A noble ‘hero’ who punishes evil under the protection of the gods. A powerful demon who is the last survivor of a powerful demon tribe, born with the power of the devil, the ‘Demon King’. A skilled third-rate ‘villain’ who leads an evil organization. My life as a villain is now over, but when I tried to retire and live a comfortable life, I accidentally picked up the Demon King. And now, the hero has come to repay me. This is just ruining my comfortable retirement life! To the 99 demons protecting the villains… May God bless you and die!
