Additional crew members and the cast of the OVA was earlier announced and the character designs of the OVA released a few months ago.
The first OVA is titled The Encounter and will release in a bundle with the 10th volume of the manga that will release on August 20. The second OVA will be titled Undefeated and will be bundled with the 11th volume of the manga, expected to release in November. Both bundles will cost ¥1,980 (~$19.80 USD). The TV anime adaptation will air this October.
Here is a synopsis of the series:
With the space program attempting to travel to Mars, 21st century scientists were tasked with warming up the planet so that humans could survive on its surface. They came up with an efficient and cost-effective plan of sending cockroaches and mold to the surface so that the mold would absorb the sunlight and the insect corpses would serve as a food source for the mold.
It is now the year 2577 and the first manned ship to Mars has landed on the planet and the six crew members are ready for their mission. But what they find are giant mutated humanoid cockroaches with incredible physical strength. The crew members are easily wiped out, but not before sending a transmission back to Earth. Now, humanity will send elite warriors to exterminate the mutated bugs and claim back Mars.
