Angel with a Sniper[First Draft]

Sienna was only 18 when she escaped from her past and disappeared into the sea that is Nekoma city to join the ranks of the irreverent Deathwatchers while trying to learn about being a new vampire.
As the member or the elite force she spent the next three years making sure people met their fates when the time came because each soul must be saved at any cost, and those who miss their deadlines faced an even worse fate than death.
Meanwhile, the evils of her past life come haunting her and push her in the path of a drummer Hinata, who seems to be the target of the same forces that once took away everything she had, led by a centuries old vampire lord - Alexander Ashworth.
Now Sienna must face what she has become and understand just how much she is really willing to sacrifice and what really comes first, her own freedom or the souls of the innocent.
