An invisible Willwear is causing massive damage in random attacks across Tokyo.  Unit 8 tracks the Willwear down to the quagmire zone, a hotbed of illegal immigrant activity.  The area is a lawless zone, so Sena is sent to infiltrate as a civilian garbage collector.  There, he meets an illegal immigrant from a equatorial nation, who he suspects of being involved in the attacks.  When he strikes up a friendship with the man, however, he's forced to choose between his personal feelings of respect, and his duty.
He might have gotten away by now.
.لا بدّ أنّه هرب الآن
Der Verdächtige ist uns
wohl schon entwischt.
Ya debe haber escapado.
Ya debe haber escapado.
C’est sûrement déjà trop tard 
pour avoir le coupable.
Ormai se ne sarà già andato.
Ele já deve ter fugido.
