Sakai Yuji thought he was an OrdinaryHighSchoolStudent... until time stopped one day and everyone around him was turned into light and consumed by a huge monster, right before his eyes. He was saved by a girl with long red hair who drove the monster off with [[FlamingSword sword and flame]]. "[[TomatoInTheMirror You don't exist anymore]]", she told him.

The Denizens of the Crimson World are monsters from another world who consume the "power of existence" of humans. The power of a human that is leftover becomes a Torch, a shell of their former self, destined to disappear without a trace -- physical or mental -- when their remaining power burns away. Flame Haze are independent humans who have allied themselves with the kings of the other world, gaining the power to fight back.

But Yuji is no ordinary Torch, and the minion fought that day is only the beginning of the troubles his city is about to face...

''Shakugan no Shana'' is a series of light novels by Takahashi Yashichirou. The anime adaptation was produced by JCStaff and ran for three seasons: the first aired in 2005, and the second in 2007. A movie readaption of the first novel was released in Japan on April 21st, 2007. Starting in October 2009, {{OVA}}s were released every four months or so under the name ''Shakugan no Shana S''. The third and final season of the anime [[ScheduleSlip premiered in Fall of 2011]].

A series of omake called ''Shana-tan'' and ''Hecate-tan'' have also been released which parody the events of the series with SuperDeformed characters. There are omake episodes for every season, plus the movie and ''Shakugan no Shana S'', the first episode of the latter called (appropriately enough) ''Shakugan no Shana-tan G''.

[[Characters/ShakuganNoShana The character sheet can be found here.]]

----
!!'''This series provides examples of:'''

* AllJustADream: The second season starts with Yuji trapped inside a dream (created by the ''real'' first villain of the season). Yuji picks up on some deja vu, but when complete scenes and defeated villains from the first season start showing up, ''then'' he knows something's wrong. No one will listen to him or tell him anything he--the one the dream is based on--doesn't already know. The dream falls apart once he pieces everything together.
* AlmostKiss: Happens a couple of times in the anime and light novels; most of the time Shana is the one who begins it, but it is always interrupted. The first time it happens in anime Shana backs out of the kiss (which she hinted would be a reward for Yuji's good performance in the battle) and shoved melon bread into his face instead. It's no wonder that in their [[spoiler: SacredFirstKiss it's Yuji who initiates it.]]
* AlternateContinuity: The movie provides a closer adaptation of the events of the first novel than the anime, thus differing in a few respects, such as using an important plot point that the anime reserves until the end of the first season.
* AnyoneCanDie: Season 3 in particular.
* ArtEvolution: Other than the flame effects improving throughout the series, ''Final'' also greatly varies the amount of runic circles used in Unrestricted Spells, up from the one circle and ribbons used in the first two.
** Very notable in Yuji, whose improved looks also serve to emphasize his [[spoiler: FaceHeelTurn.]] He gets better looking than any other character since the first season.
** The original light novel illustrations and the manga adaptations also experience this.
* ArtificialRiverbank: Where the [[spoiler:OminousFloatingCastle first appears.]] Also where [[spoiler:Shana gets ImpaledWithExtremePrejudice.]]
* BabiesMakeEverythingBetter: [[spoiler: Yuji's upcoming sibling lifts the family's spirits.]]
** [[spoiler:''Literally'', as the reveal of Pheles and Johann's baby Justus virtually ends all the fighting, sans the final battle.]]
* BattleCouple: Shana (ActionGirlfriend) and Yuji (MissionControl). In ''Shakugan no Shana Second'', Yuji, due to training under Shana, Wilhelmina, and Margery, begins to take a more martial role in conflicts, while still serving as MissionControl.
** In ''Shakugan no Shana SIII'', which contains short stories that place after the events of the final volume of the light novel series (and thus the end of ''Shakugan no Shana Final''), Yuji has become powerful and skilled enough to join Shana to become a full-fledged BattleCouple, [[spoiler: hunting down Crimson Denizens and Lords that refuse to live peacefully in Xanadu.]]
* BeachEpisode: Well, water park, anyway. Also qualifies as a BreatherEpisode considering the intensity of action in the previous episodes.
* BettyAndVeronica: Yoshida is the Betty while Shana is the Veronica.
* {{BFS}}: Sorath's (and later Yuji's) Blutsauger.
* BigBadassBattleSequence: [[spoiler:The war between Flame Haze and Crimson Denizens in season 3.]]
* BigGood: [[spoiler:The final light novel's resolution and ending reveals that Snake of the Festival Yuji is closer to this than the BigBad.]]
* BittersweetEnding: The ending a whole is too happy to be this entry, considering that [[spoiler: Shana and Yuji [[TheyDo end up romantically involved]], the ForeverWar is ended and countless future generations of humans and Denizens are spared, Flame Hazes can pursue lives beyond that of revenge-driven soldiers, and all of Misaki City's devoured humans are resurrected.]] There are still elements of this type of ending, though. [[spoiler: Thousands of Flame Hazes are killed in the conflict, most notably Khamsin. By merging with the Snake of the Festival, Yuji's "previous" existence was displaced, so those LockedOutOfTheLoop no longer know he exists, including his friend Matake Ogata, best friend Ike, and his own parents, who are raising his sister as their only child. In addition, Kazumi, Eita, Keisaku, Margery, and Marchosias will never see Shana or Yuji again, as the entrance to Xanadu has disappeared. The Crimson Lords contracted to Flame Hazes still on Earth are incapable of returning to the Crimson Realm, as Xanadu now occupies the space through which they traveled from the Crimson Realm to Earth. Finally, there is no Misaki City for Shana and Yuji in Xanadu, which is otherwise a perfect replica of Earth.]]
* BladeBrake: Provided the page picture.
* BlandNameProduct: Buying [=CDs=] at HNV.
* BossSubtitles: Every character with powers has a title, and everyone constantly addresses everyone else by full title and name.
** AwesomeMcCoolname
* CessationOfExistence: What happens to people who become torches; after gradually becoming less and less present in the world, along with RetGone at the moment of cessation.
* ChekhovsGun: The anti-flame ring, Azure. After being forgotten for most of the first season it ends up [[spoiler: saving Yuji when Shana summons Alastor]]. [[spoiler:Snake of the Festival Yuji also uses it liberally throughout ''Final'' to NoSell most attacks from Shana and the other Flame Haze, due to most relying on fire and their elemental power]].
** Azure pulls double duty as ChekhovsGun. [[spoiler: It is also responsible for the full restoration of Yuji's existence at the end of series. Friagne, the villain of the first novel/anime arc was using Azure for more than just protection from Flame Hazes; it was also key to the ritual he created to give his Rinne Marianne a full existence. The ring had an Unrestricted Spell inserted into it, Resurrection, which is actually Lamies' spell, the one that is used to restore his painting and the humans of Misaki City at the end of series. It would be this spell, fueled by the massive amounts of Power of Existence created through the City Devourer spell, that would give Marianne a true existence. Ultimately, the spell goes unactivated because Friagne and his plan are destroyed, and it lies dormant in the ring until the end. In the final light novel (and the last episode of ''Shakugan no Shana Final''), Lamies' gift to Yuji is to change the activation trigger for Resurrection, the trigger of course being a kiss. In short, this development was foreshadowed as early as the first book of the series, which explicitly established the spell, the ring's role, and Lamies' creation of it. Everything needed to set the stage of Yuji's restoration was placed well in advance. The anime's non-textual nature means that the exposition revealing this is left out, though it is alluded to. As a result, Yuji's restoration appears to come somewhat out of left field.]]
* CityOfAdventure: The first villain started it, hanging around Misaki City as part of some [[EvilPlan sinister scheme]] and gaining Shana's notice. Shana and Yuji being who and what they are tends to attract the rest of the attention. [[LampshadeHanging Lampshaded]] in the second season by speculation that Misaki City has become some sort of naturally-occurring nexus of misfortune. [[spoiler: The city later earns the nickname/title, "Maelstrom of Warfare"]]
* CivilWar: The Civil War, between the Four Gods of Earth (and their followers the West Army) and the rest of the Flame Haze (East Army), broke out in 1863 during the [[UsefulNotes/TheAmericanCivilWar American Civil War]]. The Four Gods of Earth were Native American Flame Haze who resolved, like all Flame Haze, to remain uninvolved in human affairs, despite the treatment of their people at the hands of the European settlers and their descendants. When a group of American soldiers killed a young Native American girl praying for deliverance, the Four Gods finally snapped, killed the soldiers, and resolved to destroy the United States. The rest of the Flame Haze, opposing this violation of their neutrality, fought against them. Ultimately, the East Army won the war because the Four Gods realized that their vendetta was distracting the Flame Haze from hunting Crimson Denizens and Lords, who were running rampant at this time. This caused them to cease fighting. As a peace offering, the Four Gods were made leaders of the branches of Outlaw (the Flame Haze support organization) in North and South America.
* ClingyMacGuffin: The Midnight Lost Child (''Reiji Maigo''). Yuji needs it to live, and removing such Treasures in general is supposed to be dangerous.
* ClothingDamage: To varying degrees, and Shana is notorious for it.
* CriticalExistenceFailure: Not existing any more is not as debilitating as it sounds.
* CurbStompBattle: [[spoiler:Snake of the Festival Yuji]] delivers one to [[spoiler:Shana]] and the [[spoiler:Hazes]], the beatdown was so severe that [[spoiler:Shana]] couldn't believe that [[spoiler:Yuji]] hadn't had his mind taken over by [[spoiler:Snake of The Festival]]. [[spoiler:Yuji]] insists that there is only him in control and later tries to apologize for using force against her.
** [[spoiler: The Flame Haze army is decisively routed at the battle of the ''Sereiden''. So many are killed or demoralized that, with the exception of a few renegade Flame Haze led by Shana, they are knocked out of the war.]]
* DangerouslyShortSkirt: Shana.
* DeadToBeginWith: As impatiently explained by Shana, the original Yuji's life was consumed before the anime started, and he is just a Torch--the remainder of that lifeforce, a placeholder to preserve the balance while quietly fading away.
** Though how long he'd been dead [[spoiler: considering that he's been the Midnight Lost Child's container]] is never elaborated upon.
* DefusingTheTykeBomb: Yuji's influence makes Shana think of herself as more than the Flame Haze she was raised to be.
* DemonicInvaders
* [[DidYouJustPunchOutCthulhu Did You Just Cut Cthulhu?]]: In episode 13 of season 3, [[spoiler:Shana manages to cut Snake of the Festival Yuji. This is the first time anybody has managed to get in a decent hit on him, much less hurt him.]]
** And in subsequent episodes, Shana manages to fight him on more equal footing.
* DoesThisRemindYouOfAnything: Hecate [[spoiler:and her interaction with Yuji]] at the end of the first season.
** Which leaded into the [[FanNickname Youtube-Nickname]] "''Orgasm Girl''".
** The omake picks up on this interaction with a slew of [[spoiler:impromptu H-scenes]].
** One scene begins with Margery Daw making sounds of pleasure while the camera pans up from her curled toes... [[spoiler:she's actually getting a massage.]]
* EnemyMine: Shana and Kazumi form a quirky alliance in response to Konoe's perceived usurping of Yuji's affections, although they spend more time [[{{Wangst}} moping about it]] than doing anything constructive. Eventually their understanding of each other extends beyond the non-combative theatre of operations.
* TheExtremistWasRight: [[spoiler:Snake of the Festival Yuji succeeds in his/their plan to create a duplicate world for Crimson Denizens to live without needing to feed on humans' Power of Existence. The Crimson Denizens go a step further and, admiring humanity and wishing to coexist with it, allow the Flame Haze to create a limiter preventing them from devouring humans. An uncountable number of people are saved from future harm. Since Crimson Denizens no longer feed on humans and threaten the balance of the world, the need for the Flame Haze to fight them are gone, allowing them to finally be people instead of walking weapons. Yuji is able to have a relationship with Shana that is not marred by endless conflict that would have probably resulted in her death one day, and the ForeverWar is ended.]]
* EyesAlwaysShut: Yuji's Mom, she does open them once in a while.
** Tanaka opens his eyes only under extreme stress.
* FaceHeelTurn: [[spoiler: Yuji]]. To be fair, [[TragicVillain there wasn't any other choice]], to fulfill his dream [[spoiler: to live on with Shana forever in peace]]
* FanService: Sorath neatly slices Shana's clothing while she is restrained.
** Giving the class girls a shower scene during Season 2's school festival also counts. Groping is involved.
* FirstEpisodeSpoiler: The first episode reveals that Yuji is a Torch. Yuji being TheProtagonist, this is a big deal to the rest of the series. You can't describe this series to anyone without spoiling the plot twist of that first episode.
** For some reason, they decided to put [[spoiler:Yuji's [[SubvertedTrope apparent]] FaceHeelTurn]] before [[spoiler:Yuji's permanent death and reincarnation]] in the first few minutes of the final season.
* FlamingSword: The titular artifact, Shana's name comes from the sword.
** While its true that Shana got her name from her sword, the title of the series, which translates to "Burning-Eyed Shana", refers to Shana the girl, not Shana the sword.
** Mathilde (Shana's predecessor) can make swords, axes and shields with her flames. She can even summon an army of knights complete with armour, horses, and rams made out of fire.
* FloatingContinent: Bal Masque's headquarters, Seireiden, as well as the Tendokyuu, where Shana received her training.
* ForbiddenChekhovsGun: A Flame Haze awakening/summoning their sponsoring Lord's full power into this world, killing them from inability to contain their Lord's massive power. As revealed by the movie, the first villain was using a gun that ''induced'' this to kill off the Flame Haze who came after him--thus forcing their Lords to depart or else risk destroying the balance. Used as a suicide attack in the anime's {{backstory}} by Alastor's previous vessel.
** [[spoiler: [[AvertedTrope Shana is a rare Flame Haze capable of handling Alastor's massive existence.]]]]
** The cross pendant [[spoiler:that Pheles gives Kazumi is designed to summon her at the cost of the summoner's life.]][[spoiler:[[AvertedTrope Except not really.]]]]
* {{Foreshadowing}}: Didn't watch the ''S'' episodes and wondering what's up with Season 3? ''S'' are relevant, but the significant lines are few and rare. In order:
** Episode 1 involves the relationship with Shana and Yuji, and how much they have progressed and understand each other. Notice anything strange about the length of time they've been together?
** Episode 2 looks at Wilhelmina's side, and she wonders about Yuji's personality.
** Episodes 3 and 4 acts as foils to the main series, as they focus on the past of Shana on another Tomogara from a different time. That ending... is rather open.
* FreakyFridayFlip: In the first ''Shakugan no Shana S'' OVA, Yuji accidentally uses the artifact Reshuffle to bodyswap with Shana. Naturally, Yuji-as-Shana is [[{{moe}} endearingly]] [[{{tsundere}} deredere]], while Shana's usual {{tsundere}} antics [[DoubleStandard come across as mildly repulsive]]. They spend the entire episode trying to keep the swap a secret under Alastor's orders, [[spoiler:because Reshuffle only works if there are no barriers between the users' hearts and he doesn't want their relationship to go public]].
* FreakOut: [[InvokedTrope Invoked]] by Yuji [[spoiler:when he is apprehended by Zarovee]]. This may fall into {{Narm}}, depending on your viewpoint.
** One character plays this horrifically straight: [[spoiler:Tanaka, when he sees Ogata lose an arm and a leg after being blasted by Margery Daw in her blind rage.]]
** Keisaku in episode 2 of the final season when his Denizen detector starts reacting (to [[spoiler:The Snake of the Festival inside Yuji]]) and he can't run away as Margery advised him to because he's stuck on a train. It turns out the Denizen was on a passing train.
* FreezeFrameBonus: In the third episode of season 1 when Shana trashes various teachers, one of them looks like AdolfHitler.
* FriendToAllLivingThings: Konoe
* FromBadToWorse: [[spoiler:Snake of the Festival.]] Long story short, [[spoiler:Yuji betrays the Flame Haze soon after confessing to Shana and became the final, ultimate antagonist, albeit [[TragicVillain tragically]].]]
* FuroScene: Episode 7
* GambitPileup: The final season's last episodes are this. The Snake of the Festival and [[spoiler: Yuji]] are working together to create Xanadu, a paradise for Denizens with limitless Power of Existence. The Snake of the Festival's desire is to grant the Denizens' wishes, while [[spoiler: Yuji]] wants to prevent humans from ever being eaten by Denizens, so a world separate from Earth where Denizens do not ''need'' to eat humans to survive is what he wants as well. They select Misaki City for Xanadu's creation, because the huge amounts of distortions there can be used to create a gap through which Power of Existence can be poured into the Abyss to create Xanadu. But [[spoiler: Yuji]] manipulates the Snake of the Festival into choosing this location, something the Snake recognizes and respects, because Yoshida Kazumi is there, and because the departing Crimson Denizens will leave behind their Power of Existence. [[spoiler: Yuji]] can use Kazumi's memories of Misaki City and the remaining power to restore all humans devoured by Denizens in Misaki City. Meanwhile, Lamies is working with Bal Masqué also to gain access to the Power of Existence left behind, with which he can use as fuel for his Unrestricted Method (a method with which nonexistent things can be restored) to restore a painting precious to him. [[spoiler: Yuji]] also wants to use this spell, because it is key to his restoring the Misaki City humans. A fourth party becomes involved as well: Pheles and Johann, and they ''also'' want to use the left behind Power of Existence as well. A large amount of Power of Existence is crucial [[spoiler: to merge their existence into a new being]]. Shana and her band of Flame Hazes have their own gambit, to alter Xanadu's creation to ensure it is ''impossible'' for Denizens to eat humans, thus preventing the same distortion crisis from returning. As a backup gambit, the Flame Haze Ernest Flieder attempts to convince the Crimson Denizen Rofocale, a servant of the God of Guidance Shaher, to command Denizens to not eat humans in Xanadu. While all this is going on, the Flame Hazes Sophie Sawallisch and Rebecca Reed are working to gather thousands of Flame Hazes to travel to Xanadu with the Denizens to keep an eye on them. Incredibly, all of these gambits are achieved (except for Flieder's), though in Shana and company's case, not in the way they imagined it would.
* GeodesicCast: Every Flame Haze has a weapon, a Crimson Lord, and a magical object through which the Lord speaks. And in Season Three, there are a ''whole damn lot'' of Flame Haze.
* GiantFood: Season 2 filler episode. All of the student characters met and ate at a restaurant that super sized everything. The bowls looked like they were meant for real giants and not puny humans.
* GoMadFromTheRevelation: [[spoiler: When Snake!Yuji reveals that the success of his plan will prevent Denizens from ever having to feed on humans again, the majority of the Flame Haze army goes insane from the realization that their eternal lives will become meaningless, thus becoming easy prey for the Denizen army]].
* GreyAndGrayMorality: [[spoiler: The final arc which featured the final war between the Flame Haze as led by Shana on one side and Bal Masqué as led by Snake of the Festival Yuji on the other. Both of them are [[ADarkerShadeOfGrey darker shades of grey]], with the latter's leader verging onto ALighterShadeOfBlack. Bal Masqué wants to create a paradise called Xanadu with limitless Power of Existence, allowing Crimson Denizens to coexist peacefully with humans in that world. With the unlimited Power of Existence and the humans not being devoured, the distortions that threaten Earth and the Crimson World's existence will cease. The Flame Haze, however, believe that the Crimson Denizens lack the self-restraint to not eat humans even with limitless Power of Existence, making them have a HobbesWasRight view, and feel that Xanadu will only exacerbate the distortions. Both sides oftentimes show little regard for humanity, with Flame Haze just as willing to use humans' Power of Existence as Crimson Denizens if it suits their purposes. In short, Shana and company view Yuji and the Snake of the Festival as too naïve, while Yuji and the Snake view the Flame Haze as too cynical. Ultimately, the Crimson Denizens win the war, but having come to admire humanity, allow the Flame Haze to input a code into Xanadu's blueprints preventing them from eating humans.]]
* HappilyMarried: The Sakai parents.
* HeroAntagonist: [[spoiler:Yuji Sakai.]]
* HeroicBSOD: Wilhelmina has this in the last episode of season one when [[spoiler:she thinks Shana died summoning Alastor.]] She literally can't stand up without Margery's support.
* HeroicSacrifice:
** Yuji offers up part of his own Power of Existence early in the series so Shana can repair the classroom and students damaged by Friagne, rather than let Shana use a human's Power of Existence, which would have erased them from existence. At the time, neither Yuji or Shana knew that he had the Midnight Lost Child, which replenishes his Power of Existence, and assumed that this would hasten his death. This is a critical first step in challenging Shana's [[LawfulNeutral protect-the-balance-over-humanity worldview]], as well as an important step in Shana's evolving crush on Yuji.
** [[spoiler:Later in the series, Kazumi utilizes a Treasure Tool that, while calling [[ActionGirl Pheles]] for aid, will use up all of her Power of Existence. She still does it. [[AvertedTrope She lives.]] [[SecretTestOfCharacter Turns out Pheles lied.]]]]
** [[spoiler:Also, the [[AuthorityEqualsAsskicking Bal Masqué general]] Decarabia. While Decarabia doesn't deliberately die, he is willing to risk, and ultimately lose, his life to hold off the Flame Haze long enough for a Bal Masqué army to come to defend Seireiden, Bal Masqué's headquarters.]]
* HoldingBackThePhlebotinum - In the form of [[spoiler:Alastor, because he's used as a MacGuffin or weapon as opposed to a person in this instance.]]
* IgnoredConfession: Overlaps with LoveConfession.
* IHaveTheHighGround: Most non-humans with the necessary jumping ability exhibit this.
* IJustWantToBeNormal: Tanaka goes through a period of this after he starts going out with Ogata because he doesn't want to see her maimed again. In the end, [[spoiler:he goes through with it.]]
* ImpaledWithExtremePrejudice: [[spoiler:Shana, TakingTheBullet for Yuji.]]
* InfantImmortality: Subverted in the very first episode, but never done to the same extent again.
* InstantRunes: Often in the form of growing, encircling ribbons of blue runes.
** By Final, rune circles have become most common display, and with much more variety than the standard circle from season one.
* ItBeganWithATwistOfFate: Lampshaded in the opening narration. Yuiji wonders how different his life would have been had he not decided to go to the CD store on the fateful afternoon where he met [[TheHero Shana]] and found out that he's a Torch with incredible magical power.
* [[JustAMachine Just A Torch]] : Quite a few Flame Haze and Denizens share this view, in particular, Shana to Yuji at the start, and [[spoiler:Yuji]] to [[spoiler: himself briefly]].
* [[KatanasAreJustBetter Nodachis Are Just Better]]: Shana wields a nodachi (Japanese longsword).
* {{Kiai}}: Margery Daw's howl in her werewolf form (it looks more like a bear though)
** Shana's battle cry right before she 'finished off' Sabrac sounded a lot like a high-pitched version of the "Punch" of "Falcon Punch"
* KissingDiscretionShot: [[spoiler:When Shana and Yuji kiss at the end of the third season.]]
* LastNameBasis: Strangely, Ike and Sakai. They're supposedly best friends, but only ever refer to each other by last name.
* LethalChef: Wilhelmina. CABBAGE ROLL OF DOOM.
** Shana as well, but she learns better.
* LieToTheBeholder: A passive version: normal people perceive Shana as Yukari Hirai, due to her taking in the girl's last remnants of Existence.
* LifeEnergy: Called Power of Existence
* LongRunners: Barely.
* LoveTriangle: Shana-Yuji-Kazumi.
* MatchmakerCrush: Ike tries to help Kazumi to have time and hook up with Yuji. When he chastises Yuji for leading her on, Yuji confronts Ike about his own feelings for her. It isn't until the second season that Ike tries to do anything for himself, though. [[spoiler:But even so, Kazumi still holds her heart for Yuji.]]
* MeetCute: Just replace "crashing into each other" with "getting run through with a sword" and you've got the same formula.
* {{Meido}}: Wilhelmina [[VerbalTic ~de arimasu]].
* MissionControl: Tanaka, Satou, and sometimes Yuji. The former two use the Haridan when the frontline requires a sitrep.
* MuggleAndMagicalLoveTriangle: Yuji is in this scenario with Shana (magical) and Kazumi (normal).
* NakedFirstImpression: In Margery's flashback, when she and Yuri first meet she is naked because she was using the Purification Flame to clean her body.
* NiceHat: Hecate seems to wear a pillow adorned with two large, red jewels.
* {{Omake}}: [=DVD=] specials: two mini-episodes of "Shakugan no Shana-tan" and one of "Itadaki no Hecate-tan", featuring a pocket-sized version of the titular character that spoofed events in the main series.
* OpeningNarration: By Alastor in the first season: "Infinite time stopped beating its heart, and humans burnt away without making any noise. Not one person notices as the world becomes dislocated and is covered in the flames of The Crimson World."
** In the dub; "A heartbeat that lasts for eternity, lives consumed in soundless balls of fire. No one is aware as the world is displaced, and the flames of the Crimson World sweep over all."
* OptOut: Eita Tanaka in season 2.
** [[spoiler: [[ResignationsNotAccepted He's back]] in Season 3.]]
* OrderVsChaos: The Denizens, led by a WellIntentionedExtremist who wants to create a duplicate world where vicious, human-eating Denizens can live without consuming humans, or mostly KnightTemplar and [[HeWhoFightsMonsters sometimes corrupt and immoral]] Flame Haze, who fear that the Crimson Denizens will continue to devour humans in the duplicate world anyway and who will use humans' Power of Existence in order to protect the balance. [[SadisticChoice Pick your side.]]
* OrdinaryHighSchoolStudent: Yuji, or so he thought.
* PantyShot: 3 in quick succession during the final battle in the first season. And a quick shot during the first OP. Also a couple slips during season 2's battle penultimate battle. You know the show is almost over when they start upskirting Shana.
** They also do it [[{{Fanservice}} somewhat less discreetly]] and more often during the Shana S ova. [[spoiler:Blue with white stripes]]
** Again in the first episode of the third season. We see her strip down to her panties, [[GoofyPrintUnderwear which have a rather childish anime character on their seat]].
* PhantomZone: ''Fuzetsu'' barriers. Everything inside the barrier is frozen in place, while everyone outside the barrier temporarily forgets about and subconsciously avoids the enclosed area. This only applies to normal people, of course. Also, any environmental damage done inside a ''fuzetsu'' can be undone, given sufficient energy.
* PhraseCatcher: Marcosius seems to refer to Margery as "My (adjective/verbing) (noun), Margery Daw" quite a lot.
* PigeonholedVoiceActor: RieKugimiya (Shana's VA) has become known for her wrathful loli {{tsundere}} roles, which also include Louise (''LightNovel/ZeroNoTsukaima''), Nagi (''Manga/HayateTheCombatButler'') and Taiga (''LightNovel/{{Toradora}}'').
* PlayingWithFire: This is how most Flame Haze and Denizens manifest their powers, but exceptions pop up from time to time.
* POVBoyPosterGirl: There are some scenes from Shana's POV, but it's still mostly from Yuji.
* PowerGivesYouWings: Shana grows a pair in her rematch with Margery.
* ThePowerOfLove: A ''major'' theme of the series, triumphing over its opposite LoveIsAWeakness. Originally, Shana's feelings for Yuji causes confusion with Friagne and Margery exploit in her battles against her, and later leaves her conflicted over her role as a Flame Haze. However, these same feelings mean that when Yuji is supporting her, her confidence increases enormously, resulting in the above-mentioned wings. Later, it grants her incredible strength of will and fuels one her primary goals: [[spoiler: [[ICanChangeMyBeloved redeeming Yuji.]]]] This same power also drives Yuji to become stronger to fight by Shana's side, and is responsible for Yuji later [[spoiler: having the audacity and determination to join the Snake of the Festival in changing the world, all for the sake of protecting his loved ones and free Shana from the ForeverWar.]]
* PoweredByAForsakenChild: The Treasure Tool Trigger Happy, a weapon which forces a Flame Haze's Crimson Lord to manifest with his/her full power, killing the Flame Haze. Back in the 19th century, after his town was destroyed by a Flame Haze leading some Native Americans, the boy Billy Hawken worked with Friagne to kill that Flame Haze. Hawken was mortally injured, but his hatred for Flame Haze combined with Friagne's desire to kill them to form the ultimate anti-Flame Haze weapon. Friagne promptly used it to kill their target, and before dying Hawken named it Trigger Happy.
* PreviouslyOn: Every episode in the second season begins with Alastor summarizing the entirety of the previous episode. It gets rather egregious, especially when calling back to a {{Filler}} episode totally irrelevant to the current one.
* RankInflation: During a trip to an amusement park, Shana uses her powers to cheat at a swordfighting virtual reality game, maxing out the score counter and earning a rank of SSS.
* RapunzelHair: Shana
** [[spoiler:Yuji's as Snake of the Festival]] can shapeshift, but is usually kept about knee-length.
* Really700YearsOld: Except for the humans, most of the cast are centuries if not millenias, (Denizens don't exactly age and once you become a Flame haze you're immortal unless killed).
* RedHeadedHeroine: Shana when she activates her Flame Haze powers.
* RedOniBlueOni: Shana and Yuji.
* ReferenceOverdosed: The Shana-tan episodes are brimming with references to various media.
* {{Retcon}}: [[spoiler:Shana confessing to Yuji right before using the ForbiddenChekhovsGun]] at the (anime-original) end of the first season. The second season has him turning out to have not heard it, thus maintaining status quo.
* RetGone: Anyone or anything that loses its Power of Existence also has all evidence of its existence erased; photos, memories, records, all disappear. Objects usually remain, but have nothing tying them to the owner.
* RoaringRampageOfRevenge: The three remaining Four Gods of the Earth follow Shana in her assault on Bal Masqué in Misaki City to get revenge for [=CenterHill's=] death and to kill as many Denizens as possible for every human that had been devoured by a Crimson Denizen. Their goal is to turn the survivors of the battle, and battle itself, into a harrowing reminder for future Crimson Denizens as to what happens when monsters prey upon men.
* RomanticismVersusEnlightenment: Season 3 boils down to this: The Crimson Denizens are led by the cold and ruthless Enlightened [[spoiler:Yuji Sakai and the Snake of the Festival (who is inhabiting the former's body]], with a belief that UtopiaJustifiesTheMeans, who tries to create a world where the Crimson Denizens no longer have to consume humans to survive. Opposing them are Shana's and the Flame Haze's equally ruthless Romanticist [[AntiHero Anti-Heroism]] which will do anything for the sake of [[spoiler: protecting the balance which Denizens disrupt by consuming humans, even if it means occasionally using humans' Power of Existence themselves (though to be fair, Shana has, through Yuji's influence, made protecting humans a priority on par with protecting the balance). Shana and a small group of Flame Haze, eventually realizing that there was no way to stop the duplicate world Xanadu's creation after the Flame Haze were routed in a previous battle, attempt to insert a code into the device building Xanadu preventing Denizens from eating humans. They apparently achieve this until Yuji and the Snake of the Festival reveal that the device, while playing a ''role'' in the creation of Xanadu, was actually a decoy. A combination of the distortion energy collected by the [[{{MacGuffin}} Midnight Lost Child]] and their own power as the God of Creation was going to create Xanadu, and the code could easily be overwritten. However, the Denizens appeal to the Snake of the Festival to keep the code in anyways, and he agrees. So judging how Yuji and the Snake succeed in the end, this would make the series an Enlightened work.]]
** Actually, it appears that the work is a hybrid of Romanticism and Enlightenment. While the means of [[spoiler: Snake of the Festival Yuji]] and Bal Masqué are Enlightened, their motivations are a mixture of Enlightenment and Romanticism: a world where Denizens can fulfill their passions and desires being romantic; and Yuji's beliefs for a world where Flame Hazes, Humans and Crimson Denizens can coexist peacefully, the Crimson Denizens no longer have to consume humans to survive because they are given infinite power of existence, and the Flame Hazes can live normal lives, no longer just walking weapons, being enlightened. Also Romantic is ThePowerOfLove is what gives [[spoiler: Yuji]] the incredible determination and vision to actually end the millennia-old ForeverWar, and his primary motivation for ''changing reality itself'' is to create a world where Shana can be more than just a Flame Haze, i.e., an eventual, inevitable casualty of the war (and to protect humanity).
* SexyDiscretionShot: [[spoiler:When Margery and Keisaku have sex in the third season.]]
* SharingABody: [[spoiler:Yuji and Snake of the Festival]].
* ShipSinking: [[spoiler:Kazumi x Yuji]] didn't have much chance of happening anyway, but it was officially destroyed later in the novels when [[spoiler:Yuji]] finally made his move on [[spoiler:Shana]].
* [[SilenceYouFool Shut up (you fool)]], [[CatchPhrase Shut up (you fool)]], [[RuleOfThree SHUT UP (YOU FOOL)!!]]
* SittingOnTheRoof: Yuji and Shana, who at first is content to stay up there until Yuji invites her inside.
* SliceOfLife: It has moments. The beginning of season 2 is largely without conflict and instead focuses on the whole group's antics during normal life.
** Half the first episode. That is, until Shana comes.
* SlidingScaleOfIdealismVersusCynicism: The entire franchise. The world of ''Shakugan no Shana'' is a world where [[EldritchAbomination Eldritch Abominations]] known as Crimson Denizens, some of them [[PhysicalGod Physical Gods]] called Crimson Lords, secretly come to Earth to devour humans' Power of Existence, [[CessationOfExistence erasing them from existence]]. This causes the balance between Earth and the Denizens' point of origin, the Crimson World, to be damaged, threatening to destroy both worlds. They are opposed by Flame Haze, former humans commissioned by other Crimson Lords to protect the balance. However, most of these Flame Haze are [[KnightTemplar Knight Templars]] who at best [[LawfulNeutral prioritize preserving the balance over human lives]] and at worst are [[SociopathicHero sociopaths]] who seek to [[RoaringRampageOfRevenge get back at Denizens for having been wrong by them in the past.]] The Flame Haze's belligerent nature and differing motivations means that they rarely work together, forming large groups only in the face of existential threats. Otherwise, they fight each to the point of near death. Oh, and they won't hesitate to use humans' Power of Existence to repair damage caused by the war. Additionally, the Flame Haze can only delay the inevitable, limiting the damage but not preventing or eliminating it entirely. This dark, cynical environment is counterpointed by the protagonists Shana and Yuji, who believe that Flame Haze can be more than just walking weapons, but people with a reason for being beyond their mission or revenge. They believe that with ThePowerOfLove, they can protect those they care about, overcome impossible odds, and forge a lasting relationship between the two of them. Yuji is even more idealistic, envisioning a future where Flame Haze, Denizens, and humans can coexist. As for Shana, [[spoiler: after Yuji joins the enemy Bal Masqué in order to realize this dream, she refuses to even consider killing Yuji, confident that she can both fulfill her duty as a Flame Haze and [[ICanChangeMyBeloved redeem Yuji.]]]] Ultimately, it is their idealism that triumphs over the cynicism of the setting.
* SmallNameBigEgo: The Four Gods of Earth. Despite their names, none of the four Crimson Lords affiliated under this group are real Gods of the Crimson Realm like Alastor, the Snake of the Festival, and Shaher.
* SpellMyNameWithAnS: Wilhelmina's name is spelled and pronounced "Wirhelmina" in the dub.
* SphereOfDestruction: Robots that Dantalion deploys in the final battle can [[SuicideAttack blow up and vaporize everything]] [[InstantDeathRadius in a 30-meter radius]].
** [[spoiler: [[HoistByHisOwnPetard Said robots end up being Danatalion's undoing.]]]]
* SplitPersonalityTakeover: [[spoiler: Averted. While it seems that way early on, the Snake only ever comes out to talk with the rest of Bal Masque. Yuji's the one doing all the fighting]]
* StoryBreakerPower: The Snake of the Festival [[spoiler:Yuji]] is the God of Creation, whose power equals Alastor's, and he seems to have no problems showing off: infinite power, Prehensile Hair, and a sword that [[spoiler:causes anyone who tries blocking it to sustain heavy injuries (Blutsager)]]. Plus the whole "Creator" bit.
* StockSoundEffects: Paying close attention will reveal the "de-rezzing" sound from ''Tron'' and the good ol' proton pack charge-up sound from Film/{{Ghostbusters}}.
* SurprisinglyGoodEnglish: ''I'll Believe'' by ALTIMA, the ending to the third season, has a 45-second intro and several lines sung in almost-perfect English. [[CrowningMusicOfAwesome And then]] [[InitialD there's motsu]]. [[http://www.youtube.com/watch?v=qawCrrKe62Y Check it out]].
* SweetTooth: Shana, if her eating ''two'' [[GiantFood super duper extra ginormous servings]] of ice cream sundae is any indication (One is almost as tall as she is!). Her thing for melon bread may also count. She also consumes a "couple dozen" ice cream bars during the Shana S ova and thinks that Yuji's body is weak for getting sick afterward.
* TakingTheBullet: [[spoiler:Shana intercepting Wilhelmina's spear after Yuji gets captured. She's a Flame Haze, though, so she's good to go again after a little time off to heal.]]
* TheTalk: Averted.
-->'''Shana''':What's wrong? [[spoiler:Chigusa]]'s having a baby, right? Teach me how to make one.
-->''(camera pans across the shocked faces of the Sakai family)''
-->'''Yuji''' ''(blushing)'': ...eh-heh...
-->'''Kantarou''': ...we can't teach you without other people's consent... right Chigusa-san?
-->'''Chigusa''': ...yes, we need to speak with Carmel-san and Arasu-Touru-san...
* ThemeNaming: All of the beings from the Crimson World in ''ShakuganNoShana'' take names out of various mythologies. Just to name a few: there's the "[[MadScientist Seeking Professor]]", [[http://en.wikipedia.org/wiki/Dantalion Dantalion]]; Margery's battle-hungry lord, [[http://en.wikipedia.org/wiki/Marchosias Marchosias]]; and Shana's lord, "God of Atonement" and "Flame of Heaven", [[http://en.wikipedia.org/wiki/Alastor Alastor]].
* TheWorldIsAlwaysDoomed: They practically come out and say this (with regard to existence), making the ''second'' episode of the show a WhamEpisode.
* TheyCallHimSword: 'Shana' comes from the name of her sword, Nietono no Shana.
* ThirdOptionLoveInterest: Fumina Konoe
* ThroughHisStomach: Kazumi to Yuji. Shana soon catches on.
* TimeStop: See PhantomZone, above. [[AllThereInTheManual Time doesn't]] ''[[AllThereInTheManual really]]'' [[AllThereInTheManual stop]], but it's a convincing impression, with everything frozen in place and recast in gray.
* TooGoodForThisSinfulEarth: Yuri, in Margery Daw's flashback. Unlike all other Flame Haze, who are hellbent on vengeance and killing Tomogara, Yuri, a young boy, just wants to save people and seems to completely lack fighting spirit. [[SarcasmMode I mean, ''really'', what self-respecting Flame Haze actually cares about ''humans''?]]
* TookALevelInBadass: [[spoiler:Yuji,]] in Season 3. [[spoiler:Sure he did improve in his fighting skills in Season 2 of the anime, but it wasn't until Season 3 that he truly proved to be a formidable opponent. From simply aiding Shana in her fights to being so strong that few people can even hit him (at first), he really lived up to the trope's name.]]
* TrademarkFavoriteFood: Melon bread, for Shana. Anything with alcohol for Margery.
* TragicVillain: [[spoiler:Yuji becomes this after becoming the Snake of the Festival]]
* TheTropeWithoutATitle: Just about all Tomogara and Flame Haze.
* {{Tsundere}}: Fans consider Shana to be the [[Pantheon/{{Emotion}} goddess]] of this trope.
** Shana essentially started her own type of tsundere, that is much more 'bipolar' than the classical tsundere. Later incarnations of this trope are described as '[[ShanaClone Shana clones]]'.
*** Ironically, the clones often lack the character development that softened (relatively) Shana as the story went on. She's still a {{Tsundere}}, but much less "bipolar".
* VerbalTic: Wilhelmina ends nearly every sentence with "de arimasu", an archaic form of "desu" usually restricted to writing ~de arimasu. It gets a little annoying ~de arimasu.
** This was changed to 'indeed' in the dub. And you thought [[Series/StargateSG1 Teal'c]] used the word a lot.
* VoicesAreMental: This is averted in the Shana S [=OVAs=] where Yuuji and Shana swap bodies. They still talk like themselves, though of course some effort was made by the [=VAs=] to mimic each other's tones and speech patterns.
* WellIntentionedExtremist: [[spoiler:The Flame Haze and Yuji. The entire war is an example of GreyAndGrayMorality.]]
* WhamEpisode: Volume 16: [[spoiler: Yuji is now the BigBad.]] And another in Volume 22, the final light novel: [[spoiler:Yuji wins, but the Crimson Denizens decide to compromise with the Flame Haze and allow their paradise, Xanadu, to have a built-in limit preventing them from devouring humans' Power of Existence]].
* WhatHappenedToTheMouse: The opening scene from ''Final'' never ended up happening, much like the opening scene of TengenToppaGurrenLagann.
* WhenTheClockStrikesTwelve: The [[MeaningfulName Midnight]] Lost Child refills the bearer's power of existence every midnight. It apparently makes its own time zone adjustment, since it was created in Europe.
* WillTheyOrWontThey: Yuji and Shana.
** [[spoiler: TheyDo - Shana and Yuji end up romantically involved by the end of the series.]]
* YourMindMakesItReal: See AllJustADream, above. Also, if the dreamweaver dies, it's NonstandardGameOver for everyone inside.
