Occupy the new airport

Kanagawa New Airport is occupied by the armed group "Beasts" who cover their faces with masks. Musashi, who was once again involved in the incident, asked for help from the administrator, Sakura Izumi, who had been on leave since the incident a year ago. Intelligence analyst Shima and new friends also join in to rescue hostages from the airport and "eliminate" "beasts" that are more dangerous than the "ghosts" in the previous game. On the other hand, Musashi's wife, cardiologist Yuko, who holds a scalpel at Yokohama Bay Hospital, was also involved in a certain incident. There is only one day to rescue the hostages. What is the true face and purpose of the "beasts", and what is the fate of the Musashi family?
