No not bio siblings . She has only 2 bio brothers as far as i know
I think they are cousins
they are her uncles and aunts siblings of Erno (he is 4th youngest son), no Nellia have more female features around waist and chest area but her metal fan (most likely a weapon) and muscles are supposed to point out that she might be physically strong not trans or crossdressing
so ur telling me all of those dudes r her siblings?? And is one of em like trans/crossdressing?? im so lost, esp cuz the dad looks younger than the oldest son and he doesnt seem as affectionate to the others…
