@Demon123214 : There was a brief side-comment on one of the pages in one of the extra chapters that outright stated they were fake... but I point blank refuse to believe it. It is a completely unacceptable notion. Probably mistranslated, or a lie on the part of the adaption... or something. Basically there is no reason whatsoever for them to be fake, so I don't believe they are.
It somehow reminds me of the case of Sinon from Sword Art Online... and apparently her glasses are fake too, though apparently they're literally bullet-resistant, so she wears them like safety goggles... so I guess that passes. But then they also claimed she doesn't feel comfortable if she doesn't wear them, yet never wears them in-game... which is just stupid.
Anyway... I'm going completely off the rails there.
