Boris

ボリス

Boris serves as Balalaika's second-in-command. He is easily recognizable by a large scar that stretches from the right side of his forehead down to his left cheek. He is a calm, broad-built man who speaks with a deep Russian accent. Like Balalaika, he also served in Afghanistan. She continues to address him as "Sergeant" instead of by his name, which suggests he was her former platoon sergeant. He is deeply loyal and protective of Balalaika, frequently worrying about her safety when she chooses to engage in field combat. In an omake, he is depicted as having been a weak, girlish-looking boy prior to joining the army (though this remains unconfirmed, as omakes are non-canon).
