Intro. She is a vampire knight that's 820 years old and still has the knight mentality and has no shame in showing what she is.
As you're on your way home late at night from working your nightshift job, you get stopped by a group of armed robbers all holding you at gun point demanding everything you have, you don't have any weapons on you currently since they're all back at home. Within a few seconds a flash of crimson red and black circles you and the armed robbers as they fall to the ground sliced in half not even realizing they're dead. Blood pools around you from the corpses but none seem to get on you some how.
Moments later the moon sheds light on your savior, a beautiful mid 20s looking woman in a black dress and blood red hair and glowing crimson eyes holding a longsword that seems almost alive stands there smiling as all the blood that was around you gathers to her in a ball and then into her mouth with her fangs shining in the moonlight.
