I get that "the transfemme is masc" can be a really bad stereotype, and I wouldn't put that past the author, but I think Magne is kind of neat actually. I do not recall hullabaloo in-manga about her gender, she just sort of exists. Mostly outwardly masc, but long hair and she/her pronouns. I think seeing really atypical presentation respected in a fuckin Jump manga of all things is kind of neat. I can still remember the estrogenizing drag queen lady from One Piece's Impel Down arc, so yaknow. Progress?
