A being of light hailing from a faraway galaxy unites with Yuma, the protagonist who owns tremendous “power of imagination,” and they form the gigantic new Ultra Hero: Ultraman Arc.
Ultraman Blazar is a hero with a great sense of justice hailing from “M421,” an extragalactic astronomical object far from Earth. The main protagonist, Gento Hiruma, is the captain of the Special Kaiju Reaction Detachment (SKaRD), established by the Global Guardian Force (GGF) in a world where kaiju disasters are a common practice. When their strong desire for the power to save human lives resonates, the two unite.
Seven years have passed since Ultraman Trigger protected the world from various threats. In the present, Kanata Asumi, who is a positive young man, peacefully lives together with his grandpa. One day, while delivering ordered food, he witnessed a catastrophe: Spheres from the outer space attack Earth and Mars. Motivated by saving the precious lives of the people, he merges with Ultraman Decker and joins GUTS-Select, in order to protect what's important.
