[Fictional world + no System + coming-of-age protagonist + new Ultraman + single heroine]
This is a world where [Ultraman] exists only as a tokusatsu show.
The warriors of light, symbols of justice, lend humanity a hand when monsters and aliens invade, saving people from danger time and again.
Until that rainy night.
Huang Chengming, a 29-year-old office worker whose youthful passion has long since faded, encounters a bizarre phenomenon.
A sudden blackout in the middle of the night. A neighbor's screams. Monsters capable of twisting themselves into the likeness of other people begin attacking humanity.
A warped barrier. A grotesque giant. At a critical moment, a beam of light appears.
When the light known as [Kongyou] shines upon Huang Chengming, will he be afraid, afraid that he, too, might become a monster just as terrifying?
A new chapter begins here.
(A friendly reminder: This story leans toward episodic arcs. Other than the protagonist Kongyou, all Ultramen are impostors and do not represent their true forms, unless the author explicitly says otherwise. Kongyou is an original Ultraman created by the author, and the story offers reasonably thorough explanations for the related worldbuilding. The romance between the leads is not the focus, so you can read it as either a single-heroine or no-heroine story.)
