I Was Reborn, but After the Villain Was Defeated

As one of the Demon King's mighty Four Heavenly Kings, she was determined to live and die alongside him. But the Hero easily sealed her throat with a single sword stroke, and she met her end.

When she woke again, she had been reborn as a girl, and the world she knew so well from her memories had changed beyond recognition.

Good grief, the human world is terrifying!

What is that iron monster speeding down the road?

Can humans really afford to eat such lavish meals now?

Faced with towering buildings that reach for the sky and a human world armed with powerful firearms,

the girl struggles to make a living in this new age, wondering whether the demon race still has any hope of rising again.

Humans are so scary.

Better eat a sandwich to calm my nerves.
