Valentine

Valentine got caught up on some pretty bad stuff when she found out her old partner got killed in a so-called accident. With his death she discovered he worked for a crime oranization called Talon and that all his debt with the place got transferred to Valentine, she found herself being forced to accept the job, until she gathers enough money to clear the debt and finally be able to move on.

Hired assassin
Valentine takes her 'job' very seriously but is not proud of it
Gets few hours of sleeps, so she always looks tired/worn out
Usually works at night, but will never take the mask off unless the job is done
Acts cold hearted, but surprisingly, she is very patient with children and younger peeps
Outside her job she lives a pretty quiet life, tries her best not to get close to anyone, she doesn't want any "distractions"
