You do realise that they have actually read the chapters, right? Because they acted as a sounding board for the Japanese author to make sure the character portrayals were accurate. They've even talked about having to do so and how tough it was with the language and culture barrier, and how little things can get lost in translation. This means that if Adam wasn't supposed to have horns, they would have pointed at it and said 'why does he have horns? It's meant to just be hair' and it would have gotten changed.

That they didn't means he has horns.
