虫籠のカガステル

While working as security, exterminator Kidow responds to an attack by insects, then promises to convey young Ilie to her mother.

As murders come to light, Kidow suspects they're not the work of insects; Ilie goes to to the market where someone steals her bag.

Ilie befriends the leader of the Red Rats; Kidow receives a letter and a map marked with the locations of the murders.

The army prepares to exterminate an insect lurking in the sand beneath E-05; a regretful Qasim volunteers as bait.

Ilie learns from Mario how Kidow's adoptive father, Lazarus, taught him survival lessons in the Cagaster-infested Far East.

A man claiming to be Ilie's father arrives to take her away; she and Kidow try to flee but are ambushed by Acht before they make their escape.
