After being surrounded by the thread that a Terraformar with the powers of a silkworm laid out, Shokichi remembers Akita Nanao. Shokichi regrets the fact that they had to leave her body behind on Mars after they had killed her during the Bugs 2 mission. Now, he wants to get revenge. Will Shokichi be able to restart the clock that had stopped twenty years ago? Meanwhile, The No. 3 Division is within the pyramids and find something that shouldn't be there, and suddenly, a deafening sound can be heard throughout Mars.
Not only is nothing pursuing us, 
but nothing was guarding this place, either.
‫ليس أن لا أحد يطاردنا وحسب، بل لا أحد يحرس المكان أيضًا
Wir werden nicht verfolgt
und es gab keine Wachen.
No nos persiguen. Tampoco 
protegen este lugar.
No nos persiguen. Tampoco 
protegen este lugar.
Il n’y a ni poursuivants ni gardes.
Non solo non ci ha seguito nessuno,
 ma non c'è nessuno di guardia.
Não só ninguém nos perseguiu, 
como não há guarda algum.
