Demon King’s Royal Daughter

The princess born into the Kingdom of Astria will bring about the destruction of the world.

Born as a princess, I had to die in order to prevent the prophecy.

Thanks to my parents’ opposition, I barely survived and grew up showered with love... but in the end, I became the Demon King as foretold.

“Please, kill me. Don’t let me destroy the world any longer...!”

At the brink of destruction, in the world I had ruined, a sword pierced my chest as I begged to be killed.

It was Casiel’s sword, heir to the Holy Kingdom.

I thought that was the end of everything...

“Sera, if everyone in this world hates you, then Father will give you even greater love than that.”

“My beloved little sister. A world that hates you deserves to be destroyed.”

I went back to when my beloved father and brother were alive, when I was ten years old!

A second chance. I wanted to live quietly this time, really...

“I am Casiel Run Ertman.”

Casiel, the hero of the age who killed the Demon King.

He appeared before me and, instead of a sword, offered me flowers.

“Princess Seraphina, I want to become your fiancé.”
