After the incident involving Heath Oslo, the existence of a Japanese-American anti-terrorist organization known as CIRS is now publicly known. CIRS has been rebuilt from scratch and its more hidden features have been transferred to a new agency, SORD (Social Ops, Research & Development). The main purpose of SORD is to train a new generation of spies to protect the country from future threats. To achieve that goal, the organization has built many schools in the country. Mihama Gakuen, which was abandoned due to a sudden closure, has become a specialized training school. That's why this new Mihama Academy brings together different groups of students who are working hard every day to improve their skills. These students endanger their safety by immersing themselves in a variety of out-of-court missions for the benefit of the country.
