Attack on Titan- Edge of Extinction

PROLOGUE

     "How can this be?" I say to myself as I look up. A giant red hand is perched upon trost districts wall. The face of an enormous steaming titan ascends above the 50 meter wall.
It looks at us humans as if to say

  I've got you in the palm of my hand,
      and you worthless beings can't
              do anything about it

      All of a sudden I am blown back and rocks are flying all around me. I land on my back, and when I look up I see a giant rock about to crush me. Suddenly a man, with neat black hair and a stern face, flies in, grabs me, and uses his 3d maneuver gear to grapple up to a building top.
  "Stay here for a second" he sais.
He's sets me down and looks at two titans that are headed towards us.
  "How did they get inside the walls?" He asks.
  "The steaming titan. It kicked a hole in the wall!"
  "Steaming titan?"
I start to point and then realise it's not there.
  "A giant titan appeared and kicked the wall. I'm assuming that's where the got in." I say as I stand up.
  "I'll take care of these titans" he says.
He then uses the gas chamber to fly right at the titans. One of them tries to grab him, but he grabbed the titans arm and used it to jump behind it. He hooks the back of its neck and cuts a clean chunk off it's nape. The other went to bite him, and the man grappled into it's mouth
  "What hell is he thinking?" I say.
At that moment he cuts through the back of the titans throat and flies out coming back to where I was.
  "Disgusting!" he says when he lands.
  "Why did you do it?"
  "If I hadn't it would have bit me in half." He told me. "Lets get out of here" he says. He grabs me again and jumps off the builing.
  "Where is your family?"
  "I havn't got any." I tell him
He stopped.
  "Your name?"
  "I, I..... don't have one." I say looking down.

  "Cheer up brat!" he shouts.
I look up, and he looks away from me.
  "You can live with me." He says
I look at him.
  "Thank you!" I yell and go to hug him
  "not now brat." he says as he picks me up and flies off once again.
    
Five years pass. I'm a soldier now.
The man from that day took me in. His name is levi. He game the only three things I've ever wanted. A home, a family, and most of all. A name. That name, is Akitama
