History Characters / HigurashiWhenTheyCryMiscellaneousCharacters

* KickTheSonOfABitch: While a vile manipulator, Nomura abandoning Takano by making her kill herself and take all the blame for the operation isn't completely unjustified, as Miyo herself is quite a terrible person as she was willing to murder children, slaughter an entire village, and has dissected people alive, it's hard to argue she didn't have it coming.

!!!''Higurashi Rei'' Characters
[[folder:Keitarou Maebara]]
!!Keitarou Maebara

Keitarou is the son of Keiichi. They lived in Tokyo due to Keiichi's job as a congressman's secretary and would make yearly visits to Hinamizawa. Keitarou's since moved to the village 3 weeks ago in June 2019 to live with his mother and grandparents, and attends the Okinomiya middle school as a second-year.

* AllLovingHero: Keiichi taught Keitarou that "harmony among people is most important". Keitarou puts it into practice by wanting to befriend everyone.
* CityMouse: Like his father, he moved from Tokyo to the rural town Hinamizawa. Although, Keiichi brought Keitarou to visit Hinamizawa a lot before moving so he considers himself a Hinamizawan at heart.
* {{Determinator}}: When he decides to make friends with someone, nothing can stop him from keep trying.
* TheGadfly: He loves teasing Kihiro by telling playful lies as he knows how much Kihiro hates lies.
* NiceGuy: Keitarou inherited his father's friendly and sociable personality.
* WideEyedIdealist: He seriously believes he can make friends with ''everyone'', even though the people of Polaris are basically a cult that rejects all communication with people outside their circle and almost everyone in Hinamizawa would want them out of the village.

Kihiro is the son of Rena and her ex-husband. Kihiro grew up with Keitarou as his best friend and now attends the Okinomiya middle school with his friends.

Tamaki is the daughter of Mion. Her grandmother Akane is the current head of the Sonozaki family, with Tamaki being the one to become the successor after Mion. Tamaki attends the Okinomiya middle school with her friends.

* BewareTheNiceOnes: She's a sweet and cheerful girl, but she's still a Sonozaki so you can expect her to be scary when she's angry.
* CurtainsMatchTheWindow: Like her mother, Tamaki's hair and eyes are both green.
* GroinAttack: She squeezes Keitarou's balls until she almost crushes them. She then explains Sakiko told her grabbing a man's balls is the fastest way to grab his heart, not realizing she was trolling her.
* HereditaryHairstyle: Being Mion's daughter, she has the same ponytail hairstyle that her mother had at her age.
* HimeCut: She has parted blunt bangs, chin length sidelocks, and long straight hair worn in a ponytail. Her hairstyle reflects her position as the current heiress of the Sonozaki household, one of the Three Great Families of Hinamizawa.

[[folder:Sakiko Kimiyoshi]]
!!Sakiko Kimiyoshi

Sakiko is the daughter of Satoko. Her mother owns a souvenir shop, where Sakiko works at sometimes. She's in her third year of middle school while all her friends are in their second year, being a year older than everyone in the new generation.

!!Characters from Console Releases

[[folder:Tomoe Minai]]
!!Tomoe Minai
!!!Voiced by: Creator/NanaInoue (JP)
[[quoteright:171:https://static.tvtropes.org/pmwiki/pub/images/minai_tomoe.png]]

A detective who investigates the curse of Oyashiro and the gas disaster. 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''.

* AlmostDeadGuy: Right after apparently getting a major break in the Hinamizawa Gas Disaster case in [[spoiler:Kageboushi-hen, Tomoe is stabbed at a gas station but still manages to use her last words and a major case of ProperlyParanoid]] to pass along a bit of the information to the police department.
-->'''Tomoe:''' [[spoiler:Shiro... cabinet office.]]
* BigEater: She can eat many hamburgers and cakes at once all by herself.
* BoyishShortHair: She's a serious detective woman with short hair.
* DespairEventHorizon: Tomoe briefly hit this in her backstory after Madoka ran away. She gets as far as [[DrivenToSuicide contemplating suicide]], but Oishi, of all people, manages to get her back out of it.
* FairCop: She's a very attractive young female detective.
* {{Foil}}: To Ooishi, in a very similar vein to Akasaka. She's a very young, attractive, extraordinarily competent, straight-arrow, female detective. Ooishi is a detective who is obese, on the verge of retiring, often comes off as a slacker to others, cuts corners on the rules anywhere he can, and womanizes like crazy.
* TheGloriousWarOfSisterlyRivalry: The Smart Sister to Madoka's Beautiful Sister. Both sisters work in the Kakiuchi police force, and both repeatedly get into arguments with each other, sometimes over relatively petty stuff (e.g. "borrowing" shampoo from the other without asking), but a lot of it stems from the awkwardness from Madoka being in a relationship with Tomoe's boss.
* InTheBack: [[spoiler:She gets stabbed from behind by a woman at a gas station and dies from her injuries]].
* InspectorJavert: Similar to Ooishi, [[spoiler:and just as similarly proven to in fact be right]] in those situations.
* JerkWithAHeartOfGold: Tomoe may be a typical neurotic mood-swinging lady who can easily lose her temper over some trivial things but she's also a compassionate person who works as a police detective to find culprits to seek justice for those who are the victims.
* ParentalMarriageVeto: Tomoe dislikes Madoka being engaged to Police Chief Yamaoki because he is Tomoe's boss. Since both their parents are dead and Tomoe was made Madoka's guardian, Tomoe's objection plays a similar role to a parent's objection.
* PromotionToParent: She became a guardian to her younger sister Madoka after their father's death, but Madoka ended up running away from home.
* ProperlyParanoid: Correctly sensing that something was amiss before refueling at the gas station in Kageboushi-hen, [[spoiler:she went ahead and mailed a package of some of the documents she'd discovered relevant to the Hinamizawa Gas Disaster case just before she is murdered at the gas station]].
* PursuingParentalPerils: Both she and her sister Madoka work with the police department. Their father was killed in the course of duty as a police officer.
* ReallyDeadMontage: [[spoiler:Gets one after dying from her wounds in Kageboushi-hen]]. Granted, this is ''VisualNovel/WhenTheyCry'', so it's doubtful the audience was expecting her to come back even before the montage, at least until [[spoiler:the next time loop]].
* ShippingTorpedo: She doesn't support her younger sister Madoka's engagement with her boss Yamaoki, as she hates having her boss as a brother-in-law.
* SweetTooth: She has an appetite for desserts and becomes a regular at Angel Mort.
* TabloidMelodrama: After her parents died in the arson on her house, the media speculation about whodunnit ran rampant. At one point, the newspapers started positing that Tomoe had been the original target of the arson and it was done by some students she competed with in sports, since she had managed to achieve a lot athletically. This did not endear her to the other students. Even at the time of the main story, she still has very hard feelings toward the press about that, as well as the rumors they spread about Madoka, who was already struggling psychologically.
* TrademarkFavoriteFood: She loves hamburgers and often eats dozens of them at a time.

[[folder:Kazuma Hatakeyama]]
!!Kazuma Hatakeyama

An old man from Hinamizawa who Natsumi meets during her part-time job at the Care and Welfare Center. Though unsociable at first, he and Natsumi build a friendly relationship around their shared heritage. He is a devout believer in Oyashiro, a tendency that becomes more emphasized after [[spoiler:the gas disaster]].

* AxCrazy: In the Stain-Spreading Arc, [[spoiler:he goes off the deep end after the gas disaster and kills Natsumi's boss before committing suicide]].
* CommonalityConnection: He and Natsumi bond over their shared Hinamizawan heritage.
* DefrostingIceKing: He puts up a front of being unsociable to everyone at the Care and Welfare Center. Really, he's just lonely and misses his hometown. He warms up toward Natsumi as soon as he learns that she is also Hinamizawan.
* DroppedABridgeOnHim: In the Silhouette Arc, [[spoiler:he is killed off camera by]] an acquaintance who succumbed to the curse. This happens before Natsumi can even meet him during her part-time job in that arc, allowing the arc to focus more on some of her core insecurities about Akira and the fallout from the [[spoiler:Great Hinamizawa Gas Disaster]] than the Stain-Spreading Arc could.
* RoomFullOfCrazy: He scrawls prayers to Oyashiro in blood all over the walls of his room at the Care and Welfare Center in the Stain-Spreading Arc.

* ChildhoodFriends: She was friends with Rena during part of their childhood in Ibaraki.

!!!Voiced by: Creator/TomokazuSeki (JP)
[[quoteright:160:https://static.tvtropes.org/pmwiki/pub/images/furude_riku.png]]

Hanyu's husband in her past life.

* AccidentalPervert: His first meeting with Hanyu, as shown in ''Kotohogushi-hen'', had him interrupting Hanyu's bath at a waterfall and getting a look at her naked body when he was being chased by a bear.
* FamilyThemeNaming: His given name, Riku, sounds very similar to Rika, the name of his direct descendant.
* FlorenceNightingaleEffect: After Hanyu saved him from a bear, a tree branch pierced her foot and Riku took her to his home to treat her wound. She ended up liking living there and after a couple of years, they got married.
* ForgottenFirstMeeting: Hanyu rescued Riku while he was still a baby from a house burned by "half-blood" (implied to be those infected by the syndrome) but they do not meet again until he had grown into a young man. Hanyu doesn't realize that Riku is the baby she saved years ago until she meets his father.
* HappilyMarried: He deeply loved Hanyu and their marriage shown in segments of ''Kotohogushi-hen'' was quite happy.
* IWantMyBelovedToBeFashionable: He had an obsession with {{Miko}} uniforms and was constantly trying to get Hanyu to put on his modified shrine maiden outfits.

* RescueRomance: Hanyu first saved his life when he was just a baby and she took him to safety after his mother was killed by "half-blood" demons. Years later, Hanyuu saved him from a bear and he let her live at his home in gratitude, eventually asking her to become his wife.

[[folder:Ouka Furude ('''Unmarked Spoilers''')]]
!!Ouka Furude
!!!Voiced by: Creator/YukariTamura (JP)
[[quoteright:160:https://static.tvtropes.org/pmwiki/pub/images/furude_oka.png]]

Hanyu and Riku's only daughter.

* AscendedExtra: Originally, she was only mentioned in the [=TIPs=] of ''Matsuribayashi-hen''. Her backstory with Hanyu was later expanded with a flashback in the first release of ''Miotsukushi-hen''. Later, the Kizuna installment included an entire chapter dedicated to explaining Hanyu's past with Ouka.
* CherryBlossomGirl: Her name contains the kanji of cherry blossom. Her mother gave her this name because the cherry blossoms were dancing in the wind when Ouka was born.
* ChildhoodFriendRomance: She married Shino Kimiyoshi's son Shouji who she knew her entire life and grew up with her almost like a brother.
* ChronicHeroSyndrome: She asked Hanyu to make her a miracle medicine to save the villagers from an epidemic. Despite Hanyu's warnings about consequences, Ouka continued to save the villagers and eventually a conflict broke out because the feudal lord wanted to threaten Ouka into giving the recipe of the medicine. Ouka's husband and daughter were apparently killed and Hanyu went into a rampage against the villagers, forcing Ouka to kill her own mother.
* EarlyInstallmentCharacterDesignDifference: The Matsuri version of ''Miotsukushi-hen'' includes a flashback that shows Ouka looking exactly like Rika with light purple hair. The Kizuna release that includes ''Kotohogushi-hen'' gives a more differentiated design to her adult self's sprites and also changes her hair color to blue like Rika's.
* FamilyThemeNaming: Both her name and Rika's use a [[FloralThemeNaming type of flower]] for the first character and share the final character "ka."
* HappilyAdopted: After her father died and her mother left the village out of remorse for being forced to kill him, Ouka was raised by Hanyu's close friend Shino Kimiyoshi who loves Ouka as her own daughter until she turned ten years old and moved to the Furude Shrine.
* HimeCut: She has blunt bangs, cheek-length sidelocks, and hip-length straight hair. Like her descendant Rika, Ouka was the daughter of a Shinto Priest of the Furude Shrine where she served as a {{Miko}}.
* HumanDemonHybrid: She's the child of a human man and a demon woman.
* IdealHero: She's portrayed as a heroic woman who did everything in her power to protect Hinamizawa and its villagers. Even after many villagers turned against her, Ouka killed her own mother to protect them.
* InconsistentColoring: Her first sprite has light purple hair in the Matsuri version of ''Miotsukushi-hen''. Her sprite in ''Kotohogushi-hen'' has blue hair like Rika.
* MarkOfTheSupernatural: She inherited the purple eyes of her mother, a symbol of her demon heritage.
* MasterSwordswoman: She was skilled in swordsmanship thanks to the training she got from Hanyu.
* {{Matricide}}: She sacrifices her mother, Hanyu, in a ritual to atone for the village's sins.
* {{Miko}}: Much like Rika, Ouka served as one as her father was the priest of the Furude Shrine.
* NiceGirl: She was a very sweet and gentle person who only wanted to help others in trouble.
* NoGoodDeedGoesUnpunished: Ouka asked Hanyu to make a miraculous medicine to save the villagers from an epidemic, even though Hanyu warned her there could be bad consequences. Eventually, her medicine attracted the greed of others and the feudal lord as well as villagers wanted to steal the recipe from her, resulting in them attacking Ouka's husband and daughter and then violently interrogating Ouka. Hanyu went mad at seeing this and started murdering the villagers, forcing Ouka to kill her mother to stop her.
* OlderThanSheLooks: Interesting to say that near the end of ''Kotohogushi-hen'', she physically looks like a beautiful teenage girl if the same thing counts for Rika if she survives to the bitter end but it's confirmed she's 20 as Hanyu met her at the age of 10. The same length of years after Riku's tragic death.
* SecretSecretKeeper: Hanyu never told Ouka that she was her mother out of guilt over killing her father and abandoning her. Ouka reveals she did know her mother's identity... shortly before she had to kill her mother.
* SharedFamilyQuirks: When she's ten years old, she has the same {{Verbal Tic}}s as her descendant Rika, saying "Nippa" and "nano desu", the latter which is also said by her mother Hanyu after becoming a ghost.

----
* BestFriendsInLaw: She was Hanyu's best friend and they became in-laws when Hanyu's daughter Ouka married Shino's son Shouji.
* InterspeciesFriendship: She knew that Hanyu was a demon and that didn't stop her from caring for her as a dear friend.
* ParentalSubstitute: Due to [[spoiler:Riku's tragic death and Hanyu leaving the village for many years]], Shino raised Ouka as her own daughter until the latter was 10 years old. Even as an adult, Ouka thinks of Shino as her other mother.
* SecretKeeper: After she saw Hanyu's horns, she became the only one outside the Furude family who knew about Hanyu not being human and kept their secret.
* SlaveToPR: She acted hostile towards Mao Sonozaki even though she didn't really dislike her; she just felt the need of rejecting outsiders to keep appearances due to Hinamizawan customs.
[[/folder]]

[[folder:Mao Sonozaki]]
!!Mao Sonozaki
!!!Voiced by: Creator/MarinaInoue (JP)

The ancestor of the Sonozaki family. While she didn't get along with Shino Kimiyoshi, Ouka Furude accepted her as a close friend and sister figure.
----
* {{Irony}}: Despite the Sonozaki family's well-known hatred for outsiders, their ancestor Mao was in fact an outsider who moved to Hinamizawa from another town and this put her at odds with Shino Kimiyoshi.

An entity similar to Hanyu introduced in ''Higurashi Hou''. She holds contempt against Hanyu, leaving them in bad terms for a very long time.
----
* AdaptationalModesty: In the original release of ''Hou'', Tamura gets dragged into the club's punishment games and is made wear a skimpy bondage outfit that comes with {{Underboobs}} and bat-wings attached to her back. In the console version, her embarrassing outfit for the game gets significantly toned down to a SchoolSwimsuit.
* AntiquatedLinguistics: She speaks in a very archaic Japanese.
* FantasticRacism: She thinks very poorly of demons outside of her clan, such as Hanyū.
* GreaterScopeVillain: [[spoiler:The whole mess in ''Hou'' with Une trying to destroy humankind happens because Tamura refused to let Une live in a little piece of land and ''then'' didn't warn Hanyu about the Une virus because she's still mad about Hanyu eating one of her offerings.]]
* LostFoodGrievance: She knew the whole time that [[spoiler:Une was the biggest threat]], but refused to tell Hanyu about it because Hanyu once ate an offering given to Tamura.
* MercurysWings: She has feathered wings coming out of her head in a similar position to Hanyu's horns.
* NeverMyFault: She is very quick to blame Hanyū for [[spoiler:allowing the threat of Une to grow as much as it did]], even though the onus was on Tamura to warn Hanyū about it and [[WeWouldHaveToldYouBut she didn't]] because of a [[LostFoodGrievance petty grudge]].
* ReallySevenHundredYearsOld: She looks like a young girl, but has known Hanyu for centuries.
* RedEyesTakeWarning: She has red eyes that sometimes [[GlowingEyesOfDoom glow]] when she is angry.
* ShowgirlSkirt: Over her short red skirt, she wears a long black hakama skirt that splits down at the front to display her legs.

A girl introduced in ''Higurashi Hou''.
----
* AdaptationalModesty: Like Tamura above, the console version of ''Hou'' majorly tones down the embarrassing outfit of her punishment game from the original version, changing it from a revealing bikini to a SchoolSportUniform.
* AliensAreBastards: [[spoiler:Turns out to be a [[HumanAliens human-looking alien goddess]], which coincides with the reveal that she wants to annihilate everyone on Earth with a virus.]]
* AndThenWhat: [[spoiler:Rena asks Une what she planned to do after devouring everyone on Earth, pointing out that the only thing she could do was head for the next planet with life on it, and think how long that would take.]]
* AntiquatedLinguistics: As [[spoiler:a goddess]], she speaks in normal Japanese, yet uses the archaic pronouns that both Tamura and Hanyu also use.
* BitchInSheepsClothing: [[spoiler:She's introduced as a cute and shy little girl who helps out the club members when they're running from a deranged mob in Okinomiya in the midst of an outbreak of the Hinamizawa Syndrome. Her true self is an evil alien goddess with goals of omnicide.]]

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/rika_witch_mei_6.png]]
[[caption-width-right:300:[[labelnote:Click here to see her as a St. Lucia student]]https://static.tvtropes.org/pmwiki/pub/images/mei_rika_hs_14.png[[/labelnote]]]]


The protagonist of the second half of the ''Gou'' anime. Five years after ''Matsuribayashi-hen'', Rika finds herself thrown back to June 1983 for reasons she doesn't yet understand and Hanyu refuses to explain what's happening. Rika at first isn't too worried because she should break free of the loop more quickly than the first time as she already knows who is her murderer... Or so she thinks.
----
* AdaptationalIntelligence: The ''Meguri'' manga depicts her being more active and shrewd in trying to reclaim her future, knowing that she has to stop Takano quickly and prevent her friends from succumbing to paranoia. ''Oniakashi'' not only has her trying to quell Keiichi's suspicions, but also [[spoiler: inform Tomitake about Takano's plans and asking him to call the Bloodhounds for protection.]]
* AesopAmnesia: One of the most important lessons for the club members in the original series is the value of friendship and good communication. In ''Gou'', [[spoiler:post-''Matsuribayashi-hen'' Rika failed to properly maintain communication with her best friend Satoko after they enter St. Lucia and when Satoko started to drift apart, Rika focused on enjoying her new friendships instead of keeping the one she already had with Satoko.]]
* BludgeonedToDeath:
** At the start of Nekodamashi-hen, [[spoiler:a L5 Ooishi beats her head with a baseball bat until she dies]].
** Again at the end of Gou Episode 15, she's killed when [[spoiler:Keiichi]] hits her in the head with a baseball bat.
** Episode 14 of Sotsu has her die from this again during one of her looping fights with Satoko.
* BluffingTheMurderer: How she ultimately uncovers that [[spoiler: Satoko]] is the one screwing up the timeline. [[spoiler: She arranges a birthday party for Satoko and, for her final gift, hands her the box she used as a prank several timelines earlier that punches whoever opens it in the face with a boxing glove. Sure enough, Satoko winces away from it, then tries to cover by claiming that a TrapMaster can spot any trap from a mile away... only for Rika to open the box and reveal she'd replaced the trap with a teddy bear the previous night.]]
* BrokenTears: She cries in grief and despair when Hanyu vanishes in Episode 14 and leaves her to try and overcome the new time loops on her own.
* BustContrastDuo: As teenagers, Rika is still pretty flat-chested unlike Satoko who grew several cups. Given that Rika was looking forward to growing breasts after finally escaping the time loop the first time, this is quite ironic.
* ChairmanOfTheBrawl: As a nod to Saikoroshi-hen, Rika beans Satoko with a chair in retaliation for trying to brutally murder her.
* DecoyProtagonist: For most of Gou, it looks like Rika is the hidden protagonist to Keiichi's DecoyProtagonist like in the original series. After [[spoiler:Satoko]] is revealed to be the BigBad of Gou, the remainder of Gou and the entirety of Sotsu are told from [[spoiler:Satoko]]'s POV, making her the VillainProtagonist with the goal of breaking Rika.
* DeconstructedCharacterArchetype: Of the ClassPrincess. Almost immediately after arriving at St. Lucia, Rika's elegant ProperLady front gains the admiration and praise of her classmates. Rika never acts arrogant and remains the same good-natured person she always was, but there's some bad consequences to her high social position at school. [[spoiler:Rika's popularity and sophisticated behavior causes Satoko to develop an inferiority complex as she can't adjust herself to the school's stiff culture. Since she doesn't get along with Rika's groupies, Satoko distances herself from her former best friend. Rika does try to offer Satoko help at studying because she's honestly worried after Satoko gets sent to remedial classes, but Satoko takes this as Rika pitying her and distances herself even more.]]
* DontMakeMeDestroyYou: Subverted by Rika who gets fed up with the new BigBad's attempts to beat her into submission. She brings out a shard of Onigari-no-ryuuou and invokes its powers with the intent to slay her former friend for good.
* DramaticallyMissingThePoint:
** In Episode 14 of Gou, Hanyu's fragment tells her where to find the Onigari-no-ryuuou, explaining it has the power to kill off a looper permanently. [[spoiler:Rika can only assume that Hanyu is telling her to kill herself if she can't put up with the pain of being killed over and over again. It takes her a while to figure out Hanyu was warning her about ''another'' looper who is behind her gruesome deaths this time.]]
** [[spoiler:Whenever Satoko confronts Rika about her having a good time at St. Lucia while Satoko isn't, Rika just brushes it off as Satoko getting frustrated about her grades not doing that well. She either doesn't understand or underestimates how Satoko feels totally misplaced at St. Lucia and can't stand the ladylike behavior of other girls, including Rika, because she finds them snobbish. Also, Satoko is more frustrated with seeing that Rika isn't struggling academically while she is getting behind as that makes her develop an inferiority complex.]]
* EmptyPromise: [[spoiler:In Satoko's first repeat, she communicates with Rika everything that'll happen at St. Lucia in the future and tells her why she won't fit in at that place like can. Rika tries to dispel Satoko's fears by promising that she'll be there to help Satoko if she needs her. When things ''do'' end up the same as the first time around, Satoko accuses Rika of breaking their promise. Rika, however, insists she never lied to Satoko and did offer her help when she noticed Satoko's grades were falling, but Satoko can't interpret it as honest help when it's obvious Rika isn't struggling with academics like she does.]]
* EvenTheGirlsWantHer: She's almost worshipped by the girl population at St. Lucia. Satoko, however, has a crush/falls in love on Rika instead.
* ExpositoryPronoun: She switches from [[{{Bokukko}} "boku"]] - her younger self's preferred pronoun - to the more ladylike "watashi" when she goes to St. Lucia, but still occasionally slips up when she's not focusing or is around her old friends.
* GlowingEyesOfDoom: Her eyes turn a glowing purplish red at TheStinger of the first episode. And again, when snapping at Keiichi for entering Saiguden in Watadamashi-hen.
* GuttedLikeAFish: [[spoiler:In Episode 16, she has her guts ripped out of her body like when Takano killed her in the original series. Except her killer this time is not Takano, but Satoko. And worse, unlike Takano who at least knocked her out with chloroform, Satoko keeps her conscious the entire time.]]
* HalfTheWomanSheUsedToBe: A particularly gruesome example. [[spoiler: In Episode 16, Satoko performs the Watanagashi ritual on her, disembowling her and hacking at her intestines with the ritual hoe. By the time she is finished, the simple act of Satoko hugging Rika pulls the top half of her body off of what's left of the rest of her.]]
* InnocentlyInsensitive:
** [[spoiler:Rika notices Satoko is having troubles with her grades at St. Lucia Academy and tries offering her help for studying, which is a nice gesture. The problem is that Rika asked Satoko right in front of her new friends who already look down on Satoko and someone prideful like Satoko naturally doesn't want to admit she's failing at her grades in the presence of others.]]
** [[spoiler:In Satoko's second loop, Satoko tries talking Rika out of studying for the entrance exam of St. Lucia Academy. Rika then gets upset at Satoko implying it's wrong for her to pursue her dream of a life away from Hinamizawa and declares that even if Satoko doesn't want to study with her, she's going to study and enroll at the school on her own. Unfortunately, Satoko's abandonment issues make her interpret this as Rika basically threatening to abandon her if she doesn't go to St. Lucia with her.]]
* LivingEmotionalCrutch: Satoko is extremely attached to Rika due to her being the main reason she could start enjoying life again after suffering years of abuse and losing her brother. Problem is, that emotional dependence turns into an unhealthy possessiveness as they become teenagers [[spoiler:which pushes Satoko to start the tragic time loop all over again to keep Rika to herself because she just doesn't have the emotional stability to even try building a happy life that doesn't involve having Rika at her side 24/7.]]
* TheManyDeathsOfYou: Episode 15 is basically a sequence of Rika being killed in different painful ways by L5 killers. This happens again in Episode 14 of Sotsu only this time she's willing to fight back during the second half of those loops.
* MidSuicideRegret: In Episode 14, [[spoiler:Rika considers putting herself out of her misery for good with the small shard of the sword Onigari-no-ryuuou since getting thrown back into the loop where she gets killed endlessly is too much. Then she hears the club members looking for her at Saiguden and she decides it might be worth it to try a few more loops before giving up completely.]]
* OffWithHerHead: One of her many deaths in Episode 15 is being decapitated by [[spoiler:Akane]].
* {{Ojou}}: She's technically high-class among Hinamizawa because the Furudes are one of the Three Great Families and she's universally adored by the townsfolk. At St. Lucia Academy, her refined behavior makes the other students [[spoiler:who are not her longtime friend Satoko]] look up to her like if she was a beautiful princess. Only the club members treat her like a normal person.
* PinballProtagonist: Although Keiichi is the POV character for the first half, Rika is the true protagonist of Gou. However, despite her statement early on that she would try to fight fate harder, the first half of the series is her acting as a passive observer in the slightly changed scenarios that end in her and her friends' deaths all over again. The only actions she takes are trying to clear Keiichi's suspicions about Rena in Onidamashi and suggesting him to give Mion in Watadamashi, but the changes in the scenarios cause tragedies to happen anyway and Rika doesn't actively investigate why she and her friends are dying again. It takes her 17 episodes to even [[spoiler:talk to Takano before she escapes with Tomitake, confirming that Takano isn't her killer this time]].
** She averts this in ''Meguri''. ''Oniakashi'' reveals that not only did try to calm down Keiichi but she also [[spoiler: told Tomitake about Takano's evil plans and convinced him to call the Bloodhounds to protect the both of them, leading to his survival and Takano's plans being cut short.]] Overall, this makes Rika more proactive and has her statement about fighting fate have actual weight.
* PleaseDontLeaveMe: In Episode 14, she starts to fall into despair when she sees Hanyu's spirit fading in the sea of fragments because she never wanted to face more deadly loops without Hanyu.
* PoorCommunicationKills: [[spoiler:The fall out between her and Satoko in St. Lucia Academy that eventually traps them both in the loop again could have been avoided if the two had a proper conversation before or shortly after enrolling at the school. Rika invites Satoko to go to St. Lucia with her because she assumed Satoko would love it as much as her. When Satoko doesn't seem happy at all and gets sent to extra lessons, Rika thinks she's just having trouble with her studies and offers her help, but as Satoko keeps rejecting her, Rika stops even trying to reach out and focuses on enjoying her new life by herself. As a result, Satoko's negative feelings about her situation and resentment towards Rika for "causing" it grow bigger over the year.]]
* ProperLady: At St. Lucia, she adjusts herself to the elite school perfectly by behaving like an ideal prim lady. [[spoiler:However, this causes Satoko to distance herself from her because the Rika she likes isn't so sophisticated.]]
* RageBreakingPoint: When Rika learns who's been screwing with her attempts to escape the loops, she furiously condemns their motivations for doing so and fights back hard.
* TheReasonYouSuckSpeech: [[spoiler:Angrily calls Satoko out for her bullshit after learning she's the other looper and being subjected to another series of brutal loops.]]
* RedEyesTakeWarning: Her eyes glow red when she drops the cute act and goes into CreepyChild mode in front of Keiichi.
* SchoolIdol: She's idolized by the high-class girls at St. Lucia because of her elegance and refined manners. The other students [[spoiler:except Satoko]] call her "Rika[[UsefulNotes/JapaneseHonorifics -sama]]".
* SoreLoser: In the first episode of Gou, she pretends that she has no ill feelings over Satoko using her traps to beat her in the club's first game with Keiichi. Then, she gives her a box that springs out a boxing glove and punches Satoko's face.
* StoppingTheBlameGame: [[spoiler:In the first repeat of their life in St. Lucia Academy, Satoko perceives Rika once again going to have tea parties with her GirlPosse instead of staying by her side as the ultimate betrayal of her best friend. When Satoko confronts her about breaking her promise to be there for her, Rika defends herself by reminding Satoko that she did offer her help at studying and Satoko refusing out of pride is on her. Rika doesn't seem to understand Satoko is angrier about Rika spending all her time with her groupies when she knows Satoko is falling behind in her grades.]]
* TeaIsClassy: At St. Lucia, she spends her free time having tea parties with her GirlPosse who love to hear her poetic speeches.
* TomboyAndGirlyGirl: The Girly Girl to Satoko's Tomboy. Rika is much more polite and feminine compared to her haughty and loud best friend. This gets PlayedForDrama when [[spoiler:Rika gets accepted by the rich girls at St. Lucia for her ladylike behavior while Satoko's bad-mannered personality doesn't fit in at the school and drives her to alienate herself from everyone.]]
* TragicMistake: [[spoiler:Rika had every right to seek out a new life outside of Hinamizawa after escaping the loop where she was trapped for 100 years, but she made the big mistake of expecting Satoko to share her dream of going to St. Lucia Academy. Rika doesn't seem to fully understand that Satoko is only following her out of abandonment issues. As a result, she focuses on enjoying her new life and friendships while neglecting Satoko's deteriorating emotional and mental state due to stress and isolation at the school. The most she tries to do for Satoko is offering her help at studying when she notices Satoko's grades are falling, but Satoko is too prideful to accept her help. After Satoko's prank on Rika goes terribly wrong and injures one of Rika's new followers, Rika stops trying to reach out to Satoko and pretty much lets their friendship end. This has horrifying consequences for Rika when Satoko runs into a godlike being who grants her magical powers to rewind time and once Satoko realizes she can't change Rika's mind about going to St. Lucia in the good way, then she's gonna destroy Rika's mind and will by making her go through torture and death until Rika can't ever think about leaving Hinamizawa and being apart from Satoko again.]]
* TraumaCongaLine: As if being stuck in a time loop where she sees her friends becoming crazy killers and she's killed gruesomely over and over for 100 years wasn't enough, Rika gets thrown back to June 1983 yet again after experiencing a few years of peace and happiness. Even though she should know how to prevent the same tragedies to repeat, she and her friends keep dying. After three failed loops, Rika seriously considers killing herself permanently with the shard of the sword Hanyu left her, but having her friends makes her think she should try five more times... What follows are five loops of absolute ''Hell'' where she's killed in even more painful and brutal ways than before. To make it infinitely worse, people she cares about and trusts more than anyone [[spoiler:like Akasaka, Keiichi, and Satoko]] become her killers.
* WalkingSpoiler: All information regarding Rika in Gou spoils her true significance in the original series.
* WiseBeyondTheirYears: One of the reasons why Rika is so admired by other girls at St. Lucia is because she can act so mature and cultured despite being only 16-17 years old. It's {{justified|trope}} as Rika is mentally over a hundred years old.
* WrongGenreSavvy: At the start of Gou, Rika thinks she's in the Onikakushi-hen scenario and to prevent Keiichi from succumbing to the Hinamizawa Syndrome and killing his friends, she tries to reassure him that Rena's scary behavior is all in his head and he should believe Rena isn't plotting to hurt him. Alas, this isn't Onikakushi-hen, it's a new arc named Onidamashi-hen [[spoiler:and Rena does want to kill Keiichi here since she's the one with the Hinamizawa Syndrome this time around]].

Satoko Houjou after the events of ''Matsuribayashi-hen'', the second looper in the fragments of ''Gou'' and the main villain of the series.
----
* ActOfTrueLove: Subverted. After she understands Rika won't simply give up on going to St. Lucia Academy, Satoko accepts Rika's request to follow her again to make Rika happy despite Satoko hating the academic pressure she feels at that school. Once they end up in the same situation as in the first loop (Satoko at remedial classes while Rika is enjoying herself with her new friends), Satoko snaps completely and decides it isn't worth it to put up with all that stress and frustration at St. Lucia if she isn't even going to be a part of Rika's newfound happiness. Therefore, she takes away Rika's happiness by dragging her back to June 1983 all over again and is going to do whatever it takes, including torture and brainwashing, to convince Rika to stay in Hinamizawa where Satoko's happiness is.
* AdaptationalAngstUpgrade: The ''Meguri'' manga that provides different answer arcs from the anime tremendously amps up the mental and emotional pain Satoko had to go through in her loops. First, she's shown to have been locked up in a room where she was forced to do nothing but study 24/7 for several weeks, leaving her completely drained from the stress and isolation. Eua appears to her and offers her the chance to redo her choices in different timelines. However, every single path she takes results in either Rika or Satoshi dying and her being left alone to then either die in an accident or commit suicide. After countless loops of tragic endings, Satoko is just a shell of herself.
* AdaptationalSympathy: Her StartOfDarkness is way more tragic and sympathetic in the ''Meguri'' manga where she initially does try to make much more reasonable and peaceful choices to avoid her fall out with Rika as opposed to her ''Gou'' anime self who kills Rika and herself as soon as Rika refuses to give up on St. Lucia. Unfortunately, Eua sends Satoko to timelines where Rika and/or Satoshi die in situations out of her control, which sends Satoko past the DespairEventHorizon and convinces her that she must recreate the GroundhogDayLoop of June 1983 since there's no happy future after it.
* AdaptationalVillainy: While a mischievous brat, Satoko in the original series was nevertheless one of the "heroes" who cared for her friends. In ''Gou'', her fear of being left alone takes her down a dark path where she devolves into the BigBad.
* AesopAmnesia: PlayedWith. In the ''Minagoroshi-hen'' arc, Satoko was finally able to understand that bottling up her emotions and trying to handle everything by herself wasn't real strength, and realized the importance of asking her friends for help. This lesson, however, doesn't seem to have entirely passed over into the ''Matsuribayashi-hen'' timeline, which the ''Gou'' anime is a sequel to. While she does openly express to Rika her worries and concerns about attending St. Lucia (once she's already suffered through them anyway), she does still wind up making the same mistakes of hiding behind bravado and letting her pride get the better of her when both her grades and relationship with Rika start to suffer upon enrolling in St. Lucia. Granted, these are also very different circumstances, but it's still unfortunate.
* AllTheOtherReindeer: Much like in Hinamizawa, Satoko is an outcast at her new school, both for her inability, or even outright refusal, to conform like everyone else, as well as her slipping grades due to a lack of motivation. Contrary to Rika who is able to adjust rather flawlessly, much to Satoko's frustration and disbelief.
* ApatheticStudent: She enrolls at St. Lucia Academy because she wanted to stay close to Rika, but she dozes off or doodles instead of paying attention at class and gets mad when the teacher sends her to remedial classes. Satoko would be happy to drop out from the school as she has the freedom to do that unlike many of the girls there and the only reason why she even tries to study is because she doesn't want to be apart from Rika.
* ArchEnemy: She becomes this to Rika largely due to coming to resent her for choosing to enjoy her school life at St. Lucia without Satoko even though she knows Satoko only went to a school she hates because of her.
* AsleepInClass: She falls asleep on her very first day attending class at St. Lucia Academy.
* AttentionDeficitOohShiny: ''Not'' PlayedForLaughs, but rather quite realistically. Satoko is all but stated to have ADHD. When Rika is motivating Satoko somehow, she can be laser-focused to a ''terrifying'' degree when chasing Rika over hundreds of fragments; but when Rika distances herself from Satoko, she ''physically can't'' motivate herself without a tangible goal and gets utterly crushed by St. Lucia's relentless curriculum. Rika leaves Satoko to fend for herself at St. Lucia thinking she'll learn how to motivate herself, assuming Satoko's problem is simple laziness, but in truth it's a deeper issue that Rika ends up making worse.
* BerserkButton: After the second loop, Satoko comes to hate lies as much as Rena as she will '''not''' let Rika try promising her to stay her friend at St. Lucia when she already broke that promise twice.
* BigBadFriend: Rika has always thought of Satoko as her best friend, but in ''Gou'', Satoko becomes the BigBad who traps Rika at a GroundhogDayLoop once again all because Satoko refuses to accept a future where she and Rika aren't best friends anymore.
* BigBadSlippage: ''Satokowashi-hen'' shows the increasing antagonism between her and Rika, and the resultant StartOfDarkness that drove her to recreate the infernal GroundhogDayLoop out of a petty desire to keep Rika in Hinamizawa and break her mentally.
* BookDumb: While not good at academics, Satoko becomes more dangerous by using her wits.
* BreakTheCutie: Her backstory in Gou is her going from a cheerful young girl to an utterly unhappy teenager who is frustrated and resentful about her school life. Satoko was perfectly happy at Hinamizawa, but her best friend Rika wanted a high-class life at St. Lucia Academy, so she invites Satoko to join her because she wants to share that goal with her. Satoko agrees, but not because she likes the school; she only wants to stay close to Rika who is like family to her. She studies hard with Rika to get into St. Lucia Academy, and, against all odds, she makes it. However, while her friend is able to adjust to the school, Satoko could not. She doesn't have much interest in the lessons and her grades fall after the first day thus forcing her to take up remedial classes. Other girls look down on her for not being well-mannered like Rika and although Rika does tell the girls to not badmouth Satoko because she's her friend, Satoko doesn't have any interest in being friends with high-class girls and this causes her to push away from Rika as she doesn't get why Rika can get along so well with elitist rich girls. Satoko is then forced into solitary confinement when her prank on Rika gets one of Rika's GirlPosse injured and Satoko is under the wrong impression that Rika ratted her out when it was really one of Rika's GirlPosse. Her grades don't get better despite the remedial classes and spends the next year stressed and isolated at the school as Rika stopped trying to reconnect after Satoko turned down her offers to hang out and study together.
* BrilliantButLazy: Satoko is a very clever girl and she can get good results academically when she puts real effort into it, as she was able to get into St. Lucia Academy with Rika after studying every day with her for two years. After she arrives at St. Lucia, however, Satoko can't get motivated to study if she can't spend all her time with Rika like before and doesn't even try paying attention at class. It's no wonder her grades drop quickly and she needs to be sent to remedial classes to make up for slacking off at the school.
* BustContrastDuo: She has much bigger breasts than Rika who is still flat-chested when they're teenagers.
* CharacterTic: She's taken up the habit of snapping her fingers right before she does something, typically, it involves one of her traps about to activate.
* TheChessmaster: She is pretty good at quickly adjusting her plans if something were to pop up. After watching all the loops where Rika suffered for hundreds of years, Satoko quickly sets to work creating wedges to disrupt Rika's attempts at escaping the loop. It becomes clear towards the end of ''Gou'' that she also stole a sample of the drug that causes L5 of the Hinamizawa Syndrome and injected it in targets that she anticipated Rika would try to get to help her. She even ups the manipulation like when she faked having a traumatic episode.
* ContrastingSequelAntagonist:
** To [[spoiler: Miyo Takano]]; most of what [[spoiler: Takano]] was able to accomplish was largely due in part to the backing she received from [[spoiler: Nomura]] and the Tokyo organization. At the end of the day, she was a mere human who aspired for godhood to make her grandfather's work recognized. With Satoko, however, what sets her apart from her predecessor is the fact that she literally has the power to rewind time with her own death powers due to a godlike being taking an interest in her, as if Rika already didn't have any less of a chance of escaping this loop. Also, [[spoiler:Takano]]'s goal by murdering Rika had zero personal connection to her relation with Rika and she didn't even know that Rika's soul would go to a new fragment after that. On the other hand, Satoko is putting Rika through all the torture and death because of her obsession with having her best friend all to herself forever and only gains the will of murdering Rika when she knows for sure that time will restart anyway.
** Also Shion Sonozaki. While getting revenge for Satoshi's disappearance was part of her motivation, Shion was ultimately aiming to kill the Three Families out of paranoia that they would kill her as well as lashing out at the ghastly abuse she faced from her own family. She also mainly committed the murders because of her reaching L5 of the Hinamizawa Syndrome at the time. But ultimately, Shion realizes that all her victims were innocent and expresses a hint of remorse before her death. There is much less remorse on Looper Satoko's end; [[spoiler: she ends up relinquishing Satoko's humanity and leaves Hinamizawa alone for good due to boredom and dissatisfaction rather than regret.]]
* CosmicPlaything: In the ''Meguri'' manga, it's heavily implied that Eua is deliberately throwing Satoko into bad timelines to keep herself entertained as she watches Satoko's endless struggle. Unlike the anime where she was the one causing the tragedies to stop Rika from leaving her, Satoko's happiness keeps getting ruined because Rika dies in an accident if she tries to leave Hinamizawa and Satoshi's condition worsens after Irie fails to find a cure for him.
* CountryMouse: Feels she is seen this way by the girls of St. Lucia and that she's incapable of fitting in with their "stuffy high society".
* DeathActivatedSuperpower: Like Rika, a godlike being grants her the power of rewinding time by dying.
* {{Dismotivation}}: Perhaps one of her biggest faults is that she refuses to accept the changes in her life after ''Matsuribayashi-hen''. Basically, she wanted everything to stay the same as in the days she played games with her friends at the club. After her older friends graduate and Rika makes new friends who Satoko doesn't like at St. Lucia Academy, Satoko comes to resent the future she lives in and instead of trying to adapt, yearns to go back to the old days where she was the closest person to Rika. This eventually drives her to restart the GroundhogDayLoop so everything is back to the status quo of the original series.
* DisproportionateRetribution: Satoko makes Rika swear that'll be best friends forever even after entering St. Lucia Academy despite them drifting apart in the previous timeline. And then Rika once again goes and makes friends with the rich girls while Satoko stops hanging out with her for her own petty reasons and blames Rika for not being at her side all the time even though Rika did try to reach out only for Satoko to turn her away out of stubborn pride. But how dare Rika "betray" Satoko by breaking their promise? Satoko's gotta drop a chandelier on her and force her to relive the nightmarish GroundhogDayLoop of torture and death she finally escaped from after 100 years. [[InsaneTrollLogic That's the only way they can be best friends forever and Satoko can get back at Rika for breaking her promise of enjoying the school with her twice.]]
* DontYouDarePityMe: The reason why Satoko rejects Rika's help during the second St. Lucia loop. After Satoko's grades start to drop at St. Lucia Academy, Rika offers to help her study, but Satoko, likely with some lingering bitterness from the first loop, sees Rika's attempts to help as nothing more than disingenuous pity, especially from someone who is in a much better position both socially and academically. Rika insists that this isn't the case and that it's just Satoko making paranoid assumptions.
* DramaticallyMissingThePoint: Satoko seems to believe that the way Rika's behaving upon arriving at St. Lucia Academy, so different from the best friend she's known for years, is just her putting on a persona to fit in with the new environment, and "just a phase" that she'll likely get over, and finds it frustrating and difficult to connect with her, contributing to her feelings of ostracization. The unfortunate irony being that Rika's more sophisticated personality is in fact actually closer to the real her, and the one that Satoko had been interacting with up to this point was the façade. Indeed, when Rika is seemingly able to suddenly and flawlessly transition back to her pre-St. Lucia personality, complete with the first "Nipah~" Satoko's heard in months when reunited with Mion and the others, Satoko's at a complete loss.
* DrivenToSuicide: After acquiring looping powers, Satoko goes as far as to kill herself when restarting a loop. She'll even do it at a moment's notice when the slightest thing goes wrong, as when she initially tries more peaceful ways to convince Rika to stay in Hinamizawa.
* EasilyForgiven: While Satoko's actions were horrible, Rika can't hold it against her, knowing one of the driving factors in Satoko's StartOfDarkness was Rika's own willful ignorance of Satoko's suffering.
* EntitledBitch: While she had suffered, Satoko stubbornly wants everything to remain the same and comes to antagonize Rika because her dream conflicted with her own. She refuses to accept blame at the bitterness of her drifting apart from Rika due to Rika's happiness not coinciding with hers. Instead of just letting Rika live her life, Satoko is determined to deprive her friend of her happiness because ''she'' felt wronged.
* EtTuBrute: PlayedWith. After starting a loop for the first time, Satoko tries communicating her fears to Rika about why she doesn't want the two of them to go to St. Lucia Academy and makes Rika promise her to not abandon her when she's in trouble. But then Satoko once again sees Rika having fun with other girls at tea parties while Satoko's grades fall again. Satoko takes this as the ultimate betrayal and calls Rika a traitor, causing her to snap and start the GroundhogDayLoop where she'll have Rika murdered in painful ways over and over... Except Rika again ''did'' offer to help Satoko study and tried to involve her in her new life, but Satoko always turned away because she believed Rika is looking down on her so their falling out is far from Rika's fault alone and [[NeverMyFault Satoko doesn't want to admit that]].
* EvilAllAlong: Episode 17 of Gou reveals Satoko's identity as Rika's enemy looper. The following arc shows her StartOfDarkness and reasons why she came to resent Rika enough as to be willing to kill her repeatedly just to change her mind about leaving Hinamizawa.
* EvilCounterpart:
** To Rika. Both are young girls who are given the power of rewind time with their own deaths. But while Rika wished for herself and all of her friends to escape the tragic GroundhogDayLoop of June 1983 and create a happy future, Satoko is dragging all of her friends into MurderSuicide in order to ''preserve'' the loop because she prefers to keep herself and her friends stuck in June 1983 eternally than arriving at a future where all her friends go their separate ways and she becomes estranged from Rika.
** And to Shion, or probably an "eviler" counterpart. Much like Satoko, Shion was a {{Yandere}} who murdered a lot of people. However, Shion never harmed the target of her obsession and only became a murderer due to her Hinamizawa Syndrome and the Sonozakis purposely making themselves suspicious of the Watanagashi disapperances making her convinced that they killed Satoshi. Additionally, she has a HeelRealization where she realizes that all her victims were innocent and kills herself as she ponders whether she could start over. With Satoko, however, she is ''incensed'' with Rika for seemingly betraying their promise and suffers from NeverMyFault not listening to Rika when she pointed out that ''she'' was the one who drifted from her. Satoko then proceeds to brutally murder Rika and their friends, not feeling even a bit of guilt as she reasons that she can undo her crimes as many times as she wants with her MentalTimeTravel powers.
* EvilIsPetty: In ''Satokowashi-hen'', which is her StartOfDarkness, Satoko is portrayed as an egotistical and rude girl who acts disrespectful towards everyone in St. Lucia Academy because she hates their formal manners and demand for exceling academic performance. She's also toxically over-dependent and possessive of Rika, ultimately dragging Rika back to June 1983 by pulling a brutal MurderSuicide with a FallingChandelierOfDoom, all because she felt betrayed when Rika didn't keep her promise of continuing to be best friends with Satoko at St. Lucia, even though Satoko is the one who pushed away from her due to Rika making new friends and Satoko refuses to acknowledge she's creating the distance between them in favor of playing the victim in their conflict.
* {{Expy}}: Although Satoko was in fact created by [=Ryukishi07=] first, her character and motives in ''Gou'' are obviously based off of Lambdadelta from ''VisualNovel/UminekoWhenTheyCry'' as Satoko devolves into a blonde PsychoLesbian {{Yandere}} obsessed with a blue-haired "cat" who she claims to love while wanting to trap and torture her for eternity. Satoko even uses the word "certain" several times, a reference to Lambdadelta being the Witch of Certainty. [[spoiler: Taken a step further in light of the "Another End" web novella released in 2022, where her witch is confirmed to be, or at least become, Lambdadelta in the closing pages.]]
* FaceHeelTurn: Satoko was one of the main heroes in the original series. In ''Gou'', she's the BigBad who's knowingly trapping herself and her friends in the GroundhogDayLoop of June 1983 because she selfishly wants them to be together in the same place forever.
* FangsAreEvil: Her fang is constantly sticking out. It looked like CuteLittleFangs at first until she's revealed to be the new BigBad.
* ForTheEvulz: Her injecting Mion with the Hinamizawa Syndrome was largely because she wanted to see how Mion would kill people under the influence of it since she never fell victim to it in the previous loops. In fact, a lot of her behavior on the side of her mission to break Rika's spirit and keep her in Hinamizawa can be boiled down to ItAmusedMe.
* FreudianExcuse: Given her complete lack of a stable home life throughout her childhood until she started living with Rika, Satoko's negative reactions to all the drastic changes in her environment and relationships certainly make sense. Not that it justifies even remotely how Satoko eventually decided to abuse her MentalTimeTravel powers and torture Rika inhumanly all in order to make sure Rika stays at Hinamizawa forever and Satoko can have her all to herself.
* {{Gaslighting}}: She convinces Rika that all the pain and misery she's going through in her new time loop is Oyashiro-sama's punishment for wanting to leave Hinamizawa, when it's really Satoko herself. Despite being very close to the actual Oyashiro-sama, Rika nearly falls for it.
* AGodAmI: Satoko decides to make herself the new Oyashiro-sama who'll curse Rika for wanting to leave Hinamizawa.
* GoodGirlGoneBad: Satoko started off as a fairly decent person who only wanted to be close to her best friend even if it meant following her to a school she hates. Unfortunately, through several issues of [[PoorCommunicationKills poor communication]], stress, and dislike towards the formal environment of the school and its students, Satoko becomes depressed. Then she comes across a godlike being who grants her MentalTimeTravel powers and gives her the chance to get back the life with Rika that she liked, only for the same cycle to repeat all over again due to Satoko blaming Rika for "abandoning" her even though ''Satoko'' is the one who pushes away due to selfish pride. All this leads to Satoko choosing to abuse her new powers as a looper and torture Rika in the loops until Rika's mind breaks and she never defies Satoko's wishes ever again.
* GreenEyedMonster: While she was alright with hanging out with the other club members because she was still Rika's #1 friend back then, Satoko quickly develops destructive feelings of jealousy for Rika's GirlPosse at St. Lucia Academy, even refusing to hang out with Rika if those girls are around and hating to see Rika enjoying herself at tea parties with them instead of her. After she loops for the first time, Satoko snaps at seeing Rika making friends with her GirlPosse again and decides that this time, she'll trap Rika in Hinamizawa so she'll never be able to make friends with other girls and Satoko will be her only best friend forever.
--> '''Satoko:''' Tell me, Rika. Do you remember what you said to me? You said you wanted to experience this life together with me. Tell me, Rika. What is... ''the meaning of this?''
* GroundhogPeggySue: She's depicted this way in the ''Meguri'' manga. Satoko finds herself trapped in the GroundhogDayLoop created by Eua where she must keep taking different choices until she finds a timeline where she doesn't have to lose either Rika or Satoshi. However, tragedy keeps striking at the end of the loops no matter what path she tries to take.
* HatesBeingAlone: She's got very serious abandonment and dependency issues because of her harsh childhood. As much as Satoko hates being at St. Lucia Academy where she feels ignored by Rika, she doesn't drop out because none of her friends are at Hinamizawa anymore. The mere concept of living alone at the village is unthinkable for her.
* HeelFaceTurn: The human side of Satoko is able to somewhat let go of Rika and allow her to fulfill her own dreams. [[spoiler: The looper/"witch" side of her, however, commits to chasing Rika down forever, which Rika has accepted by the end.]]
* HiddenVillain: At the end of episode 17, she is revealed to be the villain when Rika tricks her to reveal that she knew about a trap Rika has set. Satoko's eyes [[RedEyesTakeWarning immediately blaze red]], and she pulls a gun on Rika. The next arc focuses on her [[JumpingOffTheSlipperySlope road to villainy]] and why she's trying to force her own happiness on Rika.
* HoistByHerOwnPetard: Satoko finally realizes how monstrous she was behaving, but she couldn't do much against her more powerful witch self, who takes dominance for the remainder of the series [[spoiler:until the very end.]]
* HopeCrusher: Satoko's main goal is utterly crushing all hope Rika had for a happy future after finally escaping the loop of June 1983, all in order to make her stop dreaming about a life outside Hinamizawa.
* HopeSpot: Satoko doesn't want to endure St. Lucia a 2nd time, honestly speaks to Rika about fears. Rika promises to help her... then proceeds to do the same thing as in the original loop.
* {{Hypocrite}}: When having a heart-to-heart with Rika in her second loop, Satoko claims that she's going to go to St. Lucia for the sake of Rika's happiness. The moment she sees that, once again, Rika's happiness at St. Lucia isn't ''her'' happiness too and she isn't even needed for Rika's happiness either, Satoko doesn't hesitate to utterly destroy the happiness Rika worked so hard to obtain by murdering her and dragging her back to June 1983 once more all so she can force her own happiness on Rika.
* IfICantHaveYou: At the end of her second loop, Satoko finally snaps at seeing Rika once again hanging out with her GirlPosse of refined girls. Since she can now see that Rika is going to meet and hang out with these girls instead of her as long as they go to St. Lucia, Satoko commits MurderSuicide with Rika by [[FallingChandelierOfDoom dropping a chandelier on them]] and declares that she'll make sure the future where Rika chooses those high-class girls over her won't come to pass ever again.
* IgnoredEpiphany: While in solitary confinement, Satoko does wonder why she decided to go with her best friend to a school she despised. However, [[NeverMyFault she shifts to further blaming Rika for her plight]].
* INeverSaidItWasPoison: In the first episode, Rika pulls a prank on Satoko by giving her a box only to press a button that causes a boxing glove to punch her in the face. At the end of Episode 17, Rika gives Satoko the same box as a birthday present. Satoko immediately kneels down to avoid the punch. But many loops have passed since the first episode and Rika changed the contents of the box for a teddy bear. Therefore, Satoko's reaction wouldn't make sense unless she remembers previous loops like Rika. This is how Rika exposes Satoko as the other looper who is behind her and her friends' gruesome deaths in the new loops.
* {{Irony}}:
** She likes to present herself as a refined highborn noblewoman, but as soon as she transfers to a school filled with actual high-status girls where her hyper-polite speech doesn't sound out of place, she finds out the hard way that she is way out of her element and hates it.
** She actively becomes a ''much'' crueler person around the same exact time her {{Jerkass}} abusive uncle Teppei is [[TheAtoner trying to be a much kinder person.]]
* ItsAllAboutMe: Her main motivation for everything. All Satoko thinks about is how she wants all of her life to stay the same as in the days she was Rika's #1 friend and they played at the club together. After they achieve their happy ending, everyone in the group starts going separate ways as they grow older and can't spend time together as before. In this future, everyone is happy except for Satoko who is the only one who doesn't try to find her own path in life and keeps trying to cling on to Rika, but their friendship falls apart after Rika develops new interests and makes new friends at St. Lucia that just don't match Satoko's tastes. So, after getting magical MentalTimeTravel powers, Satoko rips away all of her friends from their happy future and throws them back into the GroundhogDayLoop of June 1983 along herself, all so she can have the life ''she'' likes better back even if it means dooming her friends to be murdered endlessly for her own utterly selfish wish.
* IveComeTooFar: At the end of ''Sotsu'' episode 10, in the sea of fragments, Satoko realizes her own follies of preventing Rika from leaving Hinamizawa and making her stay there forever as she inadvertently creates the 'witch' version of herself who is determined to possess their own body to resume her goal by killing those close to her like the club members and Teppei who had already turned over the new leaf to become much kinder to her which causes her to realize that all she wanted all this time was to make sure her best friend was by her side to be loved as Eua rubs her in for being entertaining but it was already too late for her to amend her own actions as her witch self use her gun to 'kill' her and resumes killing Teppei.
* JerkassHasAPoint:
** Satoko behaves very rudely and disrespectfully towards Rika and her GirlPosse when confronting Rika, earning her the spite of the GirlPosse and Rika has to demand her to shut up so Satoko stops making a scene in public. Yet, Satoko does bring up some legitimate grievances to Rika about how hard she had to work to get into St. Lucia, at Rika's request, only to find herself feeling excluded and stressed every day upon attending. Doesn't help that Rika only seems to dismiss her feelings as "just a foul mood" when she leaves.
** During her outburst in the third loop, Satoko yells at Rika for insisting on going to St. Lucia together despite Satoko already speaking about how Rika will strive while Satoko will only feel miserable at that school. While Satoko is being too emotional and resentful due to feeling betrayed by Rika in past loops, she does point out how Rika keeps saying she wants them to enjoy the school "together" when she's actually imposing her own dream on Satoko and arbitrarily expects Satoko to tag along for her own comfort, as studying alone would be more boring.
* KickTheDog: She does many cruel things to her friends for the sake of seeing what would happen and if it'd make Rika's life more of living Hell.
* KiddieKid: PlayedForDrama. After the events of ''Matsuribayashi-hen'', Satoko is the only member of the club who doesn't show signs of maturing and still wants to play with her traps while Rika is developing more grown-up interests. This becomes a problem when she and Rika enroll at St. Lucia high school, as Satoko feels suffocated in that demanding elite school and the other students find her quirks like her NoblewomansLaugh to be unfit for the high-class culture of their school.
* LackOfEmpathy: Despite the fact she knows what Rika has sacrificed to get to an ending where she can live peacefully and away from Hinamizawa, Satoko is only concerned that she was "abandoned" by her and makes it her goal to force Rika to give up her dream by breaking her will.
* LovingAShadow: Possibly the biggest source of conflict between her and Rika is that Satoko doesn't simply want to be with Rika; she wants the Rika who acts all cutesy and playful, not the ProperLady {{Ojou}} version of Rika that she becomes at St. Lucia Academy. Unfortunately, Satoko doesn't know nor understand that the Rika she adores so much is a [[DeliberatelyCuteChild mere facade]] that Rika got used to putting up while at Hinamizawa as she spent 100 years looping and pretending to be a clueless child to not draw attention. Once Satoko realizes Rika can only be the Rika she wants at Hinamizawa, she chooses to change Rika's mind about leaving Hinamizawa even if she must break Rika's will through ever-repeating torture for it.
* LowerClassLout: She's from the countryside, and her attitude and inability (or rather refusal) to adapt to St. Lucia Academy's prim and proper environment makes her stand out like a sore thumb in a negative way and become an object of derision by her peers.
* ManipulativeBitch: When she loops for the first time, Satoko tries to prevent the future where she follows Rika to St. Lucia by trying to talk Rika out of it and deliberately obstructing her attempts to study. After that doesn't work, she restarts the GroundhogDayLoop where Rika is painfully murdered which culminates in Satoko performing [[GuttedLikeAFish Watanagashi]] on Rika while convincing Rika that all the reason why she's suffering like this is because she wished to leave Hinamizawa for St. Lucia Academy so Satoko can get exactly want she wants; having Rika all to herself.
* TheMole: For most of ''Gou'', Satoko seems to be in the same role of the original series as a member of the club's band of TrueCompanions. Episode 17 reveals she's in fact the other looper who has been orchestrating the tragedies in the new loops because she's trying to break Rika's will and force her to give up her dream of going to St. Lucia Academy.
* MortonsFork: From the point she accepts to follow Rika in St. Lucia, Satoko has only two options − either try to fit in with the high-class girls to stay close to Rika, something she's neither able nor willing to do, or drop out of the school and start a new life away from Rika, [[LivingEmotionalCrutch something she can't conceive.]] Naturally, Eua finds this the perfect opportunity to make Satoko a looper.
* MundaneUtility: She uses her MentalTimeTravel powers to perfectly memorize a card game.
* MurderSuicide: After failing to talk Rika out of going to St. Lucia Academy and seeing Rika spend time with her GirlPosse instead of her again, Satoko chooses to restart the loop and kills herself along with Rika by [[FallingChandelierOfDoom dropping a chandelier on both of them]].
* MyGodWhatHaveIDone: She's shocked when she realizes her DropTheWashtub prank made one of Rika's GirlPosse bleed because she was used to the AmusingInjuries back in the club. Still, she didn't feel guilty enough to admit her blame and was found out because one member of Rika's GirlPosse rats her out.
* NeverMyFault: During the scene where she's performing the [[GuttedLikeAFish Watanagashi]] on Rika, Satoko goes on a rant about how this is the punishment Rika deserves for wishing to leave Hinamizawa and that she had to dirty her hands by murdering all of their friends is all Rika's fault. Once we're shown the flashback of Satoko's StartOfDarkness, it's revealed that while Rika did play some part in making Satoko hate the future by taking her to St. Lucia with her, Satoko played an even bigger part in them stopping being friends. Satoko grows to resent Rika for seemingly forgetting their promise to enjoy their life at St. Lucia together and envies her for thriving in the academy in comparison to her. However, Rika ''did'' offer to help her with her classwork and invited her to tea, but it was because of her stubborn pride that Satoko rejected these offers. In short, Satoko paved the way for her own suffering because she did not want Rika to leave her. Yet, Satoko insists that Rika is the one who betrayed her and pushed her into recreating the GroundhogDayLoop where they and all of their friends are repeatedly murdered.
* NotAfraidToDie: Unlike Rika who ''never'' was okay with dying even after hundreds of times, Satoko is ready to commit suicide at the most minor inconvenience to restart the loop.
* PennyAmongDiamonds: {{Deconstructed|Trope}}. Satoko is a CountryMouse girl who enrolls at St. Lucia Academy because her best friend Rika wants to go there. Unlike Rika, however, Satoko can't adapt herself to a private school meant for rich and prim ladies. The stiff environment causes her to get behind in her studies because she's too bored to even pay attention to the lessons, gets sent to detention for pulling a prank on Rika and her GirlPosse, and everyone except Rika looks down on [[LowerClassLout her loud and bad-mannered personality]].
* PleaseDontLeaveMe: In the manga version of Tataridamashi, a Level 5 Ooishi arrives at the Watanagashi festival to kill Rika. Just as their friends are being killed, Satoko begs Keiichi to stay with her and be her new Nii-Nii. Keiichi still goes to protect Rika, leaving Satoko disappointed and frustrated at feeling Keiichi chose Rika over her.
* PoorCommunicationKills: {{Downplayed|Trope}}. Satoko might have been able to stay friends with Rika at St. Lucia the first time around if she had properly talked with Rika about why she doesn't feel at ease in such an strict place instead of only complaining about how she hated studying as well as assuming Rika ratted her out after her prank and stop communication altogether. However, the second loop proves that even if Satoko ''does'' speak with Rika about why she doesn't want to go to St. Lucia with her and Rika promises to stay her friend, they run into pretty much the exact same problems because Satoko ''still'' refuses Rika's help when she falls behind in her studies and resents Rika for hanging out with her GirlPosse.
* PseudoRomanticFriendship: With Rika. The hugging and hand-holding is even more emphasized between them in ''Gou'' than the original series. There's also the scene where Satoko cuddles with Rika after the latter falls asleep while studying. This takes a dark turn when Satoko develops a possessiveness towards Rika after Rika starts liking to hang out with rich girls better and it eventually culminates in Satoko going full-on {{Yandere}} on Rika by dragging her into a gruesome MurderSuicide so she can trap Rika in June 1983 once more, all in order to never feel ignored by Rika ever again.
* RebelliousSpirit: Much like Shion in fact, Satoko has no desire to conform to how St. Lucia expects it's students to present themselves, not even bothering to tuck her shirt in. Understandable given that she's only here because of Rika, but it unfortunately only results in her peers mocking her behind her back.
* RedEyesTakeWarning: Her eyes turn red when she's exposed as the other looper by Rika.
* TheResenter: She becomes envious and resentful of Rika due to her capability of blending in seamlessly with the student body whereas her grades were failing forcing her to take remedial classes.
* ResurrectionDeathLoop: Like Rika, Satoko can end and restart a loop whenever she dies. Unlike Rika, she's keeping the loop going on purpose to avoid arriving to the future where she isn't friends with Rika anymore.
* RippleEffectProofMemory: Her EnigmaticEmpoweringEntity gives her the power of MentalTimeTravel upon death and Satoko can keep her full memories of all the loops.
* SanitySlippage: Even though Irie claimed the Satoko's Hinamizawa Syndrome was cured a year after ''Matsuribayashi-hen'', Satoko's mental state once again deteriorates after arriving at St. Lucia Academy because of all the stress of the classes and pressure to get good grades. While it's unclear whether she redeveloped the syndrome, after rewinding time and failing to prevent the exact same situation with Rika at St. Lucia to repeat, Satoko completely goes insane and starts abusing her MentalTimeTravel powers to create a future where Rika is only hers.
* SerialKiller: With her looping powers, Satoko is either directly responsible for the deaths of Rika and the club, or she influenced them. Rinse and repeat several times for the sole purpose of breaking Rika.
* SlasherSmile: Once she's exposed as the BigBad of ''Gou'', she sports an evil grin as she pulls out a gun. Sotou takes this trope up to eleven.
* StepfordSmiler: When it's time for one last club meeting with Mion and the others, she's able to convincingly act like her usual peppy and haughty trapmaster self. Once everyone else parts with her so she can take a walk around the village however, it quickly crumbles to reveal just how exhausted and depressed she really is.
* TeensAreMonsters: Teenage Satoko becomes a possessive, murderous {{Yandere}} for Rika and the BigBad of ''Gou'' who trapped herself and her friends in the gruesome GroundhogDayLoop of June 1983 all over again.
* TimeLoopFatigue: In the ''Meguri'' manga, she goes through many loops where she tries and fails over and over again to reach a scenario where neither Rika or Satoshi die. After countless failures, Satoko looks dead inside.
* TimeTravelForFunAndProfit: After a mysterious purple-haired woman gives her MentalTimeTravel powers, Satoko spends her first loop trying to sabotage Rika's attempts to study so she can't go to St. Lucia Academy. When that doesn't work and she sees Rika making new friends again, Satoko chooses to exploit her new powers by killing herself and her friends over and over to create a GroundhogDayLoop where none of them, especially Rika, will ever leave Hinamizawa and she can play with them forever. At one point, Satoko starts abusing her looping powers for something as trivial as winning a memory card game.
* TomboyAndGirlyGirl: The Tomboy to Rika's Girly Girl, same as in the original series, but it gets PlayedForDrama in ''Gou''. Satoko is still the same mischievous girl who loves traps as when they were kids, but Rika develops an interest for a more sophisticated lifestyle which attracts her attention to St. Lucia Academy. When they arrive at the prestigious school, Rika fits right in with her ProperLady behavior and soon gains the admiration of several other girls. On the other hand, Satoko's energetic and abrasive personality makes her come across as unrefined and this makes other girls look down on her.
* TookALevelInJerkass: Satoko acted like a BrattyHalfPint a lot in the original series, but she was a JerkWithAHeartOfGold at worst and was truly loyal to her TrueCompanions who she cared for as her family. In ''Gou'', Satoko grows up to be a very self-centered, disrespectful, and prideful teenager who eventually becomes possessive, manipulative, and ''shockingly'' abusive towards her best friend Rika, going as far as to recreate the hellish GroundhogDayLoop where Rika is gruesomely murdered over and over to get back at Rika for letting their friendship fall apart in the future even though Satoko had an even bigger hand in that because Satoko pushed away from Rika the moment Rika made new friends at St. Lucia Academy.
* TouchedByVorlons: She enters Saiguden, touches a weird horn that fell from Oyashiro-sama's statue, and is transported to a strange dimension where she meets a woman dressed like a {{Miko}} and wearing a horn-like device. This mysterious woman then grants Satoko with the ability to rewind time by dying so she can create a world where Rika will stay at Hinamizawa with her forever.
* TroubledAbuser: Satoko was ostracized by everyone in the village because her parents supported the dam project and her parents died in a tragic accident caused by Satoko's Hinamizawa Syndrome making her hallucinate they were going to kill her so she pushed them down a cliff. Then she and her older brother are left under the custody of their uncle and aunt who proceed to abuse and neglect the siblings for a year. Satoshi then goes missing on Satoko's birthday, after murdering their aunt and Satoko believes he abandoned her. After she had no relatives left, Rika became like Satoko's only family once they started living together. Feeling neglected in favor of Rika's new friends at St. Lucia gradually causes Satoko to lose her mind. Once she receives MentalTimeTravel powers from a magical being and she understands that Rika can't be talked out of going to St. Lucia, Satoko opts to cruelly abuse Rika physically, emotionally, and psychologically by trapping her in a new, even worse GroundhogDayLoop hell where Satoko'll have Rika be brutally tortured and murdered until Rika's mind and spirit are so broken that she'll never even think about leaving Hinamizawa again.
* UsedToBeASweetKid: The CheerfulChild who loved traps from the original series grew up to be an insane and vicious SerialKiller with MentalTimeTravel powers that she abuses to torture and murder her ex-best friend for the simple fact that Satoko hated seeing Rika becoming friends with some rich girls at St. Lucia Academy and felt betrayed when Rika let Satoko keep her distance after getting behind in her studies.
* VilerNewVillain: In the original series, Shion and Miyo Takano were maniacs who had tragic pasts which led them to becoming murderers. On the other hand, Satoko in ''Gou'' behaves like a crazed psychopath who is willing to put her best friend through the same hell she finally escaped from after 100 years, all because she hated to see Rika in a better social and academic position than her at high school.
* VillainProtagonist: She's the POV character of the final arc of ''Gou'', ''Satokowashi-hen'', that tells the story of Satoko's StartOfDarkness that eventually drove her to recreate the infernal GroundhogDayLoop of June 1983 out of an extremely selfish wish to never become estranged from any of her friends, especially Rika, as it happened in the future. The next season, ''Sotsu'', is all about showing from her POV how she injected her friends and caused the death of many people just to torment Rika.
* WalkingSpoiler: That there's another looper besides Rika and that looper is no other than Satoko are the biggest revelations of ''Gou''.
* WeUsedToBeFriends: After she and Rika arrive at St. Lucia Academy, they gradually stop being as close as they were in Hinamizawa because Rika gets popular at the school while Satoko's behavior alienates her from everyone as she doesn't even want to get along with the refined girls at the school like Rika does. Due to Satoko pulling a prank on Rika and her GirlPosse, Satoko is sent to a detention cell and thinks Rika ratted her out (it was actually one of Rika's GirlPosse) and this makes them drift away even more to the point they barely see and talk to each other until their visit to Hinamizawa.
* WithGreatPowerComesGreatInsanity: While she was bitter and unhappy at St. Lucia Academy, she was still mentally stable. After Eua grants her MentalTimeTravel powers, Satoko's descent into madness really starts and drastically escalates as she repeatedly kills herself and her friends to prevent the future where Rika goes to St. Lucia from happening.
* WomanScorned: {{Exaggerated|Trope}} in the most extreme way possible. Rika promises Satoko to continue being her best friend and be there for her no matter what. Then Rika makes new female friends at St. Lucia Academy and has fun at tea parties with them while Satoko is hating absolutely everything about the school and calls Rika a traitor despite her being the one who pushed away from Rika and refused to get involved in her new circle of friends. This causes Satoko to snap and starts abusing her MentalTimeTravel powers by pulling a MurderSuicide with Rika and recreating the GroundhogDayLoop where Rika was trapped for 100 years while she makes Rika get murdered in even more horrifyingly brutal ways than before so that Rika's spirit is utterly destroyed and never again thinks about leaving Hinamizawa, the only place where Satoko can have Rika all to herself.
* WoobieDestroyerOfWorlds: Her fall into evil was an amalgamation of many misfortunes: already having a bad upbringing due to her living with an abusive uncle after unwittingly killing her parents and her older brother disappearing, Satoko also developed the Hinamizawa Syndrome as well as dependency and abandonment issues. But when Rika told her of her dream to attend St. Lucia Academy, Satoko opts to go with her because she [[HatesBeingAlone did not want to be left alone]]. Unfortunately while she successfully enrolls in the school, she is badmouthed by the other girls due to her inability to conform; her abandonment issues worsen leading her to psychotically believe that Rika had betrayed the promise that she made with her; she becomes overly depressed at the stress of taking remedial classes, and she is forcibly given looping powers against her will. When reliving June 1983, likely the start of the unraveling of her sanity, she does try to prevent her BadFuture from happening only to relent when Rika promises to help her when they went to the school. As the events from before play out again, Satoko becomes suicidal and selects to take Rika with her to restart the loop.
* WoundedGazelleGambit: In ''Tataridamashi-hen'', Satoko has a FreakOut when Keiichi tried to pet her head like in ''Tatarigoroshi-hen'', and everyone takes this as confirmation that Teppei is abusing Satoko. She actually faked it. In ''Sotsu'', she's a manipulative monster, tricking Teppei into thinking the villagers beat her up while simultaneously making her classmates think Teppei is beating her.
* {{Yandere}}: Satoko's possessive "love" for her best friend Rika eventually becomes destructively toxic and drives her to go completely insane and restart the GroundhogDayLoop where she and her friends are brutally murdered over and over again in June 1983, all because Satoko can't think of any other way to prevent the future where Rika goes to St. Lucia Academy and starts hanging out with other girls.
* YouCantGoHomeAgain: After meeting with her friends while on break from St. Lucia's and having a reunion of their games club, Satoko's subsequent walk around Hinamizawa seems to only emphasize how the village she grew up in is changing rapidly, to the point where it feels like it's almost actively trying to erase the remnants of her childhood. She discovers that the old schoolhouse where she and the rest of the club spent so many happy hours is slated to be torn down due to its age, the house she and Rika used to live in collapsed in a massive snowstorm the previous winter, and with all of her friends other than Rika now attending university in Okinomiya, she has basically no personal connections in the village anymore.

[[quoteright:300:https://static.tvtropes.org/pmwiki/pub/images/eua_mei_11.png]]

A mysterious supernatural entity resembling Hanyuu who appears before Satoko in the Saiguden. Previously nameless, Satoko inadvertently gives her the nickname Eua in Episode 23.
----
* AmbiguouslyRelated: She ''seems'' to be Featherine Augustus Aurora from ''VisualNovel/UminekoWhenTheyCry'', even making references to ''Umineko'', but has a different voice actress, and is confirmed by WordOfGod to not be the exact same character (which would explain why their voice actresses are also different). What the exact relationship between the two remains unknown. Episode 15 of ''Sotsu'' heavily hints that she is at most set to one day ''become'' Featherine, but due to the ambiguity, it can also be implied that they are two different beings.
* AntiquatedLinguistics: Her speech patterns in Japanese are very antiquated.
* ArchEnemy: To Hanyuu; they had apparently known each other for a long time despite Eua never appearing in the main series.
* CheshireCatGrin: The EvolvingCredits of the OP after her reveal shows her making a wide, creepy grin at the audience.
* TheCorrupter: She endorses Satoko's descent into madness and evil with the powers she gave her, never getting tired of singing Satoko's praises for entertaining her with her plans to ruin Rika's life.
* CurtainsMatchTheWindow: She has purple hair and eyes.
* DealWithTheDevil: Subverted; she presents Satoko with her looping abilities after informing her that she knew about her wish. However, Satoko rejects the offer and tries to escape, leading to her forcing Satoko to take them and saying that Satoko entertaining her would be payment enough. However, once the events play out the same way, Satoko happily takes advantage of her powers.
* DiabolusExMachina: Her entire existence in ''Gou'' is for the sole purpose of [[HappyEndingOverride completely undoing the happy ending]] of ''Matsuribayashi-hen'' by appearing out of nowhere in front of Satoko, the only person who was unsatisfied in said world's future, and giving Satoko magical MentalTimeTravel powers so Satoko can abuse them and once again trap herself along all of her friends in the horrifying GroundhogDayLoop of June 1983 where they're all brutally murdered endlessly, all for the sake of Satoko's own selfish happiness and her JackassGenie's amusement.
* EnemyWithout: {{Inverted|Trope}}. Eua refers to Hanyuu as being "part of her" and refers to herself as "the original", it's heavily implied that Eua is a Witch incarnation of Hainiryūn Ieasomūru Jieda, the original Oyashiro-Sama and the person Hanyuu was in life prior to becoming the child-like ghost she is now, making Eua essentially the AnthropomorphicPersonification of the "demon goddess" Oyashiro-Sama legend that formed around that person. Tellingly, she'd been killed by her daughter with the very same weapon that Hanyuu uses to defeat Eua.
* EnigmaticEmpoweringEntity: She's a mysterious supernatural being with magical powers even more powerful that Hanyuu's and randomly gives Satoko MentalTimeTravel powers seemingly on a whim.
* EvilCounterpart: To Hanyuu. Hanyuu placed Rika in the loops largely because she reminded her of the daughter she had in life and wanted to prolong the time she could spend with Rika for as long as possible whereas this new godlike entity takes an interest in Satoko on a whim (while implying she knows her as someone else from another place and time) and grants her the power of rewinding time for her own amusement. While Hanyuu was a benevolent entity, Eua is utterly malevolent as she seems to have chosen Satoko because she predicted the catastrophic results of giving Satoko the power to loop endlessly by killing herself and her friends over and over.
* EvilLaugh: Whenever she's particularly entertained by whatever she watches happening, which always tend to be horrible things.
* ExcessiveEvilEyeshadow: She wears purple eyeshadow and acts as the GreaterScopeVillain responsible for giving Satoko the power to rewind time as well as an EvilCounterpart to Hanyuu. Funnily enough, this trait comes and goes depending on the scene.
* {{Expy}}: Her character design and manner of speech are the same as those of Featherine Augustus Aurora from ''VisualNovel/UminekoWhenTheyCry'', a similarly horned PhysicalGoddess who does things because [[VillainsLoveEntertainment she wants entertainment]]. [[https://07th-expansion.fandom.com/wiki/Higurashi_Gou_SP_Live_Talk An interview confirms that the similarities are intentional]].
* FangsAreEvil: Has noticeable fangs like Rika when her mouth's open.
* FountainOfYouth: When defeated, she reverts to her child form before being banished.
* GracefulLoser: After losing to Hanyuu's miracle slice, she decides to leave, finally ending the loops once and for all.
* GreaterScopeVillain: While Satoko is the BigBad causing the infernal GroundhogDayLoop to have Rika all to herself, she wouldn't have never been able to do that if she hasn't met this mysterious woman who could give her magical MentalTimeTravel powers for the hell of it and actively sought to [[TheCorrupter corrupt]] Satoko into a Witch so that she may entertain her forever.
* HimeCut: Complementing her {{Miko}} attire, she has straight full bangs, cheek-length sidelocks, and long straight hair.
* IGaveMyWord: Tells Hanyuu that she'll only stop her own goals and leave if she can provide a miracle. When Hanyuu manages to slice a bit of her horn and reverts her back to her child-like form in the finale for ''Sotsu'', she keeps her word and leaves Hanyuu's world alone. Though whether or not she actually means it is unclear.
* JackassGenie: She appears before Satoko to grant her wish of "doing everything all over again" and have her relationship with Rika back to the way it was before they went to St. Lucia Academy by giving her the travel to rewind time with her own death. However, Satoko discovers that she can't talk Rika out of going to St. Lucia Academy and their friendship is fated to become estranged because Satoko refuses to adjust herself to Rika's beloved lifestyle in the school. So, Satoko decides to abuse the powers her godlike genie gave her by killing herself and murdering Rika until Rika's mind is so broken that she won't ever think of leaving Hinamizawa and being apart from Satoko ever again. All while the one who gave Satoko her powers sneers at the gruesome show she's watching, akin to what the opening lyrics say. She is also quick to abuse Satoko out of amusement as well when in one loop where Satoko's plan of making Rika suffer [[GoneHorriblyRight works too well]], decides to break her mind in front of her friends. All the while calling the girl a witch and laughing at her pain in the process, leading to that loop's Satoko being killed by Satoko herself, who takes control from then on.
* KarmaHoudini: Similar to Miyo in other entries and Witch Satoko in this series, she gets away with her actions involving the loops and repeated deaths of Rika and Satoko, as well as brutalizing and nearly killing Hanyuu by the end of ''Sotsu''. The worst that happens to her is that Hanyuu cuts off a small part of her horn and reverts back to her child-sized form before departing. Something she herself promised to do had Hanyuu promised to perform a miracle, and it's left ambigious as to if she'll actually honor it in the long run.
* KickTheDog: Loves to do this at Rika's expense. She also kidnapped Hanyuu and has her trapped in a fragment. She also forces Hanyuu [[ForcedToWatch to watch Satoko kill everyone over and over again in multiple loops]] when the two meet again and mocks Hanyuu's inability to do anything.
* LineOfSightName: In Episode 23, she allows Satoko to give her a name. Satoko stutters while thinking out loud ("Um... eh... ooh... ah...") and she takes it as an answer, declaring she is now named "Eua".
* MarkOfTheSupernatural: Like Hanyuu, she's a supernatural being with purple hair and eyes.
* {{Miko}}: Like Hanyuu, she's dressed like a Japanese shrine maiden.
* MythologyGag: In her first meeting with Satoko, she calls her Vier, Mitsuyo, and Anomalous Spinal Cord Specimen [=LD3105=]. These names are all references to [=Ryukishi07=]'s work ''VisualNovel/CiconiaWhenTheyCry'' and its character Vier Dressing who [[ReusedCharacterDesign resembles Takano]] so this woman must have [[MistakenIdentity mistaken Satoko for Vier]] because Satoko is also a blonde. [[spoiler: Though considering the ''When They Cry'' universe's relationship with the multiverse, anything is possible.]]
* NeverGivenAName: This character initially is not given a name or form of identification; even in the credits, only her voice actor is listed. When Satoko finally asks her for her name, the woman says she doesn't have one because she only became self-aware when Satoko accidentally awakened her. She then asks Satoko for a name and settles to call herself "Eua" from the sounds of Satoko's mumbling.
* OnlyKnownByTheirNickname: Post-episode 23, she is referred to as Eua, yet insists that she has no real name with Satoko's nickname only used for convenience.
* OutsideContextProblem: As far as the original series goes, Hanyu was the only godlike spirit who could grant time-looping powers to a human. Come ''Gou'' and Satoko runs into this mysterious woman who gives her time-looping powers on a whim so Satoko can undo ''Matsuribayashi-hen'''s happy ending and restart the bloody GroundhogDayLoop all over again just because she hates a future where Rika isn't her best friend anymore.
* ReusedCharacterDesign: She looks identical to Featherine Augustus Aurora from [=Ryukishi07=]'s other work ''VisualNovel/UminekoWhenTheyCry'', with the only major differences being she wears a shrine maiden outfit rather than a PimpedOutDress and her horns fork downward rather than going horseshoe-shaped around her head. Many viewers even assumed she ''[[{{Transplant}} was]]'' Featherine when she first appeared. However, an interview with the creator confirms they shouldn't be considered the same character in this context.
* {{Sadist}}: Eua was taking immense sadistic glee at [[ForcedToWatch forcing Hanyuu to watch]] as Satoko butchered Rika and the others.
* SatanicArchetype: Grants Satoko the power to loop through fragments in return for her entertaining her. She is also the main reason as to why Satoko's mental illness worsened, further sending her down a dark path. She also has "horns" on the back of her head, although they're actually a device floating around her head.
* SlouchOfVillainy: While Satoko keeps creating new fragments with her suicides, Eua slouches in her chair as she enjoys the show.
* TheSociopath: Manipulative as befitting a dealmaker. She is chatty and gives off a flair of allure, but it is all part of the deceit. And she gives Satoko powers out of boredom.
* SpellMyNameWithAnS: Since her given nickname is transplanted from Satoko's "err" sounds, it can either be pronounced as "Eua" or "Uhmera".
* VillainsLoveEntertainment: The only payment that she requested Satoko for giving her MentalTimeTravel powers is that Satoko creates an entertaining show for her.
* WalkingSpoiler: Like Looper Satoko, her existence in ''Gou'' is one of the biggest revelations that gives way to the answers of why the GroundhogDayLoop restarted.
* WeMeetAgain: Subverted. She claims that she and Satoko have known each other for a long time, calling her by different names such as [[VisualNovel/CiconiaWhenTheyCry "Vier"]] or "Mitsuyo", but Satoko has no idea what she’s talking about. Played straighter when she meets up with Hanyuu again in the 12th episode, as Hanyuu does recognize her as well.

[[folder:The Witch (spoilers)]]
!!Witch Satoko
!!!Voiced by: Creator/MikaKanai (JP)

The witch version of Satoko that was inadvertently created due to Satoko's looping.
----
* CanonCharacterAllAlong: [[spoiler: Creator/Ryukishi07's "Another End" web novella finally confirms her to be none other than [[UminekoNoNakuKoroNi Lambdadelta.]] ]]
* EnemyWithin: Satoko starts hesitating about shooting Teppei and tries to [[MyGodWhatHaveIDone give up on the plan]]. Her Witch self takes over and finishes the job.
* EvilCounterpart: To Frederica Bernkastel. Frederica was an amalgalation of all the Rika's who didn't make it past June 1983, she also possessed Rika in each fragment to try and succeed. While Witch Satoko intends to keep Rika in Hinamizawa. Not to mention the both of them possibly being the Witch Bernkastel and Lambdadelta respectively as well.
* KarmaHoudini: In the final episode, Witch Satoko simply grows bored and gives up on living in Hinamizawa once she and Rika have come to an agreement that makes it clear she can't keep Rika there (and that Satoko doesn't have to go with her to St. Lucia's either), so she relinquishes Satoko's humanity as she moves on to seek out Rika again on the higher plane. This is well after a beatdown from Rika that, thanks to Hanyu's miracle erasing all prior realities, is more like a slap on the wrist.
* KickTheDog: A sign of how far off the deep end is that she easily ups her vileness within minutes of getting control. She lulls and nearly beats Keiichi to death for no real reason other than he was an easy target.
* LackOfEmpathy: She openly rejects the "fake" Satoko because of her emotional drive.
* TheSociopath: Ticks nearly all the boxes: she is manipulative when quietly pulling the strings; she has a disturbing lack of remorse due to her belief that her actions were meaningless due to her ability to loop. The whole reason as to why she restarted the cycle was because she felt personally wronged by Rika and tries to force her own happiness onto her whilst not understanding the implications of it. Whenever she has second thoughts to what she's doing, she falters back to NeverMyFault mentality by blaming Rika for her own actions.
* SplitPersonalityTakeover: The current Satoko has a sudden BattleInTheCenterOfTheMind with Satoko who doesn't want to hurt anyone no more. One guess who won.
* YouHaveOutlivedYourUsefulness: She ends up killing Teppei when he no longer fits the narrative of her having a horribly abusive uncle, and kills her non-sociopathic side when she attempts to prevent this very murder.

----

* VilerNewVillain: In the original series, Shion and Miyo Takano were murderers who had tragic pasts which led them to becoming murderers. On the other hand, Satoko in ''Gou'' behaves like a crazed psychopath who is willing to put her best friend through the same hell she finally escaped from after 100 years, all because she hated to see Rika in a better social and academic position than her at high school.

* VilerNewVillain: In the original series, Shion and Takano were {{Anti Villain}}s with very tragic motivations that drove them to murder people, but they do come to regret their crimes and deep down wished to be stopped. On the other hand, Satoko in ''Gou'' behaves like a crazed psychopath who is willing to put her best friend through the same hell she finally escaped from after 100 years, all because she hated to see Rika in a better social and academic position than her at high school.

* SupportingProtagonist: He's the main POV character of ''Yoigoshi-hen'', but the true protagonist and hero of the story is the older Mion.

* BoobsOfSteel: As a teenager, Satoko's boobs size rivals with Mion, Shion, and Takano's. However, being a villain makes her more dangerous than all three combined.

* PeekABangs: Her hair [[ExpositoryHairstyleChange had this style in middle school]], which got her the nickname "ZashikiWarashi."

* BusCrash: In the Silhouette Arc, [[spoiler:he is killed off camera by]] an acquaintance who succumbed to the curse. This happens before Natsumi can even meet him during her part-time job in that arc, allowing the arc to focus more on some of her core insecurities about Akira and the fallout from the [[spoiler:Great Hinamizawa Gas Disaster]] than the Stain-Spreading Arc could.

* {{Keigo}}: She picked up Satoko's overly polite manner of speech.

* {{Keigo}}: He spoke politely at all times, and taught it to Hanyuu so she'd sound more feminine.

* {{Keigo}}: She speaks politely like her parents.

** She likes to present herself as a refined highborn noblewoman, but as soon as she transfers to a school filled with actual high-status girls where her [[{{Keigo}} hyper-polite speech]] doesn't sound out of place, she finds out the hard way that she is way out of her element and hates it.

[[quoteright:160:https://static.tvtropes.org/pmwiki/pub/images/une_kizuna_casual.png]]

[[folder:Nagisa Ozaki]]
!!Nagisa Ozaki
!!!Voiced by: Mayako Nigo (JP)
[[quoteright:160:https://static.tvtropes.org/pmwiki/pub/images/ozaki_nagisa.png]]

A childhood friend of Rena's from Ibaraki. She appears in ''Tokihogushi-hen''. She helps with Tomoe's investigation into Rena's case.

* ChildhoodFriends: She was friends with Rena during part of their childhood in Ibaraki.
* HeKnowsTooMuch: Near the end of the ''Tokihogushi-hen'', [[spoiler:Nagisa finds out about Tokyo's plan and she tries to warn Tomoe and Rena, but is knocked unconscious and kidnapped.]]

* PennyAmongDiamonds: {{Deconstructed|Trope}}. Satoko is a CountryMouse girl who enrolls at St. Lucia Academy because her best friend Rika wants to go there. Unlike Rika, however, Satoko can't adapt herself to a private school meant for rich and prim ladies. The stiff environment causes her to get behind in her studies because she's too bored to even pay attention to the lessons, gets sent to detention for pulling a prank on Rika and her GirlPosse, and everyone except Rika looks down on her loud and bad-mannered personality.

* FountainOfYouth: When defeated, she reverts to child form before being banished.

!!!Voiced by: Nana Inoue (JP)

* PsychoLesbian: Satoko has a desire to crush Rika's hopes of breaking the GroundhogDayLoop, developing an increasingly toxic and obsessive relationship with her.

* 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]]. 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, only in Miotsukushi-hen that she managed to do so.

* MeaningfulRename: In Onisarashi-hen's epilogue, Akira actively tries to invoke this trope for Natsumi by marrying her, after which she takes his last name, Toudou. He did this specifically to try to separate her from the Kimiyoshi name and its association with the Three Great Families of Hinamizawa and [[KillEmAll everything that connects to]]. In so doing, he hoped to make it easier for her to move on from [[spoiler:the fact that she killed her family]] and forgive herself.
