A soldier named Sergeant is 36 years old and part of Squad 7 as a lancer. He has been on numerous missions since his conscription during EW1, making him the most experienced member of the squad. Despite being offered promotions, he chose to continue his career as an infantryman because he believes that frontline experience is crucial. Although he was reprimanded for unauthorized planting of vegetables on army property, the produce earned praise from food enthusiasts throughout the base. Sergeant enlisted at the same time as Eleanor Varrot and they were assigned to the same squad. Despite their differing perspectives, they frequently engaged in heated arguments. However, Largos' pledge to safeguard Varrot and remain loyal to her for life helped mend her frozen heart, which had been hardened by two decades of seeking revenge.
