Just watch it be Nasa
As a fan who has a soft spot for the cute, sleepy dragon who lives in the mountains of Japan and grew up around her boar-hunting grandfather, I would happily take Nasa as the top hag. However, I'm still leaning more Iori as top hag, but that's not saying Nasa isn't a hag or almost-hag.
It wouldn't be the first time Airi shares something she wasn't supposed to when talking casually and other members have said it before she and fishman are alike in that regard. I have not watched a single hour of iori to debunk the claim but my money is still on nasa. She was playing ps2 games on the original hardware some weeks ago and even though she would have to do it since she is in japan, how many zoomers would be willing to play ps2 games in this day and age? specially when they need to run the original hardware.
