Kakashi is an easygoing person and the leader of Team 7. He is also the teacher of Naruto, Sasuke, and Sakura. As the leader, he treats his leadership position with a detached manner, and he is consistently late for meetings. In the Kakashi's past story, this is shown to be the result of an incident in which he witnessed the death of one of his teammates, Obito Uchiha, who gave Kakashi his Sharingan eye and imparted many of his habits, including his tardiness. With Obito's Sharingan, Kakashi has amassed a reputation as a skilled and powerful ninja, earning the moniker "Copy Ninja Kakashi". Kakashi concentrates on training and teaching Sasuke; however, he is unable to prevent Sasuke from leaving the village to seek Orochimaru for greater.
