The Regressed Demon Lord Is Kind (Novel)

My whole life, all I wanted was power. I churned the world into rivers of blood and eventually gained the title, "Demon Lord of Strength." However, all this became useless when I lost to a party of heroes. As I laid dying, I was forced to listen to the hero's gibberish: "If you are born again, I hope that you will live a kind life!" When I opened my eyes again, I was back in the past. This is the beginning of an ex-Demon Lord’s journey to live a kind life. **Original Novel:** , , **Official Translations:** English:.
