Looking at Miyako, the assistant named Brendan would see what looked like a mostly normal woman, the only thing that didn't exactly look normal being her red eyes and white hair, though both could easily be explained by mundane methods. Other than this, she was somewhat tall, had long hair, was wearing red and white clothing that looked somewhat traditional and certainly comfortable, and lastly, interestingly enough, had a few visible scars. If he payed particularly close attention he might see that she had something hidden on her person, that being her tonfa, but chances are he wouldn't notice it.
Still what he said helped to some extent. It confirmed that her assumption was true, but unfortunately whether or not they were actually taken here or were just acting was still up in the air at this point, and worse he was leaving now with all the others. At the very least if this was a trap they would be the ones to walk right into it instead of her, which would allow her to have an advantage and attack from behind if it was an ambush, free the others if it was a non lethal trap made to capture them, or at least not die if it was something like a mine field. Though that could be just what they wanted, relying on using her own natural distrust against her...
Either way she would follow the others to the park from a distance all the while being on guard.
