Kara is the young spirit that controls the K.A.R.A. She is able to react to changing situations of battle much faster than anybody could controlling the K.A.R.A. by remote. Because of this, Kara is the only one that can bring out the full combat potential of the K.A.R.A. unit. Unlike the computer that controls the K.A.R.A., Kara has free will and is able to choose her own path in life. After discovering her creator’s intent in making her, Kara runs away to escape the bloody future that she was intended for. Now experiencing the world or the fist time, Kara is determined to create her own future.
