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, where he was the perpetrator of a series of crimes involving shooting young girls with his model gun. His charisma and remarkable talent for speechmaking allow him to easily make new friends and become popular in the village.Early in the story, in Onikakushi-hen and Tatarigoroshi-hen, he is the one affected by the paranoia and driven to commit murder; however, the inner strength and unshaking belief in his friends he acquires in the other arcs are one of the keys to solving the mystery. Eventually, he is even able to recall some of the events of the past repetitions, which helps inspire Rika to defeat fate.The first arc, Onikakushi-hen (Spirited Away by the Demon chapter), is focused on him.
Adaptation Dye-Job: 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.
Book Dumb: 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.
Butt Monkey: 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 tabasco sauce/needle filled ohagi convinced him they were trying to kill him. In fairness if your friends treated you like they do 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 Hanyuu 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 Humiliation Conga 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.
Buxom Is Better: Averted in the manganote Onikakushi, Volume 1, Chapter 3, Page 16. He tells Mion her boobs are too big and that he prefers Rena's more average size. Then again, he may say that both to upset Mion and to make Rena blush.
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.
The Charmer: Called The Magician of Words for his supreme charisma and talent in bullshitting.
Chick Magnet: Though it can also work against him. 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.
Did I Just Say That Out Loud?: 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.
Fanservice: Higurashi no Naku Koro ni Rei, first episode. That's all.
Featureless Protagonist: 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.
Foreshadowing: In the sound novel, Keiichi hears Hanyuu's voice apologizing as soon as just after the title screen of the first chapter. Since he has been away from the village for a few day, 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 Fridge Brilliance, 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 how Hanyuu and Rika forgive themselves for failing the "Groundhog Day" Loop so many times, and are thus able to move on to the future.
The Heart: When he's not a Villain Protagonist. Also, his presence is what gives hope to Rika, since according to her he didn't move to Hinamizawa in two unseen timelines and these were "sad and doomed worlds".
Rika and Hanyuu 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.
I Don't Want to Ruin Our Friendship: 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 True Companions that one can trust like family, and he doesn't want to screw that up by causing jealousy between anyone.
Indy Ploy: Along with fast talking, this is a characteristic distinct to Keiichi, and what his club mates admire and rely on him for.
Intelligence Equals Isolation: 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 Book Dumb.
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 The Heart- is entirely opposite to his old one is probably not a coincidence.
The Leader: Type IV - Charismatic. While not the focus of the story - that's Rika, his charisma and force of personality are essential to bringing everyone together as a group. Rika mentions that there have been worlds where Keiichi never moved to Hinamizawa - all of them doomed to failure.
Lethal Chef: Screwing up some basic stuff like Miso soup or rice is a thing. Almost setting fire to your house while cooking vegetables is Homer Simpson level.
Lolicon: In Higurashi no Naku Koro ni Rei, he is revealed to harbor a rather squicky attraction toward Satoko.
And he even got a nosebleed at fantasizing at Rika going to a brothel in one of the TIPS.
Loners Are Freaks: Once, he got bored of studying and 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.
Love Epiphany: 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 Et Tu, Brute? and Was It All a Lie?.
My God, What Have I Done?: The first is that he realized what horrible things he had been doing back in his old life 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.
Naïve Newcomer: 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.
One Dialogue, Two Conversations: In Onikakushi, a few days after he ate the Ohagi with 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.
The One Guy: 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.'
Red Oni, Blue Oni: 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.
Rousing Speech: An expert on these. Mion goes so far as to call him a master of words. Becomes a plot point in Minagoroshi-hen.
Smarter Than You Look: He's actually among the most intelligent people in the main cast. Shion in particular doesn't think much of his brains.
Supporting Protagonist: The story is really about Rika. However, he is the character that inspires her the most.
Suspiciously Similar Substitute: In-universe, it's a plot point that he bears a lot of similarities to Satoshi. From a determined, hotblooded demeanor to using his old bat as his primary weapon.
Subverted; it turns out the only similarities between them are the ones others want to perceive...until the syndrome strikes, and they act Out of Character in almost identical ways.
Stupid Sexy Friend: 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.
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.
Is it even possible for her to be covert about it? Even when she doesn't outright articulate it (which is mercifully often, since the only possible association she could be making veers deep into "don't go there" territory,) it's still written unmistakably all over her face.
Cry Laughing: In Tsumihoroboshi-hen, she spends a long monologue insisting that she had no other choice than killing 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 loud… before bursting into tears, as she understands fully well that this may not have been the right choice.
The Cuckoolander Was Right: In Tsumihoroboshi, she may not be all there but there are a few things that she actually gets right. 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.
Cute and Psycho: She supplies the Page Image. Though in truth it is a subversion. It's not actually in her normal personality to snap like that.
Cute Bruiser: Able to snap the rope that has her tied up with ease. Can wield the billhook without any difficultly also. And probably brought home the statue of Col. Sandersnote the KFC mascot that's bigger than she is without any assistance.
When Hilarity Ensues 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 he was right.
Daddy's Girl: 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 extreme lengths to protect him. If only he were worthy of such loyalty...
Dark and Troubled Past: She discovered that her mother cheated on her father. While her parents were finalizing their divorce, she 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.
Verbal Tic: 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.
Weapon of Choice: A billhook. Though some confuse it for a machete or cleaver, hence the nickname "Cleaver Girl."
Well-Intentioned Extremist: Tsumihoroboshi-hen. 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, it's just that she thinks that Murder Is the Best Solution.
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 like a tomboy, 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.She's really the younger twin, who was born with the name "Shion", but was forced to trade identities with her sister when she received the oni tattoo by mistake.The second arc, Watanagashi-hen (Cotton-Drifting chapter), is focused on her.
Berserk Button: Shown in Matsuribayashi-hen, do not bring the resentment against the Houjous into the school. As the "den-mother" for the students, you'll regret it. This Berserk Button is the only one in this series that doesn't result in bloodshed.
Cain and Abel: The Abel versus Shion. 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.
Fingore: 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.
Good Bad Girl: Prevalent in the manga where she does such 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 gadfly self. Note that acting perverted is one of her favorite tactics for messing with people.
Luminescent Blush: Happens every time Keiichi says nice things to her. And it's adorable.
Also, note hug in the Atonement arc.
My Greatest Failure: 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.
Nice Girl: Once you get past her playful competitive side, she's one of the kindest members of the cast. 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 Character Development pre-series (Keiichi also developed, but not fully.) 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
Oblivious Mockery: 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 meetings or has to witness her sister's punishment.
One of the Boys: Mion has trouble not just getting her feelings across to Keiichi but also getting him to acknowledge her actual gender.
Only Sane Woman: She's the only one in the cast without a Dark and Troubled Past, and according to Rika 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.
Plausible Deniability: As per her grandmother's indirect phrasing during family planning meetings. This is a clue that the Motive Rant at the end of Watanagashi-hen wasn't from her.
Polar Opposite Twins: Mion is boyish, openly perverted but secretly shy, generous and calm when not playing games. Shion is much girlier, The Tease instead of perverted and tends towards being selfish and 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 Twin Switch confusion) but then Meakashi reveals they're both gadflies, both very 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.
Red Oni, Blue Oni: Red Oni to Shion's Blue. 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.
Shipper on Deck: She plays this role for Keiichi and Rena during the festival in Onikakushi (especially in the sound novel). Which is quite baffling when we learn her feelings for Keiichi in the following arc.
The Tease: 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 The Gadfly above.
Theme Twin Naming: The "on" in Mion and Shion is the same kanji, 音 (meaning "sound").
Tomboy with a Girly Streak: She's a very boisterous Genki Girl 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. 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 slight type B leanings.
Twin Switch: Frequently with Shion. As children, they switched permanently.
Unreliable Expositor: 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. 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.
Unusually Uninteresting Sight: 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...
Then again, she is a Yakuza Princess and heir apparent of the Sonozaki household.
Waif-Fu: Matsuribayashi reveals that she's excellent in hand to hand combat.
Mion's identical twin sister, who currently resides in Okinomiya. 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.She's really the older twin, who was born with the name "Mion". The sisters were forced to permanently trade identities when the younger twin received the oni tattoo by mistake.The fifth arc, Meakashi-hen (Eye Opening chapter), is focused on her. Legendary for its infamy. You Have Been Warned.
Adapted Out: 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).
The Atoner: After realizing what she did in the Eye Opening Arc, she becomes especially aggressive in protecting Satoko in later arcs.
Attempted Rape: No, she's not the recipient. When she is getting ready to torture Keichii in Meakashi-hen/Watanagashi-hen but decides she might spare his life instead, it's implied this is going to happen. Rena and Oishi show up before she tries anything however.
Note that in the VN version of Meakashi-hen, this was never implied, nor did it ever happen. She already knew she was cornered, and just tasered Keiichi and went off to switch with Mion one last time.
Another possibility is that she was never going to rape Keiichi...but she wanted Mion to think she was. Bear in mind that she's specifically trying to torture Mion during this part of the arc.
Badass: In the manga-only arc Yoigoshi-hen. However, she was being possessed by Mion, making her the true badass despite the staggering disadvantage of being dead.
Because You Were Nice to Me: She falls head-over-heels for Satoshi after he merely pats her head. She wonders herself how that could happen so easily.
Cain and Abel: The Cain versus Mion. Though not as much as you are led to believe, since Mion and Shion genuinely love each other.
The Cameo: She appears in a short-story of Umineko, "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.
The Charmer: When Shion wants to be, she is very charismatic. This is especially clear in the Watangashi chapter, where newcomer Keiichi has none of the locals' fear of her family, and she basically waltzes in and starts fucking with him.
Ignored Epiphany: Her reaction to realizing she just crucified Satoko was, number one: wetting herself. Number two: Saying "Oh, what the hell". In the VN, it's expanded upon: 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.
I Just Want to Be Loved: 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 nakama and has actual friends to support her.
Image Song: "Futari no Birthday" and "Ienai Kotoba", along with Mion.
Imaginary Boyfriend: She thinks the footsteps belong to Satoshi and starts talking and laughing with "him". They actually belong to Hanyū.
It Amused Me: 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.
I Will Wait for You: Although two arcs involve what happens if she forgets. Or even thinks she might be.
Kick the Son of a Bitch: Common reaction to her killing Oryou in the 2nd/5th novels and Teppei in the PS2 exclusive "Exorcism Chapter".
Knight Templar Big Sister: For Satoko after the Meakashi arc concludes and she remembers in future arcs that she was asked to protect her.
Matchmaker Crush: Kira, episode 3. 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…
My God, What Have I Done?: 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.
The Rashomon: Watanagashi-hen was told from Keiichi's point of view, and Shion retells it in Meakashi-hen. 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 "exits the stage" herself in Meakashi.
Red Oni, Blue Oni: Blue Oni to Mion's Red. But her true personality is Red; she acts Blue because it is expected from the "younger twin" role she is forced to play.
The Resenter: Normally suppressed, but she has some resentment for Mion because she can still see the boy she likes.
Spanner in the Works: Her actions in Watanagashi and Meakashi are what saves the village in those two arcs. 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.
Start of Darkness: Subverted with the "distinguishment scene". It is so in arcs where she snaps but not in arcs where she doesn't.
Theme Twin Naming: The "on" in Mion and Shion is the same kanji, 音 (meaning "sound").
Tomboy and Girly Girl: The Girly Girl to Mion's Tomboy. 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.
Twin Switch: Frequently with Mion. As children, they switched permanently.
The Unfavorite: As the younger twin, she is denied any family privilege. Especially painful because 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.
Unreliable Expositor: Like a lot of the cast are at varying points. However, this is specifically referring to almost the entirety of what she says at the end of Watanagashi being bullshit.
Younger than She Looks: Maybe it's her civil outfit, her behaviour and personality or her Rapunzel Hair, 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.
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 though by the time of the series any real hostility towards the Houjous as long since petered out and their pariah status is entirely the product of social inertia, which Keiichi helps to overcome to save Satoko from her uncle, her parents died in an accident caused by Satoko while under the influence of Hinamizawa Syndrome, 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. Satoko suffers from Hinamizawa Syndrome, and receives regular injections at the clinic to keep the symptoms under control. She is unaware of her condition, and believes them to be vitamin shots. 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.
The Chew Toy: 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).
Entendre Failure: Presumably because she's one of the Token moes, 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.
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, but according to Rika that's because she forced herself to be hyper-polite not to be a target of gossip when the Hōjō were ostracized. It didn't really help.
Morality Pet: To different character in different arcs, most notably Irie.
My God, What Have I Done?: You might miss it and you won't understand it at the time, but it happens at the end of Minagoroshi chapter when she realizes that her parents weren't trying to kill her and she didn't need to push them off the cliff.
Trap Master: It's her club title. She can make traps that can catch trained soldiers off guard!
Trauma Conga Line: 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.
The main character of Higurashi no Naku Koro ni Kai. She is a younger classmate in Keiichi's school, and 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 human to retain memories of the "Groundhog Day" Loop, and is mentally anywhere from a hundred to four thousand years old, but hides this and continues to act like a child so as not to alarm her friends. She is the only one who can see Hanyu, whom everyone else thinks is an Imaginary Friend.The seventh arc, Minagoroshi-hen (Massacre chapter), is focused on her.
A-Cup Angst: 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 Skinship Grope of Mion. There is also a manga omake where she is jealous of Hanyū's breasts (Hanyū is adult when in her ghost form in the manga).
Barrier Maiden: Her role as Infection Queen. However, this is subverted when the Fridge Logic of the ending of Meakashi-hen settles in.
Better to Die Than Be Killed: She is captured and tortured to death by Shion in Watanagashi; when she ends up in the same situation in Meakashi, she prefers to skip the torture part and stab herself with a kitchen knife.
Bokukko: Uses "boku" as a first-person pronoun, probably a habit acquired from Hanyu. She uses "watashi" when she is her "real" self.
Cassandra Truth: Rika has long since given up trying to convince people that she knows the future.
Cat Girl: Not quite a straight example, but between her punishments (often involving having to wear cat ears) her Verbal Tic ("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 an actual one. The theme is perpetuated by Bernkastel in Umineko: When They Cry, who has a cat's tail and can turn into a cat.
Driven to Suicide: Almost killes 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 realise that by doing this she would just leave this world's Satoko alone.
Hive Queen: It's noted that the older residents in the city are all incredibly fond of her. 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.
Image Song: "Mugen Kairou", and "S A G A Rinne no Hate ni".
Immortal Immaturity: 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. While she does not act her apparent age (somewhere around nine to eleven) it's clear that she's really still pretty childish.
This could be a case of Fridge Brilliance - due to still being preteen, she cannot achieve complete mental maturity, 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.
Japanese Honorifics: The elders of the village (and, curiously, Shion) call her with the rather unusual honorific "-chama".
Jerkass Façade: In Saikoroshi-hen, 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 their dying would no longer be a 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.
Lack of Empathy: 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? 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.
Possible Fridge Brilliance for those who read Umineko, considering the "splinter personality" that was growing insider her during the chain of events and was purged from her subconscious after surviving, giving birth to Bernkastel.
Lady Drunk: A bit of a disturbing example. Really 700 Years Old or not, she is physically a prepubescent girl. In large part it's a way for her to pick on Hanyu.
Leitmotif: Baby's Walk; also used in some situations where a character ridicules himself without getting what's going on.
Little Miss Snarker: At firt 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.
The Many Deaths of You: Most of the time she is disemboweled following the "gut drifting" ritual. But there are also worlds where 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.
Out of Continues: Unlike other examples of "Groundhog Day" Loop, the period of time she and Hanyu can rewind becomes progressively shorter, meaning that her attempt in Matsuribayashi was probably her last chance.
Really 700 Years Old: She's mentally much older than her physical form due to the time loops though not as much as she thinks: Note that her way of thinking has never really matured.
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. But it is implied that she has done the loop for years on end, and even she is not sure how long is it, but it is possible that it's hundreds of years...
Reincarnation: She's thought to be the reincarnation of Oyashiro-sama.
Supporting Protagonist: Shares the status with Keiichi. 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.
Weapon of Choice: Satoko's Hinamizawa Syndrome medication, and strangely enough, a mop.
With Friends Like These...: 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.
The mysterious "transfer student" in Matsuribayashi-hen. She has a pair of dark-colored horns on her head, one which is chipped slightly. In fact, she has appeared to Rika all her life, but only in Matsuribayashi-hen did she gain the power 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 kimchi, which Rika uses in large amounts when Hanyu is being particularly annoying (Hanyu's and Rika's senses are linked together).Hanyu is the basis of the legend of Oyashiro-sama, but the legend has become distorted over hundreds of years, and she is horrified by the actions carried out in her name. She is the one responsible for the eternally repeating June 1983, which she created in order to save Rika's life. Her appearance isn't her real form, see right pic above.The eight arc, Matsuribayashi-hen (Festival Music chapter), is focused on her.
Absurdly Youthful Mother: In life, she had a husband and a daughter. However, she was already an adult when she died (as you can see by the form to the right), and only appears to be around Rika's age in the present as a way to better relate to her.
Angel Unaware: An inversion. First, Oyashiro is definitely stated to be a god. However, it becomes ambiguous when she defines what appears to be a god in the setting. It turns out that she was originally a human who ascended to godhood by dying for the sins of others.
Bokukko: Uses "boku" as a first-person pronoun, despite having none of the defining traits of the trope. According to her, that's because in her time (she is 1000 year old after all) boys and girls didn't speak differently.
Break the Cutie: Quite a lot, though often missed in the anime adaptation or replaced with a more cute reaction.
Continuity Snarl: At the end of Matsuribayashi-hen (the conclusion of the main storyline) and in the later Yumeutsushi-hen, Hanyuu stays as a physical being... but in the in-between chapter Saikoroshi-hen, she's suddenly a spirit again. This is never explained.
Determined Defeatist: 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.
Freakiness Shame: She has something of a complex about her horns. Rena thinks they're 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 her horns existed when she was originally human, and are a large part of the reason why she was chosen as a sacrifice.
Going Commando: In her Miko outfit. Ironic given that her real form's garb is much more conservative.
Horned Humanoid: It turns out that she used to be a regular human who just so happened to have horns, hinted to be because of a genetic defect. Her horns were largely the reason why she was sacrificed, since many people believed her to be a demon because of them.
Immortal Immaturity: Much moreso in the anime than in the visual novel or the manga. Generally, she can really act and sound like a thousand-year old goddess when she is serious, even calling Takano "human child" at the end of the last arc. She actually seems to have the same kind of dual personality as Rika.
Messianic Archetype: Subverted. Hanyu was one in the past, allowing herself to be killed via Watanagashi 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.
Not-So-Imaginary Friend: She has appeared to Rika all her life and Rika thought she was just her Imaginary Friend. 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.
Only Known by Their Nickname: Most people call her Oyashiro-sama, people who know her call her Hanyu, but her real name is Hainryun Ieasomuru Jieda. She got the nickname of Hanyu because her husband couldn't memorize her full name.
Overly-Long Name: Hainryun Ieasomuru Jieda; to the point that her husband had trouble remembering it and shortened it to her current name, Hanyuu.
Parental Substitute: 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 an Imaginary Friendand do things she never taught her.
Physical God: But only in Matsuribayashi-hen. It appears to be a significant step down on the power scale.
Self-Made Orphan: As part of the deal to allow her people to live in Hinamizawa, she allowed herself to be set up as a scapegoat and killed by her daughter via ritual butchering. As her daughter was also the daughter of one of the village priests, this brought unity to the two factions.
Shipper on Deck: She teases Rika quite a bit when she is when Akasaka comes to her home to occupy the house while she and Satoko are hiding at Mion's place. As a response, Rika eats dinner with Akasaka; a super-spicy dinner.
Spirit Advisor: 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.
Tagalong Kid: Even before the group aside from Rika could see her.
Time Master: Can stop time, though it's 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.
Satoko's older brother, who disappeared a year before the story began. It's eventually revealed that he killed his aunt to protect Satoko, but then succumbed to Hinamizawa Syndrome and was taken to the Irie Clinic's basement, where he remains in a coma.
Big Brother Instinct: 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.
Chekhov's Gunman: 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).
Convenient Coma: 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?"
Ill Boy: According to Dr. Irie, he was frail due to a heart condition.
Image Song: "Yellowsick". Ironically, he has one of the most energetic and hot-blooded image songs of the cast.
Knight Templar Big Brother: He killed his aunt in order to protect Satoko. In large part it was due to Hinamizawa syndrome, though.
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.
Fan Nickname: Mr. Delicious, since his name sounds like "oishii", the Japanese word for "delicious".
Inspector Javert: He's usually right, though, like in Tatarigoroshi-hen and Onisarashi-hen. 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.
Knight of Cerebus: In most arcs, he signals the end of comedy, or a sharper dive into tragedy, not always in his first appearance, but in his first confrontation with the arc's protagonist. Lampshaded by Dr. Irie.
It's Personal: 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. 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.
Mentor Archetype: 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 scolded him in front of everyone. He started to consider that man as a second father.
Obfuscating Stupidity: 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.
Odd Friendship: With Keiichi in Minagoroshi-hen and Akane Sonozaki in Matsuribayashi.
Unwitting Instigator of Doom: 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 Rika to get help from. Particularly egregious in Onikakushi-hen, where he's arguably the cause of Keiichi going off the deep end, but he also exacerbates 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 the one reliably sane person in the group.
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. It turns out later, however, that he is actually murdered by Miyo, who gives him a dosage of Hinamizawa Syndrome that results in him clawing his own throat out.
Badass: Not to the level of Akasaka but he gives the six Mountain Hounds who try to immobilize him a run for their money.
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 she seems to enjoy putting people on edge. 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.It turns out that she is the mastermind of the events taking place in Hinamizawa, and wants to murder Rika and set off Hinamizawa Syndrome in the whole town so she can prove her grandfather's research. Since her will and manipulations are so strong as to affect the people in the village both directly and indirectly, she in fact fakes her death through the first six arcs of the story (the corpse in the barrel being a stolen corpse), and murders Rika in five of the eight arcs.
Specifically, it was influenced by a comment her grandfather offhandedly made, saying that if his research proves fruitful his legacy will live forever, like that of a god. Fast-forward to modern day and Miyo raves about how if she proves her grandfather's research is true, and re-inspires fear of Ooyashiro-sama in the process, she will in effect become Ooyashiro-sama and live forever with her grandpa.
Anti-Villain: An interesting take on a 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 Orphanage of Fear 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.
Attack! Attack! Attack!: Lampshaded in a serious manner. 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.
Deadly Doctor: Although she's always one of the first two victims of Watanagashi, she isn't quite so helpless as you'd think. Especially since she isn't really a victim. Plus, her weapons of choice in Higurashi Daybreak are syringes.
Epileptic Trees: 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!)
Fan Nickname: Droopy-Tan, for her 'droopy' features that make her appear sleepy-eyed.
Freudian Excuse: Grew up in a hellish Orphanage of Fear. Almost immediately after the flashback you are loudly reminded that yes, she's still a sociopathic bitch.
It's an odd example, and possibly even a subversion, as she was rescued from the orphanage while still very young, and raised by a loving, kindly old man. Unfortunately, the trauma she already had from the orphanage led to her taking a few things that that her grandfather said the wrong way, which, combined with 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.
Ironic Echo: Not exactly a quote, but the scene near the end of Matsuribayashi-hen where her bullet misses Hanyu very closely echoes the scene near the beginning of the arc where "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 her bullet missing Hanyuu is a sign that Rika and Hanyuu's determination to live has finally reached the same level as Miyo's will to live on that day.
It didn't miss on purpose. Although the anime does not show this, Hanyuu 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.
Karma Houdini: 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 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 Rika's parents, the first murderer and generally being a sociopathtic researcher.
Naughty Nurse Outfit: Irie once notes that since she is a doctor she isn't supposed to wear a nurse outfit (with an impressive Zettai Ryouiki 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.
Nay-Theist: Highly disparaging of the local religion. She actually hates God despite appearing to be a Christian.
Noblewoman's Laugh: Gets a classic one in the anime after her A God Am I speech, yet it's somehow less disturbing than most the protagonists' laughs.
Not Quite The Right Thing: 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.
Numerical Theme Naming: The kanji for her name uses the kanji for three (三) and four (四). Just like how her adoptive grandfather's name is written as one (一), two (二), three (三).
Nice Hat: Her nurse's cap. Also, her epic special forces beret.
Official Couple: Double Subverted with Tomitake. In the first season, they merely look like an Odd Couple. 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.
Orphanage of Fear: She was sent to one of these after her parents died, witnessing and suffering lots of horrors there. She got so throughly broken that she went INSANE and became the Big Bad with time.
Psychopathic Womanchild: Despite many characters describing her as a mature adult woman, her personality is actually frighteningly childish.
Smite Me, O Mighty Smiter: She challenges God to give her a better life or kill her. A subsequent lightning bolt narrowly misses her.
Softspoken Sadist: 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 BIG shot foreshadowing her Playing with Syringes and other overt sadism.
Troll: She manipulates several characters into going paranoid and berserk out of sheer amusement.
Unwitting Instigator of Doom: 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.
Used to Be a Sweet Kid: 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.
Villainous Breakdown: Started in Matsuribayashi-hen when Rika was falsely reported as dead for 48 hours and it just got worse after she was beaten.
Woman in Black: In Minagoroshi-hen, right before she kills Keiichi and the others one by one until she sacrifices Rika.
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 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. It is later revealed that he works under Miyo, where he is trying to find a cure for Hinamizawa Syndrome while not knowing of his employer's true desires.
Deadly Doctor: He performed psychosurgery on unwilling patients in the past, although he had good intentions. Patient consent wasn't required at the time.
Domestic Abuse: Figures a lot in Irie's backstory. 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, joining work with Takano on Hinamizawa Syndrome.
Driven to Suicide: In Outbreak, he hopelessly realizes that the parasite spread too fast and is infected himself so he Ate His Gun right in-front of Rika Furude.
Reasonable Authority Figure: 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...
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.In an untold world, Mamoru regrets being unable to save his wife and Rika, learns martial arts to clear his mind, and hopes to relive the time before the Time Wasting Chapter to save them. Through a miracle, Mamoru inherits his martial art skills in Matsuribayashi-hen, and decides to save Rika from her destined death as a payment for saving his wife through her prophecy.The fourth arc, Himatsubishi-hen (Time-wasting), is dedicated to him.
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 incorrectly suspects that she was the mastermind in Satoshi's disappearance and accidentally kills her while attempting to interrogate her in Watanagashi-hen and Meakashi-hen.
Evil Matriarch: Her granddaughters call her demon granny, what more do you need to know? Hey! She even has the voice of Rita Repulza so why not?
In reality, she's not actually evil, just a Jerkass.
Fingore: 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.)
Meaningful Name: "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.
Pet the Dog: 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 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.
Plausible Deniability: 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.
Unwitting Instigator of Doom: 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 Only Sane Man of the club. Oryou's actions are the primary cause of the Cotton Drifting/Eye Opening chapters. Her Sure, Let's Go with That 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 Hate Plague.
You Got Spunk: 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.
The female teacher of Keiichi's class, who is a parody character of Tsukihime's Ciel-senpai (permission for her usage was given by 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.
Berserk Button: 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 Expansion Pack, 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.
Red Baron: "Shotgun Tatsu". Do not mess with this guy!
Romantic Runner-Up: According to Shion, her father, Kasai and Akane had a Love Triangle in their youth. Kasai lost but stayed close to Akane as right-hand man. It didn't end so badly for him at all since he does get to watch over Shion.
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.
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.
Asshole Victim: In Tatarigoroshi and Tsumihoroboshi. Also in the PS2 Exorcism chapter.
Loan Shark: One of his activities, with the help of Rina.
Oh Crap: That's how most normal people react to 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. He doesn't have the time to say it out loud though.
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. Her real name is Ritsuko, but she uses Rina as a fake name.In Tsumihoroboshi-hen, Rena kills her bloodily to protect her father. Also, in Tatarigoroshi-hen and Minagoroshi-hen, she is murdered by members of the Yakuza when she tries to flee Okinomiya, prompting Teppei to move back to Hinamizawa. In Miotsuki-hen, she is killed by the Yaminu.
Bitch in Sheep's Clothing: 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.
Blatant Lies: "I'm pregnant. And since I'm a Christian I can't have an abortion."
Distinguishing Mark: A red star-shaped tattoo on her left thigh. 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.
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. As this includes Satoshi and the rest of the Houjou family, he is killed by Shion in Watanagashi-hen and Meakashi-hen. In Minagoroshi it's revealed that he actually has nothing against Satoshi at all but couldn't publicly state it, eventually supporting Keiichi's efforts to protect Satoko.
Meaningful Name: The characters for "Kimiyoshi" can be rearranged to form the character "oni".
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. When Miyoko Tanashi, the daughter of one of his students, calls him for help during her failed attempt to escape her Orphanage of Fear, he comes to pick her up and saves her from certain death. He becomes her grandfather afterwards.
A God Am I: 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 took it a bit too seriously. His final letter to her really didn't help though (see Unwitting Instigator of Doom below).
Unwitting Instigator of Doom: You don't understand the first time (because it seems irrelevant in that arc), but the first TIP of Minagoroshi is his 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.
A woman from the organization 'Tokyo'. She first appears after Koizumi dies in 1981 and confronts Takano Miyo about the future of her research on the Hinamizawa Syndrome.Her true motive is to have the Old Koizumi faction in Tokyo fall down due to the Great Hinamizawa Disaster and the research project becoming a mess afterwards along with wanting to see how far they can decieve people with the syndrome, real or not. She is shown to be a skilled manipulator of emotions, using Takano's grief and acting as though she understands in order to gain her trust and become the new backing up of the research institution.
Badass: Is shown to be this in the dream at the beginning of Ayakashisenshi-hen, seeing just how damn skilled she is at using her telephone cord as a chain to wrap around the arm of a big-breasted, adult version of Magical Girl Oyashiro Rika.
I Have Many Names: She uses a different alias for each of her contacts. We don't know her real name.
Karma Houdini: 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.
Know When to Fold 'Em: When Okonogi informs Nomura of the current state of things in Matsuribayashi - that is, that the Yamainu were getting wrecked by Rika and the kids - she orders Okonogi to Leave Behind a Pistol for Takano before cutting all ties with them and her.
Informed Ability: 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.
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.
The Worf Effect: 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 since he and his men were already exhausted after walking in the mountains for hours.
You Have Outlived Your Usefulness: Okonogi gives Takano this treatment when he realizes things aren't going their way. Presumably she doesn't fair 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. Oyashiro-sama is in fact Hanyuu, Rika's Not-So-Imaginary Friend.
Meaningful Name: "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.
Religious Horror: The worship of Oyashiro-sama is a form of anti-Shinto. She is not very fond of it.
A mysterious figure in the Higurashi universe, author of a series of poems (fan translated version) (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 Wild Mass Guessing 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 the Witch of Miracles Bernkastel are the same entity or not, but they are both born from Rika's endlessly repeating fate.
Meaningful Name: "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 "us, Rika Furude"…
Pet the Dog: 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...
Kick the Dog: ... except for the fact that the village is doomed if Miyo never comes. And this may well have been her intent.
A detective who investigates the curse of Oyashiro and the gas disaster. Initially, she got involved through the case of Rena Ryugu back in 1982. She later on gets deeply involved with Natsumi's problems through her investigations. She is included in only the DS renditions of what was known in the manga as Onisarashi-hen. These became Someutsushi-hen and Kageboushi-hen. She also appears in the DS rendition of Miotsukushi-hen and a DS-only arc called Tokihogoshi-hen.
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 which Natsumi is actually responsible for.
Blood-Splattered Innocents: Happens to Natsumi three times. Subverted, because her bloodiness is eventually used to prove that she's not so innocent after all.
Continuity Cameo: In the original (PS2) Miotsukushi-hen, she pops up briefly as a nod to people who had read Onisarashi-hen.
Country Mouse: Okinomiya is a bigger town than Hinamizawa, but this sort of dynamic still plays pretty strongly when she moves to the city.
The Ophelia: In Onisarashi-hen's epilogue. She never gets over the guilt from 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.
Suicide Pact: She tries to force Akira into one of these in Someutsushi-hen. It doesn't go exactly to plan.
Trauma Conga Line: 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, She was the one who murdered her family. Also, her attempted murder of Akira, though at that point, she was already pretty well off the deep end.
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. Depending on which version, his intervention leads to either a bittersweet ending or a tragic one.
One Steve Limit: 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.
The Quiet One: 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 Not So Stoicanymore.
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. In the latter arc, Chisato is attacked and hospitalized by Natsumi. Later, she meets Natsumi in the hospital. Although the two struggle for a bit, Chisato is able to calm Natsumi down.
One Steve Limit: Averted - he shares a name with Natsumi's love interest in Onisarashi-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.
A woman who decided to visit Hinamizawa with her boyfriend, Takumi, where she meets Otobe. She suggested the trip to him in order to murder him there, having been driven to that point by his abusive nature.
Comforting Comforter: Subverted once you find out that the reason she covered him like that was to make it look like he was sleeping, when he was actually dead.
My God, What Have I Done?: Yae feels no remorse for killing Takumi until Mion proves to her that he intended to get a real job and turn over a new leaf by speaking to him from beyond the grave and finding an employee's notice on his body.
A man who accompanied his girlfriend, Yae, on an outing to Hinamizawa. Early on, it is established that he is rather abusive to his girlfriend. He tried to use the trip as a way to mark having started over by getting a real job and being able to provide a good life for Yae; unfortunately, Yae had not realized this and murdered him in his sleep.
A freelance writer who appears in the DS rendition of Yoigoshi-hen, accompanying Otobe and everyone else. It turns out that she's actually Miyuki Akasaka, Mamoru's daughter as an adult, and is actually an undercover police officer.
A childhood friend of Rena's from Ibaraki and a relative of one of the boys Rena assaulted. She appears in Tokihogushi-hen. She helps with Tomoe's investigation into Rena's case.
