S01E01 Symptom: Mutation
It has been twenty years since the tragedy of Bugs 2 and is now 2619. In order to save his childhood friend, Yuriko, from an unknown illness, Hizamaru Akari was fighting in an underground arena...
Shokichi and his division make it safely to Mars, however they are immediately attacked by the terraformars. The other divisions are also attacked, and since there is only one terraformar in sight for each division, they feel that the threat is minimal.
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.
