History Anime / SevenMortalSins

* BleachedUnderpants: Another thing this series has in common with its predecessor ''Anime/QueensBlade''. Between the end cards of the twelve episodes and the booklets that come with the Blu-rays, many Hentai artists have contributed to this series.

** The second Blu-ray exclusive Short Special is about Leviathan replacing the band-aid she uses as underwear with a new one, but the scene is initially framed as her doing [[ADateWithRosiePalms something else in the bathroom]].

* {{Gainaxing}}:
** At one point during the BeachEpisode, Lucifer's breasts bounce wildly when she ''calmly turns aside''. What's more impressive is that her no-no bits remained covered, despite the fact that if her bikini isn't tight enough to prevent such a movement in first place then it shouldn't be able to prevent her breast from slipping off either.
** This trope is the bread and butter of the ''X-TASY'' mobile game, as the character models - both the full portrait seen on the menu and cutscenes and the chibi version used for battles - are animated with heavy usage of JigglePhysics so that the breasts are always bouncy.

* ArtisticLicenseReligion: A curious example. From Maria's behavior and dialogue it's possible to infer that Christianity that exists in the world of the anime is near identical to ours, but the very premise of the anime – Lucifer only fell down on modern times and the SevenDeadlySins can change – shows that it can’t be the exact same thing, which gives the writers some freedom to modify some details. [[spoiler:Indeed, turns out that not only this Lucifer fell down millennia after her biblical counterpart, she is not actually the first angel to fall, just the most famous one.]]

* LoadsAndLoadsOfCharacters: ''X-TASY'', as expected of a game of its genre. Putting together the Sins and the Virtues already gives it a cast of 16 (plus Maria, who isn't a playable unit but shows up in-story). Then it adds literal dozens of new characters for the gacha.

A Mobile Game titled ''Sin: Nanatsu no Taizai X-TASY'' was released in June 2nd, 2021. It features both the Seven Deadly Sins and the Seven Heavenly Virtues, as well as original characters. It received an international release in April 25th, 2022.

* LyricalDissonance: One of Lucifer’s attempts at becoming a more popular singer than Astaroth involves making a stereotypical idol music video, complete with frilly dresses, upbeat music and an overly-sugary montage of Lucifer doing girly things alongside Maria and Leviathan. The thing is, she is still using the downer lyrics Astaroth, Demon Lord of Melancholy, thought up.

* SequelHook: [[spoiler:Lucifer may have defeated Michael, but the God and the other members of the Heavenly Virtues are still in Heavens, planning to purge Earth and Hell to create a new world from scratch. The series ends with Lucifer and the Mortal Sins preparing themselves to wage war against God.]]

* CastFullOfGay: About the ''entire'' cast is interested in other women. This even extends to the ''nameless extras" as the beach episode has several lesbian couples entranced by Lust's beauty.

-->'''Belphegor:''' ''It’s cheaper to re-skin the same outfit in different colors."

* SlutShaming: Defied and then Inverted. Lucifer explains she doesn’t see anything wrong with loveless sex, and even mocks Asmodeus in her face for thinking that “evangelizing about the benefits of sex” is an action sinful enough to qualify her as a Mortal Sin.

* StealthPun: The third Blu-ray exclusive Short Special shows Satan trying to give children their Christmas presents, complete with a matching outfit. That’s right, [[spoiler: ''Satan'' was cosplaying as ''Santa''!]]

* ThroughHisStomach: Attempted by Leviathan in episode 2 when she offers to cook a “Hellish full course meal” for Lucifer. It doesn’t work, but Lucifer did enjoy the food.

* TranslationConvention: Episodes 3, 4 and 7 respectively take place in Miami, London and Paris, so it’s safe to say that a good chuck of the dialogue in those episodes isn’t actually being spoken in Japanese. As for the main characters, the Mortal Sins are explicitly stated to have been alive for centuries, if not millennia, and their “job” requires then to interact with humans, so them knowing many languages is no surprise (But which language they speak when they are not in the presence of humans is anybody’s guess). And Maria is a high school student, so her knowing English also isn’t a big deal, though admittedly the idea that she just so happened to also being fluent in French does pushes the WillingSuspensionOfDisbelief a bit, even if it’s not impossible. (Alternatively, the nurses in the hospital in Paris were the ones speaking English for her convenience.)

* WimpFight: The “fight” between Leviathan and Astaroth in episode 10. It starts like you would expect of a battle between Demon Lords, but it quickly degenerates into MudWrestling. When the episode cuts back to those two later, they both have completely lost control of the situation. Leviathan is even being dragged along with Astaroth by the current of a river [[EpicFail despite being able to control water]]!
* WorldOfBuxom: The only girls in the series with a small chest are the TokenMiniMoe of each group. Everybody else has a breast size that varies between “moderately big” and “humongous”.

Not to be confused with the '''other''' ''Manga/TheSevenDeadlySins''.

* InvisibleToNormals: Regular humans can't see angels or demons, with the exception of Maria. It's later show that demons can turn off their invisibility so they can interact with humans and get them to sell their souls.
