[[caption-width-right:350:Hagi and Saya, with a Chiropteran in the background.]]
Saya Otonashi is seemingly an OrdinaryHighSchoolStudent in Okinawa, aside from her amnesia and anemia. All she wants is to compete in track and spend time with her American adopted father George and her (also adopted) brothers, moody Kai and innocent Riku. However, Saya's world changes forever when she's attacked by a Chiropteran, a hulking, bat-like humanoid monster. This prompts a rescue by Hagi, a mysterious, handsome [[TheStoic stoic]] who seems devoted to protecting Saya. Hagi kisses Saya, forces her to drink his blood, then gives Saya a sword coated with her own blood. This event cause a strange transformation in Saya; her eyes glow red and she becomes a fighting machine, quickly killing the Chiropteran. Afterwards, answers are refused while even more strange accidents occur all around Saya; eventually, she is forced into leaving her home to help a secret organization called Red Shield stop a mysterious entity only known as Diva. However, not everything is black and white, and Saya soon begins to doubt her reasons to fight, her allies, and her own humanity.

''Blood+'' is a 50 episode long anime which is loosely based on the OAV ''Anime/BloodTheLastVampire''; the film and the series share the basic premise, the characters of Saya, David and Lewis (all of whom are re-imagined in ''Blood+''), and the Chiropterans, but otherwise have little in common.

If you live in North America, you can watch this series on Crackle ([[http://www.crackle.com/c/blood Here]]), Hulu ([[http://www.hulu.com/blood Here]]), and Website/YouTube ([[http://www.youtube.com/verify_age?next_url=/watch%3Fv%3D38nqabw7I58 here]]).

----
!!Tropes:

* AbnormalAmmo: The ignition rounds Kai uses latter in the series. Shooting explosive rounds into a Chiropteran followed by a primer shot made the guns suddenly become slightly less useless.
* AbsurdlySharpBlade: [[ManOfWealthAndTaste Solomon Goldsmith]] has a BladeBelowTheShoulder capable of cutting through cliffs and the limbs of [[NighInvulnerable Chevaliers]]. This includes the arm of [[spoiler: James]] who sports extremely powerful [[spoiler: InstantArmor]].
* AchillesHeel: Chiropterans will be petrified if exposed to the blood of the rival Queen.
* ActionDressRip: [[spoiler:Saya and Diva during their final confrontation.]]
* ActionGirl: Saya, although reluctantly at first. Lulu on the other hand finds fighting fun.
* AdaptationExpansion: Blood+ Adagio and City of Night Walkers. Also the Light Novels to an extent.
* AdaptationPersonalityChange: Most of the characters in the manga.
* AffablyEvil: Solomon may be one of Diva's henchmen, but he's a pretty decent guy overall. He's a peace loving person, and actually cares for his chiropteran "brothers." Nathan as well; in fact, he's more affable than evil.
* AllLoveIsUnrequited: Solomon for Saya, Karl for Diva and then Saya, possibly Kai for Saya, Mao for Kai (at first). The list goes on.
* AlternateContinuity: The series' relationship to ''BloodTheLastVampire''. Also, the manga's relationship to the series.
* AlwaysIdenticalTwins: Chiropteran queens are always born in pairs, one sporting red eyes and the other blue. Aside from that, they're completely identical.
* AmbitionIsEvil:
** [[spoiler: Collins' entire reason for betraying the Red Shield for Diva's group was because he wanted to make his findings about chiropterans public, which the Red Shield refused to let him do.]]
** Everything Amshel does is because of his desire to find out everything he possibly can about chiropterans, and if that means overstepping all kinds of moral bounds and nearly causing TheEndOfTheWorldAsWeKnowIt, it's a small price to pay.
* AmericaSavesTheDay: Subverted; though many of the central characters are Americans, the American military and government as a whole is not depicted as benevolent or well intentioned.
* AmnesiacDissonance: Saya
* AnAsskickingChristmas: A darker example than most; Saya's Vietnam War [[UnstoppableRage massacre]] happened on Christmas Day.
* AnAxeToGrind: Lulu
* [[AnimalsHateHim Animals Hate Her]]: Poor Saya
* AntiVillain: Solomon is the most obvious example. Nathan also can be seen this way, though really his true motivations and goals are so murky that he's pretty hard to pin down.
* AnyoneCanDie
* ArmiesAreEvil: Especially the Americans...
* ArmCannon: A biological variant. The Schiff and people with Schiff limbs grafted on can launch crystal spikes.
* ArtificialLimbs: Karl got a mechanical replacement for his injured right arm after UsefulNotes/TheVietnamWar. Later on he and [[spoiler: James]] would get Schiff limbs attached to replace limbs they had amputated.
* ArtShift: The third opening sequence.
* AudibleSharpness: When Saya primes her katana with blood
* BabiesEverAfter: [[spoiler: Julia]] in the finale
* BadassAdorable: Lulu wields an oversized axe and fights monsters with ease, but is still a young girl who likes watching children's cartoons.
* BadassInANiceSuit: Chevaliers in general and David. Considering how often these clothes get destroyed, one wonders how much of their budget Red Shield and Cinq Fleche earmark for new suits.
* BadassLongcoat: Hagi in "City of Nightwalkers"
* BadassNormal: Kai, David, Lewis
* BavarianFireDrill: How Okamura planned on infiltrating the Cinq Fleches dance, by abusing his press pass and looking like he was supposed to be there. It didn't work.
* BattleCouple: Hagi and Saya. They also share at least one BackToBackBadasses pose.
* BeePeople: The Chiropteran 'Queen' reigns over her drone-esque Chevaliers.
* BeenThereShapedHistory: Though they didn't directly influence it, both the Red Shield and Diva's group were involved in the Vietnam War.
* BeethovenWasAnAlienSpy: Rasputin and Martin Bormann were Diva's Chevaliers
* BerserkMode: Saya during the Vietnam War. [[spoiler: Turns out it's not wise to wake a Chiropteran queen early from her long hibernation mode.]]
* BigAppleSauce: The final ten or so episodes, [[spoiler: as well as Saya and Diva's final showdown]], are set in UsefulNotes/NewYorkCity.
* BigBrotherInstinct: Kai for Saya and Riku. [[NotBloodSiblings Well, with some confusion related to his feelings for Saya]].
** Solomon for Karl as well.
* BigDamnHeroes: Hagi pulls this off quite a bit with Saya.
* BigEater: Both Lewis and--believe it or not--Saya
* BigScrewedUpFamily: Diva and her Chevaliers, which is a sharp contrast to Saya's relationships with her family [[spoiler:and later the Schiff]].
* {{Bishonen}}: Hagi and Solomon. Kai also counts.
* BittersweetEnding: True, Diva is defeated and the Chiropteran threat has been ended, and Saya can finally live her life without fighting and killing. Unfortunately, she'll have to go through thirty years of hibernation first, and will miss out on a lot of the lives of her family and friends in the process.
* BlackAndGreyMorality: Diva and her group vs. the Red Shield.
* BladeBelowTheShoulder: Solomon's signature weapon; played with in that the blade ''is his arm.''
* BloodIsTheNewBlack[=/=]BloodSplatteredWarrior: Saya. Seriously, you could count the number of times she ''hasn't'' been drenched in her foes' blood or her own on one hand.
* BloodSplatteredInnocents
* BloodyMurder: Chiropteran Queens and Chevaliers
* BodyHorror: Humans transforming into Chiroptera and/or Chevaliers, and the effects of the Thorn. Also, [[spoiler: the Vietnamese test subjects.]]
* BodyguardCrush: Hagi's love for Saya
* BoisterousBruiser: George. He even punched a Chiropteran in the face!
* BoomerangBigot: Saya has little more than disdain for most other Chiropterans despite being one herself. Shown more prominently in the manga; she even explicitly tells Riku, her own little brother, that she's going to eventually kill him just for being a Chiropteran.
* BrattyHalfPint: [[spoiler: Hagi]] when he first met Saya. Granted those circumstances would make anybody grumpy.
* BreathWeapon: One of Amshel's powers.
* BringMyRedJacket: Saya constantly wears a dark red leather coat after the TimeSkip.
* BrokenPedestal: [[spoiler: Collins for Julia.]]
* BrotherSisterIncest: Kai has a definite thing for Saya, though nothing ever comes of it. And granted, they're NotBloodRelated, but still.
** Also, technically speaking, [[spoiler: Diva's rape of Riku, seeing as he's the adopted brother of her identical twin sister.]]
* BreakTheCutie: Saya gets broken ''twice'' thanks to her amnesia.
** And how about [[spoiler:Riku]]? Sucks to be him.
** Also, Hagi. Through a flashback, [[spoiler: it is shown that the reason he went from being somewhat stoic to made of stone was because his blood turned his OneTrueLove and reason for living into a murdering psychopath who forgot who he was and cut his arm off during her rampage.]]
* BreatherEpisode: The return to Okinawa after Vietnam and the shopping trip in New York.
* BrownNote: Diva's singing can get deadly under the right circumstances
* BuryYourGays: Subverted in that [[spoiler:Nathan survives 'til the very end, outliving his boss, associates, underlings and several main characters. After Saya ''cuts him in half.'']] He makes a passing statement that implies [[spoiler:that he is not actually Diva's chevalier, but the chevalier of Saya and Diva's ''mother'']]. Saya's blood might not have ever been a threat to him. If this is true, [[spoiler:Nathan would be completely impossible to kill, unless Saya and Diva's aunt (who must have existed since Chiropteran queens are always twins) is still out there somewhere]].
** [[spoiler: He's killed in the manga after he murders Diva due to pent up rage from Diva's indifference over James' death]].
* ButNotTooForeign: A non-human example. Saya was born and raised in France, but can easily pass herself off as a native Okinawan.
* CallBack: In the beginning, David ruthlessly beats up Kai, who attacks him out of mere instinct, to show the CrapsackWorld Chiropteran survivors and their fighters live in. During [[spoiler:David's HeroicBSOD]], Kai returns the favor and says the [[IronicEcho exact same words]].
* CainAndAbel: [[spoiler: A gender and age inverted example.]]
* {{Camp}}: Karl's Phantom costume.
* CampGay: Nathan is the gayest thing since gay came to Gaytown: voice, wardrobe, hair, he is a fashion designer, he works in musical theater...
** And yet it's revealed [[spoiler:that he's one of the most powerful chiropterans in the series; even Amshel doesn't dare push him too far.]]
* CharacterDevelopment: Kai evolves from an EmoTeen to a mature, confident hero. Saya and Hagi get a bit as well
* ChildrenAreInnocent: Riku. Face it, if Kai was the one who [[spoiler: had his blood drained by Diva and became Saya's Chevalier only to get raped and killed by Diva]], it wouldn't be quite as traumatic for the cast or the audience.
* CleanCut
* CloneArmy: The Corpse Corps are clones of the Schiff Moses.
* ConcertKiss: Happens between Hagi and Saya.
* CoolBoat: Red Shield's headquarters
* CorruptCorporateExecutive: Amshel Goldsmith and Van Argeno
* CrapsackWorld: Wherever you are, a nearly NighInvulnerable Chiropteran could appear and attack you. Whether hiding as a person you know or out in the open at night. If you're lucky, one of them could be a Chivailer of an EvilDiva who runs rampant when she's awake. Furthermore, you yourself could turn into a Chiropteran just by taking an everyday food produced by a massive MegaCorp run by these things. Worse yet, they have full backing from the U.S. military and do will do their best to eliminate you if you get too close. If you're lucky to survive, your only way of fighting them is Saya, who is retains having an {{Angst}} personality and will only side with you normally every thirty years. The other option is Red Shield, which is reluctant to accept those who slow their fight against the Chiropterans.
** If you want a simpler description of this world, try fighting [[GoodIsNotNice David]] with mere instinct, then have him mercilessly beat you up for it.
* CreepyChild: Err, well creepy Vietnamese children who were exposed to Delta 67. [[spoiler: The end result was mini chiropterans.]]
* CrouchingMoronHiddenBadass: Nathan.
* CryForTheDevil: [[spoiler: Diva. As Nathan puts it when she dies: "Poor girl...she just wanted to have a family..."]] Also Karl, possibly.
* CuteAndPsycho: Oh God, Diva.
* CuteLittleFangs: Saya and Riku, especially in the manga.
* DarkSkinnedBlond: Monique
* DavidVersusGoliath: Diva's Chevaliers are more powerful than Saya's as the former receive more blood.
* DeadlyDodging: Standard fare whenever two Chevaliers fight. Hagi and Karl's first fight in particular.
* DeathByAdaptation: Nathan and Mui in the manga.
* DeathSeeker: [[spoiler: Karl, and Saya. Indeed, until the very end, Saya intends to kill Diva and then herself, but Hagi and Kai manage to convince her not to.]]
* {{Delinquents}}: Kai and Mao before they got caught up with Red Shield.
* DeliberateInjuryGambit: [[spoiler: Saya's final defeat of Karl.]]
* [[spoiler: DeliverUsFromEvil: Thoroughly averted.]]
* DeusExMachina: The final battle with [[spoiler: James. Sure, it makes sense that he would be afflicted by Thorn with his Schiff grafts, but the timing was just a ''little'' too convenient for our heroes...]]
* DiagonalCut: How Saya dispatched a lot of Chiropterans over the course of the series.
* DoubleStandardRapeFemaleOnMale: Completely [[spoiler:averted with Diva and Riku]].
* DramaPreservingHandicap: [[spoiler:For her final confrontation with Diva, Saya was being gradually weakened since she was starting to enter her hibernation cycle]]. If not for that her superior fighting skills would have ended the fight in seconds.
* DressHitsFloor: The pivotal scene between [[spoiler: Diva and Riku]] in the episode 'Boy Meets Girl'.
* DrowningMySorrows: David, after the MoralEventHorizon tragedy listed below
* DudeShesLikeInAComa: A gender averted example. Julia kisses David this way while he's injured at a hospital.
* DyingAsYourself: [[spoiler: George asks Saya to finish him off before the Delta 67 in his system completely turns him into a Chiropteran.]]
* {{Eagleland}} Flavor 2: The American government is just downright '''EEEEVIL''' in this one
** Which is funny, considering how many of the good guys are American.
* [[spoiler:EarnYourHappyEnding]]
* EmergencyTransformation: Happens to [[spoiler: Riku]]
** [[spoiler: And Hagi.]]
* EvenTheGirlsWantHer: Saya. Poor Saya.
* EvenTheGuysWantHim: In the novels Kai muses to himself that even guys like him wouldn't be able to deny how attractive [[TallDarkAndHandsome Hagi]] is.
* EvilutionaryBiologist: Cinq Flèches.
* [[spoiler:EvilKnockoff: The Corpse Corps. See PsychoRangers below for details.]]
* [[spoiler:EvilTwin: Diva. Justified because of her upbringing.]]
* ExoticWeaponSupremacy: The Schiff.
* ExtremeDoormat: Hagi, until late in the series
** Subverted. All of the Chevaliers appear to be Extreme Doormats, but they actually aren't. Ultimately, Hagi wants to fulfill Saya's wish, but he doesn't coddle to her every whim and is perfectly capable of disagreeing with her in order to protect her. The other Chevaliers are almost the opposite. They spoil Diva by giving her every little thing she wants, but they are primarily motivated by selfishness and continually manipulate her for their own benefit.
* EyeScream: Hagi stabs a Chiropteran in the eye in the first episode.
* FaceHeelTurn: [[spoiler: Dr. Collins betrays Red Shield to work for Cinq Fléches, taking Julia with him. Julia eventually [[HeelFaceTurn]] rejoins Red Shield, with some prodding from David.]]
* FaceStealer: Chevaliers and Queens have the ability to take the form of somebody whose blood they have drunk. Diva uses it for extra {{Squick}} when she goes around looking like [[spoiler: Riku]].
* FantasticRacism: James' hatred of the Schiff. Particularly ironic, given that he is a black American. [[spoiler:Becomes even more ironic when James is saved from certain death...by replacing most of his body with Schiff parts.]] Of course, this makes it ''worse''; [[spoiler:self-hatred makes him lash out, and he blames the Schiff for the fact that Diva is disgusted with James's own Schiff transplants.]]
* FauxAffablyEvil: Diva.
* FeedTheMole: [[spoiler: Amshel tells [[TheMole Solomon]] Diva will be at Christina Island to shoot a video in a week. The latter told Red Shield, who arrived on the island. By that time, Diva left the island. James was waiting for them.]]
* FiveBadBand
** BigBad: Diva
** TheDragon / EvilGenius: Amshel Goldsmith
** TheBrute: James Ironside and Karl Fei-Ong
** DarkChick: Nathan Mahler
** TheDragon/ [[spoiler:SixthRangerTraitor]]: Solomon Goldsmith
** TokenHuman: Van Argeno
* FlamboyantGay: Nathan Mahler, but boy is he dangerous
* FlashBack: Many scattered throughout the series, with a few [[WholeEpisodeFlashBack episodes flashing back to Saya and hagi's past]]
* FlashStep: Chevaliers, Queens, the Schiff and Corpse Corps.
* FlechetteStorm: Karl's [[spoiler: Schiff]] arm allows him to rapidly fire huge spikes from his hand.
* FluffyTheTerrible: The Delta-67 strain Chiropterans are referred to as "mice".
* ForScience: [[spoiler: Amshel's ultimate motivation behind being Diva's Chevalier and the Delta-67 project is because he wants to better study Chiropterans.]]
* ForWantOfANail: [[spoiler: Saya and Diva are twin sisters. Joel raised Saya like a daughter, whereas Amshel kept Diva locked in a tower, treating her like an experiment. When Saya receives this history lesson, she can't help but sympathize with Diva, knowing full well that they could just as easily wound up with their roles switched.]]
* FreudianExcuse: Diva's so fucked up because [[spoiler: she spent her life as a test subject locked in a tower. And only received anything like human contact from a person that saw her as a specimen. Her feud with Saya stems from the fact that she seeks revenge for how their adoptive father, the first Joel Goldschmidt, callously neglected her at the same time he raised Saya in freedom and luxury.]]
* GenkiGirl: Lulu
* GeniusSweetTooth: Van Argeno regularly eats hard candies.
* GetAHoldOfYourselfMan: Kai tries to snap David out of his Heroic BSOD after [[spoiler: Red Shield's HQ sunk]] by pouring out his booze and punching him in the gut.
* GlowingEyesofDoom: Chiropterans in general gain glowing eyes when they get serious.
* GoGoEnslavement: After losing consciousness because of a fight, Saya is abducted by [[StalkerWithACrush Solomon]] and stripped of her clothes in her sleep. He claims it was because they were ruined. However, he gives her a nice gown after she does wake up.
* GoOutWithASmile: Diva's dying act is to smile at and caress her cocoons of her unborn daughters.
* GoodColorsEvilColors: Inverted, red is Saya's color and blue is [[BigBad Diva's]]
* GoodOldWays: Hagi, and [[spoiler: Riku once he becomes Saya's Chevalier]], if only in clothing styles.
* GoodIsNotNice: David certainly counts, at least early on. He beats Kai senseless to teach him a lesson on what kind of world they live in and forces Saya to fight despite full knowledge that it's tearing her apart.
* GoodThingYouCanHeal: Sapient Chiropterans in general. Saya takes advantage of it in a battle against Karl [[spoiler:running herself through to stab Karl and poison him with her blood]]. Diva once got shot on purpose just so Amshel would buy her a new dress. And Hagi seems to get ImpaledWithExtremePrejudice at least every other fight.
* GunsAreWorthless: Bullets might slow a Chiropteran down, but to kill them you need Saya -- or at least her blood. Beheading and incineration also work, but these aren't exactly things that can be accomplished with firearms, and are generally nigh-impossible for ordinary humans to pull off anyway.
** Encasing them in concrete and sinking them to the bottom of the ocean seems to be the preferred method of dealing with them semi-permanently. Of course, this only works if you can manage to trap them into a strong cage before pouring in the concrete.
*** With the ignition rounds that Kai uses after the TimeSkip, they become slightly less useless in a fight.
* HappilyAdopted: Saya, Kai and Riku when living with George. [[spoiler: Too bad it didn't last.]]
** [[spoiler: In the epilogue, Diva's children living with Kai.]]
* HappinessInSlavery: For at least the first 2/3 of the show, Haji embodies this trope perfectly: a servant that is completely and utterly loyal to his master, because as a chevalier he's biologically hardwired that way. Then it turns out that chevaliers can betray their queens and abandon them without remorse; Haji is simply ''that'' devoted to Saya.
* HealingFactor: Saya's wounds are known to heal exceedingly fast, along with Hagi- though their rapid healing rate is only based on the amount of blood they consume. i.e. Saya's wounds will heal more rapidly after drinking human or Hagi's blood, and Hagi's wounds will heal after drinking human blood.
* HeelFaceTurn: [[spoiler:the Schiff, and later Solomon Goldsmith.]]
* HeroicBSOD: Saya and David, after Diva's mid-series MoralEventHorizon moment. David spends the TimeSkip and several episodes after it as a [[DrowningMySorrows drunken mess]], and Saya attempts to distance herself from her friends and family to avoid the pain of losing any more loved ones. Both eventually snap out of it.
* HeroicWillpower: Saya managed to hold back her approaching hibernation cycle long enough to [[spoiler: kill Diva]] and [[spoiler: return to Okinawa]].
* HesBack: David, after he's finished [[DrowningMySorrows drowning his sorrows]]
* HeroSecretService: Red Shield for Saya.
* HighPressureBlood
* HopeSpot: Saya, Kai, and Riku play a game of catch as the sun sets. They talk about going home to Okinawa together, when all is said and done. [[spoiler:Moments later, Diva shows up and... [[RapeDiscretionShot oh]] [[KillTheCutie God...]]]]
* HotScientist: Julia
* IAmNotLeftHanded: [[spoiler: Hagi]] [[WillfullyWeak deliberately]] keeps the full extent of his Chevalier abilities in check because of Saya's horror when she first saw him use them, but will go all-out [[GodzillaThreshold when the situation demands it.]]
* ICannotSelfTerminate: [[spoiler:Saya]], resulting in her promise with [[spoiler:Hagi]].
* IdiotBall: Early in the series, Kai follows Saya to Hanoi after getting his ass handed to him by a simple Red Shield operative, and being shown that he would be worse than useless in a fight against the supernatural fiends Saya fights on a day-to-day basis. Even worse, he drags their younger brother along with him. He then proceeds to barge in during the middle of a dangerous fight and purposefully snaps her out of berserker mode [[strike:for no apparent reason]] because he can't stand to see his adoptive imouto Saya as a bloodthirsty killing machine.
* IfICantHaveYou
* ImmortalLifeIsCheap: Oh, Hagi. He seems to get a bloody impalement once every battle.
* ImmortalityBeginsAtTwenty: [[spoiler: Saya and Diva]] stopped aging when they turned sixteen.
* ImplausibleFencingPowers: Karman has blocked a bullet from David in a fight.
* ImpaledWithExtremePrejudice: Happens to Hagi repeatedly. Also [[spoiler: Amshel,]] who got impaled by the spire on top of the Chrysler Building. He got better, at least for enough time to get himself KilledOffForReal.
* ImprobableWeaponUser: Hagi goes around hitting people with a ''cello case''. With ''a cello in it.''
* InLoveWithYourCarnage: Karl to Saya (and Diva, it's implied) in the anime; Solomon to Saya in the manga
* InstantArmor: James' most prominent ability, in the form of nigh indestructible skin.
* InTheHood: The Schiff when first introduced.
* InstantExpert: Saya is initially confused by her sudden aptitude for sword fighting and languages. Subverted in the fact that she isn't learning new skills, just remembering ones she already had.
* InstrumentOfMurder: Hagi borders on this trope. He regularly uses his cello ''case'' as a weapon/shield. The cello itself is only used to perform music. One does have to wonder how it hasn't been smashed to pieces inside his case though.
* IntimateHealing: To heal, queens recieve blood from their Chevaliers. This is typically a fairly intimate process. See also KissOfLife, below.
* IntrepidReporter: Okamura.
* IronicEcho: After a BadassNormal CurbStompBattle, [[CrapsackWorld "This the world we live in."]]
* ItsAllMyFault: Saya's word-for-word reaction when she remembers that [[NiceJobBreakingItHero that she was the one who set Diva free in the first place]].
* IWorkAlone: Saya develops this attitude after the TimeSkip as part of her HeroicBSOD, refusing to work with her pals in the Red Shield because she doesn't want to endure the pain of losing any more friends and loved ones. She snaps out of it eventually.
* KatanasAreJustBetter: For Saya anyways, since it has a groove etched into it to keep her blood applied longer.
* KillTheCutie: [[spoiler:Riku]]
** [[spoiler: first [[SubvertedTrope subverted]], given that one does not expect Riku to survive his first encounter with Diva, then tragically [[TheUntwist untwisted]], given that one does expect him to survive his second encounter with her.]]
** Averted in the manga [[spoiler: where he lives]].
** [[spoiler: Charles]] in the manga.
* KissOfLife: Played with; to awaken Saya's Chiropteran powers to save her from the first Delta-series Chiropteran she encounters, Hagi gives her some of his blood by putting it into his mouth and kissing her. [[spoiler: This is later revealed to be a sort of MeaningfulEcho of how she turned him into a Chevalier in the first place, giving him some of her blood to save his life after he fell off a cliff-which ironically was her fault, since she tried to grab a flower over the edge just to give it as a birthday present to the first Joel.]]
* KissOfTheVampire: Several of the reactions, Nathan's in particular, suggest that a queen's bite can be quite... pleasurable.
* KnifeNut: In addition to his cello case, Hagi has a seemingly unlimited supply of throwing knives.
* LaserGuidedKarma: Played straight for both sides. In their final showdown, [[spoiler: Diva and Saya stab each other with their blood, which normally would have killed both of them, but Saya survives because Diva's pregnancy made her blood lose its potency]].
* LastOfHerKind: [[spoiler: Lulu, the last survivor of the Schiff.]]
* [[spoiler: LeaveYourQuestTest: In 1900's Russia, with the chevalier girl tempting Saya.]]
* LifeOrLimbDecision: Karl realized he could stop the [[TakenForGranite petrification from Saya's blood]] by cutting off his limb before it spread.
* LightIsNotGood: Solomon, who wears white and has an angelic appearance ([[spoiler:that is, until he leaves Diva's side]], however, even that has nothing to do with any sense that [[spoiler: trying to kill off all or most of humanity is ''wrong''. He just decided that he liked Saya more]].
** Diva as well. Pale pretty girl with blue eyes, wears white Victorian clothing, is a opera singer and often described as a angel. Bad side? [[spoiler:She is a century and a half old Chiropteran Queen who has killed thousands of people, participated in a experiment to create a virus to turn others into chiropterans, had figures such as Gregory Rasputin and Martin Bormann as her chevaliers, meaning she was involved in, if not being the mastermind of, the Romanov Massacre (As she also impersonated Anastasia) and WWII. Should I also mention she raped a 14-year old boy to get pregnant and then killed him, all for the sake of pissing off her sister? Also, when she sings, people turn into monsters.]]
* LighterAndSofter: The manga - pretty much nobody dies, in stark comparison to the anime.
** Also DarkerAndEdgier in the sense that it is more perverted (inappropriate panty shots abound) and there is plenty of nasty gore.
* TheLoad: Played straight and averted with Kai and Riku. At the beginning of the series, neither have much fighting skill and mostly hindered Red Shield. On many occasions, though, they gave Saya some required emotional support in order to fulfill her tasks. After the [[spoiler: [[TimeSkip destruction of Red Shield]]]], Kai trains and becomes an important part of the team, being able to fight as well as counsel those in distress.
* LockedOutOfTheLoop: Saya until the Zoo arc.
* LuckilyMyPowersWillProtectMe: [[TemptingFate James taunts Saya]] about how her blood can't poison him if she can't pierce his armored skin.
* MadeOfIndestructium: What {{fanon}} believes Hagi's cello is made of. Otherwise it should have been smashed to pieces hundreds of times over while he is using his cello case as a weapon.
* MadScientist: [[spoiler:Amshel]] is a combination of this and CorruptCorporateExecutive.
** Cinq Fleche employs a few of others such as Boris (creator of the Schiff) and Van (who worked to perfect Delta 67)
* MajorInjuryUnderreaction: Avoided. Several [[GoodThingICanHeal Chevaliers]] avoid any major reactions when they undergo injuries. These injuries include [[spoiler: Solomon and Hagi]] having arms sliced off and Solomon having a giant hole ripped through his stomach. However, many of these aren't major injuries in the first place as they [[HealingFactor heal extremely quickly]].
* [[ManOfWealthAndTaste Men Of Wealth And Taste]]: Diva's Chevaliers.
* MayContainEvil: Cinq Fleche distributed a bunch of food products laced with Delta 67.
* MeaningfulName:
** The Schiff who led the others out of captivity is named [[Literature/TheBible ''Moses'']].
** [[LukeNounverber James Ironside]], a MightyGlacier with NighInvulnerability.
** Possible example with the name Hagi. In Japanese 'Haji' can mean 'shame' or 'guilt'. [[spoiler: This is meaningful as it is a possible explanation for why he becomes such a [[TheStoic Stoic]] after the Vietnam incident. Indeed, WordOfGod states that feeling responsible for what happened is the reason he is a more subdued character by the time Saya meets him again in the first episode.]]
* MegaCorp: Though Cinq Flèches is largely described as a pharmaceutical enterprise, it has enough resources to be active in other industries, such as technology, food production, military contracting, and, of course, Chiropteran-based genetic manipulation. They even own and run an all-girls high school in Vietnam.
* AMillionIsAStatistic: People didn't start to lose sympathy for Diva, despite the hundreds of people she killed, [[spoiler: until ''after'' she raped and killed Riku.]]
* MistressAndServantBoy: [[spoiler:Hagi and Saya's]] relationship began this way.
* MortalWoundReveal: Following a lengthy fight, [[spoiler: Solomon]] rips open a small cut on his clothing. Turns out a small wound with Saya's [[BloodyMurder blood]] was enough to make his body [[TakenForGranite slowly crystallize and crumble]].
* MotorcycleOnTheCoastRoad
* MurderTheHypotenuse: What Solomon would love to do to Hagi.
* MusclesAreMeaningless: Both Saya and Diva are tiny, but still able to hold their own. Saya can chop chiropterans in half with ease, and Diva was able to actually throw Saya clean through a ''brick wall'' without even trying.
* MyGodWhatHaveIDone: Van towards the end of the series after witnessing Delta 67 turn [[spoiler:many members of the public]] into Chiropterans.
* MysteriousProtector: Hagi, early in the series. Less so once TheWorfEffect kicks in.
* NakedOnArrival: How the Chiropteran queens emerge from their hibernation cocoons.
* NiceJobBreakingItHero: [[spoiler: Saya]] is responsible for unleashing Diva on the world. In her defense, however, she had no way of knowing what would happen, and it was more the original Joel and Amshel's fault that Diva became that way anyway.
* NighInvulnerability: Queens and their Chevaliers are capable of [[HealingFactor quickly healing almost any wound]]. This includes being impaled through the stomach with a tree trunk, stabbed with many large sharp implements and having arms cut off. If bad turns to worse and they are poisoned by Saya's [[BloodyMurder blood]], Chevaliers have the option to amputate themselves and obtain replacement limbs.
* NoCelebritiesWereHarmed: Two American politicians are based on Donald Rumsfeld and Condoleeza Rice; also note the hidden references to the Rothschild family in the names of the Chevalier. And "David" looks [[http://images.google.com/imgres?imgurl=http://www.pureanimegallery.com/d/1508-2/david-from-blood-plus.jpg&imgrefurl=http://www.pureanimegallery.com/v/bloodplus/david/david-2.jpg.html&usg=__6-Gr3AOmdy6-AYUQESoycNUAtvg=&h=150&w=200&sz=8&hl=en&start=1&tbnid=QH0MgfaQTon15M:&tbnh=78&tbnw=104&prev=/images%3Fq%3DBlood%2BPlus%2BDavid%26gbv%3D2%26ndsp%3D18%26hl%3Den%26safe%3Doff%26sa%3DN just a bit familiar]], especially to fans of [[DavidBowie another David]].
* NoOneCouldSurviveThat: [[spoiler: Hagi]] and the bombing of the opera house.
* NoSocialSkills: The Schiff due to being created to be used as living weapons. The very concept of asking somebody for something instead of taking it by force was completely alien to them.
* NotBloodRelated: Kai has a definite ''thing'' for Saya.
* Novelization: The Light Novel series by Ryo Ikehata, also acts as an AdaptationExpansion.
* NukeEm[=/=]ItsTheOnlyWayToBeSure: [[NuclearWeaponsTaboo though actual nukes aren't used]], the US military's primary method of dealing with Chiropterans is "Option D", aka "turn the place into a smoking crater".
* TheOnlyOneAllowedToDefeatYou: Saya considers it her personal duty to kill Diva, not merely because she's the best suited for the job, but also because [[spoiler: she was the one who released Diva in the first place.]]
* ObfuscatingStupidity [[spoiler: Nathan. Hinted at, and fully revealed in the end.]]
* OneWingedAngel: [[TheDragon Amshel]] and other Chevaliers. Strangely, [[BigBad Diva]] does not go through with this.
* TheOphelia: Diva really has the whole package going for her. Long hair, prone to sing songy babbling, broken princess.
* OurVampiresAreDifferent: Definitely one of the better uses of this trope and one that shows some real creativity. It's really a complete reinvention of the vampire archetype; they are a completely different species (rather than merely former humans[[note]]Ok, the Chevaliers are, but they can't exist without the queens.[[/note]]), with a [[BeePeople hive-like]] social hierarchy and reproductive method.
** It's worth noting that the Schiff, artificial chiropterans developed in a laboratory, are about as close as this series gets to traditional vampires. They look human, have superhuman strength and speed, need blood to survive, and burst into flames if they're exposed to direct sunlight for more than a few seconds.
* OutWithABang: [[spoiler: Riku.]]
* OverdrawnAtTheBloodBank
* PainfulTransformation: As seen when Saya turns [[spoiler:Riku]] to save his life, the conversion from human to chevalier is not a pleasant experience.
* PeopleJars: [[spoiler: How they make the Corpse Corps.]]
* PerpetualMotionMonster: Chirpoterans. One specifically had been sealed in a vault for decades with no blood and remained alive, yet emaciated.
* PinnedDown: Red Shield agents will provide support fire to keep enemy Chiropterans in one place distracting them from Saya.
* PlayingWithSyringes: The experiments with Delta-series drugs.
* PowerDegeneration: The Thorn for the Schiff, which slowly crystallizes their bodies. Saya goes through this when she [[spoiler: approaches her hibernation cycle]], suffering fainting spells and a weakened healing factor. [[spoiler:And Nathan reveals that Diva also suffered this as a result of her pregnancy, hence why her blood didn't petrify Saya when the two stabbed each other at the end of their FinalBattle.]]
* PowerPerversionPotential: [[spoiler: Rasputin]] used his [[FaceStealer shapeshifting]] abilities to get some naked gropes in on Saya while he looked like a girl.
* PrehensileHair: [[spoiler: Rasputin's]] primary method of attack in his Chiropteran form.
* ThePromise: Hagi's promise to Saya that [[spoiler:he will kill her after she defeats Diva]]
* PsychopathicManchild: Diva
* PsychoRangers: [[spoiler:The Corpse Corps are this for the Schiff. Despite undergoing similar treatment and brutal training, those of the Corpse Corps are emotionless, thoughtless, cold-blooded killers who will stop at nothing to achieve their goals as given by their masters. It's no wonder Moses freaks out when he sees who are really behind the masks.]]
* PsychoSerum: The Delta-series drugs originated as an attempt to create artificial Chevaliers to serve as {{super soldier}}s.
* PullingThemselvesTogether: Chevaliers border on this trope. Solomon and Hagi have been able to reattach their severed arms and use them just fine.
* TheQuietOne: Hagi.
* RapeDiscretionShot: When [[spoiler:Diva rapes Riku]].
* RavenHairIvorySkin: Both Saya and Diva, though the latter fits the trope better.
* RRatedOpening: The first episode begins with a {{flashback}} of Saya temporarily becoming AxCrazy and going on a killing spree through a Vietnamese village.
** MoodDissonance: This is immediately followed by the first TitleSequence with its bouncy J-pop theme music, then a present day scene with an unaged, perfectly sane Saya as an OrdinaryHighSchoolStudent.
* ReallySevenHundredYearsOld: Saya, Diva and their Chevaliers.
** Charles is noteworthy, since he is physically 12 years old.
* RevolversAreJustBetter: [[BadassNormal David]]'s WeaponOfChoice
* RoaringRampageOfRevenge: Diva's first action when Saya let her out was to kill [[spoiler: Joel and his staff]]. Things probably wouldn't have been so bad if she didn't extend it to all of humanity.
** Saya after [[spoiler: Riku's]] death.
* RomanticTwoGirlFriendship: Saya and Kaori act more like lovers than friends.
* RedEyesTakeWarning: Saya's eyes are a dull shade of red, but turn bright, glowing red when she uses her vampiric abilities. [[spoiler:Diva, the main antagonist, has blue eyes which also glow brightly when she's serious.]]
* RedOniBlueOni: [[spoiler: Saya and Diva, highlighted by their [[ColorCodedForYourConvenience Color Coded]] eyes, as mentioned above.]]
** George and David's OddFriendship [[spoiler: back when he was alive.]]
** There's also Kai to Riku and Saya. Really, the whole series is rife with this trope.
* RedRightHand: Subverted; Hagi's right hand gives away his true nature as a Chevalier, and freaks Saya out when she first sees it, but he is still a heroic character.
** Played straight with Karl's hand, which was injured when he fought Saya in the Vietnam war.
* ReluctantWarrior: Saya in the first half of the show.
* TheRenfield: Diva's Chevaliers, although they are a bit of a subversion.
* {{Roofhopping}}
* SaltAndPepper: David and Lewis.
* ScarfOfAsskicking: Saya sports one of these [[spoiler:during her final confrontation with Diva.]]
* SecretProjectRefugeeFamily: The Schiff.
* SecurityCling: [[spoiler: Moses and Carmen]] when they choose to burn up in the sun instead of succumbing to Thorn.
* SenselessViolins: Averted; Hagi keeps Saya's sword in his cello case, along with an actual cello, and plays it more than once. He's very good, too.
* ShapeshifterWeapon: Solomon's hand/blade.
* ShockAndAwe: One of Amshel's Chiropteran powers.
* ShutUpHannibal: Saya and Hagi's response to Amshel trying to give her a BreakingSpeech and TomatoSurprise. They [[CurbStompBattle failed]].
* SinisterScythe: Moses
* TheSleepless: Chevalier don't need to sleep. Saya has occasionally wondered how Hagi spends his sleepless nights.
* SlipknotPonytail: Hagi whenever he's taking a beating.
* SoldierVsWarrior: James and Saya.
* SparedByTheAdaptation: George, Riku, and Solomon in the manga.
* SpellMyNameWithAnS: Is it Haji or Hagi? No one seems to know for sure. Same goes for the Schiff/Sif.
** And Karl or Carl.
* SpoiledBrat: Saya (initially) thanks to Joel's superficial attempts at parenting. Meeting Hagi got her to mellow out.
* SpoilerOpening: If you pay attention to the background before the chorus starts in the first opening, you'll see a significant plot point for the last 13 episodes of the series.
* StealthPun: A feature found on some swords is commonly known as a "[[http://en.wikipedia.org/wiki/Blood_groove blood groove]]", but rarely so literally as in this series.
* StuffBlowingUp: The preferred method of dealing with accidents is 'Option D', which means dropping missiles on the affected area. On a smaller scale, Kai uses [[AbnormalAmmo special bullets]] which ultimately cause parts of [[NighInvulnerable Chiropterans]] to explode.
* SuperEmpowering: Drinking a Queen's blood will turn somebody into a Chevalier.
* SuperSoldier: The Delta-series and the Schiff were failed experiments in creating artificial Chevaliers to serve as super soldiers. [[spoiler:Ultimately, they succeeded with the Corpse Corps.]]
* StalkerWithACrush: Solomon and Karl both have this for Saya, although to different degrees. Solomon wants Saya to love him, while Karl wants to kill her while she kills him. [[spoiler: Diva had also developed this kind of obsession with Riku after she met him.]]
** This was also Mao's initial reason for following Kai across the world.
* StationaryWings: Occurs every now and then
* TheReasonYouSuckSpeech: Given by Kai to David after his [[HeroicBSOD BSOD]] as a part of [[GetAHoldOfYourselfMan snapping him out of it]]
* TheStoic: Hagi and David, but especially Hagi.
* SuicideBySunlight
* SunglassesAtNight: Lewis
* SwordDrag: Saya
* SwordPlant: Saya, again.
* TagalongKid: David sees Kai and Riku as this. Riku [[spoiler: [[OutWithABang is raped and killed]] by Diva]]. Post-timeskip, Kai [[TookALevelInBadass takes a level in badass]], becomes more mature and becomes an important asset to the team.
* TakenForGranite: Any Chiropteran killed by the blood of the opposing queen, as well as Schiff who die of the Thorn.
* TakingYouWithMe: In their final battle, Karl attempts to completely drain Saya of her blood, which would kill him as well, in the hopes that they would die together. Saya [[DeliberateInjuryGambit doesn't go for it]]. Ditto with James and later Amshel.
* TheTeam: Red Shield becomes this notably in the later half of the series.
** TheLeader/ BigGood: Joel Goldschmidt IV, the descendant of the founding family of Red Shield.
** TheHero: Saya, the only one who can kill Chiropterans, the Cinqe Fleches Chivaliers, and Diva.
** [[TheLancer The Lancers]]: Haji, being Saya's only Chivalier, and David, having a serious tone over his work.
** TheSmartGuy: Akihiro, the reporter who gathers information pertaining to Chiropterains.
** [[TheBigGuy The Big Guy(s)]]: Lewis, carrying most of hte heavy weapons. [[spoiler:Also the Schiff, who have the most experience in the war against Chiropterains and the only one who can kill them besides Saya and Haji.]]
** [[TheChick The Chicks]]: Kai, Julia, and Mao. They all give emotional support to various members of the team.
* TeamChef: Lewis does love to cook.
%% TearJerker was moved to the YMMV tab. Please don't add it back here.
* ThoseTwoGuys: Kakimoto and Kato, Kai and Mao's friends back in Okinawa. Their relevancy to the overall plot is about the same as air.
* ThickerThanWater: Subverted. One may expect [[ReluctantWarrior Saya]] to abandon her [[spoiler: adopted brothers]] after discovering [[spoiler: she's a Chiropteran]] and live with them. Instead, she decides to stay and fight as she feels the former are more important to her.
* ThroughHisStomach: David has a fondness for the horribly bitter coffee Julia brews.
* TimeSkip: An entire year passes between episode 32 and 33.
* TomatoInTheMirror: Thanks to her LaserGuidedAmnesia, Saya is initially unaware that she [[spoiler: is herself a Chiropteran]].
* TookALevelInBadass: Kai after [[spoiler: Riku's death]]
** Riku in the manga after the time skip, especially after learning of [[spoiler:Charles' death]], and Saya's plans for Diva.
* TragicKeepsake: Kai wielding George's handgun, Joel's dysfunctional watch, Saya's sword [[spoiler: when it becomes reforged with a crystal from her adopted father]], and Kai's necklace [[spoiler: which contains a crystal from Riku.]]
* TrueCompanions: The members of Red Shield, especially later in the series.
** The Schiff as well.
* {{Tsundere}}: Mao.
* VariableTerminalVelocity
* VegetarianVampire: Saya is one of a sort. She largely refrains from drinking ''any'' kind of blood, instead getting it through regular transfusions.
* UsefulNotes/TheVietnamWar: Part of the BackStory.
* ThreeMonthOldNewborn: The newborn Saya and Diva are described in Joel's diary as looking like two-month-old human babies. [[spoiler:Diva's daughters]] are a better example; from the minute they emerge from the cocoons, they have full heads of hair, and are cooing, smiling, and even giggling. Justified, since in both examples, the babies aren't human.
* ViolenceIsTheOnlyOption: Subverted. When Kai brings Irene back with him to just ask Saya if the Schiff can have some of her blood, Saya's response is to attack Irene. Kai and David talk her out of it and she agrees to give her blood to help Irene. And then the rest of the Schiff show up and think Irene has been captured and they start fighting again. This time it is Irene who talks them down.
* WalkingTheEarth: All the major characters do a lot of traveling.
* WeakButSkilled: Since Saya and Hagi get their blood from transfusions instead of eating humans like Diva and her Chevaliers, they aren't as physically powerful. They can still go toe to toe with them thanks to martial skills and teamwork.
** UnskilledButStrong: Diva contrasts this. She's nowhere near as skilled as Saya, but she's so strong and fast that she doesn't really need them.
* WeaponOfChoice: Each of the Schiff uses a different kind of weapon, many of them [[{{BFS}} fairly oversized]]. Saya wields a [[KatanasAreJustBetter specially designed katana]] [[spoiler: later reforged with a crystal from George]], David uses a [[RevolversAreJustBetter revolver]], Kai wields [[TragicKeepsake his father's handgun]] with [[AbnormalAmmo explosive ammo]], [[ManOfWealthAndTaste Solomon]] chooses to transform his hand into a [[SimpleYetAwesome simple and functional]] [[BladeBelowTheShoulder blade]]..... the list goes on. The weapons represent either their personalities or their history and emotions. Or both.
* WeAreTeamCannonFodder: Red Shield agents. The name is even a nod to this, their blood and flesh will become a shield for Saya so she can slay the Chiropterans.
* WillfullyWeak: [[spoiler: Hagi chooses not to use his higher end Chevalier powers because his initial usage terrified Saya. His [[RedRightHand right hand]] being [[ShapeShifterModeLock stuck in claw form]] is a source of shame for him.]]
* WingPull: [[spoiler: Hagi, when Saya falls off a skyscraper]]
* WhatHaveIBecome: [[spoiler:Saya's reaction to discovering she's a Chiropteran.]]
* WhatMeasureIsANonHuman: The Red Shield has little qualms about killing any and all chiropterans who ''aren't'' working with or for them (i.e. Saya and Haji), and neither do Saya and Haji. It's shown on multiple occasions that many chiropterans are capable of human emotions and have some form of conscience, but they don't seem to care: if they're out harming humans, they ''have'' to die. In the manga, Saya even explicitly tells Riku, her own brother, after his conversion that she's going to kill him simply for being a chiropteran.
* TheWorfEffect: Poor Hagi.
* WreckedWeapon: Amshel broke Saya's sword in their initial confrontation. When she got it reforged, David had a crystal that came from [[spoiler: George]] added to the hilt.
* {{Yakuza}}: Mao steals from her gangster father so she can follow the heroes around the world.
* YouAreWorthHell: Expressed by Solomon and Hagi towards Saya. Solomon threw away everything to try to be with her and Hagi doesn't regret his long life as a human pincushion either.
* YouShallNotPass: Hagi does his damnedest to perform one of these in episode 21, "Sour Grapes," against the Schiff. [[spoiler:And again, more successfully, in the finale.]]
