Terra Formars: Bugs 2-hen

In 2599, the BUGS 2 expedition reaches Mars after the loss of humanity's first manned mission. Cockroaches and moss were once sent to make the planet habitable, but the new crew discovers that the insects have evolved into powerful humanoid creatures violently hostile to humans.

The expedition members, including Shokichi Komachi and Nanao Akita, have undergone experimental surgery granting them insect-based abilities. Their extermination assignment becomes a desperate struggle to survive an enemy far beyond their expectations. As casualties mount, the crew must use their altered bodies while confronting uncertainties that threaten both their mission and their trust in one another.
