The Remaining Ninja

Many years have passed since the death of the hero and Hokage Naruto and his peers and the vanishing of a tailed beast. The world of ninja and samurai maintained its peace and prosperity to the point where wars and tailed beast became legends and myths. So peaceful that people began to stop practicing ninjutsu. For generation. The five nations lived together in harmony. Then, everything changed when the westerners attacked. Only the Kages of each nation and the army of the strong ninja could stop them. But when the world needed them most, they vanished. 100 years have passed and the westerners are nearing victory on their conquest. A new generation of ninja was formed. Even though their skills are great, they have a lot to learn before they could stop the invasion.
