Kykosgender is a xenogender defined as a combination of mothgender and gauflux, where your gender feels like it matches the cycle of the day and night outside, and fluxuates with the intensity of the light.
For example duing the day you could be a boy and at night you could be a girl, but when it is darker, youre more likely to be demiboy or demigirl.
Dusk and dawn are the flux and demi gender times of the day. So you could say “when it is dawn, i feel like i am partially a girl and partially a boy” and vice versa.
