– The world’s time will soon begin.

I possessed a third-rate extra villain character in my favorite game. I have no ambitions and I just want to live a quiet life. But sheesh, this world is a hard place to survive in. I will survive to the ending of this story, in a way the protagonist cannot. I will survive in the way of a third-rate villainous character.

After diligently following the “demon king’s standards,” I ended up getting killed by the heroes.

What, my tower and I are a custom-made hunting ground for heroes now?

With this chance at life regained through regression, to hell with the damn demon king’s standards!

This is the story of surviving as the hard-headed(?) demon king, Berje!
