A Certain Demon Lord Strives to Live in a New World So He Won't Be Reincarnated Again

What?!

How did my big sister, the Demon King's daughter, become a hero?!

This is bad! The hero, who happens to be my sister, is about to cut down me, the newly appointed Demon King. What should I do?

Well, of course...

I'm done being the Demon King! I'll choose reincarnation!

The Demon King awakens in a new world after reincarnating, only to find herself surrounded by a crowd of burly men and girls?

Don't come any closer! I'm still a child!

How did I, a proper shut-in and great villainous Demon King, end up having to save the world and the girls?

Did something get mixed up here?!
