* BizarroEpisode:
** The BonusEpisode episode for the anime, which takes the main cast into the ''Pink'' Night, and perverts their powers in various ways.
** Kakeru now has {{x-ray vision}} that can see through clothing: regardless of gender.
** When Yukiko removes her glasses, she acts like she's on an aphrodisiac, including kissing Yuka.
** Takahisa now has [[MakingASplash water powers]]. He can shoot a tiny stream of water from his finger.
** Misuzu summons ''vibrators''.
** The Larva are now {{Ridiculously Cute Critter}}s.
** Kururi can speak, but nobody wants her to. Everything she says is [[SoundEffectBleep bleeped]], everything she draws is [[{{Pixellation}} pixellated]].
** The Black Knights are now the Pink Knights, an all-pink {{sentai}} team (with [[InTheNameOfTheMoon roll call]]) who die because of ''their own dramatic explosion''.
** Liselotte is now Avaritia's dominatrix.
** Then it becomes a HotSpringsEpisode, revealing that Yuka's AntiMagic has turned into TheNudifier. It also [[GenderBender turns Kakeru and Takahisa into girls]].
* FanPreferredCouple:
** Kakeru with Misuzu.
*** Kakeru with Shiori too in the game.
** Takahisa with Yukiko
* FoeYay:
** Between Kakeru and Liselotte. In a SS, he even had a H-scene with her. There is also between Avaritia and Liselotte in the OVA.
** Kanae and Shuu in Crossover. She has apparently a kind of attraction toward him.
** And a bit between Misao and Scholastica too. According to the Phantasmagoria spell, it seemed Misao was actually the person who Scholastica cared the most about. And Misao lost it when [[spoiler: Scholastica is killed]].
* HoYay: Between Georgius and Samson in Before Story arc in Resona forma even if [[spoiler: Samson actually loved Misao ]].
* LesYay:
** Yukiko enjoys to touch the breasts of the others girls. Kukuri and Yuka are even confused about it. The OVA had Yukiko nibbling on Yuka's ear and giving her a deep kiss. Yuka's facial expression? It [[LuminescentBlush seemed]] like she liked it! She is also often showed in LesYay position with others girls 11eyes in official arts.
** Between Mio and Shione in the Crossover story. Mio wants to protect Shione more than anything and would like her happiness.
* {{Moe}}: Kukuri
* MoralEventHorizon:
** The anime version of Yuka crosses it when she tries to kill Misuzu with a razor blade in her tea, which doesn't happen in the original game.
** In Before story it implied Invidia crossed the line as [[spoiler:she killed a man who had a different belief of her and even if she was sent in mission by Index, it didn't prevent her to take delight to kill him.]] Without forgetting she also [[spoiler:tried to kill Misao for nearly the same reason.]]
* RescuedFromtheScrappyHeap: Yuka Minase to a certain degree for her anime portrayal (depending on who you ask). The middle episodes brought to light her Bitch in Sheep's Clothing persona, but episode 12 attempted to calm the past viewer hate with a TearJerker flashback that showed the childhood memories between Kakeru and Yuka.
* TearJerker:
** When Yukiko killed Takahisa, as much in the game than in the anime.
** It kinda applied to the episode 12, where Kakeru reminisced his past with Yuka which shows how she always supported him during their childhood and after the death of Kukuri. However, it could be subverted as Yuka had been showed as a Bitch in Sheep's Clothing during all the half of the anime.
** Lisette's past without any doubt.
** If story. The moment where Verard saved Lisette,[[spoiler: then died]] after having fought 90,000 crusaders for her safety will make you cry like a baby. Especially the scene where Lisette confessed her love and answered his name, Verard [[spoiler:disappears and returns in his time before to be killed. He understood his death now has a meaning.]]
*** It's a lot sadder when you realized [[spoiler:that If Story is just a fictive story made for fans. So, this story didn't really happen and Verard didn't really save Lisette.]]
** Before Story without any doubts has a lot of TearJerker moment, as the story told the past of the Black Knights. If you played the original, you'll expect what's happened to them.
*** [[spoiler: Every deaths of the Black Knights will make you cry. Especially Irene's and Sebastianus's deaths when we understood that Irene was apparently pregnant, so their happy ending fell.]]
*** [[spoiler:Samson's death. Especially when we learnt that he loved Misao from the beginning and didn't hesitate to sacrifice himself for her safe.]]
*** [[spoiler: Even if Benedictus wasn't really a sympathetic character, you'll feel bad for him as it's the only moment where he actually cared and cried over someone, making him slowly Jerkass to JerkWithAHeartOfGold.]]
** Liselotte's defeat. Subverted in the anime.
* TheScrappy: Yuka Minase's portrayal in the anime compared to her game and manga counterparts ''really'' ups her {{Yandere}}, ClingyJealousGirl, and Bitch in Sheep's Clothing tendencies towards Kakeru; causing a lot of viewers to despise her as the anime went on. The low point was passing the MoralEventHorizon when she attempts murder by putting a razor-blade in Misuzu's tea in episode ten.
