An obvious work in progress, but long overdue. Could use some work on the characters from the sequels.
For characters who are mentioned/related but don't actually make an appearance in the games, please see Characters in Overflow Universe.
Voiced by: Daisuke Hirakawa (under the name "Tatsuya Hirai" in the games)
- Above the Influence: He's still a horny teenager, but he can control his carnal urges on occasion. In one example, Otome will proposition use of the break-room during the school festival. If Makoto has been pursuing Kotonoha exclusively up to that point, he'll turn Otome down (albeit rather curtly). In another example, Kotonoha will proposition sex to Makoto on the school roof. In this case, it's up to the player to turn her down. Should the player choose no, Makoto will explain himself by simply stating that he wasn't feeling like it. It's not exactly the kindest or noblest of reasons, but it's still a stark contrast to the horny Jerkass he is in the anime.
- Adaptational Villainy: He's not exactly a saint in the original visual novel even if you try to play him as nicely as possible, but in the anime, he's a lecherous, self-absorbed, debauched asshole. The Cross Days manga takes this even further, turning him into a sexual predator.
- Affectionate Nickname: Will be called "Makoto-kun" by Kotonoha in School Days, and "Mako-chan" by Setsuna in Summer Days/Shiny Days, after he starts dating either girl.
- Alas, Poor Yorick: The final scene of the anime, with Kotonoha sailing off into the sunset with Makoto's head.
- Ambiguous Disorder: His bizarre lack of expressiveness, complete inability to control his sexual urges, and severely limited understanding of the thoughts and feelings of others suggests that there's something wrong with him, though what exactly is never discussed. At his absolute worst, he verges into The Sociopath territory.
- Anything That Moves: Has officially qualified for this trope as of the Cross Days sequel in the game series: pretty girls his age? Check. Their beautiful young mothers? Check. Their thirteen-year-old sisters? Double Check. Adorable BOYS his age who are just as beautiful (if not more so) than his girlfriend(s)? Triple Check. Thank goodness he hasn't yet shown sexual interest in farm animals or senior citizens.
- Asshole Victim: Come on, you know you were celebrating when he got killed in Episode 12.
- The Atoner: Makoto tries to be this at the end of the manga, only to be way too late due to him being hospitalized.
- He also tries this in the anime. After realizing the damage he has done to Kotonoha, he commits to her fully in order to make up for his mistakes. Unfortunately, the methods he used to break up with Sekai were harsh, to say the least.
- In Yuuki's route in Cross Days, he changes midway instead of at the end, for obvious reasons.
- Berserk Button: He absolutely loathes bullying. See Bully Hunter and Even Jerks Have Standards.
- Big "NO!": Makoto, at the end of the Valentine Days OVA, when he finds out the huge box of chocolates he received were not from Setsuna, but from Taisuke. Upon discovery, not only does Taisuke get surrounded by Bishie Sparkles, but he cannot hide the shyness in his now extremely feminine face.
- Bishōnen: He's noticeably more boyish-looking than the majority of the male cast, though not nearly to the same degree as Yuuki.
- Broken Pedestal: To Otome in the anime. Her feelings for Makoto are based on her image of him from back when they were in Junior High. She's quite heartbroken when she realizes how much of a Jerkass he's become.
- Bully Hunter: One of his few unequivocally positive qualities. He protects Kotonoha from Otome and her Girl Posse in one game ending, gets beaten up to defend "Yuu" in Cross Days, and apparently, Setsuna fell for him because he once protected her from some bullies.
- Can't Get Away with Nuthin': Taken to its logical extreme; Makoto is caught every time he tries to secretly nail a girl. Even lampshaded with a bit of Setsuna's reflection, which most people missed.
- Can't Take Criticism: A mild example, but Makoto can get rather pensive when someone tries to correct his behavior. He shows little patience for Kotonoha's qualms with his behavior on dates in the anime and some visual novel routes and has little patience for Sekai's teasing when he's worried she might have told someone about his crush.
- Chick Magnet: To the ridiculous extreme. The list includes at various points in the series Kotonoha, Setsuna, Otome, Sekai, Karen, Inori, Kokoro, Noan, Orahu, The Nijou twins, Ai, Youko, Mai, Manami, Hikari, Roka, Nanami, Minami, Natsumi, Kumi, and Reisei. Naturally, he is totally oblivious, and it's to the point most guys dislike him.
- Chivalrous Pervert: Averted in the anime adaptation and averted hard in the Cross Days manga. In the visual novel, while he typically has no problems screwing anyone who gives him an invitation, it's shown that he's at least capable of putting someone else's feelings above his own. In one route, he'll temporarily break up with Kotonoha because he feels that his carnal desires are hurting her. Of course, exactly how chivalrous her turns out be depends entirely on the player's choices.
- Cool and Unusual Punishment: Courtesy of Setsuna on one ending of Shiny Days.
- Death by Woman Scorned: Probably the most infamous example in anime.
- Deconstructed Character Archetype: Less so in the manga, much more so in the anime and perhaps in the games, if you pick the right options. The average harem anime protagonist is more or less seen as a Ridiculously Average Guy who's more often than not an Accidental Pervert who may or may not actually have perverted tendencies, is a Chaste Hero who is Oblivious to Love, is able to attract women through his being a generally Nice Guy, and has character traits but not so much an actual personality so as to allow the male viewers to insert themselves into the role. Makoto takes all of these tropes and elements and eviscerates them completely. To wit:
- Being a Ridiculously Average Guy at his age has been played to its logical conclusion and he's more or less a Hormone-Addled Teenager whose perversity and lust incrementally increases the more girls throw themselves at him.
- His obliviousness to love is justified by how he ends up gradually seeing the girls as sex objects and less as actual people, which isn't helped by the fact that many girls do end up attracted to him in the long run.
- His status as a plain old Nice Guy gets hampered over time due to his lust for more women, and in some instances, this drives them away from him.
- He appears to be just a boring Flat Character initially, but his personality adapts for better or for worse depending on his faithfulness to whoever the player chooses for him to romance. But in the anime, this is thoroughly demolished and he is taken to the absolute extreme negative side of the scale he becomes outright sociopathic in his pursuit of sex, and when he finds it in himself to turn things around for the better, he still shows himself to be a monstrous person whose lack of respect for people shines glaringly through.
- Depending on the Writer: Hoo boy His characterization varies wildly across all appearances. (Most of them are not favorable)
- In the original novel, he's an indecisive, socially inept average student who can range from an unrepentant Casanova Wannabe to a relatively decent human being who devotes himself to one girl and only one girl.
- In Summer/Shiny Days he's a trolling, sex-crazed pornomancer who is, ironically, completely clueless regarding all of the girls who want to get into his pants.
- In the anime, he is someone addicted to the thrill of sex and nails pretty much anyone who gives him an invitation.
- In the manga, he's an undeniable Nice Guy who actually does care for both Kotonoha and Sekai. He slips up once, but he comes to regret his actions. Unfortunately, the remorse comes too little, too late.
- In the Cross Days manga, he's a depraved sexual predator who actually attempts to rape someone.
- Did Not Get the Girl: In some Cross Days endings, if Yuuki continues to pursue him, he starts falling in love with "Yuu". However, if Yuuki pursues another girl or can't overcome his fear that Makoto might not like him, then Yuuki can make "Yuu" disappear forever. The only other girl he can commit to is Kotonoha.
- Dull Eyes of Unhappiness: Makoto◊ is shown with these eyes in a few bad endings of Cross Days.
- Dull Surprise: He apparently lacks facial expression unless things are getting too stressful. A good example is one of the bad endings of the original game: he watches Kotonoha murdering Sekai with a saw, and his look to Kotonoha immediately afterwards is one of vague bemusement. Thankfully, they fixed this in HQ.
- Enemy Mine: Mild example: He'll team up with Kotonoha's bully Otome in oder to get the former to stop harassing him.
- Even Jerks Have Standards: He hates bullying. If he catches you bullying someone, he'll call you out on it. In fact, given that School Days has very few other people who act like this, this is strongly implied to be the reason so many girls fall for him in the first place: he once protected Setsuna from bullies, causing her to fall for him; he's one of the few people in school who's nice to Kotonoha; Sekai frequently witnessed Makoto being nice, etc.
- Sort of played with in a later episode of the anime in his last meeting with Setsuna. After he starts coming on to her, she begs him to remain faithful to Sekai and offers to sleep with him right then and there if he agrees. This is enough to give Makoto obvious pause, but it's never shown what his answer was or whether or not he and Setsuna did end up sleeping together, and he definitely didn't remain faithful to Sekai in any case.
- In the true ending of Cross Days, he is disgusted at Taisuke, who continues to gang-bang "Yuu". Makoto stands up to him, but gets beaten up as a result.
- There's an interesting subversion in School Days and School Days HQ with Taisuke. In some of the routes, Makoto can witness Kotonoha being bullied far earlier than the lunchbox incident at the end. Specifically, during the festival day, Makoto can witness Otome and her posse making fun of Kotonoha for supposedly having lied about Makoto being her boyfriend. If Makoto doesn't call them out at this point, Taisuke of all people will do so instead. The subversion in this case is that the "standards" lead to the "evil," since it's only in routes where Taisuke calls out the bullies that he ends up raping Kotonoha, due to the bullies telling him that girls like forceful men.
- Barring the Cross Days manga, he will never outright rape someone, though he does still have some lecherous tendencies (moreso in the anime and spinoff games).
- Even the Guys Want Him: Everyone wants him, and we mean everyone. Taisuke from the "Valentine Days" OVA and Yuuki from Cross Days.
- Everything but the Girl: Failing to get the true ending for Yuuki's route results in this because either Yuuki stops crossdressing and "Yuu" is never seen again or Yuuki's gender is revealed and he runs away before Makoto can confess his true feelings.
- Faux Affably Evil: Crosses over into this in the Cross Days manga, which arguably portrays his most despicable and irredeemable incarnation yet. He coolly mocks Yuuki's efforts to stop him from exploiting Kotonoha and Sekai, shows a terrifyingly predatory side to him when he's with Yuuki's feminine alter-ego Yuu, and in stark contrast to virtually every other portrayal of him, he outright tries to rape Roka when his efforts to separate her from Yuuki start to fail. In fact, it could be argued that he's actually the villain of the manga.
- Flanderization: Arguably the case in the Anime and in the Cross Days manga compared to how he was in the original School Days. In the first novel, Makoto was portrayed as someone who could become addicted to sex and be a complete jerkwad to others, but it was portrayed as largely a result of not having a good grasp on reading people or talking to them combined with being extremely indecisive, anxious, and wanting to take the least troublesome path (though whether for himself or others varies). His more angry side only came out when he got fed up by the tug-of-war Sekai and Kotonoha were fighting over him, and he was so lost on what to do that even friggin' Taisuke could have more of an idea of how to proceed. Come the anime, though, and all his negative traits lack of commitment, sex-addiction, insensitivity to others are amplified to be his defining traits, without any of the contexts that made them more redeemable in the VN Otome can even be considered to lampshade this when noting the Makoto in front of her and the Makoto she remembers are two separate people. The Summer Days version of him goes further by making him pretty much a depraved Omnisexual, but even that is nothing compared to Cross Days' manga, where all his negative traits aren't just maxed out but are portrayed as deliberately done rather than him just not understanding other's feelings.
- Freudian Excuse: His parents are divorced note and his mother is always busy with work as a nurse, so a few abandonment issues might be there. Compare to his half-brother Ayumu Inou (who was repeatedly raped by Asagi Inou (his aunt) since childhood and pretty much turned into a sex beast before being rescued by his sister, Kagura), Shun Hazama (whose mother, Hatsuka, although a loving mother herself, seems to prefer Tomaru over her son's opinion or decision), or even Kei Ogata (physically and psychologically tormented by their father, later blackmailed into relationship with Midori Nagawa or Yumi Matou (both may Love Redeems in their true path)).
- The Gadfly: Especially in Shiny Days, where he can purposefully engage in most Blatant Lies without batting an eyelash, just to mess with people. It varies from innocent jokes, to lying about being lovers with his six-ish year old sister. Doing the latter sort of thing generally leads to a bad end, but the reactions can be amusing nonetheless.
- Gay Option: for Yuuki in Cross Days
- Handsome Lech: In the anime, he has few redeeming qualities other than his looks.
- HeelFace Door-Slam: In the anime. After realizing he pushed Kotonoha into the Despair Event Horizon, Makoto attempts to finally do right by her. Unfortunately, this also involved being an utter asshole to Sekai, resulting in her killing him.
- Hidden Eyes: Displayed by him a few times.
- Heroic Bastard: Judging from the fact that he has his mother's surname and that his father is using Tomoe's surname (in order to inherit Tomoe's fortune), one could reasonably presume he and Itaru were born out of wedlock. However, in Shiny Days, he flat-out states several times that his parents are divorced (he even specifies that it was messy). He most likely uses his mother's maiden name simply because he lives with her and hates his father.
- Hyper-Awareness: In the "Only You" ending of Cross Days, Makoto realizes quickly that Kotonoha is not the most stable girl and keeps his relationship with Yuuki a secret. It's also hinted that he plans on having her see a therapist after his conversation with Yuuki because he wants to make Kotonoha the last person he hurts with his jerkass ways.
- Idiot Hair: Rather fittingly.
- If It's You, It's Okay: In Cross Days' "Only You" ending, he has a reasonably (for School Days) healthy relationship with Yuuki. In the Cross Days manga, however, he comes off as a Depraved Bisexual, being willing to have a threesome with Yuuki and Sekai, despite knowing he's a guy. After Yuuki punches him out for trying to rape Roka.
- I Love You Because I Can't Control You: An interpretation of his feelings for Yuuki. Because Yuuki hates his guts at the beginning, he's immune to wanting to get banged by Makoto. As a result, Makoto has to work to get "Yuu" to pay attention to him. He then falls in love with "her"... and vice versa.
- Incest Is Relative: Is (probably unknowingly) related to both Sekai and Setsuna via both his father and his half-brother Shun, via multiple generations of incest, technically making them his half-nieces at least. He is also related to the Nijou sisters via said half-brother as well, who is also their father.
- Informed Attribute: Despite tons of girls thinking hes cute and constantly falling for him, his looks appear average at best.
- Innocently Insensitive: If he pursues Kotonoha exclusively, he'll start to seriously date her and pay less and less attention to Sekai. It isn't bad intentioned on his part, as he does interact with Sekai on occasion and still treats her like a friend, but he still breaks her heart regardless. The "innocent" part of the equation can be partially credited to Sekai not confessing her feelings to him, which seems rather dumb considering Everyone Can See It.
- Insecure Love Interest: Starts out as one to Kotonoha. It takes Sekai's prodding to get the two of them together.
- In the Blood: Makoto follows his father's footsteps in sexing up as many people as he can; some Overflow games share their universe with School Days, and Tomaru Sawagoe is in most of them; in fact, he started about 4 different big families by himself, and then made some more with his own offspring... This becomes even more pronounced when you realize he is related to about anywhere from a fourth to a third of the people he can end up with. Much like his father, he has a thing for sleeping with his own family (though in his case, it is usually unknowingly).
- Ironic Name: "Makoto" can translate to "truth", "sincerity", or "fidelity".
- Jerkass: Big time in the anime. Also in the Cross Days manga. In the visual novel, it's dependent on the player's choices.
- Jerkass Has a Point: In one route/ending he treats Sekai rather harshly, all but stating that they are through (possibly even as friends). However, he does rightly call her out on her Bystander Syndrome, allowing her "friends" to bully poor Kotonoha. Even if she was just being complacent, rather than malicious, it's clear to both Makoto and the audience that the cruel treatment has emotionally crippled the poor girl. Given Makoto's attitude on bullying, it's not hard to see why he was so angry.
- Karma Houdini: Averted most of the time. But in the Cross Days manga, he gets away with womanizing and trying to rape Roka. And since both Sekai and Kotonoha are fine with not being his only girlfriend, it doesn't seem like he's going to have problems there anytime soon. On the plus side, Yuuki and Roka get their own happy ending and wash their hands of the whole sordid affair.
- Kick the Son of a Bitch: In one of the routes, Makoto takes a pause in between all the girl posse and stands up for Kotonoha when he catches Otome and Co. bullying her. Yeah, he thinks with his cock and all, but not even he likes it when Kotonoha is at the mercy of four girls who want to make her suffer.
- Ladykiller in Love: Concerning Yuuki. This does not apply to the female characters because he always bounces back and forth between them no matter what.
- Love at First Punch: Guess how he first met Yuuki? He met the male Yuuki first when he punched him in the face for cheating on Kotonoha. He ignores that part, but then he meets his alter ego and falls for "her".
- Love Redeems: In the "Only You" ending of Cross Days, he is willing to get beaten up by Taisuke's thugs to make sure that Yuu is okay at the end. He even goes as far as telling Yuuki that nothing matters anymore as long as he's with him. Of course, he cannot tell Kotonoha about him dating Yuuki because he knows she'll go yandere on him.
- He can also commit to Kotanoha if Yuuki plays his cards right.
- Loves My Alter Ego: In Cross Days, he's more interested in "Yuu" than Yuuki no matter what route it is. However, he falls for "her" even more in Yuuki's route.
- Multi-Way Sex: Let's make some lists here.
- Original game: with Kotonoha and Sekai.
- Summer/Shiny Days: with the Nijou twins; with Otome and Karen; with Sekai and Youko.
- Cross Days: with Hikari, Nanami, and Roka.
- My God, What Have I Done?: In the manga adaptation, he's moral enough to know he royally screwed up when he cheated on Kotonoha with Sekai. Unfortunately, while Sekai accepts his decision to break up, Kotonoha is not as forgiving.
- Nice Guy: In contrast to his anime and Cross Days manga portrayals, Makoto can be played more or less like this in the visual novel, with his more jerkish or insensitive moments coming from being genuinely inept at socializing and romance and therefore unintentional. This is also a pretty accurate description of him in the original manga.
- Nice, Mean, and In-Between: The nice of the main trio (assuming we're not talking about the anime or Cross Days manga incarnations): he generally means well, but his indecisiveness and hesitancy to speak up both end up getting him into trouble. Having people like Sekai and Kotonoha as influences certainly doesn't help matters.
- In Summer/Shiny Days, he's the in-between. While arguably not as vile as some incarnations, he's still a horny teenager who can easily get any girl with an invitation to sleep with him.
- No Good Deed Goes Unpunished: A very tragic case in the manga: He's sincerely repentant of his actions after cheating on Kotonoha and tries to atone for his misdeeds. Unfortunately, the consequences come anyways. Kotonoha, having already gone mad, attempts to kill Sekai in vengeful bloodlust. Makoto, not wanting Sekai to get hurt, steps in the way and takes the stab for her. To her credit, Kotonoha doesn't try again, but the whole ordeal manages to push Sekai over the edge, and she later kills Kotonoha while Makoto is hospitalized then gloats about it to his face.
- Non-Action Guy: Seems to have some sort of severe physical deficiency, as he becomes exhausted simply from sitting near a pool without so much as setting foot in it and actually swimming. Despite this, he has limitless stamina when it comes to sex.
- Not Quite the Right Thing: Even when he tries to do the right thing, it tends to backfire on him. Playing the game entirely devoted to one girl will cause the other to become lonely and depressed, and they'll start guilting hardcore on him despite the fact that he's actually tried not to lead them on. In fact, the original visual novel's version of Makoto portrayed his potentially sexing up other girls as being indecisive in that he didn't want to hurt anyone's feelings by rejecting them, as opposed to the sex-fiend he's portrayed as in the anime and Summer/Shiny Days or the outright monster he is in the Cross Days manga.
- Off with His Head!: The official anime ending reveals that Kotonoha decapitated him after stumbling across his corpse in the apartment. She's last seen cradling his head against her chest while setting sail at sea.
- Only Sane Man: Apparently Makoto is one of the nicest and most normal members of his family. And that is saying something although the visual novel version of him can in fact live up to being deserving of it, depending on how he's played.
- Apparently, he's quite the homemaker and housekeeper, as well as a doting brother and an advocate against bullying. In fact (in the visual novel and School Days manga, at least), Makoto's actually a decent guy when his hormones aren't clouding his judgement.
- The Pornomancer: For an otherwise unspectacular person, girls seem magnetically drawn to him. Pretty much the only girl who never shows interest in him is the already-attached Nanami, but that gets thrown out the window in Cross Days when her own boyfriend's revealed to be just as much of a cheating bastard. Damn.
- Red Oni, Blue Oni: The red to Yuuki's blue.
- Shotgun Wedding: Parodied in Summer/Shiny Days. After his sexual act with Otome and Karen is exposed to the entire Katou's family, Makoto is allowed to court them, but not before being beaten up. For an extra bonus, the ending is named "Son in-law's Ritual".
- The Sociopath: The anime adaptation interprets him as a high-functioning sociopath. He has a need for stimulation that he satisfies by attracting and sleeping with his classmates, even though he's already in a relationship with Kotonoha. He has enough superficial charm and deceit to present himself as an upstanding student and Nice Guy as well as conceal his sleeping around. He shows no lasting regret for the damage he causes, save Kotonoha, and even then only when she's in his immediate presence.
- Ditto with Cross Days' manga adaptation.
- Stalker with a Crush: Becomes one towards Yuuki. At least at first.
- STD Immunity: considering how often he gets around, and his apparent refusal to use protection, it's a wonder he hasn't come down with at least one of these...
- Strong Family Resemblance: to his sister and their mother.
- Supreme Chef: He's noted to be a very good cook.
- Teen Pregnancy: This can happen in game to several of the girls he dates if he isn't careful. According to the official family tree (most up to date English version here), he actually did end up having a kid with both Setsuna and Sekai. The continuity of this is still somewhat up in the air as no games have yet to portray it or take it into account.
- This Loser Is You: Pretty much what everyone seems to forget in regards to the games: Most of Makoto's worst actions are directly initiated by the player.
- Too Dumb to Live: Who would've thought that French-kissing your (supposed) girlfriend in front of your childhood friend, who you cheated with, after sleeping around with upwards to 17 other girls, was a bad idea?
- Took a Level in Jerkass: Anime adaptation, though the Cross Days manga manages to outdo the anime - which is no small achievement.
- Too Kinky to Torture: Amusingly averted in one possible ending in Summer Days. It doesn't technically count as an official ending since the player has to massively screw up for this to happen, and it's treated as black comedy and deliberately out-of-character anyway so it's more of a joke ending, but there's a possibility that Makoto will wake up tied to a chair, courtesy of Setsuna's mother, so that Setsuna can show her love by using a whip on Makoto.
- Tragic Hero: The Manga version of him is portrayed as this. He genuinely cares about both Sekai and Kotonoha, but his Fatal Flaw of not being able to choose between them and carrying on a simultaneous relationship would not be resolved until it is too late (Kotonoha unintentionally wounds Makoto while trying to attack Sekai, and while he was in the hospital, Sekai kills Kotonoha in revenge). This, however, is in direct contrast to the complete fuckwad he is in the Anime and in the Cross Days manga.
- Depending on the player's choices, he can be like this in the game, too - though it requires the player to actively make him that way. Like the manga, but unlike the anime, Makoto is portrayed as a good person whose fatal weakness is that he's indecisive, therefore dragging his feet with girls because he doesn't want to hurt them - only to end up hurting them anyway, even when he doesn't notice their feelings at all. The tragic part can be subverted if the player gets a good ending, or Makoto's fatal weakness can result in either Kotonoha committing suicide-by-fall, Sekai's throat getting slashed with a chainsaw, Makoto himself being stabbed with a knife, he and Sekai going murderous on Kotonoha or in School Days HQ, one of the trio getting run over by a train.
- Trash of the Titans: Averted, something that Sekai lampshades when she visits Makoto's apartment for the first time.
- Unsettling Gender Reveal: Implied with Cross Days' "Love Destroyed" ending, averted with the "Only You" ending. In "Love Destroyed", Yuuki's true identity is revealed, he runs away, and a shell-shocked Makoto is seen the next day. In "Only You", Yuuki's true identity is revealed, but Makoto stops him from running away, deciding If It's You, It's Okay.
- Used to Be a Sweet Kid: invoked by Otome in Episode 11:Otome: [to Makoto] In junior high, you were more of a caring person.
- Wingding Eyes: In the ~Magical Heart Kokoro-chan~ OVA, Makoto and Taisuke sport big shiny gold starbursts in their eyes in their ecstatic response to the arrival of the Anonymous Defence Service.
- Your Cheating Heart: The anime and Cross Days versions of him practically define this trope.
- His instances of cheating on Youko in Summer/Shiny Days can be excused at very least, as she went to Paris without telling him, and forgot her phone so she couldn't call him, so he had every reason to think that she just got bored with him and didn't bother to break up with him.
Voiced by: Tae Okajima (under the name "Soyogi Tonou" in the games)
- Alliterative Name: Kotonoha Katsura
- All of the Other Reindeer: Kotonoha is the victim of bullying from Otome and her Girl Posse from before the series starts, and it only gets worse when Otome learns about her being Makoto's girlfriend.
- Aloof Dark-Haired Girl: Makoto assumes she's one at first, since she certainly looks the part. Turns out she's just shy.
- Attractiveness Isolation: She's attractive enough that all the guys want her, but none think they have a shot at getting her. This in turn causes the other girls in her class to ostracize her for being a "pheromone girl" that drives men mad with lust.
- Ax-Crazy: When she goes mad.
- Be a Whore to Get Your Man: Kotonoha starts off the series as chaste and not good at physical affection. This plays a major factor in Makoto potentially cheating on her, and outright doing so in the various adaptations. Kotonoha's response to this is to force herself to become more sexually forward to keep him.
- Betty and Veronica: The aloof and mysterious Veronica to Sekai's Betty.
- Beware the Nice Ones:
- Big Fancy House: Not including the Nice Boat. Or her huge tracts of land.
- Big Sister Instinct: In Summer Days, her reaction to Makoto banging Kokoro in very shady circumstances is grabbing her dad's golf club and hitting him upside the head. Before things escalate, Kokoro intercedes in Makoto's favor and convinces Koto to forgive him.
- Played much more impressively and straighter in Shiny Days "Rain of Carnage" ending when she discovers that Makoto and Kyouichi have been raping poor Kokoro. She kills them with her katana, rescues Kokoro, and sets the entire building ablaze.
- Also seen in Magical Heart Kokoro-chan when she becomes "Magical Word". She saves "Magical Heart" and Makoto from falling debris, then tells Doctor S that she won't forgive her for attacking Magical Heart. She and "Heart" then let their powers combine, summoning a mecha Mayo-chan and vanquishing the gargantuan Tanaka.
- Blessed with Suck: Until she met Makoto, her attractive body did her absolutely no favors. She can potentially turn it around and use her body to get what she wants.
- Break the Cutie: The girl was already a victim of school bullying from before the story started. Then things go From Bad to Worse when Makoto starts cheating on her.
- Buxom Is Better: Deconstructed! Buxom is better at winning over boys in the School Days universe... which actually has terrible consequences for Kotonoha, since she hates the attention (it's a primary reason she's so shy in the present day) and her jealous female classmates spread ugly rumors about her deliberately "tempting" boys with her huge breasts, which makes Kotonoha's life much worse. Reconstructed somewhat if you pursue her in the game. She gains more confidence in her body, and when alone with Makoto, she'll gladly flaunt her assets for him and even uses them to smother him sometimes. But when pursuing Sekai or the other girls, she plays this straight but in a less positive way, where she tries using her body to win him over, and in the Bavarois/Lust Ending, she'll verbally bully Sekai by telling her lies that Makoto likes her body more than Sekai's.
- Class Representative: In episode 9 of the Anime, Kotonoha tells Taisuke that she continually mans the reception desk for her class' haunted house because she is the class rep and a committee member.
- Clingy Jealous Girl: A consistent facet of her personality, across all routes and in all adaptations. Exactly how clingy tends to vary, with the anime taking it (like most other things) to extremes.
- Except the Harem Ending. And for the fact that in some routes she is so desperate for Makoto to love her, she'll either ignore or forgive him cheating on her. In one (happy) ending of Cross Days, she announces she accepts Makoto's womanizing, as long as she's the one he loves most. Despite that, the trope is NOT averted, as she at very least weakly issues demands to "Please stop seducing Makoto-kun!", even when she's not resorting to murder.
- Creepy Monotone: After going mad, she starts talking in this. Perhaps one of the best classic uses of this trope.
- Deconstructed Character Archetype: Hey, you know how the archetypal Kuudere character is extremely shy and yet is able to endear herself to the audience through her kindness? What if the reason she was extremely shy is because she's horribly low on self-esteem? What if she grows so attached to the first person who ever confessed to her that she goes mad when she finds out he's cheating on her, and falls into extreme denial over that fact? And in this madness and blatant denial, who could tell what she's capable of?
- Despair Event Horizon: Crossed it in the anime after being raped by Taisuke and then finding Makoto dead.
- In the game, there's two instances where she can cross it: in the first instance, if Kotonoha gets raped, and you then actively pursue Sekai without somehow dealing with Kotonoha's trauma, Kotonoha will first overhear Makoto and Sekai have sex, and then watch them have sex from outside in the snow, causing her to laugh insanely and then slash Sekai's throat with a saw the next time they meet. In the second instance, if the player is playing a path where it's clear Makoto loves Sekai more, and if Kotonoha has resorted to repeatedly having sex with Makoto to keep him interested and Makoto doesn't make his feelings for Sekai clear by refusing Kotonoha's blowjob the last time, Makoto and Sekai will visit Kotonoha to tell her Makoto loves Sekai, causing Kotonoha to commit suicide by falling off the building's balcony.
- Dude Magnet: Nearly every guy in the school wants her and nearly every girl hates her for it. Among her admirers are Makoto, Taisuke, and Yuki.
- Even Evil Has Standards: She can become violent, manipulative, and jealous depending on how Makoto treats her, but she will never kill or physically hurt him (something Sekai will do if pushed to far). If she attempts to do so (as shown in the extended version of Bloody End), she'll quickly snap out of it and come to realize what a horrible person she's become. It should be noted that she will kill Makoto and his friend Kyouchi in Summer/Shiny Days if she catches them raping her little sister Kokoro, but that isn't her being evil; it's her being protective.
- Expressive Hair: In the "Ahoge Battle" Minigame, her two strands of hair can act as blades that combat against Sekai's Idiot Hair.
- Extreme Doormat: Due to her insecurity, she can't say 'no' or stand up for herself.
- In the visual novel, when Makoto and Kotonoha watch a horror movie together, Kotonoha isn't scared of it at all, and confesses to him that she enjoys "horror and splatter movies". Who would have thought?
- Episode 10 of the anime is the start of her descent into being a Yandere after Makoto admitted breaking up with her. The only hint mid-episode has Kotonoha staring at the kitchen knives in their home, and later at the end when a Wham Shot shows her with Dull Eyes of Unhappiness.
- Eerie Pale-Skinned Brunette: After going mad.
- Evil Makeover: After going mad.
- Freudian Excuse: Let's see: Constantly bullied by no less than five girlsnote ? Check. People constantly abusing her insecurity? Check. Finally meeting people who treat her with genuinely kindness, only to have the same people stab her in the back? Check. Being raped by a person she thought she could sort of trust (her boyfriend's Bromantic Foil), and finding out her boyfriend was dancing with her best friend while she was being raped? Check. In a few possibilities, being cruelly dumped after the former mentioned event? Check. Is it any wonder she snaps the way she does on the bad endings?
- Due to the complicated game flowchart, though, it's entirely possible to have her snap and go murderous even without the rape, the only 'cheating' happening after you'd told her you'd broken up with her. The bullies are a constant, though.
- Gainaxing: Happens on a few occasions.
- Gang of Bullies: Kotonoha is harassed by no less than five girls!
- Girly Girl And Tomboy: Girly Girl to Sekai's Tomboy.
- Girl with Psycho Weapon: Some of the endings and in the anime ending.
- Go Mad from the Revelation: After being raped by Makoto's best friend Taisuke, she finds out Makoto dumped her immediately afterward. She then falls into a downward spiral of Implausible Deniability (below) on behalf of Makoto's actions and the nature of their current relationship — or lack thereof.
- Go Out with a Smile: Given a cruel twist in one of the game's bad endings, where she flashes Sekai and Makoto an insane smile as she jumps from his apartment building and crashes to the ground directly in front of them.
- Heel Realization: Trying to harm Makoto after going insane will cause her to realize how low she's sunk.
- Heroic BSoD: She suffers several of these if the game doesn't lean towards her.
- Hidden Depths: Seems like a run-of-the-mill rich, sheltered, insecure shy girl at first blush, but her sweet facade hides some deep personality flaws. More especially noticeable in the original game, in which she can display a nasty passive-aggressive side that wasn't explored in the anime.
- Hidden Eyes: Displayed often.
- High-Pressure Blood: All that's left after she throws herself off a balcony is a sea of crimson.
- Implausible Deniability: In this case it's toward the observer, denying the perpetrator's actions. Kotonoha frequently denies clearly building evidence that Makoto is cheating on her. Even after he breaks up with her face-to-face, Kotonoha starts having an internal breakdown and continues to unsuccessfully attempt to contact him.
- I Want My Beloved to Be Happy: In one ending of Shiny Days, Kotonoha is willing to part with Makoto as she knew that his heart will always have Setsuna.
- Innocently Insensitive:
- At one point she asks Sekai for relationship advice, assuming she had "experience" (read: not a virgin). Sekai asks how experienced she looks like, and Kotonoha says "extremely". They are both virgins at this point, but at least it's clear that Kotonoha does not think of or tries to insult Sekai - she merely considers her a more worldly and popular person to go for advice.
- Kotonoha also obliviously lets it slide that her mother told her to not worry about spending on her date the amount of money Sekai earlier said is more than her mother earns in a month.
- Most notably, there is when Kotonoha is talking to a depressed Sekai about her relationship with Makoto - namely about their sex life - while completely unaware that Sekai's depression stems from an unrequited love for Makoto, instead assuming she's down because her family isn't together for Christmas and thus unwittingly dumping salt on the wound.
- Ironic Name: Her name's meaning contradicts her personality.
- Lethal Chef: Though she apparently improves. Unless you count the OVA.
- Lonely Rich Kid: Before meeting Makoto and Sekai, she doesn't seem to have any friends whatsoever, and while she does have genuinely caring parents, they often go on long business trips away from home.
- Love Makes You Crazy/Love Makes You Evil
- Machete Mayhem: Her saw.
- Manipulative Bitch: In the visual novel, she can find out that Makoto and Sekai have been cheating. She responds by playing on Makoto's guilt to get him to feel her up, then takes photos and uses these to force Sekai to break things off. Depending on the path the player has been taking, this leads either to an unsatisfying ending where Makoto is together with Kotonoha but clearly unhappy, or to Makoto finally growing a spine and getting one of Sekai's better endings.
- Meaningful Name: Kotonoha is an old reading of the word Kotoba (which, by the way, means "word"). Kokoro describes her as "old-fashioned". When written in the right characters, kotoba becomes a part of the hanakotoba term, referring to the Japanese language of flowers.
- Murder the Hypotenuse: Her saw-related bad ending and the anime Grand Finale.(though in the latter's case, Sekai wasn't really a hypotenuse anymore)
- Nice Job Breaking It, Hero!: In the manga, Makoto actually does choose Kotonoha over Sekai in the end, with the latter actually accepting his decision. Unfortunately, Kotonoha decided to try and kill Sekai anyway, stabbing Makoto by accident. And then, while Makoto is in the hospital recovering, Sekai turns the tables on Kotonoha and succeeds in killing her.
- Nice Mean And Inbetween: The mean of the main trio: she may seem sugary-sweet on the outside, but her sanity is fragile (as Sekai learns the hard way). She's also the most manipulative, especially in regards to Makoto. She'll do just about anything to have him to herself. anything...
- Curiously, she's the nice one in Summer/Shiny Days. Her Yandere qualities are nowhere to be found (the few times she does resort to violence stem from a protective Big Sister Instinct rather than any deep seated insanity), and she'll even give up dating Makoto when she realizes that he'll be happier with Setsuna.
- No Good Deed Goes Unpunished: In the path where she tells Makoto that Taisuke impregnated Sekai She will be killed by Sekai herself via being tossed in the path of a train.
- Not Good with Rejection: Part of the problem is Makoto's own tendency to waffle, of course, but even in routes where he flat-out tells Kotonoha he's breaking up with her, she absolutely refuses to stop considering him to be her boyfriend and that other girls are trying to steal him away.
- Ojou: Very pretty, kinda naive, lives in a Big Fancy House, is thought of as "unreachable" by boys, envied badly by girls.
- Peerless Love Interest: At the very beginning of the story, Makoto is content simply to love Kotonoha from afar. It takes Sekai's constant prodding to get the two of them together and then the real plot starts.
- Rape as Drama:
- Kotonoha's mental and emotional breakdown hits her fully after she's raped by her Stalker with a Crush, Makoto's best friend Taisuke.
- One of the ways that Kotonoha tries to keep Makoto interested in her after he chooses Sekai is to use her body to keep him interested. Depending on how desperate she is, she can force herself on him on numerous occasions. This, unsurprisingly, nearly torpedoes Makoto's relationship with Sekai. Eventually, Makoto grows a spine and even teams up with Otome to give Kotonoha a well-deserved "The Reason You Suck" Speech.
- Red Oni, Blue Oni: The blue to Sekai's red.
- In Summer Days and Shiny Days, she is the red to Setsuna's blue.
- School Bullying Is Harmless: Are you stupid?! Regardless of how Makoto treats her, it's at least implied that Kotonoha has some severe emotional and mental issues that were caused, in no small part, do to her being bullied. She gets harassed by no less than 5 girls during a single playthrough (usually for her big chest size). It's probably why she's so attached to Makoto in the first place.
- Sex Slave: Sort of, if she ends up in a relationship with Taisuke and Makoto completely abandons her, she completely resigns on life and becomes just a living sex-toy for Taisuke's lust. And Taisuke, inflamed by her gorgeous body, has sex with her on every occasion.
- So Beautiful, It's a Curse: Not that Kotonoha ever actually says this line, but it describes her life pretty well. She's considered one of the most beautiful girls in school due to her huge breasts, and it ends up causing her to get a lot of attention she doesn't want, like lust from her male classmates and scornful jealousy among her female peers.
- Spurned into Suicide: In one of the game endings, when Makoto leaves her in favor of Sekai, she kills herself by falling backwards off a balcony and splattering all over the sidewalk in front of them.
- Stalker with a Crush: To some degree. Especially in the outcome where she steals Makoto's house key and breaks into his house every night to 'be with' him, and torture herself into insanity.
- Stock Shoujo Bullying Tactics: She's mostly subjected to two: "being cornered and verbally lashed at" and "being completely ignored". The game adds "having a lunch prepared by Makoto knocked down and stepped on", "being the target of slutshamey rumors", and "being cornered, threatened and beaten up". And having Makoto find out and pull a Big Damn Heroes for her will mark the difference between getting one of the cutest Kotonoha ends... and having Sekai pay for this with her life in a bad one.
- Surrogate Soliloquy: In this case, just Talking To The Head. While there is no exposition on Kotonoha's part, there is no mistaking to the viewer that she has perhaps irrevocably gone off the deep end, mental health-wise, on her Nice Boat.
- Talking to the Dead: Kotonoha talks to Makoto's head as if Makoto is still alive.
- Tears of Remorse: In one of the extended bad endings in the PS2 version. She has just murdered Sekai in front of Makoto in cold blood and offers herself to him, but Makoto is terrified and rejects her affections. This is enough to make Kotonoha realize that she has just done something terrible, and she breaks down in tears.
- Thanatos Gambit: Forever/Eternally. She messily kills herself in front of Makoto and Sekai to ensure they'll never be happy together.
- There Are No Therapists: Nobody but Kotonoha's little sister Kokoro and Sekai notice her fall into insanity.
- Town Girls: Femme to Sekai's Butch and Setsuna's Neither.
- Ungrateful Bitch: In a couple of Cross Days' bad endings, her way of thanking Yuki for trying to hook her up with Makoto again and stop his cheating ways is to murder either Yuki himself or Yuki's sister. To put this more in context, she does this after she overhears Makoto and "Yu" getting it on.
- Unrequited Tragic Maiden: In the endings where she does not lose her sanity or she is not a manipulator she can end up becoming this, in the anime this is played straight for a long time before the end where she loses her sanity again.
- Weapon of Choice: Japanese Saw in the first game. Crowbar or Katana in Cross Days.
- Yamato Nadeshiko: Kotonoha is soft-spoken, sweet, and beautiful. When she's still sane, that is. When she's not, the iron comes out in a lethal fashion.
- Although Sekai did stab Makoto to death, it's Kotonoha that sets a new standard for this one. One of the infamous "bad endings" in the original visual novel is one where she kills Sekai with a handsaw in broad daylight in front of a crowd of witnesses.
- In the anime, the saw comes out again, though this time it's in a considerably more private place and Makoto is too busy being dead to freak out.
- Taken Up to Eleven in Cross Days and its manga adaptation. She is so paranoid and insecure about her relationship with Makoto that she views any female getting too close to him as a threat, even if said person is trying to help her out.
- Zettai Ryouiki
Voiced by: Shiho Kawaragi (under the name "Kaname Yuzuki" in the games)
- A-Cup Angst: Briefly in Episode 5 of the anime and Visual Novel. While Sekai isn't flat-chested by any definition, seeing Kotonoha in a bathing suit makes her feel rather insecure about her considerably smaller size.
- Adaptational Villainy: In the anime, she's more selfish and less concerned with others' well-being.
- Alliterative Name: Sekai Saionji
- All Take and No Give: While it isn't bad-intentioned on her part, her relationship with Setsuna is like this, with Sekai being the taker and Setsuna being the giver. It comes from both Setsuna's willingness to do anything to ensure Sekai's happiness and Sekai's own unwitting disregard for Setsuna's feelings.
- Betty and Veronica: The grounded and adventurous Betty to Kotonoha's enigmatic Veronica.
- The Baby Trap: Some people think that Sekai wanted to do this to Makoto. The visual novel is even worse than the anime in regards to this, as far as the ethics of Sekai's behavior are concerned. Unlike in the anime, there is no doubt she is pregnant, but it's very unlikely Makoto is the father — she got pregnant almost a month after they broke up. So her decisions in murdering either Makoto or Kotonoha seem particularly harsh in such a scenario.
- Beware the Nice Ones: Shows herself over and over again to be an extremely sympathetic and self-sacrificing person, although it's not entirely clear how much of that was just a ploy to win Makoto. If it was all an act, it was an amazingly stupid one.
- In the game, it seems to be genuine, not an act. There are some paths where Sekai witnesses Kotonoha being harassed, causing Sekai to attempt to break up with Makoto to make Kotonoha feel better. Since this happens on paths where Makoto has strong feelings for Sekai, it backfires and Makoto thinks Sekai cares about Kotonoha's feelings more than his. But give Sekai credit for trying.
- Big "NO!": In one of the game endings where she stabs Makoto for leaving her for Kotonoha while she's pregnant with his baby. After Makoto admits he was worried for her since she disappeared and thanks her for not planning to give up their child, all while slowly bleeding to death, Sekai runs off screaming this line before he can fully admit how he always loved her.
- Episode 12 of the anime when Makoto and Kotonoha make out in front of her.
- A more heroic one is found in "I Love You", in which she gives a Big "NO!" upon receiving a "The Reason You Suck" Speech from Kotonoha.
- A funnier one in Shiny Days, as she attempts one last futile act of defiance before she unwillingly joins Setsuna, Youko, and Mai in their pregnancy group and is impregnated by Makoto too.
- Break the Cutie: If you root for her.
- Cannot Spit It Out: She could have saved herself and everyone else a lot of grief if she had just been upfront about her feelings for Makoto with everyone right from the start; especially in the anime.
- Childhood Friends: With Setsuna and Niki.
- Clingy Jealous Girl: She's aware of just how jealous she is of Makoto and Kotonoha, and (at least in the game) tries to take steps to counteract it. Unfortunately, she also seems to have rather poor impulse control.
- Convenient Miscarriage: In the anime ending, if you're to believe her. Kotonoha says she isn't even pregnant, after cutting her open to check, but by that point they've both gone off the deep end, so it's hard to tell who's lying... or if someone was lying at all.
- Sekai was only pregnant for perhaps two months at that point. Even if you cut her open, it's unlikely that you'll find any trace of the embryo that would be visible to the naked eye, especially if you do it with a crude butcher's knife.
- It's also speculated that Sekai wasn't pregnant, and the "symptoms" were more of stress over the really crappy situation she was in, but truly believed that she was carrying Makoto's baby. Psychological pregnancy shouldn't be discarded so easily.
- Death by Woman Scorned: In the anime and a few of the game endings, where she's killed by Kotonoha.
- Deconstructed Character Archetype: Of the Matchmaker Crush, and the "Betty" half of the Betty and Veronica trope. Turns out that giving the person you like away to another girl can really put a damper on your emotional state. And outright telling him your feelings may end up making things so much worse than they really have to be.
- Demoted to Extra: At the beginning of Summer/Shiny Days, she falls ill and basically loses almost any significance in the story. And although a romance with her is still possible, in her original role as one of the most significant of Makoto's love interests, she is replaced by her mother.
- Despair Event Horizon:
- Crosses this in the anime after Makoto dumps her in pretty much the dickiest way imaginable.
- She can cross it in the game if you're playing a path where Kotonoha and Sekai corner him on a rooftop and force him to choose between them, and if at that point he chooses Kotonoha. This leads to a scene where Sekai overhears Makoto and Kotonoha having sex, and Kotonoha in a moment of insecurity asks Makoto if he really loves Kotonoha best; Makoto reassures Kotonoha that he loves her, and Sekai was mostly good to have sex with. Sekai throws up while crying after hearing this, and six months later she stabs Makoto with a knife on the beach.
- Dull Eyes of Unhappiness: Gets these◊ in the above mentioned Despair Event Horizon.
- Dull Surprise: Sekai suffers from this when she overhears Makoto (whom she invited hopeful to have sex with for the first time) doing it with Youko, while Sekai was taking a shower to prepare. Not even after bursting through the doors to interrupt them does she have anything but her standard expression. Even Makoto who's usually guilty of this, reacts with a more appropriate (shocked) expression after being told that Youko isn't Sekai's older sister, but her mother.
- Expy: Sekai looks like a hybrid mix between Kagome from Inuyasha and Tomo from Azumanga Daioh.
- Heroic Bastard: As her father, Shun Hazama, couldn't choose the one he truly loved most, Youko, Mai, Wakaba, and Natsuhi all left him. (They're apparently still on good terms, though.)
- Fan Service With A Smile: The waitress uniform for her after school job, which can easily be mistaken as Cosplay. Not only does it leave little to the imagination, it comes complete with detached sleeves and some frills.
- First Kiss: Sekai suddenly takes this from Makoto as her reward for setting him up with Kotonoha. It all goes to hell not long after this.
- Freudian Excuse: She resents her father because she believes that he just used her mother and then threw her away after she got pregnant, leading her to fear that the same thing will eventually happen to her. That would explain a lot. This gets brought up in Shiny Days where it's implied that she is jealous of Setsuna who gets to be with both her own father Shun (who is her father too) and the boy she likes.
- The Gadfly: Mostly in the first episode; she endlessly teases and annoys Makoto about his budding relationship with Kotonoha. It's also (allegedly) the reason why she stole a kiss from him as payment for setting the two of them up.
- Generation Xerox: Her mother basically tries to turn her into a generational clone of herself, driving her into the same teen pregnancy situation she experienced herself or making sure that in many routes Makoto impregnates both of them at same time.
- Genki Girl: Mostly.
- Girl Next Door: In contrast to Kotonoha, Sekai is seemingly a typical cheery, outgoing Japanese schoolgirl.
- Good Girl Gone Bad: The most sympathetic interpretation of her character in the anime.
- Groin Attack: One episode had Sekai kneeing Makoto for groping her butt.
- Heroic BSoD: A big one in the anime.
- Gets another big one in Shiny Days when Setsuna reveals that Makoto is her boyfriend.
- Hidden Eyes: Displayed often.
- Hoist By Her Own Petard: In one of the PS2 extension endings, Sekai pushes Kotonoha onto a train line right after she and Makoto officially hook up, but Sekai is the one who ends up being hit by the train instead.
- I Can't Believe a Guy Like You Would Notice Me: Her reaction in routes where Makoto returns her feelings for him.
- Idiot Hair: Rather fittingly.
- If I Can't Have You...: The anime ending and "To My Child" has Sekai kill Makoto for choosing Kotonoha over her. The anime one-ups this trope with her accusing Makoto of only thinking of Kotonoha's happiness.
- Incest Is Relative: She is actually the niece of Makoto, since her mother be his half-sister, and this is only the tip of the iceberg.
- Innocently Insensitive: She doesn't seem to realize just how one-sided her friendship with Setsuna actually is, though it's implied to be in large part because of how much of an Extreme Doormat Setsuna is towards her specifically.
- Insecure Love Interest: Much like Makoto for Kotonoha, Sekai turns out to have been admiring Makoto from afar while holding herself back because she feels like taking him for herself is selfish (at least in the visual novel).
- I Want My Beloved to Be Happy: Sekai's initial intentions for Makoto while befriending — and setting him up with — Kotonoha. Then Sekai suddenly takes his First Kiss as a reward. Later, when Makoto confesses to Sekai, she tearfully admits she had chosen to support him when Makoto told her he liked Kotonoha. Sekai puts all the blame on him before they kiss... and so forth. See Matchmaker Crush below.
- The visual novel plays with this trope a bit more than the anime does, in that in some routes she realizes that Makoto is also falling for her, which leads her to try to distance herself from him because she doesn't want to become the Spanner in the Works — which, of course, can lead to Makoto tracking her down himself and confessing his own fully-realized feelings.
- Jerkass: Many fans seem to see Sekai as this, given how she claims to want Makoto - and later Kotonoha once she befriends her - to be happy, but is perfectly willing to keep meddling in their relationship by offering herself to Makoto to practice sex on. In the original game it's a bit subverted, as it was implied to be from sharing Makoto's fatal flaw of indecisiveness and things going farther than she intended. In the anime, manga and Cross Days it's instead implied that she's knowingly messing with Makoto's feelings or even that she got him and Kotonoha together just to deliberately tank things and catch him on the rebound, being far less considerate of her friend's feelings than in other interpretations.
- Hell, even her most sympathetic interpretation in the original School Days has shades of this. When Makoto first starts dating Kotonoha, the way the rest of the girls believe Kotonoha stole Makoto from Sekai implies that the latter never once told her friends what the actual reason she was spending time with him wasnote - resulting in Makoto and Kotonoha getting a lot of flak from people that Sekai could have easily prevented. This isn't even counting her friendship with Setsuna, in which, while portrayed as her being Innocently Insensitive, still shows her often not bothering to consider Setsuna's feelings - and it's made even worse once it's revealed that the reason Setsuna never pursued Makoto herself was because she'd asked Sekai to help her get close to him much like Makoto asked Sekai to help with Kotonoha. However, Setsuna noticed Sekai falling for him and bowed out, which Sekai seemed to just accept with no further inquiry - basically letting Setsuna sacrifice her own shot at Makoto for the sake of a shot Sekai herself was ultimately was too scared to take until potentially too late for either of them!. In fact, this same thing comes back to bite her in one route when Makoto learns Kotonoha was being bullied by Otome and the Trio; even when Nanami takes responsibility for it and reveals Sekai wasn't in on the plan, Makoto still holds Sekai accountable for the fact that, as Kotonoha's friend, she should have known about the harassment and either done something about it or told him - or worse, that she knew about the bullying but said nothing because of how it worked in her favor. Something that both sinks her chances with him and seemingly ends friendship.
- Jerk with a Heart of Gold: She tends to be rather selfish and entitled in most of her appearances, and is not above being manipulative just to have Makoto all to herself. That being said, in certain paths of the visual novel, she at least tries to put Makoto and Kotonoha's feelings above her own. How well she succeeds without drifting back into Jerkass (or worse, Yandere) territory depends on how well Makoto treats her.
- Jerk with a Heart of Jerk: The above-mentioned Cross Days interpretation comes across as this, as well as in the manga version.
- Laser-Guided Karma: In Cross Days, it's to be noted that no matter what ending there is, she never ends up with Makoto after all she does to keep him in School Days. Even the scene where it looks like Makoto and Sekai are going to have sex, complete with Sekai getting naked, ends abruptly as Makoto leaves before they can actually do the deed. Yuki calls her out on everything as well, which helps.
- Love Makes You Crazy: In the anime, she responds to Makoto's persistent womanizing by violently murdering him with a kitchen knife.
- Also in one ending of the visual novel, in which she responds to Makoto's choosing Kotonoha over her by violently murdering him with a kitchen knife on a beach. There's another ending where she instead responds by pushing Kotonoha in front of an oncoming train.
- Manipulative Bitch: In the manga.
- Matchmaker Crush: Sekai helps Makoto and Kotonoha hook up
and puts a lot more effort into it than you would expect. And then she gives herself a reward for her efforts by surprise-kissing Makoto. This does not end well. See I Want My Beloved to Be Happy above.
- It turns out that Sekai originally played this role for Setsuna, but ended up developing her own feelings for Makoto and turned to Setsuna for help.
- Meaningful Name/Punny Name: As everybody knew, Sekai means "the world". She is the one who created a "world" between Kotonoha and Makoto. And as someone once noted, "the world is unstable".
- Murder the Hypotenuse: Reversed in the manga (where after Kotonoha fails to kill Sekai, Sekai is the one who kills her and even gloats about it in front of a despaired and hospitalized Makoto) and also in some new bad endings from the PS2 version, which involve trains. One of these endings shows Sekai pushing Kotonoha on the line, but falling in as well and then getting hit by the train when Makoto is bailing Kotonoha out. The second features Makoto getting killed in front of the girls after he saves Sekai from her fall, the third kills off both girls in front of Makoto, and the fifth one involves Sekai succeeding at killing Kotonoha by throwing her in the path of the train as it passes, despite Makoto attempting to save her. NICE TRAIN, INDEED.
- That last one is the one later used by the School Days HQ re-release; Sekai pushes Kotonoha into the path of a train and breaks into psychotic laughter as Makoto looks on in horror.
- My God, What Have I Done?: She seems quite horrified in "To My Child" after stabbing Makoto. The feeling is played up in the anime ending where she stops stabbing and sees his vacant eyes staring up at her as if she realized that she killed the boy she loved.
- Nice Mean And Inbetween: The in-between of the main trio: She's (probably) not as unstable as Kotonoha, and she'll even bow out when she sees that Makoto is falling for Kotonoha. However, she does have a selfish, manipulative streak. In some routes, she has no problem lying and withholding information to keep her relationship with Makoto a secret (unlike Makoto, who just can't bring himself to say anything). Also, she's usually not as murderous as Kotonoha, but she doesn't take cheating all that well. (Understandably so.)
- In Shiny Days, she's the mean one. She shows little regard for Setsuna's feelings, even pretending to be sick so she can lounge while Setsuna repeatedly takes her shift. This backfires spectacularly as she is Demoted to Extra as a result, with Setsuna, Kotonoha, and countless secondary and tertiary characters having a higher shot at ending up with Makoto than her.
- Not Good with Rejection: For the anime ending and two of the visual novel's Bad Ends, she ends up killing Makoto/Kotonoha.
- Properly Paranoid: In Cross Days, she's afraid that if Makoto will walk around the festival with other people (such as for Roka's jealousy plot), he'll end up cheating on her. Makoto will prove her right more often than not.
- Rape as Drama: If she starts dating Taisuke in the visual novel, he ends up raping her (or pressuring her into having sex even if she's initially reluctant, if you want to put things mildly). A lot. On one path, in a shining moment of character for Makoto, he catches Sekai visibly upset coming out of a room where Taisuke had just raped her, and later masturbates to the thought of how cute she looked. To be fair, though, Taisuke doesn't explain it to Makoto as a rape (or even considers it to be rape himself), he explains it as Sekai having told Taisuke to put a condom on, but Taisuke having run out and ejaculating inside Sekai anyway. This may have caused Makoto to think the incident was less serious than it really was.
- Red Oni, Blue Oni: The red to Kotonoha's blue.
- Romantic False Lead: More-or-less serves this role in Cross Days. While she does have endings of her own, most paths have the goal involving her and Makoto breaking up, in order to make room for Kotonoha. This also serves as a good example of when the subject is made too sympathetic, since Makoto just ends up looking like even more of a jerk.
- Slasher Smile: In the ending "Pushed Too Far", she looks positively demented as she watches Kotonoha get hit by a train and laughs maniacally as the traumatized Makoto holds his girlfriend's severed arm.
- Teen Pregnancy: Like mother like daughter. In some routes.
- There is even an ending of that name in Summer/Shiny Days.
- According to the official relationship chart, it does canonically happen, but the exact timing of the pregnancy and continuity is up in the air, as no game has yet to portray it outside of optional routes.
- Tomboy and Girly Girl: Tomboy to Kotonoha's and Setsuna's Girly Girls
- Tomboy with a Girly Streak: She's not a complete tomboy, but more of a girly Tomboy, since she acts tomboyish but has yanderish moments.
- Town Girls: Butch to Kotonoha's Femme and Setsuna's Neither.
- Took a Level in Jerkass:
- The manga adaptation has her noticeably less concerned about Kotonoha's feelings, and far more aggressive in her pursuit of Makoto, while her personal insecurities are given much less attention.
- She has a more selfish, entitled attitude in Summer/Shiny Days, even going so far as lie just to get Makoto and Setsuna to break so she can have him all to herself.
- Tsundere: Sekai seems at first to be a Type B
- Unwitting Instigator of Doom: Makoto was actually rather normal and faithful to Kotonoha until Sekai seduced him.
- Weapon of Choice: Knives
- Woman Scorned: Particularly in the anime.
- Yandere: Holy crap, Sekai is creepy in the manga and some of the game endings

- A-Cup Angst: Setsuna is pretty short and underdeveloped for her age and is rather self-conscious about it.
- Taken Up to Eleven in Summer Days/Shiny Days, in which Setsuna works at Radish Restaurant in place of Sekai and has to wear a Stripperiffic uniform while working alongside the much bustier Oruha and Noan. Also, the game introduces Kazuha, Futaba, and Karen, who are not only younger than her but also much more developed.
- Affectionate Nickname: In Summer Days/Shiny Days, after she and Makoto have sex for the first time and begin dating, she asks Makoto if she can address him as "Mako-chan", and in return, allows Makoto to call her, "Se-chan". Makoto eventually agrees, but only when they're alone.
- All Take and No Give: Her relationship with Sekai. Partly because Sekai disregards Setsuna's feelings, partly because Setsuna is so devoted to Sekai that she is willing to completely steamroll over other people in order to ensure that Sekai is happy.
- Ascended Extra: In Summer Days and Shiny Days she is promoted to be the third main heroine.
- Babies Ever After: In certain game paths via a postcard.
- The game paths are "Bavarois" (Sekai ending) and "Carnal Desires" (Kotonoha ending). The postcard arrives in a post-credits scene called I'm the Wife if you got either of those endings in a path where Makoto and Setsuna have intercourse during the festival at the end of Episode 4.
- In one ending of Shiny Days, Makoto impregnates her, Mai, and Youko, and the four of them then try to convince Sekai to become pregnant too...
- Berserk Button: People who make fun of her rather young looks or otherwise belittle her tend to be the recipient of a swift kick in the face, Taisuke being the usual culprit. And that's not even talking about what happens to people who try to hurt Sekai in any way
- Cat Smile: Sports one during her drunk babbling during the school festival.
- Childhood Friends: With Sekai. They're also half-sisters.
- Class Representative: For her, Makoto, and Sekai's classroom.
- Defrosting Ice Queen: In her path in the game.
- Disproportionate Retribution: When Nanami skips her shift during the school festival to go on a date with her boyfriend, she accidentally leaves her phone behind. Setsuna gets mad when she's unable to contact her, so she copies Nanami's entire address book from her phone.
- Emotionless Girl: Seems to be, although she's really just rather quiet about her emotions.
- Expy: Of Satsuki Shigehara from Large Pon Pon.
- Wearing a ribbon and into bondage with a whip? Midori Nagawa.
- Extreme Doormat: Played straight in School Days, where she'll do anything to make Sekai happy. Subverted in Summer/Shiny Days as Sekai has to use Makoto as a bargaining chip just to get Setsuna to take her place at work.
- Guile Hero: She's quite adept at manipulating people, and can potentially be very ruthless in her dealings with them, but usually works in such a manner that it's actually to their own benefit.
- Heroic Bastard: Same deal as Sekai. Although it's also hinted that Shun does marry her mother Mai, so this trope maybe subverted.
- Idiot Ball: It applies most of all for Setsuna when she allows herself to kiss Makoto while he was sleeping, and for letting Makoto have his way with her if he promised to watch out for — and be exclusive to — Sekai. Makoto's past actions should have clued her in that this tactic was not guaranteed to work. Nevertheless, Setsuna's crush on Makoto is most likely an ulterior motive for this.
- Given what's revealed about her (see Matchmaker Crush below), it's also possible that Setsuna was acting out of desperation to get them together - because otherwise it'd mean she'd sacrificed her own chance to be with Makoto for nothing.
- In Vino Veritas: While drunk during the class party, she hugs Makoto, offers to let him feel her breasts, and asks if he thinks that her breasts are small. She also asks him if he really loves Sekai or not; if Makoto says that he hates Sekai, Setsuna will suggest that Makoto should go out with her instead, and asks if she can call him "Mako-chan".
- I Want My Beloved to Be Happy: Ironically, she ends up regretting it in the end.
- Lap Pillow: In the visual novel, to Makoto.
- Little Miss Snarker: When she's with a group of friends, Setsuna can be pretty sarcastic towards them.
- Taken up to eleven in Summer Days/Shiny Days, where she effortlessly cuts down Makoto nearly every time he tries to act cool.
- Living Emotional Crutch: For Sekai. Part of her justification for setting Makoto up with Sekai is to get him to fulfill Setsuna's role as this once she leaves.
- Love Makes You Evil: Her devotion to Sekai leads her to do some pretty terrible things to Kotonoha, whom she doesn't hate but still views as an obstacle to Makoto and Sekai's relationship.
- Matchmaker Crush: She has a crush on Makoto but decides to make sure he stays with Sekai instead, so he can protect her before she goes to live abroad.
- It turns out that Sekai was originally trying to help her win Makoto, but ended up developing her own feelings for him, and Setsuna quietly bowed out when it became apparent.
- Meaningful Name: Setsuna means "a little time" before she has to bid farewell to Makoto and Sekai and go to Paris with her mother. However, if Makoto chooses her in Summer Days/Shiny Days, this trope will be subverted.
- No Sympathy: For anyone other than Sekai and her friends.
- Subverted in (Shiny) Summer Days. As it turns out, when Sekai is not involved in the situation at all, Setsuna does have a lot of sympathy towards the problems of others, even if their desires go straight against her own.
- Older Than She Looks: Looks very young for her age, and she's very conscious of such a thing. And she's no exception to Makoto banging everything in school that has
a vagina anda schoolgirl uniform.
- Supplementary reveals that Setsuna's third-generation in the inbred of the Inou Family (her father is from the Hazama Family, but is also a half-brother with her mother, Mai), unlike Sekai who's only second-generation. Genetic Problem is very much the cause.
- Parental Abandonment: As with all of Shun's children except for the Njiou sisters, Setsuna's father hasn't been in her life for over a decade.
- Red Oni, Blue Oni: In Summer/Shiny Days, the blue to Kotonoha's red.
- Rescue Romance: Her crush on Makoto started after he defended her from some bullies.
- Roundhouse Kick: Gives one to Makoto when she confronts Makoto for cheating on her with Sekai, after Makoto asks her to "join" them in having sex.
- Shrinking Violet: In Summer Days.
- Stalker with a Crush: She tried to be more discreet than the others... until Kotonoha caught her kissing Makoto in his sleep.
- Sugar-and-Ice Personality: Although silent-looking and almost emotionless, she's very caring towards Sekai.
- Teen Pregnancy: Certain endings of the original game have an epilogue that feature Setsuna showing up out of the woodwork to cheerfully tell Makoto and whoever he's dating at the time that she's pregnant with his child (if you got those endings on a route where Makoto and Setsuna sleep together during the school festival). There's also an ending of Shiny Days in which she ends up pregnant by Makoto, along with her own mother and Sekai's mother.
- Canonically, she actually is impregnated by Makoto eventually, but, just see the same entry under Sekai further up.
- Tomboy and Girly Girl: Though not girly, she plays Girly Girl to Sekai's Tomboy.
- Town Girls: Neither to Sekai's Butch and Kotonoha's Femme, also plays this towards Nanami and Hikari
- Took a Level in Jerkass: While in the games, she is one of the nicest members of the cast, her anime incarnation is noticeably more aggressive and willing to harm others in her quest to make Sekai happy.
- Third-Option Love Interest: She is the most significant girl in the series right after Kotonoha and Sekai.
- Wardrobe Malfunction: Courtesy of Inori in Shiny Days.
- Well-Intentioned Extremist: She wants Sekai to be happy, no matter what. And she's more than willing to destroy Kotonoha and Makoto's relationship to achieve this.
- Whip It Good: In Summer Days's bad ending, after Makoto gets both Youko and Sekai pregnant, Setsuna ties Makoto down and whips him, dominatrix-style, with Mai as her assistant.
Voiced by: Ryouko Tanaka (under the name "Hikaru Isshiki" in the games)
- Babies Ever After: She has a child with Makoto in the "Sex friend" ending, much to Makoto and Sekai's shock.
- Characterization Marches On: In early episodes of the anime, Hikari is established to have a crush on Taisuke like she did in the Visual Novel. This doesn't stop her from sleeping with Makoto late in the series, however. Worse, her crush on Taisuke is never mentioned again.
- Childhood Friend Romance: Apparently, Hikari is the unlucky variant for Taisuke as well. She ends up roped in Makoto's bedsheets, but unlike the other girls, Hikari actually acknowledges this as a mistake from the beginning and is the first one to desert him.
- In the game, however, if the player is romancing Hikari, it only happens on routes where Taisuke has sex with Kotonoha, so in that particular case maybe Hikari isn't that unlucky.
- Also in the game, Makoto can actually help set them up as a couple in a late-game subplot, turning her into a Victorious Childhood Friend.
- Covert Pervert: In the original game. She blurts out during a conversation that she finds Dating Sims to be an interesting concept, and in one scene, when Kotonoha is being raped by Taisuke, she peeks and can't tear her eyes away from the sight. Oh, and did we mention that Makoto can mess around with Hikari while Taisuke is having his way with Kotonoha?.
- Comes up again in one route of Shiny Days. When she sees Oruha having sex with one of Radish's customers, she starts masturbating to the sight. In addition, when Makoto starts sexing her up from behind, she lets him do it.
- The Ditz: She's the most childish and immature of Sekai's friends.
- Friends with Benefits: One of her two endings is this: Hikari and Makoto do it whenever the former feels like it, but they still pretend as though Hikari hates Makoto at school. Oh, and this is the ending in which she has a child with him. The other ending is a Harem Ending, in which Makoto has sex with different girls every day behind Sekai's back.
- Girly Girl And Tomboy: Girly Girl to Nanami's Tomboy
- Girlish Pigtails: Known for her squid-rings hairstyle. She's almost unrecognizable when she lets her hair down.
- Karma Houdini: In the anime ending, despite ending up tangled within Makoto's bedsheets.
- Only Sane Man: Like most of the other girls, she'll mercilessly bully Kotonoha. However, unlike Otome, she'll actually not default to this - in fact, rather than attacking Kotonoha because of an assumption based on her looks, she'll only seem to treat her badly if she thinks Kotonoha is trying to actively break up a relationship between Makoto and Sekai. This ironically makes her one of the few girls who don't bully Kotonoha without first having at least a semi-understandable reason for it.
- Screw This, I'm Outta Here!: In the anime, she's the first of the girls to bail out on Makoto once everyone learns he may have gotten Sekai pregnant.
- Shipper on Deck: For Yuuki and Roka in Cross Days
- Stalker with a Crush: In the scene leading up to her route, Makoto catches her following Taisuke while he's in turn following Kotonoha.
- Teen Pregnancy: With Makoto in her "Sexfriend" route, if he doesn't pull out in time. However, she's shown to be surprisingly accepting of it - if not outright happy about it.
- Third-Option Love Interest: One of the possible ones in the visual novel.
- However, unlike fellow third options Otome or Setsuna, who already had feelings for him by the start of the visual novel, Hikari starts off disliking Makoto because she thinks Makoto is going out with Sekai and therefore causing Sekai to keep ditching her friends at lunch. So the player has to work to get Hikari to be a "third option love interest," and even then Hikari's interest is piqued only once she realizes from firsthand experience that Makoto is really good in bed. However, if she ends up getting pregnant with Makoto's child, she's shown to be remarkably okay with it - in fact, she even seems happy with with development.
- Took a Level in Kindness: In certain paths in Cross Days.
- Took a Level in Jerkass: But while she is nicer to Kotonoha on those paths, those also have her help destroy Sekai's relationship with Makoto while Hikari is rewarded for it, by means of Taisuke dancing with her at the bonfire.
- Town Girls: Femme to Nanami's Butch and Setsuna's Neither
- Tsundere: In the original game. Surprisingly, though, not for Makoto! She has a crush on her childhood friend Taisuke, though it isn't ever brought to the forefront except in one particular sequence of events. She's also implied to be the best match for him, as she's unlikely to be the sort of girl to let him take advantage of her. Of course, like everything else that isn't central to the core Love Triangle plot, this little tidbit goes out the window in the anime.
- Well-Intentioned Extremist: Like Setsuna, she wants to help Sekai with her love life. And she's more than willing to threathen Kotonoha and plot devious deeds behind her back to do so. And in Hikari's case, it could also be a case of harboring resentment towards Kotonoha because of Taisuke's crush on her though it should be noted that she didn't seem to have a bad opinion of Kotonoha herself unless she thought the latter was actively trying to seduce Makoto away from Sekai.
- What the Hell, Hero?: Is usually the one who gives this treatment to Makoto and then some, in all adaptations and spin-offs.
Voiced by: Chiaki Takahashi (under the name "Miko Fujimura" in the games)
Sekai's tall, tomboyish, sporty friend. She went to the same middle school as Kotonoha, and therefore knows a lot of rumors about the latter.
- Aloof Dark-Haired Girl: While not exactly a classical beauty, she's the tallest and seemingly most mature of Sekai's friends, and she's certainly aloof until that videotape gets out....
- Big "NO!": In the anime, she gives out a huge one when she realizes that Otome's "friends" videotaped her and her boyfriend having sex and are showing it to the whole school. Could you blame her?
- It's even worse in the game, School Days HQ, since you actually get to see the tape of Nanami and Kyouichi having sex, and you find out that Kyouichi made her call him "Onii-chan" as a turn-on, that Nanami puts on a really high, feminine, not-usually-like-her voice when having sex since she loves him so much, and he's planning to have her call him "Goshujin-sama" meaning "Master" the next time they make love. So in the game, not only did everyone get to watch Nanami and Kyouichi do the deed, but they're kinky, too! It's embarrassing enough that other people watched you have sex with your loved one; having other people watch you have role-play sex with your loved one has got to be torture.
- Caught with Your Pants Down: Or better said, Filmed With Her Mini Skirt Up.
- Even the Girls Want Her: Has a scene with with Roka in Cross Days
- Green-Eyed Monster: Resents Kotonoha for her large bust and the attention boys give her for it, which can lead to Nanami bullying her and spreading nasty rumors.
- Heroic BSoD: Has a brief one when everyone sees the tape featuring her and Kyouichi going at it. In the game, she simply cries at the sight; in the anime, however, she gives a massive Big "NO!" and falls to her knees.
- Get hit with another one in Cross Days where Kyouichi is revealed to be a cheater.
- Huge School Girl
- Laser-Guided Karma: Her and Hikari's actions in one of the routes to drive Kotonoha away from Makoto to bring him and Sekai together backfire spectacularly, actually putting Makoto and Sekai's friendship in jeopardy, which came from Makoto's sheer disgust for their actions.
- One Side of the Story: Played with in the visual novel. Despite supposedly being less petty then the other girls, she never seems to realize that Sekai and Makoto weren't initially an item and never thinks of such as a possibility for why Makoto may have ended up with someone else. Granted, this is only true if it's the Makoto from the visual novel, but the point still stands that she never even seems to think the situation is anything else then Sekai being victimized, let alone it being different from what what she thinks it was at first glance.
- Arguably the biggest example of this is near the end of a route where Makoto has committed to Kotonoha. Nanami blames Makoto for Sekai falling into depression on the assumption he did something to her, completely oblivious to the fact that it was Sekai's dishonesty about her own feelings that caused an issue. Even though Nanami was right that Makoto's the reason for Sekai's state, it was because Makoto was both unaware of Sekai's feelings and already committed to Kotonoha by the time she finally said anything, so it was that he couldn't return her affections as opposed to his having attacked or demeaned her. Skewing things even more is that Nanami didn't even know Sekai and Makoto were never together to begin with, Sekai's time with him having been to coach him on how to get together with Kotonoha (and depending on player choice, never going farther than that), so Nanami is basing the entirety of her accusation on a version of the story that ignores any possibility of fault on Sekai's part.
- Another major example is when she has Otome and her gang bully Kotonoha on the assumption that she's protecting Sekai from getting Makoto stolen from her, completely unaware that Sekai had actually been helping Makoto try to go out with Kotonoha and that Sekai herself had arguably become the intruder in the relationship. Nanami's actions are done with even Sekai herself being left out of the loop, which backfires spectacularly when Makoto finds out about the bullying and assumes Sekai was either in on it or was aware of it and didn't tell him because it conveniently kept Kotonoha away - something that not only torpedoes Sekai's chances with Makoto but also causes severe damage to their friendship. All because Nanami never bothered to confirm what the situation was and jumped to endorsing bullying as the first course of action.
- Only Sane Woman: It helps that she's the only girl in the series who doesn't get involved with Makoto. At least until Cross Days, where, with Hikari's and Roka's help, Makoto got even her. Though in that same game it turned out her boyfriend was a cheating jerk who once raped her sister. Couple this with her actually being one of the primary instigators of bulling against Kotonoha for no other reason then envy toward the latter's chest, and it makes it more of a cause of "only sane woman except for with one person."
- Passionate Sports Girl: Basketball star.
- Tomboy and Girly Girl: Tomboy to Hikari's Girly Girl
- Town Girls: Butch to Hikari's Femme and Setsuna's Neither
- Theme Naming: With her sister, Yae.note
- Well-Intentioned Extremist: See Hikari and Setsuna's entries. It's particularly jarring in her case, considering her status as one of the most mature characters of the series and the Only Sane Woman, seeing how she has no qualms with spreading nasty rumors about Kotonoha and getting an entire sports club to help a group of bullies, also from said club, to make Kotonoha miserable just to drive her away from Makoto, freeing the way for Sekai. Even Sekai herself is shocked by what Nanami did.
- At least part of this comes more from her general dislike of Kotonoha, who mentions that Nanami had bullied her in middle school - something else that contradicts her supposedly-mature nature when it's revealed Nanami did this simply because Kotonoha had bigger breasts then her.
Voiced by: Haruka Nagami (under the name "Yuki Matsunaga" in the games)
- Alpha Bitch: Though she's less fashion-obsessed and more tomboyish than the standard.
- A-Cup Angst: Even though her bust isn't as small as Setsuna, Otome does show a complex of not being as well endowed as Sekai, Kotonoha, or her younger sister Karen.
- Be All My Sins Remembered: Played with; when Makoto catches her and the Trio bullying Kotonoha, he asks her to make sure the latter stop their harassment as he's sure she was just was following the crowd - completely unaware that she was actually the ringleader under Nanami. That her old friend and the person she is in love with is so incapable of seeing her as a bully seems to completely defang her, becoming meek and submissive to his request in stark contrast to her normally abrasive nature, implying that his untarnished view of her made her feel ashamed of something for oncenote .
- Berserk Button: Don't ever say that she has "no boobs".
- Sister-Sister Incest: In Summer Days, Makoto can get a threesome with her and her little sister, Karen.
- Childhood Friend Romance: Unlucky variant to Makoto. It's possible for her to be victorious in the visual novel, where you can end up with her as a Third-Option Love Interest.
- Even Evil Has Standards: Varies. One player choice makes the difference between whether she awkwardly tries to offer some comfort to a crying Kotonoha who's been publicly dumped by Makoto, or manipulates Taisuke into raping her.
- Demoted to Extra: In the manga.
- Freudian Excuse: While Otome has both a father and a mother unlike many of the other characters, her family is far from peaceful, as her father is a womanizer and her mother pretty much goes around and threatens to kill anyone who dares to cheat with her husband. Oh, and let's not forget the fact that her sister outgrew her in a certain area. These pretty much summarize her hatred toward Kotonoha (who she believes to be a temptress), Roka (whose mother was involved in an affair with her father), and Hanon (a Femme Fatale).
- Hopeless Suitor: Makoto never notices her affections, thinking her just a good friend. Karen has to point this out to him in Shiny Days.
- Incest Is Relative: Averted. Neither of Otome's parents are related to Makoto's father, Tomaru, so a relationship between them is perfectly fine.
- Ironic Name: "Otome" means maiden. She's a tomboy. On the other hand, she's the only one of Makoto's love interests in the game to not get pregnant in any routes.
- Irony: She's one of the very few romance options who's not related to Makoto in some way, shape or form, yet was Friendzoned before the game's events and her ending is well off the beaten path. Additionally, there's the fact that, aside from Hikari, the only other love interest in the original School Days she shares the "non-incest option" status with is also the only girl she actively hates and harasses on a regular basis; Kotonoha.
- Jerkass: Among the biggest ones in the anime, although she gets a slight moment of redemption when she dumps Makoto in Episode 11, after hearing about his public rejection of Sekai and realizing that he has changed dramatically from the person that she fell in love with.
- Jerk with a Heart of Gold: In the visual novel. Much of her behavior is implied to be the result of either her Girl Posse egging her on or her putting on a show to keep/earn their respect, coupled with her family's internal problems. Contrasting her brash nature, she positively melts around Makoto and will do just about anything he asks her to (including stopping the others from bullying a classmate). Shiny Days, meanwhile, plays this trope straight; although she's generally abrasive (particularly to her friend, Ai), she's very kind and sympathetic to Setsuna's plight once she gets to know her, and she's a proactive sisterly figure to Inori.
- Jerk Jock: She's a basketball star and a bully.
- Laser-Guided Karma: During middle high, she intervened and prevented Ai and Makoto from successfully confessing their feelings. As karma falls back, she failed in her own confession for him too.
- Likewise, her bullying of Kotonoha can result in being the catalyst for Makoto and Kotonoha getting together in one route, which subsequently seems to shame her out of ever perusing Makoto again.
- In an another example for School Days itself, her advice that caused Taisuke to rape Kotonoha causes Makoto to come back to her and declare that he is Kotonoha's boyfriend.
- Loving a Shadow: In the anime, Makoto was a nicer guy back in junior high, and Otome is still in love with that guy who no longer exists. Eventually, she is forced to see that the person she fell in love with and the person in front of her now aren't the same anymore.
- Passionate Sports Girl: The star of the basketball team.
- Patient Childhood Love Interest: Can be played straight though in other cases she remains a Hopless Suitor.
- Shotgun Wedding: Parodied in Summer/Shiny Days with Makoto.
- Third-Option Love Interest: In the visual novel, it's possible to end up with her. She's set up to be a literal third option, as her route only appears late-game, after Makoto gets so fed up with Kotonoha and Sekai fighting over him that he rejects them both publicly.
- Theme Naming: With her mother, 
- Tomboy and Girly Girl: Tomboy to her trio's girly girls
- Tomboy with a Girly Streak: She plays basketball and acts masculine, but has a girl posse and a huge crush who she wants to see her as a girl.
- Tsundere: A Type A. Lampshaded in her ending, where her Girl Posse ask her how come she and Makoto can stay together if they keep squabbling all the time, and Otome just shows them a picture of them kissing.

- Abhorrent Admirer: to Kotonoha in most media, to Makoto in the "Valentine Days" OVA, to Yuuki in Cross Days
- Ascended Extra: Taisuke first appears in Pure Mail, in an extremely minor capacity, five years before his appearance as a character in School Days.
- Bitch in Sheep's Clothing: Come Cross Days. Although, surprisingly enough, averted in the Cross Days manga in which he even (unknowingly) helped Yuki.
- Bromantic Foil: Possible deconstruction, considering what he does to Kotonoha in the anime and one of the game paths.
- Continuity Nod: His older sister, Miki from Pure Mail, is mentioned several times in the game and the fact that Miki and Kei are an Official Couple.
- Depraved Bisexual: Come Cross Days.
- Dogged Nice Guy: Starts like this towards Kotonoha. In one of the Sekai/Makoto game endings, he actually does score with her and they become the Beta Couple. Unfortunately, there's more to his character than this...
- In some visual novel paths, he also acts this way towards Sekai, which may or may not lead to him "raping" her and getting her pregnant, which in turn leads her to kill Kotonoha in "Pushed too far".
- Freudian Excuse: See Rape as Backstory.
- Heroic Bastard: Due to his father Ayumu Inou's marriage to Rurika Washino, it's very likely that he and Miki were conceived out of wedlock, as his mother was one of Asagi Inou/Nagawa's friends, who helped her rape Ayumu in his youth.
- Gay Option: Played for Laughs in the Valentine Days OVA, for which Makoto responded with a Big "NO!" (above). However, played not for laughs in Cross Days.
- Genre Blind: The most charitable interpretation of what he did to Kotonoha in the original game wherein he rapes her while she continues to protest. With girls pretend-protesting during sex being a very common kink in Japanese porn, added to Otome telling Taisuke that girls loves forceful men, the implication is that Taisuke was such an idiot that he thought Kotonoha's genuine, unmistakable protests were pretend, as if they were both in a regular porno.
- I'm a Man; I Can't Help It: If he gets Kotonoha into a relationship with him (either by rape, or by comforting her broken heart), he starts having a lot of sex with her (regardless of whether she wants it or not) supposedly because he's crazy about how beautiful and well-developed she is.
- Karma Houdini: Gets clean away with raping and/or at least taking advantage of Kotonoha or Sekai, depending on the route you take. Particularly egregious seeing that almost everyone else got what they deserved.
- And in Cross Days, he gets away with gang-banging Yuki depending on the ending. However, in the true ending, Makoto stands up to them, but he still gets his ass kicked.
- Perhaps the most jarring example is the ending in Cross Days where he is just barely stopped from raping Kotonoha by Yuki, but then goes on to happily dance with Hikari at the bonfire while Yuki just gives an approving smile. Of course, we have to remember that the cause was Otome who incited him.
- Like Father, Like Son: Averted. Taisuke never had a chance to get around like his father, Ayumu. Played straight in terms of their look, though.
- Plucky Comic Relief
- Rape as Backstory: From Pure Mail After it's revealed that he was raped by Kei, who mistook him for Miki during the former's attempt to reconcile with her.
- Stalker with a Crush
- Took a Level in Jerkass: Especially notable in Cross Days. While most of his more terrible actions in School Days happened because Taisuke is just that much of an idiot, in Cross Days he's perfectly aware of what he's doing to Yuki.
- Used to Be a Sweet Kid: Until he was raped by Kei
- Wingding Eyes: In the ~Magical Heart Kokoro-chan~ OVA, he (along with Makoto) sports big shiny gold starbursts in their eyes in their ecstatic response to the arrival of the Anonymous Defence Service. Later, a naked Taisuke's eyes contain big white starbursts for Magical Heart, whom he sees in person for the first time.

Voiced by: Minami Kuribayashi (Minami), Nana Furuhara (Natsumi), Eri Saita (Kumi)
- Ascended Extra: Minami's given personal ending in Cross Days in which she takes advantage of the situation between Otome and Kotonoha to become Makoto's girlfriend.
- Big Bad Triumvirate: In the anime, at least; just about half of the worst things that happened in the anime were triggered by them, either directly or indirectly.
- The Bad Guy Wins: In the Cross Days ending, "Minami's Boyfriend".
- Clothing Damage: Along with Otome in the "Magical Heart Kokoro-Chan" OVA. This is probably the least Karma they got.
- Four-Way Sex: With Makoto in the anime.
- Good Eyes, Evil Eyes: Minami's eyes are pretty deceiving, aren't they?
- Girl Posse: The rare case where their Alpha Bitch is actually more sympathetic than them.
- Green-Eyed Monster: They harass Kotonoha following Otome's lead.
- Jerkasses: None of them have any redeeming qualities. At all.
- Karma Houdini: Big fucking time. Even more to Minami, in Cross Days.
- Shippers On Deck: For Otome and Makoto, though they aren't above sleeping with him while she is still involved with him in the anime. And that's without mentioning the blackmail Minami corners Makoto into in an ending of ''Cross Days''.
- Shoujo Hair: For a series with realistic hairstyle, Minami is quite standout.
Voiced by: Megu Ashiro (under the name "Aoi Kamitsuki" in the games)
- Annoying Younger Sibling: Sometimes, such as making demands on Kotonoha and Makoto's time in routes where Makoto is invited over to Kotonoha's house, but to her credit she's actually a less annoying example of this trope than usual; Kokoro adores Kotonoha immensely and only teases in good fun, and Kokoro gets worried sick if Kotonoha is sad or upset for any reason. Plus, Kokoro is strongly in favor of a relationship between Kotonoha and Makoto since Makoto makes Kotonoha happy.
- Bratty Half-Pint: At times. During Summer/Shiny Days, she incessantly complains about Setsuna's poor performance at her waitress job, even though she knows it's her first day.
- Children Are Innocent: In the anime and manga, at least.
- Whereas in visual novels, especially School Days and Summer/Shiny Days, she'll say things like "You aren't giving him any? I feel sorry for him" to her sister about Makoto, or encourages him to apply suncream on Kotonoha, or flirt with Makoto in front of her sister to the point she throws them off her nice boat overboard in a jealous fit.
- That said, in her "route" it's demonstrated that she doesn't really understand what her sister's supposed to be "giving". She asks Makoto to teach her but panics when he doesn't just hug her, ultimately knocking him out with a chunk of driftwood.
- Expy: Of Rin Sekihata from Pure Mail, a young girl love interest from another game of 0verflow with some elements from Misaki Washino from Large Pon Pon thrown in as well
- Magical Girl: In her own OVA, the infamous ~Magical Heart Kokoro-chan~.
- The Matchmaker: To her sister Kotonoha and Makoto. She crosses into matchmaker with a crush in some routes of Shiny/Summer Days.
- Older Than She Looks: Wait, is she really thirteen years old?!
- Talking to Herself: Shares a VA with Youko, Sekai's mother, in all adaptations, though they don't interact much, if at all, unless you count the Magical Heart Kokoro-chan OVA.
- Token Mini-Moe: In the Summer Days spin-off game, the 13-years-old Kokoro joins Setsuna in the Lolicon parade, and even gets two scenes where Makoto boinks (and in one, outright molestsnote ) her. The Japanese media was NOT amused.
- In Shiny Days, he may successfully force Kokoro to give him a blowjob. While the Japanese reluctantly let this pass, these scenes were removed from the JAST USA release in order to avoid legal controversy.
- It's worth noting that any sex scene with Kokoro would count as rape, given her age.
- Yandere: Played for laughs in the Valentine OVA.
Voiced by: Ryuusaku Chidiwa (anime), Takezou Koike (Cross Days)
A classmate of the group.
- Big Eater: He's known to attempt to set new records.
- The Faceless: His face is never shown, as it's always cut off by the top of the screen in every shot that he's in.
- Flat Character: His role in the original was more or less limited to being a walking height joke and to break his foot in order to give Makoto an excuse to join the student committee. He gains slightly more relevance in Cross Days, but not much.
- Hopeless Suitor: Towards Setsuna.
- The Voiceless: In Cross Days, he only ever speaks in various grunts. It doesn't stop the other characters from understanding him.
Summer Days Characters
Oruha Hashimoto and Noan Murayama
Two waitresses who worked alongside Setsuna in Summer Days/Shiny Days.
Voiced by: Maki Kobayashi (under the name "Mio Okawa" in the games)
A classmate of the main gang. She appears as a character in Summer Days and goes on to have a larger role in Cross Days, where she can become involved with Yuki or Makoto on certain routes.
- Adapted Out: In the manga version of Cross Days.
- Ascended Extra: First appeared as a minor character in Summer Days and later (depending on player choices) gets promoted to be one of the heroines of Cross Days and Island Days.
- The Bad Guy Wins: In one ending of Cross Days, Ai will successfully make Makoto her boyfriend while an unhappy Kotonoha is left alone. In two other endings, she will make Yuuki her boyfriend, devastating Roka.
- Bitch in Sheep's Clothing: She may be serene and soft-spoken, but she has no problem manipulating those around her if it means getting what she wants.
- Foil: She's basically what Sekai (and by extension, Otome) would be if without self-control and willing to destroy Makoto's relationship with Kotonoha for her own ends.
- Girls with Guns: In Island Days, she's shown with a Death Glare while holding a gun while looking at Otome, who seems to be crying on (presumably) Makoto's dead body.
- I Want My Beloved to Be Happy: Not normally, but played straight in Roka's true ending, where she decides to leave school and raise her baby alone, leaving Yuki and Makoto to their own lives.
- Ironic Name: Ai's name means love, but in "pure/giving love", not "possessive love".
- Meaningful Name: Will be this in Roka's true ending, in which she decides to give up on both Makoto and Yuki and let them be happy with their respective love interests.
Kazuha and Futaba Nijou
Voiced by: Megu Ashiro (Kazuha), Yayoi Sogetsu (Futaba) (under the names "Aoi Kamitsuki" and "Yayoi Kusatsuki", respectively in the games)
- The Cameo: They make a brief appearance in the anime finale. They also get a passing mention in one of Hikari's endings as new first-years in Sakakino High who want to try out Makoto in bed for themselves.
- Children Are Innocent: ...NOT!!
- Continuity Cameo: Kazuha wore the same outfit as the one her mother, Wakaba, wore in "Summer Radish Vacation".
- Family Theme Naming: Wakaba (若葉), Hanon (葉音), Kazuha (一葉), Futaba (二葉), Mitsuba (三葉), and Yotsuba (四葉).
- Fille Fatale: Futaba, the younger sister, is actually one. Fitting, considering Summer Days and Shiny Days have scenes with her and her father, Shun, getting it on. Kazuha, however, is more of a Shrinking Violet.
- Identical Twin ID Tag: Kazuha wears pink, while Futaba wears orange.
- Massive Numbered Siblings: Cross Days and Summer/Shiny Days revealed that they have an elder sister named Hanon, and several younger sisters named Mitsuba, Yotsuba, Shinaha, Shikuha, Kotoha, Komiha, and Konaha.
- Parental Incest: In several routes, Futaba has a sexual relationship with Shun, who is actually her biological father. One of their sex scenes with Makoto involve them trying to talk him out of a relationship with someone else in exchange for having his way with them.
- Sempai Kouhai: Their are Makoto's juniors, which is why they call him Senpai.
- Sibling Yin-Yang: Kazuha is a Shrinking Violet while Futaba is a Genki Girl and a Fille Fatale.
- Strong Family Resemblance: With their mother, Wakaba.
- Twin Threesome Fantasy: Provide this in the School Days universe. They are potential love interests in Summer Days and Shiny Days.
- Uncanny Family Resemblance: With their elder sister, Hanon.
Cross Days Characters
Voiced by: Mahiru Nakano
- Affectionate Nickname: Is called "Yuu-chan" by his sister's friends, which later lends into his alter ego's name. In the "Only You" ending, he also allows Makoto to keep calling him "Yuu" even after "Yuu" is exposed.
- All-Loving Hero: It becomes obvious that he's one when every girl in his harem loves him. Even if he cheats on them (which is unwillingly and unintentional), they won't kill him for cheating. They'll end their friendship, but other than that, he fits this as long as he doesn't cheat.
- Badass Bookworm: He's part of the school's library committee, and happens to know martial arts. Makoto knows the latter first-hand.
- Beware the Nice Ones: Not as extreme as Kotonoha, but don't underestimate him.
- Bishōnen: A more straightforward example.
- Break the Cutie: Taking Makoto's route leads him down the path of destruction as Taisuke blackmails and gang-bangs him. This obviously affects him, and depending on the ending, he might be stuck as a sex slave to Taisuke unless Makoto finds out and gets him out of it.
- The Cameo: In the HQ release of School Days, he is occasionally shown in the background.
- Expy: Of Negi Springfield from Mahou Sensei Negima!, since he looks a LOT like him.
- And when he crossdresses, he looks just like Mikuru Asahina! Justified, since Setsuna brought the wig from Cosplay Club.
- Despair Event Horizon: In the ending in Makoto's path where Makoto never finds out that Taisuke is blackmailing and gang-banging Yuki. Stuck in a really nasty situation, it really breaks him in the end knowing that Makoto won't save him. What makes it worse is that he can't tell anyone, because he doesn't want his sister finding out what he's been doing.
- Driven to Suicide: In the Cross Days manga, he walks in front of an oncoming train, but Roka bails him out.
- Dude Looks Like a Lady: according to Kyouichi in the visual novel.
- Failed a Spot Check: He somehow manages to completely miss what's happening between Kyouichi and the girls from his part-time job, and dismisses any of the events he sees as just his imagination.
- Gay Option: to Makoto within the entire School Days franchise.
- Heroes Want Redheads: In the routes with him, Makoto is determined to be with him, or at least his alter ego "Yuu".
- Heroic BSoD: In the manga, after Kotonoha shouts at him how cruel it was for him to deceive her and break her trust by crossdressing as Yu.
- Hopeless Suitor: He fell in love with Kotonoha, but she was in love with Makoto. He still tries to make her happy.
- Hypocrite: He calls Sekai out for getting between Makoto and Kotonoha, but then does the same thing if he pursues Makoto. Sekai doesn't come back to give him a taste of his own medicine, however.
- Karma Houdini: In one of the endings, he impregnates Ai and gets away with it, with the end result of Kotonoha killing her.
- Karmic Jackpot: In many of his endings, things always seem to go his way. The only time this doesn't apply is when his good deeds come back to bite him in the ass or if he pursues Makoto.
- Laser-Guided Karma: Appeared early in the storyline when he attempts to blackmail Sekai by taking a photo of her in a compromising position. He is punished by Setsuna and is forced to crossdress in the School Festival.
- Love Makes You Evil: His desire for Kotonoha to be happy leads him to attempt to murder and later blackmail Sekai in one path of the game.
- Loves My Alter Ego: Makoto is in love with "Yuu". This is what Yuuki wants at the beginning before he starts falling in love with Makoto. It's at this point that he begins to loathe his other self.
- Named After Somebody Famous: The Ashikaga Clan.
- Nice Guy: The major difference between him and Makoto.
- No Good Deed Goes Unpunished: In many of the bad endings, his main motivation for helping his friend Kotonoha ALWAYS comes back to bite him. In one bad ending, he is killed by her when he was trying to help her, and that's because she thinks that his alternate self Yu is taking her Makoto away — and in another ending, his sister Chie is killed instead. Also, when he tries to help the other girls, he's always caught in bad situations of cheating and is always blamed for it.
- Only Sane Man: For obvious reasons. He's the observer of Cross Days and can see what's going on with the love triangle and wonders why the hell no one is doing anything about it.
- He's also one of the few 0verflow protagonists who aren't related to Tomaru Sawagoe, which speaks volumes about his mental stability in itself.
- The Quiet One: By appearance, and he seems to be like this until he subverts it later when he punches Makoto.
- "The Reason You Suck" Speech: He gives one to Sekai when he thinks that she's the reason that Makoto is cheating on Kotonoha. Of course, the truth is far more complicated than he's aware of, but he wasn't necessarily wrong to call Sekai out on constantly picking at and meddling in Makoto's relationships.
- Red Oni, Blue Oni: The blue to Makoto's red.
- Screw Yourself: Played with. Yuuki is limber enough to perform fellatio on himself.
- Sempai Kouhai: always addresses Kyouichi as "sempai", as they're both on the library committee.
- Talk to the Fist: What does he do when he first meets Makoto? He punches him in the face, which surprises everyone.
- Third-Option Love Interest: The irony is that he would be the LEAST dysfunctional person Makoto could be with in the entire franchise.
- Tsundere: He doesn't seem to be one at all unless he takes Makoto's route, where it reveals he's a type B but warps into a mild type A when Makoto does something to piss him off... which is often.
- Well-Intentioned Extremist: He is so determined to convince Kotonoha of Makoto's darker side that he cross-dresses as a girl named Yu in order to draw Makoto's attention and expose his true nature. As with many of the well-intentioned actions in the series, this rarely ends well for him.
- Your Cheating Heart: In some endings, he messes up and ends up getting in situations where it looks like he's cheating. In one ending, he ends up with Ai instead of Roka... and he ends up regretting it.
Voiced by: Kaoru Mizuhara (under the name "Ren Minazuki" in the games)
Another student at the school who is introduced to Yuki by Chie and subsequently develops an attraction to him.
- Attempted Rape: In the Cross Days manga, she decides to confess her feelings to Yuki and Makoto then decides that he's going to rape her For the Lulz. Fortunately, Yuki is there to stop him.
- Berserk Button: Don't ever speak about her mother in a bad way about her being a hostess.
- The Cameo: In the HQ release of School Days, she makes a few appearances in the background, and becomes one of the girls involved in the video tape plot.
- Closer to Earth: When compared to Kotonoha and Sekai, Roka is much more sensible and, despite Yuki (apparently) cheating, doesn't resort to murder.
- Get a Hold of Yourself, Man!: In the manga, to Yuki when he's going through a nasty Heroic BSoD.
- Named After Somebody Famous: The Kitsuregawa Clan.
- Nice Girl: She stands out as one of the few characters who isn't hiding a nasty streak under a pleasant demeanour.
- Official Couple: With Yuki if he doesn't pursue Ai or Makoto. And in the Cross Days manga.
- Operation: Jealousy: In order to make Yuki jealous, she claims to be dating Makoto. This doesn't go as planned, however, as Yuki is already aware of Makoto and Kotonoha's relationship, and finding out that he is supposedly involved with Roka as well pushes him to become more involved in trying to stop Makoto's poor treatment of Kotonoha.
- Subverted in the manga, as it's Yuki himself who mistook Roka for being between Makoto and Kotonoha.
- Second Love: To Yuki after Kotonoha.
- Sempai Kouhai: always addresses and refers to Chie as her "sempai", as they're both on the basketball team.
- Slipknot Ponytail: When she rescued Yuki from being hit by a train in the manga. The much more tragic version appeared in the visual novel in Only Love and Courage Ending where Roka witnesses Yuki and Ai kissing in the middle of the street and tearfully bids farewell to him.
- Stock Shoujo Bullying Tactics: Roka used to be bullied by Otome, as her mother used to have an affair with Otome's father.
Voiced by: Mina Kurokawa (under the name "Mina Motogawa" in the games)
Yuki's older sister, who helps to instigate part of the plot of Cross Days by introducing Yuki to Roka.
- The Cameo: A much more active one than is the norm. In the anime, Chie is the one who films the students' sexual activities in the festival's "rest area" and then broadcasts it at the basketball party.
- Cool Big Sis: While she does tend to use Yuki as her personal gopher, it's obvious that she cares a lot about him, and will go out of her way to make sure he's alright.
- Driven by Envy: Her jealousy of Nanami probably explains why she shows the sex tape of Nanami and her boyfriend in the anime.
- Green-Eyed Monster: Towards Nanami due to the latter's natural athleticism.
- Heroic Sacrifice: One ending of Cross Days has her coming across Yuki's female school uniform and deducing who Yu is. Shortly afterward, Kotonoha confronts her and accuses her of being Yu. In order to protect Yuki, Chie confirms to Kotonoha that she is Yu. As the screen cuts to black, you can hear Kotonoha swing her crowbar...
- Named After Somebody Famous: The Ashikaga Clan.
- Pet the Dog: Sympathizes with Nanami when her boyfriend is revealed to be a cheater.
Ion Ishibashi and Youka Kira
Chie's friends and lackeys. Ion is the androgynous-looking one while Youka is the feminine one.

- Bitch in Sheep's Clothing: Not only did he cheat on Nanami behind her back, but he also forced sex on her sister, Yae.
- BrotherSister Incest: He holds feelings towards his sister, Kyoumi.
- Foreshadowing: Early in the first episode of Cross Days, he nonchalantly tells Yuuki, "I am a man of many faces."
- Karmic Death: He and Makoto are both killed by Kotonoha in one of the endings of Shiny Days, for forcing Kokoro into having sex with them.
- Otaku: Especially Eroge.

Voiced by: Futago Minazuki

- Karma Houdini: Along with Ion and Youka.
Voiced by: Natsumi Takamori (under the name "Toa Yukimura" in the games)
Kazuha and Futaba's older sister.
- Compensated Dating: Openly gloats in engaging in it to Makoto.
- Distaff Counterpart: To Makoto in regard to her Really Gets Around status.
- Femme Fatale: Hanon is very popular among the boys... and is also rumored to have sex with minors.
- Not Twin But Still Identical ID Tag: Hanon wears blue.
- Dramatic Irony: Despite her amorous and intensely sexual personal life, she never sleeps with Makoto, has no interest in him, and in fact never has sex onscreen either in Shiny Days, Cross Days or the other game she appears in, Strip Battle Days.
- Karma Houdini: Doesn't get punished for her Femme Fatale ways.
- The Mistress: She's one to Kyouichi.
- Theme Naming: Her name contains the kanji "葉" like her sisters. The "non" part is likely a pun for "none", in other word, zero.
- Really Gets Around: Her number of sexual partners is higher than Makoto, to say at least.
- Uncanny Family Resemblance: Taken Up to Eleven.
Voiced by: Yui Satou (Drama CD), Mariya Sumida (Cross Days, under the name "Mariya Kurada")
Hanon's friend, and a childhood friend of both Sekai and Setsuna.
- Hopeless Suitor: To Yuki.
- Foil: To Setsuna, who's more of Sekai's voice of reason.
- Idiot Hair: She has two of these, in fact. It foreshadows that she's even more "idiot" than Sekai.
- The Vamp: In one route, she attempts to seduce Yuki by performing a striptease. Fortunately, he just freaked out and ran away.
Ruka Imagawa, Natsuki Hozokawa, and Mugi Hatakeyama
Roka's trio of friends.

Shiny Days Characters
Voiced by: Madoka Nagano
The new heroine of Shiny Days and Setsuna's new roommate (thanks to the fact that she caused Setsuna's Wardrobe Malfunction) as well as a Shrine Priestess of Haramihama. She is the daughter of Shun and Natsuhi.
- The Gadfly: Setsuna's Wardrobe Malfunction may have been an accident, but she enjoys teasing both Makoto and Setsuna when the opportunity arises. She also leads Otome to believe that Setsuna made her her "love slave".
- Gag Boobs: That rivals even Kotonoha's.
- Heroic Bastard: She's the daughter of Shun and Natsuhi.
- Ill Girl: It's later revealed that she suffers a chronic illness.
- Meaningful Name: Her name means "to pray".
- Odd Name Out: The only one of Shun's daughters to not have a name related to number/time/space.
- The Ojou: is treated like one by the elderly parishioners of the Haramihama Shrine.
- Parental Abandonment: Natsuhi abandoned her at the shrine because she was underage when she was impregnated by Shun.
Voiced by: Maki Kobayashi
- Dark and Troubled Past: In Summer Radish Vacation it is revealed that she was once an aspiring child actress, but because her mother was repeatedly deceived, causing her to fall into massive debt, she was taken away and would have been sold as a sex slave if Shun hadn't rescued her.
- Meaningful Name: Her name means "summer day", a nod to the game she first appeared in, Summer Radish Vacation.
- Punny Name: Her full name is a pun on "NEVADA" (N.Ebata).
- Mommy Had A Good Reason For Abandoning You: Unlike Youko, Mai, and Wakaba, Natsuhi was only around ten at most when she was pregnant with Inori.
- Red Eyes, Take Warning: Played straight in her debut game. Averted in Shiny Days.
- She Is All Grown Up: When Shun first met her, she's the youngest love interest; now she is extremely beautiful.
- Teen Pregnancy: At the age of TWELVE, no less. Unfortunately, this is implied to possibly be the reason for Inori's chronic illness.
- The Vamp: Inori believed her to be this, and even called her an "Adulteress Woman".
- Weapon of Choice: A box cutter knife, which she used to stab Tomaru of all people.
Youko Saionji formerly Inou
Voiced by: Megu Ashiro
Sekai's mother and the former heroine of Summer Radish Vacation.
- Adaptation Dye-Job: From brown (Summer Radish) to deep brown (Summer Days). Considering the fact that she and Mai are family yet both pretend to not be related to each other as well as the fact that Shun and Natsuhi retained their original hair and eye color, it might be part of them to become new people or hide their family connection.
- Babies Ever After: In one ending of Shiny Days, Makoto impregnates her, Mai, and Setsuna, and the four of them then try to convince Sekai to become pregnant too.
- In one ending, she wanted to get pregnant to steal Makoto back from Kotonoha, but it's not clear whether she managed to, and even if she did, it didn't work.
- BrotherSister Incest: Her ex-lover, Shun Hazama, is in fact her half-brother, and she held feelings for her brother Ayumu in the past. This trope is also played if Makoto pursues her.
- Clingy Jealous Girl: In some routes, she takes Makoto's womanizing ways... badly. Averted in harem ends. Played for laughs, when Makoto walks into Radish with Karen, she orders one of the waitresses to bring her the "largest knife in the restaurant". The ending picture shows the knife stuck in the wall.
- Ephebophile: Apparently Makoto isn't the first underage lover she's taken. Youko seems to have a thing for underage boys her daughter's age, which says disturbing things about her by itself, but Sekai is aware of it enough to make it clear she doesn't want a stepdad her age and Youko even jokes about it to Sekai, much to the latter's displeasure.
- Family Theme Naming: Youko, her sister Kagura, and her niece Mai all have names related to Dance.
- Generation Xerox: Whether intentionally or not she basically tries to turn her daughter Sekai into a generational clone of herself. Going so far that in various routes she forces Sekai into teen pregnancy, at a time when Sekai is the exact age Youko herself was when she became pregnant with Sekai.
- Also she nearly always makes sure, that Makoto impregnates both of them, making all Youko's and Sekai's endings in Summer/Shiny Days, with exception of one, oyakodons.
- Love Hurts: She still resents Shun to this day for not loving only her. Dialogue in School Days pretty much confirmed that she won't ever let him come back into her or Sekai's life again.
- Older Than They Look: This is Youko when she was in her teenage years.◊ 15 YEARS AGO.
- Parental Incest: In Summer Days and Shiny Days, you can score a threesome with her and Sekai.
- Parents as People: It's hinted she's been raising Sekai all alone, and despite caring for her, she can't always be there for her.
- Promoted to Love Interest: She literally takes over her daughter's place and becomes one of the most significant possible love interests for Makoto in Summer/Shiny Days.
- Shipper on Deck: Is this for Sekai and Makoto if you pursue Sekai's path in School Days and succeeding games. In Summer Days and Shiny Days, you can end up with Youko ,but if you play your cards right, Makoto scores a threesome with Sekai and Youko, who agrees to share her lover with her daughter. And she, of ALL people, salvages Sekai and Makoto's relationship in one of the game paths, leading to one of Sekai's best endings.
- Strong Family Resemblance: Does resemble her mother, Moegi, especially in terms of personality.
- Talking to Herself: Shares a VA with Kokoro, Kotonoha's younger sister, and Kazuha in all adaptations, though they don't interact much, if at all, unless you count the Magical Heart Kokoro-chan OVA.
- Teen Pregnancy: In one route, she mentions that she was about the same age as Sekai when she became a mother, which is indeed true if you play Summer Radish Vacation.
- Yandere: Played for laughs like Kokoro in the Valentine OVA.
Voiced by: Shiho Hisajima
- Absolute Cleavage: Her normal attire in Summer/Shiny Days shows a really large amount of cleavage. Her red dress in Cross Days averts this trope.
- Babies Ever After: Makoto impregnates her in one ending of Summer Days and Shiny Days.
- Buxom Is Better: Let's just say that once you meet Manami, it's rather apparent where Kotonoha gets her own endowments from. She has the largest bust size of all the female characters in School Days and its universe at 122 cm.
- Clingy Jealous Girl: In some routes, at least. She scares away the Nijou twins who wanted to visit Makoto to seduce him, in order to have sex with him herself, and proclaims she won't share him with anyone, even her daughters. Averted in routes where she DOES share him with her daughters.
- Irony: Criticizes Youko for having stripperiffic outfits as her restaurant's waitress uniform... despite wearing one as well. Oops.
Mai Kiyoura formerly Inou
Voiced by: Moe Natsumi
- Amicably Divorced: With Shun.
- Adaptation Dye-Job: From brown (Summer Radish) to greenish-black (Summer Days).
- Babies Ever After: In one ending of Shiny Days, Makoto impregnates her, Youko, and Setsuna, and the four of them then try to convince Sekai to become pregnant too...
- Childhood Marriage Promise: With Shun, which Mai took very seriously.
- Divorce Is Temporary: It is possible for Mai to get back together with Shun in certain routes in Shiny Days. Natsuhi even invokes this trope while teasing Shun.
- Incest Is Relative: Her ex-husband is Shun Hazama, who is in fact her half-brother/uncle. Again, this trope is played straight if Makoto pursues her.
- Official Couple: Used to be one with Shun in Summer Radish Vacation.
- Victorious Childhood Friend: Played straight and subverted. Mai does get together with Shun for some time until she discovered Shun with other girls. However, it's possible for her to get back with him in certain routes if Makoto didn't get involved with her.
Voiced by: Hirosumi Higuchi
The main character from the Summer Radish Vacation! game. Eldest son of Tomaru and Hatsuka Hazama. Father of Sekai, Setsuna, Nijou Girls, Inori, and possibly Roka.
- All Men Are Perverts: Cannot withstand the sight of Futaba (his daughter with Wakaba) stripping in front of him, and so...
- BrotherSister Incest: More than half of his lovers have been his half-sisters, and he also had sex with his full sister, Toki Hazama. Shun may not be nearly as callous as his father, but he definitely inherited his sexual hangups.
- Parental Incest: Also, had a child with his own mother.
- Disappeared Dad: To all of his children more or less. Despite the fact that he is aware of all of his children and knows who they are, he hasn't seen most of the them in over a decade. Sekai and the Nijou sisters aren't even aware that he is their father, though they know who he is, and although he has tried to be a father figure to the Nijou girls, this backfired when he ended up in a relationship with Futaba. Inori had no knowledge of Shun and doesn't even realize he's her father till certain routes in Shiny Days, after which he can adopt her, and Roka Kitsuregawa has not made any awareness of her parentage obvious either, though that could change. Setsuna is the only child of his who is known to be fully aware of the fact that he is in fact her dad, probably because he married her mother.
- Hero of Another Story: Of Summer Radish Vacation.
- Heroic Bastard: Hatsuka never legally married Tomaru, and so this trope is in effect.
- Hypocrite: He despises Tomaru for his womanizing ways, but his own womanizing is so bad it lost him his job as manager of Radish due to sexual harassment and caused two of his lovers to abandon him.
- Hypocrite Has a Point: And yet he is one of the few people who is actively foiling Tomaru's plans.
- Earn Your Happy Ending: There is exactly one route in Shiny Days that Shun gets to be with Mai and Setsuna once more.
- Family Theme Naming: His given name Shun (瞬) can means moment. Setsuna also means moment.
- He Who Must Not Be Seen: Like Tomaru, he is only mentioned and/or implied through little details. Finally makes an appearance in Summer Days.
- Knight in Shining Armor: In a sense, he is one to Kagura Inou, as he rescued her from Tomaru. He's one to Natsuhi too, which he proceeds to remind her about in Inori's route.
- Luke, You Are My Father: He's Setsuna's father and Makoto's older half-brother.
- Only Sane Man: The only one of Tomaru's children who actively tries to foil him. However, he still lets his libido get the best of him at times.
- Tall, Dark, and Handsome: Described as very good looking by several different characters and is just as much of a Chick Magnet as Makoto.
- Well-Intentioned Extremist: His reasons for having sex with the girls along with his sister and mother is because he wants to protect them from Tomaru's clutches.
- What the Hell, Hero?: Gave one to his mother for attempting to get back with Tomaru years after he had already abandoned her best friend, Kagura. The breakdown in relations caused him to leave home and go work for Kagura for a summer. This sets up the events of Summer Radish Vacation, and him meeting Youko and Mai, his future lovers.
Voiced by: Emi Uwagawa
Makoto's little sister, who lives separately from him since their parents are divorced, so Itaru only gets to visit Makoto infrequently. You don't get to see her at all in School Days unless you take a couple of very specific paths. She gets much more screentime in Summer Days since she stops by for a visit in that game's first episode.
- Alliterative Name: Itaru Itou
- Alternate Character Reading: Both Itaru and Tomaru are alternate readings of the same kanji (止) that both have as their given name.
- Annoying Younger Sibling: Averted in School Days and subverted in Summer Days. Itaru loves big brother Makoto to pieces and her presence does not cause any problems in School Days, averting the trope. There's some childish behavior she exhibits sometimes in Summer Days (pouting over a lost opportunity for a parfait, for example, or pounding on the door if Makoto doesn't ring Setsuna's doorbell out of indecisiveness), but depending on how Makoto handles it, he can actually use the opportunity to score free brownie points with Setsuna, subverting the trope.
- Cheerful Child: Very much so, and is beloved by the characters who meet her.
- Children Are Innocent: Does not know about her brother's dark side. And it's better that she does not.
- Morality Pet: to Makoto.
- Pet the Dog: Sort of. Makoto's usually indecisive and can even be played as a jerk who plays around with others' feelings, but he comes off as a saint when Itaru's around. However, she doesn't show up often enough in School Days for this trope to take full effect. It's really played straighter in Summer Days, where Itaru stays for a longer visit and the responsibility of looking after Itaru makes Makoto look more mature and reliable.
- Satellite Character: Itaru is extremely adorable and nice and lovable, but admittedly her character can be summed up as "Makoto's little sister."
- Strong Family Resemblance: Take away her pigtails and she looks exactly like a younger Makoto.
- Token Mini-Moe: Subverted; unlike Kokoro in Summer Days, Itaru does not have a sex scene. She does have a bath scene with her big brother Makoto in School Days if you take the very rare paths where she even shows up in the first place, but you can't see anything objectionable (the water is exactly at the height of Itaru's nipples, covering them up) and Itaru spends the scene fishing for a rubber ducky, as innocent as it gets. There's also one line by Itaru that she might like to be Makoto's bride, but unlike how some visual novels would handle it, it's not taken any more seriously than an extremely young girl who hasn't quite figured out that you don't love a boyfriend/fiancee/husband in the same manner that you would a family member.

Otome's younger sister. She appears in Summer Days and Shiny Days.
- Age-Inappropriate Dress: Her Island Days' outfit◊ focused a lot on her big breasts and thighs.
- Annoying Younger Sibling: So Otome says.
- Sister-Sister Incest: One of the H-scenes in Summer Days involves her and Otome having a threesome with Makoto. The reason this counts as "incest" rather than just a regular threesome is because partway through the scene Karen starts pleasuring her sister Otome, not just Makoto.
- Big Breast Pride: Though Otome wishes she had D-Cup Distress instead.
- Buxom Is Better: Her bust is bigger than Otome's, and Karen is very much aware of this.
- The Cameo: She makes a brief appearance in the anime finale.
- Cheerful Child: Also a Genki Girl.
- Children Are Innocent: Averted, as Karen is one of the girls Makoto can end up with in Summer Days.
- Fille Fatale: Sometimes Played for Laughs, since Karen is a Genki Girl who loves to tease her older sister Otome about the latter's crush on Makoto.
- Girlish Pigtails: Similar to Itaru's.
- Manipulative Bitch: She's worse than Kotonoha! Where Kotonoha tries using her attractive body to win Makoto's affections, Karen actively deceives him to get into his pants. To make matters worse, Makoto falls for it.
- Meaningful Name: The Kanji for her name means "sweet, cute, lovely".
- Ironic Name: In terms of western meaning, "pure" isn't the most exact thing that can be used describe Karen.
- Sempai Kouhai: Like the Nijou twins, Karen calls Makoto Senpai.
- Shotgun Wedding: Parodied in Summer/Shiny Days with Makoto.
- Shipper on Deck: Is this for Otome. If you aim for Karen's route, though, she feels slightly guilty, but you can score a threesome with both sisters if you play your cards right.
- Sibling Yin-Yang: If you take into account Otome's shy crush and Karen's straightforward methods of trying to win over Makoto, they are this.
Voiced by: Emi Motoi
Makoto and Itaru's mother who works as a nurse.
- Hospital Hottie: She works as a nurse.
- Older Than They Look: There is some indication that she's roughly around her 50s.
- Only Sane Woman: Seems to be the most sane mother of the Overflow Protagonists.
- Averted in Strip Battle Days 2 where she has sex with Makoto and gets pregnant. On the other hand, as that takes place in an alternate universe where the outcomes of rock-paper-scissors matches are considered morally and legally binding, that version of Moeko is starting from a lower level of sanity than her canon self.
- Parents as People: Same deal as Youko, Moeko is always busy as a nurse to keep her son right in check.
- Strong Family Resemblance: To both Makoto and Itaru.
- Unwitting Pawn: Possibly. Moeko had been involved with Tomaru's adultery crimes far longer than one can imagine, having started from around the time that she helped Kagura Inou give birth to Hajime.
