After every trace of the Ultramen was erased and the legend of light was sealed away for good, monsters ran rampant, and humanity had long since forgotten the Giants of Light who once protected them.
Sun Xuan was just an ordinary boy who wanted a quiet life. But in a life-or-death moment as he tried to save someone, he conjured light with his bare hands and transformed into Ultraman Trigger.
After his first transformation, he was terrified of this sudden power.
Faced with disasters and difficult choices, he doubted he could shoulder the responsibility of a Giant.
But he was never fighting alone.
A memory-wiped intelligent AI named X, a transmigrator who knew every Ultraman storyline, and a gifted girl who could sense abnormal energy all journeyed with him.
Through each act of protection, every time they stood side by side, and every loss, the boy who had only wanted to protect himself learned to stand up for others, becoming a warrior of light willing to give his life to protect the world.
As the truth was gradually revealed, he finally understood.
The disappearance of the Ultraman era was not the end.
It was waiting for someone to bring the light back to the world.
This is the story of an ordinary boy who, in an age without light, reignites the age of light through his own efforts.
PS: The protagonist's world without Ultraman → X → Orb → Tiga → Trigger → Showa era
