it's the translator editing and erasing her boob line so it end up making it look all weird. I've seen people do this on other series
yeah I've seen that sort of nonsense before too, but that's not the case here. Even from the side, she's flat as a board while Diane (water spirit) has huge, bubbly boobs with plenty of unerased cleavage
on the series cover and in the first couple chaps she was like a C or possibly D cup... and now she's barely an A. I feel like Diane showed up and the author was like "we can't have two characters with tits, the readers won't be able to tell them apart".
