Summary
Boris serves as Balalaika's second-in-command and is instantly recognizable by the prominent scar stretching from his right forehead to his left cheek. A calm, broad-built man with a deep Russian accent, he shares a military history with his superior, having also served in Afghanistan. Balalaika continues to address him as "Sergeant" rather than by his name, implying he was her former platoon sergeant. He displays unwavering loyalty and protectiveness toward her, frequently worrying about her safety whenever she chooses to engage in field combat. Although non-canon omakes suggest he was once a weak, girlish-looking boy before joining the army, this detail remains unconfirmed.
