All of the Ultramen and monsters have been turned into figures known as Spark Dolls and became scattered throughout the universe. A young man named Hikaru Raido finds an item called the Ginga Spark which not only allows him to become Ultraman Ginga, but also allows him to Ultraive with the figures to change them to their rightful size and become one with them.
