I think some of the real problems with moe as used in anime’s that the characters are hardly ever relatable to female viewers, that’s if you take their personalities and behaviours into consideration that they start to resemble stereotypes of women. The tsundere woman’s always hard first, soft later; a bitch before becoming a softie. The yandere woman’s insanely in love yet hardly resembles women with actual mental illnesses (not that there aren’t any anime dealing with mental health issues in a realistic fashion but when moe takes over, that’s when it becomes inconsiderate).
If moe were a database as hypothesised by Hiroki Azuma, then it’s going to be a database of stereotypes that are endlessly mixed and matched but with little resemblance to the actual women in question. That’s practically the problem with the Fate/Stay series where the characters are assembled for their database elements, yet some of the character designs bear little resemblance to the people they’re based on and it can be bad when it comes to doing research on what you’re basing your character after. It’s one thing to portray Leonardo da Vinci as a woman, but when it comes to making him/her into a constellation of anime cliches that’s when the character design fails.
If moe were a database, then there’s bound to be shortcomings for the database model when it comes to inspiration for the characters’ personalities and appearances where if it were generated by expectations of stereotypes then it’s going to fall short when it comes to establishing characters as individuals so that’s why it’s necessary to be inspired by real life as well. (That’s also the problem with TV Tropes fiction, it’s based on stereotypes and cliches instead of things and people the author experiences and encounters in real life.)
Using real life as inspiration can make characters less stereotypical in some aspects, in the sense of resembling an actual person if not in appearance or at least something that exists. That does make you wonder why in light of feral dog predation being a thing in the real world, why aren’t there more anime and manga portraying dog girls doing the same thing? If farm cats exist in the real world, why aren’t there more catgirls working in farms for instance?
There are anime that do take inspiration from real life, all the better for it though I think there needs more of it if there’s ever a way to counteract the near overuse of moe stereotypes in anime. Again, basing characters after real life people more closely can lead to inspired personalities and character design choices. But the overreliance on the database can hinder it, thus it becomes little, if not nothing more, than a collection of tired cliches whether in personality or in appearance.
That’s where the grand narrative kicks in and turns out to have more advantages over the database model when it comes to constructing characters and stories, even though it’s not necessarily entirely free of stereotypes either. But I think with the database model, you’re more likely to be treated with characters created with stereotypes and cliches in mind as well as creating characters based off of stereotype casts. I do think that the database model’s limiting, especially in that it’s based on whatever stereotype’s around or popular at the moment.
There are anime that do subvert stereotypes or deconstruct them, but I think the best way to circumvent this is more closely portray anime characters after real people and things rather than being an assortment of stereotypes and cliches passed off as the real thing. That might be one of the problems with Fate/Stay, it’s a moe franchise where the characters who’re based off of real people are portrayed as an assortment of stereotypes and cliches that don’t make sense whether sartorially or story wise.
That’s why the database model of anime’s flawed.
