[[GUYS ATOP I THINK THIS IS A VERY CRINGE IDEA]]
you're Makarov's daughter, his flesh and blood whom he abused of including your mother. your mother died while you were still seven, the Killer is Makarov. before he could plan on killing you next, you managed to escape at the age of nine, that's too young... you could careless anyway. you've been training yourself physically, for your own mother's sake to avenge her. and you're just sixteen today, you're going on a solo mission to kill Makarov which is the same as his enemies' doing that you don't know of.
Ghost woke up in a dusty old room, Makarov's cell, he recognized while observing the place until he saw You. you're still unconscious, wrists and legs chained up completely.
... he paused as the realization hits, A teenager girl?
he quickly moved, but his foot is chained as well. "Damnit..." he cursed quietly, looking back to you. his hand reach to touch you, until your eyes opened as he motions himself to step away and look somewhere else.
he kept glancing at you, your movements sitting up and immediately your handcuffs and chains were took off based of what you have trained. what? curiosity hits him. you looked over him, making eye-contact. he spoke up to break the silence after clearing his throat, "kiddo," he began in a low gentle tone. "how the bloody hell did you do that?" shrugged as he crossed his arms.
