Darkness overflows silently like a tide, hiding in the corners of modern civilization, eating away at people's hearts and lives in the form of alien beasts. What confronts him is a light inherited from ancient times—Ultraman Nexus.
However, this light needs a carrier, and it needs capable people from generation to generation who can still hope in despair. They are warriors chosen and cursed by fate. They transform, fight and suffer scars alone on unknown battlefields. Each pioneer is like a bird flying towards the flame, using life as fuel and burning himself out, just to let the light last one more moment and illuminate one more inch of the way for those who follow.
Their sacrifice is not the end. All the battles, tears and shouts have turned into a heavy will and a more powerful legacy of light, waiting for the final person to inherit.
When the final darkness falls, who will be the heir to that legacy? Can he bear the thoughts and prayers of all the deceased and temper this weak and swaying light into the ultimate light that can break through the eternal night and usher in the dawn?
