Be they human or demon, most believe that all members of the dragon race can transform into their original forms.
That assumption isn't entirely wrong—but it isn't entirely right either.
Since the victory of the all-race alliance army seven thousand years ago, the number of dragons has drastically decreased, becoming a fraction of what it was before the Evil God descended into the world.
To prevent extinction, the Dragon Ancestor took mates from various dragon subraces—and the strategy proved effective.
Today, the dragon population has stabilized and is no longer at risk of extinction.
However, with peace firmly established and no more wars to fight, most dragons have chosen to live in humanoid forms, as their original forms are large and impractical for daily life.
This shift didn't stop with the first few generations—it continued steadily for seven thousand years.
As a result, many lost the ability to return to their true forms.
