In a world where seven 'kings' exist, as the times change, the 'kings' also change, because no one and nothing is permanent.
The world is a big place, and even if such a person appears, as long as he does not get involved in the struggle between the 'kings', he will be just a passer-by around everyone.
Such a 'person', his name is——
Dresden.
Dresden is not human, even though he has a human-like body.
A pair of beautiful cat eyes, a head of seaweed-like dark blue waist-length hair, a beautiful face that never shows any expression, and barely visible blood-colored thin lips...
Is it a man?
Is it a woman?
No one knows...
