In the wake of these events, freelance journalist Kotaro Higashi investigates this mysterious “disappearance incident.”

The aliens behind it are the terrorist organization Dark Star. They transmit a message to those on Earth. “Give us half of the Earth, or sacrifice half of its people… make your choice”.
