Naruto and Boruto are very different shows, but one dark Shippuden theory explains why. As was expected, Naruto’s ending was followed by the beginning of a brand-new series, Boruto. Though a few of the sequel series' characters were introduced in the very last chapter of Naruto, those characters didn't get room to breathe until Boruto: Naruto the Movie, one of the two canon Naruto films. Boruto takes place 15 years after the end of Naruto Shippuden’s Fourth Great Ninja War, in a peaceful world where neither the Akatsuki nor the tailed beasts are a problem. However, one dark theory suggests all of Boruto might be a lie.
