[[caption-width-right:316:Natsume Takashi & Nyanko-Sensei.]]

->''"Ever since I was little, I have sometimes seen strange things. As others cannot see them, they are most likely what you would call '{{youkai}}'". ''
-->--''Natsume Takashi''

A {{shoujo}} {{manga}} by Yuki Midorikawa and fifty-two episode anime. Also known as ''Natsume Yūjinchō''.

Natsume Takashi is [[ISeeDeadPeople one of those manga protagonists]]. All of his life, he has possessed the ability to see spirits. He's been tossed about from home to home for most of his life, unable to fully interact or be honest with people due to the way they tended to react to his bizarre ability. As a result he is NotGoodWithPeople ''at all''. So yeah, kid's got {{angst}}.

Natsume's ability to see spirits is a power he inherited from his grandmother, Reiko, who made a personal hobby out of gathering the names of as many spirits ("{{Youkai}}") as possible binding them to her servitude via writing their names in the titular Book Of Friends - a highly prized item that many denizens of the spirit world desire for themselves. Upon her death, Reiko bequeaths to her grandson several of her belongings - including the Book.

Upon discovering the purpose of the Book of Friends, Natsume makes it his mission to return all of the names his Grandmother took to their appropriate spirits. Yes, including the evil ones who want to kill him. He spends his time releasing the various spirits that come to him for help from their contracts and trying to stay alive in the face of the ones who'd rather just eat him and take the book for themselves.

One spirit in particular, Madara (aka Nyanko-sensei), who spends most of his time in the body of a [[ManekiNeko lucky cat]] (when he's not going OneWingedAngel on us in which case he appears to be an [[CanisMajor giant inugami]]), is particularly helpful when it comes to the not-letting-Natsume-get-eaten thing. He serves as Natsume's bodyguard and spiritual adviser, and his main motivation is apparently to possess the Book of Friends - which Natsume has promised to Madara, should he be killed.

There is an anime based on the manga, in four thirteen-episode seasons (the third aired in the Summer2011AnimeSeason and the fourth in the Winter2012AnimeSeason).

An appropriate word of description for this series would probably be "heartwarming". It's been described as "{{Tactics}}, but less violent", though it definitely has its moments. The occasional outbursts of action are balanced out against gentle explorations of the supernatural, basically it's a light-on-plot, SliceOfLife take on the spirit world, and a sometimes exciting, sometimes peaceful foray into the world of the supernatural. And it's packed with more CrowningMomentsOfHeartwarming and {{TearJerker}}s than you can shake a stick at.

Many of the chapters, especially in the first-half, were stylized to be closer to stand-alones so that anyone starting the series could have a basic understanding of the plot (though some stories are up to three chapters long).

[[folder: Tropes Used. ]]


[[foldercontrol]]

[[folder:A-I]]
* AbusiveParents: Natsume once had an abusive drunk as a guardian, and another that purposely neglected to feed him.
* AdorablyPrecociousChild: The kitsune boy all the way. Maybe Kai too, with a dash of {{Tsundere}}?
** Natsume when he was a child
* AdultsAreUseless: Subverted. Many of the adult characters in the series, some without who don't have or even know about the ability, make positive impacts in Natsume's life. While sometimes they do require Natsume's ability for help, they also do their fair share of work. Justified for some adults in Natsume's childhood since they can't see ayakashi.
* TheAlcoholic: Nyanko-sensei, and a lot of the recurring youkai.
* AmbiguouslyHuman: Some youkai look very human-like to the point where occasionally Natsume and even Nyanko-sensei can't tell them apart. However, Natsume's ability to differentiate seems to be more powerful compared to some exorcists.
* AndroclesLion: Saving youkai occasionally turns out to be unexpectedly useful later on.
** One extremely powerful youkai jumps to Natsume's defense, saving Natsume and Natori from an evil ayakashi trying to eat them, because Natsume helped him earlier in the episode. This is a pretty big reward considering all Natsume did was [[spoiler: cover up a puddle in the road so that his servants could pass despite the fact they could just as easily have ''walked around it''. It was probably a SecretTestOfCharacter or something...]]
*** It might have more to do with the East Asian concept of honor and duty. Quite a few Chinese (and I'm sure Japanese as well) folktales have people or spirits repaying small debts in grandiose manner.
** That, or the servants weren't smart enough to figure that out.
* ArbitrarySkepticism: Sure, Natsume believes in spirits, but not fairies. Fairies couldn't ''possibly'' exist.
* ArmorPiercingQuestion: "Which is more important to you? Humans or youkai?"
* ArsonMurderAndJaywalking: Reiko's challenges to the youkai vary from battle duels to rock-paper-scissors.
* [[TheyReallyDoLoveEachOther Aww, Look! They Really Do Care For Each Other]]: A non-romantic example though not fully a VitriolicBestBuds, the two do really care about each other. Specifically examples include where [[spoiler: Nyanko-sensei saves Natsume from a group of masked-youkai, fully claiming his responsibility of being his bodyguard]]. In the anime [[spoiler: Natsume shields Nyanko-sensei from Matoba's dagger, even with Matoba reminding Natsume the possibility of Nyanko-sensei using Natsume]]. Not that it started off that way nor will either two admit it directly.
* AuthorAppeal[=/=]SignatureStyle: partially covered faces. The more human(oid) a particular youkai looks, the higher is the chance that is would have its face partially or completely covered most of the time. Benio, Hinoe, Hiiragi, Tsubame, and several others have something ( butterfly / hair / Noh mask / veil / etc. ) covering part or whole of their face. Even Natsume does this to pass off as a youkai.
* ABoyAndHisX: Supposedly and probably initially an exploited trope, according to Natsume and Nyanko-sensei, but eventually played straight. Not that [[{{Tsundere}} Natsume or Nyanko-sensei would admit it.]]
* ASharedSuffering: Natsume and Natori.
* BecauseYouWereNiceToMe: The Fujiwaras were the only guardians who ever ''wanted'' Natsume to live with them. [[spoiler:And it's this that pulls Natsume off the brink of the DespairEventHorizon and gives him enough courage to fight back against the Ayakashi that wanted to make him its "pet".]]
* {{Bishonen}}: A number of the male characters, but actor and part time exorcist Natori really plays it up, complete with the rosepetal motifs and [[BishieSparkle bishie sparklies]]. In his own words, he can't ''help'' being fabulous.
** Our hero Takashi is Bishonen enough on his own, looking almost ''exactly'' like his grandmother did at his age but with short hair and, obviously, no breasts. Especially when he's returning a spirit's name, and he has a slip of paper in his mouth, and his hair is [[{{Squee}} fluttering in the wind...]]
** And the long eyelashes, don't forget those.
* BishieSparkle: Actor and part time exterminator Natori gets at least one parody of this in almost every episode he appears. Natsume and Nyanko-Sensei like to mock him for this.
** And let's not forget that scene in [[http://i59.photobucket.com/albums/g315/roleplaygirl99/godonlyknows.jpg episode two of ''Zoku''...]]
* BigDamnHeroes: Many characters in the series pull this off but mostly Madara, who usually arrives just in time to save Natsume when he gets in over his head.
* BiggerOnTheInside: The Omibashira mansion which also rearranges itself [[spoiler: to prevent guests from escaping]].
* BitterSweetEnding: Several episodes, notably [[spoiler: episode two, where the shrine "god"'s last worshiper dies, and he vanishes along with her, only to meet her immediately in the afterlife, and finally speak with her. Natsume even offers to take her place, but the spirit claims that won't work "[[TearJerker because you and I are friends]]".]]
** [[spoiler: In the manga, the two don't meet in the afterlife. Instead, the "god" simply disappears, though Natsume does say that he hopes the two of them saw each other again.]]
** Also, any episode dealing with a broken bond between a Human and Youkai. Because, you know, they don't all hate each other. The staggering briefness of a human's life in comparison to that of a youkai is a point of interest, scorn, and even heartbreak amongst them.
* BodySnatcher: One or two get their hands on Natsume. There's also the mask youkai in chapters 53 and 54.
* BroughtDownToNormal:
** A minor character in one episode could once see the youkai - but at some point, his ability mysteriously vanished, leaving Natsume to wonder whether the same thing might happen to him one day.
*** And then [[spoiler: next season, it temporarily ''does''.]]
** Another example is when one of Natori's colleague's, an exorcist, also mysteriously loses his ability to see youkai. This causes a lot of distress for the shiki, not only because their contracts can no longer be undone but that they could no longer directly communicate with their master, despite how much they want to.
* ButHeSoundsHandsome: Nyanko-sensei (in Madara form) indulges in this when he and Natsume go searching for a black Nyanko-sensei doppelganger. It backfires.
-->'''Madara:''' Have you seen a lovely black cat with a sheaf of papers in his mouth around here?
-->'''Natsume:''' ''"Lovely"?''
-->'''Benio:''' No, but I did see a gluttonous, fat-headed one running towards the Youkai banquet grounds.
* {{Cliffhanger}}: The end of season 2, episode 6.
** Season 3, Episode 6 [[spoiler: leaving Natsume unconscious and at Matoba's mercy.]]
** ''Natsume Yuujinchou Shi'' episode six: The episode revolves around Nyanko sensei's efforts to get Natsume out of a magic jar. Turns out it wasn't just a joke; an ayakashi that intended on taking Natsume in the night so he could be used as an offering to a powerful spirit was the one that tossed it in, and he does eventually 'nab poor Natsume. The episode ends there.
* CastFromHitPoints: Freeing youkai from the Book Of Friends is exhausting business.
** PowerStrainBlackout: Will sometimes faint if the strain is too much.
* CollateralAngst: Doesn't happen often but when it does, Natsume is the recipient or [[SecretKeeper some of Natsume's friends are]].
* ConvenientlyPlacedSharpThing: How Natsume escapes Matoba's shiki for the first time by using a broken cup shards to cut through the paper bindings.
* ConsummateLiar: This trope is overall played with. Natsume grows into this when he realizes in his childhood [[CassandraTruth that nobody can see or hear ayakashi]], lying in order to cover any incidents caused by ayakashi and even personal problems. Natori feels that he can relate to Natsume as [[ASharedSuffering he went through similar ordeals]], offering a place to stay "if he ever got tired of lying". In more recent chapters, Natsume has learned to talk to others about his problems though time to time, he still can't always tell the complete truth.
* ContrivedCoincidence: Many years ago, Reiko befriended a young boy who lived in the same neighborhood as she did. She even exorcises a malicious spirit from his house. Said boy was [[spoiler: Shigeru, the adopted father of her grandson Natsume]] and the house became inhabited by the same evil spirit again, leaving Reiko's grandson to finish the job.
* CornerOfWoe: Natsume does [[ItMakesSenseInContext in the jar's non-existent corner]] when thinks about the possible aftermath if his foster parents never found out where he went.
* CreepyChild: Natsume and Reiko were considered this while growing up.
* CrouchingMoronHiddenBadass: Nyanko sensei. It's subverted though. You know almost right off the bat that his somewhat laughable cat form isn't the real him and that he's an extremely powerful ayakashi.
* CuteMonsterGirl: While most Youkai resemble inhuman or {{Gonk}}ish monsters, there's a number of youkai that instead resemble PettingZooPeople or attractive individuals wearing masks. There's a couple of {{Bishonen}} among them, but many of them are female.
* TheDarkArts: Chapter 62 reveals, while not all of it is are necessarily evil, there are a few spells and practices that exorcists deem as illegal. For example:
** a contract between an human and youkai [[spoiler: using the real name of the youkai. Instead, a new name is given until the end of the partnership]]. The reason is that using [[spoiler: a youkai's real name]] will bind its life and fate [[spoiler: to the contract medium]]. Therefore, [[spoiler: the Book of Friends]] would also be considered illegal since it's a collection of these contracts but the existence is unknown to most humans.
** spells that allow [[spoiler: relatively normal people to see youkai]]
* DarkIsNotEvil: A few of the ayakashi seem ObviouslyEvil at first but end up averting it. Special mention goes to season three episode two's [[WoobieOfTheWeek focus guest character]] and Misuzu, who seems intimidating and callous at first but proves to be very much on Natsume's side.
* DeathbringerTheAdorable: [[http://i59.photobucket.com/albums/g315/roleplaygirl99/deathrbingertheadorable.jpg This little guy]]. (Actually a Youkai possessing a snow-bunny Natsume made). D'awwww!
** And then of course [[http://i59.photobucket.com/albums/g315/roleplaygirl99/deathbringersorta.jpg he transforms]]. Cue [[{{Bishonen}} Gen Fangirls]].
* DeceasedParentsAreTheBest: Zig-zagged. While he does love them dearly and some his previous foster parents were [[AbusiveParents not]]-[[ParentalNeglect so]]-pleasant, [[HappilyAdopted he is pretty happy living with]] [[GoodParents the Fujiwaras]]
* DespairEventHorizon: Natsume was on the border of one before he was taken in by the Fujiwaras, [[spoiler:nearly resigning himself to become the pet of one of the many Youkai that stalked him because he felt like he had nowhere else he could go.]]
* DressingAsTheEnemy: Occasionally, Natsume needs to dress up as a youkai to find more information about or to just enter their premises. Natori and once Tanuma as well.
* ExpectingSomeoneTaller: One Ayakashi's [[http://static.tvtropes.org/pmwiki/pub/images/expectingsomeonetallerandfemale_3772.jpg a bit disappointed]] to learn that Natsume doesn't match [[strike:her]] [[MistakenIdentity his grandmother]]'s reputation
* FantasticRacism: The antagonistic Matoba clan holds the Youkai to be creatures inherently inferior to humans, believing they possess no emotion or empathy and are thus [[DoesThisRemindYouOfAnything meant to be in human service]]. The context is upped in season 4, where the Matoba's aggressively hunt a tribal clan of monkey youkai (wearing tribal masks and brandishing spears, no less) who openly wonder what they ever did to humans to deserve this treatment. Matoba is later seen punishing one of them for the "crime" of entering a human home.
* FestivalEpisode: the final episode of the first season, and a few lower-key ones after that.
* FireForgedFriends: A downplayed version but could be described about the relationship with Natori and Madara.
* FlashBack: Natsume gets a few, usually to childhood events. When he returns a youkai's name to them, it's accompanied by a Flashback to the event during which they lost their name to Reiko in the first place.
* FlashBackEcho: While this series is generally a SliceOfLife, there will occasionally be arcs that are a few chapters long or special overarching plot chapters that tend to pop up. Usually, the next normal SliceOfLife chapter will reference at one point certain a quote from the most recent arc that, depending how he takes it, will shape Natsume's character. This pattern is more noticeable in the later half of the series.
* {{Foil}}: Reiko and Natsume, Natori and Natsume, Matoba and Natsume, Natori and Matoba... in fact, any human dealing constantly with youkai are this for each other.
* {{Foreshadowing}}: In episode eight of the first series, Natsume thinks on how horrible it would be to suddenly not be able to see youkai any longer - and surprises himself when he realizes how much he means it, when he's spent all his life wishing [[IJustWantToBeNormal to be ordinary]]. [[spoiler:This makes it all the worse in the sequel series when he actually ''does'' lose his ability.]]
* [[FoodAsBribe Food as a Bribe]]: How Natsume often gets Madara to help him out with different problems.
* FuroScene: Usually provided by Natsume.
* GeometricMagic: Natsume can call forth youkai in the book of friends that he's seen and knows the name by drawing a magic circle, have a mirror, and giving a part of himself (blood would do).
** Natori has magic circle patterns he uses in exorcising.
** Taki has a magic circle pattern, passed down from her grandfather, that allows youkai to be seen by anyone.
* GodsNeedPrayerBadly: the second chapter of the manga has a local spirit who is greatly reduced in power because hardly anybody believes in him any more, and dies when his last sincere worshipper does. (Interestingly, Natsume can't help with this, because it needs to be worship as a god rather than mere belief that the spirit exists.)
* GoldfishScoopingGame: Played by the fox child and Natsume in the anime, during the FestivalEpisode.
* GoodParents: Not just the Fujiwaras, but presumably Natsume's actual parents too. A lot of his [[AbusiveParents guardians in between]] though...
* GottaCatchThemAll: Inverted. Natsume is trying to free any youkai bound to his grandma's book.
* GratuitousEnglish: Nishimura saying "INTERNATIONAL" when both [[ThoseTwoGuys he and Kitamoto]] thought Natsume knew a foreigner girl (though it was a youkai). Another time when Nyanko-sensei is wandering the school grounds, singing "want you" part in english when Taki repeats that line in is a creepy, seductive voice before grabbing him. All instances were PlayedForLaughs.
* HellishPupils: Natsume, his grandmother, and 80% of youkai have these.
* HeroismIncentive: First subverted, then played straight. When Natori initially offers Natsume to become an apprentice, Natori informs him that the pay is good but Natsume still refuses. In another encounter however, Natsume jumps on the opportunity when Natori asks the sealing of a youkai has good reward pay.
* HeyItsThatVoice: [[Creator/HiroshiKamiya Natsume]] has [[Manga/{{Noragami}} appeared]] [[Manga/AttackOnTitan in]] [[Manga/SayonaraZetsubouSensei quite]] [[Main/ArakawaUnderTheBridge a]] [[Manga/BlueExorcist few]] [[Manga/OnePiece other]] [[LightNovel/{{Durarara}} series]].
* HumansAreBastards: a few youkai are of this opinion, and many have good reason to be, but it's not by and by the rule. The anime is far from leaning in favour of this trope alone. It also shows that humans can be [[HumansAreSpecial pretty awesome sometimes, too]] and many Youkai either have a fascination with them, just don't find them all that interesting, or want to make a tasty snack out of them.
* IdiotCrows: Joked with in episode 11 of series one, where Nyanko-Sensei yells at the crows not to call him an idiot.
* IfItsYouItsOkay: Hinoe's solution to the whole StupidSexyFlanders situation with Natsume.
-->'''Hinoe:''' If I just don't think of you as a boy, there's no problem.
* InLoveWithTheMark: Chapters 37 and 37 deal with a starving Ayakashi that took human form so that she could eat a human, only to end up falling for him instead.
* InterspeciesRomance: Several between youkai and humans.
* InvisibleToNormals: the youkai are invisible to most people in the series, with the odd exception.
* IKnowYourTrueName: Requirement in order to control or release an youkai from the Book of Friends.
* ISeeDeadPeople: Sorta. Depends on whether the youkai count.
* ISeeThemToo: Natsume's meeting with Natori has this result. Natsume also asks Tanuma whether he can see the youkai standing on the school field - Tanuma claims he can't - but he does see a vague shadow of their presence.
* IWantMyBelovedToBeHappy: One youkai's human love can no longer see her and has since grown to fall for another, human woman - the youkai is only glad that he has found someone to love again and isn't lonely anymore.
* IWasJustPassingThrough: Nyanko-sensei often insists that he's serving as Natsume's bodyguard so that ''he'' can have the Book of Friends once Natsume bites it. Given that he has yet to give a clear answer as to [[WhyDontYouJustSHootHim why he doesn't just eat Natsume and take the book, it's probably just an excuse.]]
[[/folder]]

[[folder:K-Z]]
* KidsAreCruel: Many children shunned and rejected Natsume through his childhood because he openly told people that he could see ayakashi at the time. When he'd learned his lesson, the damage had already been done. Many kids laughed at him. In season 2, you learn that some children even followed him home and threw rocks at him as a sick game of ''make-fun-of-the-weird-kid.''
* KillingIntent: Some of the youkai. [[Lampshaded Detected]] on their second encounters by Natori from [[spoiler: Kai]] and Matoba from Madara.
* {{Kimodameshi}}: The "Test of Courage" occurred in one episode - of course, this being Natsume Yuujinchou, it's obvious what ended up happening.
* LastNameBasis: The only people who address Natsume by his first name, Takashi, are the Fujiwaras. He and his friends all call each other by last name, with or without an honorific.
* LeftHanging: Mostly related to Reiko. Who was Reiko's baby-daddy? Why is she ''always'' seen in her high school uniform in a youkai's flashbacks? Why did she never actually ''use'' the book of friends? There are hinted to be answers to these questions, but fifteen volumes into the manga, we still have not gotten them.
** And: Could Takashi's mother see youkai? Who or what killed Takashi's parents?
** Maybe to a lesser extent but how and who sealed Madara in the first place?
* MayflyDecemberRomance: any relationship between youkai and human is doomed to end this way, it seems, because of the human's short lifespan in comparison to a youkai's.
** Notably averted with Shibata (human) and Murasaki (youkai). It was Murasaki who was about to disappear. There was also a firefly youkai who died before the human she loved.
*** Although youkai have the potential to live for centuries, death for them can be quite sudden when it does come.
* MeaningfulEcho: Natori calls Natsume "a nice kid... just a nice kid" not long after their first meeting. It turns out this is exacty the same thing a youkai once said to Natori himself, when he helped her as a child.
* MementoMacGuffin: The Book Of Friends is one for Natsume of his grandmother, who had the same ability to see youkai. The MacGuffin part is more for the youkai who seek to possesses it for power.
* MentorMascot: Nyanko-sensei handily manages both of these at once...with minimal MagicalGirl vibes, at that.
* TheMindIsAPlaythingOfTheBody: What Nyanko-sensei claims is responsible for his more cat-like tendencies.
* MoralityPet: Ironically, Natsume is more Nyanko-sensei's.
* NeckLift: Natsume is often subjectated to this by youkai though he usually does manage to [[SoulPower slip through it]].
* NoHuggingNoKissing: [[WordOfGod Yuki Midorikawa]] says that ''Natsume Yuujinchou'' was born out of her desire to write a supernatural story without a noticeable romantic element (something her [[ExecutiveMeddling editor pushed her to add to her previous manga]]). Even the occasional romance between minor one-shot characters are rather subdued and low-key.
* NoSocialSkills: While Natsume is perfectly fine at being polite (he thought if he wasn't, people would have yet another reason to throw him out of their house), but he's terrible at actually developing friendships with other people and has problems sharing his concerns with anyone, even if he logically knows that he really should.
-->'''Natsume:''' Iím sorry, Tanuma. I ''know'' that you and Taki will listen to me, but Iíve never talked to anyone about this stuff before. No oneís ever listened to me before... I ''donít know'' how to talk about it.
** In fact, those who are able to see or sense ayakashi have somewhat poor social skills. This includes Matoba, who seems to have NoSenseOfPersonalSpace in the anime.
* NotWhatItLooksLike: To his intense embarrassment, Touko once walked in on a half-dressed Natsume while he was examining a youkai-made mark on his chest in the bathroom mirror. She thinks he's doing something else.
-->'''Touko:''' Well, you ''are'' that age...
* ObviouslyEvil: A few youkai, although some of them simply lack morals as opposed to being truly malevolent.
* OddlyNamedSequel: The second season prefixed ''Zoku'' (続), meaning "continued", to the title, making it ''Zoku Natsume Yuuijichou''.
** Note that ''zoku'' spelled with a different kanji (族) can [[http://en.wikipedia.org/wiki/Zoku also mean]] "family" of a non-genetic nature, like TrueCompanions. This has a lot of significance to Natsume since it's what he gained throughout the course of the series.
* {{Onmyodo}}: Taki's ancestors used to be this though they currently stopped practicing.
* OnlySixFaces: The manga falls victim to this (Natsume and Nishimura could be twins). The anime, less so.
* OutOfCharacterAlert: Played straight and possibly invoked by Nyanko-sensei when he talks to Tanuma [[spoiler: while impersonates Natsume]]. While the others did notice he wasn't his usual self, they assumed Natsume just wasn't feeling well. [[SecretKeeper Tanuma]] does catch on and does manage to make him reveal himself, much to Natsume's dismay.
* PaperTalisman: Commonly used by exorcists like Natori and Matoba. The Eastern Forest was initially covered in them to prevent the youkai and, unintentionally, Natsume from escaping. Reiko carries [[BatterUp a bat]] covered with them.
* PaperThinDisguise: Well, there's Natori's [[PurelyAestheticGlasses exorcist]] [[NiceHat "disguise"]] for starters... sometimes even managing to forgo the hat and still not get recognized by passerby. Not only that, but when humans want to blend in with youkai, their most drastic measure usually is to just cover their eyes with a literal [[PaperThinDisguise paper-thin mask]] of some sort. Might be slightly justified in the latter case though, given the nature of {{youkai}}.
* ParentalSubstitute: The Fujwaras are this for Takashi. Already in high school, and this is the [[TheWoobie first time he has felt like he is part of a real family.]]
** Meanwhile Natori straddles an uncomfortably thin line between this and HoYay.
* PettingZooPeople: Many of the Youkai, including the adorable little fox boy.
* PeopleJars: Natsume temporarily gets stuck in one though it might also be used on youkai as well. While it was first just [[PlayedForLaughs fun and games]], [[spoiler: [[MoodWhiplash things take a turn]] when Natsume gets taken away with the purpose to be given as an offering which leads to another set of events]].
* RememberThatYouTrustMe: Years of {{Cassandra Truth}}s and bullying means that Natsume tends to be secretive even with people he ''knows'' he can trust. In his words, he's never really learned how not to.
* RightBehindMe: Nyanko-sensei actually ''joins in'' on the Nyanko-sensei bashing before the other Youkai actually realize that he can hear them.
** One time, Natori catches Natsume and Madara laughing at his one of his [[{{Bishounen}} sparkling]] commercials from behind. In the manga, Natori then mockingly teases them by using the same line from the commercial on them, much to their dismay.
* SailorFuku: Inverted in that this is their high school uniform while the more professional-looking ones were seen more in middle school though this might be because the main story takes place in a more rural part of Japan.
* {{Scapegoat}}: Flashbacks showed Natsume often had to [[SilentScapegoat act as one]] by taking the blame when the youkai caused vandalism because [[CassandraTruth years of experience showed there was no way to prove otherwise]]. There is also a cup youkai who acted as one to [[spoiler: prevent Natsume's arm being bitten off]] by taking on the misfortune on itself and dying.
* SealedEvilInACan: Some of the youkai are usually seal in certain mediums like special pots, mirrors, etc. However, whether the sealed youkai is evil or not varies ([[BigBad though it is never taken to the extremes]]).
* SecretTestOfCharacter: Turns out that [[spoiler: Natsume being marked with the Five Day Curse from a particuarly vicious spirit was orchestrated by one of his own contracted youkai, who wanted to test Natsume to see whether he was worthy of holding onto his name.]]
* SliceOfLife: This show's secondary theme, alongside the supernatural.
* SleepModeSize: Nyanko-sensei's Lucky Cat form
* SnowballFight: Episode two of ''Zoku''.
* SoulPower: With varying amount of it. People with enough spiritual power can see, hear, and touch {{youkai}}, and can do things like seal evil spirits, perform exorcisms, and punch youkai clear across a room; they can also hear what Nyanko-sensei is actually saying, instead of it sounding like he's just meowing. Those with just a little spiritual power can hear Nyanko-sensei, but not do any of the other things. Also, there are some cases where people with strong senses losing their power when they get old.
* StockFootage: Natsume's method of returning the spirits names to them, (it's really a rather pretty piece of stock).
* StupidSexyFlanders: Besides the incident mentioned in AttractiveBentGender, Natsume's managed to fluster ''Hinoe'' with a smile.
-->'''Hinoe:''' Dammit, why do you have to be a ''man?''
* SubordinateExcuse: Implied to be why Hiiragi becomes one of Natori's Ayakashi servants.
* TakingTheBullet: Sorta. In chapter 26 [[spoiler:Natsume takes an arrow for Nyanko-sensei]] although it kind of doesn't live up to its merit as [[spoiler:the next one hits and disables Nyanko-sensei for several days]]. And in the anime, [[spoiler: Matoba manages to hit both of them with ''one'' arrow]].
* TheOnlyOneAllowedToDefeatYou: One of Nyanko-Senseis several explanations for not letting the Ayakashi get to Natsume is because Natsume promsied Nyanko-sensei the Book of Friends upon his death - he regularly calls Natsume "His Prey" - and no one else's.
* ThirteenIsUnlucky: Taki's curse included having the last 13 people who she called by name to be killed, which Nyanko comments to be a merciless number.
* ThoseTwoGuys: Kitamoto and Nishimura like whoa. Although they do get ''way'' more screen time and focus than most examples; a good deal more than [[SecretKeeper Taki and Tanuma]], in fact, despite being unaware of Natsume's abilities. Just not much character development other than being friendly, hilarious, and Nishimura has a crush on Taki.
** Though they did [[spoiler: teach Natsume how to ride a bike]] part way through the story.
** They now have their own focus chapters--chapter 51.1 (Nishimura) and chapter 51.2 (Kitamoto). These detail how they each met Natsume and became friends with him through unsuspected encounters with youkai, and a little on their home lives and families.
** There's also a youkai example with the cyclops and bull youkai. They get a well-above-average amount of focus as well.
* ThereAreNoPsychiatrists: In this case, a ''good'' thing; as a child, Takashi's caretakers tended to think of him as a liar who misbehaved to get attention and gave up on him, rather than sending him to get therapy which he didn't need since the things that he saw were real.
* ThreeAmigos: Natsume, Taki, and Tanuma, once Natsume properly introduces them to each other.
* {{Tsundere}}: Hinoe has her moments. Also Madara and Natsume to each other. Don't EVER try to point out the fact that they get along well, or BOTH of them will deny, deny, deny.
* TwelveEpisodeAnime: Thirteen episodes, all four seasons.
* UnfinishedBusiness: Depsite not ''quite'' being ghosts, a lot of Youkai seem to have some particular task they're desperate to complete before they move onto the next world. Many seek Natsume out to do this.
* UnsettlingGenderReveal: Hinoe, who ''really'' liked Reiko, gets as far as groping Natsume's chest before it dawns on her that he's actually her IdenticalGrandson. [[DoesNotLikeMen She is not pleased.]]
-->'''Hinoe:''' ...''Where are your boobs?''
* VillainTakesAnInterest: Matoba in Natsume and Nyanko-Sensei. Nanase does this initially with Natsume and Reiko though to a much lesser extent.
* WeCanRuleTogether: Downplayed as Matoba offered Natsume twice to join his clan and that Matoba [[WellIntentionedExtremist isn't an outright villain]]. However, he is a lot more casual compared to other examples of this trope because he has [[{{Blackmail}} other ways of getting Natsume to work with him]].
* WhiteMaskOfDoom: Many youkai wear them, some more closer to CoolMask, though not all of them are evil. The Matoba clan's artificial youkai wear them that are made of paper but are powered through malevolent intentions.
* TheWorfEffect: The Matoba clan and Matoba himself quickly establish themselves as to not be fucked around with by being able to not only cause serious damage to Nyanko-Sensei in his Madara form, but knock him out of it altogether.
* YouAreNotAlone: Most of both series' deal with Natume steadily working this out, one TearJerker at a time.
** Natsume says this outright to Gen, during [[http://www.youtube.com/watch?v=fX9ZOGVOsL8&NR=1 this episode]].
* YouCanSeeMe: Many youkai are often highly surprised when a human does just that.
* YouHaveOutlivedYourUsefulness: Seems to be the Matoba clan's philosophy in regards to youkai (and sometimes humans if they get in the way).
* {{Youkai}}: Well, obviously...
* YouGottaHaveBlueHair: Both averted (with humans, a rare anime example) and justified (with youkai). None of the human character's hair colour is improbable (Natsume's and Reiko's grey hair in the manga, though really rare, is still possible). Any odd coloured hair characters are likely from youkai (Misuru's lavender hair, Hinoe's blue hair, etc).
