Blazar and SKaRD face defeat in their battle against Varallon on the moon. Meanwhile, Emi is captured by Dobashi. In a dire turn of events, Varallon descends to Earth. Adding to the mystery, there's an appearance of a mysterious fleet of messengers. What will be the fate of SKaRD and Earth Garon's battle? What truth does Emi discover? Will Gento and Blazar be able to protect Earth?
Varallon reaches the moon, dropping bombs one after another. If this persists, it will alter the moon's orbit, leading to catastrophic consequences for Earth. Command directs SKaRD to deploy to the moon in the Earth Garon Mod.4 to eliminate Varallon. A desperate space battle unfolds.
Everyone who looked into the big hole went into a state of confusion. During the investigation, even Teruaki, Anri, and Yasunobu fall victim to this strange phenomenon. Emi boards the Earth Garon alone and will challenge the kaiju, Mogusion, with help from the voice interactive AI system, EGOISS.
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.
