Hagi and Saya, with a Chiropteran in the background.
Saya Otonashi is seemingly an Ordinary High-School Student in Okinawa, aside from her amnesia and anemia. All she wants is to compete in track and spend time with her American adopted father George and her (also adopted) brothers, moody Kai and innocent Riku. However, Saya's world changes forever when she's attacked by a Chiropteran, a hulking, bat-like humanoid monster. This prompts a rescue by Hagi, a mysterious, handsome stoic who seems devoted to protecting Saya. Hagi kisses Saya, forces her to drink his blood, then gives Saya a sword coated with her own blood. This event cause a strange transformation in Saya; her eyes glow red and she becomes a fighting machine, quickly killing the Chiropteran. Afterwards, answers are refused while even more strange accidents occur all around Saya; eventually, she is forced into leaving her home to help a secret organization called Red Shield stop a mysterious entity only known as Diva. However, not everything is black and white, and Saya soon begins to doubt her reasons to fight, her allies, and her own humanity.Blood+ is a 50 episode long anime which is loosely based on the OAV Blood: The Last Vampire; the film and the series share the basic premise, the characters of Saya, David and Lewis (all of whom are re-imagined in Blood+), and the Chiropterans, but otherwise have little in common.If you live in North America, you can watch this series on Crackle (Here), Hulu (Here), and YouTube (here).If you are even remotely interested in watching the series for yourself without any spoilers, stop reading NOW. Most spoilers are covered,but a decent amount aren't.Seriously,don'tscroll down the page. Don't even think about Googling the series name or checking out the subpages until you are finished watching the series either. You Have Been Warned.
Abnormal Ammo: The ignition rounds Kai uses latter in the series. Shooting explosive rounds into a Chiropteran followed by a primer shot made the guns suddenly become slightly less useless.
Affably Evil: Solomon may be one of Diva's henchmen, but he's a pretty decent guy overall. He's a peace loving person, and actually cares for his chiropteran "brothers." Nathan as well; in fact, he's more affable than evil.
All Love Is Unrequited: Solomon for Saya, Karl for Diva and then Saya, possibly Kai for Saya, Mao for Kai (at first). The list goes on.
Collins' entire reason for betraying the Red Shield for Diva's group was because he wanted to make his findings about chiropterans public, which the Red Shield refused to let him do.
Everything Amshel does is because of his desire to find out everything he possibly can about chiropterans, and if that means overstepping all kinds of moral bounds and nearly causing The End of the World as We Know It, it's a small price to pay.
America Saves the Day: Subverted; though many of the central characters are Americans, the American military and government as a whole is not depicted as benevolent or well intentioned.
Bittersweet Ending: True, Diva is defeated and the Chiropteran threat has been ended, and Saya can finally live her life without fighting and killing. Unfortunately, she'll have to go through thirty years of hibernation first, and will miss out on a lot of the lives of her family and friends in the process.
Boomerang Bigot: Saya has little more than disdain for most other Chiropterans despite being one herself. Shown more prominently in the manga; she even explicitly tells Riku, her own little brother, that she's going to eventually kill him just for being a Chiropteran.
Bratty Half-Pint: Hagi when he first met Saya. Granted those circumstances would make anybody grumpy.
Also, Hagi. Through a flashback, it is shown that the reason he went from being somewhat stoic to made of stone was because his blood turned his One True Love and reason for living into a murdering psychopath who forgot who he was and cut his arm off during her rampage.
Breather Episode: The return to Okinawa after Vietnam and the shopping trip in New York.
Brown Note: Diva's singing can get deadly under the right circumstances
Bury Your Gays: Subverted in that Nathan survives 'til the very end, outliving his boss, associates, underlings and several main characters. After Saya cuts him in half. He makes a passing statement that implies that he is not actually Diva's chevalier, but the chevalier of Saya and Diva's mother. Saya's blood might not have ever been a threat to him. If this is true, Nathan would be completely impossible to kill, unless Saya and Diva's aunt (who must have existed since Chiropteran queens are always twins) is still out there somewhere.
He's killed in the manga after he murders Diva due to pent up rage from Diva's indifference over James' death.
But Not Too Foreign: A non-human example. Saya was born and raised in France, but can easily pass herself off as a native Okinawan.
Children Are Innocent: Riku. Face it, if Kai was the one who had his blood drained by Diva and became Saya's Chevalier only to get raped and killed by Diva, it wouldn't be quite as traumatic for the cast or the audience.
Drama-Preserving Handicap: For her final confrontation with Diva, Saya was being gradually weakened since she was starting to enter her hibernation cycle. If not for that her superior fighting skills would have ended the fight in seconds.
Dress Hits Floor: The pivotal scene between Diva and Riku in the episode 'Boy Meets Girl'.
Subverted. All of the Chevaliers appear to be Extreme Doormats, but they actually aren't. Ultimately, Hagi wants to fulfill Saya's wish, but he doesn't coddle to her every whim and is perfectly capable of disagreeing with her in order to protect her. The other Chevaliers are almost the opposite. They spoil Diva by giving her every little thing she wants, but they are primarily motivated by selfishness and continually manipulate her for their own benefit.
Eye Scream: Hagi stabs a Chiropteran in the eye in the first episode.
Face-Heel Turn: Dr. Collins betrays Red Shield to work for Cinq Fléches, taking Julia with him. Julia eventually  rejoins Red Shield, with some prodding from David.
Face Stealer: Chevaliers and Queens have the ability to take the form of somebody whose blood they have drunk. Diva uses it for extra Squick when she goes around looking like Riku.
Fantastic Racism: James' hatred of the Schiff. Particularly ironic, given that he is a black American. Becomes even more ironic when James is saved from certain death...by replacing most of his body with Schiff parts. Of course, this makes it worse; self-hatred makes him lash out, and he blames the Schiff for the fact that Diva is disgusted with James's own Schiff transplants.
Feed the Mole: Amshel tells Solomon Diva will be at Christina Island to shoot a video in a week. The latter told Red Shield, who arrived on the island. By that time, Diva left the island. James was waiting for them.
For Science!: Amshel's ultimate motivation behind being Diva's Chevalier and the Delta-67 project is because he wants to better study Chiropterans.
For Want of a Nail: Saya and Diva are twin sisters. Joel raised Saya like a daughter, whereas Amshel kept Diva locked in a tower, treating her like an experiment. When Saya receives this history lesson, she can't help but sympathize with Diva, knowing full well that they could just as easily wound up with their roles switched.
Freudian Excuse: Diva's so fucked up because she spent her life as a test subject locked in a tower. And only received anything like human contact from a person that saw her as a specimen. Her feud with Saya stems from the fact that she seeks revenge for how their adoptive father, the first Joel Goldschmidt, callously neglected her at the same time he raised Saya in freedom and luxury.
Go-Go Enslavement: After losing consciousness because of a fight, Saya is abducted by Solomon and stripped of her clothes in her sleep. He claims it was because they were ruined. However, he gives her a nice gown after she does wake up.
Go Out with a Smile: Diva's dying act is to smile at and caress her cocoons of her unborn daughters.
Good Old Ways: Hagi, and Riku once he becomes Saya's Chevalier, if only in clothing styles.
Good Is Not Nice: David certainly counts, at least early on. He beats Kai senseless to teach him a lesson on what kind of world they live in and forces Saya to fight despite full knowledge that it's tearing her apart.
Good Thing You Can Heal: Sapient Chiropterans in general. Saya takes advantage of it in a battle against Karl running herself through to stab Karl and poison him with her blood. Diva once got shot on purpose just so Amshel would buy her a new dress. And Hagi seems to get Impaled with Extreme Prejudice at least every other fight.
Guns Are Worthless: Bullets might slow a Chiropteran down, but to kill them you need Saya — or at least her blood. Beheading and incineration also work, but these aren't exactly things that can be accomplished with firearms, and are generally nigh-impossible for ordinary humans to pull off anyway.
Encasing them in concrete and sinking them to the bottom of the ocean seems to be the preferred method of dealing with them semi-permanently. Of course, this only works if you can manage to trap them into a strong cage before pouring in the concrete.
With the ignition rounds that Kai uses after the Time Skip, they become slightly less useless in a fight.
Happily Adopted: Saya, Kai and Riku when living with George. Too bad it didn't last.
In the epilogue, Diva's children living with Kai.
Happiness in Slavery: For at least the first 2/3 of the show, Haji embodies this trope perfectly: a servant that is completely and utterly loyal to his master, because as a chevalier he's biologically hardwired that way. Then it turns out that chevaliers can betray their queens and abandon them without remorse; Haji is simply that devoted to Saya.
Healing Factor: Saya's wounds are known to heal exceedingly fast, along with Hagi- though their rapid healing rate is only based on the amount of blood they consume. i.e. Saya's wounds will heal more rapidly after drinking human or Hagi's blood, and Hagi's wounds will heal after drinking human blood.
Heroic BSOD: Saya and David, after Diva's mid-series Moral Event Horizon moment. David spends the Time Skip and several episodes after it as a drunken mess, and Saya attempts to distance herself from her friends and family to avoid the pain of losing any more loved ones. Both eventually snap out of it.
Heroic Willpower: Saya managed to hold back her approaching hibernation cycle long enough to kill Diva and return to Okinawa.
Idiot Ball: Early in the series, Kai follows Saya to Hanoi after getting his ass handed to him by a simple Red Shield operative, and being shown that he would be worse than useless in a fight against the supernatural fiends Saya fights on a day-to-day basis. Even worse, he drags their younger brother along with him. He then proceeds to barge in during the middle of a dangerous fight and purposefully snaps her out of berserker mode for no apparent reason because he can't stand to see his adoptive imouto Saya as a bloodthirsty killing machine.
Instant Expert: Saya is initially confused by her sudden aptitude for sword fighting and languages. Subverted in the fact that she isn't learning new skills, just remembering ones she already had.
Instrument of Murder: Hagi borders on this trope. He regularly uses his cello case as a weapon/shield. The cello itself is only used to perform music. One does have to wonder how it hasn't been smashed to pieces inside his case though.
Intimate Healing: To heal, queens recieve blood from their Chevaliers. This is typically a fairly intimate process. See also Kiss of Life, below.
I Work Alone: Saya develops this attitude after the Time Skip as part of her Heroic BSOD, refusing to work with her pals in the Red Shield because she doesn't want to endure the pain of losing any more friends and loved ones. She snaps out of it eventually.
first subverted, given that one does not expect Riku to survive his first encounter with Diva, then tragically untwisted, given that one does expect him to survive his second encounter with her.
Averted in the manga where he lives.
Charles in the manga.
Kiss of Life: Played with; to awaken Saya's Chiropteran powers to save her from the first Delta-series Chiropteran she encounters, Hagi gives her some of his blood by putting it into his mouth and kissing her. This is later revealed to be a sort of Meaningful Echo of how she turned him into a Chevalier in the first place, giving him some of her blood to save his life after he fell off a cliff-which ironically was her fault, since she tried to grab a flower over the edge just to give it as a birthday present to the first Joel.
Kiss of the Vampire: Several of the reactions, Nathan's in particular, suggest that a queen's bite can be quite... pleasurable.
Knife Nut: In addition to his cello case, Hagi has a seemingly unlimited supply of throwing knives.
Laser-Guided Karma: Played straight for both sides. In their final showdown, Diva and Saya stab each other with their blood, which normally would have killed both of them, but Saya survives because Diva's pregnancy made her blood lose its potency.
Light Is Not Good: Solomon, who wears white and has an angelic appearance (that is, until he leaves Diva's side, however, even that has nothing to do with any sense that trying to kill off all or most of humanity is wrong. He just decided that he liked Saya more.
Diva as well. Pale pretty girl with blue eyes, wears white Victorian clothing, is a opera singer and often described as a angel. Bad side? She is a century and a half old Chiropteran Queen who has killed thousands of people, participated in a experiment to create a virus to turn others into chiropterans, had figures such as Gregory Rasputin and Martin Bormann as her chevaliers, meaning she was involved in, if not being the mastermind of, the Romanov Massacre (As she also impersonated Anastasia) and WWII. Should I also mention she raped a 14-year old boy to get pregnant and then killed him, all for the sake of pissing off her sister? Also, when she sings, people turn into monsters.
Lighter and Softer: The manga - pretty much nobody dies, in stark comparison to the anime.
Also Darker and Edgier in the sense that it is more perverted (inappropriate panty shots abound) and there is plenty of nasty gore.
The Load: Played straight and averted with Kai and Riku. At the beginning of the series, neither have much fighting skill and mostly hindered Red Shield. On many occasions, though, they gave Saya some required emotional support in order to fulfill her tasks. After the destruction of Red Shield, Kai trains and becomes an important part of the team, being able to fight as well as counsel those in distress.
Cinq Fleche employs a few of others such as Boris (creator of the Schiff) and Van (who worked to perfect Delta 67)
Major Injury Underreaction: Avoided. Several Chevaliers avoid any major reactions when they undergo injuries. These injuries include Solomon and Hagi having arms sliced off and Solomon having a giant hole ripped through his stomach. However, many of these aren't major injuries in the first place as they heal extremely quickly.
Possible example with the name Hagi. In Japanese 'Haji' can mean 'shame' or 'guilt'. This is meaningful as it is a possible explanation for why he becomes such a Stoic after the Vietnam incident. Indeed, Word of God states that feeling responsible for what happened is the reason he is a more subdued character by the time Saya meets him again in the first episode.
Mega Corp.: Though Cinq Flèches is largely described as a pharmaceutical enterprise, it has enough resources to be active in other industries, such as technology, food production, military contracting, and, of course, Chiropteran-based genetic manipulation. They even own and run an all-girls high school in Vietnam.
A Million Is a Statistic: People didn't start to lose sympathy for Diva, despite the hundreds of people she killed, until after she raped and killed Riku.
Muscles Are Meaningless: Both Saya and Diva are tiny, but still able to hold their own. Saya can chop chiropterans in half with ease, and Diva was able to actually throw Saya clean through a brick wall without even trying.
My God, What Have I Done?: Van towards the end of the series after witnessing Delta 67 turn many members of the public into Chiropterans.
Naked on Arrival: How the Chiropteran queens emerge from their hibernation cocoons.
Nice Job Breaking It, Hero: Saya is responsible for unleashing Diva on the world. In her defense, however, she had no way of knowing what would happen, and it was more the original Joel and Amshel's fault that Diva became that way anyway.
Nigh-Invulnerability: Queens and their Chevaliers are capable of quickly healing almost any wound. This includes being impaled through the stomach with a tree trunk, stabbed with many large sharp implements and having arms cut off. If bad turns to worse and they are poisoned by Saya's blood, Chevaliers have the option to amputate themselves and obtain replacement limbs.
The Only One Allowed to Defeat You: Saya considers it her personal duty to kill Diva, not merely because she's the best suited for the job, but also because she was the one who released Diva in the first place.
The Ophelia: Diva really has the whole package going for her. Long hair, prone to sing songy babbling, broken princess.
Our Vampires Are Different: Definitely one of the better uses of this trope and one that shows some real creativity. It's really a complete reinvention of the vampire archetype; they are a completely different species (rather than merely former humansnote Ok, the Chevaliers are, but they can't exist without the queens.), with a hive-like social hierarchy and reproductive method.
It's worth noting that the Schiff, artificial chiropterans developed in a laboratory, are about as close as this series gets to traditional vampires. They look human, have superhuman strength and speed, need blood to survive, and burst into flames if they're exposed to direct sunlight for more than a few seconds.
Power Degeneration: The Thorn for the Schiff, which slowly crystallizes their bodies. Saya goes through this when she approaches her hibernation cycle, suffering fainting spells and a weakened healing factor. And Nathan reveals that Diva also suffered this as a result of her pregnancy, hence why her blood didn't petrify Saya when the two stabbed each other at the end of their Final Battle.
Psycho Rangers: The Corpse Corps are this for the Schiff. Despite undergoing similar treatment and brutal training, those of the Corpse Corps are emotionless, thoughtless, cold-blooded killers who will stop at nothing to achieve their goals as given by their masters. It's no wonder Moses freaks out when he sees who are really behind the masks.
Red Eyes, Take Warning: Saya's eyes are a dull shade of red, but turn bright, glowing red when she uses her vampiric abilities. Diva, the main antagonist, has blue eyes which also glow brightly when she's serious.
Spoiled Brat: Saya (initially) thanks to Joel's superficial attempts at parenting. Meeting Hagi got her to mellow out into Spoiled Sweet.
Spoiler Opening: If you pay attention to the background before the chorus starts in the first opening, you'll see a significant plot point for the last 13 episodes of the series.
Stealth Pun: A feature found on some swords is commonly known as a "blood groove", but rarely so literally as in this series.
Stuff Blowing Up: The preferred method of dealing with accidents is 'Option D', which means dropping missiles on the affected area. On a smaller scale, Kai uses special bullets which ultimately cause parts of Chiropterans to explode.
Super Soldier: The Delta-series and the Schiff were failed experiments in creating artificial Chevaliers to serve as super soldiers. Ultimately, they succeeded with the Corpse Corps.
Stalker with a Crush: Solomon and Karl both have this for Saya, although to different degrees. Solomon wants Saya to love him, while Karl wants to kill her while she kills him. Diva had also developed this kind of obsession with Riku after she met him.
This was also Mao's initial reason for following Kai across the world.
Taken for Granite: Any Chiropteran killed by the blood of the opposing queen, as well as Schiff who die of the Thorn.
Taking You with Me: In their final battle, Karl attempts to completely drain Saya of her blood, which would kill him as well, in the hopes that they would die together. Saya doesn't go for it. Ditto with James and later Amshel.
Those Two Guys: Kakimoto and Kato, Kai and Mao's friends back in Okinawa. Their relevancy to the overall plot is about the same as air.
Thicker Than Water: Subverted. One may expect Saya to abandon her adopted brothers after discovering she's a Chiropteran and live with them. Instead, she decides to stay and fight as she feels the former are more important to her.
Riku in the manga after the time skip, especially after learning of Charles' death, and Saya's plans for Diva.
Tragic Keepsake: Kai wielding George's handgun, Joel's dysfunctional watch, Saya's sword when it becomes reforged with a crystal from her adopted father, and Kai's necklace which contains a crystal from Riku.
True Companions: The members of Red Shield, especially later in the series.
Three-Month-Old Newborn: The newborn Saya and Diva are described in Joel's diary as looking like two-month-old human babies. Diva's daughters are a better example; from the minute they emerge from the cocoons, they have full heads of hair, and are cooing, smiling, and even giggling. Justified, since in both examples, the babies aren't human.
Violence is the Only Option: Subverted. When Kai brings Irene back with him to just ask Saya if the Schiff can have some of her blood, Saya's response is to attack Irene. Kai and David talk her out of it and she agrees to give her blood to help Irene. And then the rest of the Schiff show up and think Irene has been captured and they start fighting again. This time it is Irene who talks them down.
Weak, but Skilled: Since Saya and Hagi get their blood from transfusions instead of eating humans like Diva and her Chevaliers, they aren't as physically powerful. They can still go toe to toe with them thanks to martial skills and teamwork.
Unskilled, but Strong: Diva contrasts this. She's nowhere near as skilled as Saya, but she's so strong and fast that she doesn't really need them.
What Measure Is a Non-Human?: The Red Shield has little qualms about killing any and all chiropterans who aren't working with or for them (i.e. Saya and Haji), and neither do Saya and Haji. It's shown on multiple occasions that many chiropterans are capable of human emotions and have some form of conscience, but they don't seem to care: if they're out harming humans, they have to die. In the manga, Saya even explicitly tells Riku, her own brother, after his conversion that she's going to kill him simply for being a chiropteran.
