Kafin is a gender label that does not fit into any gender structure (such as the binary structure), lack of gender structure (abinary and others) or outside of that gender structure (non-binary) and therefore can only be described by one's personal state of being or personality. This gender can be considered fluid due to changing states of being or plurality (if all share one gender).
Singular is Kafin(Ka-fin) and the plural is Kafine(Kah-fien) . The gendered symbol for kafin is 0÷(Zero Division). Zero Division is used to mean the division of kafine gender experiences (0) to gender structure(any number). Since you cannot divide by zero, you cannot get a gender that fits into the gender structure and therefore kafin gender experiences can fit into any category while also not being in that category. Meaning a kafin can fit into mlm/wlw/nbylnby/ala without being that specific gender.
Kafin is an inclusive label for all who lack a gender, don't feel represented by gender or need a gender. Agender implies that one can experience gender, just not have any connection or need for gender (like how some asexuals experience sexual feelings, they just don't have sexual attraction)
Kafin vs. Agender and Gendervoid
Kafin is very different from agender or gendervoid because both of those terms are in the non-binary umbrella as they don't fit into the binary but Kafin doesn't fit in non-binary, abinary, binary, trinary, atrinary, nontrinary or any other gender structure.
Kafin is not the lack of gender but the lack of a universal gender experience while agender is the lack of gender connection or lack of need for gender.
