"Humans feed on birds and cattle, Vampires on the lifeblood of Humans. Didn't it ever occur to you that there might be something yet higher on the food chain?"
Trinity Blood originally began as a series of Light Novels penned by the late Sunao Yoshida, which were later adapted into a manga and anime series. The manga is known for its lush and Baroque artwork by Kiyo Kûjô; and the anime adaptation is similarly lavish in its visuals and animation quality.The anime continuity opens on a time far into the future, 900 years after a disaster which nearly destroyed Earth's population. The Catholic Church has re-emerged as a major military superpower and is currently waging a Cold War against the Methuselahs, a vampiric race comprised of humans which have been infected with an alien bacillus. (Said bacillus prolongs the victims' lives, grants them magical powers and super strength, at the cost of being vulnerable to sunlight — and leaves them constantly hungry for human blood, hence the reason they're considered such a nuisance.)It is not uncommon for stark, be-trenchcoated heroes to emerge during times like this. However, the main be-trenchcoated hero of this story appears anything but heroic at first glance. In fact, Father Abel Nightroad seems a bit of a ditz, although under the right circumstances, his true form will show itself. (His true form being that of a Crusnik, a powerful and monstrous being which feeds on vampires the way vampires feed on humans.)The series isn't just about Father Nightroad kicking vampire ass for the Lord, though. There's also plenty of intrigue going on in both the Vatican and Methuslean camps. And a shadowy conspiracy called the Order of Rosenkreuz, which seeks to bring about The End of the World as We Know It. Again.It's probably worth noting that one of the reasons the anime is so light on content, and that the manga is sort of... hanging... is because the original author died before the series could be finished. And the mangaka aren't really sure how to finish the series well enough so as to honour the author and keep the fandom happy.
All There in the Manual: Seriously. The show tells you almost nothing about the setting and backstory. The manga is more clear and forthcoming about these details. The novels are your best bet if you want to have a clue what's happening, though. There's also the notes left by the original author prior to his death which explains the events after Esther was crowned Queen of Albion. But those events got worse .
Author Existence Failure: Sunao Yoshida died at the age of 34, with the novel series incomplete and the manga adaptation not even begun yet. His best friend Kentaro Yasui took over on both. Nobody bothered to take over the anime, which ended with a 1st-season cliffhanger, though. The manga is still ongoing though.
A Child Shall Lead Them: Pope Alessandro XVIII, King Ludwig II (in the novels) and Empress Seth. The former is timid and easily manipulated; the second is a genderconfused 15 years old wheelchair bound ruthless king of Germanicus; and the the latter is Really 700 Years Old but rules through a proxy due to her youthful appearance.
Crash into Hello: Abel and Esther. Although Abel thought she was a boy when they met.
Crapsack World: Before the events of Trinity Blood, the humans and the Methuselahs (who were orignally humans and colonizers of Mars but got infected with the bacillus) wage war against each other which almost destroy the entire human race and the planet. During the events of the series, humans and Methuselahs still hold antagonistic feelings against each other. According to the original author's notes, it got worse
Cursed with Awesome: ... which is what infection of the Bacillus would be if it didn't require the constant craving for human blood. Given the wondrous powers it bestows, one wonders why all or part of humanity doesn't allow itself to be infected and then just survive on a diet of synthetic blood. Lampshaded during the fairy synthetic vampires arc: it said that the successful conversion rate is extremely low (at least in the light novels).
Demotedto Extra: The anime reduced some of the characters' roles. For example, Mary Spencer has a very prominent role in the manga and novels where she is the illegitimate daughter of Crown Albion Prince (making her and Ester as sisters) and a possible successor to the throne. The anime never mentions this.
Hungarian words and names occasionally crop up untranslated, especially in the manga continuity. Justified, though, since Esther is a naturalized citizen raised in Istvan, a Hungarian border city which a handful of story arcs center around, and, presumably, picked up Hungarian as her first language.
Altum Videtur: Aside from the assumption that most characters affiliated with the Vatican probably speak Latin via Translation Convention, there's also Contra Mundi, whose name and motto are often dropped entirely in untranslated Latin.
Gratuitous German: Scanlations of the manga tend to have Deitrich throw in a word or two, and even complete phrases, of German into his dialogue for no reason in later chapters.
Love Hurts: When it doesn't make you evil or is unrequited, happy protagonists and villains in this series have to deal with the demise of their spouse/lover: Like William and his fiancé, Helga and her husband, Monica and her husband, Leon and his wife, Gyula and his wife Maria, Abel and his beloved Lilith.
Caterina Sforza in the novels and Manga. When Abel shows too much concern on Esther for her liking. She subtly moves to arrange Esther's accidental deathtwice. Later on, in Stories Untold, she realizes the grave consequences of her actions and uses this hatred and jaded love to win herself a place in the Orden, in order to destroy them from within.
Abel, Cain, and Seth Nightroad: Obvious reference to the three sons of Adam and Eve.
Lilith Sahl: Reference to Lilith, Adam's first wife in some interpretations of Genesis.
Esther Blanchett: Reference to the biblical queen Esther. Also lampshaded by Dietrich as being homophonous to Greek "Aster," or "star." Revealed to be Esther White in the manga, the White Rebellion.
Edward White is not her biological father, but a knight faithful to the Crown Princess who saved Princess Esther and was framed by the real conspirators of the crime. Also Blanchett/Blanchette is a French heroine of a novel with the same name. Also also, "Blanchett" approximately translates from French as "Little White," and Albion, one of the traditional, poetic names of Britain is etymologically related to Latin "albus," or "white."
Radu Barvon Named after Vlad "The Impaler" Tepes' traitorous brother, he was the puppet ruler of Wallachia whenever the Ottoman Empire occupied it.
Hercules Tres Iqus: Number 3 out of 10 (Iquis is Latin for "X", or in numeral form, "10") Killing Dolls created by Geppetto Garibaldi.
Augusta Vradica: Augustus Caesar meets Vlad Dracula
Astharoshe/"Asta": Reference to Ashtoreth/Astarte, a Canaanite goddess mentioned in the Old Testament, and namesake of Astaroth, a high-ranking demon in Medieval demonology
Suleyman: Reference to Suleiman the Magnificent aka Suleyman I, the longest-reigning Sultan of the Ottoman Empire.
All codenames (Except maybe Dandelion?)
Nope, even Dandelion. He's a dandy, and his name is Leon. That's it.
In fact, Dandelion translated to Spanish is "Diente de León", that can be literally translated to "lion's tooth".
All members of the Vatican are connected to Renaissance important politicians or members of the Church: Borgia, Caterina Sforza, Medici, Alphonso D'Este.
The nicknames "Calamity Jane" and "Bloody Mary".
Baybars/Baibars is a reference to another famous sultan known as Abu al-Futuh.
Abel has imposed one on himself. His Evil Twin hasn't, and the results show why Abel has done so.
Seth and Lilith limited it too. Since releasing 100% power would mean the Nanomachines taking possession of the host which is what happened to poor Cain. Sadly, the Anime forgets this fact and the other little detail that Lilith has no nanomachines in her bloodstream or she won't be dead ''or that Abel got his head blown off to be in stasis during Throne of the Roses.
Pre-Asskicking One-Liner: Whenever you hear Abel's voice change uttering the words, "Crusnik 02. Nanomachine output 40%. Activate," you know someone is about to get wrecked in a horrific manner.
Special mention must go to Seth and Mirka, who are ancient but look about the same age as Ion. What's really striking is that Mirka is Ion's grandma!
The Reveal: Big time in episode 19, in which Seth is revealed to be The Empress, while The Empress is revealed to actually be Mirka Fortuna, Duchess of Moldova. In all fairness, there was a bit of a Chekhov's Gun that should have at least clarified who Seth really was: at the end of episode 11, you see the bottom portion of her head, revealing her childlike face and giveaway hairstyle (not to mention her voice when she speaks).
Romantic Two-Girl Friendship: Shahrazad and Esther are a rare inversion, because Esther had 'romantic friendship/partnerships' with a lot of men (Dietrich, Abel, Ion) before 'graduating' from them and establishing one with a true sense of lasting commitment with a girl. Too bad Shahrazad dies minutes after Esther realizes this..
Say My Name: Esther and Ion, stuck in a cell together. You wouldn't think they'd have to cry out the names, what with being in the same cell, but they do.
Screw the Rules, I'm Doing What's Right: In the episode Overcount I. The Belfry of Downfall Cardinal Caterina Sforza breaks Vatican protocol in seeking to stop a weapon that could destroy all of Rome. As a result she placed under house arrest and is hinted that that she might have been executed. However, she is cleared when the weapon is used.
Sexy Priest: The AX agents seem to be ranked according to how attractive they are. Abel of course is first. Tres may be an exception, as he was designed that way.
Shotacon: Ion Fortuna. The anime ending has hints of Abel×Ion.
Oh, Brother Petro. "I'm merely been assigned to be His Holiness's escort! It's not as if I'm on another mission and have been sworn to absolute secrecy or anything! Because I am definitely not! Don't get the wrong idea!"
Also the Duke of Tigris: "W-Whatever do you mean? Why would I ever blow up Your Majesty?"
Tarot Motifs: an entire tarot deck released with the DVD box sets.
Technical Pacifist: Abel in the anime. He's rather less disturbed by killing in the novels and manga.
Astharoshe "Asta" Asran, and using that nickname without permission is an easy way to trigger the tsuntsun side. Ion Fortuna. Esther Blanchett to a degree is a tsundere type B, usually she's polite and kind, but she has her triggers specially around Abel in the novels.
Vanessa Walsh as well.
Unknown Rival: Brother Petro and Tres, who really couldn't care less.
And Caterina Sforza for Abel (maybe Tres for Caterina).
Ion Fortuna and the Pope, for Esther Blanchett.
Vampire Monarch: Empress Augusta Vradica the First is the leader of the Methuselah vampires of "The New Human Empire". In reality, she is the childlike Seth Nightroad, a Crusnik Vampire and is Really 700 Years Old.
