Also, since when is "Ryuujou" a trait? (lol) I guess it's a good thing that someone else also said "flat-chest" rather than "oppai loli", or she might have wound up with one large and one small breast, like the divided hair.
I had to google what "エロフ" meant and it led me to the pixiv encyclopedia entry. It described as being Elf Erotica or an Erotic Elf. I had to translate that somehow.
