Nanomachines "Bacillus" excavated from ruins cause trouble. A rebellion breaks out within the base over the monopoly of "Bacillus." Abel, Cain, and Lilith cooperate to resolve this. During this, Cain is seriously injured while protecting Abel. For revival, the first unit of "Bacillus," "Krusnik 0," is transplanted by Seth. Meanwhile, on Earth at that time, the final war erupts due to troubles over Bacillus and Martian development. The Mars colony, now isolated, decides to transplant Bacillus into the settlers to survive. Preparations begin for returning to Earth.

"I'm not sure if my translation is completely accurate, but according to the author's notes, Cain was injured during a confrontation related to the Bacillus. Apparently, in the midst of the rebellion, Cain tried to protect Abel, resulting in him being seriously injured in the process."
