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.

When he strikes up a friendship with the man, however, he's forced to choose between his personal feelings of respect, and his duty.
And from now on, if you take
anything, go through us.
ومن الآن فصاعدًا، عليك أن تمرّ

E a partir de agora, tudo o que
