There is such an interesting phenomenon for two-dimensional enthusiasts that everyone will be younger characters. Two-dimensional anime and games are basically indispensable to such a character image.
At that time, there was a "meng war" in Japan, that is, to select the most adorable (female) characters in the two-dimensional works, let's take a look at what the "meng king" of the past is:
The first moe king, Sakura Konomoto, from "Magic Card Girl Sakura", was set as a elementary school student at that time (the first part), and the age was 10 years old.
In 2005, The Moe King, Takamachi Naye, from "Magical Girl Naye", was also a elementary school student when he was (the first part)...
The sixth generation of Meng Wang, the ancient hand Pear Blossom, from "When the Cicadas Cry", looks like a primary school student.
Later, Japan's "Meng War" was not held, followed by the "Shi Meng Competition", and the Meng King selected by the 2011 Shi Meng Tournament was Misaka Mikoto from the "Catalogue of a Magical Forbidden Book"... Her setting is a 14-year-old junior high school student.
In recent years, in a popular mobile game called "Original God", there are also many girls who look like elementary school students, and according to the number of fan creations I have seen, they should also be more popular.
In fact, any time you look for a popular two-dimensional mobile game, there will be a female character with an effective appearance and age, which I think is completely designed to cater to the tastes of the market.
Why do young girls eat so well? I think it might start with the group itself.
In the 1980s, Japan's anime (anime, manga, etc.) industry had gradually emerged, but it had not yet formed a strong "otaku culture". However, in the early 1990s, Japan's economic bubble gradually burst, young people felt very confused, could not see their future, and because of the bad impact of the Miyazaki Incident in the late 1980s, Japanese anime could not look up at all in society.
In the context of such a wave of the times, the birth of animation such as "EVA", many people in the confused protagonist Yodo Shinji, as if to see the figure they want to escape, but also in some of the outstanding factors of this animation, Japanese young people began to like anime again.
In the 1970s and 1980s, it was said that Akihabara was just an ordinary street selling electrical appliances, but when those who liked to study electrical appliances gathered to play anime, Akihabara began to become a famous "two-dimensional anime street" in the 1990s.
In the mid-1990s, because of the phenomenal popularity of "EVA", Japan's otaku culture gradually came to the stage, of course, it could not reach the "mainstream" point, but just like the current "Devil's Blade" in Japan, adults and children are more likely to accept the form of anime.
And because of the EVA frenzy, I think that in the otaku culture that attracts men (not limited to men, of course), the female horn itself becomes a symbol of the otaku.
In the early 70s super Japanese animation, the male protagonist accounted for an overwhelming number, and in the 80s "Gundam" and "Chrono Fortress", although the status of female characters was also paid attention to, the male characters were still the protagonists of the story, but in the 90s, manga adaptations such as "Sailor Moon" were very popular. And later in works like "Magic Card Girl Sakura", the girl becoming the protagonist of the story has become a matter of course.
In the 21st century, there are even "selling cute fans" specifically to express the cuteness of girls, in which girls are assigned a variety of cute attributes, such as what is "natural stay", what is "arrogant", "mouthless", and the a-house people summarize various attributes to classify the girls they like. At this time, the status and importance of female characters have already occupied an overwhelming position in Japanese animation.
In Japanese anime, I like to describe the story of my student days, because the market audience itself is aimed at young people. The age setting of adults itself reduces the age-appropriateness of the story, for example, if the protagonist is a 40-year-old uncle, the taste of this work seems to have dissuaded a large number of young audiences, so the age setting is also for the sake of market demand itself.
In almost any fictional work, there is an element that "time does not change", of course, this does not apply to all works, such as "Magic Card Girl Sakura", the heroine will go to middle school with age. But don't forget the impact of "EVA" at that time, that is, "escapism", since girls are the youngest and cutest when they are young, and fictional works can keep their age unchanged, that is to say, in a few decades, the small pills I see will still be small pills, and the Conan I see is still a schoolboy... This kind of psychology still caters to ah zhao's wish... Of course, I'm not saying that Ah Zhao necessarily likes to escape from reality, but everyone always has this desire, "If... Well...", it just so happens that the composition of the two-dimensional otaku culture has just fulfilled the wishes of these A-houses, so it is not surprising that A-house likes young girls, especially girls in the student age.
In fact, most of the young girls in the second dimension have given the skin of a small child, and most of them have the logic of adults. Like the ancient hand Pear Blossom just mentioned, although her appearance is a primary school student, but because of the setting of reincarnation, her tone will even suddenly become an adult; like Kinomoto Sakura, no matter how powerful the enemy is encountered and how difficult she is, she can always calmly find a way to break through, and she is not like a child at all, so in the second dimension, young age is only appearance, and generally has the soul of an adult, because if even the soul is a child, the lines and behavior of the story will definitely appear more childish or unruly.
As for the otaku situation in Japan, why did it become like this in Japan? First of all, in the 90s, domestic television stations were broadcast with a variety of Japanese animation films, which had a profound impact on a generation; secondly, in fact, the aesthetics between China and Japan were still relatively close, so the image of Japanese comics was quickly accepted by the Chinese people; moreover, now games like "Hara God" have basically achieved reverse output, and many Japanese mobile game broadcasters also like to play "Original God", so when designing characters, considering the aesthetics of Japanese comics, they will also do these cute little girls.
From the impression point of view, young girls also mean naïve, lively, ignorant, with the growth of age, even if they are not the age of the anime, they will miss the girls of the student era, when the simple girls are really completely different from the women in the office. Therefore, the young girls in the anime often make A-house yearn.
