[[folder:Keiichi Maebara]]
!!"[[TheCharmer Magician of Words]]" Keiichi Maebara
!!!Voiced by: Creator/SoichiroHoshi (JP), Creator/GrantGeorge (EN)
The main protagonist in the "question" arcs. The son of a famous artist, his family recently moved to Hinamizawa after an unfortunate event involving him in their hometown. His charisma and remarkable talent for speechmaking allow him to easily make new friends and become popular in the village.

The first arc, Onikakushi-hen (Spirited Away by the Demon chapter), is focused on him.
* AdaptationDyeJob: Eye variation. The anime and the Mahjong game are the only continuities in the series that display him with purple eyes, though occasionally a manga color will show him with purple.
* AllLovingHero: In the later arcs.
* AllMenArePerverts: Strong believer in this and proud of it, even if he himself is more chivalrous about it. This applies more to his anime counterpart than to his character in the visual novel.
* AmnesiacDissonance: "[[MyGodWhatHaveIDone What have I done?]] [[spoiler:I killed Rena and Mion!]]"
* TheAtoner: In ''Tsumihoroboshi-hen'' ("Atonement Chapter"), naturally.
* BadLiar: Whenever he does anything that will get him in loads of trouble, he will act very guilty and his lies are horrendous, especialy in ''Watanagashi-Hen'' and ''Tatarigoroshi-hen''.
** However, in all other cases, he is an absolute ''god'' at getting people to believe crap that he makes up.
* BatterUp: His go-to weapon is Satoshi's baseball bat.
* BeCarefulWhatYouWishFor: Keiichi gets smacked around with this {{Aesop}} in ''Tatarigoroshi-hen''. Create a perfect murder that can't be discovered and verified? Fine. Except it can't even be verified by you. [[IWishedYouWereDead Wish people who are making your perfect murder more difficult were dead]]? Fine. Insanity Ensues.
* BerserkerTears: He cries his heart out while killing his two best friends in what he ''thinks'' is self-defense. [[RRatedOpening This is pretty much the first thing you see in the series.]]
* BigBrotherInstinct: An incredibly dark twist on it.
* BigFancyHouse: Called "the Maebara Mansion" by the villagers, though about 2/3 of it is taken up by his father's art studio.
* BishieSparkle: Used in liberal amounts.
* {{Bishonen}}: He's noticeably pretty and even [[BishieSparkle sparkles]] on various occasions.
* BookDumb: Played with. In the first episode, he's seen helping Rena and Mion to understand their work, and in ''Tatarigoroshi-hen'', it's shown that part of the reason he was teased so much in his hometown was because he was doing too well in school. He just has a different learning style.
* BreakTheCutie: Tends to "snap" rather than "break", though.
%%* BrokenAce
* ButThouMust: In the [=PS2=]-only adaptation, Matsuri, there actually is a way for Keiichi to offer the doll to Mion before [[spoiler:''Minagoroshi-hen'']]. She still refuses, and you can unlock Watanagashi-hen through that route as well, though instead of flaying you for not giving the doll to Mion, it instead flays you for offering it to her when there's no way she feels she can accept it without embarrassing herself. You just cannot win.
* ButtMonkey: The other members of the club seem to take glee in pulling pranks and embarrassing him even outside their usual punishment games. Especially Satoko who spends hours designing and setting up traps just to humiliate him and Mion whose [[spoiler:tabasco sauce/]]needle filled ohagi convinced him they were trying to kill him. In fairness if your friends treated you like they do [[spoiler:and you were suffering from a disease that causes ''extreme'' paranoia]], you would have probably come to the same conclusion.
** In ''Kai,'' he is horrified when [[NewMeat Hanyu]] joins the club... and everyone still decides to haze him. Apparently club ranking is not determined by how long you've been in it.
** In ''Watanagashi-hen'', the earlier chapters (especially at the game store) are an entire HumiliationConga of this, mostly done by Mion. This may have been a factor in him giving the prize doll to Rena instead of her, kicking the story into high gear.
* BuxomIsBetter: Averted in the manga[[note]]Onikakushi, Volume 1, Chapter 3, Page 16[[/note]]. He tells Mion her boobs are too big and that he prefers Rena's more average size. Then again, he may have said that merely to tease the both of them.
** Strangely, it's the other way around in the VN: after criticizing Mion for skipping breakfast and praising Rena for eating hers, he encourages Rena to grow curvier, not flat like Mion. Probably a subversion of the trope since, as Mion is visibly ''not'' flat, Keiichi is definitely teasing.
* CharacterExaggeration: He's notably more HotBlooded and [[AllMenArePerverts a pretty big pervert]] in the anime adaptation. In the original sound novels, he's more of a rather generic, but good-natured NiceGuy who only occasionally acts hot-blooded ([[MundaneMadeAwesome typically only during club games]]) and perverted, and often even chastises some of the ''girls'' (like Mion) for acting like a pervert. He's also much less subtle and introspective in the anime, however this can easily be justified in that it's hard to get across an introspective internal monologue in an animated format, as opposed to a sound novel format.
* TheCharmer: Called The Magician of Words for his supreme charisma and talent in bullshitting.
* ChickMagnet: Though it can also work against him. [[spoiler:Shion was attracted to him in Watanagashi/Meakashi and it's one of the things that set her off since she didn't want him to replace Satoshi in her heart.]] Either way, he has Mion, probably Rena and maybe Satoko based on one of her last lines in Tatarigoroshi as well as general popularity. Furthermore, the manga Kataribanashi-hen (drawn by various artists with the approval of [=Ryukishi07=]) suggests that Rika likes him as well.
* ChivalrousPervert: Takes pride in being a pervert, but he cares very much for his friends.
* CityMouse: A nicer example than most, but he moved to Hinamizawa from the city. He sees the village as a huge improvement over his past life there once he gets used to it.
* ConvenientlySeated: He always sits in the second-to-last row, along the windows.
* DarkAndTroubledPast: His family moved to a little town in the middle of nowhere for a reason...
* DecoyProtagonist: Though he remains an important character, in ''Kai'' it's revealed that the real main protagonist of the story [[spoiler:is Rika.]]
* {{Determinator}}: No matter what, Keiichi does not give up.
* DidIJustSayThatOutLoud: In the sound novel, he wonders why the other club members can read his wacky thoughts like an open book when he is nervous. When the narration switches to Rena in ''Tsumihoroboshi'', it turns out it's because he doesn't just think them.
* DraggedIntoDrag: This happens to Keiichi a few different times as the result of punishment games. Usually it's a {{Meido}} costume.
* EvenTheGuysWantHim: Has an entire army of loyal fanboys that call him Comrade K because he helped them embrace that AllMenArePerverts.
* {{Fanservice}}: The first episode of ''Higurashi no Naku Koro ni Rei''. That's all.
* FeaturelessProtagonist: In the sound novels he was this, but only for the first half of the series, after which he gets character sprites like the other major characters.
* {{Foil}}: In sharp contrast to Rika's fatalism, Keiichi is a {{Determinator}} who won't believe fate decides everything. Also serves as this towards Mion and Rena, being less calm than them.
* {{Foreshadowing}}: In the sound novel, Keiichi hears [[spoiler:Hanyu's voice apologizing]] as soon as just after the title screen of the first chapter. [[spoiler:Since he has been away from the village for a few days, he has already started to develop the syndrome.]] At that moment though, he's half-asleep and thinks it's just a girl apologizing to someone.
** This later counts as FridgeBrilliance, too. Annoyed with the unknown girl's constant apologies, he thinks that whoever she's apologizing to should just forgive her already, as she clearly feels guilty over what she did. ''Higurashi'' is the story of [[spoiler:how Hanyu and Rika forgive themselves for failing the GroundhogDayLoop so many times, and are thus able to move on to the future.]]
* GivingSomeoneThePointerFinger: In the VN, Keiichi does this during the bento competition (at least in the CG), when he basically turns it into [[VisualNovel/PhoenixWrightAceAttorney Phoenix Wright]]: Lunchtime Edition.
* TheHeart: [[spoiler:When he's not a VillainProtagonist.]] Rika and Hanyu comment in the manga that he is the 'piece' that brings change to Hinamizawa. Because Hinamizawa is a village so traditionalist and unchanging that its people have begun to stagnate, it is very important that he comes and stirs up their preconceptions - in particular, changing the ostracising attitude that many have towards the Houjou family. In Matsuribayashi-hen [[spoiler:Rika and Hanyu are shown to takes measures to ensure Keiichi moves to Hinamizawa.]]
* HeKnowsTooMuch: Keiichi spends most of Onikakushi-hen being harrassed by Rena and Mion because of this. [[spoiler:Or so he thinks.]]
* TheHero: Takes up the role in ''Tsumihoroboshi'' and ''Minagoroshi.'' In two of the prior three arcs [[spoiler:he's actually a VillainProtagonist.]]
* HopeBringer: His presence is what gives hope to [[spoiler:Rika]], since according to her he didn't move to Hinamizawa in two unseen timelines and these were "sad and doomed worlds".
* HotBlooded: Keiichi just about oozes passion, no matter what he's talking about. For just one example, see his speech [[https://www.youtube.com/watch?v=lLXaNGafL34 as K]].
* IDontWantToRuinOurFriendship: In ''Kira,'' this is Keiichi's response to the romantic shenanigans going on. More justified than most examples, in that the story fully establishes that he knows how wonderful it is to have TrueCompanions that one can trust like family, and he doesn't want to screw that up by causing jealousy between anyone.
* ImageSong: "Cool ni Nare". Also has a [[CrowningMomentOfFunny rather humorous]] rap with Ooishi… at least [[SanitySlippage until]] [[DrivenToSuicide the end]].
* IndyPloy: Along with [[PsychologicalCombat fast talking]], this is a characteristic distinct to Keiichi, and what his club mates admire and rely on him for.
* IntelligenceEqualsIsolation: In the Tatarigoroshi-hen arc, it's revealed in a flashback that he was bullied for being too smart. As a result, he tended to be isolated from the class and even had a dead rat placed on his desk as a result. You know the rest, but this leads him to becoming BookDumb. He recognized that moving to Hinamizawa meant he could change himself, and jumped on the chance - partly because he was afraid of becoming entirely isolated from emotion again, to the extent of hurting others for fun, and partly because his 'past life' was joyless and ultimately unfulfilling. The fact that his current personality - social, warm-hearted, and TheHeart - is entirely opposite to his old one is probably not a coincidence.
* InterruptedSuicide: The full ending of Tatarigoroshi-hen.
* IWishedYouWereDead: ''Tatarigoroshi-hen''.
* JackOfAllStats: In Higurashi Daybreak, he's this along with Nata Rena. He has decent running speed, plausible defence, great melee range and powerful range attacks that cover quite a distance. However, all three of his weapons lean slightly towards being a ranged moevest of varying styles, with the Baseball Bat being more BoringButPractical , the golf clubs going for more damage at expense of less control and the shovel has an emphasis on wide-spread keep-away tactics.
* KickTheSonOfABitch: What he does to [[AssholeVictim Teppei]] in the 3rd novel and the [=PS2=] "Exorcism Chapter".
* KnightTemplarBigBrother: In Tatarigoroshi, once he learns about Satoko's plight, he takes ''extreme'' measures to put it to an end.
* TheLeader: Type IV - Charismatic. His charisma and force of personality are essential to bringing everyone together as a group. [[spoiler:Rika]] mentions that [[spoiler: there have been worlds where Keiichi never moved to Hinamizawa - all of them doomed to failure.]]
* LethalChef: Screwing up some basic stuff like Miso soup or rice is a thing. Almost setting fire to your house while cooking vegetables is [[EpicFail Homer Simpson level]].
* LonersAreFreaks: Once, he got bored of studying and [[spoiler:decided to shoot down random kids with a BB gun. He stopped and turned himself in because he hit a little girl in the eye.]]
* LoveEpiphany: The first part of his narration is a very dark example towards Rena, who he has just murdered in a crazed fury. It should be noted, though, that he may mean platonic love rather than romantic love. Also crosses over with EtTuBrute and WasItAllALie.
* ManlyTears: In the Atonement Arc.
* MyGreatestFailure: The first is that he realized what horrible things he had been doing back in his old life [[spoiler:when he was shooting at children with a BB gun. He later confesses this to his friends, which leads him to remember Onikakushi and having an even ''worse'' case.]] Both of these occur in Tsumihoroboshi, or Atonement Chapter.
* NaiveNewcomer: ''Onikakushi'' might be a {{Deconstruction}}. The fact that Keiichi knows nothing about Hinamizawa or important past events and feels like an outsider, is a major cause of his growing paranoia and suspicion toward his new friends; and serves to lure the equally clueless reader as well.
* NiceGuy: More so in the sound novels.
* ObliviousToLove: Can't seem to catch on to Mion and Rena's attraction to him. Taken UpToEleven in ''Musubienishi-hen''.
** Actually, in the latter it isn't so much that he doesn't realize, rather that he doesn't want to choose.
* IntergenerationalFriendship: In ''Minagoroshi-hen'', with Ooishi. Doubles as a rather OddFriendship, especially considering their cold relationship in the previous arcs.
* OneDialogueTwoConversations: In ''Onikakushi'', a few days after he ate the Ohagi with [[spoiler:the "needle" (actually tabasco sauce) inside]], he screams at Mion, saying that her ohagi was so good he almost died. She answers, almost crying, that it was just a little prank. It's obvious in this exchange that they are ''not'' talking about the same thing.
* TheOneGuy: He is the only guy in a club full of females, but most of them aren't interested in him, and even the ones that are take it more as 'Hey, let's gang up on the new guy!' rather than, 'Oh, we should abandon our friendships to fight over him.'
* OnlySaneMan: Seems so at first when he's his normal self.
* PsychologicalHorror: The horror from his arc ''Onikakushi-hen'' comes more from paranoia and fear rather than blood and gore.
* RedOniBlueOni: The "furious red flame" to Rena's "silent blue flame". Later plays the same role, but to Rika instead. Also has this relationship (same role, but to a lesser extent) to Mion.
* RousingSpeech: An expert on these. Mion goes so far as to call him a master of words. Becomes a plot point in ''Minagoroshi-hen''.
* RunningGag: In the visual novel, it's a running gag to have Keiichi imagine something really outlandish and then have everyone respond specifically to the outlandish thing he was thinking. Everyone else says that you can tell exactly what he's thinking by his face.
* SmarterThanYouLook: He's actually among the most intelligent people in the main cast. Shion in particular doesn't think much of his brains.
* SoleSurvivor: In Tatarigoroshi-hen, he is the only person living in Hinamizawa who survives the Great Hinamizawa Gas Disaster. He does die eventually, though. Just not from that.
* StockShonenHero: Keiichi is a HotBlooded {{Determinator}} and [[spoiler:in the arcs he isn't a VillainProtagonist]] he firmly believes in ThePowerOfFriendship and will do anything to try and save his friends. Even though he isn't the main character, Keiichi still acts as TheHeart and inspires to ''real'' main character to not give up.
* StupidSexyFriend: Often feels this way towards...well, every teenager in the club. He's not interested in dating yet, but the fact that all of them are hot chicks makes such things as swimming expeditions awkward.
* SupportingProtagonist: [[spoiler:The story is really about Rika. However, he ''is'' the character that inspires her the most.]]
* SuspiciouslySimilarSubstitute: Subverted. In-universe his similarities to Satoshi are often pointed out, but it turns out the only they are just the similarities others want to perceive... [[spoiler:until the syndrome strikes, and they act OutOfCharacter in almost identical ways.]]
* SympatheticMurderer: In ''Tatarigoroshi.''
* ThinkingTic: Rena once remarked that when Keiichi is thinking deeply about something stupid, he will often bend his head backwards and start [[DidIJustSayThatOutLoud speaking his thoughts without realizing it.]]
* TooDumbToLive: So your friend has just admitted to committing multiple murders, then suddenly decides she wants to go on a walk with you alone? Sure. Then said friend asks you if you want to see her sister, whom she has kidnapped? No problem. She leads you into a TortureCellar, admits to killing two of your closest friends, torturing her own sister, and said sister screams bloody murder at the sight of her? Everything's absolutely fine. Somehow he still manages to act surprised when he gets knocked out and wakes up strapped to one of the torture devices. Through dumb luck, he survives, and still trusts this friend enough to step out of his house and speak with her when she drops by in the middle of the night. At this point, he ''deserves'' to die.
* UnreliableNarrator: In many of the early arcs, especially Onikakushi-hen.
* UnscrupulousHero: A pretty dark take on this in Tatarigoroshi-hen.
* VillainProtagonist: Only in [[spoiler:''Onikakushi''. Not that he, or the reader, are aware of that.]]
* VitriolicBestBuds: He and Satoko - except in Tatarigoroshi-hen, where Keiichi tries to act more like Satoshi - constantly snipe at each other, and it's very clear that their friendship is built on this dynamic.
* WeaponOfChoice: Satoshi's baseball bat.
* WhatTheHellHero: When Rena finds out some things about his past, she calls him on this. Also the catalyst for the Atonement Chapter having the name it has.
* WorthyOpponent: Partly why Mion likes him so much. They're not equals in skill, but they share a competitive, easily riled spirit that no one else in the club has.
* WouldHitAGirl: If said girl set up a combo-trap for him on his first day at his new school, yes he would. Not to mention [[spoiler:hitting a girl in the eye with a BB gun in his backstory.]]
* YouCanAlwaysTellALiar: In one scene in Taraimawashi-hen, Rena claims that when Keiichi lies, his nose twitches.

[[folder:Rena Ryugu]]
!!"[[ImTakingHerHomeWithMe Cute Mode]]" Rena Ryugu
!!!Voiced by: Creator/MaiNakahara (JP), Creator/MelaLee (EN)
A girl who returned from Ibaraki to Hinamizawa one year ago, and she is in same grade level as Keiichi. She has an obsession with things she perceives as cute, whether they're actually adorable or butt-ugly. Every now and then, she goes treasure hunting in the town's trash heap, searching for "cute" things to collect, and upon finding something "cute", it's difficult to stop her from taking it home. Despite this disarming trait, Rena is shown to be amazingly observant and perceptive about the things around her. According to Mion, while Rena might seem cute herself, people should be careful not to anger her as she becomes quite scary. She is especially sensitive about the topic of Oyashiro-sama, who she fears will curse her for leaving Hinamizawa.

The sixth arc, Tsumihorobishi-hen (Atonement chapter), is focused on her.
* ActionGirl: Very violent behind her usual cute self.
* AgentMulder: She believes whole-heartedly in Oyashiro-sama and the legends surrounding the god, especially the curse. Questioning her beliefs will make her angry and quite unstable.
* AlliterativeName: '''R'''ena '''R'''yugu.
* AnAxToGrind: Alongside her signature "cleaver", she's even strong enough to wield a ''great axe'' to brutal effect.
* ArmorPiercingSlap: On Keiichi to push him to apologize to Mion in ''Watanagashi''. It kind of feels like a mother scolding her kid.
* AttackOfTheFiftyFootWhatever: As a BackgroundBoss in the "Strolling Rika" mini-game.
* AttemptedRape: She may or may not have been on the receiving end of this, as [[spoiler: she was affected by Hinamizawa syndrome at the time and possibly only ''thought'' this is what her male classmates were attempting to do, and she nearly kills them as a result. But because the boys refuse to talk about Rena's attack, even to the police, they really might have been trying.]]
* AxCrazy: [[spoiler: Only in Tsumihoroboshi-hen and Exorcism]], though she's someone infamous for being this to those who aren't familiar with the series.
* BadassAdorable: Cute, but with the biggest 'inner demon'.
* BerserkButton: Don't mock her belief in Oyashiro-sama.
** Also, being called "Reina-chan" by Rina [[spoiler:in the same way as her hated mother.]] In this case though, the problem is not so much the button than the ''person'' who presses it.
%%* BerserkerRage
* TheBigGirl: Don't underestimate Rena because of her size. She looks [[CuteBruiser cute]], but [[BewareTheNiceOnes get her mad]] and she'll have [[AnAxeToGrind a cleaver to grind with you]].
* BreakTheCutie: Like Keiichi, snaps more often than breaks.
* CatchPhrase: [[ImTakingHerHomeWithMe "HAU~! OMOCHIKAERII!"]]
* TheConfidant: To Mion in ''Watanagashi''. She also helps Keiichi realize that he hurt Mion's feelings, so it may be a indirect case of PlayingCyrano.
* CovertPervert: [[ItMakesSenseInContext She blushes when she hears Keiichi say that it's soo hot his crotch is getting sweaty to both her & Satoko in the VN.]]
** Also, in ''Rei'', she’s a little ''too'' eager to [[ItMakesSenseInContext strip Keichii of his swim trunks...]]
* CryCute: At the end of the Atonement arc. Also counts as a CryIntoChest.
* CryLaughing: In ''Tsumihoroboshi-hen'', she spends a long monologue insisting that she had no other choice than killing [[spoiler:Teppei and Rina]] who were swindling her father, and that telling her friends would have been useless. Then she mocks them and starts laughing out loudly before bursting into tears, as she understands fully well that this may not have been the right choice.
* TheCuckoolanderWasRight: In ''Tsumihoroboshi'', she may not be all there but there are a few things that she actually gets ''right''. [[spoiler:Notably the Okonogi gardeners being a fake society hiding secret agents, the fact the Hinamizawa Syndrome is being researched at the Irie Clinic, or the fact that there is ''some kind'' of relationship between said research and the mysterious deaths.]] Of course she is completely off the mark about all the rest, but that's still ironic.
** Well... at least until ''Hou'', when [[spoiler: it's revealed that one of the mysterious viruses ''is'' the work of an alien. Une's, that is. It wasn't Hinamizawa Syndrome, but it was close.]]
* CuteAndPsycho: She supplies the Page Image. [[spoiler:Though in truth it is a subversion. It's not actually in her normal personality to snap like that.]]
* CuteBruiser: Once she goes into "Cute Mode", she's prone to {{Megaton Punch}}ing anything in the nearby area, even without her famous cleaver handy. Able to snap the rope that has her tied up with ease. Can wield the axe without any difficultly also. And probably brought home the statue of Col. Sanders[[note]]the KFC mascot[[/note]] that's bigger than she is without any assistance. When HilarityEnsues she doesn't hesitate to hit her friends, and she's thrown tables a few times when things get rough. She's apparently quite strong.
** Keiichi thinks that he wouldn't be able to beat her in a fight. The climax of ''Tsumihoroboshi-hen'' shows [[spoiler:he was ''right''.]]
* CutenessProximity: One of her [[RunningGag Running Gags]]. However, she doesn't have quite the same idea of what's "cute" as most people do.
* DaddysGirl: Remained very loyal to her father after her mother betrayed/cheated on him, and as shown in ''Tsumihoroboshi-hen'' she is willing to go to [[MurderIsTheBestSolution extreme lengths]] to protect him. If only he were worthy of such loyalty...
* DarkActionGirl: When she's under the Hinamizawa Syndrome's effects.
* DarkAndTroubledPast: She discovered that her mother cheated on her father. While her parents were finalizing their divorce, she [[spoiler: attacked her classmates while suffering from Hinamizawa Syndrome. She then attempted suicide and was treated with medication and therapy]]. She and her father then moved back to Hinamizawa to start a new life.
* ElmuhFuddSyndwome: This is how the English translation of the manga decided to translate her [[CatchPhrase signature]] "kaaii" (A slurred way to say "kawaii," the Japanese word for "cute"). In the translation, it became "adowable", while in the sound novel translations it's rendered as "sho kyute".
* EvilLaugh: Gives a very nasty one in Tsukiotoshi-hen after [[spoiler:she burnt down Satoko's house.]]
* {{Expy}}: According to WordOfGod, her name and appearance were based on Lenna from ''VideoGame/FinalFantasyV'' (specifically, Rena's appearance was based on Lenna's SNES sprites).
* FigureItOutYourself: Rena asks for Keiichi to do this regarding how he hurt Mion's feelings in Watanagashi-hen.
* {{Foil}}: To Keiichi and the twins. She is more calm and quieter compared to the loud Keiichi or Mion. But when it comes to bad situations, she is the most insane and scariest. Shion is jealous that Rena is way more intimidating and perceptive than her.
* GiantWaistRibbon: Part of her usual outfit.
* GirlWithPsychoWeapon: She's quite famous for wielding a cleaver.
* GlurgeAddict: Subverted; while she is obsessed with "cute" things, her idea of what's "cute" isn't the same as most people's (like a statue of Colonel Sanders, for example).
* HotBlooded: She defiantly shows this, sometimes to the degree of Keiichi, whenever she snaps out of her calmness.
* HyperAwareness: Seen best in ''Watanagashi-hen''. Most of the time [[ObfuscatingStupidity she hides it very well.]]
* IfItsYouItsOkay: Pulls that move on Keiichi during the zombie-tag game to "paralyse" him.
* ImageSong: "Egao Happy Peace"
* ImTakingHerHomeWithMe: TropeNamer. Not only does she often declare that she wants to take cute things and people home with her, but she'll frequently try to physically run off with them.
* InterruptedSuicide: [[spoiler:Motivated her to return to Hinamizawa.]]
* KillItWithFire: In Tsumihoroboshi-hen [[spoiler:she plans to burn down the school along with the hostages and herself should Oishi doesn't agree to investigate the Sonozaki.]] She also [[spoiler:burns down Satoko's house to kill Keichi and destroys the evidences after succumbing to the syndrome in Tsukiotoshi-hen.]]
* KickTheSonOfABitch: Her killing of [[spoiler: Rina and Teppei in the 6th novel and Teppei again in the [=PS2=] "Exorcism Chapter".]]
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=58UO_uRup-U "Lunch Time"]] (although you only hear it in the first novel).
* LightningBruiser: ''Very'' fast when in Cute Mode. Avoiding her punches is actually a reflex-based mini-game.
* MacGyvering: A rare non-heroic example. She makes [[spoiler:a school-blowing bomb with a little gasoline, a cook timer and a base-ball.]] And it works horribly well, as ''Yoigoshi-hen'' shows us.
* MeaningfulRename: She changed her name from "Reina" to "Rena" to reinvent herself when she returned to Hinamizawa. She felt that, by removing the "i", she was removing her bad memories. She also changed the writing of the name from kanji to katakana; using katakana in a name was quite unusual at the time.
* MoodSwinger: It's hinted in the games that she's actually bipolar.
* MsExposition: In ''Tsumihoroboshi-hen'', as she explains Miyo's scrapbook to Keiichi.
* MurderIsTheBestSolution: [[spoiler:She seems to believe that it will prevent Hinamizawa from being destroyed.]] Instead, [[spoiler:it sends her down spirals of madness.]]
* MightyGlacier: In Higurashi Daybreak Kai, she has a weapon called an "Iron Clad Nata". This cripples her mobility, giving her no ability to run on the ground and having a very small stamina bar, meaning she floats very slowly in the air in a very short period of time. She also barely moves when she walks, giving her the slowest walk speed in the entire game. However, all her attacks are very powerful and have enormous range.
* NiceGirl: Her usual, normal self which fits the name in general. A cheerful girl with a sweet and friendly nature who has a high sense of morality, usually trying to do the right thing.
* NightmareFetishist: She finds some very odd things to be "cute". One of the TIPS say that [[spoiler:this might be a psychological reaction to prevent other people from entering and ruining her household]].
* {{Nosebleed}}: Has frequent ones in the Visual Novel, triggered by the presence of cute things.
* ObfuscatingStupidity: Compare her behavior at the end of episode 4 of ''Rei'' with her behavior in episode 5.
** For that matter, see the end of Watanagashi-hen. She figures out the identity of the killer [[spoiler:(mostly)]] just based on a flyer and the state of Rika and Satoko's dinner.
* ParentsInDistress: Rena wants to protect her father from two scam artists who want to steal one million yen from him.
* ParentWithNewParamour: Rena's mother divorced her father and married another man, resulting in a permanent estrangement between them.
* RedOniBlueOni: The "silent blue flame" to Keiichi's "furious red flame".
* SailorFuku: Her chosen school outfit.
* SilkHidingSteel: The scary yangire under her usual seemingly light and girly demeanor.
* SmarterThanYouLook: She's often underestimated due to her cute mannerisms and vaguely ditzy/detached manner. However, she possesses one of the most analytical minds among the cast.
* SoleSurvivor: Rena is the only person living in Hinamizawa to survive the [[spoiler:Great Hinamizawa Gas Disaster]] in the anime's adaptation of [[spoiler:Tsumihoroboshi-hen]]. Originally, in the visual novel, she's supposed to die with everyone else. In a more limited scope, she's also the only one of the TrueCompanions to survive the events of [[spoiler:Watanagashi-hen and Meakashi-hen]].
* StepfordSmiler: She acts cheerful, but she has a lot of issues and insecurities and actively tries to keep them surpressed most of the time.
* SupremeChef: A great cook, Satoko and Keiichi will fight for her side dishes.
* SurvivalMantra: "Hauuu~ I'm taking her home with me!"
* ThereAreNoTherapists: Averted. She ''did'' see a therapist after the little... ''incident'' at her old school.
* ThirdPersonPerson: Usually when she's joking around.
* ThroughHisStomach: She tries this with Keiichi in the third episode of ''Kira''.
* TheUnsmile: There is her happy and cheerful [[ImTakingHerHomeWithMe "cute mode"]]. There is also her "Oyashiro-sama mode". Her smile in this mode is described as looking "as a sharp cut from a knife".
* TomboyAndGirlyGirl: Girly Girl to Mion's Tomboy.
* VerbalTic: She has a case of Palilalia which is the ocasional repeating the last words of her sentences, most notably "kana, kana?" ("I wonder, I wonder?"). Done to very sinister effect in ''Tsumihoroboshi-hen''. As an added bonus, "kana" is also one of the onomatopoeias for the cry of cicadas.
** Also "Haooo..." when bashful, depressed, or suffering CutenessOverload.
* WeaponOfChoice: A japanese gardening tool called a "nata". The in-game text called it an axe on the first chapter but promotional game art showed her using the more distinctively shaped weapon, and it stuck. Eventually the in-game dialogue started referring to it by name (Rena was nicknamed "nata-onna"), and the english translation started to call it a cleaver thanks to its rough silhouette (by extension, Rena herself was nicknamed "cleaver girl"),though that it has more in common with similar gardening tools such as billhooks and machetes.
* WellIntentionedExtremist: ''Tsumihoroboshi-hen''. [[spoiler:She genuinely believes that her actions in that arc are going to save Hinamizawa from the disaster. Ironically, it might actually have, at the cost of the lives of all her hostages.]] She also just wants the happy days in Hinamizawa to last, [[spoiler:it's just that she thinks that MurderIsTheBestSolution]].
** Although we later learned in Yoigoshi-hen that [[spoiler:it is NOT the solution at all as Takano still has the entire town gassed anyway.]]
* WiseBeyondHerYears: ''Tsumihoroboshi'' clearly shows it, especially the sound novel.
* WomanInWhite: Her play clothes are almost completely white except for her boots and a purple ribbon.
* WouldHurtAChild: In ''Tsumihoroboshi-hen'', she held her classmates hostage and threatened to bomb the elementary school with all of them inside.
* ZettaiRyouiki: In an odd way in the VisualNovel. [[http://imgur.com/oz59Q.jpg Is she wearing anything at all under there?]]

[[folder:Mion Sonozaki]]
!!"[[TheLeader Club Leader]]" Mion Sonozaki
!!!Voiced by: Creator/SatsukiYukino (JP), Creator/MeganHollingshead (EN)
The oldest classmate in Keiichi's class. As the elder, she is the class president and everyone looks up to her as the leader. Her social skills are on par with Keiichi, whom she highly respects as a friend and rival (though it is later shown that she has a crush on him). She acts boyish, but has a hidden girlish side. She is next in line to be the head of the Sonozaki household, one of the Three Families which holds tremendous influence in Hinamizawa. Her position as heir is marked by an oni tattoo on her back.

The second arc, Watanagashi-hen (Cotton-Drifting chapter), is focused on her.
* BadLiar: When impersonating her sister. Keichii doesn’t exactly buy it, but plays along anyway.
* BerserkButton: Shown in ''Matsuribayashi-hen'', [[spoiler: do not bring the resentment against the Houjous into the school. As the "den-mother" for the students, you'll regret it]]. This BerserkButton [[spoiler: is the only one in this series that doesn't result in bloodshed]].
* BlatantLies: In ''Watanagashi'', Keiichi first thinks her having a twin sister is this. He was wrong and right at the same time. [[spoiler:The few times they meet at the beginning it's ''really'' her pretending to be her twin. The last time though, it's the real Shion.]] [[BadLiar Her red face and stuttering when asked about Shion and Angel Mort really don't help.]]
* {{Bokukko}}: Refers to herself as "Oji san" or old man, and "Uncle Mion".
* BoobsOfSteel: Very busty and ''very'' competent in close combat. She hands [[spoiler:Okonogi]]’s ass to him beautifully in ''Matsuribayashi''.
* BookDumb: She may need to ask Keiichi for help studying, but that does not mean she's stupid.
* BreakTheCutie: When she is threatened to die. [[spoiler:And when Shion starts breaking her down]].
* CainAndAbel: The Abel versus Shion. [[spoiler: Though not as much as you are lead to believe, since Mion and Shion genuinely love each other. She even had three of her fingernails ripped out because she thought it wasn't fair that only Shion had to suffer.]]
* CallingTheOldManOut: [[spoiler: Calls Oryō out over her unfair treatment of the Hojo siblings after the [[{{MoralEventHorizon}} "distinguishment incident"]] offscreen (talked about in the Eye Opening chapter). The incident was the last straw as Mion was comtemplating KILLING HER in a NobleTopEnforcer style rebellion.]]
* CannotSpitItOut: Even [[spoiler:pretending to be Shion to show her feminine side to Keiichi]] doesn't really help.
* CheshireCatGrin: Often before she [[{{TheGadFly}} decides to mess with someone]].
* ClubPresident: The Class/Club President. The school is so tiny that she can get away with being both.
* ComatoseCanary: In the Playstation-only [[spoiler:Taraimawashi-hen]], the inspiration for Satoko's scene in Yakusamashi-hen.
** Also in the one-shot chapter ''Hinageshi-hen''.
* CreepyMonotone: At the end of Taraimawashi-hen, her lines are delivered in a monotone that is half-creepy and half-depressing in the context of being a [[spoiler:ComatoseCanary]].
* CurtainsMatchTheWindow: Green hair and green eyes.
* DirtyOldMan: A boyish girl who is openly perverted, often joking about sex towards Keiichi.
-->'''Keiichi:''' ''<internal narration>'' Thank goodness you were born a girl. If you were a boy, you'd probably be a perverted asshole...
* DualWielding: She uses the traditional "katana and wakizashi" combination in ''Yoigoshi-hen''.
* EmptyShell: See ComatoseCanary.
* {{Fingore}}: [[spoiler:Similar to Shion below, she pulled off three of her own fingernails (though unlike Shion, she did so off screen) because she felt it was unfair that only Shion got punishments despite them being identical twins.]]
* {{Foil}}: To [[PolarOppositeTwins Shion]]
* ForcedIntoEvil: She's forced by her family to take part in many morally corrupt deeds, but she's not happy about it.
* AFriendInNeed: The origins of [[spoiler: the club]].
* FriendToAllChildren: She is a friendly and protective club leader who is well liked by all the younger classmates.
* TheGadfly: Really loves cranking Keiichi's chain, in part because she's really bad at expressing how she really feels. Her punishment games also show this side of her personality.
* GagBoobs: The Sonozaki twins are the 'bustiest' of the gang.
* {{Gaslighting}}: Tragic and unintentional example in Tatagoroshi-hen, where [[spoiler:she is the accomplice to Teppei's murder trying to prevent a repeat of the events of 1982, but her attempts to help Keichii convince him that he’s going insane]].
* GenkiGirl: When she gets ''way' too excitable and hammy during games or punishment games.
* GoodBadGirl: Prevalent in the manga where she does such [[SarcasmMode wholesome]] things as grope Keiichi's rear in the Cotton Drifting chapters and raunchily stares at his crotch in the Curse Killing chapter. Gets blurry since its hard to tell how much of it is her being a pervert and how much of it is it being her normal [[TheGadfly gadfly]] self. Note that acting perverted is one of her favorite tactics for messing with people.
* GuileHeroine: Very much so, to almost MagnificentBastard levels. See TheStrategist.
* HairDecorations: Her yellow, ponytail-tying hair ribbon.
* ImageSong: "Futari no birthday" and "Ienai Kotoba".
* IWantMyBelovedToBeHappy: Had feelings for Satoshi, but sealed them for her twin's sake.
* LadyOfWar: Becomes this in spades in the alteverse sequel manga, Yoigoshi-hen. [[spoiler: This technically applies to her twin sister Shion as well, whose body she is possessing.]]
* TheLancer: Although technically the leader of the club, in terms of the plot, she takes this role with Keiichi.
* LargeHam: She can get '''very''' hammy during club games.
* TheLeader: She isn't TheHeroine, but she directs the groups' activities. As the oldest member, she usually coordinates the abilities of everyone to [[TheStrategist maximum and frightening effect]] in and out of battle. Thus showing [[BrilliantButLazy her brilliance despite being the most laid back of the group.]]
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=KmmU8HWWgvg "Spring Step"]] (shared with Shion).
* LuminescentBlush: Happens every time Keiichi says nice things to her. And it's adorable.
** Also, note hug in the Atonement arc.
* MsFanservice: Her sexy outfits during the punishment games.
* MyGreatestFailure: [[spoiler: The reason she refuses to talk about Satoshi is because she was unable to save him. To clarify, Satoshi specifically asked her for help dealing with his obviously abusive aunt, but Mion's grandmother ordered her not to. The only thing Mion did (could do?) was establish a 'safe zone' at their school where the Houjous were not ostracized or bullied. She blames herself for Satoshi's trauma, believing that if she had had the courage to rebel against her family, he would be alive. Which may or may not be true. It should be noted, however, that this was happening around the time when ''Shion'' tried to rebel against the Sonozakis and got three fingernails ripped out in a formalized torture ritual because of it.]]
* NiceGirl: Once you get past her playful competitive side, she's very friendly and one of the kindest members of the cast. [[spoiler:And unlike Rena, who is just as nice, she technically has no dark backstory and according to Rika she never succumbs to Hinamizawa Syndrome.]]
** This is because she's the only protagonist to have gone through full CharacterDevelopment pre-series (Keiichi also developed, but not fully). [[spoiler: After Satoshi's...disappearance, which she believes she could have prevented, she resolves to make sure nothing like that ever happens again. Hence, she is deeply loyal to her friends and very protective of those she loves.]]
* ObliviousMockery: In ''Tatarigoroshi'', she eagerly and repeatedly mocks Keiichi's lunchbox, pointing out what a terrible cook he is, with Satoko nodding and snarking in agreement. Except Satoko is actually the one who made the food in said lunchbox.
* {{Ojou}}: Heir to a prestigous family, though she doesn't quite act the part, except when she is in a formal meeting [[spoiler:or has to witness her sister's punishment]].
* OneOfTheBoys: Mion has trouble not just getting her feelings across to Keiichi but also getting him to acknowledge her actual gender.
* OnlySaneWoman: Compared to the others, she doesn't have as much of a DarkAndTroubledPast, and is one of the more psychologically well-adjusted characters in the cast. According to Rika, she's [[spoiler:the only member of the known group to never succumb to Hinamizawa Syndrome's paranoia. Even Rika herself apparently fell victim to it, though since she's so weak she never caused much damage.]]
* PlausibleDeniability: As per her grandmother's indirect phrasing during family planning meetings. [[spoiler: This is a clue that the MotiveRant at the end of Watanagashi-hen wasn't from her.]]
* PolarOppositeTwins: Mion is a tomboy, openly perverted but secretly shy and calm when not playing games. Shion is a girly girl, TheTease instead of perverted and tends towards being selfish and actually hotblooded. Mion herself states that she's the warm friendly one while Shion is cold.
** It's actually {{subverted}} to some extent. At first, they seem very different, (even if one takes into account all the TwinSwitch confusion) but then Meakashi reveals they're both [[TheGadfly gadflies]], both friendly, both somewhat cheerful, both socially intelligent, both have weak spots the size of Mount Fuji when it comes to romance, both hate their grandmother, both adept at manipulating people. The main difference is how they approach these similarities; in the latter example, Shion likes to manipulate on a personal level, swaying individual perceptions; Mion likes to manipulate groups, with speeches and military tactics and ginormous guns.
* RapunzelHair: Long hair when not wearing a ponytail.
* RedOniBlueOni: Red Oni to Shion's Blue. [[spoiler:But her ''true'' personality is Blue; she acts Red because it is expected from the "older twin" role she is forced to play]]. The archetype is referenced by her blue oni tattoo.
* ShipperOnDeck: She plays this role for Keiichi and Rena during the festival in ''Onikakushi'' (especially in the sound novel). [[FridgeLogic Which is quite baffling]] when we learn her feelings for Keiichi in the following arc.
* {{Shorttank}}: Towards Keiichi when angrily snapping at him.
* SignatureLaugh: An awesome one can be heard a few times in the anime, [[http://www.youtube.com/watch?v=9juWiTRRtjw notably at the end of the Zombie Tag.]] GAHAHAHAHA!
* SingleWomanSeeksGoodMan: Revealed to be the reason she likes Keiichi so much during the Eye Opening chapter.
* SoleSurvivor: [[spoiler:She is the only survivor of Hinamizawa in Taraimawarashi-hen as she was imprisoned by Shion in the torture chamber which allowed her to evade being killed by Yamainu]]. This however [[spoiler:left her in a minimally conscious state for the rest of her life]]. The story contradicts itself about the cause. One of the TIPS speculates that it was emotional trauma about what she witnessed, but in the ending of the arc, the narration states that it was from a physical injury to the head (presumably from when [[spoiler:Shion locked her up]]).
** She also appears to be one in Yoigoshi-hen, [[SubvertedTrope up until]] Arakawa mentions that he looked at the records from [[spoiler:after the school blew up]], and [[spoiler:Mion is listed as among the dead there]]. [[spoiler:It's actually her twin sister Shion who has this role]].
* SpiritedCompetitor: Moreso than the rest of the club unless Keiichi or Rena get fired up.
* TheStrategist: "If she had joined [[UsefulNotes/NapoleonBonaparte Napoleon]], Siberia would be French territory by now. If she had joined [[UsefulNotes/AdolfHitler Hitler]], the Third Reich would be all over Europe."
* SuspiciouslySpecificDenial. S-stupid Kei-chan! I'm just accepting this doll be-because you insist, n-not because I like it! S-so don't get the wrong idea!
* TeamMom: Being the oldest of the group and the leader as well so this naturally fall into her position.
* TheTease: In the manga especially, she has quite a few moments of this in the beginnings of different arcs. Is actually one of her favorite tactics for use in screwing with Keiichi, see TheGadfly above.
* ThemeTwinNaming: The "on" in Mion and Shion is the same kanji, 音 (meaning "sound").
* ThirdPersonPerson: Sort of. She uses ''ojisan'' ("old man") as a first-person pronoun. She does use ''[[UsefulNotes/JapanesePronouns watashi]]'' sometimes though.
* TomboyAndGirlyGirl: She's a tomboy, while her twin sister Shion is more feminine. [[spoiler:At least it appears as such. As noted under RedOniBlueOni, the two act this way because it is expected from them. Deep down, Mion is quite girly, while Shion is, [[BreakTheCutie well]], [[{{Yandere}} you]] [[AxCrazy probably]] [[KillEmAll know.]]]]
* TomboyishPonytail: A [[RapunzelHair very long]] one, which may also hint at her [[LongHairIsFeminine girlish side]].
* TomboyWithAGirlyStreak: She's a very boisterous GenkiGirl who seems like a tomboy. Later, we learn that Mion is actually really girly. If one looks closely, her ''desires'' are feminine (she wants to spend time with her friends, she's attracted to Keiichi, etc.) but her ''methods'' are very masculine. (She takes a leadership role among her friends, often deciding when and why they meet; she gropes Keiichi, jokes about wanting to have sex with him - you get the idea.)
* {{Tsundere}}: A unique type B. She neither acts terribly tsun nor dere, but has the classic signs of denying her attraction or her desire for things. Note that since her "nice side" is the dominant personality, she has type B leanings.
* SiblingYinYang: Her usual rough demeanor is black but actually has a softer side (white). While Shion, on the other hand, seems more proper and considerate (white), but is really cold and insane (black).
* TwinSwitch: Frequently with Shion. It's even already hard to tell them apart since they look the same and can impersonate each other. [[spoiler:As children, they switched ''permanently'']].
* UnreliableExpositor: The Sonozaki family is often implicated in the goings on in the village, meaning that of all the cast she has some of the best reasons to lie. [[spoiler:Subverted. More than just about anyone else, you can trust what Mion has to say. However, tricks can be played on the reader such as 'Mion' confessing to all the murderers and talking about the history of the village and really playing up the angst. However, not only is this not Mion, Shion was actually bullshitting throughout the entire thing, meaning that at least half of what she said was a lie.]]
* UnusuallyUninterestingSight: No one ever comments on the gun she carries around. It's an airsoft gun, but you'd still think it would draw some attention...
* WaifFu: [[spoiler:Matsuribayashi reveals that she's excellent in hand to hand combat.]]
* WeaponOfChoice: [[spoiler:[[IKnowKarate None]]]]. However, in ''Higurashi Daybreak'', she wields her airsoft gun, and in the manga-only chapter Yoigoroshi-hen, she is convinced that KatanasAreJustBetter.
* YakuzaPrincess: To the point of being heir apparent to the whole gang.
* {{Yandere}}: One of the TIPS reveal that she was driven to kill because of jealousy that Keiichi gave the other girls more attention. Mion wanted to 'eliminate the competition' so she can have Keiichi all to herself. Though this is only an occasion, making Mion mostly sane and way less of a yandere than her twin.
* YouGottaHaveBlueHair: She has green hair.

[[folder:Shion Sonozaki]]
!!Shion Sonozaki
!!!Voiced by: Creator/SatsukiYukino (JP), Creator/MeganHollingshead (EN)
Mion's identical twin sister, who currently resides in Okinomiya. Unlike her twin, she is girly and somewhat cold. In spite of their different personalities, she and Mion often switch places, and it can be difficult to distinguish between them. She was sent by the Sonozaki family to a private boarding school, but escaped and returned to live near her hometown, where she lives with Kasai. She was in love with Satoshi, and blames the Three Families of Hinamizawa for his disappearance. She works as a waitress at the ''Angel Mort'' restaurant and is the manager's assistant for the Hinamizawa Fighters little league team.

The fifth arc, Meakashi-hen (Eye Opening chapter), is focused on her. Infamous for its content. Administrivia/YouHaveBeenWarned.
* AdaptedOut: She's the only member of the party who doesn't appear in the live-action movies. Granted, she doesn't appear ''Onikakushi'' and only has a minor role in ''Tsumihoroboshi'' (the two arcs the movies adapt).
* AlliterativeName: '''S'''hion '''S'''onozaki.
* TheAtoner: [[spoiler:After realizing what she did in the Eye Opening Arc, she becomes especially aggressive in protecting Satoko in later arcs.]]
* AssholeVictim: [[spoiler: After everything she does over the course of Meakashi-hen, by the time she dies at the end she's thoroughly unsympathetic.]]
* AxCrazy: '''Incredibly so'''. She's one of the most dangerously psychotic and violently unstable characters in the whole series. Viciously torturing and murdering several innocent people in the course of just a few days, and all for a guy she just met.
* [[spoiler:TheBadGuyWins: Though she ends up regretting her actions, she still succeeded in taking revenge on all of her intended targets, and she dies without having to face any justice.]]
* BecauseYouWereNiceToMe: She falls head-over-heels for Satoshi after he merely pats her head. She wonders herself how that could happen so easily.
* BerserkButton: During the arcs where she is a Yandere, even ''looking'' at Satoshi in a way she doesn't like is a good way to set her off. Special mention goes to [[spoiler:her bullying of Satoko for calling him ''nii-nii'']].
* BigLittleSister: Seeing how she plays Mion like a harp and acts somehow superior to her, you really wouldn't think she's the younger twin. [[spoiler:[[{{Foreshadowing}} And that's because she is the older one.]]]]
* BoobsOfSteel: Similarly to Mion.
* BreakTheCutie: [[spoiler: Warnings about tormenting cute things apply. She doesn't simply break or snap, she ''explodes''.]]
* BringMyBrownPants: In the anime, she wets herself [[spoiler:after killing Satoko and [[MyGodWhatHaveIDone suddenly remembering Satoshi's last wish]]]]. Some fans have theorized that what comes out between her legs is not urine. Not that she cares anymore at that point.
* CainAndAbel: The Cain versus Mion. [[spoiler:Though not as much as you are led to believe, since Mion and Shion genuinely love each other.]]
* TheCameo: [[http://mangafox.me/manga/umineko_no_naku_koro_ni_episode_3_banquet_of_the_golden_witch/v05/c021/6.html She appears]] in a short-story of ''VisualNovel/{{Umineko|WhenTheyCry}}'', "Cornelia the New Priest" which doesn't make sense as that story clearly takes place in a Western town (or a different world?), but it's probably more of a joke anyway.
* TheCharmer: When Shion wants to be, she is very charismatic. This is especially clear in the Watanagashi chapter, where newcomer Keiichi has none of the locals' fear of her family, and she basically waltzes in and [[{{TheGadFly}} starts fucking with him.]]
* CheshireCatGrin: Much like her sister. [[spoiler:She takes upon a [[{{SlasherSmile}} different]] [[{{PsychoticSmirk}} smile]] when she turns into a {{Troll}}.]]
* ColdBloodedTorture: Her MO. [[HeWhoFightsMonsters Ironically,]] she was the victim of it herself.
* CoolBigSis: To Satoko, as a promise she made to Satoshi. [[spoiler: And horribly screwed with in arcs where she goes insane.]]
* CurtainsMatchTheWindow: Like Mion, her hair and eyes are both green.
* DangerouslyShortSkirt: In the anime only, curiously. In other versions, she wears a long skirt.
* DatingWhatDaddyHates: Her family is not happy about her being in love with Satoshi. [[spoiler:Subverted: Her grandmother long sinced stopped detesting the Houjou family but has to keep up appearances. It also turns out that the main reason the Sonozaki family was against the relationship was that Satoshi is a murderer, not that he is a Houjo.]]
* DesecratingTheDead: In Meakashi-hen, after she figures out that Oryou is dead, [[spoiler:frustrated that she didn't get to interrogate and (perhaps) torture her first, she lashes out at Oryou's corpse with a barbed whip over and over again]].
* DesperatelyCravesAffection: A lot of Shion's actions and emotional responses make more sense when you remember how lonely she must feel. She's been estranged from her family for years at a time (and they were abusive to begin with), separated from her sister, and the closest thing she has to a guardian is a bodyguard who admits he would side with Shion's family over her. Fortunately, this gets better once she joins the main characters and has actual friends to support her.
* DisneyVillainDeath: [[spoiler: In the Cotton Drifting and Eye Opening chapters.]]
* DoesNotLikeSpam: She hates canned foods because Kasai traumatized her into thinking that human meat gets packed inside.
* DrivenToSuicide: [[spoiler:In ''Watanagashi-hen'' and ''Meakashi-hen'', excluding the anime.]]
* EasilyForgiven: [[spoiler:While still believing her to be Mion, Keichi and Rena listen to Shion admit that she murdered Rika and Satoko. They literally forgive her immediately for this and still consider her to be their beloved friend. It's...weird.]]
* FanserviceWithASmile: Her job at ''Angel Mort''.
* {{Fingore}}: [[spoiler:Forced to pull out three nails in order to protect people she had endangered.]]
* {{Foil}}: To [[PolarOppositeTwins Mion]].
* {{Foreshadowing}}: From Frederica Bernkastel's poem in ''Meakashi-hen'': "How many years will pass before she wonders if she really dropped them?"
* FragileSpeedster: In ''Higurashi Daybreak''. She has A LOT of mobility options and great damage in the melee department. She also has the fastest walk and run speed and second best air dash speed, behind non-scythe Rika. She also travels quite the distance when attacking someone with a regular attack, dashing forward a few feet forward before actually attacking them, depending on the distance, giving her deceptively good range in melee. However, she is almost the first to be knocked out in a game, has less than an average health and has one of the lowest defenses in the game, along with Rika.
* TheGadfly: Her normal personality, with her favorite targets being Mion, Keiichi, and sometimes Kasai.
* GagBoobs: See Mion's entry.
* {{Gainaxing}}: In some of the most disturbing scenes.
* GirlyGirlWithATomboyStreak: She inverts [[TomboyWithAGirlyStreak her twin]] because she is very girly, but is just as spunky and is as much of TheTease as her twin. She has some HotBlooded traits as well.
* GoOutWithASmile: [[spoiler:Despite the shame and remorse she feels in her final moments in ''Meakashi-hen'', she dies pretty happy. The visual novel and manga versions suggests she finds her own Heaven after coming to terms with herself.]]
* HairDecorations: Her yellow ribbon.
* {{Hammerspace}}: Appears to be where she kept her taser as none of her outfits at time seem to feature any pocket.
* IgnoredEpiphany: Her reaction to realizing she just [[spoiler:crucified Satoko]] was, number one: [[spoiler: wetting herself]]. Number two: Saying "Oh, what the hell". In the VN, it's expanded upon: [[spoiler: She realizes that she forgot her promise to Satoshi, it's just that she felt it was already too late to atone, and she had no choice but to continue what she was doing.]]
* ImageSong: "Futari no Birthday" and "Ienai Kotoba", along with Mion.
* ItAmusedMe: The main reason for her love of screwing with people; she's been stuck out in Okinomiya with no-one to talk to and nothing fun to do. By the time of her introduction, she's bored as hell.
* IWillWaitForYou: Ever since Satoshi disappeared, Shion has been clinging to the hope that he will return someday and she will be waiting for him until then. Although two arcs involve what happens if she gets tired of waiting and decides to seek revenge instead. It's not pretty.
* KickTheSonOfABitch: Common reaction to her killing [[spoiler: Oryou in the 2nd/5th novels]] and [[spoiler:Teppei in the [=PS2=] exclusive "Exorcism Chapter".]]
* KnightTemplarBigSister: For Satoko after the Meakashi arc concludes and she remembers in future arcs that she was asked to protect her. She even would have killed Satoko's uncle to free her if Keiichi haven't stopped her.
* LaughingMad: In Meakashi and Watanagashi.
* LongHairIsFeminine: To contrast with her [[TomboyishPonytail twin]], she is a girly girl with her hair down.
* LoveMakesYouCrazy: ''Boy does it ever.'' Could also count as LoveMakesYouEvil.
* LovingAShadow: Her attraction to Keiichi mostly comes from how he reminds her of Satoshi.
* ManipulativeBastard: Frequently, particularly in ''Meakashi''.
* MatchmakerCrush: Has some feelings for Keiichi, but represses them to get her twin with Keiichi. Also, in ''Watanagashi'', even if she takes a rather unsympathetic delight at making Mion jealous, she does make Keiichi realize that Mion loves him. Then things go downhill from there.
* MisplacedRetribution: She goes on a RoaringRampageOfRevenge against the Sonozaki family in Watanagashi and Meakashi-hen because she's sure they are responsible for Satoshi's disappearance. [[spoiler:Turns out they really had nothing to do with it.]]
* MsFanservice: The fact that she works at Angel Mort.
* MyGodWhatHaveIDone: [[spoiler:After torturing Satoko to death she remembers that Satoshi asked her to take care of his little sister and that while she gave up on Satoshi coming back and went for revenge, Satoko never lost faith. Has a straight example in the Massacre chapter after recalling what she did.]]
* MySiblingWillLiveThroughMe: In Yoigoshi-hen [[spoiler:the world that Mion died in Rena's explosion, her spirit is with Shion.]]
* OffToBoardingSchool: Her family sent her to one that she managed to escape from before the beginning of the plot.
* {{Ojou}}: Subverted. As the younger twin, she is denied of family's privileges.
* PolarOppositeTwins: Has this dynamic with Mion. See Mion's entry for details.
* ProperLady: Seems so with her usual self, until she isn't sane.
* PsychoticSmirk: [[spoiler:When she's a {{Troll}} instead of her usual self.]]
* RapunzelHair: She likes to keep it naturally long unless she's impersonating her sister.
* TheRashomon: ''Watanagashi-hen'' was told from Keiichi's point of view, and Shion retells it in ''Meakashi-hen''. [[spoiler:Sorta. They actually ''are'' different ways of playing out the same sequence, but a few details differ such as who knocked over the bike and had someone come to their rescue, or the fact that Rika [[BetterToDieThanBeKilled "exits the stage" herself]] in ''Meakashi''.]]
* RedOniBlueOni: Blue Oni to Mion's Red. [[spoiler: But her ''true'' personality is Red; she acts Blue because it is expected from the "younger twin" role she is forced to play]].
* TheResenter: Normally suppressed, but she has some resentment for Mion because she can still see the boy she likes.
* RoaringRampageOfRevenge: Her motive in Watanagashi and Meakashi-hen.
* SerialKiller: [[spoiler:Unlike other arcs, her murders occur over the course of days. Visionary type combined with revenge sub-type due to Hinimizawa syndrome.]]
* SheWhoFightsMonsters: [[spoiler:In Watanagashi and Meakashi-hen.]]
* ShipperOnDeck: For Mion and Keiichi; she may or may not have a MatchmakerCrush on him, but Sane!Shion doesn't let that stop her. In Matsuribayashi, [[spoiler:when she and Kasai are about to make what everyone thinks will be a HeroicSacrifice, Keiichi asks Shion what her last words are.]] Her response, paraphrased, is essentially: [[CrowningMomentOfHeartwarming "Tell Mion I love her and I hope we're twins in the next life]]...also, you know my sister wants to bang you, right?"
--> '''Keiichi:''' What?
* SiblingYinYang: See Mion's entry.
* SilkHidingSteel: Despite her refined and girly persona, she is either a violent yandere or a badass tease like her sister.
* SixthRanger
* SpannerInTheWorks: Her actions in Watanagashi and Meakashi are what saves the village in those two arcs. [[spoiler:More than two days pass between Rika's death and the finding of her body, but no villager has gone insane, destroying the basis of the Emergency Manual 34, and thus preventing the Hinamizawa disaster. Too bad Shion tortured and killed half of the main cast in the process.]]
* StartOfDarkness: Subverted with the [[spoiler: "distinguishment scene"]]. It is so in arcs where she snaps but not in arcs where she doesn't.
* TheTease: Regularly and unsubtly hits on Keiichi, ''especially'' if Mion is with them. MarshmallowHell optional.
* ThemeTwinNaming: The "on" in Mion and Shion is the same kanji, 音 (meaning "sound").
* TomboyAndGirlyGirl: The Girly Girl to Mion's Tomboy. [[spoiler:At least it appears as such. See Mion's entry for details.]]
* {{Troll}}: During Watanagashi and Meakashi, for which she is the protagonist of, she acquires a certain fondness for breaking people and causing severe pain, both physical and emotional. More in the PlayedForLaughs vein, she also basically steers Keiichi over to the toy shop where Mion works in order to get him to buy the doll that he failed to give to Mion (an unintended insult that she had told Shion about and was still smarting over) for her. She does similar activities as TheTease a few different times, mostly when Mion's around.
* TwinSwitch: Frequently with Mion. [[spoiler:As children, they switched ''permanently'']].
* TheUnfavorite: As the younger twin, she is denied any family privilege. Especially painful because [[spoiler:she is really the older twin, and thus should be the Sonozaki heir]]. However, it seems that for the most part she doesn't entirely mind because it's not very fun having the responsibilities of the Sonozaki heir.
* UnreliableExpositor: Like a lot of the cast are at varying points. However, this is specifically referring to [[spoiler:almost the entirety of what she says at the end of ''Watanagashi'' being bullshit.]]
* UptownGirl: For Satoshi.
* VillainProtagonist: [[spoiler:In Meakashi-hen, she takes center stage by going absolutely insane in the pursuit of revenge.]]
* ViolentlyProtectiveGirlfriend: For Satoshi. '''GOOD''' '''''GOD'''''.
* VoiceChangeling: She can perfectly imitate Mion's voice.
* WalkingSpoiler: Its difficult to talk about Shion without spoilers for Watanagashi and Meakashi-hen.
* WeaponOfChoice: [[spoiler:A taser, as well as the contents of the Sonozaki family's torture cellar. She also knows how to handle an ''assault rifle''.]]
* WouldHurtAChild: She bullied Satoko and later [[spoiler: tortured and killed her.]]
* WoundedGazelleGambit: She has frighteningly good acting skills and can summon DistressedDamsel tears at will. She meets Satoshi thanks to that.
* YakuzaPrincess: As a daughter of the Sonozaki family.
* {{Yandere}}: During the arcs where she snaps, she goes on a RoaringRampageOfRevenge against those she blames for Satoshi's disappearance.
* YouGottaHaveBlueHair: Like Mion, she has green hair.
* YoungerThanSheLooks: Maybe it's her civil outfit, her behaviour and personality or her RapunzelHair, but for some reason she looks older than Mion. Add to that her apparent military training and experience with guns, and it's really easy to forget that she is 16.
* {{Yubitsume}}: What she had to do to gain forgiveness from her grandmother for running away from her boarding school.

[[folder:Satoko Houjou]]
!!"[[TrapMaster Trapmaster]]" Satoko Houjou
!!!Voiced by: Creator/MikaKanai (JP), Minx Lee (EN)
A younger classmate in Keiichi's school. In spite of her young age, she seems to have an impressive arm strength and is quite clever in setting up traps, which she likes to practice on Keiichi. Although her personality is quite energetic and mischievous during the events of the games, Satoko's past was full of trauma; her family were outcasts for supporting the dam project that would have destroyed the village, her parents died in an accident, she was abused by her foster parents (her aunt and uncle), and her beloved brother Satoshi disappeared. She greatly misses Satoshi, and feels that by being strong, he will return. She cannot tell the difference between cauliflower and broccoli because she is color blind.

The third arc, Tatarigoroshi-hen (Curse-killing chapter), is focused on her.

* AllOfTheOtherReindeer: Because her parents supported the dam construction, Satoko and the rest of her family are seen as outcasts by the rest of the village.
* BadassAdorable: See CuteBruiser.
* BigBrotherWorship: She adores her Nii-nii more than anyone. His disappearance really crushed her to a degree that you only begin to see in Tatarigoroshi-hen.
* BrattyHalfPint: ''Especially'' in the first ''Higurashi: Rei'' episode.
* BreakTheCutie: See the entire list of other tropes regarding her. More than anyone else, Satoko's history has been a list of things going wrong in her life. Tatarigoroshi-hen is when she finally breaks.
* BreakTheHaughty: Rei Episode 3.
* ButtMonkey: Besides her tragic past, it seems that, no matter who dies over the course of the series, one thing that's almost guaranteed is that Satoko's going to get beaten up at some point (most likely with a chair).
* CheerfulChild: Usually.
* ColorBlindConfusion: Both her and her brother are colorblind, which means they can't tell broccoli and cauliflower apart.
* ComatoseCanary: In ''Yakusamashi-hen''.
* CovertPervert:
* CrazyPrepared: Sometimes you wonder how and when she sets up some of the traps that she does and how she times them so well.
* CuteBruiser: She's strong enough to shove Keiichi across the room [[spoiler:or off a bridge, and she also shoved her mother and stepfather off a cliff. Considering that on all of these occasions she was crazed due to the effects of Hinamizawa syndrome, it isn't all that surprising]].
* CuteLittleFangs: Every so often during club activities, she shows these.
* DeceasedParentsAreTheBest: A revolving door of replacement daddies was hard enough to adjust to before she was left in custody of her aunt and then uncle. Confirmed in both Saikoroshi-hen and Miotsukushi-hen that [[spoiler:Mr.Houjou isn't a bad step father and if they're still alive she would have accepted him.]]
* DoesNotLikeSpam: She hates kabocha squash and complains about it very noisily in a few different arcs.
* DropTheWashtub: A preferred prank. She can summon them ''anywhere''.
* EntendreFailure: Presumably because she's one of the {{Token Mini Moe}}s, she is particularly prone to this. The one to lampshade this is usually Rika, the other one. Notably, she always gets it. Occasionally, it seems like she ''chooses'' not to understand the entendre. [[spoiler:Makes sense as Rika is a 100+ year old being pretending to be a child.]]
* FanDisservice: Her appearing fully naked (and ''not'' in BarbieDollAnatomy) in the bridge scene of the ''Tatarigoroshi'' sound novel only makes it more disturbing.
* TheGadfly: Very mischievous, especially towards Keiichi.
* GenkiGirl: Her facade is along these lines, until she [[BreakTheCutie breaks]].
* HairDecorations: She nearly always wears a black hairband.
* ImageSong: "Sukisuki Nii Nii".
* InsistentTerminology: They are not "pranks", they are "traps"!
* {{Keigo}}: She speaks in an extremely formal way, using the first-person pronoun "watakushi", forms like "de gozaimasu" and the honorific -san with even her close friends, as well as the request formula "-kudasaimase". There is no clear explanation for why someone as young as her would talk like this, but according to Rika that's because she forced herself to be hyper-polite so as not to be a target of gossip when the Hōjō were ostracized. It didn't really help.
* {{Leitmotif}}: [[http://www.youtube.com/watch?v=YxhEa_e9aZQ "Small Town".]]
* LivingEmotionalCrutch: We can assume that if not for her, Rika would have given up long ago.
* MoralityPet: To different character in different arcs, most notably Irie.
* MyGodWhatHaveIDone: You might miss it and you won't understand it at the time, but it happens at the end of ''Minagoroshi'' chapter [[spoiler:when she realizes that her parents weren't trying to kill her and she didn't need to push them off the cliff.]]
* NoblewomansLaugh: "Oh ho ho ho!"
* ParentalAbandonment: Boy, does poor Satoko get it bad. Her mother, father, aunt, and brother all died or disappeared, and her uncle skipped town.
** That last one ''really'' isn't a bad thing.
* ParentWithNewParamour: Satoko suffered from this in her backstory. Her mother and father divorced when she was young, and Satoko's mother remarried multiple times. She suffered abuse from some of them, but got along so poorly with the last one that she called the child abuse hotline falsely. [[spoiler:Ultimately, she deluded herself into believing her new stepfather and her mother were trying to kill her and shoved them off a cliff herself]]. The false call to the child welfare office unfortunately leads them to delay acting on reported abuse when Teppei returns in Tatarigoroshi-hen.
* SelfMadeOrphan: [[spoiler:An accidental, tragic example; her Hinamizawa Syndrome made her delude herself into thinking that her mother and stepfather were trying to kill her, and she shoved them both off a cliff in what she thought was self-defense.]]
* TheSmartGirl: The "TrapMaster" of the group. She can [[{{MacGyvering}} make weapons and traps out of anything]]. Her expertise even allows her to understand and figure out the things others make, such as [[spoiler:[[{{ChekhovsSkill}} quickly concluding that the bomb Rena created was hidden in the rain gutter on the roof.]]]]
* TechnicolorEyes: Pink and in some versions, Red.
* TricksterArchetype: See TheGadfly and TrapMaster.
* TokenMiniMoe: Along with Rika, she certainly seems to be younger than the other cast members.
* TrapMaster: It's her club title. [[spoiler: She can make traps that can catch ''trained soldiers'' off guard!]]
* TraumaCongaLine: [[spoiler:First, her parents die due to a tragic accident. Then, she and her brother are forced to move in with her abusive aunt and uncle. Then, her aunt is killed by her brother, her brother disappears a few days later, and her uncle abandons her.]]
* VagueAge: Like Rika, she's somewhere from 9-13, but specifics are never given.
* VitriolicBestBuds: She and Keiichi - except in Tatarigoroshi-hen, where Keiichi tries to act more like Satoshi - constantly snipe at each other, and it's very clear that their friendship is built on this dynamic.
* WeaponOfChoice: It's given more importance in the games, but she is quite good at making [[RubeGoldbergDevice traps]].
* YaoiFangirl: She seems a little bit TOO happy at the sight of [[spoiler: her brother about to feed Keichii will a spoon held in his mouth]] in the first episode of Kira.
** Then again, [[spoiler:[[AllJustADream Keiichi was dreaming that entire sequence]] so it might not be true.]]

[[folder:Rika Furude]]
!!"[[{{Tanuki}} Tan]][[DeliberatelyCuteChild uki]]" Rika Furude
!!!Voiced by: Creator/YukariTamura (JP), Creator/RebeccaForstadt (EN)
A younger classmate in Keiichi's school, who is in the same grade level as Satoko. Naturally, she is great friends with her, as they live together in the same house. She is the {{Miko}} of the Shrine of Oyashiro-sama, and some of the villagers revere her as a prophet. She has been the head of the Furude family since her parents died, but rarely attends town meetings due to her young age.

She is the only one who can see Hanyu, whom everyone else thinks is an ImaginaryFriend.

The seventh arc, Minagoroshi-hen (Massacre chapter), is focused on her.
* ACupAngst: Rika at one point laments her small breast size (due to not being done with puberty yet), and a DVD extra has her do a SkinshipGrope of Mion. There is also a manga omake where she is jealous of Hanyu's breasts (Hanyu is adult when in her ghost form in the manga). [[spoiler:The reason she's so hung up about this is because [[NotGrowingUpSucks she can never physically grow older]] thanks to the GroundhogDayLoop.]]
* AdaptationDyeJob: Rika's hair is blue in the original sound novels, but the anime gives it a more purple tint.
* AffectionateGestureToTheHead: Often does this to people. While most assume that it's her way of comforting them, she's actually mocking them.
* AndIMustScream: [[spoiler:She has been stuck in a GroundhogDayLoop for somewhere between a century and a millennium. In most iterations, one of her friends will [[HatePlague go insane and kill a bunch of people]]. In every iteration, she is murdered, usually [[CruelAndUnusualDeath disemboweled while she's still alive]], and most or all of her friends die within a few days. Then she's resurrected in the past, and goes through it all over again, and she's the only one who remembers what's happening, but enough important details keep changing that she can't manage to stop it.]]
* AnimalMotifs: Between her punishments (often involving having to wear cat ears), her VerbalTic ("Mii~", which is meant to be a kitten's mewing), and her general behaviour, characters in the sound novel often compare her to a kitten. And there is a mini-game where she's dressed as a CatGirl. The theme is perpetuated by [[spoiler:her other self]] Bernkastel in ''VisualNovel/UminekoWhenTheyCry'', who has a cat's tail and can turn into a cat. Oddly enough, her club title compares her to a {{Tanuki}} instead.
* BadassAdorable: Near the end of arc 6: [[spoiler:Fighting against a psychotic girl who is 4-5 years older than you physically, is stronger than you, and is wielding a hatchet, with a mop, and surviving to tell the story. That's no easy feat. And who could forget the line "I'll play with you. Come on, hatchet girl!"... *Nipaa~*]]
* BarrierMaiden: [[spoiler:Her role as Infection Queen. However, this is subverted when the FridgeLogic of the ending of Meakashi-hen settles in.]]
* BlushSticker: As a little child.
* {{Bokukko}}: Uses "boku" as a first-person pronoun, probably a habit acquired from Hanyu.
* BrokenBird: Underneath her cheerful and innocent exterior, Rika is actually a cynical and desperate girl who has almost entirely given up on her future after [[spoiler:being repeatedly killed in gruesome ways]].
* CassandraTruth: Rika has long since given up trying to convince people that she knows the future.
* CheerfulChild: [[spoiler:Or so it seems.]]
* ChekhovsGunman: During the first half of the story, she gets the least amount of focus out of all the Games Club members. [[spoiler:In ''Kai'' we learn a great deal more about her relevance to the plot, and she essentially replaces Keiichi as the main protagonist.]]
* TheChessmaster: Very intelligent and precise when fighting.
* ContraltoOfDanger: Whenever she drops the innocent child act, she also drops her high-pitched voice and sounds deeper while showing her more cynical true self.
* CovertPervert
* CreepyChild: She occasionally acts in a knowing, creepy manner completely unfitting her age. [[spoiler:[[ReallySevenHundredYearsOld There's a reason for this]].]]
* CruelAndUnusualDeath: [[spoiler: She is a frequent victim of this, usually involving disembowelment.]]
* CurtainsMatchTheWindow: Only in the anime, which gives her purplish-blue hair and eyes. In all other media, her hair is blue and her eyes are purple.
* DeadpanSnarker: In the silly episode previews.
** Also a majority of her dialogue consists of this when she isn't being innocent or serious.
* DeliberatelyCuteChild: Even before the reveal that [[spoiler:she's mentally much older than she acts]], you still get the sense that some of her cutesy behaviour is deliberate.
* DeterminedDefeatist: [[spoiler:She has been trying for a long, long time, but she's been killed so many times that she's become a cynical fatalist. She keeps trying though, and eventually gets it right.]]
* DrivenToSuicide:
** [[spoiler:She is captured and tortured to death by Shion]] in ''Watanagashi''. In ''Meakashi'', when she ends up in the same situation again, [[spoiler:[[BetterToDieThanBeKilled she prefers to skip the torture part and kills herself with a kitchen knife]].]]
** [[spoiler: She also almost kills herself in ''Minagoroshi-hen'' when she finds out that Satoko's uncle has returned and neither Takano or Tomitake can help her. She stops once she realizes that by doing this she would just leave this world's Satoko alone.]]
* DrowningMySorrows: [[spoiler:She drinks wine when she's depressed, despite being underage. She knows she's fated to die anyway, so what harm could it do.]]
* EmotionlessGirl: She is not, but is afraid of becoming one [[spoiler:because of the repetition of an increasingly short period of her life.]] This is elaborated more in the ''Minagoroshi'' sound novel.
* TheFakeCutie: [[spoiler:Acts like a cute CheerfulChild in public, but when alone with Hanyu or with her own thoughts she's very cynical.]]
* TheFatalist: [[spoiler:Years of being stuck in a gruesome GroundhogDayLoop]] has led Rika to believe YouCantFightFate and there's nothing she or anyone else can do about it. [[spoiler:Inspired by Keiichi, she keeps trying, though, and eventually gets it right.]]
* FriendshipFavoritism: Downplayed in a realistic fashion; Rika cares about all of her friends, but she has a closer bond to Satoko compared to the rest. The rest of the cast is aware of both the favoritism and its innocent nature but are not really bothered by it.
* GroundhogPeggySue: [[spoiler: Rika has been stuck in a GroundhogDayLoop for at least a century where she relives the last month of her life continuously. She is unable to break the loop until the end of the series.]]
%%* GuileHeroine
* HimeCut: Due to being a {{Miko}}.
* HiveQueen: It's noted that the older residents in the city are all incredibly fond of her. [[spoiler:This is due to a pheremone signal she releases for her "subjects". Though this is the extent of her power; she theorizes that the effect could have played the trope more straight in the past.]]
* IdenticalGranddaughter: She looks a hell of a lot like her ancestor Ōka.
* ImageSong: "Mugen Kairou", and "S A G A Rinne no Hate ni".
* ImmortalImmaturity: [[spoiler:While she says she's mentally hundreds of years old, it becomes clear that it's not true. Instead, she's actually grown desperate rather than truly growing old. This can also be explained by the fact that her body has not yet reached puberty, so her brain is not fully developed, and thus she simply cannot be completely adult in mind since she is not physically capable of it. While she does not act her apparent age (somewhere around nine to eleven) it's clear that she's really still pretty childish. Considering how she's spent hundreds of years hanging out with kids and teenagers and acting like a kid to fit it, it's also likely that she doesn't know ''how'' to act like an adult.]]
* JadeColoredGlasses: [[spoiler:In the first half of ''Minagoroshi''. You can't really blame her.]]
* JerkassFacade: In ''Saikoroshi-hen'', [[spoiler:after (possibly) being shunted in another world where her parents are alive and well, she reveals that she deliberately acted cold and affront to her parents as a means to cope with their deaths in every universe (as they don't listen to her warnings about eventually being killed by the Yamainu)]]. When it turns out in the same arc that [[spoiler:their dying would no longer be the case, Rika is able to renew her bonds with her parents. Especially her mother, who she is overjoyed to finally have a part of her life, and equally devastated when she learns that she will have to kill her to return to her original world and, upon awakening in said original world, that she just might have.]] Perhaps because of this, as of ''VisualNovel/UminekoWhenTheyCry'', [[spoiler:[[FaceHeelTurn it’s no longer]] [[FallenHero a facade]]]].
* LackOfEmpathy: [[spoiler:Some of her monologues in ''Minagoroshi'' make her appear not only cynical but also disturbingly selfish, only worrying about people's safety if that can allow her to survive (physically or mentally).]] The worst in all that? [[spoiler:She perfectly knows that the Mountain Hounds killed her parents and ''she doesn't even care'', since she considers it's her mother's fault for opposing the experiments in the first place.]] And in ''VisualNovel/UminekoWhenTheyCry'' [[spoiler:she’s downright ''[[TheSociopath evil]]'']].
* LadyDrunk: [[spoiler:A bit of a disturbing example. ReallySevenHundredYearsOld or not, she ''is'' physically a prepubescent girl. In large part it's a way for her to pick on Hanyu.]]
* {{Leitmotif}}: [[http://www.youtube.com/watch?v=oHU5C3uKYTM Baby's Walk]]; also used in some situations where a character ridicules himself without getting what's going on.
* LightFeminineDarkFeminine: Dark to Hanyuu's light.
* LittleMissSnarker: At first you may think her patting the head of people is to comfort them; you quickly realize it's her way of ''mocking'' them.
-->'''Satoko:''' Mion must have caught a cold, she looks a bit feverish. Hey, Rika, why are you patting my head?!\\
'''Rika:''' Satoko, you too will catch a cold someday.
* TheManyDeathsOfYou: Most of the time [[spoiler:she is disemboweled following the "gut drifting" ritual]]. But there are also worlds where [[spoiler:she is tortured to death by Shion, stabs herself not to be tortured to death by Shion, burns when Rena blows up the school, or is killed by Teppei when trying to save Satoko]]. And probably others in the early worlds when she actually tried to do something.
* MeaningfulName: Rika means ''Pear Blossom'' whose meanings are "lasting friendship and hope".
** This also created some sad meaning with [[VisualNovel/UminekoWhenTheyCry the sequel’s]] [[spoiler:Bernkastel]] as [[spoiler:Rika removes herself (Frederica) from "Frederica Bernkastel"]] which means that [[spoiler:Bernkastel [[FaceHeelTurn has lost all hope]].
* MentalTimeTravel: [[spoiler: By unusual means (using {{Alternate Universe}}s rather than actual TimeTravel), but ultimately to the same effect.]]
* {{Miko}}: She serves as one at Oyashiro-sama's shrine, and she also performs rituals at the Cotton-Drifting Festival.
* TheMindIsAPlaythingOfTheBody: [[spoiler:Due to still being physically a preteen, she cannot achieve complete mental maturity despite being mentally hundreds of years old, simply because certain changes in the brain that occur during puberty haven't occured for her yet. A line in the visual novel suggests she hasn't even gotten her first period yet.]]
* NotGrowingUpSucks: [[spoiler: In Matsuribayashi-hen, as part of her SurvivalMantra, she boasts that once the loop ends among most things, she's gonna grow taller and develop breasts.]]
* ObfuscatingStupidity: As part of her DeliberatelyCuteChild routine.
* OracularUrchin: Somewhat subverted. Rika often gives creepily ominous advices and warnings to the other characters, as if she can predict what is going to happen. [[spoiler:She doesn't "predict the future" so much as she "remembers" it because of the GroundhogDayLoop.]]
* OutOfContinues: [[spoiler:Unlike other examples of GroundhogDayLoop, the period of time she and Hanyu can rewind becomes progressively shorter, meaning that her attempt in ''Matsuribayashi'' was probably her last chance.]]
* OutOfTimeOutOfMind: [[spoiler:Averted, though she puts on an act so as not to freak people out.]]
* PrecociousCrush: Strongly implied towards Akasaka.
%%* PurpleEyes
* ReallySevenHundredYearsOld: [[spoiler:Technically, Rika would be a 700 year old in a little girl's body.]]
* {{Reincarnation}}: She's thought to be the reincarnation of Oyashiro-sama.
* RippleEffectProofMemory: [[spoiler:Along with Hanyu (who's the one responsible for the loop in the first place), she's the only person who knows that there's a GroundhogDayLoop going on, and she remembers all the previous universes.]]
* SaveScumming: [[spoiler: Each time she dies in one of the loops, she is sent back to the beginning of the loop. This has been going on for possibly over a thousand years. Not that it helps her much since she never fights enough to prevent everyone's deaths until the end of the series. Also, the period of time she and Hanyu can rewind becomes progressively shorter and by the final loop Rika can no longer remember the events of the latest loop.]]
* SayingSoundEffectsOutLoud: She has a habit of doing this, such as saying "pachi pachi" ("clap clap") while clapping. Her "nipa~" VerbalTic is essentially this as well, since "nipa" is a Japanese UnsoundEffect for smiling.
* SilkHidingSteel: Underneath her cute and girly persona is a serious and snarky temper.
* StepfordSmiler: In a cast full of them, she's probably got it the worst; she acts like a cute CheerfulChild, but in reality she's [[spoiler:suppressing how she's witnessed and experienced hundreds of years' worth of murder and torture]].
* TheStoic: When she's not her usual self.
* SupportingProtagonist: Shares the status with Keiichi. [[spoiler:Basically, the whole story is about her and the latter half is frequently from her perspective, but despite this, it is mostly Keiichi and the rest who act to save Rika from her fate.]]
* TaremeEyes: When in her "cute" facade, otherwise they're [[TsurimeEyes not]].
* TomboyAndGirlyGirl: Girly Girl to Satoko's Tomboy but Tomboy to Hanyuu's Girly Girl.
* TookALevelInIdealism: [[spoiler:After having pretty much given up on fighting fate and resigning to keep dying continuously, Rika is inspired by Keiichi to not give up and keep trying. She eventually gets it right and frees herself from the loop.]]
* TrademarkFavoriteFood: [[spoiler:Bernkastel Wine.]]
* TroublingUnchildlikeBehavior: [[spoiler:She drinks wine to [[DrowningMySorrows drown her sorrows]] and she's not any older than twelve (at least, not physically).]] She does this behind everyone else's backs, though.
* TsurimeEyes: In her "mature" form.
* VerbalTic: "Mii", "Nipa~"
** The "nipa~" could actually be [[spoiler: foreshadowing of somesort. Turns out, "nipa~", as well as being the Japanese onomatopoeia for "smiling", is also the name of [[http://en.wikipedia.org/wiki/Henipavirus a virus that causes neurological failure and death in humans.]] ]]
** Like Hanyu, she ends all her sentences with "desu" or "nano desu", even when it makes no gramatical sense.
* VocalDissonance: [[spoiler:Her "real" voice, when she's not ObfuscatingStupidity, sounds deeper and more mature than someone her apparent age would sound.]]
* WeaponOfChoice: [[spoiler:Satoko's Hinamizawa Syndrome medication]], and strangely enough, a mop.
* WithFriendsLikeThese: She and Hanyu are close friends, no doubt about it; that doesn't prevent her from regularly punishing Hanyu with wine and spicy food or outright shutting her up when she finds her annoying.
* YaoiFangirl: In the preview at the end of Kai episode 7 she claimed that she ships [[CrackPairing Keiichi/Ooishi]].
* YoungerThanSheLooks: Her true personality makes her seem adult-like.
* YouGottaHaveBlueHair: Her hair is blue, though the anime gives it a more purple tint.

!!!Voiced by: Creator/YuiHorie (JP)
The mysterious "transfer student" in ''Matsuribayashi-hen''. She has appeared to Rika all her life, but only in ''Matsuribayashi-hen'' does she choose to interact with others. She is very meek and often makes the noise "Au au au" when she is nervous or uncomfortable. She dislikes alcohol and spicy foods like kimchi, which Rika uses in large amounts when Hanyu is being particularly annoying (Hanyu's and Rika's senses are linked together).

The eighth arc, Matsuribayashi-hen (Festival Music chapter), is focused on her.

* AdaptationalCurves: Her ghost form has a more adult appearance in the manga, making her considerably more busty.
* AllLovingHeroine: She is all about love and forgiveness. Even people she professes to hate, like [[spoiler:Takano]], she is willing to forgive and even sacrifice her life for when it comes down to it.
* ApologisesALot: "Gomen nasai..."
* AscendToAHigherPlaneOfExistence: [[spoiler:She was originally a demon in human form who ascended to godhood by dying for the sins of others.]]
* {{Bokukko}}: Uses "boku" as a first-person pronoun, despite not being tomboyish at all. According to her, that's because [[spoiler:in her time (she is 1000 year old after all) boys and girls didn't speak differently]].
* BreakTheCutie: Quite a lot, though often missed in the anime adaptation or replaced with a more cute reaction.
* TheCameo: She appears in a single panel in the manga version of Episode 6 of ''VisualNovel/UminekoWhenTheyCry'' [[spoiler:as the GameMaster who trapped Bernkastel/Rika in a hellish {{Unwinnable}} game]].
* CantHoldHerLiquor: A fact that Rika likes to take advantage of.
* ClapYourHandsIfYouBelieve: [[spoiler:The reason why her powers are failing lately.]]
* ContinuitySnarl: [[spoiler:At the end of ''Matsuribayashi-hen'' (the conclusion of the main storyline) and in the later ''Yumeutsushi-hen'', Hanyu stays as a physical being... but in the in-between chapter ''Saikoroshi-hen'', she's suddenly a spirit again. This is never explained, though the visual novels have implications that she can willingly transition between being physical and being incorporeal.]]
* CurtainsMatchTheWindow: Purple hair and eyes.
* CuteGhostGirl: Before ''Matsuribayashi''.
* CuteMonsterGirl: [[spoiler:Before she became a god, she was a demon who took on human form but couldn't hide her horns. What a "demon" actually is is left vague. In ''Matsuribayashi-hen'' Rika confesses to her that no matter how many times Hanyu has explained who she is and where she came from, she can never understand it.]]
* DarkAndTroubledPast: [[spoiler:She was forced to kill her husband who was "possessed" by pure-blood demon to save him. She also had her daughter kill her to prevent her from turning "evil" again.]]
* DeathByAdaptation: [[spoiler:In Miotsukushi-hen, the new ending for the [=PS2=] port.]]
* DeityOfHumanOrigin: [[spoiler:She was originally a demon who took human form and was sacrificed as a scapegoat in order to "atone" for the village's sins. After dying, she ascended to godhood.]]
* DeterminedDefeatist: [[spoiler:In a slightly different manner from Rika. While Rika has a tiny sliver of hope that the perfect circumstances may line up, Hanyu is only doing it because she wants to spend more time with Rika.]]
* DoesNotLikeSpam: Wine and spicy food.
* FreakinessShame: She has something of a complex about her horns. Rena thinks they're cute (but then again, Rena thinks a lot of things are cute). The only one to react negatively is Takano, and even she probably didn't really care. It's implied that her complex comes not from her current-day friends' reactions (or lack thereof) but rather the fact that [[spoiler:when she took on human form to mediate between demons and humans, she could not hide her horns. They are a large part of the reason why she was chosen as a sacrifice]].
* GodIsGood: [[spoiler:She’s the BigGood of the story, despite initial impressions.]]
* GodsHandsAreTied: [[spoiler:In fact, she even goes so far as to describe herself as "a powerless god".]]
* GodWasMyCopilot: [[spoiler: She's Oyashiro, and, in spite of her InUniverse HistoricalVillainUpgrade, is the reason Rika can utilize MentalTimeTravel]].
* GoingCommando: In her {{Miko}} outfit. Ironic given that her adult form's garb is much more conservative.
* HistoricalVillainUpgrade: InUniverse; [[spoiler: She's [[DiscOneFinalBoss Oyashiro]], who's known as a god of torture and bloodshed]].
* HornedHumanoid: She has a pair of dark-colored horns on her head, one which is chipped slightly. [[spoiler:It turns out that she used to be a demon whose horns remained when she took human form. Her horns were largely the reason why she was sacrificed, since many people feared and distrusted her because of them.]]
* ImageSong: "Nano Desu".
* ImmortalImmaturity: Generally, she can act and sound like a thousand-year old goddess when she is serious, even calling [[spoiler:Takano]] "child of man" at the end of the last arc. She actually seems to have the same kind of dual personality as Rika. The same voice actress voices her "child" and "adult" voices. In addition, she demonstrates some stunning immaturity by refusing to so much as apologize for [[spoiler:stealing Tamura's offering, even though that minor transgression is what motivated Tamura to let Une's threat spread to a global scale]]. DisproportionateRetribution or not, what Hanyū did in that moment was wrong and yet she still can't bring herself to even say sorry to someone [[spoiler:who put the whole world in danger]].

* InterspeciesRomance: In life, [[spoiler:Hanyu was a demon who took human form. She married a human man and they had a daughter together]].
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=wqpPqPhyjuo "Over the sky"]] represents the "Goddess" part of her character. Really makes you feel like you are hovering above the clouds. The human part is represented by [[http://www.youtube.com/watch?v=6jM5OslNI3w&feature=endscreen&NR=1 "Air Pizz"]].
* LightFeminineDarkFeminine: Light to Rika's Dark.
* MayflyDecemberRomance: According to Kotohogushi-hen, Hanyu first met her husband [[spoiler:when he was just a baby]]! Added to the fact that she's mentioned to be "long-lived" and this is in full effect.
* MessianicArchetype: Subverted. Hanyu was one in the past, [[spoiler:allowing herself to be killed by her own daughter to initiate the first Watanagashi Festival to atone for the sins of the inhabitants of Hinamizawa]], but now disagrees with the idea of people sacrificing others in the name of purifying their own sins.
* {{Miko}}: She wears a miko outfit in her spirit form.
* MisappliedPhlebotinum: [[spoiler:For every arc until the last she is undetectable to anyone that is not named Rika or in the later stages of Hinamizawa syndrome. [[FridgeLogic It apparently never occurred to Rika to utilize her invisible ghost spy to do anything like figure out who killed Tomitake]]. Then again, Rika is still quite the child, even though it sometimes seems otherwise. And quite pessimistic at that, with the whole "what's the point" attitude since she can never seem to alter some events.]]
* NeverMyFault: Downplayed in ''Higurashi Hou''; while the situation [[spoiler:with Une and Tamura]] is clearly more their fault than her own, Hanyū stubbornly refuses to take any sort of responsibility for her role in [[spoiler:Tamura]]'s backstory. While it's true that [[spoiler:Tamura]]'s actions are major DisproportionateRetribution of the highest degree and petty in their intent, Hanyū always tries to shift all of the blame on her when the more mature thing to do would probably be to apologize for her own (admittedly minor) wrongdoing against [[spoiler:Tamura]].
* NewMeat: After she joins the club, Mion calls her the "newbie".
* NewTransferStudent: Apparently to the other classmates who don't know her true identity.
* NiceGirl: Contrary to how others perceived Oyashiro, Hanyuu is a sweet and selfless girl.
* NotSoImaginaryFriend: She has appeared to Rika all her life and Rika thought she was just her ImaginaryFriend. When she was growing up, Rika's mother was bothered by her "imaginary friend" Hanyu. Not helped by the fact that Hanyu taught her to cook and do laundry.
* OnlyKnownByTheirNickname: Most people call her [[spoiler:Oyashiro-sama]], people who know her call her Hanyu, but her real name is [[spoiler: Hainiryūn Ieasomūru Jieda. She got the nickname of Hanyu because her husband could not memorize her full name.]]
* OurDemonsAreDifferent: [[spoiler:She's a demon who took on human form, though what a demon really is in this setting is left very vague; Rika mentions that she still doesn't understand what a "demon" is even after Hanyu explained it to her.]]
* OurGodsAreDifferent: [[spoiler:She was a demon in human form who was sacrificed and ascended to godhood after dying. She's currently worshiped in a similar manner to most Shinto gods in real life, though her reputation has been distorted over the centuries so that now everyone sees her as a malevolent force who will curse anyone who displeases her. She isn't too happy about that.]]
* OverlyLongName: [[spoiler: Hainryun Ieasomuru Jieda.]]
* ParentalSubstitute: A weird example. She replaced Rika's mother in teaching her cooking, sewing and so on, while the latter was ''alive and living with her''. Naturally, her real mother was pretty freaked out and upset to see her daughter talk with a NotSoImaginaryFriend ''and'' do things she never taught her. [[spoiler:Probably not made better by the fact that as soon as Rika was born the villagers started adoring her instead of her mother.]]
* PhysicalGod: [[spoiler:But only in ''Matsuribayashi-hen''. It appears to be a significant step down on the power scale.]]
** [[spoiler: Played straight in the ''Daybreak'' doujin games; compared to the rest of the cast that uses whatever weapons/tools/toys they could get their hands on, Hanyu wields actual (powerful) magical energy blasts of varying types.]]
** [[spoiler:In the visual novel she can switch between forms, she turns into her spirit form at least once during Matsuribayashi-hen, and there's the fact that Keiichi's father can see her when they are attracting the Maebara familty to Hinamizawa, this too implies she can switch at will. She probably stayed in spirit form in most worlds because she had yet to step onto the stage.]]
** [[VisualNovel/UminekoWhenTheyCry It’s implied that]] [[spoiler:Featherine, who plays this straight, is her true self]].
%%* PurpleEyes
* ReallySevenHundredYearsOld: [[spoiler:As the origin of the Oyashiro-sama legend she's around a thousand years old. Even older when you factor in the [[GroundhogDayLoop Groundhog Day Loops]]. Not to mention her not even being in [[VisualNovel/UminekoWhenTheyCry her true form]] either.]]
* RedEyesTakeWarning: The few times she is seen legitimately angry.
* ShipperOnDeck: She teases Rika quite a bit when Akasaka comes to her home [[spoiler:to occupy the house while she and Satoko are hiding at Mion's place.]] As a response, Rika eats dinner with Akasaka; [[FunnyMoments a super-spicy dinner]].
* ShrinkingViolet: She's incredibly shy around other people at first, but she gradually opens up.
* SilentScapegoat: [[spoiler:As part of the deal to allow her people to live in Hinamizawa, Hanyu allowed herself to be set up as a scapegoat and killed by Ōka via ritual butchering. As her daughter was also the daughter of one of the village priests, this brought unity to the two factions.]]
* SilkHidingSteel: Don't underestimate her just because she's sweet and girly! She's the reincarnation of Oyashiro-sama for God's sake.
* SomeCallMeTim: Her real name is so long that [[spoiler:her husband]] had trouble remembering it and shortened it to her current name, Hanyu.
* SpiritAdvisor: Though when it comes down to it she's not a very good one, since the only "advice" she gives Rika is to not let her hopes up to avoid disappointment. This only served to make Rika more cynical.
* SupernaturallyYoungParent: [[spoiler:In life, she had a husband and a daughter. However, she was already an adult when she died, and only appears as a young girl in the present as a way to get Rika to relate to her.]]
* SweetTooth: She loves sweets, especially cream puffs.
* {{Synchronization}}: Her senses are connected to Rika's. Though it's PlayedForLaughs rather than drama, with Rika threatening to eat spicy food and drink alcohol whenever Hanyu annoys her.
* TagalongKid: Even before [[spoiler:the group aside from Rika could see her]].
* TimeMaster: [[spoiler:Can stop time primarily in the manga version, though it is only really good for speaking because when she stops time not only do bullets stop moving, but so do people. She's also the one responsible for sending Rika back in time each time.]]
* TomboyAndGirlyGirl: Girly Girl to Rika's Tomboy.
* TrademarkFavoriteFood: Cream puffs.
* UnusuallyUninterestingSight: Subverted. The games reveal that everyone ''did'' notice her horns but avoided mentioning them because they either were [[IgnoreTheDisability too polite]], [[FreakyIsCool they liked them]] or they thought they were some kind of accessory.
* VerbalTic: "Au au auu~" and "Nano desu"
* TheVoice: Until ''Minagoroshi-hen'', she only appears in the form of a mysterious voice. In ''Onikakushi'', in at least the sound novel remakes, you can hear her in the scene where Keiichi looks out his window at Rena. It's scary.
* WalkingSpoiler: Her being [[spoiler:Oyashiro, and [[GoodAllAlong not being the]] BigBad as we were led to believe]].
* YouGottaHaveBlueHair: Hers is purple.

!!Supporting Characters
[[folder:Satoshi Houjou]]
!!Satoshi Houjou
!!!Voiced by: Creator/MitsukiSaiga (JP - drama CD), Creator/YuuKobayashi (JP - anime), Creator/DarrelGuilbeau (EN)
Satoko's older brother, who disappeared a year before the story began.
* BigBrotherInstinct: Subverted - while he was ''very'' protective of Satoko, a repressed part of him was also tired of protecting her from their aunt and hearing her constant whining.
* {{Bishonen}}: Quite handsome along with Keiichi.
%%* BreakTheCutie
* ChekhovMIA: [[spoiler:He's in a coma in Irie's clinic.]]
* ChekhovsGunman: His disappearance is a major part of what sets off the killers in three of the four question arcs fueling Keiichi's paranoia (Onikakushi), Shion's grief (Watanagashi and Meakashi) and Keiichi's protectiveness (Tataragoroshi).
* ConvenientComa: [[spoiler:Subverted to an extent. It means he's not dead, but he's still sick at the end of the story. He'll be kept in the coma at ''least'' until there's a real cure.]]
* {{Foreshadowing}}: From Frederica Bernkastel's poem in ''Meakashi-hen'': "How many years will pass before she wonders if she really dropped them?"
* IllBoy: According to Dr. Irie, he was frail due to a heart condition.
* ImageSong: "Yellowsick". Ironically, he has one of the most energetic and hot-blooded image songs of the cast.
* KnightTemplarBigBrother: [[spoiler:He killed his aunt in order to protect Satoko. In large part it was due to Hinamizawa syndrome, though.]]
* TheLostLenore: To Shion.
* NiceGuy: Usually nice and kindhearted, even moreso than Keiichi.
* PromotionToParent: For Satoko.
* TechnicolorEyes: Pink.
* WouldHitAGirl: He hits Shion, although justified since he did it to save his sister Satoko from her beatings.

[[folder:Kuraudo Ooishi]]
!!Kuraudo Ooishi
!!!Voiced by: Creator/{{Chafurin}} (JP), Joe [=DiMucci=] (EN)
A veteran police investigator at Okinomiya who has vowed to solve the mystery of the Hinamizawa murders before his retirement, due to personal reasons. Due to his uncouth tactics and the lengths that he goes to in order to solve the mystery, he is looked upon as a nuisance by the villagers. He approaches one of the main characters to become his informant in several arcs, and is sometimes unwittingly responsible for triggering their paranoia.
* DirtyOldMan: It's more apparent in the manga and VNs, but he really does have a strong interest in porn.
* {{Foil}}: Old, perverted, and usually implementing a very signature brand of ObfuscatingStupidity, to Akasaka's more young, straightlaced, and straightforward persona. He also foils a little bit against Kumagai, his relatively straightlaced assistant who is much calmer and better at negotiation, whereas Ooishi intentionally puts people off with his brash attitude.
* GallowsHumor: There's a bit of an on-going dark joke between Ooishi and anybody he has visiting to investigate the Tomitake murder where he'll end a conversation with, "Have a nice year!" in reference to the serial Watanagashi murders. It shows up repeatedly in the Onikakushi-hen TIPS.
* InspectorJavert: He's usually right, though, like in [[spoiler:Tatarigoroshi-hen]] and [[spoiler:Onisarashi-hen]]. [[spoiler:But he's completely wrong in the most important way in that he thinks the Sonozaki's are behind everything. This keeps him from approaching the only person in the group that never goes insane.]]
* IntergenerationalFriendship: With Asakasa in ''Himatsubushi-hen'' and [[spoiler:Keiichi]] in ''Minagoroshi-hen''.
* KnightOfCerebus: In most arcs, he signals the end of comedy, or a [[FromBadToWorse sharper dive into tragedy]], not always in his first appearance, but in his first confrontation with the arc's protagonist. Lampshaded by Dr. Irie.
* ItsPersonal: The dam construction manager who was the first murder victim was a {{Mentor}} to him. Once he finds out he was murdered and suspects the Sonozakis of it, he becomes determined to crack the case. [[spoiler:However, as noted, this actually works against him because he starts looking for links between events that just aren't there, which impedes his effectiveness.]]
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=8HN8tmCoKwM "Big Bear".]] Also, "Dancers 5" in ''Himatsubushi''.
* MentorArchetype: The "old man". Ooishi's father died in a bombing just after the end of World War II, and Ooishi spent the few years after that reluctantly arresting starving people who bought rice on the black market. While he was chasing one, a guy who looked just like his father punched him and [[TheReasonYouSuckSpeech scolded him in front of everyone.]] He started to consider that man as a second father.
* MyGreatestFailure: His inability to solve the Hinamizawa murders [[spoiler:and the eventual disaster that almost inevitably befalls the village]] serves as this for Ooishi in most of the endings.
* NotSoDifferent: In Tsumihoroboshi-hen, the narration notes that the way that Ooishi operates is actually pretty similar to the stereotypes of the {{Yakuza}}, embodied in the story by his [[ArchEnemy Arch Enemies]], the Sonozaki family.
* ObfuscatingStupidity: His drawling accent, casual manner and crude humor put people off their guard. Unfortunately, it makes him come off as arrogant and causes distrust in him.
* OddFriendship: With Keiichi in ''Minagoroshi-hen'' and Akane Sonozaki in ''Matsuribayashi''.
* ReasonableAuthorityFigure: In most of the arcs.
* {{Retirony}}: In the arcs where he is killed, due to the short time limit that he has to solve the case before he retires.
* SignatureLaugh: Nfufufufu!
* UnwittingInstigatorOfDoom: He doesn't realize it, but his actions frequently wind up just making a given arc worse and making it so that there's really no one sane left for [[spoiler:Rika]] to get help from. Particularly egregious in [[spoiler:Onikakushi-hen]], where he's arguably the ''cause'' of [[spoiler:Keiichi]] going off the deep end, but he also exacerbates [[spoiler:Keiichi's and Rena's]] jumps off the cliff in Tatarigoroshi-hen and Tsumihoroboshi-hen, no matter how much help he might turn into near the end of the latter. And his consistent mistrust of the Sonozakis makes it impossible for anyone to trust [[spoiler:the one reliably sane person]] in the group.

[[folder:Jirou Tomitake]]
!!Jirou Tomitake
!!!Voiced by: Creator/ToruOkawa (JP), Creator/KyleHebert (EN)
A freelance photographer who comes to Hinamizawa occasionally. He gets along well with Miyo Takano because of their similar interests in photography. Despite being only an occasional visitor, he seems to know a fair amount about Hinamizawa's past. Ooishi and the police are suspicious of his identity.

In the first six arcs, he is consistently found dead of suicide on the night of Watanagashi, triggering many of the events that follow.
%%* CurtainsMatchTheWindow
* DarkAndTroubledPast: One of the very rare recurring characters who ''doesn't'' have one.
* DesignatedVictim: Like Takano, in most arcs, he is found dead on the night of Watanagashi.
* DrivenToSuicide: [[spoiler:In most of the arcs due to being injected with H173.]]
* EmbarrassingNickname: [[spoiler:Irie calls him "Risa-san"]] As a subversion, this conveniently serves to hide their connections to the reader in the early arcs.
* {{Foreshadowing}}: He can hear [[spoiler:Hanyu's fuss]] in the shrine storage. Meaning that [[spoiler:he was already at least at level 4 of the Hinamizawa syndrome at that time.]]
* FriendlySniper: He's a good guy whose also a skilled sniper.
* ImprobableAimingSkills: [[spoiler:Called out on this by the Mountain Hounds when sniping on a moving vehicle while on rough terrain.]]
* LoveMartyr: [[spoiler:Especially evident in ''Matsuribayashi-hen''.]]
* NiceGuy: His most defining trait is just how kind he is.
* ObfuscatingStupidity: [[spoiler:He's a veteran sniper.]]
* OfficialCouple: With Takano. [[spoiler: Yes, even after she tries to kill him.]]
* OnlyKnownByTheirNickname: It's mentioned in several arcs that Jirō Tomitake is not his real name, but we never learn what it is.
* WeaponOfChoice: Camera. [[MemeticMutation "TOMITAKE FLASH!!!!"]] [[spoiler:His weapon is actually a sniper rifle.]]
* WeHardlyKnewYe: He usually dies too early to get any kind of development.

[[folder:Miyo Takano]]
!!Miyo Takano[[spoiler:/Miyoko Tanashi]]
!!!Voiced by: Creator/MikiIto (JP), Creator/FuyukaOura (JP - young), Creator/KarenStrassman (EN)
A nurse at the village clinic who has a keen interest in Hinamizawa's past and culture, recording all her speculation in notebooks. At times, her storytelling can be very mysterious and chilling, and [[TheGadfly she seems to enjoy putting people on edge]]. Unlike the other villagers, she opposes the almighty Oyashiro-sama. In the first six arcs, she consistently disappears on the night of Watanagashi, and an incinerated body thought to be hers is found in the mountains.

* AGodAmI: [[spoiler:The end of ''Minagoroshi-hen''.]]
** Specifically, [[spoiler:it was influenced by a metaphor from her grandfather, saying that if his research proves fruitful his legacy will live forever, like that of a god.]] Fast-forward to modern day and Miyo [[spoiler:raves about how if she proves her grandfather's research is true, and re-inspires fear of Oyashiro-sama in the process, she will in effect '''''become''''' Oyashiro-sama and live forever with her grandpa.]]
* AntiVillain: [[spoiler:An interesting take on a [[SlidingScaleOfAntiVillains Type II]]. Exposing the truth about the Hinamizawa Syndrome for the sake of her adopted Grandfather's legacy, someone whom she viewed as a savior, is hardly what you could call "evil." But with the abuse she took in the OrphanageOfFear before being adopted and the subsequent repeated brushing off of her Grandfather's research, desperation and insanity take hold and drive her to do gradually less savory acts in pursuit of her goal.]]
* AttackAttackAttack: Lampshaded [[PlayedForDrama in a serious manner]]. [[spoiler:She keeps sending in the Yamainu to attack an entrenched enemy on their territory no matter how many casualties they take nor how demoralized they are. Any sensible commander would have done a tactical retreat to regroup at the very least.]]
* [[spoiler:BeingTorturedMakesYouEvil: The consequence of being tortured into pretty much ''insanity'' in the OrphanageOfFear from her childhood. It's heavily implied that she suffers from severe PTSD as a result.]]
* [[spoiler:BigBad: Is revealed to be this toward the end.]]
* [[spoiler:BitchInSheepsClothing: A kind nurse until it was revealed that she is the main villain.]]
* BreakTheCutie / BrokenBird: Her backstory.
* [[spoiler:TheChessmaster: She's behind everything.]]
* [[spoiler:CuteAndPsycho: Acts pleasant on the surface, but she's actually responsible for much of the chaos in the story. Is it really any surprise?]]
* DeadlyDoctor: Although she's always one of the first two victims of Watanagashi, she isn't quite so helpless as you'd think. [[spoiler:Especially since she isn't ''really'' a victim]]. Plus, her weapons of choice in ''Higurashi Daybreak'' are syringes.
* DesignatedVictim: Like Tomitake, in most arcs she goes missing on the night of Watanagashi, and is later found dead. [[spoiler:Subverted, since she was faking her death]].
* DissonantSerenity: To contrast all other [[AxCrazy infected]] [[UnstoppableRage ones]].
* DrowningMySorrows: After she learns that the research will be stopped, [[spoiler:indicating that she has crossed the DespairEventHorizon.]]
* EarlyBirdCameo: Right near the start of the very first chapter of the game, Onikakushi, you come across Miyo when Rena and Mion are showing Keiichi around Hinamizawa. She's simply mentioned as the third of three people (along with two extras) the trio run into who is named and briefly described by the girls to demonstrate how everyone in Hinamizawa know all about everyone else- she doesn't even make an on-screen appearance or have any lines ascribed to her. Except in the manga version, where she ''does'' make a physical appearance.
* EasilyForgiven: By Tomitake in the realities where he lives, even though [[spoiler:she attempted to kill him. Seeing her in a defeated, pathetic state probably helps, it's difficult to hate someone in that position. Not to mention that Tomitake is more aware of Takano's sad past and motivations than other characters.]]
* EpilepticTrees: A perpetuator of these in-universe. They range from the clearly correct (the prevalence of the "oni" character in the Sonozaki and Kimiyoshi family names), to the plausible but unprovable (the possible alternate spelling of "Oyashiro"), to the clearly insane (a UFO crashed in the swamp and Oyashiro was an alien doctor!). [[spoiler: These trees are her tactic of choice in [[{{Troll}} her trolling the cast]]]].
* EvilLaugh: Like [[DysfunctionJunction most of the characters]], she gets one at some point. [[spoiler:A truly epic one when she's revealed to be the BigBad.]]
* [[spoiler:FakingTheDead: In every arc.]]
* FreudianExcuse: The reason she’s so adamant about opposing [[PhysicalGod Oyashiro-sama]]? [[spoiler:After losing her parents, she had to live in a hellish OrphanageOfFear. She was rescued from the orphanage and raised by a loving, kindly old man and now wants to prove his research, not matter what. Unfortunately, the trauma she already had from the orphanage led to her taking a few things that her grandfather said the wrong way, which, combined with people treating her grandfather's thesis as garbage, as well as her underlying selfishness and 'us-vs-them' mentality, led to her becoming a heartless monster.]]
* FromNobodyToNightmare: From sweet kid to BreakTheCutie to friendly but detached nurse [[spoiler:to [[TheSociopath sociopathic]], murderous researcher.]]
* GenreBlindness: [[spoiler:Boy, does she ''ever'' catch a case of it in the end. Alluded to in AttackAttackAttack above, while the entrenched enemy in question is [[JustAKid a group of schoolchildren]], they also happen to be [[TheHero the protagonists]]. Who also have a sort-of-PhysicalGod on their side ''[[VillainBall whom Takano had actually met with and thus KNEW would be acting against her at the start of the arc]]''. Failure to acknowledge any of this leads to her downfall.]]
* GoodEyesEvilEyes: [[spoiler: One of the indicators that she's not the innocent victim she appears to be.]]
* HappilyAdopted: After [[spoiler:some ''very'' nasty experiences at her OrphanageOfFear]], she was adopted by Hifumi Takano and was able to live a relatively happy life with him until he died. [[spoiler:Unfortunately the trauma from her time at the orphanage eventually caught up with her, and she became willing to go to extreme methods to continue her adopted grandfather's research...]]
* HeelFaceTurn: [[spoiler:But only in the very end of the series. And in later arcs she continues to terrorize the heroes.]]
* HospitalHottie: Her outfit consist of a really short skirt and a pair of [[ZettaiRyouiki high black stockings]]. [[spoiler:Rare [[EvilIsSexy evil]] example, at that.]]
* ImageSong: "Bon Karma".
* IronicEcho: Not exactly a quote, but the scene near the end of ''Matsuribayashi-hen'' where [[spoiler:her bullet misses Hanyu]] very closely echoes the scene near the beginning of the arc where [[spoiler:"God"'s lightning bolt narrowly misses Takano, immediately after she asks God to either give her a better life or kill her. Since she was spared, she took this as a sign that she is meant to live, and as a result, she became something of a Determinator]]. It can be interpreted that [[spoiler: her bullet missing Hanyu is a sign that Rika and Hanyu's determination to live has finally reached the same level as Miyo's will to live on that day.]]
** [[spoiler: It didn't miss on purpose. [[CompressedAdaptation Although the anime does not show this]], Hanyu stops time and realizes that the bullet won't miss. Then Rika starts moving, despite time being stopped, and ''grabs the bullet'', moving it so that it won't hit anyone.]]
* [[spoiler:KarmaHoudini: Hello, she tries to kill an entire village over and over again, and what does she get? Treatment for a disease that it wasn't well-established she had (though current evidence points to yes) and a good cry in her lover's arms. While in that chapter she didn't manage to kill anyone, she's still responsible for the death of Rika's parents and generally being an amoral researcher.]]
** [[spoiler:It's particularly JustForFun/{{egregious}} in the worlds where Rika fails, and she succeeds in murdering everyone in Hinamizawa and gets away with it scot-free.]]
*** [[spoiler:Although, if she actually has Hinamizawa Syndrome, she bound to go crazy(er), and die by shratching her throat out.]]
** It actually makes sense in context a bit with [[spoiler:Hanyu offers to forgive Takano of all her sins. [[TheFarmerAndTheViper Then she tries to kill Hanyu.]]]]
* [[spoiler:ManBehindTheMan: To the Sonozaki family, the Yamainu, and the false image of [[DiscOneFinalBoss Oyashiro-sama]] she created.]]
* [[spoiler:ManipulativeBitch: The biggest in the series. She manipulates Keiichi, Rena, and Shion with both her scrapbooks, the Oyashiro Curse and faked her own death in order for them to succumb to Level 5 and throw a giant suspicion on the Sonozaki Family.]]
* MeaningfulRename: After being adopted by Hifumi Takano, she changes the kanji in her name to follow his NumericalThemeNaming.
* MentorArchetype: Her main role in the story before [[spoiler:being revealed as the BigBad]] is to inform the heroes of the legends of Hinamizawa and help them in defeating the conspiracy.
* MilkmanConspiracy: [[spoiler:BigBad or not she's still just a nurse when it comes down to it.]]
* NaughtyNurseOutfit: Irie once notes that since she is a doctor she isn't supposed to wear a nurse outfit (with an impressive ZettaiRyouiki to boot), but she does just for the hell of it. Mion and Shion also tease her and Tomitake about their "foreplay" with that kind of outfit.
* NayTheist: She studies myths, religion, and the occult, but doesn't actually believe in any of them. In fact, she ''hates'' the local god Oyashiro-sama and will do anything to bring them down, in part because of her DarkAndTroubledPast.
* NoblewomansLaugh: Gets a classic one in the anime [[spoiler: after her AGodAmI speech]], yet it's somehow less disturbing than most of the protagonists' laughs.
* NotQuiteTheRightThing: [[spoiler:Just before the Final Operation, she realizes that because of her obstination to continue the research on Hinamizawa Syndrome, instead of staying in history, her grandfather's research is going to be erased and forgotten, whether a cure is found or the Manual 34 is implemented]]. She is the only one who regrets it though.
* NumericalThemeNaming: The kanji for her name uses the kanji for three (三) and four (四). [[spoiler:Just like how her adoptive grandfather's name is written as one (一), two (二), three (三).]]
* NiceHat: Her nurse's cap. Also, [[spoiler:her ''epic'' special forces beret.]]
* NightmareFetishist: Over the legends of Oyashiro-sama.
* OfficialCouple: DoubleSubverted with Tomitake. In the first season, they merely look like an OddCouple. [[spoiler:After ''Minagoroshi'', one can think Takano was merely playing Tomitake and that he was the only one in love. But the following arc shows she genuinely loves him and isn't really eager to kill him.]]
* OrphanageOfFear: She was sent to one of these after her parents died, witnessing and suffering lots of horrors there. [[spoiler: She got so throughly broken that she went INSANE and became the BigBad with time.]]
* PluckyGirl: Enough will to [[spoiler:alter fate itself]].
* PsychopathicWomanchild: Despite many characters describing her as a mature adult woman, her personality is actually frighteningly childish.
* SmiteMeOhMightySmiter: [[spoiler:She challenges God to give her a better life or kill her. A subsequent lightning bolt narrowly misses her.]]
* SoftspokenSadist: She enjoys making people uncomfortable in casual conversation, typically with her lurid fascination with the curse. Soon after introducing herself to Keiichi, she advises him to come to her clinic so she can give him [[AfraidOfNeedles BIG shot]] [[spoiler:foreshadowing her PlayingWithSyringes and other overt sadism]].
* [[spoiler:{{Troll}}: She manipulates several characters into going paranoid and berserk out of sheer amusement.]]
* TheUnfettered: [[spoiler:She is capable of doing pretty much anything, no matter how heinous.]]
* UnwittingInstigatorOfDoom: [[spoiler:Whether it's intentional or not, she's partially responsible for causing Rena and Shion to go off the deep end by giving her the scrapbook.]]
* UsedToBeASweetKid: [[spoiler:The sweet girl who collected flags and loved to go out with Dad and Mom? Yeah, she grew into a horrible bitch after she was tortured in the orphanage. Although she still was a sweet child when with Dr. Takano, and it's only after his death ''and'' his research is mocked that she goes off the deep end.]]
* [[spoiler:VillainousBreakdown: Started in Matsuribayashi-hen when Rika was falsely reported as dead for 48 hours and it just got worse after she was beaten.]]
* [[spoiler:VillainWithGoodPublicity: To most of Hinamizawa, she’s a kindhearted nurse with a weird hobby. She’s actually the direct leader of the MilkmanConspiracy controlling the town.]]
* WalkingSpoiler: Her past [[spoiler:(and the fact that she is the BigBad)]] makes her this.
* [[spoiler:WoobieDestroyerOfWorlds: Oh yes.]]
* WouldHurtAChild: [[spoiler:A woman who ''disembowels'' a little girl? After executing her friends? Holy crap.]]
* ZettaiRyouiki: As part of her nurse uniform.

[[folder:Kyousuke Irie]]
!!Kyousuke Irie
!!!Voiced by: Creator/ToshihikoSeki (JP), Creator/DaveMallow (EN)
The head doctor of the village clinic. Initially interesting in being a doctor just for the money, he became devoted to the field of psychosurgery after a head injury changed his father's personality. Despite his young age and the fact that he has a severe maid fetish, he is highly respected in the community. He cheerfully makes house calls and seems to truly care about everyone's health. He has (half-jokingly) admitted that [[TheJailbaitWait he wishes to marry Satoko when she is older]], but is not above chasing after Rika when she is wearing one of the uniforms from the restaurant ''Angel Mort''. In addition, he is the manager of the village's baseball little league team, the Hinamizawa Fighters.

* {{Bishonen}}: He's noted to be quite good looking.
* ComedicLolicon: He tends to express an attraction towards Satoko (and sometimes Rika), and it's always PlayedForLaughs.
* CreepyPhysical: To quote Irie, "It's good to be a doctor... because I get to touch the skin of young people many times, and I can turn them into my slaves with a little injection." Off-putting sense of humor for a doctor.
* CurtainsMatchTheWindow
* DeadlyDoctor: [[spoiler:He performed psychosurgery on unwilling patients in the past, although he had good intentions. Patient consent wasn't required at the time.]]
* DomesticAbuse: Figures a lot in Irie's backstory. [[spoiler: After his father suffered a traumatic brain injury, he began to act abusive toward Irie's mother. The two ended up hating each other, a fact that Irie regrets]]. This serves as a major motivator for, among other things, [[spoiler:joining work with Takano on Hinamizawa Syndrome]].
* DrivenToSuicide: [[spoiler:In Outbreak, he hopelessly realizes that the parasite spread too fast and is infected himself so he AteHisGun right in-front of Rika Furude.]]
** He's also claimed to have committed suicide near the end of [[spoiler:Tatarigoroshi-hen]], and by extension any arc in which [[spoiler:the Great Hinamizawa Gas Disaster]] occurs. Given the circumstances explained in some of the later arcs, however, [[spoiler:these are at least as likely to be cases of NeverSuicide]].
* HospitalHottie: For a doctor, he's quite young and handsome.
* LargeHam: When he goes into a Keiichi-esque nonsensical rant about Maids in ''Matsuribayashi''. [[spoiler:''[[MoodDissonance In the middle of a life-or-death situation.]]'']]
* {{Meido}}: His fetish.
* ReasonableAuthorityFigure: He always listens to the main characters' worries about what's going on and helps them if possible. Unfortunately, when he figures out what's going on, it's not always to the benefit of the character telling the story...
* WellIntentionedExtremist: [[spoiler:In his past anyway. May have had good intentions but his medical practices were ruthless. See DeadlyDoctor above.]]

[[folder:Mamoru Akasaka]]
!!Mamoru Akasaka
!!!Voiced by: Creator/TakehitoKoyasu (JP - drama CD), Creator/DaisukeOno (JP - anime), Creator/PatrickSeitz (EN)
A young police investigator at the Metropolitan Police Department in Tokyo. He befriended Rika while investigating a case in Hinamizawa four years ago, all due to a prophecy about his wife which came true; he, however, just brushed it off as coincidence.

The fourth arc, Himatsubushi-hen (Time-wasting), is dedicated to him.
* AlliterativeName: If you call him "Akasaka-san".
* BigDamnHeroes: Hoo boy. When he finally reappears, he proves instrumental in taking down the BigBad.
%%* ChekhovsGunman
* EleventhHourRanger: [[spoiler:In the Festival Music Arc.]]
* FairCop:To the point that Rika seems to have a PrecociousCrush on him.
* {{Foil}}: Young, straightlaced, and straightforward to Ooishi's older, perverted, and more wily persona.
* FutureBadass: [[spoiler:In the worlds where his wife dies.]]
* {{Leitmotif}}: [[https://www.youtube.com/watch?v=TtyE3kUIeLY And a pretty cool one.]]
* MeaningfulName: "Mamoru" means "To protect" in Japanese.
* MyGreatestFailure: His inability to solve the Hinamizawa murders [[spoiler: and the eventual disaster that almost inevitably befalls the village]] and consequently his failure to prevent [[spoiler:Rika's]] death serves as this for Akasaka in most of the endings.
%%* RedemptionQuest
* TookALevelInBadass: In ''Himatsubushi'', he's just a greenhorn. In ''Matsuribayashi'', he is refered multiple times as a monster.
** And learned the [[VideoGame/SuperSmashBros Falcon Punch]] during the Level Grinding. [[spoiler:He punches a bulletproof windshield, causing it to shatter.]]
** In the VN, [[spoiler:he doesn't only shatter the winshield, he ''destroys the entire van'' with his punch!]]

[[folder:Oryou Sonozaki]]
!!Oryou Sonozaki
!!!Voiced by: Shizuka Okohira (JP), Creator/BarbaraGoodson (EN)
Mion and Shion's grandmother and head of the Sonozaki household. She appears to be a very harsh old woman and is considered the most powerful person in Hinamizawa. Shion call her "Oni-baba" ("demon granny").

Shion suspects that she was the mastermind in Satoshi's disappearance.
* AbusiveParents: Treats Shion like garbage. [[SarcasmMode Best grandmom ever!]]
* ColdBloodedTorture: The "distinguishment" scene.
* CovertPervert: According to the preview for Kai episode 18, she's an active dominatrix.
* DisproportionateRetribution: Motive for the "distinguishment" scene.
* EvilMatriarch: Her granddaughters call her ''demon granny'', what more do you need to know? Hey! She even has the voice of [[MightyMorphinPowerRangers Rita Repulza]] so why not?
** [[spoiler: In reality, she's not actually evil, just a {{Jerkass}}.]]
* {{Fingore}}: [[spoiler: Again, standard punishment among the Sonozakis. First she had that done when young, then she forced Akane to do it when she didn't like her choice in men, and ultimately makes Shion go through it. (And as a bonus, Mion does it on her own.)]]
* MeaningfulName: "Oryou" contains the character "oni", as do all the names of the Sonozaki heirs. Oryou's daughter Akane (Mion and Shion's mother) used to have an "oni" in her name, but was forced to change the spelling when she was disinherited for marrying an outsider.
%%* NeverMessWithGranny
* PetTheDog: When she gives her support to Keiichi in ''Minagoroshi-hen'', and later in ''Matsuribayashi-hen'' when it is revealed that she was pulling the strings on [[spoiler: Keiichi, of all people -- she put real estate up for sale for the explicit purpose of having an energetic outsider kid like him move in and clear up the village resentment against the Hojou family.]]
* PlausibleDeniability: She's carefully indirect with her phrasing at formal family and village meetings, and alert family members carry out her "wishes". Unless she personally gets her hands on something, she knows nothing of the details of operation. She teaches Mion to function this way as head of the family.
* RedHerring: [[spoiler: She is an UnwittingInstigatorOfDoom with a SureLetsGoWithThat policy, and the {{Yakuza}} background is '''not''' helping her case.]]
* SlaveToPR: [[spoiler:She actually does love her daughter and Shion, plus she forgave the Houjou family long ago, but she has to keep up appearances.]]
* SureLetsGoWithThat: [[spoiler:A policy she has in place. If anything mysterious happens and it's credited to the Sonozaki's, she acts like she is responsible without confirming it. Nastily deconstructed as [[RedHerring this causes]] [[UnwittingInstigatorOfDoom a lot of problems.]]]]
* {{Tsundere}}: In public, she's always harsh, but in private she cares a lot about her daughter and granddaughters.
* UnwittingInstigatorOfDoom: [[spoiler: Major offender of this trope; the Sonozaki family's policy of making them look tougher than they really are bites everyone in the ass by causing them to become incredibly suspicious and cause distrust in the OnlySaneMan of the club. Oryou's actions are the primary cause of the Cotton Drifting/Eye Opening chapters. Her SureLetsGoWithThat attitude is a cause for Ooishi being one himself, which causes her to be indirectly responsible for the Spirited By the Demon and Atonement chapter. Her stubborness towards not cleaning up resentment towards the Hojou siblings is a contributing factor in their problems with the HatePlague.]]
* YouGotSpunk: [[spoiler: Has this opinion of Keiichi after he threatens to split her head open if she doesn't give her support to rescuing Satoko from Teppei.]]

!!Minor Characters
[[folder:Rumiko Chie]]
!!Rumiko Chie
!!!Voiced by: Creator/FumikoOrikasa (JP), Sam Carr (EN)
The female teacher of Keiichi's class, who is a parody character of ''VisualNovel/{{Tsukihime}}'''s Ciel-senpai (permission for her usage was given by [[Franchise/{{Nasuverse}} Type-Moon]]). The seiyu for her character in the anime series is the same as the seiyu of Ciel from the Tsukihime anime. Going along with the parody, her favorite food is curry rice, just like Ciel.
* BerserkButton: Don't you dare insult curry in front of her. It won't be pretty. Sometimes she can hear an insult even when she's not in the room!
* {{Expy}}: If the above wasn't enough, in ''Higurashi Daybreak'', many of Rumiko's moves are direct references to some of Ciel's moves from ''Melty Blood''. In the ExpansionPack, one of Rumiko's alternate outfits is Ciel's nun outfit and, if the player uses this costume, she will talk very much like her ''Tsukihime'' counterpart.
** More specifically, she's an Expy of Ciel-Sensei - she even wears the same pendant. Unlike Neko Arc, her status as just Ciel in a teacher's uniform or as a separate character is not quite confirmed. At least one story in Kagetsu Tohya seems to suggest Ciel Sensei is a separate character, which would make Chie an Expy of an Expy.
* HotTeacher: Parodied in Kira with Keiichi "sketching" her as punishment game in the Soul Brother's delusion.
* MyNaymeIs: Her name is oddly spelled "Lumiko Cie" in the French version, most likely to make her PunnyName more obvious.
* PunnyName: Her name in Japanese order is Chie Rumiko. If you combine "Chie" and "Ru", you get "Chieru", which sounds very similar to the Japanese pronuncation of [[VisualNovel/{{Tsukihime}} Ciel]]'s name.
* ReasonableAuthorityFigure: Unfortunately, there's generally little she can do.
* {{Schoolmarm}}: She's the only teacher at the school the main characters attend, which isn't surprising since Hinamizawa is a rural village. Keiichi is impressed that she manages to teach a class full of students from different grades. Higher grade students are also expected to teach to lower grade ones during free study periods, effectively raising the number of teachers.
* TrademarkFavoriteFood: Curry.

[[folder:Teppei Houjou]]
!!Teppei Houjou
!!!Voiced by: Katsuhisa Hoki (JP), Creator/SteveKramer (EN)
Satoko and Satoshi's uncle/foster father. He and his wife were forced to take care of Satoko and Satoshi after the death of their parents, but they abused them. He left Hinamizawa after Tamae's death, and currently lives in Okinomiya. According to Kasai, he is a pimp and uses his lover Rina to swindle men out of their money.
* [[AbusiveParents Abusive Uncle]]: Not only does he treat Satoko like crap and hits her, one of the TIPS flat-out states that if she had been a few years older, he would have had no qualms about abusing her sexually too. It doesn't end well for him.
* AssholeVictim: [[spoiler:In Tatarigoroshi and Tsumihoroboshi. Also in the [=PS2=] Exorcism chapter and Miotsuki-hen.]]
* ChildHater: Taken to truly repulsive levels in Tatagoroshi and Minagoroshi-hen
* EvilUncle: To Satoko and Satoshi. He's not even their real uncle. His older brother was their stepfather.
* HateSink: He clearly was meant as someone who the audience wants to suffer, and does.
* {{Jerkass}}: '''All''' the time. Even in episodes where he isn't doing anything morally reprehensible, he's still an asshole.
* KarmicDeath: [[spoiler: In Tatarigoshi, Exorcism, Tsumihoroboshi, and Miotsuki-hen.]]
* KickTheSonOfABitch: Frequent target of it.
* KnightOfCerebus: His presence always signifies things getting unpleasant. Lampshaded by Rika in the Massacre Chapter: in any world where Satoko's uncle returns to Hinamizawa, Rika feels she might as well give up at trying to fight against any circumstances.
* LoanShark: One of his activities, with the help of Rina.
* OhCrap: That's how most normal people react to [[spoiler:putting the light on and seeing what was a cute teenage girl 2 seconds ago, brandishing an axe ready to cleave your head in two. Or seeing a furious teenage boy charging at you with a baseball bat while screaming like a banshee.]] He doesn't have the time to say it out loud in either scenario though.
* OutlawCouple: With Rina.
* TheyKilledKenny: Dies quite a lot, mostly to his own evil acts biting him in the ass.
* VigilanteExecution: Vigilante action (for NASTY child abuse and badger games) is the common motive in his many deaths throughout the arcs.
* WouldHurtAChild: As long as he has someone to hit, he's not picky about the age. He also [[spoiler:kills Rika]] in an unseen world.

[[folder:Rina Mamiya]]
!!Rina/Ritsuko Mamiya
!!!Voiced by: Creator/KyokoHikami (JP - drama CD), Creator/MisaWatanabe (JP - anime), Jean Smart (EN)
A woman who appears in Rena's life in ''Tsumihoroboshi-hen''. She is the lover of Teppei Houjou, and together they swindle men out of their money through intimidation and blackmail schemes.
* AssholeVictim: [[spoiler: In ''Tsumihoroboshi''.]]
%%* BareYourMidriff
* BitchInSheepsClothing: She's even worse in the manga compared to the anime. In the anime we know right away she hates Rena. In the manga, Rina confronts Rena about the fact that she doesn't like her, and Rina puts on a pretty convincing act about how she genuinely loves Rena's father. Rena falls for it and starts to reconsider her view on Rina before she overheard her and Teppei badmouthing her father.
* BlatantLies: "I'm pregnant. And since I'm a Christian, I can't have an abortion."
* CruelAndUnusualDeath: [[spoiler:In ''Tsumihoroboshi'', Rena cuts her stomach open and beats her to death with a pipe]].
* DistinguishingMark: A red star-shaped tattoo on her left thigh. [[spoiler: Useful for identifying her mangled, rotted corpse.]]
* {{Foreshadowing}}: In case you don't spot her right from the beginning, the first TIP of ''Tsumihoroboshi'' after she appears tells us her name and her work: the same as Teppei's mistress who was killed horribly three arcs earlier. Woops. [[spoiler:In other words if she dies early, Teppei Houjou returns to Hinamizawa.]]
%%* GoldDigger
* HoneyTrap: [[spoiler: It ends ''badly'' for her]]

* TheSchlubPubSeductionDeduction: It has struck again. Poor Rena's dad.
%%* TattooedCrook
%%* TheyKilledKenny:
* TooDumbToLive: [[spoiler: In ''Tsumihoroboshi''. Rina is lured by Rena to an abandoned Junkyard where no one can hear her scream.

%%* ActionMom
* CurtainsMatchTheWindow: Green hair and eyes, which her daughters got from her.
* {{Fingore}}: Akane was in the receiving end of it due to her feud with Oryou over marrying a guy the clan didn't approve.
%%* KatanasAreJustBetter
* MissingMom: She's rarely on screen due to her estrangement.
* OddFriendship: With [[spoiler:Ooishi]] in ''Matsuribayashi''.
* OddNameOut: She's the only female of her family not to have the character for oni in her name. She used to, but had to change the spelling of her name when she was disowned.
* RedBaron: The "Demon Princess of Shishibone".
* ShipperOnDeck: She really wouldn't mind having Keiichi as a son-in-law with either daughter (preferably Mion) as stated in the Massacre chapter.
* WeaponOfChoice: A katana. Mion must have got it from somewhere.
* {{Yakuza}}: Her husband is a crime boss.

The head of one of the Three Families and the official village chief of Hinamizawa. He seems to be a kindly old man, but is vehement in his hatred for Hinamizawa's enemies.

!!!Voiced by: Kazumi Tanaka (JP)

A scientist who devoted his entire life to researching a disease he calls Hinamizawa Syndrome, which he thinks could shake the entire scientific knowledge about the human brain. However, his research is shunned and mocked by the academic world.


* AGodAmI: A rare case where it's not a megalomaniac rant. He just thinks that if his research is acknowleged, he will become some kind of eternal being, just like a god. The problem is, his beloved granddaughter [[GoneHorriblyWrong took it a bit too seriously.]] His final letter to her really didn't help though (see UnwittingInstigatorOfDoom below).
* AlphabeticalThemeNaming: His first name is written 一二三 (one two three). [[spoiler:Then Miyoko became Miyo (三四 three four).]]
* DrivenToSuicide: When he realized he was [[SanitySlippage going senile]] in his late years.
* JustInTime: Had he come to the orphanage only a day later, [[spoiler:Miyoko would probably have died with her head in that latrin.]]
* ParentalSubstitute: To Miyoko.
* PosthumousCharacter: Died several years before the start of the story.
* UnwittingInstigatorOfDoom: You don't understand the first time (because it seems irrelevant in that arc), but [[spoiler:the first TIP of ''Minagoroshi'' is his [[DeadManWriting suicide letter]] to Miyoko. He tells her that he coudn't become a god and that she must become one in his stead.]] Worst. Will. Ever.

!!Other Characters
!!!Creator/RieTanaka (JP )

A woman from the organization 'Tokyo' who serves as Takano's contact outside of Hinamizawa. Unfortunately, there's far more to her than that...
* BitchInSheepsClothing: [[spoiler:While she does aid Takano in her designs, she ultimately doesn't give a rip about her - and considering half of her plan was to get rid of Tokyo's Koizumi faction whom Takano works for, she likely planned to backstab her anyway.]]
* DissonantSerenity: Every time she speaks, regardless of what kind of carnage of murder is going to happen or ''is'' happening on the other end of the phone line, it's done with the same eerily calm tone. Makes you wonder if this isn't the first time she's done this...
* EvilerThanThou: [[spoiler:Takano is very much her UnwittingPawn, using her anger against Hinamizawa and leaving her to her downfall [[YouHaveOutlivedYourUsefulness once she fails]].]]
* {{Expy}}: To [[Manga/RozenMaiden Suigintou]]. They even share the same actress.
* GreaterScopeVillain:[[spoiler: While the plan and reasons to ruin Hinamizawa are all Takano's, it's Nomura that drove her to do it.]]
** [[spoiler:The first episode of AlternateUniverse ''Outbreak'' OVA unsubtly spells out that she's the chief antagonist. In a meeting with the Prime Minister, she all but admits that her "Alphabet Council" is responsible for the (accidental) titular outbreak of the MindVirus that is steadily spreading across the globe. Oh, and that they were conducting secret tests of the virus and ''planning to turn it into a bioweapon'' long before the outbreak happened.]]
* HiddenAgendaVillain: [[spoiler:All we know about her goals is that she wanted the Hinamizawa Syndrome for ''something'' and that Old Koizumi was in the way. Aside from the non-canon ''Outbreak'' story that details her wanting to use it as a bioweapon, her ultimate plans are forever a mystery.]]
* IHaveManyNames: She uses a different alias for each of her contacts, such as "Maizawa", "Watanabe" and "Takagi". Even Nomura might be a forgery.
* KarmaHoudini: [[spoiler:Lampshaded in the author's notes at the end of the game, saying you have to draw the line somewhere on where the story ends. Thus, she is never held responsible for her actions and in the vast majority of timelines succeeds entirely.]]
** Subverted in Miotsukushi-hen [[spoiler:as she mentioned to be arrested (offscreen).]]
* KnowWhenToFoldEm: [[spoiler:When Okonogi informs Nomura of the current state of things in ''Matsuribayashi'' - that is, that things are currently being FUBAR'd - she orders Okonogi to LeaveBehindAPistol for Takano before cutting all ties with them.]]
* LastEpisodeNewCharacter: Appears only at the end of ''Matsuribayashi'''s [[ProlongedPrologue prologue]], and she doesn't even have a sprite in the original sound novels.
* ManipulativeBitch: She convinces [[spoiler:Takano]] by taking advantage of her emotional state, and probably not only her.
* MysteriousBacker: [[spoiler:A villainous example; she fills in for Old Koizumi after he passes away, serving as Takano's ([[TreacherousAdvisor treacherous]]) advisor.]]
* NothingIsScarier: Outside of her plans for Hinamizawa and being a ManipulativeBitch, ''nothing'' is known about Nomura. And that's probably for the better, because given her actions in [[spoiler:the ''Outbreak'' OVA AlternateUniverse]], whatever she was planning to do in the actual ''Higurashi'' canon is perhaps [[YouDoNOTWantToKnow best left to the imagination]]...
* TheReasonYouSuckSpeech: Gives this out in Ayakashisenshi-hen after learning of Takano's failure to defeat Rika and Satoko and take over Hinamizawa.
-->''"Takano Miyo, you talked a big game, but you were a foolish girl. The duty of the generals was too heavy for you."''
* TreacherousAdvisor: [[spoiler:Nomura is clearly only working with Takano until she can ruin the Alphabet Project and make off with the Hinamizawa Syndrome - which would ultimately ruin Takano in turn.]]
* WalkingSpoiler: As the one who leads [[spoiler:Takano]] down the path to being the BigBad, she is this by itself.
* [[ManBehindTheMan The Woman Behind the Woman]]: [[spoiler:To Miyo Takano. A seldom seen female-to-female version of the trope.]]

[[folder:Tetsurō Okonogi]]
!!Tetsurō Okonogi
!!!Creator/JurotaKosugi (JP - drama CD, anime), Creator/KenNarita (JP - games)
[[MemeticMutation Beware the Gardeners, for they are Anonymous, and they are Legion!]] ... They are actually called the Yamainu ("Jackals"), but they look more like janitors than anything else. Headed by Okonogi, they serve as TheMenInBlack for the majority of the arcs.
* AnimalThemeNaming: Despite being called the Jackals, titles within the organization are bird-themed.
* BloodKnight: He's eager to put his combat skill into use.
* TheDragon: To [[spoiler:Takano]].
* EvilerThanThou: [[spoiler: Okonogi reveals to Takano that she was just being used by Tokyo, then tells her [[YouHaveOutlivedYourUsefulness to commit suicide.]]]]
%%* GovernmentConspiracy
* InformedAbility: [[spoiler:Okonogi loses to a teen girl in hand to hand combat. Losing to Akasaka can be forgiven, but Mion is stretching it. He's also completely outmaneuvered tactically throughout the chapter.]]
** [[spoiler:It's stated the Yamainu are actually a surveillance organization above everything else. So there's adequate reason to suspect their supposed "prowess" in other areas (combat, tactics, etc.) is mostly bluster.]]
* KarmaHoudini: If we assume that he and ''Umineko'''s Okonogi are the same person, that would mean he received little to no punishment after the story. However, that would also mean that he may have [[HeelFaceTurn turned over a new leaf]], as he's ([[MindScrew in the true path, at least]]) shown to be on Ange's side.
%%* TheMenInBlack
* TheWorfEffect: [[spoiler:They consistently fail in ''Matsuribayashi.'' By the end, the entire unit has lost to a bunch of children and Okonogi himself has lost to Mion in a curbstomp battle despite supposedly being an expert in hand to hand combat.]]
** To be fair though, he wasn't exactly in his best shape [[spoiler:since he and his men were already exhausted after walking in the mountains for hours.]]
* WorthyOpponent: [[spoiler:He considers Mion to be this.]]
* YouHaveOutlivedYourUsefulness: [[spoiler: Okonogi gives Takano this treatment when he realizes things aren't going their way. Presumably she doesn't fare any better on other sequences. Strangely enough, this surprises her despite the fact that she knew it would happen ''even if she won.'']]

The guardian god of Hinamizawa, a demonic god of torture and bloodshed. The old legends say that Onigafuchi used to be inhabited by demons, until a sacrifice by Oyashiro turned them human, and that the inhabitants of Hinamizawa are descendants of those demons. Oyashiro-sama is honored by a "Cotton-Drifting Festival", which has dark roots in cannibalism and human sacrifice. Five years ago, when a dam endangered Hinamizawa, the residents prayed to Oyashiro-sama for protection. The dam was cancelled, but ever since, on the day of the Cotton-Drifting Festival, one person has died and another has disappeared, all people who supported the dam. This is the Curse of Oyashiro.
* BigBad: Pretty much everyone points to him as the cause of the mysterious murders in Hinamizawa. He turns out to be [[spoiler:[[DiscOneFinalBoss not responsible]]. And [[SamusIsAGirl not a guy]].]]
* CorruptChurch: [[spoiler:The practice is the problem, not the deity.]]
* DeityOfHumanOrigin: [[spoiler:Was originally human, as revealed in Hanyu's backstory.]]
* [[spoiler:DiscOneFinalBoss: Turns out Miyo Takano was just pretending to be Oyashiro-sama]].
* EldritchAbomination: A black, shadowy deity with the power to make people dissapear and go crazy. Sounds like your typical [[Creator/HPLovecraft Lovecraft]] villain. [[spoiler:[[GoodAllAlong She’s not.]]]]
* GodIsEvil: [[spoiler:Subverted with the true nature of Oyashiro-sama.]]
* HiddenVillain: One of the big mysteries is who or what exactly he is. TheReveal is... complicated.
* MeaningfulName: "Oyashiro" can be literally translated as "the deity is the shrine itself" or "the deity of every eight generations", depending on the characters used to spell it. Normally, it's just written in katakana, though.
* ObviouslyEvil: The few times Oyashiro appears before his true identity is revealed, it’s as a sinister black shadow with glowing eyes (as seen above). [[spoiler:[[SubvertedTrope When she does show up]], [[DarkIsNotEvil well...]]]]
* OurGodsAreDifferent: Since ''Higurashi'' is a Japanese work, Oyashiro-sama takes inspiration from the many gods that exist in Shintoism, namely by being a localized god that's only worshiped by those who live in Hinamizawa.
* ReligiousHorror: The worship of Oyashiro-sama is a form of anti-Shinto. [[spoiler:She is not very fond of it.]]
* UltimateEvil: [[spoiler:Subverted heavily by Hanyu's [[SilentScapegoat true nature.]]]]
* ViewerGenderConfusion: Both an InUniverse example and a deliberate trick on the viewers. Oyashiro is used very mysteriously, at least until until TheReveal that [[spoiler: Oyashiro is actually a girl. No one in Hinimizawa barring Rika knew the the god they worshipped was actually a goddess, most likely due to Oyashiro's legend becoming distorted over hundreds of years]]. And it was foreshadowed as early as the 1st novel [[spoiler: with Keiichi deducing that the breath on him was coming from a girl]].

[[folder:Frederica Bernkastel]]
!!Frederica Bernkastel
A mysterious figure in the ''Higurashi'' universe, author of a series of poems ([[http://forums.animesuki.com/showthread.php?t=31811 fan translated version]]) ([[Trivia/HigurashiWhenTheyCry official translation]]) about the series. The most direct information about her comes from "A Message From Frederica Bernkastel", which basically consists of her laughing about the WildMassGuessing that she's Rika Furude or Oyashiro-sama. Frederica has exactly one scene in the anime, after the credits of the final episode, and a few appearances in the manga.

It is unclear whether she and [[VisualNovel/UminekoWhenTheyCry the Witch of Miracles Bernkastel]] are the same entity or not.
* AmbiguouslyEvil: [[spoiler:In an alternate ending, Frederica prevents the death of Miyo's parents at the end of Matsuribayashi-hen, giving her a happy ending as well. Which means she won't end up screwing up everyone's life in the future, except for the fact that the village is doomed if Miyo never comes. And this may well have been her intent. That act is possibly responsible for the "Dice Killing" chapter of Rei. If she and ''Umineko'''s Bernkastel aren't the same, then she [[UnwittingInstigatorOfDoom is indirectly responsible for the "birth" of "Trollkastel" and all the havoc that ensues.]]]]
* BreakingTheFourthWall: In the games, Frederica will directly address the player, a habit she/her {{Expy}} carries over to ''Umineko''.
* DemotedToExtra: The anime only includes one appearance by Frederica, and none of her poems. Rika also mentions her in Rei.
%%* HimeCut
* LiteralSplitPersonality: [[spoiler:One of the prevailing theories about Frederica's creation is that she was a culmination of hopeless Rikas that were somehow separated from her consciousness after ''Tsumihoroboshi-hen'', wherein Rika gave up on fighting fate after Keiichi's valiant efforts [[HopeSpot still didn't end the time loops]]. Like ''Umineko'''s Bernkastel was born of [[EnemyWithout Rika's death and torment being purged from her soul]], Higurashi's Frederica may have been born by Rika crossing the DespairEventHorizon. [[HilariousInHindsight Which means the mistaken theories of her being an adult Rika might have been more true than previously thought.]]]]
* MeaningfulName: "Frederica" is more or less "Furude Rika" in katakana with a minor change, and Rika drinks Bernkastel wine. They also strongly resemble each other. Nevertheless, Frederica insists, "Frederica and Rika Furude aren't the same. Shame on you if you thought so."
** It doesn't help that in the ''Minagoroshi'' sound novel, she talks about [[MindScrew "us, Rika Furude"]].
** MeaningfulRename: In ''Saikoroshi-hen'', Rika muses that [[spoiler: she's really a separate person from the Rika Furude of ''Saikoroshi-hen'''s world - and by extension, the Rika Furude who existed before the time loops. Rika decides that if she's not truly Rika she should call herself something else. [[LineOfSightName She then looks at a bottle of Bernkastel wine...]]]]
* ReallySevenHundredYearsOld: Actually, like Rika, she's quit counting her age.

[[folder:Natsumi Kimiyoshi]]
!!Natsumi Kimiyoshi
!!!Voiced by: Creator/KaoriMizuhashi (JP)
A girl whose family used to live in Hinamizawa. After the Great Hinamizawa Disaster, her grandmother starts acting strange, setting off a horrific chain of murders.
* AccidentalMurder: [[spoiler:The initial killing of her grandmother was actually an accident on Natsumi's part when she shoved her grandmother away and she hit her head on the table. The subsequent chopping the corpse into pieces was... less of an accident]].
* BloodSplatteredInnocents: Happens to Natsumi ''three times''. [[spoiler:Subverted, because her bloodiness is eventually used to prove that she's not so innocent after all]].
* ChastityCouple: Kinda. It's actually kind of a mix of this and CitizenshipMarriage in Onisarashi-hen's epilogue. Though Natsumi and Akira did start a relationship [[spoiler:before Natsumi's murder spree]], Akira confirms in the epilogue that he can't really say he loves her anymore. At the same time, though, he's certainly devoted to the extent that very few other people would be. [[spoiler:He tries for five years to track her down, forcibly separates her from the abusive circumstances she ended up in, and then marries her to separate her from the baggage and legacy of the Kimiyoshi surname. He attempts briefly to live with her, but finds that she's too emotionally broken for that, so he provides for her to go to a mental institution where she can further recover]]. Oh yeah, and he also takes the blame for [[spoiler:Natsumi's murder spree]] to try and keep that guilt away from her. Not that she buys it. If that's not love and devotion, it's difficult to say what is.
* ContinuityCameo: In the original ([=PS2=]) Miotsukushi-hen, she pops up briefly as a nod to people who had read Onisarashi-hen. Her role is expanded in the subsequent (DS and [=PS3=]) releases of that arc.
* CountryMouse: Okinomiya is a bigger town than Hinamizawa, but this sort of dynamic still plays pretty strongly when she moves to the city.
* DrivenToSuicide: [[spoiler:Someutsushi-hen only.]]
* ExpositoryHairstyleChange: Miotsukushi-hen in the DS rendition. Also somewhat used in the Onisarashi-hen manga.
* GirlishPigtails: Combined with OdangoHair.
* {{Hammerspace}}: In Onisarashi-hen, after she's taken to the hospital after [[spoiler:the murder of her entire family]], she talks with Akira, Chisato, and Tamako in her hospital bed. Chisato and Tamako take her up to the roof where they do her hair. Akira later comes up and has a very difficult conversation with her, in the middle of which [[spoiler:she stabs him with a knife that somehow shows up in her hand]]. Unless the hospital's in the habit of leaving [[spoiler:knives]] around near the hospital beds, {{Hammerspace}} is the only explanation.
* ICantBelieveAGuyLikeYouWouldNoticeMe: Before Akira admits he likes her too, her apparently UnrequitedLove was largely full of this dynamic.
* IAmAMonster: [[spoiler:At the end of Someutsushi-hen]]. Ends about as well as [[spoiler:Shion's]].
* LoveMakesYouCrazy: [[spoiler:Her entire episode of Hinamizawa Syndrome is triggered when she freaks out about Akira seeing paper cut-outs in front of her house intended to ward off evil]].
* MadwomanInTheAttic: [[spoiler:For five years as explained in Onisarashi-hen's epilogue, before Akira moves her to a proper mental institution where she's able to recover more fully]].
* MurderSuicide / SuicidePact: She tries to [[spoiler:force Akira into a joint suicide]] in Someutsushi-hen. It doesn't go exactly to plan.
* MyGodWhatHaveIDone: "Help me... Toudou... he... [[ItsAllMyFault It was my fault...]]!"
* NeverMyFault: She actually spends [[spoiler:her last words]] in Someutsushi-hen [[spoiler:blaming Akira]], presumably for [[spoiler:her own death]], although possibly referring to [[spoiler:her entire episode of Hinamizawa Syndrome]].
* NewTransferStudent: Leads to a lot of her angst, as she isn't terribly settled in the city, and after the [[spoiler:Hinamizawa Gas Disaster]] occurs, one of her big driving motivations is to prevent others from thinking of her and her family as one of those weird Hinamizawans.
* OdangoHair: Two big buns that the author added to make her look a little less plain than the first designs for her.
* TheOphelia: In Onisarashi-hen's epilogue. She never gets over the guilt from [[spoiler:having killed her parents and attempting to kill Akira. After a failed attempt at living with some other relatives who consider her cursed and a failed attempt at living with Akira, she winds up institutionalized, although Akira comes to visit her regularly]].
* RapunzelHair: The odango should be a clue, but you actually get to see her hair loose in the DS version of Miotsukushi-hen, and it is very long.
* RoomFullOfCrazy: The room with all of the seals [[spoiler:that she's locked into by her relatives during the epilogue, in order to protect to relatives from "Oyashiro-sama's curse"]]
* SavvyGuyEnergeticGirl: Appears to become the Energetic Girl to Akira's Savvy Guy in Onisarashi-hen's epilogue. Although once you scratch beneath the surface, the relationship's a bit more complicated than that.
* SelfMadeOrphan: [[spoiler:To repeat, she murders her entire family]].
* ShoutOut: In the PSP game Higurashi Day Break, her charge move looks alot like what Sekai does to Makoto in the finale of the VisualNovel/SchoolDays anime.
%%* ShrinkingViolet
* SympatheticMurderer: [[spoiler:Thanks to FakeMemories and TraumaInducedAmnesia]], her killing [[spoiler:her mom]] looks like this. [[spoiler:The reality is a little different]].
* TearsOfBlood: [[spoiler:In Someutsushi-hen, once she begins [[ClawingAtOwnThroat Clawing At Her Own Throat]]]].
* TemptingFate: When Akira tells her he wants to learn more about her, she says among other things that her favorite movies are those with happy endings. Yeah, Natsumi, that's gonna work out real great for you in the [[KillEmAll When They Cry series]]. [[spoiler:She actually manages to pull off a happy ending in some of her arcs, but most of them are [[BittersweetEnding Bittersweet]] or [[DownerEnding Downers]]]]. In fact, [[spoiler:only in Miotsukushi-hen that she managed to do so.]]
* TraumaCongaLine: In the manga too, but it's definitely stepped up in the DS version. The gas disaster and her entire family's murders happen in all versions, but Someutsushi-hen tosses in all sorts of college related trauma - she finds out that even though all of her friends are shooting to go to one university, she's being cut off due to weaker grades - and the murder of her boss at a retirement center where she works part-time that was done by a Hinamizawan guy she had just befriended a few days earlier. Of course, [[spoiler:She was the one who murdered her family]]. Also, her [[spoiler:attempted murder of Akira, though at that point, she was already pretty well off the deep end]].
* TraumaInducedAmnesia: [[spoiler:complete with FakeMemories]]
* UnreliableNarrator: Half of Onisarashi-hen - and by extension Someutsushi-hen - is simply [[spoiler:FakeMemories she created to repress her own guilt for having been the one to murder her family]].
* VillainProtagonist: [[spoiler:She murders her whole family and tries to stab Akira as well]].

[[folder:Akira Toudou]]
!!Akira Toudou
!!!Voiced by: Creator/SatoshiHino (JP)
A classmate of Natsumi's who she has has a crush on. He admits to liking her back fairly early on and is quickly drawn into the madness surrounding the Kimiyoshi household.
* TheCaretaker: [[spoiler:To Natsumi in Onisarashi-hen's epilogue.]]
* ChastityCouple: Kinda. It's actually kind of a mix of this and CitizenshipMarriage in Onisarashi-hen's epilogue. Though Natsumi and Akira did start a relationship [[spoiler:before Natsumi's murder spree]], Akira confirms in the epilogue that he can't really say he loves her anymore. At the same time, though, he's certainly devoted to the extent that very few other people would be. [[spoiler:He tries for five years to track her down, forcibly separates her from the abusive circumstances she ended up in, and then marries her to separate her from the baggage and legacy of the Kimiyoshi surname. He attempts briefly to live with her, but finds that she's too emotionally broken for that, so he provides for her to go to a mental institution where she can further recover]]. Oh yeah, and he also takes the blame for [[spoiler:Natsumi's murder spree]] to try and keep that guilt away from her. Not that she buys it. If that's not love and devotion, it's difficult to say what is.
* CoolDownHug: [[spoiler:To Natsumi. Subverted.]]
* DespairEventHorizon: [[spoiler:At the end of]] Someutsushi-hen, he looks like he's probably crossed it. [[spoiler:His final words in the arc are him telling Natsumi's corpse that it's OK because everything that had just happened was just a dream. The narration then goes on to say that he would prefer to just fall asleep like that with Natsumi and escape the dream]].
* FailureToSaveMurder: Akira seems to consider himself to have done this to [[spoiler:Natsumi]] at the end of Someutsushi-hen because when she went crazy, he couldn't bring himself to accept her and before things got out of hand, he tried not to talk with her about what might be bothering her. [[ItsAllMyFault How fair this assessment is isn't directly addressed.]]
* LoveMartyr: [[spoiler:Even after she tries to kill him, he's still either pledging his love to her or crying over her dead body right until the end]].
* LoveRedeems: His last-minute usage of ThePowerOfLove [[spoiler:saved both him and Natsumi]] in [[AlternateUniverse one version only]].
* OneSteveLimit: Averted - he shares a name with the main character in Yoigoshi-hen. Of course, it's assured that the two of them will never interact, since the arcs have a 20-year long distance between them.
* TheQuietOne: He's for the most part a pretty darn quiet character who mostly expresses himself through his artwork. His expressions are also a heck of a lot blander than most of the other characters. Of course, once the horror kicks in, he's NotSoStoic [[DespairEventHorizon anymore]].
* SavvyGuyEnergeticGirl: Appears to become the Savvy Guy to Natsumi's Energetic Girl in Onisarashi-hen's epilogue. Although once you scratch beneath the surface, the relationship's a bit more complicated than that.

!!!Voiced by: Creator/EriKitamura (JP - Chisato, ''Kizuna''), Creator/RinaSato (JP - Chisato, ''Sui'') Creator/YukariFukui (JP - Tamako)
Two of Natsumi's friends. Both of them first appeared in the Onisarashi-hen manga and were given expanded roles (especially Chisato) in the DS remakes of that arc, Someutsushi-hen and Kageboshi-hen.
* BrainyBrunette: Tamako. Really, her hair's purplish, but Natsumi (although her hair's greenish-blonde) actually fits [[ShyBlueHairedGirl that trope]] better, and Tamako overall fits this one better, especially since [[HairColorDissonance the purple's pretty darn close to black]].
* BlushSticker: One of Chisato's standard expressions in the DS.

* DeadpanSnarker: Tamako.
* FieryRedhead: Chisato

* RomanticTwoGirlFriendship: Chisato has a bunch of jokes toward this with Natsumi
* ThoseTwoGuys: Particularly in Onisarashi-hen, they're hardly ever seen without each other.

* RedEyesTakeWarning: [[spoiler: First sign of her true colors.]]
