I have a lot.. so I'm gonna do what Illya did and list ones with specific ones!

Trans women - Miyu, Poppy, Kwanghee, Alexandria, Tina

Trans men - Ryuu, Tristan, Kazuki, Lawrence, Kasun, Javier, Yijun, Faine, Francis, Mercury, Leo, Clyde

X-gender - Ryuu (Masc leaning)

genderfluid - Samara, Beta.

other - Giza (Born intersex-pais, raised female, has more-so transitioned into a trans man, but he is uncaring of what pronouns you use for him.) Zesha (Uncaring, but born male and leans into it. he's just zesha.)

? - Lucia identifies as female as she was raised as that by Vasil's choice. However, she has both breasts, a uterus a penis. She is able to get pregnant, but due to lacking the right parts to really... get the baby out, she miscarries every single time. She suffers from ghost period cramps but that is mainly it.

Lucia has no true connection to her gender and would have went by whatever Vasil raised her as, however most demon/angel couples tend to lean into raising their children depending on their sex. Vasil is an odd case of this because he wanted a daughter.

In New York, if anyone is ever capable of seeing Lucia naked- they tend to assume she is a trans woman, but she isn't. she doesn't identify as that. She was raised female and that's that.

Damuth - Damuth was created by The Mother as a more so genderless type being, he has the equivalent of Intersex - Pais condition, but was raised to choose whatever he identified as. Keep in mind this is far back in the past, before these types of questions were truly asked. Damuth identifies as male, more or less.
