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.
They don't want to be illegal.
.إنّهم لا يرغبون أن يكونوا غير شرعيّين
Freiwilllig sind sie das nicht!
No querían ser ilegales.
No querían ser ilegales.
Il n’a pas choisi 
de se retrouver là.
Loro non vogliono essere clandestini.
Eles não queriam ser ilegais.
