!!Akihito Kanbara
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/knk_akihito_4688.jpg]]
->Voiced by: {{KENN}}

A young man who loves girls with glasses, is half-Yomu, and is thus immortal. His mother is a busy Spirit World Warrior, and is often away from home. He meets Mirai when simply walking outside of her school and seeing her standing on the edge of the roof. Unaware of her powers, he mistakenly assumes that she's about to commit suicide. Their relationship begins with Mirai constantly attacking him as practice, but blossoms into a close friendship after he accompanies her on ventures to kill violent Yomu.

[[spoiler: Akihito is actually the host for an immensely powerful Yomu known as ''Beyond the Boundary'' or ''[[TitleDrop Kyokai no Kanata]].'']]
----

* AffectionateNickname / InSeriesNickname / EmbarrassingNickname: He is called "Akkey" by Hiroomi. He says it fondly, but Akihito finds it embarrassing.
* AnguishedDeclarationOfLove: Towards Mirai.
* BigDamnHeroes: [[spoiler: Saves Mirai from being cut in half by Sakura.]]
* BirdsOfAFeather: He and Hiroomi. Hiroomi's [[TheGadfly quirks]] aside, they are very, ''very'' much alike. They generally act like they practice their interactions with each other.
** Nino-san actually calls them out on it in episode 7.
---> '''Nino-san''': You two get along far better than I expected.
* BlackEyesOfCrazy: [[spoiler: Combined with RedEyesTakeWarning when possessed by the Kyoukai no Kanata.]]
* BroughtDownToNormal: [[spoiler: When he had the Beyond the Boundary removed for 3 months, he lacked his immortality and was able to control his youmu side. Snapped back after he returns the Beyond the Boundary to being inside him]].
* ButtMonkey: Seems to be heading in that direction. Mirai uses him as a practice dummy, Mitsuki labels him a pervert and teases him, Hiroomi gives him weird nicknames...this guy doesn't get much respect.
* ChildhoodFriends: With Mitsuki and Hiroomi. [[spoiler: Although it's implied that Hiroomi and Mitsuki are less "friends" and more "guardians" to make sure The Kyoukai No Kanata doesn't go berserk.]]
* DarkAndTroubledPast: Implied. [[spoiler: The second episode shows Akihito standing over a body, staring in horror at his bloody hands. Episodes 4 and 5 reveal he actually ''did'' almost kill Hiroomi.]]
** [[spoiler: There's also the events shown partially from his childhood about being ostracized because of his immortality.]]
* DeadpanSnarker: Even when he's dripping with his own blood.
* DemonicPossession: Is briefly possessed by the Hollow Shadow.
* DoggedNiceGuy: He continually goes out of his way to help Mirai and attempts to befriend her despite her repeated refusal to get involved with him.
* FeelNoPain: A notable aversion, since despite his regeneration he frequently complains that his injuries still hurt.
* {{Fetish}}: For {{Meganekko}}.
* GoodThingYouCanHeal: Gets stabbed no less than 6 times by Mirai, at least once through the chest. While it doesn't kill the guy, Akihito acknowledges that it hurts like hell.
** [[spoiler: He also gets stabbed through the chest by the Hollow Shadow when it possesses him. Afterwards, Mirai is forced to stab him multiple times in a violent attempt to exorcise the Hollow Shadow.]]
** [[spoiler: Based on peripheral comments, he has a bit of a tendency to meddle and try to help people because his immortality means he's in little danger.]]
* HalfHumanHybrid: Half-youmu, half-human.
* HealingFactor: Akihito describes himself as immortal; he can heal from any wound. He can still feel pain, though.
* HeroicBSOD: He apparently had one right after he [[spoiler: almost killed Hiroomi.]]
* HumanMomNonhumanDad: His mom is a human Spirit Warrior and his dad is a youmu.
* IAmWho: [[spoiler: He possess the Beyond the Boundary, the strongest youmu inside him and is also immortal.]]
* ICannotSelfTerminate: [[spoiler: States in Episode 0 that death is the best option for him, and later tries to convince Hiromi to kill him when his when his ability to control his Spirit Warrior powers improves.]]
* LockedIntoStrangeness: His bangs turn green when [[spoiler: the Kyoukai no Kanata takes over.]]
* MyGodWhatHaveIDone: [[spoiler: After Mirai snaps him out of youmu mode in Episode 4. He merely {{FacePalm}}s when he sees Hiromi, Nino and Ayaka sprawled around him, but then sees Mirai's head injury, realizes he's to blame and is furious]].
* NonActionGuy: Despite hanging out with Spirit World Warriors, he doesn't have any combat skills. [[spoiler: Until he gets an EleventhHourSuperpower in Episode 12 and can partially control his youmu side at least.]]
* NotSoDifferent: From Mirai.
* PlayingWithFire: Appears to be his main method of attack when [[spoiler: possessed by the Kyoukai no Kanata.]]
* PersonOfMassDestruction: [[spoiler: When the Kyoukai No Kanata is in control, he's strong enough that it takes 3 people to contain him, and even that wasn't enough in episode 4. One stray ball of fire caused a ''humongous'' explosion several kilometers away and he created a gigantic crater around the site of his containment.]]
* TookALevelInBadass: [[spoiler:Episode 12, as he has part of the Kyoukai no Kanata in his hand he has access to some of it powers. He later reseals the Youmu inside of him again.]]
* SuperpoweredEvilSide: [[spoiler: After another youmu possesses him, the Kyoukai No Kanata takes over temporarily, turning him into a fireball-spewing rage monster. This apparently happens regularly, and his handlers may have to kill him if they can't contain his crazy-mode.]]

!!Mirai Kuriyama
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/knk_mirai_3169.jpg]]
->Voiced by: Creator/RisaTaneda


A young girl who is descended from a clan of Spirit World Warriors who are capable of manipulating their blood and turning it into weapons. Since this power was highly feared and envied, her clan was wiped out, and she was eventually the only remaining member. [[spoiler: She was temporarily taken in by the Inami Clan, but they apparently ousted her after she killed one of their members when attempting to free said member from possession by a powerful Yomu.]] At first she constantly attacks Akihito because of his immortality, thus making him a good means of training, but becomes close friends with him after he agrees to help her fight normal Yomu.

[[spoiler: After she killed Yui Inami, the Inami family was dead set on having her killed, but she was saved by the Nase clan who planned on using her to kill Akihito, who hosted an immensely powerful Yomu. Her first attempts at attacking him were not her using him for practice, but actual attempts at learning the extent of his power in order to eventually kill him. However, when she finally got the chance, she had already fallen in love with him and instead chose to sacrifice herself. While she doesn't die, she's absorbed by the Beyond the Boundary and must defeat it from within.]]
----

* ACupAngst: Not brought up much, but it's clear that Mirai is somewhat sensitive about her small bust.
* AccidentalMurder: She accidentally killed [[spoiler: her friend Yui Inami when the latter was possessed by the Hollow Shadow.]]
* ActionGirl: For an inexperienced Spirit Warrior, Mirai can kick ass like no one's business.
* AlmostKiss: In Akihito's dream. Whether she was too overwhelmed or simply couldn't stand on tiptoe for that long, either way, she disappears before anything further can happen as Akihito wakes from his coma.
* {{Adorkable}}
* BadassAdorable: Cute as a button and fully capable of beating seven [[IncrediblyLamePun shades]] of shit out of you.
* BadLiar: She'll usually start cleaning her glasses and stammering whenever she's being dishonest. Even if she's not wearing them, she'll go through the cleaning motions.
* BecauseYouWereNiceToMe: The reason for her attachment to Yui, and later to Akihito.
* BecomingTheMask: [[spoiler: She originally became friends with Akihito because the Nase clan had hired her to kill him, but she wound up falling in love with him for real and couldn't bring herself to do so.]]
* BigEater: Seems to be, judging by the large number of plates she cleaned when eating at a Mexican restaurant with Akihito. She may need to eat a lot in order to restore lost blood.
* BloodyMurder: Utilizes her blood in combat. She generally freezes it into a sword, but can also shoot droplets as projectiles and form a shield. Her blood becomes corrosive after removing her [[PowerLimiter ring]].
* {{Catchphrase}}: How unpleasant/You're unpleasant.
* CharacterTic: Turning her back on the camera and tapping on her phone, apparently blogging while asking rhetorical questions. It's usually only used as a gag though.
* CoolDownHug: [[spoiler: Glomps Akihito, stopping his fiery rampage and allowing him to regain consciousness.]]
* CrouchingMoronHiddenBadass: In the initial episodes, Mirai is presented as too clumsy and inept to really be considered a threat. However, after she gets over her angst over [[spoiler:killing Yui Inami]], she suddenly starts kicking all sorts of ass.
* CryCute: When she was lost, and again after [[spoiler: she calms down Youmu-Akihito.]]
* CuteClumsyGirl
* DarkAndTroubledPast: [[spoiler: When she was a child, Mirai was adopted by the Inami family. She was kept isolated in the attic, but was befriended by Yui, a member of the Inami family. Mirai and Yui were close friends until the day that the Hollow Shadow swept into town. Mirai and Yui were caught in its wake, leading to Yui getting possessed. Mirai accidentally killed Yui while trying to fight off the Hollow Shadow.]]
* FantasticRacism: Played for laughs. Akihito complains about being stabbed multiple times over the week by Mirai. She protests that since Akihito can't die from the wounds, he has nothing to lose. Akihito retorts that he can still feel pain and that picking on him is discrimination. [[spoiler: This turns out to be a lie and was really her trying to figure out how to kill him as part of a job.]]
* TheGlassesComeOff: [[spoiler:Before her final strike against Beyond the Boundary/Akihito in Episode 9. It's all the more meaningful considering it's an attempt to stop her love for him from blinding her (as it forces her to keep seeing his face throughout the fight) and it's the thing he loves that drew him to Mirai in the first place.]]
* InLoveWithTheMark: [[spoiler: She ends up falling for Akihito, who she was meant to kill.]]
* HeroicSelfDeprecation: Believes that she doesn't deserve to be happy or have friends. [[DoggedNiceGuy Akihito]] tries to convince her otherwise.
* [[LastOfHisKind Last Of Her Kind]]: She is the last of her clan, who were wiped out by other Spirit Warriors out of fear.
* KillTheOnesYouLove: [[spoiler: She accidentally kills Yui, who was possessed by the Hollow Shadow, and later on she is forced to kill Akihito, as it is quite possible his SuperpoweredEvilSide would become dominant if he remained in that state once the Calm leaves, and [[PersonOfMassDestruction that would be a very bad thing.]]]]
* {{Meganekko}}: One of the foremost things Akihito finds attractive about her.
* MundaneUtility: Her blood can be used as a sword, as a corrosive substance to finish off youmu...and to pick locks.
* NotSoDifferent: From Akihito. [[spoiler: At first, Mirai rejects Akihito's attempts at sympathizing with her, arguing that Akihito couldn't possibly understand. After Mirai witnesses Akihito's SuperPoweredEvilSide in action, she realizes that he really did understand what she was going through.]]
* OverdrawnAtTheBloodBank: RuleOfCool applies, but she still frequently uses several times the amount of blood a human body contains within a single fight. [[spoiler: Deconstructed after Episode 10; she used so much blood attacking the Beyond the Boundary that she doesn't exist anymore]].
* PinocchioNose: Tends to polish her glasses fervently when lying.
* PintSizedPowerhouse: She's ''tiny'' (about 4'9"), but is shown to be quite powerful.
* ProperTightsWithASkirt
* RoseHairedSweetie: Inverted. She has pink hair, but she is introverted, awkward around people and carrying some heavy-duty emotional baggage.
* ScaryShinyGlasses: Coupled with a brief {{HeroicBSOD}} when the others reveal in Episode 4 [[spoiler: how they might have to deal with youmu Akihito.]]
* UnbrokenVigil: When Akihito awakes from his coma, Sakura notes that she hasn't left his side. [[spoiler: Subverted - it's AllJustADream.]]
* UnexplainedRecovery
* [[YouGottaHaveBlueHair You Gotta Have Pink Hair]]

!!Mitsuki Nase
[[quoteright:301:http://static.tvtropes.org/pmwiki/pub/images/knk_mitsuki_5416.jpg]]
->Voiced by: Creator/MinoriChihara

Mitsuki is the youngest daughter of the Nase clan, a wealthy and powerful clan of Spirit Warriors, and shares the family power of [[BarrierWarrior creating cages]], primarily defensive shields. She also uses a rodent-like youmu familiar in combat. Mitsuki is the president of the Literature Club and friends with Akihito; evidently this means she's constantly teasing him. However, underneath her initial unapproachable exterior is a LonelyRichKid who would very much like to have friends.

----

* ActionGirl
* BarrierWarrior: She can erect a cage, like her siblings. However, hers seems to be a bit weaker.
* BrotherSisterTeam: She and Hiroomi take down a powerful youmu during the Calm.
* ChildhoodFriends: With Akihito. [[spoiler: Although it's implied that Hiroomi and Mitsuki are less "friends" and more "guardians" to make sure Akihito's youmu side doesn't go berserk.]]
* DeadpanSnarker: Particularly against Akito and Hiroomi.
* {{Familiar}}: Uses a rodent-like familiar to combat youmu.
* LonelyRichKid: Izumi tells her in a flashback that as Spirit Warriors, they're always going to be alone, moreso for Mitsuki as she's a daughter of the powerful Nase clan. She isn't shown to have plenty of friends outside the main cast.
* NotSoStoic: She often tries to hide her emotions, but is sometimes not very good at it like when Mirai convinces her to go to the festival.
* TheOjou: She comes from a well-known and very rich Spirit Warrior family, although she doesn't act in a particularly haughty or refined way.
* OralFixation: Often shown eating a Chupa-Chups.
* PetTheDog: Despite telling Akihito to avoid further contact with Mirai, Mitsuki treats Mirai nicely. Mitsuki helps the other girl find Ayaka's shop when the latter got lost and offered Mirai the gemstone after killing a youmu.
* RidiculouslyCuteCritter: Her youmu familiar.
* StayInTheKitchen: Variant, this does happen to her, but not because she is a girl, but that she is the youngest out of her family. [[spoiler: She finally defies this in Episode 12 when she enters the fight with her siblings, Sakura, and Ninomiya against Miroku.]]
* {{Tsundere}}: Hides genuine moments of kindness towards Akihito and Hiroomi under a bossy, harsh exterior.
* YaoiFangirl: Implied. She gets back at her brother for sending her resume into an idol group without her permission by putting a bunch of BL audiobooks on his phone.

!!Hiroomi Nase
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/knk_hiroomi_2_1601.jpg]]
->Voiced by: Creator/TatsuhisaSuzuki

Hiroomi is the middle child of the Nase clan and Mitsuki's older brother. Much to her dismay, this also means he claims to have a sister complex, and much of his interactions with his sister result in her reprimanding him for his behavior. (They [[AwLookTheyReallyDoLoveEachOther really do love each other]], though). He's also friends with Akihito, with whom he gets along spectacularly.

Hiroomi shares his family's cage-erecting powers. He also fights with his [[ScarfOfAsskicking scarf]], which is enchanted to erase parts of the user's body.
----

* AmbiguouslyGay: Towards Akihito of all people. He has total and complete disregard of his personal space, insists on calling him by an embarrassing nickname, and seems to be the only one who constantly worries about the others wellbeing. There is also a lingering look or two and an OutOfCharacterMoment.
** In Episode 0 there are some parellels between his first meeting/encounter of Akihito and Mirai's. [[spoiler: Including him originally there to kill him.]]
* {{Badass}}: Someone who can use a barrier to block the '''Hollow Shadow''' while simultaneously fending off dozens of youmu deserves this title.
* BarrierWarrior: Creates a huge barrier to block the Hollow Shadow while simultaneously fending off numerous smaller youmu. In fact, barriers appear to be his specialty.
** [[spoiler:Makes a barrier to contain Akihito after his SuperPoweredEvilSide takes over. He is ultimately unable to maintain the barrier under Akihito's assault.]]
* BirdsOfAFeather: He and Akihito. Hiroomi's [[TheGadfly quirks]] aside, they are very, ''very'' much alike. They generally act like they practice their interactions with each other.
** Nino-san actually calls them out on it in episode 7.
---> '''Nino-san''': You two get along far better than I expected.
* BigBrotherInstinct: For all his embarrassing siscon claims, he's quite protective of Mitsuki.
* {{Bishonen}}: So far the greatest example on the show.
* BrokenPedestal: Spent his life wanting to be like his older sister Izumi. In Episode 12, he acknowledges that he has to move past this, because [[spoiler: the same episode reveals Izumi harbors a shade in her body herself.]]
* ChildhoodFriends: With Akihito. [[spoiler: Although it's implied that Hiroomi and Mitsuki are less "friends" and more "guardians" to make sure Akihito's youmu side doesn't go berserk.]]
* CoveredWithScars: He's got some serious scars on his back. [[spoiler: Episodes 4 and 5 reveal that Akihito did this to him after having lost control of his Youmu side.]]
* TheGadfly: He enjoys teasing Akihito way too much and actively creates situations that make him uncomfortable.
* IncestSubtext: One-sided and played for laughs. He openly admits that he has a sister complex and enjoys reading literature that involve little sisters. His sister, on the other hand, does not appreciate Hiroomi's sentiments.
** He tones it down about the time the shows halfway point rolls around and it looks more like he has more of a BigBrotherInstinct than a sis-con.
* MrFanservice: Bishounen, had a shirtless scene. In the third Idol Trial short, he is naked except for his scarf. And the animators made sure [[FemaleGaze we had a good look.]] They even played up the HoYay he had with Akihito to Akihito's displeasure.
* TheNicknamer: Hiroomi gives Akihito the nickname ''Akkey'', to the latter's displeasure. According to Akihito, it makes him sound like a washed-up pop star.
* NiceJobBreakingItHero: [[spoiler:In order to see if his sisters' goals are as benign as they seem, he sneaks into the family vault and does some investigating... And ''forgets to lock the door behind him.'' This gives Miroku the opportunity he needs to steal the Hollow Shadow's Yomu Stone and feed its power to his staff.]]
* NoSenseOfPersonalSpace: Invokes this, [[TheGadfly mostly to annoy people]], partly because he's AmbiguouslyGay towards Akihito.
* ScarfOfAsskicking: He actually [[ClothingCombat uses it in battle]]. And he has more than one. We have seen four as of episode 7. He wears them because his powers as a Spirit World Warrior make him extremely sensitive even to the slightest cold.
** ImprobableWeaponUser: They work by erasing parts of the target's body. Justified, since they're probably magic.

!!Yayoi Kanbara
[[quoteright:200:http://static.tvtropes.org/pmwiki/pub/images/knk_yayoi_1434.jpg]]
->Voiced by: Hiromi Konno

Akihito's eccentric mother, who's also a busy Spirit World Warrior and thus constantly away.

* AbsurdlyYouthfulMother: She looks it, at least.
* ActionMom
* AmazinglyEmbarrassingParents: Yayoi is introduced in a holographic post-card message, in which she is wearing a skimpy cat-themed costume, using every Japanese cat-related [[VerbalTic pun]] possible. On career day, she dressed up in a panda suit and pretended to be one of the students.
** In episode 8, Akihito's mother appears again in another holographic post card. This time she's wearing a very {{Stripperiffic}} hamster outfit while talking like a ValleyGirl. Akihito actually went into a semi-HeroicBSOD out of embarrassment.
* BareYourMidriff: A staple of her provocative outfits, much to Akihito's chagrin.
* BunnyEarsLawyer: Implied. She's downright insane when it comes to parenting, but other characters speak of her skills with reverence.
* CloudCuckooLander
* IncitingIncident: [[spoiler: In a sense, she's to blame for the entire events of the series. In Episode 0 she drops a capsule containing blood in front of Mitsuki, who shares that it came with a label stating that being cursed blood, it is effective in controlling Akihito, thus leading Izumi to seek out Mirai as a means to defeat Akihito for good.]]
* InterspeciesRomance: Akihito's father is a youmu.
* ParentalAbandonment: She's always traveling, so her son has to live alone.
** GoodParents: For all her nonsense, she does care about her son.
* StrongFamilyResemblance: In the anime, she ''really'' resembles Akihito.
* [[VeryPunchableMan Very Punchable Woman]]: Her demeanor tends to annoy people so much that they want to kick her. In fact, in Episode 12, ''her own son'' slugged her a couple of times (albeit played for laughs). Later on, Sakura kicked her across the room when she reached her limit, and Ninomiya would had done the same if Sakura hadn't done so. Lastly, when Yayoi began to beat around the bush when questioned about [[spoiler: her knowledge of Beyond the Boundary, Izumi stabbed her in the chest.]]
* WackyParentSeriousChild: The Wacky Parent to Akihito's Serious Child, what with her always embarrassing him with her childish antics and revealing outfits.
* WhatTheHellHero: [[spoiler: Uh, Yayoi, is dropping a pill that contains what amounts to being kryptonite for your son in front of a member of a Spirit World Warrior- a member of the Nase, no less- really such a great idea?]]

!!Sakura Inami
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/knk_sakura_7743.jpg]]
->Voiced by: Moe Toyota
A member of the Inami family who has very little spiritual power, and must rely on a special weapon to fight Yomu rather than her own power. She can't remember who exactly gave it to her, only that [[spoiler: she could only keep it under the stipulation that she kills Mirai. Her weapon becomes more powerful as she feeds it yomu stones, but nearly devours her as well. She's saved by Mirai and reconciles with her afterwards.]]
----

* ActionGirl
* BoomStick: Her [[spoiler: supposed]] WeaponOfChoice was a halberd with a cannon attached to the blade.
* CanonForeigner: An anime-original character.
* EasilyForgiven: Mirai pretty much overlooks how she was out to murder her once she gives up on doing so. [[spoiler:They even become roommates.]]
* EmotionlessGirl: She's calm and quiet by nature.
* {{Foil}}: To Mirai, who is more emotional and has a stronger Sixth Sense. Solidified in their interactions [[spoiler: after Sakura moves in with her.]]
* IJustWantToBeBadass: Sakura has weak Spirit Warrior powers, unlike her sister Yui and Mirai. In an attempt to strengthen herself, she made a deal with [[spoiler: Miroku]]. She would borrow a weapon that would increase in strength as it is fed youmu stones [[spoiler: in exchange for killing Mirai.]]
* HeelFaceTurn
* KickChick: Is rather fond of kicks - in fact, she dropkicked Akihito in Episode 10 and sent his mother across the room two episodes later.
* LonelyRichKid: Implied to be as much, as a member of the powerful Inami clan, moreso after her sister's death.
* MixAndMatchWeapon: Her [[ImpossiblyCoolWeapon weapon]] appears to be either a sword with a long handle or a short polearm with a large blade, with [[ChainsawGood rotating teeth]] and a gun that shoots green energy beams.
* MuggleBornOfMages: Lacks the powers of her sister and other members of her clan.
* MySiblingWillLiveThroughMe: [[spoiler: Wants to be a Spirit World Warrior in place of her sister, despite the fact she lacks the Sixth Sense to do it.]]
* NewTransferStudent: She transferred into Mirai's class [[spoiler:so she could have more opportunities to kill her.]]
* NiceJobBreakingItHero: [[spoiler: Akihito was possessed by the Hollow Shadow. Mirai would have been able to fight it without him getting involved if not for her pointless pursuit of murdering Mirai. Instead, Mirai was forced to stab him and spray him in her blood. Akihito's youmu instincts kicked and [[SuperpoweredEvilSide it wasn't pretty.]]]]
* NotAMorningPerson: She has a hard time waking up, falls asleep when walking to school, and even [[AsleepInClass sleeps during class]].
* NotSoStoic: [[spoiler: When Mirai vanishes.]]
* OdangoHair
* PowerAtAPrice
** CastFromHitpoints: Her weapon becomes progressively more powerful as it's fed youmu stones, but requires more and more energy from its wielder. Eventually, the weapon will consume its wielder if the user can't supply it with enough energy.
* PerpetualFrowner: Doesn't smile very much. [[WhenSheSmiles She does, however, smile on occasion.]]
* RoaringRampageOfRevenge: Averted. [[spoiler:Initially, it appeared Sakura is trying to avenge her sister Yui by killing Mirai, but really Sakura was trying to kill Mirai as part of a deal she made with Miroku.]]
* UnwittingPawn: [[spoiler: To Miroku]]
* [[YouKilledMyFather You Killed My Sister]]: Subverted.

!!Shizuku Ninomiya
[[quoteright:253:http://static.tvtropes.org/pmwiki/pub/images/knk_nino_6330.jpg]]
->Voiced by: AkenoWatanabe
A teacher at the school the main characters attend, she is a powerful Spirit Warrior with the ability to distort space. Unlike the primarily defense-based Nase clan members, her ability has many offensive uses.
----
* ActionGirl: She's a famous Spirit Warrior.
* BadassTeacher
* BerserkButton: DO NOT mention anything about marriage while around her.
* BoisterousBruiser
* ChristmasCake: She REALLY wants to get a boyfriend.
* CombatPragmatist: She obviously didn't give a damn about taking hold of Miroku in an attempt to [[http://38.media.tumblr.com/de112655d3af4256e7a14345abfa3836/tumblr_my29rddPd91t0hdd4o2_500.gif blow off his arm with magic.]]
* CombatStilettos: Primarily fights in heels.
* DishingOutDirt: Shizuku creates a wall of earth and cracks the ground underneath [[spoiler: Akihito's]] feet when trying to defend herself and the others from his attacks.
* {{Expy}}: Shares a few traits with [[{{Naruto}} Tsunade]], a heavy drinker with earth-shattering strength who fights effortlessly without weapons by choice.
* GenkiGirl: An adult version.
* GoodOldFisticuffs: The only Spirit Warrior or ActionGirl that doesn't fight with a weapon, and is even shown taking out a hoard of youmu during The Calm with her bare hands.
* HardDrinkingPartyGirl
* HotBlooded: Threatened a student when he suggested that she was taking time off to get married. Nino-san reduced the poor boy to terrified whimpering.
* HotTeacher: She also works as a teacher.
* SuperStrength: Creates craters into the ground like it's nothing. She even wakes up a sleeping Sakura in class with a light tap of her heel, propelling the girl's desk a foot off the ground.
* StoodUp: In Episode 5, Ninomiya is shown alone reading a text message by her date who cancelled on her. It's a short moment but it's not PlayedForLaughs.
* TomboyishSidetails

!!Miroku Fujima
[[quoteright:237:http://static.tvtropes.org/pmwiki/pub/images/knk_miroku_7507.jpg]]
->Voiced by: MasayaMatsukaze
An Interrogation Officer in the Spirit World Warriors Society who comes to visit the Nase family in order to monitor the Hollow Shadow. [[spoiler:He was the one who gave Sakura her weapon, knowing that it would devour her. He apparently needed it to become stronger, and he also has plans for Akihito.]]
----
* AffablyEvil
* BodyHorror [=/=] EyeScream: Not that it bothered him, [[spoiler: the Hollow Shadow's influence begans to form through his body, even below his right eyes.]]
* CrouchingMoronHiddenBadass: Easily dispatches a youmu without moving, impressing Izumi. He plays it off as nothing important.
** He takes on Ayaka in her youmu form with minimal difficulty. Note that Ayaka is considered extremely powerful, on par with warriors of the Spirit Warrior Society. However, he fought her during the Calm, where Ayaka's powers were significantly weakened.
* {{Expy}}: Of [[spoiler: [[BlazBlue Yuuki Terumi]]. He's a SoftSpokenSadist who works for a seemingly benevolent organisation with a goal that revolves around obtaining an incredibly powerful force ForTheEvulz, who even happens to use attacks similar to Terumi's (however whereas Terumi uses snake chains, Miroku uses worm-like energy blasts). Luckily he's not a tenth as unpleasant as Terumi.]]
* ForTheEvulz: [[spoiler:Even after he loses his chance at obtaining ''Beyond the Boundary'', he still goes out of his way to amplify its power in order to lessen Mirai's chances of defeating it from within and hinder everyone else's efforts to help her, simply because it "suits someone like him."]]
* ISurrenderSuckers: [[spoiler:Upon being defeated by Izumi and knowing that his plan can no longer succeed, he proceeds to blow himself up in a ''massive'' explosion.]]
* JerkAss: He's callous, is not above murder, and [[spoiler:is willing to do things that could potentially end the world seemingly ForTheEvulz.]]
* {{Megane}}
* MrFanservice: Even Ninomiya comments on how dashing he looks.
* ObfuscatingStupidity: Subverted; he's clearly hiding something and Izumi is immediately distrustful of him.
* OralFixation: Seen sucking on a juicebox on occasion.
* SharpDressedMan: Sports a waistcoat and a bolo tie.
* StuffBlowingUp: [[spoiler: Tried to blow up Hiroomi in an abandoned bus and attempted to do the same with Izumi in a fashion of TakingYouWithMe.]]
* [[spoiler: TakingYouWithMe: After pissing off [[spoiler: [[TheStoic Izumi]] to the point of slashing him in half and realizing his plan has been foiled, he blows him up and tries to take Izumi with him. He fails.]]
* WouldHurtAChild: He doesn't hesitate to dish out on our protagonists, who are in their teens.

!!Izumi Nase
[[quoteright:300:http://static.tvtropes.org/pmwiki/pub/images/knk_izumi_2911.jpg]]
->Voiced by: AyakoKawasumi
The eldest sibling and acting head of the powerful and wealthy Nase clan of Spirit World Warriors. Her ability to generate barriers are very powerful.
----
* TheAce: She's one of the most powerful members of the cast.
** BrokenAce: Episode 12 reveals that she's TheAce because of [[spoiler: the youmu inside her]].
* [[AloofBigBrother Aloof Big Sister]]: Seems to be pretty cold to her siblings.
* AloofDarkHairedGirl: Cold, wealthy, stoic, scheming, and powerful.
* BadassLongcoat: Sports a trenchcoat over her main attire.
* BarrierWarrior: Like her siblings, Izumi's main power is creating cages.
* BeautyMark: Underneath her lip.
* BerserkButton: ''Don't'' mention [[spoiler: the youmu she harbors inside her body]].
* BladeOnAStick: Her WeaponOfChoice.
* [[spoiler: BitchInSheepsClothing: She'd been planning Akihito's murder since before the first episode. She was the one who sent Hiroomi to "subdue" him, which resulted in the scars on his back.]]
* CombatPragmatist: [[spoiler: She's been planning Akihito's murder for a very long time now because he's the host of the powerful Beyond the Boundary. This is primarily because the Society of Spirit World Warriors is also after him. She planned to have Mirai do all of the dirty work.]]
* CombatStilettos: Just like Ninomiya.
* EasilyForgiven: She gets off pretty much scott-free after [[spoiler:arranging Akihito's assassination and then convincing Mirai to sacrifice herself in order to achieve her ultimate goal of destroying the Beyond the Boundary--which, by the way, ''did not work''.]] Justified in that her actions make a lot of sense when you look at things from a pure logical standpoint, and she's clearly not ecstatic about the job either.
* FlashStep: One of many techniques she utilizes in combat.
* IDidWhatIHadToDo: [[spoiler: Her motivations for trying to kill Akihito had nothing to do with him, but everything to do with how it was the only way to defeat the Beyond the Boundary, a youmu capable of destroying the world that he was hosting. She's not exactly excited about this part of her job.]]
* LadyOfWar: She fights very elegantly, and even uses a [[NaginatasAreFeminine naginata]] for bonus points.
* [[ManipulativeBastard Manipulative Bitch]]
* NaginatasAreFeminine [=/=] BifurcatedWeapon: She uses a double-bladed naginata that can be separated into two separate swords.
* NiceJobBreakingItHero: [[spoiler: Remember how Akihito lost control of his youmu side and attacked Hiroomi? She was the one who told Hiroomi to do something that would set off his Youmu side in the first place. The incident nearly got her little brother killed and left Akihito severely traumatized.]]
* ObviouslyEvil: She's stoic, reserved, elegant, distant to her little sister, focuses a lot on reputation, and [[spoiler:stole the Hollow Shadow from Mirai. But subverted when it turns out she's actually the closest thing to a BigGood shown in the series yet.]]
* PeekABangs: Of the "concealing something" variety.
* RavenHairIvorySkin
* TheStoic
** NotSoStoic: Episode 12.
* WellIntentionedExtremist: [[spoiler:She's been plotting to have Akihito killed so Beyond the Boundary can't destroy the world.]]

->Voiced by: Creator/NaomiShindo

Ayaka makes a business out of appraising youmu and paying Spirit World warriors for the crystals youmu leave behind. She's also one herself, but prefers her kimono-sporting, humanoid form over her kitsune one.
----

* {{Badass}}: We see how powerful she is in the last episode, able to destroy at least dozens of average Youmu with one use of her BreathWeapon.
* BarrierWarrior: Is also capable of setting up barriers like the Nase clan. When she and Hiroomi team up in Episode 4, it's her job to repair the cage Hiroomi keeps up.
* BreathWeapon: In her Kitsune form.
* CovertPervert: Apparently also sells provocative pictures as a side-business. [[spoiler:She has nudes of ''her sister'', it seems.]]
* CuteMonsterGirl: Also a youmu, but quite pretty.
* IAmNotLeftHanded: Even when The Calm took place, she was still powerful enough to hold her own against Miroku.
* KansaiRegionalAccent
* KimonoIsTraditional: Wears an elegant kimono.
* {{Kitsune}}: Though she prefers being in her human form.
* VoluntaryShapeshifting: Has a {{kitsune}} animal form. Even during The Calm, she shows herself to be fairly powerful.

->Voiced by: Yuri Yamaoka

An anime-only character, Ai is Ayaka's cute younger sister.
----

* BitchInSheepsClothing: Only in the Idol Trial shorts.
* CanonForeigner: An anime-original character.
* CuteMonsterGirl: She's a youmu, although you couldn't tell by looking at her.
* DeliberatelyCuteChild: In the Idol Trial shorts.
* HiddenBuxom
* OurWerebeastsAreDifferent: Is apparently a (friendly) [[http://en.wikipedia.org/wiki/Nekomata nekomata]], but usually takes the form of a human.
* {{Youkai}}: To be specific, a nekomata.

!!Hollow Shadow

A very powerful youmu whose power distorts the space around it, resulting in the world gaining a purple tint and its outward appearance as a huge shadow, earning it its name. This youmu was what caused [[spoiler:Mirai to kill Yui when it possessed her.]]

* AttackItsWeakpoint: What you have to do to actually bring the fight into more even ground in the first place, then again to finally kill it.
* BigBad: [[spoiler: For the first half of the series.]]
* CombatTentacles: The core's main form of attack.
* DemonicPossession: Twice. First to [[spoiler:Inami Yui]], and then to [[spoiler:Akihito.]] In the later case, it was chased out before it could fully take over.
* DiscOneFinalBoss
* MoneySpider: As put by Shizuku, killing it would allow one to live almost like a king for a year.
* PsychologicalTormentZone: It's insides consist of massive labyrinths crafted from the memories of the intruders, and it also preys upon the regrets and fears of its victims.
* ScrewThisImOuttaHere: What it attempts to do once [[spoiler:Akihito's body is damaged enough, as per his BatmanGambit.]]
* TheWorfEffect: For such a massive and powerful youmu, it went down rather quickly. [[spoiler:The methods required to defeat it directly cause the emergence of Beyond the Boundary in Akihito again.]]
* YouCannotGraspTheTrueForm: The huge shadow is actually the result of space being distorted around the actual youmu because of how powerful it is. [[spoiler:Once the youmu is sufficiently weakened by Mirai, the shadow disappears and it's true form is revealed.]]

!!Beyond the Boundary/Kyoukai no Kanata
[[caption-width-right:302:[[labelnote:Beyond the Boundary/Kyoukai no Kanata]]http://static.tvtropes.org/pmwiki/pub/images/knk_6530.jpg[[/labelnote]]]]

A youmu of inconceivable powers. Born of the negative feelings of countless humans, this massive entity has the power to destroy the world with ease. [[spoiler: Since before the show, it had been sealed inside of Akihito for an unknown amount of time, emerging whenever his human consciousness grew weak due to extreme amounts of physical damage. This youmu's mere presence was also responsible for Akihito being NighInvulnerable.]]

[[spoiler:Due to how dangerous it is, Izumi had conspired to have Mirai kill Akihito, and through him, the youmu, before people like Miroku could somehow use it for their own ends. It is extracted from Akihito by Mirai at the end of episode 9, and remains as such for three months, before Akihito absorbs it back into his body again near the end of the final episode.]]

* AntiMagic: On numerous ocassions it has shown the ability to negate the powers of spirit warriors, including Mirai's blood, even during the Calm.
* BiggerBad
* DemonicPossession: [[spoiler:This was Akihito's so-called "youmu side". Therefore, every time it appeared it took over was an instance of this trope.]]
* EldritchAbomination: To a higher degree than even youmu like the Hollow Shadow. It's power is such that [[spoiler:even greatly weakened by the Calm, Akihito is STILL a PersonOfMassDestruction when possessed by it.]]
* GenreSavvy: It knows it becomes weaker during the Calm, so rather than stay and raze everything to the ground, it actually retreats when confronted in order to wait out the Calm.
* HellIsThatNoise: A loud, booming sound that only Akihito can hear,[[spoiler: presumably due to having harbored it.]]
* NighInvulnerable: The only thing that could supposedly kill it was the blood of the Kuriyama clan. [[spoiler: And while it was said blood that was capable of extracting it from Akihito, what stopped it in the end was being absorbed back into Akihito.]]
** SuperEmpowering: [[spoiler:Akihito having this thing inside of him is what HIM NighInvulnerable in the first place.]]
* NoHoldsBarredBeatdown: [[spoiler:On the receiving end of one from Akihito in episode 12.]]
* PlayingWithFire: [[spoiler:Inside or outside Akihito, this seems to be its most common form of attack.]]
* PsychologicalTormentZone
* RealityWarper: Hoo boy. Whenever it manifests, strange phenonema abound. The ground becomes reflective, like looking upon a lake, and gains a strange tint. Youmu grow very active. [[spoiler:When it was freed from Akihito, it ''created a new dimension'' and stayed there to save itself from death, then began to absorb the powers of spirit hunters and youmu alike in order to sustain itself. Its insides feature an almost exact copy of whatever it is reflecting, and it can be basically anywhere in it at once to attack.]]
* SealedEvilInACan
** SealedInsideAPersonShapedCan: [[spoiler:Akihito is the can.]]
* TheEndOfTheWorldAsWeKnowIt: What it can bring about if left alone.
* TitleDrop [=/=] CharacterTitle: The titular "Kyoukai no Kanata."
* YouCannotGraspTheTrueForm: [[spoiler:The closest thing it had to this (and what it defaults to, really) was Akihito's appearance. Without that, it's basically a gigantic reflective surface.]]
* WalkingSpoiler: The significance of this being to the story is ridiculous.
