Librafeminine is a gender in which one is mostly agender but experiences a small amount of attachment to being feminine and/or have a connection with girl/womanhood. It's similar to demigirl, but is more specifically partially feminine and partially agender, with the agender part outweighing the feminine part, while demigirl is partially female, partially any other gender(s). Librafeminine people often identify as non-binary. If a librafeminine person is not assigned female at birth they might also consider themselves transfeminine.
The masculine equivalent is libramasculine, the non-binary equivalent is libranonbinary.
