When the wild light from M421 and the man carrying the power of the monster met on another earth——
This is a time and space that is both familiar and unfamiliar. The space monster "Bazin A" tears apart the Tokyo night sky, marking a new stage in the war between mankind and extraterrestrial threats. In this turbulent world, two beings with inhuman powers quietly walked to the intersection of destiny.
Genito Ichikawa, the 22-year-old captain of the third unit of the Earth Defense Force (GGFJ), is a calm and decisive young commander. In an accident four years ago, he merged with Ultraman Blaze, a life form of wild light from M421. Since then, he has been burdened with a dual identity and the pain of symbiosis that tears his soul. His battle is not a divine salvation, but a struggle, negotiation and dance with the starry beast within him - every transformation is a battle between will and wildness.
In the shadow of GGFJ, the special monster corresponding mobile team SKaRD was quietly established. Among them, there is another secret hidden: the ace team member Shinomiya Emi, an elegant and capable genius intelligence officer; and the man she silently guards, who can transform into Monster No. 8 - The former cleanup team member Kaido Shinji. He is both human and monster, torn between self-loathing and the belief in protecting others.
