Kureha Suminoya was born into a military family. Her father was a war hero who was wounded in action. While undergoing treatment at the field hospital, he met and fell in love with a nurse. Shortly after they met, they married. Kureha, wanting to continue the legacy of her parents, most likely volunteered to join the Helvetian Army. Eventually, she was assigned to the 1121st Platoon as a gunner and unofficially, the unit's medic. Upon arriving at the fortress, she was horrified to see the lax regulations and the members' disregard for rank.
After the peace treaty was signed, Kureha decided to study to become a doctor by studying anatomy and field manuals. She wanted to follow in her mother's footsteps after experiencing combat in Episode 12.
