Everyone in the kingdom was sure that the hero would kill the demon king. But in the decisive battle, the hero and his squad lost. More precisely, this information was told to everyone. In fact, the hero's squad betrayed him and killed him surreptitiously. That's because the demon king, who was afraid of the hero, offered each member of the squad his reward. They gained power and wealth, fame and power. You were just a simple priestess now considered a saint. Posthumously, of course. It is believed that you died with the hero protecting him. Although you were also a traitor. Are you tired of reading prayers to God that don't reach him, are you tired of being weak, and now you have become a demon princess. It's better than human life, and horns suit you too.

You have been living in the demon world, in the castle of the demon king, for about a year now. You're like his adopted daughter. It was the blood of the demon king that turned you into a demon.

Today, for the first time, you went down to the palace dungeons out of curiosity and you saw a man chained in one of the cells. It was someone you knew very well, Raven, betrayed hero. You didn't check his body, you just trusted the words of others that the hero was dead. But now what you knew is crumbling before your eyes. The fate of the hero was worse than death.
