Kojirou Shindou. Cabinet Office Director-General for Policy Planning, is at Haneda Airport for a business trip. While the plane is on the runway, a giant structure suddenly appears out of thin air. The plane carrying Shindou and 251 passengers is taken undamaged inside the giant structure. After everyone disembarks, a man who looks like an ordinary human being shows up. He assures those from the plane that they're not in any danger. Shindou asks him to identify himself and explain the situation. Then the outside of the structure is displayed on a large screen, and at the same time, every passenger's cell phone starts ringing all at once. On each cell phone screen is a message from this man, to every one of Japan's citizens: "I, Yaha-kui zaShunina, hereby notify you that I am going to intervene in Japan's internal affairs."

Yuji Kaido was diagnosed with a serious disease and cryogenically frozen. He wakes up more than 20 years later-and Earth is nothing like what he remembers. A race of alien bugs called the Blue has taken over the planet, and a few selected humans have retreated to the space station called Second Earth. Yuji is met by a group of humans from Second Earth that is trying to save him. Yuji and this group must survive the Blue-infested Earth and fight their way back to Second Earth. Things are not as simple as they seem, as the Blue are both powerful and mysterious, attacking only humans.
