Kakashi Hatake はたけカカシ

Kakashi Hatake is a shinobi of Konohagakure's Hatake clan. Famed as Kakashi of the Sharingan and the Copy Ninja, he is one of Konoha's most talented ninjas, regularly looked to for advice and leadership despite his personal dislike of responsibility.

Kakashi has an ongoing, albeit slightly one-sided, rivalry with Might Guy, with Guy constantly proclaiming that Kakashi is his rival, and considering his and Kakashi's subordinates rivals. Kakashi, however, seems indifferent to their rivalry, which annoys Guy to no end.

Though he evasively says that he has "many hobbies" when asked about himself, he is commonly seen reading of "Icha Icha Paradise" (literally "Make Out Paradise"), an adult and probably pornographic novel that is a runaway bestseller in the Naruto world. Kakashi most prominently reads it while training and speaking with his team, and is later seen reading the second known volume in the series, "Icha Icha Violence" (literally "Make Out Violence").
