One month has passed since the monster invasion of Suisei High School by terrorists from the Ghost Nebula organization. Japan has entered winter, and the temperature is turning cold in many areas, especially in the highlands such as Mount Kumotori.
During the afternoon, many Realizers gathered in front of the mountain's entrance. They came from all over Tokyo and numbered at least in the hundreds. The people who came were the senior Realizers and the juniors from high school. They came to that place wearing their combat gear to participate in the joint mission of the three organizations.
Besides the people from official organizations, illegal Realizers also came to the place, and their numbers were not small. They dared to come because the three official organizations promised not to arrest them during the mission unless they did anything suspicious.
