How Kakashi Hatake in Naruto get his Sharingan?
if one of his eyes is how the Sharingan, and if we find later (after Naruto Shippuden 31 tell me because that is where I am)
there was a uchiha named Obito on your computer when it was part of the team Minato Namikaze, and when he got promoted to Jonin Kakashi his teammates gave him gifts and everyone had given him something that Obito. last in battle, Kakashi got his eye damaged and Obito was crushed. So before Obito deity, was the doctor of his team named Rin take Kakashi and give their eyes to replace his lost eye and said that was her gift to him in his honor to become Jonin. watch Kakashi Gaiden arc, explains everything.
