While not as popular as Shoko x Haruto, Shoko x L-Elf, or Haruto x L-Elf, quite a few fans shipped Saki and Haruto in the first nine-and-a-half episodes of the 1st season. As soon as Episode10 finished airing, however, some fans started avoiding this ship like the plague...or at least until the next week's episode came around. And by season two, most have returned to this shipping due to later problems concerning the Shoko x Haruto shipping, and L-Elf gaining a much more popular alternative ship with Liesellote.
Same thing for the Shoko X L-Elf ship when it's displayed how ready L-Elf is to put a bullet through her head should she get in his way.
Shoko x Haruto took a major hit after she sold out the Valvrave pilots after The Reveal of their powers. Did not do wonders for her fans.
Angst? What Angst?: Raizo has absolutely no angst about the changes and odd powers he gets upon becoming a Magius. In fact, he views them as a bonus.
Same with Saki after Episode 10's ending. You'd expect her to be traumatized, but Haruto shows a much stronger reaction (granted, Saki DID know Haruto could lose his sense of reason, and possibly let it go because of that, but it's still a large stretch), and in Episode 13, when Haruto is having severe fits, she actually offers that they have sex to relieve him, though he refuses.
Ass Pull: The Valvrave absorbing memories from the pilot can be seen as this, because it was never foreshadowed in season 1 since Haruto never showed any visible signs of suffering amnesia. That said, in early-to-mid season two it was mentioned that Haruto's brain did start showing some deterioration, albeit at a much slower rate than Marie did, even before he had consciously lost any memories at all, so the process might have been too gradual for anyone to notice the effects at first.
After Episode 6, reactions to Saki resulted in this due to a sequence of rash and selfish actions she takes such as abandoning her humanity without a second thought, manipulating Haruto so that she could take over his body and use his fame to boost her own fame, and leaping into the fray of battle only to get cold feet when she faced opponents who weren't easily to defeat. The outcome of her first solo fight did not help this. Afterwards, fan reaction split between those who consider her The Scrappy for the previous mentioned actions, and those who actually enjoyed watching this development unfold throughout the episode and grew to like her newly discovered character even more.
The scene showing a Valvrave controlled Haruto raping Saki has many fans divided on whether that scene was appropriate or not. And the subsequent handling of the "morning after" and Haruto's marriage proposal is not going over well with people who expected a different treatment of the subject.
Ironically, season two pretty much ups her status to Ensemble Darkhorse as fans continue to feel bad for her for always getting screwed over in some way (imprisonment, embarrassment on national TV), and for her shipping with Haruto making a comeback.
Episode 21 pretty much splits Shoko's fanbase after selling out Haruto (and the other Valvrave pilots) and L-Elf to ARUS. Many former fans have reversed their positions declaring that she's crossed the Moral Event Horizon while her defenders argue that her actions were justified. During the final episodes, Shoko openly cried within Unit 1's cockpit once she learned that Haruto had renounced humanity for her sake. Unfortunately, she had to keep up appearances in public and didn't let Haruto go past the hangar when he came back to the shuttle. Shoko never had the chance to personally apologize to Haruto before his death, though he did at least learn about her real regretful feelings from Pino. Shoko was also shown to be sad upon learning about his death and reflecting about it aftewards. In the end, fans remain divided over how her actions should have been addressed and there is polarization concerning how she eventually became the next Valvrave pilot. Some see that as being disappointing, escaping from her responsibilities and going against Haruto's wishes of protecting her from the curse, while others see it precisely as Shoko's way of making up for her fears and distrust by assuming Haruto's role in a period where the curse is now seen as a blessing.
The second season got hit with this hard after the airing of the last episode; split between those who thought it was a major improvement for toning down on the random craziness that drove viewership away throughout the first season, and its detractors who state that the second season was weaker because said craziness was what originally brought people back to continue watching the show.
The final episode has a split of its own. Either people are satisfied with the conclusion, or it was a rush-job leaving too much unanswered that a third season of material was needed. The resolution has been felt to be too forced as it ignored all the negative consequences of the characters' actions such as Haruto's death in favor of happy events. That's not even mentioning the lack of unresolved mysteries and the epilogue scene.
The death of Haruto also got this. While some found the scene was well done, others saw it as unnecessary or just a cheap excuse to give the viewer a sad moment considering Marie had previously survived to losing all her memories once. Plus the fact it his story sad as he never made up with Shoko, achieved his dreams of coexisting and his biggest fear of Shoko being cursed became true.
Crosses the Line Twice: The show goes so far in its ridiculousness and absurdity that it slides right back to understandable.
Designated Hero: L-Elf attempts to kill Haruto early in the series (as well as several innocent people) and later shoots Marie in the face just to keep her from distracting Haruto. Everytime a member from the team is in problems, L-Elf won't care and in early season 2 it requires everybody's voice to convince him to save a young girl. It's amazing Haruto ends up becoming his friend.
Cain as of Episodes 11 and 12 has become one of the most popular characters in the series particularly for being the first person to genuinely outsmart L-Elf in combat. The ongoing mystery regarding what the hell his character is, which turned out to be a fatherly ultra-Badass Normal who was possessed by a Magius, also helped.
Senator "Moses" Figaro has become this almost entirely based on his famous line "Call me Moses, for I am about to part this sea of students before your very eyes?". How does he accomplish this feat? WITH GUNS!
If the Valvrave can turn Haruto into a vampire, what else is that mecha capable of doing to its pilot? It turns him into a body snatcher! Also, if it doesn't accept the pilot, the robot makes the person explode.
Appparently, 'possess her designated pilot and use his body to attack people and rape innocent women.
The entire finale is one big Broken Aesop: While Liselotte wanted Magius and humans to coexist, L-elf's actions caused a Magius genocide. In the end Shoko became Valvrave 01's pilot. What was Haruto's biggest fear? Having Shoko pilot it!
Not quite a Magius xenocide as it seems to be mostly the Council that takes the brunt of it, and we can assume that there are far more Magius around given that the Council is 'merely' the 101 most powerful and influential.
There's also the scene where Haruto goes into vampire-mode and attacks Takahi; Saki kicks him back to his senses, and he brushes off the incident by claiming she was so sexy he couldn't control himself. Aneurysmed, as above, by the rape scene.
The students' final solution to holding off ARUS and Dorssia (independence now!) is one thing, but then you have the Valvrave seperating their part of the country much like an old cartoon with Bugs Bunny, a saw and Florida.
Haruto and L-Elf in spades. In the first scene we have L-Elf's aparent obsession with getting Haruto to serve as his right hand. At the start of the second season, we have L-Elf agreeing to become Haruto's main source of runes whenever he needs to bite someone, L-Elf's promise to "use him until he has nothing left" which refers to how Haruto will eventually run out of runes and become an empty shell, but could also be taken a very different way, and the ending includes a sequence in which they're both free-falling and attempting to grab hold of each other. There's also episode 22's infamous "Waifu Fight," the "promise" and the fact L-Elf's main love interest has kicked the bucket, and how the prince from the future seems to have L-Elf's hair and Haruto's eyes.
A-drei and L-elf is quite popular in the Japanese probably due to their relationship which becomes Foe Yay across the story.
Idiot Ball: Just about everyone grabbed it in Episode 21 to various degrees.
It's not hard to lose respect for the Valvrave's OS after Episode 10. After all, the machine possessed Haruto and ultimately had him rape Saki, a girl who already went through enough in her life and, until that episode, was pining for the guy.
Figaro crosses it when he tries to abandon JIOR with Haruto captive.
Multiple members of Dorssia Empire cross it almost everytime their appear, especially when they use forbidden poison gas against unarmed students in Episode 12.
L-Elf gets his moment of crossing when he shoots Marie just because she was delaying the mission and was about to discover the secret of the Kamitsuki.
The ARUS president ordering the massacre of students upon the reveal of Haruto and the others being Magius.
Shoko selling out Haruto and L-Elf to ARUS partly because of the reveal that he was a Kamitsuki and partly because he forgot their childhood promise.
Never Live It Down: The infamous scene involving Possessed!Haruto's sexual assault on Saki from Episode 10 is so frequently referenced by the fandom that it probably will not be forgotten for at least a couple of years.
Plot Tumor: The flashforwards have gotten really negative response for not adding anything to the plot or even explaining what exactly is the setting. The finale's most common criticism is its rushed ending which jumped from a sad scene to the future completely skipping the characters' reaction to the Magius' revelation, the JIOR students accepting their mistake when selling out the Valvrave pilot or the reactions people had to Haruto's death. The fact the identity of the Prince was also never explained.
Q-Vier is one of the least liked characters, no doubt thanks to his lack of any sort of Hidden Depths compared to the other Karlstein Graduates and his direct and/or indirect murders of Yamada, Aina, and Liselotte.
Episode 21 turn most of New JIOR's students who consider the Valvrave pilots monsters to the point of selling out to ARUS with Shoko kind of getting rescued in the finale while Iori Kitagawa never left the heap. This mainly due to the fact they put Revenge Before Reason and became Karma Houdini who never made up for their actions.
Second Season Downfall: More of a first season downfall, but Word of God once confirmed that they wanted this series to go on for many seasons. However, due to how controversial the first season was, the series took a massive hit rating-wise, and had to conclude much earlier than was originally planned when the second season came around.
Did you ship Haruto and Shoko? In season one, Haruto is convinced that his vampiric powers mean that they can never be together and fears getting close to her; there's also Shoko's betrayal of him in season two.
Did you ship Haruto and Saki? Pino takes over Haruto's body and uses it to rape Saki, causing people to abandon the ship en masse. The surprising/sad thing is that people have actually been returning to this ship in season two due to the previous mentioned problems regarding the Haruto and Shoko shipping.
Haruto and Aina? Aina is killed off almost immediately after we get a Ship Tease.
Ships That Pass in the Night: Despite the former being the arguable reason for her public execution, and that they don't really seem to have any sort of friendship with each other, A-Drei x Saki is surprisingly popular amongst some fans.
Snark Bait: Those that did not see the series as Camp tended to hate it, not unlike Code Geass and -to a lesser extent given its greater negativity- Guilty Crown.
People's impressions about this series change pretty often depending on the flow of events and the treatment of its different subject matters. While the first episode had a dark atmosphere, the following episodes kept a relatively light-hearted tone. Then Episode 7 came along and had someone Killed Off for Real, confusing some viewers about what the writers are trying to do.
There are fans who seem convinced that the writers aren't sure of what the writers are trying to do. Not that they seem to mind.
Many viewers were disappointed with the fact that Liesellote was killed so suddenly after all the build up for her introduction. Shippers actually appreciated for how she made L-Elf more likable and appeared in lots of fanarts.
Shoko got a lot of backlash as a result of her questionable actions in the second season. Most Fix Fics tend to completely change this.
X-Eins. As someone who finally learns the truth about Cain's secret and H-Neun's death, a majority of fans feel that he got the short end of the stick regarding screen-time/importance due to suddenly getting killed off in the series finale and not having any payoff for his character. At this point, he had every reason to hate Cain due to being seen as a heroic figure to X-Eins that turns out to be an Evil Mentor, and for being the cause of one of his companions (H-Neun) dying.
They Wasted a Perfectly Good Plot: After Episode 1, you might be thinking that the show, at least in the best case scenario, could be something like Bokurano meets Hellsingin aGundamsetting. But the idea of seeing a straightforward exploration of that potential was apparently ditched with the second episode, and the series puts more of an emphasis on the resulting mess of Narmtastic anime cliches and plot twists derived from that mix of elements.
Haruto, dear? The on switch was directly in front of you. Though considering what it was asking, normal people wouldn't press that button unless as a last resort. Which it was. However, let's face it. Everyone except possibly L-Elf, Cain, and X-Eins, have their share of Too Dumb to Live moments in this show. (And L-Elf is dumb in other ways).
Vanilla Protagonist: Haruto is a fairly normal character without any outstanding quirks compare to other characters.
To be fair, one important detail is being totally overlooked here. The formal excuse for the massacre is fairly dumb and contradictory on paper, but that's all it is: a cheap excuse used as cover-up. The real decision doesn't come from "humanity" suddenly wanting to eliminate "monsters" at all. The Magius, who as we know are also monsters, directly control Dorssia and the President of ARUS is also connected to them. He's the last person who would be surprised by the existence of monsters, but also is the first person to order the massacre. The whole thing wasn't a spontaneous anti-immortal backlash but a trap to bring down the Module. Whatever the public at large would think seems to be irrelevant. That said, the human soldiers involved in the operation probably aren't very clever either.
The final episode just marks Iori as the ultimate one. What Iori? They said Haruto used your dad? Then that must mean he is a bad person? Wait, you have no proof that actually happened? Duuuuuuuuuh....
What Do You Mean, It Wasn't Made on Drugs?: Half of the fandom believes it as a result of several sci-fi elements and actions including "space vampires", mechas that make you immortal, body swapping, most of the things Shoko says and the origin story of the so called "space vampires"
Haruto. The series starts with him becoming a Magius, in attempt to avenge Shoko. Then, one by one, several of his friends and classmates undergo the same transformation, despite his desire to be the only one so cursed. And then his urge to attack people culminates in VVV-tan taking control of his mind and making him rape Saki, which he most assuredly had no desire to do.
Mixed reactions from viewers aside, Saki easily qualifies as this. Already coming from a family of abusive parents, she's trying her hardest to leave her past behind her. Things get a whole lot worse for the poor girl in Episode 10, when Haruto, a boy she's been interested in for much of the first season, rapes her. Regardless of your position on Saki, no one should have to suffer the horror of being raped. NO ONE. And while there's a further Broken Base regarding that last part due to her extremely downplayed reaction to what happened, that kind of reaction does indeed happen in Real Life to some rape victims, especially those with a long history of abuse in their lives (which Saki qualifies), or who come from cultures where rape is seldom seen as "wrong." Considering how the Jior students reacted to Akira's back story of being bullied and mentioned that "she brought it on herself," Saki may well have both. Top all that off with being stabbed through the heart by Cain in order to out the Valvrave pilots as immortal beings in the second season, and it sure sucks to be Saki.
Shoko gets quite a few woobie points after having to decide between giving up the Valvraves in order to save her father and residents of module 77's families (but abandoning the rest of Jior), or letting him die so they can make it to the moon and continue to fight. In the end, he's killed when Haruto wipes out the much of the Dorssian fleets, unaware of how Shoko's father was on one of the them. Nobody blamed her when she broke down sobbing.
Akira warrants a mention as well, mainly due to her severe social anxiety, which was brought on by some horrendous past bullying. Later, episode 14 reveals that the bullying came about as a result of being shamed and mistreated by everyone because she was guilty of hacking into the network of a prestigious school in order to obtain the questions for its entrance exam. It was a good-intentioned, but misguided attempt to help her brother gain passage into said school, as he was severely exhausted and nearing a mental breakdown from studying for the test, all thanks to the extreme pressure their parents were putting on him to get into the best school possible. The fact Satomi refused to acknowledge Akira had done this for his sake broke her, and then how he kept turning a blind eye to her bullying despite repeatedly reaching out to him for his help broke her even more.
Jerkass Woobie: L-Elf, a cold and ruthlessly pragmatic soldier who will not hesitate to kill whoever stands in his way and isn't useful to him, while at the same time manipulating those he has a use for and using them as pawns. A war prisoner from a country conquered by Dorssia, his life was saved by Princess Lieselotte, which sparked his Undying Loyalty towards her. As she was the only person who ever treated his with kindness, L-Elf made it his life mission to save her from her plight and start a revolution of Dorssia in her name. In the end, even with all his genius, his plans come to nothing as Lieselotte - revealed to be a Magius inhabiting her body - does an Heroic Sacrifice to save him and the Valvrave pilots, and he later ends up also losing Haruto, the only person he could ever call a friend.
