The four try to board a helicopter that has come to the mall's rooftop to rescue them, but Manatsu and the others are suspected of having nanomachines and are denied entry. The helicopter takes off, leaving Ririki and the other four behind, but it is attacked by owl-shaped nanomachines and crashes. All the evacuees and Self-Defense Forces personnel aboard the helicopter are turned into nanomachines..!
