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.
I ate yours before, so I got you these.
.أكلتُ كعكك من قبل، لذلك أحضرت لك هذا
Hier, hab dir die besorgt,
weil ich deine neulich gefuttert hab.
Me comí las tuyas antes,
Me comí los tuyos la otra vez,
J’ai mangé ta bouffe, l’autre fois.
Prima ho preso le tue,
Como eu comi os seus, trouxe isto.
