Okay first off notice the use of the word 'theory' this is not truth and 당신 can believe what 당신 want of it this is just my opinion.
KuroYuri is first off in the army we have only seen one femael in the army so far out of tons we have seen, this makes it likely he is a boy.
KuroYuri got into the church to take the bishop's exams as far as i know bishops can only be boys. This further supports why 당신 see no female test takers and also why 당신 see no bishops that are female, although in the 아니메 i did see a few ponytails but they could have been guys since i couldnt see there face's.
KuroYuri displays 더 많이 of a boyish personality then a girlish one, sure he has 담홍색, 핑크 hair but really, in the 아니메 world 당신 can have whatever kind of hair 당신 want lol.
