was watching a video on naruto facts and one of the facts is that Kakashi's mother is a descendant of the Inuzuka clan, which would explain his dog summoning contract. if this is true this would make Kiba and Kakashi distant cousins. does anyone know if this is true. and if it is where does it say this? does it say it in the databooks
