* AlternativeCharacterInterpretation
* BrokenBase: Pre-Aramary and Post-Aramary fanatics.
* CreatorWorship: Fans have taken to calling Revo "his majesty" and pledging their allegiance to him after every concert. Revo just [[AscendedFanon decided to roll with it]].
* CrowningMusicOfAwesome: Most of the Moira album. But in particular, tracks 13 and 14.
* EpilepticTrees
* FanNickname:
** Heika/His Majesty: [[CreatorWorship Revo]]
** Tettere: The Princes from ''Märchen''
** Idoko: The Well Girl from "Sei To Shi Wo Wakatsu Kyoukai No Furuido", due to a popular theory that she's Idolfried Ehrenberg's daughter.
** Thanako: The insomniac girl from the album ''Thanatos''
** Lost-ko: The winged girl on the cover of ''Lost''
** Buranko: The Swing Girl from "Kuroki Okami No Yado"
** Aohigeko: The wife of Bluebeard from "Aoki Hakushaku no Shiro"
* FreudWasRight: As long as there is a hole, Bluebeard will pierce it with his Longinus.
* FridgeHorror: "Sei To Shi Wo Wakatsu Kyoukai No Furuido" is a bright, rockish song that really stands out compared to the rest of the album. Even the contents of the song wasn't dark or creepy(there were no deaths or bloodshed, for one). However, during the live concert, the bonus track "Kuroki Shi no Shinkou:" (read:"[[ExactlyWhatItSaysOnTheTin The March of the Black Death]]") was played before and after the song. Then you realize the very real possibility of the 'pitch' that the stepmother's daughter brought back being the black death bacteria, thus contributing significantly to the spread of the black death. Granted, this is only one interpretation of it, albeit an uncomfortably plausible one.
** In the Live DVD, the silhouette of a rat was shown at the end of the song which more or less confirms the suspicion.
** Ever seen a picture of someone with the black death? Screw bacteria, the girl wasn't covered in pitch, she was covered in the blackened dead flesh the bubonic plague causes...
** That's a [[RevengeBeforeReason really dumb revenge]], if so, though. What would give Well Girl immunity to the plague once exposed to it? This revenge may well have laid out the seeds of her second death.
*** She is covered in gold; if that was meant literally, she might be okay...
* MemeticBystander: Idolfried Ehrenberg has exactly two lines in Märchen, neither of which have anything to do with the plot. Fans have nonetheless constructed an entire backstory for him[[note]]He's the father of the girl from "Sei To Shi Wo Wakatsu Kyoukai No Furuido". He fell down the very same well that März did, and is the entity that März fused with to become Märchen.[[/note]], which may or may not be exactly what was intended.
* MemeticMutation: Thanks to NicoNicoDouga and Youtube, [[Manga/AttackOnTitan "Guren no Yumiya"]] is now [[http://knowyourmeme.com/memes/attack-on-titan-opening-credits-parodies anime's answer to Guile's Theme.]]
* MemeticSexGod: Idolfried Ehrenberg. Just look at that man. Soft, golden locks, sassy pirate attitude. He's everything you could ever want.
* LauncherOfAThousandShips: Märchen seems to be teetering dangerously close to this. Within a month of the single's release, people were shipping him with Elise, Elisabeth, März, Hiver Laurant and the PV dancers to boot.
* {{Moe}}: Pico Magic
* NightmareFuel: In Elysion, Elise in the official music video for the first track is a really [[CreepyDoll scary doll]].
** The [[http://sh-whitecrow.com/wiki/images/1/13/EliKumiUra.jpg illustration]] on the back cover of ''Elysion ~Rakuen Gensō Monogatari Kumikyoku~''. Like the front cover, it depicts Abyss standing behind El, with the five girls from the Abyss tracks standing in a row behind them. However, in this version of the image, Abyss has glowing red eyes and a SlasherSmile, El is smiling eerily and her dress appears to be splattered with blood, and there are depictions of the murders that the five girls committed in the background.
** In "Garasu no Hitsugi de Nemuru Himegimi", Snow White's sadistic joy as she watches her stepmother's CruelAndUnusualDeath.
** "Aoki Hakushaku no Shiro" in its entirety, but particularly the sequence which depicts the previous wives' murders.
** The WhamLine in "Yield": "Ah ... but isn't that a [[spoiler: head]]?"
* TearJerker: In Roman, Etoile's story. It's very likely that it will make you cry or at least shed some tears.
** In Moira, track 12. Dear goodness, track 12.
*** The way Revo performed that scream was heartrending.
* TheyChangedItNowItSucks: Again, Aramary. And every time a new CD is released.
* ToyShip: in Ido e Itaru Mori e Itaru Ido.
* UnfortunateImplications[=/=]ValuesDissonance: The FridgeHorror above from Marchen. TheBlackDeath doesn't actually come from wells. It comes from fleas on rats (presumably the reason they showed a silhouette of a rat in the live DVD). However, it was actually thought at the time of TheBlackDeath that it did, in fact, come from the poisoning of well water. The culprits who supposedly poisoned said well water? [[OnceAcceptableTargets The Jews]]. Caused a lot of deadly pogroms. You can probably hazard a guess that a song from the US (where there are more Jews) would have avoided that.
** The song "Tasogare no Savant" is also very difficult to discuss with an American without provoking an argument. Japan does not have nearly as strong a Christian or feminist presence as the US does, so while in Japan, the woman deciding whether or not to bear her child is simply an interesting mechanic through which to discuss the meaning and value of life, an American discussing it would inevitably wind up bogged down in the eternal abortion debate in the US, with many feminists taking issue with the fact that the woman asks the old man for advice on whether or not to keep the child.
