History YMMV / EromangaSensei

* FanPreferredCouple: Although Sagiri certainly can be called the most popular character of the series and is officialy it's face, the LargeHam nature of Elf and the increasing emphasis on her accent in the anime quickly brings the Elf/Masamune pairing forward, at least among Western fans.

* HarsherInHindsight: Episodes 9 and 10 certainly do not reach Oreimo's level in this, but they are definitely perceived as very cruel when you see how the Elf and Muromasa express their feelings to Masamune and promise that they will achieve his reciprocity. Oh, it obviously will not happen.

** Parts of the Western audience was already not too happy about the show in general, since it came off as a FollowTheLeader of [[LightNovel/{{Oreimo}} the author's previous work]], which is already the source of a major BrokenBase among the Western anime fandom. Especially since BrotherSisterIncest, just like ''Oreimo'', is a major plot point; though it dodges the incest taboo by the fact that Masamune and Sagiri are NotBloodSiblings, it more than makes up for it in controversy by [[{{Lolicon}} significantly lowering the ages of the girls from high school-age to pubescent]]. Even among those inclined towards the show, [[ItsTheSameSoItSucks a few dislike the repetition]].

* InternetBackdraft: [[spoiler:A brief cameo in an early anime episode shows [[LightNovel/Oreimo Ruri Gokou]] on the TV, which wouldn't cause much fan anger except that she was wearing the same kimono [[ShipSinking as when Kyousuke rejected her]], as well as saying she was at the festival alone. The Kyousuke/Kuroneko shippers who still haven't gotten over the novels' endings took that as [[TakeThatAudience twisting the knife]] and blew up on the web. However, a later scene showing that Kyousuke and Kirino are still friends with Kuroneko softened the blow]].

** Parts of the Western audiences were already negatively tuned to this show, since it repeated many elements of the previous work of the author, including BrotherSisterIncest as a major plot thread; though it is not a blood relationship this time, the lower ages of the cast more than compensates. Even among those inclined towards the show, a few dislike the repetition.

** Sagiri causes a rather ambivalent attitude among some fans, as some seem to enjoy her CovertPervert personality, but others believe that this very much vulgarizes her as a sweet character and is completely inappropriate in such a work.
** Masamune, on the other hand, causes misunderstanding among some fans, since his fear of losing Sagiri as part of the family, and instead becoming a couple with her, is completely meaningless, since a romantic interest or even a wife also counts as family for most people.

* BrokenBase: Is this a new, full-fledged work with an original storyline, or is it an attempt to retry writing ''LightNovel/{{Oreimo}}'', removing IncestSubtext and the ending that angered many? As the adaptation began, this was accentuated as it repeats the style of the previous work.

* DieForOurShip: Fans of Yamada Elf are inclined to dislike Sagiri, as she is a fairly obvious official pair for Masamune because of the obvious incest character of the show.

* AmericansHateTingle: Although the show is the most popular in its season in Japan and had high ratings, some in the West dismiss it at best because of the author's past reputation and the pseudo-incestuous relationship between a 12 year old girl and 15 year old boy.

* IdiotBall: All the romantic intrigue could end before the show, if Masamune realized that wife is also a member of the family. This fact escapes and from Sagiri too, because of what the development of their relationship becomes only more confusing.

** Some think the 15-year-old protagonist developing a romantic relationship with his 12-year-old stepsister and discussing dicks with her classmate is off-putting. This becomes even worse because of the increasingly revealing CoverPervert nature of Sagiri and her strange fixation on "vulgar" things. Eventually not all Western viewers would be happy to see how, [[spoiler: for the purposes of "comedy", a 12-year-old girl pulls off panties or draws porn for her older stepbrother.]]

** Some think the 15-year-old protagonist developing a romantic relationship with his 12-year-old stepsister and discussing dicks with her classmate is off-putting.

* {{Squick}}: Some think the 15-year-old protagonist developing a romantic relationship with his 12-year-old stepsister and discussing dicks with her classmate is off-putting.

* WinBackTheCrowd: This series marked the return to popularity of its author, after the end of his previous work caused a scandal in the anime community.

* It may happen that the interaction between Masamune and his [[Creator/YuichiNakamura father]] in the 11th episode will be impossible to take seriously because of NarmCharm, since it looks like the Tatsuya Shiba's care of a young Kirito. Moreover, Nakamura performs three roles in this show, including the cameo of two of his characters from other BrotherSisterIncest series. The son clearly [[SarcasmMode followed his father's way]], lol.

* GeniusBonus: One of the reasons for the success of this series is the light it shines on the nuances of work on light novels, including a discussion of concepts and the creation of illustrations, which makes it quite popular among people from the literary and artistic community.

* AmericansHateTingle: Although the show is the most popular in its season in Japan and had high ratings, some in the West dismiss it at best because of the author's past reputation and the incestuous relationship between a 12 year old girl and 15 year old boy.

* BestKnownForTheFanservice: Many people are more aware of the harem cast and incest than the major plot about the literary community.
* BrokenBase: Is this a new, full-fledged work with an original storyline, or is it an attempt to retry writing ''LightNovel/{{Oreimo}}'', removing IncestSubtext and the ending that angered many? As the adaptation began, this was accentuated as it repeats the style of the previous work.

** Masamune, on the other hand, causes misunderstanding among some fans, since his fear of losing Sagiri as part of the family, becoming a couple with her, is completely meaningless, since a romantic interest or even a wife is also are family for a people.

** And that's not to mention the fact that [[Creator/AkaneFujita Sagiri's seiyu]] plays another younger {{Tsundere}} main heroine with platinum hair [[LightNovel/AkashicRecordsOfBastardMagicInstructor in the same season]].
* HypeBacklash: Given the {{Moe}} nature of this show and its popularity as a source for memes, it's no wonder that the growth of its popularity has become the object of criticism among alleged purists from the anime community. Add to this the popularity of the original novel and the dislike of the incest plot among many Western viewers, and you will understand how mixed attitudes have developed about its popularity.

* FanPreferredCouple: Although Sagiri certainly can be called the most popular character of the series and are it's face, LargeHam nature of Elf and the increasing emphasis accent of her in anime, quickly brings Elf/Masamune forward at least among Western fans.
* FriendlyFandoms: With fans of ''LightNovel/{{Oreimo}}'' and ''Manga/HimoutoUmaruChan'' because of similar sibling and comedy plot settings, obviously. Although Eromanga and Umaru have different end results, in most cases, people who like one of these series will like the other. Fans of ''TheIrregularAtMagicHighSchool'' usually also like this series because they both go out in one publishing house and have a powerful imouto-moe as one of the bases of popularity.
* JustHereForGodzilla: In a surprising reversal, you'll have some fans vocal in citing their reason for watching the series is not [[BestKnownForTheFanservice for its fanservice]], but for its [[SugarWiki/AwesomeArt stellar animation]].

* FountainOfMemes: Sagiri and Yamada Elf seem to be specially made for this, like the hot younger stepister and the crazy LargeHam rival, so they steal virtually every scene where they appear, and many of their moments are used as [[https://s-media-cache-ak0.pinimg.com/originals/83/85/b4/8385b404ea75bbf3413aefa56f4d88bd.gif#ActualImage comedic]] [[https://68.media.tumblr.com/a51bc4dc62a349c4e24d931d352b65c3/tumblr_op805ndBd61vviqkjo1_540.gif#ActualImage gifs]].

Fans of ''TheIrregularAtMagicHighSchool'' usually also like this series because they both go out in one publishing house and have a powerful imouto-moe as one of the bases of popularity.

** Even among Eastern audiences, the opinion was splited. Many considered Sagiri less TheWoobie and more TheScrappy because she kept demanding Masamune's attention without any grateful.

* HypeBacklash: Given the {{Moe}} nature of this show and its popularity as a source for memes, it's no wonder that the growth of its popularity has become the object of criticism among alledged purists from the anime community. Add to this the popularity of the original novel and the dislike of the incest plot among many Western viewers, and you will understand how mixed attitudes have developed about its popularity.

* SignatureScene: Sagiri draws in her underwear on the bed, and dialogue about the dicks between Masamune and Megumi.
