The challenge of the Demon King

The Demon World became afflicted with a violent miasma, which caused havoc. With the staff of stars, the Demon King trapped the sick individuals in each hell. The Demon World's barrier was breached 200 years later, but this time the Demon King failed to shut it, even swallowing himself, and the Demon World descended into chaos once more. The new Demon World monarch has been chosen. The new monarch is the one who can re-seal the seven hells.
