The Gosei Angels are beings who have secretly defended life on Earth for thousands of years, lead by Master Head. While human in appearance, they are usually not seen as they move among us. The road between Earth and Gosei World is Heaven’s Tower- a massive structure which hangs upside down from the clouds. Unfortunately, an empire of aliens, called Warstar, has chosen Earth as their next target, and they have destroyed the Heaven’s Tower in a preemptive strike! Now isolated on Earth, five Gosei Angels-in-training must learn to cooperate with each other, and bring the powers of their three tribes- Skick, Landick, & Seaick- together in order to defeat Warstar, as the Tensou Sentai Goseiger!
