The dead cannot speak.

It means the living can create any story they want.

Inheritance, honor and wealth can be taken away by lies.

However, what happens when a person, who was presumed to be dead, returns alive?

A young man who had longed for stories of good and evil since childhood lost his life in a tragic accident and was reincarnated as a boy named Chrono Mak in another world.

He learned that in this other world, there is magic and witchcraft, and depending on how you train them, you can become as strong as you want to be, so he decided to become the strongest demon king in order to recreate the story of justice and evil he once dreamed of.
