Akiko Yosano is the indispensable physician of the Armed Detective Agency, her short hair always secured with a distinctive butterfly clip. Her rare healing ability, "Thou Shalt Not Die," is a double-edged sword that requires a patient to be brought to the brink of death before she can mend them, a fact that terrifies her own colleagues. While she enjoys flowers and Japanese sweets, she has a sharp disdain for male chauvinism, a trait likely forged in her traumatic past as a child medic during the Great War. Despite her cheerful and modern demeanor, there's a profound sorrow behind her eyes, a remnant from when a grateful soldier first called her an angel and later, an angel of death.
