Ordinary people are in the galaxy. When they wake up, they find that they are in the world of "Ultraman Galaxy" and have become a new human body. Facing a familiar yet unfamiliar environment, as well as the heavy Galaxy Spark in his hand, he must learn to survive in this world. There are no scripts here, just real monsters and crises. How can he use this power that does not belong to him to protect the people around him and at the same time find the truth behind why he came here? This is not a hero show, but the struggle and growth of an ordinary person in a strange universe.
