Ling Ye, the last observer of high-dimensional civilization, fell to the earth with fragments of the origin of the universe and awakened as the silver and black Ultraman Starfall. He devoured monster energy and showed no mercy to his enemies - he even leveled half a factory to prevent the Zeton larvae from destroying the city; to seize the plasma spark fragments, he beat Zero's Plasma Spark Slash.
When Max's "guarding" collided with his "killing", when Mebius's "light" met his "darkness", when Zero and Zedd wavered in their definition of justice because of him, a storm of ideas suddenly set off across the Kingdom of Light and the Earth. The "Cosmic Devourers" lurking behind the scenes are approaching following the trajectory of Ultra's Light - they have devoured high-dimensional civilization, and their next target is the entire unbalanced universe.
He is the "alien" that the Kingdom of Light fears, but he is the last "balancer" on earth. In the gap between killing and protecting, the ultimate answer to the survival of the universe is hidden in the light of the fallen star fragments.
