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.
I wonder if all of Mars's 
silkworms are like this.
‫أتساءل هل كل دود القز في المريخ هكذا
Ich frage mich, ob alle
Seidenspinner auf dem Mars so sind.
Me pregunto si todos los gusanos 
de seda en Marte lucirán así.
Me pregunto si todos los gusanos 
de seda en Marte tendrán ese aspecto.
Je me demande si tous les bombyx
de Mars sont devenus comme ça…
Tutti i bachi da seta marziani sono così, no?
Será que todos os bichos-da-seda
 de Marte são assim?
