** Chistoph Gardos makes one to Asagi in episode 7 since she was the only one out of a hundred and fifty hackers to solve the puzzle they sent her. He then tells her that they need her help to be able to control the Nalakuvera super weapon. Right now, they only know how to activate it... which they do anyway. Now Asagi must decipher the ancient text and give this terrorist organization a means to control an unstoppable killing machine, otherwise it'll just run amok, possibly threatening the lives of everyone on the island.
** Vatler tells Kojou in episode 17 to bring Sana aboard his boat. While his intentions are certainly suspicious, he tells Kojou that he can come as well, and that the prison inmates that escaped will still likely try to kill her. So it would be best if they were away from the city to minimize collateral damage. Kojou accepts it, but Asagi forces him to take her as well.

----
!!''Strike the Blood'' provides examples of:
* AccidentalPervert: Kojou frequently ends up this, especially toward Yukina. Her typical reaction is what you would expect from a {{Tsundere}}.
* AggressiveSubmissive: Roughly half of the female {{Love Interest}}s are this. Yukina, Sayaka and Asagi are clear {{Tsundere}}-type love interests that antagonize Kojou and kick the ass of anyone who hurts their friends, but the ''moment'' Kojou takes aggressive sexual action, they pretty much lean back and let him do whatever he wants. Asagi, especially, seems to ''want'' Kojou to take her virginity forcefully. Kanon, La Folia, Yuuma are the exceptions, as they aren't very aggressive although clearly interested.
* AnOfferYouCantRefuse:
** Chistoph Gardos makes one to Asagi in episode 7 since she was the only one out of a hundred and fifty hackers to solve the puzzle they sent her. He then tells her that they need her help to be able to control the Nalakuvera super weapon. Right now, they only know how to activate it... which they do anyway. Now Asagi must decipher the ancient text and give this terrorist organization a means to control an unstoppable killing machine, otherwise it'll just run amok, possibly threatening the lives of everyone on the island.
** Vatler tells Kojou in episode 17 to bring Sana aboard his boat. While his intentions are certainly suspicious, he tells Kojou that he can come as well, and that the prison inmates that escaped will still likely try to kill her. So it would be best if they were away from the city to minimize collateral damage. Kojou accepts it, but Asagi forces him to take her as well.
* AntiMagic: Aya Tokoyogi casts a spell that negates all spells and superhuman abilities other than her own at the end of episode 18. Which is bad for Kojou as that means he can't use his healing powers either after he's stabbed by the former's familiar.
* AntiVillain: As mentionned by the protagonists [[StarterVillain Rudolf Eustach]] had a perfectly understandable and justified goal; [[WellIntentionedExtremist the problem was the extreme he was ready to go through to do it]].
** Kanase Kensei can also be seen as a [[SlidingScaleOfAntiVillains Type 3]]; [[spoiler: He genuinely believed that he could give Kanon happiness by letting her ascend to angelhood, and that she at the same time could prove a powerful force against a future threat.]]
* ArcWords: "That's enough for me." Spoken to Kojou on occasion by a girl whom he has just complimented or otherwise said something to bolster her esteem.
* BabiesEverAfter:
** Several of the women aboard Vatler's ship in episode 18 suggest this with Kojou. He immediately declines.
** In episode 23, [[spoiler:a time-traveling girl strongly resembling Yukina but with Kojou's eyes shows up. She also says some rather unusual things, such as calling Nagisa "aunt", and wonders if Yukina's nagging started at this point in time. She also demonstrates that she can quickly recover from injuries that would've been fatal for humans, and can summon a spear that looks like a golden version of Yukina's, and only stops short of saying she's their daughter due to Natsuki's interruption.]]
* BadassAdorable: All of the female cast are adorable, but this is especially the case for Astarte, Yume, Glenda and [[spoiler:Nagisa]], who are the youngest of the bunch. Played with in the case of Natsuki, as she is actually an adult, who only ''appears'' to be a cute young girl.
* BalancedHarem: The main heroine Yukina is [[TopWife at the top]], but Asagi, Sayaka and La Folia have decent development and screentime; Asagi barely edges out the lead amongst the three of them, with La Folia being next in line despite following Sayaka in appearance. Since Kojou needs several blood donors to summon and control familiars, all the girls get intimate moments with Kojou. Also, it's standard for a Progenitor to have a VampiresHarem [[spoiler:and indeed, time travel confirms Kojou will have a kid with more than one girl in the harem]].
* BareYourMidriff: Yukina's cheerleader outfit in episode 5.
* BedmateReveal:
** During ''The Labyrinth of the Blue Witch'' arc, a naked Sayaka wakes up to find herself sharing a bed with a naked La Folia. HilarityEnsues.
--> ''"Good morning, Sayaka. [[DoesThisRemindYouOfAnything You were wonderful last night...]]"''
** Asagi does this to Kojou in episode 6. When he wakes up, she's leaning on top of him. He responds by trying to fall back asleep, then asks her what she's plotting.
* BigBad: The overall villain of the entire story, whom the Fourth Progenitor has been created by [[spoiler: the Tengu]] to defeat is [[spoiler: Cain, the Father of Demons]].
* BigDamnHeroes:
** Kojou saves Yukina in episode 2 when Astarte begins to gain the upper hand against her.
** Kojou and Yukina do this to save Kanon in episode 12.
** Astarte saves Asagi and Sana from Kiliga in episode 17.
** Vatler does this for the two after Gigliora shows up and attempts to take out Astarte. However, whether it's this trope or VillainousRescue is debatable, since Vatler was mostly doing it because he wanted [[ItAmusedMe to see some action]], rather than out of the kindness of his heart.
* BigNo: Yukina lets one out at the end of episode 3, [[spoiler:after Kojou intercepts an axe-blow from Eustach, and gets decapitated for his efforts.]]
* BladeOnAStick: Himeragi's retractable weapon, Seikarou.
* BloodKnight: Christoph Gardos loves the thrill of war so much that he is trying to cause a war just for this reason.
* BloodSplatteredInnocents: Kojou's blood splatters on half of Yukina's face in episode 3 after he [[TakingTheBullet intercepts]] Eustach's axe attack intended for her.
* BreatherEpisode:
** Episode 5. While there is some action, it's not nearly as intense as in the previous two, and there are some lighthearted comedy scenes at school.
** Episode 9 starts off with some wacky high school hijinks, following yet another intense battle from the previous episode.
* CallingYourAttacks: Par for the course of any action series.
* CensorSteam: Used in episode 18 when Kojou is taking a bath aboard Vatler's ship, along with Asagi and Sana.
* ChildSoldier: Lion King's members like Yukina are all orphans who have been recruited from young age and formed to serve as weapons.
* ClingyJealousGirl: Yukina gets this the most. Asagi and Sayaka also have their moments.
* ConservationOfNinjutsu:
** When Kojou first faces off against a Nalakuvera, he has some difficulty with it. But once Christoph Gardos hops into the queen one, along with controlling several others, the heroes don't have much difficulty defeating them.
** The various prison inmates that escape in "Fiesta of the Observers" arc are certainly a threat, but as a whole, they're defeated rather easily compared to when it's just one villain attacking.
*** Interestingly, Aya Tokoyogi, the VillainOfTheWeek, makes short work of both Kojou and Sayaka, and kidnaps both Sana and Yukina at the end of episode 18.
* ContrivedCoincidence: In episode 17, Kojou, Sayaka, and Yukina discuss figuring out where Natsuki went. They then see Asagi on the television watching the Halloween Festa parade, and she just happens to be holding the hands of a little girl who strongly resembles Natsuki.
* CostumePorn: The animators love giving Yukina a change of clothes, sometimes several per episode. No other character in the series gets as many costume changes. In addition to her School Uniform(s), she's been shown dressed in: underwear, cheerleader uniform, party dress, yukata, birthday suit, Kojou's hoodie, maid costume, nurse outfit and gym uniform. Cop, cowboy, construction worker and Indian chief are probably left for the next season.
* CrouchingMoronHiddenBadass: Kojou isn't exactly stupid, but he is rather laid-back, lazy and generally lacking any drive or motivation in his daily life; definitely not what you would expect from one of the most powerful vampires in the setting.
* CurbStompBattle: Happens on several occasions.
** Typically Kojou and Yukina will be on the receiving end of one, but shortly afterwards the situation changes in their favor, and they end up dishing one out to the VillainOfTheWeek.
** At the beginning of episode 16, Vatler is taken out by a tiny girl, [[spoiler:Avrora using Nagisa's body]]. She gives him a warning and then leaves.
** Astarte takes out Kiliga rather easily once she shows up in episode 17.
* CuteBruiser: Yukina; see BadassAdorable further up.
* CutenessProximity: Yukina when she sees the stray cats Kanon and Nagisa were attempting to find homes for.
* DamselInDistress: Yukina suffers from this in episode 19.
* DeusSexMachina: Toned down; Kojou's BloodLust apparently activates through sexual arousal, meaning he needs to be aroused to suck blood and can lose control whenever it happens. However, it usually just takes fairly modest fanservice (such as panty or skin exposure from a girl) to get a reaction from him, so no real sex has been involved so far.
* DidYouJustHaveSex:
** When both Kojou and Asagi show up at school complaining about not getting enough sleep, Orin teases them about the possible reason.
** In Episode 21, [[spoiler:Asagi]] wakes up in Kojou's bed half-naked and starts to cry when she ponders what might have happened. [[ArentYouGoingToRavishMe She's disappointed when Kojou tells her the truth.]]
** As per usual, played with due to KissOfTheVampire:
*** Whenever Kojou shows up with a new familiar, [[ClingyJealousGirl Yukina is quick to question how he got it.]]
*** In Episode 19, Sayaka shows up to the final battle with her blouse buttoned wrong, which Yukina bitterly points out to her.
** A very straightforward example the OVA, where the BigBad villainess places Kojou under her control with {{Pheromones}} and later takes Yukina and La Folia hostage. She forces the mind-controlled Kojou to dote on her, and then notices that doing so is making Yukina jealous. Just as a TakeThat, she then orders Kojou to BridalCarry her into the bedroom. We never see what happened afterwards, and not knowing greatly bothers Yukina.
* DisproportionateRetribution:
** Stated to be this, in-universe. Kojou has to stop Himeragi from brutalizing some guys after they flipped her skirt. However, it's worth noting that she politely asked them to leave her alone and attempted to step past them several times. She only struck out at them after they ''grabbed'' her and pretty much yelled out "Where are you going, [[ThisIsForEmphasisBitch bitch]]?" Out-of-universe, no woman in her right mind would consider this "disproportionate".
** Played straight anytime Yukina hits Kojou for any acts of perversion, real or perceived. Even if it was entirely accidental.
* DistractedByTheSexy: Kojou gets hit with this from time to time, such as in episode 21 when Nina asks for his help while inside Asagi's nearly naked body. He agrees but [[PleasePutSomeClothesOn asks her to put on some clothing.]]
* DoesNotLikeMen: Kirasaka, to the point [[HatesBeingTouched she can't even stand their contact]].
* DoesThisRemindYouOfAnything:
** Vampires who have never fed on human blood are referred as "virgins".
** During KissOfTheVampire scenes, the girls say things like, "Not there, it hurts" or "Not so rough".
** When Kojou is ready to feed on [[spoiler:Sayaka]] the second time, she nervously says, "I'm not ready! I haven't even showered yet...!"
** [[spoiler: At the climax of the Empire of the Dawn arc, Kojou is feeding especially... energetically from Yukina, and her reaction is equally... energetic. Everyone present for this is looking around awkwardly, as if witnessing a couple passionately making out.]]
** See ThatCameOutWrong, below.
* DudeWheresMyRespect: Despite the fact that Kojou is an immortal monster who can literally wipe an entire city off the map with incredible ease, a surprising number of people seem to think it's a good idea to fight him. Justified in that he's still coming into his power, and that he's only able to win most of his fights with help due to inexperience.
* ElegantGothicLolita: Natsuki
* EnemyMine: Asagi and Sayaka are forced to work together to locate and rescue Kojou and Yukina in episode 10. Both of them are distrustful of the other, due to their relations and connections with him.
* EroticEating: Mimori Akatsuki eating a popsicle rather suggestively in episode 16.
* FakeFirstKiss: Yukina has her first kiss with Kojou because Kojou is a vampire whose powers only activate with sexual arousal (although Yukina [[{{Tsundere}} also in love with him, but denies it]]). During the incident in question, the two of them are trapped underneath layers of ice and facing certain death along with the astonishingly-beautiful [[PrincessClassic La Folia]]. La Folia (who is [[ChickMagnet also hot for Kojou]] tries to kiss him to get Kojou's power to awaken, but [[ClingyJealousgirl Yukina stops her and does it in her stead]].
* FalseFlagOperation: The "Free Terrorists" movement in the OVA tried to use one of [[spoiler: Aldegyr's]] battleship to crash the peace conference between [[spoiler: Aldegyr and Warlord's Dominion]]. Based on La Folia's words, seems like the terrorist group was secretly backed up by [[spoiler: North Sea Empire.]]
* {{Fanservice}}: Used on occasion throughout the show. The camera will sometimes [[MaleGaze pan and scan]] the particular female during that scene.
* FantasticRacism: The various supernatural races... don't get along. Because of their sheer age and power most Vampires look down both on humans and a subset of Vampires called Nosferatu who can't materialise Beast Vassals. There are also mentions of both Beast-men and Human Supremacist groups.
* FirstGirlWins: Asagi and Yukina are the first two female characters shown having significant interaction with Kojou. Come ''Strike the Blood EX,'' it's confirmed that [[spoiler: he's married to both of them.]]
* ForegoneConclusion: The "Empire Of The Dawn" arc reveals that [[spoiler: Kojou and Yukina ''will'' indeed get married and have a child. Moreover it also establishes that during the next 20 years Itogami Island will become a sovereign nation under Kojou's rule. TheStinger also reveals that Yukina is not the only woman to bear his child.]]
* {{Foreshadowing}}: At the start of the ''Labyrinth of the Blue Witch'' arc, Natsuki is seen dressing in the middle school girl's uniform, in order to catch a groper on the monorail. At the end of the arc [[spoiler: Natsuki is transformed into a little girl ''for real'' by a spell from the Witch of the Notaria.]]
* FreakyFridayFlip: Happens to Yuuma and Kojou in episode 13.
* FriendlyNeighborhoodVampire: Despite being a PersonOfMassDestruction and one of the most powerful vampires in the world, Kojou is in no way evil, and satisfies his BloodLust by drinking his own blood. In fact, when he became the Fourth Progenitor, his first idea of how to use his powers was to try to make the world a better place by focusing on {{Asshole Victim}}s, but he gave up on it and settled on trying to keep a normal life.
* GeckoEnding: The "Empire of the Dawn" arc is exclusive to the anime and makes up its ending. While it shows a glimpse of [[spoiler: [[DistantFinale the far future]]]] [[StatusQuoIsGod the status quo is ultimately maintained]], allowing for a possible second season to pick up where the anime left off.
* TheGlomp: Sayaka does this to Yukina in episode 6, while simultaneously pushing Kojou away from her.
* GodivaHair: Asagi in episode 21.
* GRatedSex: One of the recurring gimmicks of the show. [[KissOfTheVampire Vampire bites carry the same implications as sex]]. For example, a person who provides blood to a vampire becomes "blood-bonded", and being bitten on "unsafe days" can cause one to become a vampire. Possibly because of these facts, Kojou never bites or drains the blood of any person who doesn't want it--even an enemy. Furthermore, the interactions between Kojou and his "blood partners" during the bloodsucking invokes sexual imagery and eroticism. Other people who observe it also react the same way most would when watching a couple having sex.
* GoryDiscretionShot: Averted for the most part.
** [[spoiler:In episode 3, Yukina can be seen gripping Kojou's head when it detaches from his body after taking Eustach's axe attack.]]
** Eustach slices a demon in episode 2, with his chest wound visibly shown onscreen. In episode 4, he walks by the bodies of guards after Astarte dispatches them.
* GrandTheftMe: Koujou gets his body stolen by [[spoiler: Yuuma when she kisses him. This also leave Koujou stuck in a [[GenderBender girl's body.]]]]
* GratuitousItalian: Kojou does this in episode 1 to fool Yukina into thinking he's someone else.
* HamToHamCombat: Asagi and Sayaka do this in episode 10.
* HaremSeeker: Both a DiscussedTrope and InvokedTrope. Apparently, due to their immense power, charisma, and status, Progenitors are ''supposed'' to be this. The central axis of the plot is the appearance of a random Progenitor (Kojou) in Japan, which makes everyone around nervous about what he's going to do. Kojou himself wants no part of it, but everyone else around him from the Lion King Organization, to his own Familiars, to other vampires, continue to force this onto him. It's especially telling when there's a familiar that requires the blood of ''two'' people to work. [[spoiler: he forcibly marries (without consent) the first 10 girls the 11th girl (who he gets his kenjuu and the last girl, he makes an AguishedDeclarationofLove to and Yukina's insecurities about her current conditions make her reject him.]]
* HateAtFirstSight:
** Sayaka and Asagi. When they first meet, the former was beating up Kojou, who was suspicious of what he was doing with the latter. When they see each other again in episode 10, they immediately get into an argument again regarding Kojou. Poor Yaze is forced to be the peacekeeper as a result.
** Nagisa isn't too fond of Sayaka either for similar reasons. So when they see each other in episode 17, she immediately questions the latter's relationship with her brother. Kojou uses this opportunity to get Nagisa away, and pushes Sayaka towards Nagisa, who promptly leads her out of the room for further questioning on said relationship.
* HatesBeingTouched: Kirasaka, though only by men. [[spoiler:She appears to be able to make an exception with Kojou eventually.]]
* HeroStoleMyBike: In episode 17, Yukina slashes the chain off a bike at a convenience store after the half-track they were using runs out of gas. She says they'll apologize to the owner later on.
* HotterAndSexier: The OVA and Season II are both much less heavily censored than the first season.
* IdiotBall: Episode 20, [[spoiler: Kojou urges Asagi to leave the monastery right away but she wastes time complaining how she needs to find the earring she lost. When Kojou tells her he'll buy her replacement earrings, she wastes even more time asking what kind he'll buy.]]
* IgnoreTheFanservice: For someone so frequently accused of being a pervert, Kojou is hilariously indifferent and oblivious when Asagi ''actually'' tries to seduce him.
* IKnowYoureInThereSomewhereFight: Kojou does this for Kanon to help bring her back when she nearly lost the remnant of her humanity.
* ImpaledWithExtremePrejudice: Happens twice in episode 15:
** The first time is with Yukina stabbing Yuuma while the latter is possessing Kojou's body.
** The second time happens as TheStinger, [[spoiler:when Yuuma and Natsuki both get stabbed by Yuuma's guardian, who's being controlled by her mother.]]
** Kojou suffers one in episode 18 by Aya's familiar.
* InsecureLoveInterest: Almost every girl in the show fits this, especially when comparing themselves to one-another. Several times, when Kojou attempts to refuse drinking her blood, a girl will say something like, "Do you not find me attractive?"/"Am I not as pretty as [other girl]?", guilting Kojou into feeding on her.
* InTheHood: Kojou's favourite way to dress.
* InsistentTerminology: Natsuki ''hates'' it when the affectionate suffix of "-chan" (IE. "My cute little Natsuki") is added to her name. As she [[CatchPhrase often has to say]]...
--> It's Natsuki-sensei.
* IntimateHealing: Yuuma licks Kojou's finger after he cuts it from picking up the broken glass cup he dropped in episode 13.
* KissOfTheVampire: Played with; although still undeniably erotic as per usual with this trope, instead of an invasive rape-metaphor, the scenes in the Anime where Kojou partakes in the blood of his love interests are portrayed as surprisingly tender and heartwarming moments of sincere bond, trust and friendship. The gentle and romantic piano music used in said scenes really helps.
* LensFlareCensor: Used in the broadcast version of Episode 11 to cover Yukina and La Folia's lower halves.
* LittleSisterHeroine: There have been small hints that Nagisa harbors romantic feelings for Kojou. At one point, she laments that she's too old to bathe with him and, more strongly, she makes sexual advances towards him while under [[spoiler:Yume's influence--and Yume later ssays that her powers only enhance someone's deepest desires.]] For his own part, Kojou's overprotectiveness of/devotion to Nagisa often gets him accused of having a sister complex, particularly in the light novels.
* LoopholeAbuse: Yuuma uses this in episode 19 to help Kojou regain his powers, [[spoiler:since Aya Tokoyogi's powers weren't affected by the AntiMagic spell. And since Yuuma is a clone of hers, it won't affect her powers either...]]
* LoveLetterLunacy: Invoked a couple of times:
** The first is in episode 5, when Asagi catches Kojou holding a letter with Yukina showing off a LuminescentBlush. She immediately interprets it as this trope and runs off.
** In episode 9, Kojou and Yukina spot Nagisa talking to a boy and receiving what the latter thinks is a love letter. He doesn't take it too well when Yukina says that Nagisa is popular with the boys, and later on follows her to the school rooftop. They hear some rather suggestive sounding dialogue, then open the door, to find out they were [[spoiler:just talking about a cat.]]
* MaleGaze: Used occasionally throughout, such as when Kojou stares at Sayaka's chest in episode 8 after the latter has gotten wet.
* MakeMeWannaShout: Yaze's powers allow him to control sound.
* MarryThemAll: The final volume reveals [[spoiler: he's married to 12 girls.]]
* MistakenForGay: Asagi asks what may appear to be an ArmorPiercingQuestion regarding his status as a vampire, but instead she asks if he's into men, due to his apparent lack of interest in the various girls around him, along with being on somewhat too friendly terms with Vatler. Later, after he shakes the hand of one of Vatler's butlers, Asagi asks this again.
* MonsterSlayerRomance: Kojou is the Fourth Progenitor vampire and Yukina is a Sword Shaman sent to observe and potentially eliminate him should she deem him dangerous.
* NaughtyNurseOutfit: Yukina wears one in the "Fiesta For the Observers" arc. Mostly because Kojou's mother, Mimori, made her wear it to help to stabilize Yuuma after the latter was stabbed. While it's a fairly normal looking outfit, Kojou mentions that she looks really good in it.
* NiceJobFixingItVillain:
** Christoph Gardos forces Asagi to unlock the manual needed to activate and control the Nalakuvera. And he does it by giving her access to the latest supercomputer. Fortunately for the heroes, she puts her PlayfulHacker skills to good use, and installs a self-destruct program on the otherwise NighInvulnerable warmachines as well.
** In episode 19, Aya Tokoyogi creates a barrier that negates all superpowers and magical abilities on the island, except for her own. [[spoiler:Yuuma then exploits this to help Kojou recover, since she's a clone of Aya, so therefore her magical abilities aren't affected either.]]
* NinjaMaid: Astarte is made this by Natsuki after she is placed under her service.
* {{Nosebleed}}: Kojou has one whenever he gets sexually aroused. Interestingly, he takes ''advantage'' on it by drinking the resulting blood, such satisfying his own blood lust without having to harm anyone.
* NotWhatItLooksLike: Kojou is often in these sorts of situations, such as when he accidentally knocks Asagi off his bed in episode 6, and falls on top of her. Naturally Nagisa and Yukina both walk in at the same time, wondering what's taking her so long to wake him up.
* OffWithHisHead: [[spoiler: Kojou at one point gets his head brutally hacked off while attempting to save Himeragi. [[DisneyDeath He gets better]] [[GoodThingYouCanHeal quite fast]].]]
* OlderThanTheyLook: Natsuki looks like a grade schooler despite being 26.
* OhCrap: Yaze has this reaction in episode 10 shortly after he runs into Sayaka at the ruined church. He was trying to make a deal with her to find Kojou and Yukina, but then hears Asagi and Nagisa approaching, and isn't able to stop them from running into each other. A big HamToHamCombat ensues between Asagi and Sayaka after they meet.
* OneDialogueTwoConversations: In episode 8, Sayaka asks Kojou about [[DCupDistress "being big"]]. He says they are, but then mentions that some guys [[BuxomIsBetter like it big.]] She then clarifies that she was referring to her height.
* OneManArmy: According to Yukina, becoming the Fourth Progenitor made Kojou the equivalent of several armies put together.
* OurVampiresAreDifferent: [[DaywalkingVampire Sunlight]] doesn't affect them, they have Superpowered {{Familiar}}s inside of them, and apparently, they're immortal.
** Later volumes of the novels also introduce additional types. The first a "Ghouls" or "Nosferatu", less human looking Vampires who don't possess Beast Vassals but gain the ability to transform parts of their bodies into living weapons and a generally looked down on by regular vampires. There are also Blood Vassals, humans transformed into pseudo-vampires by grafting a regular vampires flesh into their body, similar to what Kojou did to Astarte but more permanent.
* OurWerebeastsAreDifferent[=/=]OurDemonsAreDifferent: Demons in this series (sometimes translated as Therianthrops) are portrayed as werebeasts.
* PeaceConference: In the OVA, it happened between [[spoiler: Aldegyr and Warlord's Dominion]]. [[spoiler: Good thing that it succeeded.]]
* PersonOfMassDestruction: Kojou, by virtue of being the Fourth Progenitor.
* PlayfulHacker: Asagi is a skilled computer expert.
* PoseOfSupplication: Yukina subjects Kojou to these a lot to reflect on his perverted acts. Especially if they were accidental and entirely out of his control.
* PrecociousCrush: Several of the girls crushing on Kojou are middle-school age. And two of the youngest are Astarte and Yume, who are grade-schoolers. Yume even asks Kojou to "wait" for her.
* {{Precursors}}: The Devas, an ancient race of superhumans who helped the original Three Progenitors create the Fourth Progenitor.
* PrimalFear: Nagisa goes into hysterics whenever an untransformed demon appears.
* RedEyesTakeWarning: Kojou's eyes ordinary are blue, but they turn red whenever he uses his vampiric abilities.
* ReiAyanamiExpy: Astarte, especially after her HeelFaceTurn.
* RomanceEnsues: A constant for this show, to the level of [[OnceAnEpisode Once An Arc]]. It only stops short of being CoitusEnsues due to KissOfTheVampire being used in place of actual sex.
** When Kojou and Yukina are defeated and try to figure out how to gain an advantage over the Combat Deacon, she suggests he take her blood and awaken a familiar.
** When Kojou and Sayaka are trapped in a chamber that will drown them in a matter of time, she suggests he take her blood and awaken a familiar.
** When Kojou, Yukina and La Folia are trapped in ice with murderous villains surrounding them on the outside, La Folia suggests that he take her blood and awaken a Familiar. [[SubvertedTrope Yukina stops her and offers herself in her stead]], but after she's asleep, [[DoubleSubversion La Folia is right back on it.]]
** When Kojou and Sayaka are alone after Kojou is mortally wounded by Aya, she suggests that he take her blood to heal. When she fails, Yuuma arrives and suggests the same thing using ''both'' their blood. [[ComboBreaker When Kojou doesn't heal, he realizes he needs to awaken a familiar.]]
* ScreamDiscretionShot: Typically used when Kojou is being punished for being a pervert, or rather [[UnprovokedPervertPayback Yukina thinks he's being one.]] Anything dealt in these situations is always PlayedForLaughs.
* SempaiKouhai: Yukina always addresses Kojou as senpai.
%%* ShesGotLegs: Yukina.
* SheIsNotMyGirlfriend: Kojou and Yukina repeatedly deny being a couple despite their obvious closeness and romantic attraction.
* ShockAndAwe: A fair bit of it, coupled with {{Yellow Lightning Blue Lightning}}. Kojou has his "Regulas Aurum" Familiar, a giant lion made of (yellow) lightning, whereas Yukina has two spells that enhance physical attacks with (blue) lightning. Her spear also generates what seems to be electricity when it pierces something as well.
** Subverted with Sayaka, then played straight: Her chant when using her magical arrows invokes a "god of thunder", but at first, only nullifies magic. Later, with the same incantation, she does indeed call down a barrage of (blue) lightning bolts.
* SingleWomanSeeksGoodMan:
** Yukina states that the reason her opinion changes about Kojou early on is because of his NiceGuy demeanor, and later says that his tendency to worry about others despite his own imminent danger is what she likes about him.
** La Folia's interest in Kojou piques when he shows concern over Kanase Kanon's endangerment. Specifically, at the exact time he makes it clear that he intends to save her before her mind breaks down completely, she literally throws herself at him. At several times, she asks that he prove she's "not wrong about [him]".
** Kanon first shows interest in Kojou after he pays her a compliment and helps her find homes for some kittens she'd been looking after. He later saves her life as well.
** Yuuma likes Kojou because his words and actions help her feel like a real person [[spoiler:rather than a tool programmed to do someone else's will]]. When he hits her with a KirkSummation at one point, she says that his ability to say the right thing so easily is what she's always liked about him.
** Yume falls for Kojou when he stops her from an elaborate suicide attempt due to the misery her succubus powers force upon her. He passionately proclaims that he will destroy anything that ever makes her unhappy ever again, which she chooses to interpret to mean "I will make you happy forever".
* SingleStrokeBattle: Yukina and Christoph Gardos in episode 8. She slices off his right arm, and declares the battle over. He agrees, but only because he still has Asagi and Nagisa hostage, as well as an army of Nalakuvera now.
* SkewedPriorities: It seems the girls in the show are usually more concerned with the other girls around Kojou, than the fact that there may be weird things happening, or a villain attacking the city.
** Sayaka gets into a HamToHamCombat debate with Asagi when they first run into each other in episode 10. Even after they locate where Kojou and Yukina are, they once again get into an argument about the other's relationship to him.
** When Kojou is first subjected to the random teleportation in episode 13, he unintentionally winds up in Yukina's bathroom where Astarte and Kanon are taking a bath. Yukina is much [[ClingyJealousGirl more obsessed]] that he saw the two girls naked, than the fact that he was afflicted with the same teleportation that Sayaka and La Folia went through.
** Nagisa gets extremely suspicious of Sayaka as well, wondering what her relationship with her brother is exactly. Never mind that Yuuma is dying on the couch in the room during that particular encounter. Possibly justified, though, in that the three times Nagisa has run into her, something bad has happened to one of Nagisa's friends, so she has good reason to demand answers.
* SortingAlgorithmOfEvil: The villains who attack throughout the show gradually threaten more and more of the city, and usually forces Kojou to obtain a new power to defeat them.
* SpitTake: Kojou does one in episode 21 after Asagi, who was taking a bath in his apartment, goes out of the bathroom while still naked.
* StealthHiBye: Several characters make use of this, showing up out of nowhere a lot of times. While it is utilized by the villains occasionally, it's more often played for comedic effect when Kojou says or does something around one girl, causing another girl to show up and put some ClingyJealousGirl retribution on him.
* TheStinger: At the end of episode 15, it seems all is well with Yuuma and Kojou. [[spoiler:Then her guardian [[ImpaledWithExtremePrejudice stabs]] her and Natsuki.]]
* SuspiciouslySpecificDenial: In episode 10, Yaze makes a deal with Sayaka. In exchange for her not telling Kojou and Yukina what his true identity is, he'd tell her where Kojou was. She blushes, looks away, and [[{{Tsundere}} vehemently denies]] wanting to hear anything about that. When he also mentions Yukina, she seems to change her tune, although Asagi and Nagisa approaching the ruined church interrupts the deal.
* TakenForGranite: Happens to the Nalakuvera in episode 8.
* TalkingIsAFreeAction:
** In episode 8, Yukina is explaining to Kojou and Sayaka about a new command Asagi threw into the Nalakuvera and how to destroy them. Christoph Gardos is polite enough to hold his forces back and not attack them while she's doing it.
** The Meyer witches also kindly wait for Sayaka and La Folia to finish their description of former's familiar, which is giving them a lot of problems. Once the two figure out how its nature, they exploit its weakness to defeat them.
* TeamworkSeduction: JustifiedTrope. Protagonist Kojou Akatsuki is a vampire whose powers only work if he drinks other peoples' blood, and vampiric bloodlust is akin to actual ''sexual'' lust, meaning he has to be turned on to drink blood. So this trope happens ''twice''.
** On one occasion, a familiar turns out to need ''two'' peoples' blood to work properly, so when one girl fails to do it alone, the other steps up to the plate as well.
** On the second occasion, this trope is fully invoked, both because a single girl can't arouse the dying Kojou enough to save his life, and because only one of them has blood immune to the AntiMagic field preventing his powers from awakening. So it takes one girl to restore his powers and the other to slake his thirst.
* TemptingFate: In episode 9, Valter asks Natsuki not to let Kojou get involved in the current situation, since he believes the latter wouldn't stand a chance against the new VillainOfTheWeek. Naturally, this assures that he will get involved.
* ThanksForTheMammaries:
** Kojou accidentally does this in episode 8 after Sayaka slips on some rubble and falls back on him.
** Mimori does this to Yuuma in episode 16. When Yukina inquires about it, the former says that fondling the breasts of cute girls is what activates her powers. Kojou immediately calls his mother out on this.
** Kojou trips again on Sayaka in episode 22, made even worse since he thought he was fondling the shikigami made by Yukina's master.
* ThatCameOutWrong: Sigh... What sweet and innocent little Yukina-chan ''tried'' to say to Kojou was "His ''bite'' didn't hurt too much, she didn't lose too much blood, it was a safe-day on the ''astrological'' cycle and hence the tests for her ''becoming a vampire'' came back negative. But [[SugarWiki/FunnyMoments paraphrased by Asagi who overheard the exchange]], it came out as:
--> '''Asagi''': "So you didn't hurt her too much, she lost a little blood, but it was a "safe day" so her [[TeenPregnancy "test"]] came back negative, huh?"
* TheCallKnowsWhereYouLive: Kojou honestly has no specific ambition or goal beyond "being left alone", but people keep coming in his life due to his status and end up bringing him into supernatural situations.
* ThoseTwoGuys: Invoked and PlayedForLaughs in episode 13. When Kojou is waiting for his childhood friend Yuuma to arrive, Asagi and Yaze show up uninvited as well. Yaze says that Kojou can just consider them "passers-by". So when Yuuma does show up, that's exactly how Kojou introduces them as.
* TopWife: In the OVA, La Folia is the first girl to propose to Kojou and claims to have no issues at all with Kojou's relationships with other women. However, when the subject of polygamy is raised, she brazenly offers Yukina the position of "second wife", though Yukina is without a doubt at the top of the food chain. This is later confirmed in Season 3, after accidentally Yukina becomes Kojou's "blood mate" after volunteering her blood one too many times. At that point, she becomes practically locked in as his number one spouse (although she and Asagi are still in competition) and La Folia seems to be satisfied with accepting a position as his concubine. Averted in the final volume as there is no heirarchy and kojou outright considers them his wives as hanryo aka companion is the female equivalent to wife in a vampires harem
* {{Troperiffic}}: Totally. An OrdinaryHighSchoolStudent blessed with the blood of the world's most powerful [[OurVampiresAreDifferent vampire]] teaming up with a [[BadassAdorable cute]] ActionGirl in order to fight powerful enemies threatening the fragile peace of their everyday lives, with a lot of action and magic tropes thrown in, as well as a few dashes of {{Fanservice}} and HaremGenre. Just looking at the character sheet's length is enough to give you a cue.
* VegetarianVampire: Kojou initially, in that he feeds on his own blood rather than drink others. It's the main reason why his familiars don't follow his orders.
* WhamEpisode:
** Episode 3 has a particularly brutal one. During their fight with VillainOfTheWeek Eustach, Yukina is on the receiving end of a CurbStompBattle. As Eustach raises his axe for a final blow against her, Kojou [[TakingTheBullet intercepts it]]. While it saves Yukina, [[spoiler:Kojou gets decapitated for his efforts.]]
** In episode 18, Kojou's familiar is banished, he's stabbed by Aya's familiar, and both Sana and Yukina are taken hostage.
** At the end of episode 20, [[spoiler:Asagi]] gets slashed from the front badly enough that Kojou thinks she's dead. However, [[spoiler: she survives due to the intervention of a new character, who heals Asagi ''and'' hijacks her body]].
* WhatDidIDoLastNight: The entire plot of the ''Missing Lance'' OVA. Turns out [[spoiler: it was caused by Kojou accidentally putting magic mushrooms in their hot pot. [[IntoxicationEnsues Intoxication]] and harem hijinks ensued]].
* WorstAid: Yuuma is stabbed with a massive sword [[spoiler: by her mother]]. Kojou and Yukina do not put pressure on the wound, or make any effort to stop the blood. When they take her to Kojou's mother for treatment, she delays the treatment further to catch up with Kojou, and [[DudeShesLikeInAComa fondle Yuuma's breasts]]. It's astonishing that the poor girl survives.

The Fourth Progenitor—That's the world's strongest vampire that should only exist in legends. Accompanied by twelve [[{{Familiar}} Familiars]] and spreading chaos and mayhem, this phantom vampire has now appeared in Japan. In order to deal with potential threat, the government and the Lion King decided to dispatch a Sword Shaman to keep an eye on him, and kill him if he becomes a threat. However, for some reason, the one chosen for the observation was an apprentice Sword Shaman girl, Himeragi Yukina. Wielding the strongest anti-progenitor spirit spear, Yukina arrived at Demon District, Itogami City. What will she find when she encounters the Fourth Progenitor, Akatsuki Kojou?!

----
!!''Strike the Blood'' provides examples of:
* AccidentalPervert: Kojou frequently ends up this, especially toward Yukina. Her typical reaction is what you would expect from a {{Tsundere}}.
* AggressiveSubmissive: Roughly half of the female {{Love Interest}}s are this. Yukina, Sayaka and Asagi are clear {{Tsundere}}-type love interests that antagonize Kojou and kick the ass of anyone who hurts their friends, but the ''moment'' Kojou takes aggressive sexual action, they pretty much lean back and let him do whatever he wants. Asagi, especially, seems to ''want'' Kojou to take her virginity forcefully. Kanon, La Folia, Yuuma are the exceptions, as they aren't very aggressive although clearly interested.
* AnOfferYouCantRefuse:
** Chistoph Gardos makes one to Asagi in episode 7 since she was the only one out of a hundred and fifty hackers to solve the puzzle they sent her. He then tells her that they need her help to be able to control the Nalakuvera super weapon. Right now, they only know how to activate it... which they do anyway. Now Asagi must decipher the ancient text and give this terrorist organization a means to control an unstoppable killing machine, otherwise it'll just run amok, possibly threatening the lives of everyone on the island.
** Vatler tells Kojou in episode 17 to bring Sana aboard his boat. While his intentions are certainly suspicious, he tells Kojou that he can come as well, and that the prison inmates that escaped will still likely try to kill her. So it would be best if they were away from the city to minimize collateral damage. Kojou accepts it, but Asagi forces him to take her as well.
* AntiMagic: Aya Tokoyogi casts a spell that negates all spells and superhuman abilities other than her own at the end of episode 18. Which is bad for Kojou as that means he can't use his healing powers either after he's stabbed by the former's familiar.
* AntiVillain: As mentionned by the protagonists [[StarterVillain Rudolf Eustach]] had a perfectly understandable and justified goal; [[WellIntentionedExtremist the problem was the extreme he was ready to go through to do it]].
** Kanase Kensei can also be seen as a [[SlidingScaleOfAntiVillains Type 3]]; [[spoiler: He genuinely believed that he could give Kanon happiness by letting her ascend to angelhood, and that she at the same time could prove a powerful force against a future threat.]]
* ArcWords: "That's enough for me." Spoken to Kojou on occasion by a girl whom he has just complimented or otherwise said something to bolster her esteem.
* BabiesEverAfter:
** Several of the women aboard Vatler's ship in episode 18 suggest this with Kojou. He immediately declines.
** In episode 23, [[spoiler:a time-traveling girl strongly resembling Yukina but with Kojou's eyes shows up. She also says some rather unusual things, such as calling Nagisa "aunt", and wonders if Yukina's nagging started at this point in time. She also demonstrates that she can quickly recover from injuries that would've been fatal for humans, and can summon a spear that looks like a golden version of Yukina's, and only stops short of saying she's their daughter due to Natsuki's interruption.]]
* BadassAdorable: All of the female cast are adorable, but this is especially the case for Astarte, Yume, Glenda and [[spoiler:Nagisa]], who are the youngest of the bunch. Played with in the case of Natsuki, as she is actually an adult, who only ''appears'' to be a cute young girl.
* BalancedHarem: The main heroine Yukina is [[TopWife at the top]], but Asagi, Sayaka and La Folia have decent development and screentime; Asagi barely edges out the lead amongst the three of them, with La Folia being next in line despite following Sayaka in appearance. Since Kojou needs several blood donors to summon and control familiars, all the girls get intimate moments with Kojou. Also, it's standard for a Progenitor to have a VampiresHarem [[spoiler:and indeed, time travel confirms Kojou will have a kid with more than one girl in the harem]].
* BareYourMidriff: Yukina's cheerleader outfit in episode 5.
* BedmateReveal:
** During ''The Labyrinth of the Blue Witch'' arc, a naked Sayaka wakes up to find herself sharing a bed with a naked La Folia. HilarityEnsues.
--> ''"Good morning, Sayaka. [[DoesThisRemindYouOfAnything You were wonderful last night...]]"''
** Asagi does this to Kojou in episode 6. When he wakes up, she's leaning on top of him. He responds by trying to fall back asleep, then asks her what she's plotting.
* BigBad: The overall villain of the entire story, whom the Fourth Progenitor has been created by [[spoiler: the Tengu]] to defeat is [[spoiler: Cain, the Father of Demons]].
* BigDamnHeroes:
** Kojou saves Yukina in episode 2 when Astarte begins to gain the upper hand against her.
** Kojou and Yukina do this to save Kanon in episode 12.
** Astarte saves Asagi and Sana from Kiliga in episode 17.
** Vatler does this for the two after Gigliora shows up and attempts to take out Astarte. However, whether it's this trope or VillainousRescue is debatable, since Vatler was mostly doing it because he wanted [[ItAmusedMe to see some action]], rather than out of the kindness of his heart.
* BigNo: Yukina lets one out at the end of episode 3, [[spoiler:after Kojou intercepts an axe-blow from Eustach, and gets decapitated for his efforts.]]
* BladeOnAStick: Himeragi's retractable weapon, Seikarou.
* BloodKnight: Christoph Gardos loves the thrill of war so much that he is trying to cause a war just for this reason.
* BloodSplatteredInnocents: Kojou's blood splatters on half of Yukina's face in episode 3 after he [[TakingTheBullet intercepts]] Eustach's axe attack intended for her.
* BreatherEpisode:
** Episode 5. While there is some action, it's not nearly as intense as in the previous two, and there are some lighthearted comedy scenes at school.
** Episode 9 starts off with some wacky high school hijinks, following yet another intense battle from the previous episode.
* CallingYourAttacks: Par for the course of any action series.
* CensorSteam: Used in episode 18 when Kojou is taking a bath aboard Vatler's ship, along with Asagi and Sana.
* ChildSoldier: Lion King's members like Yukina are all orphans who have been recruited from young age and formed to serve as weapons.
* ClingyJealousGirl: Yukina gets this the most. Asagi and Sayaka also have their moments.
* ConservationOfNinjutsu:
** When Kojou first faces off against a Nalakuvera, he has some difficulty with it. But once Christoph Gardos hops into the queen one, along with controlling several others, the heroes don't have much difficulty defeating them.
** The various prison inmates that escape in "Fiesta of the Observers" arc are certainly a threat, but as a whole, they're defeated rather easily compared to when it's just one villain attacking.
*** Interestingly, Aya Tokoyogi, the VillainOfTheWeek, makes short work of both Kojou and Sayaka, and kidnaps both Sana and Yukina at the end of episode 18.
* ContrivedCoincidence: In episode 17, Kojou, Sayaka, and Yukina discuss figuring out where Natsuki went. They then see Asagi on the television watching the Halloween Festa parade, and she just happens to be holding the hands of a little girl who strongly resembles Natsuki.
* CostumePorn: The animators love giving Yukina a change of clothes, sometimes several per episode. No other character in the series gets as many costume changes. In addition to her School Uniform(s), she's been shown dressed in: underwear, cheerleader uniform, party dress, yukata, birthday suit, Kojou's hoodie, maid costume, nurse outfit and gym uniform. Cop, cowboy, construction worker and Indian chief are probably left for the next season.
* CrouchingMoronHiddenBadass: Kojou isn't exactly stupid, but he is rather laid-back, lazy and generally lacking any drive or motivation in his daily life; definitely not what you would expect from one of the most powerful vampires in the setting.
* CurbStompBattle: Happens on several occasions.
** Typically Kojou and Yukina will be on the receiving end of one, but shortly afterwards the situation changes in their favor, and they end up dishing one out to the VillainOfTheWeek.
** At the beginning of episode 16, Vatler is taken out by a tiny girl, [[spoiler:Avrora using Nagisa's body]]. She gives him a warning and then leaves.
** Astarte takes out Kiliga rather easily once she shows up in episode 17.
* CuteBruiser: Yukina; see BadassAdorable further up.
* CutenessProximity: Yukina when she sees the stray cats Kanon and Nagisa were attempting to find homes for.
* DamselInDistress: Yukina suffers from this in episode 19.
* DeusSexMachina: Toned down; Kojou's BloodLust apparently activates through sexual arousal, meaning he needs to be aroused to suck blood and can lose control whenever it happens. However, it usually just takes fairly modest fanservice (such as panty or skin exposure from a girl) to get a reaction from him, so no real sex has been involved so far.
* DidYouJustHaveSex:
** When both Kojou and Asagi show up at school complaining about not getting enough sleep, Orin teases them about the possible reason.
** In Episode 21, [[spoiler:Asagi]] wakes up in Kojou's bed half-naked and starts to cry when she ponders what might have happened. [[ArentYouGoingToRavishMe She's disappointed when Kojou tells her the truth.]]
** As per usual, played with due to KissOfTheVampire:
*** Whenever Kojou shows up with a new familiar, [[ClingyJealousGirl Yukina is quick to question how he got it.]]
*** In Episode 19, Sayaka shows up to the final battle with her blouse buttoned wrong, which Yukina bitterly points out to her.
** A very straightforward example the OVA, where the BigBad villainess places Kojou under her control with {{Pheromones}} and later takes Yukina and La Folia hostage. She forces the mind-controlled Kojou to dote on her, and then notices that doing so is making Yukina jealous. Just as a TakeThat, she then orders Kojou to BridalCarry her into the bedroom. We never see what happened afterwards, and not knowing greatly bothers Yukina.
* DisproportionateRetribution:
** Stated to be this, in-universe. Kojou has to stop Himeragi from brutalizing some guys after they flipped her skirt. However, it's worth noting that she politely asked them to leave her alone and attempted to step past them several times. She only struck out at them after they ''grabbed'' her and pretty much yelled out "Where are you going, [[ThisIsForEmphasisBitch bitch]]?" Out-of-universe, no woman in her right mind would consider this "disproportionate".
** Played straight anytime Yukina hits Kojou for any acts of perversion, real or perceived. Even if it was entirely accidental.
* DistractedByTheSexy: Kojou gets hit with this from time to time, such as in episode 21 when Nina asks for his help while inside Asagi's nearly naked body. He agrees but [[PleasePutSomeClothesOn asks her to put on some clothing.]]
* DoesNotLikeMen: Kirasaka, to the point [[HatesBeingTouched she can't even stand their contact]].
* DoesThisRemindYouOfAnything:
** Vampires who have never fed on human blood are referred as "virgins".
** During KissOfTheVampire scenes, the girls say things like, "Not there, it hurts" or "Not so rough".
** When Kojou is ready to feed on [[spoiler:Sayaka]] the second time, she nervously says, "I'm not ready! I haven't even showered yet...!"
** [[spoiler: At the climax of the Empire of the Dawn arc, Kojou is feeding especially... energetically from Yukina, and her reaction is equally... energetic. Everyone present for this is looking around awkwardly, as if witnessing a couple passionately making out.]]
** See ThatCameOutWrong, below.
* DudeWheresMyRespect: Despite the fact that Kojou is an immortal monster who can literally wipe an entire city off the map with incredible ease, a surprising number of people seem to think it's a good idea to fight him. Justified in that he's still coming into his power, and that he's only able to win most of his fights with help due to inexperience.
* ElegantGothicLolita: Natsuki
* EnemyMine: Asagi and Sayaka are forced to work together to locate and rescue Kojou and Yukina in episode 10. Both of them are distrustful of the other, due to their relations and connections with him.
* EroticEating: Mimori Akatsuki eating a popsicle rather suggestively in episode 16.
* FakeFirstKiss: Yukina has her first kiss with Kojou because Kojou is a vampire whose powers only activate with sexual arousal (although Yukina [[{{Tsundere}} also in love with him, but denies it]]). During the incident in question, the two of them are trapped underneath layers of ice and facing certain death along with the astonishingly-beautiful [[PrincessClassic La Folia]]. La Folia (who is [[ChickMagnet also hot for Kojou]] tries to kiss him to get Kojou's power to awaken, but [[ClingyJealousgirl Yukina stops her and does it in her stead]].
* FalseFlagOperation: The "Free Terrorists" movement in the OVA tried to use one of [[spoiler: Aldegyr's]] battleship to crash the peace conference between [[spoiler: Aldegyr and Warlord's Dominion]]. Based on La Folia's words, seems like the terrorist group was secretly backed up by [[spoiler: North Sea Empire.]]
* {{Fanservice}}: Used on occasion throughout the show. The camera will sometimes [[MaleGaze pan and scan]] the particular female during that scene.
* FantasticRacism: The various supernatural races... don't get along. Because of their sheer age and power most Vampires look down both on humans and a subset of Vampires called Nosferatu who can't materialise Beast Vassals. There are also mentions of both Beast-men and Human Supremacist groups.
* FirstGirlWins: Asagi and Yukina are the first two female characters shown having significant interaction with Kojou. Come ''Strike the Blood EX,'' it's confirmed that [[spoiler: he's married to both of them.]]
* ForegoneConclusion: The "Empire Of The Dawn" arc reveals that [[spoiler: Kojou and Yukina ''will'' indeed get married and have a child. Moreover it also establishes that during the next 20 years Itogami Island will become a sovereign nation under Kojou's rule. TheStinger also reveals that Yukina is not the only woman to bear his child.]]
* {{Foreshadowing}}: At the start of the ''Labyrinth of the Blue Witch'' arc, Natsuki is seen dressing in the middle school girl's uniform, in order to catch a groper on the monorail. At the end of the arc [[spoiler: Natsuki is transformed into a little girl ''for real'' by a spell from the Witch of the Notaria.]]
* FreakyFridayFlip: Happens to Yuuma and Kojou in episode 13.
* FriendlyNeighborhoodVampire: Despite being a PersonOfMassDestruction and one of the most powerful vampires in the world, Kojou is in no way evil, and satisfies his BloodLust by drinking his own blood. In fact, when he became the Fourth Progenitor, his first idea of how to use his powers was to try to make the world a better place by focusing on {{Asshole Victim}}s, but he gave up on it and settled on trying to keep a normal life.
* GeckoEnding: The "Empire of the Dawn" arc is exclusive to the anime and makes up its ending. While it shows a glimpse of [[spoiler: [[DistantFinale the far future]]]] [[StatusQuoIsGod the status quo is ultimately maintained]], allowing for a possible second season to pick up where the anime left off.
* TheGlomp: Sayaka does this to Yukina in episode 6, while simultaneously pushing Kojou away from her.
* GodivaHair: Asagi in episode 21.
* GRatedSex: One of the recurring gimmicks of the show. [[KissOfTheVampire Vampire bites carry the same implications as sex]]. For example, a person who provides blood to a vampire becomes "blood-bonded", and being bitten on "unsafe days" can cause one to become a vampire. Possibly because of these facts, Kojou never bites or drains the blood of any person who doesn't want it--even an enemy. Furthermore, the interactions between Kojou and his "blood partners" during the bloodsucking invokes sexual imagery and eroticism. Other people who observe it also react the same way most would when watching a couple having sex.
* GoryDiscretionShot: Averted for the most part.
** [[spoiler:In episode 3, Yukina can be seen gripping Kojou's head when it detaches from his body after taking Eustach's axe attack.]]
** Eustach slices a demon in episode 2, with his chest wound visibly shown onscreen. In episode 4, he walks by the bodies of guards after Astarte dispatches them.
* GrandTheftMe: Koujou gets his body stolen by [[spoiler: Yuuma when she kisses him. This also leave Koujou stuck in a [[GenderBender girl's body.]]]]
* GratuitousItalian: Kojou does this in episode 1 to fool Yukina into thinking he's someone else.
* HamToHamCombat: Asagi and Sayaka do this in episode 10.
* HaremSeeker: Both a DiscussedTrope and InvokedTrope. Apparently, due to their immense power, charisma, and status, Progenitors are ''supposed'' to be this. The central axis of the plot is the appearance of a random Progenitor (Kojou) in Japan, which makes everyone around nervous about what he's going to do. Kojou himself wants no part of it, but everyone else around him from the Lion King Organization, to his own Familiars, to other vampires, continue to force this onto him. It's especially telling when there's a familiar that requires the blood of ''two'' people to work. [[spoiler: he forcibly marries (without consent) the first 10 girls the 11th girl (who he gets his kenjuu and the last girl, he makes an AguishedDeclarationofLove to and Yukina's insecurities about her current conditions make her reject him.]]
* HateAtFirstSight:
** Sayaka and Asagi. When they first meet, the former was beating up Kojou, who was suspicious of what he was doing with the latter. When they see each other again in episode 10, they immediately get into an argument again regarding Kojou. Poor Yaze is forced to be the peacekeeper as a result.
** Nagisa isn't too fond of Sayaka either for similar reasons. So when they see each other in episode 17, she immediately questions the latter's relationship with her brother. Kojou uses this opportunity to get Nagisa away, and pushes Sayaka towards Nagisa, who promptly leads her out of the room for further questioning on said relationship.
* HatesBeingTouched: Kirasaka, though only by men. [[spoiler:She appears to be able to make an exception with Kojou eventually.]]
* HeroStoleMyBike: In episode 17, Yukina slashes the chain off a bike at a convenience store after the half-track they were using runs out of gas. She says they'll apologize to the owner later on.
* HotterAndSexier: The OVA and Season II are both much less heavily censored than the first season.
* IdiotBall: Episode 20, [[spoiler: Kojou urges Asagi to leave the monastery right away but she wastes time complaining how she needs to find the earring she lost. When Kojou tells her he'll buy her replacement earrings, she wastes even more time asking what kind he'll buy.]]
* IgnoreTheFanservice: For someone so frequently accused of being a pervert, Kojou is hilariously indifferent and oblivious when Asagi ''actually'' tries to seduce him.
* IKnowYoureInThereSomewhereFight: Kojou does this for Kanon to help bring her back when she nearly lost the remnant of her humanity.
* ImpaledWithExtremePrejudice: Happens twice in episode 15:
** The first time is with Yukina stabbing Yuuma while the latter is possessing Kojou's body.
** The second time happens as TheStinger, [[spoiler:when Yuuma and Natsuki both get stabbed by Yuuma's guardian, who's being controlled by her mother.]]
** Kojou suffers one in episode 18 by Aya's familiar.
* InsecureLoveInterest: Almost every girl in the show fits this, especially when comparing themselves to one-another. Several times, when Kojou attempts to refuse drinking her blood, a girl will say something like, "Do you not find me attractive?"/"Am I not as pretty as [other girl]?", guilting Kojou into feeding on her.
* InTheHood: Kojou's favourite way to dress.
* InsistentTerminology: Natsuki ''hates'' it when the affectionate suffix of "-chan" (IE. "My cute little Natsuki") is added to her name. As she [[CatchPhrase often has to say]]...
--> It's Natsuki-sensei.
* IntimateHealing: Yuuma licks Kojou's finger after he cuts it from picking up the broken glass cup he dropped in episode 13.
* KissOfTheVampire: Played with; although still undeniably erotic as per usual with this trope, instead of an invasive rape-metaphor, the scenes in the Anime where Kojou partakes in the blood of his love interests are portrayed as surprisingly tender and heartwarming moments of sincere bond, trust and friendship. The gentle and romantic piano music used in said scenes really helps.
* LensFlareCensor: Used in the broadcast version of Episode 11 to cover Yukina and La Folia's lower halves.
* LittleSisterHeroine: There have been small hints that Nagisa harbors romantic feelings for Kojou. At one point, she laments that she's too old to bathe with him and, more strongly, she makes sexual advances towards him while under [[spoiler:Yume's influence--and Yume later ssays that her powers only enhance someone's deepest desires.]] For his own part, Kojou's overprotectiveness of/devotion to Nagisa often gets him accused of having a sister complex, particularly in the light novels.
* LoopholeAbuse: Yuuma uses this in episode 19 to help Kojou regain his powers, [[spoiler:since Aya Tokoyogi's powers weren't affected by the AntiMagic spell. And since Yuuma is a clone of hers, it won't affect her powers either...]]
* LoveLetterLunacy: Invoked a couple of times:
** The first is in episode 5, when Asagi catches Kojou holding a letter with Yukina showing off a LuminescentBlush. She immediately interprets it as this trope and runs off.
** In episode 9, Kojou and Yukina spot Nagisa talking to a boy and receiving what the latter thinks is a love letter. He doesn't take it too well when Yukina says that Nagisa is popular with the boys, and later on follows her to the school rooftop. They hear some rather suggestive sounding dialogue, then open the door, to find out they were [[spoiler:just talking about a cat.]]
* MaleGaze: Used occasionally throughout, such as when Kojou stares at Sayaka's chest in episode 8 after the latter has gotten wet.
* MakeMeWannaShout: Yaze's powers allow him to control sound.
* MarryThemAll: The final volume reveals [[spoiler: he's married to 12 girls.]]
* MistakenForGay: Asagi asks what may appear to be an ArmorPiercingQuestion regarding his status as a vampire, but instead she asks if he's into men, due to his apparent lack of interest in the various girls around him, along with being on somewhat too friendly terms with Vatler. Later, after he shakes the hand of one of Vatler's butlers, Asagi asks this again.
* MonsterSlayerRomance: Kojou is the Fourth Progenitor vampire and Yukina is a Sword Shaman sent to observe and potentially eliminate him should she deem him dangerous.
* NaughtyNurseOutfit: Yukina wears one in the "Fiesta For the Observers" arc. Mostly because Kojou's mother, Mimori, made her wear it to help to stabilize Yuuma after the latter was stabbed. While it's a fairly normal looking outfit, Kojou mentions that she looks really good in it.
* NiceJobFixingItVillain:
** Christoph Gardos forces Asagi to unlock the manual needed to activate and control the Nalakuvera. And he does it by giving her access to the latest supercomputer. Fortunately for the heroes, she puts her PlayfulHacker skills to good use, and installs a self-destruct program on the otherwise NighInvulnerable warmachines as well.
** In episode 19, Aya Tokoyogi creates a barrier that negates all superpowers and magical abilities on the island, except for her own. [[spoiler:Yuuma then exploits this to help Kojou recover, since she's a clone of Aya, so therefore her magical abilities aren't affected either.]]
* NinjaMaid: Astarte is made this by Natsuki after she is placed under her service.
* {{Nosebleed}}: Kojou has one whenever he gets sexually aroused. Interestingly, he takes ''advantage'' on it by drinking the resulting blood, such satisfying his own blood lust without having to harm anyone.
* NotWhatItLooksLike: Kojou is often in these sorts of situations, such as when he accidentally knocks Asagi off his bed in episode 6, and falls on top of her. Naturally Nagisa and Yukina both walk in at the same time, wondering what's taking her so long to wake him up.
* OffWithHisHead: [[spoiler: Kojou at one point gets his head brutally hacked off while attempting to save Himeragi. [[DisneyDeath He gets better]] [[GoodThingYouCanHeal quite fast]].]]
* OlderThanTheyLook: Natsuki looks like a grade schooler despite being 26.
* OhCrap: Yaze has this reaction in episode 10 shortly after he runs into Sayaka at the ruined church. He was trying to make a deal with her to find Kojou and Yukina, but then hears Asagi and Nagisa approaching, and isn't able to stop them from running into each other. A big HamToHamCombat ensues between Asagi and Sayaka after they meet.
* OneDialogueTwoConversations: In episode 8, Sayaka asks Kojou about [[DCupDistress "being big"]]. He says they are, but then mentions that some guys [[BuxomIsBetter like it big.]] She then clarifies that she was referring to her height.
* OneManArmy: According to Yukina, becoming the Fourth Progenitor made Kojou the equivalent of several armies put together.
* OurVampiresAreDifferent: [[DaywalkingVampire Sunlight]] doesn't affect them, they have Superpowered {{Familiar}}s inside of them, and apparently, they're immortal.
** Later volumes of the novels also introduce additional types. The first a "Ghouls" or "Nosferatu", less human looking Vampires who don't possess Beast Vassals but gain the ability to transform parts of their bodies into living weapons and a generally looked down on by regular vampires. There are also Blood Vassals, humans transformed into pseudo-vampires by grafting a regular vampires flesh into their body, similar to what Kojou did to Astarte but more permanent.
* OurWerebeastsAreDifferent[=/=]OurDemonsAreDifferent: Demons in this series (sometimes translated as Therianthrops) are portrayed as werebeasts.
* PeaceConference: In the OVA, it happened between [[spoiler: Aldegyr and Warlord's Dominion]]. [[spoiler: Good thing that it succeeded.]]
* PersonOfMassDestruction: Kojou, by virtue of being the Fourth Progenitor.
* PlayfulHacker: Asagi is a skilled computer expert.
* PoseOfSupplication: Yukina subjects Kojou to these a lot to reflect on his perverted acts. Especially if they were accidental and entirely out of his control.
* PrecociousCrush: Several of the girls crushing on Kojou are middle-school age. And two of the youngest are Astarte and Yume, who are grade-schoolers. Yume even asks Kojou to "wait" for her.
* {{Precursors}}: The Devas, an ancient race of superhumans who helped the original Three Progenitors create the Fourth Progenitor.
* PrimalFear: Nagisa goes into hysterics whenever an untransformed demon appears.
* RedEyesTakeWarning: Kojou's eyes ordinary are blue, but they turn red whenever he uses his vampiric abilities.
* ReiAyanamiExpy: Astarte, especially after her HeelFaceTurn.
* RomanceEnsues: A constant for this show, to the level of [[OnceAnEpisode Once An Arc]]. It only stops short of being CoitusEnsues due to KissOfTheVampire being used in place of actual sex.
** When Kojou and Yukina are defeated and try to figure out how to gain an advantage over the Combat Deacon, she suggests he take her blood and awaken a familiar.
** When Kojou and Sayaka are trapped in a chamber that will drown them in a matter of time, she suggests he take her blood and awaken a familiar.
** When Kojou, Yukina and La Folia are trapped in ice with murderous villains surrounding them on the outside, La Folia suggests that he take her blood and awaken a Familiar. [[SubvertedTrope Yukina stops her and offers herself in her stead]], but after she's asleep, [[DoubleSubversion La Folia is right back on it.]]
** When Kojou and Sayaka are alone after Kojou is mortally wounded by Aya, she suggests that he take her blood to heal. When she fails, Yuuma arrives and suggests the same thing using ''both'' their blood. [[ComboBreaker When Kojou doesn't heal, he realizes he needs to awaken a familiar.]]
* ScreamDiscretionShot: Typically used when Kojou is being punished for being a pervert, or rather [[UnprovokedPervertPayback Yukina thinks he's being one.]] Anything dealt in these situations is always PlayedForLaughs.
* SempaiKouhai: Yukina always addresses Kojou as senpai.
%%* ShesGotLegs: Yukina.
* SheIsNotMyGirlfriend: Kojou and Yukina repeatedly deny being a couple despite their obvious closeness and romantic attraction.
* ShockAndAwe: A fair bit of it, coupled with {{Yellow Lightning Blue Lightning}}. Kojou has his "Regulas Aurum" Familiar, a giant lion made of (yellow) lightning, whereas Yukina has two spells that enhance physical attacks with (blue) lightning. Her spear also generates what seems to be electricity when it pierces something as well.
** Subverted with Sayaka, then played straight: Her chant when using her magical arrows invokes a "god of thunder", but at first, only nullifies magic. Later, with the same incantation, she does indeed call down a barrage of (blue) lightning bolts.
* SingleWomanSeeksGoodMan:
** Yukina states that the reason her opinion changes about Kojou early on is because of his NiceGuy demeanor, and later says that his tendency to worry about others despite his own imminent danger is what she likes about him.
** La Folia's interest in Kojou piques when he shows concern over Kanase Kanon's endangerment. Specifically, at the exact time he makes it clear that he intends to save her before her mind breaks down completely, she literally throws herself at him. At several times, she asks that he prove she's "not wrong about [him]".
** Kanon first shows interest in Kojou after he pays her a compliment and helps her find homes for some kittens she'd been looking after. He later saves her life as well.
** Yuuma likes Kojou because his words and actions help her feel like a real person [[spoiler:rather than a tool programmed to do someone else's will]]. When he hits her with a KirkSummation at one point, she says that his ability to say the right thing so easily is what she's always liked about him.
** Yume falls for Kojou when he stops her from an elaborate suicide attempt due to the misery her succubus powers force upon her. He passionately proclaims that he will destroy anything that ever makes her unhappy ever again, which she chooses to interpret to mean "I will make you happy forever".
* SingleStrokeBattle: Yukina and Christoph Gardos in episode 8. She slices off his right arm, and declares the battle over. He agrees, but only because he still has Asagi and Nagisa hostage, as well as an army of Nalakuvera now.
* SkewedPriorities: It seems the girls in the show are usually more concerned with the other girls around Kojou, than the fact that there may be weird things happening, or a villain attacking the city.
** Sayaka gets into a HamToHamCombat debate with Asagi when they first run into each other in episode 10. Even after they locate where Kojou and Yukina are, they once again get into an argument about the other's relationship to him.
** When Kojou is first subjected to the random teleportation in episode 13, he unintentionally winds up in Yukina's bathroom where Astarte and Kanon are taking a bath. Yukina is much [[ClingyJealousGirl more obsessed]] that he saw the two girls naked, than the fact that he was afflicted with the same teleportation that Sayaka and La Folia went through.
** Nagisa gets extremely suspicious of Sayaka as well, wondering what her relationship with her brother is exactly. Never mind that Yuuma is dying on the couch in the room during that particular encounter. Possibly justified, though, in that the three times Nagisa has run into her, something bad has happened to one of Nagisa's friends, so she has good reason to demand answers.
* SortingAlgorithmOfEvil: The villains who attack throughout the show gradually threaten more and more of the city, and usually forces Kojou to obtain a new power to defeat them.
* SpitTake: Kojou does one in episode 21 after Asagi, who was taking a bath in his apartment, goes out of the bathroom while still naked.
* StealthHiBye: Several characters make use of this, showing up out of nowhere a lot of times. While it is utilized by the villains occasionally, it's more often played for comedic effect when Kojou says or does something around one girl, causing another girl to show up and put some ClingyJealousGirl retribution on him.
* TheStinger: At the end of episode 15, it seems all is well with Yuuma and Kojou. [[spoiler:Then her guardian [[ImpaledWithExtremePrejudice stabs]] her and Natsuki.]]
* SuspiciouslySpecificDenial: In episode 10, Yaze makes a deal with Sayaka. In exchange for her not telling Kojou and Yukina what his true identity is, he'd tell her where Kojou was. She blushes, looks away, and [[{{Tsundere}} vehemently denies]] wanting to hear anything about that. When he also mentions Yukina, she seems to change her tune, although Asagi and Nagisa approaching the ruined church interrupts the deal.
* TakenForGranite: Happens to the Nalakuvera in episode 8.
* TalkingIsAFreeAction:
** In episode 8, Yukina is explaining to Kojou and Sayaka about a new command Asagi threw into the Nalakuvera and how to destroy them. Christoph Gardos is polite enough to hold his forces back and not attack them while she's doing it.
** The Meyer witches also kindly wait for Sayaka and La Folia to finish their description of former's familiar, which is giving them a lot of problems. Once the two figure out how its nature, they exploit its weakness to defeat them.
* TeamworkSeduction: JustifiedTrope. Protagonist Kojou Akatsuki is a vampire whose powers only work if he drinks other peoples' blood, and vampiric bloodlust is akin to actual ''sexual'' lust, meaning he has to be turned on to drink blood. So this trope happens ''twice''.
** On one occasion, a familiar turns out to need ''two'' peoples' blood to work properly, so when one girl fails to do it alone, the other steps up to the plate as well.
** On the second occasion, this trope is fully invoked, both because a single girl can't arouse the dying Kojou enough to save his life, and because only one of them has blood immune to the AntiMagic field preventing his powers from awakening. So it takes one girl to restore his powers and the other to slake his thirst.
* TemptingFate: In episode 9, Valter asks Natsuki not to let Kojou get involved in the current situation, since he believes the latter wouldn't stand a chance against the new VillainOfTheWeek. Naturally, this assures that he will get involved.
* ThanksForTheMammaries:
** Kojou accidentally does this in episode 8 after Sayaka slips on some rubble and falls back on him.
** Mimori does this to Yuuma in episode 16. When Yukina inquires about it, the former says that fondling the breasts of cute girls is what activates her powers. Kojou immediately calls his mother out on this.
** Kojou trips again on Sayaka in episode 22, made even worse since he thought he was fondling the shikigami made by Yukina's master.
* ThatCameOutWrong: Sigh... What sweet and innocent little Yukina-chan ''tried'' to say to Kojou was "His ''bite'' didn't hurt too much, she didn't lose too much blood, it was a safe-day on the ''astrological'' cycle and hence the tests for her ''becoming a vampire'' came back negative. But [[SugarWiki/FunnyMoments paraphrased by Asagi who overheard the exchange]], it came out as:
--> '''Asagi''': "So you didn't hurt her too much, she lost a little blood, but it was a "safe day" so her [[TeenPregnancy "test"]] came back negative, huh?"
* TheCallKnowsWhereYouLive: Kojou honestly has no specific ambition or goal beyond "being left alone", but people keep coming in his life due to his status and end up bringing him into supernatural situations.
* ThoseTwoGuys: Invoked and PlayedForLaughs in episode 13. When Kojou is waiting for his childhood friend Yuuma to arrive, Asagi and Yaze show up uninvited as well. Yaze says that Kojou can just consider them "passers-by". So when Yuuma does show up, that's exactly how Kojou introduces them as.
* TopWife: In the OVA, La Folia is the first girl to propose to Kojou and claims to have no issues at all with Kojou's relationships with other women. However, when the subject of polygamy is raised, she brazenly offers Yukina the position of "second wife", though Yukina is without a doubt at the top of the food chain. This is later confirmed in Season 3, after accidentally Yukina becomes Kojou's "blood mate" after volunteering her blood one too many times. At that point, she becomes practically locked in as his number one spouse (although she and Asagi are still in competition) and La Folia seems to be satisfied with accepting a position as his concubine. Averted in the final volume as there is no heirarchy and kojou outright considers them his wives as hanryo aka companion is the female equivalent to wife in a vampires harem
* {{Troperiffic}}: Totally. An OrdinaryHighSchoolStudent blessed with the blood of the world's most powerful [[OurVampiresAreDifferent vampire]] teaming up with a [[BadassAdorable cute]] ActionGirl in order to fight powerful enemies threatening the fragile peace of their everyday lives, with a lot of action and magic tropes thrown in, as well as a few dashes of {{Fanservice}} and HaremGenre. Just looking at the character sheet's length is enough to give you a cue.
* VegetarianVampire: Kojou initially, in that he feeds on his own blood rather than drink others. It's the main reason why his familiars don't follow his orders.
* WhamEpisode:
** Episode 3 has a particularly brutal one. During their fight with VillainOfTheWeek Eustach, Yukina is on the receiving end of a CurbStompBattle. As Eustach raises his axe for a final blow against her, Kojou [[TakingTheBullet intercepts it]]. While it saves Yukina, [[spoiler:Kojou gets decapitated for his efforts.]]
** In episode 18, Kojou's familiar is banished, he's stabbed by Aya's familiar, and both Sana and Yukina are taken hostage.
** At the end of episode 20, [[spoiler:Asagi]] gets slashed from the front badly enough that Kojou thinks she's dead. However, [[spoiler: she survives due to the intervention of a new character, who heals Asagi ''and'' hijacks her body]].
* WhatDidIDoLastNight: The entire plot of the ''Missing Lance'' OVA. Turns out [[spoiler: it was caused by Kojou accidentally putting magic mushrooms in their hot pot. [[IntoxicationEnsues Intoxication]] and harem hijinks ensued]].
* WorstAid: Yuuma is stabbed with a massive sword [[spoiler: by her mother]]. Kojou and Yukina do not put pressure on the wound, or make any effort to stop the blood. When they take her to Kojou's mother for treatment, she delays the treatment further to catch up with Kojou, and [[DudeShesLikeInAComa fondle Yuuma's breasts]]. It's astonishing that the poor girl survives.
