Hatake Kakashi - Page 180

Kakashi is the sensei of Naruto, Sakura, and Sasuke. He is known as "the Copy Ninja Kakashi" or "Sharingan Kakashi" all over the world, and it is rumored that he has memorized over 1000 jutsu. At first glance you would never guess Kakashi is a very powerful jounin. He's very relaxed and sometimes even somewhat slow. He also loves to read his romantic (or is it dirty?) book "Come Come Paradise". However, in this case, appearances can be deceiving. Kakashi is known throughout the world as a formidable adversary and he was an apprentice of the Fourth Hokage, Namikaze Minato. He was also a part of the Konoha ANBU force, which he left for unknown reasons.

Kakashi is a very good but very strict teacher. Prior to Naruto's team, he had never allowed any of the teams he was to teach become genins. He uses the same teaching methods the Third and Fourth Hokages used, and he emphasizes teamwork above all else. He feels that someone who does not understand teamwork is not worthy of becoming a ninja.

Kakashi has the Sharingan implanted in his left eye. Not long after becoming a jounin, at the age of 13, Kakashi was assigned to lead his teammates, Uchiha Obito and Rin on a mission. During the mission Obito sacrificed himself to save Kakashi from being crushed by a falling boulder. That's when he told Rin to implant his Sharingan into Kakashi's left eye, because he knew that he would die anyway.
