Rule the world and kill the church. It is the mission of every demon king.
As time goes by, the strength of the demon kings and churches of the past generations has deteriorated further, and their strength is not even 10% of that of the first generation.
More than 400 years ago, the tenth Demon King... Uh... (Author: Can't think of anything, let's call him anonymous for now, haha), his strength is comparable to that of the first generation, and the strength of the church can no longer stop the Demon King from encroaching on the world. As a result, the traitor hidden in the demon army and the most trusted servant of the demon king, Hiss, rebelled. The devil is sleeping.

The devil wakes up as a rabbit... Nani?
