The characters for the manga and anime ''Manga/NatsumesBookOfFriends''.

!!Main Characters

[[folder:Natsume Takashi]]

-->'''Voiced by:''' Creator/HiroshiKamiya
* AccidentalMisnaming: When Madara is flustered or panicked, expect him to be called a variety of things: My prey! My servant! My snack! My meal! and so on.
* AbusiveParents: Some of his previous foster parents 'got drunk and hit him', and others 'forgot' to feed him. Natsume dismally blames himself for their behavior. They always [[BreakTheCutie started out nice]].
* AdaptationDyeJob: Like his grandmother, has white hair and [[GrayEyes silver eyes]] in the manga.
* AllLovingHero: He cares greatly for both human and youkai. In contrast to his [[HatesEveryoneEqually grandmother Reiko]] and the exorcists like [[WellIntentionedExtremist Matoba]].
* ApologeticAttacker: Has his moments.
* AllOfTheOtherReindeer: Was bullied when he was a child due to his ability.
* AttractiveBentGender: Though it's not really an outright gender bend, Natsume just gets possessed by a Youkai who happens to be female, and who occasionally slips to the surface causing him to to exhibit feminine qualities (sometimes seemingly having longer hair). All of his friends start finding themselves [[StupidSexyFlanders disturbingly attracted to him]].
* BigBrotherInstinct: Although brief, he has this for the little fox youkai and Kai.
* {{Bishonen}}: [[ThoseTwoGuys Nishimura and Kitamoto]] lampshade this about him in chapter 11. Not surprising though since looks almost exactly like his grandmother as noted by other youkai.
* BreakTheCutie: The story of his childhood.
* BystanderSyndrome: While not being an outright jerk, Natsume had started the series with giving the cold shoulder to youkai who came to him with a problem (which is understandable [[DespairEventHorizon considering the events that lead to his first meeting of the Fujiwaras]]). However, as he got a better understanding of youkai, that started to change.
* CassandraTruth: This happened a lot during his childhood.
* ChickMagnet:
** Proves to be this in episode 35 where he was one of the bazaar workers. He attracted a lot of female customers.
** When he first transferred to his current school, it's pointed out that he was a hot topic among the girls.
** In episode 5 of Shi, Yuriko mentions that the girls in his class thought of him as "cool and calm".
* ChronicHeroSyndrome: Gradually develops into this. Though he used to help youkai reluctantly, Natsume will rush headlong toward Youkai, and all kinds of other danger if he knows someone is in trouble, knowing full well that his opponents are more often than not ''much'' stronger than him.
* ClassicalAntiHero: He's an ordinary human minus the ability to see youkai, and is filled with self-doubt and trust issues.
* ConsummateLiar: [[ZigZaggingTrope Zig-Zagged]]. Natsume would usually have to lie in order to cover incidents created by youkai because years CassandraTruth during his childhood taught him [[JustifiedTrope no human would believe him]]. However, thanks to the help of Fujiwaras and his friends, he has learned to open up to people and has even found others who [[SecretKeeper he can talk about his problems]]. Because of this, in more recent chapters, people who are close to him can now tell if he is lying or hiding the truth (secretkeeper or not) though they don't always choose to voice it. For the most part
* ConvenientlySeated: Natsume sits in a seat by the window between his friends, Kitamoto and Nishimura. This gives him a view to see if there is anything (or anyone) strange nearby. Inconveniently, it also allows to be more easily startled if something does pop up.
* CurtainsMatchTheWindow: Natsume is a blond with gold eyes. Somewhat averted in the manga, where the eyes are more green than silver.
* CutenessProximity: A mild example, but Nyanko-sensei calls him out on it once, saying he's far too nice to youkai he thought were cute.
* DeathGlare:
** Parodied: Natsume's sometimes give this look with often Nishimura and Kitamoto unintentionally at the receiving end, usually after dealing with youkai. Played straight during the school festival in chapter 26 when he initially suspects they are possessed. However, in more recent chapters, they now assume he just not feeling well.
* DeadpanSnarker: Though only to Nyanko-sensei and Natori. It has died down the later but still tends to amp up the snark around whenever the situation calls for it.
* DidYouJustPunchOutCthulhu: He frequently knocks out strong youkai with a punch, the most frequent victim being Madara. It's useless against humans though, since it's his SoulPower which does all the work, rather than his physical strength.
* DistressedDude: Natsume has the bad habit of getting captured frequently. For instance, in episode 5 of season three, he gets captured by an ayakashi that's intent on cutting off his arm so that it can use it to retrieve its lost head. Natsume's friends are left frantically searching the house for him. He's also been kidnapped by Matoba two or three times. Nyanko-sensei usually bails him out when he doesn't get out himself.
* DraggedIntoDrag: In one of the drama CD's he's forced to play the part of a girl in one of Natori's dramas.
* DudeLooksLikeALady:
** And so he tries to act manly and uses masculine speech, according to WordOfGod.
** The following exchange near the end of the second season highlights on it:
--->'''Kai:''' ...Sorry for calling you a sprout, a chopping board, and a girly boy...
--->'''Natsume:''' Ah, w-well, i-it's okay...
--->'''Tanuma, Taki & Sensei:''' (suppressed snorts & laughter)
--->'''Natsume:''' ...''Notamusing!''
--->'''Trio:''' (guilty, somber, not meeting one another's eyes) ...Right!
** When Natsume shows his friends his parents photo, they compared him to his ''mother'' at instant, not father.
* DudeWheresMyRespect: Despite his young age, he has an incredible amount of spiritual power, but whenever he goes to exorcist gatherings with Matoba, he's forced to hide his identity and pretend to be a youkai servant. Because of this, most other exorcists are oblivious to his talents and treat him like a lackey.
* HairOfGoldHeartOfGold: In the anime, and a rare male example.
* HappilyAdopted: By the Fujiwaras.
* HeroicSelfDeprecation: He considers himself an inconvenience to the people around him, and considers even simply asking for help with something to be a selfish indulgence.
* FearOfThunder: [[InformedFlaw According to Nyanko-sensei]].
* FriendlessBackground: When he was a kid his frequent outbursts caused the other children to become frightened of him and bully him, and he never got close with anyone.
* TheHero
* IdenticalGrandson: Natsume Takashi looks a ''lot'' like his grandmother Reiko, original owner of the Book of Friends. and since many (if not all, Hinoe certainly seems to express a preference) Youkai don't really care too much about gender, Natsume tends to get Youkai who are looking for his ''grandmother'' on his tail.
** Taken to it's logical conclusion when someone calls Natsume "Girly Man".
* IDidntTellYouBecauseYoudBeUnhappy
* IJustWantToBeNormal: At first. [[spoiler: He grows out of it later.]]
* IJustWantToHaveFriends: All he ever wanted was someone to understand him. He briefly had a friend who he thought was like him, but she was really another youkai.
* IllBoy: It was hinted that he has anemia, though this is likely a cover for how much interacting with youkai can drain a person's energy.
* ISeeDeadPeople: Depends if youkai count.
* InTouchWithHisFeminineSide: Despite what it says in [[DudeLooksLikeALady Dude Looks Like A Lady]] above, it's not all that hard to get this impression.
* LastNameBasis: Almost no one calls him by his birth name Takashi with the exception of [[FirstNameBasis his biological and current foster parents]]. In stark comparison, his grandmother is referred to by her first name by pretty much everyone.
* LonerTurnedFriend: Thanks to Nishimura who had formally introduced him to Kitamoto.
* MagneticMedium
* MoralityPet: Sort of one for Madara/Nyanko-sensei.
* MysticalWhiteHair: In the manga, [[IdenticalGrandson like his grandmother]], though was often treated [[WhiteHairBlackHeart otherwise]].
* NiceGuy
* NoSocialSkills: Justified, given his FriendlessBackground.
* NotGoodWithPeople: While his ability made it hard to talk to people in general, this seems especially with children.
* OrphansOrdeal: A good bit of Natsume's difficulty with people (and his reluctance to tell the Fujiwaras about his abilities) stems from the fact that, up until then, he was passed around from relative to relative because nobody wanted to deal with the CreepyChild that kept telling "lies" about [[ISeeDeadPeople seeing ghosts and Youkai]].
** AbusiveParents: Chapter 31 confirms that several of the parents he's lived with were physically or emotionally abusive.
** ParentalNeglect: Also confirmed in the aforementioned chapter that some of Natsume's parents also forgot to feed him as well.
* PapaWolf: He develops this for Tama. He refuses to hand him over when confronted by Isozuki and was willing to die to protect the little creature he cared for.
* ParentalAbandonment: Natsume's parents are dead, and every single family he's lived with before the Fujiwara's looked forward to the day he left their family, since he could [[ISeeDeadPeople see spirits.]]
* PlotMagnet: Both because of his powers and because his connection to Reiko.
* PsychicPowers
* PowerIncontinence: Due to how powerful he is, his spiritual power sometimes leaks out into inanimate things without him being aware of it. On two occasions, he has created vessels (a snow bunny and a mini clay cat respectively) which both got inhabited by powerful spirits. Another time, he re-animated a small man-made youkai from the scraps of special paper that got attached to his clothing.
* TheQuietOne: What first impressions of him often are.
* RuleOfEmpathy: He's driven to help humans and Youkai alike, even if they don't want or deserve his assistance, [[NotYourProblem much to Madara's chagrin]].
* SilentScapegoat: Natsume often wound up as one in his adolescence, when Ayakashi started causing acts of vandalism around him; his options were either to let everyone believe he was some sort of delinquent, or let them believe he was some sort of ''crazy'' delinquent.
* SociallyAwkwardHero: He was unable to make any friends as a child because of the discovery of his connection to spirits. He's slowly growing out of this, though.
* SoulPower: He has a lot of spiritual power, which is the reason behind all of the other supernatural tropes that apply to him, including his ability to [[PunchedAcrossTheRoom punch youkai clear across a room]].
* StepfordSmiler: Lampshaded by Nishimura.
-->'''Nishimura:''' ''It felt like that was the first time I saw the ever smiling transfer student smile. But when I looked at it another way, I thought to myself that his normal smiles must all be fake.''
** [[WhenSheSmiles When He Smiles]]: How Nishimura discovered this when Natsume did gave an genuine smile.
* SupernaturallyDeliciousAndNutritious: Youkai generally find him delicious due to his strong spiritual power.
* SupernaturalGoldEyes: Has considerably strong psychic powers. However, his eyes are green/grey in the manga.
* WeirdnessMagnet

[[caption-width-right:350:[[labelnote:Click here to see Madara's true form.]][[quoteright:325:]][[/labelnote]]]]
-->'''Voiced by:''' Creator/KazuhikoInoue

* AccidentalMisnaming: Nobody besides Natsume bothers to get Nyanko-sensei's name right.
** Giving us such gems as Nyan-Nyan Sensei, Nyankichi-kun, Nyangoro, Kitty, Cat-Dumpling, Tanuki, etc. Tanuma eschews trying to remember it altogether, and just calls him Ponta.
** In the manga, Natsume usually just referred to him as "cat" in the early chapters. His anime self is a little more respectful though. A little.
* TheAlcoholic: Really likes to drink sake in his spare time.
* AmplifiedAnimalAptitude: Downplayed but Nyanko-sensei seems to be really good with his fingers/paws in cat form. For example, he can hold chopsticks, hold teacups, reading the economic section of the newspaper, etc (though he still relies on Natsume for opening cans and such).
* AttentionDeficitOohShiny: Gets frequently distracted in his cat-form, often mid-sentence.
* BadassBaritone / PowerMakesYourVoiceDeep: Definitely a powerful youkai, and his voice is quite deep when he is in youkai form. However, in his ManekiNeko form (in which his powers are more restricted), his voice sounds a lot more nasal.
* BathtubBonding: He ''loves'' to bathe with Natsume, [[GetOut though Natsume does not]]. Sensei [[TheThingThatWouldNotLeave refuses to get the message]], and eventually Natsume gives up on expecting to get any personal space from him.
* BerserkButton: Seen once when Natsume got shot defending Madara from an arrow by an exorcist.
* BewareTheSillyOnes: Calls himself middle-aged, acts accordingly, and looks nothing near capable of kicking butt, but get him angry and he turns into a...
* BigDamnHeroes: His main role in this series.
* BigEater
* BigEgoHiddenDepths
* BoltOfDivineRetribution: Expect this to happen if you insult Madara's [[CantTakeCriticism singing or make remarks about his weight]].
* BrokeYourArmPunchingOutCthulhu: His power rivals Japanese deities, and while he technically ''can'' defeat them, its still not a fight he's eager to commence, [[DyingCurse because winning will leave him wrecked and cursed]].
* CanisMajor: His true form is a ''huge'' and powerful inugami.
* CatsAreMean
* CreepyGood: Very much on Natsume's side when Matoba darkens the young man's door again. The exorcist tries to blackmail Natsume into helping him. This time however, Madara doesn't even get upset. He just smiles at Matoba throughout, with menacingly yellow glowing eyes, encouraging his retainer to go because "the more exorcists around, the more filling his meal would be".
* DeadpanSnarker
* DeathsHourglass: The human-eating inugami knows when a person is about to die, [[FridgeLogic because they no longer "taste good"]].
* TheDreaded: To low-level Youkai.
* DrowningMySorrows: When he thinks Natsume has replaced him with a real cat that he was temporarily looking after. He gets so drunk and bad-tempered the other Youkai become terrified of him.
* FatCat: To the point when his paws sometimes cause little earthquakes when he walks.
* FluffyDryCat: We get one picture of Natsume blow-drying Nyanko-sensei too long.
* GodsNeedPrayerBadly: ''Inverted''. As an Inugami/Dog God, he's extremely powerful, capable of existing independently without worship.
* {{Gonk}}: Pretty much known to everyone as "Natsume's hideous cat".
** UglyCute: Taki (and probably '''you''') finds him to be ''irresistibly adorable'', and {{glomp}}s him whenever she gets the chance.
* GiantFlyer
* IAmBigBoned: Very insistent that his cat form is ''not'' fat, merely very fluffy.
* IfYouDieICallYourStuff: His relationship with Natsume is formed on this trope. In return for serving as his bodyguard, he gets the Book of Friends after Natsume dies.
* ImAHumanitarian: Natsume [[KidWithTheLeash keeps him on a leash]], but he ''has'' asked on occasion to eat particularly grating humans.
* TheImp
* IntellectualAnimal: Kind of, seeing as most Youkai tend to be at least sentient.
* IAmNotWeasel: Though in this case, a cat.
* JerkWithAHeartOfGold: For all his claims to be a ruthless, cruel and uncaring monster who threatens to eat other youkai or humans on a whim, [[InformedAttribute Madara is astonishingly benign compared to many other youkai that appear in the series]]. The jerk image stayed for a little while to begin with, but is completely shattered when Madara pulls a Ghibli-style rescue on a little girl who fell down a cliff. Wanting the Yuujinchou was definitely one of his most important motives, and even this is called into question when Madara tempted Natsume to drink mermaid blood. Natsume called him out on this, saying if he was immortal, Madara would never get the Yuujinchou, to which Madara lapses into silence.
* JustEatHim: What he has threatened to do to Natsume if the Book of Friends gets any smaller, but his (seemingly rather half-hearted) attempts always fail. He even unintentionally tries to "[[MarshmallowDream sleep eat]]" Natsume on occasion, which yields [[HilarityEnsues similar results]].
** He often forgets the deal he made with Natsume, embellishing it with many small details, such as saying that he's being given permission to ''[[ThisIsMyHuman eat Takashi when he dies]]'' to other rival youkai.
*** When asked by Benio why he doesn't [[TropeNamers just eat Natsume]] and take the book by force, he reveals he's merely killing time and [[WeAreAsMayflies that human lives are terribly short]]. It would be a sad waste to end the fun prematurely, and he'd rather postpone it.
* ManekiNeko: His ShapeshifterDefaultForm.
* MentorMascot: Natsume even address him as [[OldMaster "Sensei"]].
* NobleDemon: Madara continues to insist that he's really nasty and uncaring and only hangs around Natsume because the latter is his prey (or alternatively his servant). He's not really fooling anyone.
* NotSoAboveItAll: Nyanko-sensei regularly brings up his truly awesome powers and the fact that he is "not a fortune cat, damn it!"--until Natsume starts petting him, or waves a toy in front of his face. Or he spots a grasshopper. Or a little girl has fallen down a cliff and needs rescuing.
* NotYourProblem: Tries to convince Takashi of this, but, well, doesn't always work.
* ObfuscatingStupidity: Knows far more about spells, all matters Youkai and half-bloods, than he's willing to tell Natsume.
* PapaWolf: Quite literally, given his true form. ''Don't'' harm Natsume if you know what's good for you.
* [[ParentsForADay Parent For A Day]]: Type 1 in some of the recent chapters and the OVA where he gets stuck taking care of lost kid(s). He's had Hinoue's help in one of the instances and disregarded Natori's and the dog circle youkai in another. Averted in the de-aged chapter where he pushes the responsibility of younger Natsume to Tanuma and Taki's care.
* PowerTattoo: In youkai form, he has a mark on his forehead that [[LightEmUp glows to fend off or exorcise youkai]].
* RealMenHateAffection: Doesn't always take well to Natsume smiling, hugging or embracing him in public.
* RedEyesTakeWarning: When Natsume is almost fatally wounded by Matoba.
* RidiculouslyCuteCritter: In SleepModeSize.
* SarcasticDevotee
* {{Sizeshifter}}: Can change his size at will from barely fitting inside Natsume's bedroom, to being ''as large as a house''.
* SleepModeSize: He's been sealed inside a ManekiNeko for so long that it's effectively become his default form.
* SnarkyNonHumanSidekick
* SoreLoser: He ''hates'' losing games.
* SpiritAdvisor: Kind of.
* SuperWeight: Madara is one of the strongest Youkai shown in the series. He makes claims that he's the best of them all, [[ProveIAmNotBluffing and this may very well be true]].
* TeamPet: Sort of. He's not ''technically'' a pet.
* TheOneThingIDontHateAboutYou: He found Reiko to be deplorable for taking Youkai's names ([[{{Hypocrite}} even though he plans to take said names and build himself an army]]), yet he confesses to Natsume he saw her as a ''very'' attractive human.
* ThisIsMyHuman: He gets incensed whenever other youkai try to possess or take Natsume away from him.
* {{Tsundere}}: He'll never admit that he has a soft spot for Natsume even though it's obvious to others; and when confronted with it, he vehemently denies any such feelings.
* VoluntaryShapeshifting: Can transform into a ManekiNeko, a CanisMajor true form, a girl[[note]]based on Reiko[[/note]], [[InformedAbility an old man]], and Natsume Takashi.
* {{Youkai}}: Obviously. (He appears to be an inugami or some manner of wolf spirit in his true form.)
* YouFool: What he frequently calls Natsume, who goes out of his way to help human and youkai alike at his own expense.
* YouHaveNoIdeaWhoYoureDealingWith: What he frequently warns any foolish low-rank youkai who fail to recognize his true form and power.
** Even Japanese mythological gods/deities don't recognize him as anything other than an "[[OurGodsAreDifferent overgrown beast]]".

[[folder:Natsume Reiko]]
-->'''Voiced by:''' Creator/SanaeKobayashi

* ActionGirl: You know you're one when you can defeat every single ayakashi you come across. Two bullies throw a rock at her and she manages to knock it back ''with a stick'', without flinching or hesitation.
* AdaptationDyeJob: Like her grandson, has [[MysticalWhiteHair white hair]] and [[GrayEyes silver-green eyes]] in the manga.
* BatterUp: Is usually seen [[WeaponOfChoice wielding a baseball bat]] that is often wrapped by [[PaperTalisman talisman]].
* BishieSparkle: Not a stranger to it; see episode 2.
* {{Bishoujo}} (In-Universe): Her beauty is often noted with [[ActionGirl her strength]].
* BrokenBird: Became rather angry and violent thanks to the treatment she's received over the years.
* EvenTheGirlsWantHer: Hinoe's attraction to her is anything but subtle, though slightly subverted as Hinoe DoesNotLikeMen and most non-humans tend to disregard gender.
* FirstNameBasis: How everyone addresses her, possibly to differentiate her from her grandson.
* FriendlessBackground: Even moreso than Natsume.
* GlorySeeker: Probably the reason why she takes the names of the youkai.
* GrinOfAudacity: Especially when challenging a youkai.
* HatesEveryoneEqually: Was said to hate both humans and ayakashi alike.
* PosthumousCharacter: Reiko. Once Natsume has returned the name of a youkai, a flashback is usually shown about the circumstances surrounding when Reiko first took the name.
* MysticalWhiteHair: Only in the manga though, [[IdenticalGrandson like her grandson]], though was often treated [[WhiteHairBlackHeart otherwise]].
* ShroudedInMyth
* StepfordSmiler: She is Type A.
* SugarAndIcePersonality: From what we've seen. Sometimes she comes off as aloof and mysterious, other times understanding and almost warm.
* SupernaturalGoldEyes: Has considerably strong psychic powers. However, her eyes are grey in the manga.

!!The Fujiwaras

[[folder:Fujiwara Touko]]

-->'''Voiced by:''' Creator/MikiIto

* GoodParents: She shows genuine concern for Natsume despite not sharing any blood. She first visits him and offers to take him in despite the rumors about his reputation. She also scolded Natsume when he [[FreeRangeChildren suddenly left the house for a day]] without giving her proper notice.
* HappilyMarried: To Shigeru.
* HiddenDepths: Notes in the special chapters that she had to fight for her and Shigeru's happiness before "peace quietly snuck on them".
* {{Housewife}}: Does the housework and cooking in the family.
* ParentalSubstitute: Natsume's current foster mother.
* MuggleFosterParents: She is unaware about Natsume's ability, though her kindness prevented him from crossing the DespairEventHorizon.

[[folder:Fujiwara Shigeru]]

-->'''Voiced by:''' Eiji Itou

* GoodParents: Open-minded to Natsume's freedoms but scolds him if he crosses the line (like leaving the house all of a sudden without giving a warning)
* HappilyMarried: To Touko.
* ParentalSubstitute
* MuggleFosterParents: He is unaware of Natsume's ability, though it is possible that he might suspect something. His kindness has helped soften Natsume's outlook on life.
* OpenMindedParent: One chapter has Natsume completely wreck a room due to an exorcism spell in order to get rid of youkai that cursed the house. When Shigeru stumbled upon this room, [[FlashBackEcho looking like a very familiar incident of the past]], he lets it slide as he knew Natsume did not purposely try to wreck the house. In later scenes, we do see him being more supportive of Natsume and him being against putting too many limitations on Natsume's freedom.

!!Natsume's Classmates

[[folder:Tanuma Kaname]]

-->'''Voiced by:''' Kazuma Horie

* AffectionateNickname / EmbarrassingNickname: "Kaname-chan" by his aunt. Not necessary embaressing but enough Natsume's friends tease him about it.
* ActionSurvivor: Deconstructed in the Omibashira arc when Tanuma is forced to become this after Natsume is kidnapped to become a meal offering. Despite the strain from being near youkai, he does manage to disguise himself as a one and sneak into the place. He tries to free the real Natsume by making a bluff but almost gets caught and attacked. [[FromBadToWorse Things begin to go downhill from there]]
* DressingAsTheEnemy: For the aforementioned example above.
* IllBoy: He's more vulnerable to the influence of spirits, so he tends to get sick quite easily.
* MissingMom: While we have seen his father on two separate occasions, we have yet to see or hear any mentions about his mother.
* NiceGuy
* NonActionGuy: Due to his illness. Acts more of a more support role for Natsume.
* NotGoodWithPeople: Tanuma also sees Youkai, but worries that he won't be of any use, or will just be a burden on Natsume, because of his weak power - he can only see shadows and glimpses of Youkai.
* ParentsForADay: Platonically type 2 with Taki, they babysit a [[BabyMorphEpisode de-aged]] Natsume for a day.
* PsychicPowers: Can understand Nyanko-sensei, feel the youkai's presence and can sometimes see shadows, can't exactly see their corporeal forms.
* SecretKeeper: Became one when Natsume confirms Tanuma's suspicions about the shadows he sees though Natsume asks he keep it a secret.

[[folder:Taki Tooru]]

-->'''Voiced by:''' Creator/RinaSato

* CutenessProximity: Although her eye for cuteness is called into question when she has this reaction to Nyanko-sensei (who everyone else regards as the cat equivalent to a {{Gonk}}).
* IdenticalGrandson: According to the youkai that knew her grandfather and have confused her for him. However, this might somewhat exaggerated considering that youkai don't recognize gender.
* KindheartedCatLover
* TheQuietOne: At first, but that was only because [[spoiler: an evil youkai cursed her, so that the last thirteen people whose names she says will die. Natsume helps her break it.]] After that, she became more like the GenkiGirl.
* NiceGirl
* NiceHat: In her earlier appearances.
* ParentalAbandonment: Downplayed but most of her family is out of the house: both her brother and father are overseas while her mom often comes late back from work, making Taki feel most closest to her grandfather [[PosthumousCharacter who is dead]].
* ParentsForADay: Platonically type 2 with Tanuma, they babysit a [[BabyMorphEpisode de-aged]] Natsume for a day.
* SecretKeeper: Asked Natsume's help after hearing about his ability from a youkai. Along with Tanuma, she helps Natsume give distractions to his other friends.
* TheSmartGirl: She is very knowledgable of youkai folklore and its relations to the surrounding area, thanks to her grandfather's notes. Despite having the least spiritual aptitude out of the three, she is also the most component as deciphering writings and creating charms as seen in the hotel arc.
* TheSmurfettePrinciple: In the manga, she's Natsume's only close female friend since Sasada moves away.
* WholesomeCrossdresser - Taki has [[ one panel]] of this for a school festival crossdressing cafe, and looks damn good too.
* UnfazedEveryman: One of Natsume's friends who know his secret but doesn't have the ability. She still is quite knowledgeable about them and has encounters by herself, thanks material grandfather left behind. Chapter 64-65 actually explores on the idea if ordinary humans should have contact with the supernatural.

[[folder:Kitamoto Atsushi]]

-->'''Voiced by:''' Hisayoshi Suganuma

* ADayInTheLimelight: Chapter 51.2
* BokeAndTsukkomiRoutine: Occasionally plays the StraightMan to Nishimura, but not constantly.
* ChildhoodFriends: With Nishimura, or at least it seems that way.
* MissingMom: While his mom didn't appear in Kitamoto's special focus chapters, it is mentioned that she is out working since their father is ill.
* NiceGuy: One of Natsume's first friends after moving with the Fujiwaras. Warns him about the violent seniors and tries to protect Natsume twice from some unseen youkai during his special bonus chapters.
* TheCaretaker: Due to his father's illness and his mother working to compensate, he often takes care of his younger sister and father til his mother comes home.
* ThoseTwoGuys: Along with Nishimura, though contrary to the trope, they have fairly important roles in the plot as one of the few (non-psychic) people who are close friends of Natsume. They also get more screentime than anyone other than Natsume and Nyanko-sensei and a fair bit of fleshing out in the manga.

[[folder:Nishimura Satoru]]

-->'''Voiced by:''' Creator/RyoheiKimura

* ADayInTheLimelight: Chapter 51.1
* AloofBigBrother: Revealed to have one in his special focus chapter.
* BokeAndTsukkomiRoutine: Occasionally plays the funny man to Kitamoto, but not constantly.
* ThoseTwoGuys: Along with Kitamoto.
* NiceGuy: Natsume's first real friend, he and Kitamoto really do a lot for him.
* {{Keet}}
* ChildhoodFriends: With Kitamoto.
* ChivalrousPervert: In most series, he would not be considered this. In [[NoHuggingNoKissing such a series as this]], when he is the only one of Natsume's companions who has a crush on somebody and insists that they should have a cafe with bunny girls for the school festival, he comes off as one.
* InnocentlyInsensitive: One of the author's notes in volume 13 states that he gets into conflicts due to this.
* TheMcCoy: Allegedly the most soft-hearted of Natsume's friends.
* [[SiblingYinYang Sibling Ying-Yang]]: Nishimura is more laidback and cheerful while his older brother is more studious and stoic.
* TheUnfavourite: His family is mainly preoccupied with his older brother's studies, going to the point where Nishimura makes his lunches himself.

[[folder:Sasada Jun]]

-->'''Voiced by:''' Creator/MiyukiSawashiro

* AdaptationExpansion: In the original manga (chapter 5), she moved away after the test of courage. In the anime she is still interacting with Natsume after the test of courage.
* AscendedExtra: Left after chapter 5 of the manga, but sticks around in the anime long enough to become part of Natsume's social circle.
* AllLoveIsUnrequited: Is heavily implied to have romantic feelings for Natsume in some of the drama [=CDs=]. Natsume, however, [[ObliviousToLove is completely unaware.]]
* CharacterizationMarchesOn: The first two seasons have her constantly try to get involved in Natsume's youkai dealings. She stops doing this from season 3 onward.
* ClassRepresentative
* DoggedNiceGuy: Non-romantic example in Sasada Jun who's basically trying to get Natsume to [[SecretChaser spill the beans on the supernatural spirits thing]].
** Played straight in some of the drama [=CDs=] where she's heavily implied to have a crush on him.
* {{Meganekko}}
* ProperTightsWithASkirt: Her winter uniform.
* SecretKeeper: Promises not to tell anyone about Natsume's ability to see youkai(although he refuses to admit he can, she's just convinced of it and is extremely nosy on her own).
* SugarAndIcePersonality: Is rather strict even to her own classmates, but actually rather sensitive on the inside.

[[folder:Natori Shuuichi]]

-->'''Voiced by:''' Creator/AkiraIshida

* AnimatedTattoo: Natori has one which is also a Youkai.
* BigBrotherInstinct: Downplayed but like Nyanko-sensei, he will like pull a BigDamnHeroes moment and pop up in the nick of time. [[spoiler: Eventually deconstructed as he grows increasingly more concerned of Natsume's safety and involvement of youkai, especially knowing that Natsume's been hiding something dangerous from him. It gets to the point where he intercepts or investigates matters into Natsume's affairs behind his back. It does get reconstructed when Natsume does tell him the truth. While he still isn't always upfront, he allows Natsume to mostly handle it]].
* BigBrotherMentor: Slowly becomes this to Natsume.
* BishieSparkle: Relentlessly mocked by Natsume and Nyanko-sensei.
* {{Bishonen}}: Which helps him in his acting career.
* BigDamnHeroes: If it's not Nyanko-sensei bailing Natsume out of a tough spot, then it's probably Natori.
* BondCreatures: Even though [[BlessedWithSuck it does nothing]], his lizard Youkai seems to love Natori very much and cannot be banished, ironic considering the man is an exorcist of Youkai. It moves around his body as it pleases, but for some unknown reason, [[TheseAreThingsManWasNotMeantToKnow never goes near the left leg]].
* ChickMagnet
* ConsummateLiar: An re-occurring theme around him, though he has gotten considerably better.
* CulturedBadass: Despite being a suave part-time actor, he's quite a talented exorcist even without the backing up of a clan.
* DistinguishingMark: Has a lizard shaped birthmark that moves across his body and can only be seen by other spiritually inclined people. It's actually an ayakashi living inside his skin.
* EvenTheGuysWantHim: In the manga, Natori's horde of squeeing fangirls [[ includes Nishimura.]]
* FriendlessBackground: Like Natsume, did not have many friends growing up due to his sight.
* FantasyForbiddingFather: His father wishes to no longer be involved with youkai, and dislikes it when Natori spends time in the warehouse researching about them. To a [[{{Downplayed}} lesser]] [[ParentalSubstitute extent]], Takuma wishes Natori to not be involved with exorcism.
* GuileHero:
* HiddenDepths: According to Nyanko-sensei, he has deep-seeded hatred for ayakashi but keeps it underwraps for Natsume's sake. He is also very observant of Natsume.
* MissingMom: His mother died when Natori was young [[IllGirl due to her frail body]]. Natori, as a child, used to feel responsible for her mother's death until a younger Hiiragi cleared up that misunderstanding.
* MrFanservice
* NiceHat: More functional than fancy, but it's become a trademark part of his usual disguise.
* NoSocialSkills: During his high school years, he had a lot of trouble talking to people and would unintentionally seem cold and arrogant to his classmates. As he continued to attended exorcist meetings where he feels he could be more honest, he slowly grows out of it.
* ISeeThemToo: How he introduces himself to Natsume.
* PaperMaster: His family seems to specialize in this, as noted by Matoba.
* PaperThinDisguise: Funnily enough, all he does is put on a hat and glasses to make sure no one recognizes him as an actor (though).
* ParentalSubstitute: For Natsume, mainly when it comes to ayakashi.
* PsychicPowers: Can see and exorcise the youkai, since he's an exorcist.
* PurelyAestheticGlasses: Not quite since glass can enhance one's ability to see Ayakashi.
** [[GogglesDoSomethingUnusual Glasses Do Something Unusual]]
* SecretChaser: For a short while, he investigates [[spoiler: the Book of Friends behind Natsume's back once he heard about it's existence after chapter 62]].
* StaticCharacter: According to [[WordOfGod author's notes]] and Hiiragi in later chapters.
* ScaryShinyGlasses: In his second appearance where he has this look.
* SimpleStaff: His WeaponOfChoice. There's a paper seal through one end to make it especially effective against youkai.
* TripleShifter: Both an actor and an exorcist.
* UnknownRival: Thought of Matoba as one when they were younger.
* WellDoneSonGuy: Downplayed but his relationship with his father and grandfather. They both seem to blame their family's misfortunes on Natori. Though he doesn't look too favourable at them either, he feels being a better exorcist he might be able to take their fears away. To a less of an extent, Takuma.

[[folder:Matoba Seiji]]

-->'''Voiced by:''' Creator/JunichiSuwabe

* AdaptationalVillainy: [[NominalHero In the manga]], he follows a more business approach in that his actions his clan in mind. He is otherwise mostly apathetic towards ayakshi, and views both them and humans as potential tools his clan may benefit from or can use. [[WellIntentionedExtremist Whereas in the anime]], [[FantasticRacism he is harsher towards ayakashi]] and shows preference towards humans (or at least Natsume).
* ArcherArchetype: A bow is his WeaponOfChoice.
* BigScrewedUpFamily: The Matoba clan are ''horrible''. Their attitude towards Natsume, who was a guest among them, is to treat him with utter disdain and disrespect.
* {{Blackmail}}: [[spoiler: He likes to [[FlawExploitation exploit Natsume's weaknesses]], like his concern for a youkai's well-being or desire to keep his foster parents in the dark about his ability to see youkai because it might distress them, [[AnOfferYouCantRefuse to force Natsume to collaborate with him]] quite a few times.]] This seems to be a common practice for him as it was [[{{Lampshaded}} lampshaded]] by another exorcist in chapter 53.
* BloodKnight/ SpiritedCompetitor : Bordering between the two, seems to enjoy the challenge of a tough youkai, sounding especially disappointed when Madara wasn't going to fight back after pressing his berserk button.
* DissonantSerenity
* EnemyToAllLivingThings: His clan is notorious for their exorcise methods and contracts. Matoba himself makes it clear of his disdain for them. Youkai aren't particularly fond of him either except for some of his servants.
* EyepatchOfPower
* EyeScream: Above mentioned EyepatchOfPower also covers up a wound left from an ayakashi who attacked Matoba's right eye. He still has right eye and can see but cannot estimate distances well.
* TheGadfly: Moreso as a teenager.
* {{Jerkass}}: Just look at how he treats his shiki.
** Not much nicer to humans either. Was initially going to leave the rampaging youkai to harm the nearby town, along with the unconscious exorcist to die. Later on when he "invites" Natsume for tea, he tells how wonderful the Fujiwaras were "for taking care of a seed so rotten that harmed other children".
* ManipulativeBastard: He manipulates Natsume into helping the Matoba Clan [[spoiler:expose an exorcist possessed by a spirit that hates the Matoba Clan and attacking them by conveniently leaving out exactly who was being attacked.]] See also {{Blackmail}} above.
* NoSenseOfPersonalSpace: Though more so in the anime.
* NominalHero: In the manga, he actions are done moreso for the benefit of the clan. While he believes ayakshi are tools, he shows no strong feelings and has no problem treating humans similarly if they can be used as such. He can also be very harsh and blunt when doing so.
* PragmaticHero: Saves Natori and Natsume from the sealed youkai by killing it, not to mention being the one who helped awaken it in the first place.
* PsychicPowers: Can see and exorcise youkai, since he's an exorcist.
* SecretKeeper: Exploited once, since he knows [[spoiler: Natsume doesn't want his foster parents to know about his powers and has used this to help him out with a favour]]. See {{Blackmail}}
* SoftSpokenSadist
* TacticalWithdrawal: Does this twice: once when he found out a youkai was too powerful and incompetent to be controlled, another when he learns Natsume's companions would out-power the ones he had. He doesn't feel much of a lose the second time since he notes there [[{{Blackmail}} are other ways]] of getting Natsume's help.
* VillainTakesAnInterest: Like Natori, he wants to take Natsume under his wing and have him join his clan. Justified as the number of people with the ability to see youkai is diminishing rapidly and so clans are desperately looking for future heirs.
* WellIntentionedExtremist: Constantly insists to Natsume that what the Matoba clan does to youkai is necessary for the good of humans, even if they end up hated by humans by themselves.


-->'''Voiced by:''' Creator/MikaDoi

* AdaptationExpansion: Not majorly different but she appears slightly more in the anime than manga and was even given a back-story in season 4.
* AllOfTheOtherReindeer: In her back-story, her upbringing as an exorcist made her be considered the oddball from her other classmates.
* ChuckCunninghamSyndrome: Despite being second-in-command of Matoba clan, we don't see her after chapter 26. This is [[SubvertedTrope subverted]] in the anime as she appears twice in the 4th season (with her second appearance being [[AdaptationExpansion her back story)]].
* GrayEyes: Double subverted of type 2 and arguably type 5 but it's only apparent when you know her line of work.
* IronLady: Is the secretary and [[NumberTwo second-in-command]] for the Matoba clan.
* {{Jerkass}}: Like Matoba, she uses youkai as bait to draw in powerful shiki and sees nothing wrong with it. [[spoiler: The anime's back-story reveals that she does not mind exorcising youkai as she is taught it is the way to keep the world in balance.]]
* {{Meganekko}}: In her childhood.
* WellIntentionedExtremist: Believes that hunting youkai is part of Karma and is needed to keep the earth in balance

[[folder:Takuma Yousuke]]

-->'''Voiced by:'''

* BenevolentBoss: Unlike most of the exorcists shown so far, he seems to care about his shiki very much, even spending time with them after they complete missions. He was very hesitant on exorcising them, even though it placed his family on risk. After he loses his sight, they still remained attached to him. One desperately tries to break into his house just so she can talk with him and becomes very sadden when she understand he can longer ever see her. Another doesn't mind waiting in the house as housekeeper and waiting till he dies instead to dissolve the contract.
* BigBrotherMentor: Though initially did not want Natori to go into exorcism, he had looked after Natori when he started out.
* BroughtDownToNormal: He can no longer see ayakashi.
* FantasyForbiddingFather: Believes kids should not be involved with ayakashi if they don't have to and chides Natori from visiting exorcists meetings. He doesn't like when his daughter getting involved on his behalf as well.
* PurelyAestheticGlasses: Like Natori, he wears glasses to [[GogglesDoSomethingUnusual help seen ayakashi better]]. He was the one who taught Natori of them in the first place. .
* RetiredBadass: He used to be an exorcist but he can no longer see by the time we see him in present day. Though we never see him in action, the kimono test put him on the same level as Natori, if not slightly behind.
* WellDoneSonGuy: Downplayed since Natori interests are also of his own initiative and since Takuma is not cold but because he prioritizes Natori's safety. However, the younger Natori feels the need to prove himself as an exorcist to Tanuma and took the Tri-horn ayakashi to gain both his and other exorcist's respect as well.



!! Kogitsune (The Little Fox-child)

-->'''Voiced by:''' Creator/AkikoYajima

* AdorablyPrecociousChild
* CuteMonsterGirl: A rare male example though to be fair, [[ViewerGenderConfusion it's not hard to mistake him for a girl]].
* DudeLooksLikeALady
* HeartwarmingOrphan
* {{Kitsune}}: [[SarcasmMode You don't say!]]
** Contrary to the stereotype, however, he cannot transform (possibly because he is just too young) and is rather straightforward, not [[TheTrickster tricky]] in the least, nor particularly cunning.
* MissingMom: Died before Natsume met her.
* NoNameGiven
* MundaneObjectAmazement: Falls in love with a [[NiceHat pretty hat]] and a cracked human watch.
* PettingZooPeople: Although ordinary people just see him as a regular fox.
* PrecociousCrush: Maybe, but he probably just really, really, ''really'' admires and looks up to Natsume as a BigBrotherMentor. The rock god's "humans, ayakashi, and beasts have different times" speech to the fox child in season three about why he and Natsume shouldn't be together and his resulting angst seemed to imply [[MayDecemberRomance something else]] though.

!! Hinoe

-->'''Voiced by:''' Creator/AkemiOkamura

* AllLoveIsUnrequited: Her attraction towards Reiko....presumably.
* DoesNotLikeMen: So far, Natsume's the only exception.
* HairDecorations: A lovey hair ornament that she treasures.
* IfItsYouItsOkay: Eventually becomes attracted to Natsume over the course of the series.
* LipstickLesbian
* NoSenseOfPersonalSpace: Towards Natsume. Given the way she greeted him when she first mistook him for Reiko, she was probably like this around his grandmother as well.
* SmokingIsGlamorous
* SpiritAdvisor: On occasion, especially when Nyanko-sensei isn't available for some reason.
* StupidSexyFlanders: Constantly around Natsume
--->'''Hinoe:''' Dammit, why do you have to be a ''man''?
* UnsettlingGenderReveal: Her reaction to Natsume in their first meeting says it all.
* [[YouGottaHaveBlueHair You Gotta Have Purple Hair]]

!! Hiiragi

-->'''Voiced by:''' Creator/SatsukiYukino

* CoolMask
* BodyguardBabes: One of Natori's three female shiki.
* TheFace: Appears more frequently compared to Natori's other shiki.
* {{Familiar}}: Specifically, one of Natori's three shiki.
* {{Kuudere}}
* SubordinateExcuse: Possibly her reason for becoming one of Natori's shiki.
* TheStoic: Granted, [[CoolMask her face is completely covered]], but on top of that her voice is usually brusque and rarely emotional.

!! Misuzu

-->'''Voiced by:''' Creator/TakayaKuroda

* BadassBaritone
* CoolHorse: Its not clear if he's a horse/equine youkai.
* DarkIsNotEvil: Is quite powerful and looks is rather intimidating but he is very much on Natsume's side.
* DoesNotKnowHisOwnStrength: Tends to overdo the simplest of tasks or instructions given to him.
* EverythingsBetterWithCows: Again, its not clear from his appearance if he's a bull youkai.
* HappinessInSlavery: He ''wants'' to become Natsume's bodyguard in place of the "useless" Madara.
* KeepTheReward: Unlike the other youkai, he ''[[HonorBeforeReason doesn't want]]'' his name back.
* NobleDemon
* PerpetualSmiler: So much that his mouth doesn't even moves when he talks.
* PurpleIsPowerful: Next to Madara, he is probably one of Natsume's most powerful youkai friends
* PurpleIsTheNewBlack: His colour scheme is consistent of black and purple.
* SecretTestOfCharacter: Puts Natsume through a rather [[ComplexityAddiction dangerous test]] to see if he's worthy of him.
* StalkerWithoutACrush: He hangs around Natsume's place a lot, and pops up when you least expect him.
* YouGottaHaveBlueHair: Lavender
