History YMMV / BrynhildrInTheDarkness

* AndThereWasMuchRejoicing: The end of chapter 157. Things looked bad for Kuroha for a while, but then.. oh sweet, sweet justice.
* BaseBreaker: Kazumi. While some fans like her straightforwardness and ShamelessFanserviceGirl attitude with Murakami, others find her JerkAss and DoubleStandardAbuseFemaleOnMale tendencies to be unpleasant. Her tendency [[DoubleStandardRapeFemaleOnFemale to molest the other female characters]] (even after being begged to stop by a then-immobile Kana in one such situation), as well as her character derailment into a one-note character only interested in sleeping with Ryouta, doesn't help.

* TheyChangedItNowItSucks: The reaction of multiple viewers to the removal of the Skadi Arc in the anime and the resultant changes to the Valkyria Arc.
* JustForFun/XMeetsY: ''Manga/ElfenLied'' meets ''Anime/NeonGenesisEvangelion'' but with the Judeo-Christian elements replaced with Myth/NorseMythology.

** Machina's explanation of Vingulf's motivations is filled with this. As if wiping out all life on Earth wasn't horrific enough, the fact that Vingulf, as a whole, and he, in particular believes, wholeheartedly, that Sorcerians are completely immune to Granii's effects, despite the fact that Vingulf's founder discovered alien ''corpses'' in a "manmade" artificial construct which is evidence that begs to differ. In addition, the self-proclaimed "Adam" is piss-poor father material, a DomesticAbuser at best, a murderous thug prone to OffingTheOffspring, at worst. [[{{Hypocrite}} and he calls ''humanity'' a failure.]] Not to mention that the "Eve" is merely a host to an alien parasite that could hatch at any time, with little to no warning, and, is dependent on a "medicine" that Makina has shown neither the ability nor the knowledge to produce or procure, and those that do would all be dead if Vingulf's plan succeeds.

* MoralEventHorizon: While many of the characters do absolutely despicable things, most of them tend to have good reason. Vingulf's agents and witches are motivated by threats to their own lives. Valkyria was DrivenToMadness. Ichijiku was ultimately trying to revive his sister, and understand the truth about life and death (why a corpse, even if all the parts are intact can't be revived). Makina has no such excuse or motivation. While his killing of the US president can be excused, in universe, as protecting the {{Masquerade}}, the fact that he immediately, of his own volition, teleports to Kuroha, breaks her arm when she, out of fear for her well being, refuses to go with him, decapitates Ryota when the latter simply asks "Why" and attacks Kana with deadly force, bisecting Mina in the process simply for showing up at the scene is a series of actions that he can not come back from, [[ForTheEvulz not that he even wants to.]]
* PlayerPunch: The fan base has taken Mina's permanent death hard. The fans will not be happy until Makina dies gruesomely, preferably screaming.

* TheScrappy: Takaya, whose treatment of Hatsuna goes far past comedic territory into genuine creepiness.
** Makina has happily thrown himself onto the scrap heap as well for his actions in chapter 152, 153, and 154. While there have been no complaints regarding his killing of the US president, the completely needless murder of Mina, and his utterly horrific IHaveYouNowMyPretty treatment of Kuroha taken UpToEleven has got the vast majority of the fanbase screaming for his blood, and they don't care who does it or how.

** Chapter 163 reveals that "witches" are girls that Vingulf has reconstructed from the corpses of young girls. This means that every single one of the children kidnapped on behalf of Vingulf is long dead, and an impostor, programmed with her memories is walking around, completely unaware in her place. Worse, those girls are all undergoing horrifically abusive "experiments" purely for the sake of "slaying the gods" which may well mean the end of all life on earth.

* CompleteMonster:
** Onodera's behavior is nothing but odious even by Vingulf standards. Her "researcher" subordinates are terrified that she will kill them at the slightest breach of protocol, such as failing to say "good morning" to her. She routinely takes witches and puts them through hell [[ForTheEvulz just because she can.]] She doesn't bother to hide her disdain of humanity as a whole, and after Makina's death, she uses magic on Neko when the latter was not even remotely a threat, planning to kill her when Hrist awakens.
** Makina's personality is so despicable that Onodera of all people calls him "rotten" and she can do so without being hypocritical.

** The second opening "Virtue and Vice" might be unfitting and the vocals are weird, but it's an awesome song by its own right. And did we mention that it was sung by '''''[[Music/FearAndLoathingInLasVegas FEAR, AND LOATHING IN LAS VEGAS?]]'''''.

** The second opening "Virtue and Vice" might be unfitting and the vocals are weird, but it's an awesome song by its own right, especially for the listeners who like ''Manga/DeathNote'''s "[[Music/MaximumTheHormone What's up people?!]]"

** Takaya, especially after allying with the heroes. He's a total BadassNormal, is a great [[BashBrothers Bash Brother]] to Ryouta, and his relationship with Hatsuna is both heartwarming and hilarious.

* EnsembleDarkhorse: [[MadScientist Kogorou]]. He seems almost universally well-received by the fandom, who consider him [[BadassBookworm badass]], [[CrazyAwesome Crazy Awesome]], and [[HotScientist attractive]]. It also helps that he's actively helping Ryouta as much as possible, rather than being a total JerkAss who's only interested in himself.
