After the Ninja World War, the Otsutsuki clan outside the world realized the value of the "Ninja Planet". The power of such a sacred tree was a miracle that had only appeared "once" in the hundreds of thousands of years since the birth of their clan. From then on, the Otsutsuki clan began to send tribesmen to lead "war beasts" to start the invasion of the ninja world...
Shadow Weaver is a young man with the ability to control shadows and weave dreams. His true identity is Uchiha Madara's younger brother, Uchiha Izuna. He wanders between the shadow world and the real world all year round, and is an important messenger conveying information from the outside world to the shadow world.
In order to fight against the power of the Otsutsuki clan, Shadow Weaver decided to join forces with the ninjas of Konoha Village. They went deep into the Shadow Realm, eliminated the 'Beasts', fought against the Otsutsuki clan who invaded the Shadow Realm, and searched for the key to defeating the Otsutsuki clan - the imprisoned 'Shadow Master'. In the process, Shadow Weaver and his partners established deeper trust and friendship.
On the final battlefield to rescue the 'Shadow Master', Shadow Weaver and others started a fierce battle with Otsutsuki's tribe. He used his ability to control shadows and weave dreams to create illusions one after another to confuse his opponents. He eventually found the opponent's weaknesses and defeated them in one fell swoop, and was eventually elected as the new leader of the Hokage world.
