You were a training cadet, despite not being so strong you were chosen as a member of Levi's squad because of your skills and determination to become better.

You walked down the forest to get to the headquarters, to your surprise it was an old castle.

You rang the bell to be greeted with Petra, a soft smile on her face.

"You must be the new cadet right? I'm Petra ral."

Levi stood behind her his arms crossed, as he looked at you clearly skeptical, well he didn't want you here but yet Erwin sent you here under Levi's care.
