Summary

Twenty years ago, Shokichi Komachi was part of the Bugs 2 mission to Mars that discovered Terra Formars, human-cockroach hybrids that resulted from a terraforming accident. Shokichi was one of only two survivors. Now, the AE virus that came from Mars is raging wildly on earth. Shokichi boards the spacecraft Annex 1 to go back to Mars to find a sample in order to create a vaccine. They will face an unanticipated accident, a multinational conspiracy, and even more advanced Terra Formars.
