In the final episode, the master of darkness, Dark Lugiel reveals himself. Alien Nackle drops a clue that the wielder of darkness resides in their very elementary school. Hikaru fights with his friends to uncover the darkness behind the Spark Dolls. A young man named Hikaru Raido eventually stumbles across an item called the Ginga Spark (ギンガスパーク Ginga Supāku), the same wielded by the Ultraman, it not only allows him to become Ultraman Ginga, but also allows him to go Ultlive (ウルトライブ Urutoraibu) with the figures to change them to their rightful size and become one with them. Ultimately he lost, and his item fell to Earth with his Spark Doll within it. In response, an Ultraman named Ginga appeared with a similar item wielded by the dark elusive figure and fought him. With it he transformed all the combatants into figurines called Spark Dolls (スパークドール Supāku Dōru). During this great conflict an unknown being appeared wielding an object of great dark power called the Dark Spark.
