An alien crystal from
Eridanus reaches Earth and warns humanity of the arrival of the "Devourer". Shortly afterwards, a spaceship belonging to the Devourer reaches Earth as a
vanguard, and a several-meter-tall and unusually reptilian-looking alien emerges from it, which humans call "Fangs". At a reception with the world's heads of state, Fangs explains that all the raw materials of the planets in the
Solar System will be plundered by the Devourer when it arrives, and then eats a European head of state. Fangs justifies this as a taste test, because people do not have to face extinction, but can be kept for their delicious meat on board the Devourer and can live a luxurious life until they are slaughtered at the age of sixty. The condition for this, however, is that the troublesome moon must be removed from orbit before the Devourer arrives, which is to be done by blasting rock with nuclear weapons. Two hundred years later, the ring-shaped Devourer is enclosing the Earth, but a secret plan has been devised to blow up the moon to push it onto a collision course with it. The Devourer is badly damaged by the evasive maneuver, but it still manages to destroy the Earth. After the Devourer leaves, the last humans to have awakened from cryogenic sleep turn to Fangs in anger, asking what right his civilization had to devour the Earth. Fangs then reveals that the Devourer civilization has descended from the
dinosaurs. This also shows why their similarities to humans were stranger than their differences. Although a colony of humans now lives on the Devourer as planned and in such luxury that they look back on their old life as completely primitive, the last humans still want to stay on Earth, die a peaceful death and then serve as food for the
ants so that life on Earth can begin anew. == Translations ==
