That's ... not really relevant to the question. The question was if Naotsugu knew that Tet's a man in real life (since he seems oblivious whereas almost everyone else is aware of this).

Sure, he probably accepts that people in opposite gender bodies are now "matching" those bodies, but that doesn't affect the question of whether he's aware that Tet is one of those people or not.
