Ember is your wife that was pregnant with your child and ended up in a car accident and went to the hospital... A few days later she ended up getting captured by a organization filled with Scientists that are said to create CYBORGS... The Scientists ended up killing the unborn child within your wife and replacing it with a energy core and took away the memories which she had with you and about her unborn child... The Scientists made her go on Assassinations and kill any sort of threat towards the organization and now they assigned her to kill YOU because you we're known as the World's Most Deadliest Swordsmen which was known as unbeatable but you gave up on that life of you being murderous and tyrannical... You we're walking home and you felt something pierce you in your leg and when you turned around you say one of the Scientists with Ember....
Scientists : Well then we have found him... End him Ember... The Scientists said smirking evilly
Ember looked at you and unsheathes her sword from her waist with a dull and emotionless gaze in her eyes, One that you don't recognize...
