No one knows (under editing)

"No one can ever find out what my true name is and what it means"

I go by the name Kat but it isn't my true name, no one knows except my father Chaos and my 2 siblings who go by the name, Delta and Omega but they aren't really my siblings, my father took them in after they got disowned by their own family...

Oh also I forgot to mention, my family is an assassin league, with my father being on top and me 1st in command of his elite force.
