: After watching Iino [[spoiler:silently watch Ishigami and Tsubame have fun together, he asks her point-blank if she loves him. Despite trying to deny otherwise, her tears afterwards make her true feelings clear.]]
* ArsonMurderAndJaywalking: Shirogane boasts that he has the top scores in the entire country, passed very high level tests, is a certified hazardous material engineer...and an appraiser of chickens. Even the illustrations show this, with various professional certificates drawn along a cartoon-style chicken.

* BeautifulAllAlong: Played with. Shirogane is already a fairly handsome young man, but most of the students find him intimidating due to his ExhaustedEyeBags giving him a constant DeathGlare. When he finally gets a good night's sleep after his term as president is over, the rest of the students suddenly find him a lot easier to approach, but Kaguya ends up ''less'' attracted to him due to him no longer conforming to her fetish, seeing as she associate his eyes to how he often looks at her and his true self being a hard worker.

* BeneathTheMask: Shirogane likes to put up the front that he's an intelligent, stoic and all around perfect person but as the series has shown that he's actually quite awkward, shy and unskilled beneath it all. [[spoiler:Chapter 147 shows that he hides a huge inferiority complex because of his mother's abandonment. Even his current popularity has only furthered his complex as he feels everyone around him only likes the ideal version of himself he presents instead of who he really is.]]

** Chapter 264 reveals that calling him "Miyuki-chan" was by far his biggest BerserkButton. This is because [[GenderBlenderName "Miyuki" is usually a female name]] (although the kanji used in his makes it a masculine one) and kids in elementary school always attached a feminine "-chan" to it whenever they wanted to make fun of him--that is, until he put a hard stop to it by ''beating the crap out of anyone who called like that''. Not even his sister Kei, who usually has no trouble hurling insults at him, dares to push this particular button since the day she saw her normally calm brother flip out and beat another kid until he was kicking him on the ground. In the present day, he doesn't have much of a problem if a close-enough friend [[spoiler:or his girlfriend]] calls him "Miyuki-chan"[[spoiler:, except when Fujiwara does it because he knows she's just making fun of him.]]

* {{Bishonen}}: Despite his somewhat sharp facial traits, and the bags under his eyes, he's actually a very attractive guy.

* BookSmart: He is not a [[TheAce multi-talented genius]] like his LoveInterest, Kaguya, but he makes up for his lack of prestige by his academic achievements, earning the best grades among the entire student body during exams, and is consistently placed as the top-scorer in the national mock exams--save for one time where he got beaten by Mikado Shijo. However, the series later acknowledge that he's probably not naturally that intelligent (being likely less bright than his younger sister Kei), and when he allows himself to slack off a little [[spoiler:after getting together with Kaguya]], his ranking drops to the 12th place.
* BrokenAce: On the outside, he seems to be an unflappable genius at every field, but in truth, he's hilariously incompetent at sports, rapping, dancing, languages, just about any other skill (other than playing all sorts of children's skill toys) not related to academics, and most of the time he's thrust into complicated situations, he survives by winging it while seeming calm. Deep down inside he is highly insecure and stressed out over his responsibilities and having to maintain his image.
* BrownNote: His rapping is enough to knock out Fujiwara and Hayasaka.
* CannotSpitItOut: Or rather, ''will not''. The entire premise revolves around Kaguya and Shirogane forcing the other to be the one to confess. [[spoiler: His reasoning being that someone of Kaguya's high class and talents would not be interested in someone who is not that talented. Figuring the only way to get together with Kaguya is for her to confess her feelings first.]]

** Shirogane always tried his hardest to keep up a good appearance and not show any weaknesses [[spoiler: because his mother abandoned him and believed Kaguya would not like the real him.]] But [[spoiler: starting a relationship with Kaguya]] and the aid of Fujiwara allows him to relax a bit to the point his grade drops a little by his own admission. This leads to him opening up about his weaknesses as the series goes on, letting his classroom know that he isn't good at balloon animals artwork and not mind their pity. During a batting cage outing, Shirogane, while hesitant, shows his friends that he isn't the best at batting, but tried to pay no mind to light teasing.

* ChickMagnet: Shirogane is very popular with girls. Sadly the girls he attracts are rather unstable.

* ComplexityAddiction: The entire premise of his relationship with Kaguya (and the reason why they are so good for each other) is because they both are covertly trying to force each other to confess their feelings first, when everybody, including the both of them, can tell they are a good couple. Even the tiniest gestures like sharing an umbrella needs to be a twelve-step scheme between the two of them, which all turns out to be for nought when people like Fujiwara break their plans by offering her own spare umbrella.

* CosmicMotifs: Shirogane is both a follower of astrology and dreamed of becoming an astronomer when he was younger, so he tends to have a close association with stars and uses them as profile pictures. This also ties into his relationship with the moon themed Kaguya, since the moon is always accompanied by stars.

* CripplingOverspecialization: If he wants to be able to compete in anything with Kaguya, he has to put all his efforts into just one field rather than [[MasterOfAll her well rounded portfolio]]. Doing that, he manages to score just a hair better than her on tests, but at the costs of being completely hopeless at anything else. Fujiwara helps him hide his shortcomings, which are numerous.
* CrouchingMoronHiddenBadass: An inversion. Shirogane is extremely intelligent and certainly doesn't lack physical ability. However, when he fails at something (IE-volleyball, singing, traditional Japanese folk dancing) he does so in ways that defy logic.

* {{Determinator}}: When he sets his mind to it, he'll stop at nothing to succeed. Case in point; at the start of his freshman year he was at the very bottom of the social food chain and only got in to Shuchi'in because he was on the wait list after nearly failing the entrance exams. Jump forward to the following year's culture festival, he's the two time StudentCouncilPresident, the number one-ranked student in his class, and has one of the most popular girls in the school hopelessly in love with him.
* DistractedByTheSexy: He suspended all student council activities before the second semester exams because being in the same room as Kaguya made it difficult for him to focus on studying.
* DitzyGenius: He's amazing at thinking logically and studying, yet he's also a complete inept when it comes to singing and sports.

* DontYouDarePityMe: Shirogane is a SupremeChef by his own right, but during a cooking contest between him, Ishigami and Kaguya, he wins because Fujiwara can tell that the dish he made was created by someone who didn't have much money, so she takes pity on him and lets him win. He is not happy about this at all.

* TheDreaded: For Fujiwara every time he wants to learn something in secret. Fujiwara absolutely dreads each instance because of two reasons: first, Shirogane is a grating and needy student who is equally terrible at handing constructive criticism; and second, he is so awfully bad at first that Fujiwara cannot bear not to help him. On top of that, because they do it in secret, she cannot reap the merits she deserves for his accomplishments, and even worse, third parties always think that it's ''effortless'' from him, when he received massive heaps of help from Fujiwara.
* DreadfulMusician: He's aware he's bad at singing, but not of how terrible it is. He think he's only a little tone-deaf, but in actuality his singing is enough to make Fujiwara scream for help. But as bad as his singing is, his ''rapping'' is even worse. How bad? Upon hearing it the first time, Kei called Fujiwara and begged her to choke the life out of her brother. He luckily improved with the help of Fujiwara.

* EveryoneCallsHimBarkeep: Most characters usually refer to him simply as "President". After his term as president ends it's revealed that Ishigami and Fujiwara are both on a FirstNameBasis with him, though Kaguya can't bring herself to call him anything other than "President" (in fact, the main reason why she asks him to run for a second term is so she has an excuse to avoid calling him by name). [[spoiler:The final chapter still has everyone calling him this despite him having already left for Stanford several months prior (something that Iino expresses minor annoyance over since ''she's'' the current president).]] This is averted in the English translation, where everyone is instead on a LastNameBasis with him.
* ExpositoryHairstyleChange: His hair is significantly messier in the present compared to flashbacks. It's bedhead that he doesn't have the time to fix in the morning since he gets so little sleep due to his increased work load.

* AFatherToHisMen: Or rather, to his fellow student council members. In chapter 20, the council successfully prepares a banquet meeting with Shuchi'in's sister school in Paris. Afterwards, Shirogane insists to the school principal that they be given more than just three days in advance, so he can avoid placing such a burden on his fellow council members.

** When Hayasaka [[TheGadfly tests out different disguises/identities with him]], she points out that he gets more flustered and aroused by scenarios that fulfill his control fantasies then overtly sexual or suggestive ones. Specifically maid and cat ears.

** When Shirogane realizes he hasn't really developed a relationship with Iino due to the many misunderstandings early on souring her good image of him, as well as his fear that she would hate him like she does Ishigami, he works to avert this. [[spoiler: This begin to change, if a little, when Iino revealed she knew about him dating Kaguya and the two talk at times about their love life.]]

* GentlemanAndAScholar: Parodied. His fellow students consider him an expert in a variety of subjects, unbeknownst that ''he's only good at studying''. What he is indeed is a tremendously lucky master of winging it with a poker face, so whatever counsel he dispenses sounds as expert opinion. However, he is truly a gentleman, which is one of his many virtues.
* GetAHoldOfYourselfMan: He does this twice for Ishigami, as shown in Chapter 89 and 90. [[spoiler:Flashbacks show Shirogane was the one that motivated Ishigami to come back to high school, by telling him that his efforts weren't in vain, that he was in the right and that the apology he is supposed to write should be a ShutUpHannibal. Shirogane gets Ishigami out of his slump again during the sports festival after Otomo appeared.]]

* HardWorkHardlyWorks: Averted or subverted, depending on how one looks at it. In Shirogane's own estimation, he has zero natural talent, and the only reason he holds the #1 spot in academia is because of the constant effort put into studying. It's been shown that he's from below average to downright atrocious when it comes to some mundane activities, including ones that any other individual wouldn't have had trouble performing reasonably well at without prior training (aside from, weirdly enough, playing with children's skill toys). It also takes tremendous amount of work, along with a skilled instructor, to bring his skills in those areas to about normal level. On the other hand, he is quick-witted and can come up with plans on the spot, holds multiple national certifications in different fields, manages to keep in balance his domestic routine, three part-time jobs and rather demanding studying sessions at the same time, eventually [[spoiler:gets accepted into extremely selective Stanford University ([[GradeSkipper at an accelerated rate at that]])]], and most importantly, '''always''' succeeds exponentially in self-improvement (becoming average at something may not sound extraordinary, but when you start below figurative "zero", it's a whole other story). All of that suggests he might be a very special human being.

** Steam starts coming off of his head [[spoiler:when he reads though the calendar of a stationary set that Kaguya gave him for Christmas and sees that it's filled with notes for all the days that she wants to spend with him now that they've had their RelationshipUpgrade.]]

* HormoneAddledTeenager: Downplayed, but like any guy his age, Shirogane is very interested but controls himself for the public. [[spoiler: When he begins to date Kaguya, he keeps the relationship slow, but when Chapter 216 occurs, Shirogane states that he would like to have his first time. Around Chapter 220, when doing the deed, Shirogane did manage to control himself when he realize Kaguya wasn't feeling comfortable. Comes Chapter 236, the two could not help but get in each other's bed the moment Kei left them alone.]]

** Whenever the exam results are out and he gets first again, beating Kaguya, he tries to play it off modestly (and so does Kaguya), but when alone he is actually shadow boxing out of happiness.

** During the Kyoto class trip, [[spoiler:he notices Hayasaka's QuietCryForHelp and resolves to help her, but his attempt to do so [[NiceJobBreakingItHero ends up making it worse]], as Kaguya's brother manages to track them down. When Kaguya later thanks him in Chapter 187 for helping Hayasaka, he tells her to ThinkNothingOfIt, with the narrator saying that it really ''was'' [[ExactWords "absolutely nothing"]]. The way he says it makes it look like he is just humble about it, when it really is just him making a BlaseBoast and [[SureLetsGoWithThat going along with what Kaguya thinks]].]]

* InferioritySuperiorityComplex: He works so hard as the student council president and the top student in his grade to hide his insecurity over his commoner heritage next to all the richer students. [[spoiler:Chapter 147 reveals that his mother leaving the family was the start of all this. Shirogane could feel his mother's interest was slipping with each failure until she finally left with Kei (who did well on her exams). To this day, he always hangs on to the hope that if he did well, she would return.]]

* LoveMakesYouDumb: Played for laughs. Albeit he's a master of keeping his composure regarding Kaguya, when he tells her to [[spoiler:come with him to Stanford and she French-kisses him]], neither him nor Kaguya can think straight out of shock.

* MoralityPet: Kaguya holds him in the highest regard, and she contains most of her ill-intended side so that she doesn't alienate him. By Shirogane's example, Kaguya has learned that she cannot possibly continue treating her peers as inferior if she expects to be at his side, and she is forever thankful towards him for forcing her to bring out the very best of herself where there was only a resentful, unfeeling husk before he showed up.

* NiceGuy: According to chapter 32, he's incapable of needlessly acting cold to people. Yes, he's extremely proud and can be slightly arrogant, but otherwise he's genuinely kind-hearted and friendly, cares for the student council and will do anything to help students that come for help. He's also a lot more honest with himself than Kaguya and thus more willing to throw his pride away to do what he knows is the right thing. Despite his massive ego, overwhelming pride, narrow-mindedness - e.g. his considerable difficulty seeing his own faults, much to Fujiwara's chagrin (who always ends up helping him), and correcting them, too, with him ultimately always willing, and always grateful towards her - and his somewhat cocky attitude at times, he's very selfless, virtuous and kind.
* NiceJobBreakingItHero: PlayedWith during the school trip to Kyoto. His efforts to help Hayasaka ended up amounting to nothing, if not making things harder for her and Kaguya. However he managed to prove to Hayasaka that there are people willing to help her without expecting any form of compensation, including him, Fujiwara, and her friends from school, which likely had an important positive effect in her bleak worldview.

** Invoked. In spite of Fujiwara's presence in the student council, which elicits considerable resentment on Kaguya due to Fujiwara's personability, good looks and nice figure, it's shown that [[SingleTargetSexuality Shirogane has eyes only for Kaguya]].
** Chapter 175 is all about Kaguya trying to get his attention. [[spoiler:While her first attempts are more mundane, she eventually sits on his lap, then embraces him and then kisses his cheek. It ''does'' disturb his focus, but he only reciprocates once he's done with work.]]

* OfficialCouple: [[spoiler:While the exact moment of their RelationshipUpgrade is somewhat hazy (there's arguments to be made for Chapters 136, 151, and 160), he and Kaguya are firmly a couple by the time they get back from winter break in their junior year.]]

* PerpetualFrowner: Due to his lack of sleep, nearsightedness and caffeine dependence, Shirogane always sports intimidating TsurimeEyes. Should he get a good night's sleep, they turn into TaremeEyes, making him seem considerably more accessible. However, Kaguya likes him better when he has a glare and bags under his eyes.

* PornStash: Kei reveals that Shirogane has several porn sites bookmarked on his phone.
* ThePowerOfLove: Shirogane was originally a nobody, just some poor kid who was lucky enough to be accepted into a prestigious high school because he was on the wait list. Then he fell in love with Kaguya... Jump forward a year a half, he's the most popular guy in school, the two-time elected StudentCouncilPresident, the second highest scoring student in the entire country, [[spoiler:and set to graduate a year early so he can attend Stanford University.]]
* PrecociousCrush: Downplayed. During a question about the characters' first loves in a Q&A, the author mentions how he had feeling for a female tutor (specified post-series to be Fujiwara's older sister Toyomi), though the author specifies that it wasn't serious enough to qualify as a crush.

* SelfServingMemory: Inverted with how he acted during the Fireworks Arc. For Kaguya, is was one of the most romantic moments of her life. For him?

* SenpaiKohai: He deliberately tries to develop this sort of relationship with Iino after realizing that they're TheFriendsWhoNeverHang. The chapters that focus on them are even called "Senpai-kun and Kohai-chan".

* SingleGuySeeksMostPopularGirl: Shirogane, a working class student and an outsider amongst the Shuchi'in students falls for Kaguya (the popular girl from the Shinomiya group) since the start of his freshman year. Him constantly scoring the first place in tests and gets to be elected as the StudentCouncilPresident twice were all done in hopes of being able to stand on an equal footing with her.

** Beyond his romantic intentions towards her, Shirogane considers Kaguya one of the very best people he's ever met, and derives a significant amount of pride from the mere fact that she's his partner and his friend.

* StudentCouncilPresident: At least of their second year at Shuchi'in. He takes the job so seriously that he refused to take his gakuran and aguilette off until the end of his term because he wanted to do his job with pride and respect.

* SupremeChef: Cooking is one of the few skills that Shirogane is good at (although Fujiwara assumes that it's because he probably has years of practice). Fujiwara has nothing but praise for his cooking after she eats some of his lunch in Chapter 5, and she is brought to tears when she eats his fried rice in Chapter 96... [[SubvertedTrope but not because of it tasting better than Ishigami's rice actually]], but rather because he made a dish just as good with cheaper ingredients and she takes pity on his financial situation. He was far from pleased about Fujiwara's reasoning.
* TakeAThirdOption: Chapter 189 has him being confronted by Kaguya and Fujiwara if he ships Ishigami with Tsubame or Iino. What does Shirogane do? [[spoiler:He [[ScrewThisImOuttaHere runs away]], not wanting to choose.]]
* TeenGenius: Reportedly has the second highest test scores in all of Japan, and is certified in many professional fields. However, his profile in volume 1 notes that calling him a natural genius wouldn't be proper due to his intellect being a result of obsessive studying rather than inherent talent.

* ThereIsOnlyOneBed: Invoked. Due to his family's monetary constraints, he shares a room and a bed with his sister that is separated by a curtain.
* TookALevelInKindness: As the series goes on, we start to see more and more of Shirogane's personality and less of his ego. As such he comes off as much kinder and relatable compared to the start of the series.

** He is initially harsh towards [[spoiler:Mikado]] when they first meet, only to start blushing in embarrassment and drop his hostility the instant they say that they admire him.

* TheUnfavourite: [[spoiler:His mother was a relentless EducationMama who ended up favoring Kei due to her doing better on exams, even taking her with her when she abandoned their father. He does not appear to have any form of resentment for his sister, though he clearly has a very low opinion of his mother.]]
* UnknownRival: [[SubvertedTrope Subverted]]. Shirogane assumes he's this to Mikado, the one student to beat him in their first mock exams that hasn't bothered to take another since. [[spoiler:In reality, Mikado only tried hard on the one exam so that his parents would approve of him playing soccer, and admires Shirogane as the better student because he's able to get great scores on every exam he takes. Because of this, the two become friends.]]

* UnwittingInstigatorOfDoom: He's the one who convinced Tsubasa Tanuma to ask Nagisa Kashiwagi out. This has left Maki Shijo, who loved him, to distress over her unrequited love for the entire story.

** Tsubasa initially comes to him for love advice for this very reason. The ''We Want To Talk About Kaguya'' SpinOff shows this came to happen due to a series of OutOfContextEavesdropping. First, he overheard Karen and Erika talking about how the student council will give you love advice if you ask for it. Then he saw Fujiwara returning a lunchbox to Shirogane as she thanked him for making her lunch. Then he learns about the rumors treating Kaguya and Shirogane as the OfficialCouple of the school. Finally, he overhears ThoseTwoGuys that hang out with Shirogane talking about how he "already moved onto another one" and how "he never stays with one for long" -- they're talking about how Shirogane [[WhyDoYouKeepChangingJobs keeps changing part-time jobs]], but Tsubasa assumes [[TheCasanova he plays the field]]. Heck, even Shirogane's bad advice to Tsubasa about asking Kashiwagi out with a WallPinOfLove ended up working out perfectly, which likely only further cemented his image of Shirogane as an love expert.

* WartsAndAll: After experiencing Kaguya's cold side, Shigorane exclaimed that while he was confused and worried about why she was acting cold, Shigorane would still love her no matter what mood she is, cause he fell in love with the person whose ability was to show kindness without having to act kind.
* WeirdnessMagnet: It was stated that early on that the girls that he attracts are mentally unstable. Considering the three girls that are attracted to him are [[MoodSwinger Kaguya]], [[MsImagination Karen]] and [[spoiler:[[CuteAndPsycho Moeha]]]], this is pretty accurate.

* WhatBeautifulEyes: Kaguya [[spoiler:and Moeha]] list his piercing gaze as one of his most attractive physical features (the other being his nose). When Shirogane finally gets a good night's rest, the student body finds his proper eyes to be very attractive as well bar Ishigami, who finds it creepy, and Kaguya, for the above reason.
* WhatTheHellHero: PlayedForLaughs in Chapter 176. Shirogane's attempt of a MotivationalLie to cheer up Ishigami, who is practicing volleyball, backfires and gets him a scolding from Fujiwara, who was standing next to him, because he tried to make himself look better than he really was and conveniently left out that he had her help.

* WorfHadTheFlu: [[spoiler:His grades dropped significantly to the 12th place in the final test for his second year. While Kashiwagi and Kaguya (initially) thought of this as a case of him losing his interest for her, its actually a combination of him relaxing his studies a little bit (taking Kaguya's words in Chapter 151 to heart) while preparing for his entrance to Stanford and taking Ishigami's duties as the treasurer]].

* YouAreWorthHell: Fulfilling his claim back in Chapter 56, [[spoiler: Shirogane spends the majority of the final arc fending off against the Shinomiya's family and rescuing Kaguya. At the end of Chapter 261, Shirogane vows that he doesn't care if it takes hundreds of years or she was moved somewhere far away, he will make sure they are togother again.]]

** [[spoiler: Even when they tried to have their first time, Shirogane stop himself when he realize something was bothering Kaguya, not wanting to continue if she is unease. They only resume when Kaguya gives her consent and kisses him.]]

** In chapter 56, he doesn't notice any of Kaguya's attempts to squirm due to his excitement over watching the moon and causes her to squirm instead.

* AffectionateNickname: Even after his first term ended and [[spoiler:no longer running for president since graduating,]] nearly everyone still refers to him as president either as a habit or a sort of nickname. [[spoiler:Even his girlfriend, Kaguya, still refers to him as president.]]

** The same can be applied to Fujiwara, at time, begging her to train him to become really good at activity that normal people shouldn't have an issue.

* CannotSpitItOut: Or rather, ''will not''. The entire premise revolves around Kaguya and Shirogane forcing the other to be the one to confess. [[spoiler: His reasoning being that someone of Kaguya high class and talents would not be interested in someone who is not that talented. Figuring the only way to get together with Kaguya is for her to confess her feelings first.]]

** Shirogane always tried his hardest to keep up a good appearance and not showing any weakness [[spoiler: because his mother abandoned him and believed Kaguya would not like the real him.]] But [[spoiler: starting a relationship with Kaguya]] and the aid of Fujiwara allows him to relax a bit to the point his grade drops a little by his own admission. Even opening up about his weaknesses as the series goes on, letting his classroom know that he isn't good at balloon animals artwork and not mind their pity. During a batting cage outing, Shirogane, while hesitant, shows his friends that he isn't the best at batting, but tried to pay no mind to light teasing.

** Even though it was Hell for Fujiwara, Shirogane begins to learn basic things much quicker and less painful by taking what Fujiwara taught him to good use. He is able to pick up ballroom dancing and baseball batting form faster than it would take three days to volleyball when he started.

* CluelessChickMagnet: Despite his SingleTargetSexuality to Kaguya, he has yet to realize that Karen and [[spoiler:Moeha]] also have a thing for him. [[spoiler:Chapter 194 has Iino revealing that he has a few admirers who would've been happy to give him Valentine chocolates, but they gave up after seeing him with Kaguya.]]

** He thought about to use his presidential powers to prevent Kaguya from going to receive a love confession from another boy, especially when she suggests she might actually accept it. There are also moments where he is jealous of Ishigami spending time with Kaguya and being treated differently.

* EarnYourHappyEnding: [[spoiler: If Chapter 276 isn't a dream, Shirogane grow up to restart his father's company and manages to marry Kaguya, with her adopting his last name.]]

* HereWeGoAgain: [[spoiler:After everyone graduated, a new love is war game has set, with Shirogane wanting to be a big-time success to the Shinomiya before proposing to Kaguya with the latter wanting him to propose as soon as possible.]]

* HormoneAddledTeenager: Downplayed, but like any guy his age, Shirogane is very interested but controls himself for the public. [[spoiler: When he begins to date Kaguya, he keeps the relationship slow, but when Chapter 216 occurs, Shirogane state he would like to have his first time. Around Chapter 220, when doing the deed, Shirogane did manage to control himself when he realize Kaguya wasn't feeling comfortable. Comes Chapter 236, the two could not help but get in each other's bed the moment Kei left them alone.]]

* InterclassFriendship: Any friendship he has with the rest of the Student Council is this by default since he's one of the few working-class students attending a school for the wealthy and famous. {{Downplayed|Trope}} [[spoiler:since his family was used to be wealthy, but fallen onto hard times from the actions of the Shinomiya Group, leaving Papa Shirogane's company bankrupt and having a crippling debt to pay off.]] Furthermore, this trope might not apply to him much longer [[spoiler:once he goes off to study Business Management at Stanford University, and aiming to take back his father's company]].

* NiceJobBreakingItHero: PlayedWith during the school trip to Kyoto. His efforts to help Hayasaka ended up amounting to nothing, if not making things harder for her and Kaguya. However he managed to prove to Hayasaka that there are people willing to help her without expecting a compensation, including him, Fujiwara, and her friends from school, which likely had an important positive effect in her bleak worldview.

* ThePerfectionist: He is obsessed with maintaining his perfect student council president image. He takes studying very seriously, and any shortcomings he may have ([[CripplingOverspecialization of which there are a lot)]] are painstakingly rooted out and overcome. Part of this effort is motivated by his desire to stand as [[TheAce Kaguya's]] equal [[InsecureLoveInterest and prove that he's good enough for her]]. [[spoiler:The rest is because he was abandoned by his mother as a child when he didn't meet her insanely high standards.]]

** His attempt at the Soran dance was so atrocious that Fujiwara compared it to someone being painful excorcised to the beat of a drum.

* SupremeChef: Cooking is one of the few skills that Shirogane is good at (although Fujiwara assumes that it's because he probably has years of practice). Fujiwara has nothing but praise for his cooking after she eats some of his lunch in Chapter 5, and she is brought to tears when she eats his fried rice in Chapter 96... [[SubvertedTrope but not because of it tasting better than Ishigami's rice actually]], but rather because he made a dish just as good with cheaper ingredients and she takes pity on his financial situation.

* WartsAndAll: After experiencing Kaguya's cold side, Shigorane exclaimed that while he was confused and worried about why she was acting cold, Shigorane would still love her no matter what mood she is, cause he fell in love with the person whose ability to show kindness without having to act kind.

* YouAreBetterThanYouThinkYouAre: Shirogane received this from Dr. Tanuma and Kaguya

** Kaguya, after learning about his past from Papa Shirogane and overhearing Dr. Tanuma, [[spoiler: assure Shirogane that she loves him whether at his weakest or strongest. That she feels afraid at times too and can take breaks together.]]
* YouAreWorthHell: Fulfilling his claim back in Chapter 56, [[spoiler: Shirogane spends the majority of the final arc fending off against the Shinomiya's family and rescuing Kaguya. At the end of Chapter 261, Shirogane vow that he doesn't care if it takes hundreds of years or she was moved somewhere far away, he will make sure they are togther again.]]

* ADateWithRosiePalms: Kei reveals that Shirogane has several porn sites bookmarked on his phone. What he uses them for is quite obvious.

* TheyDo: [[spoiler: If ''Manga/OshiNoKo'' and Chapter 276 are anything to go by, Shirogane and Kaguya ended up getting married.]]

* AboveTheInfluence: Hayasaka tries to tempt him into doing things to Kaguya when he comes to visit, pointing out that she wouldn't remember any of it due to her fever, the two of them would be left alone for three hours and that the walls are sound-proof. He manages to avoid giving into temptation, though he says that it took every ounce of his willpower. Perhaps more importantly given the nature of their relationship, however, is that he ''also'' resisted the temptation to ask how she really felt about him or about any of her weaknesses.

* AdaptationalSkill: Inverted. In the manga, he starts learning how to speak French after the embarassment of being the only one at the exchange party who couldn't. The anime skipped over the chapter showing this, so he presumably never did so.

* SempaiKohai: He deliberately tries to develop this sort of relationship with Iino after realizing that they're TheFriendsWhoNeverHang. The chapters that focus on them are even called "Senpai-kun and Kohai-chan".

* SamaritanRelationshipStarter: He initially fell in love with Kaguya [[spoiler:after seeing her rescue the Mass Media club president from drowning in beginning of their freshman year.]]

* EveryoneCallsHimBarkeep: Most characters usually refer to him simply as "President". After his term as president ends it's revealed that Ishigami and Fujiwara are both on a FirstNameBasis with him, though Kaguya can't bring herself to call him anything other than "President" (in fact, the main reason why she asks him to run for a second term is so she has an excuse to avoid calling him by name). This is averted in the English translation, where everyone is instead on a LastNameBasis with him.

* HappilyMarried: According to Manga/OshiNoKo and Chapter 276 [[spoiler:sometime in the near future, Shirogane and Kaguya get married with the latter adopting his surname. And based on what’s shown, they seem to be happy together.]]

* HighSchoolSweethearts: Taking into what Manga/OshiNoKo and Chapter 276 shown [[spoiler:Shirogane and Kaguya remained together even after high school and married.]]

* HighSchoolSweetheart: Taking into what Manga/OshiNoKo and Chapter 276 shown [[spoiler:Shirogane and Kaguya remained together even after high school and married.]]

* BeautifulAllAlong: Played with. Shirogane is already a fairly handsome young man, but most of the students find him intimidating due to his ExhaustedEyeBags giving him a constant DeathGlare. When he finally gets a good night's sleep after his term as president is over, the rest of the students suddenly find him a lot easier to approach, but Kaguya ends up ''less'' attracted to him due to him no longer conforming to her fetish. Seeing as she associate his eyes to how he often looks and his true self being a hark worker.

** When Hayasaka [[TheGadfly tests out different disguises/identities with him]], she points out that he gets more flustered and aroused by scenarios that fulfill his control fantasies then overtly sexual or suggestive ones.

* CoordinatedClothes: After [[spoiler:becoming a couple with Kaguya, he got himself and her a special crescent moon necklace for her birthday to ''share their time together.'']]

** Dr. Tanuma and his nurse [[spoiler: comfort Shirogane after he opens up about why he works so hard to keep a perfect image and tells him that he’s fine the way he is, but he needs to take breaks or otherwise it might damage him
