yeah, that genuinely came out of nowhereWait a minute they're cousins? I might drop this series.
3rd degree kin is first cousins.3rd cousin marriage is banned in Japan? Banning 1st is bare mininum for health, second cousin marriage is genetically good for genepools but possibly tragic for individuals, but extending 3rd is a little odd.
Maybe they want to dissuade clans from forming and maintaining?
I guess it's more of a paid vacationYou get an allowance at work in Japan for being married?
