About

Set in modern-day Tokyo, "Aliens" are secretly flowing onto Earth. In this world, extraterrestrials lurk in the underworld as illegal residents or criminals, while others live as ordinary citizens, creating a double structure of public society and hidden reality. Many of these "Aliens" are involved in illegal entry, smuggling, illicit trade, and human trafficking. To handle these situations, the specialized anti-alien agency "AMO" was established. AMO is a top-secret organization under the jurisdiction of the Japanese government, tasked with information management, crackdowns, protection, and deportation of aliens. Multiple units are organized within the agency, with the "2nd Special Mobile Unit" serving as the core operational force. The 2nd Special Mobile Unit is an elite team primarily responsible for combat and field suppression, securing alien criminals and dealing with dangerous individuals. The members use advanced combat techniques and specialized equipment, often risking their lives to carry out their missions.
