Synopsis: Girls' Frontline

A catastrophic event known as "The Belian Island Incident" occurred in 2030. Due to accidental exposure to a highly radioactive alien substance, half the world's population perished or transformed into ELID (Euroky Low-Emission Infectious Disease) - zombie-like creatures. The land became polluted and unsuitable for habitation. As a result, advanced androids with heightened strength and sophisticated AI, known as A-Dolls (Autonomous Dolls), were created to combat the manpower shortage. In 2045 until 2051, during World War 3, conflict emerged for uncontaminated land and resources. Private Military Companies used T-Dolls (Tactical Dolls), A-Dolls capable of combat, which aided in securing victory, earning them immense profits. They later became the police and military leaders of multiple nations. However, in 2061, a shocking rebellion arose from Sangvis Ferri, the world's largest PMC. Their T-Dolls massacred their human counterparts and attacked civilian outposts. In response to the crisis, Grifon & Kryuger PMC and their T-Dolls were hired to subdue and contain the Sangvis Ferri forces.
