After the global monster disaster, the world established the Earth Defense Force (GGF) in 1966 to deal with the attacks of monsters and alien life from inside and outside the earth. Today, human destruction of nature and global warming are becoming increasingly serious. One night, the space shell monster Bazanjia appeared. The cleanup operation of the Earth Defense Force encountered difficulties, and the special forces led by Hiruma Gento fell into a desperate situation. At this time, a mysterious giant descended with a dazzling light. This is an unidentified large alien codenamed "Ultraman", and there have been rumors about him among astronauts for decades. Later, Gento was summoned to the command center and suddenly received a task to become the commander of the Special Monster Response Detachment (SKaRD). SKaRD is a special monster response detachment of a secret organization. This special force he commanded mainly drives the giant monster-shaped robot Asgalon to fight against the monster disaster. At the same time, he was also ordered to investigate whether Ultraman, who appeared in the battle of Bazanjia, is an enemy that must be eliminated. "I'll solve it." Now, under the light of Ultraman Blaze, Captain Stringer will join the special members of the newly organized SKaRD in a new battle against monsters, with solid courage and firm justice hidden in his heart!
