Birth defects only happens in 1° level cousins.
In Japan and many other countries it is normal for the families to be big to the point of having 6° and 7° level cousins, where there is almost 0 dna in commune.
are they lvl 1 cousins???
From what I get from the story I'm going to say no.
Normally this type of arrangements are done between very distant relatives.
And in manga if they are very close in family...it's like the 1° thing they talk about xD
╮(￣▽￣)╭
In some parts of Japan, 16 is a legal age for marriage(female) and they mentioned about waiting for her to turn 16
I really want Rio to marry Nagi tho ;-;
It’s actually totally legal for cousins to marry. Incest classifies as sexual relations between immediate family, aka siblings or parent/child.
there are two sisters, one ran away and the second is too young so they didnt even consider the option
Not totally true. A much higher probability, yes, but you can't say "only"
none of this matters actually coz in the end it's allllll Nagi
But in their families they didn't have any problem regarding that...?
They're fcking cousins?!?! even Nagi's sister is fcking underage, like wtf is this even legal, then how...also if they're cousins then their babies are gonna be so disabled and retarded bc of genetic mutation and 2nd Rio is gonna get arrested if he marries Nagi's sister
