Go To
Clockwise from top left - Lizlet, Shizuku, Kuesu, Rinko, and Himari

Seven years ago, Yuuto Amakawa's parents died, leaving him living alone without a single relative. Ever since then, his childhood friend, Rinko Kuzaki, has woken him up, cooked for him and generally taken care of him. The only thing he has from any relative is a mysterious charm, a red omamori, an amulet, given to him by his grandparents as a good luck charm.

On the day of his 16th birthday, this charm's power to protect Yuuto from the Ayakashi wilts and loses the power to protect Yuuto, and into Yuuto's life walks Himari. A cat spirit and samurai girl, she swears to protect Yuuto, who is revealed to be the sole descendant of a family of demon hunters. Unfortunately, Yuuto is allergic to cats. More unfortunately, there are many demons after Yuuto's life. Fortunately, many of those demons are Cute Monster Girls who end up falling in love with him. Even more unfortunately, he has to defend Himari from a particularly powerful spirit known as Tamamo-no-Mae.

Written and illustrated by Hentai artist Milan Matra, Omamori Himari is a Harem Series with lots and LOTS of Fanservice.

I shall protect you, Young Tropes:

    open/close all folders 

    Tropes A-K 
  • A-Cup Angst: Rinko is very uneasy about the size of her breasts - especially since three of the other girls after Yuuto are E-cup or above. One of them is even a T-cup.
  • Above the Influence: Yuuto, often to Himari's regrets.
    • As the series goes on, his willpower seems to be decreasing in this regard... it's getting to the point that the main thing keeping any given girl from seducing him is the other girls, who are very, very good at interrupting.
    Kagetsuki: "He is one dedicated Goody-Two-Shoes. That is not to say I don't appreciate your egging him on."
    Shizuku: "Shut know. He's just too passive."
  • Accidental Pervert: Well, it is a fanservice-centric harem comedy, so obviously Yuuto gets this quite often. And surprisingly, Rinko gets these moments on occasion.
  • Affably Evil: Shuten-douji. He had a (rather one-sided) casual conversation in his fight.
  • All There in the Manual: Volume 0, which is a collection of one-shot stories illustrated by different authors as well as including a recap of the story so far and character biosnote .
  • Ambiguously Human: After she was killed in her fight with Shuten-douji, Kuesu resurrected as the avatar of The Book of Truth note 
  • Animate Inanimate Object: Lizlet is a teacup. To be more precise, she's a Tsukumogami, a normal object that became a living thing after being used for 100 years.
  • Arranged Marriage: Between Kuesu and Yuuto. Though to the former, it is a Perfectly Arranged Marriage.
  • Art Evolution: From the first chapter to somewhere around chapter 20, Yuuto looks, to say at the least, pretty weak. From there on, the art seems to get better and better, and it especially becomes more noticeable in the later chapters like in chapters 50 and above.
  • Artificial Riverbank: In the anime, the site of the first encounter with Shizuku. In the manga, it's a river in a small forest (or very big park?).
  • Because You Were Nice to Me: Several of the girls fall in love with Yuuto largely because he treats them well, such as Lizlet.
  • Bed Full of Women: Happen to Yuuto in the last chapter while his consciousness is separated from his body. When he returns to his body, awakens to find out that over half of his harem has had their way with him in his sleep (see Dude He's Like In A Coma).
  • Berserk Button:
    • Himari has a Heroic BSoD when Yuuto is severely injured while she is trying to guard him. She has feelings for him and has an oath to protect him with her life; push both of those buttons and you will get hurt.
    • For Kuesu, do not call her out on her family's heritage, and especially don't harm her beloved Yuu-chan, or else she will bring <Death> upon you. Shizuku and Shuten learned this the hard way.
    • In the anime's final two episodes, it doesn't even take an actual threat — just to IMPLY one is enough.
  • Big Bad: Tamamo-no-Mae, the Fair-faced Nine-tailed Fox. Reduced to a fragment of herself after being slain hundreds of years ago, she seeks to regain her full powers by devouring other ayakashi. She wants Himari Noihara, a particularly powerful ayakashi, as her main course and attempts to goad Himari into using her demonic powers to make her especially "filling."
  • Bland-Name Product: In chapter 56, Kuesu is holding what seems to be an iPad, with a cherry logo on the back.
  • Bodyguard Crush: And it doesn't conflict with Himari's "sense of professionalism" at all. Although, for some odd reason, while she has no qualms about pushing Yuuto down to try to seduce him whenever possible in the most obvious ways, she barely manages to talk when she asks for a kiss later.
    • This is lampshaded by Himari, being a cat unfamiliar with human intimacy. Though, after a Accidental Kiss, she quickly wants to experience more.
  • Boring, but Practical: Kuesu's magic attacks take some time to charge up and are highly directional. That's why she also relies on a plain old handgun.
  • A Boy and His X: A boy and his cat demon bodyguard who fights for him (Or, as someone put it on a forum: "There's nothing like the relationship of a boy and his cat, snake, tea cup, best friend, and fiancee.")
  • Breaking the Fourth Wall: When Yuuto knocks Himari out of the path of danger and ends up groping her in chapter 47, his reaction...
    "Ah... there was a scene like this in chapter 1."
  • Brutal Honesty: Shizuku has this tendency. She shamelessly lampshades her appeal to lolicons, and in one instance, after Yuuto fainted in a bathtub, and woke up fully clothed:
    Rinko and Himari: "I didn't see anything!"
    Shizuku: "They had a good look at everything."
    • To say nothing of her Intimate Healing moments...
      Himari: "Why did you have to hug him naked?"
      Shizuku: "It made me...... feel so good...... Don't make me say such embarrassing stuff."
  • Cat Girl: Himari. Played for laughs in that Yuuto happens to be allergic to cats.
    • And there's the scene where Himari swallows a medicine pill that would heal her, but initially would "shut down" her human side and make her go completely primal. Yuuto was worried at first that she would turn violent or be in pain, but as he hilariously found out, Himari's mind was merely turned into that of a playful cat, and with Yuuto right in front of her, she had her fun.
    • And in Book of the Gaiden, Hime. Too bad it didn't end well for her in the end.
  • A Chapter in the Limelight:
    • Rinko has two: one in chapter 9 and another in chapter 23.
    • Lizlet in chapter 27.5.
    • Kuesu also has one during her introductory arc, as well as Volume 0 via Flashbacks.
    • Himari also has one in Volume 0 and in Book of the Gaiden, both via Flashbacks.
    • Shizuku gets a whole story arc in the limelight, from chapter 31 to chapter 33.
    • Don't forget chapters 37.5, 48.5, and 56.5 for the minor characters.
  • Chaste Hero: Yuuto. Much to the disappointment of the girls. And him.
    • Subverted in the ending. While no one officially got married, Yuuto is now living with a dozen girls, half of whom had SEX with him, and he seems to be going along with this.
  • Childhood Friend Romance: Three members of the Unwanted Harem are Yuuto's childhood friends: Himari, Rinko, and Kuesu.
  • Childhood Marriage Promise: Yuuto and Kuesu. It was arranged by his grandparents, and Yuuto promised Kuesu he'd "protect her back", since her offensive spells mostly go forward.
  • Class Representative: A reoccurring glasses-wearing side character.
  • Clingy Jealous Girl: Pick a girl, any girl, in the de facto harem. Lizlet is the only exception (she's still clingy when she sees Yuuto, just not jealous of others).
    • Rinko gets incredibly jealous and mad at Yuuto when Himari first shows up, and challenges her to some sports. And loses quite badly. She also gets mad at him whenever the other girls try to seduce him.
    • Himari herself experiences this when Kuesu first appears, and kisses him twice. Despite trying to ignore it, it bothers her so much that Himari demands that Yuuto give her a kiss as well. She will also occasionally leave her cat ears/tail out to "punish" him, such as in chapter 14 after three of the girls smother him while "training" him.
  • Clothing Damage: In a Fanservice-filled series where Cute Monster Girls fight each other? Surprisingly, it happens only once. And only subverted. In the first fight between Ageha and Himari, Himari slices Ageha's top... and instantly asks her to fix it, since Yuuto is still there and she doesn't want him to see another girl's breasts.
    • It happens again later — once to Himari, when Tama first shows up, and then again to Ranka Mikari. Both times, though, it's just a slash to the top, enough to show the bra underneath but not enough to actually remove the top.
    • Played completely straight in a chapter title page, though, even though it doesn't happen at all during that chapter.
  • Conveniently Seated: Yuuto sits on the second to last row, by the window. Himari requested the seat beside him and got it.
  • Cool Gate: Kuesu later creates one from her hotel room to the closet in Yuuto's room.
  • The Corruption: Himari absorbing Tama's evil youki in chapter 63 has caused her to slowly undergo this. She eventually gave into it as of chapter 69 when she and Tama's Co-Dragons attack Yuuto's school.
  • Couch Gag: Who will Rinko find in bed with Yuuto at the end of the opening this time?
  • Creepy Child: Shizuku, oh so much, in so many ways. Tama might be even worse, but not nearly as obvious.
    • Yuuto was one of these as a child according to Rinko. Of course he got better.
  • Crouching Moron, Hidden Badass: Lizlet — a ditzy maid waitress who is strong enough to toss a human really high... with one hand, and then jumping up to join him! And probably even more impressive: she's a tsukumogami, and her apparent body is just a manifestation of the ghost of an old British tea cup. "Hurting" it ruins her clothes (at best), as you need to destroy her real body to hurt her — the tea cup. Still, she seems far less badass than most of the others around, even in her better moments.
  • Cute Monster Girl: Pick a girl, any girl, except for Rinko and possibly Kuesu — who is a witch instead.
  • Cute Mute: Tama. Subverted; she's devouring fellow youkai and demon hunters to increase her own power. And she doesn't really care if they're dead or not before she starts eating. And what's more, by the time she's done feeding, she turns out to be a Kitsune, and has already acquired Nine Tails, making her an Eldritch Abomination!
  • Dangerous 16th Birthday: Yuuto's sixteenth birthday is when his protective charm ran out of juice.
  • Death by Genre Savviness: Discussed in chapter 35:
    Class Rep: "...But my sixth sense is tingling..... it's telling me there's danger near. If something happens here, I'll be the first to die... (Like a Christmas murder...)"
    Kuesu: "Ohoho! The candle that burns twice as bright, burns half as long."
    • It almost happened.
  • Defeat Means Friendship: Played straight and flipped around (Friendship means Defeat): Yuuto's wide-open heart and absolute belief that fighting is not the way to solve problems is enough to stop fights and win over another girl to the harem.
  • Died in Your Arms Tonight: Kuesu died in Yuuto's arms after taking a brutal hit from Shuten-douji after blasting him with her Kamehame Hadoken spell. She got better in chapter 64 during her Big Damn Heroes entrance.
  • Didn't Think This Through:
    • Hyogo Kaburagi, the Section 4 guy. Yes, making a deal with an Always Chaotic Evil demon to not harm humans, who's pissed off at humans for stopping him a long time ago is not going to backfire in any way.
    • Lizlet really should have stored her teacup body somewhere safe, preferably securely wrapped in polyfoam and locked in a safe, since she'll die if the teacup breaks. But no, she just leaves it in a cupboard in the shop where everyone can see and does not even bother to shut its doors. If it wasn't for Yuuto, she would have died many times over.
  • Disproportionate Retribution: When Kuesu was a student at the Royal Magic Society, another student put a dead mouse in her soup. Kuesu retaliated by casting a spell that destroyed the other girl's right eye. On the other hand, mice and their corpses carry some rather nasty diseases like bubonic plague.
  • Does This Remind You of Anything??:
    • Ageha's reaction to sucking Yuuto's blood is...suggestive, to say the least.
    • Lizlet's reaction to Yuuto drinking from her teacup is even more suggestive.
  • Don't You Dare Pity Me!: Being a warrior who respects honor, Himari occasionally takes offense to Yuuto's kindness when something bad happens to her.
  • Dope Slap: Unusual for a harem comedy, Yuuto is shown to be willing to deliver the occasional slap to one of the girls instead of simply being on the receiving end all the time.
  • Double Standard Rape: Female on Male: In the finale, an unconscious Yuuto had an eight-way orgy, which Kuesu apparently started.
  • Dude, She's Like in a Coma: Near the end of the manga, Yuuto goes into a slumber for days to allow his consciousness to search for Himari, who sealed herself away in order to prevent her evil side from resurfacing. When he finds her and returns to his body, he awakes to find out that over half of his harem had their way with him in his sleep. Specifically, Kuesu, Shizuku, Lizlet, Ageha, Aya, and even Tama's flunkies from the last battle (Ekou and Kurozakura). Finally, Rinko, the class president, and Kaya walk in on them and are highly unamused at what they see.
  • Dude in Distress: The only reason Himari doesn't need to constantly rush out to save Yuuto is that she's usually already with him and can save him right away. Still, it happens.
  • Elegant Gothic Lolita: Kuesu. Minus the Lolita (that's Shizuku's job).
  • Elemental Powers: Besides Shizuku, there's also Yuuto and Kuesu, and some (though not all) other demon slayer clans have elemental powers as well.
  • Emotionless Girl: Shizuku's facial expression almost never changes... almost.
  • Enemy Mine: Ageha and Sasa, who attempted to kill Yuuto in Noihara, team up with him after they find out Tama is killing and eating Ayakashi. This takes a lot longer in the manga than in the anime.
  • Even Evil Has Standards: In Chapter 50, after learning Tama has mind-controlled the Class Representative/Yuu Shimamura and is hatching a plan, Shuten-douji silently expresses distaste for using the human as a hostage.
  • Everyone Calls Him "Barkeep": The Class Representative of course, her real name is Yuu Shimamura.
  • Evolving Credits: The girl in bed with Yuto when Rinko walks in during the opening changes every episode, usually whichever girl(s) gets the focus that episode. Sometimes the closing credits show slightly different images, or has one main girl singing throughout the song rather than splitting it between the 5 of them.
  • Expressive Hair: Shizuku's hair grows when she fights Kuesu, and shrinks back after the fight. It's probably related to anger, but it's hard to tell with her being an Emotionless Girl.
    • It is later shown again in her fight against Ranka Mikari, where she actually does show her thirst for revenge.
  • Expy: Himari looks like many of Matra Milan's main heroines from his early professional Hentai works — take Kanari from Palladium Garden. Kuesu is ripped straight from a character of the same name in Palladium Garden.
    • Tama looks vaguely similar to Milcolette/Kelly, also from Palladium Garden.
  • Fan Disservice: Aya when she pukes out weapons and other things from her stomach.
  • Fantastic Arousal:
    • It's all but stated that Lizlet's teacup body is actually quite sensitive in this way. When Yuuto drinks from Lizlet's teacup. Her reaction to Yuuto stirring sugar into his tea is like she's receiving some serious foreplay. Her reaction to him putting his lips to the cup is even more explicit.
    • Averted by Himari, whose cat tail and ears are no more sensitive than the rest of her body.
  • Fantastic Racism: All fanservice-and-comedy said and done, monster or not, one has every right to hate someone when their family has taken everyone you love away from you. How he or she acts on that hatred, on the other hand...
    • And even between Japanese Inquisitors, the very act of learning Western Magic will earn you nothing but contempt and mockery amongst supposed allies. Just ask the Jinguuji family.
  • Festival Episode: Yuuto and Rinko visit a temple festival every year.
  • Fille Fatale: She might be Really 700 Years Old, but Shizuku is still the Token Mini-Moe here, and intending to seduce the main character.
  • First Girl Wins: At least three possible interpretations — Kuesu was the first girl Yuuto kissed (once before his memory was sealed away with his powers, twice after, and only then comes a kiss with Himari), Rinko was the first girl Yuuto met when he moved out to live on his own and the first to interact with him in the story, and Himari was the first girl to be shown in the manga. Right now it seems that the series is going in the direction of having Yuuto and Himari be the Official Couple. Not surprising, considering that her name is in the title...
  • Forceful Kiss: Kuesu kissed Yuuto twice in front of Himari, and then told her that the second is actually the third.
  • Forgotten Childhood Friend: Well, they aren't villains, but both Himari and Kuesu had been forgotten by Yuuto at the beginning of the story. Much to the consternation of both. To be fair however, the Protective Charm his grandparents gave him to hide his presence from Ayakashi also suppressed his childhood memories.
  • Funny Background Event: At one point, Yuuto is seen playing videogame, where Himari and Shizuku appear as characters
  • Gas Leak Cover-Up: Used to explain the damage caused by the fight between Kuesu and Shizuku. When Kuesu learned of the coverup on the news, she commented that this was the first time she'd heard of someone installing gas lines on the ''top'' of a building.
  • Gecko Ending: The anime ended at 12 episodes, with the final two bringing to a end two major villans whose plotline is still unresolved in the ongoing manga (at the time). The final two are original to the anime, obviously.
  • Genius Bruiser: Kuesu packs the most power out of all the haremettes despite being human (just ask Shuten in his last bout with her) and has the most brains due to her mastery of dark magics and as a result of coming in contact with a forbidden Great Big Book of Everything while studying in England.
  • Genre Savvy: The Class Representative, who thinks that Rinko should throw herself onto Yuuto, because the girl who did that in a harem game she played won!
  • Girl on Girl Is Hot: Chapter 37. To quote from Taizo: "Looking good there, maids."
  • Good Thing You Can Heal: Subverted: Himari, who does heal faster than a human, is only injured in serious fights; Shizuku, who seems to have "dissolve into water and reappear" as standard reactions to injuries like, um, being sliced in half manages most of her fights (well...3 of 5) without a scratch; and Lizlet, whose body is invincible, just got stabbed twice in one fight. Basically, the better you heal, the less often you get injured...
  • Happiness in Slavery:
    • Himari is more than happy to be Yuuto's servant and bodyguard. To give Yuuto credit, he really IS kind and caring towards her (and everyone else). Nonetheless, technically, she's a slave.
    • Lizlet wants to be Yuuto's 24-hour maid. She isn't but she certainly would enjoy it if she was. And it's possible for him to buy her legally, if her current owner agreed.
  • Healing Factor: Rather minor compared to other examples, but it's mentioned several times that Himari heals faster than humans. It still takes her usually at least a day to recover (from injures that probably would take weeks for a human).
  • Heroic BSoD: Himari suffers one after Yuuto gets stabbed in the back shielding her and appears to die.
    • In the anime, she suffers another after Shuten-douji threatens Yuuto (just 'threatens'', mind you). She then shows what a Superpowered Evil Side really IS.
  • Hotter and Sexier: In the anime, Ageha undoes her top (censored in the TV broadcast) during her second appearance and dresses in a Stripperiffic Sailor Fuku just just to get herself riled up.
  • How Do I Shot Web?: All information on how to use the Light Ferry was passed from father to son in an oral tradition. Unfortunately, since Yuuto's father and grandfather both died before passing the information down, he doesn't know anything about how his powers work and has to figure it out from scratch.
  • Hypercompetent Sidekick: While Yuuto does get stronger over time, it's still Himari who does the fighting.
  • Hyperspace Arsenal: Subverted with Himari, who has her sword always visible as long as she has it, and (somewhat) justified later with Aya, a demon messenger who keeps things in her stomach.
  • Idiosyncratic Episode Naming: Each chapter of the manga includes either the kanji, hiragana, or katakana for "cat" within the title.
  • If It's You, It's Okay: In chapter 29, Kuesu, Himari, and Rinko say how they think peeking is a crime, and then think to themselves it would be okay if Yuuto did it.
  • If You Kill Him, You Will Be Just Like Him!: A very nice twist on this trope as the person Shizuku wants to kill isn't a villain but the innocent descendant of the demon slayers that murdered her family.
  • I Just Want to Be Normal: Yuuto just wants to live a peaceful, normal life.
  • I'm a Humanitarian: Tama and Shuten-douji. They're actually eating other ayakashi in order to grow their own power, as well as demon hunters and other humans with spiritual power.
  • Improbably Female Cast: Ok, it is an Unwanted Harem, but seriously: In 70 chapters so far, 9 males were allowed to speak. One wasn't even named, both Shizuku and Kuesu have someone who works mostly as a messenger to other demons and Demon Slayers respectively, another got an Unsettling Gender-Reveal, another is a one-person version of Those Two Guys, then there is the male villain, and, at last, the protagonist. The most guys talking in one chapter was three, and that happened only once.
  • Ineffectual Death Threats: It's strongly implied that Ageha's death threats became this.
  • Interspecies Romance: Boy meets Cat Girl, snake demon, Tea Cup and more.
  • Insane Troll Logic: From Shizuku: "Kotatsu leads to naughty things."
  • Intimate Healing: After Yuuto gets stabbed in the back in a fight, Shizuku proclaims that her water magic can be used for healing and, well, does so while Himari is looking on.
    • In a later chapter Himari gets covered in snow after battling a grown-up Tama at a ski lodge and tries to get Yuuto to do the "warm up via shared body warmth" routine. To her extreme disappointment, he takes her to the lodge's hot springs instead.
  • Invisible to Normals: There are spells that ward off humans, and "Public Safety Division 4" cleans up the mess afterwards.
  • I Shall Taunt You: Kuesu transforms Himari into little girl as a practical joke, and later calls her to taunt her by asking if she likes it. Himari decides to taunt her back by claiming Yuuto is more of paedophile than she thought, and was very pleased with the change in her. Kuesu angrily claims its a lie, but later reveals that she bought it.
  • It Was a Gift: Rinko's hair ribbons, which she never removes because they're a gift from Yuuto.
  • Katanas Are Just Better: Played straight by Himari. Justified by the fact that her sword is a legendary sword. Not that this keeps it from being completely fried by a certain witch, but it makes the "repairing" of said sword harder..
  • Kill the Cutie: Hime, a fellow cat ayakashi Himari befriended, at the end of Book of the Gaiden because the Amakawa family's law dictates that any cat ayakashi under them who falls to her primal instincts must be killed on the spot. Thus Himari was forced to kill her when she saw her consuming the flesh of a human girl whose grandmother was once her owner. Also counts as a Tear Jerker moment for Himari.

     Tropes L-Z 
  • Magnetic Girlfriend: Also Himari. All the Cute Monster Girls seem to have come out of the woods right after Himari entered Yuuto's life, although that has more to do with the awakening of his demon-hunting powers when he turned 16.
  • Magic Pants: Entirely absent. Himari leaves her sword and clothes behind when she changes into a cat, and is naked when she turns into a girl again.
  • Mahou Shoujo: Himari gets the full transformation treatment after Yuuto gives her the Light Ferry at the end of the anime, complete with airborne clothes-changing and frilly tutu. Think Sailor Moon with a demonic bent.
  • Making a Splash: Shizuku comes from a family of mizuchi (essentially borderline dragons/snakes) who were worshiped as water gods. Naturally, this is how she fights.
  • Masquerade: More as a side note. The "Public Safety Division 4" usually keeps things secret in Japan and works together with the Demon Slayers. Other nations are stated to have similar groups.
  • Marry Them All: Essentially how it ended. While no one officially got married, Yuuto is now living with a dozen girls, half of whom had sex with him, and he seems to be going along with this.
  • Mercy Kill: Himari had to do this to Yuuto's grandfather before the start of the series. She honestly believes that Yuuto would (and should) treat this as a violation of the compact between their families and execute her upon finding out. He doesn't.
  • Morality Chain: Yuuto is this in various degrees, to various characters.
    • Himari nearly falls into a blood rage several times — stopping herself since Yuuto wouldn't like it.
    • Kuesu would love to exterminate all demons on earth, even the innocent ones — but doesn't, since Yuuto would hate her for it.
    • Shizuku would have killed the (innocent, powerless) descendant of the Demon Slayers that annihilated her clan, but stops for the same reason as Kuesu.
    • This is what finally causes Yuuto's power to manifest in the concluding episodes of the anime...after the climax, he can no longer use his power consciously. He or someone he cares about must be in mortal danger. In the manga, he's unable to use it unless threatened from the very beginning. He learns to use it by choice instead of instinct in fights, but still needs real danger (to him or others) to do so.
  • Morphic Resonance:
    • Subverted: Himari is a white cat, and as a changes to black. Lampshaded by Yuuto in an omake.
    Yuuto: "Shouldn't you stay white, since it's easier to draw?"
    • The same omake explains that the hair color was inspired by another character's (Kuesu).
    • In the anime, Himari undergoes a further transformation in the final two episodes, when supposedly she gives herself FULLY over to her demon side. Her hair changes to white, her WHOLE BODY sprouts fur and gains marks, and her head/face become decidedly more cat-like. CRAZED cat-like, with red eyes.
  • Ms. Fanservice: Dead heat between Himari and Lizlet.
  • My God, What Have I Done?: After Yuuto confronts Kuesu in chapter 21 about his reasons not to marry her due to her unwillingness to coexist with Ayakashi, she attacks him with a knife, causing his Light Ferry ability to activate. She gets thrown out of the hotel room due to its force, and Yuuto suddenly remembers a forgotten memory with her where he wanted to protect her and help her defeat Ayakashi. He begins to regret everything he just told her, as she held onto his promise all this time. Fortunately for him, she manages to teleport herself back into the room, then tries to find some common ground with him so he wouldn't hate her so much, such as not attacking Himari.
  • Naked First Impression: Shizuku. It's not really a first impression, but it still kind of applies: After having fought her the day before, Yuuto finds her in his bathtub the next day... And while he faints shortly after, she keeps her usual expression
    • It should be noted that Yuuto is the one naked (taking a bath), while Shizuku wore as much clothes as usual...for her.
  • Not So Stoic: Shizuku barely shows any emotions other then smug and snarky, but when she finally realizes that her blind desire for revenge was ultimately both pointless and self destructive, she breaks down in Yuuto's arms.
  • Older Than They Look bordering on Really 700 Years Old: Oh my, Shizuku. A 100+ year old demon who looks like a ten year-old girl with a really long tongue.
  • Ordinary High-School Student: Yuuto and Rinko. Rinko in particular gets constantly reminded by other characters that she's this.
  • Orphan's Plot Trinket: Well, it already loses importance and power in the first chapter, but Yuuto had a charm to protect him from demons for several years, and he's an orphan...
  • Our Vampires Are Different: Ageha's abilities as a Hinoenma is that she can suck blood (mostly from men) without any negative effects (other than the obvious things that come from losing a lot of blood). So she doesn't have to kill when she doesn't want to.
  • Patient Childhood Love Interest: Rinko started off as this, but it later turns out Yuuto had an Arranged Marriage and Childhood Marriage Promise with Kuesu before his memories were sealed. And lets not forget Himari herself.
  • Parental Abandonment: All over the place, in varying degrees.
    • Yuuto's parents and all of his relatives have died, including his grandparents that gave him his charm.
    • Shizuku's entire clan got killed.
    • Himari's mother died in childbirth and she never knew her father but believes it may have been a different kind of cat spirit or a wildcat (she was raised by Yuuto's grandparents, who are also dead).
  • P.O.V. Boy, Poster Girl: Himari may be the series' Title Character and heroine, but Yuuto is the primary viewpoint protagonist.
  • The Power of Love: Played more or less straight but without the Narm usually involved. Yuuto's absolute conviction that everyone can get along has a genuine effect on most of the characters. His sincere honesty makes them at least stop and think about their actions, if not outright reconsider their motives. Heck, he broke Shizuku out of something like 100 years worth of seeking revenge by refusing to accept her denial of friendship and a hug.
  • Protective Charm: Yuuto was given one by his grandparents to keep him safe from demons until his 16th birthday. As shown in the beginning episode 1 of the anime, it begins to weaken, and the demons slowly become aware of his presence and attack. Fortunately Himari also arrives to protect him as well. See Title Drop below.
  • Psycho Lesbian: Kaya is heavily implied to be this way in terms of her feeling towards Himari and her actions towards those who get in the way. Pretty much confirmed in volume 0 when she's seen sniffing Himari's underwear.
  • Psychic Link: Tama seems to be unable — or unwilling — to communicate in any other way. Slowly averted in later chapters.
    • Though it's never actually explained what it is. It might be anything from Mindlink Mates to actual telepathy. Or Shuten-douji is just the only one who knows her enough or is observant enough to note what she means.
  • Really 700 Years Old: Shizuku with an age of at least 100 years. She explains her household skills by noting that before the destruction of her clan, daily chores like cooking and cleaning were more important than fighting... Said destruction was about 100 years ago. Also Lizlet to a lesser extent, since she manifested from a tea cup after 100 years of activity.
  • Red Eyes, Take Warning: Shizuku and Himari when her Superpowered Evil Side takes over.
  • Refusal of the Call: It's said that other Demon Slayers sealed their abilities, as did Yuuto's parents (specifically his father since his family's abilities are passed down to the male side), probably. Yuuto himself is thinking about it.
  • Samurai: Himari fits this, and Rinko calls her "that samurai girl" early on.
  • Scooby Stack: The anime ends with one featuring so many girls that they don't all fit along the doorframe.
  • Sealed Evil in a Can: Seemingly, Shuten-douji and Tama had been this. However, they're already free again (although just "shards") and are now trying to regain their powers.
  • Shapeshifting: Most demons have their true form, a human form, and at least Himari has something in between.
    • The anime gives her both her normal forms from the manga, a true form that can be viewed as terrifying, and an enhanced form when Yuuto uses his powers on her in the climax. Both of the last forms are in the two episodes that do NOT use manga chapters as the plot lines.
  • Shout-Out: To Neon Genesis Evangelion after Kuesu comes back from the dead.
    Kuesu: Don't joke around and tell me I'm the third incarnation of myself!
  • Show Within a Show: In chapter 37, second panel, Yuuto's playing a video game...of Himari fighting Shizuku.
  • "Shut Up" Kiss: In chapter 66, Yuuto gives one to Kuesu after listening to her condition, too bad that Himari saw them.
  • Single-Gender Race: Himari's ayakashi species (Bakeneko, or "monster cat") only births females.
  • Single-Target Sexuality: Himari is "only interested in [her] master" and her body "belongs to him alone." And now add several attempts of her to seduce him.
  • Slasher Smile: Shizuku, occasionally.
    • Himari gets this occasionally as well... such as in chapter 36.
    • Hitsugi Yakouin, at the bottom of the page in chapter 46.
  • Soul Jar: This is the actual "Badass" part of Lizlet's Crouching Moron, Hidden Badass. Lizlet is by far not the only rather strong girl in this series, but being sliced and stabbed and just complaining about the ruined clothes? Being the manifestation of a sentient tea cup has its advantages.
  • Sprouting Ears: Himari can actually do this, but her ears and tail are enough to trigger Yuuto's allergies, so she only does so if needed...or to threaten him ("I shall let out my ears and tail and meow"). if sufficiently angered, she'll do more than threaten him...
  • Story-Breaker Power: Yuuto's inborn ability, Light Ferry, essentially increases the attributes of whatever he wants. There seems to be no limit on what he can increase or how far the increase will go. Its heavily implied that if he had full control of his power he'd be invincible.
  • Superpowered Evil Side: The "Berserker"-version. Shizuku warns Yuuto that basically any demon, no matter how "civilized", might lose to its instincts, even Himari and herself.
    • In the anime, Himari does just this in the final two episodes to defeat Tama and Shuten-douji. berserk doesn't even begin to spell it out — she becomes destruction personified. Yuuto snaps her out of it with a hug and The Power of Love.
  • Supporting Harem: Out of all the girls, Yuuto cares about Himari the most. Not that it stops the others, especially Rinko and Kuesu, from trying to hook up with him.
    • In the manga, they're actually pretty much on equal footing. Of course, Himari's still the only one with her name in the title...
  • Technical Pacifist: Yuuto is very close to this, at least partially. He really doesn't want to hurt anyone, and only does so if it is a matter of life and death... But still, he does let Himari fight for him. If Yuuto would fight, he'd probably be this. Himari is this because Yuuto ordered it.
  • Thanks for the Mammary: It's a Running Gag that this happens every time Yuuto falls onto a girl. Unusually for this trope, the girls often don't mind. Himari only objects if he does it during a battle or training session.
  • Thou Shalt Not Kill: Yuuto doesn't want anyone to get hurt. Most other characters are less friendly.
    • In the anime, He finally recognizes that he can't save everyone, and uses Light Ferry to power up both Himari's sword and Himari, in order to kill Shuten-douji.
  • Title Character: Himari, duh!
    • Which quickly becomes a Title Drop since Himari's role in the story is to protect Yuuto from ayakashi that seek to kill him after his protective charm (called an omamori in Japan) stopped working. In other words, she is Yuuto's new protective charm, or Omamori Himari.
  • Token Mini-Moe: Shizuku and Tama (introduced in chapter 28 of the manga). Lampshadedand enforced by Shizuku whenever another little girl appears:
    When Himari is transformed: "There's only room for one loli in this house." (accompanied by strangling her)
    After Tama appeared: "I'm the only loli allowed in this area."
    • As of chapters 41 and 42, Tama no longer applies all the time, being able to temporarily assume a curvy adult form. She reverts in chapter 43, and Shizuku repeats her objection.
  • Training from Hell: Yuuto tries this once with Shizuku, but without success — since she can't bring herself to actually hurt him, the training doesn't work. Then, Lizlet, Rinko and later even Himari show up, and it turns into Training From Marshmallow Hell...
    • The training he now recives from Himari seems much less severe, though.
  • Transfer Student Uniforms: Himari keeps her "old" school uniform (or at least a different one) to warn demons who plan to attack Yuuto that she is there to defend him.
  • Traumatic Superpower Awakening: Yuuto's Light Ferry ability seems to work on this principle, at least early on before he can summon and control it at will. Shizuku even points this out to him in chapter 14 and episode 5 during their mock battle, where it didn't activate due to her unwillingness to really attack him and put him in real harm's way. Unlike when Ageha attacked and sent Himari into an Unstoppable Rage, and later with Kuesu attempting to stab him after he rejects her marriage proposal.
  • Traveling at the Speed of Plot: According to Matra in the Volume 9 afterwords, the story hasn't even reached one full year over the course of the 7+ years he has written it.
  • Tsundere:
    • Rinko is a bit of this, being mostly nice to Yuuto... Except when something gets in her way. Not enough for a Yandere, though.
    • Also Ageha, the Hinoemnma. What makes her different from a Yandere is that her "Males are food" attitude is NORMAL for her, and her sympathy (as far as there is any, as she's VERY tsuntsun) only goes so far as to not trying to kill Yuuto. Oh, and wanting to rape him.
    • Kuesu, too, being a commanding Ojou. Lampshaded by Himari.
      Himari: "'Yuu-chan?' So you go from hard as nails (tsuntsun) to soft as putty (deredere), is that it?"
  • Two-Teacher School: Ms. Kisaragi, who (judging by an class trip where students were supposed to find motives to draw) probably is an arts teacher...
  • Unstoppable Rage: Don't hurt Yuuto, or Mama Bear Himari will make sure you end up as mincemeat.
  • Unusually Uninteresting Sight: People who aren't fooled by the Masquerade and don't get hit with Laser-Guided Amnesia from mindwiping spells will... not seem to particularly question why Shizuku appeared out of a lake or why Yuuto, Himari, and Rinko are talking about witches (demon slayers) all of a sudden.
    • Or the Big Damned Sword being carried by the extremely buxom, old-fashioned-kimono-wearing Himari.
    • Subverted by the Class President, who's noticed the strangeness of Himari's enrollment and the phenomenon that keeps occurring.
  • Van Helsing Hate Crimes: The Demon Slayers want the ayakashi dead. Sometimes, there are minor exceptions and a demon gets spared, which led Himari's ancestors to serve the Amakawa family, but mostly...
  • Verbal Tic: Shizuku's "na no".
  • Violently Protective Girlfriend: Himari is VERY protective of Yuuto. The other girls wouldn't hold back either.
  • Wham Episode: Chapters 11 and 12 of the manga (episode 4 of the anime), when Yuuto and Himari run into Ageha, the first Ayakashi that doesn't want to reason with him unlike others he's run into so far. He also gets seriously injured, causing Himari to go into an Unstoppable Rage.
  • What Measure Is a Non-Human?: In Kuesu's opinion, or the opinions of most demon hunters? None at all. In Yuuto's opinion? Same as a human.
  • Wise Beyond Their Years: Shizuku, who is Really 700 Years Old, but of course doesn't look like it.
  • Yandere:
    • Kaya when it comes to Himari.
    • Kuesu (to some degree) for Yuuto, although that's more arrogance and a ploy to forcefully awaken Yuuto's power and reawaken his memories, she becomes Tsundere after that. In chapter 21 (episode 8 of the anime), however, she clearly has that look in her face that many other females who fall into this trope have when she attacks him..
    • Rinko could count as well, although that's more Tsundere drifting into Comedic Sociopath territory, since it's only Played for Laughs.
    • Also, both Himari and Shizuku can be violently crazy (yan-), but that's (mostly) unrelated to their feelings for Yuuto (-dere), so while the name fits, they aren't actual examples.
  • Ye Olde Butcherede Englishe: At least in the fan translations, to emulate the archaic Japanese spoken by Himari in the original. It gets pretty bad. Later subverted in recent fan translations, and completely averted in the official translation.
