Is the '最高の女' (saikou no onna?) the thing that 'best girl' memes/terms are based on?


I'm kind of an anime/manga n00b, but I notice people on forums always talk
about like who is 'best girl' (or 'best boy' or 'best guy' Idk) in any
particular anime/manga series.

Then I noticed

  1. in this early episode of [Kaguya-sama](https://anime.meta.stackexchange.com/questions/4509/is-it-ok-to-overanalyze-an-anime) a character [Miyuki](https://japanese.stackexchange.com/questions/93903/whats-up-with-males-named-miyuki) says that Kaguya is, what I understood to be something like, 'saikou no onna'. Google translate suggests '最高の女', so I guess that's it. The subtitles however translate as 'ideal woman'.

  2. in this early episode of [The Quintessential Quintuplets](https://japanese.stackexchange.com/questions/93612/the-quintessential-quintuplets-aka-%E4%BA%94%E7%AD%89%E5%88%86%E3%81%AE%E8%8A%B1%E5%AB%81-is-%E5%B1%8A%E3%81%8F%E3%82%93%E3%81%A7%E3%81%99-it-reaches-a-mondegreen) the male protagonist Fuutarou calls the female protagonist Itsuki 'saikou' and then the subtitles translate as 'best' (as in 'You're the best.')

So it seems that when people say this term 'best girl', it is actually based
on some common Japanese term '最高の女' ? Please cite sources. I guess my google-
fu sucks (I just googled "最高の女" "best girl") or there aren't really any
primarily English articles that talk about this. Or maybe it just isn't the
case.




Let's take a look at the results for
[最高の女](https://twitter.com/SaikoSV?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor).
As you can see, they have little to do with fandom things; largely it's
articles for women to present themselves to potential romantic partners as
最高の女. And furthermore, I can't say I've particularly seen 最高の女 as a fandom
slang term either; this may be my own lack of knowledge as a non-native
speaker, but if I wanted to express the idea that a character is 'best boy' or
'best girl', I'd probably say リンタロウくん推し, 'Rintarou-kun is my _oshi_.'

What's more, fandom terms like this don't tend to transfer much between
cultures. An idea English-speakers express as 'waifu' (taken from an old anime
where a character called somebody 「マイワイフ」, I think) is 嫁｛よめ｝in Japanese, even
though the slight Japanese vibe to the English phrase might lead one to
believe that it would be the same.

Thus, because 最高の女 does not appear to be a fandom term and fandom terms don't
tend to transfer, I believe it's unlikely that 'best girl' originated as a
translation of 最高の女.
