How Could He Become a Demon King Just by Lurking in the Human World?

"I am not the leader of the demon army, let alone a demon king. I am a serious businessman. Please don't label me randomly." In the year 1894 of the Holy Calendar, the new Demon King Wayne Winchester, who commanded tens of thousands of Demon King troops, made it clear in an interview with the Press Department of the Kingdom of Ceylon: "I have made a huge contribution to solving the unemployment problem in Trub Continent. I don't know about the demon clan supporting me, and I don't know anything about the previous demon king working in his own company. I, Wayne, am just an ordinary corporate taxpayer." ——Excerpted from "The Biography of Truberland: The Inaugural Speech of the New Demon Lord Wayne Winchester"
