Demon King In Distress!!!
It was the Demon King who traveled to the world of humans with the Four Kings of Heaven.
The destination he reached was the solitary island in the middle of the ocean.
On the island where magic cannot be used, a survival that can laugh backwards, with the sadness of the rulers and subordinates in the Makai begins!
The devil that loses his magical power in the fight fulfills the principle of the of the human soul and its power!
