Togashi seems to be pretty savvy on this gender thing and the pages look accurate so far. In the works, Kalluto's gender is unconfirmed but most males who crossdress identify as male, and Alluka is confirmed to be of female gender by Killua. They are still both young but I assume Togashi is making a point on gender expression here.
