History Characters / MierukoChan

* EldritchAbomination: Far and away the most unearthly spirit in the series, residing in a [[EldritchLocation shrine on a mountain invisible to those who couldn't see ghosts]], assisted by a pair of shrine maiden ghosts, and as Miko finds out, [[DealWithTheDevil it answers prayers at a high price]].

* ConsistentClothingStyle: Kyousuke is always seen in a t-shirt with an animal on it, captioned with its name in Romaji.

* FriendlessBackground: Throughout her childhood, Michiru couldn't make friends because her strange behavior caused other kids to think she was creepy. Her sister You limited her social interaction as much as she could, thinking that she was protecting her from being hurt.

* LoonWithAHeartOfGold: Michiru is [[EmotionlessGirl stoic to the point of appearing emotionless]] and her stalkerish habits, such as her habit of breaking into the houses of the people she likes at night, make it look like she isn't right in the head. However, she's actually a very kind and caring person at heart. Unfortunately, for most of her life, people avoided her and shunned her because her weird behavior made her creepy to others. She starts heading towards becoming a {{Yandere}} when she obsesses over her new friend Miko, but Hana manages to win Michiru over enough for Michiru to officially become a member of Miko's friend group.

[[caption-width-right:350:[[labelnote:Click here to see its true form]] https://static.tvtropes.org/pmwiki/pub/images/0036_021.png[[/labelnote]]]]
A massive spirit that lives in the mountain in a protected shrine. It saves Miko from a hostile ghost by devouring it.

* AnimalisticAbomination: It looks like a giant kitsune-like creature with a LampreyMouth and horns. Its true form is even worse, a human-fox ''thing'' with a permanent rictus grin and jingle bells for eyes.
* DealWithTheDevil: Miko's innocent prayer at the shrine results in her making one with it on accident.
* DeityOfHumanOrigin: As Mitsue puts it, it is only known as a god by the locals, but it is in no way divine and is extremely dangerous. It ultimately turns out to be a shrine maiden who was ritually sacrificed to be transformed into a god.
* DeusExMachina: Shows up out of nowhere to devour a spirit that was terrorizing Miko and Hana. It then continues to send its shrine maidens to protect her from any spirits that try to harm her. It is later revealed that Miko unknowingly [[DealWithTheDevil made a deal with it]].

* ExoticEyeDesigns: Has jingle bells for eyes.
* GodOfGood: Helps Miko by protecting her from spirits, killing the one that Miko and Hana had brought to its shrine and then sending its shrine maiden ghosts to destroy any ghosts that attack her to her up to three times. Turns out to be a subversion, as Miko actually made a deal with it unintentionally, where it would protect her from hostile ghosts thrice before she has to pay up. The only words when it asks for its repayment that Miko can make out are "sacrifice of flesh and blood".
* MultiArmedAndDangerous: Has rows and rows of humanlike arms holding innumerable bells in its true form. For extra creepiness factor it also possesses at least one arm inside its mouth.
* OneWingedAngel: After it tries to devour Miko, the god sheds its skin to reveal a true form that looks so horrific that the usually deadpan Miko drops to her knees in absolute terror.
* SoulJar: Its human self's skull, sealed inside its shrine. Once Miko accidentally destroys it, it promptly reverts from a fox monster back into a shrine maiden and starts to move on.
* TearsOfJoy: She cries when she's finally allowed to pass on from the world of the living, no longer bound to the shrine.
* VillainousRescue: It kills off the river-dwelling ghost that had been trying to kill Hana, as she was the payment for Miko's unwitting DealWithTheDevil.
* WasOnceAMan: Originally a shrine maiden who was strongly implied to be the subject of a HumanSacrifice ritual.

A man who comes to adopt a kitten Miko and Hana found. Even though he looks scary, Miko lets him keep the cat because she can see two ghost cats who love him.

* AdorableAbominations: He has two ghost cats that, unlike the vast majority of ghosts seenin the series, are positively adorable and barely look any different from their living counterparts. It's suggested that they were previous cats of his whose love for him tethered them to him in that form. The same goes for his late wife, who is one of the few humanoid ghosts to not have any grotesque elements to her at all.
* BaldHeadOfToughness: {{Subverted|Trope}}. He's a bald guy with a FaceOfAThug, causing people to think he could kill somebody. The truth is he's a KindheartedCatLover who would never hurt a fly.

[[folder:You Ichijou]]
!!You Ichijou

Michiru's controlling older sister and manager.

* NoGoodDeedGoesUnpunished: From her perspective she does nothing but try to help the people she likes, and they always end up hating her for it. With her knowing that she did something to drive them away, but not able to understand where she went wrong.

* ParentsAsPeople: You truly cares about Michiru, but she had to take up the responsibility of raising a young child when she was just a teenager herself. Michiru's peculiar behavior also made it especially hard for You to handle her. Despite her best intentions, You has caused a lot of stress for Michiru by trying to isolate her from her peers, as she couldn't think of other ways to protect her sister from becoming a social outcast due to other kids finding her weird and creepy. Whenever Michiru tried to help someone and it backfired when she ended up looking like a creep, You only told her that she was a good girl instead of trying to explain to her why it's wrong to break into other people's houses at night. When Michiru starts exhibiting [[{{Yandere}} possessive behavior]] towards Miko, You tries to get Michiru out of the school, being terrified that Michiru could end up hurting Miko's other friends and become hated as a result. After she sees Michiru has finally found friends who accept her for who she is, You stops acting overprotective and allows Michiru to socialize more.

** [[GreenEyedMonster Anything that looks like it might take Miko away from her]]. She's starts out mostly annoyed and somewhat hostile toward Hana for interjecting into moments where she feels connected to Miko, such as when Hana mentions that she thinks her Lambda Rabbit keychain is cuter than the Meme-chan keychan that Michiru and Miko like, but the realization that Hana actually already has the sort of extremely close relationship with Miko that she herself wants provokes a violent response from her spirit on similar to their reaction to You. She loses this after befriending Hana as well, however.

* PinocchioNose: Her eyes dart away whenever she lies to someone. Ironically, Miko actually can't see this obvious tell since Michuru's spirit covers her entire head.

* BerserkButton: In general, she seems to get very upset over small things, which Miko can tell due to her [[EmpathyPet octopus spirit's]] tentacles acting like they will stab someone, such as when they seem to be about to stab Hana when the latter mentions her Lambda Rabbit keychain is cuter than the Meme-chan keychain that Michiru and Miko like.

** She seemingly possesses an near unnatural HyperAwareness of others spying on her, immediately knowing that Yuria is watching her off to the side in a bathroom stall, or that Miko has just taken a picture of her mid basketball shot.

* PinocchioNose: Her eyes dart away whenever she lies to someone.

* AbhorrentAdmirer: Michiru is all but outright stated to be madly in love with Miko, or at the very least wants to be close with her. Although most people see Michiru as a pretty girl, all Miko can see is a terrifying tentacle monster whose odd mannerisms only makes her scarier towards Miko.

** At first, it's heavily suggested that Michuru has a history eventually becoming violent towards others, even stabbing another student with a pen to drive them away from the target of her affection. However, it's revealed that she's never deliberately hurt anyone in the past and the aforementioned student ''was'' the target of her affection. Michuru had gotten obsessed with trying to find the girl's favorite missing pen in an attempt to win her over and accidentally cut the girl's palm when she tried to pull Michuru away from rooting around other students' desks.
** Michuru's octopus like spirit is very ominous in appearance but turns out to be an entirely benign NatureSpirit that's trying to protect her.

Michuru had gotten obsessed with trying to find the girl's favorite missing pen in an attempt to win her over and accidentally cut the girl's palm when she tried to pull Michuru away from rooting around other student's desks.

* {{Cthulhumanoid}}: From Miko's perspective, she looks like a girl with a large tentacled and eyeless thing for a head, even in photographs.

* GoodIsNotNice: [[[spoiler:Despite Zen ultimately being innocent of the string of cat killings and becoming much more sociable after his mother's spirit is banished, he abducts the actual cat killer and makes him disappear]].

* ClingyJealousGirl: Michiru is ''very'' possessive of Miko and doesn't take kindly to anybody who would steal Miko's attention away from her. In particular, she doesn't like Hana due to her status as Miko's BestFriend.

* DemonicPossession: Romm's theory on Michiru's situation is that she is actually being possessed by a ghost that reacts to Michiru's emotions and that it's Miko's ridiculously strong ability to perceive spirits that causes Miko to be unable to perceive the girl that the monster has bonded to.

* EmpathyPet: This is effectively how the [[HeadPet octopus spirit latched on to her head]] functions in Miko Vision. Its tentacles will writhe and poise themselves to "stab" someone if she gets upset with them, they will reach out for things she wants, like a caterpillar-shaped pastry since she likes caterpillars, and they will gently wrap themselves around Miko while walking together since Michiru likes her.

* FriendlessBackground: Throughout her childhood, Michiru couldn't make friends because her strange behavior caused other kids to think she was creepy. Her sister You limited her social interaction as much as she could, thinking that she was protecting her from being hurt. The few friends she could make ended up being driven away when her violent impulses kicked in and made her hurt someone.

* IJustWantToHaveFriends: All Michiru wants is to have friends, but she always ended up driving people away with her creepy and deranged behavior. It didn't help that her sister You tried to "protect" her by isolating her from her peers. She's very happy to hang out with Miko and her other friends because she finally feels like part of a group.

* ThePenIsMightier: She once stabbed a classmate with a pen. Later on, she tries to do the same with a pencil to Hana, [[spoiler:but Hana calms her down before she can attack her]].

* PsychoLesbian: She takes an almost immediate liking to Miko which quickly becomes a scary obsession.

* {{Yandere}}: After she sees Miko is much closer to Hana than her, Michiru decides she must get Hana out of the picture to have Miko to herself. Miko can see that Michiru's ghost tentacles react ''very'' hostilely towards Hana, but [[ObliviousToLove doesn't get that the cause is Michiru's crazy jealousy over their friendship]].

* ClingyJealousGirl: Subverted. At first, it's made look like You wants Michiru all to herself and doesn't approve of her forming personal relationships outside of her. Turns out the real reason is that You is well aware of Michiru's {{Yandere}} tendencies towards her friends and she's trying to limit Michiru's social interaction because her sister might end up hurting people, as it has happened before.

* MyBelovedSmother: She's Michiru's older sister instead of her mother, but fits perfectly otherwise. She's extremely controlling and clingy towards Michiru, often suffocating her with overbearing attention. When Michiru tries to have a sleepover with Miko, You runs through a storm to pick up her sister and take her home, as she would worry too much if she let Michiru stay the night at a stranger's house. Given [[{{Yandere}} Michiru's somewhat deranged behavior towards her targets of affection]], You's concerns and wish to keep Michiru under her watch 24/7 become a bit more understandable.

* ParentsAsPeople: You truly cares about Michiru, but she had to take up the responsibility of raising a young child when she was just a teenager herself. Michiru's peculiar behavior also made it especially hard for You to handle her. Despite her best intentions, You has caused a lot of stress for Michiru by trying to isolate her from her peers, as she couldn't think of other way to protect her sister from becoming a social outcast due to other kids finding her weird and creepy. Whenever Michiru tried to help someone and it backfired when she ended up looking like a creep, You only told her that she was a good girl instead of trying to explain to her why it's wrong to break into other people's houses at night. Things got worse when Michiru started exhibiting [[{{Yandere}} violently possessive behavior]] towards her friends, driving You to try to get Michiru out of the school the moment she discovers Michiru's obsession with Miko, being terrified that Michiru could end up hurting Miko's other friends like it happened the last time Michiru got possessive over her friends.

* BrokeYourArmPunchingOutCthluhu: It's heavily implied that [[spoiler:him defeating the Fox God has put some sort of curse on him, as afterwards he's shown largely holed up in his own home with a massive amount of magical defenses and wards set up to keep ''something'' out]].

* AllLovingHeroine: Hana is very kind, loving and compassionate, always trying to get along with everyone and make her friends happy. [[spoiler:She even befriends a {{Yandere}} who tried to stab her.]]

* TastesLikeFriendship: Hana became friends with Miko because the latter gave her bread at lunch back in elementary school.

* UnknownRival: She feels jealous of Hana's long-term friendship with Miko and soon starts seeing Hana as her rival for Miko's affection, not that either Miko or Hana notice because they don't even know about Michiru's obsessive infatuation.

* WhiteHairBlackHeart: {{Subverted|Trope}}. She has white hair and she's a creepy stalker with dangerous {{Yandere}} tendencies. However, Michiru isn't actually a bad person, just lonely and socially maladjusted. She starts to get a better as she grows closer to Miko's group.

* ParentsAsPeople: You truly cares about Michiru, but she had to take up the responsibility of raising a young child when she was just a teenager herself. Michiru's peculiar behavior also made it especially hard for You to handle her. Despite her best intentions, You has caused a lot of stress for Michiru by trying to isolate her from her peers, as she couldn't think of other way to protect her sister from becoming a social outcast due to other kids finding her weird and creepy. Whenever Michiru tried to help someone and it backfired when she ended up looking like a creep, You only told her that she was a good girl instead of trying to explain to her why it's wrong to break into other people's houses at night. Things got worse when Michiru started exhibiting [[{{Yandere}} violently possessive behavior]] towards her friends, driving You to try to get Michiru out of the school the moment she discovers Michiru's obsession with Miko, being terrified that Michiru could end up hurting Miko's other friends.

* OrdinaryHighSchoolStudent: Miko was a perfectly normal high school girl until one day she [[ISeeDeadPeople suddenly starts seeing abominable ghosts all around her]]. From then on, she constantly struggles to keep living her life like normal despite the scary things only she sees.

* RightForTheWrongReasons: When she and Hina meet Touno Zen when trying to find someone to adopt a stray cat, she assumes that he's a cat killer based on the evil-looking cat spirits surrounding him and instead gives the cat to the guy with the FaceOfAThug surrounded by more benevolent cat spirits. [[spoiler: She's right that the cat would have been in danger, but more so because of the ghost of Zen's mother who killed every cat he came to own after her death.]]

* StepfordSmiler: [[spoiler:A bit, chapter 53 reveals that at least some of Hana's personality is an act she puts on because she can tell that Miko has changed since her dad died but since Miko won't say anything and Hana doesn't want to push the issue she instead tries to be as cheery around Miko as possible.]]

* AntiHero: [[spoiler:It's eventually revealed that he's NOT a cat killer as you'd initially believe from his initial appearance, and it was actually his abusive mother and that he's actually a selfless and heroic person who got hit by a car to save a kitten. However, it's also shown that he killed an evil man who likes to kill cats for fun without any emotion.]]

* GoodIsNotSoft: [[spoiler:He eventually finds the cat killer who was hunting the cats in his neighborhood. Zen tases the culprit and some time later, the latter is still missing...]]

* ThePenIsMightier: She once stabbed a classmate with a pencil. Later on, she tries to do the same to Hana, [[spoiler:but Hana calms her down before she can attack her]].

* WhiteHairBlackHeart: She has white hair and while not evil per se, she's a creepy stalker who is deserving of a restraining order.

CurbStompCushion: During [[spoiler:Michuru's confrontation with Hana]] a monstrously large spirit related to the similarly enormous one that tried to rip her tentacles from Miko attacks her in revenge. This time, possibly due to the tentacles being distracted with [[spoiler:preparing to attack Hana (as they coil into a spear like limb surrounding the hand that Michuru is [[ThePenIsMightier holding a pencil in]])]], the giant actually manages to cause some damage by successfully ripping some tentacles away. However Michuru's octopus spirit barely acknowledges the assault due to being so focused on [[spoiler:Hana]] and after being supercharged by [[spoiler:Hana's aura]] it swells to such enormous proportions that its spiky tentacles literally take up the entire room, crushing the attacking spirit instantly.

* ClingyJealousGirl: She wants Michiru all to herself and doesn't approve of her forming personal relationships outside of her. Once she discovers Michiru's newfound infatuation with Miko, she tries to get Michiru transferred to another class to separate her from Miko.

* IncestantAdmirer: She has a quite creepy relationship with Michiru where she tries to have constant physical contact with her and even makes her take baths together. Michiru doesn't openly object to any of this, but her true feelings are obvious since the spirit latched on to her head reacts the most hostilely to You.

* MyBelovedSmother: She's Michiru's older sister instead of her mother, but fits perfectly otherwise. She's extremely controlling and clingy towards Michiru, to the point she treats her like her doll instead of a person. When Michiru starts openly defying her to spend more time with Miko, You loses it.

* PromotionToParent: She acts as Michiru's guardian and caretaker due to the loss of their parents.
* {{Yandere}}: When it becomes obvious Michiru prefers to spend more time with Miko over her, You wants to get rid of Miko to monopolize Michiru's attention once more.

* AnimalisticAbomination: It has a large horse-like body with humanoid face and arms.

* DeadAllAlong: Mamoru looks normal compared to the other ghosts, making the audience believe he's still alive until TheReveal that he's dead when Miko gives her pudding as an offering to his butsudan.
* DisappearedDad: Mamoru died at some point before the start of the series, but he still hangs out with his family as a ghost in their house.
* FriendlyGhost: Unlike most ghosts in the series, Mamoru isn't scary at all and simply hangs out at the house with his family as if he was still alive. He speaks to his children like the kind father he is despite his son not being able to see him and his daughter having to pretend to not see him.
* GoodParents: Both are good to their children. Even though Mamoru is a ghost, he still speaks kindly to Miko (he doesn't know she can see him) and goes to send her off along with Touko before Miko goes to school every morning.

* BrutalHonesty: He tells Miko to her face that he thinks she's weird. After he hears Miko speak about freedom [[spoiler:to his evil ghost mother]], Zen takes it as her suggesting him to be more honest.

* LostPetGrievance: [[spoiler:When he was a boy, his mother killed the stray cat that he had taken in as a pet.

Zen's emotionally abusive mother, who now haunts him as a monstrous ghost.

* AbusiveParents: She was emotionally abusive towards Zen, didn't let him have a life outside of schoolwork, and killed the stray cat he secretly took in as a pet.
* BadPeopleAbuseAnimals: She killed a cat Zen brought in one time when he was young, to punish him for keeping secrets from her and doing something that wasn't studying. Her ghost still haunts him, and keeps the dead cats he regrets being unable to save bound to him.
* BerserkButton: She ''hated'' it when Zen didn't share information with her, telling him he was just like his unfaithful father for it.
* ControlFreak: Zen could not have ''anything'' independently of her, to the point she'd yell at children passing by her house to stay away if she thought they were his friends. She still has this attitude as a ghost, bellowing at her son's students not to look at him.
* EducationMama: She forced Zen to study all day and never let him spend any time with other kids. When he got 98 out of 100 on a test, all she did was berate him for not getting a perfect score.
* EeriePaleSkinnedBrunette: As a living human, she had dark hair and her skin was extremely pale, bordering on gray. This made her look creepy even before she became a ghost.
* FamilyEyeResemblance: Zen got his dull, lifeless red eyes from her.
* GhastlyGhost: After dying, she became a horrifying spider-like ghost that continues haunting her son, roaring furiously at anyone who merely ''looks'' at him.
* {{Gonk}}: Downplayed. Her face is thin and elongated, she has dark iris with no pupils and a set of TombstoneTeeth. While she's not exaggeratedly hideous, her looks take a turn for the creepy and unnatural compared to other character designs in the series. It's even worse in the manga, where she's drawn in the same [[UncannyValley uncomfortably detailed]] style as the ghosts ''while she's still alive''.
* HateSink: She's a controlling, emotionally incestuous abuser who made her son's childhood miserable and killed the only pet he ever had. Then she keeps haunting him as a terrifying ghost until Miko makes some shrine spirits forcibly exorcise her.
* IncestSubtext: The odd specificty of the scorn she heaps upon her young son, calling him a promise-breaking malicious liar who betrays the trust of the woman who loves him more than anyone else in the world, certainly suggests she sees Zen as an emotional proxy for her cheating ex-husband.
* MyBelovedSmother: Even in death, she's a deranged ControlFreak out to maliciously maintain a vise-grip on her son's life.
* SpiderPeople: As a ghost, she has spider legs and a spider-like mouth.
* UnnamedParent: We never get to hear her name.
* WalkingSpoiler: Her backstory with Zen reveals he isn't the cat killer Miko thought him to be.

* AntiHero: His motivation is good, but his method is shady. He had mentioned three plans to enter the Shrine which required Hana's aura to break through its barrier. Plan A is to convince Miko to bring Hana along. Plan B is to use stones to absorb some of Hana's aura so that her personal presence is not needed. Shindou remarks that he is very pleased than Plan C was not needed. Whatever it was, it could not have been good.
* BigGood: Being an active ghost hunter who arguably has the strongest psychic abilities among the cast, and has by far the most success of excising hostile spirits. This is best highlighted in the Anthology comic when Romm tends a make an appearance every time a particularly dangerous ghost needs to be taken care of.
* BrutalHonesty: He bluntly tells Miko that his charms won't do much against the Fox God while asking her to keep its attention anyway.
* CatchPhrase: "[This item] is brimming with power!"
* ChronicHeroSyndrome: Surprisingly, Romm took Towako's teachings to help people, both the living and the dead, to heart. The reason why he has such a great interest with the mountain shrine is because [[spoiler: he once heard a girl asking for help, implied to be the spirit of a sacrifice victim who later became the Fox God]].
* CreepyGood: Miko's first impression of Romm is him acting like a creep and a lot of his behavior makes him suspicious. He's ultimately a good guy with heroic intentions, although his methods can be crafty.
* CreepyShadowedUndereyes: He has distinct undereye shadows, making him look a bit creepier than other living characters.
* ExhaustedEyeBags: He has some noticeable bags under his eyes, which are implied to come from the horror he experiences due to being able to see spirits like Miko.
* GoodAllAlong: He takes several actions to help Miko like sending Mitsue the picture of Miko and Hana at the shrine, which allowed Mitsue to save Miko, and giving Miko one of his exorcist stones. However, whether he's a good guy is still questionable for a while. He becomes more suspicious after it's implied he's willing to use his tour group as guinea pigs to test his items on a very dangerous spirit. Mitsue also didn't trust him since she knew he had an ulterior motive for helping Miko get rid of the Shrine God. [[spoiler:At the end of the Shrine arc, it's revealed Romm's ultimate goal was freeing the ghost of the girl that was sacrificed long ago and was left trapped inside the shrine for centuries, waiting for someone to help her.]]
* HidingBehindYourBangs: His right eye is obscured by his hair and he's very shady most of the time, causing Miko and Mitsue to question how much they can trust him.
* JerkassHasAPoint: Mitsue is pissed that Romm brought Miko along, as she's concerned he may use her for selfish reasons. Romm argues that Mitsue's insistence on dealing with the shrine gods on her own while leaving Miko in the dark completely, considering they may come to "collect their debt" at any moment, is not very reassuring.
* MorePoweredProtege: He was Mitsue's disciple when he was younger, but Romm's stronger ability to see spirits made Mitsue feel very unfit to be his mentor.
* NervesOfSteel: He has the same degree of paranormal vision as Miko and has had a lifetime to learn how to keep a cool head in the presence of terrifying ghosts.
* NotSoPhonyPsychic: He performs exorcisms and posts videos of them on Youtube, but most of his audience can't see the ghosts so they think he is a fraud, which isn't helped by him to keep telling them to subscribe and buy his overpriced exorcism gear. But a few people like Yuria and Miko can see the ghosts he's exorcising and know he's the real deal.
* PermaStubble: He has a small amount of facial hair on his chin. It helps to add to his sleazy appearance.
* PetTheDog: He lets Miko keep one of his power stones since he feels she truly needs it and sends Mitsue a picture of the shrine.
* PostModernMagik: Use this liberally compared to everyone else. For example, he uses a smartphone and heavy metal music to repel ghosts. Other than that he's also shown to use the more mundane aspect of this trope, such as using the internet to promote his psychic business.
* PunnyName: His name translates as "Boy Wonder Rom", but it's pronounced the same as his moniker "Syndrome".
* ShamelessSelfPromoter: In his online videos, he keeps telling people to subscribe and buy his exorcism gear.
* SignatureHeadgear: He wears an iconic top hat with buttons sewn on it.

[[folder:Fox God (SPOILER)]]
!!The Fox God
!!!'''Voiced by:''' Masashi Yamane (JP)
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/shrine_god.png]]
[[caption-width-right:350:[[labelnote:Click here to see its true form]] https://static.tvtropes.org/pmwiki/pub/images/0036_021.png[[/labelnote]]]]
A massive spirit that lives in the mountain in a protected shrine. It saves Miko from a hostile ghost by devouring it.
----
* AnimalisticAbomination: It looks like a giant kitsune-like creature with a LampreyMouth and horns. Its true form is even worse, a human-fox ''thing'' with a permanent rictus grin and jingle bells for eyes.
* DealWithTheDevil: Miko's innocent prayer at the shrine results in her making one with it on accident.
* DeityOfHumanOrigin: As Mitsue puts it, it is only known as a god by the locals, but it is in no way divine and is extremely dangerous. It ultimately turns out to be a shrine maiden who was ritually sacrificed to be transformed into a god.
* DeusExMachina: Shows up out of nowhere to devour a spirit that was terrorizing Miko and Hana. It then continues to send its shrine maidens to protect her from any spirits that try to harm her. It is later revealed that Miko unknowingly [[DealWithTheDevil made a deal with it]].
* EldritchAbomination: Far and away the most unearthly spirit in the series, residing in a [[EldritchLocation shrine on a mountain invisible to those who couldn't see ghosts]], assisted by a pair of shrine maiden ghosts, and as Miko finds out, [[DealWithTheDevil it answers prayers at a high price]].
* ExoticEyeDesigns: Has jingle bells for eyes.
* GodOfGood: Helps Miko by protecting her from spirits, killing the one that Miko and Hana had brought to its shrine and then sending its shrine maiden ghosts to destroy any ghosts that attack her to her up to three times. Turns out to be a subversion, as Miko actually made a deal with it unintentionally, where it would protect her from hostile ghosts thrice before she has to pay up. The only words when it asks for its repayment that Miko can make out are "sacrifice of flesh and blood".
* MultiArmedAndDangerous: Has rows and rows of humanlike arms holding innumerable bells in its true form. For extra creepiness factor it also possesses at least one arm inside its mouth.
* OneWingedAngel: After it tries to devour Miko, the god sheds its skin to reveal a true form that looks so horrific that the usually deadpan Miko drops to her knees in absolute terror.
* SoulJar: Its human self's skull, sealed inside its shrine. Once Miko accidentally destroys it, it promptly reverts from a fox monster back into a shrine maiden and starts to move on.
* TearsOfJoy: She cries when she's finally allowed to pass on from the world of the living, no longer bound to the shrine.
* VillainousRescue: It kills off the river-dwelling ghost that had been trying to kill Hana, as she was the payment for Miko's unwitting DealWithTheDevil.
* WasOnceAMan: Originally a shrine maiden who was strongly implied to be the subject of a HumanSacrifice ritual.

[[folder:Oka Towako]]
!!Oka Towako
Mitsue's mentor and Shindou's mother figure. A spiritualist who starred in her own occult television show, Towako parleyed some of that income into supporting her orphanage which catered to children with spiritual powers.
----
* AssKickingPose: Does the same pose after a successful exorcism as part of her television show with her right palm held up and her left hand in a fist with two fingers pointing to the right. This is how Mitsue and Shindou recognize her after she has been [[spoiler:transformed into a servant of the Fox God]].
* BigDamnHeroes: Intervenes when Mitsue and Shindou fall afoul of the [[spoiler:Fox God]].
* CoolOldLady: Was a caring parental figure, active exorcist and media personality deep into old age.
* EyeMotifs: As part of her television costume. Mitsue presumably has the same patterns on her clothing as a tribute to Towako.
* GoOutWithASmile: [[spoiler:After the Fox God is defeated and the soul is the sacrificed girl is freed, Towako's soul passes on with a smile.]]
* HeroicSacrifice: Grabs the [[spoiler:Fox God's]] bell meant for Shindou.
* MistreatmentInducedBetrayal: Forcing her to attack [[spoiler:Mitsue and Shindou]] caused her to turn on the [[spoiler:Fox God]] and attack her fellows.
* NotSoPhonyPsychic: Her television show was mostly Towako going around exorcising ghosts. While she admitted that some of those televised cases were actually fake, she did indeed perform exorcisms for many people in need. Her being a media personality might have influenced Shindou into doing his own webstreaming channel.
* MamaBear: Goes out in full regalia to confront the [[spoiler:Fox God]] who was trying to seize Shindou.
* MentorOccupationalHazard: Presumably dies to protect Shindou from the [[spoiler:Fox God]].
* OrphanageOfLove: Used to run one where both Mitsue and Shindou were raised. It specifically cared for children with spiritual powers since others could not perceive the ghosts these children were reacting to.
* ParentalSubstitute: A mother figure to Shindou and to a lesser extent Mitsue.
* PosthumousCharacter: Died when Shindou was still a kid, [[spoiler:though her spirit still lingers around as one of the servants of the Fox God]].
* ReforgedIntoAMinion: In the current day, she is one of the two servants of the [[spoiler:Fox God]].
* TragicKeepsake: Her robe which is in Mitsue's keeping.

[[folder:Michiru Ichijou]]
!!Michiru Ichijou
!!!'''Voiced by:''' Creator/SaoriHayami (Kadokawa PV)
[[quoteright:275:https://static.tvtropes.org/pmwiki/pub/images/michiru_ichijou_human.png]]
[[caption-width-right:275:[[labelnote:Click here to see the spirit attached to her]] https://static.tvtropes.org/pmwiki/pub/images/ichijou_ghost.png[[/labelnote]]]]
A magazine model who transfers into Miko's class. Despite being human, Miko can only see her as a monster with an octopus for a head. Miko is able to tell her emotions and thoughts through the movements of her tentacles, which sparks Michiru's interest in getting close to Miko.
----

[[folder:You Ichijou]]
!!You Ichijou

Michiru's controlling older sister and manager.

* BathtubBonding: At home, she takes baths with Michiru and does nothing but talk about her while they're in the bathtub. You seems to see it as bonding activity between sisters, but Michiru clearly isn't comfortable with it.
* ClingyJealousGirl: She wants Michiru all to herself and doesn't approve of her forming personal relationships outside of her. Once she discovers Michiru's newfound infatuation with Miko, she tries to get Michiru transferred to another class to separate her from Miko.
* ControlFreak: She tries to control everything her sister does, from what she eats to the people she hangs out with. She even works as her manager because it gives her an excuse to control her sister's activities and schedule.
* IncestSubtext: At home, she doesn't leave Michiru alone for one second, even taking baths with her, until Michiru goes to bed and Michiru seems to be all she ever talks about. For extra creepy effect, the walls of their apartment are covered with photos of her with Michiru as if it was a StalkerShrine.
* IncestantAdmirer: She has a quite creepy relationship with Michiru where she tries to have constant physical contact with her and even makes her take baths together. Michiru doesn't openly object to any of this, but her true feelings are obvious since the spirit latched on to her head reacts the most hostilely to You.
* IntimateHairBrushing: {{Subverted|Trope}}. She likes brushing Michiru's hair and Michiru lets her do it to keep her happy, but this happens after it's been established that Michiru ''hates'' it when people touch her hair. Therefore, the scene actually serves to show how You either doesn't know or care about Michiru's personal boundaries.
* ItRunsInTheFamily: She shares Michiru's creepy obsessive behavior and total lack of respect for personal boundaries.
* MyBelovedSmother: She's Michiru's older sister instead of her mother, but fits perfectly otherwise. She's extremely controlling and clingy towards Michiru, to the point she treats her like her doll instead of a person. When Michiru starts openly defying her to spend more time with Miko, You loses it.
* NoSenseOfPersonalSpace: When she's alone with Michiru, she just can't keep her hands off her sister. Michiru puts up with it, but the spirit bonded to her shows You's behavior upsets her ''a lot''.
* {{Yandere}}: When it becomes obvious Michiru prefers to spend more time with Miko over her, You wants to get rid of Miko to monopolize Michiru's attention once more.

* GrandmaWhatMassiveHotnessYouHave: While she was younger, but still old, Mitsue was a very attractive woman.

* CastFromHitPoints: The main weakness of her protective aura is that it requires a large amount of energy to maintain and draws directly from her life force, which is why she's always constantly hungry. This is exacerbated when she's in the presence of more powerful ghosts that don't get instantly destroyed by her aura, causing her to expend more energy than normal.

* TheNotLoveInterest: Hana is Miko's BestFriend and the few times Miko tries to actively do something about the ghosts is when Hana's wellbeing is at risk. Miko constantly feeding Hana to keep her LifeEnergy up is even perceived as a PseudoRomanticFriendship by their other classmates.
* ObliviousToHatred: She thinks of Michiru as a friend and really thinks they get along, but Michiru really hates Hana because she's frequently offering her to eat junk food and more importantly, Michiru wants to steal the spot of Miko's best friend from her.

* WrongGenreSavvy: Yuria is under the misconception that she's in a typical supernatural action manga and she's TheRival to Miko who she mistakes for a protagonist with overpowered exorcism powers. She's really in a HorrorComedy and Miko's only power is seeing ghosts more dangerous than those Yuria can see, not having any ability to fight them, but Yuria's limited supernatural sight makes her misunderstand the situations she's in all the time.

* BrutalHonesty: Bluntly tells Miko that his charms won't do much against the Fox God while asking her to keep its attention anyway.

* GoodAllAlong: He takes several actions to help Miko like sending Mitsue the picture of Miko and Hana at the shrine, which allowed Mitsue to save Miko, and giving Miko one of his exorcist stones. However, whether he's a good guy is still questionable for a while. He becomes more suspicious after it's implied he's willing to use his tour group as guinea pigs to test his items on a very dangerous spirit. Mitsue also didn't trust him since she knew he had an ulterior motive for helping Miko get rid of the Shrine God. [[spoiler:At the end of the Shrine arc, it's revealed Romm's ultimate goal was freeing the ghost of the girl that was sacrificed long ago and was left trapped inside the shrine for centuries, waiting for someone to help her.]]

* PermaStubble: Has this. It helps to add to his sleazy appearance.

* BecauseYouWereNiceToMe: Although many of her classmates treat her kindly, she believes they are only interested in her because of her looks and popularity, but then quickly develops an obsessive attachment to Miko because, from her perspective, Miko is the only classmate who can tell when she's upset (because Miko can see [[EmpathyPet the octopus spirit on her head]]) and tries her best to make her feel comfortable rather than admired. She doesn't know Miko is doing that because Miko sees her as a horrifying monster whose tentacles will move to stab whoever makes her upset.

* PeekABangs: His right eye is obscured by his hair.
