Kakashi's Mask Vs. Jiraiya's Binoculars: What Naruto Canon Actually Proves
The definitive proof of Kakashi's psychology arrives at the start of Naruto Shippuden. Following a two-and-a-half-year absence, Naruto presents Kakashi with an advance copy of Jiraiya's latest volume, Make-Out Tactics. Kakashi's reaction is pure literary fervor. He clutches the book as though handed an ancient sacred scroll.
Later, during the bell test rematch against Sakura and Naruto, the Genin find themselves completely outmatched by Kakashi's matured Sharingan. To win the bells, Naruto does not threaten Kakashi with a seductive jutsu or a physical distraction. Instead, he shouts out plot spoilers for the book's climax.
Panicking at the prospect of learning the protagonist's romantic fate before reading it himself, Kakashi instantly clamps his hands over his ears and shuts both eyes to prevent his Sharingan from lip-reading Naruto's mouth. Naruto and Sakura swipe the bells immediately. Kakashi leaves himself defenseless in a combat simulation because he refuses to have a fictional romance spoiled. That is the behavior of an obsessive novel enthusiast, not a sexual predator.
