YMMV / High School DD

This page contains unmarked spoilers for the first twelve volumes. You Have Been Warned!
  • Alternative Character Interpretation: Did Odin really abandon Rossweisse just because he got tired of her as his bodyguard, or because he felt Rossweisse deserved better but knew talking wouldn't work with her?
  • Anti-Climax Boss:
    • Even after being turned into a chimera, Kiba one shots Freed like nothing.
    • Kokabiel, the Big Bad of Volume 3, could be considered this as well due to the sudden curb-stomping he received from Vali as a means to hype up the latter's power.
    • Leonardo of the Hero Faction. He is established to have control of one of the most overpowered Longinus' known to exist... and yet, he suddenly loses off-screen, and ends up randomly becoming Shalba Beelzebub's brainwashed henchman.
    • The Old Satan Faction. Katerea Leviathan is quickly Impaled with Extreme Prejudice by Azazel with only a self-sacrificed (and easily replaced) arm to show for her efforts, Creuserey Asmodeus gets obliterated into dust by Sirzechs a few minutes after his introduction, and Shalba Beelzebub is curb-stomped by Issei twice, the first as a result of Juggernaut Drive and the second resulted in Issei's first kill (even Issei himself commented on how underwhelmingly weak he was), though Shalba manages a Mutual Kill through underhanded means.
  • Arc Fatigue:
    • The third season, BorN, is criticized by fans for distilling volumes 5 through 7, given the popularity of the anime series. The first half of the season is reordered to follow volumes 5 and 7, while the second half adapts volume 6 and adds an original ending. Fans did express frustration with Loki inflicting a curse on Rias and Issei.
    • For some, the vampire civil war, due to what appears to be Ichiei Ishibumi using it as a side-story just to introduce Rizevim Livan Lucifer as one of the Khaos Brigade's new leaders.
  • Ass Pull:
    • The Breast God appearing to help defeat Loki. To be fair though, it's even treated as one in-universe.
    • The relationship trauma Raynare caused to Issei is a major theme that Issei has to overcome in volume 10. However, despite being one of the most loved volumes amongst fans, it can come off feeling suddenly out-of-nowhere as there was absolutely no Foreshadowing in the prior volumes to show that Issei had been suffering in this regard. The anime actually sets this up better by showing glimpses of the trauma at the start of the third season, which was only just starting up the volume 5 content at that point.
    • Kiba achieving Blade Blacksmith's Balance Breaker even though it was never hinted until Volume 10 he had another Sacred Gear. It isn't possible to actually DEVELOP a second Sacred Gear you aren't born with.
  • Author's Saving Throw: After the BorN fiasco, Ichiei Ishibumi and Kadokawa wisely chose to play damage control. Ishibumi wrote EX and Kadokawa announced in late 2017 that Hero will adapt volumes 9 to 10; they switched the animation production studio to Passione.
  • Awesome Art: The quality that Miyama Zero puts into the Illustrations of the Novel are great, and are gorgeous to look at.
  • Base-Breaking Character:
    • In spite of being the most popular villain in the series, to say that Raynare is a divisive character is an understatement: one half says that Raynare is nothing more than a smug, coward villain who deserved her comeuppance by the hands of Rias, especially for killing Issei with no good reason. The other half, instead, says that the psychological damage Raynare inflicted to Issei made the series a lot more interesting, and also that she could have at least had some of her backstory expanded. And then there are those who whitewash her like she's Draco Malfoy.
    • Vali is also recipient of this: he is either one of the more badass characters in the series or an utterly obnoxious, overpowered Jerk with a Heart of Gold, with little middle ground.
    • Issei himself is one. A lot of fans of the series love him due to his Loveable Sex Maniac qualities and overall badass tendencies. However, many of his detractors dislike him because of those sex maniac qualities, viewing him as too perverted and annoying to be a decent protagonist. Not helping matters is Issei's status as a very blatant Escapist Character. One side doesn't mind that aspect of his character, while others feel like he takes the escapism too far.
    • The main heroine Rias is also one. Many enjoy her relationship with Issei (who he is most in love with) and the fanservice she provides, but some are annoyed by her selfishness over Issei and argue that her track record in battle is sub-optimal for the main heroine.
    • Among the girls of the harem, Asia and Koneko have the most naysayers. Both have relatively child-like proportions (though Koneko later gains the ability to age herself up), which can Squick some people out of the fanservice they provide or simply make it much less appealing than with the other girls.
      • Asia's supporters view her as a sweetheart and The Woobie who provides vital support to her team. Her detractors complain that she is generic and sickeningly sweet with an annoyingly high-pitched voice, often gets in the way of Issei's moments with Rias (whereas the other girls will compete for Issei's attention, Asia often simply cockblocked him outright), and has no fighting capabilities whatsoever.
      • Koneko's controversy, aside from her appearance, mostly comes down to her Pervert Revenge Mode toward Issei; it's either hilarious and reasonable to keep Issei's sex drive in check, or it's a complete killjoy.
  • Big-Lipped Alligator Moment:
    • Fafnir's cooking show in Volume 17 during what is supposed to be an intense battle between Issei and company against the forces of Qlippoth. Rias lampshades it as well. At the very least, it led to several Evil Dragon clones getting converted into protectors for Asia.
    • During the ninja side story (side stories already having a silly tone compared to the main story), Sirzechs pops out of nowhere as Satan Red, only to be dragged back by Grayfia just as quickly. The author laments in the afterword that his brief entrance was unnecessary.
  • Broken Base: Despite the DxD fanbase being surprisingly mature, there are some things that most fans don't heartily agree upon.
    • If there's one thing fans really can't agree on, it's the Gremory-Sitri Rating Game. Was it thoroughly justified that the Gremory team had a limiter working against them, thus giving them a real wake up call that just powering through everything isn't really all there is to it, or was it unfair to the Gremory team that they had a limiter on them when they couldn't show off what they could do now after their training? Or you're probably on the third faction and thought that the limiter made the Sitri team look weak, never mind Souna being able to adapt things on the fly because only the protagonist has the right to be a Combat Pragmatist, right? Part of the problem really is because Issei, the protagonist himself, gets taken out halfway through the game because of said limiter imposed when most series would have the protagonist be present all the way to the end.
    • Who is better? Rias or Akeno? Although almost all fans like both of them at the same time, let's just leave it at that. Some Take a Third Option and instead choose Asia... or Koneko which is, err, complicated.
    • The ever present Dub vs. Sub debate. Complicating the issue is that the dub is censored for simulcast note , but is full of Woolseyism.
    • The level of fanservice is a hot issue. DxD is well known for its heavy ecchi elements and its extremely perverted protagonist who's gotten several powerups through lust. Some enjoy enjoy the fanservice itself and how unapologetically over-the-top it is, while others criticize it for often messing up the tone (especially in the anime, which throws in gratuitous Clothing Damage even in serious moments like Asia dying from Raynare extracting her Sacred Gear) and find Issei impossible to take seriously.
    • The third season of the anime has garnered particular attention thanks to Tetsuya Yanagisawa altering the timing of some events from the novels against Ichiei Ishibumi and Takao Yoshioka's recommendations.
    • With the fourth season being produced by Passione this time around, Makoto Uno redesigned the characters to match the light novels. Was it for the better, or for the worst?
  • Complete Monster:
    • Freed Sellzen was an exorcist who worked for the Holy Church, but did not believe in God and only joined to fight monsters. When the church kicked him out, he was free to kill anyone he wanted whether they were monsters or humans, eventually becoming hired help for several of the series Big Bads. When he first appears, he murders one of Issei Hyodou's clients and tries to kill Issei himself, only to be stopped by Asia Argento. When Freed notices they met before, he tries to rape her in front of Issei, only to be stop when Rias and her peerage came, causing him to retreat, taking Asia with him. He later appears working for Raynare, but only when she offered to have sex with him, and quickly abandons her when she gets overpowered. He later appears under Kobakie's employment, during which time he commits more atrocities, ranging from nearly beating Irina to death, to taunting Rias's knight Kiba with the fact that his swords where created from the experiments that killed Kiba's friends, while the two were fighting. In his final appearance, he was captured by the Khaos Brigade and willingly became a chimera so that he could finally kill the heroes and even ate two of their knights to make sure he didn't lose. Psychotic and perverted to a fault, Freed Sellzen manages to give a new meaning to the term Light Is Not Good and become one of the heroes' most dangerous and disgusting foes.
    • Valper Galilei doesn't appear as threatening as most villains, but his actions make up for that fact. When he was still working for the church, he was in charge of the "Holy Sword Project". He was so obsessed with wielding a holy sword, that when he learned he couldn't, he turned his attention towards those who could. He kidnap dozens of children for the "Holy Sword Project", where he would perform heinous experiments on them, with fatal results for many. When the children weren't capable of wielding a holy sword, he simply has them all killed; there was only one child who survived. The church was so disgusted with Galilei, they excommunicated him, resulting in him seeking revenge against the church. He planned to do so by allying himself with the Fallen Angels, particularly with Kokabiel. When he notices that Kiba, the one boy who survived, became a knight under Rias Gremory he mocks him with the fact that all of those children who died were worthless and that he should have died with them, showing how little he cares for the children. Utterly heartless in his endeavors, it was no surprise that many would consider angels and devils having more humanity than him.
    • Diodora Astaroth, the Greater-Scope Villain of Volume 1 and the Arc Villain of Volume 6, first seems like a guy hopelessly in love with Asia, even trying to bargain with Rias to obtain her, but when Rias rejects his offers, some of his true colors shows when he kidnaps Asia and put her into a device that would drain her life force. When Rias and her peerage tries to rescue her, he reveals that he was the reason that Asia was kicked out of the church when he, a devil, pretended to be injured so she could heal him, and tried to capture her as part of his peerage. Asia was lucky to escape, as it turns out Diodora is a sex fiend with a nun fetish who goes to various churches, captures various nuns, and turns them into his sex slaves against their will. He not only reveals this with glee, but when fighting Issei he says it may be fun to rape Asia everyday whenever she calls out his name, showing he never loved Asia but just sees her as part of his nun collection. When Issei finally defeats him, Diodora still made plans for the life draining device to kill Asia should he fail to have her. Overall, while seemingly polite and charming, his actions cement him as one of the vilest villains of the series.
    • Rizevim Livan Lucifer, son of Lucifer and Lilith, is a hedonistic, wicked devil who believes Devils are meant to be beings of pure evil. To that end, he convinced his son to horribly abuse his own son Vali, using his son's wife as a hostage for that purpose. Rizevim then murdered his own son and abandoned Vali. Returning upon learning of Trihexa, the beast of the apocalypse, Rizevim seeks to use it to destroy the world and rule over what's left. Attacking the vampire race and also heaven to kill as much as he can in pursuit of the Grails to free Trihexa, Rizevim also abuses and tries to murder the gentle Asia Argento. When he is finally killed, Rizevim even uses his own soul as a means to unleash Trihexa, determined to take all creation to death with him.
  • Crazy Awesome:
    • Seriously,there is no limit to Issei's ability pull off all the crazy stuff he is able to do. To wit, he has: done a rescue mission to Asia by punching out a Fallen Angel so hard she bursts through the wall (out the window in the anime), barged in an engagement party full of devils to take back Rias, invented Dress Break and Bilingual out of pure lust, defeats Riser, an immortal phoenix, not with the use of his newly-found dragon powers, but by using a holy cross and holy water which he can't even use because he's a devil, but is capable to do so because his arm is a dragon's, powers up with lust and by using Rias' breasts, accidentally summons the Breast God (well Breast Fairy but still definitely counts), is capable of breathing fire to a shadow-using opponent, and was able to make the past users of Boosted Gear come back to the light and make them stop relying on Juggernaut Drive with breasts. If there's one thing Rias recruited to her group, it's the fact that she recruited the craziest character of the series. No one out-crazies Issei at all in this series. And yet somehow, he's also the Only Sane Man in the group (when he's not doing his lecherous ways).
    • Rias may count to a lesser degree too. Who's crazy enough to be willing to bare her breasts open just to let Issei get a power up in public viewing!? Also renovate Issei's house from a simple house into a six-story mansion with a three-story basement and an elevator overnight!?
    • Azazel too can count as one. The craziest idea he pulled off is that to capture the Issei clones he accidentally unleashed, he suggests the idea of using fishing on them. With porn as the bait.
    • Forget Azazel himself, the entire Grigori institute counts.
  • Counterpart Comparison:
  • Darkness-Induced Audience Apathy: The vampire war that takes place from Volume 14 to 16. On top of the conflict itself coming off as a side event to the revival of Khaos Brigade under Rizevim, virtually all pure-blooded vampires at the time were portrayed as barbaric people who only think of themselves, making it very difficult to care who comes out on top. The protagonists themselves have no investment in the war, nor any particular good will toward vampire society in general; their only concern was ensuring Valerie's safety. The Arc even comes off as Trapped by Mountain Lions, as the only changes from that arc to stick are a bit of Character Development for Gasper, and the inclusion of Valerie and Elmenhilde later on.
  • Die for Our Ship:
    • Despite being a harem and everything, people seem to not like Asia as much as the rest of the characters because according to the fans, she's too clingy to Issei to share with everybody else. This lightened up (for novel readers, at least) after the introduction of Fafnir, who adds many humorous moments to Asia's character and gives her a much needed power up.
    • Koneko isn't safe from this either, possibly due to her much more prudish behavior towards Issei than the rest of the girls. However, her character arc in Volume 5, which caused her to lighten up to Issei more, mitigated this a bit.
  • Draco in Leather Pants:
    • Raynare. She killed Issei with no remorse, mock him and telling him that the date was so boring that she couldn't wait to kill him. She killed the nun Asia with no remorse. Yet that doesn't stop people from whitewashing her and making her out to be a good person deep down. But she has no redeeming qualities at all.
    • Kuroka is one as well. While she does undergo a HeelFace Turn and was later revealed to have a Freudian Excuse for turning on her former master, she debuts attempting to kill Koneko and her friends.
  • Ear Worm:
    • The ED from the animes first season. It will get stuck in your head.
    • The "Oppai Dragon" song, performed by Issei's Japanese VA for the third season's second promo video, is probably even worse. Click at your own risk.
  • Ensemble Darkhorse:
    • Mil-tan has appeared in only a few scenes, and is one of the most discussed characters in the series. Take note, he's a Creepy Crossdresser. There are groups of fans who continue to insist Mil-tan is actually the supposedly dead Bible God and is just screwing with everyone because its funny.
    • Ophis is particularly well-loved by the audience too.
    • Kuroka is shown to enjoy a good degree of popularity in the fandom, and is possibly the only girl in the show itself to rival Rias and Akeno in popularity. All in all, she definitely does eclipse her younger sister Koneko in popularity. Perhaps coincidentally, her breast size is also third after Akeno and Rias among recorded characters. This is also possibly one of the reasons of her subsequent inclusion into the harem.
    • Among the Church Trio, Xenovia is far and away the most popular, mostly thanks to her extremely blunt personality.
  • Escapist Character: Issei to an absurd degree. He starts the series off as an Ordinary High-School Student, who's considered an unpopular, perverted loser by pretty much everyone along with his two friends. Then after joining the Occult Research Club, he spends all of his time with the most popular people in school, wins the undying love of no less than seven absolutely gorgeous women, all of whom have no problem sharing him, and starts a relationship with the most beautiful girl in school, who also happens to be a noble. He learns that he essentially shares his body with one of the most powerful beings in existence, takes level after level in badass in record time, gains the admiration of his peers, and becomes insanely rich after his new brother-in-law makes an incredibly popular TV show based on him. The guy goes from being The Everyman to becoming the fantasy of hormonal teenage boys everywhere before he's even reached his third year of highschool.
  • Evil Is Sexy: Raynare.
  • Fan-Preferred Couple:
    • Issei/Akeno seems to edge out the Official Couple Issei/Rias in terms of popularity. This is further enhanced by the fact that Akeno is the first girl in the harem that Issei goes out on a date with (barring Asia).
    • Some also prefer Issei/Kiba.
    • Issei/Yumi.
  • Fandom Rivalry: Some Attack on Titan fanboys don't look on DxD in a good way, if simply because they don't like how series protagonist Eren Yeager shares his voice with a Lovable Sex Maniac. This rivalry, however, is mostly one-sided, since the DxD fandom doesn't really care about AoT in one way or another.
  • Friendly Fandoms: More prominently with The Testament of Sister New Devil, Date A Live, Daily Life with Monster Girl, and Senran Kagura, but there is also a chance that a DxD fan may also be a fan of To Love-Ru (even though the respective fandoms are used to some gibes between each other).
  • "Funny Aneurysm" Moment:
    • One of the short stories of the series was about the Issei clones that Azazel had played a prank on Issei. It was mostly funny until the part where they had to use the memory-erasing machine Azazel had invented (at best, they could only erase the memory of the clones running around but didn't erase the fact that an Issei clone did it, leaving the victims thinking the real Issei had done it to them because it would damage their brain memory). At that point in time, it was hilarious, albeit a bit unfair to Issei who didn't really deserve all that. Fast forward to volume fourteen, and that memory-erasing machine incident suddenly doesn't become funny anymore thanks to the student council group using it to wipe off the memories of the students were the victim of a rouge wizard terrorist attack at the school, which leaves students traumatized of something but not what. This left a bitter taste to the student council and the protagonists.
    • Issei living together with Asia and using Dress Break on Riser Phenex's peerage becomes even less funny when his English VA, Scott Freeman, actually would be convicted for multiple counts of child pornography.
    • During the dodgeball game in Volume 3, Issei ends up taking a blow to the crotch to protect Kiba while the latter's attention is elsewhere, with Rias swearing vengeance as if Issei had just been killed. Fast forward to Volume 12, where Issei's temporary death leaves the Club stuck between depression and a lust for revenge.
  • Harsher in Hindsight:
    • The series is banned in New Zealand on the counts that it promotes child pornography. Then comes why Scott Freeman was unable to voice Issei in BorN, as it's revealed that he got arrested and convicted for multiple counts of possession of child pornography. It also makes the scene where Issei uses his Dress Break against Riser Phenex's peerage uncomfortable to watch in the English dub. What's even worse is that he was arrested months before BorN aired!
    • Asia being exiled from the church as The Heretic becomes more disturbing when Diodora, the devil whom Asia healed, raped quite a few nuns and got them exiled from the church as well.
    • The Khaos Brigade's terrorist attacks on the Three Factions becomes even more nightmarish when actual terrorist attacks would occur in the Middle East, such as those in Iraq and Syria, as well as in Europe, such as those in Paris and Nice. And all of these took place during the course of the series' run.
    • Akeno gets frustrated whenever her relationship with Baraqiel is mentioned. But by volume 7, we learn why she's upset with him... It was that Baraqiel actually failed to save Shuri Himejima, her mother, from being murdered by her own relatives.
    • In volume 6, Diodora Astaroth mentioned how he would enjoy to rape Asia while she screams for Issei's help. It becomes a lot harder to swallow after film executive Harvey Weinstein was dismissed from The Weinstein Company in 2017 following reports of his history of sexual misconduct and mistreatment of female employees and actresses, including her Real Life namesake, Asia Argento. And not just Weinstein. That same year, a period of accusations of sexual assault and harrassment by much respected and famous actors and other film/television industry big shots that destroyed fans' passion for them and their work.
    • At first, Rias and Sairaorg are lectured for using their king pieces to fight in addition to commanding their pieces. But then, we learn that Bedeze Abaddon and Roygun Belphegor have used their King pieces for not-so-legal reasons in the Rating Games.
  • Heartwarming in Hindsight:
    • Asia Argento was an orphan and adopted into the Church and during her time as a nun, was referred to as sister by the other church officials. Several volumes later, Dulio Gesualdo reveals that he views those who came from churches as his brothers and sisters and has a fondness for orphaned children.
    • Akeno's engagement to Issei when her voice actress Shizuka Ito married in December 2012.
    • Ravel having a child when her English VA Brittney Karbowski would have a daughter in October 2014.
  • Hilarious in Hindsight:
    • Yoko Hikasa played Seraphim, a vampire ninja, in Is This a Zombie?. Here, she plays Rias Gremory, a devil, who is the master of her servants, particularly the vampire Gasper Vladi.
    • Jad Saxton voicing Koneko Toujou became amusing once you realize that she also voiced Carla, who resembles a cat like Koneko, in Fairy Tail. In she voices Koneko Toujou, who is a nekomata. The fifth Blu-ray/DVD release of Fairy Tail was released one month before the Blu-ray/DVD release of High School DxD. What's more, Saxton has a cat named Granger.
    • In Volume 3, Rias scoffs at Xenovia's statement that she, the sister of a Satan, would ever team up with a Fallen Angel. One volume later, the Three Factions form a peace treaty, and said Satan enlists the leader of the Fallen Angels, Azazel, to become Rias' club advisor.
    • Vali notes back in the fourth volume that the current red-white dragon rivalry was a bit unfair because Vali's the descendant of the old Lucifer and Issei's the son of a common Muggle. Vali wishes that Issei's parents were a bit special so they can have a more interesting match. Now that Great Red and Ophis are both Issei's parents by proxy by creating a body for him from Great Red's flesh and Ophis' powers, let's just say Vali's wish came true. Though seeing as Vali's a Blood Knight, he's probably pleased with the development.
    • Also from the fourth volume was Vali bringing up the setting's Super Weight, speculating that even Sirzechs wouldn't rank among the Top 10. Later, Sirzechs reveals his true form, a human-shaped mass of Power of Destruction, which Word of God states does put him amongst the Top 10.
    • The volume one afterword has the supposedly final battle will be between a guy who can breath flames and Issei supposedly shooting out a blaster. Now read how the final clash between Issei and Jabberwocky went in volume 12.
    • During the Familiar side story, Issei is recommended Tiamat, despite his concerns about being a Satan-level Dragon King. Rias suggests that he will have decent compatibility because he is already housing the soul of another legendary Dragon, Ddraig. We later learn that Tiamat actually hates Ddraig for borrowing her treasure and losing it.
    • For those who have played The Last Remnant, whenever Kiba calls Irina Shidou, you might be reminded of how Rush always calls Irina.
    • Rias is rumored to be from Europe according to Motohama. Come several volumes later, Rias and her friends travel to Romania, a country located in Europe.
    • Mil-tan contracts with Issei so a devil can make him a magical girl. Issei considers it impossible and says he'd have better luck going to an alternate universe. Some time later, Azazel, as a member of the ORC where Issei works, makes a gender-swap ray gun...
  • "Holy Shit!" Quotient: Among the highest in the history of light novels.
  • Ho Yay: Believe it or not, now has its own page!
  • Internet Backdraft: The third anime season, BorN, created a huge backlash among the fandom, given how Tetsuya Yanagisawa went against the recommendations Takao Yoshioka and Ichiei Ishibumi regarding the distillation of volumes five through seven. TNK and Ishibumi have since admitted that due to the debacle, they decided remain faithful to the light novels for the next season.
  • Launcher of a Thousand Ships: Issei, though this isn't really surprising.
  • Memetic Badass:
    • Issei motherfucking Hyodo. What did you expect from somebody who has just as many Badass tropes as the freaking Dragonborn?
    • Also, GARspernote , Azazelnote , and Sirzechsnote  are very prominent in the Imageboards.
    • Vali is also seen as this by his supporters. Being an Accelerator Expy who took almost 10 volumes for Issei to outdo completely certainly helps matters.
  • Memetic Molester: Good lord, Riser. Freed and Diodora have it even worse.
  • Memetic Mutation:
    • Somewhat a meta example: if any volume is delayed for its release, expect people to post about Ishibumi and trains. Fandom just went with it.note 
    • Doctor Crimson and Canary Maid which is especially prevalent at Imageboards.note 
    • The first ending credits of the anime. Probably has to do with Koneko-chan shaking that.
  • Moe: Lots of the girls in the series. Asia and Koneko are perhaps the most obvious cases.
  • Most Wonderful Sound:
    • BOOST!
    • When Ddraig gets to use his rival's power: DIVIDE!
  • Never Live It Down: In general, BorN gets a lot of ridicule thrown in its direction for altering the storyline to the point that Ichiei Ishibumi wrote the spin-off novel, EX, to declare it Canon Discontinuity and pull an Author's Saving Throw on it.
  • Rewatch Bonus: Oh so many. Even the author recommended to re-read the entire series before the fourth arc started.
  • Ron the Death Eater:
    • For whatever bizarre reason, Issei is made to be a much bigger loser then he really was at the beginning of the story to make whatever OC insert fanfic writers make to make him look better then Issei, usually accompanied with stealing Issei's harem members if Issei is still around in the story if not outright replaced entirely.
    • Rias also gets this, due to people exaggerating her selfishness from early on in the series, completely missing the point that as a devil, regardless of how kindhearted they could be, are still inherently selfish to a fault, with Rias not being the only devil that's portrayed as this despite good intentions.note 
    • Not just Rias, but the Gremory family like Sirzechs, Venelana, Zeoticus and some members of the Occult Research Club get this as well.
  • One-Scene Wonder: The Breast God when she appeared before Issei to help him defeat the evil God, Loki.
  • One True Threesome: Issei/Rias/Akeno is probably the most popular out of all of the show's OT3s.
  • Periphery Demographic: To the surprise of Ishibumi, there are a lot of female fans of the series despite the numerous amounts of Fanservice. Heck, one bookstore had the series volumes in the women section.
  • Signature Scene:
    • Issei's "death" at the hands of Raynare which set the tone for the story to be much more than a basic Harem series.
    • Issei waking up in his bed next to a naked Rias.
  • Some Anvils Need to Be Dropped: Do not let hatred consume you. Even if someone did wrong you in the past, cursing them is something you will likely regret later. Akeno learned this the hard way.
  • Suspiciously Similar Song: The track "Memories of That Day" from BorN may remind some of the main theme from the Love Story soundtrack by Francis Lai.
  • They Changed It, Now It Sucks!: Many fans who read the light novels criticize the anime's placement of volumes 5-7 in BorN. It ended up being so widespread that Ichiei Ishibumi and Kadokawa actually apologized for what happened.
  • They Wasted a Perfectly Good Character:
    • A small hand of people tend to believe that Raynare died way too early in the story. Some even think that she should have survived, and make for an interesting addition to Issei's harem as a Token Evil Teammate of some sort.
    • The Heaven characters in general have also been greatly underutilized when it comes to the overall story. Apart from Irina, who's part of Issei's harem, Heaven's Angel characters only make rare appearances from time to time, and Heaven as a location only gets it's day in the limelight as the setting for Volume 18.
    • Samael, a fallen angel/dragon hybrid known as the Dragon Eater, who Azazel states was created from God's hatred. His very existence is lethal to dragons, and just exposure to his his blood is enough to kill Issei, debilitate Vali, and even greatly weaken Ophis. He's so dangerous that he was locked away in Cocytus, the deepest part of the Underworld, essentially making him another version of Satan. Despite being one of the most conceptually terrifying beings introduced in the story, his only appearance so far is when he's raised from his prison by Hades, who completely binds him up and gives him to the Hero Faction, so they can utilize him as a weapon. After the Hero Faction is defeated, Samael is resealed and hasn't even been mentioned since then.
  • They Wasted a Perfectly Good Plot: The vampire civil war that takes place in volumes 14 and 16. The only reasons why the vampires got involved in the plot was just so the writer could introduce Rizevim Lucifer, and to give a bit of much needed Character Development for Gasper. Some fans thought that the vampire civil war needed more time to take in and develop than what was given.
  • Tough Act to Follow:
    • The show-stopping pole-dance ending-song sequence Study X Study from the anime's first season, with its energetic and upbeat song and astoundingly fluid and well-designed animation (all animated by one man, mind you) set such a high standard (and became a Cult-Favourite amongst fans) that the second/third ending sequence from New simply couldn't top it, and hence the crew didn't even try.
    • The vampire civil war gets this reaction for taking place just moments after the Final Battle against the Khaos Brigade's Hero Faction; helped by the immense build-up the Hero Faction had until that point. Not only were the vampires incredibly underdeveloped in comparison to the Heroes (Cao Cao in particular), the vampire war, itself, comes off as an irrelevant side-story just to have a setting to introduce the new leaders of the Khaos Brigade.
  • Unexpected Character:
    • Very few readers expected that Ravel Phenex would join the Occult Research Club when volume 10 was released.
    • No one expected Ophis to join the Occult Research Club.
    • Given that Elmenhilde Karlstein was a minor character who was Put on a Bus after volume 16, her appearance in volume 21 to become Issei's lover and eventually, his pawn in his peerage, is surprising.
  • What an Idiot!:
    • Issei Hyoudou, who is unable to realize the girls' feelings towards him. Though it's justified, given the psychological damage he received from his experience with Raynare. He gets better.
    • The real crown goes, though, to the Two Heavenly Dragons (Ddraig and Albion), who decided during the great war to fight God, Satan and the leader of the Fallen Angels. They were quickly dismembered and the Sacred Gears - Boosted Gear and Divine Dividing - are what's left of them stored. It should be noted that in the last example it was implied that the process of sealing the two dragons took everything the Three Factions had, may have contributed to the death of God, and left the warring sides too exhausted and spent to continue their war.
  • Win Back the Crowd: BorN left a bad taste in fans' mouths due to Tetsuya Yanagisawa making several changes and adding an anime-original arc. Fortunately, they didn't dwell on it too long once the EX spin-off was written and the fourth season, Hero, was produced.
    • It was further helped when Life 0 of Hero premiered on April 10, 2018. Many fans were concerned about the switch to Passione and the resulting art shift, but most of those were won over when the first episode turned out to be a (mostly) beautifully-animated retcon of BorN's Juggernaut Drive scene, complete with the long-awaited Gropin' Dragon Song and other important details that TNK left out of their version.
  • Woolseyism: For their dub, Funimation has noticeably added a fair dose of sexual references and cranked up the eroticism in the dialogue, most notably with Akeno. But given the show's nature, it works brilliantly. Most of the Funny Moments page is done using dub vs. sub, as a matter of fact.
