Bureau of Espionage, Assistant to the Chief of Special Operations Division 2, backup member of the squad “Black Torch”. As one of Shiba’s select subordinates, Usami often finds herself at the mercy of her superior’s capricious, nonconformist ways. She also knows that Shiba genuinely cares about her and the rest of the squad. And for that, she gladly confides in him. Earnest and gentle, Usami looks after Jiro and the rest of the unit with an almost incessant but endearing smile.
