Naruto is one of the most popular anime and manga series of all time, so it is not surprising that it would receive a sequel series. Boruto follows a new generation of shinobi who grow up in a relatively peaceful ninja world. That being said, there are still conflicts and dangerous enemies to deal with. A number of good and evil Boruto characters have died in these conflicts, and a small number of Naruto characters have also died. Boruto's first manga chapter showed a destroyed Hidden Leaf Village, which led many fans to assume that either Naruto or Sasuke were dead, but they are both alive, at least for the time being.
