A child who lost everything to a villain. Ten years later, that child returned as a hero called a demigod. And the enraged hero began his revenge by killing the villain and his family… But there was a problem. It was that Lila was the daughter of that villain. “Are you Lila Hildegar?” “You've got the wrong person.” “No, I think I've got the right one.” …Pretending to be someone else, failed! “Please spare me.” “No.” …Begging for her life also failed! There was no other choice. Lila chose the last resort. “Any last words?” It was to swallow the “Regression Stone” and return to the past after death. “It wasn't pleasant meeting you, so let's never see each other again!” That's how Lila returned to the past, opened her eyes at the age of ten, and… Died again. Lila tried to survive. She tried and tried again. That was all she did… “Why did you save me?” The boy answered with a pale face. “Because I've gone mad.” …The enemy who had driven Lila to death several times became strange.
