Clans

[SenseiSama]

Did Kishi ever imply or mention in any interview whether clans were inbred ? None of the members seemed retarded.. In my opinion they aren't and the only inbreeding that occurs is possibly the use of distant cousins

 

[Naruto X Hunter]

He never said anything about interbreeding as far as i know.Clans doing that is just fan speculation.

 

[Kaneki Kun]

Different universe, not everything that happens to us happens to them.

 

[BenjerminGaye]

They obviously are.

keeping the royal bloodline pure is gotta be nasty
