History VisualNovel / DiesIrae

* MassHypnosis: In order to make sure that the students are going to the school where one of the Swastika's are even with everything going on, they are all put under a spell that compels them to go. The name of the chapter where this happens? [[Literature/ThePiedPiperOfHamelin The Pied Piper]].

* MythologyGag: Ren has a poster for ''Paradise Lost'' in his bedroom, one of Light's earlier novels.

** GodInHumanForm: [[spoiler: Karl Kraft and Caggliostro are this for Mercurius, essentially little more than images of him that he interacts with the world that exists in him through.]]

* LifeDeathJuxtaposition: Marie was born under the guillotine as her father volunteered to carry out the execution of its latest victim.

* ThreeDEffectsTwoDCartoon: While the novel uses 2D art, there are two exceptions, namely when Eleonore and Schreiber summon their respective Ahnenerbe they are clearly using 3D animation.

A WhatIf sequel that acts as a HappyEndingOverride for one of the game's endings, ''VisualNovel/KajiriKamuiKagura'' was released in 2011. A prequel about Wilhelm Ehrenburg, ''Dies irae ~Interview with Kaziklu Bey~'' was released in 2016, the later of which was translated and released to English speaking fans in early 2019.

!!Tropes associated with ''Interview with Kaziklu Bey'':
* AfterActionPatchup: Wilhelm ended up quite battered and bruised after his battle with Machina and Schreiber resulting in Claudia patching him up after he returns to their hideout despite him not really needing it due to his HealingFactor.
* ArcWords: "Kiss in the Dark". A phrase the keeps having an overlying importance to the plot.
* ChekhovsGun: [[spoiler:The blood that Claudia liked from Wilhelm ends up coming back in a big way when it proves to be his key to victory in the climatic battle with Methuselah]].
* CombatBreakdown: [[spoiler:The battle against Methuselah at the start could best be described as an all out war with the whole of the L.D.O. involved fighting to the best of their abilities. It ends up concluding with Wilhelm and Ludwig, both at deaths doorstep, beating the living daylights out of each other with nothing but [[GoodOldFisticuffs their bare fists]]]].
* DiabolusExMachina: [[spoiler:Methuselah is defeated. Wilhelm expresses his love for Claudia. Claudia expresses hers. Cue her rosary turning out to be an Ahnenerbe that allowed for the activation of her Beri'ah that burns everything in range and uses her soul as fuel]].
* DownerEnding: [[spoiler:At the end of it all, Claudia dies while Wilhelm was never able to claim her soul. Wilhelm himself lost part of his soul due to using it in his Creation Figment. In the end, he can't help but bitterly laugh at the absolute joke this whole thing turned into and at the fact that Mercurius was correct from the start]].
* DroneOfDread: When Wilhelm gets trapped in some sort of darkness that forced him to witness Beatrice's and Lisa's darkest secrets, only a constant drone can be heard instead of music.
* EntertaininglyWrong: Wilhelm and Eleonore both hypothesize Ludwig's true goals [[spoiler: possibly along the lines of usurping Reinhard and luring everyone into a false sense of security until he strikes.]] Beatrice, on the other hand, thinks Ludwig is trying to go after Claudia in some sort of bizarre love triangle between him, Wilhelm, and Claudia. [[spoiler:Turns out she's right on the money, and Methuselah has no intentions of going after the LDO at all.]]
* HumansAreBastards: Human souls makes for extremely powerful fuel for magicians, however, no one in their right mind would use them as humans inherent greedy and vicious nature makes using them extremely dangerous and is viewed as downright suicidal.
* LeaveNoWitnesses: After Ludwig incapacitates a group of Soviet soldiers, Wilhelm notes that they can't leave them alive and proceeds to kill them by crushing their heads. Just as he is about to crush the last one however, Lisa makes him realize that the others never intended to let them live in the first place, they just didn't want to do it in front of Claudia.
* TheLostWoods: Katyn forest, the place where the Soviets executed over 22000 [=PoW=]'s and where their spirits now linger.
* MagicVersusScience: Mentioned as part of the backstory. In the past, magicians used to be dime a dozen as there wasn't much need for magic to be all that extravagant. But as science advanced, magic struggled to keep up and it became harder and harder for it to achieve the same things that technology could do in much simpler ways. By the time the story takes place in 1944, magicians are considered almost extinct with only three known true magicians known to exist, [[Creator/AleisterCrowley Crowley]], Rusalka and Mercurius. According to Mercurius however, the real reason the magic's influence weakened was due to the god of the world growing older and weaker, and thus, things that used to be easy became a lot harder to achieve without technology.
* MoodWhiplash: Lisa is going through a rather somber description of their mission in Katyn forest and the nature of human souls, and then all of a sudden Claudia butts in proclaiming that she needs to use the "[[PottyEmergency facilities]]". Everyone was left speechless by the sudden turn of the mood.
* NotWhatItLooksLike: Early on, Rusulka and Beatrice walk in on Wilhelm and Cladiua as the later is about to help her with her bandages. Both end up misunderstanding what is going on. He pretty much tells Dinah that is was pretty stupid and that she should just ignore that part. He does manage to explain to them though.
* {{Prequel}}: The story is framed as an interview starting some time before the events of the main Dies Irae plot line with the bulk of the narrative being Wilhelm recounting his past, providing background information of not only him, but the rest of the Obsidian Round Table as well.
* SavedByCanon: Seeing as this is a prequel to the original Dies Irae starring the members of the LDO, it's easy to guess that [[spoiler:nobody but Claudia and Ludvig]] ends up dying.
* ShootTheShaggyDog: [[spoiler:In the end, Wilhelm fails to break out of his curse of always losing whatever he chases with Claudia dying without him being able to absorb her, on top of losing a part of his soul, namely the part of him that loved Claudia]].
* StrangeMindsThinkAlike: Turns out Wilhelm get's along surprisingly well with Eleonore. This mostly stems from their similar views on Reinhard despite being so ideologically different otherwise.
* TeethClenchedTeamwork: On the mission to Katyn forest, Wilhelm has to work closely together with Beatrice. To say that those two go together like oil and water would be an understatement.
* UniverseCompendium: Downplayed, the novel provides a simple glossary to help readers get up to speed on some of the terminology and how the magic system functions, but it is not all-encompassing.
* VillainEpisode: A side story focusing on one of the villains of the main novel.
* VillainsOutShopping: The members of the L.D.O. still has to get food and the like in order to not waste energy which in turn results in Claudia dragging Wilhelm all across the local market.

* ConspicuousCG
** While the novel uses 2D art, there are two exceptions, namely when Eleonore and Schreiber summon their respective Ahnenerbe they are clearly using 3D animation.
** The anime adaptation makes liberal use of CG, something that is often painfully obvious.

* SoulPower: The basis of Die Ewigkeit allows one to use souls as a means of both defense and offense. Defensively it allows the user to resit standard weaponry as most weapons can only take one life while they have thousands in stock, hence why only weapons of mass destruction can really hurt them as they are capable of killing thousands. Offensively it acts on a similar principle, taking multiple lives in a single strike. Due to this, soul count and mass is quite important.

A visual novel by the company Light ([[JustForFun/IThoughtItMeant no]], [[Manga/DeathNote not that Light]]) and the second game in the ''VisualNovel/ShinzaBanshoSeries'' that has had a colorful release history.

In May of 1945, as the Red Army storms Berlin, a group of Nazi officers use the resulting bloodshed to complete a dark ritual to summon the Longinus Dreizehn Orden[[note]]the Order of the 13 Lances[[/note]], superhuman harbingers of the world's demise. It wasn't known if the officers succeeded in their goal and the incident eventually faded into obscurity.

Sixty one years later, the Orden makes their appearance in Suwahara City. Despite Ren's desires for an ordinary life, he finds himself forced into a war against the Orden, drifting further away from what he once held dear. Like Shirou once said, "If you live in this town, you'll go mad sooner or later."

* TookALevelInBadass: Getting an Ahnenerbe seems to do this. Turning genuinely scary murderers and soldiers into super-powered {{Ghostapo}} members.

* NostalgicMusicbox: The track [[https://www.youtube.com/watch?v=Tjeo-JpBdnI Ewige Wiederkunft]], a track usually reserved for scenes of reminiscence, makes use of a music box to help sell the nostalgic feeling.
