History YMMV / ValkyrieDriveMermaid

* CrowningMomentOfAwesome: Mirei saving Mamori from being [[RapeAsDrama raped]] at the end of episode 2, by [[DynamicEntry jumping]] through a stain glass window, [[TheStoic wordlessly]] delivering a kick to the would-be rapist's gut, and driving with Mamori in possibly the most awesome kiss scene yet. Then it's followed by Mirei escaping the academy, only stopping to tell Agnsi, and Charlotte ''she can't bother fighting them, she promised'' (with the implication it would have been a CurbStompBattle on her part). The entire scene is accompanied by an [[AwesomeMusic kickass]] instrumental piece.
* CrowningMomentOfHeartwarming: Mamori finally accepting Mirei as "her prince" in episode 2 after being rescued from the AttemptedRape, puckering up, and giving herself to Mirei willingly is truly a sight for sore eyes. Not to be outdone, Mirei goes and tops her in the very next scene by honoring her wishes to avoid violence by simply jumping past Agnsi (after swatting the wires away) calmly stating "sorry, I can't fight you. I promised." At that point, Mirei has proven that she ''earned the right to be Mamori's partner and wield her as an Arm.''
* CrowningMusicOfAwesome: The anime's opening, ''Overdrive''.

* FetishFuel: Breasts are the main fetish fuel and the creators make sure that they are detailed, especially their ''nipples''. Also, the female cast has various body proportions which makes some of them [[EnsembleDarkhorse win over the fans]]. Notable standouts include [[{{Pettanko}} Meifon]] and [[BigBeautifulWoman Torino]].

* IKnewIt: A lot of fans have assumed that Akira is also a female due to his androgynous appearance and his feminine voice months before the anime aired. [[spoiler:And they were right.]]

* ViewerGenderConfusion: Despite Akira's profile stating that he's the only male on the island, a lot of viewers assumed he is also female. This is most likely due to his androgynous appearance. However, strangely enough, his three sizes (Bust/waist/hip measurements) are given in the official profile, which are not normally precised for male characters, indicating possible foreshadowing of Akira's true gender.

* Mamori. She gets taken from her home and parents and sent to an island, by complete strangers, in broad daylight right in her school! Utterly confused by her situation, she then gets attacked with a powerful firearm for no real reason. The one person who comes to her rescue, Mirei, gropes and fondles her, [[NightmareFuel causing her to experience black outs. It isn't until Kazumi shows her an explicit video of herself that she learns why.]] Immediately after that, with no time to recover, she gets put into a wedding dress, handed off to Nukui, again a complete stranger, and almost gets raped. There's also a flashback of her being bullied at her old school because rather than being quarantined immediately, apparently her medical results about an irregularity are made public.

* Mirei. The more we gleam about her backstory, the more horrific it seems. While the chronology is not yet clear, as a young teen (she's 15 now), she was in a war zone, fighting for her life against a rather sizable army of HumongousMecha, and winning. She only lost because she hesitated to kill a terrified soldier who collapsed to his knees in front of her, after she ripped apart the mecha he was riding like a soup can, and she got hit with a significant barrage of missiles from behind. This not only left her grievously wounded and unable to resist, but separated her from her blue-haired partner whom she clearly treasured. She suffered gang rape, or worse, or both. Again, not stated if before or after the battle, was also shipped to Mermaid via missile, and is now the target of Welter, especially Charlotte, who will stop at nothing to beat her down and brutalize her for actually daring to fight back and win.

* Mamori. She gets taken from her home and parents and sent to an island, by complete strangers, in broad daylight right in her school! Utterly confused by her situation, she then gets attacked with a powerful firearm for no real reason. The one person who comes to her rescue, Mirei, gropes and fondles her, and then she passes out. Then later, she gets forced into a partnership and almost gets raped. There's also a flashback of her being bullied at her old school because rather than being quarantined immediately, her medical results about an irregularity are made public.

* TheWoobie: Mamori. She gets taken from her home and parents and sent to an island. Utterly confuse of her situation, she then gets attack for no real reason. Then later, she gets force in a partnership and almost gets rape. There's also a flashback of her being bully at her old school.

* EnsembleDarkhorse: A lot of them but Meifon gets the most treatment of this, especially for {{Pettanko}} fans.

* CrowningMomentOfHeartwarming: Mamori finally accepting Mirei as "her prince" in episode 2 after being rescued from the AttemptedRape, puckering up, and giving herself to Mirei freely, openly, willingly and completely without hesitation is truly a sight for sore eyes.
