Once there was a “Giant of Light” that defended world peace from the threat of giant monsters and alien invasions. His name was Ultraman. Time has now passed since he completed his mission, in which he bonded with scientific investigation team member Shin Hayata, and departed the Earth. During this time humanity welcomed an age of prosperity. But it was no more than just the illusion of peace… Now, when the world once again needs the power of a “Giant of Light,” a new hero emerges who has inherited the genetic factor of light. But he is no giant. He is a normal-sized troubled high school student, clad in a metallic powered suit. His name is Shinjiro Hayata. A new story unfolds as the son of Shin Hayata, the man who was once Ultraman, struggles to become the Ultraman of a new generation.
