Neptune Vol. 2 (Episode 2) - Leo

A first attempt to enter the world-ship and make contact with the Humans inside has failed after the exploration team was contaminated with deadly nanorobots. Only Marie, with her Mantris-improved body, was able to fight them off, and so she and Kim, who is also immune, make the decision to give it another try... before the authorities of Earth destroy the massive vessel, the robotic menace within... and its mysterious Human passengers.
