Is there anyone left out there who didn't hear of Naruto? If the answer is "no," it will be difficult to believe. If we all know about Naruto, surely not the same can be said about Boruto, especially for those who didn't follow the series.
Boruto is Naruto's son - and now surely the mystery is over. However, the story is not over. Even if Naruto managed to accomplish his dream of becoming the greatest ninja in his village and everyone can see his fave atop the Hokage monument, the same can't be said about his son.
Boruto leads a new and young generation of ninjas. His hobby is to play videogames all day and not train, but he does have a secret desire: to become stronger than his father, and to defeat him.
