Season 1

Curious about the Planet Arb, the being later known as Ultraman Hikari flies down to the surface. The people of Arb sense the pureness of his heart, and materialize before him. They explain that their peace will soon be disrupted, if the prophecy of Tsurugi is correct.

Shortly after his time on Earth, Hikari is flying through space. He is suddenly attacked by a Bemstar, and forces it onto an asteroid below.

After the events of the last chapter, Hikari appears before Father of Ultra, Mother of Ultra and Zoffy. He asks to be assigned to Earth, and after persuasion from Zoffy, Father agrees.
