The Fourth Progenitor—That's the world's strongest vampire that should only exist in legends. Accompanied by twelve Familiars and spreading chaos and mayhem, this phantom vampire appeared in Japan. In order to deal with potential threat, the government and 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 is a Japanese light novel series by Gakuto Mikumo of with illustrations by Manyako. A manga adaptation began serialization in August 2012 in ASCII Media Works's Dengeki Daioh. A 24-episode television anime adaptation by Silver Link and Connect began broadcast as a part of the Fall 2013 Anime season.Crunchyroll is streaming the anime, and can be viewed here by people living in the following areas: North America, UK, Ireland, Australia, New Zealand, Netherlands, Scandinavia, South Africa, Central America, South America, Caribbean, Turkey, Italy, Austria, Germany, Lichtenstein, Luxembourg, Switzerland, Belgium, Poland, Denmark, Czech Republic, Hungary, and Romania.
Accidental Pervert: Kojou frequently ends up this, especially toward Yukina. Her typical reaction is what you would expect from a Tsundere.
Aggressive Submissive: Roughly half of the female Love Interests 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.
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 weapons. Otherwise those things would go out of control, firing on both friend and foe.
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.
Anti-Magic: 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.
Kanase Kensei can also be seen as a Type 3; 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.
Arc Words: "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.
Several of the women aboard Vatler's ship in episode 18 suggest this with Kojou. He immediately declines.
In episode 23, a 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 mentions having the immortality curse, as well as wielding a golden spear that resembles Yukina's, and stops short of saying she's their daughter due to Natsuki's interruption.
Badass Adorable: Yukina is a straight example. Played with in the case of Natsuki, as she is actually an adult, who only appears to be a cute young girl.
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 Villainous Rescue is debatable, since Vatler was mostly doing it because he wanted to see some action, rather than out of the kindness of his heart.
Big "NO!": Yukina lets one out at the end of episode 3, after Kojou intercepts an axe-blow from Eustach, and gets decapitated for his efforts.
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 Villain of the Week, makes short work of both Kojou and Sayaka, and kidnaps both Sana and Yukina at the end of episode 18.
Contrived Coincidence: 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.
Costume Porn: 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, birthday suit, maid costume, nurse outfit and gym uniform. Cop, cowboy, construction worker and Indian chief are probably left for the next season.
Crouching Moron, Hidden Badass: 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.
Cry Cute: Yukina does this twice. Once in the third episode, when Kojou is beheaded and again in episode 22 when he's turned into metal.
Deus Sex Machina: Toned down; Kojou's Blood Lust 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.
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, 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.
Distracted by the Sexy: 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 asks her to put on some clothing.
Dude, Where's My Respect?: 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.
Enemy Mine: 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.
Erotic Eating: Mimori Akatsuki eating a popsicle rather suggestively in episode 16.
Fanservice: Used on occasion throughout the show. The camera will sometimes pan and scan the particular female during that scene.
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 Natsuki is transformed into a little girl for real by a spell from the Witch of the Notaria.
Foregone Conclusion: The "Empire Of The Dawn" arc reveals that Kojou and Yukina will indeed get married and have a child. Moreover it also establishes that during the next 20 years the Itogami Island will become sovereign nation under Kojou rule. The Stinger also reveals that Yukina is not the only woman to bear his child.
Friendly Neighborhood Vampire: Despite being a Person of Mass Destruction and one of the most powerful vampires in the world, Kojou is in no way evil, and satisfies his Blood Lust 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 Victims, but he gave up on it and settled on trying to keep a normal life.
The Glomp: Sayaka does this to Yukina in episode 6, while simultaneously pushing Kojou away from her.
G-Rated Sex: One of the recurring gimmicks of the show. 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.
Harem Seeker: Both a Discussed Trope and Invoked Trope. 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.
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.
Hates Being Touched: Kirasaka, though only by men. She appears to be able to make an exception with Kojou eventually.
Hero Stole My Bike: 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.
Ignore the Fanservice: For someone so frequently accused of being a pervert, Kojou is hilariously indifferent and oblivious when Asagi actually tries to seduce him.
The first time is with Yukina stabbing Yuuma while the latter is possessing Kojou's body.
The second time happens as The Stinger, 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.
Insecure Love Interest: 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.
Intimate Healing: Yuuma licks Kojou's finger after he cuts it from picking up the broken glass cup he dropped in episode 13.
Kiss of the Vampire: 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.
Lens Flare Censor: Used in the broadcast version of Episode 11 to cover Yukina and La Folia's lower halves.
Loophole Abuse: Yuuma uses this in episode 19 to help Kojou regain his powers, since Aya Tokoyogi's powers weren't affected by the Anti-Magic spell. And since Yuuma is a clone of hers, it won't affect her powers either...
The first is in episode 5, when Asagi catches Kojou holding a letter with Yukina showing off a Luminescent Blush. 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 just talking about a cat.
Male Gaze: Used occasionally throughout, such as when Kojou stares at Sayaka's chest in episode 8 after the latter has gotten wet.
Mistaken for Gay: Asagi asks what may appear to be an Armor-Piercing Question 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.
Naughty Nurse Outfit: 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.
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 Playful Hacker skills to good use, and installs a self-destruct program on the otherwise Nigh Invulnerable 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. Yuuma then exploits this to help Kojou recover, since she's a clone of Aya, so therefore her magical abilities aren't affected either.
Ninja Maid: 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.
Not What It Looks Like: 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.
Oh Crap: 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 Ham-to-Ham Combat ensues between Asagi and Sayaka after they meet.
Serious Business: 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 Ham-to-Ham Combat 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 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.
Shock and Awe: 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.
Yukina states that the reason her opinion changes about Kojou early on is because of his Nice Guy 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 rather than a tool programmed to do someone else's will. When he hits her with a Kirk Summation at one point, she says that his ability to say the right thing so easily is what she's always liked about him.
Single-Stroke Battle: 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.
Sorting Algorithm of Evil: 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.
Spit Take: Kojou does one in episode 21 after Asagi, who was taking a bath in his apartment, goes out of the bathroom while still naked.
Stealth Hi/Bye: 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 Clingy Jealous Girl retribution on him.
The Stinger: At the end of episode 15, it seems all is well with Yuuma and Kojou. Then her guardian stabs her and Natsuki.
Suspiciously Specific Denial: 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 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.
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.
Tempting Fate: 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 Villain of the Week. Naturally, this assures that he will get involved.
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.
That Came Out Wrong: 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 paraphrased by Asagi who overheard the exchange, it came out as:
Eh, so you didn't hurt her too much, she lost a little blood, but it was a "safe day" so her "test" came back negative, huh?
The Call Knows Where You Live: 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.
Those Two Guys: Invoked and Played for Laughs 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.
Troperiffic: Totally. An Ordinary High-School Student blessed with the blood of the world's most powerful vampire teaming up with a cuteAction Girl 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 Harem Genre. Just looking at the character sheet's length is enough to give you a cue.
Vegetarian Vampire: 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.
Episode 3 has a particularly brutal one. During their fight with Villain of the Week Eustach, Yukina is on the receiving end of a Curb-Stomp Battle. As Eustach raises his axe for a final blow against her, Kojou intercepts it. While it saves Yukina, 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, Asagi gets slashed from the front pretty badly. However, she's gets better in the next episode, other than some torn up clothing.
Worst Aid: Yuuma is stabbed with a massive sword 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 fondle Yuuma's breasts. It's astonishing that the poor girl survives.
