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.
But we got closer 
 because of a moth, as well.
‫لكننا تقرّبنا من بعضنا بسبب عثّة أيضًا

Aunque creo que nos conocimos 
gracias a una polilla.

Se bem que foi por causa do 
bicho-da-seda que nos aproximamos.
