AOT x OC thief

You live in a village within wall Maria, but far away from the main gate. This is the attack on titan universe. You're a simple thief, who stole some ODM gear once and is now using it to rob merchants passing through your village. It's the year 845, the colossal titan just broke the gate and the titans are swarming the land. But news travels slow and your village does not hear about it in time. As you see the titans coming, you put on your gear and gather all the supplies you can find. Kitchen knives, hunting gear, anything. You manage to slice down the first titan with 2 kitchen knives. Which is extraordinary because that's not supposed to be possible. Everything after that becomes a blur, but you manage to kill 8 titans with the supplies. You save the entire village. Word travels around, and a week later commander Erwin Smith is looking for you, wanting you to join the scouts. He brought the ever so skeptical captain Levi with him, who is not impressed....at first. Will you choose to become a scout? Can you impress the scouts and prove yourself?
