[Super strong male protagonist, no rebirth, no Virgin, no time travel, fight from beginning to end]
Don't wait for a hero to save the world! This "Devil King" is the terminator of darkness!
Alone, he swept across the world of crime; the underworld was uprooted by him, the human traffickers were eradicated by him, drug dealers, terrorists, dark syndicates... All the forces that dared to do evil could not escape his knife.
He killed a mountain of people, but they were all evil people who deserved to be killed; the evil people called him the "Devil King", but the people recognized him as the extremely righteous Dark Knight. What about fighting violence with violence? What can eliminate evil and bring peace is the "refreshment" that the world needs most!
