Five years ago, her school was destroyed, and she took her junior brothers and junior sisters on a bloody road of revenge that she would never look back on.
Five years later, her former junior brother was already an emperor above all others, and she willingly became a sharp blade in the dark night.

Until the truth came to light, the innocent and lovely junior brother asked her with a smile:
"Sister, do you want to kill me too?"
