And You Thought It Would Fail: The announcement of the series getting an anime adaptation led to it being looked as Snark Bait, as the name and plot made people think it would be either another Sword Art Onlineclone or a generic ecchi harem series.note For the record, the show does not fall into this category, and the moments of fanservice it does have are either Played for Laughs or treated diagetically. Instead, the series became extremely popular, becoming easily the most discussed new anime of its season. Even with some amount of Hype Backlash discussed below, the series impressed many people.
Hestia has become a pretty polarizing character after the anime came out. Excluding the memetic ribbon, many love her and find her to be hilarious and cute especially in her interactions with Bell, while others hate her for her excessive clingyness while believing she doesn't deserve Bell and want him to end up with one of the other girls.
Loki's excessively perverted nature is either hilarious or just plain cringeworthy. There's some very obvious implications of an older woman groping younger girls.
Broken Base: The Animated Adaptations for both series is criticized to be pretty hard to bear... only for people who have read the novels. In general, both anime adaptations have adapted the source material in a way which allows for the overall story to flow better and to emphasize certain crowd-pleasing elements, but skips more minor Foreshadowing scenes and world-building details in order to do so. This appeals to the general audience as well as those who haven't read the light novels, but alienates more hardcore fans.
The rushed pacing of the original series' anime adaptation. On one hand, there are those who have been enjoying the show; particularly people who haven't read the light novels. On the other hand, detractors feel that the story is rough to follow due to the amount of detailnote Which basically involves much of the elaborate world-building. A lot of viewers asked for spoilers just to know how the universe works. being left out in order to rush through, and show off just the major events. The worst of the criticism occurred when it was shown in episode 9 that the 4th light novel was done in a single episode. Skipping out on some pretty big scenes, such as the God's meeting, and pretty much everything concerning Welf's backstory.
The anime adaptation of Sword Oratoria also has this. On one hand, as a normal show, it is a decent show focusing on the adventures of the Loki Familia, in particular its two lead characters Aiz Wallenstein and Lefiya. On the other hand, anyone who has read the light novels or read the manga heavily criticise the show for being rather unfaithful to the source material; in particular completely failing to get into the head of the singular protagonist, Aiz Wallenstein, in favour of staying with Lefiya, who was simply a major viewpoint character. Key scenes for Aiz are frequently told from Lefiya's perspective in the anime, especially when Oratoria overlaps with the main series, and thus much of the nuances of the source material and Aiz's character is lost. Some of this criticism abated between episode 4 to 8, when Aiz was given prominence, but resurfaced when series important interactions between Bell and Aiz were once again cut in favour of Lefiya's sidestories. These examples are especially egregious for Sword Oratoria, as a highly faithful and well-received manga adaption had already been in serialization long before the anime started which the adaption could draw from; unlike the main series, which had no other examples besides the original material to draw from.
Die for Our Ship: Hestia gets this from Bell/Aiz shippers. She's accused of "cockblocking" Bell thanks to exacerbating the lack of interaction between the two, as she actively keeps Bell away from Aiz. On the other hand, many who ship Bell/Hestia constantly criticize Aiz for being seemingly cold to Bell, and argue that Hestia blatantly cares for him more.
Epileptic Trees: Syr and Freya potentially being the same person has become popular, especially after realizing that Syr was an old name of Freya when she was in disguise back in her mythology. It also helps explain how Freya claims to have met Bell, since at no point is the audience shown Freya meeting Bell. A scene in the anime right before Bell first meets Syr hints at the possibility. The way Bell gains his spell is very blatant about hinting the possibility, since the grimore just happened to be left at the same pub Syr works at, who gives it to Bell when she could have easily given it to someone else.
Evil Is Sexy: Freya, the Goddess of Beauty, and perhaps the closest thing this series has to a villain so far.
Ishtar even more so than Freya. She and her Familia are involved in a lot of unsavory activities including human (and demi-human) trafficking, forced prostitution and human sacrifice
Bell's fight against Ottar's trained Minotaur in episode 8.
The fight against the Goliath in the season finale ends with a lot of "main" characters (basically all the familia members excluding the Loki Familia, who left to go back to the surface before the Goliath appeared) having a CMOA, and in the very end of the fight they all release their limit breaks, sure it does nothing as it was just to stall for Bell's attack to charge but it's still completely epic looking, then topped off by Bell's new skill Hero Strike, which cuts the monster in half, it isn't even enough.
Bell attaining the Argonaut Skill and using Firebolt, where he One Hit Kills a baby dragon.
Hype Backlash: Having enjoyed as close to an anime can get to "universal praise" during its run for its refreshing take on ribald RPG humornote Out of the more famous RPG-Mechanics Verse light novels of The New '10s, it is unusual for its lack of a Genre Savvy gamer protagonist and spends a fair bit of the early episodes being a Loser Protagonist; the cast instead acts more like Player Characters., overexposure to the hype and especially to Hestia and her popular outfit drove significant portions of the anime community to lash out at the show and its fanbase, as evidenced by masses of reviews left long after the series' conclusion. Among many insular communities, DanMachi is simplified to "That Show With the Boob-Ribbon Girl" and rarely recommended, despite its relatively good critical standing.
The anime adaptation of Sword Oratoria also received a bit of backlash, though less than the original, with many viewers (generally the people who had knowledge of the manga, light novel or even the main series anime) lashing out at the overall more rushed pacing and lower budget of Sword Oratoria compared to main series, as well as the anime's failure to deliver on the in-depth look into Aiz Wallenstein which had been advertised and which had drawn many people in.
Padding: Bell's fight against the gorilla during the Monster Festival is seen as this for a lot of people with claims being made that all the running around was unnecessary had Hestia just given Bell the newly crafted goddess-knife right away.
It's worth noting that while this was true to the light novel, in the manga (which was written by the author afterwards) they give Bell the knife right away.
Replacement Scrappy: Lefiya gets a lot of hate for being essentially a worse version of Bell. To elaborate; Lefiya has a crush on Aiz, wants to be strong, and is very timid, the same way Bell is. The problem is Lefiya is a level 3 adventurer, compared to Bell being level 1 at the start, has a extremely broken ability that allows her to essentially use any magic she wants, and can easily one-shot a Minotaur. The kicker is that Lefiya is a Static Character and never develops while Bell does. This can be seen in how Bell's response to being called weak is to go and actually train and improve, and he tries making some progress with Aiz while Lefiya just acts awkwardly around her and when called weak simply curls into a ball and cries. She can also be highly vindictive and prone to jealous rage, especially towards Bell, whom she has actually attempted to seriously maim and kill for minor incidences; which has furthered her detractors. This issue is compounded in Sword Oratoria's anime adaptation, where she frequently has anime-original daydreams of Aiz which either breaks the serious atmosphere of the scene, or eats up time which could have otherwise be spent on Aiz's backstory/development. The anime also flanderizes her clinginess to Aiz to the point where she seems more like an actual abusive stalker than a frequent comrade. She is also outright dismissive towards Bell for spending time with Aiz in the anime, compared to the Light Novel where she was a bit nicer, it just makes her more intolerable.
The Woobie: Liliruca. It's hard not to feel sorry for her when you see more of her backstory, such as losing both of her parents, then being constantly abused by adventurers and betrayed by people she thought she could trust. The anime makes sure to portray her getting kicked around by selfish people who seem to do it For the Evulz. It's tempting to also call her a Jerkass Woobie given she still left Bell to die after stealing his gear while he was fighting tough monsters. Yet, considering how she gets treated in the rest of the episode, it's still very hard to not feel sorry for her.
Complete Monster: In the Date A Live crossover campaign Ais Catastrophe, the false Kaguya Yamai, obsessed with Isaac Westcott, willfully merges with his personality. After entering the world of Orario alongside Shido and several of his spirit friends, "Kaguya" feigns being worried about the missing Yuzuru Yamai, while also impersonating Kurumi, to instill discord between Shido's spirit friends and the Loki Familia, leading to the Loki Familia's Bete becoming mistrustful of the spirits and Ais/Aiz Wallenstein attacking Tohka/Touka. This leads to Ais getting turned into an Inverse Spirit by a Sephira Crystal which the false Kaguya had implanted in her in the middle of the fight, all to ensure Ais would carry out the false Kaguya's goal of destroying Orario. When her plan of having Ais destroy Orario fails, the false Kaguya takes back the Sephira Crystal and makes plans to destroy Orario with spacequakes herself.
