@Freestyle No, but it seems to have gotten a sudden spike in popularity as of late, which I find interesting.
@Pokari You made the claim that this story seems to be rooted in a certain belief ultimately because this basic premise which has been showing more recent popularity (at least with translators) equally between male and female protagonists as an indication that it fit in with a belief you hold (to clarify since it seems that you misunderstood my intention, my use of the term is
not a reference to the veracity of the belief but merely a qualification that is factually true, there's a fair amount of bias and relatively incestuous studies and references in the behavioral sciences on top of science itself not always being correct just as medical science once thought that humor treatment could solve almost any problem, however regardless as to if it is true or not you believe it to be true thus it is a belief, I am just refraining from calling it a fact in addition to it being a belief as the issue can get a lot more complicated than the simple broad statement that it is, which can lead to instances where it wasn't going on being considered to have it going on), while I have no problem with you taking whatever message suits you from any given piece of media death of the author can very easily disrupt conversation and turn it completely useless. Sure you
can find support that this is a story about women specifically not being taken seriously, but conversely I could draw comparisons between Genghis Khan and toasters if I was so inclined, this does not mean that toasters are going to start a bunch of wars and try to take over China. Conversely there's also evidence to suggest that this specific story is one that's not being made at the behest of gender (such as the woman in the original party, and that the person who's taking her serious now is a man) but just a story of someone not being taken seriously who happens to be a woman. One of the problems that I typically have with the 'death of the author' in regards to discussions on media is that the media is often fictional, while you can draw conclusions and pull out what you want since the media is not bound by the rules of reality your conclusions can often have no bearing beyond the emotional impact they give you, and if that's the only bearing they don't add much of anything to a discussion if you ask me. Besides, honestly I wasn't even looking at the author precisely, I was musing about the tendency for various Webnovels with a similar premise as this one to get the popularity they do, noting what I presume is resonating with the audience emotionally with this story, "The Vengeful White Cat Lounging on the Dragon King's Lap", "Lv2 kara Cheat datta Moto Yuusha Kouho no Mattari Isekai Life", "The Labyrinth Raids of the Ultimate Tank ~The Tank Possessing a Rare 9,999 Endurance Skill was Expelled from the Hero Party~", "Asobinin wa Kenja ni Tenshoku Dekiru tte Shittemashita? ~ Yuusha Party o Tsuihou Sareta Lv 99", and to a lesser extent I'd say "Seirei Gensouki", "Otomege Sekai wa Mob ni Kibishii Sekai Desu", "The Duchess of the Attic", and several isekais too. Out of all of these the only ones that seem to have gender play a part in it would be "Otomege Sekai wa Mob ni Kibishii Sekai Desu" very overtly and I'd argue "The Duchess of the Attic" as well, (Maybe "Asobinin wa Kenja ni Tenshoku Dekiru tte Shittemashita? ~ Yuusha Party o Tsuihou Sareta Lv 99" too, I haven't read that one personally), this leads me to believe that the gender angle isn't one that's really resonating with the Japanese audience, despite all of these series being successful enough to get manga adaptations.
TL;DR- I was talking about how a lot of series similar to this have gotten popular lately (as shown by them getting adapted to other media forms). Almost none of them talk specifically about gender and if anything seem to have male protagonists more often. While I've got nothing against your own personal take, this is a piece of fiction and so the only truths of the world that you'll be able to get out of it are the ones you yourself see in it, so I disagree with your own personal take. Also I said 'belief' because it is a belief, you can believe in something that is true which makes it a fact and a belief, and you can believe in something that is false making it only a belief, calling it a belief is merely avoiding making a claim of accuracy, not calling it into question.
