How could the hands of fate be so cruel to us?

It was said in a legend that a final battle between blood would change everything and cause chaos throughout.

In forgotten time, the Ten Commandments who were the personal guards for god, won the battle against the undead for peace, though both heaven and hell were in ruins for what was already there to begin with. Lucy, who was one of the Ten Commandments, went down to the human realm to live among as one of them, though without knowing that the string of fate connected her with a human man, a man apart of a cult no less.

Years went by before they had two kids, both girls, the eldest one inherited her mother's power while the younger one inherited something sinister from her father.

But even so, no one knew what the twisted hands of fate had in store for the sisters.
