I was the almighty Demon King, feared across the world, ruling with absolute power… until those pesky heroes finally managed to kill me. But instead of eternal rest or a glorious resurrection, I got something much worse—reincarnated as a Saintess?! Now, I’m stuck in the body of a delicate blonde girl, worshipped by the very humans I once tried to destroy. They expect me to perform miracles, heal the sick, and act all pure and holy?! Yeah, right. To make things worse, my own demonic armies are still out there, causing chaos, and if they ever find out their great and powerful Demon King is now some dainty saintess… well, let’s just say I’d rather not die twice. Can I survive this ridiculous second life? Or will I end up saving humanity by accident? Either way, this must be some kind of sick joke!
