Vilmia is a demon, and the Demon King. In short, she's a proper, old-fashioned Demon King: one who tramples all living things, sets everything ablaze, and reduces the world to dust beneath her feet.
Unlike those giants who talk big but never act, Vilmia really did what her colleagues couldn't. She slaughtered all living things, slew the gods, and consigned the world to the flames of the past.
But before she could enjoy even a moment of the fruits of victory, she kicked the bucket in an interstellar traffic accident. Fortunately, the culprit didn't flee the scene and took full responsibility.
And so the Demon King died, and a girl was reborn. Her current job: savior of the world.
"Vilmia, stop muttering to yourself and think of something!"
"Coming, coming! Watch me do a jumping slash!"
The Demon King is working overtime to save the world again today.
(Though it's categorized as fantasy, it's actually more like sci-fi... A very amateurish imitation of those giant eyeballs.)
