A Restless Night

10 years ago, Emily Black was subject to unimaginable amounts of pain at the hands of the Kouzo family.
Magnus Black was only a child, around 10 or 12, when he saw his sister dragged out of their home, breaking the peace, humiliated, tortured, and lastly killed. He didn't know any details of the killing, but he knew it was done by the well-known family of the Kouzous.
Upon finding out about their child whom they'd tried to keep secret, he vows to take what they took from him- the one he cared the most for.
