The Regressed Demon Lord Is Kind

Zich Moore, the fearsome Demon Lord, is struck down by the hero Glen Zenard. As he dies, he hears Glen's request: for him to be a good person if he is ever reborn. Miraculously, Zich awakens in the body of his younger self and resolves to be a better individual. But the problem is... he has no idea what it means to be good! Can the former Demon Lord truly learn what it means to be kind? Or will his old habits and misconceptions about virtue and goodness make redemption difficult?
