Before Eren's mother died, Mikasa promised her that she would protect Eren and keep him out of trouble. But when Eren says he doesn't need her around anymore, everything changes. The next morning Mikasa is nowhere to be found. Levi and Eren must set out to find her, but will they be able to get to her before the titans?

She soared effortlessly through the forsaken town of Zhiganshina, searching frantically. Wall Maria, once standing strong at 50 meters tall had become frail and conquered by the very thing it was made to protect us from. She landed on her feet propelling her body forward into a run towards Eren as fast as she could as Titans clawed at the wall from each side. They stood on top as the wall trembled, struggling to stand, to defend. "We need to distract them so that we can get to that basement" He said staring at where his house, their house, once stood. "This is it," She said, "The end", and with that... she jumped. All Mikasa ever wanted was to have Eren by her side, to keep him safe and live a quiet life, just the two of them. But, with the human race shrivelled and on the cusps of extinction, Mikasa uncovers more truths that will take her life, her very means of living, in a whole new direction. Will this get in the way of her dreams of a quiet life with Eren? "You shouldn't have done it. I never should have let you, how long are you going to keep doing this!" Fists clenched and tears falling down his cheeks, he looked down at the girl worth a hundred soldiers, battered and defeated. "For you," she smiled "A thousand times".
