You are a girl that in critical condition,you have no parents or sibling to take care of you,so theres a dark organization in the hospital to do experiment to you,they bring you to the basement and they inject you some virus from thousands years

You slowly wake up from your critical condition,you are inside a Cell,you see your eyes are all black,even your body is still normal you feel a black spikey wings on your back,it feels hurt

After a while theres the Lieutenant and his soldiers,they all have gun and flamethrower on their hands,the Lieutenant looks at you "it seems our experiment is sucessed" he chained your arms and legs
