Naruto returns from three years in the future to a time three years earlier. Already invincible, he becomes even more so. But the once honest and good-natured Naruto has long since become lecherous and flirtatious after all sorts of mishaps. He travels to the future to gather intelligence, then goes back to the past to change the future. In short, he can travel through time wherever he pleases. The age of the Flying Thunder God is your age, Naruto's age, everyone's age!
