Title : The Regressed Demon Lord Is Kind
Synopsis : “Demon lord Zeke Mohr, be someone who does good in your next life!”
The hero shouted at the 'Demon King of Power', Zeke, who met his death.

When he opened his eyes, he realized that he had returned to being Zeke Steelwill, before he became the demon king.
In this life, he had no desire to become the successor or Demon King.

"So what? That's right! Maybe I will do “good” as the hero said!”
But, how does he do it? The former Demon King wasn't used to the concept of "kindness".
