Akiko Yosano’s lore centers on her traumatic past as an 11-year-old wartime nurse recruited by Mori Ogai, who exploited her rare healing ability, "Thou Shalt Not Die," to create an endless cycle of recovery for soldiers. Because her power only works on people on the brink of death, she was forced to watch soldiers get brutally mangled repeatedly so she could heal them back into battle, earning her the terrifying moniker "The Angel of Death." This psychological torture drove the soldiers insane, culminating in the suicide of a close soldier friend and causing Yosano to experience a complete mental breakdown and destroy the base. Years later, after being locked away and nearly reclaimed by Mori, she was rescued by Ranpo Edogawa and Fukuzawa Yukichi, who gave her a new purpose and a safe haven within the Armed Detective Agency
