On an Earth where neither heroes nor kaiju exist, an alien suddenly falls from the sky. This Ultra's symbol is the red space boomerang he holds, the Omega Slugger, and his name means "ultimate." "Omega" is an alien who has lost his memories. Taking human form and adopting the name "Sorato", he becomes interested in the life forms called "Earthlings" that he is encountering for the first time and attempts to understand them. When a giant life form appears, amnesiac Sorato recalls a word-"kaiju". As these kaiju continue to appear before him, a sense of duty awakens in Sorato's subconscious. He transforms into "Ultraman Omega" and an intense, fast-paced fight unfolds. The Earthlings, in turn, are grappling with encountering these gigantic life forms and the alien that fights with a red slugger for the first time, watching from various places and trying to understand what they are. Before long, Sorato and an ordinary young man-an alien and an Earthling, become friends. This ambitious work poses a question through these friends' resonating hearts; "Why does Ultraman protect the Earth?" Now, is when they awaken.

In a town called Hoshimoto City.. A giant object towers in Mt. Shishio. Named "Monohorn", it is actually a kaiju's horn stuck in the ground since an incident 16 years ago.

The incident when kaiju appeared simultaneously around the world was later named "K-Day". Since then, the Global Defense Force (GDF) has been dealing with kaiju with force, while SKIP (Scientific Kaiju Investigation and Prevention center) works closely with the community in scientific investigations and evacuation guidance to prevent the occurrence and aggravation of kaiju disasters. SKIP has also been investigating the Monohorn, the horn of the galactic beast Monogelos, which appeared on K-Day.

Yuma, then only 7 years old, was camping with his parents in Mt. Shishio when Monogelos attacked, but somehow miraculously survived unhurt. This experience led him to pursue the path of kaiju biology research, and despite his traumatic past, he has not lost his "imagination" to dream. As a rookie investigator, Yuma joined SKIP and was assigned to the Hoshimoto City Branch.

Not long after, another large-scale kaiju disaster occurs. As Yuma sees the desperate people in front of him, a strong will springs into his mind — "I want to protect them!" It was at that moment when Yuma hears the voice of Rution, the being of light that he once saw as a child: "You and I are one and the same… Unleash your imagination!"

When the mystic light emerging from Yuma's hand embodies his entire body, his power of imagination fuses him with the light and he transforms into Ultraman Arc, the Giant of Light who protects the future! Alongside his precious friends, Yuma, as well as Ultraman Arc, gallops towards his everlasting dream!

It is the unidentified humanoid alien that has been rumored among astronauts for decades, code-named "Ultraman".

Later, Gento is summoned to the command center, where he is officially appointed as the commander of SKaRD, short for Special Kaiju Reaction Detachment, a team that had been secretly formed.
