@Aricitic Or maybe the intent was to make her act sympathetic so she wouldn't offend the heroes she had intended to send, instead of dissing 'em like she did Makoto just because he wasn't up to her standards of beauty?
Basically I think the intent was that she, the Goddess, chose to act good towards the heroes she wanted while hiding her true self. Or, that it was the intention of the author and/or artist to do so (no clue if they're collaborating or if the artist is just bringing the visuals to the WN/LN or whatever it's based on).
