Sure, but if Godzilla came to my town asking for women to eat and then Zeus appeared, faced Godzilla and forced it to retreat and started "mating" in the middle of the street with a woman ( as Zeus was fond to to ) , I would find Zeus presence a tad strange as well, woman-eating Godzilla present or not
But seriously, the MC disguising as a woman and the absolute need of that ( with the added repeated failure of the MC to do so ) was a major plot point of this series up to the Sendorio arc. In the Sendorio arc the guardians there knew what men were, so there was no point on disguising. But we're back to a place where the women there think of men as mythological creatures of old and ... neither the MC or the Guardians with him consider disguising him ( even if to not fan even more panic ).
More, even the Guardians that didn't knew him were quite unfazed by the MC presence, something quite odd ( it is not that the MC existance and him being a man are common knowledge facts even among Guardians , as the 2nd arc of the story shows ... ). TBH , it looks more that the author forgot that he had to disguise the MC than anything else
