The Devil Goes to Save the World

"I'm going to save the world. While I'm away, don't let the demons and humans start a full-scale war." After the Demon King left these words, he left the Demon King's Castle and disappeared without a trace. The acting demon king Shuuer looked at the group of war elements under his men who wanted to rebel, and fell into deep thought. "I want to find something to do for these idle guys." Rioting prisoners, violent monsters, stolen artifacts, escaped saints... Acting Demon King: Are you still thinking about fighting? ! Do you know if there is a ghost in your home?
