Dimitri was a captured as a soldier by the Arume and was made prisoner, then later a slave. One day Aki, when she was still in the Arume, bought Dimitri off his owner, and Dimitri has been loyal to her ever since.
Dimitri for the most part looks very plain, other than a few scars that go across his face that he got from the time he was a slave. He mostly just wears some resistance uniform.
Dimitri doesn't talk much, and is a very focused man. He is very loyal to Aki, and his objective always comes first for him. He is for the most part very serious, but after completing a mission or objective he is a good drinking buddy.
